The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers are controlled by the CU, and the remaining or all of the protocol layers are distributed in the DU and controlled by the CU, but is not limited thereto.

[0245] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0246] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1A or part of the subjects, but are not limited thereto. The subjects shown in FIG. 1A are illustrative, and the communication system can include all or part of the subjects in FIG. 1A, or other subjects other than those in FIG. 1A.

Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0248] In some embodiments, in order to improve the coverage of the cell edge and provide better service quality in the service area, coordinated multi-point transmission is an important technical means. By utilizing the cooperation between multiple transmission and reception points (TRPs) or multiple antenna panels, transmission / reception can be performed from multiple beams at multiple angles, thereby reducing the adverse effects of blocking and enhancing the reliability and throughput of transmission.

[0249] For uplink, the spatial characteristics of the actual channel for different TRP-oriented physical uplink shared channels (PUSCH) can be very different, so it is considered that the different transmission direction PUSCH corresponds to different Quasi Co-Location Type D (QCL-D).

[0250] In some embodiments, the terminal can determine the downlink beam based on the downlink transmission configuration indicator (TCI) state or joint TCI state indicated by the network device, and determine the uplink beam based on the uplink TCI state or joint TCI state indicated by the network device. Wherein, the downlink beam here refers to the beam of the user-specific physical downlink shared channel (PDSCH) and all / part of the physical downlink control channel (PDCCH) in a component carrier (CC), and the uplink beam refers to the uplink transmission spatial filter of the PUSCH based on dynamic authorization / configurable authorization and all or part of the dedicated physical uplink control channel (PUCCH) resources of a CC.

[0251] For the case of joint beam indication, the TCI field only needs to indicate one joint TCI state, which is used to determine the uplink and downlink transmission beams. However, for the case of independent beam indication, the downlink transmission beam and the uplink transmission beam are no longer the same and need to be indicated respectively. Moreover, there are three scenarios: the downlink transmission beam and the uplink transmission beam need to be indicated for a user at the same time, only the downlink transmission beam needs to be indicated for a user, or only the uplink transmission beam needs to be indicated for a user.

[0252] In some embodiments, the united TCI state is enhanced for MTRP scenarios, which is extended based on the R17 defined TCI state indication method. Up to 2 corresponding cooperative TRP uplink and downlink TCI state information can be indicated at the same time through the TCI state code point in the downlink control information (DCI).

[0253] In some embodiments, in the non-codebook and codebook based MTRP transmission of R17, the SRS resource indication (SRI) field in the DCI indicates the SRS resource in the SRS resource set. Since R17 supports two SRS resource sets, in the non-codebook based M-TRP PUSCH repetition transmission, two SRI fields associated with two SRS resource sets are included in the DCI format 0_1 / 0_2, each SRI field indicates SRI for one TRP. The design of the first SRI field is based on the framework of R15 / 16, and the same number of layers is used for all repetition transmissions.

[0254] Among them, for non-codebook based transmission, the first SRI field is used to determine the elements in the second SRI field, and the second SRI field only contains SRI combinations associated with the number of layers indicated by the first SRI field. The number of bits N2 of the second SRI field is determined by the maximum code point number of each rank associated with the first SRI field.

[0255] In some embodiments, in the codebook based M-TRP PUSCH repetition transmission, two transmission precoding matrix indication (TPMI) fields are indicated in the DCI format 0_1 / 0_2, where the first TPMI field and the TPMI field in R15 / 16 are designed the same (including TPMI index and layer number), and the second TPMI field only contains the second TPMI index, and the layer number is the same as the layer number indicated by the first TPMI field. The first TPMI field is used to determine the elements in the second TPMI field, and the second TPMI field only contains the TPMI associated with the layer number indicated by the first TPMI field. The number of bits M2 of the second TPMI field is determined by the maximum code point number of each rank associated with the first TPMI field.

[0256] In some embodiments, based on the power headroom report (PHR), the terminal can report the instantaneous transmit power for transmitting uplink channels or signals. PHR reflects the available power of the terminal, i.e. power headroom, which can be measured and reported to the base station in the control of uplink transmission.

[0257] Optionally, the content reported in the PHR includes at least one of the following:

[0258] the maximum power available for transmission on each cell;

[0259] the power headroom after the UE transmits an uplink control channel (e.g., PUCCH) on each cell;

[0260] the power headroom after the UE transmits an uplink data channel (e.g., PUSCH) on each cell;

[0261] the power headroom after the UE transmits an uplink sounding channel (e.g., SRS) on each cell.

[0262] In the PHR, if the UE has a real physical channel to transmit, the power headroom after the real physical channel is transmitted is reported, i.e., an actual PHR. If the UE has no real physical channel to transmit, the power headroom after the reference (or virtual) physical channel is transmitted is reported, i.e., a virtual PHR.

