[0032] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0033] In scenarios that support repeated transmission involving various complex factors such as space, time domain, frequency domain, and beam, there is a lack of effective mechanisms to uniformly and efficiently plan physical uplink channel transmission. Since the channel state information for physical uplink channel transmission cannot be accurately determined, the reliability of physical uplink channel transmission is low.

[0034] An information determination method is provided in an embodiment of the present application, which accurately determines the channel state information of each repeated transmission according to the indication information and transmits it accordingly to improve the reliability of physical uplink channel transmission.

[0035] Figure 1 1 is a flow chart of an information determination method provided by an embodiment. The information determination method of this embodiment can be applied to a first communication node, and the first communication node can be a user equipment (UE). Figure 1 As shown, the method of this embodiment includes step 110 and step 120.

[0036] In step 110, indication information is received.

[0037] In step 120, channel state information of M physical uplink channel transmissions is determined according to the indication information, where M is an integer greater than or equal to 1.

[0038] In this embodiment, the UE receives indication information from a second communication node (the second communication node is a service node, such as a base station), and performs M physical uplink channel transmissions according to the indication information, such as physical uplink shared channel (PUSCH) transmissions. The M physical uplink channel transmissions may be M physical uplink channel resources for transmitting physical uplink data, or a physical uplink channel resource at different transmission times, or different transmission carriers, a transmission on different transmission subbands, or transmissions on different layers. The M physical uplink channel transmissions correspond to a certain number of uplink transmission blocks, and the uplink transmission may be completed according to the uplink transmission blocks according to space, time domain, frequency domain, etc., so as to uniformly and efficiently perform physical uplink channel transmissions and improve the reliability of uplink transmission. The M physical uplink channel transmissions may correspond to different antenna panels of the UE, and the antenna panel may be a transmission receiving point or a communication node. Different antenna panels may be replaced by spatial parameters, such as a transmit beam, a receive beam, a spatial transmission filter, a quasi-co-location type D, etc. The spatial transmission filter in the present application determines the transmit beam and the receive beam direction on the antenna panel. For example, PUSCH transmissions corresponding to the same spatial transmission filter may be transmitted by the same antenna panel, that is, PUSCH transmissions corresponding to the same spatial transmission filter have the same transmission beam direction.

[0039] In one embodiment, the indication information includes at least one of the following: a transmission scheme indication; a time-frequency domain resource indication; a transmission block number indication, and the time-frequency domain resource indication and the transmission block number indication correspond to the transmission scheme indication respectively; the channel state information includes at least one of the following: a time-frequency domain resource indication; a transmission block number indication; a spatial transmission filter; a redundancy version (Redundancy Version, RV) RV; a transmitted uplink precoding matrix indication information (Transmitted Precoding Matrix Indicator, TPMI); a demodulation reference signal (Demodulation Reference Signal, DMRS) port; a modulation and coding scheme (Modulation and Coding Scheme, MCS); and a power control parameter.

[0040] In this embodiment, the transmission scheme indication is used to indicate the transmission scheme of the physical uplink channel transmission, thereby correspondingly indicating the number of transmission blocks, the correspondence between M physical uplink channel transmissions and the transmission blocks, the time-frequency domain resources occupied by each physical uplink channel transmission, etc., so that the UE can accurately determine the channel state information and perform physical uplink channel transmission.

[0041] In one embodiment, the indication information is indicated by at least one of the following information fields: Radio Resource Control (RRC) signaling; Media Access Control-Control Element (MAC-CE); Downlink Control Information (DCI).

[0042] In one embodiment, when the transmission scheme is indicated as the first transmission scheme, the corresponding number of transmission blocks is indicated as 1, and the corresponding time-frequency domain resources are indicated as follows: M physical uplink channel transmissions correspond to the same time domain resources; each physical uplink channel transmission corresponds to a segment of frequency domain resources, and the frequency domain resources do not overlap.

[0043] In this embodiment, M physical uplink channel transmissions correspond to one uplink transmission block, and the M physical uplink channel transmissions occupy the same time domain resources and different frequency domain resources. Specifically, the M physical uplink channel transmissions correspond to M non-overlapping frequency domain resources.

[0044] In one embodiment, in one embodiment, when the transmission scheme is indicated as the second transmission scheme, the corresponding number of transmission blocks is indicated as M, and the corresponding time-frequency domain resources are indicated as follows: the M physical uplink channel transmissions correspond to M identical uplink transmission blocks; the M physical uplink channel transmissions correspond to the same time domain resources and the same frequency domain resources; each uplink transmission block corresponds to one or more layers of transmission.

