[0049] The UL transmission power P(q PL ,i,j,C,n) is
number
[0050] In one embodiment, a first set maximum output power corresponds to a first TCI state and a second set maximum output power corresponds to a second TCI state. CMAX,C1 corresponds to TCI state ID 1, and P CMAX,C2 corresponds to TCI state ID 2.
[0051] In one embodiment, the first UL transmit power corresponds to a first indicated TCI state and the second UL transmit power corresponds to a second indicated TCI state. 1 corresponds to TCI state ID 1, and P 2 corresponds to TCI state ID 2.
[0052] FIG. 2A is a schematic diagram showing a physical uplink shared channel (PUSCH) in a multiple downlink control information (M-DCI) based on a multiple transmission / reception point (TRP) operation. Referring to FIG. 2A, in a multiple TRP operation, each DCI from a corresponding TRP may grant a corresponding PUSCH, and each DCI is associated with a value of CORSETPoolIndex. For example, UL grant DCI#1 from TRP#1 via beam#1 in panel#1 is associated with CORSETPoolIndex0, and UL grant DCI#2 from TRP#2 via beam#2 in panel#2 is associated with CORSETPoolIndex1.
[0053] Figure 2B is a schematic diagram showing resource collision. Referring to Figures 2A and 2B, the T / F resources for two TRPs are indicated by two DCIs, respectively. The time / frequency (T / F) resources of UL transmissions sent to TRP#1 and TRP#2 may be partially overlapping or non-overlapping.
[0054] Figure 2C is a schematic diagram showing PUSCH in single downlink control information (S-DCI) based on multi-TRP operation. Referring to Figure 2C, single DCI may allow PUSCH to be transmitted simultaneously to multiple TRPs from different UE panels. Taking Figure 2C as an example, UL grant DCI#1 instructs PUSCH transmission on beam#1 in panel#1 to TRP#1, and PUSCH transmission on beam#2 in panel#2 to TRP#2.
[0055] Figure 2D is a schematic diagram showing resource collision. With reference to Figures 2C and 2D, the T / F resources of UL transmissions sent to TRP#1 and TRP#2 may completely overlap as shown in Figure 2D, but the spatial resources are differentiated by different beams.
[0056] 3A is a schematic diagram showing a spatial division multiplexing (SDM) scheme. Referring to FIG. 3A, in the SDM scheme, different layers / DMRS ports of one PUSCH can be precoded separately and transmitted simultaneously from different UEs. Thus, the spatial multiplexing gain is enhanced.
[0057] For spatial diversity gain, the PUSCH may be demodulated separately on each TRP or jointly on both TRPs. For example, FIG. 3B is a schematic diagram showing a single frequency network (SFN) scheme. Referring to FIG. 3B, in a transmission scheme based on SFN, all of the same layers / DMRS ports of one PUSCH are transmitted simultaneously from two different UE panels.
[0058] STxMP PUSCH and PUSCH transmission based on multi-DCI may support full / partial / non-overlapping in frequency domain and full / partial overlap in time domain, e.g., as shown in Figures 2B and 2D. There are several scenarios that may be encountered: Handle PUSCH power adjustment when two PUSCHs fully / partially overlap in time domain. No symbol-level power adjustment within PUSCH transmission opportunity in case of full / partial overlap in time domain.
[0059] For example, for STxMP, the first UL transmission (e.g., first PUSCH) and / or the second UL transmission (e.g., second PUSCH) in a system based on multiple DCI may be as shown below: A first UL transmission (eg, a first PUSCH) and a second UL transmission (eg, a second PUSCH) may be transmitted simultaneously in the same CC / BWP. Two independent PUSCHs associated with different TRPs may be transmitted simultaneously in the same active BWP. The total number of layers of these two PUSCHs may be up to four. The number of layers for each of these two PUSCHs may be up to two. A UE may be configured with two SRS resource sets for codebook-based or non-codebook-based UL transmissions. Here, each SRS resource set may be associated with a corsetPoolIndex value, A first SRS resource set may be associated with a corsetPoolIndex value of 0 and the other SRS resource set may be associated with a corsetPoolIndex value of 1; The PUSCH may be associated with an SRS resource set of the same corsetPoolIndex value, The first SRS resource set may be, for example, the set with a relatively low set ID, The second SRS resource set may be, for example, a set having a relatively low set ID, Here, the UE may be configured / instructed with the maximum number of SRS resources in each set for codebook-based or non-codebook-based UL transmission. Here, the UE may be configured / instructed with the maximum number of SRS ports in each set for codebook-based or non-codebook-based UL transmissions. The first UL transmission (e.g., first PUSCH) and / or the second UL transmission (e.g., second PUSCH) may be a configured grant or a dynamic grant indicated by DCI.
