Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and device.

Background

The terminal device may obtain a Channel State Information (CSI) report (report) by performing channel measurement on the CSI reference resource, and the terminal device may obtain CSI obtained by encoding the CSI report and may send the CSI to the network device, so that the network device may schedule data for the terminal device according to the received CSI. Therefore, the more timely the terminal device sends the CSI to the network device, the more accurately the network device can allocate resources, thereby improving the utilization efficiency of system resources.

Before encoding a CSI report, a terminal device ranks the CSI reports, and at present, the terminal device ranks the CSI reports in order of smaller index to larger index.

If the terminal device maps the CSI to a Physical Uplink Control Channel (PUCCH) for transmission, since the PUCCH is a channel with limited capacity, when the channel capacity of the PUCCH is limited, the PUCCH needs to perform rate matching, that is, the length of an output sequence is limited, and if the sequence obtained after the ordering is too long, some information is discarded from the rear of the sequence. Since the terminal devices are sorted in the order of the indexes of the CSI reports from small to large, the smaller the index, the higher the priority of the CSI report, and what may be discarded is the information of the CSI report with the larger index.

In addition, in a New Radio (NR) system of the fifth generation mobile communication system (5G), CSI is further divided into a CSI first part (part 1) and a CSI second part (part 2), where CSIpart1 may indicate specific contents of CSI part2, and whether CSI is transmitted on PUCCH or on Physical Uplink Shared Channel (PUSCH) may include CSIpart1 and CSIpart 2. In the case of including CSI part2, if CSI part2 exceeds the code rate, information needs to be dropped according to priority, that is, information with low priority is dropped. For the CSI part2, the terminal device is also sorted according to the order from small to large of the index of the CSI report, and the index of the CSI report represents the priority, so that similarly, the information of the CSI report with a larger index may be discarded.

It can be seen that, currently, when information is discarded, reliability of a CSI report is not considered, the discarded information may belong to a CSI report with higher reliability, and such information may be more important, that is, the current sorting manner may cause more important information to be discarded.

Disclosure of Invention

The embodiment of the application provides a communication method and equipment, which are used for reducing the possibility of discarding important information.

In a first aspect, a communication method is provided that is executable by a communication device, such as a terminal device. The method comprises the following steps: determining at least two CSI report sets, wherein each CSI report set comprises at least one CSI report, and the at least two CSI report sets comprise a first CSI report set corresponding to a first block error rate and a second CSI report set corresponding to a second block error rate; and generating uplink control information bit sequences corresponding to the at least two CSI report sets according to a mapping ordering rule, wherein the mapping ordering rule comprises the sequence from the first CSI report set to the second CSI report set.

Accordingly, in a second aspect, a communication method is provided that is executable by a communication device, such as a network device, e.g., a base station. The method comprises the following steps: receiving an uplink control information bit sequence; determining at least two CSI report sets through the uplink control information bit sequence, wherein each CSI report set of the at least two CSI report sets comprises at least one CSI report, the at least two CSI report sets comprise a first CSI report set corresponding to a first block error rate and a second CSI report set corresponding to a second block error rate, and the sequence of the CSI report sets corresponding to the bits in the uplink control information bit sequence comprises the sequence from the first CSI report set to the second CSI report set.

In this embodiment of the present application, the uplink control information bit sequence may be generated according to a mapping ordering rule, where the mapping ordering rule includes an order from a CSI report corresponding to a first block error rate to a CSI report corresponding to a second block error rate, and the block error rate generally can indicate reliability of the CSI report, for example, the lower the block error rate, the higher the reliability, and the higher the reliability, the more important the reliability. Therefore, in the embodiment of the application, the CSI reports are sorted according to the block error rate, and if the CSI report with a low block error rate is sorted in front, the information of the CSI report with a low block error rate is discarded as less as possible, so as to ensure that the more important information can be transmitted successfully as much as possible.

In one possible design, in the uplink control information bit sequence, a mapping position of a CSI report included in the first CSI report set is above a mapping position of a CSI report included in the second CSI report set.

If different CSI reports have different block error rates, the mapping positions in the uplink control information bit sequence are also different. For example, the first block error rate is smaller than the second block error rate, or the priority of the first block error rate is higher than the priority of the second block error rate, then in the uplink control information bit sequence, the CSI report included in the first CSI report set corresponding to the first block error rate is mapped on the upper portion of the CSI report included in the second CSI report set corresponding to the second block error rate, so that the CSI report included in the first CSI report set can be transmitted as much as possible, discarding due to a mapping position after the mapping position is avoided, and the success rate of high-reliability information transmission is improved.

In one possible design, in the uplink control information bit sequence, the mapping position of the wideband CSI and/or the subband CSI of the CSI report included in the first CSI report set is above the mapping position of the wideband CSI and/or the subband CSI of the CSI report included in the second CSI report set; or, the uplink control information bit sequence includes at least two of the following items: the mapping position of wideband CSI of CSI reports included in the first CSI report set is above the mapping position of wideband CSI of CSI reports included in the second CSI report set, the mapping position of wideband CSI of CSI reports included in the second CSI report set is above the mapping position of subband CSI of CSI reports included in the first CSI report set, and the mapping position of subband CSI of CSI reports included in the first CSI report set is above the mapping position of subband CSI of CSI reports included in the second CSI report set.

It can be simply understood that, in the uplink control information bit sequence, mapping may be performed according to the block error rate corresponding to the CSI report, and this mapping manner may map information with a smaller block error rate or a higher priority of the block error rate to the upper portion as much as possible, so as to ensure a success rate of high-reliability information transmission; or, the wideband CSI may be mapped according to the block error corresponding to the CSI report first, and then the subband CSI may be mapped according to the block error corresponding to the CSI report first, which is a smaller modification to the existing protocol and easier to adapt to the existing mapping rule.

In one possible design, the first CSI report set and the second CSI report set include at least one of: the first CSI report set comprises CSI reports with report indexes smaller than those of the second CSI report set; the CSI reports included in the first CSI report set comprise wideband CSI, and/or the CSI reports included in the second CSI report set comprise sub-band CSI; the CSI reports included in the first CSI report set comprise CSI part1, and/or the CSI reports included in the second CSI report set comprise CSI part 2; and the CSI report included in the first CSI report set is carried on a PUCCH, and/or the CSI report included in the second CSI report set is carried on a PUSCH.

In this embodiment, the terminal device has already processed according to the block error rate when obtaining the CSI report through measurement, and may directly sort when sorting according to the mapping sorting rule. This embodiment can ensure that CSI reports of important target block error rates are protected without modifying the definition of the existing protocol.

In a third aspect, a communication method is provided that is executable by a communication device, such as a terminal device. The method comprises the following steps: determining a CSI report, wherein the CSI report comprises CSI part1 and/or CSI part2, and the CSI report at least corresponds to a first block error rate and a second block error rate; and sending the CSI report.

Accordingly, in a fourth aspect, a communication method is provided that is executable by a communication device, such as a network device, e.g., a base station. The method comprises the following steps: receiving a CSI report; and determining CSI part1 and/or CSI part2 included in the CSI report through the CSI report, wherein the CSI report at least corresponds to a first block error rate and a second block error rate.

In this embodiment of the present application, a CSI report corresponds to at least two block error rates, where the at least two block error rates include a first block error rate and a second block error rate, and then, under the condition that it is ensured that the content included in the CSI report corresponds to at least two block error rates, the CSI report may be ranked according to the block error rates, and it may be considered that the CSI report determined in the third aspect or the CSI report received in the fourth aspect is a CSI report ranked according to the method provided in this embodiment of the present application. If the information with low block error rate is arranged in front, the discarding of the information with low block error rate can be reduced as much as possible, and the successful transmission of the more important information can be ensured as much as possible.

In one possible design, the CSI report includes the CSI part1 and the CSI part2, the CSI part1 and the CSI part2 include at least one of: the CSI part1 includes the first CQI and/or the second CQI, and the CSI part2 includes the third CQI and/or the fourth CQI; the CSI part1 includes the third CQI and/or the fourth CQI, the CSI part2 includes the first CQI and/or the second CQI; wherein the first CQI and the fourth CQI are CQIs of a first transport block, the second CQI and the third CQI are CQIs of a second transport block, and/or the first CQI and the fourth CQI are wideband CQIs, the second CQI and the third CQI are sub-band CQIs; and the first CQI and the second CQI correspond to the first block error rate, and the third CQI and the fourth CQI correspond to the second block error rate.

In this design, all embodiments are contemplated in which the CSI report includes CSI part1 and CSI part2, CSI part1 and CSI part2 both include CQI, and the CSI report corresponds to at least two block error rates.

In one possible design, the CSI report includes the CSI part1, the CSI part1 includes at least one of: the CSI part1 includes the first CQI and the fourth CQI; the CSI part1 includes the second CQI and the third CQI; wherein the first CQI and the fourth CQI are CQIs of a first transport block, the second CQI and the third CQI are CQIs of a second transport block, and/or the first CQI and the fourth CQI are wideband CQIs, the second CQI and the third CQI are sub-band CQIs; and the first CQI and the second CQI correspond to the first block error rate, and the third CQI and the fourth CQI correspond to the second block error rate.

In this design, the CSI includes CSI part1, which is understood as that the CSI report includes CSI part1 only, and then, in the case of including CSI part1 only, the CQI included in CSI part1 needs to correspond to the first block error rate and the second block error rate, so that the condition that the CSI report can correspond to the first block error rate and the second block error rate is satisfied.

In one possible design, the CSI report includes the CSI part2, the CSI part2 includes at least one of: the CSI part2 includes the first CQI and the fourth CQI; the CSI part2 includes the second CQI and the third CQI; wherein the first CQI and the fourth CQI are CQIs of a first transport block, the second CQI and the third CQI are CQIs of a second transport block, and/or the first CQI and the fourth CQI are wideband CQIs, the second CQI and the third CQI are sub-band CQIs; and the first CQI and the second CQI correspond to the first block error rate, and the third CQI and the fourth CQI correspond to the second block error rate.

In this design, the CSI includes CSI part2, which is understood as that the CSI report includes CSI part2 only, and then, in the case of including CSI part2 only, the CQI included in CSI part2 needs to correspond to the first block error rate and the second block error rate, so that the condition that the CSI report can correspond to the first block error rate and the second block error rate is satisfied.

In several designs as above, the order of the CQIs in the CSI report may not be limited, for example, the order of the CQIs in the CSI report may be random, or may be ordered according to at least one of the following rules:

sorting according to the block error rate corresponding to the CQI;

sorting according to the transmission blocks corresponding to the CQI; and the combination of (a) and (b),

ordered in order from wideband CQI to sub-band CQI.

In addition, for the sub-band CQI, an even sub-band CQI and an odd sub-band CQI may be further included, and the ordering rule may further include: ordered in order from even sub-band CQI to odd sub-band CQI.

In one possible design, the first block error rate and the second block error rate include at least one of: the first block error rate has a higher priority than the second block error rate; the first block error rate is less than the second block error rate; the priority of the first block error rate is lower than the priority of the second block error rate; and the first block error rate is greater than the second block error rate.

That is, the embodiment of the present application does not limit the relationship between the first block error rate and the second block error rate.

In a fifth aspect, a communication method is provided that is executable by a communication device, such as a terminal device. The method comprises the following steps: determining first information, wherein the first information is used for determining CQI; determining a CQI index corresponding to the CQI according to the first information; wherein the determining the first information includes at least one of: determining the first information according to the received downlink control information DCI; determining the first information according to the resource of the CQI; and determining the first information according to the information of the CSI containing the CQI.

The currently supported way for the device to notify the terminal device of the CQI table is to perform notification by using a high layer signaling, and before the terminal device receives a new high layer signaling notification, the terminal device uses the previous CQI table by default. The URLLC service has high requirement on time delay, and the network equipment can flexibly and dynamically select the used CQI table according to the actual condition of the terminal equipment when the URLLC service arrives. However, since the used table is notified to the terminal device through the high layer signaling, and the high layer signaling is semi-static, the terminal device cannot be notified of the selected CQI table in time, and the terminal device will continue to use the CQI table selected before. In this embodiment of the present application, the terminal device may determine the first information in a dynamic manner (whether the first information is determined according to the received DCI, the first information is determined according to the resource where the CQI is located, or the first information is determined according to the information of the CSI including the CQI, which may be considered as a dynamically determined manner), so that the terminal device can timely know the selected CQI table without using high-layer signaling, thereby completing communication.

In one possible design, the first information may be determined based on the received DCI, and the first information may include at least one of: an MCS index indicated by the DCI; a coding rate indicated by the DCI; a scheduled transport block size indicated by the DCI; and a feedback time interval indicated by the DCI, wherein the feedback time interval is a time interval from the DCI to a time domain resource carrying the CQI.

The first information can comprise a plurality of types, and one or more types can be selected during specific application, so that the method is flexible.

In one possible design, the first information includes an MCS index indicated by the DCI, a value of the MCS index indicated by the DCI belongs to at least one of multiple value sets, where the multiple value sets include a first value set and a second value set, a CQI index corresponding to the CQI corresponding to an index of the MCS included in the first value set is a first CQI index, and a CQI index corresponding to the CQI corresponding to an index of the MCS included in the second value set is a second CQI index.

For example, the larger the MCS index is, the better the channel quality of the terminal device is indicated, and when the terminal device only supports the URLLC service, for such a case, the terminal device may use the CQI with a lower block error rate or a higher priority of the block error rate for feedback, so as to achieve higher reliability. If the MCS index is smaller, the channel quality of the terminal equipment is poor, and the terminal equipment only supports the URLLC service, the terminal equipment can adopt the CQI with higher block error rate or lower priority of the block error rate to feed back so as to ensure the basic reliability.

In one possible design, the first information includes a coding rate of an MCS indicated by the DCI, the coding rate of the MCS indicated by the DCI belongs to at least one of a plurality of code rate sets, the plurality of code rate sets include a first code rate set and a second code rate set, a CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the first code rate set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the second code rate set is a second CQI index.

For example, the larger the code rate of the MCS is, the better the channel quality of the terminal equipment is indicated, and when the terminal equipment only supports the URLLC service, for such a case, the terminal equipment may adopt the CQI with a lower block error rate or a higher priority of the block error rate, so as to ensure higher reliability. If the code rate of the MCS is smaller, it indicates that the channel quality of the terminal equipment is required to be poor, and the terminal equipment only supports the URLLC service, the terminal equipment can adopt the CQI with higher block error rate or lower priority of the block error rate to perform feedback, so as to ensure the basic reliability.

In one possible design, the first information includes a scheduled transport block size indicated by the DCI, the scheduled transport block size indicated by the DCI belongs to one of a plurality of transport block size sets, the plurality of transport block size sets include a first transport block size set and a second transport block size set, a CQI index corresponding to the CQI corresponding to the scheduled transport block size included in the first transport block size set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the scheduled transport block size included in the second transport block size set is a second CQI index.

For the services, a CQI table with a low block error rate or a high priority of the block error rate may be used to ensure reliability. If the larger the size of the scheduled transport block is, the service is not very urgent, and the requirement of such service on reliability is not very high in general, then for such service, a CQI table with higher block error rate or lower priority of block error rate may be used.

In one possible design, the first information includes a feedback time interval indicated by the DCI, where the feedback time interval indicated by the DCI belongs to at least one of a plurality of time interval sets, where the plurality of time interval sets include a first time interval set and a second time interval set, a CQI index corresponding to the CQI corresponding to the feedback time interval included in the first time interval set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the feedback time interval included in the second time interval set is a second CQI index.

For example, a shorter feedback time interval indicates a more urgent service, which may be URLLC service or other more urgent service, and for such a service, a CQI with a lower block error rate or a higher priority of the block error rate may be used to ensure reliability. If the longer the feedback time interval, the less urgent the service is, and the requirement of such service for reliability is generally not very high, then for such service, CQI with higher block error rate or lower priority of block error rate can be used.

In one possible design, the first information is determined according to a resource where the CQI is located, and the first information includes at least one of: a carrier where the resource where the CQI is located; a cell where the resource where the CQI is located; BWP where the resource where the CQI is located; a TAG where a resource where the CQI is located; the PUCCH group where the resource where the CQI is located; a PUCCH format corresponding to a resource where the CQI is located; the subcarrier interval of the resource where the CQI is located; the waveform of the resource where the CQI is located; and the time domain length of the resource where the CQI is located.

In one possible design, the first information includes a carrier where the resource where the CQI is located, the carrier where the resource where the CQI is located is at least one of a plurality of carriers, the plurality of carriers includes a first carrier and a second carrier, a CQI index corresponding to the CQI corresponding to the first carrier is a first CQI index, and a CQI index corresponding to the CQI corresponding to the second carrier is a second CQI index.

