[0134] According to another embodiment of the present application, a method for determining TA information is also provided, the method comprising the following steps:

[0139] The first channel or the first signal is a signal sent by the first communication node, and the second channel or the second signal is a signal received by the first communication node.

[0140] It should be added that establishing the association relationship between the first signal and the TA information includes at least one of the following: including the first signal information in the configuration information of the TA information; including the TA information in the configuration information of the first signal; determining the TA information according to the first signal information. The same is true for other association relationships.

[0141] The above technical solution is adopted to solve the problem in the related technology of lack of a solution to determine the TA value of the signal sent by the terminal in the multi-TRP transmission scenario, and the TA value can be determined subsequently based on the association relationship.

[0142] Optionally, the TA information is the basis for the first communication node to send the third channel or the third signal, or the TA information is the basis for the first communication node to send the first channel or the first signal.

[0143] Optionally, the method also includes: the first channel or the second channel or the third channel includes at least one of the following channels: a data channel, a control channel; the first signal or the third signal includes at least one of the following signals: a demodulation reference signal, a measurement reference signal, a random access signal; the second signal includes at least one of the following signals: a demodulation reference signal, a measurement reference signal, a synchronization signal, a measurement reference signal as a tracking reference signal TRS.

[0146] Step 1: The first communication node receives configuration information of a third signal sent by the second communication node, wherein the configuration information includes TA information;

[0147] Step 2: The first communication node sends the third signal according to the TA information.

[0150] Optionally, in the configuration information of the third signal, the TA information is jointly encoded with at least one of the following information: a spatial filtering parameter of the third signal; or a power parameter of the third signal.

[0151] The following is a description of the specific embodiments of the present application. Specific embodiment 1:

[0153] Multi-TRP transmission means that a terminal can simultaneously receive more than one PDSCH under one BWP, or the number of DMRS groups of a PDSCH is greater than 1, among which the demodulation reference signal ports in one DMRS group and the different demodulation reference signal ports satisfy the QCL relationship with respect to at least one type of quasi-co-site parameter, and different DMRSs in different DMRS groups do not satisfy the QCL relationship.

[0154] Specifically, taking two TRPs as an example, multi-TRP transmission is described, and specific scenarios are listed in Table 1, which is a schematic table of transmission scenarios under multiple TRPs according to the present application:

[0155] Table 1

[0156]

[0157] Figure 2 This is a transmission scenario diagram of a terminal receiving PDSCH sent by multiple TRPs according to this application Figure 1 ; Figure 3 This is a transmission scenario diagram of a terminal receiving PDSCH sent by multiple TRPs according to this application Figure 2 ; Figure 4 This is a transmission scenario diagram of a terminal receiving PDSCH sent by multiple TRPs according to this application Figure 3 ; Figure 5 This is a transmission scenario diagram of a terminal receiving PDSCH sent by multiple TRPs according to this application Figure 4 , Figure 6 This is a transmission scenario diagram of a terminal receiving PDSCH sent by multiple TRPs according to this application Figure 5 .like Figure 2-Figure 5 In the example, DCI1 schedules PDSCH1 and DCI2 schedules PDSCH2.

[0158] exist Figure 2In the example, there is no ideal backhaul between TRP1 and TRP2. They each independently schedule a terminal. When considering the different settings of TRP1 and TRP2, or considering the different UE groups they serve, a terminal can simultaneously receive PDSCH1 and PDSCH2 in a BWP in the same time unit. PDSCH1 is transmitted through TRP1, and PDSCH2 is transmitted through TRP2. The high-level configuration information corresponding to PDSCH1 and PDSCH2 can be different. Therefore, multiple PDSCHs and multiple PDCCHs can be included in one BWP, and the relationship between multiple PDSCHs and multiple PDCCHs included in the BWP is further configured. Therefore, when a PDSCH is scheduled in the DCI, the high-level parameters of the PDSCH are obtained through the configuration information of the PDSCH corresponding to the PDCCH where the DCI is located.

