[0097] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a number of terminals 11 and a number of base stations 12.

[0098] Terminal 11 can be a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, terminal 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, terminal 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, terminal 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0099] Base station 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0100] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

[0101] Base station 12 and terminal 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0102] In some embodiments, terminals 11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0103] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0104] Several base stations 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0105] To improve coverage at cell edges and provide a more balanced quality of service within the service area, Coordinated Multiple Point Transmission (CoMP) remains an important technique in New Radio (NR) systems. From a network architecture perspective, deploying a network with a large number of distributed access points combined with centralized baseband processing is more conducive to providing a balanced user experience rate and significantly reduces handover latency and signaling overhead. As frequency bands increase, a relatively denser deployment of access points is also required to ensure network coverage. At higher frequency bands, with the increasing integration of active antenna devices, there is a greater tendency to adopt modular active antenna arrays.

[0106] Based on the mapping relationship between the transmitted signal stream and multiple Transmit Receive Points (TRPs) / antenna panels, multi-point cooperative transmission technology can be divided into coherent and incoherent transmission. In coherent transmission, each data layer is mapped to multiple TRPs / panels through a weighted vector. In incoherent transmission, each data stream is mapped to only a portion of the TRPs / panels. Coherent transmission places higher demands on the synchronization between transmission points and the transmission capacity of the backhaul link, making it more sensitive to many non-ideal factors in real-world deployment conditions. In contrast, incoherent transmission is less affected by these factors and is therefore a preferred solution for multi-point transmission technology.

[0107] Quasi-co-location (QCL) refers to a method where the large-scale parameters of the channel experienced by a symbol at one antenna port can be inferred from the channel experienced by a symbol at another antenna port. These large-scale parameters can include delay spread, average delay, Doppler spread, Doppler offset, average gain, and spatial reception parameters.

[0108] The concept of QCL (Quick Channel Cooperative) was introduced with the emergence of multi-point cooperative transmission technology. Multi-point cooperative transmission involves multiple sites that may correspond to different geographical locations (including TRPs) or sectors with different antenna panel orientations. For example, when a terminal receives data from different sites, the spatial differences between the sites lead to differences in large-scale channel parameters of the receiving link from different sites, such as Doppler frequency offset and delay spread. These large-scale channel parameters directly affect the adjustment and optimization of filter coefficients during channel estimation. Different channel estimation filter parameters should be used to adapt to the corresponding channel propagation characteristics for signals emitted from different sites.

[0109] Therefore, although the differences in spatial location or angle between sites are transparent to the UE and the CoMP operation itself, the impact of these spatial differences on large-scale channel parameters is an important factor that the UE needs to consider when performing channel estimation and reception detection. The so-called QCL (Quasi-Co-location) of two antenna ports under certain large-scale parameters means that these large-scale parameters of the two ports are the same. In other words, as long as certain large-scale parameters of the two ports are consistent, regardless of whether their actual physical locations or the orientation of their corresponding antenna panels differ, the terminal can consider that the two ports originate from the same location (i.e., quasi-co-location).

[0110] For some typical application scenarios, considering the possible QCL relationships between various reference signals, and from the perspective of simplifying signaling, NR classifies several large-scale channel parameters into the following four types to facilitate system configuration / indication according to different scenarios:

[0111] QCL-TypeA: {Doppler frequency shift, Doppler spread, average delay, delay spread}

[0112] - Except for the space receiving parameters, all other large-scale parameters are the same.

[0113] - For frequency bands below 6 GHz, spatial reception parameters may not be required.

[0114] QCL-TypeB: {Doppler frequency shift, Doppler extension}

[0115] - This applies only to the following two scenarios for frequencies below 6 GHz.

[0116] QCL-TypeC:{Doppler frequency shift, average delay}

[0117] QCL-TypeD:{Space Reception Parameters}

[0118] - As mentioned earlier, since this parameter is mainly for frequency bands above 6GHz, it is treated as a separate QCLtype.

[0119] NR Release 15 (Rel-15) specifies that the demodulation reference signal (DMRS) port within each code division multiplexing (CDM) group is QCL.

