However, in the case of multiple transmission and reception nodes, especially in the Ultra-Reliable Low-Latency Communication scenario, there are usually multiple spatial relationships, corresponding to different beams and repeated transmissions, etc., which makes the communication environment and resource configuration complex. Currently, there is a lack of an effective mechanism for the terminal to decide how to use the uplink transmission resources to send uplink transmissions for multiple TRPs and multiple beams.

[0043] The present application will be described below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. Additionally, it should be noted that for the sake of description, only the parts related to the present application rather than all the structures are shown in the accompanying drawings.

[0044] Based on the joint transmission technology of Multi-TRP, the transmission throughput in a wireless communication system is effectively improved. In the New Radio (NR) technology, there is also a Multi-Panel transmission. The terminal can use multiple antenna panels for transmission to obtain higher spectral efficiency. In addition, the repeated transmission or reception using Multi-TRP or Multi-Panel can increase the probability for the receiving end to obtain correct information, and effectively improve the transmission reliability in the Ultra-reliable and Low Latency Communications (URLLC) scenario. However, due to the imperfect indication for the uplink transmission, especially when the terminal supports Multi-Panel, it is difficult for the terminal to decide how to utilize the uplink transmission resources for uplink transmission. Therefore, it is also difficult to perform power control, resource allocation, etc. for each Multi-Panel separately, and the uplink transmissions of multiple TRPs interfere with each other, greatly reducing the transmission performance and resulting in low reliability of the uplink transmission.

[0045] In an embodiment of the present application, an indication method is provided, which is applied to a serving node. The serving node sends indication information to indicate the resource configuration for sending uplink transmission to the terminal, so as to provide a basis for the terminal to use the corresponding resources to send UCI and ensure the reliability of the uplink transmission.

[0046] Figure 1 Flowchart of an indication method provided for an embodiment, as Figure 1 shown, the method provided in this embodiment includes step 110 and step 120.

[0047] In step 110, indication information is sent, and the indication information is used to indicate the resource configuration for uplink transmission.

[0048] In step 120, the uplink control information UCI sent by the terminal is received.

[0049] In this embodiment, the serving node is, for example, a base station, and the terminal is, for example, a user equipment (UE). Resource configuration may include a set of resources available to the terminal, resources for sending uplink transmissions, the spatial relationships included in the resources, the number of repetitions of the uplink control channel, and the transmission mode of the uplink transmission, etc., for indicating the resources used by the terminal to send uplink transmissions and the specific transmission mode. UCI is a signaling for uplink transmissions sent by the terminal to the serving node, including channel state information (CSI), hybrid automatic repeat request (HARQ), scheduling request, etc., and is mainly transmitted through the physical uplink control channel (PUCCH). In this embodiment, the terminal may send UCI to multiple TRPs (such as multiple base stations), and the serving node indicates multiple resource configurations to the terminal, respectively corresponding to the paths between the terminal and multiple TRPs.

[0050] In one embodiment, it further includes:

[0051] Step 101: Configure at least one physical uplink control channel resource set (PUCCH Resource Set) for the terminal through high-layer signaling, where each physical uplink control channel resource set contains at least one physical uplink control channel resource (PUCCH Resource); activate at least one spatial relation for each PUCCH Resource of the terminal through the media access control layer control element (MAC-CE).

[0052] In this embodiment, for the serving node, multiple PUCCH resource sets are configured for the UE through the high layer, each PUCCH resource set contains multiple PUCCH resources, one or more spatial relations are activated for each PUCCH resource through the MAC-CE, and the terminal uses one or more spatial relations in the PUCCH resources indicated by the base station to send UCI to the TRP.

[0053] In one embodiment, the indication information includes downlink control information (DCI); the physical uplink control channel resource indicator field (PRI) in the DCI is used to indicate the target resource, and the target resource is the uplink transmission resource used by the terminal to send UCI, and the target resource contains at least one spatial relation.

[0054] In this embodiment, the serving node indicates the PUCCH resource used by the UE to send UCI, that is, the target resource, to the UE through the uplink control channel resource indication field in the DCI, thereby providing a basis for the terminal to send uplink transmissions.

[0055] In one embodiment, the indication information includes DCI; the extended TPC command field (Transmission Power Control Command Field, TPC Command Field) in the DCI is used to adjust the uplink transmission power of the terminal to send UCI; the extended TPC command field is used to extend the range of the original TPC indication value or the number of extended TPC command fields; the function of the extended TPC command field is determined according to the number of spatial relationships included in the target resource and the number of uplink control channel retransmissions.

[0056] In this embodiment, the terminal can use one or more spatial relationships included in the target resource to send UCI, and use one or more beams to transmit to the same or different TRPs. By extending the original TPC command field in the DCI, transmission power control for different beams can be achieved or the indication value range for the same beam can be increased. Here, the function of the extended TPC command field refers to extending the range of the original TPC indication value or extending the number of TPC command fields.