[0045] In this embodiment, M physical uplink channel transmissions correspond to M identical uplink transmission blocks. The uplink transmission block may also be referred to as transmission information, such as information before channel coding, or a coding block in uplink information, or a large coding block corresponding to multiple sub-coding blocks. M identical uplink transmission blocks mean that the M uplink transmission blocks carry exactly the same information to be transmitted, that is, the M uplink transmission blocks are repeatedly transmitted. The M physical uplink channel transmissions occupy the same time domain resources and the same frequency domain resources, and each uplink transmission block corresponds to one or more layers of transmission.

[0046] In one embodiment, when the transmission scheme is indicated as the third transmission scheme, the corresponding number of transmission blocks is indicated as M, and the corresponding time-frequency domain resources are indicated as follows: M physical uplink channel transmissions correspond to M identical uplink transmission blocks; M physical uplink channel transmissions correspond to the same time domain resources; each physical uplink channel transmission corresponds to a segment of frequency domain resources, and the segments of frequency domain resources do not overlap.

[0047] In this embodiment, M physical uplink channel transmissions correspond to M identical uplink transmission blocks, and the M physical uplink channel transmissions occupy the same time domain resources and different frequency domain resources. Specifically, the M physical uplink channel transmissions correspond to M non-overlapping frequency domain resources.

[0048] In one embodiment, in one embodiment, when the transmission scheme is indicated as the fourth transmission scheme, the corresponding number of transmission blocks is indicated as M, and the corresponding time-frequency domain resources are indicated as follows: M physical uplink channel transmissions correspond to M identical uplink transmission blocks; each physical uplink channel transmission corresponds to a segment of time domain resources, and the segments of time domain resources do not overlap; the M physical uplink channel transmissions correspond to N segments of frequency domain resources, and the segments of frequency domain resources do not overlap, wherein N is an integer greater than or equal to 1 and N is an integer less than or equal to M.

[0049] In this embodiment, M physical uplink channel transmissions correspond to M identical uplink transmission blocks, that is, the M uplink transmission blocks are repeatedly transmitted. The M physical uplink channel transmissions occupy different time domain resources and N non-overlapping frequency domain resources, where 1≤N≤M. When N=1, the M physical uplink channel transmissions correspond to the same frequency domain resources; when N=M, the M physical uplink channel transmissions correspond to non-overlapping frequency domain resources; when 1<N<M, the frequency domain resources corresponding to the M physical uplink channel transmissions may be identical or non-overlapping.

[0050] In some embodiments, N is the number of spatial transmission filters, that is, M physical uplink channel transmissions correspond to N spatial transmission filters.

[0051] In one embodiment, when the transmission scheme is indicated as the fifth transmission scheme, the corresponding number of transmission blocks is indicated as M, and the corresponding time-frequency domain resources are indicated as follows: M physical uplink channel transmissions correspond to M identical uplink transmission blocks; M physical uplink channel transmissions correspond to the same frequency domain resources; each physical uplink channel transmission corresponds to a segment of time domain resources, and the segments of time domain resources do not overlap.

[0052] In this embodiment, the M physical uplink channel transmissions correspond to M identical uplink transmission blocks, and the M physical uplink channel transmissions occupy the same frequency domain resources and different time domain resources. Specifically, the M physical uplink channel transmissions correspond to M non-overlapping time domain resources.

[0053] In one embodiment, the frequency domain resources for M physical uplink channel transmissions include a first frequency domain resource and a second frequency domain resource; the frequency domain resources for M physical uplink channel transmissions correspond to a first frequency offset and a second frequency offset; wherein the first frequency offset is the difference between the starting frequency of the second frequency domain resource and the starting frequency of the first frequency domain resource, and the second frequency offset is the difference between the starting frequency of the first frequency domain resource and the starting frequency of the bandwidth part (Bandwidth Part, BWP).

[0054] In this embodiment, the frequency domain resources for the M physical uplink channel transmissions are divided into two parts: a first frequency domain resource and a second frequency domain resource. There is a first frequency offset X between the two frequency domain resources (the starting frequencies thereof). offset There is a second frequency offset X between the starting frequency of the first frequency domain resource and the starting frequency of the BWP start .

[0055] In one embodiment, when the second frequency offset is not 0 and there is at least one physical uplink channel transmission whose frequency range exceeds the boundary of the BWP, the frequency portion exceeding the boundary is transmitted through a target frequency band of the BWP, wherein the target frequency band includes a frequency band between the starting frequency of the BWP and the starting frequency of the first frequency domain resources.

