Description

Method and device for determining uplink control channel resources

Technical Field

The present application relates to the field of communications, and in particular, to a method and apparatus for determining uplink control channel resources.

Background

Currently, when a User Equipment (UE) is in a Radio Resource Control (RRC) connected state, a base station (gNode B, gNB) configures a plurality of PUCCH resource sets (PUCCH resource sets) for the UE, and each of the resource sets includes a plurality of PUCCH resources. The UE determines a resource set according to a range of a bit number of uplink information to be transmitted, and determines a specific resource for transmitting the uplink information according to a field of a PUCCH resource indicator field (PUCCH resource field) in DCI after receiving Downlink Control Information (DCI) for scheduling signaling.

However, in the process of sending the uplink control information to the base station, when resources carrying a hybrid automatic repeat request acknowledgement (HARQ-ACK) message and Channel State Information (CSI) overlap in a time domain, the terminal device may re-determine an uplink resource. How to ensure that the re-determined uplink resource can meet the relevant specification of the uplink control channel format and resource in one time slot of the protocol, the prior art has no relevant method. In addition, under the condition that the protocol constraint is not satisfied, no related scheme for re-determining the transmission resource exists in the prior art so as to further satisfy the transmission requirement of the terminal device.

Therefore, a method is needed to ensure that the base station and the terminal device can keep consistent in the process of determining the uplink resource, so as to improve the reliability of uplink transmission.

When the time unit has the time domain symbol number which is more than or equal to 4 and occupied by other symbols and/or the resource format is the resource of the second format, the related regulations of the uplink control channel format and the resource in one time slot in the protocol are met, so that the reliability of the uplink transmission of the terminal equipment and the base station is ensured.

With reference to the first aspect, in certain implementations of the first aspect, the first set of resources is configured for at least one of the first uplink information and the second uplink information.

The technical solution provided by the present application will be described in detail below with reference to the accompanying drawings.

In order to facilitate understanding of the embodiments of the present application, a brief description of several concepts involved in the present application is provided below.

1. Time slot and time domain symbol

A time slot may be understood as a portion of a serial self-multiplex of time slot information dedicated to a single channel. A time slot may be understood as a channel.

In the embodiments of the present application, the symbol is also referred to as a time domain symbol, and may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol, or a single carrier frequency division multiple access (SC-FDMA) symbol, where SC-FDMA is also referred to as an orthogonal frequency division multiplexing with transform precoding (OFDM with TP).

Furthermore, a time domain symbol may also be understood as a time unit, e.g., 1 time unit may be one or more subframes; alternatively, it may be one or more time slots; alternatively, it may be one or more symbols. When 1 time cell is a symbol, the time domain symbol and the time cell may be equivalent in the description of the embodiment of the present application.

2. Physical uplink channel

And the channel can be used for carrying uplink control information and/or uplink data. For example, the physical uplink channel may include a Physical Uplink Control Channel (PUCCH) defined in the LTE protocol or the NR protocol, a Physical Uplink Shared Channel (PUSCH), and other uplink channels having the above-described functions defined as the network evolves.

3. Downlink Control Information (DCI)

The method is mainly used for sending downlink scheduling assignment information, and has a plurality of different formats including, but not limited to, DCI format0-0, 0-1, 1-0, 1-1, 2-0, 2-1, 2-2, 2-3.

4. PUCCH resource indication field or PUCCH resource indicator field (PUCCH resource indicator field)

An information field of M bits (bit) in the DCI, configured to indicate a transmission resource available for HARQ-ACK information, where optionally, M is equal to 3.

Next, transmission target Uplink Control Information (UCI) according to the embodiment of the present application will be described in detail.

In this embodiment, the UCI includes at least one of a hybrid automatic repeat request acknowledgement (HARQ-ACK), a Scheduling Request (SR), and CSI (CQI, PMI, RI).

By way of example and not limitation, in the embodiments of the present application, the uplink control information may include, but is not limited to, one or more of the following information:

1. feedback information

In this embodiment, the uplink control information may include feedback information for downlink data.

Specifically, in the embodiment of the present application, the downlink data may be transmitted by using a feedback technique, which may include, by way of example and not limitation, a hybrid automatic repeat request (HARQ) technique.

