Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a configuration method, apparatus, device, and storage medium. Background Art

[0002] Currently, in the case of communication between only a single user equipment (UE) and a base station, for the uplink transmission of the UE, when a conflict occurs between the transmission of a physical uplink shared channel (PUSCH) and other channels or signals, the first solution is that for a PUSCH with a priority index of 0, the network only configures the transmission of a sounding reference signal (SRS) after the time-domain position of the PUSCH transmission; the second solution is that for a PUSCH with a priority index of 1 or a physical uplink control channel (PUCCH) with a priority index of 0, when the SRS conflicts with the PUSCH or PUCCH, the SRS is dropped; the third solution is that the base station scheduling ensures that the PUSCH does not conflict with the physical random access channel (PRACH). However, in the scenario of joint PUSCH transmission for multiple UEs, if a conflict occurs between the PUSCH of a certain UE and the transmission of other channels or signals, there is currently no solution for conflict resolution.

In this way, UE2 will not map the PUSCH to this time-frequency resource position, but only transmit the PUSCH at the time-frequency resource positions where the PUSCH can be mapped, thereby achieving conflict resolution.

[0097] Before introducing the technical solution of the embodiment of the present application, the related technologies will be introduced first.

[0098] Currently, for the new scenario of PUSCH joint transmission for multiple UEs, it includes: the first scenario, if the channel state of one terminal deteriorates, another terminal can be used to assist in data transmission to make up for the unstable service performance caused by the change of the channel state, improve the throughput and reliability, and at the same time reduce the service delay. The second scenario, when the UE is limited by the uplink (UL, UpLink) transmission power and cannot meet the rate requirement, especially for the cell-edge UE, another terminal can be used to assist in data transmission to improve the data transmission throughput. The third scenario, when the UE has a large throughput requirement for the uplink, but the number of antennas of the UE is small, it can perform multi-antenna joint transmission on the uplink with other UEs to increase the number of uplink transmission streams.

[0099] For PUSCH joint transmission, taking 2 UEs as an example, the 2 UEs can adopt the single-frequency network (SFN, Single Frequency Network) method or space division multiplexing (SDM, Space Division Multiplexing) or coherent joint transmission (CJT, Coherent Joint Transmission) method. To ensure the reception and demodulation performance at the base station side, these two transmission methods require that the time-frequency resources occupied by the PUSCHs sent by the 2 UEs are exactly the same. When multiplexing the PUSCH with the uplink control information (UCI, Uplink Control Information), it is required that the content carried by the transport block (TB, Transport Block) transmitted on the PUSCHs sent by the 2 UEs, that is, the UCI, is exactly the same. For the uplink transmission of each terminal, there are uplink channels or signals such as PUSCH, PUCCH, PRACH, and SRS. To ensure that the time-frequency resources of the PUSCHs sent by the 2 UEs and the content carried by the transmitted TB are exactly the same, the following possible problems need to be solved:

[0100] First, when the time-frequency resource position of the PUSCH of one of the UEs cannot transmit the PUSCH due to a conflict with the SRS, how to ensure that the time-frequency resources occupied by the PUSCHs sent by the 2 UEs are exactly the same.

[0101] Second, when the time-frequency resource position of the PUSCH of one of the UEs cannot be used to transmit the PUSCH due to a conflict with the PRACH, how to ensure that the time-frequency resources occupied by the PUSCHs sent by the two UEs are exactly the same.

[0102] Third, when the time-frequency resource positions of the PUSCHs of two UEs need to multiplex uplink control information (UCI) due to a conflict with the PUCCH, how to ensure that the content carried by the transport blocks (TBs) of the PUSCHs sent by the two UEs is exactly the same.

[0103] Based on this, in the embodiments of the present application, the network device configures a first set for multiple terminals jointly; or configures a second set for each of the multiple terminals separately; wherein, both the first set and the second set are used to indicate the time-frequency resource positions that cannot be used to map the PUSCH when the multiple terminals perform PUSCH transmission; both the first set and the second set are composed of X time-frequency resources; X is an integer greater than or equal to 1.

