[0147] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0148] In some implementations, during power-saving mode, the terminal can put the MR (Mobile Receiver) into ultra-deep sleep and enable the LR (Low-Power Wake-Up Signal) to listen for wake-up signals, such as the Low-Power Wake-Up Signal (LP-WUS). When the LR detects the LP-WUS for this terminal, the terminal activates the MR and performs normal data transmission and reception. This method significantly reduces the power consumption of the MR, and the LR's power consumption is also very low, resulting in greater power-saving gains.

[0149] In some implementations, for proper LP-WUS detection, the terminal needs to obtain the time and frequency location of the LP-WUS transmission from the network device. The terminal can achieve time and frequency synchronization by detecting a synchronization signal, which can be a reused synchronization signal block (SSB) or a low-power synchronization signal (LP-SS). The terminal obtains time and frequency synchronization based on the SSB and / or LP-SS, while LP-WUS can directly carry wake-up information.

[0150] Optionally, LP-WUS can use amplitude shift keying (ASK) modulation to carry wake-up information. On-Off Keying (OOK) modulation is a special case of ASK modulation. Taking OOK as an example, each OOK symbol can be represented by a high-level OOK ON symbol (OOK on chip) to represent bit 1, and a low-level OOK OFF symbol (OOK off chip) to represent bit 0.

[0151] Optionally, the LP-WUS information can be encoded such that each encoded bit is mapped to an OOK symbol, for example, Manchester coding. For 1 / 2 Manchester coding, information bit 1 of LP-WUS can be mapped to 2 encoded bits (1, 0), and information bit 0 can be mapped to 2 encoded bits (0, 1). For 1 / 4 Manchester coding, information bit 1 can be mapped to 4 encoded bits (1, 0, 1, 0), and information bit 0 can be mapped to 4 encoded bits (0, 1, 0, 1).

[0152] Optionally, the time-domain or frequency-domain sequence carried by each OOK symbol of LP-WUS (such as each OOK ON symbol) can also carry wake-up information. On each OOK ON symbol, different sequences can be carried to represent multi-bit information. For example, if there are at most M optional sequences for carrying information on each OOK ON symbol, then theoretically M types of information can be carried on this symbol. If corresponding to the number of bits, floor(log2M) bits can be carried.

[0153] Optionally, the LR of the terminal can include two types, such as OOK LR and Orthogonal Frequency Division Multiplexing (OFDM) LR.

[0154] In some embodiments, in OOK modulation, the information can be encoded first, such as Manchester encoding, and then each encoded bit is sequentially mapped to the OOK symbols in the LP-WUS time period D.

[0155] For OOK LR, OOK LR can complete receiving the information only after receiving all OOK symbols in the LP-WUS time period D. Among them, D can be predefined, semi-statically configured or dynamically indicated.

[0156] For OFDM LR, because sequence-based detection has better link performance, the terminal can successfully receive the information by detecting the time-domain or frequency-domain sequence carried by the OOK symbol. When the number of candidate sequences on one OOK ON symbol is greater than 2, only receiving the first part of the entire LP-WUS signal can achieve successful reception of the information. For example, as shown in FIGS. 1B to 1C, the LP-WUS information is carried within a time period of length d in the LP-WUS signal, where d < D, and d can be predefined, semi-statically configured or dynamically indicated. By using this method, OFDM LR can obtain the complete LP-WUS information in advance, so as to start the operation of waking up the MR in advance, or, if the terminal is not awakened, the terminal can quickly return to the power-saving mode of LP-WUR.

[0157] Referring to Figures 1B and 1C, let W be the complete LP-WUS information set, where A can be a part of W, and (W-A) is the remaining part. The time-domain or frequency-domain sequence of OOK symbols superimposed on the OOK ON symbol time period d needs to carry LP-WUS information W. Furthermore, the time-domain or frequency-domain sequence of OOK symbols in other parts of the LP-WUS besides time period d can also carry information W. Using this method, for OFDM LR, the time period d preceding LP-WUS supports early completion of LP-WUS detection. If the channel condition of the terminal is poor, the UE can repeatedly receive the wake-up signal, or receive LP-WUS throughout the entire LP-WUS time period D, thereby improving detection performance.