The HARQ technology is a technology formed by combining Forward Error Correction (FEC) coding and automatic repeat request (ARQ).

For example, in the HARQ technology, after receiving data from a transmitting end, a receiving end may determine whether the data is accurately decoded. If the data cannot be accurately decoded, the receiving end can feed back non-acknowledgement (NACK) information to the sending end, so that the sending end can determine that the receiving end does not accurately receive the data based on the NACK information, and can perform retransmission processing; if the decoding can be accurately performed, the receiving end may feed back Acknowledgement (ACK) information to the sending end, so that the sending end may determine that the receiving end accurately receives data based on the ACK information, and may determine that data transmission is completed.

That is, in this embodiment of the present application, the receiving end may send ACK information to the sending end when decoding is successful, and may feed back NACK information to the sending end when decoding is failed

By way of example and not limitation, in the embodiment of the present application, the uplink control information may include ACK information or NACK information in the HARQ technology. The HARQ-ACK is used for feeding back the receiving condition of the downlink data channel PDSCH, and when the UE receives the downlink data channel PDSCH correctly, the UE sends an ACK. When the UE receives an error, a NACK may be sent. The base station determines the next scheduling strategy, such as retransmission or new transmission, according to the feedback information of the PDSCH channel by the UE.

It should be understood that the content included in the above-mentioned feedback information is only an exemplary illustration, and the present application is not limited thereto, and other information capable of indicating the receiving condition of the downlink data by the terminal device falls within the protection scope of the present application, for example, the feedback information may further include Discontinuous Transmission (DTX) information, and the DTX information may be used to indicate that the terminal device does not receive the downlink data.

2. Channel state information, CSI

In the field of wireless communication, CSI refers to channel properties of a communication link, and is channel state information fed back to a base station after a UE measures a channel state, and the information further includes information such as CQI/PMI/RI. It describes the fading condition of the signal on each transmission path, i.e. the value of each element in the channel gain matrix H, such as signal scattering (scattering), environmental fading (multipath fading), distance fading (power fading) and other information. The CSI may adapt the communication system to the current channel conditions, providing a guarantee for high reliability and high rate communication in a multi-antenna system.

3. Channel Quality Indicator (CQI) information

In the embodiment of the present application, the CQI may be used to reflect a channel quality of a Physical Downlink Shared Channel (PDSCH). The CQI is channel quality indication information for directly feeding back channel quality. The base station may further determine a Modulation Coding Scheme (MCS) used for transmitting data according to the CQI. When the value of the fed back CQI is high, a higher coding modulation mode and a higher code rate can be adopted, and more information can be borne on limited resources, so that the transmission rate of data is improved. When the value of the fed back CQI is lower, a lower coding modulation mode and a lower code rate can be adopted, and more time-frequency resources are adopted to transmit data, so that the reliability of data transmission is improved. Meanwhile, the UE enables the base station to schedule data on the frequency domain resources with good channel quality by measuring the CQI of different frequency domain resources, thereby obtaining the frequency domain scheduling gain.

By way of example and not limitation, in the embodiments of the present application, the channel quality of the PDSCH may be represented by 0 to 15. 0 indicates the worst channel quality and 15 indicates the best channel quality.

In this embodiment, the terminal device may send CQI information to the network device on a PUCCH or a Physical Uplink Shared Channel (PUSCH). For example, in this embodiment, the network device may determine Adaptive Modulation and Coding (AMC), a Modulation and Coding Scheme (MCS), a code rate or a data amount for uplink transmission or downlink transmission, and the like based on the CQI information.

4. Rank Indication (RI) information

In this embodiment, the RI is rank indication information, and is used to feed back the number of layers that can be separated from the channel to the base station, and the larger the number of layers is, the larger the amount of data that can be simultaneously transmitted is. The RI information may be used to indicate a valid number of data layers of the PDSCH, or in other words, the RI information may be used to indicate a number of Code Words (CWs) that the terminal device can currently support.