[0104] See Figure 1 , Figure 1 is a schematic flowchart of the implementation process of the configuration method in the embodiments of the present application, which is applied to a network device, as Figure 1 shown, the method includes step 101:

[0105] Step 101: Configure a first set for multiple terminals jointly; or configure a second set for each of the multiple terminals separately; wherein, both the first set and the second set are used to indicate the time-frequency resource positions that cannot be used to map the PUSCH when the multiple terminals perform PUSCH transmission; both the first set and the second set are composed of X time-frequency resources; X is an integer greater than or equal to 1.

[0106] As an example, the first set can be configured for multiple terminals jointly through the same DCI or the same MAC CE. In this way, the multiple terminals can all receive the first set.

[0107] For example, the network device can send the same DCI to the multiple terminals respectively to configure the first set for the multiple terminals jointly. The DCI is a DCI scrambled with the same group radio network temporary identifier (G-RNTI). Therefore, the multiple terminals can all demodulate the DCI and thus can all receive the first set.

[0108] Alternatively, the network device may separately send the same MAC CE to the multiple terminals to commonly configure the first set for the multiple terminals. The MAC CE is sent by a PDSCH using the same scrambling code. Therefore, the multiple terminals can all demodulate the DCI and thus can all receive the first set.

[0109] As an example, the second set may be separately configured for the multiple terminals by different DCIs or different MAC CEs. In this way, each terminal receives its own second set.

[0110] For example, the network device may separately send different DCIs to the multiple terminals to separately configure the second set for the multiple terminals. Each DCI is a DCI scrambled with a different RNTI. Therefore, each terminal separately demodulates its own DCI and thus receives its own second set.

[0111] Alternatively, the network device may separately send different MAC CEs to the multiple terminals to separately configure the second set for the multiple terminals. Each MAC CE is sent by a PDSCH using a different scrambling code. Therefore, each terminal separately demodulates its own DCI and thus receives its own second set.

[0112] As an example, taking terminal UE1 and terminal UE2 as an example, the network device may use the same DCI to jointly configure one first set for terminal UE1 and terminal UE2. The first set is represented as {first time-frequency resource, second time-frequency resource..., Xth time-frequency resource}. The DCI is a DCI scrambled with the same G-RNTI. In this way, both terminal UE1 and terminal UE2 can demodulate the DCI and thus can both receive the first set. The first set is used to indicate the time-frequency resource positions that cannot be used for mapping PUSCH during PUSCH transmission of terminal UE1 and terminal UE2.

[0113] As an example, taking terminal UE1 and terminal UE2 as an example, the network device uses different DCIs to separately configure their own second sets for terminal UE1 and terminal UE2. Suppose the second set corresponding to terminal UE1 is represented as {first time-frequency resource, second time-frequency resource..., Xth time-frequency resource}, and the second set corresponding to terminal UE2 is represented as {first time-frequency resource, second time-frequency resource..., Xth time-frequency resource}. Each DCI is a DCI scrambled with a different RNTI. In this way, terminal UE1 demodulates its own DCI and thus receives its own second set, and terminal UE2 demodulates its own DCI and thus receives its own second set. The second set is used to indicate the time-frequency resource positions that cannot be used for mapping PUSCH during PUSCH transmission of terminal UE2.

[0114] As an example, the multiple terminals may perform joint transmission of PUSCH in a single frequency network (SFN), space division multiplexing (SDM), or coherent joint transmission (CJT) manner.

[0115] In some embodiments, the configuration of the time-frequency resources includes:

[0116] First information; the first information characterizes the frequency domain resources that cannot be used to map the PUSCH;

[0117] And / or,

[0118] Second information; the second information characterizes the time domain resources that cannot be used to map the PUSCH;

[0119] And / or,

[0120] The identifier of the SRS resource, or the identifier of the SRS resource set, or the identifier of the PRACH;

[0121] And / or,

[0122] First parameter; the first parameter establishes an association relationship with the SRS, and / or the first parameter establishes an association relationship with the PRACH resource;

[0123] And / or,

[0124] The period and offset corresponding to the first information, or the period and offset corresponding to the second information;

[0125] And / or,

[0126] The time-frequency resources for the multiple terminals to transmit SRS and PRACH.