[0056] In this embodiment, the X after the starting frequency of BWP start is the starting frequency of the first frequency domain resource, and the X after the starting frequency of the first frequency domain resource offset is the starting frequency of the second frequency domain resource, if X start is not 0, and because X start and X offset The existence of X causes the frequency range of the subsequent physical uplink channel transmission to exceed the boundary of BWP. start The part of the frequency band that exceeds the boundary is transmitted (the part that exceeds the boundary may be a physical uplink channel transmission, or there may be multiple physical uplink channel transmissions that exceed the boundary), thereby improving resource utilization and improving the reliability of uplink transmission.

[0057] In one embodiment, the M physical uplink channel transmissions correspond to the same MCS.

[0058] In one embodiment, M physical uplink channel transmissions correspond to the same DMRS port; or, M physical uplink channel transmissions correspond to M different DMRS ports, where M is greater than or equal to 2.

[0059] In one embodiment, M physical uplink channel transmissions correspond to the same TPMI; or, physical uplink channel transmissions corresponding to the same spatial transmission filter correspond to the same TPMI; or, each physical uplink channel transmission corresponds to a TPMI in sequence, and each TPMI is cyclically arranged according to the order of the codebook table.

[0060] In this embodiment, there are three types of corresponding relationships between M physical uplink channel transmissions and TPMI, wherein each physical uplink channel transmission corresponds to a TPMI in turn, and each TPMI is arranged cyclically in the order of the code book table, which means that the UE can poll and select TPMI corresponding to M physical uplink channel transmissions in turn according to the TPMI given in the code book table and its arrangement order. For example, in Table 7.3.1.1.2-3 in 38.212, if the UE antenna attribute is partial antenna-related transmission, the base station indicates the starting index value 4 to the UE, corresponding to TPMI=4, then the UE selects the TPMI index value in turn according to the order of the "antenna non-related and partially related" column in the middle of the table, applies TPMI=4 to the first PUSCH transmission, applies TPMI=5 to the second PUSCH transmission, and so on.

[0061] In one embodiment, M physical uplink channel transmissions correspond to the same RV; or, physical uplink channel transmissions corresponding to the same spatial transmission filter correspond to the same RV; or, each physical uplink channel transmission corresponds to one RV in turn, and the RVs are arranged cyclically in a set order.

[0062] In this embodiment, there are three types of correspondences between M physical uplink channel transmissions and RVs, wherein each physical uplink channel transmission corresponds to one RV in turn, and each RV is arranged cyclically in a set order, which means that the UE can poll and select RVs corresponding to M physical uplink channel transmissions in turn according to the set order of RVs (for example, 0-2-3-1). For example, the first physical uplink channel transmission corresponds to RV 1, the second physical uplink channel transmission corresponds to RV 2, the third physical uplink channel transmission corresponds to RV 3, the fourth physical uplink channel transmission corresponds to RV 4, the fifth physical uplink channel transmission corresponds to RV1, and so on.

[0063] In one embodiment, M physical uplink channel transmissions correspond to N spatial transmission filters, and the M physical uplink channel transmissions correspond to N sets of power control parameters, where N is an integer greater than or equal to 1 and N is an integer less than or equal to M. The N spatial transmission filters are determined according to one of the following: Transmission Configuration Indication (TCI) state; Quasi-Co-Location (QCL); Sounding Reference Signal Resource Indicator (SRI); Spatial Relation Information; Sounding Reference Signal (SRS); Channel State Information Reference Signal (CSI-RS); Synchronization Signal Block (SSB).

[0064] In this embodiment, a set of power control parameters includes: an open-loop power control parameter (P0-PUSCH-AlphaSet), a path loss reference signal (PUSCH-Pathloss Reference Signal) and a closed-loop process parameter (twoPUSCH-PC-Adjustment States).

[0065] In one embodiment, the first X physical uplink channel transmissions among the M physical uplink channel transmissions correspond to the first Y spatial transmission filters, and the last X physical uplink channel transmissions correspond to the last Y spatial transmission filters; or, the odd-numbered physical uplink channel transmissions among the M physical uplink channel transmissions correspond to the first Y spatial transmission filters, and the even-numbered physical uplink channel transmissions correspond to the last Y spatial transmission filters; or, among the M physical uplink channel transmissions, every two physical uplink channel transmissions are taken as a group, the odd-numbered group corresponds to the first Y spatial transmission filters, and the even-numbered group of physical uplink channel transmissions corresponds to the last Y spatial transmission filters, wherein X is half of M, and Y is half of N.