5. Precoding Matrix Indicator (PMI) information

In this embodiment of the present application, the PMI information may be used to indicate an index (index) of a codebook set, where the PMI is a precoding matrix identifier of transmission data that is fed back by the UE to the base station according to the measured channel quality. The base station may determine a corresponding precoding matrix according to the fed-back PMI information. That is, in the case of using a multi-antenna technology, for example, a multiple-input multiple-output (MIMO) technology, precoding processing (precoding) based on a precoding matrix is performed in baseband processing. The terminal device can indicate the precoding matrix through the PMI information, thereby being capable of improving the signal quality of the PDSCH.

In addition, there is some information such as resource indicator information (CRI) of CSI-RS for feeding back to the base station which measurement resource measures the best channel quality among the plurality of measurement resources measured.

It should be understood that the specific contents of the CSI listed above are only exemplary and should not be construed as limiting the present application in any way. The CSI sent by the receiving end device to the sending end device may include one or more items in the above list, or may further include other information used for characterizing the CSI besides the above list, which is not limited in this application.

In this embodiment of the present application, sending uplink control information may refer to sending data or information carried on an uplink control channel PUCCH or an uplink shared channel PUSCH, where the data or information may refer to data or information after being channel coded. This is not limited in this application.

Likewise, in this embodiment of the present application, sending downlink control information may refer to sending data or information carried on a downlink control channel PDCCH or a downlink shared channel PDSCH, where the data or information may refer to data or information after channel coding. This is not limited in this application.

Hereinafter, without loss of generality, the embodiments of the present application will be described in detail by taking an interaction process between a terminal device and a base station as an example. The terminal device may be any terminal device in a wireless communication system having a wireless connection relationship with one or more network devices. It is understood that any terminal device in the wireless communication system can implement wireless communication based on the same technical solution. This is not limited in this application.

In the 5G system, the format of the PUCCH and the corresponding rule are specifically shown in table 1 below. As can be seen from table 1 below, the resources of PUCCH format2, format 3, and format 4 may support hybrid transmission of HARQ, CSI, and SR. In the present application, the number of symbols included in the PUCCH is less than or equal to a preset constant N₁The number of included symbols is greater than or equal to a preset constant N₂The PUCCH resource of (2) is referred to as a short format PUCCH and is referred to as a long format PUCCH. Wherein N is₁、N₂Is a positive integer, N₁And N₂The numerical values of (A) may be the same or different.

It is to be understood that the predetermined constant N₁、N₂It may be a constant configured by higher layer signaling or a constant configured by physical layer signaling. In the embodiment of the present application, the higher layer signaling may be Radio Resource Control (RRC) signaling or MAC layer signaling; the physical layer signaling may be DCI. The present application does not limit the configuration of the preset constants.

For example, in 5G, N₁The value of (b) may be 2. The short-format PUCCH may refer to a PUCCH including 1 or 2 symbols, for example, PUCCH format2 and PUCCH format 0; n is a radical of₂The value of (3) may be 4, and the long format PUCCH may refer to a PUCCH including 4 to 14 symbols, for example, PUCCH format 1, format 3, format 4. In the embodiment of the present application, the PUCCH with the short format may be PUCCH format2, and the PUCCH with the long format may be PUCCH format 1, format 3, and format 4.

TABLE 1

In particular, the resources used for transmitting the HARQ-ACK are dynamically indicated by the base station. Firstly, a base station configures one or more resource sets (resource sets) for a terminal device, and the ranges of the number of UCI information bits carried by different resource sets are different. The base station and the terminal equipment determine a resource set from one or more resource sets (resource sets) according to the total bit number of the HARQ-ACK information required to be fed back by the terminal equipment, and then determine that one resource in the resource set carries the HARQ-ACK information according to a resource indicator field (resource indicator field) related to HARQ-ACK information feedback in a DCI signaling sent by the base station.

Fig. 2 is a schematic diagram of an example of a resource selection process in an uplink transmission process according to an embodiment of the present application. Specifically, in one time unit, the one PUCCH resource for carrying the HARQ-ACK determined by the base station may be a short format with the number of OFDM symbols being less than or equal to two symbols, for example, PUCCH format2, and the PUCCH for carrying CSI report #1 may be a short format, for example, PUCCH format 2. In this time unit, there may be an overlapping region in the time domain between the PUCCH resource carrying the HARQ-ACK information and the PUCCH resource carrying the CSI information, and it should be understood that the overlap may be partial overlap or full overlap. It should also be understood that a time unit here may be a slot or a window of time.