[0057] Figure 2 FIG. is a schematic diagram of transmission power control for different beams provided in an embodiment. As Figure 2 shown, the base station configures two transmission beams for the UE, namely beam 1 and beam 2, corresponding to path 1 and path 2 respectively. Among them, path 2 is blocked and has a greater path loss. Based on this, the base station determines that the transmission power of the UE is too low; while the transmission condition of path 1 is better, and the base station determines that the transmission power of the UE is too high. The original TPC command field in the DCI can only indicate one TPC indication value for rapid power adjustment. If the base station indicates a TPC according to beam 1 to notify the UE to reduce the transmission power by 1 dB, then when sending beam 2, it also needs to be reduced by 1 dB accordingly, resulting in deterioration of the transmission performance after the transmission power of path 2 is reduced; and if the base station indicates a TPC indication value according to beam 2 to notify the UE to increase the transmission power by 1 dB, when sending beam 1, it also needs to be increased by 1 dB accordingly, resulting in too high a transmission power corresponding to beam 1, even interfering with the transmission of the same time-frequency resource, and consuming too much energy, which is not conducive to energy saving.

[0058] Table 1 shows the mapping relationship between the original TPC command field and the power control indication value. As shown in Table 1, for DCI format 1_0, DCI format 1_1, or DCI format 2_2, the TPC command field can indicate the following four power control indication values (offset values).

[0059] Table 1 Mapping Relationship between Original TPC Command Field and Power Control Indication Value

[0060] Original TPC command field Power control indication value [dB] 0 -1 1 0 2 1 3 3

[0061] In this embodiment, the serving node configures an uplink control channel resource set for the UE through high-layer signaling, activates one or more spatial relationships for each uplink control channel resource in the uplink control channel resource set through MAC-CE, and then indicates the target resource through the uplink control channel resource indication field in DCI. By expanding the original TPC command field in DCI, an extended TPC command field is obtained, thereby expanding the range of the original TPC indication value or the number of TPC command fields, and adjusting the uplink transmission power of the terminal with a larger indication value range or more indication field quantities. During the PUCCH retransmission process, the TPC command can correspond to one or more beams of multiple transmissions, thereby improving the flexibility of uplink transmission indication.

[0062] For example, increase the number of TPC command fields. Taking the case where the UE uses two spatial relationships to correspond to beams for transmission as an example, the TPC field in DCI is increased to 2, and the number of occupied bits is increased from 2 bits to 4 bits.

[0063] Table 2 shows the mapping relationship between the extended TPC command field and the power control indication values of different beams. As shown in Table 2, the extended TPC command field occupies 4 bits. The first 2 bits are used to indicate the TPC indication value of the first beam of the UE, and the last 2 bits are used to indicate the TPC indication value corresponding to the second beam of the UE. If the indication value of the extended TPC command field is 0010, it means that the transmission power will be reduced by 1 dB for beam 1 and increased by 1 dB for beam 2.

[0064] Table 2 Mapping Relationship between Extended TPC Command Field and Power Control Indication Values of Different Beams

[0065]

[0066] Another example is that the TPC command field expands the original TPC indication value range. Taking the case where the UE uses one spatial relationship to correspond to a beam for transmission as an example, the TPC field in DCI still remains 1, the number of occupied bits is increased from 2 bits to 4 bits, and all 4 bits in the extended TPC command field are used to indicate a TPC indication value.

[0067] Table 3 shows the mapping relationship between the extended TPC command field and the extended power control indication value (the mapping relationship is not limited to this). As shown in Table 3, the extended TPC command field occupies 4 bits, and all 4 bits are used to indicate a TPC indication value. The range of the TPC indication value is expanded from the original [-1, 3] to [-8, 7]. The first to fourth rows in Table 3 are the same as those in Table 1, maintaining the original TPC indication value unchanged; the fifth to sixteenth rows expand the TPC indication value, expanding and refining the indication range. When the power to be adjusted is relatively large, for example, when the base station needs to notify the UE to reduce the power by 3 dB, according to the original TPC command field, multiple adjustments are required to meet the power requirement. However, according to the extended TPC command field shown in Table 3, the DCI can directly meet the requirement through one TPC adjustment, thereby improving the flexibility and adjustment efficiency of power control.

[0068] Table 3 Mapping Relationship between Extended TPC Command Field and Extended Power Control Indication Value

[0069]

[0070] In this embodiment, the terminal can select an uplink control channel resource set from the configured resource sets according to the number of UCI bits to be transmitted, and then determine the target resource for transmitting UCI according to the uplink control channel resource indication field in the DCI, use the target resource for the uplink transmission of UCI, and adjust the power of the transmission beam accordingly according to the extended TPC command field in the DCI.

[0071] In one embodiment, it further includes:

[0072] Step 102: Semi-statically indicate the number of bits of the extended TPC command field in the DCI through a first high-layer parameter.