[0060] Regarding the SRI / TPMI fields in the DCI: For DG-PUSCH, the indicated SRI / TPMI field corresponds to an SRS resource set associated with the same corsetPoolIndex value of CORSET that can receive scheduling DCI format 0_1 or 0_2. For Type 2 CG-PUSCH, the indicated SRI / TPMI field corresponds to the SRS resource set associated with the same corsetPoolIndex value of the CORSET that can receive the activation DCI. For Type-1 CG-PUSCH, one SRS_resource_set_index value may be configured in RRC in ConfiguredGrantConfig, and srs-ResourceIndicator / precodingAndNumberOfLayers corresponds to the SRS resource set.
[0061] The UE may disable (eg, unexpectedly) the first UL transmission being a PUSCH (or PUCCH) and the second UL transmission being a PUCCH (or PUSCH).
[0062] 4A is a schematic diagram showing a multi-panel transmission scheme in multi-TRP operation. Referring to FIG. 4A, the UE may, for example, P CMAX,C : e.g. total maximum output power per cell, P CMAX,C1 : the maximum output power associated with, for example, Panel #1, P CMAX,C2 For example, the maximum output power associated with panel #2 The maximum output power for each cell may be set at least by one value.
[0063] FIG. 4B is a schematic diagram showing panel-specific power allocation. Referring to FIG. 4B, the UE may, for example, Power split mode: P CMAX,C1 +P CMAX,C2 =P CMAX,C , e.g., α P CMAX,C +(1-α)·P CMAX,C =P CMAX,C , Partial power sharing mode:P CMAX,C1 +P CMAX,C2 >P CMAX,C , e.g., 0.6 P CMAX,C +0.6·P CMAX,C >P CMAX,C At least one panel-specific power allocation may be set, such as:
[0064] FIG. 5A is a schematic diagram illustrating a multi-panel transmission scheme with high priority UL transmission.CMAX,Cn (e.g., n=1 or 2) is set for each cell. CMAX,C If the configuration is the same as Reliability loss: e.g. limited SINR of high priority UL transmission to TRP1, Efficiency loss: e.g. MCS levels with limited allocated resource blocks and uneven UL transmit loading.
[0065] 5B is a schematic diagram showing panel-specific power allocation. Referring to FIG. 5B, in the power division and partial power sharing schemes, the remaining power of the transmission power may not be shared with Panel #1.
[0066] How to support flexible allocation of UL transmissions for STxMP may be required in the following scenarios: For example, M-DCI (e.g., ideal or non-ideal backhaul), For example, TRP on / off for NW energy saving.
[0067] Figure 6 is a schematic diagram illustrating a wireless communication network architecture according to one exemplary embodiment of the present invention. Referring to Figure 6, a radio access network architecture (e.g., a Long Term Evolution (LTE) system, a LTE-Advanced (LTE-A) system, a LTE-Advanced Pro system, or a 5G NR radio access network (RAN)) typically includes at least one base station (BS) NW, at least one UE, such as UE1 and UE2, and one or more optional network elements that provide a connection to the network. UE1 and UE2 communicate with a network (e.g., a core network (CN), an Evolved Packet Core (EPC) network, an Evolved Universal Terrestrial Radio Access Network (E-UTRAN), a 5G Core (5GC), or the Internet) via a RAN established by one or more base stations.