As shown in fig. 2, PUCCH format2 carrying HARQ-ACK information and PUCCH format2 carrying CSI report #1 have a partially overlapping region in the time domain. In this case, the base station may reselect a resource set according to the range of the information bit number in the resource set according to the total information bit number of the HARQ-ACK information and the CSI report that the terminal device needs to feed back and report, and determine a new PUCCH in the resource set reselected according to the resource indication field in the DCI signaling.

Or, as shown in fig. 3, in another example of a resource selection diagram of an uplink transmission process, when a PUCCH resource carrying HARQ-ACK information overlaps with a PUCCH carrying CSI information and a PUCCH carrying SR information in a time domain, a base station may reselect a resource set according to a total information bit number of the HARQ-ACK information, the CSI report, and the SR information that need to be fed back and reported, in the resource set, according to a range of the information bit number, and determine a new PUCCH in the newly selected resource set according to a resource indication field in the DCI signaling.

It should be understood that the base station reselects one resource set, which is referred to as a "first resource set" in this embodiment, and the first resource set may be an original resource set or another resource set that is newly selected, as long as the total number of bits of information for HARQ-ACK information and CSI report, or the total number of bits of information for HARQ-ACK information, CSI report, and SR information is guaranteed to be within the range of the number of bits of the first resource set.

For the above several possible cases, the new PUCCH newly determined by the base station and the terminal device may be a PUCCH long format of OFDM symbol number 4 to 14, such as PUCCH format 1, PUCCH format 3, and PUCCH format 4 listed above. However, if there is another PUCCH resource with 4 to 14 symbols in one slot, and the PUCCH does not overlap with the newly determined PUCCH resource for carrying HARQ-ACK and CSI information or the PUCCH resource for carrying HARQ-ACK, CSI, and SR in the time domain, two long format PUCCHs with 4 to 14 symbols cannot be transmitted in one slot as specified in the protocol. When two long-format PUCCHs of 4 to 14 symbols coexist in one slot, the terminal device and the base station cannot perform certain transmission, in other words, the behaviors of both the base station and the terminal device are uncertain. Therefore, there is a need for a method for determining resources, which can re-determine one PUCCH resource when the resources of PUCCH carrying HARQ-ACK and CSI information overlap in the time domain, or the resources of PUCCH carrying HARQ-ACK, CSI, and SR information overlap in the time domain, while avoiding the occurrence of two PUCCH with 4 to 14 symbols in one slot, thereby avoiding the uncertainty of transmission between the base station and the terminal device.

Fig. 4 is a schematic flow chart of an example method 400 for determining transmission resources according to an embodiment of the present application. The method 400 may be applied to the terminal device 102 or the terminal device 103 of the wireless communication system 100 described above. Fig. 5 is a schematic interaction diagram between a terminal device and a base station in this embodiment, which is described in detail below with reference to fig. 4 and 5.

As shown in fig. 5, the method 500 includes the following.

S501, in the first time slot, when the first uplink resource overlaps with the second uplink resource in the time domain, determining the first resource from the uplink resources whose number of ofdm symbols included in the first resource set is less than or equal to 2 according to a preset rule.

It should be understood that, here, the first uplink resource is used to carry first uplink information, the second uplink resource is used to carry second uplink information, the first uplink information and the second uplink information are any one of a hybrid automatic repeat request acknowledgement message HARQ-ACK and channel state information CSI, and any resource in the first set of resources is a resource configured for an uplink control channel.

For example, the first uplink resource may be an uplink control channel format PUCCH format2, and the second uplink resource may also be an uplink control channel format PUCCH format 2.

Optionally, the types of the first uplink information and the second uplink information may be the same or different.

Specifically, the first uplink information may be HARQ-ACK, the second uplink information may be CSI, and the case that the first uplink resource and the second uplink resource overlap in the time domain may be that the uplink resource for carrying the HARQ-ACK and the uplink resource for carrying the CSI completely overlap or partially overlap in the time domain.

Or, the first uplink information and the second uplink information may both be HARQ-ACKs, and the case that the first uplink resource and the second uplink resource overlap in the time domain may be that the uplink resources for carrying the two HARQ-ACKs are all overlapped or partially overlapped in the time domain.

