The base station is not limited to specific technical terms. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0022] For ease of understanding, the following describes some aspects of the embodiments of this application: I. Downlink (DL) Wake-up Signal (WUS) In communication systems, to further improve the power-saving performance of terminals, a Wireless Controller (WUS) based on the Physical Downlink Control Channel (PDCCH) is introduced. The WUS informs the UE whether it needs to listen to the PDCCH during the preset onDuration of Discontinuous Reception (DRX). When there is no data, the UE does not need to listen to the PDCCH during the onDuration period, which is equivalent to the UE being in a sleep state throughout the entire DRX long cycle, thus further saving power.

[0023] WUS signal is a type of Downlink Control Information (DCI), specifically DCI scrambled with a Power Saving (PS) Radio Network Temporary Identifier (RNTI) and cyclic redundancy check (CRC) (DCI with CRC scrambled by PS-RNTI, DCP). The PS-RNTI is a dedicated RNTI assigned to the terminal by the network-side device for power saving. The DCI scrambled with this RNTI carries the network-side device's wake-up or sleep instruction for the terminal. Based on this instruction, the terminal determines whether to start the onDuration timer and whether to perform PDCCH listening in the next DRX cycle.

[0024] II. SSB In LTE, terminals achieve synchronization through the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) broadcast by the base station. In NR, the concept of SSB (Secondary Synchronization Signal) emerges. SSB is formed by receiving the original PSS, SSS, Physical Broadcast Channel (PBCH), and Demodulation Reference Signal (DMRS) within four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, primarily for downlink synchronization.

[0025] The SSB period can be 5, 10, 20, 40, 80, or 160 ms, and this period is indicated in SIB1. If the terminal has not yet received SIB1 during the initial cell search, it will search for the SSB according to the default 20 ms period.

[0026] In NR, due to the misalignment of the synchronization grid and the frequency grid, the frequency deviation between the 0th subcarrier of the 0th RB of the 0th RB of the SSB and the 0th subcarrier of the lowest RB in the bandwidth part (BWP) that overlaps with the SSB is called kSSB.

[0027] In NR, the SSB can be used for initial terminal access or configured as a measurement reference signal for the terminal. The former is associated with SIB1 and is called the cell-defining SSB, while the latter is called the non-cell-defining SSB. SIB1 contains the necessary information for the terminal to camp on a cell; that is, the terminal can only camp on a cell when it finds the cell-defining SSB.

[0028] The terminal can obtain the value of kSSB by demodulating the Master Information Block (MIB) information carried by PBCH in the SSB. Taking frequency range (FR) 1 as an example, the value of kSSB is an integer between 0 and 31. When kSSB is in the range [0, 23], the SSB is a cell-defined SSB; when kSSB is in the range [24, 30], the SSB is a non-cell-defined SSB. In this case, the network-side device can use kSSB and the bits in the pdcch-ConfigSIB1 information field to jointly indicate the location of the cell-defined SSB; when kSSB=31, the terminal believes that there is no cell-defined SSB near the searched frequency point.

[0029] Considering that downlink transmission accounts for a large proportion of the uplink and downlink transmission energy consumption of network-side equipment (such as base stations), alternative energy-saving solutions for network-side equipment include shutting downlink transmission and increasing the common signal transmission cycle. When a network-side device enters this energy-saving mode, it needs assistance from other network-side devices or terminals to return to normal operation mode in a timely manner. One possible implementation is to wake up the network-side device in energy-saving mode via a terminal. Therefore, this application proposes a configuration determination method, in which the terminal configures and triggers the network-side device to return from a first operating mode to a second operating mode based on a corresponding wake-up signal, wherein the energy consumption of the first operating mode is lower than that of the second operating mode.

[0030] It should be noted that the first working mode in this application embodiment can be understood as an energy-saving mode, and the second working mode can be called a wake-up working mode. Specifically, the second working mode can be understood as an energy-saving mode or a normal working mode. For example, the terminal sends a signal according to the corresponding configuration to trigger the network-side device to return from the energy-saving mode to the normal working mode, or the terminal sends a signal according to the corresponding configuration to trigger the network-side device to return from energy-saving mode 1 to energy-saving mode 2, wherein the energy consumption of energy-saving mode 1 is lower than the energy consumption of energy-saving mode 2.

[0031] It should be understood that in energy-saving mode, network-side devices can shut down uplink and downlink transmissions, or only downlink transmissions, or downlink transmissions of some antennas, and can further reduce downlink transmission power. No further specific limitations are made here.