[0068] It should be noted that in the present invention, UE1 or UE2 may include, but is not limited to, a mobile station, a mobile terminal or device, or a user communication wireless terminal. For example, UE1 or UE2 may be a portable wireless device, including, but not limited to, a mobile phone, a tablet, a wearable device, a sensor, a vehicle, and a Personal Digital Assistant (PDA) with wireless communication capabilities. UE1 or UE2 is configured to transmit and receive signals through an air interface with one or more cells in a wireless access network.
[0069] The base station NW is configured to provide communication services based on at least one of the following radio access technologies (RATs): Worldwide Interoperability for Microwave Access (WiMAX), Global System for Mobile communications (GSM, also called 2G), GSM Enhanced Data rates for GSM Evolution (EDGE) Radio Access Network (GERAN), General Packet Radio Service (GPRS), Universal Mobile Telecommunication System (UMTS, also called 3G) based on wideband-code division multiple access (W-CDMA), high-speed packet access (HSPA), LTE, LTE-A, eLTE (evolved LTE, e.g. LTE connecting to 5GC), NR (also called 5G), and / or LTE-Pro. However, the scope of the present invention should not be limited to the above protocols.
[0070] The base station NW may include, but is not limited to, a node B (NB) in UMTS, an evolved node B (eNB) in LTE or LTE-A, a radio network controller (RNC) in UMTS, a base station controller (BSC) in a GSM / GSM Enhanced Data rates for GSM Evolution (EDGE) radio access network (GERAN), a next-generation eNB (ng-eNB) in an evolved universal terrestrial radio access (E-UTRA) BS connecting to 5GC, a next-generation Node B (gNB) in a 5G access network, and other devices capable of wireless communication control and radio resource management within a cell. The BS NW may connect to a network to serve one or more UEs via a radio interface.
[0071] A base station (BS) NW (also called a network device) may be operable to provide wireless coverage to a particular geographical area using multiple cells included in the RAN. The BS NW may support the operation of cells. Each cell may be operable to serve at least one UE within its wireless coverage. Specifically, each cell (also called a serving cell) may serve one or more UEs in its wireless coverage (e.g., each cell may schedule downlink (DL) and optionally uplink (UL) resources for DL and optionally UL packet transmission to at least one UE within its wireless coverage). The BS NW may communicate with one or more UEs in a wireless communication system via multiple cells. Note that in the UL, the UE is a transmitter that performs UL transmission, and the network (node) is a receiver that performs UL reception. In the DL, the UE is a receiver that performs DL reception, and the network (node) is a transmitter that performs DL transmission.
[0072] The base station NW may include a network node NN and one or more TRPs, such as TRP#1 and TRP#2.
[0073] The network node NN is, but is not limited to, a node B (NB) in LTE, an evolved node B (eNB) in LTE-A, a radio network controller (RNC) in UMTS, a base station controller (BSC) in GSM / GERAN, a new radio evolved node B (NR eNB) in NR, a next generation eNB (gNB) in NR, and other devices capable of wireless communication control and radio resource management in one or more cells.
[0074] A TRP (e.g., TRP#1 or TRP#2), which may also be considered as a remote radio head (RRH), may be a transceiver in a protocol of a 5G NR wireless communication system and / or a protocol of a 4G wireless communication system. The TRP may be communicatively connected to a network node NN. The network node NN may be connected to serve one or more UEs via one or more TRPs in the wireless communication system. For example, but not limited to, TRP#1 and TRP#2 serve UE1, and TRP#2 serves UE2.
[0075] As described above, the NR frame structure supports flexible configuration to adapt to various next-generation (e.g., 5G) communication requirements such as Enhanced Mobile Broadband (eMBB), Massive Machine Type Communication (mMTC), and Ultra-Reliable and Low-Latency Communication (URLLC) while meeting the requirements of high reliability, high data rate, and low latency. Orthogonal Frequency Division Multiplexing (OFDM) technology agreed upon in 3GPP may serve as the baseline for the NR waveform. Scalable OFDM numerology such as adaptive subcarrier spacing, channel bandwidth, and cyclic prefix (CP) may also be used. In addition, two coding schemes are considered for NR: (1) low-density parity check (LDPC) codes and (2) polar codes. The adaptation of the coding scheme may be configured based on the channel condition and / or the service application.