[0158] In some implementations, for terminals in the Radio Resource Control (RRC) idle or inactive state, different codepoints in LP WUS can be used to indicate the subgroup of terminals to be woken up. For example, there are two types of codepoints: (1) one codepoint corresponds to one terminal group; (2) one codepoint corresponds to all terminal groups. Furthermore, the time-domain / frequency-domain sequence on LP WUS needs to carry all the information of LP WUS, and the OFDM LR can obtain all the information of LP WUS from the OFDM sequence.

[0159] In some implementations, for a terminal in RRC connected state, when it uses the LP WUS function, there is a wake-up delay from receiving the LP WUS to being able to start downlink information listening. Different SCSs may have different wake-up delay capabilities. With an SCS configured, the wake-up delay after the UE receives the LP WUS is determined by the wake-up delay capability corresponding to that SCS.

[0160] The SCS of LP WUS may differ from that of the BWP where MR operates. Furthermore, considering CA scenarios, the SCS of MR may also differ across different CCs. When the terminal receives LP WUS and LP WUS instructs the UE to wake up, the UE needs to wake up and listen to the corresponding downlink channel. This requires determining how the terminal should perform downlink reception, for example, how to determine when the terminal should receive downlink signals.

[0161] Figure 2 is an interactive schematic diagram illustrating a method for transmitting downlink information according to an embodiment of the present disclosure. As shown in Figure 2, this disclosure relates to a method for transmitting downlink information, the method comprising:

[0162] In step S2101, terminal 101 sends capability information to network device 102.

[0163] In some embodiments, terminal 101 can report its supported wake-up latency capabilities to network device 102 through capability information.

[0164] In some embodiments, the capability information includes a mapping relationship between multiple SCSs and different wake-up latencies, where each SCS has a corresponding wake-up latency. The terminal 101 can report the wake-up latency corresponding to each SCS separately.

[0165] Optionally, wake-up delay is used to represent the time required for the terminal to wake up after receiving a wake-up signal that instructs the terminal to wake up. Terminal wake-up can refer to the terminal's MR (Mobile Message) transitioning from a sleep state to an active state to receive normal downlink information, such as listening to and receiving the Physical Downlink Control Channel (PDCCH).

[0166] Optionally, when the MR is in sleep mode, the terminal listens for and receives wake-up signals via the LR. The sleep state can include different degrees, such as ultra-deep sleep.

[0167] In some embodiments, the wake-up latency can be, for example, 0.5ms, 4ms, 1 slot, or 2 slots, etc. The wake-up latency corresponding to terminal 101 can be different for different SCS (Search Server Classes).

[0168] In some embodiments, the terminal's LR can be an OOK LR, supporting envelope detection and reception of the OOK symbol corresponding to the wake-up signal. Alternatively, the terminal's LR can be an OFDM LR, supporting detection and reception of the time-domain or frequency-domain sequence carried by the OOK symbol corresponding to the wake-up signal, thereby improving link performance. However, the link performance of the OOK LR is weaker than that of the OFDM LR.

[0169] In some embodiments, the wake-up signal may be a low-power wake-up signal (LP-WUS).

[0170] In some embodiments, the plurality of SCSs includes a first SCS and / or a second SCS. For example, terminal 101 reports the wake-up latency corresponding to the first SCS and the wake-up latency corresponding to the second SCS through capability information.

[0171] Here, the first SCS is the SCS corresponding to the wake-up signal. Optionally, the first SCS can be the SCS of LP-WUS.

[0172] The second SCS is determined based on the SCS corresponding to the BWP used for MR. Optionally, when the terminal is not configured with CA, the SCS corresponding to the BWP used for MR is the second SCS. Optionally, when the terminal is configured with CA, since the SCS corresponding to the BWP used for MR is different in different cells of CA, the terminal needs to determine the second SCS from these different SCS, as detailed in the following embodiments.

[0173] Optionally, the first SCS and the second SCS are different, and the wake-up latency corresponding to them is different.

[0174] In some embodiments, network device 102 receives capability information sent by terminal 101.

[0175] In step S2102, network device 102 sends a wake-up signal to terminal 101.