[0120] A scenario of multi-point collaborative transmission, such as Figure 2 As shown, it includes one terminal and multiple TRPs. Figure 3 As shown, the terminal can transmit uplink PUSCH to multiple base station TRPs. The terminal can use Time-Division Multiplexing (TDM) technology for cooperative transmission. The terminal transmits the same TB of PUSCH to different TRPs of the base station at different times in the time domain. This method has relatively low requirements for terminal capabilities, does not require simultaneous beam transmission, and has a relatively large transmission delay.

[0121] For uplink transmission, the actual spatial characteristics of the PUSCH channels traversed may differ greatly for different TRPs. Therefore, it is assumed that the QCL-D of the PUSCH channels are different for different transmission directions.

[0122] Based on the mapping relationship of the transmitted signal flow to multiple TRP / antenna panels, multi-point cooperative transmission technology can be roughly divided into two types: coherent and incoherent transmission.

[0123] In coherent transmission, each data transmission layer is mapped to multiple TRPs / antenna panels participating in the cooperative transmission via a weighted vector. If the channel parameters of each TRP / antenna panel are the same at a large scale and they use the same frequency source, then coherent transmission is equivalent to stitching multiple subarrays into a higher-dimensional virtual array, thereby achieving higher shaping / precoding / multiplexing gain. However, in practical deployment environments, this approach places higher demands on synchronization between transmission points and backhaul transmission capabilities.

[0124] Incoherent transmission refers to the fact that each data stream is mapped only to the port corresponding to the TRP / antenna panel with consistent large-scale parameters of the channel (i.e., QCL). Different data streams can be mapped to different ports of the QCL. It is not necessary to unify all the cooperative points (multiple TRP / antenna panels for cooperative transmission) as a virtual array and perform joint shaping on each layer.

[0125] Joint transmission can include: Dynamic Point Select (DPS) transmission, Coherent-Joint Transmission (C-JT), and Non-Coherent-Joint Transmission (NC-JT), etc. For example... Figure 4 As shown, in single-point transmission (i.e., DPS transmission), all codewords corresponding to data transmission layers are sent through a single transmission point; for example... Figure 5 As shown, in C-JT, all codewords and layers are transmitted after joint precoding through two transmission points; as Figure 6 As shown, in the NC-JT mode, the two data transmission layers corresponding to codeword 0 are sent from transmission point 1 (TP1), while the two data transmission layers corresponding to codeword 1 are sent from TP2.

[0126] In Time Division Multiplexing (TDM) transmission, the terminal sends the same TB of PUSCH to different TRPs of the base station at different time-domain transmission times, resulting in significant latency and low throughput. Improving transmission reliability and throughput while effectively reducing transmission latency under multiple TRPs is a pressing issue that needs to be addressed.

[0127] like Figure 7 As shown, this exemplary embodiment provides a PUSCH configuration method, which can be executed by a network-side device and / or terminal of a cellular mobile communication system, including:

[0128] Step 701: For the SFN transmission of the uplink PUSCH, different antenna panels of the terminal are configured with different TCIs; the TCIs are associated with beam information, and different TCIs are associated with the same transmission resources, wherein the transmission resources include time domain resources and frequency domain resources, and multiple different antenna panels use SDM to perform the SFN transmission of the PUSCH.

[0129] This embodiment can be applied to, but is not limited to, network-side devices such as core network devices and access network devices, and / or terminals. Terminals here can include handheld terminals and / or non-handheld terminals, etc. No limitation is imposed here.

[0130] The terminal can be a UE capable of simultaneously transmitting data to multiple base station TRPs. The UE can simultaneously transmit uplink data to multiple base station TRPs. Coordinated Multiple Point Transmission / Reception (CoMP) refers to multiple geographically separated TRPs collaboratively sending data to or receiving data from a single terminal. Here, TRPs can include base station antenna panels, etc.

[0131] For example, a terminal can support simultaneous SFN transmission of PUSCH to N TRPs of the base station via N antenna panels, where N is a positive integer greater than or equal to 2. Each antenna panel of the UE can correspond to one TRP of the base station. Different antenna panels of the terminal can use beams in different directions to simultaneously transmit PUSCH SFN.

