[0039] In conventional communication systems, for single-cell operation with two UL carriers or operation with carrier aggregation (CA), the total UE transmit power of UL transmissions (e.g., PUSCH or PUCCH or PRACH or SRS transmissions) on the serving cell within the frequency range in the corresponding transmission occasion i exceeds In the case of Identifies the maximum transmission power P for FR1 and FR2 in transmission scenario i CMAX (i), the UE allocates power to the UL transmission according to a predetermined priority order so that the total UE transmit power in each symbol of transmission occasion i for the frequency range is less than or equal to

[0040] Since MIMO is enhanced in terms of simultaneous UL transmission from multiple panels, where two PUCCHs or two PUSCHs can be sent simultaneously in one cell, the transmission power control rules need to be designed considering the simultaneous UL transmission operation. In addition to the impact on the cross-cell power reduction priority, it may also be necessary to define the priority for simultaneous UL transmission within a cell.

[0041] To address the above and other potential problems, embodiments of the present disclosure provide a power control scheme. The scheme involves prioritizing the allocation and reduction of transmission power for simultaneous UL transmissions in a single serving cell and parallel UL transmissions across multiple serving cells. Specifically, power control of simultaneous UL transmissions from multiple panels is achieved by allocating transmission power in the order of power allocation priorities of the corresponding UL transmissions. As a result, the performance of UL transmission operations is improved.

[0042] Figure 1 An example network system 100 is illustrated in which example embodiments of the present disclosure may be implemented. Figure 1 As shown in , the communication network 100 may include a terminal device 110 and a network device 120. The network device 120 is associated with at least two transmission reception points (TRPs) 122, 124, or may include two transmission reception points (TRPs) 122, 124, or may be composed of at least two transmission reception points (TRPs) 122, 124, wherein the service cell 102 is configured with the TRPs 122, 124, and the service cell 104 is configured with the TRP 124.

[0043] The network system 100 may be a multi-TRP system, and the terminal device 110 may operate with multiple UL carriers or with carrier aggregation (CA). In the case of CA, the serving cell 102 may also be referred to as a primary cell or PCell, and the serving cell 104 may also be referred to as a secondary cell or SCell. In some embodiments, the network device 120 is composed of one or both of the TRPs 122 and 124. Alternatively, in other embodiments, the network device 120 is separated from the TRPs 122 and 124 and manages the TRPs 122 and 124.

[0044] The terminal device 110 supports simultaneous transmissions, such as simultaneous physical uplink control channel (PUCCH) transmissions and physical uplink shared channel (PUSCH) transmissions across multiple panels, and the simultaneous transmissions are scheduled by a single DCI. In the context of the present disclosure, the term "simultaneous transmission" refers to at least two PUCCH transmissions or at least two PUSCH transmissions sent on the same (serving) cell. Simultaneous UL transmissions can be sent based on space division multiplexing (SDM), frequency division multiplexing (FDM), or single-frequency network (SFN) schemes. For the purpose of discussion, various schemes are briefly described below.

[0046] ●In the FDM-A scheme, different parts of the frequency domain resources of a PUSCH transmission occasion are sent from different UE panels.

[0047] ● In the FDM-B scheme: two PUSCH transmission occasions of the same transport block (TB) with the same or different RV are sent from different UE panels on non-overlapping frequency domain resources and the same time domain resources.

[0048] ● In SFN-based transmission scheme: all the same layers or DMRS ports of a PUSCH are sent from two different UE panels at the same time.

[0049] ● In the SDM repetition scheme, two PUSCH transmission occasions with different RVs for the same TB are sent simultaneously from two different UE panels.

[0050] In the context of the present disclosure, the terms UL beam, spatial relationship information, UL Transmission Configuration Indicator (TCI) state, joint or common TCI state, spatial filter, power control information, power control parameter set, UE panel or panel ID, quasi-co-location information type D (or any other type, such as type A, B or C) can be used interchangeably. The UE panel can be identified by an index of a UE capability value set or a panel ID. Alternatively or additionally, the panel can be identified or associated by at least one Reference Signal (RS) or simply by a UL beam.

