Background technique

In the communication system, there are downlink transmission and uplink transmission, wherein the downlink transmission is the transmission from the network device to the terminal device, and the uplink transmission is the transmission from the terminal device to the network device. Due to the relatively high cost of network equipment, the coverage of downlink transmission is generally higher than that of uplink transmission. Therefore, Coverage Enhancement (CE) mainly focuses on how to improve the coverage of uplink transmission.

At present, the coverage of uplink transmission can be improved by increasing the repetition times of uplink transmission. Specifically, when the uplink transmission needs to be repeated, it is often judged whether the uplink transmission can be carried on the current time slot, which may cause the repetition times of the uplink transmission to be unsatisfactory.

In the P time slots, other dynamic information received is not expected to affect the transmission of the physical uplink channel, so that the influence of other dynamic information on the physical uplink channel transmitted in the P time slots can be avoided, and the repetition of the physical uplink channel is ensured The number of transmissions meets the requirements. In addition, the processing flow of the physical uplink channel is also simplified.

Exemplarily, when the symbol of the first time slot in the P time slots is replaced by other RRC information or other dynamic information Modification, in an implementation manner, when the first time slot cannot carry the physical uplink channel, the first time slot may not be counted in the count of repetitions of the physical uplink channel, and the physical The uplink channel may be delayed to the next time slot transmission of the first time slot in the P time slots. In another implementation manner, when some symbols in the first time slot cannot carry the physical uplink channel, the physical uplink channel may be transmitted on the symbols that can carry the physical uplink channel in the first time slot. In this way, the problem of insufficient time slots or symbols for carrying the physical uplink channel due to other RRC and/or other dynamic information can be avoided, that is, it is ensured that the number of repeated transmissions of the physical uplink channel meets the requirements.

Detailed ways

The technical solutions in the present application will be described below with reference to the accompanying drawings.

The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (wideband code division multiple access, WCDMA) system, general packet radio service (general packet radio service, GPRS), long term evolution (long term evolution, LTE) system, LTE frequency division duplex (frequency division duplex, FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, the future 5th Generation (5th Generation, 5G) system or new radio (NR), etc.

To facilitate understanding of the embodiments of the present application, a communication system applicable to the methods provided by the embodiments of the present application is first described in detail with reference to FIG. 1 . FIG. 1 shows a schematic diagram of a communication system 100 suitable for the method provided by this embodiment of the present application. As shown in the figure, the communication system 100 may include at least one network device, such as a base station (gNB) in a 5G system as shown in FIG. 1 ; the communication system 100 may also include at least one terminal device, as shown in FIG. 1 user equipment (UE) 1. Communication between the network device and the terminal device can be done through a wireless link. For example, the network device can send configuration information to the terminal device, and the terminal device can send uplink data to the network device based on the configuration information, that is, uplink transmission; for another example, the network device can send downlink data to the terminal device, that is, downlink transmission.

It should be understood that the network device in the communication system may be any device with a wireless transceiver function. The device includes but is not limited to: evolved Node B (evolved Node B, eNB), radio network controller (radio network controller, RNC), Node B (Node B, NB), base station controller (base station controller, BSC) , base transceiver station (base transceiver station, BTS), home base station (for example, home evolved nodeb, or home node b, HNB), baseband unit (baseband unit, BBU), wireless fidelity (wireless fidelity, WIFI) system Access point (AP), wireless relay node, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP), etc. It can also be 5G, such as NR , a gNB in the system, or, a transmission point (TRP or TP), one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or, it can also be a network node that constitutes a gNB or a transmission point, Such as baseband unit (BBU), or distributed unit (distributed unit, DU) and so on.

In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (active antenna unit, AAU for short). The CU implements some functions of the gNB, and the DU implements some functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer and the physical (PHY) layer. AAU implements some physical layer processing functions, radio frequency processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, therefore, in this architecture, the higher-layer signaling, such as the RRC layer signaling, can also be considered to be sent by the DU. , or, sent by DU+AAU. It can be understood that the network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, the CU can be divided into network devices in an access network (radio access network, RAN), and the CU can also be divided into network devices in a core network (core network, CN), which is not limited in this application.

The terminal device may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a wireless communication Functional handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in future 5G networks or future evolved public land mobile networks (PLMN) A terminal device, etc., is not limited in this embodiment of the present application.

It should also be understood that FIG. 1 is only a simplified schematic diagram for easy understanding, and the communication system 100 may also include other network devices or other terminal devices, which are not shown in FIG. 1 .

In the communication system 100, there are downlink transmission and uplink transmission. For example, the transmission from the gNB to the UE 1 shown in FIG. 1 is downlink transmission; the transmission from the UE 1 shown in FIG. 1 to the gNB is the downlink transmission. Due to the relatively high cost of network equipment, the coverage of downlink transmission is generally higher than that of uplink transmission. In addition, due to cost constraints on the UE side, a cheaper power amplifier is intelligently used, and its power upper limit is also lower than that on the gNB side. Therefore, coverage enhancement mainly focuses on how to improve the coverage of uplink transmission.

Uplink transmission includes physical uplink shared channel (PUSCH) transmission and physical uplink control channel (PUCCH) transmission. Among them, the coverage of PUCCH is relatively wide, and the amount of transmitted information is small, but the reliability of PUCCH is required to be high. PUSCH transmits a large amount of information and has relatively close coverage. Therefore, how to improve the coverage of uplink transmission is a more urgent problem. At present, the coverage of uplink transmission can be improved by repeating in the time domain, for example, the coverage of uplink transmission can be improved by increasing the number of repetitions and the way of repeating transmission.