[0132] SFN transmission can include using multiple antenna panels of a terminal to transmit the same data content to the TRP simultaneously using the same frequency domain resources. For example, SFN transmission can involve a terminal using multiple antenna panels to transmit the same transport block simultaneously using the same frequency domain resources.

[0133] SFN transmission of PUSCH is achieved through multiple antenna panels, meaning the same data content is transmitted via multiple antenna panels. Network-side devices can receive data content through multiple TRPs and obtain the data content through joint decoding and other methods, thus improving the reliability of uplink and downlink transmission.

[0134] In one embodiment, the SFN transmission of the PUSCH includes one of the following:

[0135] SFN's non-coherent transmission NC-JT;

[0136] SFN coherent transmission NC-JT.

[0137] During C-JT of PUSCH, the terminal needs to perform joint shaping of the transmitted data stream through multiple antenna panels, coordinating the coding matrices (relative phase) of different transmission points to ensure that the same data stream can be coherently superimposed at the TRP end. This involves virtualizing the subarrays of multiple antenna panels into a higher-dimensional antenna array to achieve higher shaping gain. Each antenna panel can apply a unified precoding matrix for joint precoding processing to perform C-JT.

[0138] During NC-JT of PUSCH, the terminal does not need to perform joint shaping on multiple antenna panels. Each antenna panel can independently precode its own transmitted data without needing to coordinate relative phases. Each antenna panel can apply its own precoding matrix for independent precoding processing to perform NC-JT.

[0139] Here, a TCI can be configured for each antenna panel of the terminal. The TCI is used to indicate the beam information of the beam used when the corresponding antenna panel performs SFN transmission for push. Here, the beam information is used to indicate at least the direction of the beam. Here, the TCI can be a TCI state.

[0140] The different antenna panels of the terminal are configured with different TCIs. This can be achieved by the network-side device configuring a different TCI for each antenna panel of the terminal. Alternatively, the terminal can determine a different TCI for each antenna panel. Here, the TCI can be sent to the terminal by the network-side device.

[0141] In one embodiment, the TCI includes one of the following:

[0142] Unified TCI;

[0143] Spatial Relationship Information (SRI);

[0144] Detection Reference Signal Resource Indicator (SRI).

[0145] TCI can be Unified TCI. SRI can be used when Unified TCI is not configured.

[0146] A unified TCI can be used when the TRP has beam consistency. A unified TCI indicates uplink and downlink beams through multi-channel and signal sharing, allowing multiple CCs to use a common beam. TRP beam consistency can include: the downlink receive beam and uplink transmit beam of the TRP being reciprocal, meaning the downlink receive beam and uplink transmit beam have beam correspondence. In beam consistency, the direction of the uplink beam is also the direction of the downlink beam.

[0147] The base station can also use Spatial Relation Info (SRI) to indicate TCI to the terminal.

[0148] Base stations can also carry TCI via Sounding Reference Signal Resource Indicators (SRIs). The SRI is used to indicate the uplink analog beam direction corresponding to the SRS resources specifically used for the uplink PUSCH in codebook transmission, and to indicate which SRS resources are used for the uplink PUSCH precoding in non-codebook transmission, i.e., the transmission beam direction at different layers. TCI can be carried using reserved bits in the SRI. Different SRIs can be transmitted for different antenna panels. The TCI in the SRI can be directly associated with the antenna panel that received the SRI.

[0149] In one embodiment, the unified TCI includes one of the following:

[0150] United TCI;

[0151] Independent TCI.

[0152] Different antenna panels correspond to different TCIs, which can be either a combined TCI or an independent TCI.

[0153] Unified TCI can include Joint TCI and Separate TCI. Joint TCI is used to indicate both the uplink transmit beam and the downlink receive beam; Separate TCI is used to indicate either the uplink transmit beam or the downlink receive beam.

[0154] In one embodiment, different TCIs correspond to different transceiver point (TRP) directions of the base station.

[0155] The beam indicated by TCI can be transmitted simultaneously, within the same time slot, using the same time and frequency domain resources. TCI can enable SFN transmission of PUSCH using SDM on different antenna panels by indicating beams in different directions.

[0156] In one embodiment, different TCIs are used to indicate different quasi-co-location type D source reference signals, which are used to determine the TRP direction.