[0032] The configuration determination method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0033] like Figure 2 As shown, the configuration determination method provided in this application embodiment includes: Step 201: The terminal receives the first configuration from the first network-side device; Step 202, the terminal obtains a second configuration according to the first configuration. The second configuration is a signal configuration for the terminal to send a first signal. The first signal is used to trigger the second network-side device to switch from a first working mode to a second working mode, or to trigger the second network-side device to maintain the current working mode. The energy consumption of the second network-side device in the first working mode is less than the energy consumption in the second working mode. The current working mode is the first working mode or the second working mode. Wherein, the second configuration is the first configuration; or, the second configuration includes the first configuration and the third configuration agreed upon in the protocol, and both the first configuration and the third configuration include a portion of the signal configuration.

[0034] In this embodiment of the application, the first configuration can be understood as the transmission configuration of the first signal. The first signal can be called a wake-up signal or other uplink trigger signal, and no further limitation is made here.

[0035] Optionally, the first, second, and third configurations described above can all be understood as signal configurations of the first signal. In some embodiments, when a protocol-defined third configuration exists, if the signal wake-up signal configurations in the first and third configurations have different parameter configurations, then the second configuration can be understood as the complete set of the first and third configurations. For example, if the first configuration includes A and B, and the third configuration includes C and D, then the second configuration includes A, B, C, and D. If the signal configurations in the first and third configurations include some of the same parameter configurations, and at least some of the parameter values ​​in the same parameter configurations are different, then the parameter values ​​in the first configuration shall prevail. For example, if the first configuration includes A, B, and C1, and the third configuration includes C2 and D, then the second configuration includes A, B, C1, and D.

[0036] In some embodiments, the first network-side device can be understood as the network-side device associated with the cell that has entered energy-saving mode or the network-side device associated with the cell that is about to enter energy-saving mode, or it can be understood as the network-side device associated with the serving cell of the terminal.

[0037] It should be understood that, in the absence of a third configuration stipulated in the agreement, the aforementioned second configuration can be interpreted as the first configuration.

[0038] In this embodiment, a terminal receives a first configuration from a first network-side device. The terminal obtains a second configuration based on the first configuration. The second configuration is a signal configuration for the terminal to send a first signal. The first signal is used to trigger a second network-side device to switch from a first operating mode to a second operating mode, or to trigger the second network-side device to maintain its current operating mode. The energy consumption of the second network-side device in the first operating mode is less than its energy consumption in the second operating mode. The current operating mode is either the first operating mode or the second operating mode. The second configuration is the first configuration; or, the second configuration includes the first configuration and a third configuration agreed upon by a protocol, and both the first configuration and the third configuration include a portion of the signal configuration. Thus, since this embodiment clarifies the method for determining the signal configuration for the terminal to send the first signal, the network-side device can apply an energy-saving mode, thereby reducing its energy consumption.

[0039] Optionally, the second configuration includes at least one of the following signal configurations: First signal preset configuration; Time synchronization and time-frequency domain resource allocation; First signal sequence configuration; First signal power related configuration.

[0040] In this embodiment of the application, the preset configuration of the first signal can be understood as a general configuration of the first signal. For example, the preset configuration of the first signal includes at least one of the following: The effective area of ​​the first signal; The number of times the first signal is repeatedly sent; The repetition factor for repeatedly transmitting the first signal; The repetition time interval for repeatedly sending the first signal; The repetition period for repeatedly sending the first signal; The number of beams used by the second network-side device to receive the first signal.

[0041] Optionally, in some embodiments, the number of repetitions is equal to the product of the repetition coefficient and the number of beams. For example, if the number of repetitions is N, the repetition coefficient is k, and the number of beams is M, then the relationship between the three can be expressed as N = k * M, where N and M are both positive integers, and k is greater than 0.

[0042] In this embodiment, when the terminal needs to send a first signal, it can repeatedly send the first signal multiple times within a first signal transmission window according to the repetition count in the first configuration, thereby increasing the probability of successful reception by the network-side equipment associated with the cell in energy-saving mode. Furthermore, the repetition count of the terminal sending the first signal can be adjusted using a repetition coefficient. For example, if the first network-side equipment configuration or protocol-agreed configuration determines the repetition count in the signal configuration to be 4 and the repetition coefficient in the signal configuration to be 0.5, then the terminal will actually send the first signal 4 * 0.5 times, or 2 times, within a first signal transmission window.