[0159] For example, configure as follows:

[0160]

[0161] The configuration information of PDCCH configures the CORESET, Searchspace and other information included in the PDCCH. The configuration information of PDSCH further configures the following information: scrambling information, demodulation reference signal information, TCI state pool, resource allocation information, rate matching information, MCS reference table information, precoding resource group information, rate matching information, etc. For example, a set of PDSCH configuration information may correspond to a PDSCH-Config in the configuration of 3Gpp standard version 38.331.V15.0.0: a set of PDCCH configuration information may correspond to a PDCCH-Config in the configuration of 3Gpp standard version 38.331.V15.0.0.

[0162] In the above manner, different TRPs correspond to different (PDCCH, PDSCH) combinations. This embodiment does not exclude that a BWP includes multiple PDSCHs and a PDCCH, and then a corresponding relationship between multiple CORESETs and multiple PDSCHs included in the one PDCCH is established, such as the following configuration form:

[0163]

[0164] PDCCH includes multiple CORESETs, and then establishes a correspondence between multiple CORESETs and multiple PDSCH configuration information. DCI schedules a PDSCH, and according to the high-level configuration information index of the PDSCH corresponding to the CORESET / Search space where the DCI is located, the high-level configuration parameters of the PDSCH are obtained according to the high-level configuration information of the PDSCH corresponding to the configuration information index information. Specifically, for example, PDCCH includes CORESET1 and CORESET2, CORESET1 corresponds to pdsch-Config1, and CORESET2 corresponds to pdsch-Config2. The high-level parameters of the PDSCH scheduled by the DCI transmitted in CORESET1 are obtained according to pdsch-Config1, and the high-level parameters of the PDSCH scheduled by the DCI transmitted in CORESET2 are obtained according to pdsch-Config2.

[0165] Or establish an association between N sets of PDSCH configuration information included in a BWP and multiple scrambling sequence generation parameters of a CORESET, for example, one CORESET corresponds to two scrambling sequence generation parameters C-RNTI{C-RNTI1, C-RNTI2}, establish a corresponding relationship between C-RNTI1 and PDSCH1, and a corresponding relationship between C-RNTI2 and PDSCH2. Then the high-level parameters of the PDSCH scheduled by the DCI successfully decoded by C-RNTI1 are obtained according to pdsch-Config1, and the high-level parameters of the PDSCH scheduled by the DCI successfully decoded by C-RNTI2 are obtained according to pdsch-Config2. The above is that one CORESET corresponds to two C-RNTIs. In this embodiment, one CORESET is associated with only one C-RNTI, but is associated with multiple virtual cell numbers n. ID For example, create two Corresponding to pdsch-Config1, Corresponding to pdsch-Config2, according to The high-level parameters of the successfully decoded DCI scheduled PDSCH are obtained according to pdsch-Config1. The high-level parameters of the successfully decoded DCI-scheduled PDSCH are obtained according to pdsch-Config2.

[0166] The information sequence b(i) after PDCCH channel coding is scrambled with the c(i) sequence, as described in formula (1), where c(i) is the i-th value of a random sequence, and the initialization value of the random sequence is obtained according to formula (2).

[0167]

[0168] c init =(n RNTI 2 16 +n ID )mod2 31 (2)

[0169] where n RNTI In the dedicated control channel, the C-RNTI is used to determine n ID It can be a cell ID.

[0170] The above is to establish a correspondence between multiple downlink control channel resources and multiple PDSCHs. Similarly, a correspondence between multiple downlink control channel resources and multiple PUSCHs can be established, or a correspondence between multiple downlink control channel resources and PUCCHs can be established. One of the control channel resources can be one of the following: a PDCCH corresponding to PDCCH configuration information, a CORESET, a Search space, a Search space corresponding to the aggregation degree, and a parameter corresponding to the scrambling sequence of the DCI.