[0051] It should be understood that Figure 1 The number of network devices, TRPs, and terminal devices shown in FIG. 1 is given for illustrative purposes and does not imply any limitation. Communication network 100 may include any appropriate number of network devices and terminal devices.

[0052] Depending on the communication technology, the communication network 100 may be a Code Division Multiple Access (CDMA) network, a Time Division Multiple Address (TDMA) network, a Frequency Division Multiple Access (FDMA) network, an Orthogonal Frequency Division Multiple Access (OFDMA) network, a Single Carrier-Frequency Division Multiple Access (SC-FDMA) network, or any other network. The communications discussed in the network 100 may conform to any suitable standard, including but not limited to New Radio Access (NR), Long Term Evolution (LTE), Evolved LTE, Advanced LTE (LTE-A), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), cdma2000, and Global System for Mobile Communication (GSM), etc. In addition, the communications may be performed according to any generation of communication protocols currently known or developed in the future. Examples of communication protocols include, but are not limited to, first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) communication protocols. The techniques described herein can be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For clarity, certain aspects of the techniques are described below for LTE, and LTE terminology is used in much of the description below.

[0053] The following will refer to Figures 2 to 6 The principles and implementations of the present disclosure are described in detail. Figure 2 1 shows a signaling diagram illustrating an example process 200 for transmission power control according to some example embodiments of the present disclosure. The process 200 may involve Figure 1 For discussion, reference will be made to the terminal device 110 and the network device 120 shown in FIG. Figure 1 Process 200 is described.

[0054] In process 200, terminal device 110 is capable of operating with simultaneous multi-panel UL transmissions on one or both of cells 102 and 104. In some example embodiments, terminal device 110 may attempt to send multiple UL transmissions that at least partially overlap in the time domain. Each of the multiple UL transmissions may be associated with a respective priority index.

[0055] In some example embodiments, network device 120 may send (205) an indication of a priority order associated with a first group of simultaneous transmissions on cell 102 via at least one of an RRC message, a MAC CE, or a DCI. The first group of simultaneous transmissions includes at least: a first transmission and a second transmission that partially overlap at least in the time domain. In some other embodiments, such a priority order associated with the first group of simultaneous transmissions may be predefined or specified for both terminal device 110 and network device 120. Therefore, step 205 is optional for process 200.

[0056] Figure 3 and Figure 4 An example of UL transmission for multiple serving cells according to some example embodiments of the present disclosure is shown. Figure 3 As shown in FIG. 1 , a first set of simultaneous UL transmissions includes a first transmission 310 and a second transmission 320, which are scheduled by a single DCI on the cell 102. The cell 102 may be configured with multiple resource sets, such as an SRS resource set, a CORESET, etc. In addition, a third transmission 330 is scheduled by another DCI on the cell 104. The first set of simultaneous UL transmissions 310 and 320 and the third transmission 330 at least partially overlap in the time domain.

[0057] like Figure 4 As shown in FIG. 1 , a first set of simultaneous UL transmissions includes a first transmission 410 and a second transmission 420, which are scheduled by a first DCI on cell 102. In addition, a second set of simultaneous UL transmissions includes a fourth transmission 440 and a fifth transmission 450, which are scheduled by a second DCI on cell 104. Cells 102 and 104 may be configured with multiple resource sets. The first set of simultaneous UL transmissions 410 and 420 overlaps at least partially with the second set of simultaneous UL transmissions 440 and 450 in the time domain.

[0058] Before sending the plurality of UL transmissions, the terminal device 110 determines 210 whether the total transmission power of the plurality of UL transmissions exceeds a transmission power threshold. For example, the transmission power threshold may be defined as

[0059] As mentioned above, the total transmission power should be controlled below the transmission power threshold. If it is determined that the total transmission power exceeds the transmission power threshold in a transmission occasion, the terminal device 110 allocates 215 power to the multiple UL transmissions based on a priority order associated with the first group of simultaneous transmissions. In the context of the present disclosure, a transmission occasion may include multiple consecutive symbols within a time slot or across time slots.