Or, the first uplink information and the second uplink information may both be CSI, and the case that the first uplink resource and the second uplink resource overlap in the time domain may be that the uplink resources for carrying the two types of CSI completely overlap or partially overlap in the time domain.

Still alternatively, another possible case is included herein, that is, the uplink resources for carrying the HARQ-ACK, the uplink resources for carrying the CSI, and the uplink resources for carrying the SR are all overlapped or partially overlapped in the time domain. It should be understood that, in the above-mentioned cases where multiple uplink resources are completely overlapped or partially overlapped in the time domain, the technical solution provided by the present application may be used to determine the transmission resource between the base station and the terminal device, in other words, there may be more scenarios that may cause the base station and the terminal device to need to determine the uplink transmission resource, and as long as the technical solution provided by the embodiment of the present application is used to determine the transmission resource between the base station and the terminal device, the determination method and the terminal device fall within the protection scope of the present application.

It should also be understood that the "first resource set" in S501 may be an uplink resource set configured by the base station to the terminal device, for example, through higher layer signaling. Specifically, after the terminal device and the base station establish a communication connection, a resource is requested from the base station, the base station configures a plurality of uplink resource sets for the terminal device, each uplink resource set includes a plurality of PUCCH resources with different symbol numbers, such as long format PUCCH resources with different symbol numbers enumerated above, for example, PUCCH format 1, PUCCH format 3, PUCCH format 4; or a plurality of short format PUCCHs with different symbol numbers, such as PUCCH format 2.

Optionally, the first set of resources is configured for at least one of the first uplink information and the second uplink information.

Specifically, for the base station, the first set of resources may be determined according to at least one of the first uplink information and the second uplink information.

Accordingly, the terminal device may determine the first set of resources according to at least one of the first uplink information and the second uplink information. For example, the first set of resources is a set of resources determined according to the first uplink information; or the first resource set is a resource set determined according to the second uplink information; or the first resource set is a resource set determined according to the first uplink information and the second uplink information.

Specifically, in a plurality of resource sets configured by the base station for the terminal device, the base station needs to determine the first resource set according to the range to which the information bit number belongs. Specifically, the base station may determine the first resource set according to HARQ-ACK information to be fed back and reported; or re-determining the first resource set according to the HARQ-ACK information and the information bit number of the CSI report; or determining the first resource set according to the total information bit number of the HARQ-ACK information, the CSI report and the SR information.

Accordingly, the terminal device receives, from the base station, first indication information and second indication information, the first indication information being used for indicating a first uplink resource, the second indication information being used for indicating a second uplink resource, the first uplink resource being overlapped with the second uplink resource in a time domain, the first uplink resource corresponding to first uplink information, the second uplink resource corresponding to second uplink information, and the first uplink information and the second uplink information being any one of a hybrid automatic repeat request acknowledgement message HARQ-ACK and channel state information CSI.

It is to be understood that the first indication may comprise one or more indications and the second indication may comprise one or more indications. In the embodiments of the present application, it is often mentioned that the first uplink resource corresponds to the first uplink information, where "corresponding to" may be understood as "carrying", that is, the first uplink resource carries the first uplink information.

Fig. 6 is a schematic diagram of an example of a resource selection process provided in an embodiment of the present application, and details of a process of determining a PUCCH by a base station and a terminal device are described below with reference to fig. 6. It is assumed that there are three resources in a slot, namely PUCCH carrying CSI report #1, PUCCH carrying CSI report #2 and one PUCCH carrying HARQ-ACK information.

(1) The base station configures a plurality of uplink resource sets for the terminal device, such as resource set 1 and resource set 2 in fig. 6, where each uplink resource set includes a plurality of PUCCHs with different formats, and resource set 1 in the figure includes resource 1, resource 3, resource 5, resource 8, and the like, and each resource has a different format. Suppose that, at this time, the base station determines resource set 1 according to the bit number of the HARQ-ACK information to be transmitted, and informs the terminal device through DCI, and the terminal device determines resource 3 in resource set 1 according to the PUCCH resource indication field in DCI.