[0043] It should be noted that one or more first signal transmission windows can be set for the transmission of the first signal, such as... Figure 3 As shown, the repetition time interval for repeatedly transmitting the first signal refers to the interval T1 between the start times of two adjacent repetitions of the first signal within a first signal transmission window. The repetition period for repeatedly transmitting the first signal can be understood as the interval T2 between the start times of two adjacent first signal transmission windows, or it can be the interval between the start times of the first first signal transmitted within two adjacent first signal transmission windows. For example, in some embodiments, if the second network-side device that transmits the first signal to the UE has multiple operating beams, such as eight beam directions, when the network-side device is in power-saving mode, if the terminal transmits the first signal to the second network-side device, the terminal may be located in any of the eight beam directions. Since the second network-side device needs to scan in each beam direction when it is working, the terminal needs to repeat the first signal at least eight times within a first signal transmission window to ensure that the transmitted first signal can be received by the second network-side device.

[0044] In some embodiments, a first signal transmission window may not be set for the transmission of the first signal. In this case, the repetition time interval or the repetition period of the first signal can be understood as the interval between the start times of two adjacent repetitions of the first signal.

[0045] Furthermore, the network-side device can configure a repetition coefficient k for the terminal, so that the terminal sends the first signal 8*k times within a first signal transmission window.

[0046] Optionally, in some embodiments, the time synchronization and time-frequency domain resource configuration includes at least one of the following: Time-domain reference cell identifier; The time-domain offset value relative to the time of the time-domain reference cell; The time-frequency resources of the first signal; The frequency points or frequency point list that can send the first signal.

[0047] In this embodiment, since the network-side equipment entering power-saving mode may completely shut down downlink transmission, the UE cannot establish downlink synchronization with the power-saving mode network-side equipment when sending the first signal to the power-saving mode base station. Therefore, the UE needs to synchronize the time axis for sending the first signal based on the time of the time-domain reference cell.

[0048] like Figure 4 As shown, assuming the first signal is WUS, cell 1 is the serving cell of the terminal, and cell 2 is an energy-saving mode cell. The UE establishes downlink synchronization based on the time timing of cell 1, at which time the UE's time domain reference cell is cell 1. If cell 1 and cell 2 are time-synchronized, the UE can directly use the timing T1 of cell 1 when sending WUS to cell 2; if cell 1 and cell 2 are not time-synchronized, cell 1 can configure a time domain offset value Toffset for the UE, then the timing T2 used by the terminal when sending WUS to cell 2 is the timing T1 of cell 1 plus the time domain offset value, that is: T2 = T1 + Toffset.

[0049] Optionally, sometimes the deviation in sending WUS to an energy-saving mode cell based on the serving cell's timing cannot be estimated. The network-side equipment can configure a nearby wake-up mode cell as a time-domain reference cell for the energy-saving mode cell, such as... Figure 5 As shown. Since cell 3 is closer to cell 2, using cell 3's timing as the time-domain reference cell for cell 2 would be more accurate. Therefore, cell 3 is configured as the time-domain reference cell for the UE to send WUS.

[0050] After the terminal completes time synchronization, when the UE determines that it needs to send WUS, it can send WUS according to the time and frequency resources in the wake-up signal configuration.

[0051] Optionally, in some embodiments, the wake-up signal sequence configuration includes at least one of the following: Random access preamble start index for the first signal; Random access preamble end index used for the first signal; Random access preamble index used for the first signal; The sequence index of the first signal; The number of seeds generated from the sequence of the first signal.

[0052] Optionally, the random access preamble start index or the random access preamble end index for the first signal is equal to the random access preamble index for the system message request.

[0053] Optionally, the first signal power related configuration includes at least one of the following: Expected received power in energy-saving mode of the community; Power reference cell reference signal transmission power; Power correction value; Initial transmission power of the first signal; Maximum transmission power of the first signal; Power increase value; Transmit power boost step size; Transmit power boost cycle; Power reference cell index.

[0054] Optionally, the first signal includes any of the following: an independent first signal sequence, an uplink probe reference signal, a random access preamble, message 1 (MSG1), message 3 (MSG3), and message A (MSGA).

[0055] In this embodiment of the application, messages 1, 3, and A can be understood as messages sent by the terminal in the random access procedure. For example, in a 4-step random access procedure, the terminal can send messages 1 and 3, and in a 2-step random access procedure, the terminal can send message A.