[0073] In this embodiment, the first high-layer parameter (DCI-PayloadSize) semi-statically configures and notifies the UE of the payload size of the DCI to be received, so as to indicate the number of bits of the TPC command field in the DCI, so that the UE can extract the corresponding transmission power control indication information from the received DCI. After the UE determines the number of bits of the TPC command field, it is still unable to determine whether these bits belong to one or multiple fields, so it is unable to determine whether these bits are used to indicate the TPC of one or multiple beams, and it is also necessary to jointly determine according to the number of spatial relationships included in the target resource indicated by the serving node and the indicated number of repeated transmissions.

[0074] In one embodiment, it further includes:

[0075] Step 103: Configure the number of repeated transmissions N of the uplink control channel through a second high-layer parameter.

[0076] Repetition transmission can improve the reliability of data (or signaling) transmission. The M repetitively transmitted data (or signaling) carry exactly the same information, and the M repetitively transmitted data (or signaling) can come from M different TRPs or the same TRP. In this embodiment, the repetition transmission count N is configured by the second higher-layer parameter (nrofslots) for the UE to determine the transmission count of the TPC command field in the PUCCH.

[0077] In one embodiment, when the target resource includes at least two spatial relationships and the repetition transmission count is equal to 1, the extended TPC command field in the DCI is used to extend the original TPC indication value range and to adjust the uplink transmission power corresponding to the spatial relationship used for the uplink transmission; when the target resource corresponds to at least two spatial relationships and the repetition transmission count is greater than 1, the extended TPC command field is used to extend the number of TPC fields and to adjust the uplink transmission power corresponding to the spatial relationships used for multiple uplink transmissions; when the target resource corresponds to one spatial relationship, regardless of whether the repetition count is greater than 1, the extended TPC command field in the DCI is used to extend the original TPC indication value range and to adjust the uplink transmission power corresponding to this spatial relationship.

[0078] In this embodiment, for the case where the target resource includes multiple spatial relationships, the UE supports transmitting the UCI using multiple beams. In this case, it is also necessary to determine whether the extended TPC command field is used to extend the original TPC indication value range or to extend the number of TPC command fields according to the repetition transmission count N configured by the second higher-layer parameter. Specifically, it includes:

[0079] 1) If the repetition transmission count N is 1, the UE only needs to transmit the uplink transmission once in one time slot. The UE can select the first beam among the multiple spatial relationships corresponding to the target resource to transmit this uplink transmission. In this case, the extended TPC command field in the DCI is used to extend the original TPC indication value range, such as Table 3, and to adjust the uplink transmission power corresponding to one of the spatial relationships (such as the first beam).

[0080] 2) If the repetition transmission count N is greater than 1, the UE needs to repetitively transmit the uplink transmission in N time slots. In this case, the extended TPC command field is used to extend the number of TPC fields. For example, when the target resource includes two spatial relationships, the DCI includes two TPC fields, and the first 2 bits are used to indicate the TPC indication value of beam 1, and the last 2 bits are used to indicate the TPC indication value corresponding to beam 2.

[0081] In addition, when the target resource indicated by the DCI contains a spatial relationship, regardless of whether the number of retransmissions N is greater than 1, the UE only supports transmitting the UCI using one beam. In this case, the TPC command field in the DCI is used to extend the original TPC indication value range, such as Table 3, and is used to adjust the uplink transmission power of this spatial relationship.

[0082] In one embodiment, the target resource includes the starting symbol position, duration, and physical resource block index of the uplink control channel transmission; the method further includes at least one of the following:

[0083] For PUCCH format 0, when the target resource indicated by the DCI corresponds to at least two spatial relationships, the initial cyclic shift is configured for different spatial relationships of this target resource through a third higher-layer parameter.

[0084] For PUCCH format 1, when the target resource indicated by the DCI corresponds to at least two spatial relationships, the initial cyclic shift and orthogonal spreading code are configured for different spatial relationships of this target resource through a third higher-layer parameter.

[0085] For PUCCH formats 2, 3, or 4, when the target resource indicated by the DCI corresponds to at least two spatial relationships, the scrambling sequence parameters are configured for different spatial relationships of this target resource through a third higher-layer parameter.

[0086] In this embodiment, the UE can use multiple beams to send uplink transmissions to multiple TRPs. Taking two TRPs (TRP0 and TRP1 respectively) as an example, the cells corresponding to these two TRPs may be different, and the corresponding users may also be different. If the same cyclic shift and scrambling sequence in the same target resource are used for different beams, it will cause interference with users under another TRP and reduce the transmission performance. In this embodiment, during the process of the serving node indicating the target resource to the UE, in addition to indicating the starting symbol position, duration, and physical resource block index of the target resource, additional parameters are also indicated for different PUCCH formats to distinguish the transmission paths and beams of different TRPs, avoid interference between different paths, and improve the reliability of multi-TRP transmission.