For example, the system may carry the URLLC service on a specific carrier for transmission, and carry other services on other carriers for transmission, so if the CQI is transmitted through the carrier carrying the URLLC service, it indicates that the CQI belongs to the URLLC service, and the URLLC service requires higher reliability, the CQI table with lower BLER may be selected, whereas if the CQI is transmitted through the carrier carrying other services, it indicates that the CQI belongs to other services except the URLLC service, and the reliability requirements of the other services are not higher than the URLLC service, the CQI table with higher BLER may be selected.

For the first information, the cell where the resource of the CQI is located and the BWP where the resource of the CQI is located are included; when at least one of the TAG where the resource where the CQI is located, the PUCCH group where the resource where the CQI is located, the PUCCH format corresponding to the resource where the CQI is located, the subcarrier interval of the resource where the CQI is located, and the waveform of the resource where the CQI is located is selected, the implementation manner is similar to the implementation manner of the carrier where the first information includes the resource where the CQI is located, and details are omitted.

In one possible design, the first information includes a time domain length of a resource where the CQI is located, the time domain length of the resource where the CQI is located belongs to at least one of a plurality of time domain length sets, the plurality of time domain length sets include a first time domain length set and a second time domain length set, a CQI index corresponding to the CQI corresponding to the time domain length of the resource where the CQI is located that is included in the first time domain length set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the time domain length of the resource where the CQI is located that is included in the second time domain length set is a second CQI index.

For example, the shorter the time domain length of the resource where the CQI is located, indicates that the service is more urgent, such service may be a URLLC service, or other more urgent service, and for such service, the CQI with a lower block error rate or a higher priority of the block error rate may be used to ensure reliability. If the longer the time domain length of the resource where the CQI is located is, it indicates that the service is not very urgent, and the requirement of such service on reliability is generally not very high, then for such service, a CQI with a higher block error rate or a lower priority of the block error rate may be used.

In one possible design, the first information may be determined based on information including CSI for the CQI, the first information including at least one of: the length of the time domain resource occupied by the CSI; content of the CSI; and, the number of bits of the CSI.

In one possible design, the first information includes a length of a time domain resource occupied by the CSI, the length of the time domain resource occupied by the CSI belongs to at least one of a plurality of time domain length sets, the plurality of time domain length sets include a third time domain length set and a fourth time domain length set, a CQI index corresponding to the CQI corresponding to the length of the time domain resource occupied by the CSI that is included in the third time domain length set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the length of the time domain resource occupied by the CSI that is included in the fourth time domain length set is a second CQI index.

For example, the shorter the time domain length of the resource where the CSI is located is, the more urgent the service is, such a service may be a URLLC service, or other more urgent services, and for such a service, the CQI with a lower block error rate or a higher priority of the block error rate may be used to ensure reliability. If the longer the time domain length of the resource where the CSI is located is, it indicates that the service is not very urgent, and the requirement of the service on reliability is not very high, for the service, the CQI with a higher block error rate or a lower priority of the block error rate may be used.

In one possible design, the first information includes content of the CSI, the content of the CSI includes at least one of a plurality of contents, the plurality of contents includes a first content and a second content, a CQI index corresponding to the CQI corresponding to the first content is a first CQI index, and a CQI index corresponding to the CQI corresponding to the second content is a second CQI index.

For example, the content of the CSI indicates CSI part included in the CSI. Because the priority of the CSI part1 is generally higher than that of the CSI part2, if the content of the CSI only includes CSI part1, it indicates that there may be a more urgent service, and such a service may be a URLLC service, or other more urgent services, for such a service, a CQI with a lower block error rate or a higher priority of the block error rate may be used to ensure reliability. If the content of CSI includes CSI part2, indicating that the service is not urgent and the requirement for reliability of such service is not high, then for such service, a CQI with a higher block error rate or a lower priority for block error rate may be used.

Or, the content of the CSI indicates the content of RSRP, PMI, RI, or the like included in the CSI. Since RSRP, PMI, and RI are slow content, if the CSI includes these contents, it turns out that the CSI is not urgent for feedback, so a CQI with a higher block error rate or a lower priority for block error rate may be employed.

Or, the content of the CSI indicates the content of wideband CSI and/or subband CSI included in the CSI. Generally, the priority of wideband CSI is higher than that of sub-band CSI, if the content of CSI only includes wideband CQI and/or wideband PMI, it indicates that the service is urgent, and such service may be URLLC service or other urgent service, and for such service, CQI with lower block error rate or higher priority of block error rate may be used to ensure reliability. If the content of the CSI includes sub-band CSI, which indicates that the service is not urgent, and the requirement of the service on reliability is generally not high, then for the service, a CQI with a higher block error rate or a lower priority of the block error rate may be used.

Alternatively, the content of the CSI indicates the number of antenna ports for which the CSI is intended. If the number of antenna ends targeted by the content of the CSI is large, the service is considered not to be urgent, because the calculation time is long, the CQI with a low block error rate or a low priority of the block error rate may be selected, and if the number of antenna ports targeted by the content of the CSI is large, the calculation time period may be considered to be urgent, and the CQI with a large block error rate or a high priority of the block error rate may be selected.

In a sixth aspect, a communication method is provided that is executable by a communication device, such as a network device, such as a base station. The method comprises the following steps: determining first information, wherein the first information is used for indicating CQI; and sending the first information through Downlink Control Information (DCI).

In one possible design, the first information includes a coding rate of the MCS, the coding rate of the MCS belongs to at least one of a plurality of rate sets, the plurality of rate sets includes a first rate set and a second rate set, a CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the first rate set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the second rate set is a second CQI index.

In one possible design, the first information may include the scheduled transport block size, the scheduled transport block size may belong to one of a plurality of transport block size sets, the plurality of transport block size sets may include a first transport block size set and a second transport block size set, a CQI index corresponding to the CQI corresponding to the scheduled transport block size included in the first transport block size set may be a first CQI index, and a CQI index corresponding to the CQI corresponding to the scheduled transport block size included in the second transport block size set may be a second CQI index.

In one possible design, the first information includes the feedback time interval, the feedback time interval belongs to at least one of a plurality of time interval sets, the plurality of time interval sets includes a first time interval set and a second time interval set, a CQI index corresponding to the CQI corresponding to the feedback time interval included in the first time interval set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the feedback time interval included in the second time interval set is a second CQI index.

In one possible design, the first information includes a detection period of the DCI, the detection period of the DCI belongs to at least one of a plurality of detection period sets, the plurality of detection period sets include a first detection period set and a second detection period set, a CQI index corresponding to the CQI corresponding to the detection period included in the first detection period set is a first CQI index, and a CQI index corresponding to the CQI corresponding to the detection period size included in the second detection period size set is a second CQI index.

For example, the shorter the detection period of the DCI indicates the more urgent the need is, such a service may be the URLLC service, or other more urgent services, and for such a service, the CQI with a lower block error rate or a higher priority of the block error rate may be used to ensure reliability. If the detection period of the DCI is long, which indicates that the requirement is not urgent, and the requirement of the service for reliability is generally not high, then the CQI with a high block error rate or a low priority of the block error rate may be used for the service.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

1) Terminal equipment, including devices that provide voice and/or data connectivity to a user, may include, for example, handheld devices with wireless connection capability or processing devices connected to wireless modems. The terminal device may communicate with a core network via a Radio Access Network (RAN), exchanging voice and/or data with the RAN. The terminal device may include a User Equipment (UE), a wireless terminal device, a mobile terminal device, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an Access Point (AP), a remote terminal device (remote), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), a user equipment (user device), or the like. For example, mobile phones (or so-called "cellular" phones), computers with mobile terminal equipment, portable, pocket, hand-held, computer-included or vehicle-mounted mobile devices, smart wearable devices, and the like may be included. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. Also included are constrained devices, such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Examples of information sensing devices include bar codes, Radio Frequency Identification (RFID), sensors, Global Positioning Systems (GPS), laser scanners, and the like.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

2) A network device, e.g., including a base station (e.g., access point), may refer to a device in an access network that communicates over the air-interface, through one or more cells, with wireless terminal devices. The network device may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB, or eNB, or e-NodeB) in a Long Term Evolution (LTE) system or an evolved LTE system (LTE-Advanced, LTE-a), or may also include a next generation Node B (gNB) in a 5G NR system, which is not limited in the embodiments of the present application.

In addition, in this embodiment of the present application, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell), and the small cell may include: urban cells (Metro cells), Micro cells (Micro cells), Pico cells (Pico cells), Femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services.

In addition, multiple cells can simultaneously work at the same frequency on a carrier in an LTE system or an NR system, and under some special scenarios, the concepts of the carrier and the cell can also be considered to be equivalent. For example, in a Carrier Aggregation (CA) scenario, when a secondary carrier is configured for a UE, a carrier index of the secondary carrier and a Cell identity (Cell ID) of a secondary Cell operating on the secondary carrier are carried at the same time, and in this case, the concepts of the carrier and the Cell may be considered to be equivalent, for example, it is equivalent that the UE accesses one carrier and one Cell.

3) Subcarrier spacing, the value of the spacing between the center positions or peak positions of two subcarriers adjacent in the frequency domain in an Orthogonal Frequency Division Multiplexing (OFDM) system. For example, the subcarrier spacing in a Long Term Evolution (LTE) system is 15 (kilohertz), and the subcarrier spacing in a 5G NR system may be 15kHz, or 30kHz, or 60kHz, or 120kHz, etc.

Reference may be made to table 1 below:

TABLE 1

Where μ is used to indicate the subcarrier spacing, for example, when μ is 0, the subcarrier spacing is 15kHz, and when μ is 1, the subcarrier spacing is 30 kHz.

4) The URLLC service has extremely high requirement on time delay, the one-way transmission time delay from a sending end to a receiving end is required to be within 0.5ms, and the transmission reliability is up to 99.999% within 1 ms.

In order to meet the transmission delay requirement of URLLC traffic, the data transmission of the wireless air interface may use a shorter time scheduling unit, for example, a mini-slot (mini-slot) or a slot with a larger sub-carrier interval as a minimum time scheduling unit. One mini-slot includes one or more time domain symbols, where the time domain symbols may be orthogonal frequency division multiplexing OFDM symbols. For a time slot with a subcarrier interval of 15kHz, the time slot comprises 6 or 7 time domain symbols, and the corresponding time length is 0.5 ms; for a time slot with a subcarrier spacing of 60kHz, the corresponding time length is shortened to 0.125 ms.

The generation of data packets of URLLC traffic is bursty and random, and may not generate data packets for a long time or may generate multiple data packets for a short time. The data packets of URLLC traffic are in most cases small packets, e.g. 50 bytes. The characteristics of the data packets of URLLC traffic can affect the manner in which resources are allocated to the communication system. Resources herein include, but are not limited to: time domain symbols, frequency domain resources, time frequency resources, codeword resources, beam resources, and the like. Generally, the allocation of system resources is performed by the access network device, and the access network device is taken as an example for description below. If the access network device allocates resources for the URLLC service in a resource reservation manner, system resources are wasted when there is no URLLC service. Moreover, the short delay characteristic of URLLC service requires that the data packet is transmitted in a very short time, so the access network device needs to reserve a large enough bandwidth for URLLC service, which results in a serious decrease in the utilization rate of system resources.

URLLC service data usually employs a shorter time scheduling unit to meet the requirement of ultra-short delay, for example, 2 time domain symbols at 15kHz subcarrier intervals are employed, or one time slot at 60kHz subcarrier intervals is employed, corresponding to 7 time domain symbols, and the corresponding time length is 0.125 ms.

5) A CQI table including at least one of a modulation scheme (modulation), a coding rate (coding rate), an efficiency value (efficiency), and a BLER. A CQI table may include at least one CQI (or at least one CQI), each CQI having a corresponding index (i.e., CQI index), and at least one of the following: modulation mode, coding rate, efficiency value and BLER.

The system may support multiple CQI tables, where each CQI table may correspond to one BLER or multiple BLERs. Then the base station and the terminal device determine whether the CQI index of the CQI in the table is reported by the terminal device during the communication process. In the introduction process, the example that the system supports 2 CQI tables is mainly taken as an example, and in practical application, the number of CQI tables is not limited to this.

6) Channel State Information (CSI), in general, CSI is divided into periodic CSI (P-CSI), aperiodic CSI (a-CSI), and semi-persistent CSI (SPS-CSI). The periodic CSI means that the terminal device periodically transmits CSI to the network device, the aperiodic CSI is transmitted once triggered by the network device through Downlink Control Information (DCI), and the semi-persistent CSI transmitting network device triggers the terminal device to continuously transmit CSI for a period of time through the downlink control information. As seen from the sending mechanism, the aperiodic CSI can enable the network device to instruct the terminal device to send the CSI at this time according to its own needs, so as to be more flexible. However, each trigger depends on the sending of the DCI, in order to control the DCI number, the semi-persistent CSI is introduced to reduce the control channel resources occupied by the DCI, and the periodic CSI is configured by the higher layer signaling, which saves the sending of the DCI most, so that all three mechanisms are reserved. It should be noted that, in the fourth generation mobile communication system (4G), only periodic CSI and aperiodic CSI are supported, where the aperiodic CSI is necessarily transmitted in a Physical Uplink Shared Channel (PUSCH), and the periodic CSI is necessarily transmitted in a Physical Uplink Control Channel (PUCCH). While in the current discussion of 5G NR systems, semi-persistent CSI is introduced and it is also agreed that aperiodic CSI can be transmitted in PUCCH. The CSI includes one or more of Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Rank Indicator (RI), Reference Signal Received Power (RSRP), channel-state-Information reference signal resource indicator (CRI), number of non-zero wideband weighting coefficients (indicator of the number of non-zero wideband weighting coefficients), and the like.

7) The bandwidth part (BWP) refers to a part of the channel bandwidth, and may also be called "operating bandwidth" (or transmission bandwidth), and the mini BWP (mini BWP), BWP Unit (BWP Unit), BP sub-band, etc., which may be abbreviated as BWP or BP, and in this embodiment, the name and abbreviation of the bandwidth part are not specifically limited. BWP may be a contiguous segment of resources in the frequency domain. For example, one bandwidth part contains consecutive K (K >0) subcarriers; or, one bandwidth part is a frequency domain resource where N (N >0) non-overlapping continuous Resource Blocks (RBs) are located; or, a bandwidth part is a frequency domain resource where M (M >0) non-overlapping consecutive Resource Block Groups (RBGs) are located, where a RBG includes P (P >0) consecutive RBs. One bandwidth part is associated with one particular system parameter (numerology) that includes at least one of a subcarrier spacing and a Cyclic Prefix (CP).

8) The block error rate, herein abbreviated BLER, does not exclude other translations or other names. BLER is the percentage of the erroneous block out of all the blocks transmitted. For example, BLER may be equal to one of { x × 10e-1, x × 10e-2, x × 10e-3, x × 10e-4, x × 10e-5, x × 10e-6, x × 10e-7, x × 10e-8, x × 10e-9}, or may be equal to other values. Wherein 10e-1 is 10^-1Other values of BLER are similar, as is 0.1. Where x is a positive number, for example, x is 1 or 5, and may also be equal to other values. That is, it is understood that the BLER may also be replaced with a correct rate, which may be equal to one of {1-x 1e-1, 1-x 1e-2, 1-x 1e-3, 1-x 1e-4, 1-x 1e-5, 1-x 1e-6, 1-x 1e-7, 1-x 1e-8, or 1-x 1e-9 }.

9) The higher layer signaling may refer to signaling sent by a higher layer protocol layer, and the higher layer protocol layer is at least one protocol layer above the physical layer. The higher layer protocol layer may specifically include at least one of the following protocol layers: a Medium Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Resource Control (RRC) layer, and a non-access stratum (NAS) layer.

Dynamic signaling may refer to signaling sent by the physical layer, such as signaling or information sent through DCI.

10) As for the waveform, the present document refers to a waveform of DCI, or a waveform of a resource where the second information is located, and the like. At present, a 5G NR system supports two waveforms in uplink, one is OFDM, the other is single carrier frequency division multiple access (SC-FDMA), and the 5G NR system supports OFDM in downlink.

11) A Time Adjustment Group (TAG), a TAG may include one carrier or multiple carriers, or one BWP or multiple BWPs.

12) One PUCCH group may include one TAG or multiple TAGs, and may also include one carrier or multiple carriers.

13) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. The "plurality" means two or more, and in view of this, the "plurality" may also be understood as "at least two" in the embodiments of the present application. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects.

The technical background of the embodiments of the present application is described first, and mainly how to order CSI carried on PUCCH and CSI carried on PUSCH when CSI is currently transmitted.

First is the CSI carried on PUCCH.

1. In the case of not distinguishing CSI part1 from CSI part2, the ordering manner may refer to table 1.

TABLE 1

In table 1, the uplink control information bit sequence is a sequence obtained by sorting CSI reports, where a₀～a_A-1Representing the bits in the sequence, the CSI report number is referred to herein as the index of the CSI report. The same is true for the following descriptions of tables 2-5.