At present, the network device schedules the network device to transmit PUSCH on consecutive time slots, which can be divided into two situations:

(1) High-level configuration (configured by higher layers) to transmit PUSCH

If the dynamic information (for example, Slot Format related Information (SFI)) indicates that at least part of the symbols in the symbols for scheduling the physical uplink channel are downlink symbols or flexible symbols; or if the dynamic information indicates that the symbols for scheduling the physical uplink channel are At least part of the symbols in the terminal equipment are used for the terminal equipment to receive the channel state information-reference Signal (CSI-RS) or the physical downlink shared channel (physical downlink shared channel, PDSCH), then on the at least part of the symbols PUSCH is not transmitted. In the remaining time slots, if there is a symbol in which the RRC information is configured as a downlink symbol in the symbols of the scheduled physical uplink channel, the transmission of the entire time slot is abandoned and counted in the count of the number of PUSCH repetitions.

(2) Dynamic information indicates the transmission of PUSCH

The terminal equipment does not expect the received dynamic information (such as SFI) to cause the PUSCH to fail to transmit. However, if there is a symbol in which the RRC information is configured as a downlink symbol in the symbols of the scheduled physical uplink channel, the transmission of the entire time slot is abandoned.

Wherein, as shown in Table 1, the symbol for scheduling the PUSCH may be indicated by the starting symbol (starting symbol) of the PUSCH, the symbol length (Length), and the possible value range of the starting symbol+symbol length.

As shown in Table 1, time slots for normal cyclic prefix (NCP) symbols and time slots for extended cyclic prefix (ECP) symbols are listed, in Type A (Type A) and Type B (Type B), an example of the start symbol of the scheduled physical uplink channel. Among them, S represents the start symbol, and L represents the symbol length.

Table 1

As can be seen from Table 1, S+L of Type A is less than or equal to 14 symbols, that is, one PUSCH transmission is limited to one time slot. Correspondingly, when Type A is configured for multiple transmissions, the terminal device will perform detection in each time slot in S+L. If it can be used to transmit PUSCH, one transmission of PUSCH can be performed, otherwise, this transmission is abandoned, or this transmission is abandoned on some symbols on the a-th time slot; and continue to see whether other time slots meet the conditions. Wherein, "available for" can be understood as the symbol is not occupied by other transmissions or the symbol is not a symbol used for downlink transmission.

At present, there are two ways to determine the time slot that can carry the uplink transmission. One way is to judge whether the uplink transmission can be carried on consecutive S time slots in turn according to the RRC information, where S is the configured repetition times. Another way is: according to the RRC and the dynamic information, it is judged whether the uplink transmission can be carried on successive S time slots in sequence. The dynamic information may include, but is not limited to, SFI, cancellation indication (cancellation indication) information, or transmission information for scheduling ultra-relaible and low latency communication (URLLC).

Both of these two methods need to determine the time slot that can carry the uplink transmission first, and then perform the uplink transmission on the time slot that can carry the uplink transmission, which may cause: the bth time slot in the S time slots can carry the Uplink transmission, however, the time slot that can carry uplink transmission is determined on the time slot after the bth time slot, so that the bth time slot that can be used for uplink transmission cannot be used for uplink transmission, resulting in the repetition of uplink transmission. The number of transmissions is not enough to meet the corresponding requirements.

Therefore, the embodiment of the present application provides a method for determining the transmission resources of the physical uplink channel. The method can determine the time slot carrying the physical uplink channel before the symbol or time slot of the physical uplink channel is transmitted for the first time, so as to ensure the physical uplink channel. The number of repeated transmissions of the channel satisfies the requirement.

The physical uplink channels involved in the embodiments of this application include PUCCH and/or PUSCH.

FIG. 2 provides a method 200 for determining a physical uplink channel transmission resource provided by an embodiment of the present application. The method 200 includes S210 and S220.

In some embodiments, the method 200 may be applied to a terminal device. In other embodiments, the method 200 may be applied to a communication apparatus that supports a terminal device to implement the method 200, for example, the communication apparatus includes a chip system.

Each step in the method 200 is described in detail below.

S210: Determine the first time according to the first information. The first information is used to indicate the transmission of the physical uplink channel, the first information is configured by higher layers or indicated by the first dynamic information, and the first time is earlier than the first symbol or time that bears the physical uplink channel. gap.

Exemplarily, if the first information is configured by a high layer, it may be understood that the first information is configured by a high layer of the terminal device. Alternatively, the fact that the first information is configured by a higher layer may be understood that the first information is configured by a higher layer of the network device, and the terminal device receives the first information sent by the network device through the higher layer.

Exemplarily, the first dynamic information may be downlink control information (downlink control information, DCI) format information (for example, a DCI format), uplink scheduling information of a random access response (Random Access Response, RAR) (for example, a RAR UL grant). ), the uplink scheduling information of the fallback random access response (such as fallback RAR UL grant) or the subsequent random access response information (such as success RAR).

Optionally, the first information may be obtained at or before the first moment.

In an example, the interval between the first moment and the start symbol of the first time slot carrying the physical uplink channel is N symbols, where N is a positive integer. For example, the first time slot carrying the physical uplink channel is the second time slot, and the starting symbol of the second time slot is the first symbol, then the difference between the first moment and the first symbol of the second time slot The interval between them is N symbols, so that the time slot carrying the physical uplink channel can be determined within a sufficient processing time before the first time slot carrying the physical uplink channel.