[0157] The Quasi-Co-located Type-D source reference signal (QCL Type-D source RS) may include at least one of the following: Channel State Information Reference Signal (CSI-RS); Synchronous Signal / PBCH Block (SSB); Sounding Reference Signal (SRS).

[0158] The base station and the UE can interact with different quasi-co-location type D source reference signals within different beams to determine which beams are suitable for communication. Each quasi-co-location type D source reference signal is associated with a beam. This association can be a one-to-one correspondence. The directions of the different beams can be different.

[0159] TCI can indicate a beam in one direction using a quasi-co-located type D source reference signal.

[0160] In one embodiment,

[0161] Different unified TCIs use different TCI indicator fields to carry them;

[0162] or,

[0163] Different unified TCIs are carried by a single TCI indicator field.

[0164] A TCI can be carried by multiple independent TCI indication fields. For example, two or more independent TCI indication fields can be used to indicate a TCI, with each TCI indication field carrying one TCI, meaning each TCI indication field indicates a beam direction.

[0165] Multiple TCIs can also be carried by a single TCI indicator field, i.e., a single TCI code point. For example, two TCIs can be carried by a single TCI indicator field, i.e., one TCI indicator field indicates the direction of the first TRP beam and the direction of the second TRP beam.

[0166] In one embodiment, the PUSCH includes at least one of the following:

[0167] PUSCH for Downlink Control Information (DCI) scheduling;

[0168] Type 1 configuration authorization for dispatch-free PUSCH;

[0169] The scheduling-free type is 2CG PUSCH.

[0170] PUSCH can be scheduled by a single DCI. DCI can be delivered via PDCCH resources.

[0171] The Configured Grant (CG) PUSCH is further divided into two types: Type 1 and Type 2. Type 1 CG PUSCH can have all parameters configured via RRC signaling and can be sent periodically once configured. Type 2 CG PUSCH can have some parameters configured via RRC signaling, and then requires Downlink Control Information (DCI) activation / deactivation. The activation of the DCI specifies the remaining parameters, and after activation, it can be used periodically.

[0172] In one embodiment, the TCI is carried in at least one of the following

[0173] Radio Resource Control (RRC) signaling;

[0174] Media Access Control Unit (MAC-CE) signaling;

[0175] DCI signaling.

[0176] Base stations can carry TCI through different signaling methods, which improves the flexibility of TCI indication.

[0177] Thus, on the one hand, by using different TCIs to indicate the beam information of different antenna panels, the beam information of each antenna panel can be configured independently, improving the flexibility of beam configuration. On the other hand, by using SDM for uplink PUSCH SFN transmission, multiple antenna panels can transmit simultaneously, reducing uplink transmission latency under multiple TRPs and improving throughput. Different antenna panels can transmit the same data content, improving transmission reliability. Furthermore, multiple antenna panels using the same transmission resources saves transmission resources and improves transmission resource utilization.

[0178] In one embodiment, different TCIs are associated with the same set of data transmission layers, wherein one set of data transmission layers includes one or more data transmission layers.

[0179] The data transmission layer set associated with a TCI can be the data transmission layer set transmitted by the antenna panel associated with that TCI. Each TCI has the same data transmission layer set, meaning each antenna panel transmits the same data transmission layer. Different antenna panels can transmit the same data content, improving transmission reliability.

[0180] For example, a terminal has two antenna panels. The TCI data transmission layer set corresponding to the two antenna panels includes data transmission layer 1, data transmission layer 2, data transmission layer 3, and data transmission layer 4, for a total of four data transmission layers. The two antennas can each use the same transmission resources to transmit through these four data transmission layers.

[0181] In one embodiment, when transmitting the PUSCH, the maximum number of data transmission layers used by each antenna panel of the terminal is: min{N-p1, N-p2, ..., N-pX};

[0182] Where X is the total number of antenna panels in the terminal; N-px is the maximum number of data transmission layers supported by the x-th antenna panel; and x is a positive integer less than or equal to X.

[0183] Different antenna panels can support different or the same data transmission layers. Since different antenna panels transmit the same data transmission layers, the number of data transmission layers needs to meet the support capability of the antenna panel with the lowest data transmission layer support capability. Therefore, the maximum number of data transmission layers in the TCI-associated data transmission layers can be the number of data transmission layers supported by the antenna panel with the lowest data transmission layer support capability.

