[0005] However, in scenarios where uplink and downlink decoupling is implemented, some Transmission and Receiving Points (TRPs) can only receive uplink signals but not transmit downlink signals. Therefore, the terminal can only determine the transmit power used for uplink transmission based on the downlink signals of other adjacent TRPs, which results in poor accuracy in the determined transmit power.

[0034] The power determination method, apparatus, terminal, network-side equipment, and medium provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0035] Currently, dense TRPs can be deployed on the network side to improve uplink coverage and throughput. Figure 2 shows a schematic diagram of a TRP deployment. As shown in Figure 2, to save TRP deployment costs, TRP21 and TRP22 are allowed to only receive data without sending data, making it easier to select sites for TRP deployment. From the perspective of network energy conservation, allowing TRPs to shut down downlink transmission links also brings certain benefits. In scenarios with dense uplink traffic, uplink transmission no longer relies on downlink reference signal measurement and assistance, which can also save reference signal overhead to a certain extent.

[0036] In TRP deployment, it is more important to control the terminal's transmit power.

[0037] 1. The significance of power control includes:

[0038] 1. Maintain power: Adjust the power according to the distance between the terminal and the base station to ensure that the power of all terminal signals reaching the base station is close;

[0039] 2. Improve performance: Dynamically adjust power according to channel changes, enabling accurate and rapid power regulation;

[0040] 3. Reduce interference: Reduce adjacent channel power leakage, reduce interference between users and cells, and extend battery life.

[0041] Second, the power control is divided as follows:

[0042] 1. Uplink channel power control, including: Physical Uplink Shared Channel Power Control (PUSCH PC), Physical Uplink Control Channel Power Control (PUCCH PC), Sounding Reference Signal Power Control (SRS PC), and Physical Random Access Channel Power Control (PRACH PC);

[0043] 2. Power Headroom Report (PHR), mainly to assist base station scheduling;

[0044] 3. Power scaling (i.e., power scaling / sharing): The main purpose is to share power and ensure transmission of higher-priority cells / channels.

[0045] 3. Power control parameters include:

[0046] 1. P0: open-loop receiving end power target value. Generally, the larger P0 is, the higher the uplink transmission power and the higher the received signal to interference plus noise ratio (SINR).

[0047] 2. Path Loss (PL): This is path loss estimation, which is performed using the Path Loss Reference Signal (PLRS), which includes the Synchronization Signal Block (SSB) and the Channel State Information Reference Signal (CSI-RS). The terminal maintains multiple path loss estimates and uses them based on the index configured or indicated by the network.

[0048] 3. Alpha: Partial path loss compensation factor, ranging from [0, 1];

[0049] 4. PUSCH and SRS: When Alpha is 0, path loss is completely ignored. When Alpha is 1, path loss is fully compensated. In this case, the uplink power of the cell center terminal is too low (that is, the overall throughput is too low), and the uplink power of the cell edge terminal is too high (that is, the inter-cell interference is too large).

[0050] 5. PUCCH and PRACH: They do not require throughput but reliability, so Alpha is set to 1.

[0051] 6. f(l): Power control adjustment state value (i.e., power control adjustment state), divided into accumulation mode and absolute assignment mode;

[0052] 7. Closed Loop Index (CLI): The value is l=0 or l=1.

[0053] In R15, power control parameters include PUCCH PC parameters, SRS PC parameters, and PUSCH PC parameters.

[0054] Among them, PUCCH PC parameters include:

[0055] PLRS: configured in the Radio Resource Control (RRC) parameter PUCCH-PathlossReferenceRS;

[0056] P0: There are 8 pairs, i.e., their index qu = 0 to 7, and the value of qu is configured by the RRC parameter PUCCH-SpatialRelationInfo;

[0057] Alpha: PUCCH has no Alpha, or Alpha = 1;

[0058] CLI: Configured in the RRC parameter PUCCH-SpatialRelationInfo, with a value of 0 or 1.

[0059] SRS PC parameters include:

[0060] PLRS: indicated by the RRC parameter PathlossReferenceRS;

[0061] P0 and α: The index of the combination of P0 and α is qs. P0 and α are parameters configured in SRS-ResourceSet and BWP level configuration parameters.

[0062] CLI: If SRS PC is associated with PUSCH PC (indicated by higher-layer signaling srs-PowerControlAdjustmentStates), SRS PC is determined based on PUSCH; otherwise, SRS uses independent power control and l=0 (which can only be achieved through downlink control information (DCI) 2_3).

