[0146] To better understand the uplink communication method disclosed in this embodiment, the communication system to which this embodiment applies is first described below.

[0147] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0148] As shown in Figure 1A, the communication system 100 includes a terminal 101 and a network device 102.

[0149] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0151] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0152] In some embodiments, the network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU. However, this is not the only possibility.

[0153] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0154] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0155] The embodiments disclosed herein can 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0156] In some embodiments, multi-point cooperative transmission is an important technical means to improve coverage at the cell edge and provide better service quality within the service area. It can utilize the cooperation between multiple transmission and reception points (TRPs) or multiple antenna panels to transmit / receive from multiple beams at multiple angles, thereby reducing the adverse effects of obstruction and enhancing transmission reliability and throughput.

[0157] For uplink, the spatial characteristics of the physical uplink shared channel (PUSCH) traversed by different TRPs may vary greatly. Therefore, it is assumed that the type D quasi-co-location (QCL-D) corresponding to the PUSCH in different transmission directions are different.

[0158] 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; the terminal can determine the uplink beam based on the uplink TCI state or joint TCI state indicated by the network device. Here, the downlink beam refers to the beam of all / part of the Physical Downlink Control Channel (PDCCH) in a user-specific Physical Downlink Shared Channel (PDSCH) and a Component Carrier (CC), while the uplink beam refers to the uplink transmit space filter based on the dynamically licensed / configurable licensed PUSCH and all or part of the Dedicated Physical Uplink Control Channel (PUCCH) resources of a CC.

[0159] 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 and uplink transmission beams are no longer the same and need to be indicated separately. Furthermore, there are three scenarios: needing to indicate both downlink and uplink transmission beams to the user simultaneously, only needing to indicate the downlink transmission beam to the user, or only needing to indicate the uplink transmission beam to the user.

[0160] In some embodiments, the united TCI state is enhanced for MTRP scenarios, extending the TCI state indication method defined in R17. Up to two cooperative TRPs' uplink and downlink TCI state information can be simultaneously indicated by the TCI state code points in the Downlink Control Information (DCI).

[0161] In some embodiments, based on a Power Headroom Report (PHR), a terminal can report the instantaneous transmit power used to transmit uplink channels or signals. The PHR reflects the terminal's available power, i.e., power headroom, and can be measured and reported to the base station during uplink transmission control.

[0162] Optionally, the information reported in the PHR includes at least one of the following:

[0163] The maximum power that can be transmitted on each cell;

[0164] The power margin of each UE after transmitting uplink control channels (such as PUCCH) in each cell;

[0165] The power margin of the UE after transmitting uplink data channels (such as PUSCH) in each cell;

[0166] The power margin after the UE transmits the uplink probe channel (such as the Sounding Reference Signal, SRS) in each cell.

[0167] Specifically, if the UE has a real physical channel for transmission, it reports the power margin after the actual transmission of that physical channel, i.e., the actual PHR. If the UE does not have a real physical channel for transmission, it reports the power margin after the reference (or virtual) transmission of that physical channel, i.e., the virtual PHR.

[0168] In some embodiments, the PHR includes a Power Headroom (PH) information field, which indicates the level of power headroom. The types of PH include:

[0169] Type 1 PH: PH type1,c (i)=P CMAX,c –P PUSCH,c (i);

[0170] Type 2 PH: PH type2,c (i)=P CMAX,c –P PUSCH,c (i)–P PUCCH,c (i);

[0171] Type 3 PH: PH type3,c (i)=P CMAX,c –P SRS,c (i);

[0172] “i” represents a subframe “i”, where:

[0173] P PUSCH,c (i): The transmit power of the uplink data channel (PUSCH) obtained by the UE based on calculation. When the UE is actually transmitting a signal, this value is determined based on the actual transmitted channel power. When the UE is not actually transmitting a signal, this value is determined based on the reference (or virtual) channel power.

[0174] P PUCCH,c (i): The transmit power of the uplink control channel (PUCCH) obtained by the UE based on calculations. When the UE is actually transmitting a signal, this value is determined based on the actual transmitted channel power. When the UE is not actually transmitting a signal, this value is determined based on the referenced (or virtual) channel power.

[0175] P SRS,c (i): The transmit power of the UE based on the calculated uplink probe reference channel (SRS). When the UE is actually transmitting a signal, this value is determined based on the actual transmitted channel power. When the UE is not actually transmitting a signal, this value is determined based on the referenced (or virtual) channel power.

[0176] In some embodiments, within the research on multi-TRP (MTRP) transmission, R19 will continue to focus on enhancing uplink transmission. The main research area is multi-TRP deployment scenarios where downlink single-TRP (STRP) / uplink MTRP is used. In this scenario, deploying multiple uplink receiving points (UL RxNodes) can further improve uplink coverage and throughput at a lower network deployment cost, while avoiding complex network planning and downlink interference management and coordination issues.

[0177] In some embodiments, one research direction promoted in R19 was to improve uplink (UL) coverage and throughput by deploying heterogeneous networks to achieve asymmetric multi-TRP transmission (downlink single TRP / uplink multiple TRP), as shown in Figure 1B. 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 transmit UL to either the macro gNB or a non-co-located micro node UL TRP to maximize UL throughput. As an option to further reduce power consumption, the micro node can reduce or even disable DL transmissions; unlike the low-power small cell, the micro node (UL TRP) is used only for uplink reception.