2. In the case of not distinguishing CSI part1 and CSI part2, or in the case of distinguishing CSI part1 and CSIpart2, for CSI part1, the sorting manner may refer to table 2.

TABLE 2

3. In the case of distinguishing CSI part1 from CSI part2, for CSI part2, the ordering manner can refer to table 3.

TABLE 3

If the capacity of the PUCCH is limited, the length of the output sequence needs to be limited, and if the sequence obtained after the sequencing is too long, some information may be discarded from the rear of the sequence, and it can be known from tables 1 to 3 that the information of the CSI report with a larger index number may be discarded at present.

The following is CSI carried on PUSCH, including CSI part1 and CSI part 2.

4. For CSI part1, the ordering can be referred to table 4.

TABLE 4

5. For CSI part2, the ordering can be referred to table 5.

TABLE 5

In addition, see table 6, which is the ordering of the priority (priority) of CSI part 2.

TABLE 6

Where priority 0 is the highest priority, i.e., table 6 is sorted from top to bottom in order of priority. It can be seen that the index of the current CSI report represents the CSI part2 priority of the CSI report.

If the CSI part2 exceeds the code rate, information needs to be dropped according to priority, i.e., information with low priority is dropped. As can be seen from tables 4-6, for CSI part2, which is also sorted from smaller to larger according to the index of the CSI report, the index of the CSI report represents the priority, and similarly, the information of the CSI report with larger index may be discarded.

However, the index of the CSI report cannot represent the reliability of the CSI report, that is, no matter the CSI is carried on the PUCCH or the CSI is carried on the PUSCH, the reliability of the CSI report is not considered at present when the information is discarded, although the index number of the discarded information is larger, the discarded information may belong to the CSI report with higher reliability, such information may be more important, that is, the present sorting manner may cause more important information to be discarded.

In view of this, the technical solution of the embodiment of the present application is provided to minimize the possibility that important information is discarded.

The embodiment of the application can be applied to an LTE system or a 5G NR system, and can also be applied to a next generation mobile communication system or other similar communication systems.

The technical solution provided in the embodiment of the present application may be applied to URLLC services, and certainly is not limited thereto, for example, the technical solution provided in the embodiment of the present application may also be applied to other services having similar requirements to URLLC services.

Then, the configured BLER may not be equal to 0, or may also be equal to 0, and is not limited in particular. If the configured BLER is equal to 0, it may actually correspond to an unconfigured BLER, but unlike the unconfigured BLER, if the BLER is configured and the BLER is equal to 0, it is still considered that there is a correspondence between the CSI report and the BLER, only that the corresponding BLER is 0, and if the BLER is not configured, it is considered that there is no correspondence between the CSI report and the BLER.

Since the uplink control information bit sequence is generated according to the CSI report set (or CSI report), the bits included in the uplink control information bit sequence have a correspondence relationship with the CSI report set (or CSI report), and thus the order of the CSI report sets described as corresponding to the bits in the uplink control information bit sequence in S24 includes the order from the first CSI report set to the second CSI report set.

The terminal device performs measurement to determine a plurality of CSI reports, in this embodiment, the plurality of CSI reports correspond to at least two BLERs, where the at least two BLERs include a first BLER and a second BLER, and may also include other BLERs, for example, a third BLER, a fourth BLER, and so on. Where the CSI report corresponds to BLER, it can be understood that the CSI report is configured with BLER.

Since a plurality of CSI reports correspond to at least two BLERs, the terminal device may divide the determined CSI reports into respective sets of CSI reports, wherein one set of CSI reports corresponds to one BLER, which may be understood as that the CSI reports included in one set of CSI reports all correspond to the same BLER. For example, the terminal device determines at least two CSI report sets, where the at least two CSI report sets include a first CSI report set corresponding to the first BLER and a second CSI report set corresponding to the second BLER, and of course, if the multiple CSI reports also correspond to other BLERs, the terminal device may also obtain other CSI report sets, for example, the at least two BLERs also include a third BLER and a fourth BLER, and the at least two CSI report sets also include a third CSI report set corresponding to the first BLER and a second CSI report set corresponding to the fourth BLER. Wherein each of the at least two CSI report sets comprises at least one CSI report, e.g., a first CSI report set comprises at least one CSI report, a second CSI report set also comprises at least one CSI report, and so on.

In addition, as described herein, the terminal device determines at least two CSI reports, only to distinguish the CSI reports obtained by the terminal device through measurement according to the BLER, in practical application, it is possible that a CSI report set actually exists, that is, after the terminal device obtains the CSI reports through measurement, a corresponding CSI report set may be actually generated, and the CSI reports are put into the corresponding CSI report set, but the CSI report set may not exist, and after the terminal device obtains the CSI reports through measurement, it may only determine the BLER of the obtained CSI reports. That is, the concept of a CSI report set is introduced herein for convenience of introduction only, and does not limit that feature to be necessarily present.

After obtaining the at least two CSI report sets, the terminal device may generate an uplink control information bit sequence according to a mapping ordering rule, where the mapping ordering rule includes an order from the first CSI report set to the second CSI report set, and of course, if there are more CSI report sets, for example, the at least two CSI report sets further include a third CSI report set and a fourth CSI report set, the mapping ordering rule may include an order from the first CSI report set, to the second CSI report set, to the third CSI report set, and then to the fourth CSI report set.

That is to say, the mapping ordering rule is a rule that orders according to the BLER corresponding to the CSI report, and if more CSI report sets are included, the specific mapping ordering rule may be similar.

Wherein the first BLER and the second BLER may satisfy:

the first BLER is less than the second BLER, e.g., the first BLER is 10e-5 and the second BLER is 10 e-3; or the like, or, alternatively,

the first BLER has a higher priority than the second BLER.

Alternatively, if the third BLER and the fourth BLER are further included, the first BLER, the second BLER, the third BLER, and the fourth BLER may satisfy:

first BLER < second BLER < third BLER < fourth BLER, e.g., the first BLER is 10e-5, the second BLER is 10e-4, the third BLER is 10e-3, the fourth BLER is 10 e-2; or the like, or, alternatively,

the priority of the first BLER > the priority of the second BLER > the priority of the third BLER > the priority of the fourth BLER.

Alternatively, the first BLER and the second BLER may satisfy:

the first BLER is greater than the second BLER, e.g., the first BLER is 10e-3 and the second BLER is 10 e-5; or the like, or, alternatively,

the first BLER has a lower priority than the second BLER.

the first BLER > the second BLER > the third BLER > the fourth BLER, e.g., the first BLER is 10e-2, the second BLER is 10e-3, the third BLER is 10e-4, the fourth BLER is 10 e-5; or the like, or, alternatively,

the priority of the first BLER < the priority of the second BLER < the priority of the third BLER < the priority of the fourth BLER.

In the following description, if it is exemplified that the at least two BLERs comprise the first BLER and the second BLER, the first BLER is less than the second BLER, or the priority of the first BLER is higher than the priority of the second BLER, and if it is exemplified that the at least two BLERs comprise the first BLER, the second BLER, the third BLER, and the fourth BLER, the first BLER < the second BLER < the third BLER < the fourth BLER, or the priority of the first BLER > the priority of the second BLER > the priority of the third BLER > the priority of the fourth BLER. However, the embodiment of the present application does not limit the size relationship between the BLERs in the at least two BLERs, nor the priority of the BLERs in the at least two BLERs.

In addition, the relation between the BLER value and the BLER priority is not limited herein. For example, one possibility is that the smaller the BLER value is, the higher the priority of the BLER value of 10e-5 is, the higher the priority of the BLER value of 10e-3 is, or the larger the BLER value is, the higher the priority of the BLER value of 10e-3 is, the higher the priority of the BLER value of 10e-5 is.

Taking the example that the at least two BLERs include the first BLER and the second BLER, if the first BLER is less than the second BLER, or the priority of the first BLER is higher than the priority of the second BLER, the mapping ordering rule is ordering according to the order of the values of the BLERs from small to large, or ordering according to the priority of the BLERs from high to low, and it can be considered that the ordering according to the order of the values of the BLERs from small to large is one of the cases of ordering according to the priority of the BLERs from high to low.

In addition, the priority of the above BLER is predefined. There is also a case where the priority of BLER is indicated by the network equipment through higher layer signaling or dynamic signaling, where the dynamic signaling may be indicated through DCI.

In the embodiment of the present application, the uplink control information bit sequence generated according to the mapping ordering rule includes, but is not limited to, the following cases:

case 1, in the uplink control information bit sequence, the mapping position of the CSI report included in the first CSI report set is above the mapping position of the CSI report included in the second CSI report set.

Case 2, in the uplink control information bit sequence, the mapping position of the wideband CSI and/or the subband CSI of the CSI report included in the first CSI report set is above the mapping position of the wideband CSI and/or the subband CSI of the CSI report included in the second CSI report set.

Case 3, in the uplink control information bit sequence, at least two items of the following are included:

the first CSI report set includes a mapping position of wideband CSI for CSI reports that is above a mapping position of wideband CSI for CSI reports that is included in the second CSI report set, and,

the second CSI report set includes a mapping position of wideband CSI of CSI reports on top of a mapping position of sub-band CSI of CSI reports included in the first CSI report set, and,

the mapping position of the sub-band CSI of the CSI report included in the first CSI report set is above the mapping position of the sub-band CSI of the CSI report included in the second CSI report set.

The upper part of the mapping position may be understood as that the bit sequence number of the mapping of the CSI report located at the upper part is smaller than the bit sequence number of the mapping of the CSI report located at the lower part.

In case 2 or case 3, the wideband CSI may include wideband CSI part1 and/or wideband CSI part2, and correspondingly, the subband CSI may include subband CSI part1 and/or subband CSI part2, and may further include subband CSI of even subbands and/or subband CSI of odd subbands.

For case 3, the uplink control information bit sequence includes at least two entries because it is considered that some CSI reports may include only wideband CSI or only subband CSI, considering that the CSI report may include both wideband CSI and subband CSI. For example, the CSI reports included in the first CSI report set include wideband CSI and subband CSI, and the CSI reports included in the second CSI report set also include wideband CSI and subband CSI, the generated uplink control information bit sequence may include 3 items shown in case 3, or the 1 st and 3 rd items shown in case 3, or the first CSI report set includes CSI reports including wideband CSI and sub-band CSI, the second CSI report set includes CSI reports including sub-band CSI only, the generated uplink control information bit sequence may include items 2 and 3 as shown in case 3, or the CSI reports included in the first CSI report set comprise wideband CSI, the CSI reports included in the second CSI report set comprise wideband CSI and sub-band CSI, the generated uplink control information bit sequence may include items 1 and 2 shown in case 3, and so on.

Wherein case 3 can be implemented by: the terminal equipment sorts the wideband CSI of the CSI reports included in the first CSI report set and the wideband CSI of the CSI reports included in the second CSI report set according to the mapping sorting rule, and sorts the sub-band CSI of the CSI reports included in the first CSI report set and the sub-band CSI of the CSI reports included in the second CSI report set according to the mapping sorting rule, wherein the sorted wideband CSI is positioned in front of the sorted sub-band CSI.

Next, how the terminal device obtains the uplink control information bit sequence will be described, and the uplink control information bit sequence to be described below will correspond to case 1, case 2, or case 3 as described above.

In at least one CSI report included in the CSI reports measured by the terminal device, CSIpart1 and CSI part2 may not be distinguished, or CSI part1 and/or CSI part2 may also be included, so the uplink control information bit sequence generated according to the mapping ordering rule is described in the following cases. In the following description, the mapping ordering rule is mainly ordered according to the BLER value from small to large, or the mapping ordering rule is ordered according to the BLER priority from high to low, and the BLER priority with low value is high. For ease of understanding, a tabular presentation is introduced below.

G. In at least one CSI report included in a plurality of CSI reports obtained by terminal equipment measurement, CSIdart 1 and CSI part2 are not distinguished, or CSI part1 and CSI part2 are distinguished, and CSI part1 is included.

Since CSI may be carried on PUCCH and PUSCH, the following description is divided into the PUCCH case and the PUSCH case.

G1, carrying the uplink control information bit sequence on PUCCH.

First, in at least one CSI report included in the plurality of CSI reports measured by the terminal device, the CSIpart1 and the CSI part2 are not distinguished, please refer to table 7.

TABLE 7

In table 7, A, B, C, D, E, F each indicate the index of the CSI report, for example, the smallest BLER corresponds to the CSI report from index a to index B, the second smallest BLER corresponds to the CSI report from index C to index D, and the largest BLER corresponds to the CSI report from index E to index F. Wherein, 1< ═ A < ═ B < ═ n, 1< ═ C < ═ D < ═ n, and 1< ═ E < ═ F < ═ n. Optionally, a, B, C, D, E, F are different from each other. And n is the maximum value of the indexes of the CSI reports measured by the terminal equipment. In the tables to be described later, similar to table 7, the description is omitted.

In table 7, the CSI reports may be arranged in the order of the values of the index numbers from small to large or in other manners, and if the CSI reports from the index number a to the index number B do not include CSI reports of other index numbers, the CSI reports a and the CSI reports B may be arranged in the order of the values of the index numbers from small to large or in other manners; in table 7, the CSI reports may be arranged in the order of the values of the index numbers from small to large or in other manners, and if the CSI reports from the index number C to the index number D do not include CSI reports of other index numbers, the CSI reports C and the CSI reports D may be arranged in the order of the values of the index numbers from small to large or in other manners; in table 7, the CSI reports may be arranged in the order from the smaller to the larger of the values of the index numbers, or may be arranged in other manners, and if the CSI reports from the index number E to the index number F do not include the CSI reports of other index numbers, the CSI reports E and the CSI reports F may be arranged in the order from the smaller to the larger of the values of the index numbers, or may be arranged in other manners.

In addition, if the number of BLERs corresponding to the CSI report measured by the terminal device is 3, the ellipses included in the CSI report number of table 7 may be ignored, if the number of BLERs corresponding to the CSI report measured by the terminal device is 2, the entry corresponding to the CSI report from index C to index D and the ellipses may be removed from table 7, and if the number of BLERs corresponding to the CSI report measured by the terminal device is greater than or equal to 4, the CSI reports corresponding to other BLERs may be placed in the ellipses part in the order of BLER from low to high.

For example, the BLERs corresponding to the CSI report measured by the terminal device include a first BLER, a second BLER, a third BLER, and a fourth BLER, the minimum BLER in table 7 is for example the first BLER, the CSI reports from CSI report a to CSI report B belong to the first CSI report set (comprising CSI report a and CSI report B), the next smaller BLER in table 7 is for example the second BLER, the CSI reports from CSI report C to CSI report D belong to the second CSI report set (comprising CSI report C and CSI report D), the largest BLER in table 7 is for example the fourth BLER, the CSI reports from CSI report E to CSI report F belong to a fourth CSI report set (including CSI report E and CSI report F), then, in table 7, the third BLER is included between the second BLER and the fourth BLER, the CSI report corresponding to the third BLER, i.e., the CSI report included in the third CSI report set, may be placed in the ellipsis part.

For example, a CSI report from CSI report a to CSI report B belongs to a first CSI report set, and a CSI report from CSI report C to CSI report D belongs to a second CSI report set, it can be seen that, because the BLER corresponding to the first CSI report set is smaller than the BLER corresponding to the second BLER, or because the BLER value is smaller, the priority is higher, or the network device configures, through high-layer signaling or dynamic signaling, that the BLER priority corresponding to the first CSI report set is higher, the priority of the BLER corresponding to the first CSI report set is higher than the priority of the BLER corresponding to the second BLER, and in the uplink control information bit sequence shown in table 2, the mapping position of the CSI report included in the first CSI report set is above the mapping position of the CSI report included in the second CSI report set, which is in accordance with case 1. It may also be understood that the CSI reports comprised by the first CSI report set are ranked before the CSI reports comprised by the second CSI report set, or that the index of the CSI reports comprised by the first CSI report set is smaller than the index of the CSI reports comprised by the second CSI report set.

Next, in at least one CSI report included in the plurality of CSI reports measured by the terminal device, the CSI part1 and the CSI part2 are not distinguished, or, in at least one CSI report included in the plurality of CSI reports measured by the terminal device, the CSI part1 and the CSI part2 are distinguished and the CSI part1 is included, please refer to table 8.

TABLE 8

For example, a CSI report from CSI report a to CSI report B belongs to a first CSI report set, and a CSI report from CSI report C to CSI report D belongs to a second CSI report set, it can be seen that, because the BLER corresponding to the first CSI report set is smaller than the BLER corresponding to the second BLER, or because the BLER value is smaller, the priority is higher, or the network device configures, through higher layer signaling or dynamic signaling, that the BLER priority corresponding to the first CSI report set is higher, and the priority of the BLER corresponding to the first CSI report set is higher than the priority of the BLER corresponding to the second BLER, in the uplink control information bit sequence shown in table 8, the mapping position of the CSI report included in the first CSI report set is on top of the mapping position of the CSI report included in the second CSI report set, or the mapping position of the CSI part1 of the CSI report included in the first CSI report set is on top of the mapping position of the CSI part1 of the CSI report included in the second CSI report set, are consistent with case 1. It may also be understood that the CSI report comprised by the first CSI report set is ranked before the CSI report comprised by the second CSI report set, or that the CSI part1 of the CSI report comprised by the first CSI report set is ranked before the CSIpart1 of the CSI report comprised by the second CSI report set.

