[0101] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 may include a terminal 101 and a network device 102. The network device 102 may include at least one of an access network device and a core network device.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0108] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0110] Alternatively, to improve cell edge coverage and provide more balanced service quality within the service area, multi-point coordination is an important technical approach in NR systems. From a network morphology perspective, deploying a network with a large number of distributed receiving points and centralized baseband processing will be more conducive to providing a balanced user experience rate and significantly reduce the latency and signaling overhead caused by handover.

[0111] Alternatively, as frequency bands increase, relatively denser receiving points can be deployed to ensure network coverage. In high-frequency bands, as active antenna equipment becomes more integrated, modular active antenna arrays are becoming increasingly popular. Each TRP's antenna array can be divided into several relatively independent antenna panels, allowing the overall array configuration and port count to be flexibly adjusted based on deployment scenarios and service requirements. Antenna panels or TRPs can also be connected by optical fiber, enabling more flexible distributed deployment.

[0112] Alternatively, in the millimeter wave band, as the wavelength decreases, the blocking effect caused by obstacles such as people or vehicles becomes more significant. In this case, to ensure link robustness, multiple TRPs or antenna panels can be used to collaborate and transmit / receive from multiple beams at multiple angles to reduce the adverse effects of the blocking effect.

[0113] Optionally, based on the mapping relationship between the transmitted signal streams to multiple TRPs / antenna panels, multi-point coordinated transmission technology can be divided into coherent and incoherent transmission. Optionally, in coherent transmission, each data layer is mapped to multiple TRPs / antenna panels through a weighted vector. Optionally, in incoherent transmission, one data stream is only mapped to TRPs / antenna panels with consistent large-scale parameters of the channel, and different data streams are mapped to TRPs / antenna panels with different large-scale parameters. Among them, large-scale parameters can be Doppler frequency deviation, Doppler spread, average delay, delay spread, etc. Among them, large-scale parameters are often represented by quasi co-location (QCL). Optionally, coherent transmission has higher requirements for synchronization between transmission points and the transmission capacity of the backhaul link. Therefore, it is more sensitive to many non-ideal factors in real deployment conditions.

[0114] Optionally, incoherent transmission is less affected by the above factors and is therefore a key consideration for multi-point transmission technology. The uplink PUSCH transmission is transmitted in the direction of the TRPs of multiple base stations. Optionally, in some versions of the communication protocol, the collaborative transmission under the standardized time division multiplexing (TDM) transmission mode sends different repetitions of the same information on the PUSCH to different TRPs of the base station through different transmission opportunities (TO) in the time domain. This method has relatively low requirements on the terminal capabilities, does not require the ability to support simultaneous beam transmission, and has a large transmission delay. Optionally, for uplink transmission, the PUSCH for different TRPs may actually pass through channels with very different spatial characteristics. Therefore, it is considered that the QCL-D (QCL type D) of the PUSCH in different transmission directions is different.

[0115] Optionally, in some versions of the communication protocol, the uplink transmission is a single TRP transmission, and in other versions of the communication protocol, the M-TRP uplink transmission under S-DCI is enhanced. During the uplink PUSCH transmission process, PUSCH can be transmitted in the TRP direction of multiple base stations.

[0116] Optionally, in the enhancement of some versions of the communication protocol, it is expected to achieve simultaneous collaborative transmission in the TRP direction of multiple base stations through multiple antenna panels (panels) to increase the reliability and throughput of the transmission, and at the same time effectively reduce the transmission delay under multiple TRPs, requiring the terminal to have the ability to send multiple beams simultaneously. The transmission of PUSCH can be based on a single PDCCH, that is, S-DCI-scheduled multi-antenna panel / TRP transmission, as shown in Figure 2a, or it can be based on different PDCCHs, that is, M-DCI-scheduled multi-antenna panel / TRP transmission, as shown in Figure 2b. Among them, Figure 2a is a schematic diagram of a multi-antenna panel / TRP transmission scenario based on S-DCI scheduling, and Figure 2b is a schematic diagram of a multi-antenna panel / TRP transmission scenario based on M-DCI scheduling. Optionally, the terminal multi-panel implementation generally configures multiple physical panels (antenna panels), and the capabilities of different panels may also be different, such as having different numbers of SRS ports, and the maximum number of data transmission layers supported by each panel may not be the same. For example, one panel supports a maximum of 2 layers of transmission, and the other panel supports a maximum of 4 layers of transmission. The network scheduler determines whether the terminal is currently suitable for simultaneous uplink transmission of multiple panels. If the terminal is currently suitable for simultaneous uplink transmission of multiple panels and is scheduled, the network will directly or indirectly indicate the relevant transmission parameters, including terminal-specific beam indication information, the number of data layers used for transmission, the allocation of demodulation reference signal (DMRS) ports used, and precoding indication information.