[0056] When the first signal is message 1, message 3 or message A, the network-side device may assume or consider that receiving message 1, message 3 or message A sent by the terminal indicates that the first signal has been received, thereby triggering the network-side device to restore from the power-saving mode to the normal working mode, or to switch from the first working mode to the second working mode.

[0057] For example, in some embodiments, the terminal sends message 1 to the network-side device, message 1 carrying a random access preamble for a first signal. Upon receiving message 2 in response from the network-side device, the terminal can send message 3 as the first signal. Message 2 may optionally explicitly carry an acknowledgment (ACK) for the random access preamble of the first signal, or implicitly indicate acknowledgment (ACK) by carrying an identifier for the random access preamble of the first signal. Message 3 may optionally carry an identifier of a second network-side device or an identifier of a group of second network-side devices for receiving the first signal. The group of second network-side devices includes multiple second network-side devices for receiving the first signal.

[0058] In some embodiments, the terminal sends message A to the network-side device, message A carrying a random access preamble for a first signal, whereby message A can serve as the first signal.

[0059] Optionally, after the terminal determines the second configuration, the method further includes: If the area where the terminal is located is outside the target effective area, the terminal obtains the target configuration from the third network side device, and the target effective area is the effective area of ​​the first signal included in the second configuration; The terminal updates the second configuration according to the target configuration.

[0060] In this embodiment of the application, the updated second configuration is the target configuration; or, the updated second configuration includes the target configuration and the third configuration agreed upon by the protocol, and both the target configuration and the third configuration include a portion of the signal configuration.

[0061] It should be understood that network-side devices can send target configurations to terminals via broadcast messages, system messages, higher-layer messages, or physical-layer messages. For example, network-side devices can send target configurations to terminals via Radio Resource Control (RRC), Medium Access Control Control Element (MAC CE), or DCI.

[0062] Optionally, the target configuration can be actively sent from the network-side device to the terminal, or it can be obtained by the terminal through a request. For example, in some embodiments, before the terminal obtains the target configuration from the third network-side device, the method further includes: The terminal sends a configuration request to the third network-side device, the configuration request being used to request the third network-side device to send the target configuration.

[0063] In this embodiment of the application, the terminal can send configuration requests via RRC, MAC CE, Uplink Control Information (UCI) messages, or broadcast messages.

[0064] It should be understood that the effective area in signal configuration can be based on different effective area levels, such as Tracking Area (TA) level, cell list level, cell group level, cell level, or beam level. For better understanding, refer to... Figure 6 As shown, this example illustrates the situation with WUS as the first signal, wake-up signal configuration as the signal configuration, and TA level as the effective area level.

[0065] Assuming the wake-up signal configuration applies at the TA level, and this configuration is effective within the same TA, when the terminal moves to a different TA, the terminal needs to retrieve the WUS configuration from the network-side device again. The specific process is as follows: Step S1, the UE receives the initial WUS configuration of cell 1 belonging to TA-1, including at least one of the following: wake-up signal preset configuration; time synchronization and time-frequency domain resource configuration; wake-up signal sequence configuration; wake-up signal power related configuration.

[0066] In step S2, the UE cell reselects or switches to cell 2, which belongs to TA-1. When the UE discovers that the TA code (TrackingAreaCode) of cell 2 is the same as the TrackingAreaCode of cell 1 by reading SIB or other means, it knows that cell 1 and cell 2 belong to the same TA and will consider that the initial WUS configuration is still effective and will not update the WUS configuration.

[0067] Step S3: At this point, cell 2 may or may not send WUS configuration information to the UE. Step S3 is optional. If cell 2 sends it, the UE can ignore it or not decode the WUS configuration information.

[0068] In step S4, the UE reselects or switches to cell 3, which belongs to TA-2. The UE finds that the TrackingAreaCode of cell 3 is different from that of cell 1 by reading SIB and other means, and then believes that the WUS configuration needs to be updated.

[0069] Step S5: If cell 3 does not send WUS configuration to the UE via system message or dedicated signaling, the UE can initiate a WUS configuration request to cell 3, requesting cell 3 to send WUS configuration for it. Step S5 is an optional step.

[0070] Step S6: The UE receives the WUS configuration of cell 3 belonging to TA-2.

[0071] Step S7: UE updates WUS configuration.

[0072] To better understand this application, the following detailed explanations are provided through specific examples.

[0073] In some embodiments, the WUS sent by the terminal can take the form of an independent wake-up signal sequence, an uplink probe reference signal, a random access preamble, message 1, message 3, and message A. When the WUS takes the form of message 1, message 3, and message A, it can be understood that the random access procedure itself is a wake-up procedure.