[0087] 1) For PUCCH format 0, on a given physical time-frequency resource, multi-user multiplexing can be performed through different cyclic shifts of the transmission sequence. In the process of the high-layer RRC signaling configuring the PUCCH resource for the UE, in addition to notifying the starting symbol position, duration, and physical resource block index of the PUCCH, the index of the initial cyclic shift (AdditionalinitialCyclicShift) also needs to be notified additionally, and the value range is 0 to 11.

[0088] Figure 3Schematic diagram of uplink transmission and initial cyclic shift index provided for an embodiment, as Figure 3 shown, when the UE uses PUCCH format 0 for transmission and the target resources indicated by DCI contain two spatial relationships, the UE is indicated two different initialCyclicShift values associated with different TRPs. For example, the value indicated by the original parameter (initialCyclicShift) corresponds to the beam sent to TRP0; the value indicated by the additional parameter (AdditionalinitialCyclicShift) corresponds to the beam sent to TRP1.

[0089] 2) For PUCCH format 1, on a given physical time-frequency resource, multi-user multiplexing can be performed through different cyclic shifts of the transmission sequence and time-domain orthogonal spreading codes. In the process of configuring PUCCH resources for the UE, in addition to notifying the starting symbol position, duration, and physical resource block index of the PUCCH, the high-layer RRC signaling also needs to additionally notify the index of its initial cyclic shift (AdditionalinitialCyclicShift), with a value range of 0 to 11; and the index of the orthogonal spreading code (Additionalinitial timeDomainOCC), with a value range of 0 to 6. Table 4 shows the orthogonal spreading code sequences of PUCCH format 1.

[0090] Table 4 Orthogonal spreading code sequences of PUCCH format 1

[0091]

[0092] Figure 4 Schematic diagram of uplink transmission and initial cyclic shift index and orthogonal spreading code index provided for an embodiment. As Figure 4 shown, when the UE uses PUCCH format 1 for transmission and the target resources indicated by DCI contain two spatial relationships, the UE is indicated two different initialCyclicShift values and timeDomainOCC values associated with different TRPs. For PUCCH format 1, the following method can be used but is not limited to it. The values indicated by initialCyclicShift and timeDomainOCC correspond to the beam sent to TRP0; the values indicated by the parameters AdditionalinitialCyclicShift and AdditionaltimeDomainOCC correspond to the beam sent to TRP1.

[0093] 3) For PUCCH format 2, format 3, or format 4, when transmitting using PUCCH format 2, format 3, or format 4, the original information bit sequence will go through steps such as channel coding, scrambling, discrete Fourier transform (only for PUCCH format 3 and format 4), modulation, etc., and then be mapped onto resource blocks for transmission. The coded bits are scrambled by a scrambling sequence, and the scrambling sequence is initialized according to the scrambling sequence parameter n ID ∈ {0, 1,..., 1023}, and n ID is configured by a higher layer parameter (dataScramblingIdentityPUSCH).

[0094] Figure 5 A schematic diagram of uplink transmission and scrambling sequence parameters provided for an embodiment is shown in Figure 5 the figure. When multiple beams are configured for PUCCH and transmitting to a Multi-TRP, multiple values should be indicated. For example, the value corresponding to the original parameter (the value indicated by dataScramblingIdentityPUSCH) is sent to the beam of TRP0; the value indicated by the parameter (AdditionaldataScramblingIdentity) is sent to the beam of TRP1.

[0095] In an embodiment, when the target resource corresponds to at least two spatial relationships, the terminal supports using one or more uplink transmission beams; when the target resource corresponds to one spatial relationship, the terminal supports using one uplink transmission beam.

[0096] In this embodiment, the UE supports uplink transmission through multiple beams to obtain spatial hierarchical gain. Which beam to specifically use for transmission or reception depends on the beam indication in beam management. In the case where the serving node performs downlink transmission using analog beamforming, the serving node needs to indicate the sequence number of the downlink analog transmission beam selected by the UE. After receiving the indication, the UE calls the best receiving beam corresponding to this sequence number for downlink reception according to the information stored during the beam training pairing process; in the case where the serving node schedules the UE to perform uplink transmission using analog beamforming, the serving node needs to indicate the auxiliary information of the uplink analog transmission beam of the UE. After receiving the auxiliary information, the UE performs uplink transmission according to the uplink analog transmission beam indicated by the base station, and the base station can call the receiving beam corresponding to this transmission beam for uplink reception according to the information stored during the beam training pairing process. For the uplink beam indication of PUCCH, first, the PUCCH radio resources are configured, and different PUCCH resources are semi-statically configured with different transmission beam directions. By selecting the PUCCH radio resources, different transmission beam directions are selected to achieve beam switching in multiple directions.