[0176] In some embodiments, the wake-up signal is, for example, LP WUS, which can indicate whether to wake up the terminal 101. For example, the wake-up signal is used to indicate that the terminal is to wake up, that is, to indicate that the terminal's main transceiver MR changes from a sleep state to an operating state; optionally, the wake-up signal indicates that the terminal is to be woken up when it carries the identifier of the terminal 101.

[0177] In some embodiments, when terminal 101 receives a wake-up signal indicating that it should wake up, it can wake up the terminal at an appropriate time, such as changing the MR from a sleep state to a working state to receive downlink information normally.

[0178] In step S2103, terminal 101 determines the first delay based on the first SCS and / or the second SCS.

[0179] In a first embodiment, terminal 101 may determine the first delay based on one of the first SCS and the second SCS.

[0180] In one example, terminal 101 determines a first delay based on a first SCS.

[0181] In this example, the first delay can be the wake-up delay corresponding to the first SCS, for example, the first delay is the wake-up delay corresponding to the SCS of LP WUS. Specifically, the terminal determines the first delay as the wake-up delay corresponding to the first SCS in the mapping relationship based on the first SCS.

[0182] This example applies to the implementation of terminal 101 receiving LP WUS based on OFDM LR, but not to the case based on OOK LR (OOK-based LR). OOK-LR can only detect signals in the time domain through envelope detection, energy detection, etc., but cannot detect subcarriers of the signal in the frequency domain. Even if the OOK ON symbol of LP WUS carries an OFDM sequence, OOK-LR cannot detect it.

[0183] In another example, terminal 101 determines the first delay based on the second SCS. In this example, the first delay is the wake-up delay corresponding to the second SCS, for example, the first delay is the SCS of the downlink active BWP (DL active BWP) operating in MR mode. Specifically, the terminal determines the first delay based on the second SCS as the wake-up delay corresponding to the second SCS in the mapping relationship.

[0184] In an alternative example of this example, if terminal 101 is not configured with CA, the second SCS, such as the SCS of the downlink active BWP that is working with MR, can refer to the SCS of the current serving cell, and the first delay is the wake-up delay corresponding to that SCS.

[0185] In another alternative example of this example, if terminal 101 is configured with CA and the SCS corresponding to different cells in CA is different, such as the downlink activation BWP SCS of MR being different in different cells, terminal 101 can determine an SCS as the second SCS in the SCS of different cells.

[0186] In CA, the cell can be replaced by a carrier, or a serving cell, or a member carrier.

[0187] In this alternative example, the second SCS is determined based on the SCS corresponding to the MR in one or more cells in the CA.

[0188] For example, the second SCS is the SCS corresponding to the primary cell (PCell) in the CA, such as the SCS of the downlink activated BWP on the primary cell by the MR. Then the first delay is the wake-up delay corresponding to the primary cell's SCS. As another example, the second SCS is the largest among the SCSs corresponding to multiple cells in the CA, such as the largest among the SCSs of the downlink activated BWP on multiple serving cells in the CA by the MR. Then the first delay is the wake-up delay corresponding to this largest SCS. Yet another example, the second SCS is the smallest among the SCSs corresponding to multiple cells in the CA, such as the smallest among the SCSs of the downlink activated BWP on multiple serving cells in the CA by the MR. Then the first delay is the wake-up delay corresponding to this smallest SCS.

[0189] In another alternative example of this example, when the second SCS includes different SCSs corresponding to multiple cells in the CA, the terminal determines the wake-up delay corresponding to each SCS in the mapping relationship based on the different SCSs included in the second SCS; and determines the first delay as the maximum or minimum wake-up delay among the different SCSs.

[0190] Optionally, the first delay is the maximum wake-up delay among the wake-up delays corresponding to different SCSs. For example, the terminal uses the maximum wake-up delay among the SCSs corresponding to downlink activation of the BWP in multiple cells in the CA as the first delay to ensure that the terminal has sufficient time to wake up in different scenarios.

[0191] Alternatively, the first delay can be the minimum wake-up delay among the wake-up delays corresponding to different SCSs. For example, the terminal uses the minimum wake-up delay among the SCSs that activate the BWP in multiple cells in the CA as the first delay to enable the terminal to wake up as quickly as possible and improve communication efficiency.

[0192] In the second embodiment, terminal 101 can determine the first delay based on the first SCS and the second SCS.