[0117] Optionally, the uplink multi-antenna panel simultaneously transmits STxMP. The supported transmission schemes for the S-DCI-based PUSCH include:

[0118] One solution is the Space Division Multiplexing (SDM) solution: a transport block (TB) of the PUSCH is sent on the same time-frequency resources to two different TRPs through the corresponding DMRS ports or port combinations allocated on different panels. Different panels / TRPs / transmission occasions (TO) are associated with different transmission configuration indication states (TCI states), that is, associated with different beams.

[0119] Another solution is the spatial multiplexing single frequency network (SFN) solution: a TB of the PUSCH is sent on the same time-frequency resources to two different TRPs through the same DMRS port or port combination allocated on different panels, and different panels / TRPs / TOs are associated with different TCI states.

[0120] Optionally, the multi-antenna precoding of PUSCH supports two different mode configurations, one is codebook-based transmission and the other is non-codebook-based transmission. Generally, the mode to be used is selected based on whether the reciprocity of the uplink and downlink channels is established. Optionally, the terminal can send SRS for the base station to estimate the uplink channel state CSI. Optionally, in the codebook-based PUSCH transmission in NR, the terminal can configure up to one SRS resource set for codebook-based uplink transmission. The SRS resource set can be configured with multiple SRS resources, and the network side will feedback The SRS resource indication (SRI) of the bit is used to select the SRS resource. Optionally, based on the measurement of the uplink CSI, the network determines the precoding matrix and number of transmission layers used by the terminal for actual transmission and notifies the terminal. The data of the terminal in the subsequent uplink transmission can be precoded using the precoding matrix (indicated by the transmit precoding matrix indicator (TPMI)) and the number of transmission layers (indicated by the rank indicator (RI)) specified by the network side. At the same time, the precoded data is mapped to the corresponding antenna port according to the spatial filter corresponding to the SRS resource indicated by the SRI.

[0121] Optionally, different SRSs may be transmitted using different spatial filters. Therefore, the precoded data of the terminal may be filtered using the spatial filter used by the SRS resource indicated by the SRI to support transmission of uplink data from a single layer to full rank.

[0122] Optionally, Table 1 is taken as an example to provide an indication method of SRI for multiple SRS resources.

[0123] Optionally, Table 2 takes 4 antenna ports as an example and provides the signaling indication methods of TPMI and RI for single-layer transmission, respectively, for different UE capabilities. UE capabilities include full correlation, partial correlation, and non-correlation, which characterize the correlation capabilities of antenna ports.

[0124] Optionally, Table 3 provides corresponding codewords for single-layer transmission of 4 antenna ports.

[0125] Optionally, the table corresponding to the SRI indication specified in the system protocol is shown below.

[0126] Table 1

[0127] (Table 7.3.1.1.2-32: if ul-FullPowerTransmission is not configured, or ul-FullPowerTransmission=fullpowerMode1, or ul-FullPowerTransmission=fullpowerMode2, or ul-FullPowerTransmission=fullpower and N SRS =2)

[0131] (Table 7.3.1.1.2-32B:SRI indication for codebook based PUSCH transmission, if ul-FullPowerTransmission=fullpowerMode2 and N SRS =4)