[0074] Optionally, when the WUS sent by the terminal is in the form of an independent wake-up signal sequence, the following two cases exist: In scenario 1, the WUS sequence set can be directly configured to the UE via SIB or RRC signaling. When the network-side device triggers the UE to send WUS, it can directly indicate a WUS sequence index to the UE, so that the UE knows which sequence to send WUS. When the UE triggers itself to send WUS, it can determine which sequence to send WUS based on the pre-configured WUS sequence index.

[0075] Scenario 2: WUS sequence generation can be based on a protocol-defined calculation formula. When the network-side device sends WUS configuration to the UE, it includes a WUS sequence generation seed number. The UE determines the WUS sequence to send based on the protocol-defined calculation formula and the WUS sequence generation seed number.

[0076] Optionally, when the WUS sent by the terminal is in the form of a Sounding Reference Signal (SRS), the following steps are included: Step S1: Cell 1 sends WUS configuration to UE, instructing UE to send time and frequency resources of SRS WUS when using SRS as WUS; In step S2, when the UE determines that it needs to send WUS, it sends WUS according to the SRS time-frequency resources configured by the network-side device in step S1.

[0077] Optionally, when the WUS sent by the terminal is in the form of a random access preamble, it includes the following cases: Case 3: Reuse the SI request preamble.

[0078] When sending System Message SIB1, the network-side device can carry the configuration required for the UE to initiate a System Message Request (SIrequest). This includes ra-PreambleStartIndex, an integer with a value between [0, 63], used to indicate the preamble from index ra-PreambleStartIndex to index 63. In other words, preambles with index numbers within [ra-PreambleStartIndex, 63] can be used in the SI request. This is equivalent to ra-PreambleStartIndex being the random access preamble start index used for the wake-up signal.

[0079] When the power-saving mode base station receives the random access procedure Msg1 initiated by the UE, if it finds that the preamble in Msg1 is SI request preamble, it is considered to have received WUS from the UE, and can then switch to wake-up mode.

[0080] Case 4: Allocate a random access preamble specifically for waking up network-side devices in power-saving mode to the UE.

[0081] In this scenario, after receiving the SI request, the network-side device needs to send a RAR (Random Access Response) to the UE and include the system message requested by the UE in the system message. When the UE receives the RAR, and the RAR only contains the Random Access Preamble ID (RAPID), it is considered an acknowledgment for the SI request from the network-side device.

[0082] However, the UE's act of sending WUS to the network-side device may only be to wake up the network-side device. The UE does not need the network-side device to send any system messages. Therefore, reusing the SI request preamble will cause the network-side device to send RAR and some unnecessary system messages, resulting in waste.

[0083] Therefore, the network-side equipment can allocate a randomaccess preamble (which can be called a WUS preamble) specifically for waking up the network-side equipment in power-saving mode for the UE. The WUS configuration carries the start index of the WUS preamble, WUS-PreambleStartIndex, and / or the end index, WUS-PreambleEndIndex. Thus, when the UE needs to send WUS, it can determine which preambles can be used as WUS preambles.

[0084] One implementation of the start and / or end position indices for WUS preambles is as independent indices, while another implementation associates them with ra-PreambleStartIndex. For example, using ra-PreambleStartIndex as the end position index of a WUS preamble, and then configuring a start position index WUS-PreambleStartIndex for the WUS preamble, preambles with index numbers between [WUS-PreambleStartIndex, ra-PreambleStartIndex] are used as WUS preambles, while preambles with index numbers within [ra-PreambleStartIndex, 63] are used for SI requests. This way, the usage of SIrequest preambles is not affected. For example, using ra-PreambleStartIndex as the starting position index of the WUS preamble, and then configuring a position index WUS-PreambleStartIndex for the WUS preamble, preambles with index numbers between [ra-PreambleStartIndex, WUS-PreambleIndex] or [WUS-PreambleIndex, 63] are used as WUS preambles, while the remaining preambles with index numbers within [ra-PreambleStartIndex, 63] are used for SI request preambles. Alternatively, WUS-PreambleIndex doesn't need to be configured; WUS-PreambleStartIndex is simply ra-PreambleStartIndex, as described in case 3.

[0085] When the power-saving mode base station receives a WUS preamble from the UE, it can switch to wake-up mode without responding to the WUS preamble. When the UE receives the SSB / SIB of the base station entering wake-up mode, it knows that the base station has been woken up from power-saving mode, without needing to confirm via RAR.