[0171] In the above implementation, a BWP includes a configuration of multiple PDSCHs. In another configuration information of this embodiment, a BWP still includes a PDSCH, and multiple sets of high-level parameter configurations of the PDSCH belonging to a transmission parameter set are configured. Then, the DCI for scheduling the PDSCH further indicates which set of high-level parameters corresponding to the scheduled PDSCH is configured among the multiple sets of high-level parameter configurations belonging to a transmission parameter set configured in the PDSCH high-level configuration parameters.

[0172] Similarly, a correspondence relationship between multiple control channel resources in a BWP and multiple sets of uplink control channel configurations included in an uplink BWP can be established; and / or a correspondence relationship between multiple control channel resources in a BWP and multiple sets of uplink control channel configurations included in an uplink BWP can be established. The configuration in one set of PUSCH configuration information can correspond to one PUSCH-Config in the configuration in 3Gpp standard version 38.331.V15.0.0, and the configuration in one set of PUCCH configuration information can correspond to one PUCCH-Config in the configuration in 3Gpp standard version 38.331.V15.0.0. Specific embodiment 2:

[0174] In this embodiment, it is necessary to determine the correspondence between P control channel resources and Q sets of configuration information of a transmission parameter set, where the transmission parameter is a transmission parameter of a channel or signal scheduled by the control channel resource. That is, it is necessary to determine the configuration information of the transmission parameter set corresponding to one control channel resource.

[0175] for example Figure 2 There are two TRPs in the transmission, there is no ideal backhaul between the two TRPs, TRP1 and TRP2 independently schedule UEs, thereby increasing spectrum efficiency, TRP1 and TRP2 schedule UEs in the same BWP, although it is believed that the beam isolation between them is relatively good, but the robustness between the reference signal or control channel must be guaranteed. And / or the services of the users served by TRP1 and TRP2 are busy, and the latency requirements are different. It is necessary to consider allowing the configuration of the channels / signals they schedule to be different, so for UE, one transmission parameter under one BWP can correspond to multiple sets of configurations.

[0176] The transmission parameters in the transmission parameter set include at least one of the following transmission parameters: process number set information, uplink control channel resource set information, demodulation reference signal port set, demodulation reference signal information, quasi-common reference signal set information, TCI state pool information, downlink data channel transmission parameter information, uplink data channel transmission parameter, uplink control channel information, PRB Bundling size (precoding resource group size), rate matching information, measurement reference signal information, code block group (Code Block Group, referred to as CBG) information, scrambling sequence generation parameter information, TA information.

[0177] For example, CORESET1 is sent by TRP1, and the PDCCH transmitted in CORESET1 schedules the downlink channel / signal sent by TRP1 to the UE, or the uplink channel / signal sent by the UE to TRP1. CORESET2 is sent by TRP2, and the PDCCH transmitted in CORESET2 schedules the downlink channel / signal sent by TRP2 to the UE, or the uplink channel / signal sent by the UE to TRP2.

[0178] Since TRP1 and TRP2 can schedule PDSCH / CSI-RS / CORESET / PUCCH / PUSCH / SRS / SR in the same BWP, in order to ensure the accuracy of the signal, it is necessary to determine the process number set of the channel scheduled by CORESET1, so that the PDSCH / PUSCH transmitted in TRP1 and TRP2 will not be confused, because TRP1 and TRP2 each transmit channels independently and there is no ideal backhaul between them and they cannot communicate in real time. For example, the process number set configured in CORESET1 is {0,1,2,3}, and the process number of PDSCH / PUSCH indicated in the PDCCH included in CORESET1 is the relative index in the process number set {0,1,2,3}. The process number set configured in CORESET2 is {4,5,6,7}, and the process number of PDSCH / PUSCH indicated in the PDCCH included in CORESET2 is the relative index in the process number set {4,5,6,7}. For example, if the relative index of the process number indicated in the PDCCH is 0, the process number corresponding to PDSCH / PUSCH is 4. If the process number set and the control channel resources are not matched, CORESET1 will also schedule process number 0, and CORESET2 will also schedule process number 0. The terminal will think that they are the same process data and merge them. In fact, they are different data sent by different TRPs and cannot be merged.