[0066] In this embodiment, M physical uplink channel transmissions correspond to N spatial transmission filters, M≥N. The first M / 2 physical uplink channel transmissions correspond to the first N / 2 spatial transmission filters, and the last M / 2 physical uplink channel transmissions correspond to the last N / 2 spatial transmission filters; or, odd-numbered physical uplink channel transmissions correspond to the first N / 2 spatial transmission filters, and even-numbered physical uplink channel transmissions correspond to the last N / 2 spatial transmission filters; or, odd-numbered groups correspond to the first Y spatial transmission filters, and even-numbered groups of physical uplink channel transmissions correspond to the last Y spatial transmission filters, for example, the 1st, 2nd, 5th, 6th, ...M-3rd, M-2nd physical uplink channel transmissions correspond to the first Y spatial transmission filters, and the 3rd, 4th, 7th, 8th, ...M-1st, Mth transmissions correspond to the last Y spatial transmission filters.

[0067] In one embodiment, physical uplink channel transmissions corresponding to the same spatial transmission filter correspond to the same power control parameters.

[0068] Taking the physical uplink channel transmission as PUSCH transmission as an example, the method for determining information of M physical uplink channel transmissions is described through the following different examples.

[0069] Example 1:

[0070] In this example, M PUSCH transmissions correspond to M identical uplink transmission blocks, that is, the service node schedules the UE to perform M PUSCH repetitive transmissions on the M uplink transmission blocks, and the M uplink transmission blocks correspond to the M PUSCH transmissions one by one, and M≥1. The M PUSCH transmissions use the same time domain resources and frequency domain resources, and each uplink transmission block corresponds to one or more layers of transmission. In each example of the present application, the scheduling scheme is implemented in various ways, for example, a transmission scheme indication and an M value are configured in the PUSCH-Config structure in the RRC to indicate the scheduling scheme; or a transmission scheme indication and an M value are configured in the time domain resource allocation (TDRA) structure of the PUSCH in the RRC to indicate the scheduling scheme; or a pool of transmission scheme indications and M values ​​are configured in the PUSCH-Config structure, and a transmission scheme indication and an M value in the pool are selected by the TDRA domain or the frequency domain resource allocation (FDRA) domain of the DCI and applied to the PUSCH transmission scheduled by the DCI, etc.

[0071] In this example, M PUSCH transmissions correspond to a same MCS. M PUSCH transmissions may correspond to a DMRS port, or to M different DMRS ports. M PUSCH transmissions correspond to N different spatial transmission filters and N sets of power control parameters, 1≤N≤M.

[0072] In this example, the correspondence between M PUSCH transmissions and N spatial transmission filters can be one of the following: 1) the first M / 2 PUSCH transmissions correspond to the first N / 2 spatial transmission filters, and the last M / 2 PUSCH transmissions correspond to the last N / 2 spatial transmission filters; 2) odd-numbered PUSCH transmissions correspond to the first N / 2 spatial transmission filters, and even-numbered PUSCH transmissions correspond to the last N / 2 spatial transmission filters; 3) every two physical uplink channel transmissions are taken as a group, the odd-numbered group corresponds to the first Y spatial transmission filters, and the even-numbered group of physical uplink channel transmissions corresponds to the last Y spatial transmission filters.

[0073] PUSCH transmissions corresponding to the same spatial transmission filter correspond to the same power control parameters.

[0074] In this example, M PUSCH transmissions may correspond to the same TPMI; or, M PUSCH transmissions correspond to N TPMIs, and PUSCH transmissions corresponding to the same spatial transmission filter correspond to the same TPMI; or, the TPMI corresponding to each physical uplink channel transmission is determined by polling in the order of the codebook table.

[0075] In this example, M PUSCH transmissions may correspond to the same RV, in which case the number of RVs is 1; or, M PUSCH transmissions correspond to N RVs, the number of RVs is N, and PUSCH transmissions corresponding to the same spatial transmission filter correspond to the same RV; or, the RV corresponding to each physical uplink channel transmission is determined by polling in a set order, for example, selecting in sequence in the order of 0-2-3-1, in which case the number of RVs is min(M, 4).

[0076] Figure 2 FIG. 1 is a schematic diagram of space division multiplexing of M physical uplink transmissions provided by an embodiment. Figure 2 As shown, in the case of M=2 and N=2, the service node schedules the UE to perform two repeated PUSCH transmissions for two identical uplink transmission blocks, and the two PUSCH transmissions use the same time-frequency domain resources ( Figure 2 In the figure, the horizontal direction represents time domain resources, and the vertical direction represents frequency domain resources. Each PUSCH transmission corresponds to 1 layer of transmission. Figure 2In the present invention, each PUSCH transmission corresponds to the same MCS, and each PUSCH transmission corresponds to different DMRS ports, RV, TPMI, spatial transmission filter and power control parameters.