[0127] As an example, the first information may also be described as frequency domain information. This frequency domain information can be used to indicate that a part of the frequency domain resources cannot be used to map the PUSCH.

[0128] For example, for frequency domain resources at the resource block (RB) or resource block group (RBG) level, the positions of RBs or RBGs that cannot be used for PUSCH transmission are indicated by a bitmap, where 1 corresponds to the position of an RB or RBG that cannot be used for PUSCH transmission, and 0 corresponds to the position of an RB or RBG that can be used for PUSCH transmission, or 1 corresponds to the position of an RB or RBG that can be used for PUSCH transmission, and 0 corresponds to the position of an RB or RBG that cannot be used for PUSCH transmission.

[0129] As an example, the second information can also be described as time domain information. This time domain information can be used to indicate that a part of the time domain resources cannot be used for mapping PUSCH.

[0130] For example, for symbols or symbol groups, the positions of symbols or symbol groups that cannot be used for PUSCH transmission are indicated by a bitmap, where 1 corresponds to the position of a symbol or symbol group that cannot be used for PUSCH transmission, and 0 corresponds to the position of a symbol or symbol group that can be used for PUSCH transmission, or 1 corresponds to the position of a symbol or symbol group that can be used for PUSCH transmission, and 0 corresponds to the position of a symbol or symbol group that cannot be used for PUSCH transmission.

[0131] As an example, taking UE1 and UE2 as an example, the identifiers of the aperiodic (AP) SRS resources of UE1 and UE2, or the identifier of an SRS resource set, or the identifier of a PRACH are configured into the time-frequency resource list to indicate that the time-frequency resource positions of the resources or channels cannot be used for mapping PUSCH.

[0132] As an example, the first parameter can be the C-RNTI of the terminal or a high-layer parameter configured by the network. The first parameter establishes an association relationship with the SRS and is used for the terminal to determine the time-frequency resource position of the SRS resource. The first parameter establishes an association relationship with the PRACH resource and is used for the terminal to determine the time-frequency resource position of the PRACH.

[0133] As an example, the period and offset corresponding to the first information are used for the terminal to determine the time slot and symbol positions corresponding to the time-frequency resource positions that cannot be used for mapping PUSCH. The period and offset corresponding to the second information are used for the terminal to determine the time slot and symbol positions corresponding to the time-frequency resource positions that cannot be used for mapping PUSCH.

[0134] As an example, taking UE1 and UE2 as an example, the configuration of the time-frequency resources includes the time-frequency resources where UE1 and UE2 may transmit channels or signals such as SRS and PRACH, and the positions of these time-frequency resources cannot be used for mapping PUSCH.

[0135] In some embodiments, the method further includes:

[0136] When the multiple terminals perform PUSCH transmission, a subset of the first set is indicated by DCI;

[0137] Or,

[0138] When the multiple terminals perform PUSCH transmission, a subset of the first set is indicated by MAC CE;

[0139] Or,

[0140] When the multiple terminals perform PUSCH transmission, a first bit is added to the DCI;

[0141] Wherein,

[0142] The subset is used to indicate the time-frequency resource positions that cannot be used for mapping the PUSCH;

[0143] The first bit is used to indicate the time-frequency resource positions that cannot be used for mapping the PUSCH.

[0144] As an example, all elements in the subset are elements in the first set. All elements in this subset may be equal to all elements in the first set, or all elements in this subset are not equal to all elements in the first set. Wherein, in the case where all elements in this subset are not equal to all elements in the first set, this subset can also be called a proper subset.

[0145] First case, for the manner of indicating a subset of the first set by DCI or MAC CE. Specifically, by log2(X) bit, one time-frequency resource is selected from the time-frequency resource set to indicate the time-frequency resource positions that cannot be used for mapping the PUSCH during PUSCH transmission; or, in the form of a bitmap of X bit, at most X time-frequency resources are selected from the time-frequency resource set to indicate the time-frequency resource positions that cannot be used for mapping the PUSCH during PUSCH transmission.