[0178] In some embodiments, as shown in Figure 1C, a backhaul connection can be considered between the gNB and the uplink receiving node. First, the case of single-downlink control information (S-DCI) corresponding to the ideal backhaul can be considered.

[0179] In some embodiments, as shown in FIG1C, the corresponding uplink UL transmission scheme can support the following transmissions:

[0180] STRP transmission based on Dynamic Point Switch (DPS);

[0181] MTRP transmission.

[0182] Optionally, for uplink STRP transmission, uplink STRP transmission can be performed based on a macro gNB or based on a certain UL TRP.

[0183] Alternatively, for uplink MTRP transmission, one can select a macro gNB and one UL TRP, or two UL TRPs, or a macro gNB and two of the UL TRPs, etc.

[0184] In some embodiments, the specific TCI state indication method used depends on the beam determination result and is configured by the network to the terminal. Currently, the protocol can only support configuring the current beam indication as either the joint TCI state mode or the independent TCI state mode.

[0185] In some embodiments, as shown in Figure 1B or Figure 1C, a cell includes a primary gNB and multiple UL TRP receiving points. For a terminal to perform downlink STRP / uplink MTRP transmission, the base station needs to perform uplink / downlink beam management and configure / indicate the beam information used for data / signal transmission to the terminal. Uplink MTRP transmission needs to be completed collaboratively between the primary gNB and the UL TRP, or it can be completed collaboratively between different UL TRPs.

[0186] When a terminal transmits uplink channels / signals, uplink power control is required. Since only the primary gNB has a downlink path loss (PL) reference signal (RS), while the UL-only TRP does not have a downlink signal, how to estimate the path loss for the UL-only TRP is a problem that needs to be solved. For the UL-only TRP, considering the PL estimated relative to the primary gNB, a PL offset parameter is configured for the corresponding PL calculation of the UL-only TRP, thus implementing the corresponding uplink power control. How to specifically implement uplink path loss estimation and the corresponding power control calculation is a crucial problem to be solved for achieving actual transmission in this scenario.

[0187] The uplink communication method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0188] Figure 2A is an interactive schematic diagram of an uplink communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the method involved in this embodiment of the present disclosure is used in a communication system 100, and the method includes:

[0189] In step S2101, network device 102 sends the first information.

[0190] In some embodiments, terminal 101 receives first information sent by network device 102.

[0191] In some embodiments, the first information described above is used to update the path loss offset (PL offset).

[0192] In some embodiments, the first information is used to update the path loss offset value associated with at least one Transmission Configuration Indicator (TCI) state.

[0193] Optionally, in the above-mentioned at least one TCI state, each TCI state is associated with a road loss offset value. There may be cases where multiple TCI states are associated with the same road loss offset value, or there may be cases where each TCI state is associated with a different road loss offset value.

[0194] Optionally, the path loss offset value associated with each TCI state is configured by network device 102.

[0195] In some embodiments, the at least one TCI state is configured by a Radio Resource Control (RRC) message sent by the network device 102.

[0196] In some embodiments, the at least one TCI state can be an uplink TCI state or a joint TCI state.

[0197] Optionally, the mode of the above TCI state is configured by the network device 102 (either an independent TCI state mode or a combined TCI state mode).

[0198] Optionally, when the unified TCI state mode configured by the network device 102 is the joint TCI state mode, the network device 102 configures the joint TCI state to the terminal 101, and the joint TCI state is used for the transmission of uplink and downlink signals or channels.

[0199] Optionally, when the unified TCI state mode configured by the network device 102 is the independent TCI state mode, the network device 102 configures the uplink TCI state and downlink TCI state for the terminal 101, which are used for the transmission of uplink and downlink signals or channels, respectively.

[0200] In some embodiments, the road loss offset value includes at least one of the following: a first road loss offset value; a second road loss offset value.

[0201] The first path loss offset value is used to indicate the offset value of the UL path loss relative to the DL path loss when the UL path loss is based on the DL-based path loss estimate corresponding to the UL TRP.

[0202] The aforementioned second path loss offset value is used to indicate the amount of change in UL path loss corresponding to the UL TRP.

[0203] Optionally, the first path loss offset value mentioned above can be represented by PL_offset1, where the path loss of the uplink corresponding to UL TRP#1 is PL_UL = PL_DL - PL_offset1, and PL_DL is the path loss estimate of the downlink of the main gNB, and PL_UL is the path loss estimate of the uplink of UL TRP#1.

[0204] Optionally, the PL_DL can be a path loss estimate calculated based on the downlink path loss reference signal DL PL RS sent by the network device 102, and the PL_offset1 is associated with the TCI state pointing to the UL TRP#1.

[0205] Optionally, the second path loss offset value mentioned above can be represented by PL_offset2. The path loss of the uplink corresponding to UL TRP#1 can be updated. The updated PL_UL' = PL_UL + PL_offset2, where PL_UL is the path loss estimate of the uplink of UL TRP#1.

[0206] Alternatively, the change in PL_UL' relative to PL_UL (i.e., PL_offset2) can be updated by sending an SRS to UL TRP#1.