[0060] In some example embodiments, the priority order may indicate a priority in terms of transmission power allocation and / or transmission power reduction.

[0061] The terminal device 110 sends 220 at least a portion of the plurality of UL transmissions to the network device 120. Transmission powers of the plurality of UL transmissions are allocated based on respective power allocation priorities such that a total transmission power of at least a portion of the plurality of UL transmissions is below a transmission power threshold.

[0062] The transmission power may be allocated in descending order of the respective power priorities of the plurality of UL transmissions until the total transmission power reaches the transmission power threshold. Thus, in some embodiments, when the total transmission power reaches the transmission power threshold, the terminal device 110 may discard the remaining transmissions of the plurality of UL transmissions that are not allocated transmission power. Additionally or alternatively, in some embodiments, a portion of the plurality of UL transmissions may be allocated with a reduced transmission power.

[0063] In some embodiments, the corresponding power priority may be determined based on the priority indexes of the multiple UL transmissions. To determine the priority of the transmission power allocation, in some embodiments, a simultaneous PUCCH or PUSCH transmission with a higher priority index is defined as having a priority of at least one step / level higher than the PUCCH or PUSCH transmission associated with the same higher priority index. Additionally or alternatively, in some embodiments, a simultaneous PUCCH or PUSCH transmission with a higher priority index may have a priority of at least one step / level lower than the PRACH transmission on the primary cell.

[0064] exist Figure 3 In the example shown in , if the first group of simultaneous transmissions 310 and 320 and the third transmission 330 are associated with the same priority index, the terminal device 110 may assign a higher power allocation priority to the first group of simultaneous transmissions 310 and 320 than to the third transmission 330. Additionally or alternatively, the first group of simultaneous transmissions 310 and 320 may be assigned a lower power allocation priority than a PRACH transmission on a primary cell of the terminal device 110.

[0065] In the case of CA, the terminal device 110 may prioritize power allocation for UL transmissions on cells with simultaneous UL transmissions, including but not limited to simultaneous PUCCH, or PUSCH, or PRACH, or SRS transmissions. In other words, for Figure 3 In the example shown in , the cell 102 having simultaneous UL transmissions 310 and 320 may be considered to have a higher priority than the cell 104 having no simultaneous UL transmissions.

[0066] In some embodiments, for Figure 3In the example shown in , the network device 120 manages the primary cell (i.e., cell 102) and the secondary cell without simultaneous transmission, i.e., the third transmission 330 on cell 104. If the first group of simultaneous transmissions 310 and 320, and the third transmission 330 are assigned the same power allocation priority, the terminal device 110 may prioritize the transmission power allocation for the first group of simultaneous transmissions 310 and 320 over the third transmission 330. The first group of simultaneous transmissions 310 and 320 may include at least one of simultaneous PUCCH transmissions, simultaneous PUSCH transmissions, simultaneous PRACH transmissions, or SRS transmissions.

[0067] In the case where a simultaneous PUCCH or PUSCH transmission is not associated with a higher priority index, the simultaneous PUCCH or PUSCH transmission may be assigned a higher power allocation priority than any PUCCH or PUSCH transmission with the same priority index. Figure 3 As shown in , in some embodiments where the first group of simultaneous transmissions 310 and 320 and the third transmission 330 are associated with the same priority index, the terminal device 110 may assign a higher power allocation priority to the first group of simultaneous transmissions 310 and 320 than to the third transmission 330 .

[0068] For simultaneous PUCCH or PUSCH transmissions with the same priority index, different levels of power allocation priority can be assigned by considering the content or usage of PUCCH / PUSCH, for example, aspects related to Hybrid Automatic Repeat Request (HARQ), Scheduling Request (SR), Link Recovery Request (LRR), Channel State Information (CSI), etc.

[0069] For Figure 4 In the scenario 400 shown in FIG. 4 , the multiple UL transmissions of the terminal device 110 include: a first group of simultaneous transmissions 410 and 420 on the cell 102, and a second group of simultaneous transmissions 440 and 450 on the cell 104. If the first group of simultaneous transmissions 410 and 420, and the second group of simultaneous transmissions 440 and 450 are associated with the same priority index, the terminal device 110 may determine the corresponding power allocation priority based on the contents of the first group of simultaneous transmissions and the second group of simultaneous transmissions.