[0179] Similarly, an association between CORESET and an uplink control channel resource set can be established, for example, CORESET1 corresponds to PUCCH resource set 1, CORESET2 corresponds to PUCCH resource set 2, and the intersection of resources included in PUCCH resource set 1 and PUCCH resource set 2 is empty, especially the intersection of PUCCH sets corresponding to dynamic signaling is empty, so that CORESET1 and CORESET2 can independently schedule resources in the PUCCH resource set, wherein one PUCCH resource includes time domain resources, frequency domain resources, and spatial domain resources, wherein the spatial domain resources of the downlink reference signal are obtained by configuring the QCL reference signal of the Spatial Rx Parameter of the downlink reference signal through TCI-State, and the spatial domain resources of the uplink reference signal are obtained through the spatial filtering parameter indication information spatialRelationInfo of the reference signal, or the precoding indication information of the uplink reference signal. If any one or more of the time domain resources, frequency domain resources, and spatial domain resources corresponding to two PUCCH resources are different, then the two PUCCH resources are different.

[0180] For example, PUCCH resource 1 corresponds to {time domain resource 1, frequency domain resource 1, spatial domain resource 1}, and PUCCH resource 2 corresponds to {time domain resource 1, frequency domain resource 1, spatial domain resource 2}}, then PUCCH resource 1 and PUCCH resource 2 are considered to be two different resources. This ensures that there is no need for interaction between CORESET1 and CORESET2, and each independently schedules PUCCH resources. Otherwise, they may schedule the same PUCCH resource, so that two uplink control information need to be transmitted simultaneously on the same PUCCH resource, while only one uplink control information can be transmitted on the one PUCCH resource.

[0181] Fig.10 It is a schematic diagram of different PUCCH resource sets corresponding to different TRPs of the present application, such as Fig.10 As shown, due to non-backhaul, if the PUCCH resources scheduled by two TRPs are the same, strong interference between PUCCHs will occur. The above four PUCCHs correspond to the PUCCH resource domain notified by 2 bits in DCI. When the two PUCCH resource sets are different, the interference can be reduced.

[0182] Similarly, a correspondence between CORESET and a demodulation reference signal port set can be established, thereby allowing different TRPs to correspond to different DMRS port sets. The PDCCH transmitted in the CORESET further indicates the relative information of the DMRS corresponding to the scheduled PDSCH / PUSCH in the DMRS port set.

[0183] Similarly, a correspondence between CORESET and demodulation reference signal information can be established, thereby allowing different TRPs to have different DMRS configurations, or ensuring that different TRPs have the same DMRS information. The DMRS information includes at least one of the following information: demodulation reference signal pattern type dmrs-Type, the number of continuous time domain symbol groups occupied by the demodulation reference signal dmrs-AdditionalPosition, the maximum value maxLength of the number of time domain symbols included in a continuous time domain symbol group occupied by the demodulation reference signal, generation parameters for generating a demodulation reference signal sequence, the starting time domain symbol position l0 of the demodulation reference signal, the number of time domain symbols included in a continuous time domain symbol group occupied by the demodulation reference signal, whether the channel transform precoding sent by the one or more third communication nodes to the first communication node is enabled (which can be equivalent to whether SC-OFDM is enabled), demodulation reference signal port information, the frequency domain group where the demodulation reference signal is located, and the power difference between the channels corresponding to the demodulation reference signal and the demodulation reference signal.