The remaining corresponding descriptions may be referred to as previously described for table 7.

G2, and the uplink control information bit sequence carried on the PUSCH.

In at least one CSI report included in the plurality of CSI reports measured by the terminal device, CSI part1 and CSIpart2 are distinguished, but only CSI part1 is included, please refer to table 9.

TABLE 9

For example, a CSI report from CSI report a to CSI report B belongs to a first CSI report set, and a CSI report from CSI report C to CSI report D belongs to a second CSI report set, it can be seen that, because the BLER corresponding to the first CSI report set is smaller than the BLER corresponding to the second BLER, or because the BLER value is smaller, the priority is higher, or the network device configures, through higher layer signaling or dynamic signaling, that the BLER priority corresponding to the first CSI report set is higher, the priority of the BLER corresponding to the first CSI report set is higher than the priority of the BLER corresponding to the second BLER, so that, in the uplink control information bit sequence shown in table 9, the mapping position of the CSI part1 of the CSI report included in the first CSI report set is above the mapping position of the CSI part1 of the CSI report included in the second CSI report set, and is consistent with case 1. It can also be understood that the CSI part1 of the CSI report comprised by the first CSI report set is ranked before the CSI part1 of the CSI report comprised by the second CSI report set.

As described above, the mode G preferentially ensures that CSI reports with low BLER or CSI reports with higher BLER priority are ranked ahead and discarded as far as possible. And the mode G has small modification to the sequencing of the existing CSI reports and is easier to adapt to the existing protocol.

H. In at least one CSI report included in a plurality of CSI reports obtained by terminal equipment measurement, CSIdart 1 and CSI part2 are distinguished, and CSI part2 is included.

Also, since CSI may be carried on PUCCH and PUSCH, the following description is also divided into the PUCCH case and the PUSCH case.

H1, and the uplink control information bit sequence carried on the PUCCH.

Two possibilities are presented below.

See table 10 for possibility 1.

Watch 10

For example, CSI reports from CSI report a to CSI report B belong to a first CSI report set, CSI reports from CSI report C to CSI report D belong to a second CSI report set, and it can be seen that, since the BLER for the first CSI report set is smaller than the BLER for the second BLER, or, because the smaller the BLER value is, the higher the priority is, or the network device configures the higher the BLER priority corresponding to the first CSI report set through high-level signaling or dynamic signaling, the BLER for the first CSI report set has a higher priority than the BLER for the second BLER, then in the sequence of uplink control information bits shown in table 10, the mapping positions of the wideband CSI part2 and the sub-band CSI part2 of CSI reports included in the first CSI report set are above the mapping positions of the wideband CSI part2 and the sub-band CSI part2 of CSI reports included in the second CSI report set, which is in accordance with case 2. It may also be understood that the wideband CSI part2 and the sub-band CSI part2 of CSI reports comprised by the first CSI report set are ranked before the wideband CSI part2 and the sub-band CSI part2 of CSI reports comprised by the second CSI report set.

Possibility 2, see table 11.

TABLE 11

For example, a CSI report from CSI report a to CSI report B belongs to a first CSI report set, a CSI report from CSI report C to CSI report D belongs to a second CSI report set, and a CSI report from CSI report E to CSI report F belongs to a third CSI report set, it can be seen that, because the BLER corresponding to the first CSI report set < the BLER corresponding to the second BLER < the BLER corresponding to the third CSI report set, or the BLER value is smaller, the priority is higher, or the network device configures, through high-layer signaling or dynamic signaling, the BLER priority corresponding to the first CSI report set is the highest and/or the sum of BLER priority corresponding to the second CSI report set and/or the BLER priority corresponding to the third CSI report set is the lowest, then the priority of the BLER corresponding to the first CSI report set > the priority of the BLER corresponding to the second BLER > the priority of the third BLER, then in the uplink control information bit sequence shown in table 11, the order of arrangement of the wideband CSI part2 is that the mapping position of the wideband CSI part2 of CSI reports included in the first CSI report set > the mapping position of the wideband CSIpart2 of CSI reports included in the second CSI report set > the mapping position of the wideband CSI part2 of CSI reports included in the third CSI report set, the order of arrangement of the subband CSIpart2 is that the mapping position of the subband CSI part2 of CSI reports included in the first CSI report set > the mapping position of the subband CSI part2 of CSI reports included in the second CSI report set > the mapping position of the subband CSI part2 of CSI reports included in the third CSI report set, and the wideband CSI part2 of CSI reports included in the third CSI report set is located above the subband CSIpart2 of CSI reports included in the first CSI report set, wherein the mapping position of the CSI report wideband CSI part2 of "of the first CSI report set includes the mapping position of CSI reports > the mapping position of the CSI part2 of CSI reports included in the second CSI report set", the mapping position of the wideband CSI part2 representing the CSI report included in the first CSI report set is above the mapping position of the wideband CSI part2 representing the CSI report included in the second CSI report set, and the other expressions are similar. It can be seen that table 11 corresponds to case 3.

H2, and the uplink control information bit sequence carried on the PUSCH.

Two possibilities are presented below.

Possibility 3, see table 12.

TABLE 12

Table 12 is similar to table 10, and table 10 can be referred to for the description of table 12, and will not be described in detail.

Specifically, under the possibility 3, the embodiment of the present application may also define the priority of the CSI part2, please refer to table 13.

Watch 13

Wherein, the priority 0 is the highest priority, the priority 2N_REPIs the lowest priority. In table 13, the wideband CSI part2 of the CSI reports a to B of priority 0 is arranged first, the subband CSI part2 of the even subband of the CSI reports a to B of priority 0 is arranged, the subband CSI part2 of the odd subband of the CSI reports a to B of priority 0 is arranged, the wideband CSI part2 of the CSI reports C to D of priority 1 is arranged next, the subband CSI part2 of the even subband of the CSI reports C to D of priority 1 is arranged next, the subband CSI part2 of the odd subband of the CSI reports C to D of priority 1 is arranged next, and so on.

From the CSI report with index a to the CSI report with index B, CSI reports with other indexes may be included, or CSI reports with other indexes may not be included, if the CSI reports from index a to index B also include CSI reports with other indexes, these CSI reports also correspond to the minimum BLER, in table 7, these CSI reports may be arranged in order of the indexes from small to large, for example, a is smaller than B, and there is no CSI with other indexes between a and B, the wideband CSI part2 of CSI report a is arranged first, the subband csipt 2 of the even subband of CSI report a is arranged next, the CSI part2 of the odd subband of CSI report a is arranged next, the wideband CSI part2 of the CSI reports C to D of priority 1 is arranged next, and the CSI part2 of the even subband of CSI report B is arranged next, the sub-band CSI part2 of the odd sub-band of CSI report B is rearranged, or may be arranged in other manners; from the CSI report with index C to the CSI report with index D, CSI reports with other index may be included, or CSI reports with other index may not be included, if the CSI reports from index C to index D also include CSI reports with other index, these CSI reports also correspond to the next-smallest BLER, and in table 5, these CSI reports may be arranged in order of the values of the index from small to large, or may be arranged in other manners; from the CSI report with index E to the CSI report with index F, CSI reports with other index may be included, or CSI reports with other index may not be included, and if the CSI reports from index E to index F also include CSI reports with other index, these CSI reports also correspond to the largest BLER, and in table 5, these CSI reports may be arranged in order of the values of the index from small to large, or may be arranged in other manners.

Possibility 4, see table 14.

TABLE 14

Table 14 is similar to table 11, and table 11 can be referred to for the description of table 14, and will not be described in detail. That is, table 14 also corresponds to case 3.

Specifically, under possibility 4, the embodiment of the present application may also define the priority of the CSI part2, please refer to table 15.

Watch 15

Wherein, the priority 0 is the highest priority, the priority 2N_REPIs the lowest priority. In Table 10, the priority 0 CSI reports A-B wideband CSI part2 is arranged first, the priority 1 CSI reports A-B wideband CSI part2 is arranged second, and so on until the priority 2N_REPThe wideband CSI part2 of the CSI reports E-F are arranged, then the sub-band CSI part2 of the even sub-band of the CSI reports A-B with the priority 0 is arranged, the sub-band CSI part2 of the odd sub-band of the CSI reports A-B with the priority 0 is arranged, the sub-band CSI part2 of the even sub-band of the CSI reports C-D with the priority 1 is arranged, the sub-band CSI part2 of the odd sub-band of the CSI reports C-D with the priority 1 is arranged, and the like until the priority 2N is arranged_REPThe odd subbands of the CSI reports E to F have their sub-bands CSI part2 aligned.

In tables 7 to 15, the minimum BLER is 10e-5, the next-smallest BLER is 10e-3, and the maximum BLER is 10e-1, which are only examples and are not limited to the actual situation, and in practical applications, the BLER corresponding to the CSI report may be other values, for example, the minimum BLER may be 10 e-6. For another example, the network device configures the correspondence between the BLER and the priority through high-layer signaling or dynamic signaling.

As described above in possibility 1 or possibility 3 under H1, the CSI report with the corresponding BLER being low is ranked ahead, or the CSI report with the corresponding BLER being high in priority is ranked ahead, so as to ensure that the information of the CSI report with high reliability can be retained as much as possible.

As introduced above for possibility 2 or possibility 4 under H1, the order of the existing wideband CSI and sub-band CSI is preserved, the table in the existing protocol is less modified, and it is easier to adapt to the existing protocol.

The mapping ordering rule of the embodiment of the application may include at least one of the tables in tables 7 to 15, so that the terminal device may continue to measure in the current manner to obtain the CSI report, and may order the obtained CSI report according to the mapping ordering rule.

An embodiment is described below, in which the first CSI report set and the second CSI report set include at least one of:

the first CSI report set comprises CSI reports with report indexes smaller than those of the second CSI report set;

the CSI reports included in the first CSI report set comprise wideband CSI, and/or the CSI reports included in the second CSI report set comprise sub-band CSI;

the first CSI report set comprises CSI reports comprising CSI part1, and/or the second CSI report set comprises CSI reports comprising CSI part 2; and the combination of (a) and (b),

the CSI report included in the first CSI report set is carried on a PUCCH, and/or the CSI report included in the second CSI report set is carried on a PUSCH.

The CSI report index included in the first CSI report set is smaller than the CSI report index included in the second CSI report set, and it can be understood that the CSI report index corresponding to the first block error rate is smaller than the CSI report index corresponding to the second block error rate. Optionally, the report index of the CSI report corresponding to the first BLER configured by the network device is definitely smaller than the report index of the CSI report corresponding to the first BLER configured by the network device.

Wherein the CSI reports comprised by the first CSI report set comprise wideband CSI and/or the CSI reports comprised by the second CSI report set comprise subband CSI, it is understood that the first BLER corresponds to CSI reports comprising wideband CSI and the second BLER corresponds to CSI reports comprising subband CSI. Optionally, the CSI reports included in the first CSI report set only include wideband CSI, and the CSI reports included in the first CSI report set may include wideband CSI and subband CSI, or only include subband CSI.

Wherein the CSI reports comprised by the first CSI report set comprise CSI part1, and/or the CSI reports comprised by the second CSI report set comprise CSI part2, it is understood that the first BLER corresponds to CSI reports comprising CSI part1 and the second BLER corresponds to CSI reports comprising CSI part 2. Optionally, the CSI report included in the first CSI report set only includes CSI part1, and the CSI report included in the first CSI report set may include CSI part1 and CSI part2, or only include CSI part 2.

Wherein, the CSI report included in the first CSI report set is carried on PUCCH, and/or the CSI report included in the second CSI report set is carried on PUSCH, it can be understood that the first BLER corresponds to the CSI report carried on PUCCH, and the second BLER corresponds to the CSI report carried on PUSCH. Optionally, the CSI report corresponding to the first BLER is transmitted only on PUCCH, and the CSI report corresponding to the second BLER is transmitted only on PUSCH.

Take the first BLER less than the second BLER, or the first BLER has a higher priority than the second BLER, as an example.

According to the scheme described above, as the BLER is smaller or the priority of the BLER is higher, the mapping position of the corresponding CSI report is higher, and then in the measurement, a smaller report index may be assigned to the CSI report with the smaller BLER or the higher priority of the BLER.

As can be seen from the above-described scheme, generally, the mapping position of the wideband CSI is above the mapping position of the sub-band CSI, and then the CSI report containing the wideband CSI may be assigned with a smaller BLER or a BLER with higher priority, while the CSI report containing the sub-band CSI may be assigned with a larger BLER or a BLER with lower priority. The wideband CSI here may include wideband CSI part1 and/or wideband CSI part2, and similarly, the sub-band CSI may include sub-band CSI part1 and/or sub-band CSI part 2.

As can be seen from the above-described scheme, generally, the CSI part1 is higher in priority than the CSI part2, so that the CSI report containing CSI part1 may be assigned a smaller BLER or a higher BLER in priority, and the CSI report containing CSI part1 may be assigned a larger BLER or a lower BLER in priority.

In addition, the CSI carried on PUCCH is generally higher in priority than the CSI carried on PUSCH, and thus, the CSI report carried on PUCCH may be given a smaller BLER or a higher-priority BLER, while the CSI report carried on PUSCH is given a larger BLER or a lower-priority BLER.

In this embodiment, the terminal device has already processed according to BLER when obtaining the CSI report through measurement, and may directly sort when sorting according to the mapping sorting rule. This embodiment may ensure that the CSI report of the important target BLER is protected without modifying the definitions of the existing protocols.

In the foregoing description, the at least two CSI report sets include a first CSI report set corresponding to the first BLER and a second CSI report set corresponding to the second BLER. It may further be the case that the at least two CSI report sets comprise a third CSI report set, the third CSI report set having no corresponding BLER, for which it may be understood that the third CSI report set is not configured with a BLER. For example, the at least two CSI report sets may include at least one CSI report set configured with BLER and may further include at least one CSI report set not configured with BLER, for example, the at least two CSI report sets include a first CSI report set, a second CSI report set, and a third CSI report set (without limitation, other CSI report sets are also included), or the at least two CSI report sets include the first CSI report set or the second CSI report set, and the third CSI report set, and so on.

For the CSI reports included in the CSI report set not configured with BLER, the CSI reports included in the CSI report set configured with BLER may be located last in the uplink control information bit sequence, for example, in the uplink control information bit sequence, the CSI reports included in the CSI report set configured with BLER may be sorted according to BLER first, after the sorting is completed, the CSI reports included in the CSI report set not configured with BLER may be placed, and if there are a plurality of CSI report sets not configured with BLER, the CSI reports included in the CSI report set not configured with BLER may be sorted during the sorting according to the report index of the CSI reports included in the CSI report set not configured with BLER, or may be sorted randomly. As to how to sort the CSI reports included in the CSI report set configured with BLER according to BLER, reference may be made to the foregoing description.

Taking the example that the at least two CSI report sets include a first CSI report set and a third CSI report set, the first CSI report set corresponds to a first BLER, and the third CSI report set does not correspond to a BLER. Specifically, when the uplink control information bit sequence is generated, the third CSI report set may be regarded as the second CSI report set, for example, when the at least two CSI report sets include the first CSI report set and the second CSI report set, the mapping ordering rule includes an order from the first CSI report set to the third CSI report set, and in the same way, when the at least two CSI report sets include the first CSI report set and the third CSI report set, the mapping ordering rule may include an order from the first CSI report set to the third CSI report set. That is to say, for the CSI report set not configured with BLER, when generating the uplink control information bit sequence, it may be treated as the CSI report set with the largest BLER or the lowest BLER priority, which is, of course, sorted in the order from small to large BLER or in the order from high to low BLER priority, and if sorted in the order from large to small BLER or in the order from low to high BLER priority, for the CSI report set not configured with BLER, when generating the uplink control information bit sequence, it may be treated as the CSI report set with the smallest BLER or the highest BLER priority.

By the scheme provided by the embodiment of the application, the CSI report with low BLER or the CSI report with high BLER priority is arranged in front as much as possible, so that the transmission performance and the time delay can be ensured as much as possible, and if the CSI report is carried on a PUCCH, the high-reliability CQI can be ensured not to be knocked out when the capacity is limited.

In the embodiment shown in fig. 2, one CSI report corresponds to one BLER, so the ordering between the CSI reports is mainly introduced. For a CSI report, the corresponding ordering is actually involved. The order of information included in the CSI report in the related art is first described below.