Exemplarily, N is determined according to at least one of the following: capability of the terminal device, subcarrier spacing, and RRC information.

For example, the capability of the terminal device is negatively correlated with N, that is, the stronger the capability of the terminal, the smaller N can be set. Therefore, according to the actual situation of the terminal device, N is set to ensure that the first time slot carrying the physical uplink channel is used. Previously, there was enough processing time to determine the time slot carrying the physical uplink channel.

For example, the subcarrier spacing can be positively correlated with N, that is, the larger the subcarrier spacing is, the larger N can be set. Therefore, setting N according to the actual situation ensures that before the first time slot carrying the physical uplink channel, there are Sufficient processing time to determine the time slot carrying the physical uplink channel.

In another example, the interval between the first moment and the first starting symbol carrying the physical uplink channel is M symbols, where M is a positive integer. For example, the first time slot that carries the physical uplink channel is the second time slot, and the fourth symbol on the second time slot is the first symbol that carries the physical uplink channel. The interval between the fourth symbols of the time slots is N symbols, so that the time slot carrying the physical uplink channel can be determined within a sufficient processing time before the first symbol carrying the physical uplink channel.

Exemplarily, M is determined according to at least one of the following: capability of the terminal device, subcarrier spacing, and RRC information.

For example, the capability of the terminal device has a negative correlation with M, that is, the stronger the capability of the terminal, the smaller M can be set. Therefore, according to the actual situation of the terminal device, M is set to ensure that before the first symbol carrying the physical uplink channel , there is enough processing time to determine the time slot carrying the physical uplink channel.

For example, the subcarrier spacing can be positively correlated with M, that is, the larger the subcarrier spacing is, the larger M can be set, so that M can be set according to the actual situation to ensure that there is enough space before the first symbol carrying the physical uplink channel. to determine the time slot carrying the physical uplink channel. S220: Send a physical uplink channel on at least one of the P time slots, where P is a positive integer, and the P time slots are determined according to the first RRC and/or the second dynamic information at the first moment, wherein the No. One RRC information is used to indicate all the symbols in the P time slots, and the second dynamic information is used to determine all the symbols or part of the symbols in the P time slots, and each symbol can be an uplink symbol, a downlink symbol or a flexible symbol.

The use of the first RRC information to indicate all symbols in the P time slots can be understood as: the first RRC information is used to indicate whether each symbol of all the symbols in the P time slots is an uplink symbol, a downlink symbol or a flexible symbol.

Exemplarily, the first RRC information may be time division duplex (time division dual, TDD) uplink (uplink, UL) and downlink (downlink, DL) common configuration (tdd-UL-DL-Configuration Common) information. Alternatively, the first RRC information may be time division duplex uplink and downlink dedicated configuration (tdd-UL-DL-Configuration Dedicated) information.

Optionally, the first RRC information may be received at or before the first moment.

The second dynamic information is used to determine all the symbols or part of the symbols in the P time slots can be understood as: the second dynamic information is used to determine the used symbols or part of the symbols in the P time slots. Symbols are also flexible symbols.

In one example, the second dynamic information may indicate data to be transmitted, and according to the second dynamic information, it may be determined whether the symbol of the data to be transmitted is an uplink symbol, a downlink symbol or a flexible symbol.

Exemplarily, the second dynamic information may include DCI format 2.0 (DCI format 2_0) information, DCI format information for instructing the UE to receive CSI-RS (a DCI format indicating to the UE to receive CSI-RS) or for indicating The UE receives the DCI format information of the PDSCH (a DCI format indicating to the UE to receive or PDSCH).

Optionally, the second dynamic information may be received at or before the first moment.

Traditional flexible symbols can be used as uplink symbols, downlink symbols, or symbols for switching between uplink and downlink transmissions. Exemplarily, if the flexible symbol is an uplink symbol or a downlink symbol, the symbol can also be used as an uplink symbol or a downlink symbol. If the flexible symbol is a symbol converted between uplink transmission and downlink transmission, the symbol cannot be used as a downlink symbol or an uplink symbol. However, the flexible symbols involved in the embodiments of the present application do not include symbols used for conversion between uplink transmission and downlink transmission.

Optionally, P is greater than or equal to S, and S is the number of repeated transmissions of the physical uplink channel indicated by the configuration information, or P is determined according to a time delay requirement.

Exemplarily, the configuration information may be RRC information or information configured by a higher layer.

Illustratively, the latency requirement may be configured by higher layers. Alternatively, the delay requirement can also be related to the traffic type of the data packet. For example, video data packets have higher latency requirements than audio data packets.

The determined number P of time slots for transmitting the physical uplink channel is greater than the configured number of times S of repeated transmission of the physical uplink channel. Exemplarily, when the symbol for scheduling the physical uplink channel on the first time slot of the P time slots is changed by other RRC information or other dynamic information, in an implementation manner, when the first time slot cannot carry the physical uplink channel, The first time slot may not be counted in the count of the repetition times of the physical uplink channel, and the physical uplink channel that should be transmitted on the first time slot may be postponed to the next time slot of the first time slot in the P time slots transmission. In another implementation manner, when some symbols in the first time slot cannot carry the physical uplink channel, the physical uplink channel may be transmitted on the symbols that can carry the physical uplink channel in the first time slot. In this way, the problem of insufficient time slots or symbols for carrying the physical uplink channel due to other RRC and/or other dynamic information can be avoided, that is, it is ensured that the number of repeated transmissions of the physical uplink channel meets the requirements.