[0097] In one embodiment, the target resource is one; the indication information is used for at least one of the following:

[0098] When the target resource indicated by DCI corresponds to S spatial relations, S is greater than or equal to 2, and the repetition transmission count N is greater than 1, it indicates that the terminal uses L (2 ≤ L ≤ S) transmission beams to perform N uplink transmissions N times on N time slots, and the starting symbols and durations of the N uplink transmissions are the same; when the target resource indicated by DCI corresponds to S spatial relations, S is greater than or equal to 2, and the repetition transmission count N is equal to 1, it indicates that the terminal uses L (2 ≤ L ≤ S) transmission beams to perform L uplink transmissions L times on different frequency domains of the same time slot, and the starting symbols and durations of the L uplink transmissions are the same; when the target resource indicated by DCI corresponds to one spatial relation, and the repetition transmission count N is greater than 1, it indicates that the terminal uses the same transmission beam to perform N uplink transmissions N times on N time slots, and the starting symbols and durations of the N uplink transmissions are the same; when the target resource indicated by DCI corresponds to one spatial relation, and the repetition transmission count is equal to 1, it indicates that the terminal uses the same transmission beam to perform one uplink transmission on the same time slot.

[0099] In this embodiment, the serving node indicates the multiplexing mode of a target resource in the case of PUCCH Repetition to the terminal, and supports the frequency division multiplexing (FDM) of PUCCH, so as to obtain the frequency grading gain. Specifically, it can be divided into the following four cases:

[0100] 1) The target resource indicated by DCI corresponds to multiple spatial relations, and the repetition transmission count N is greater than 1. In this case, it indicates that the UE sends multiple PUCCHs (TDM) on different time slots according to the repetition transmission count indicated by the second high-layer parameter, and uses multiple transmission beams. Taking the target resource including two spatial relations as an example, Figure 6 FIG. is a schematic diagram of using two beams to perform uplink transmission on multiple time slots provided for an embodiment. As Figure 6 shown, the starting symbols and durations of PUCCH on different time slots are the same.

[0101] 2) The target resource indicated by DCI corresponds to multiple spatial relations, and the repetition transmission count N is equal to 1. In this case, the UE sends multiple PUCCHs (FDM) on the same time slot according to the number of spatial relations corresponding to the uplink control channel resource indicated by DCI, and uses multiple transmission beams. Taking the target resource including two spatial relations as an example, Figure 7 FIG. is a schematic diagram of using two beams to perform uplink transmission on the same time slot provided for an embodiment, as Figure 7 shown, the starting symbols and durations of each uplink transmission are the same.

[0102] 3) When the target resource indicated by the DCI corresponds to a spatial relationship and the repetition transmission count N is greater than 1, in this case, the UE is instructed to send multiple PUCCHs (TDM) on different time slots according to the repetition transmission count indicated by the second higher layer parameter, and use the same transmission beam. Figure 8 Schematic diagram for sending an uplink transmission using one beam on different time slots in an embodiment, as Figure 8 shown, the starting symbols and durations of the PUCCHs on different time slots are the same.

[0103] 4) When the target resource indicated by the DCI corresponds to a spatial relationship and the repetition transmission count N is equal to 1, in this case, the UE is instructed to send one PUCCH on one time slot according to the repetition transmission count indicated by the second higher layer parameter.

[0104] In an embodiment, the number of target resources is M, M is greater than or equal to 2; the indication information is used for at least one of the following:

[0105] When each target resource contains a spatial relationship, the time domain symbols of each target resource do not overlap, and the repetition transmission count N is equal to 1, the terminal is instructed to use L (2 ≤ L ≤ M) transmission beams to send L uplink transmissions on different symbols in the same time slot; when each target resource contains a spatial relationship, the time domain symbols of each target resource overlap, and the repetition transmission count N is equal to 1, the terminal is instructed to use L (2 ≤ L ≤ S) transmission beams to send L uplink transmissions on different frequency domains in the same time slot; when each target resource contains a spatial relationship, the time domain symbols of each target resource do not overlap, and the repetition transmission count N is greater than 1, the terminal is instructed to use L (2 ≤ L ≤ M) transmission beams to send L uplink transmissions on different symbols in the same time slot and perform N - time repetition transmissions on N time slots; when each target resource contains a spatial relationship, the time domain symbols of each target resource overlap, and the repetition transmission count N is greater than 1, the terminal is instructed to use L (2 ≤ L ≤ S) transmission beams to send M uplink transmissions on different frequency domains in the same time slot and perform N - time repetition transmissions on N time slots; when each target resource contains a spatial relationship and the repetition transmission count N is greater than 1, regardless of whether the time domain symbols of the target resources overlap or not, the terminal is instructed to use L (2 ≤ L ≤ S) transmission beams to perform N - time repetition transmissions on N time slots, and the starting symbols and durations of the N uplink transmissions are the same or different.