(2) When the resource of HARQ-ACK and the resource of CSI report #1 overlap in the time domain, or the resource of HARQ-ACK and the resource of CSI report #1 overlap in the time domain, and the PUCCH carrying CSI report #2 is a long-format PUCCH, the base station needs to reselect resource set 2 according to the HARQ-ACK information and the total number of bits of CSI report, and it should be understood that resource set 2 is the first resource set defined in this application.

(3) In order to avoid two long format PUCCHs in one slot, the terminal device selects a short format resource in resource set 2, such as resource 1 in fig. 6, where resource 1 may be PUCCH format 2.

(4) After the first resource set is determined, the base station and the terminal device determine the first resource from uplink resources, of which the number of orthogonal frequency division multiplexing symbols OFDM included in the first resource set is less than or equal to 2, according to a preset rule. For example, the base station and the terminal device may determine one PUCCH from among a plurality of short format PUCCHs different in symbol number, and as the first resource, the short format PUCCH may be PUCCH format 2.

It should be understood that, in the embodiment of the present application, the number of time domain symbols occupied by the first resource is less than or equal to 2; and/or the resource format of the first resource is the first format. The first format may be PUCCH format 2.

For convenience of description, a resource that includes the first set of resources and occupies a time domain symbol number that is less than or equal to 2 is referred to as a second resource, and then the first set of resources includes at least one second resource. In the following description, the second resource and the uplink resource with the symbol number less than or equal to 2 refer to short format resources defined in the present application, such as puchformat 2.

Several methods of how to select the first resource from the plurality of short-format PUCCHs are described below.

Method 1

The base station and the terminal device may determine the first resource according to the number of symbols of each uplink resource in the uplink resources of which the number of symbols is less than or equal to 2.

For example, the uplink resource with the largest number of symbols in the uplink resources with the number of symbols less than or equal to 2 is determined as the first resource. For example, for PUCCH format2, it is possible that the first PUCCH includes 1 symbol and the second PUCCH includes 2 symbols, and then the PUCCH with the largest number of symbols is selected as the first resource, i.e., the PUCCH including 2 symbols is selected.

When the first resource set comprises a plurality of uplink resources with the maximum number of symbols and the number of the symbols less than or equal to 2, determining the resource with the earliest or latest initial symbol in the uplink resources with the maximum number of symbols as the first resource; or determining the resource with the minimum number of Resource Blocks (RBs) occupied by the uplink resource with the maximum number of symbols as the first resource.

It should be understood that each uplink resource may occupy a certain time domain position and frequency domain position. In the time domain, the PUCCH includes different numbers of symbols, for example, the PUCCH in the short format may include 1 or 2 symbols; in the frequency domain, the number of RBs included in the PUCCH is different, for example, PUCCH format2 may include 1 to 16 RBs, which is the case where the time domain and frequency domain space occupied by the PUCCH is the smallest, and transmission resources can be saved by selecting the resource with the smallest number of RBs.

For example, when the second PUCCH includes 2 symbols and the third PUCCH also includes 2 symbols, the selection is performed according to the earliest or latest starting symbol of the PUCCH. Preferably, the PUCCH with the latest starting symbol is selected, so that the terminal device can have sufficient receiving time when receiving the message of the base station, and then performs HARQ-ACK feedback.

Optionally, when the first resource set includes a plurality of uplink resources whose starting symbols are the same and whose number of the symbols is less than or equal to 2, or the first resource set includes a plurality of uplink resources whose number of the symbols with the smallest number of RBs is less than or equal to 2, determining a resource whose resource index is the smallest among the plurality of uplink resources whose number of the symbols is less than or equal to 2 as the first resource.

Method two

The base station and the terminal device may determine, as the first resource, an uplink resource in which the number of symbols that is the same as the time domain length of the first uplink resource or the second uplink resource is less than or equal to 2.

When the first resource set includes a plurality of uplink resources whose number of symbols is equal to or less than 2 and whose time domain length is the same as that of the first uplink resource or the second uplink resource, determining, as the first resource, the earliest or latest resource of the initial symbols in the plurality of uplink resources whose number of symbols is equal to or less than 2 and whose time domain length is the same as that of the first uplink resource or the second uplink resource; or determining the resource with the least number of RBs occupied by the uplink resource of which the number of symbols is less than or equal to 2 and the time domain length of the first uplink resource or the second uplink resource is the same as the first uplink resource.