Exemplarily, the determined number P of time slots for transmitting the physical uplink channel is greater than the configured number of times S of repeated transmission of the physical uplink channel, when the symbols for scheduling the physical uplink channel in the first S time slots in the P time slots are not When changed by other RRC information or other dynamic information, the remaining time slots (except the first S time slots) resources in the P time slots can be directly released, so that the remaining time slots can be used for other purposes.

Determining P according to the time delay requirement can avoid selecting the time slot beyond the time delay upper limit to transmit the physical uplink channel.

In some embodiments, the P time slots may also be determined according to the first RRC and/or the second dynamic information at any time before the first time.

Hereinafter, how to determine the P time slots will be described in detail by way of way A and way B. In mode A, the first information may be configured by the high layer, and the first information may also be indicated by the first dynamic information, that is, mode A is not only applicable to the scenario where the transmission of the PUSCH is configured by the high layer, but also applicable to the scenario where the transmission of the PUSCH is the first dynamic information. The scenario indicated by the information is not limited in this embodiment of the present application. In the way B, the first information is the first dynamic information indication, that is, the way B is only applicable to the scenario where the transmission PUSCH is the first dynamic information indication.

Manner A: at the first moment, according to the first RRC information and the second dynamic information, determine the first partial timeslot of the P timeslots; and/or, at the first moment, according to the first RRC information, determine the P timeslots the second part of the time slot.

In one example, within the validity period of the second dynamic information, the first partial timeslot of the P timeslots may be determined according to the first RRC information or the second dynamic information. Specifically, if the first RRC information or the second dynamic information indicates that the symbols for scheduling the physical uplink channel on the ith timeslot are all uplink symbols or flexible symbols, and the ith timeslot is within the time limit of the second dynamic information, Then the ith time slot may be a time slot in the first partial time slot.

Optionally, in the case where the first information is a high-level configuration, if the first RRC information or the second dynamic information indicates that the symbols for scheduling the physical uplink channel in the i-th time slot are all uplink symbols, and the i-th time slot If it is within the time limit of the second dynamic information, the i-th time slot may also be a time slot in the first partial time slot.

Optionally, the above i is greater than or equal to 1.

Optionally, when i takes multiple values, that is, the symbols of the physical uplink channel are scheduled on multiple time slots (for example, the first time slot, ..., the ith time slot) within the time period of the second dynamic information are all uplink symbols or flexible symbols, then the multiple timeslots may be multiple timeslots in the first part of the timeslots.

In addition to the time period of the second dynamic information, the second part of the time slots in the P time slots may be determined according to the first RRC information. Specifically, if the symbols for scheduling the physical uplink channel on the jth time slot outside the time limit of the second dynamic information indicated by the first RRC information are all uplink symbols or flexible symbols, and the jth time slot is located in the second dynamic information In addition to the time limit of , the j-th time slot may be a time slot in the second part of time slots.

According to the time limit of the second dynamic information, the P time slots that need to be determined are divided into a first part of time slots within the time limit of the second dynamic information and a second part of time slots not within the time limit of the second dynamic information, and then according to The first part of the time slot is determined by the first RRC information and the second dynamic information, and the second part of the time slot is determined according to the first RRC information, so that the obtained information can be fully used to determine the time slot that bears the physical uplink channel, and the time slot that bears the physical uplink channel can be improved. The accuracy of the time slot determination.

Optionally, in the case where the first information is configured by a high layer, if the first RRC information or the second dynamic information indicates that the symbols for scheduling the physical uplink channel on the jth time slot are all uplink symbols, and the jth time slot is an uplink symbol. If the slot is outside the time limit of the second dynamic information, the j-th time slot may also be a time slot in the second partial time slot.

Optionally, if the value of the above i is P, the above jth time slot does not exist, that is, the P time slots only include the first part of the time slots and do not include the second part of the time slots.

Optionally, when j takes multiple values, that is, the symbols of the physical uplink channel are scheduled on multiple time slots (for example, the first time slot, ..., the jth time slot) outside the time limit of the second dynamic information are all uplink symbols or flexible symbols, the multiple timeslots may be multiple timeslots in the second part of timeslots.

For example, as shown in FIG. 3 , the first time slot, the second time slot and the third time slot are within the time limit of the second dynamic information, and the fourth time slot is outside the time limit of the second dynamic information. The symbols for scheduling the physical uplink channel are the 9th symbol to the 14th symbol (for example, the bolded symbols shown in FIG. 3 ), wherein the symbol for scheduling the physical uplink channel may be the third dynamic channel described below. information or RRC information; the first RRC information indicates that all symbols on the first slot are downlink symbols, the first to tenth symbols on the second slot are flexible symbols, and the 11th to 14th symbols are uplink symbols symbol, all the symbols on the 3rd slot are uplink symbols, and all the symbols on the 4th slot are uplink symbols. The second dynamic information indicates that the 1st to 6th symbols on the 2nd time slot are downlink symbols, and the 7th to 10th symbols on the 4th time slot are flexible symbols.