[0132] Optionally, not all terminals can calibrate each antenna port to enable coherent transmission. The codebook design for uplink transmission can take into account the coherent transmission capability of the terminal's antenna. Optionally, the NR system defines three types of terminal antenna coherent transmission capabilities: Full Coherent: All antennas of the terminal can transmit coherently; Partial Coherent: Antennas within the same coherent transmission pair of the terminal can transmit coherently, but coherent transmission pairs cannot transmit coherently. Non-coherent: The terminal has no antenna that can transmit coherently. Optionally, the NR system allows the base station to configure up to two SRS resources for the terminal for channel detection based on codebook uplink transmission. The two SRS resources contain the same number of SRS antenna ports and have the same time domain type, that is, both SRS resources are periodic SRS, semi-persistent SRS, or non-periodic SRS. Optionally, the NR system does not support the base station indicating multiple SRS resources to the terminal for codebook-based uplink transmission. When the base station configures two SRS resources for the terminal for codebook-based uplink transmission, the base station indicates to the terminal one SRS resource corresponding to the TPMI / TRI (Transmission Precoding Matrix Indicator / Transmission Rank Indicator) through SRI. Optionally, the following tables 4 to 12 show the tables corresponding to the TPMI indication specified by the system protocol.

[0168] Optionally, for non-codebook based uplink transmission, the terminal sends a capability of a maximum number of SRS resources that can be transmitted simultaneously to the base station.

[0169] Optionally, assuming that the base station indicates SRI to the terminal in time slot n, the corresponding SRS resource transmission is the most recent SRS resource transmission before time slot n. Optionally, the terminal determines the limit of the precoding indication based on the maximum number of transmission layers maxRank in the high-level parameter PUSCH-Config, and the number of SRS resources indicated by SRI is not greater than maxRank. Optionally, the base station can configure an associated CSI-RS resource for channel measurement for the SRS resource set used for non-codebook uplink transmission. The terminal obtains the precoding of the SRS transmission of the SRS resource set used for non-codebook uplink transmission based on the associated CSI-RS resource. Optionally, for non-codebook uplink transmission, in actual systems, the CSI-RS configured for downlink can generally be measured, and the terminal uses uplink and downlink reciprocity to obtain uplink channel information by measuring the downlink signal. The processes included mainly include: 1. The network configures an associated downlink CSI-RS for non-codebook transmission for terminal downlink channel detection. 2. The terminal selects the precoding matrix through calculation of the downlink channel, and sends SRS in each precoding beam direction on the configured SRS resource set. 3. The base station performs uplink channel detection on the SRS, and the network schedules resources for the UE at the same time, notifies the UE through downlink signaling, and selects the beam in the precoding matrix through the SRI indication. 4. The terminal uses the modified precoding matrix to determine the actual precoding and the allowed number of layers to send PUSCH; the terminal determines the limit of the precoding indication based on the high-level parameter maxRank, and the number of SRS resources indicated by SRI is not greater than maxRank. In order to enable the network to modify the precoding matrix actually used by the terminal, for non-codebook based transmission, the network can configure an SRS resource set for the terminal.

[0170] Optionally, for a non-codebook transmission scheme, the base station may configure one SRS resource set for the terminal, comprising one to four SRS resources, each of which comprises one SRS port. When the base station configures multiple SRS resources for the terminal for non-codebook uplink transmission, the multiple SRS resources have the same time domain type, i.e., all SRS resources are periodic SRS, semi-persistent SRS, or aperiodic SRS.

[0171] Optionally, the base station can indicate to the terminal through SRI that one or more SRS resources are used for PUSCH precoding determination. The number of SRS resources corresponding to SRI is the number of streams transmitted by PUSCH. When the base station configures only one SRS resource for the terminal for non-codebook uplink transmission, the DCI used for uplink authorization does not contain the SRI field. Optionally, the specific method of indicating the SRI indication field for non-codebook transmission specified in the system protocol can be seen in Tables 19 to 22 below: Optionally, the following L maxThat is, the number of transmission layers configured by the base station is limited. The terminal determines the corresponding table of SRI and the number of bits in the SRI indication field according to the parameter configuration.