[0063] PUSCH PC parameters include:

[0064] PLRS: Path loss estimate measured by RS with index qd, which is indicated by the high-layer signaling PUSCH-PathlossReferenceRS, qd = 0 to 3; PUSCH-PathlossReferenceRS contains an identity document (ID) and an RS, which can be an SSB or CSI-RS. If there is no PUSCH-PathlossReferenceRS, the SSB contained in the master information block (MIB) is used; during PUSCH transmission, when the terminal has SRI-PUSCH-PowerControl with different qds, for DCI format 0_1 ​​containing SRS resource indicator (SRS resource indicator, SRI) information, the terminal obtains the association between SRI and PUSCH-PathlossReferenceRS-Id through high-layer signaling (the two correspond one to one); if PUSCH is scheduled by DCI format 0_1 ​​containing a certain SRI, the qd of the corresponding PUSCH-PathlossReferenceRS is used; if DCI format 0_0 and PUCCH is configured with spatial relation info, the qd corresponding to Rs in the spatial relation info of PUCCH is used; if DCI format 0_0 and PUCCH is not configured with spatial relation info, or DCI format 0_1 ​​does not have SRI information, or SRI-PUSCH-PowerControl is not configured, the RS with PUSCH-PathlossReferenceRS-Id of 0 is used for path loss estimation; for Msg3 PUSCH, the terminal uses the RS resource index qd of the corresponding PRACH; for ULRRC grant free, qd is configured by the upper layer. If not configured, the RS with PUSCH-PathlossReferenceRS-Id of 0 is used for path loss estimation;

[0065] P0 and Alpha: by P O-NOMINAL-PUSCH,f,c (j) and P O-UE-PUSCH,b,,f,c(j); the former has no subscript b and is the cell-common carrier-level component (-202, -200, ..., 22, 24dBm), and the latter is the bandwidth part (BWP) level component (-16, -15, ..., 14, 15) independently configured by the terminal; the latter is configured in pairs with Alpha, with a total of 32 pairs, called P0-PUSCH-AlphaSet; j = 0, used for RRC not configuring P0-PUSCH-AlphaSet, or for Message 3PUSCH, the specific value is assigned by the relevant high-level signaling (preambleReceivedTargetPower, msg3-DeltaPreamble, msg3-Alpha); j = 1, used for URLLC grant free transmission, the specific value is assigned by the ConfiguredGrantConfig related high-level signaling; j = 2 to 31: related to Grant-based transmission, different j can be configured for different beams; for DCI format 0_1 contains SRI information. The terminal obtains the association between SRI and AlphaSet Id through the high-layer signaling SRI-PUSCH-PowerControl (the two correspond one to one). If PUSCH is scheduled by DCI format 0_1 ​​containing a certain SRI, the AlphaSet with the corresponding ID is used. If DCI format 0_1 ​​does not contain SRI information or DCI format 0_0 or SRI-PUSCH-PowerControl is not configured, the first P0-PUSCH-AlphaSet value of AlphaSet is used.

[0066] P b,f,c (i, l): Power control adjustment state value, where l is related to the SRI and is either 0 or 1. If tpc-Accumulation is configured by the upper layer, the power control adjustment mode is accumulation mode (-1, 0, 1, 3dB). If tpc-Accumulation is not configured by the upper layer, the power control adjustment mode is direct assignment mode (-4, -1, 1, 4dB). DCI 0_0, 0_1, and 2_2 contain this adjustment value.

[0067] For SRS power control, the protocol stipulates that the power control of the UE's SRS transmission can be performed through DCI format 2-3, that is, the closed-loop power control parameters can be adjusted. Among them, for format 2-3type A, each block (i.e., block) has multiple continuous transmit power control (Transmit Power Control, TPC) fields, each corresponding to an uplink carrier of the same terminal. Correspondingly, a TPC field is also 2 bits, and the closed-loop power control parameters also enable all SRS transmissions on an uplink carrier. For format 2-3type B, each block has only one TPC field of 2 bits for power control, and the closed-loop power parameters controlled by these 2 bits enable SRS transmissions of all usages on the uplink carrier of a UE corresponding to the block.

[0068] Currently, the terminal can first determine the transmit power used for uplink transmission based on the downlink signal sent by the network side device, such as the path loss reference signal; and then use the transmit power for uplink transmission to improve the uplink transmission performance.

[0069] However, in a scenario where uplink and downlink decoupling is implemented, some TRPs can only receive uplink signals but not transmit downlink signals. In this case, the terminal can only determine the transmit power used for uplink transmission based on the downlink signals of other adjacent TRPs. This results in poor accuracy in the determined transmit power and causes a loss in uplink transmission performance.

