[0231] FIG. 2 is an interaction diagram of a power determination method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a power determination method for the communication system 100, and the above method comprises:

[0232] Step 2101, the network device sends first signaling.

[0233] Optionally, the network device can send first signaling to the terminal, and the terminal can receive the first signaling.

[0234] Optionally, the first signaling can be used to indicate an initial transmission power of the downlink reference signal.

[0235] In some embodiments, the first signaling can be Radio Resource Control (RRC) signaling.

[0236] In some embodiments, the downlink reference signal can include at least one of the following: a Synchronization Signal Block (SSB), a Channel-state information reference signal (CSI-RS). Optionally, the SSB downlink reference signal can include at least one of the following: a primary synchronization signal (PSS) in the SSB, a secondary synchronization signal (SSS) in the SSB, a Demodulation Reference Signal (DMRS) of a Physical Broadcast Channel (PBCH) in the SSB.

[0237] In some embodiments, the "transmission power" mentioned above can be understood as, for example, the energy of the resource element (RE) occupied by the downlink reference signal, i.e., the energy per resource element (EPRE).

[0238] Optionally, in some embodiments, a same type of downlink reference signal can correspond to multiple downlink reference signal indexes, for example, a downlink reference signal SSB can correspond to multiple different SSB indexes, and a downlink reference signal CSI-RS can correspond to multiple different CSI-RS indexes. Different downlink reference signal indexes (e.g., different SSB indexes or different CSI-RS indexes) in a same cell can correspond to a same transmission power, for example, all SSB indexes can adopt a same transmission power, or all CSI-RS indexes can adopt a same transmission power. In other embodiments, different downlink reference signal indexes (e.g., different SSB indexes or different CSI-RS indexes) in a same cell can correspond to different transmission powers, for example, different SSB indexes can adopt different transmission powers, or different CSI-RS indexes can adopt different transmission powers.

[0239] Optionally, when different downlink reference signal indexes in a same cell correspond to a same transmission power, the method of indicating the initial transmission power of the downlink reference signal by the first signaling can be that the first signaling indicates at least one of the following:

[0240] the initial transmission power of the SSB;

[0241] a power difference between the initial transmission power of the CSI-RS and the initial transmission power of the SSB.

[0242] Optionally, the initial transmission power of the SSB can be the initial transmission power of all SSB indexes; and the power difference between the initial transmission power of the CSI-RS and the initial transmission power of the SSB is used to determine the initial transmission power of the CSI-RS in combination with the initial transmission power of the SSB, and the initial transmission power of the CSI-RS can be the initial transmission power of all CSI-RS indexes.

[0243] Optionally, when the first signaling is RRC signaling, the initial transmission power of the SSB can be indicated by ss-PBCH-BlockPower in the RRC signaling; and the power difference between the initial transmission power of the CSI-RS and the initial transmission power of the SSB can be indicated by powerControlOffsetSS in the RRC signaling.

[0244] Optionally, when different downlink reference signal indexes in the same cell correspond to different transmission powers, the method in which the first signaling indicates the initial transmission power of the downlink reference signal can be: the first signaling is used to indicate the initial transmission power of different beams, which can include at least one of the following: beams corresponding to different SSB indexes, beams corresponding to different CSI-RS indexes. That is, the first signaling can indicate the initial transmission power corresponding to different SSB indexes, and / or indicate the initial transmission power corresponding to different CSI-RS indexes.

[0245] Optionally, when different downlink reference signal indexes in the same cell correspond to different transmission powers, the method in which the first signaling indicates the initial transmission power of the downlink reference signal can be: the first signaling is used to indicate the initial transmission power corresponding to different SSB indexes, and / or indicate the power difference between the initial transmission power corresponding to different CSI-RS indexes and the initial transmission power corresponding to different SSB indexes.

[0246] Step 2102, the network device transmits second signaling.

[0247] Optionally, the network device can transmit the second signaling to the terminal, and the terminal can receive the second signaling.

[0248] Optionally, the second signaling can be used to indicate the power change value and / or the changed transmission power of the downlink reference signal.