[0193] In one example, the first latency is the wake-up latency corresponding to the largest SCS among the first SCS and the second SCS.

[0194] In this example, terminal 101 determines the first delay as the wake-up delay corresponding to the largest or larger of the first SCS and the second SCS in the mapping relationship, and uses the wake-up delay corresponding to the SCS as the first delay.

[0195] In this example, when terminal 101 is not configured with CA, the second SCS, such as the SCS of the downlink active BWP that is working with MR, can refer to the SCS of the current serving cell. Terminal 101 selects the larger SCS between the second SCS and the first SCS, and then determines the first delay.

[0196] In this example, when terminal 101 is configured with a CA, the second SCS can be an SCS determined based on the SCS corresponding to different cells in the CA. For example, the second SCS can be the SCS corresponding to the PCell in the CA, such as the SCS of the downlink activated BWP of the MR on the primary cell. Alternatively, the second SCS can be the largest SCS among the SCS corresponding to multiple cells in the CA, such as the largest SCS among the SCS of the downlink activated BWP of the MR on multiple serving cells in the CA. Or, the second SCS can be the smallest SCS among the SCS corresponding to multiple cells in the CA, such as the smallest SCS among the SCS of the downlink activated BWP of the MR on multiple serving cells in the CA.

[0197] Therefore, terminal 101 can determine the wake-up delay corresponding to the larger or largest SCS as the first delay based on the first SCS and the second SCS.

[0198] In another example, the first latency is the wake-up latency corresponding to the smallest SCS among the first SCS and the second SCS.

[0199] In this example, terminal 101 can determine the first delay as the wake-up delay corresponding to the smallest of the first SCS and the second SCS in the mapping relationship, and thus use the wake-up delay corresponding to the SCS as the first delay.

[0200] In this example, when terminal 101 is not configured with CA or is configured with CA, the method for selecting the second SCS can be found in the description of the example above, and will not be repeated here.

[0201] In this embodiment, when determining the first delay, the first SCS is involved, which is applicable to the embodiment where terminal 101 receives LP WUS based on OFDM LR, but not to the case based on OOK LR.

[0202] In the third embodiment, terminal 101 can determine the first delay based on the wake-up delay corresponding to the first SCS and the wake-up delay corresponding to the second SCS.

[0203] In this embodiment, terminal 101 determines the wake-up latency corresponding to the first SCS in the mapping relationship based on the first SCS; and determines the wake-up latency corresponding to the second SCS in the mapping relationship based on the second SCS. The selection of the second SCS, whether terminal 101 is configured with a CA or not, can be referred to the description in the foregoing embodiments.

[0204] In one example, the terminal determines the first delay as the greater of the wake-up delay corresponding to the first SCS and the wake-up delay corresponding to the second SCS. For example, the first delay is the maximum wake-up delay between the first SCS and the second SCS. In this example, after determining the wake-up delay corresponding to the first SCS and the second SCS respectively, the terminal 101 can select the larger or the largest one as the first delay, thus allowing the terminal sufficient wake-up time.

[0205] In another example, the terminal determines the first delay as the minimum wake-up delay between the first SCS and the second SCS. For example, the first delay is the minimum wake-up delay between the first SCS and the second SCS. In this example, after determining the wake-up delays for the first SCS and the second SCS respectively, the terminal 101 can select the smaller or minimum one as the first delay, thereby enabling the terminal to wake up as quickly as possible and improving communication efficiency.

[0206] In the fourth embodiment, terminal 101 can determine multiple first delays.

[0207] In this embodiment, terminal 101 can determine the first delay based on the second SCS. The terminal determines the wake-up delay corresponding to each SCS in the mapping relationship based on the different SCS included in the second SCS; the first delay includes the wake-up delay corresponding to each SCS in the different SCS.

[0208] In this embodiment, in a CA scenario, if the second SCS includes different SCSs corresponding to multiple cells of the MR in the CA, the first latency includes the wake-up latency corresponding to each SCS. Specifically, in this embodiment, the terminal determines the SCS corresponding to the BWP of the MR in each CA cell, thereby determining the first latency corresponding to each CA cell.