[0106] In this embodiment, the serving node indicates to the terminal the multiplexing manner of multiple target resources in the case of PUCCH Repetition, and supports frequency division multiplexing of PUCCH, so as to obtain frequency grading gain. Taking the number of target resources as two as an example, it can be specifically divided into the following five cases:

[0107] 1) Each of the two target resources indicated by DCI contains a spatial relationship, the time-domain symbols of each target resource do not overlap, and the repetition transmission times N is equal to 1. In this case, the UE is instructed to use two transmission beams to send two uplink transmissions on different symbols in the same time slot. Figure 9 It is a schematic diagram of sending uplink transmissions on different symbols in the same time slot provided for an embodiment, as Figure 9 shown, supporting time division multiplexing within a time slot.

[0108] 2) Each of the two target resources indicated by DCI contains a spatial relationship, the time-domain symbols of each target resource overlap, and the repetition transmission times N is equal to 1. In this case, the UE is instructed to use two transmission beams to send two uplink transmissions in different frequency domains in the same time slot. Figure 10 It is a schematic diagram of sending uplink transmissions in different frequency domains in the same time slot provided for an embodiment, as Figure 10 shown, supporting frequency division multiplexing.

[0109] 3) Each of the two target resources indicated by DCI contains a spatial relationship, the time-domain symbols of each target resource do not overlap, and the repetition transmission times N is greater than 1. In this case, the UE is instructed to use two transmission beams to send two uplink transmissions on different symbols in the same time slot, and perform N times of repetition transmissions in N time slots. Figure 11 It is a schematic diagram of sending uplink transmissions on different symbols in multiple time slots provided for an embodiment.

[0110] 4) Each of the two target resources indicated by DCI contains a spatial relationship, the time-domain symbols of each target resource overlap, and the repetition transmission times N is greater than 1.

[0111] 5) Each of the two target resources indicated by DCI contains a spatial relationship, and the repetition transmission times N is greater than 1. In this case, regardless of whether the time-domain symbols of each target resource overlap, the UE is instructed to use two transmission beams to perform N times of repetition transmissions in N time slots, and the start symbols and durations of the N uplink transmissions are the same or different. Figure 13Schematic diagram of uplink transmission in different frequency domains in multiple time slots provided for another embodiment, where (a) shows the case where time domain symbols of the target resource overlap; (b) shows the case where time domain symbols of the target resource do not overlap.

[0112] The indication method of the above embodiment aims to improve the reliability of uplink transmission in Multi-TRP or Multi panel. First, for the case of configuring multiple beams, it solves the problem of power mismatch of other beams when the serving node has only one power adjustment factor. Specifically, in the case where there are performance gaps among multiple beams, for example, when other transmission beams are enabled to prevent blocking, if only one TPC is notified by DCI at this time, it may only match one of the transmission beams, resulting in a mismatch problem with another transmission beam. The above embodiment considers the method for determining the power parameters of other beams in this case and expands the TPC command field in DCI.

[0113] Secondly, the payload size of DCI is semi-statically indicated by the first high-layer parameter, and the repetition times and the target resource (including one or more spatial relationships) are indicated, clarifying the number of bits of each control information in DCI, and jointly determining whether the extended TPC command field is used to expand the number of extended TPC commands or the range of the original TPC indication value, providing a reliable basis for the power control of the UE's uplink transmission.

[0114] In addition, in the case where the UE is instructed to send uplink transmission using multiple beams, different beams can be sent to two TRPs respectively. By adding corresponding indication parameters to the multiple beams, interference between TRPs caused by using the same cyclic shift and scrambling sequence in the same target resource is avoided, improving the transmission performance and reliability.

[0115] Finally, frequency division multiplexing and time division multiplexing (TDM) within a time slot in the case of supporting PUCCH repetition are supported, enabling the uplink transmission to obtain frequency grading gain.

[0116] In the embodiment of the present application, an uplink transmission method is further provided, which is applied to a terminal. The terminal determines the resource configuration for sending uplink transmission by receiving indication information, and accordingly sends uplink transmission, providing flexibility and reliability for uplink transmission. It should be noted that the specific operations performed by the terminal in this embodiment correspond to the specific operations performed by the serving node in the above embodiment. Technical details not described in detail in this embodiment can be referred to any of the above embodiments.

[0117] Figure 14 Flowchart of an uplink transmission method provided for an embodiment, as Figure 14 shown, the method provided in this embodiment includes step 210 and step 220.

[0118] In step 210, indication information is received, and the indication information is used to indicate the resource configuration for uplink transmission.

[0119] In step 220, uplink control information is sent according to the indication information.

[0120] In this embodiment, the serving node is, for example, a base station, and the terminal is, for example, a user equipment (UE). The resource configuration may include a resource set available to the terminal, a resource for sending uplink transmission, the spatial relationship included in the resource, the number of repeated transmissions of the uplink control channel, and the sending manner of the uplink transmission, etc., and is used to indicate the resource used by the terminal to send uplink transmission and the specific transmission manner. UCI is a signaling for uplink transmission sent by the terminal to the serving node. The terminal may send UCI to multiple TRPs (such as multiple base stations). The serving node indicates multiple resource configurations to the terminal, respectively corresponding to the paths between the terminal and multiple TRPs.

