In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application. The embodiments of this application include at least part of the following contents.

In order to facilitate a better understanding of the embodiments of the present application, an explanation will be given on how the Physical Uplink Shared Channel (PUSCH) related to this application carries aperiodic channel state information (A-CSI) in the case of repeated transmission. .

When A-CSI needs to be multiplexed into multiple PUSCH repeated transmissions, the multiplexing method is: PUSCH repetition type A and PUSCH repetition type B. Specifically, as shown in Figure 2, PUSCH repetition type A (slot-based PUSCH repetition transmission): two sets of PUSCH (the same or different redundancy versions (the same or different redundancy versions) are transmitted at the same symbol position in K consecutive time slots) Redundancy Version, RV) version), each group of PUSCH is associated with a TCI status. PUSCH repetition type B (mini-slot-based PUSCH repetition transmission): Two sets of PUSCH (same or different RV versions) are sent at K transmission opportunities, and each set of PUSCH is associated with a TCI state.

For PUSCH repetition type A, the CSI report is multiplexed on the first transmitted PUSCH only; for PUSCH repetition type B, the CSI report is multiplexed on the first actual repetition, and the terminal device does not expect the first actual repeated PUSCH The number of time domain symbols is 1 symbol.

In PUSCH repeated transmission in a multiple Transmission Reception Point (TRP) scenario, two different beams are introduced for repeated transmission of uplink data. The specific mapping method can be a cyclic mapping method and a sequential mapping method. In order to obtain frequency diversity gain, for PUSCH repetition type A, A-CSI is multiplexed to the first repeated transmission of beam 1 and the first repeated transmission of beam 2; for PUSCH repetition type B, A-CSI is multiplexed to beam 1 The first actual transmission of and the first actual transmission of beam 2.

It should be noted that multi-TRP transmission means that on the same carrier, multiple TRPs can communicate with a terminal at the same time.

In order to facilitate a better understanding of the embodiments of this application, the calculation time of the channel state information (Channel State Information, CSI) related to this application is explained.

NR defines two CSI calculation-related capabilities of the terminal. The time interval between the last symbol of the Physical Downlink Control Channel (PDCCH) carrying the CSI request message and the first symbol of the PUSCH carrying the CSI report is greater than or equal to the first calculation time. The time interval between the last symbol of the CSI measurement resource and the first symbol of the PUSCH carrying the CSI report is greater than or equal to the second calculation time. The CSI report may be the mth updated CSI report, or may include all updated CSI reports.

The first calculation time can be calculated based on the following formula 1, and the second calculation time can be calculated based on the following formula 2.

T _proc,CSI =(Z)(2048+144)·κ2 ^-μ ·T _C +T _switch formula 1

T' _proc,CSI =(Z')(2048+144)·κ2 ^-μ ·T _C formula 2

The value of Z can be shown as Z ₁ , Z ₂ , Z ₃ in the following Table 1 and Table 2, and the value of Z′ can be shown as Z ₁ ′, Z ₂ ′, Z ₃ ′ in the following Table 1 and Table 2.

Table 1 CSI calculation time capability 1

Table 2 CSI calculation time capability 1

When the terminal receives an aperiodic CSI request message, the terminal determines whether CSI calculation needs to be performed and whether to send a CSI report based on the time relationship between the PDCCH, associated CSI measurement resources and PUSCH, combined with its CSI calculation capabilities. Among them, an aperiodic CSI request can trigger one or more CSI calculations and reports. Each CSI report is associated with different CSI measurement resources, but all CSI reports are sent on the same PUSCH.

In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application will be described.

In PUSCH repetition type A and PUSCH repetition type B, the mapping method of A-CSI does not stipulate that frequency division multiplexing (Frequency-division multiplexing, FDM) or spatial division multiplexing (Spatial Division Multiplexing, SDM) or spatial division multiplexing (SDM) be used in PUSCH. How should A-CSI be multiplexed when the Single Frequency Network (SFN) solution uses two beams to transmit simultaneously. This patent considers a solution to this problem.

In addition, when the terminal uses two beams to transmit PUSCH through two antenna panels (panel) at the same time, the timing advance (Timing Advance, TA) may be different. Under the influence of different TA, the CSI calculation time may cause the first PUSCH and /Or the first symbol of the time domain resource position of the second PUSCH does not meet the CSI calculation time requirements, so the terminal behavior in this case needs to be redefined.

Based on the above problems, this application proposes a solution for transmitting CSI reports. The terminal device sends the CSI report on the first PUSCH and/or the second PUSCH, and when the first PUSCH and the second PUSCH are associated with different spatial parameters , the first PUSCH and/or the second PUSCH are sent using the FDM, SDM or SFN transmission scheme, thereby increasing the flexibility and reliability of CSI report transmission.

The technical solutions of the present application are described in detail below through specific examples.

S210, the network device sends the first DCI, where the first DCI includes the CSI request message;

S220, the terminal device receives the first DCI;

S230, the terminal equipment sends a CSI report on the first PUSCH and/or the second PUSCH; wherein the first PUSCH is associated with a first spatial parameter, the second PUSCH is associated with a second spatial parameter, and the first PUSCH and/or Or the second PUSCH is sent using FDM, SDM or SFN transmission scheme;

S240: The network device receives the CSI report sent on the first PUSCH and/or the second PUSCH.

In this embodiment of the present application, the terminal equipment sends the CSI report on the first PUSCH and/or the second PUSCH, and in the case where the first PUSCH and the second PUSCH are associated with different spatial parameters, the first PUSCH and/or the second PUSCH PUSCH is sent using FDM, SDM or SFN transmission scheme, thereby increasing the flexibility and reliability of CSI report transmission. That is to say, when multiple antenna panels (panels) transmit simultaneously, the CSI (such as A-CSI or SP-CSI) corresponding to different transmission schemes of PUSCH can be multiplexed in different ways, which increases the flexibility of CSI report transmission. The beams used to send CSI reports can improve reliability.

In the embodiment of this application, when multiple antenna panels (panels) transmit simultaneously, PUSCHs sent on different panels can be independently scheduled through the DCI of their respective TRPs. The TAs of the two panels/TRPs can be different. The TAs associated with different panels/TRPs can be The time domain resource position of PUSCH will be affected by TA. That is to say, the uplink timing of the first PUSCH and the second PUSCH may be different. Therefore, in the embodiment of the present application, the calculation time of CSI under the influence of TA and the multiplexing of PUSCH associated with different panels/TRPs are comprehensively considered. The terminal equipment The CSI report is sent on the first PUSCH and/or the second PUSCH. That is, the terminal equipment may give up sending the CSI report on the first PUSCH or the second PUSCH, or the terminal equipment may ignore the first DCI.