TABLE 23

At present, one CSI report only corresponds to one BLER, and therefore, as can be seen from tables 16 to 23, the BLER is not naturally considered when mapping one CSI report at present. In this case, the embodiment further provides that, when mapping one CSI report, the CSI report may be sorted according to the BLERs. Specifically, the following examples are given for the purpose of illustration.

An embodiment is described further below by which a second communication method is provided, in which one CSI report may correspond to at least two BLERs. Please refer to fig. 3. In the following description, the method is applied to the application scenario shown in fig. 1 as an example. The flow of the method is described below.

S31, the terminal equipment determines a CSI report, wherein the CSI report comprises CSI part1 and/or CSI part2, and the CSI report at least corresponds to a first block error rate and a second block error rate;

s32, the terminal equipment sends the CSI report, and the network equipment receives the CSI report;

s33, the network equipment determines the CSI part1 and/or the CSI part2 through the CSI report.

In the embodiment of the present application, the CSI report corresponds to at least two BLERs, where the at least two BLERs include a first BLER and a second BLER, and then, under the condition that it is ensured that the content included in the CSI report corresponds to at least two BLERs, the CSI report may be sorted according to the BLERs, and it may be considered that the CSI report determined in S31 is the CSI report sorted according to the method provided in the embodiment of the present application.

The CSI report may include CSI part1 and/or CSI part2, and the following describes the content that the CSI report may include. In the following description, the first CQI and the second CQI correspond to the first BLER and the third CQI and the fourth CQI correspond to the second BLER are taken as examples, and the first CQI and the fourth CQI are CQIs of a first transport block and the second CQI and the third CQI are CQIs of a second transport block, and/or the first CQI and the fourth CQI are wideband CQIs and the second CQI and the third CQI are subband CQIs are taken as examples. In addition, in the following description, mainly taking the CSI report corresponding to 2 BLERs as an example, that is, the first BLER and the second BLER, it is to be understood that when the number of BLERs corresponding to the CSI report is greater than 2, the method is also similar.

As a first example, the CSI report comprises CSI part1 and CSI part2, CSI part1 and CSI part2 comprising at least one of:

the CSI part1 includes a first CQI and/or a second CQI, and the CSI part2 includes a third CQI and/or a fourth CQI;

the CSI part1 includes a third CQI and/or a fourth CQI, and the CSI part2 includes a first CQI and/or a second CQI.

For example, the CSI part1 includes a first CQI, the CSI part2 includes a third CQI, the first CQI corresponds to a first BLER, the third CQI corresponds to a second BLER, and the CSI report corresponds to the first BLER and the second BLER.

In addition, in the first item as above, the CSI part1 includes the first CQI and/or the second CQI, and it is not limited that the CSIpart1 cannot include other CQIs other than the first CQI and the second CQI, nor that the CSI part2 cannot include other CQIs other than the third CQI and the fourth CQI. For example, the CSI part1 includes only the first CQI and not the second CQI, and the CSI part2 may include the second CQI in addition to the third CQI and/or the fourth CQI. Or for example, the CSIpart2 includes only the fourth CQI and not the third CQI, it is possible that the CSI part2 includes the third CQI in addition to the first CQI and/or the second CQI. The same is true for the second term above.

Thus, in a first example, CSI reporting includes several possibilities:

the possibility a, CSI part1 corresponds to one BLER, CSI part2 corresponds to another BLER, e.g. CSIpart1 corresponds to a first BLER, CSI part2 corresponds to a second BLER, or CSI part1 corresponds to a second BLER, CSIpart2 corresponds to a first BLER.

For example, the CSI part1 includes a first CQI and a second CQI, the CSI part2 includes a third CQI, or the CSIpart1 includes a first CQI, the CSI part2 includes a fourth CQI, and so on.

The likelihood b, CSI part1 corresponds to at least two BLERs, CSI part2 corresponds to at least one BLER, e.g. CSI part1 corresponds to a first BLER and a second BLER, CSI part2 corresponds to the first BLER and/or the second BLER.

For example, the CSI part1 includes a first CQI and a fourth CQI, the CSI part2 includes a third CQI, or the CSIpart1 includes a first CQI and a third CQI, the CSI part1 includes a fourth CQI, and so on.

The likelihood c, CSI part2 corresponds to at least two BLERs, CSI part1 corresponds to at least one BLER, e.g. CSIpart1 corresponds to a first BLER and a second BLER, CSI part2 corresponds to the first BLER and/or the second BLER.

For example, the CSI part1 includes a first CQI and the CSI part2 includes a second CQI and a third CQI, or the CSIpart1 includes a second CQI, the CSI part1 includes a first CQI and a fourth CQI, and so on.

The likelihood d, CSI part1 corresponds to at least two BLERs, CSI part2 also corresponds to two BLERs, e.g. CSIpart1 corresponds to a first BLER and a second BLER, CSI part2 also corresponds to a first BLER and a second BLER. For example, CSIpart1 includes a first CQI and a fourth CQI, CSI part2 includes a second CQI and a third CQI, or CSI part1 includes a second CQI and a third CQI, CSI part2 includes a first CQI and a fourth CQI, or CSI part1 includes a first CQI and a third CQI, CSI part2 includes a second CQI and a fourth CQI, and so on.

It can be seen that in the first example, it is contemplated that the CSI report includes CSI part1 and CSI part2, that both CSI part1 and CSI part2 include CQIs, and that the CSI report corresponds to all implementations of at least two BLERs.

In the first example, the order of the CQIs in the CSI report may not be limited, for example, the order of the CQIs in the CSI report may be random, or may be ordered according to at least one of the following rules:

sorting according to BLER corresponding to CQI;

ordered in order from wideband CQI to sub-band CQI.

For example, the CQI with a corresponding smaller BLER or the CQI with a higher priority of the corresponding BLER is placed in CSIpart1, and the CQI with a corresponding larger BLER or the CQI with a lower priority of the corresponding BLER is placed in CSI part2, it can be understood that CSI part1 includes the CQI with a corresponding smaller BLER or the CQI with a higher priority of the corresponding BLER, and CSI part2 includes the CQI with a corresponding larger BLER or the CQI with a lower priority of the corresponding BLER. Since the priority of the CSI part1 is generally higher than that of the CSI part2, placing more reliable information in the CSIpart1 can improve the probability of successful transmission of more reliable information.

For example, the first BLER is less than the second BLER, or the first BLER has a higher priority than the second BLER, then the CQI corresponding to the first BLER may be placed in CSI part1, and the CQI corresponding to the second BLER may be placed in CSIpart2, e.g., the CSI report includes the first CQI, the second CQI, and the third CQI, then the first CQI and the second CQI are placed in CSI part1, and the third CQI is placed in CSI part 2.

Or for example, the CQI corresponding to the first transport block is placed in CSI part1, and the CQI corresponding to the second transport block is placed in CSI part2, it can also be understood that CSI part1 includes the CQI corresponding to the first transport block, and CSI part2 includes the CQI corresponding to the second transport block. Since the priority of the first transport block is generally higher than that of the second transport block, and the priority of the CSI part1 is generally higher than that of the CSI part2, this approach can improve the probability of successful transmission of information corresponding to the first transport block.

For example, the CSI report includes a first CQI, a second CQI, and a third CQI, the first CQI is placed in CSI part1, and the second CQI and the third CQI are placed in CSI part 2.

Or for example, the wideband CQI is placed in CSI part1 and the sub-band CQI is placed in CSI part2, it can also be understood that CSI part1 includes wideband CQI and CSI part2 includes sub-band CQI. This approach may improve the probability of success for wideband CQI transmission, since the priority of wideband CQI is generally higher than the priority of sub-band CQI, while the priority of CSI part1 is generally higher than the priority of CSI part 2.

Of course, any two of the above ordering manners may be combined, for example, the CQI with a corresponding smaller BLER or the corresponding BLER with a higher priority and the CQI corresponding to the first transport block may be placed in the CSI part1, the CQI with a corresponding larger BLER or the corresponding BLER with a lower priority and the CQI corresponding to the second transport block may be placed in the CSI part2, and it is also understood that the CSI part1 includes the CQI with a corresponding smaller BLER or the corresponding BLER with a higher priority and the CQI corresponding to the first transport block and the CSI part2 includes the CQI with a corresponding larger BLER or the corresponding BLER with a lower priority and the CQI corresponding to the second transport block.

For example, the first BLER may be less than the second BLER, or the first BLER may have a higher priority than the second BLER, and the CSI report may include the first CQI, the second CQI, and the third CQI, and the first CQI may be placed in CSI part1, and the second CQI and the third CQI may be placed in CSI part 2.

Of course, the embodiment of the present application is not limited to this, for example, a CQI with a larger BLER or a CQI with a lower priority of the corresponding BLER may be placed in CSI part1, and a CQI with a smaller BLER or a CQI with a higher priority of the corresponding BLER may be placed in CSI part2, that is, CSI part2 includes a CQI with a smaller BLER or a CQI with a higher priority of the corresponding BLER, and CSI part1 includes a CQI with a larger BLER or a CQI with a lower priority of the corresponding BLER. Or for example, the CQI corresponding to the first transport block may be placed in CSI part2, and the CQI corresponding to the second transport block may be placed in CSI part1, that is, CSI part1 includes the CQI corresponding to the first transport block, CSIpart2 includes the CQI corresponding to the second transport block, and so on.

Wherein the terminal device is the CSI report obtained by measuring the first transport block and the second transport block.

Further, if the CSI part1 includes at least two CQIs, the ordering of the CQIs in the CSI part1 may also be included, and may also be ordered according to at least one of the following rules:

sorting according to BLER corresponding to CQI;

ordered in order from wideband CQI to sub-band CQI.

For example, the CQI with a smaller BLER or the CQI with a higher priority of the BLER may be placed at the front of CSIpart1, while the CQI with a larger BLER or the CQI with a lower priority of the BLER may be placed at the rear of CSIpart1, it is also understood that the front position of CSI part1 includes the CQI with a smaller BLER or the CQI with a higher priority of the BLER, and the rear position of CSI part1 includes the CQI with a larger BLER or the CQI with a lower priority of the BLER.

For example, the CSI part1 includes a first CQI and a fourth CQI, the first CQI may be placed before the fourth CQI.

Or for example, the CQI corresponding to the first transport block is placed at the position before the CSI part1, and the CQI corresponding to the second transport block is placed at the position after the CSI part1, it can also be understood that the CQI corresponding to the first transport block is included at the position before the CSI part1, and the CQI corresponding to the second transport block is included at the position after the CSI part 1.

For example, the CSI part1 includes a first CQI and a second CQI, the first CQI may be placed before the second CQI.

Of course, any two of the above ordering manners may be combined, for example, the corresponding CQI with smaller BLER or the corresponding BLER may have higher priority and the CQI corresponding to the first transport block may be placed at the position before CSI part1, the corresponding CQI with larger BLER or the corresponding BLER may have lower priority and the CQI corresponding to the first transport block may be placed at the position next to CSI part1, the corresponding CQI with smaller BLER or the corresponding BLER may have higher priority and the CQI corresponding to the second transport block may be placed at the position next to CSI part1, the corresponding CQI with larger BLER or the corresponding BLER may have lower priority and the CQI corresponding to the second transport block may be placed at the position next to CSI part1, and it is understood that the position next to CSI part1 may include the corresponding CQI with smaller BLER or the corresponding BLER having higher priority and the corresponding CQI of the first transport block, the later positions of the CSI part1 include the CQI corresponding to the BLER larger or the CQI corresponding to the BLER lower in priority, and the CQI corresponding to the second transport block. Arranging transmission blocks first, and then, transmitting the CQI corresponding to the first transmission block and the CQI corresponding to the second transmission block; and then BLER is arranged, when one transport block corresponds to at least two BLERs, the CQI corresponding to the first BLER is firstly arranged, and then the CQI corresponding to the second BLER is arranged.

For example, the CSI part1 includes a first CQI and a third CQI, the first CQI may be placed before the third CQI.

Of course, the embodiment of the present application is not limited to this, for example, a CQI with a corresponding larger BLER or a CQI with a corresponding lower BLER priority may be placed at a position before CSI part1, a CQI with a corresponding smaller BLER or a CQI with a corresponding higher BLER priority may be placed at a position after CSI part1, that is, a position after CSI part1 includes a CQI with a corresponding smaller BLER or a CQI with a corresponding higher BLER priority, and a position before CSI part1 includes a CQI with a corresponding larger BLER or a CQI with a corresponding lower BLER priority. Or for example, the CQI corresponding to the first transport block may be placed at a position behind the CSI part1, the CQI corresponding to the second transport block may be placed at a position ahead of the CSIpart1, that is, the position behind the CSI part1 includes the CQI corresponding to the first transport block, the position ahead of the CSI part includes the CQI corresponding to the second transport block, and so on.

If the CSI part2 includes at least two CQIs, the ordering of the CQIs in the CSI part2 is also similar to the ordering in the CSIpart1, which is not described in detail.

As a second example, the CSI report includes CSI part1, CSI part1 includes at least one of:

the CSI part1 includes a first CQI and a fourth CQI; and the combination of (a) and (b),

the CSI part1 includes a second CQI and a third CQI.

The CSI described in the second example includes CSI part1, which is understood to include CSI part1 only, and then, in the case of including CSI part1 only, the CQI included in CSI part1 needs to correspond to the first BLER and the second BLER, so that the condition that the CSI report can correspond to the first BLER and the second BLER is satisfied.

In the second example, the order of the CQIs in the CSI part1 may not be limited, for example, the order of the CQIs in the CSI part1 may be random, or may be ordered according to at least one of the following rules:

sorting according to BLER corresponding to CQI;

ordered in order from wideband CQI to sub-band CQI.

Specifically, reference may be made to the introduction of the ordering of the CQIs in the CSI part1 in the first example.

As a third example, the CSI report includes CSI part2, CSI part2 includes at least one of:

the CSI part2 includes a first CQI and a fourth CQI; and the combination of (a) and (b),

the CSI part2 includes a second CQI and a third CQI.

The CSI described in the third example includes CSI part2, which is understood to include CSI part2, and then, in the case of including CSI part2, the CSI part2 includes the CQI corresponding to the first BLER and the second BLER, so as to satisfy the condition that the CSI report can correspond to the first BLER and the second BLER.

In a third example, the order of the CQIs in the CSI part2 may not be limited, for example, the order of the CQIs in the CSI part2 may be random, or may be ordered according to at least one of the following rules:

sorting according to BLER corresponding to CQI;

ordered in order from wideband CQI to sub-band CQI.

When the above three examples are introduced, the first BLER is smaller than the second BLER, or the priority of the first BLER is higher than the priority of the second BLER, which is not limited in practical application, for example, the first BLER may be larger than the second BLER, or the priority of the first BLER may be larger than the priority of the second BLER.

The order of the CQI in the CSI report is described below by some tables.

Example one.

In the introduction of example one, the first CQI and the second CQI correspond to a first BLER, the third CQI and the fourth CQI correspond to a second BLER, the first CQI and the fourth CQI are wideband CQIs, the second CQI and the third CQI are subband CQIs, and the first BLER is equal to 10e-5 and the second BLER is equal to 10e-3 as an example.

In addition, in an example one, the ordering order of the CQIs in the CSI report is that the CQIs are ordered according to the order from the wideband CQI to the subband CQI, the BLERs corresponding to the CQIs are ordered from small to large in the wideband CQI, and the BLERs corresponding to the CQIs are ordered from small to large in the subband CQI. In addition, for sub-band CQI, the example one also takes as an example the ordering in order from even sub-band CQI to odd sub-band CQI.

Tables 24-28 below are examples of CSI reports carried on PUCCH.

When the PMI includes a wideband PMI and the CQI includes a wideband CQI, table 24 shows an example of a mapping order of the CSI report n, where the wideband CQI includes a first CQI and a fourth CQI:

Where the wideband CQI corresponding to a BLER of 10e-5 is the first CQI and the wideband CQI corresponding to a BLER of 10e-3 is the fourth CQI. It can be seen that in table 24, the mapping position of the corresponding first CQI having a smaller BLER is located at the upper part of the mapping position of the corresponding fourth CQI having a larger BLER.

When the PMI includes a subband PMI, or the CQI includes a subband CQI, table 25 shows a mapping order schematic of CSI part1 included in the CSI report n, where the subband CQI includes a second CQI and a third CQI:

It can be seen that in table 25, the mapping position of the wideband CQI is above the mapping position of the sub-band CQI, and in the wideband CQI, the mapping position of the CQI having a smaller BLER is above the mapping position of the CQI having a larger BLER, which is the same for the sub-band CQI.