[0263] In some embodiments, the PHR includes a power headroom (PH) information field, which is used to indicate the level of the power headroom. The types of PH include:

[0264] Type 1 PH: PH type1,c (i) = P CMAX,c (i) - P PUSCH,c (i) - P

[0265] Type 2 PH: PH type2,c (i) = P CMAX,c (i) - P PUSCH,c (i) - P PUCCH,c (i) - P

[0266] Type 3 PH: PH type3,c (i) = P CMAX,c (i) - P SRS,c (i) - P

[0267] “i” is a certain subframe “i”, wherein:

[0268] P PUSCH,c (i): the transmission power of the uplink data channel (PUSCH) obtained by the UE according to the calculation. When the UE has an actual signal to transmit, the value is determined according to the actual transmitted channel power. When the UE has no actual signal to transmit, the value is determined according to the reference (or virtual) channel power.

[0269] PPUCCH,c (i): the transmit power of the uplink control channel (PUCCH) calculated for the UE. When the UE has an actual signal to transmit, the value is determined according to the actual transmitted channel power. When the UE has no actual signal to transmit, the value is determined according to the reference (or virtual) channel power.

[0270] P SRS,c (i): the transmit power of the uplink sounding reference channel (SRS) calculated for the UE. When the UE has an actual signal to transmit, the value is determined according to the actual transmitted channel power. When the UE has no actual signal to transmit, the value is determined according to the reference (or virtual) channel power.

[0271] In some embodiments, in the multi-TRP (MTRP) transmission study, the research direction of R19 will continue to enhance the uplink transmission. The main research is the multi-TRP deployment scenario of downlink single-TRP (STRP) / uplink MTRP. By deploying multiple uplink receiving points (UL Rx Node), the coverage and throughput of the uplink can be further improved at a lower network deployment cost, while avoiding complex network planning and downlink interference management coordination problems.

[0272] In some embodiments, in the R19 study, one of the research directions is to improve the uplink (UL) coverage and throughput by deploying heterogeneous networks to realize asymmetric multi-TRP transmission (downlink single-TRP / uplink multi-TRP), as shown in FIG. 1B. Because the rated power of the macro (macro) gNB and the micro node UL TRP is different, the UE can receive the downlink (DL) transmission from the macro gNB, but transmit the UL to the macro gNB or the non-co-located micro node UL TRP, in order to maximize the UL throughput. As an option to further reduce energy consumption, the micro node can reduce or even turn off the DL transmission, unlike the small cell, which only serves as an uplink receiver.

[0273] In some embodiments, as shown in FIG. 1C, considering the backhaul connection between the gNB and the uplink receiving node, first consider the case of single-downlink control information (S-DCI) corresponding to ideal backhaul.

[0274] In some embodiments, as shown in FIG. 1C, the corresponding uplink UL transmission scheme can support the following transmissions:

[0275] STRP transmission based on dynamic point switch (DPS);

[0276] MTRP transmission.

[0277] For uplink STRP transmission, it can be based on macro gNB or a certain UL TRP.

[0278] For uplink MTRP transmission, it can be based on macro gNB and one UL TRP, or two UL TRPs, or macro gNB and two UL TRPs, etc.

[0279] In some embodiments, the specific TCI state indication method depends on the beam determination result and is configured by the network to the terminal. The current protocol can only support the configuration of the current beam indication as one of the joint TCI state mode and the independent TCI state mode.

[0280] In some embodiments, as shown in FIG. 1B or FIG. 1C, a cell includes one master gNB and multiple UL TRP reception points. For downlink STRP / uplink MTRP transmission, the base station needs to perform uplink / downlink beam management process and configure / indicate the beam information for data / signal transmission to the terminal. The uplink MTRP transmission needs to be completed in cooperation between the master gNB and the UL TRP, or between different UL TRPs.

[0281] When the terminal performs uplink channel / signal transmission, uplink power control is needed. Since only the master gNB has downlink path loss (PL) reference signals (RS), and the UL-only TRP does not have downlink signals, for the asymmetric MTRP scenario, the SRS transmission power information is important information that needs to be obtained, that is, the terminal needs to perform type 3 PHR reporting, which can be beneficial for subsequent scheduling.

[0282] In some embodiments, the following two methods can be used for the terminal to estimate the UL TRP loss:

[0283] Method 1: Downlink loss estimation based on DL PL RS configuration, further, through the configuration of the PL offset value PL_offset corresponding to the TCI state of the UL TRP / UL TRP pair, the UL TRP direction loss estimation value is obtained. Further, the loss estimation value can be used for uplink channel / signal transmission.

[0284] The UL TRP direction loss estimation value PL UL = PL DL - PL offset, where PL offset can be updated by a Medium Access Control Control Element (MAC CE).

[0285] Method 2: Calculate the initial value of UL loss PL UL through the configuration value PL offset of the PL offset value in method 1, update the change amount PL offset' relative to PL UL by sending SRS to the UL TRP, and the new PL UL' can be calculated by the following formula:

[0286] PL UL' = PL UL + / - PL offset'.

[0287] In summary, in order to realize the above type 3 PHR reporting, it is necessary to consider defining SRS resource configuration for assisting the network to obtain the loss power difference between different TRPs.

[0288] The uplink communication method and device provided by the present disclosure will be described in detail below in conjunction with the accompanying drawings.