After knowing whether the symbols for scheduling the physical uplink channel in the first to fourth time slots are uplink symbols, downlink symbols or flexible symbols, it is necessary to determine which time slots from the first time slot to the fourth time slot can be used. Bearing the physical uplink channel, that is, determining P time slots. Due to the limitation of the time limit of the second dynamic information, it is necessary to combine the time limit of the second dynamic information, and according to the acquired information, respectively determine the first part of the time slot within the time limit of the second dynamic information and the time slot not in the second dynamic information. The second partial timeslot within the time limit, the first partial timeslot and the second partial timeslot form P timeslots. The specific process is as follows:

Since the first time slot, the second time slot and the third time slot are within the time limit of the second dynamic information, the first to third time slots can be determined according to the first RRC information and the second dynamic information Whether there is the first part of the time slots in the P time slots. Specifically, in the first time slot, the second time slot and the third time slot, the first RRC information indicates that all symbols on the first time slot are downlink symbols, and the first RRC information indicates that the first time slot is a downlink symbol. The 9th and 10th symbols among the symbols (9th to 14th symbols) of the physical uplink channel scheduled on 2 time slots are flexible symbols, the 11th to 14th symbols are uplink symbols, and the first RRC The information indicates that the symbols (the 9th to 14th symbols) for scheduling the physical uplink channel on the third time slot are uplink symbols, so the second time slot and the third time slot are both in the first part of the time slot. a time slot.

Since the fourth time slot is outside the time limit of the second dynamic information, it may be determined whether the fourth time slot is the second partial time slot in the P time slots only according to the first RRC information. Specifically, in the fourth time slot, the first RRC information indicates that the symbols (the ninth to the fourteenth symbols) for scheduling the physical uplink channel in the fourth time slot are all uplink symbols. Therefore, the fourth time slot The slot is one of the second partial slots.

Therefore, among the four time slots shown in FIG. 3 , the second time slot, the third time slot and the fourth time slot may be time slots among the P time slots, that is, P=3. And the second time slot and the third time slot are time slots in the first partial time slot, and the fourth time slot is a time slot in the second partial time slot.

At this time, if the number of times of repeated transmission of the configured physical uplink channel is S=2, then when the second time slot in the P time slots is scheduled for the first time slot in the symbols (the ninth to the fourteenth symbols) of the physical uplink channel When 9 symbols are changed to downlink symbols by other RRC information or other dynamic information, at this time, the second time slot can be excluded from the count of repetitions of the physical uplink channel, and the second time slot should have been transmitted. The physical uplink channel can be delayed to the next time slot (the third time slot) of the second time slot in the P time slots for transmission, so as to avoid the transmission of the physical uplink channel due to other RRC and/or other dynamic information. The problem of insufficient time slots (3) ensures that the number of repeated transmissions of the physical uplink channel meets the requirements.

If the configured number of repeated transmissions of the physical uplink channel is S=2, when the symbols for scheduling the physical uplink channel in the first two time slots (the second time slot and the third time slot) in the P time slots are not used by other When the RRC information or other dynamic information is changed, that is, when the physical uplink channel is transmitted in the 2nd and 3rd timeslots respectively, the resources of the 4th timeslot are directly released, so that the 4th timeslot can be used for other purposes .

The symbols for scheduling the physical uplink channels involved in the embodiments of the present application may be understood as scheduling symbols for carrying physical uplink channel transmissions, rather than symbols carrying scheduling information, which is used to indicate transmission of the physical uplink channels. For example, the scheduling information may be the first information.

In some embodiments, the symbol for scheduling the physical uplink channel involved in the embodiment of the present application may be indicated by the third dynamic information. For example, as shown in FIG. 3 , the third dynamic information indicates that the symbols for scheduling the physical uplink channel are the 9th symbol to the 14th symbol.

Exemplarily, the third dynamic information may include DCI format information (such as a DCI format), uplink scheduling information of the RAR (such as a RAR UL grant), and uplink scheduling information of a fallback random access response (such as fallback RAR UL grant). ), subsequent random access response information (such as success RAR), DCI format 2_0 information, CSI-RS DCI format information (a DCI format indicating to the UE to receiving CSI-RS) or DCI used to instruct the UE to receive PDSCH Format information (a DCI format indicating to the UE to receive or PDSCH).

In other embodiments, the symbols for scheduling physical uplink channels involved in the embodiments of the present application may be indicated by RRC information. For example, the RRC information may indicate the starting symbol (starting symbol) and the symbol length (Length) of the scheduled physical uplink channel.

In one example, the RRC information includes a start symbol identifier (eg, S), a symbol identifier corresponding to the start identifier, a length identifier (eg, L), and a symbol identifier corresponding to the length identifier. Optionally, the symbol identification may be the number of the symbol.

In another example, the RRC information may indicate a starting symbol (starting symbol) and a length (Length) of the scheduled physical uplink channel through a table (for example, the form of Table 1 may be referred to).

Manner B, at the first moment, according to the first RRC information and the second dynamic information, determine the third partial timeslot of the P timeslots; and/or, at the first moment, according to the first RRC information and the preset dynamic information A fourth partial slot of the P slots is determined.

In one example, within the validity period of the second dynamic information, the third partial timeslot of the P timeslots may be determined according to the first RRC information or the second dynamic information. Specifically, if the first RRC information or the second dynamic information indicates that the symbols for scheduling the physical uplink channel on the mth time slot are all uplink symbols or flexible symbols, and the mth time slot is within the time limit of the second dynamic information, Then the mth time slot may be a time slot in the third partial time slot.

Optionally, the above m is greater than or equal to 1.

Optionally, when m takes multiple values, that is, the symbols of the physical uplink channel are scheduled on multiple time slots (for example, the first time slot, ..., the mth time slot) within the time period of the second dynamic information are all uplink symbols or flexible symbols, then the multiple timeslots may be multiple timeslots in the third partial timeslot.