[0086] Optionally, when WUS is in the form of message 1, the following process is included: Step S1: The network-side device sends the PRACH configuration of the energy-saving mode cell to the UE; In step S2, when the UE determines that it needs to send WUS, it selects a PRACH resource to attempt to initiate random access to the energy-saving mode cell according to the Physical Random Access Channel (PRACH) configuration of the energy-saving mode cell configured in step S1.

[0087] Optionally, the power of the wake-up signal can be calculated as follows.

[0088] Assume the network-side equipment is configured with an energy-saving mode for the terminal, and the expected received power Ptarget for receiving WUS in the cell is calculated. The calculation method differs depending on the scenario: Calculation Method 1: For scenarios with channel reciprocity, if the energy-saving mode cell sends a measurement reference signal to the terminal, and the power Pref-tx of the measurement reference signal is as agreed in the protocol, or is informed to the UE by the network-side equipment through WUS configuration, and the UE receives a measurement reference signal with a power of Pref-rx, then the path loss from the energy-saving mode cell to the UE is: Ppathloss = Pref-tx – Pref-rx; Then the transmit power Pue-tx for UE transmitting WUS is: Pue-tx = Ptarget + Ppathloss = Ptarget + Pref-tx – Pref-rx.

[0089] Calculation Method 2: For scenarios with channel reciprocity, if the energy-saving mode cell completely shuts down its downlink transmission to save power, while a cell co-located with or adjacent to the energy-saving mode cell is still operating normally, then that cell can become the power reference cell for the UE to transmit WUS signals. However, a power correction value Pdelta needs to be introduced on top of Calculation Method 1, i.e., the UE's transmission power Pue-tx for transmitting WUS is: Pue-tx = Ptarget + Pref-tx – Pref-rx + Pdelta.

[0090] Assuming the cell in power-saving mode is in normal operating mode and there are no nearby cells that can be used as power reference cells, the UE's current serving cell can configure one or more of the following parameters for the UE via WUS configuration: WUS initial transmit power Pue-tx-init; WUS maximum transmit power Pue-tx-max; WUS transmit power boost step size (Pramp); WUS transmit power boosting cycle Tramp.

[0091] Optionally, when the UE determines that it needs to transmit WUS, it uses Pue-tx-init as the initial WUS transmission power Pue-tx. If, after each Tramp interval, no neighboring cell suitable for camping or handover is found, or if the second network-side device is not woken up, the WUS transmission power Prap is increased once. That is, the WUS transmission power after the UE increases the power is: Pue-tx = Pue-tx-init + Pramp; The UE then repeats the above strategy, increasing the power based on the previous transmission power, that is: Pue-tx = Plast + Pramp; The UE will stop increasing its power until the power Pue-tx calculated by the above strategy is greater than Pmax. Thereafter, Pmax will be used as the power for the UE to transmit WUS.

[0092] Optionally, when the UE needs to transmit WUS sequentially on different frequency points, the UE needs to determine the power of transmitting WUS after switching frequency points.

[0093] For example, in some embodiments, suppose the WUS configuration informs the UE that it can transmit WUS on two frequency points, such as frequency point one and frequency point two. Suppose the UE first transmits WUS on frequency point one with the initial power Pue-tx-init in the aforementioned WUS configuration, and after several power increases, it reaches P1. At this time, the UE switches to frequency point two to transmit WUS, then the UE's initial WUS transmission power on frequency point two is set to P1, and thereafter the power is increased based on P1.

[0094] For example, in some embodiments, suppose the WUS configuration informs the UE that it can transmit WUS on two frequency points, such as frequency point one and frequency point two. Suppose the UE first transmits WUS on frequency point one with the initial power Pue-tx-init in the aforementioned WUS configuration, and after several power boosts, it reaches P1. At this time, the UE switches to frequency point two to transmit WUS, and the initial WUS transmission power of the UE on frequency point two is set to P1+Pramp.

[0095] For example, in some embodiments, suppose the WUS configuration informs the UE that it can transmit WUS on two frequency points, such as frequency point one and frequency point two. Suppose the UE first transmits WUS on frequency point one with the initial power Pue-tx-init in the aforementioned WUS configuration, and after several power increases, reaches P1. At this point, the UE switches to frequency point two to transmit WUS, and the UE's initial WUS transmission power on frequency point two is reset to Pue-tx-init. Pue-tx-init can be an initial transmission power shared by all frequency points, or it can be an initial transmission power configured independently for each frequency point.