For example, when the first uplink resource is used for carrying HARQ-ACK and the second uplink resource is used for carrying CSI, the selection may be made in a short format resource with the same length as the resource carrying HARQ-ACK. When the selection mode is that there are still a plurality of short format resources in the first resource set, then selection is performed according to starting symbols of the short format resources, for example, the starting symbol is earliest or latest, where the resource with the latest starting symbol is a preferred resource, which can ensure that the terminal device has sufficient receiving time when receiving the message of the base station.

Method III

The base station and the terminal device may determine, as the first resource, an uplink resource in which the number of symbols with the lowest coding rate in the first resource set is less than or equal to 2.

When the first resource set includes a plurality of uplink resources with the lowest coding rate and the number of symbols less than or equal to 2, the method further includes:

determining the uplink resource of which the number of the earliest or latest initial symbols in the plurality of resources with the lowest coding rate is less than or equal to 2 as the first resource; and/or

And determining the uplink resource with the symbol number less than or equal to 2 and the resource block RB number which is the least in the plurality of resources with the lowest coding rate as the first resource.

Method IV

The base station and the terminal device may determine, as the first resource, a resource with the earliest or latest starting symbol in the uplink resources with the largest number of symbols; and/or determining the resource with the minimum number of Resource Blocks (RB) in the uplink resources with the maximum number of the symbols as the first resource.

When the first resource set includes a plurality of uplink resources with the same initial symbols and the number of the symbols being less than or equal to 2, or the first resource set includes a plurality of uplink resources with the minimum number of the symbols being less than or equal to 2, determining the resource with the minimum resource index among the plurality of uplink resources with the number of the symbols being less than or equal to 2 as the first resource.

Method five

The base station and the terminal device may determine, as the first resource, a resource with a smallest resource index among the plurality of uplink resources in which the number of symbols is less than or equal to 2.

It should be understood that the above listed rules for selecting uplink resources may be specified by a protocol, or may be configured for the base station and the terminal device through higher layer signaling, or the base station notifies the terminal device through physical layer signaling. In the embodiment of the present application, the higher layer signaling may be Radio Resource Control (RRC) signaling or MAC layer signaling.

It should be understood that the PUCCH in the first format is also referred to as a short-format PUCCH in this application, and the short-format PUCCH may refer to a PUCCH including 1 or 2 symbols, for example, PUCCH format2 and PUCCH format 0; the PUCCH in the second format is also referred to as a long-format PUCCH, and the long-format PUCCH may refer to a PUCCH including 4 to 14 symbols, for example, PUCCH format 1, format 3, and format 4.

S502, transmitting the first uplink information and the second uplink information through the first resource.

Specifically, the terminal device executes S420, and transmits the first uplink information and the second uplink information through the first resource. Accordingly, the base station receives the first uplink information and the second uplink information through the first resource.

In the transmission process of the HARQ-ACK and the CSI or the HARQ-ACK, the CSI and the RS, the base station and the terminal equipment can ensure the transmission reliability through the determined uplink resources.

In addition, when a third uplink resource and a fourth uplink resource exist in the first slot, the number of symbols included in the third uplink resource and the fourth uplink resource is greater than 4, and the third uplink resource and the fourth uplink resource do not overlap in the time domain, that is, it can be understood that two long format PUCCHs including 4 to 14 symbols, which do not overlap in the time domain, exist simultaneously in one slot, according to the requirement in the protocol, two long format PUCCHs including 4 to 14 symbols cannot be transmitted in one slot, and then the behaviors of the UE and the base station are uncertain.

Fig. 7 is a schematic interaction diagram of another resource determination method provided in an embodiment of the present application. The method 700 may be applied to the terminal device or the base station of the wireless communication system 100 described above. The method 700 comprises:

s701, discarding one of the third uplink resource and the fourth uplink resource according to a preset rule, where the number of symbols included in the third uplink resource and the fourth uplink resource is greater than 4.

