[0237] In order to better understand an uplink communication method disclosed in an embodiment of the present disclosure, a communication system to which the embodiment of the present disclosure is applicable is first described below.

[0238] Figure 1A It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0239] like Figure 1A As shown, the communication system 100 includes a terminal 101 and a network device 102 .

[0240] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited to these.

[0241] In some embodiments, the network device 102 is, for example, a node or device that connects the terminal 101 to a wireless network, and may include an evolved NodeB (eNB), a next generation eNB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (CloudRAN), a base station in other communication systems, an access node in a Wi-Fi system, an A-IoT reader, an A-IoT base station, a terminal, an intermediate node, and at least one of an auxiliary node, but is not limited thereto.

[0242] In some embodiments, the technical solution of the present disclosure may be applicable to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

[0243] In some embodiments, the network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0244] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art 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.

[0245] The following embodiments of the present disclosure can be applied to Figure 1A The communication system 100, or a portion thereof, is shown but is not limited thereto. Figure 1A The various entities shown are examples, and the communication system may include Figure 1A All or part of the subject, and may also include Figure 1A The number and form of other entities are arbitrary, each entity can be physical or virtual, the connection relationship between the entities is illustrative, the entities can be connected or disconnected, the connection can be in any way, it can be direct or indirect, and it can be wired or wireless.

[0246] Embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0247] In some embodiments, in order to improve the coverage of the cell edge and provide better service quality in the service area, multi-point coordinated transmission is an important technical means. It can utilize the cooperation between multiple transmission and reception points (TRP) or multiple antenna panels to transmit / receive from multiple beams at multiple angles, thereby reducing the adverse effects of the blocking effect and enhancing the reliability and throughput of transmission.

[0248] For the uplink, the spatial characteristics of the physical uplink shared channel (PUSCH) for different TRPs may vary greatly. Therefore, it is considered that the type D quasi co-location (Quasi Co-Location Type D, QCL-D) corresponding to PUSCH in different sending directions is different.

[0249] In some embodiments, the terminal may determine the downlink beam based on the downlink transmission configuration indicator (TCI) state or the joint TCI state indicated by the network device; the terminal may determine the uplink beam based on the uplink TCI state or the joint TCI state indicated by the network device. 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 based on the dynamically authorized / configurable PUSCH and all or part of the dedicated physical uplink control channel (PUCCH) resources of a CC.

[0250] In the case of joint beam indication, the TCI field only needs to indicate one joint TCI state, which is used to determine both uplink and downlink transmission beams. However, in 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 separately. In addition, there are three scenarios: it is necessary to indicate both the downlink transmission beam and the uplink transmission beam to the user at the same time, it is only necessary to indicate the downlink transmission beam to the user, or it is only necessary to indicate the uplink transmission beam to the user.

[0251] In some embodiments, the unified TCI state is enhanced for the MTRP scenario and is extended based on the TCI state indication method defined in R17. The uplink and downlink TCI state information corresponding to up to 2 collaborative TRPs can be indicated simultaneously through the TCI state code point in the downlink control information (DCI).

[0252] In some embodiments, in the non-codebook and codebook-based MTRP transmission of R17, the SRS Resource Indicator (SRS Resource Indicator, SRI) field in the DCI indicates the SRS resources in the SRS resource set. Since R17 supports two SRS resource sets, in the non-codebook-based M-TRP PUSCH repeated transmission, the DCI format 0_1 / 0_2 contains two SRI fields associated with the two SRS resource sets. Each SRI field is a TRP indication SRI. The design of the first SRI field is based on the R15 / 16 framework, and all repeated transmissions use the same number of layers.

[0253] Wherein, 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 the SRI combination 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.

[0254] In some embodiments, in codebook-based M-TRP PUSCH repetitive transmission, two Transmitted Precoding Matrix Indicator (TPMI) fields are indicated in DCI format 0_1 / 0_2, wherein the first TPMI field is designed the same as the TPMI field in R15 / 16 (including TPMI index and number of layers), and the second TPMI field only contains the second TPMI index, and the number of layers is the same as the number of layers 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 number of layers indicated by the first TPMI field. The number of bits M2 of the second TPMI field is determined by the maximum number of code points for each rank among all ranks associated with the first TPMI field.

[0255] In some embodiments, based on the Power Headroom Report (PHR), the terminal can report the instantaneous transmit power used to send the uplink channel or signal. The PHR reflects the available power of the terminal, that is, the power headroom, which can be measured and reported to the base station in the control of uplink transmission.

[0256] Optionally, the content reported in the PHR includes at least one of the following:

[0257] The maximum power that can be transmitted in each cell;

[0258] Power headroom after UE sends uplink control channels (such as PUCCH) in each cell;

[0259] The power headroom after the UE sends uplink data channels (such as PUSCH) in each cell;

[0260] The power headroom after the UE sends an uplink sounding channel (such as a Sounding Reference Signal (SRS)) in each cell.

[0261] If the UE has a real physical channel to send, the power headroom after the real transmission of the physical channel, i.e., the real (actual) PHR, is reported. If the UE does not have a real physical channel to send, the power headroom after the reference (or virtual) transmission of the physical channel, i.e., the virtual (virtual) PHR, is reported.