[0070] In some example embodiments, power allocation priority levels may be assigned in the following descending order (ie, higher priority first):

[0071] ● Simultaneous PUCCH transmission with at least one of Hybrid Automatic Repeat request–Acknowledge (HARQ-ACK) information, Scheduling Request (SR), Link Recovery Request (LRR), or simultaneous PUSCH transmission with HARQ-ACK information;

[0072] ● Simultaneous PUCCH transmission with CSI, or simultaneous PUSCH transmission with CSI;

[0073] • Simultaneous PUSCH transmissions without HARQ-ACK information or CSI, or simultaneous PUSCH transmissions on the primary cell (eg, for a Type 2 random access procedure).

[0074] For simultaneous UL transmissions within a single cell, the terminal device 110 may be configured (e.g., via RRC), or indicated (e.g., using existing or new fields / bits in DCI and / or MAC CE), or assigned priorities for power allocation / reduction.

[0075] In such Figure 3 In the scenario 300 shown in , the cell 102 is configured with a first resource set and a second resource set, and the terminal device 110 may prioritize the transmission power allocation of one of the first transmission 310 and the second transmission 320 corresponding to the first resource set over the other of the first transmission 310 and the second transmission 320 corresponding to the second resource set. The index of the first resource set may be higher or lower than the index of the second resource set, and it may be predefined or specified whether to prioritize UL transmissions associated with a higher resource set index or a lower resource set index. Alternatively, the terminal device 110 may prioritize UL transmissions associated with a given resource set index, and may receive an indication of the given resource set index via at least one of an RRC message, a MAC CE, or a DCI.

[0076] In the case where the first resource set and the second resource set may be CORESETs, the terminal device 110 may prioritize UL transmissions corresponding to a given CORESET pool index. Additionally or alternatively, in some example embodiments, the terminal device 110 may prioritize UL transmissions corresponding to relatively lower CORESET pool indexes, or alternatively, may prioritize UL transmissions corresponding to relatively higher CORESET pool indexes.

[0077] In the case where the first resource set and the second resource set may be SRS resource sets, the terminal device 110 may prioritize UL transmissions corresponding to a given SRS resource set. Additionally or alternatively, in some example embodiments, the terminal device 110 may prioritize UL transmissions corresponding to SRS resource sets with relatively higher indices, or alternatively, may prioritize UL transmissions corresponding to SRS resource sets with relatively lower indices.

[0078] Alternatively, in some embodiments, the terminal device 110 may prioritize UL transmissions corresponding to a given closed loop (or at least one closed loop parameter), or alternatively, may prioritize UL transmissions corresponding to a given open loop index (or at least one open loop parameter) for power control. In some cases, it may be indicated via DCI or MAC CE, or configured for the terminal device 110 (e.g., via RRC) to prioritize the corresponding UL transmissions for which given closed loop or given open loop index (or at least one corresponding parameter).

[0079] For Figure 3 In the scenario 300 shown in , in some example embodiments, the terminal device 110 allocates transmission power to one of the first and second transmissions 310 and 320 associated with a first cell identifier (e.g., a physical cell identifier (PCI)) over the other of the first and second transmissions associated with a second cell identifier (e.g., PCI), and the first cell identifier is higher or lower than the second cell identifier. In this case, it can be predefined or specified whether to prioritize UL transmissions with higher PCIs or UL transmissions with lower PCIs. In some cases, the terminal device 110 can prioritize UL transmissions associated with a given PCI (e.g., a PCI provided in a physical cell identifier or ID), and can receive an indication of the given PCI via at least one of an RRC message, a MAC CE, or a DCI.

[0080] In some example embodiments, the terminal device 110 may prioritize the transmission power allocation for one of the first and second transmissions 310 and 320 over the other based on a configuration stored locally at the terminal device. Alternatively, in some other embodiments, the terminal device 110 prioritizes the transmission power allocation for one of the first and second transmissions 310 and 320 over the other based on an indication from the network device 120. The indication may be carried, for example, in an existing field / bit, or a reserved field / bit, or a new field / bit in the DCI or MAC CE.