[0076] It should be noted that the terms "system" and "network" used in the present invention are often used interchangeably. The term "and / or" in the present invention is merely an association relationship describing related objects, which means that there can be three kinds of relationships, for example, A and / or B means three situations: A exists alone, A and B exist simultaneously, or B exists alone. In addition, the character " / " in the present invention usually indicates that the related objects are in an "or" relationship.
[0077] In order to facilitate understanding of the technical solutions of the embodiments of the present invention, the technical concepts related to the embodiments of the present invention are described below.
[0078] FIG. 7 is a flow diagram illustrating a method for UL transmission in multiple panels according to one exemplary embodiment of the present invention. Referring to FIG. 7, the method is adapted to a UE. The UE receives a Sounding Reference Signal (SRS) configuration (step S710). Specifically, the SRS configuration includes a first SRS resource set, a second SRS resource set, and a usage status of the first SRS resource set and the second SRS resource set, and the usage status of the first SRS resource set and the second SRS resource set is one of a codebook manner and a non-codebook manner. The UE may provide two SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2. For example, for STxMP, a first UL transmission (e.g., a first PUSCH) and / or a second UL transmission (e.g., a second PUSCH) may be required, e.g., in a multi-DCI based system, and the UE may be configured with two SRS resource sets for codebook-based or non-codebook-based UL transmission.
[0079] Each SRS resource set may be associated with a coresetPoolIndex value. For example, a first SRS resource set may be associated with a coresetPoolIndex value of 0, and the other SRS resource set may be associated with a coresetPoolIndex value of 1. The PUSCH may be associated with an SRS resource set with the same value as coresetPoolIndex. The first SRS resource set may be, for example, a set with a relatively low set ID, and the second SRS resource set may be, for example, a set with a relatively non-low set ID. The resource set usage indicates that the resource set is used for one of codebook-based UL transmission and non-codebook-based UL transmission. In one embodiment, the SRS configuration (e.g., for a serving cell) is received from the serving cell. For example, the serving cell is TRP#1 and / or TRP#2.
[0080] The UE receives a configuration for UL (step S720). Specifically, the configuration for UL indicates a multi-panel transmission scheme. In one embodiment, the multi-panel transmission scheme is indicated as / from one of the SFN (single frequency network) scheme shown in Figure 3B and the SDM (spatial division multiplexing) scheme shown in Figure 3A.
[0081] The UE receives downlink control information (DCI) (step S730). Specifically, the DCI indicates that a first transmission configuration indicator (TCI) state is associated with a first SRS resource set and a second TCI state is associated with a second SRS resource set for a multi-panel transmission mode. For example, a UL transmission associated with a first SRS resource set is indicated by an SRS resource set field in the DCI, and a UL transmission associated with a second SRS resource set is indicated by an SRS resource set field in the same or another DCI. In one embodiment, the first TCI state is configured as a joint TCI state for downlink (DL) or UL, or configured as a TCI state for UL, and the second TCI state is configured as a joint TCI state for DL or UL, or configured as a TCI state for UL. In one embodiment, the spatial relationship information for the UL transmission is associated with a first applied joint / DL / UL TCI state and / or the spatial relationship information for the UL transmission is associated with a second applied joint / DL / UL TCI state.
[0082] The UE transmits one or more UL transmissions based on the DCI (step S740). Specifically, the one or more UL transmissions include one or more power headroom reports (PHRs). The power headroom indicates how much transmit power is left in the UE in addition to the power used by the current transmission. The PHR may be a type of MAC CE that reports the headroom between the current UE Tx power (estimated power) and the nominal power. In one embodiment, the UE may determine a first UL transmit power and a second UL transmit power of the at least one UL transmission.