[0070] In order to solve the above problems, the embodiments of the present application provide a power determination method, apparatus, terminal, network-side equipment and medium. In the power determination method provided in the embodiments of the present application, the terminal can receive first information from the network-side equipment, and the first information includes relevant configuration information of the transmission power used for uplink transmission; and based on the first information, determine the first transmission power. Through this solution, since the terminal can determine the transmission power used for uplink transmission based on the relevant configuration information of the transmission power used for uplink transmission received from the network-side equipment, for some TRPs that can only perform uplink reception, when determining the transmission power used for uplink transmission, the terminal no longer needs to base it on the downlink signals of other adjacent TRPs, but can directly base it on the relevant configuration information received from the network-side equipment, thereby improving the accuracy of the determined transmission power.

[0071] The present invention provides a power determination method, and Figure 3 shows a flow chart of the power determination method provided by the present invention. As shown in Figure 3, the power determination method provided by the present invention may include the following steps 301 and 302.

[0072] Step 301: The terminal receives first information from a network-side device.

[0073] The first information includes configuration information related to the transmit power used for uplink transmission.

[0074] Optionally, in an embodiment of the present application, the above-mentioned first information may include different information contents. For example, the first information may include power control-related information of the uplink path loss measurement signal (specifically refer to a possible implementation method described below), or may include power parameter indication-related information of SRS / PUSCH / PUCCH (specifically refer to another possible implementation method described below).

[0075] A possible implementation

[0076] Optionally, in an embodiment of the present application, the above-mentioned first information may include at least one of first configuration information and first power information.

[0077] The first configuration information may include at least one of the following 1.1 to 1.4:

[0078] 1.1. At least one reference signal set and the purpose of each reference signal set;

[0079] 1.2. Power parameter information of at least one reference signal set;

[0080] 1.3. Time-frequency resource configuration of at least one reference signal;

[0081] 1.4. Power parameter information of at least one reference signal;

[0082] The first power information may include at least one of the following 2.1 to 2.3:

[0083] 2.1. At least one reference signal index, each reference signal index is used to identify a reference signal requiring power adjustment;

[0084] 2.2. At least one power adjustment state index, each power adjustment state index is used to determine a power adjustment state;

[0085] 2.3. At least one power adjustment information, each power adjustment information is used to determine a power adjustment value.

[0086] Exemplarily, taking the example of the first information including the first configuration information, the network device may configure at least one SRS resource set (i.e., the at least one reference signal set) for uplink path loss measurement for the terminal. The at least one SRS resource set includes X periodic SRS resources, and also configures spatial relationship information of the X SRS resources, such as an RO index or an SRS resource index for beam management. In addition, the network device may further indicate transmit power information for the X SRS resources. The transmit power information may be configured on a per-SRS resource set basis or on a per-SRS resource basis. The transmit power information may include a transmit power offset value of the SRS resource or SRS resource set compared to a target PRACH, where the target PRACH is obtained via a random access response (RAR) or MsgB in a random access channel (RACH) procedure. Alternatively, the transmit power of the SRS resource may be directly indicated to the terminal, for example, by directly indicating the terminal the fallback power value of the SRS based on the maximum transmit power.

[0087] To ensure SRS transmission performance, the network device can also configure an adjustment state index for the SRS for closed-loop power adjustment. Therefore, for TRPs without downlink reference signal transmission, the network device can configure an uplink RS to calculate path loss. The transmit power of the uplink RS can be directly configured and determined by the network device, for example, by referencing the transmit power corresponding to the PRACH to determine the uplink reference signal power to ensure uplink reference signal transmission performance.

[0088] As another example, taking the example where the first information includes the first power information, the terminal may receive network-side signaling DCI, which is used for closed-loop adjustment of SRS transmit power. The DCI includes multiple sets of power adjustment information, each set including information {power adjustment value} corresponding one-to-one to an SRS resource in an SRS resource set. The information is in ascending order of SRS resource index, and is used by the terminal to determine the power adjustment for each SRS resource. Each set of information may directly include {SRS index, power adjustment value}, which is used to adjust the power corresponding to the SRS resource.

[0089] In an embodiment of the present application, since the above-mentioned first information may include at least one of the above-mentioned first configuration information and the above-mentioned first power information, and the first configuration information and the first power information may also respectively include different information contents, the terminal can determine the transmit power through the relevant information of the power control of the uplink path loss measurement signal, thereby improving the flexibility of the terminal in determining the transmit power.