Wherein the sub-band differential CQI for the second transport block corresponding to the even sub-band of BLER 10e-5 and the sub-band differential CQI for the second transport block corresponding to the odd sub-band of BLER 10e-5 are both second CQIs, and the sub-band differential CQI for the second transport block corresponding to the even sub-band of BLER 10e-3 and the sub-band differential CQI for the second transport block corresponding to the odd sub-band of BLER 10e-5 are both third CQIs. It can be seen that in table 27, the mapping positions of the even sub-band CQIs are above the mapping positions of the odd sub-band CQIs, and the mapping positions of the corresponding CQI with smaller BLER are above the mapping positions of the corresponding CQI with larger BLER.

Table 28 shows an exemplary mapping order of CSI part1 included in CSI report n, including CRI/RSRP or SSB/RSRP:

It can be seen that in table 28, the mapping position of the wideband CQI is above the mapping position of the sub-band CQI, and in the wideband CQI, the mapping position of the CQI having a smaller BLER is above the mapping position of the CQI having a larger BLER, which is the same for the sub-band CQI.

It can be seen that in table 30, the mapping positions for even sub-band CQIs are above the mapping positions for odd sub-band CQIs, and the mapping positions for the corresponding lesser BLER CQIs are above the mapping positions for the corresponding greater BLER CQIs.

Example two.

In the introduction of example two, the first CQI and the second CQI correspond to a first BLER, the third CQI and the fourth CQI correspond to a second BLER, the first CQI and the fourth CQI are wideband CQIs, the second CQI and the third CQI are subband CQIs, and the first BLER is equal to 10e-5 and the second BLER is equal to 10e-3 as an example.

In addition, in the second example, the ordering order of the CQIs in the CSI report is, for example, ordered according to the BLER corresponding to the CQI from small to large, and further ordered according to the order from the wideband CQI to the subband CQI. In addition, for sub-band CQI, example two also takes as an example the ordering in order from even sub-band CQI to odd sub-band CQI.

Tables 31-33 below are examples of CSI reports carried on PUCCH.

When the PMI includes a subband PMI, or the CQI includes a subband CQI, table 31 shows a schematic mapping order of CSI part1 included in the CSI report n, where the subband CQI includes a second CQI and a third CQI:

And in the CSI part1, the wideband is arranged in the order of the preceding subband to the following subband.

Wherein the wideband CQI for the first transport block corresponding to a BLER of 10e-3 is the fourth CQI, the wideband CQI for the second transport block corresponding to a BLER of 10e-5 is the second CQI, and the wideband CQI for the second transport block corresponding to a BLER of 10e-3 is the third CQI.

In CSIpart2, the first transport block is arranged in the first order and the second transport block is arranged in the second order.

In the foregoing description, the CSI report includes the CQI corresponding to the first BLER and the CQI corresponding to the second BLER is mainly taken as an example. It may also be the case that the CSI report comprises a CQI corresponding to at least one BLER and comprises a CQI without a corresponding BLER, which may be understood as a BLER that is not configured.

For the CQI without configured BLER, in the CSI report, if the CQI is ordered according to the transport block corresponding to the CQI, the position of the CQI may be ordered according to the corresponding transport block, which may refer to the foregoing description. If the CQI is sorted according to the BLER corresponding to the CQI, or according to the BLER corresponding to the CQI and the transport block corresponding to the CQI, in short, if the CQI refers to the BLER during sorting, the CQI without the BLER configured may be treated as the CQI with the largest BLER or the lowest priority of the BLER, which is, of course, sorted in the order from small to large BLER or in the order from high to low BLER, and if the CQI without the BLER configured is sorted in the order from large to small BLER or in the order from low to high BLER, the CQI without the BLER configured may be treated as the CQI with the smallest BLER or the highest BLER priority.

The examples one to three described above are only examples, and are not limited to the above tables in practical applications, and various implementation forms are possible.

In the embodiment of the present application, even for the content of one CSI report, the CSI report may be sorted according to BLER, so that the content with lower BLER or higher BLER priority is ranked as before as possible, and the content with lower BLER or higher BLER priority is generally the content with higher reliability, so that by this way, the transmission performance and the delay may be ensured as much as possible, and if the CSI report is carried on the PUCCH, it may be ensured that the CQI with high reliability may not be dropped when the capacity is limited.

In the embodiment shown in fig. 2 or the embodiment shown in fig. 3, how the terminal device should sort when reporting the CSI report is described. However, the CSI report may include CQI, and currently, by the NR system, two CQI tables corresponding to different BLERs may be supported, and during the communication between the base station and the terminal device, the corresponding CQI table may be selected to be used, so as to determine that a certain CQI in a certain CQI table is reported. In order for the base station and the terminal device to select the same CQI table, the base station needs to indicate the specifically used CQI table to the terminal device when scheduling the terminal device.

The currently supported way for the base station to notify the terminal device of the CQI table is to use high-level signaling for notification, and before the terminal device receives a new high-level signaling notification, the terminal device uses the previous CQI table by default. The URLLC service has high requirement on time delay, and the base station can flexibly and dynamically select the used CQI table according to the actual condition of the terminal equipment when the URLLC service arrives. However, since the used table is notified to the terminal device through the high layer signaling, and the high layer signaling is semi-static, the terminal device cannot be notified of the selected CQI table in time, and the terminal device will continue to use the CQI table selected before.

In view of this, the present embodiment also provides a third communication method, for enabling the manner of indicating the CQI to the terminal device to adapt to the requirement of the URLLC service, please refer to fig. 4. In the following description process, the application scenario shown in fig. 1 is taken as an example to which the technical solution of the embodiment of the present application is applied. The flow of the method is described below.

S41, the terminal equipment determines first information, and the first information is used for determining CQI; wherein determining the first information comprises at least one of:

determining first information according to the received DCI;

determining first information according to the resource of the CQI; and the combination of (a) and (b),

determining first information according to the information of the CSI containing the CQI;

s42, the terminal equipment determines a CQI index corresponding to the CQI according to the first information;

s43, the terminal equipment sends CQI index to the network equipment, and then the network equipment receives the CQI index;

s44, the network device determines the CQI corresponding to the CQI index.

In the embodiment of the present application, the CQI may include at least one of a modulation scheme, a coding rate, and an efficiency value.

In the following, two concepts will be referred to, a first CQI index and a second CQI index. Wherein the first CQI index and the second CQI index may satisfy:

the BLER corresponding to the second CQI index is smaller than the BLER corresponding to the first CQI index, for example, the BLER corresponding to the second CQI index is 10e-5, and the BLER corresponding to the first CQI index is 10 e-3; or the like, or, alternatively,

the BLER corresponding to the second CQI index has a higher priority than the BLER corresponding to the first CQI index.

Alternatively, the first CQI index and the second CQI index may satisfy:

the BLER corresponding to the second CQI index is greater than the BLER corresponding to the first CQI index, for example, the BLER corresponding to the first CQI index is 10e-5, and the BLER corresponding to the second CQI index is 10 e-3; or the like, or, alternatively,

the BLER corresponding to the second CQI index has a lower priority than the BLER corresponding to the first CQI index.

In the following description, unless otherwise specified, the BLER corresponding to the second CQI index is smaller than the BLER corresponding to the first CQI index, or the priority of the BLER corresponding to the second CQI index is higher than the priority of the BLER corresponding to the first CQI index is mainly taken as an example. However, the embodiment of the present application does not limit the size relationship between the BLER corresponding to the first CQI index and the BLER corresponding to the second CQI index, nor the relationship between the priority of the BLER corresponding to the first CQI index and the priority of the BLER corresponding to the second CQI index. The first CQI index and the second CQI index may be the same or different.

Specifically, the terminal device may determine, according to the first information, to which CQI table the CQI to be reported belongs, so that the terminal device performs measurement according to the BLER corresponding to the CQI table to obtain the CQI, the terminal device determines a CQI index corresponding to the CQI in the selected CQI table, and sends the CQI index to the network device, so that the network device receives the CQI index, and the network device can determine the CQI corresponding to the CQI index by querying the CQI table, so that the network device can determine the CQI reported by the terminal device. That is, in one embodiment, the first information indicates a CQI table.

In this embodiment of the present application, the terminal device determines the first information, and there may be different determining manners, for example, the terminal device determines the first information, including but not limited to at least one of the following manners:

A. determining first information according to the received DCI;

B. determining first information according to the resource of the CQI;

C. determining first information according to information of CSI including the CQI.

Several ways of determining the first information are described below.

A. And the terminal equipment determines the first information according to the received DCI.

In the method a, before S41, the network device also sends DCI to the terminal device, and the terminal device receives the DCI. The first information determined by the terminal device according to the DCI may include a variety of different information. As a first example in the mode a, the first information determined by the terminal device includes, but is not limited to, at least one of the following:

a Modulation Coding Scheme (MCS) index indicated by the DCI;

a coding rate indicated by the DCI;

a scheduled Transport Block Size (TBS) indicated by the DCI;

a feedback time interval indicated by the DCI, wherein the feedback time interval is a time interval from the DCI to a time domain resource carrying the CQI; and the combination of (a) and (b),

and (5) detecting DCI.

Accordingly, in the method a, the network device may directly determine the first information, and the first information determined by the network device includes, but is not limited to, at least one of the following:

modulation coding mode index;

coding rate;

scheduling a transport block size;

a feedback time interval, which is a time interval from the DCI to a time domain resource carrying the CQI; and the combination of (a) and (b),

and (5) detecting DCI.

The first information determined by the terminal device and the first information determined by the network device should be the same, for example, both the terminal device and the network device determine that the first information includes the carrier where the DCI is located.

In the following description, the first information is mainly described in terms of the terminal device, and MCS information and the like corresponding to the MCS index are determined according to the first information.

Next, the first information as above is described separately.

A1, the first information includes MCS index indicated by DCI.

The network device may indicate an MCS index (index) through the DCI, and the terminal device may determine the MCS index according to the received DCI, specifically, include an MCS field (field) in the DCI, and the MCS field may indicate the MCS index. Of course, in other cases to be described later, the MCS index may also be indicated by higher layer signaling or may be configured in advance by a protocol, and the case where the MCS index is indicated by DCI is mainly described here.

In this embodiment, the terminal device determines the MCS index, and thus determines the CQI index corresponding to the CQI according to the MCS index.

For example, the value of the MCS index indicated by the DCI belongs to at least one of a plurality of value sets, and the plurality of value sets include a first value set and a second value set.

Specifically, the value of the MCS index indicated by the DCI belongs to a first value set, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the value of the MCS index indicated by the DCI belongs to a second value set, and the terminal device determines that the CQI index corresponding to the CQI is the second CQI index. Or, it is understood that the value of the MCS index indicated by the DCI belongs to a first value set, and the CQI index corresponding to the CQI is a first CQI index, or the value of the MCS index indicated by the DCI belongs to a second value set, and the CQI index corresponding to the CQI is a second CQI index.

The value of the MCS index belongs to a first value set, it can be understood that the value of the MCS index is greater than or equal to the first value, and the value of the MCS index belongs to a second value set, it can be understood that the value of the MCS index is smaller than the second value, the first value and the second value are two threshold values, which can be specified by a protocol or preset by a network device and inform a terminal device through a high-level signaling or a dynamic signaling, and the first value and the second value may be equal or unequal, for example, the first value is greater than the second value.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the value of the index of the MCS is greater than or equal to the first value, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain CQI, the terminal equipment inquires in the first CQI table to determine the CQI index corresponding to the CQI, or if the value of the index of the MCS is less than the second value, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

It can be understood that, the larger the MCS index is, the better the channel quality of the terminal equipment is indicated, and when the terminal equipment only supports URLLC service, for such a case, the terminal equipment may use the CQI table with lower BLER or higher BLER priority for feedback, so as to achieve higher reliability. If the MCS index is smaller, it indicates that the channel quality of the terminal equipment is poor, and when the terminal equipment only supports URLLC service, the terminal equipment can use the CQI table with higher BLER or lower BLER priority to perform feedback, so as to ensure the basic reliability.

Or, the value of the MCS index indicated by the DCI belongs to at least one of a plurality of value sets, where the plurality of value sets include a first value set and a second value set, and then, in terms of describing the value sets, the scheme of embodiment a1 may also be described as follows: the CQI index corresponding to the CQI corresponding to the MCS index included in the first value set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the MCS index included in the second value set is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the MCS index included in the first value set is a first CQI index, and it should be understood that when the MCS index indicated by the DCI belongs to the first value set, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the MCS index indicated by the DCI belongs to the first value set or the second value set, and therefore, the corresponding relationship between the MCS index and the CQI index or the corresponding relationship between the value set of the MCS index and the CQI index should be emphasized here instead of the corresponding relationship between the MCS index (or the value set of the MCS index) and the CQI index. For the understanding that the CQI index corresponding to the CQI corresponding to the MCS index included in the second value set is the second CQI index, the same is also true.

In this document, it is exemplified that a value of an index of an MCS is greater than or equal to a first value, and the determined CQI indexes are all first CQI indexes, and in fact, when the value of the index of the MCS is equal to the first value, the determined CQI index may not be the first CQI index, for example, the first value is equal to a second value, it may be that the value of the index of the MCS is greater than or equal to the first value, the determined CQI indexes are all first CQI indexes, the value of the index of the MCS is smaller than the first value, and the determined CQI index is the second CQI index, or it may be that the value of the index of the MCS is greater than the first value, the determined CQI index is the first CQI index, the value of the index of the MCS is smaller than or equal to the first value, and the determined CQI index is the second CQI index.

That is, how to divide the "equal" is not limited herein, and in the following description, when the range is divided, all cases related to "equal" are similar to this, and will not be described in detail in the following description.

In this manner, the network device may also determine the first information from the DCI.

A2, the first information includes the coding rate indicated by the DCI.

In this embodiment, the terminal device determines the coding rate indicated by the DCI, so as to determine the CQI index corresponding to the CQI according to the coding rate.

For example, the coding code rate of the MCS indicated by the DCI belongs to at least one of a plurality of code rate sets, the plurality of code rate sets including a first code rate set and a second code rate set.

Specifically, the coding rate of the MCS indicated by the DCI belongs to a first code rate set, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI information, or the coding rate of the MCS indicated by the DCI belongs to a second code rate set, and the terminal device determines that the CQI information corresponding to the CQI is the second CQI index. Or, the coding rate of the MCS indicated by the DCI belongs to a first code rate set, and the CQI index corresponding to the CQI is first CQI information, or the coding rate of the MCS indicated by the DCI belongs to a second code rate set, and the CQI information corresponding to the CQI is a second CQI index.

The coding rate of the MCS belongs to a first code rate set, it can be understood that the coding rate of the MCS is smaller than the first code rate, and the coding rate of the MCS belongs to a second code rate set, it can be understood that the coding rate of the MCS is greater than or equal to the second code rate, the first code rate and the second code rate are used as two threshold values, which may be specified by a protocol or may be preset by a network device, and inform a terminal device through a high-level signaling or a dynamic signaling, where the first code rate and the second code rate may be equal or unequal, for example, the second code rate is greater than the first code rate.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the coding rate of the MCS is less than the first code rate, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or if the coding rate of the MCS is greater than or equal to a second code rate, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Or the coding code rate of the MCS indicated by the DCI belongs to at least one of multiple code rate sets, where the multiple code rate sets include a first code rate set and a second code rate set, and then from the viewpoint of describing the code rate sets, the scheme of embodiment a2 may also be described as follows: the CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the first code rate set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the second code rate set is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the first code rate set is a first CQI index, which is to be understood that when the coding rate of the MCS indicated by the DCI belongs to the first code rate set, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the coding rate of the MCS indicated by the DCI belongs to the first set of code rates or the second set of code rates, and therefore, the emphasis should be on the correspondence between the coding rate of the MCS and the CQI index, or the correspondence between the set of code rates of the coding rate of the MCS and the CQI index, rather than the correspondence between the coding rate of the MCS (or the set of code rates of the coding rate of the MCS) and the CQI index. For the understanding that the CQI index corresponding to the CQI corresponding to the coding rate of the MCS included in the second code rate set is the second CQI index, the same is also true.

It can be understood that the larger the code rate of the MCS is, the better the channel quality of the terminal equipment is indicated, and when the terminal equipment only supports URLLC service, for such a case, the terminal equipment may use the CQI table with lower BLER or higher BLER priority to ensure higher reliability. If the code rate of the MCS is smaller, it indicates that the channel quality of the terminal equipment is required to be poor, and the terminal equipment only supports the URLLC service, the terminal equipment can adopt the CQI table with higher BLER or lower BLER priority to perform feedback, so as to ensure the basic reliability.

In this embodiment, the case of "equal" is also divided, and similarly to the embodiment a1, this embodiment is also only an example of dividing the case where the coding rate of MCS is equal to the second code rate into the case where the coding rate of MCS is greater than the second code rate, but the present invention is not limited to this. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

A3, the first information includes the scheduled transport block size indicated by the DCI.

In this embodiment, the terminal device determines the size of the scheduling transport block indicated by the DCI, and thus determines the CQI index corresponding to the CQI according to the size of the scheduling transport block.