[0262] 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:

[0263] Type 1 PH: PH type1,c (i) = P CMAX,c –P PUSCH,c (i);

[0264] Type 2 PH: PH type2,c (i) = P CMAX,c –P PUSCH,c (i) –P PUCCH,c (i);

[0265] Type 3 PH: PH type3,c (i) = P CMAX,c –P SRS,c (i);

[0266] "i" is a subframe "i", where:

[0267] P PUSCH,c (i) is the transmit power of the uplink data channel (PUSCH) obtained by the UE according to calculation. When the UE has actual signal transmission, this value is determined according to the actual transmitted channel power. When the UE does not have actual signal transmission, this value is determined according to the reference (or virtual) channel power.

[0268] PPUCCH,c (i) is the transmit power of the uplink control channel (PUCCH) obtained by the UE according to calculation. When the UE has actual signal transmission, this value is determined according to the actual transmitted channel power. When the UE does not have actual signal transmission, this value is determined according to the reference (or virtual) channel power.

[0269] P SRS,c (i) is the transmit power of the uplink sounding reference channel (SRS) obtained by the UE according to calculation. When the UE has actual signal transmission, this value is determined according to the actual transmitted channel power. When the UE has no actual signal transmission, this value is determined according to the reference (or virtual) channel power.

[0270] In some embodiments, in the research of multi-TRP (MTRP) transmission, the research direction of R19 will continue to enhance uplink transmission. The main research is on the multi-TRP deployment scenario of downlink single TRP (STRP) / uplink MTRP. In this scenario, by deploying multiple uplink receiving points (UL RxNode), the uplink coverage and throughput can be further improved at a lower network deployment cost, while avoiding complex network planning and downlink interference management coordination issues.

[0271] In some embodiments, in the research of R19, one of the research directions promoted 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). Figure 1B As shown in . Since the macro gNB and micro node UL TRP have different power ratings, the UE can receive downlink (DL) transmissions from the macro gNB, but send UL transmissions to the macro gNB or non-co-located micro node UL TRP to maximize UL throughput. As an option to further reduce energy consumption, the micro node can reduce or even turn off DL transmissions. Unlike low-power radio access nodes (small cells), the micro node (UL TRP) is only used for uplink reception.

[0272] In some embodiments, Figure 1C As shown, considering that the gNB and the uplink receiving node are connected by a feeder link (backhaul), the case of single downlink control information (S-DCI) corresponding to the ideal backhaul is first considered.

[0273] In some embodiments, Figure 1C As shown, the corresponding uplink UL transmission scheme can support the following transmissions:

[0274] STRP transmission based on Dynamic Point Switch (DPS);

[0275] MTRP transmission.

[0276] Among them, optionally, for uplink STRP transmission, uplink STRP transmission can be performed based on macro gNB, or based on a certain UL TRP.

[0277] Optionally, for uplink MTRP transmission, you can select macro gNB and one UL TRP, or you can select two UL TRPs, or you can select macro gNB and two of the UL TRPs, and so on.

[0278] In some embodiments, the specific TCI state indication method to be used depends on the result of beam determination and is configured by the network to the terminal. The current protocol can only support configuring the current beam indication as one of the joint TCI state mode and the independent TCI state mode.

[0279] In some embodiments, Figure 1B or Figure 1C As shown, the cell includes a master gNB and multiple UL TRP receiving points. In order for the terminal to perform downlink STRP / uplink MTRP transmission, the base station needs to perform the 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 collaboration between the master gNB and UL TRP, or between different UL TRPs.

[0280] When the terminal sends an uplink channel / signal, uplink power control is required. Since only the master gNB has a downlink path loss (PL) reference signal (RS), and the UL-only TRP has no downlink signal, the SRS transmit power information is important information that needs to be obtained in the asymmetric MTRP scenario, that is, the terminal needs to report a type 3 PHR, which can facilitate subsequent scheduling.

[0281] In some embodiments, the following two methods can be used for the terminal to estimate the path loss for UL TRP:

[0282] Method 1: Perform downlink path loss estimation based on DL PL RS configuration, and further obtain the path loss estimation value in the UL TRP direction through the configuration value PL_offset of the PL offset value associated with the TCI state corresponding to the UL TRP / UL TRP. Further, the path loss estimation value can be used for uplink channel / signal transmission.

[0283] The path loss estimation value PL_UL in the UL TRP direction is PL_DL-PL_offset, wherein PL_offset can be updated by a Medium Access Control Control Element (MAC CE).

[0284] Method 2: The initial value PL_UL of the UL path loss is calculated by using the configuration value PL_offset of the PL offset value in method 1. By sending an SRS to the UL TRP to update the change PL_offset' relative to PL_UL, the new PL_UL' can be calculated by the following formula:

[0285] PL_UL'=PL_UL+ / -PL_offset'.

[0286] In summary, in order to implement the above-mentioned type 3 PHR reporting, it is necessary to consider defining an SRS resource configuration that is used to assist the network in obtaining the path loss power difference between different TRPs.