Optionally, the third uplink resource is configured to carry third uplink information, the fourth uplink resource is configured to carry fourth uplink information, and the third uplink information and the fourth uplink information are HARQ-ACKs (hybrid automatic repeat request acknowledgement messages); or the third uplink information and the fourth uplink information are channel state information CSI; or the third uplink information and the fourth uplink information are at least two of HARQ-ACK, channel state information CSI and scheduling request SR.

Specifically, for example, in fig. 2, it is assumed that there are three resources in one slot, which are a PUCCH carrying CSI report #1, a PUCCH carrying CSI report #2, and a PUCCH carrying HARQ-ACK information, and the PUCCH carrying CSI report #2 is a long-format resource, such as PUCCH format 4; or in fig. 3, there are four resources, which are PUCCH carrying CSI report #1, PUCCH carrying CSI report #2, PUCCH carrying SR, and one PUCCH carrying HARQ-ACK information, respectively, and the PUCCH carrying CSI report #2 is a long-format resource, such as PUCCH format 4. If the new transmission resource determined by the terminal device according to the total bit number of the HARQ-ACK and the CSI or the total bit number of the HARQ-ACK, the CSI and the SR is a long-format PUCCH, such as any one of PUCCH format 1, PUCCH format 3 or PUCCH format 4, and the newly determined long-format PUCCH and PUCCH for carrying CSI report #2 do not overlap in time domain, then there are two long-format PUCCHs in the one slot.

In order to ensure the reliability of transmission, the terminal device may discard one of the long-format PUCCHs according to a certain rule, and only one long-format PUCCH is reserved in the slot.

In a possible implementation manner, the terminal device may discard the uplink resource carrying the uplink information of the first priority according to a preset priority order, and reserve the uplink resource carrying the uplink information of the second priority, where the second priority is higher than the first priority.

For example, if the priority of HARQ-ACK is higher than the priority of CSI, the uplink resource for carrying CSI may be discarded.

Or the priority of the HARQ-ACK is lower than that of the CSI, the uplink resource for carrying the HARQ-ACK can be discarded.

Or, if the priority of the CSI report #2 information is higher than that of the CSI report #1, the long format PUCCH for carrying the HARQ-ACK and the CSI report #1 is discarded.

Or, if the priority of the CSI report #2 information is lower than the priority of the HARQ-ACK and CSI report #1, the PUCCH with the long format for carrying CSI report #2 is discarded.

When the resource carrying the uplink information with low priority is discarded according to the priority of the uplink information, only one long-format PUCCH exists in the time slot.

S702, transmitting another resource which is not discarded in the third uplink resource and the fourth uplink resource.

And the terminal equipment sends the uplink information with high priority on the PUCCH which is not discarded, and correspondingly, the base station receives the PUCCH and acquires the uplink information with high priority.

By the technical scheme, the problem of transmission uncertainty caused by two long-format PUCCH resources appearing in one time slot can be avoided in the uplink transmission process between the terminal equipment and the base station.

Fig. 8 is a schematic diagram of another resource selection process provided in an embodiment of the present application. In the process of transmitting the uplink information, when resources of PUCCHs carrying HARQ-ACK and CSI information are overlapped in a time domain in the same time slot, or resources of PUCCHs carrying the information of HARQ-ACK, CSI and SR are overlapped in the time domain, and a new transmission resource determined according to the total bit number of the HARQ-ACK and CSI information, or the total bit number of the information of HARQ-ACK, CSI and SR is a long-format PUCCH. And another long-format PUCCH exists in the slot, so that the process of resource selection as shown in fig. 8 can be performed.

Specifically, in one slot, PUCCH format2 carrying HARQ-ACK and PUCCH format2 carrying CSI report #1 information overlap in the time domain, a new PUCCH resource is re-determined according to the total number of bits of HARQ-ACK and CSI report #1 information, and is the PUCCH in format 3, and if the PUCCH in format 3 and the PUCCH in format 4 carrying CSI report #2 do not overlap in the time domain, the two long format resources are discarded in the order of priority of the carried uplink information. In fig. 8, the priority of CSI report #1 is higher than that of CSI report #2, so that the PUCCH in format 4 for carrying CSI report #2 is discarded, thereby ensuring that only one long-format PUCCH is in the slot, and improving the reliability of transmission.