[0146] Second case, when a subset of the first set is not indicated by DCI or MAC CE, the first set commonly configured by the network device for the multiple terminals is directly used to indicate the time-frequency resource positions that cannot be used for mapping the PUSCH during PUSCH transmission by the multiple terminals.

[0147] For the third case, a method of adding a first bit in DCI is considered. Assume that the first bit is 1 bit. Herein, 1 indicates that the first set commonly configured by the network device for the multiple terminals is directly used to indicate the time-frequency resource positions that cannot be used for mapping PUSCH when the multiple terminals perform PUSCH transmission; 0 indicates that there are no time-frequency resource positions that cannot be used for mapping PUSCH when the multiple terminals perform PUSCH transmission.

[0148] It should be noted that the first set commonly configured by the network device for the multiple terminals, which is used to indicate the time-frequency resource positions that cannot be used for mapping PUSCH when the multiple terminals perform PUSCH transmission, has the following advantages: Taking two UEs as an example, when the time-frequency resource position for one of the two UEs (UE1) to transmit PUSCH cannot be used for PUSCH transmission due to a conflict with the SRS or PRACH other than PUSCH sent by the other UE (UE2), the first set is used to indicate the time-frequency resource positions that cannot be used for mapping PUSCH when UE1 performs PUSCH transmission, so as to free up the time-frequency resource positions that cannot be used for mapping PUSCH, and prevent conflicts with the SRS or PRACH other than PUSCH sent by UE2. In this way, UE1 will not map PUSCH to this time-frequency resource position, but only transmit PUSCH at the time-frequency resource positions where PUSCH can be mapped, thereby achieving conflict resolution. Similarly, if the PUSCH sent by UE2 conflicts with the transmission of other channels or signals other than PUSCH sent by UE1, the first set or the second set is used to indicate the time-frequency resource positions that cannot be used for mapping PUSCH when UE2 performs PUSCH transmission, so as to free up the time-frequency resource positions that cannot be used for mapping PUSCH, and prevent conflicts with other channels or signals other than PUSCH sent by UE1. In this way, UE2 will not map PUSCH to this time-frequency resource position, but only transmit PUSCH at the time-frequency resource positions where PUSCH can be mapped, thereby achieving conflict resolution.

[0149] It should be noted that for each terminal, the time-frequency resources scheduled by the network device are the same, and the time-frequency resources that cannot be used for mapping PUSCH are also the same. Thus, by removing the time-frequency resources that cannot be used for mapping PUSCH from the scheduled time-frequency resources, the time-frequency resources available for sending PUSCH are the same, which can ensure that the time-frequency resources occupied by the PUSCHs sent by two UEs are exactly the same. Determining the time-frequency resource positions for PUSCH transmission according to whether real-time scheduling conflicts occur can maximize resource utilization.

[0150] In some embodiments, the method further includes:

[0151] When the multiple terminals perform PUSCH transmission, the time-frequency resource positions in the second set that cannot be used for mapping PUSCH are indicated by DCI or MAC CE.

[0152] In some embodiments, the method further includes:

[0153] When the multiple terminals perform PUSCH transmission, the association relationships between the second set and the first parameter are respectively configured for the multiple terminals, where the first parameter is the C-RNTI of the terminal or a high-layer parameter configured by the network;

[0154] The time-frequency resource positions that cannot be used for mapping PUSCH for each terminal are indicated by multiple fields in DCI; wherein, the multiple fields correspond to the second set configured for each terminal.

[0155] As an example, for M-DCI scheduling, the terminal determines the time-frequency resource positions that cannot be used for mapping PUSCH according to the time-frequency resource positions indicated by DCI.

[0156] As an example, taking terminal UE1 and terminal UE2 as an example, the network device configures the second set for terminal UE1 and terminal UE2 respectively. The second set corresponding to terminal UE1 is represented by time-frequency resource set 1, and the second set corresponding to terminal UE2 is represented by time-frequency resource set 2. For S-DCI scheduling, the time-frequency resource set 1 configured by the network device is associated with the C-RNTI of UE1, and the time-frequency resource set 2 is associated with the C-RNTI of UE2.