[0249] In some embodiments, the second signaling can include at least one of the following: downlink control information (DCI) signaling, medium access control control element (MAC CE) signaling.

[0250] In some embodiments, the power change value of the downlink reference signal can include at least one of the following:

[0251] The power change value between the transmission power of the downlink reference signal and the previous changed transmission power;

[0252] The power change value between the transmission power of the downlink reference signal and the initial transmission power.

[0253] In some embodiments, the network device can transmit the second signaling at least once at different time instants, for example, the network device can transmit the second signaling to the terminal to indicate the power change value after each dynamic adjustment of the transmission power. The power change value can be positive or negative.

[0254] Optionally, the second signaling can indicate the power change value in the following manners:

[0255] an index of the downlink reference signal;

[0256] a first indication, which can be used to indicate the power change value and / or the changed transmission power of the downlink reference signal.

[0257] Optionally, the index of the downlink reference signal can be used to identify which downlink reference signal has its transmission power changed.

[0258] Optionally, the first indication can be a bit value. For example, a corresponding relationship between the power change value and different bit values can be set, and / or a corresponding relationship between the changed transmission power and different bit values can be set. For example, when the power change value is -1 decibel millivolt (dBm), the corresponding bit value is “0”; when the power change value is 1 dBm, the corresponding bit value is “1”; or when the power change value is 6 (dBm), the corresponding bit value is “00”; when the power change value is 10 dBm, the corresponding bit value is “01”. At this time, if the network device adjusts the transmission power, and the power change value of the downlink reference signal is 1 dBm, the first indication carried by the second signaling can be “1”; or if the network device adjusts the transmission power, and the changed transmission power is 10 dBm, the first indication carried by the second signaling can be “01”.

[0259] Therefore, the second signaling can not explicitly carry the specific power change value and / or the specific changed transmission power of the downlink reference signal, but can carry the first indication used to indicate the power change value and / or the changed transmission power. The carrying resource required by the first indication is much less than that required by the power change value and / or the changed transmission power, thereby greatly saving the communication resource.

[0260] Optionally, when the second signaling is DCI signaling, the DCI signaling can be group-common DCI signaling or UE-specific DCI signaling. The terminals that select the same beam can belong to the same user group, for example, the terminals that select the same SSB index or the same CSI-RS index can belong to the same user group; and different terminals in the same user group correspond to the same radio network temporary identifier (RNTI), which can be determined by the network device based on implementation.

[0261] Optionally, when the second signaling is DCI signaling, the RNTI of the second signaling can be different from existing RNTI, and / or the DCI format of the second signaling can be different from existing DCI format, for example, the DCI format of the second signaling can be different from existing DCI format 2-9, and a new DCI format 2-x, such as x = 10, DCI format 2-10 is used

[0262] In step 2103, the terminal determines the transmission power of the changed downlink reference signal based on the first signaling and / or the second signaling.

[0263] Optionally, the terminal can determine the transmission power of the changed downlink reference signal based on the first signaling and / or the second signaling when the terminal receives the second signaling; or the terminal can first determine a first time, which is the application time of the second signaling, and then determine the transmission power of the changed downlink reference signal based on the first signaling and / or the second signaling at the first time.

[0264] In some embodiments, when the second signaling is MAC CE signaling, the first time can be, for example, x time units after the hybrid automatic retransmission request acknowledgement (HARQ-ACK) feedback by the terminal; optionally, the HARQ-ACK is feedback by the terminal for a physical downlink shared channel (PDSCH) used to carry the second signaling. Optionally, the time unit can include at least one of the following: second, millisecond, time slot, symbol, etc.

[0265] In other embodiments, when the second signaling is DCI signaling, the first time can be, for example, y time units after the terminal receives a physical downlink control channel (PDCCH) used to carry the second signaling. Optionally, the y time units can include at least the time for the terminal to demodulate the PDCCH.