In addition to the time period of the second dynamic information, the fourth part of the time slots in the P time slots may be determined according to the first RRC information and the preset dynamic information. Specifically, if the first RRC information or the preset dynamic information indicates that the symbols for scheduling the physical uplink channel on the nth time slot are all uplink symbols or flexible symbols, and the nth time slot is outside the time limit of the second dynamic information, Then the n th time slot may be a time slot in the fourth partial time slot.

According to the time limit of the second dynamic information, the P time slots to be determined are divided into a third part of time slots within the time limit of the second dynamic information and a fourth part of time slots not within the time limit of the second dynamic information, and further The third part of the time slot is determined according to the first RRC information and the second dynamic information, and the fourth part of the time slot is determined according to the first RRC information and the preset dynamic information, so that the obtained information can be fully utilized to determine the time slot carrying the physical uplink channel , to improve the accuracy of determining the time slot carrying the physical uplink channel.

In addition, in addition to the time period of the second dynamic information, compared with the method A, the method B not only uses the first RRC information, but also uses the preset dynamic information to determine the time slot that bears the physical uplink channel, so as to better The accuracy of determining the time slot carrying the physical uplink channel is improved.

Optionally, if the value of m above is P, the nth timeslot does not exist, that is, the P timeslots only include the third partial timeslot and do not include the fourth partial timeslot.

Optionally, when n takes multiple values, that is, the symbols of the physical uplink channel are scheduled on multiple time slots (for example, the first time slot, ..., the nth time slot) beyond the time limit of the second dynamic information are all uplink symbols or flexible symbols, then the multiple timeslots may be multiple timeslots in the fourth partial timeslot.

In one example, the time period of the second dynamic information is the monitoring period of the search space. For example, as shown in FIG. 4 , the detection period of the search space is the time between t1 and t2, and the aging of the second dynamic information is the time between t1 and t2.

In another example, the aging time of the second dynamic information is the time between the start time of the monitoring period of the search space and the end time of the monitoring of the second dynamic information. For example, as shown in FIG. 5 , the detection period of the search space is the time between t1 and t2, the second dynamic information monitoring end time is t3, and the aging of the second dynamic information is the time between t1 and t3.

In some embodiments, the preset dynamic information may be determined according to the second dynamic information.

In an example, if the second dynamic information is configured periodically, and the network device generally does not change the configuration parameters indicated by the second dynamic information, the preset dynamic information may be determined according to the second dynamic information. For example, the configuration parameter of the preset dynamic information may be set as the configuration parameter indicated by the second dynamic information, the aging time of the preset dynamic information may be set as the aging time of the second dynamic information, and the starting time of the preset dynamic information aging may be set as the second dynamic information aging time. The end time of the dynamic information aging (for example, the time t2 shown in FIG. 4 ) or the start time of the detection period of the first search space after the end time of the second dynamic information aging (for example, as shown in FIG. 5 ) time t4).

Optionally, if the preset time limit of the dynamic information is the start time of the detection period of the first search space after the end time of the second dynamic information time limit, it may exist outside the time limit of the second dynamic information and in the pre-set time. Assuming an out-of-time time slot of the dynamic information, this part of the time slot can determine whether there is a fifth part of the time slot in the P time slots according to the first RRC.

For example, as shown in FIG. 6, the monitoring period of the search space is three time slots. If the aging time of the second dynamic information is the monitoring period of the search space, then the aging time of the second dynamic information is the time between the time t1 and the time t2, and the aging time of the preset dynamic information is the time between the time t2 and the end time of the sixth time slot. time (not shown in Figure 6). Therefore, the first time slot, the second time slot and the third time slot are within the time limit of the second dynamic information, and the fourth time slot and the fifth time slot are outside the time limit of the second dynamic information, and are within the time limit of the second dynamic information. Set the time limit of dynamic information.

The symbols for scheduling the physical uplink channel are the 9th symbol to the 14th symbol, where the symbol for scheduling the physical uplink channel may be the third dynamic information or RRC information described above; the first RRC information indicates the first time slot All symbols above are downlink symbols, all symbols in the second slot are flexible symbols, the first to sixth symbols in the third slot are downlink symbols, and the seventh to 14th symbols are flexible symbols , all symbols on the 4th time slot are uplink symbols, and all symbols on the 5th time slot are flexible symbols. The second dynamic information indicates that all symbols in the second time slot are downlink symbols, the 11th to 14th symbols in the third time slot are uplink symbols, and all symbols in the fifth time slot are uplink symbols .

After knowing whether the symbols for scheduling the physical uplink channel in the first to fifth time slots are uplink symbols, downlink symbols or flexible symbols, it is necessary to determine which time slots from the first time slot to the fifth time slot can be used. Bearing the physical uplink channel, that is, determining P time slots. Due to the limitation of the time limit of the second dynamic information, it is necessary to combine the time limit of the second dynamic information, and according to the acquired information, respectively determine the third part of the time slot that is within the time limit of the second dynamic information and the third part of the time slot that is not within the time limit of the second dynamic information. The fourth partial timeslot within the time limit of , the third partial timeslot and the fourth partial timeslot form P timeslots. The specific process is as follows:

Since the first time slot, the second time slot and the third time slot are within the time limit of the second dynamic information, the first to third time slots can be determined according to the first RRC information and the second dynamic information Whether there is a third partial slot in the P slots. Specifically, in the first time slot, the second time slot and the third time slot, the first RRC information indicates that all symbols on the first time slot are downlink symbols, and the second dynamic information indicates that the second time slot is a downlink symbol. All symbols in the first time slot are downlink symbols, and the first RRC information indicates that the ninth and tenth symbols among the symbols (the ninth to 14th symbols) of the physical uplink channel scheduling in the third time slot are flexible symbol, and the second dynamic information indicates that the 11th to 14th symbols in the symbols (9th to 14th symbols) for scheduling the physical uplink channel on the 3rd time slot are uplink symbols, therefore, the 3rd time slot Both are one time slot in the third partial time slot.