[0157] As an example, taking terminal UE1 and terminal UE2 as an example, the network device configures the second set for terminal UE1 and terminal UE2 respectively. The second set corresponding to terminal UE1 is represented by time-frequency resource set 1, and the second set corresponding to terminal UE2 is represented by time-frequency resource set 2. Two fields in DCI are required to respectively indicate the time-frequency resource positions that cannot be used for mapping PUSCH for terminal UE1 and terminal UE2. Among them, the first field corresponds to time-frequency resource set 1, that is, corresponding to terminal UE1; the second field corresponds to time-frequency resource set 2, that is, corresponding to terminal UE2; vice versa.

[0158] In some embodiments, a first rule is configured for the multiple terminals jointly;

[0159] Or,

[0160] The first rule is configured for each of the multiple terminals respectively;

[0161] Among them, the first rule is used to indicate that in the case of multiplexing PUSCH transmission and UCI, the UCI of each terminal is concatenated in a preset order to obtain the concatenated UCI, and the concatenated UCI is multiplexed with the PUSCH transmission. If the number of bits of the concatenated UCI is greater than a first value, then M bits are respectively deleted from the UCI of each terminal, where M is equal to the ratio of the first value to the second value, and the second value represents the number of terminals jointly performing PUSCH transmission.

[0162] As an example, the first rule can be jointly configured for multiple terminals through the same DCI or the same MAC CE. In this way, the multiple terminals can all receive the first rule.

[0163] For example, the network device can separately send the same DCI to the multiple terminals to jointly configure the first rule for the multiple terminals. The DCI is a DCI scrambled with the same G-RNTI. Therefore, the multiple terminals can all demodulate the DCI and thus can all receive the first rule.

[0164] Or, the network device can separately send the same MAC CE to the multiple terminals to jointly configure the first rule for the multiple terminals. The MAC CE is sent by a PDSCH using the same scrambling code. Therefore, the multiple terminals can all demodulate the DCI and thus can all receive the first rule.

[0165] As an example, the first rule can be separately configured for the multiple terminals through different DCIs or different MAC CEs. In this way, each terminal receives its own first rule.

[0166] For example, the network device can separately send different DCIs to the multiple terminals to separately configure the first rule for the multiple terminals. Each DCI is a DCI scrambled with a different RNTI. Therefore, each terminal demodulates its own DCI respectively and thus receives its own first rule.

[0167] Or, the network device can separately send different MAC CEs to the multiple terminals to separately configure the first rule for the multiple terminals. Each MAC CE is sent by a PDSCH using a different scrambling code. Therefore, each terminal demodulates its own DCI respectively and thus receives its own first rule.

[0168] As an example, taking the terminal UE1 and the terminal UE2 as examples, when there is multiplexing of PUSCH and UCI in the terminal UE1 and / or the terminal UE2, the UCI of the terminal UE1 and the terminal UE2 are concatenated in sequence according to a predetermined order, and multiplexed onto the PUSCH together. The terminal UE1 and the terminal UE2 send the PUSCH carrying the concatenated UCI of the terminal UE1 and the terminal UE2. When the number of bits of the concatenated UCI exceeds X bits, for the UCI of each UE, M bits are discarded, where M = X / N bits, and N is the number of UEs jointly performing PUSCH transmission. It should be noted that since the transport block (TB) of the PUSCH transmission sent by the terminal UE1 carries the concatenated UCI, and the TB of the PUSCH transmission sent by the terminal UE2 carries the concatenated UCI, the content carried by the TBs of the PUSCH transmissions sent by UE1 and UE2 is the concatenated UCI, and the processing methods of the concatenated UCI by the terminal UE1 and the terminal UE2 are the same. In this way, it can be ensured that the content carried by the TBs of the PUSCH transmissions sent by the terminal UE1 and the terminal UE2, that is, the concatenated UCI, is exactly the same.