[0184] Similarly, an association between CORESET and TCI state pool can be established, for example, CORESET1 corresponds to TCIstate pool1, CORESET2 corresponds to TCI state pool2, one TCI state pool includes one or more TCI states, one TCI state includes one or more QCL reference signal sets, which are used to indicate the QCL reference signal sets corresponding to one or more port groups, and the QCL reference signal set of a port group indicates that the ports in the port group and the reference signals in the QCL reference signal set satisfy the QCL relationship with respect to a type of QCL parameter. The ports in a port group satisfy the QCL relationship, and the reference signals in different port groups do not satisfy the QCL relationship. The ports can be demodulation reference signal ports or measurement reference signal ports. The TCI states corresponding to the QCL reference signal sets of the channels or signals corresponding to the CORESET1 all come from TCI state pool1, wherein the channels or signals corresponding to the CORESET1 include channels or signals scheduled by the PDCCH in the CORESET1, and / or channels or signals scheduled by the high-level signaling, wherein the high-level signaling corresponds to the PDSCH scheduled by the PDCCH in the CORESET1. The TCI states corresponding to the QCL reference signal set of the channel or signal corresponding to CORESET2 are all taken from TCI state pool2.

[0185] Similarly, a correspondence can be established between CORESET and one or more sets of PDSCHs configured by a higher layer, wherein the configuration information of the set of PDSCHs includes configuration information of multiple transmission parameters of the PDSCH. As described above, the PDSCH-config; thus, different TRPs can be allowed to send different transmission parameters of the PDSCH to the UE;

[0186] Similarly, a correspondence between the transmission parameters of the CORESET and the uplink data channel can also be established; thereby allowing the configuration information of the uplink data channel sent to different TRPs to be different;

[0187] Similarly, a correspondence between CORESET and rate matching information can be established, thereby allowing different TRPs to have different rate matching information, where the rate matching information can be the rate matching information configured by RRC signaling, the rate matching information notified by MAC-CE, or the rate matching information set corresponding to the rate matching information notified by DCI.

[0188] Similarly, a correspondence between CORESET and measurement reference signals can be established to allow different TRPs to schedule measurement reference signals from different measurement reference signal resource pools, and to ensure that there is no conflict between measurement reference signals scheduled by two TRPs, especially for uplink measurement reference signals. If two TRPs schedule the same SRS resources, especially when the beam of the SRS resources is determined by the terminal itself, when two TRPs schedule the same SRS resources, the terminal needs to use the same SRS resources but different transmission beams to send to TRP1 and TRP2, which will lead to inaccurate uplink measurements. On the other hand, if the two TRPs schedule CSI-RS occupancy The frequency resources and receiving beam resources are the same, but their transmission beams are actually different. One is the transmission beam of TRP1 and the other is the transmission beam of TRP2. The terminal actually measures the superposition channel of the two transmission beams. However, since there is no real-time interaction between TRP1 and TRP2, TRP does not know that it is the superposition effect of the two. Therefore, it is best that TRP1 and TRP2 each correspond to their own measurement reference signal pools. The two measurement reference signal resources in different measurement reference signal pools are preferably different. The different resources of the two measurement reference signals indicate that at least one of the following resources corresponding to the two measurement reference signal resources is different: time domain resources, frequency domain resources, and spatial domain resources. Or only one TRP in the two TRPs controls the measurement reference signal, but the non-periodic measurement reference signal resource pools corresponding to each CORESET should be different.

[0189] Similarly, an association between CORESET and CBG can be established to allow different TRPs to have different resource allocation granularities; of course, CORESET and time domain resource allocation parameters, and / or frequency domain resource allocation parameters can also be established, such as resource granularity, resource allocation method, and mapping method of physical resources to virtual resources.