For example, the scheduled transport block size indicated by the DCI belongs to one of a plurality of transport block size sets, including a first transport block size set and a second transport block size set.

Specifically, the scheduled transport block size indicated by the DCI belongs to a first transport block size set, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the scheduled transport block size indicated by the DCI belongs to a second transport block size set, and the terminal device determines that the CQI index corresponding to the CQI is the second CQI index. Alternatively, it may be understood that the scheduled transport block size indicated by the DCI belongs to a first transport block size set and the CQI index corresponding to the CQI is a first CQI index, or that the scheduled transport block size indicated by the DCI belongs to a second transport block size set and the CQI index corresponding to the CQI is a second CQI index.

The size of the scheduled transport block belongs to a first transport block size set, it can be understood that the size of the scheduled transport block is greater than or equal to the size of the first transport block, and the size of the scheduled transport block belongs to a second transport block size set, it can be understood that the size of the scheduled transport block is smaller than the size of the second transport block, the size of the first transport block and the size of the second transport block are used as two threshold values, which can be specified by a protocol or can be preset by a network device, and inform a terminal device through a high-level signaling or a dynamic signaling, the size of the first transport block and the size of the second transport block can be equal or unequal, for example, the size of the first transport block is greater than the size of the second transport block.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the size of the scheduling transmission block is larger than or equal to the size of the first transmission block, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or if the size of the scheduling transmission block is smaller than the size of the second transmission block, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Or, the scheduled transport block size indicated by the DCI belongs to at least one of a plurality of transport block size sets, where the plurality of transport block size sets includes a first transport block size set and a second transport block size set, then, from the viewpoint of describing the transport block size sets, the scheme of embodiment a3 may also be described as follows: the CQI index corresponding to the CQI corresponding to the scheduling transport block size included in the first transport block size set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the scheduling transport block size included in the second transport block size set is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the scheduled transport block size included in the first transport block size set is a first CQI index, and it should be understood that when the scheduled transport block size indicated by the DCI belongs to the first transport block size set, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the scheduled transport block size indicated by the DCI belongs to the first set of transport block sizes or the second set of transport block sizes, and therefore, emphasis should be made here on the correspondence between the scheduled transport block size and the CQI index, or the correspondence between the set of transport block sizes of the scheduled transport block size and the CQI index, rather than the correspondence between the scheduled transport block size (or the set of transport block sizes of the scheduled transport block size) and the CQI index. For the understanding that the CQI index corresponding to the CQI corresponding to the scheduling transport block size included in the second transport block size set is the second CQI index, the same is also true.

It can be understood that the smaller the size of the scheduled transport block indicates the more urgent the service is, such service may be the URLLC service, or other more urgent service, for which the CQI table with the lower BLER or higher BLER priority may be used to ensure reliability. If the larger the scheduled transport block size, the less urgent the service is, and the reliability requirement of such service is generally not very high, then for such service, a CQI table with higher BLER or lower BLER priority may be used.

In this embodiment, the case of "equal" division also occurs, and similar to the embodiment a1, this embodiment also only exemplifies the case of dividing the scheduled transport block size equal to the first transport block size in accordance with the case of the scheduled transport block size larger than the first transport block size, but is not limited to this actually. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

A4, the first information includes a feedback time interval indicated by the DCI, and the feedback time interval is a time interval from the DCI to a time domain resource carrying the CQI.

In this embodiment, the terminal device determines the feedback time interval indicated by the DCI, so as to determine the CQI index corresponding to the CQI according to the feedback time interval.

For example, the feedback time interval indicated by the DCI belongs to at least one of a plurality of time interval sets, the plurality of time interval sets including a first time interval set and a second time interval set.

Specifically, the feedback time interval indicated by the DCI belongs to a first time interval set, and the CQI index corresponding to the CQI is a first CQI index, or the feedback time interval indicated by the DCI belongs to a second time interval set, and the CQI index corresponding to the CQI is a second CQI index.

The feedback time interval belongs to a first time interval set, it may be understood that the feedback time interval is greater than or equal to the first time interval, and the feedback time interval belongs to a second time interval set, it may be understood that the feedback time interval is smaller than the second time interval, the first time interval and the second time interval serve as two threshold values, which may be specified by a protocol or may be preset by a network device, and inform a terminal device through high-level signaling or dynamic signaling, where the first time interval and the second time interval may be equal or unequal, for example, the first time interval is greater than the second time interval.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the feedback time interval belongs to the first time interval set, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or if the feedback time interval belongs to the second time interval set, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Or the feedback time interval indicated by the DCI belongs to at least one of a plurality of time interval sets, where the plurality of time interval sets includes a first time interval set and a second time interval set, then, from the viewpoint of describing the time interval sets, the scheme of embodiment a4 may also be described as: the CQI index corresponding to the CQI corresponding to the feedback time interval included in the first time interval set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the feedback time interval included in the second time interval set is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the feedback time interval included in the first time interval set is a first CQI index, and it should be understood that when the feedback time interval indicated by the DCI belongs to the first time interval set, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the feedback time interval indicated by the DCI belongs to the first set of time intervals or the second set of time intervals, and therefore, emphasis should be made here on the correspondence between the feedback time interval and the CQI index, or the correspondence between the set of time intervals of the feedback time interval and the CQI index, rather than the correspondence between the feedback time interval (or the set of time intervals of the feedback time interval) and the CQI index. For the understanding that the CQI index corresponding to the CQI corresponding to the feedback time interval included in the second time interval set is the second CQI index, the same is also true.

It can be understood that a shorter feedback time interval indicates a more urgent service, which may be a URLLC service, or other more urgent service, and for such a service, a CQI table with a lower BLER or a higher BLER priority may be used to ensure reliability. If the feedback interval is longer, indicating that the service is not very urgent, and the reliability requirement for such service is generally not very high, then for such service, a CQI table with higher BLER or lower BLER priority may be used.

In this embodiment, the case of dividing "equal" also occurs, and similarly to the embodiment a1, this embodiment also merely exemplifies the case of dividing the feedback time interval equal to the first time interval into the case of matching the feedback time interval greater than the first time interval, and is not limited to this actually. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

Herein, the "time instant" may be explained by a concept of an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a slot (slot), or a mini-slot (mini-slot), and hereinafter, the time instant is explained by the symbol or the slot as an example.

For example, the feedback time interval may refer to a time interval from a time when the network device transmits DCI to a time when the terminal device transmits CQI.

Specifically, the feedback time interval may refer to a time interval from a start time of a symbol at which the time when the network device transmits DCI is located to a start time of a symbol at which the terminal device transmits CQI, or the feedback time interval may refer to a time interval from an end time of a symbol at which the network device transmits DCI to a start time of a symbol at which the terminal device transmits CQI, or the feedback time interval may refer to a time interval indicated by a difference between an index of a symbol at which the time when the network device transmits DCI is located and an index of a symbol at which the terminal device transmits CQI, or the feedback time interval may refer to a time interval from a start time of a slot at which the time when the network device transmits DCI is located to a start time of a slot at which the terminal device transmits CQI, alternatively, the feedback time interval may refer to a time interval from an end time of a time slot at which the network device transmits DCI to a start time of a time slot at which the terminal device transmits CQI, or the feedback time interval may refer to a time interval indicated by a difference between an index of the time slot at which the network device transmits DCI and an index of the time slot at which the terminal device transmits CQI.

And A5, the first information comprises the detection period of the DCI.

In this embodiment, the terminal device determines the DCI detection period, so as to determine the CQI index corresponding to the CQI according to the DCI detection period.

For example, the detection period of the DCI belongs to at least one of a plurality of detection period sets, which include a first detection period set and a second detection period set.

Specifically, the detection period of the DCI belongs to a first detection period set, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the detection period of the DCI belongs to a second detection period set, and the terminal device determines that the CQI index corresponding to the CQI is the second CQI index. Or, the detection period of the DCI belongs to a first detection period set, and the CQI index corresponding to the CQI is a first CQI index, or the detection period of the DCI belongs to a second detection period set, and the CQI index corresponding to the CQI is a second CQI index.

The detection period of the DCI belongs to the first detection period set, it may be understood that the detection period of the DCI is greater than or equal to the first detection period, and the detection period of the DCI belongs to the second detection period set, it may be understood that the detection period of the DCI is smaller than the second detection period, and the first detection period and the second detection period serve as two thresholds, which may be specified by a protocol or may be preset by a network device and notified to a terminal device by a high-level signaling or a dynamic signaling.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the detection period of the DCI belongs to the first detection period set, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or if the detection period of the DCI belongs to the second detection period set, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Or, the detection period of the DCI belongs to at least one of a plurality of detection period sets, where the plurality of detection period sets includes a first detection period set and a second detection period set, and then, in terms of describing the detection period sets, the scheme of embodiment a5 may also be described as: the CQI index corresponding to the CQI corresponding to the detection period included in the first detection period set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the detection period included in the second detection period is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the detection period included in the first detection period set is a first CQI index, and it should be understood that when the detection period of the DCI belongs to the first detection period set, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the DCI detection period belongs to the first set of detection periods or the second set of detection periods, and therefore, emphasis should be given here to the correspondence between the DCI detection period and the CQI index, or the correspondence between the DCI detection period set and the CQI index, rather than the correspondence between the DCI detection period (or DCI detection period set) and the CQI index. For the understanding that the CQI index corresponding to the CQI corresponding to the detection period of the DCI included in the second detection period set is the second CQI index, the same is also true.

It can be understood that the shorter the detection period of DCI indicates the more urgent the need is, and such traffic may be URLLC traffic or other more urgent traffic, and for such traffic, a CQI table with lower BLER or higher BLER priority may be used to ensure reliability. If the detection period of DCI is long, indicating that the requirement is not very urgent, and the requirement for reliability for such services is not very high in general, a CQI table with higher BLER or lower BLER priority may be used for such services.

In this embodiment, the case of "equal to" is also divided, and similarly to embodiment a1, this embodiment is also only an example of dividing the case where the detection period of DCI is equal to the first detection period into the same cases as the case where the detection period of DCI is greater than the first detection period, and the present invention is not limited to this. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

Wherein, each embodiment in the mode A can be independently applied, or any several embodiments can be combined to be applied. One content of the first information may be considered as one embodiment.

The manner of determining the first information according to the DCI is described above, and the second manner of determining the first information is described below.

B. And determining the first information according to the resource of the CQI.

The resource where the CQI is located may be understood as a resource carrying the CQI. Since the terminal device has not sent the CQI when determining the first information, i.e. the resource is only to be used for carrying the CQI but not yet carrying the CQI, the resource is referred to herein as the resource where the CQI is located.

In the mode B, the determined first information may also have one or more, for example, the first information includes at least one of the following:

a carrier (carrier) on which a resource on which the CQI is located;

a cell (cell) in which a resource in which the CQI is located;

BWP where the resource where CQI is located;

a TAG where a resource where the CQI is located;

the PUCCH group where the resource where the CQI is located;

a PUCCH format corresponding to a resource in which the CQI is located;

the subcarrier interval of the resource where the CQI is located;

the waveform of the resource where the CQI is located;

time domain length of the resource where the CQI is located.

The terminal device determines the resource where the CQI is located, or may determine the resource where the CQI is located through DCI, for example, the DCI may indicate the resource where the CQI is located, before S41, the network device may send DCI to the terminal device, and the terminal device receives the DCI. Alternatively, the resource where the CQI is located may also be specified by a protocol, or the terminal device may also determine the resource where the CQI is located through higher layer signaling or other dynamic signaling.

In the method B, the terminal device and the network device determine the first information in the same manner, and the determined first information is also the same.

In the following description, the first information is mainly described in terms of a terminal device, and the process of determining the first information, or the content of the determined first information, is also similar for the network device.

The following describes the above first information respectively.

B1, the first information includes the carrier where the resource of CQI is located.

In this embodiment, the terminal device determines the carrier where the resource where the CQI is located, so as to determine the CQI index corresponding to the CQI according to the carrier where the resource where the CQI is located.

For example, the carrier where the resource where the CQI is located is at least one of a plurality of carriers, and the plurality of carriers includes a first carrier and a second carrier.

Specifically, the carrier where the resource where the CQI is located is a first carrier, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the carrier where the resource where the CQI is located is a second carrier, and the terminal device determines that the CQI index corresponding to the CQI is the second CQI index. Or, it is understood that the carrier where the resource where the CQI is located is the first carrier and the CQI index corresponding to the CQI is the first CQI index, or the carrier where the resource where the CQI is located is the second carrier and the CQI index corresponding to the CQI is the second CQI index.

For example, the first carrier is a carrier that carries other services except the URLLC service, as described above, the system supports multiple CQI tables, and for example, 2 CQI tables are supported, the terminal device may determine, according to the fact that the carrier where the resource where the CQI is located is the first carrier, to select a CQI table with a larger BLER or a lower BLER priority, for example, to select a first MCS table, measure according to the first BLER, to obtain a CQI, and query, by the terminal device, in the first CQI table, the CQI index corresponding to the CQI is determined. Or, for example, the second carrier is a carrier carrying the URLLC service, and continuing to use 2 CQI tables supported by the system as an example, the terminal device may determine to select a CQI table with a lower BLER or a higher BLER priority according to that the carrier where the resource where the CQI is located is the second carrier, for example, the terminal device selects the second CQI table, measures according to the second BLER to obtain the CQI, and the terminal device queries in the second CQI table to determine the CQI index corresponding to the CQI.

Or, the carrier where the resource where the CQI is located is at least one of multiple carriers, where the multiple carriers include a first carrier and a second carrier, and then, from the viewpoint of describing the carriers, the scheme of embodiment B1 may also be described as: the CQI index corresponding to the CQI corresponding to the first carrier is a first CQI index, and the CQI index corresponding to the CQI corresponding to the second carrier is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the first carrier is the first CQI index, and it should be understood that when the carrier where the resource where the CQI is located is the first carrier, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the carrier on which the resource on which the CQI is located is the first carrier or the second carrier, and therefore, the emphasis here should be on the correspondence between the carrier on which the resource on which the CQI is located and the CQI index, rather than the correspondence between the carrier on which the resource on which the CQI is located and the CQI index. For the above, the CQI index corresponding to the CQI corresponding to the second carrier is the second CQI index, which is also understood in the same way.

In addition, the first information may further include at least one of a cell where the resource where the CQI exists, a BWP where the resource where the CQI exists, a TAG where the resource where the CQI exists, a PUCCH group where the resource where the CQI exists, a subcarrier interval of the resource where the CQI exists, a PUCCH format corresponding to the resource where the CQI exists, and a waveform of the resource where the CQI exists, which is similar to the case where the first information includes the carrier where the resource where the CQI exists, and therefore, the description is given together in embodiment B1.

Take the cell where the first information includes the resource where the CQI is located as an example. For example, the system or protocol may specify that certain cells correspond to CQI tables for high BLER and certain cells correspond to CQI tables for low BLER, e.g., specify that a first cell corresponds to CQI tables for high BLER and a first cell corresponds to MCS tables for low BLER. Then, the terminal device determines that the CQI index corresponding to the CQI is the first CQI index if the cell where the resource where the CQI is located is the first cell, or determines that the CQI index corresponding to the CQI is the second CQI index if the cell where the resource where the CQI is located is the second cell. Or, the cell where the resource where the CQI is located is a first cell, and the CQI index corresponding to the CQI is a first CQI index, or the cell where the resource where the CQI is located is a second cell, and the CQI index corresponding to the CQI is a second CQI index.

When the first information includes BWP where the resource where the CQI is located, TAG where the resource where the CQI is located, PUCCH group where the resource where the CQI is located, subcarrier interval of the resource where the CQI is located, PUCCH format corresponding to the resource where the CQI is located, waveform of the resource where the CQI is located, and the like, the description is omitted, similarly to the case where the first information includes the cell or carrier where the resource where the CQI is located.

B2, the first information includes the time domain length of the resource where the CQI is located.

In this embodiment, the terminal device determines the time domain length of the resource where the CQI is located, so as to determine the CQI index corresponding to the CQI according to the time domain length of the resource where the CQI is located.

For example, the time domain length of the resource where the CQI is located belongs to at least one of a plurality of sets of time domain lengths, which include a first set of time domain lengths and a second set of time domain lengths.

Specifically, the time domain length of the resource where the CQI is located belongs to a first time domain length set, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the time domain length of the resource of the CQI belongs to a second time domain length set, and the terminal device determines that the CQI index corresponding to the CQI is the second CQI index. Or, it is understood that the time domain length of the resource where the CQI is located belongs to a first time domain length set, and the CQI index corresponding to the CQI is a first CQI index, or the time domain length of the resource of the CQI belongs to a second time domain length set, and the CQI index corresponding to the CQI is a second CQI index.

The resource where the CQI is located may be a PUSCH or a PUCCH, the determined time domain length of the resource where the CQI is located may be a time domain length of a PUSCH or a PUCCH carrying the CQI, and a unit of the time domain length here may be a symbol, a slot, a mini slot, or the like, which is not limited specifically.