CMAX,C1 +P CMAX,C2 =P CMAX,C , and α A is a fixed value, e.g. 0.5, Configurable power division for simultaneous UL transmissions (e.g. between panels): For example, as shown in FIG. CMAX,C1 +P CMAX,C2 =P CMAX,C , and α B configurable by the gNB, e.g., via RRC, MAC CE, and / or DCI; Partial power sharing for simultaneous UL transmissions (e.g. between panels): For example, as shown in FIG. CMAX,C1 +P CMAX,C2 >P CMAX,C , and α C1 and α C2 can be configured by the gNB, for example, via RRC, MAC CE, and / or DCI.
[0084] 9A is a schematic diagram illustrating a multi-panel transmission scheme in multi-TRP operation according to an exemplary embodiment of the present invention.

Referring to FIG. 9B, the maximum output power may be set as a fixed power division scheme as shown in FIG. 8A or a configurable power division scheme as shown in FIG. 8B, for example, α 1 =0.5 and α 2 = 0.5. The UE receives power allocation related configuration in the DCI. The configuration is, for example, α 1 = 0.7 and α 2 You may indicate =0.5.
[0087] In one embodiment, the UE may select at least one pair {α 1 ,α 2} may be set with {α 1 ,α 2 Each pair of} may be associated with at least one code point of a new field for flexible panel-specific maximum output power adjustment. The new field may be included in the DCI, for example for DL assignment or UL grant.

Referring to FIG. 11B, for a DG PUSCH of one-shot adjustment, for example, DCI#1 (UL grant) associated with CORSETPoolIndex#0 includes a new field with a code point, for example, "011". Then, one PUSCH directed to TRP1 by DCI#1 is P CMAX,C1 =(α 1 =0.7) P CMAX,C It is scheduled in.
[0093] FIG. 12A is a schematic diagram illustrating a multi-panel transmission scheme in multi-TRP operation according to an exemplary embodiment of the present invention.

Referring to Figure 22A, the mapping table between code points and PDCCH monitoring coordination indicators shows the following: The code point "00" indicates that PDCCH monitoring is not skipped. The codepoint "01" represents skipping monitoring for the first duration. The code point "10" represents skipping monitoring for the second duration. The code point "11" represents a skip of monitoring for the third duration. The first, second and third durations may be three durations of different lengths of time.
[0121] For example, Figure 22B is a schematic diagram illustrating the time relationship of PDCCH monitoring according to one exemplary embodiment of the present invention. Referring to Figure 22B, a code point other than "0" or "00", for example, is set in the PDCCH monitoring adjustment indication field shown in Figure 22A of DCI#1. 0 ~Time T 1 The duration up to is used to stop / skip PDCCH monitoring.
[0122] In one embodiment, a UE may be configured with at least one PDCCHSkippingDurationList (e.g., a first PDCCHSkippingDurationList and / or a second PDCCHSkippingDurationList) or the UE may be provided with at least one PDCCHSkippingDurationList, where the first PDCCHSkippingDurationList may be associated / configured with a first value of CORSETPoolIndex and / or the second PDCCHSkippingDurationList may be associated / configured with a second value of CORSETPoolIndex.
[0123] In one embodiment, if the UE receives a DCI associated with a value of CORSETPoolIndex, the UE may perform PDCCH skipping. The skipped PDCCH may be associated with the value of CORSETPoolIndex. The duration indicated by the PDCCH monitoring adjustment indication field in the DCI associated with the value of CORSETPoolIndex (e.g., CORSETPoolIndex#0) may be associated with a corresponding PDCCHSkippingDurationList (e.g., the first PDCCHSkippingDurationList).
[0124] For example, Table (4) is a mapping table between code points and PDCCH monitoring adjustment instructions.
[0125] Table (4) [Table 5]
[0126] In one embodiment, the UE may be configured with at least one PDCCH skip duration (e.g., a first PDCCHSkippingDurationList and / or a second PDCCHSkippingDurationList), where the first PDCCHSkippingDurationList is a first pair {α 1 = e.g. 0,α 2 = 1}, and / or the second PDCCH SkippingDurationList may be associated with / set to a second pair {α 1 = For example, 1, α 2 = 0}. In one embodiment, when the UE performs PDCCH skipping associated with the first PDCCHSkippingDurationList (or the second PDCCHSkippingDurationList), the UE may associate / set the first pair {α 1 = e.g. 0,α 2 = e.g. 1} (or the second pair {α 1 = e.g. 0,α 2 = e.g. 1}) may perform a UL transmission and may trigger an M-TRP PHR.