[0090] Optionally, in this embodiment of the present application, the power parameter information of each reference signal in the at least one reference signal or the power parameter information of each reference signal set in the at least one reference signal set may include at least one of the following 3.1 to 3.3:

[0091] 3.1. An offset value of a reference signal transmit power relative to a second transmit power, where the second transmit power includes at least one of the following: a transmit power determined based on a first reference resource, a maximum transmit power of a terminal;

[0092] Optionally, in an embodiment of the present application, the first reference resource may be SSB, PRACH or SRS, etc.

[0093] 3.2, Power adjustment status index;

[0094] 3.3. A second reference resource for determining the first transmit power.

[0095] Optionally, in an embodiment of the present application, the first transmission power is the transmission power used by the terminal to perform uplink transmission.

[0096] Optionally, in an embodiment of the present application, the second reference resource may be a PRACH resource or an SRS resource, etc.

[0097] In an embodiment of the present application, since the power parameter information of each of the above-mentioned reference signals or the power parameter information of each of the above-mentioned reference signal sets may include at least one of the above-mentioned 3.1 to 3.3, the composition form of the above-mentioned first information can be further enriched through different power parameter information, so that the terminal can further improve the flexibility of determining the transmission power based on the richer first information.

[0098] Another possible implementation

[0099] Optionally, in an embodiment of the present application, the first information may include: at least one set of second information, and at least one set of power adjustment values.

[0100] Among them, the above-mentioned second information is at least one of the following: beam information for uplink transmission, transmission power information for uplink transmission; each group of power adjustment values ​​in the above-mentioned at least one group of power adjustment values ​​is used to adjust the second power parameter in a group of beam information or a group of transmission power information.

[0101] Optionally, in an embodiment of the present application, the at least one set of second information may be carried by network-side signaling.

[0102] In an embodiment of the present application, since the above-mentioned first information may include the above-mentioned at least one set of second information and the above-mentioned at least one set of power adjustment values, the terminal can determine the transmit power through the power parameter indication of PUSCH / PUCCH, thereby further improving the flexibility of the terminal in determining the transmit power.

[0103] Optionally, in this embodiment of the present application, each set of second information in the at least one set of second information may include at least one of the following 4.1 to 4.5:

[0104] 4.1. Information about at least one beam used for uplink transmission;

[0105] 4.2. Information about at least one beam used for downlink transmission;

[0106] 4.3. Indication information of at least one reference signal used for uplink transmission path loss measurement;

[0107] 4.4. At least one first reference signal indication information, where each first reference signal indication information corresponds to a beam information for uplink transmission;

[0108] Optionally, in an embodiment of the present application, the first reference signal may be an uplink path loss reference signal, which may be obtained from downlink beam information paired with uplink beam information.

[0109] 4.5. At least one offset value compared to the transmit power of a fourth reference resource.

[0110] Optionally, in an embodiment of the present application, the fourth reference resource may be at least one of the following: an uplink RS corresponding to beam information, a PRACH, an SRS for uplink transmission, and a reference downlink signal for path loss measurement.

[0111] Optionally, in an embodiment of the present application, the above-mentioned beam information may include at least one of the following: quasi-co-site reference signal information, quasi-co-site reference channel information, antenna port information, and antenna panel information.

[0112] In an embodiment of the present application, since each group of the second information can include at least one of the above 4.1 to 4.5, each group of the second information can include different information content, thereby further enriching the composition form of the above first information. In this way, the terminal can further improve the flexibility of determining the transmission power based on richer first information.

[0113] Optionally, in this embodiment of the present application, the indication information of each reference signal may be used to indicate at least one of the following 5.1 to 5.3:

[0114] 5.1, an index of a reference signal;

[0115] 5.2, Path loss corresponding to a reference signal;

[0116] 5.3. Received power corresponding to a reference signal.

[0117] In the embodiment of the present application, since the indication information of each reference signal can be used to indicate at least one of the above 5.1 to 5.3, the flexibility of the indication content of the indication information of each reference signal can be improved.

[0118] Optionally, in the embodiment of the present application, the at least one set of power adjustment values ​​may be carried by a second signaling, and the second signaling may carry at least one of the following 6.1 and 6.2:

[0119] 6.1. At least one pair of third information, each pair of third information including a tag control information (TCI) identifier and a target power parameter adjustment value;

[0120] 6.2. At least one pair of fourth information, each pair of fourth information includes a TCI identifier and a target power parameter value.

[0121] Optionally, in an embodiment of the present application, the above-mentioned second signaling can be used to adjust the target power parameters in at least one set of beam / transmit power information.