[0190] Similarly, an association can be established between CORESET and the generation parameter information of the scrambling sequence, where the scrambling sequence can be a scrambling sequence of a data channel or a scrambling sequence of a control channel, thereby allowing data channels of different TRPs to use different scrambling sequences to reduce interference between the two. The scrambling sequence is to scramble the bit information of the data channel after channel coding and then modulate it;

[0191] Similarly, an association relationship between CORESET and TA information can be established, so that the TA of the uplink channel / signal corresponding to this CORESET adopts the TA value of this CORESET, wherein the channel or signal corresponding to the CORESET indicates that the control signaling for scheduling the channel or signal is included in the control channel included in the control channel resource, or is included in the channel scheduled by the control channel included in the control channel resource. For example, this channel / signal is a channel / signal directly scheduled by the PDCCH included in this CORESET, or is scheduled by high-level signaling of this channel / signal, such as a periodic or semi-periodic channel / signal, and the high-level signaling for scheduling this channel / signal is included in the PDSCH scheduled by the PDCCH included in this CORESET. This allows the TA used for sending to different TRPs to be different. Optionally, since the transmission delays between different TRPs and UEs are different, and the downlink slot boundaries corresponding to TRP1 and TRP2 should be aligned, there should be two downlink timings on the UE side, respectively used to receive the signal sent by TRP1 and the signal sent by TRP2, so that the TA of the uplink channel / signal corresponding to CORESET1 is the time difference between the starting position of time unit 1 corresponding to the above-mentioned uplink channel / signal relative to the starting position of time unit 2, the time unit 2 is a downlink time unit, the time unit indexes corresponding to time unit 1 and time unit 2 are the same, and the starting position of time unit 2 is obtained according to the starting position of the time unit used when the terminal receives CORESET1.

[0192] The above is to establish a corresponding relationship between CORESET and the above transmission parameter set. One CORESET can also correspond to multiple sets of configuration information of one transmission parameter set, and DCI signaling is used to indicate which set the transmission parameters in the transmission parameter set of the channel / signal scheduled by DCI signaling correspond to. For example, one CORESET corresponds to multiple sets of PDSCH high-level coordination information, and then the high-level transmission parameters of the PDSCH scheduled by DCI signaling are based on which set, or the DMRS index indicated in the DCI is relative to which set of DMRS ports in the DMRS port set, or the high-level transmission parameters of the PUCCH scheduled by DCI are which set of PUCCH configuration information corresponding to the CORESET. Figure 3 As shown, one TRP transmits two DCIs, and the other transmits only PDSCH. Assuming that DCI1 and DCI2 are transmitted in the same CORESET, the two sets of configurations of a transmission parameter set corresponding to this CORESET correspond to the channel or signal transmitted by TRP1 and the channel or signal transmitted by TRP2, respectively. The DCI specifically indicates which of the other sets is used by the PDSCH / PUSCH scheduled by the DCI.

[0193] The above establishes a corresponding relationship between a control channel resource and a set of one or more sets of configuration information of a transmission parameter set, wherein one control channel resource is a CORESET. The control channel resource described in this article may also be one of the following: a Search space corresponding to a Search space of an aggregation degree, a set of PDCCH resources configured by a high layer, including only a PDCCH of a DCI, a candidate, and a scrambling sequence generation parameter of a CORESET. For example, n in formula (2) RNTI and / or ID , establish a correspondence between the scrambling sequence generation parameters and one or more sets of configuration information of the above-mentioned transmission parameter set.

[0194] The above is to establish a correspondence between one or more sets of configuration information of a control channel resource and a transmission parameter set. It is also possible to establish a correspondence between one or more sets of configuration information of a control channel resource group and a transmission parameter set. Specific embodiment 3:

[0196] In this embodiment, the terminal uses multiple panels and multiple TRPs to communicate. Fig. 9 This is a schematic diagram of a terminal using multiple panels to send uplink signals to multiple TRPs according to the present application. Figure 1 ,like Fig. 9 As shown, uplink channels / signals sent to different TRPs should use different TA values. For this purpose, at least one of the following solutions can be adopted:

[0197] Solution 1: Establish a TA value corresponding to the channel / signal in the configuration information of the channel / signal, wherein the configuration information may be high-level configuration information or physical layer dynamic control information.

[0198] Solution 2: TA information is configured in the uplink sounding reference signal SRS (Sounding reference signal), and the TA information of PUSCH / PUCCH is obtained according to the SRS information, wherein the spatial filtering parameters, and / or precoding parameters, and / or power parameters of the PUSCH / PUCCH are indicated by the SRS information.