[0169] It should be noted that for the scenario of PUSCH joint transmission for multiple UEs, taking UE1 and UE2 as examples, when the time-frequency resource position of the PUSCH sent by one of the UEs (UE1) cannot be transmitted due to a conflict with an SRS or PRACH other than the PUSCH sent by UE2, based on the first set or the second set configured in the embodiments of the present application (the information is carried in DCI or MAC CE), it can be indicated that the time-frequency resource position that cannot be used for PUSCH transmission when UE1 performs PUSCH transmission is freed up to prevent conflicts with other channels or signals other than the PUSCH sent by UE2. In this way, UE1 will not map the PUSCH to this time-frequency resource position, but only transmit the PUSCH at the time-frequency resource positions where the PUSCH can be mapped, thereby achieving conflict resolution. Similarly, if there is a conflict between the PUSCH sent by UE2 and the transmission of other channels or signals other than the PUSCH sent by UE1, the first set or the second set is used to indicate the time-frequency resource position that cannot be used for mapping the PUSCH when UE2 performs PUSCH transmission, so as to free up the time-frequency resource position that cannot be used for mapping the PUSCH to prevent conflicts with other channels or signals other than the PUSCH sent by UE1. In this way, UE2 will not map the PUSCH to this time-frequency resource position, but only transmit the PUSCH at the time-frequency resource positions where the PUSCH can be mapped, thereby achieving conflict resolution.

[0170] In addition, for each terminal, the time-frequency resources scheduled by the network device are the same, and the time-frequency resources that cannot be used to map the PUSCH are also the same. In this way, by removing the time-frequency resources that cannot be used to map the PUSCH from the scheduled time-frequency resources, the time-frequency resources available for transmitting the PUSCH are the same, thereby ensuring that the time-frequency resources occupied by the PUSCHs transmitted by two UEs are exactly the same. This dynamic information indication can determine the time-frequency resource position for PUSCH transmission according to the real-time scheduling situation, maximizing resource utilization.

[0171] The embodiments of this application have the following advantages:

[0172] (1) In the scenario of joint PUSCH transmission for multiple UEs, taking two UEs as an example, if there is a conflict between the PUSCH transmitted by UE1 and the transmission of other channels or signals other than the PUSCH transmitted by UE2, the time-frequency resource positions that cannot be used to map the PUSCH during PUSCH transmission by UE1 are indicated through the first set or the second set, so as to free up the time-frequency resource positions that cannot be used to map the PUSCH, preventing conflicts with other channels or signals other than the PUSCH transmitted by UE2. In this way, UE1 will not map the PUSCH to this time-frequency resource position, but only transmit the PUSCH at the time-frequency resource positions where the PUSCH can be mapped, thus achieving conflict resolution. Similarly, if there is a conflict between the PUSCH transmitted by UE2 and the transmission of other channels or signals other than the PUSCH transmitted by UE1, the time-frequency resource positions that cannot be used to map the PUSCH during PUSCH transmission by UE2 are indicated through the first set or the second set, so as to free up the time-frequency resource positions that cannot be used to map the PUSCH, preventing conflicts with other channels or signals other than the PUSCH transmitted by UE1. In this way, UE2 will not map the PUSCH to this time-frequency resource position, but only transmit the PUSCH at the time-frequency resource positions where the PUSCH can be mapped, thus achieving conflict resolution.

[0173] (2) For each terminal, the time-frequency resources scheduled by the network device are the same, and the time-frequency resources that cannot be used to map the PUSCH are also the same. In this way, by removing the time-frequency resources that cannot be used to map the PUSCH from the scheduled time-frequency resources, the time-frequency resources available for transmitting the PUSCH are the same, thereby ensuring that the multiple terminals can transmit the PUSCH at the same time-frequency resources.

[0174] (3) Multiple terminals jointly perform PUSCH transmission. When PUSCH and UCI are multiplexed, the content carried in the TB of the PUSCH transmission sent by each terminal is the concatenated UCI, and each terminal processes the concatenated UCI in the same way, so as to ensure that the content carried in the TB of the PUSCH transmissions sent by the multiple terminals is exactly the same.