[0122] In an embodiment of the present application, since the above-mentioned at least one set of power adjustment values ​​can be carried by the above-mentioned second signaling, and the second signaling can carry at least one of the above-mentioned 6.1 and 6.2, the at least one set of power adjustment values ​​can be carried by different second signaling, thereby improving the flexibility of transmitting the above-mentioned first information.

[0123] Step 302: The terminal determines a first transmit power based on the first information.

[0124] Optionally, in an embodiment of the present application, the terminal may determine the first transmit power specifically according to the configuration or instruction corresponding to the first information.

[0125] In the power determination method provided in the embodiment of the present application, since the terminal can determine the transmission power used for uplink transmission based on the relevant configuration information of the transmission power used for uplink transmission received from the network side device, for some TRPs that can only perform uplink reception, the terminal no longer needs to base the determination of the transmission power used for uplink transmission on the downlink signals of other adjacent TRPs, but can directly base the determination on the relevant configuration information received from the network side device, thereby improving the accuracy of the determined transmission power.

[0126] Furthermore, in the absence of downlink reference signal transmission, the network side equipment can configure an uplink reference signal for the terminal and obtain path loss information through uplink measurement and indicate it to the terminal to assist the U terminal in uplink power control, thereby ensuring the performance of uplink transmission.

[0127] Optionally, in an embodiment of the present application, in one of the possible implementations described above, the first information includes at least one of the first configuration information and the first power information. Exemplarily, after step 302, the power determination method provided in the embodiment of the present application may further include step 303.

[0128] Step 303: When the first condition is met, the terminal reports information related to the transmit power of the reference signal corresponding to the first information to the network side device.

[0129] The first condition mentioned above includes at least one of the following:

[0130] The transmission power change value of any reference signal exceeds the first threshold value;

[0131] The terminal receives a first signaling sent by a network side device, where the first signaling is used for at least one of the following: triggering reporting, activating a reference signal, switching a reference signal, switching a reference signal set, and activating a set of beam information;

[0132] The periodic reporting timer expires;

[0133] Activated new cells;

[0134] Switched to a new cell;

[0135] Uplink transmission resources are switched;

[0136] Switched SSB grouping.

[0137] Optionally, in an embodiment of the present application, the above-mentioned first threshold value may be any possible transmit power threshold value that is preconfigured, predefined, or agreed upon by a protocol.

[0138] Optionally, in an embodiment of the present application, the quasi co-location (QCL) relationship of the above-mentioned set of beam information may be associated with an uplink reference signal.

[0139] Optionally, in an embodiment of the present application, a change value of the first power parameter associated with the beam corresponding to the above-mentioned set of beam information may exceed a second threshold value.

[0140] Optionally, in an embodiment of the present application, the second threshold value may be any possible power parameter change threshold value that is preconfigured, predefined, or agreed upon by a protocol.

[0141] In an embodiment of the present application, since the terminal can report the transmission power-related information of the reference signal corresponding to the above-mentioned first information to the network side device when the above-mentioned first condition is met, the terminal does not need to always report the transmission power-related information, thereby saving signaling overhead and device power consumption.

[0142] Optionally, in this embodiment of the present application, the transmit power related information may include at least one of the following 7.1 to 7.6:

[0143] 7.1. Index of at least one reference signal;

[0144] 7.2. At least one maximum transmit power information;

[0145] 7.3. At least one power headroom information;

[0146] 7.4. At least one actual transmit power information;

[0147] 7.5. At least one transmit power change value information;

[0148] 7.6. An offset value of the transmit power compared to the third reference resource.

[0149] In an embodiment of the present application, since the above-mentioned transmission power-related information may include at least one of the above-mentioned 7.1 to 7.6, when the above-mentioned first condition is met, the terminal can report different transmission power-related information to the network side device, thereby improving the flexibility of the terminal in reporting transmission power-related information.

[0150] For example, the terminal can report the SRS transmit power (i.e., the transmit power-related information described above) for the network to calculate the uplink path loss or assist the network in determining the path loss change. To save reporting resources, the terminal will only report the SRS transmit power when the first condition described above is met. For example, when the SRS transmit power exceeds a threshold value, the terminal triggers the report. Of course, the report can also be triggered by the network-side device. For example, when the network-side device triggers an aperiodic SRS, a transmit power report can be triggered.

[0151] The present invention provides another power determination method, and Figure 4 shows a flow chart of the power determination method provided by the present invention. As shown in Figure 4, the power determination method provided by the present invention may include the following step 401.