[0121] In one embodiment, the terminal is configured with at least one uplink control channel resource set, and each uplink control channel resource set contains at least one uplink transmission resource; each uplink transmission resource corresponds to at least one spatial relationship.

[0122] In one embodiment, the indication information includes DCI; the uplink control channel resource indication field in DCI is used to indicate the target resource, and the target resource is the uplink transmission resource used by the terminal to send UCI, and the target resource contains at least one spatial relationship.

[0123] In one embodiment, the indication information includes DCI; the extended TPC command field in DCI is used to adjust the uplink transmission power of the terminal to send UCI; the extended TPC command field is used to extend the range of the original TPC indication value or the number of extended TPC command fields; the function of the extended TPC command field is determined according to the number of spatial relationships included in the target resource and the number of repeated transmissions of the uplink control channel.

[0124] In this embodiment, the terminal can determine an uplink control channel resource set from the configured resource sets according to the number of UCI bits to be transmitted, then determine the target resource for sending UCI according to the uplink control channel resource indication field in DCI, use the target resource for the uplink transmission of UCI, and perform corresponding adjustment on the power of the transmission beam according to the extended TPC command field in DCI. Among them, the extended TPC command field is used to extend the range of the original TPC indication value or the number of extended TPC command fields, and the terminal jointly determines the function of the extended TPC command field according to the number of spatial relationships included in the target resource and the number of repeated transmissions.

[0125] In one embodiment, it further includes:

[0126] Step 201: Receive a first high-layer parameter and determine the number of bits of the extended TPC command field in the DCI according to the first high-layer parameter.

[0127] In this embodiment, the first high-layer parameter (DCI-PayloadSize) is configured semi-statically and notifies the UE of the payload size of the DCI to be received, so as to indicate the number of bits of the TPC command field in the DCI. Thus, the UE can extract the corresponding transmission power control indication information from the received DCI. After the UE determines the number of bits of the TPC command field, it is still unable to determine whether these bits belong to one or multiple fields, nor can it determine whether these bits are used to indicate the TPC of one or multiple beams. It is also necessary to jointly determine according to the number of spatial relationships included in the target resource indicated by the serving node and the indicated number of repeated transmissions.

[0128] In one embodiment, it further includes:

[0129] Step 202: Receive a second high-layer parameter and determine the number of repeated transmissions N of the uplink transmission according to the second high-layer parameter.

[0130] In one embodiment, when the target resource includes at least two spatial relationships and the number of repeated transmissions is equal to 1, the extended TPC command field in the DCI is used to extend the original TPC indication value range and is used to adjust the uplink transmission power corresponding to the spatial relationship used for the uplink transmission;

[0131] When the target resource corresponds to at least two spatial relationships and the number of repeated transmissions is greater than 1, the extended TPC command field is used to extend the number of TPC fields and is used to adjust the uplink transmission power corresponding to the spatial relationships used for multiple uplink transmissions;

[0132] When the target resource corresponds to one spatial relationship, the extended TPC command field in the DCI is used to extend the original TPC indication value range and is used to adjust the uplink transmission power corresponding to this spatial relationship.

[0133] In this embodiment, first, for the case where the target resource includes multiple spatial relationships, the UE supports sending UCI using multiple beams. In this case, it is also necessary to determine whether the extended TPC command field is used to extend the original TPC indication value range or to extend the number of TPC command fields according to the number of repeated transmissions N configured by the second high-layer parameter.

[0134] In one embodiment, it further includes:

[0135] Step 211: Determine the starting symbol position, duration, and physical resource block index of the target resource according to the uplink control channel resource indication field in the DCI;

[0136] The spatial relationship satisfies at least one of the following:

[0137] For uplink control channel format 0, when the target resource indicated by the DCI corresponds to at least two spatial relationships, different initial cyclic shifts are configured for different spatial relationships of the target resource;

[0138] For uplink control channel format 1, when the target resource indicated by the DCI corresponds to at least two spatial relationships, different initial cyclic shifts and orthogonal spreading codes are configured for different spatial relationships of the target resource;

[0139] For uplink control channel formats 2, 3, or 4, when the target resource indicated by the DCI corresponds to at least two spatial relationships, different scrambling sequence parameters are configured for different spatial relationships of the target resource.

[0140] In this embodiment, the UE can use multiple beams to send uplink transmissions to multiple TRPs. Taking two TRPs (TRP0 and TRP1 respectively) as an example, the cells corresponding to these two TRPs may be different, and the corresponding users may also be different. If the same cyclic shift and scrambling sequence in the same target resource are used for different beams, it will cause interference with users under another TRP and reduce the transmission performance. In this embodiment, during the process of the serving node indicating the target resource to the UE, in addition to indicating the starting symbol position, duration, and physical resource block index of the target resource, additional parameters are also indicated for different PUCCH formats to distinguish the transmission paths and beams of different TRPs. The UE performs uplink transmission accordingly to avoid interference between different paths and improve the reliability of multi-TRP transmission.