For example, FIG. 24A is a schematic diagram illustrating single TRP operation with one TRP off according to one exemplary embodiment of the present invention, and FIG. 24B is a schematic diagram illustrating the time relationship of power allocation according to one exemplary embodiment of the present invention. Referring to FIG. 24A and FIG. 24B, the DCI skips PDCCH associated with, e.g., CORSETPoolIndex#1 for a duration in the PDCCH monitoring adjustment indication field, e.g., N slots / symbols / ns (N is an integer). The duration from the indicated time T0 to time T1 is used to stop / skip PDCCH monitoring associated with, e.g., CORSETPoolIndex#1.
[0130] In one embodiment, when the UE performs PDCCH skipping associated with the first PDCCHSkippingDurationList (or the second PDCCHSkippingDurationList), the UE selects a first pair {α 1 = e.g. 0,α 2 = e.g. 1} (or the second pair {α 1 = e.g. 0,α 2= e.g. 1}) and may trigger an M-TRP PHR. For example, Figure 24C is a schematic diagram illustrating the triggering of a power headroom report according to one exemplary embodiment of the present invention. See Figure 24C, for example, an S-TRP operation is performed because TRP#2 is off. The information that TRP#2 is off may be sent to TRP#1 by triggering an M-TRP power headroom report.

Referring to FIG. 40, the UE allocates the first PUSCH (maximum panel specific power P CMAX,C1 A first transmit power P 1 ) and the first PUSCH and the second PUSCH (having a second transmission power P 2 ) overlap completely / partially in the time domain in the same BWP / CC (step S4001). 1 +P 2 >P CMAX,C It may be determined whether or not (step S4002). 1 +P 2 ≦P CMAX,C If so, the UE will transmit the first PUSCH to P 1 and the second PUSCH is transmitted by P 2 (Step S4003).
[0196] P 1 +P 2 >P CMAX,C If so, the UE further 2 <PCMAX,C2 It may be determined whether or not (step S4004). 2 <P CMAX,C2 If so, the UE 1 P 1 ' and adjust (P 1 '+P 2 )≦P CMAX,C (Step S4005). Then, the UE 1 ' <P CMAX,C1 It may be determined whether or not (step S4006). 1 '≦P CMAX,C1 If so, the UE may transmit the first PUSCH to P 1 ', and the second PUSCH 2 (Step S4007).

[0198] P 2 <P CMAX,C2 If so, the UE 1 and P 2 Adjust the w 1 (P 1 +P 2 )≦P CMAX,C For example, as shown in FIG. 39A and FIG. 39B, the first PUSCH may be expressed as w 1 P 1 So, the second PUSCH 1 P 2(Step S4011).
[0199] In one embodiment, the two UL transmissions have the same channel priority and / or 1 +P 2 >P CMAX,C If so, the UE performs equal power reduction and (P' 1 =wP 1 )+(P' 2 =wP 2 )≦P CMAX,C It is acceptable to do so.

[0202] P 1 +P 2 >P CMAX,CIf so, the UE may further determine whether the UL transmissions have the same channel priority (step S4203). If the UL transmissions have different channel priorities, the UE may perform power allocation according to the channel priorities (step S4204). For example, the UE may discard a low-priority UL transmission or reduce a transmit power associated with a low-priority UL transmission.
[0203] If the UL transmissions have the same channel priority, the UE may perform power allocation according to TRP / panel priority (step S4205), for example, as shown in FIG. 36B, or the UE may perform power allocation according to partition priority (step S4206), for example, as shown in FIG. 37A to FIG. 39B, or the UE may perform power allocation according to equal power reduction (step S4207), for example, as shown in FIG. 41.