[0081] In some example embodiments, terminal device 110 may prioritize transmission power allocation to one of first transmission 310 and second transmission 320 associated with a first capability value set over the other associated with a second capability value set. The first capability value set may be higher or lower than the second capability value set.

[0082] In some example embodiments, the transmission power allocation to one of the first transmission 310 and the second transmission 320 is prioritized over the other based on the panel index or the UL beam indication. In the above case, the terminal device 110 may prioritize UL transmissions associated with a given capability value set (or flat panel), or with a relatively low or high capability value set index (or panel index).

[0083] In some example embodiments, the terminal device 110 may prioritize the transmission power allocation of one of the first transmission 310 and the second transmission 320 associated with a given TCI state, or set of TCI states.

[0084] In some example embodiments, the terminal device 110 may prioritize transmission power allocations for one of the first transmission 310 and the second transmission 320 that are associated with a TCI state or beam or reference signal or capability value setting having a larger or lower L1-RSRP, which may be reported by the terminal device 110 via a beam report.

[0085] In some example embodiments, the terminal device 110 prioritizes a transmission power allocation associated with a first Reference Signal Received Power (RSRP) for one of the first transmission 310 and the second transmission 320 over the other associated with a second RSRP. The first RSRP may be higher or lower than the second RSRP.

[0086] In some example embodiments, where the first transmission 310 corresponds to a first link and the second transmission 320 corresponds to a second link, and the path loss of the first link is higher than the second link, the terminal device 110 may prioritize the transmission power allocation for the first transmission 310 over the second transmission 320. In this case, the terminal device 110 may prioritize the UL transmission corresponding to the link, or TRP, or panel with the larger path loss.

[0087] For scenario 400, in an embodiment where first cell 102 is a primary cell and cell 104 is a secondary cell, terminal device 110 assigns a higher power allocation priority to a first set of simultaneous transmissions 410 and 420 for the primary cell than to a second set of simultaneous transmissions 440 and 450 for the secondary cell.

[0088] In addition, in some embodiments, the cell 102 is configured with a first resource set and a second resource set, and the cell 104 is configured with a third resource set and a fourth resource set. The first resource set and the third resource set may be the same or different resource sets. The second resource set and the fourth resource set may be the same or different resource sets. The first transmission 410 corresponds to the first resource set, the second transmission 420 corresponds to the second resource set, the fourth transmission 440 corresponds to the third resource set, and the fifth transmission 450 corresponds to the fourth resource set. In this case, for the primary cell, the terminal device 110 may allocate the transmission power of the first transmission 410 corresponding to the first resource set over the second transmission 420 corresponding to the second resource set. For the secondary cell, the terminal device 110 may allocate the transmission power of the fifth transmission 450 corresponding to the fourth resource set over the fourth transmission 440 corresponding to the third resource set.

[0089] In the case of single DCI operation, the first, second, third, and fourth resource sets may be SRS resource sets. In the case of multi-DCI operation, the first, second, third, and fourth resource sets may be CORESETs, where each set is identified by a CORESET pool index.

[0090] In case of inter-cell operation for scenario 400, UL transmissions corresponding to a given PCI may be prioritized, where there may be one PCI provided with the physical cell identity, and another PCI (for so-called non-serving cells).

[0091] In some embodiments where the first group of simultaneous transmissions 410 and 420 and the second group of simultaneous transmissions 440 and 450 are associated with the same priority index, the terminal device 110 may determine corresponding power allocation priorities based on the contents of the first group of simultaneous transmissions 410 and 420 and the second group of simultaneous transmissions 440 and 450.

[0092] According to an exemplary embodiment of the present disclosure, a power control scheme is provided for simultaneous UL transmissions across cells and / or within a single cell. Specifically, the power control scheme enables prioritization of transmission power allocation and / or reduction, thereby primarily considering simultaneous UL transmissions within a cell and prioritizing / protecting more important UL transmissions. Therefore, the performance of UL transmission operations is improved.