[0184] For example, a terminal can report to network-side equipment such as a base station the maximum number of ports included in the maximum source reference signal (SRS) resources supported by different antenna panels of the terminal (the network-side equipment can determine the maximum number of data transmission layers that the antenna panel can support based on the maximum number of ports. For example, the maximum number of ports can be determined as the maximum number of data transmission layers that the antenna panel can support), or the maximum number of data transmission layers that the UE can support. When instructing the terminal on TCI, the network-side equipment can determine the number of data transmission layers in the data transmission layer set based on the maximum number of data transmission layers that each antenna panel can support.

[0185] For example, the maximum number of data transmission layers that the UE's two antenna panels (antenna panel 1 and antenna panel 2) can support are N_p1 and N_p2, respectively. The maximum number of data transmission layers supported during CW mapping is min{N_p1, N_p2}. CW can be mapped to I data transmission layers, where I is less than or equal to min{N_p1, N_p2}.

[0186] like Figure 8 As shown, this exemplary embodiment provides a PUSCH configuration method, which can be executed by a network-side device and / or terminal of a cellular mobile communication system, including:

[0187] Step 801: Different antenna panels of the terminal transmit a single codeword (CW) corresponding to a transport block (TB) of the PUSCH, wherein the single CW is associated with a set of data transmission layers.

[0188] Here, 1 TB can be processed to obtain 1 codeword (CW). Data processing may include code block segmentation, channel coding, rate matching, code block concatenation, etc. One TB of CW can be mapped to M data transmission layers on the same time-frequency resource in the same time slot, where M is a positive integer greater than or equal to 1. M data are transmitted by multiple antenna panels of the terminal.

[0189] For example, such as Figure 9 As shown, taking a terminal with two antenna panels as an example, antenna panel 1 corresponds to a data transmission layer set associated with TCI, including Data Transmission Layer 1, Data Transmission Layer 2, Data Transmission Layer 3, and Data Transmission Layer 4. Antenna panel 2 also corresponds to a data transmission layer set associated with TCI, including two data transmission layers: Data Transmission Layer 1, Data Transmission Layer 2, Data Transmission Layer 3, and Data Transmission Layer 4. One TB of CW can be mapped to four data transmission layers: Data Transmission Layer 1, Data Transmission Layer 2, Data Transmission Layer 3, and Data Transmission Layer 4; that is, data from these four data transmission layers constitutes one CW. During transmission, both antenna panels 1 and 2 transmit Data Transmission Layer 1, Data Transmission Layer 2, Data Transmission Layer 3, and Data Transmission Layer 4. Here, one antenna panel corresponds to one TRP. Each TRP can correspond to a beam direction. The beam directions of each TRP are different.

[0190] In this way, multiple antenna panels using beams from different directions transmit multiple data transmission layers of one TB, achieving SDM (Single Data Delivery). With multiple antenna panels transmitting simultaneously, in the event of transmission failures due to environmental factors, the data transmission layers received from multiple TRPs can be combined and decoded to obtain complete data. This improves transmission reliability.

[0191] In one embodiment, different antenna panels of the terminal use a single redundant version RV for the single codeword CW transmission of the PUSCH.

[0192] like Figure 10 As shown, one TB corresponds to one CW. One TB can be rate-matched based on a redundant version to obtain a CW. The encoded bits are stored in a circular buffer, and rate matching is achieved by sequentially reading from the circular buffer according to the redundant version during each transmission.

[0193] RV can be indicated to the terminal by the network side in the DCI.

[0194] In one embodiment,

[0195] In response to the NC-JT of the PUSCH, each antenna panel and its corresponding precoding matrix undergoes independent precoding processing.

[0196] or,

[0197] In response to the C-JT of the PUSCH, all antenna panels are subjected to joint precoding processing using a precoding matrix.

[0198] For NC-JT with PUSCH, the terminal does not need to perform joint shaping on multiple antenna panels. Each antenna panel can independently precode its own data transmission layer without needing to coordinate relative phases. Each antenna panel can apply its own precoding matrix for independent precoding processing to perform NC-JT.