Since the fourth time slot and the fifth time slot are outside the time limit of the second dynamic information and within the time limit of the preset dynamic information, the fourth time slot can be determined according to the first RRC information and the preset dynamic information Whether there is a fourth partial time slot in P time slots. Specifically, in the 4th time slot and the 5th time slot, the first RRC information indicates that the symbols (the 9th to 14th symbols) of the scheduled physical uplink channel on the 4th time slot are uplink symbols, and the first The RRC information indicates that the symbols (the ninth to 14th symbols) for scheduling the physical uplink channel on the fifth time slot are flexible symbols, and the preset dynamic information indicates that the symbols for scheduling the physical uplink channel on the fifth time slot (the ninth to the fourteenth symbols) are flexible symbols. to the 14th symbol) are uplink symbols, therefore, the 4th time slot and the 5th time slot are one time slot in the fourth partial time slot.

Therefore, among the 4 time slots shown in FIG. 6 , the 3rd time slot, the 4th time slot and the 5th time slot may be time slots among the P time slots, that is, P=3. And the third time slot is a time slot in the third partial time slot, and the fourth time slot and the fifth time slot are time slots in the fourth partial time slot.

At this time, if the number of times of repeated transmission of the configured physical uplink channel is S=2, then when the third time slot in the P time slots is scheduled for the symbols (9th to 14th symbols) of the physical uplink channel, the first When 9 symbols are changed to downlink symbols by other RRC information or other dynamic information, at this time, the third time slot can be excluded from the count of repetitions of the physical uplink channel, and the third time slot should have been transmitted. The physical uplink channel can be delayed to the next time slot (the fourth time slot) of the third time slot in the P time slots for transmission, so as to avoid the transmission of the physical uplink channel due to other RRC and/or other dynamic information. The problem of insufficient time slots (2) ensures that the number of repeated transmissions of the physical uplink channel meets the requirements.

At this time, if the delay requirement is within the first time slot to the fourth time slot, in order to meet the delay requirement, it is possible to avoid selecting the time slot beyond the upper limit of the time delay to transmit the physical uplink channel, that is, in the fifth time slot The physical uplink channel is not transmitted on the

For another example, as shown in FIG. 6 , the monitoring period of the search space is three time slots. If the aging time of the second dynamic information is the time between the start time of the monitoring period of the search space and the end time of monitoring the second dynamic information, that is, the aging time of the second dynamic information is the time between time t1 and time t3. The preset start time of the aging of the dynamic information is time t4. The first time slot, the second time slot, the third time slot and the fourth time slot are within the time limit of the second dynamic information, and the fifth time slot is outside the time limit of the second dynamic information and within the preset dynamic information out of time limit.

The symbols for scheduling the physical uplink channel are the 9th symbol to the 14th symbol, where the symbol for scheduling the physical uplink channel may be the third dynamic information or RRC information described above; the first RRC information indicates the first time slot All symbols above are downlink symbols, all symbols in the second slot are flexible symbols, the first to sixth symbols in the third slot are downlink symbols, and the seventh to tenth symbols are Flexible symbols, all symbols in the fourth time slot are uplink symbols, and all symbols in the fifth time slot are flexible symbols. The second dynamic information indicates that all symbols in the second time slot are downlink symbols, the 11th to 14th symbols in the third time slot are uplink symbols, and all symbols in the fifth time slot are uplink symbols .

After knowing whether the symbols for scheduling the physical uplink channel in the first to fifth time slots are uplink symbols, downlink symbols or flexible symbols, it is necessary to determine which time slots from the first time slot to the fifth time slot can be used. Bearing the physical uplink channel, that is, determining P time slots. Due to the limitation of the time limit of the second dynamic information and the preset dynamic time limit, it is necessary to combine the time limit of the second dynamic information and the preset dynamic information time limit, and according to the acquired information, respectively determine the time limit within the time limit of the second dynamic information. The third partial time slot, the fourth partial time slot that is not within the time limit of the second dynamic information but within the preset dynamic time limit, and/or the first time slot that is not within the time limit of the second dynamic information nor within the preset dynamic time limit Five partial time slots, the third partial time slot, the fourth partial time slot and the fifth partial time slot constitute P time slots. The specific process is as follows:

Since the first time slot, the second time slot, the third time slot and the fourth time slot are within the time period of the second dynamic information, the first to second time slots can be determined according to the first RRC information and the second dynamic information Whether there is a third part of the P slots in the 4th slot. Specifically, from the first time slot to the fourth time slot, the first RRC information indicates that all symbols in the first time slot are downlink symbols, and the second dynamic information indicates that all symbols in the second time slot are downlink symbols. The symbols are downlink symbols, and the first RRC information indicates that the ninth and tenth symbols among the symbols (the ninth to the fourteenth symbols) of the physical uplink channel scheduled on the third time slot are flexible symbols, and the second The dynamic information indicates that the 11th to 14th symbols in the symbols (9th to 14th symbols) of the physical uplink channel scheduled on the 3rd time slot are uplink symbols, and the first RRC information indicates that the 4th time The symbols (the 9th to 14th symbols) for scheduling the physical uplink channel on the slot are all uplink symbols. Therefore, the third time slot and the fourth time slot are both a time slot in the third partial time slot.