The time domain length of the resource where the CQI is located belongs to the first time domain length set, which can be understood as that the time domain length of the resource where the CQI is located is greater than or equal to the first time domain length, and the time domain length of the resource where the CQI is located belongs to the second time domain length set, which can be understood as that the time domain length of the resource where the CQI is located is less than the second time domain length. The first time domain length and the second time domain length are used as two threshold values, which may be specified by a protocol or preset by a network device, and are notified to a terminal device through a high-level signaling or a dynamic signaling.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the time domain length of the resource where the CQI is located belongs to the first time domain length set, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain the CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or if the time domain length of the resource where the CQI is located belongs to the first time domain length set, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Or, the time domain length of the resource where the CQI is located belongs to at least one of a plurality of time domain length sets, where the plurality of time domain length sets include a first time domain length set and a second time domain length set, and then, in terms of describing the time domain length sets, the scheme of embodiment B2 may also be described as follows: the CQI index corresponding to the CQI corresponding to the time domain length of the resource where the CQI is located and included in the first time domain length set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the time domain length of the resource where the CQI is located and included in the second time domain length set is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI and corresponding to the time domain length of the resource where the CQI is included in the first time domain length set is a first CQI index, and it should be understood that when the time domain length of the resource where the CQI is included belongs to the first time domain length set, the CQI index corresponding to the CQI is the first CQI index. Whether the time domain length of the resource where the CQI is located belongs to the first time domain length set or the second time domain length set, the CQI is unchanged, and therefore, the emphasis should be on the correspondence between the time domain length of the resource where the CQI is located and the CQI index, or the correspondence between the time domain length set and the CQI index, rather than the correspondence between the time domain length (or the time domain length set) of the resource where the CQI is located and the CQI index. For the understanding that the CQI index corresponding to the time domain length of the resource in which the CQI is included in the second time domain length set is the second CQI index, the same is true.

It can be understood that, the shorter the time domain length of the resource where the CQI is located indicates that the service is more urgent, and such a service may be the URLLC service, or other more urgent services, and for such a service, a CQI table with a lower BLER or a higher BLER priority may be used to ensure reliability. If the longer the time domain length of the resource where the CQI is located is, the service is not very urgent, and the requirement of such service for reliability is generally not very high, then for such service, a CQI table with higher BLER or lower BLER priority may be used.

In this embodiment, the case of "equal" division also occurs, and similar to the embodiment a1, this embodiment also only takes as an example the case of dividing the case where the time domain length of the resource where the CQI exists is equal to the first time domain length into the case where the time domain length of the resource where the CQI exists is greater than the first time domain length, and the present embodiment is not limited to this actually. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

Wherein, each embodiment in the mode B can be independently applied, or any several embodiments can be combined to be applied. One content of the first information may be considered as one embodiment. In addition, any of the embodiments of the mode a and the mode B can also be applied in combination.

Mode a introduces a mode of determining the first information according to DCI, mode B introduces a mode of determining the first information according to the resource where the CQI is located, and a third mode of determining the first information is described below.

C. The first information is determined according to information of CSI including CQI.

Wherein the information of the CSI may include at least one of:

information of a resource where the CSI is located (it may be understood that the first information includes information of a resource where the CSI is located);

the content of the CSI (it may be understood that the first information includes the content of the CSI);

the number of bits of the CSI.

In the method C, the terminal device and the network device determine the first information in the same manner, and the determined first information is also the same.

Described separately below.

C1, the first information includes information of the resource where the CSI is located.

Taking the length of the time domain resource occupied by the CSI included in the information of the resource where the CSI is located as an example, the embodiment of the present application is not limited thereto, and if the information of the resource where the CSI is located also includes other information of the resource occupied by the CSI, the manner of determining the first information is also similar. The length of the time domain resource occupied by the CSI may also be understood as the time domain length of the resource where the CSI is located.

In this embodiment, the terminal device determines the length of the time domain resource occupied by the CSI, so as to determine the CQI index corresponding to the CQI according to the length of the time domain resource occupied by the CSI.

For example, the length of the time domain resource occupied by the CSI belongs to at least one of a plurality of time domain length sets, which include a third time domain length set and a fourth time domain length set.

Specifically, the length of the time domain resource occupied by the CSI belongs to a third time domain length set, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the terminal device determines that the length of the time domain resource occupied by the CSI belongs to a fourth time domain length set, and the CQI index corresponding to the CQI is the second CQI index. Or, it is understood that the length of the time domain resource occupied by the CSI belongs to a third time domain length set, and the CQI index corresponding to the CQI is the first CQI index, or the length of the time domain resource occupied by the CSI belongs to a fourth time domain length set, and the CQI index corresponding to the CQI is the second CQI index.

The resource where the CSI is located may be a PUSCH or a PUCCH, the length of the time domain resource occupied by the CSI may be determined, and may be a time domain length of a PUSCH or a PUCCH for carrying the CSI, where a time domain length unit may be a symbol, a slot, a mini slot, or the like, and is not limited specifically.

The length of the time domain resource occupied by the CSI belongs to a third time domain length set, and it can be understood that the length of the time domain resource occupied by the CSI is greater than or equal to the third time domain length, and the length of the time domain resource occupied by the CSI belongs to a fourth time domain length set, and it can be understood that the length of the time domain resource occupied by the CSI is less than the fourth time domain length. The third time domain length and the fourth time domain length are used as two threshold values, which may be specified by a protocol or preset by a network device and notified to a terminal device through a high-level signaling or a dynamic signaling.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the length of the time domain resource occupied by the CSI belongs to a third time domain length set, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to a first BLER to obtain the CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or the length of the time domain resource occupied by the CSI belongs to a fourth time domain length set, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to a second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Or, the length of the time domain resource occupied by the CSI belongs to at least one of a plurality of time domain length sets, where the plurality of time domain length sets include a third time domain length set and a fourth time domain length set, and then, in terms of describing the time domain length sets, the scheme of the embodiment C1 may also be described as follows: the CQI index corresponding to the CQI corresponding to the length of the time domain resource occupied by the CSI and included in the third time domain length set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the length of the time domain resource occupied by the CSI and included in the fourth time domain length set is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the length of the time domain resource occupied by the CSI and included in the third time domain length set is the first CQI index, and it should be understood that when the length of the time domain resource occupied by the CSI belongs to the third time domain length set, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the length of the time domain resource occupied by the CSI belongs to the third time domain length set or the fourth time domain length set, and therefore, the corresponding relationship between the length of the time domain resource occupied by the CSI and the CQI index, or the corresponding relationship between the time domain length set and the CQI index should be emphasized here, rather than the corresponding relationship between the length of the time domain resource occupied by the CSI (or the time domain length set) and the CQI index. For the understanding that the CQI index corresponding to the length of the time domain resource occupied by the CSI included in the fourth time domain length set is the second CQI index, the same holds.

It can be understood that, the shorter the time domain length of the resource where the CSI is located is, the more urgent the service is, such a service may be a URLLC service, or other more urgent services, and for such a service, a CQI table with a lower BLER or a higher BLER priority may be used to ensure reliability. If the longer the time domain length of the resource where the CSI is located is, the service is not very urgent, and the requirement of such service for reliability is generally not very high, then for such service, a CQI table with higher BLER or lower BLER priority may be used.

In this embodiment, the case of "equal to" is also presented, and similar to the embodiment a1, this embodiment is also only an example of dividing the case where the length of the time domain resource occupied by the CSI is equal to the third time domain length into the case where the length of the time domain resource occupied by the CSI is greater than the third time domain length, and the present embodiment is not limited to this in practice. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

C2, the first information includes the content of CSI.

In this embodiment, the terminal device determines the content of the CSI including the CQI, and thus determines the CQI index corresponding to the CQI according to the content of the CSI.

For example, the content of the CSI includes at least one of a plurality of contents including a first content and a second content.

Specifically, the content of the CSI is a first content, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the content of the CSI is a second content, and the terminal device determines that the CQI index corresponding to the CQI is the second CQI index. Or, the CSI content is a first content, and the CQI index corresponding to the CQI is a first CQI index, or the CSI content is a second content, and the CQI index corresponding to the CQI is a second CQI index.

As a first example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER, respectively. If the content of the CSI only comprises the CSI part1, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, the terminal equipment queries in the second CQI table to determine the CQI index corresponding to the CQI, or if the content of the CSI comprises the CSI part2, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain the CQI, and the terminal equipment queries in the first CQI table to determine the CQI index corresponding to the CQI.

Because the priority of CSI part1 is generally higher than that of CSI part2, if the CSI content only includes CSIpart1, it indicates that there may be more urgent traffic, such traffic may be URLLC traffic, or other more urgent traffic, for which a CQI table with lower BLER or higher BLER priority may be used to ensure reliability. If the CSI content includes CSI part2, indicating that the service is not critical and that the reliability requirements for such service are generally not high, then a CQI table with higher BLER or lower BLER priority may be used for such service.

As a second example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER, respectively. If the content of the CSI includes RSRP, and/or the content of the CSI includes PMI or RI, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or if the content of the CSI does not include RSRP, and/or the content of the CSI does not include PMI or RI, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Since RSRP, PMI and RI are slow contents, if the CSI includes these contents, it turns out that the CSI is not urgent for feedback, so a CQI table with higher BLER or lower priority of BLER may be employed.

As a third example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER, respectively. If the content of the CSI includes a sub-band CQI and/or a sub-band PMI, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain the CQI, the terminal equipment inquires in the first CQI table to determine a CQI index corresponding to the CQI, or if the content of the CSI only includes a broadband CQI and/or a broadband PMI, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Generally, the priority of wideband CSI is higher than that of sub-band CSI, if the content of CSI only includes wideband CQI and/or wideband PMI, it indicates that the service is urgent, and such service may be URLLC service or other urgent service, and for such service, a CQI table with low BLER or high BLER priority may be used to ensure reliability. If the content of the CSI includes sub-band CSI, indicating that the service is not very urgent, and the requirement for reliability of such service is not very high in general, then for such service, a CQI table with higher BLER or lower BLER priority may be used.

As a fourth example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER, respectively. If the number of antenna ports for which the content of the CSI is specific belongs to the first port number range, the terminal equipment determines to select a first CQI table, then performs measurement according to a first BLER to obtain a CQI, and the terminal equipment queries in the first CQI table to determine a CQI index corresponding to the CQI, or if the number of antenna ports for which the content of the CSI is specific belongs to the second port number range, the terminal equipment determines to select a second CQI table, then performs measurement according to a second BLER to obtain a CQI, and the terminal equipment queries in the second CQI table to determine the CQI index corresponding to the CQI.

The number of the antenna ports belongs to the range of the first number of ports, it can be understood that the number of the antenna ports is greater than or equal to the first number of ports, and the number of the antenna ports belongs to the range of the second number of ports, it can be understood that the number of the antenna ports is less than the second number of ports. The number of the first ports and the number of the second ports are used as two threshold values, which may be specified by a protocol or may be preset by a network device, and the two threshold values are notified to a terminal device through a high-level signaling or a dynamic signaling.

If the number of antenna ends targeted by the content of the CSI is more, the service is considered not to be urgent, because the calculation time is longer, a CQI table with lower BLER or lower BLER priority may be selected, and if the number of antenna ports targeted by the content of the CSI is more, the calculation time period is longer, the service may be considered to be urgent, and a CQI table with higher BLER or higher BLER priority may be selected.

Or, the content of the CSI includes at least one of a plurality of contents, and the plurality of contents includes the first content and the second content, then, from the perspective of describing the content of the CSI, the scheme of the embodiment C2 may also be described as: the CQI index corresponding to the CQI corresponding to the first content is a first CQI index, and the CQI index corresponding to the CQI corresponding to the second content is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the first content is a first CQI index, and it should be understood that when the content of the CSI is the first content, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the content of the CSI is the first content or the second content, and therefore, emphasis should be given here to the correspondence between the content of the CSI and the CQI index, not to the correspondence between the content of the CSI and the CQI index. For the understanding that the CQI index corresponding to the CQI corresponding to the second content is the second CQI index, the same is true.

In this embodiment, the case of "equal" is also divided, and similarly to the embodiment a1, the present embodiment is also only an example of dividing the case where the number of antenna ports is equal to the first number of ports into the same cases as the case where the number of antenna ports is greater than the first number of ports, and the present embodiment is not limited to this. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

C3, the first information includes the number of bits of the CSI.

In this embodiment, the terminal device determines the bit number of the CSI including the CQI, and thus determines the CQI index corresponding to the CQI according to the bit number of the CSI.

For example, the number of bits of the CSI belongs to at least one of a plurality of sets of bits, the plurality of sets of bits including a first set of bits and a second set of bits.

Specifically, the bit number of the CSI belongs to a first bit number set, and the terminal device determines that the CQI index corresponding to the CQI is the first CQI index, or the bit number of the CSI belongs to a second bit number set, and the terminal device determines that the CQI index corresponding to the CQI is the second CQI index. Or, the number of bits of the CSI belongs to a first set of bits and the CQI index corresponding to the CQI is a first CQI index, or the number of bits of the CSI belongs to a second set of bits and the CQI index corresponding to the CQI is a second CQI index.

The number of bits of the CSI belongs to a first set of bits, which may be understood as that the number of bits of the CSI is greater than or equal to a first threshold value, and the number of bits of the CSI belongs to a second set of bits, which may be understood as that the number of bits of the CSI is smaller than a second threshold value. The first bit threshold and the second bit threshold are used as two thresholds, which may be specified by a protocol or preset by a network device and notified to a terminal device through a high-level signaling or a dynamic signaling.

For example, there are 2 CQI tables, a first CQI table corresponding to the first BLER and a second CQI table corresponding to the second BLER. If the bit number corresponding to the content of the CSI is larger than or equal to the first bit threshold value, the terminal equipment determines to select a first CQI table, then the measurement is carried out according to the first BLER to obtain the CQI, the terminal equipment inquires in the first CQI table to determine the CQI index corresponding to the CQI, or if the bit number corresponding to the content of the CSI is smaller than the first bit threshold value, the terminal equipment determines to select a second CQI table, then the measurement is carried out according to the second BLER to obtain the CQI, and the terminal equipment inquires in the second CQI table to determine the CQI index corresponding to the CQI.

Or, the bit number of the CQI belongs to at least one of a plurality of bit number sets, and the plurality of bit number sets include a first bit number set and a second bit number set, so that from the viewpoint of describing the bit number sets, the scheme of embodiment C3 may also be described as: the CQI index corresponding to the CQI corresponding to the bit number of the CSI included in the first bit number set is a first CQI index, and the CQI index corresponding to the CQI corresponding to the bit number of the CSI included in the second bit number set is a second CQI index, wherein the first CQI index is different from the second CQI index.

Here, the CQI index corresponding to the CQI corresponding to the number of CSI bits included in the first bit number set is a first CQI index, and it is to be understood that when the number of CSI bits belongs to the first bit number set, the CQI index corresponding to the CQI is the first CQI index. The CQI is unchanged regardless of whether the CSI bit number belongs to the first set of bit numbers or the second set of bit numbers, and therefore, the correspondence between the CSI bit number and the CQI index should be emphasized here instead of the correspondence between the CSI bit number and the CQI index. For the above, the CQI index corresponding to the CQI corresponding to the bit number of the CSI included in the second bit number set is a second CQI index.

If the bit number corresponding to the content of the CSI is large, the service is considered not to be urgent, because the calculation time is long, a CQI table with a low BLER or a low BLER priority may be selected, and if the bit number corresponding to the content of the CSI is small, the calculation time period may be calculated, and if the service is considered to be urgent, a CQI table with a large BLER or a high BLER priority may be selected.

In this embodiment, the case of "equal to" is also divided, and similarly to the embodiment a1, this embodiment is also only an example of dividing the case where the number of bits of the CSI is equal to the first bit threshold value into the case where the number of bits of the CSI is greater than the first bit threshold value, and the present embodiment is not limited to this actually. For the description of the case of "equal to", reference may be made to embodiment a1, which is not repeated herein.

Any of the embodiments in the mode B and the mode C can also be applied in combination, or any of the embodiments in the mode a, the mode B, and the mode C can also be applied in combination.

The term "set" as used herein may also be understood as a "range", for example, the term "first set of values" may also be understood as a "first range of values", or the term "first set of time-domain lengths" may also be understood as a "first range of time-domain lengths", etc. In the "set", the included elements may be a continuous value range, or may also be at least one discrete value, and are not limited specifically.

If the system can support at least two CQI tables, the technical scheme provided by the embodiment of the application can flexibly indicate the specifically selected CQI table for the terminal equipment, so that the requirement of the URLLC service can be well adapted. In addition, the embodiment of the application can continue to use the existing CQI table, and the table itself does not need to be modified, thereby being beneficial to being compatible with the existing protocol.