[0199] For C-JT performing PUSCH, the terminal can perform joint beamforming on the data transmission layers transmitted by each antenna panel through multiple antenna panels. This coordinates the precoding matrices (relative phase) at different transmission points to ensure coherent superposition of the same data transmission layer at the TRP end. Essentially, the subarrays of multiple antenna panels are virtualized into a higher-dimensional antenna array to achieve higher beamforming gain. Each antenna panel can apply a unified precoding matrix for joint precoding processing to perform C-JT.

[0200] In one embodiment, in response to the NC-JT or C-JT performing the PUSCH, the demodulation reference signal DMRS port set associated with different TCIs is the same, wherein one of the DMRS port sets includes one or more DMRS ports.

[0201] For NC-JT or C-JT with SFN transmission, the set of DMRS ports associated with each TCI can be the same. That is, under the same time domain resources and frequency domain resources, each antenna panel has the same DMRS ports for NC-JT or C-JT using SDM.

[0202] The following provides a specific example in conjunction with any of the above embodiments:

[0203] Based on a unified TCI framework, the terminal is configured with N TCI states suitable for simultaneous transmission. Depending on whether MP / MTRP beam consistency is achieved, the terminal can be indicated by either N different joint TCIs or N separate uplink TCIs. Here, N can be 2, meaning there can be two TCIs: TCI1 and TCI2. Each TCI corresponds to the transmit / receive beam of one antenna panel on the terminal and faces a transmit TRP direction. Each TCI contains a different QCL Type-D source RS, and the terminal uses the antenna panel corresponding to the QCL Type-D source RS contained in the TCI for reception.

[0204] If a unified TCI is not configured, it will fall back to the 3GPP release 15 / 16 (R15 / 16) indication scheme and use the SRI combined indication of spatialRelationInfo1 / 2.

[0205] The actual number of data transmission layers supported for each TCI needs to be considered based on the terminal's capabilities. The maximum number of ports or the maximum number of supported data transmission layers may vary depending on the maximum SRS resources supported by different panels reported by the terminal. That is, the maximum number of data transmission layers supported by different antenna panels corresponds to N_p1 and N_p2 for panel1 and panel2, respectively.

[0206] SDM transmission based on a single DCI (S-DCI) can achieve uplink MTRP NC-JT transmission through the following scheme:

[0207] Scheme SDM-4: (e.g.) Figure 9 As shown,

[0208] One TB of data is transmitted over the same time slot and frequency resource through the same data transmission layer set. Multiple TCIs are simultaneously associated with one data transmission layer set. Multiple TCIs are simultaneously associated with one or more DMRS ports. The data transmission layer set includes one or more data transmission layers. For example, TCI1 and TCI2 are simultaneously associated with one or more data transmission layers and with one or more DMRS ports.

[0209] Single-CW transmission is achieved through a single RV, and the encoded bits are transmitted within the same data transmission layer set.

[0210] Each TCI direction is precoded independently, meaning each antenna panel / TRP direction uses an independent precoder.

[0211] The maximum total number of supported transmission layers is 4, but the actual number of layers does not exceed min{N_p1,N_p2}. N_p1 and N_p2 are the maximum number of data transmission layers supported by the two antenna panels of the terminal, respectively.

[0212] Scheme SDM-5: (e.g.) Figure 9 As shown,

[0213] One TB of data is transmitted over the same time slot and frequency resource through the same data transmission layer set. Multiple TCIs are simultaneously associated with one data transmission layer set. Multiple TCIs are simultaneously associated with one or more DMRS ports. The data transmission layer set includes one or more data transmission layers. For example, TCI1 and TCI2 are simultaneously associated with one or more data transmission layers and with one or more DMRS ports.

[0214] Single-CW transmission is achieved through a single RV, and the encoded bits are transmitted within the same data transmission layer set.

[0215] The two TCI directions jointly perform precoding processing, meaning that all antenna panel / TRP transmitted data uses the same precoder at each data transmission layer.

[0216] The maximum total number of supported transmission layers is 4, but the actual number of layers does not exceed min{N_p1,N_p2}. N_p1 and N_p2 are the maximum number of data transmission layers supported by the two antenna panels of the terminal, respectively.