Since the fifth time slot is outside the time limit of the second dynamic information and outside the time limit of the preset dynamic information, it can be determined whether the fifth time slot is the fifth time slot among the P time slots only according to the first RRC information Partial time slot. Specifically, in the fifth time slot, the first RRC information indicates that the symbols (the ninth to 14th symbols) for scheduling the physical uplink channel on the fifth time slot are flexible symbols. Therefore, the fifth time slot can is one of the fifth partial time slots.

Therefore, among the 4 time slots shown in FIG. 6 , the 3rd time slot, the 4th time slot and the 5th time slot may be time slots among the P time slots, that is, P=3. And the third time slot and the fourth time slot are one time slot in the third partial time slot, the fifth time slot is one time slot in the fifth partial time slot, and there is no fourth partial time slot.

At this time, if the number of times of repeated transmission of the configured physical uplink channel is S=3, the physical uplink channel can be transmitted in the third time slot to the fifth time slot in the P time slots.

At this time, if the time delay requirement is within the first time slot to the third time slot, in order to meet the time delay requirement, it is possible to avoid selecting the time slot beyond the time delay upper limit to transmit the physical uplink channel, that is, in the fourth time slot And the physical uplink channel is not transmitted on the fifth time slot.

The above content details how the P time slots are determined. The following describes in detail how to transmit the physical uplink channel on at least one of the P time slots.

In addition, the P time slots described below may be determined by the foregoing method 200, or may be determined by other methods, which are not limited in this embodiment of the present application.

In some embodiments, over the P time slots, other dynamic information that is not expected to be received affects the transmission of the physical uplink channel.

In an example, other dynamic information that is not expected to affect the transmission of the physical uplink channel can be understood as: in the P time slots, the terminal device can receive other dynamic information, but the received other dynamic information will not Affects the transmission of the physical uplink channel on the P time slots. Specifically, other dynamic information received will not modify the symbols for scheduling the physical uplink channel in the P time slots to be downlink symbols or flexible symbols used for downlink and uplink conversion, thereby It will not affect the terminal equipment to send the physical uplink channel on the P time slots.

At this time, on each of the P time slots, the physical uplink channel is transmitted. In other embodiments, if the symbol for scheduling the physical uplink channel on the Qth time slot in at least one time slot of the P time slots determined by the terminal device includes a downlink symbol (for example, indicated by other RRC information or dynamic information) is a downlink symbol or scheduled for downlink transmission) and/or a symbol used for switching between uplink and downlink transmission (e.g., indicated by other RRC information or dynamic information or scheduled as a symbol used for switching between uplink and downlink transmissions) ), then on the Qth time slot, the physical uplink channel is not sent; or, in the symbols for scheduling the physical uplink channel on the Qth time slot, the downlink symbols and/or the symbols used for the conversion between uplink transmission and downlink transmission are removed. On symbols other than the symbol, the physical uplink channel is sent. Optionally, the other symbols may include symbols carrying a demodulation reference signal (DMRS).

Wherein, for example, the dynamic information may be SFI, or the dynamic information may be dynamic information indicating that the UE receives CSI-RS or PDSCH.

For example, if the symbols of the scheduled physical uplink channel are the 1st to 10th symbols, the 1st to 4th symbols of the Qth time slot in the P time slots are flexible symbols, and the 5th to 4th symbols are flexible symbols. The 14th symbol is an uplink symbol. When the first symbol and the second symbol in the Qth time slot are scheduled as downlink symbols by other RRC information or dynamic information, in the Qth time slot, no physical uplink channel is sent, or, in the Qth time slot On the 1st to 10th time slot, the symbols other than the downlink symbol (the 1st symbol and the 2nd symbol) and the symbol used for the conversion between uplink transmission and downlink transmission (the 3rd symbol) in the 1st to 10th symbols (4th symbol to 10th symbol), the physical uplink channel is sent. For example, if the first symbol in the Qth time slot is scheduled as a symbol carrying DMRS by other RRC information or dynamic information, the physical uplink channel may be sent on the first symbol in the Qth time slot. Wherein, the symbol bearing the DMRS may be determined by the symbol indicated by the position of the DMRS type A (dmrs-TypeA-Position).

Optionally, the above-mentioned Q is greater than or equal to 0.

Optionally, in some embodiments, it is not expected to receive dynamic information for changing the physical uplink channel transmission after the first time instant.

In one example, after the first time instant, the dynamic information received by the terminal device does not change the transmission of the physical uplink channel. For example, if the second dynamic information does not affect the transmission of the physical uplink channel on the determined P time slots, the terminal device may receive the second dynamic information again.

Optionally, in some other embodiments, from the first moment to the moment when the expiration of the second dynamic information expires, it is not expected to receive dynamic information for changing the transmission of the physical uplink channel. That is, the terminal device only needs to not expect to receive the dynamic information for changing the physical uplink channel transmission from the first time to the time when the time limit of the second dynamic information expires. It is not expected to receive dynamic information for changing physical upstream channel transmissions.