[0188] And / or,

[0189] The time-frequency resources for the multiple terminals to transmit SRS and PRACH.

[0190] In some embodiments, when the plurality of terminals perform PUSCH transmission, a subset of the first set is indicated by DCI; or, when the plurality of terminals perform PUSCH transmission, a subset of the first set is indicated by MAC CE; or, when the plurality of terminals perform PUSCH transmission, a first bit is added to the DCI; wherein, the subset is used to indicate the time-frequency resource positions that cannot be used for mapping the PUSCH; the first bit is used to indicate the time-frequency resource positions that cannot be used for mapping the PUSCH.

[0191] In some embodiments, when the plurality of terminals perform PUSCH transmission, the time-frequency resource positions in the second set that cannot be used for mapping PUSCH are indicated by DCI or MAC CE.

[0192] In some embodiments, the method further includes:

[0193] When the plurality of terminals perform PUSCH transmission, receiving the association relationship between the second set and a first parameter, where the first parameter is the C-RNTI of the terminal or a high-layer parameter configured by the network; indicating the time-frequency resource positions that cannot be used for mapping PUSCH for each terminal through a plurality of fields in the DCI; wherein, the plurality of fields correspond to the second sets configured for each terminal.

[0194] In some embodiments, the method further includes:

[0195] Receiving a first rule configured by the network device for the plurality of terminals jointly; or receiving the first rule configured by the network device for each of the plurality of terminals separately; wherein, the first rule is used to indicate that in the case of multiplexing PUSCH transmission and UCI, the UCI of each terminal is concatenated in a preset order to obtain the concatenated UCI, and the concatenated UCI is multiplexed with the PUSCH transmission. If the number of bits of the concatenated UCI is greater than a first value, M bits are respectively deleted from the UCI of each terminal, where M is equal to the ratio of the first value to a second value, and the second value represents the number of terminals jointly performing PUSCH transmission.

[0196] Embodiments of the present application have the following advantages:

[0197] (1) In the scenario of joint PUSCH transmission for multiple UEs, taking 2 UEs as an example, if there is a conflict between the PUSCH transmitted by UE1 and the transmission of other channels or signals other than PUSCH transmitted by UE2, the time-frequency resource positions that cannot be used for mapping the PUSCH when UE1 performs PUSCH transmission are indicated through the first set or the second set, so as to free up the time-frequency resource positions that cannot be used for mapping the PUSCH, to prevent conflicts with other channels or signals other than PUSCH transmitted by UE2. In this way, UE1 will not map the PUSCH to this time-frequency resource position, but only transmit the PUSCH at the time-frequency resource positions where the PUSCH can be mapped, thereby achieving conflict resolution. Similarly, if there is a conflict between the PUSCH transmitted by UE2 and the transmission of other channels or signals other than PUSCH transmitted by UE1, the time-frequency resource positions that cannot be used for mapping the PUSCH when UE2 performs PUSCH transmission are indicated through the first set or the second set, so as to free up the time-frequency resource positions that cannot be used for mapping the PUSCH, to prevent conflicts with other channels or signals other than PUSCH transmitted by UE1. In this way, UE2 will not map the PUSCH to this time-frequency resource position, but only transmit the PUSCH at the time-frequency resource positions where the PUSCH can be mapped, thereby achieving conflict resolution.

[0198] (2) For each terminal, the time-frequency resources scheduled by the network device are the same, and the time-frequency resources that cannot be used for mapping the PUSCH are also the same. Thus, by removing the time-frequency resources that cannot be used for mapping the PUSCH from the scheduled time-frequency resources, the time-frequency resources available for sending PUSCH are the same, so as to ensure that the multiple terminals can send PUSCH at the same time-frequency resources.

[0199] (3) When multiple terminals jointly perform PUSCH transmission and PUSCH is multiplexed with UCI, the content carried by the TB of the PUSCH transmission sent by each terminal is the concatenated UCI, and each terminal processes the concatenated UCI in the same way, so as to ensure that the content carried by the TB of the PUSCH transmission sent by the multiple terminals is exactly the same.