[0199] Solution 3: TA information is configured in the configuration information of a control channel resource, and the TA value of the uplink channel / signal corresponding to the control channel resource is obtained according to the TA information configured in the control channel resource, wherein the uplink channel / signal corresponding to one of the control channel resources indicates that the control signaling for scheduling the uplink channel / signal is included in the control channel included in the control channel resource, and / or the control signaling for scheduling the uplink channel / signal is included in the PDSCH scheduled by the control channel included in the control channel resource.

[0200] In the above scheme, only one TA value of the uplink channel / signal is informed, and a set of TA values ​​is used for downlink synchronization, i.e. Figures 7-8 As shown, the TA values ​​of the signals sent by panel1 and panel2 are both the time advances for panel1 to receive the downlink synchronization signal. More precisely, since the downlink timing of downlink signals to UE without TRP is also different, when a TA value is notified, it should be further notified which downlink signal the TA value is relative to, that is, one TA value corresponds to a combination of (one downlink channel / signal, one uplink channel / signal), wherein the TA is the time difference between the starting position of time unit 1 for sending the uplink channel / signal and the starting position of time unit 2, wherein the time unit 1 is an uplink time unit, the time unit 2 is a downlink time unit, the starting position of time unit 2 is based on the starting position of downlink time unit 3 where the downlink channel / signal corresponding to the TA of the terminal is located, and an integer number of time units are included between the time unit 2 and the time unit 3.

[0201] Specifically, for example, TRP2 does not send a synchronization signal, and the downlink synchronization of panel2 of the terminal UE is determined according to the synchronization signal sent by TRP1. The TA amount when the UE uses panel1 to send an uplink signal to TRP1 is TA1, and the TA amount when the UE uses panel2 to send an uplink signal to TRP2 is TA2. Figure 7-8 As shown, panel1 receives the downlink signal sent by TRP1, where the transmission delay of TRP1 sending and panel1 receiving is t1, and then sends uplink signals to TRP1 and TRP2 respectively. Due to the different uplink transmission delays, the uplink transmission delay of the uplink signal sent by panel1 to TRP1 is t1, and the uplink transmission delay of the uplink signal sent by panel2 to TRP1 is t2.

[0202] Figure 7 According to the present application, when a terminal uses multiple panels to send uplink signals to multiple TRPs, the same downlink timing is used. Figure 1 , Figure 7The time unit boundary of the uplink signal sent by panel1 is obtained according to the downlink time unit boundary obtained by the downlink synchronization signal sent by TRP1 received by panel1; a schematic diagram of UE receiving a synchronization signal according to specific embodiment 4 of the present application.

[0203] Figure 8 According to the present application, when a terminal uses multiple panels to send uplink signals to multiple TRPs, the same downlink timing is used. Figure 2 , Figure 8 The time unit boundary of the uplink signal sent by panel2 is obtained according to the downlink time unit boundary obtained by the downlink synchronization signal sent by TRP1 received by panel1.

[0204] t1 is the downlink transmission delay. When panel1 sends a preamble to TRP1, the uplink transmission delay is also assumed to be t1, TA1 = 2t1;

[0205] When the downlink frame timing of Panel2 is based on the downlink frame timing of Panel1, the accurate value of TA2 should be TA2=t1+t2 (the difference between t2 and t1 is mainly due to the different distances between UE and TRP1 and TRP2, and the different beams of the uplink of Panel1 and Panel2, for example, some are direct paths and some are not direct paths);

[0206] At this time, if the uplink of panel2 is sent at TA1, the arrival time of the uplink signal of panel2 will be earlier or later than the frame timing at panel2. The downlink frame timing of panel2 should be based on the timing of panel2 receiving TRP2, otherwise the first downlink time domain symbol sent by TRP2 will not be the first time domain symbol when it arrives at panel2.