[0209] For example, terminal 101 determines the first delay (wake-up delay 1) of MR in cell 1 (serving cell 1) based on SCS1 of cell 1 in CA, and determines the first delay (wake-up delay 2) of MR in cell 2 (serving cell 2) based on SCS2 of cell 2. In this way, the wake-up delay corresponding to each cell can be determined separately, and the wake-up delay corresponding to different cells may be different.

[0210] In step S2104, terminal 101 determines the first moment based on the first time delay.

[0211] In some embodiments, the first moment is located after the terminal 101 receives the wake-up signal, and is used to indicate the time when the terminal 101 completes the wake-up, that is, the MR has changed from the sleep state to the working state and can receive downlink information.

[0212] In some embodiments, when terminal 101 receives a wake-up signal that indicates that the terminal is to wake up, terminal 101 may perform a wake-up, such as when MR changes from a sleep state to a working state, terminal 101 may complete the wake-up within a first delay or within a time range determined based on the first delay.

[0213] In one example, the first moment is after the end of the first time delay.

[0214] In this example, the first delay is defined as the time when the wake-up signal is received, or the time when the wake-up signal ends. Within the first delay, terminal 101 executes or completes the wake-up process. After the end of the first delay, terminal 101 can perform normal downlink listening via MR.

[0215] In this example, the first moment can be the first time slot or the first OFDM symbol after the end of the first delay. For example, without considering the CA scenario, for the serving cell of MR, the first delay can be the wake-up delay corresponding to the serving cell. Terminal 101 can start listening to the downlink channel with the first slot after the end of the first delay as the starting position; or, terminal 101 can start listening to the downlink channel with the first OFDM symbol after the end of the first delay as the starting position.

[0216] In another example, the first moment is after the end of the first delay, and the first moment is at least separated from the end of the first delay by a second delay, which is the delay for the terminal to obtain synchronization.

[0217] In this example, the first delay is defined as the time when the wake-up signal is received, or the time when the wake-up signal ends. Within the first delay, terminal 101 executes or completes wake-up. Within the second delay, the terminal can synchronize. Terminals that have completed wake-up and synchronization in the first delay can perform normal downlink listening via MR.

[0218] In this example, the second delay can be a synchronization delay defined by the protocol and / or configured by network device 102. For example, the second delay is determined based on the synchronization signal period T configured by network device 102 and the number of times the synchronization signal is monitored N as required by the protocol; for example, the second delay = T*N.

[0219] In this example, the first moment can be the time when the wake-up signal is received, starting from the first slot or the first OFDM symbol after both the first and second delays have ended. For example, disregarding the CA scenario, for the serving cell of MR, the first delay can be the wake-up delay corresponding to that serving cell. Terminal 101 can start listening to the downlink channel starting from the first slot after (the first delay + the second delay) ends; or, terminal 101 can start listening to the downlink channel starting from the first OFDM symbol after (the first delay + the second delay) ends.

[0220] In some embodiments, when a CA is configured, such as when a terminal is configured with a CA, each cell in the CA has a corresponding first time.

[0221] In this embodiment, in conjunction with the description of the foregoing embodiments, the terminal 101 can determine the first delay corresponding to each cell in CA, and further determine the first time point corresponding to each cell based on the first delay.

[0222] In this embodiment, in the CA scenario, different cells have different SCSs, and the boundaries of the time-domain units corresponding to different SCSs may not be aligned. After determining the first time corresponding to each cell, terminal 101 can start listening to the downlink channel of each cell, such as listening to the PDCCH, starting at the corresponding first time. In this embodiment, the first time to start PDCCH listening in each cell in CA may be different, or some cells may be the same while others may be different.

[0223] In step S2105, terminal 101 receives downlink control information sent by network device 102 via MR starting from the first moment.

[0224] In some embodiments, network device 102 may send downlink control information, such as PDCCH, immediately after sending a wake-up signal.

[0225] Optionally, network device 102 may start sending PDCCH from the first moment.

[0250] Step S4101: The UE determines the wake-up delay (corresponding to the first delay in the aforementioned embodiment).

[0253] Example 1: Determine the wake-up latency based on the SCS of LP WUS.

[0254] For example, the wake-up delay is the wake-up delay corresponding to the SCS of the LP WUS. For OOK-based LR, the LP WUS may not be transmitted in the frequency domain using OFDM signaling, so this embodiment is not applicable to OOK-based LR.