[0266] Optionally, in some embodiments, the method for determining the transmission power of the downlink reference signal after the change by the terminal based on the first signaling and / or the second signaling can comprise: when the power change value of the downlink reference signal is the power change value between the transmission power of the downlink reference signal and the transmission power after the previous change, the terminal can determine the transmission power after the change at the moment based on the power change value of the downlink reference signal indicated by the second signaling and the transmission power after the previous change, for example, the transmission power after the change at the moment can be the sum or difference between the power change value and the transmission power after the previous change; when the power change value of the downlink reference signal is the power change value between the transmission power of the downlink reference signal and the initial transmission power, the terminal can determine the transmission power after the change based on the power change value of the downlink reference signal indicated by the second signaling and the initial transmission power, for example, the transmission power after the change can be the sum or difference between the power change value and the initial transmission power.

[0267] For example, assuming that the power change value of the downlink reference signal indicated by the second signaling is the power change value between the transmission power of the downlink reference signal and the transmission power after the previous change, and the terminal determines the initial transmission power of SSB#1 to be P=P0 based on the first signaling, the terminal receives the second signaling to determine the power change value of SSB#1 to be P_diff_1 at t1, and then the terminal determines the transmission power after the change of SSB#1 to be P’=P-P_diff_1=P0-P_diff_1. After a period of time, the terminal receives the second signaling to determine the power change value of SSB#1 to be P_diff_2, and then the terminal determines the transmission power after the change of SSB#1 to be P”=P’-P_diff_2=P0-P_diff_1-P_diff_2.

[0268] For example, assuming that the power change value of the downlink reference signal indicated by the second signaling is the power change value between the transmission power of the downlink reference signal and the initial transmission power, and the terminal determines the initial transmission power of SSB#1 to be P=P0 based on the first signaling, the terminal receives the second signaling to determine the power change value of SSB#1 to be P_diff_1 at t1, and then the terminal determines the transmission power after the change of SSB#1 to be P’=P-P_diff_1=P0-P_diff_1. After a period of time, the terminal receives the second signaling to determine the power change value of SSB#1 to be P_diff_2, and then the terminal determines the transmission power after the change of SSB#1 to be P”=P0-P_diff_2.

[0269] For example, it is assumed that the second signaling indicates the transmission power of the downlink reference signal after the change, and the terminal determines that the initial transmission power of SSB #1 is P=P0 based on the first signaling, and the terminal receives the second signaling at time t1 to determine that the transmission power of SSB #1 after the change is P1, and then the terminal determines that the transmission power of SSB #1 after the change is P'=P1. After a period of time, the terminal receives the second signaling again to determine that the transmission power of SSB #1 after the change is P2, and then the terminal determines that the transmission power of SSB #1 after the change is P''=P2.

[0270] Optionally, after the terminal determines the transmission power of the downlink reference signal after the change, the terminal can determine the path loss based on the transmission power after the change and the actual received power of the downlink reference signal, and determine the transmission power of the uplink reference signal of the terminal based on the path loss, so that the transmission power of the uplink reference signal can resist the path loss, thereby ensuring that the network device can successfully receive and demodulate the uplink reference signal, and ensuring the communication stability.

[0271] In the above embodiment, the network device can send at least one of the initial transmission power, the power change value, and the transmission power after the change of the downlink reference signal to the terminal through the first signaling and the second signaling, respectively, so that the terminal can successfully determine the transmission power of the downlink reference signal after the change based on the first signaling and / or the second signaling. As can be seen, the present disclosure can realize dynamic indication of the power, so that when the transmission power of the downlink reference signal of different beams is dynamically adjusted in the NTN system, the adjusted transmission power can be successfully notified to the terminal by using the method of the present disclosure.

[0272] In the above embodiment, the network device can send the second signaling at different times, so that when the network device adjusts the transmission power of the downlink reference signal of different beams each time, the network device can send the second signaling to the terminal, so that the terminal can determine the transmission power after the change based on the second signaling in real time, realize real-time notification of the transmission power, and ensure the unified understanding of the transmission power by the terminal and the network device.

[0273] In the above embodiment, the terminal will also determine the application time of the second signaling, and will determine the transmission power after the change based on the second signaling at the application time, so as to ensure that the terminal uses the transmission power after the change at the appropriate time, ensure the accuracy of the use time of the transmission power after the change, and ensure the communication performance.