[0077] Example 2

[0078] In this example, M PUSCH transmissions correspond to one uplink transmission block, that is, the service node schedules the UE to divide one uplink transmission block into M PUSCH transmissions, and the data of each PUSCH transmission is different, M≥1. M PUSCH transmissions correspond to the same MCS. M PUSCH transmissions can correspond to one DMRS port, or to M different DMRS ports. M PUSCH transmissions correspond to N different spatial transmission filters and N sets of power control parameters, 1≤N≤M.

[0079] In this example, M PUSCH transmissions use the same time domain resources and different frequency domain resources.

[0080] In this example, the correspondence between M PUSCH transmissions and N spatial transmission filters can be one of the following: 1) the first M / 2 PUSCH transmissions correspond to the first N / 2 spatial transmission filters, and the last M / 2 PUSCH transmissions correspond to the last N / 2 spatial transmission filters; 2) odd-numbered PUSCH transmissions correspond to the first N / 2 spatial transmission filters, and even-numbered PUSCH transmissions correspond to the last N / 2 spatial transmission filters; 3) every two physical uplink channel transmissions are taken as a group, the odd-numbered group corresponds to the first Y spatial transmission filters, and the even-numbered group of physical uplink channel transmissions corresponds to the last Y spatial transmission filters.

[0081] PUSCH transmissions corresponding to the same spatial transmission filter correspond to the same power control parameters.

[0082] In this example, M PUSCH transmissions may correspond to the same TPMI; or, M PUSCH transmissions correspond to N TPMIs, and PUSCH transmissions corresponding to the same spatial transmission filter correspond to the same TPMI; or, the TPMI corresponding to each physical uplink channel transmission is determined by polling in the order of the codebook table.

[0083] In this example, M PUSCH transmissions may correspond to the same RV, in which case the number of RVs is 1; or, M PUSCH transmissions correspond to N RVs, the number of RVs is N, and PUSCH transmissions corresponding to the same spatial transmission filter correspond to the same RV; or, the RV corresponding to each physical uplink channel transmission is determined by polling in a set order, for example, selecting in sequence in the order of 0-2-3-1, in which case the number of RVs is min(M, 4).

[0084] In this example, the serving node may configure X between frequency domain resources for different PUSCH transmissions. offset , X offset is the difference between the starting frequency of the second frequency domain resource and the starting frequency of the first frequency domain resource, in, is the bandwidth of the currently activated BWP, is the bandwidth of each PUSCH transmission. Optionally, in some embodiments, the serving node configures X for the UE. start , represents the difference between the starting frequency of BWP and the starting frequency of the first frequency resource. start Not 0 and X offset If the frequency range of a PUSCH transmission exceeds the boundary of the BWP, the frequency portion exceeding the boundary can be at the starting position of the BWP 0 to X start Transmission within range.

Figure 3 As shown, in the case of M=2 and N=2, the service node schedules the UE to divide one uplink transmission block into two PUSCH transmissions. The two PUSCH transmissions use the same time domain resources (such as Figure 3 The vertical time slot resources in the middle), use different frequency domain resources (such as Figure 3 The two PUSCH transmissions correspond to the same RV, DMRS port and MCS. The two PUSCH transmissions correspond to two different spatial transmission filters, two different TPMIs and two sets of power control parameters. The frequency domain offset X is configured between the frequency domain resources of the two PUSCH transmissions. offset The frequency domain resource of the first PUSCH transmission is configured with X between the starting frequency of the uplink (Uplilnk, UL) BWP start .

[0086] Example 3

The M PUSCH transmissions correspond to the same MCS. In this example, the M PUSCH transmissions may correspond to one DMRS port, or to M different DMRS ports. The M PUSCH transmissions correspond to N different spatial transmission filters and N sets of power control parameters, 1≤N≤M.

[0088] In this example, M PUSCH transmissions use the same time domain resources and different frequency domain resources.

[0089] In this example, the correspondence between M PUSCH transmissions and N spatial transmission filters can be one of the following: 1) the first M / 2 PUSCH transmissions correspond to the first N / 2 spatial transmission filters, and the last M / 2 PUSCH transmissions correspond to the last N / 2 spatial transmission filters; 2) odd-numbered PUSCH transmissions correspond to the first N / 2 spatial transmission filters, and even-numbered PUSCH transmissions correspond to the last N / 2 spatial transmission filters; 3) every two physical uplink channel transmissions are taken as a group, the odd-numbered group corresponds to the first Y spatial transmission filters, and the even-numbered group of physical uplink channel transmissions corresponds to the last Y spatial transmission filters.