[0255] Example 2: Determine the wake-up latency based on the SCS of the DL active BWP operated by the MR.

[0256] When the UE is configured with CA, the SCS of the DL active BWP on different carriers may be different. In this case, the following solution can be adopted:

[0257] (1) Determine the wake-up delay based on the SCS of the DL active BWP of the UE's Pcell.

[0258] (2) The wake-up delay is determined based on the minimum SCS among the multiple serving cell DL active BWPs of the UE.

[0259] (3) Determine the wake-up delay based on the largest SCS among the multiple serving cell DL active BWPs of the UE.

[0260] (4) The wake-up delay is determined based on the largest wake-up delay among the wake-up delays corresponding to the SCS of the multiple serving cells DL active BWP of the UE.

[0261] (5) The wake-up delay is determined based on the minimum wake-up delay among the wake-up delays corresponding to the SCS of the multiple serving cells DL active BWP of the UE.

[0262] (6) Determine the wake-up delay of each of the UE's multiple serving cells. For example, determine the wake-up delay 1 of serving cell 1 based on SCS1 of serving cell 1, and determine the wake-up delay 2 of serving cell 2 based on SCS2 of serving cell 2. In this way, each serving cell determines its own wake-up delay, and the wake-up delays of different serving cells may be different.

[0263] Among them, (1) to (5) can determine a unified wake-up delay, and (6) can determine the wake-up delay of each cell for different cells.

[0264] Example 3: The wake-up latency is determined based on the larger SCS between the LP WUS and the DL active BWP operated by MR.

[0265] Example 4: The wake-up latency is determined based on the minimum SCS between the LP WUS and the DL active BWP operated by MR.

[0266] Example 5: The wake-up delay is determined based on the maximum wake-up delay between the wake-up delay corresponding to the SCS of the LP WUS and the wake-up delay determined by the SCS of the DL active BWP operated by the MR.

[0267] The wake-up latency determined by the SCS of the DL active BWP used by MR is determined according to any of the schemes in Embodiment 2 above.

[0268] Example 6: The wake-up delay is determined based on the minimum wake-up delay between the wake-up delay corresponding to the SCS of the LP WUS and the wake-up delay determined by the SCS of the DL active BWP operated by the MR.

[0269] The wake-up latency determined by the SCS of the DL active BWP used by MR is determined according to any of the schemes in Embodiment 2 above.

[0270] It is worth noting that embodiments involving determining wake-up delay based on the SCS of LP WUS may not be applicable to OOK-based LR UEs. These UEs do not process LP WUS reception based on the SCS, but instead receive OOK-based LP WUS signals using envelope detection and energy detection.

[0271] Step S4102: The UE determines the time to start downlink channel listening.

[0272] In some embodiments, after determining the wake-up delay, the UE can determine the time when the UE starts listening to the downlink channel.

[0273] In some embodiments, the UE can start downlink channel listening after the wake-up delay duration is elapsed, starting from the start position of the wake-up delay timing.

[0274] In some embodiments, the terminal may enable downlink channel listening in the following two ways:

[0275] (1) It can be the time after the wake-up delay ends, for example, starting to listen to the downlink channel at the beginning of the first slot after the wake-up delay ends on the serving cell; for example, starting to listen to the downlink channel at the beginning of the first OFDM symbol after the wake-up delay ends on the serving cell.

[0276] (2) Channel listening can be initiated only after the wake-up delay plus the synchronization delay. For example, listening to the downlink channel can begin at the beginning of the first slot after the wake-up delay + synchronization delay ends on the serving cell; or listening to the downlink channel can begin at the beginning of the first OFDM symbol after the wake-up delay + synchronization delay ends on the serving cell.

[0277] Optionally, the aforementioned synchronization delay can be defined by the protocol or configured by the base station. For example, it can be determined jointly based on the synchronization signal period T configured by the base station and the number of times the synchronization signal is monitored N as required by the protocol, such as synchronization delay = T*N.

[0278] In some embodiments, since the SCS on different serving cells of the UE are different, the boundaries of their time domain units may not be aligned, and therefore the actual time when PDCCH listening can start on each serving cell may not be exactly the same.

[0279] Step S4103: The UE listens to the downlink channel.

[0280] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