[0274] The power determination method related to the embodiments of the present disclosure can include at least one of steps 2101-2103. For example, step 2101 can be implemented as an independent embodiment, step 2102 can be implemented as an independent embodiment, step 2103 can be implemented as an independent embodiment, step 2101+S2102 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0275] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0355] In some embodiments, the above-mentioned method can include the method described in the above-mentioned embodiments of the communication system side, the terminal side, the network device side, etc., which will not be repeated here.

[0356] The power determination method related to the embodiments of the present disclosure can include at least one of steps 5101-5105. For example, step 5101 can be implemented as an independent embodiment, and step 5102 can be implemented as an independent embodiment, but not limited thereto.

[0358] The following is an exemplary introduction to the above-mentioned method.

[0359] The present disclosure proposes a method for dynamic beam power indication.

[0360] Optional example: indicate the change of power by absolute power value + relative power value

[0361] Optional example 1: the network dynamically changes the power of the downlink reference signal through downlink signaling

[0362] · Wherein the power can be understood as the energy of the RE occupied by the downlink reference signal, i.e. EPRE Energy Per Resource Element

[0363] · The downlink reference signal includes at least one of: SSB (PSS, SSS, DMRS in PBCH) and CSI-RS

[0364] Optional example 2: the network configures the absolute power value / initial power value of the downlink reference signal through RRC signaling

[0365] • The base station indicates the transmission power of SSB through RRC signaling of RRC parameter ss-PBCH-BlockPower; and indicates the transmission power difference between CSI-RS and SSB through powerControlOffsetSS, and the UE determines the transmission power of CSI-RS through the offset and the transmission power of SSB.

[0366] • The base station can indicate the power values for different beams through RRC signaling, and different beams can be represented by SSB index and CSI-RS index

[0367] • Optional example 3: The network indicates the change value of power through MAC CE or DCI signaling.

[0368] • In one embodiment, the second signaling is MAC CE signaling

[0369] • In one embodiment, the second signaling is DCI signaling

[0370] • Optional example 4: The UE determines the power value of the downlink reference signal based on the first signaling and the second signaling

[0371] • Optional example 5: The change value of power can be positive or negative

[0372] • Optional example 6: The UE can determine the power values at different times based on multiple second signaling sent by the network

[0373] • For example, the UE determines the transmission power of SSB#1 to be P=P0 based on the first signaling, and the UE receives the second signaling at time t1 to determine the change value of the power of SSB#1 to be P_diff_1, so the UE determines the power of SSB#1 to be P'=P-P_diff_1=P0-P_diff_1. After a period of time, the UE receives the second signaling to determine the change value of the power of SSB#1 to be P_diff_2, so the UE determines the power of SSB#1 to be P''=P'-P_diff_2=P0-P_diff_1-P_diff_2.

[0374] • Optional example 7: The second signaling contains at least one of: beam index, relative power value

[0375] • The relative value of power can also be an index, which corresponds to one of a plurality of different power difference values defined by RRC

[0376] • Optional example 8: When the second signaling is DCI signaling,

[0377] • In one embodiment, the DCI signaling is group-common DCI

[0378] • In one embodiment, the UE group is the UEs selecting the same SSB index

[0379] • In one embodiment, the base station assigns the same RNTI to the UEs belonging to the same beam (SSB index) (base station implementation)

[0380] • In one embodiment, the DCI is scrambled with a special RNTI

[0381] • In one embodiment, the DCI uses a new DCI format 2-x, different from DCI format 2-9

[0382] • In one embodiment, the DCI signaling is UE-specific DCI

[0383] • Optional example 9: UE application time for changed power

[0384] • The second signaling is a MAC CE, and the UE applies the new power value after x time units after the UE feeds back the HARQ-ACK for the PDSCH containing the MAC CE

[0385] The second signaling is a DCI, and the UE applies the new power value after y time units after the UE receives the PDCCH. Y includes the time for the UE to demodulate the PDCCH.