[0207] Or when the downlink frame timing of panel2 is when panel2 receives the downlink synchronization signal sent by TRP1, TA2=t12+t2. At this time, the difference between t12 and t1 is because the beam of the synchronization signal sent by TRP1 received by panel2 is different from the beam of the synchronization signal sent by TRP1 received by panel1.

[0208] Or TRP2 can adjust the TA amount after receiving the uplink signal sent by panel2, but this TA amount is only for the uplink signal of panel2. It is necessary to further determine how to distinguish the uplink signals of panel2 and panel1, such as distinguishing them by different SRS resource groups. For example, panel1 and panel2 correspond to SRS resource group 1 and SRS resource group 2 respectively, or panel1 and panel2 correspond to the uplink signal scheduled by CORESET group 1 and the uplink signal scheduled by CORESET group 2 respectively. In short, the uplink signals need to be grouped in the same service cell, and different groups correspond to different TA amounts.

[0209] In the above schemes, the downlink frame timing of panel2 is based on the synchronization signal sent by TRP1 received by panel1 (transmission delay is t1), or based on the synchronization signal sent by TRP1 received by panel2 (transmission delay is t12). However, the actual downlink timing of panel2 should be based on the synchronization signal sent by TRP2 received by panel2 (transmission delay is t3). When the difference between t3 and t1 / t12 is large, the first time domain symbol sent by TRP2 will not be the first time domain symbol when it arrives at panel2. It is necessary to further consider that the downlink frame timing of Panel2 can allow TRP2 to send a downlink signal and panel2 to make adjustments. However, the definition of the advance amount of TA should be per-panel level, that is, TA1 is the advance amount of the uplink signal of panel1 relative to the downlink frame timing of panel1, and TA2 is the advance amount of the uplink signal of panel2 relative to the downlink frame timing of panel2.

[0210] Optionally, the following manner may also be performed, where the base station notifies the terminal, or is predefined:

[0211] Establish the association between CORESET / SRS / scrambling code / cell ID / Spatial parameter and TA;

[0212] Establishing an association between a downlink reference signal and a TA;

[0213] An association is established between the combination of (downlink reference signal, uplink reference signal) and the TA. Specific embodiment 4:

[0215] Specifically, the data of TRP1 and TRP2 are very independent, so they each have their own process number. However, in order to further reduce the number of bits occupied by the process number in the DCI, different TRPs can correspond to different process number sets, such as TRP1 corresponding to the process number set {1,2,3,4}, and TRP2 corresponding to the process number {5,6,7,8}. Of course, TRP2 can also be configured with {1,2,3,4} in the ideal backhaul scenario. The base station further dynamically indicates the specific process number in the process number set, and obtains the number of bits of the process number in the DCI according to the configured process number set. The process number can be associated with the following information, including: establishing an association between the TCI state group or the TCI state and the process number set. When the TCI of the candidate belongs to group 1, its process number is the first set {1,2,3,4}. When the TCI of the candidate belongs to group 2, the process number is the second set {5,6,7,8}. When the process numbers of two PDSCHs are the same, only one ACK / NACK needs to be fed back. That is, the process number indicated in the DCI is the index information in the first process number set, where the first process number set is configured in the TCI state corresponding to the QCL reference signal set of the demodulation reference signal of the data channel, or the first process number set is configured in the TCI state corresponding to the QCL reference signal set of the demodulation reference signal of the data channel and belongs to the TCI state group.

[0216] Similarly, a TCI state or TCI state group may also be configured with at least one of the following information of a data channel: BWP set information, demodulation reference signal port set information, demodulation reference signal information, quasi-co-reference signal set information, precoding resource granularity PRB bundling size indication information, rate mating indication information, carrier indicator indication information, measurement reference signal information, scrambling sequence generation parameters, control channel port information, time domain resource allocation parameters, frequency domain resource allocation parameters, and non-periodic measurement reference signal information.