[0141] In one embodiment, when the target resource corresponds to at least two spatial relationships, the terminal supports using one or more beams for uplink transmission;

[0142] When the target resource corresponds to one spatial relationship, the terminal supports using one beam for uplink transmission.

[0143] In one embodiment, the target resource is one;

[0144] Step 220 includes at least one of the following:

[0145] When the target resource indicated by the DCI corresponds to S spatial relationships, S is greater than or equal to 2, and the number of repeated transmissions N is greater than 1, use L transmission beams to send at least two N - times uplink transmissions on N time slots, and the starting symbols and durations of the N - times uplink transmissions are the same;

[0146] When the target resource indicated by the DCI corresponds to S spatial relations, where S is greater than or equal to 2, and the number of repeated transmissions N is equal to 1, L (2 ≤ L ≤ S) transmission beams are used to send L uplink transmissions L times in different frequency domains within the same time slot, and the starting symbols and durations of the L transmissions are the same;

[0147] When the target resource indicated by the DCI corresponds to one spatial relation, and the number of repeated transmissions N is greater than 1, the same transmission beam is used to send N uplink transmissions N times in N time slots, and the starting symbols and durations of the N uplink transmissions are the same;

[0148] When the target resource indicated by the DCI corresponds to one spatial relation, and the number of repeated transmissions is equal to 1, the same transmission beam is used to send one uplink transmission in the same time slot.

[0149] In this embodiment, the serving node indicates to the terminal the multiplexing mode of a target resource in the case of PUCCH Repetition, and supports the frequency division multiplexing (FDM) of PUCCH, so as to obtain the frequency grading gain.

[0150] In one embodiment, the number of target resources is M, where M is greater than or equal to 2;

[0151] Step 220 includes at least one of the following:

[0152] When each target resource contains one spatial relation, the time domain symbols of each target resource do not overlap, and the number of repeated transmissions N is equal to 1, L (2 ≤ L ≤ S) transmission beams are used to send L uplink transmissions in different symbols within the same time slot;

[0153] When each target resource contains one spatial relation, the time domain symbols of each target resource overlap, and the number of repeated transmissions N is equal to 1, L (2 ≤ L ≤ S) transmission beams are used to send L uplink transmissions in different frequency domains within the same time slot;

[0154] When each target resource contains one spatial relation, the time domain symbols of each target resource do not overlap, and the number of repeated transmissions N is greater than 1, L (2 ≤ L ≤ S) transmission beams are used to send L uplink transmissions in different symbols within the same time slot, and N repeated transmissions are performed in N time slots;

[0155] When each target resource includes a spatial relationship, the time-domain symbols of the target resources overlap, and the number of repeated transmissions N is greater than 1, L (2 ≤ L ≤ S) transmission beams are used to perform L uplink transmissions in different frequency domains in the same time slot, and N repeated transmissions are performed in N time slots.

[0156] When each target resource includes a spatial relationship and the number of repeated transmissions N is greater than 1, the time-domain symbols of the target resources may or may not overlap. It is indicated that the terminal uses L (2 ≤ L ≤ S) transmission beams to perform N repeated transmissions in N time slots, and the start symbols and durations of the N uplink transmissions may be the same or different.

[0157] In this embodiment, the serving node indicates the multiplexing method of multiple target resources in the case of PUCCH Repetition to the terminal, and supports frequency-division multiplexing of PUCCH, so as to obtain frequency-level gain.

[0158] The uplink transmission method of the above embodiment aims to improve the reliability of uplink transmission in Multi-TRP or Multi panel. First, for the case of configuring multiple beams, the TPC field in DCI is extended, and the terminal obtains the extended TPC command field by receiving indication information;

[0159] Secondly, the terminal determines the payload size of DCI by receiving the first high-layer parameter, and according to the number of repeated transmissions and the target resources (including one or more spatial relationships), determines the number of bits of each control information in DCI, and jointly determines whether the extended TPC command field is used for the number of extended TPC command fields or to extend the range of the original TPC indication value, and accordingly sends uplink transmission to improve the reliability of uplink transmission;

[0160] In addition, when the terminal is instructed to send uplink transmission with multiple beams, different beams can be sent to two TRPs respectively. For different beams, uplink transmission is sent according to the increased indication parameters, avoiding interference between TRPs caused by using the same cyclic shift and scrambling sequence in the same target resource, and improving the transmission performance and reliability; finally, frequency-division multiplexing and time-division multiplexing (TDM) within a time slot in the case of supporting PUCCH repetition are supported, so that the uplink transmission obtains frequency-level gain.