[0173] (Table 7.3.1.1.2-28:SRI indication for non-codebook based PUSCH transmission, L max =1)

[0178] Table 22

[0179] (Table 7.3.1.1.2-31:SRI indication for non-codebook based PUSCH transmission, L max =4)

[0180] Optionally, in non-codebook and codebook-based M-TRP transmissions, the SRI field in the DCI indicates the SRS resources in the SRS resource set. Since two SRS resource sets are supported, in non-codebook-based M-TRP PUSCH repeated transmissions, the DCI format 0_1 / 0_2 contains two SRI fields associated with the two SRS resource sets. Each SRI field indicates SRI for one TRP, and all repeated transmissions use the same number of layers. Optionally, for non-codebook-based transmissions, 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 number of code points for each rank among all ranks associated with the first SRI field. Optionally, in the codebook-based M-TRP PUSCH repeated transmission, two TPMI domains are indicated in the DCI format 0_1 / 0_2, wherein the first TPMI domain is designed the same as the TPMI domain in some versions of the communication protocol (including TPMI and the number of transmission layers), and the second TPMI domain only contains the second TPMI, and the number of transmission layers is the same as the number of transmission layers indicated by the first TPMI domain. Optionally, the first TPMI domain is used to determine the elements in the second TPMI domain, and the second TPMI domain only contains the TPMI associated with the number of transmission layers indicated by the first TPMI domain. The number of bits M2 of the second TPMI domain is determined by the maximum number of code points for each rank of all ranks associated with the first TPMI domain. The SRS resource set indicator indication domain is used to dynamically indicate STRP and MTRP transmission scheduling. In the case of a single TRP, the first SRI domain / TPMI domain can be associated with any SRS resource. Specifically, the SRS resource set indicator indication domain is used for dynamic switching indication between STRP and MTRP through different code points. As shown in Table 23 below.

[0181] Table 23

[0182] Optionally, the uplink multi-antenna panel simultaneously transmits the PUSCH transmission of STxMP. Different SRS resource sets can be configured for PUSCH transmission of different TRP / panel / TCI states, with a total of 2 SRS resource sets configured.

[0183] Optionally, for the SDM mode of STxMP transmission, the terminal implementation can consider one of the following two implementations:

[0184] Mode 1: Shared baseband digital ports mode (shared digital ports).

[0185] Optionally, the shared baseband digital port mode indicates that the terminal baseband digital port is shared among various digital ports of various antenna panels.

[0186] Optionally, the corresponding baseband digital port is shared among the panels.

[0187] Optionally, the number of baseband transmission links of the UE is less than or equal to the total number of antenna ports of the cooperative panel, and the baseband transmission link and both panels can be connected and transmitted on different panels according to each scheduling dynamic.

[0188] Optionally, the number of baseband transmission links corresponds to the total number of PUSCH ports. For the implementation of 4T+4T, the terminal can implement up to 4 transmission links to support the transmission requirements under STRP and MTRP. For the terminal, it can save costs and efficiently implement the transmission of STxMP. As shown in Figures 2c to 2f below. Figure 2c is a schematic diagram of the TRP transmission scenario of a single transmission receiving point on a single antenna panel in an embodiment of the present disclosure, Figure 2d is a schematic diagram of the SDM or SFN transmission scenario in an embodiment of the present disclosure, Figure 2e is a schematic diagram of the TRP transmission scenario of a single transmission receiving point on a multi-antenna panel in an embodiment of the present disclosure, and Figure 2f is a schematic diagram of the TRP transmission scenario of multiple transmission receiving points on multiple antenna panels in an embodiment of the present disclosure.

[0189] Mode 2: Separate digital ports mode.

[0190] Optionally, the independent digital port mode means that the baseband digital port is not shared between various panels, that is, each baseband transmit link (Tx Chain) of the UE has a fixed physical connection with different panels.

[0191] In the uplink enhancement of some versions of the communication protocol, the goal is to support higher uplink throughput and more reliable transmission performance through multi-panel / multi-TRP uplink simultaneous transmission enhancement.

[0192] Optionally, in the standardization of uplink multi-antenna panel simultaneous transmission STxMP, a PUSCH S-DCI-based SDM / SFN transmission scheme is supported.

[0193] Optionally, the implementation of STRP can be from a single antenna panel (single-panel) to a single transmission receiving point (S-TRP), or from a single antenna panel (multi-panel) to a single transmission receiving point (S-TRP). Different implementations correspond to the same SRS resource configuration, but the actual number of panels used is different. For the terminal, the latter implementation uses multiple antenna panels (panels) regardless of STRP or MTRP.
