[0148] In some embodiments, in the power saving state, the terminal can put the MR into the ultra-deepsleep state and turn on the LR to listen for wake-up signals, such as the low-power wake-up signal (LP-WUS). When the LR detects the LP-WUS for the terminal, the terminal turns on the MR and performs normal data transmission and reception. By adopting this method, the power consumption of the MR is greatly reduced, and the power consumption of the LR is very low, thereby obtaining a greater power saving gain.

[0149] In some embodiments, in order to detect LP-WUS normally, the terminal needs to obtain the time and frequency position of the network device transmitting LP-WUS. The terminal can obtain time and frequency synchronization by detecting the synchronization signal, and the synchronization signal can be a reused synchronization signal block (Synchronization Signal Physical Broadcast Channel Block, SSB), or a low-power synchronization signal (Low-Power Synchronization Signal, LP-SS). Among them, the terminal obtains time and frequency synchronization based on SSB and / or LP-SS, and LP-WUS can directly carry the wake-up information.

[0150] Optionally, LP-WUS may use Amplitude Shift Keying (ASK) modulation to carry wake-up information. Among them, On-Off Keying (OOK) is a special case of ASK modulation. Taking OOK as an example, on each OOK symbol, a high-level OOK ON symbol (OOK on chip) may represent bit 1, and a low-level OOK OFF symbol (OOK off chip) may represent bit 0.

[0151] Optionally, the LP-WUS information may be encoded such that each coded bit is mapped to an OOK symbol, such as Manchester coding. For 1 / 2 Manchester coding, the information bit 1 of the LP-WUS may be mapped to 2 coded bits (1, 0), and the information bit 0 may be mapped to 2 coded bits (0, 1). For 1 / 4 Manchester coding, the information bit 1 may be mapped to 4 coded bits (1, 0, 1, 0), and the information bit 0 may be mapped to 4 coded 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, multi-bit information can be represented by carrying different sequences. For example, if there are at most M optional information-carrying sequences on each OOK ON symbol, then theoretically M kinds 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 coding, 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, when the number of candidate sequences on an OOK ON symbol is greater than 2, the terminal can successfully receive the information by detecting the time-domain or frequency-domain sequence carried by the OOK symbol. For example, as Figure 1B to Figure 1C shown, the complete 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] Combined with Figure 1B to Figure 1C, let the complete LP-WUS information set be W, 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 in the OOK ON symbol time period d needs to carry the LP-WUS information W. In addition, the time domain or frequency domain sequence of OOK symbols in other parts of the LP-WUS except time period d can also carry information W. Using this method, for OFDM LR, the time period d before the LP-WUS supports early completion of LP-WUS detection. If the channel state of the terminal is poor, the UE can repeatedly receive the wake-up signal, or receive LP-WUS in the entire LP-WUS time period D, thereby improving the detection performance.

[0158] In some implementations, for a terminal in an idle or inactive state of Radio Resource Control (RRC), different code points of LP WUS may be used to indicate the terminal subgroup to be awakened. For example, for the following two code points: (1) 1 code point corresponds to 1 terminal subgroup; (2) 1 code point corresponds to all terminal subgroups. In addition, the time domain / frequency domain sequence on the LP WUS needs to carry all the information of the LP WUS, and the OFDM LR can obtain all the information of the LP WUS from the OFDM sequence.

[0159] In some implementations, for a terminal in an RRC connected state, when the LP WUS function is applied, a period of wake-up delay is required from receiving the LP WUS to enabling downlink information monitoring. Different SCSs may have different wake-up delay capabilities. When the SCS is set, the wake-up delay after the UE receives the LPWUS is determined by the wake-up delay capability corresponding to the SCS.

[0160] Among them, the SCS of the LP WUS may be different from the SCS of the BWP where the MR works. In addition, considering the CA scenario, the SCS of the MR on each CC may also be different. When the terminal receives the LP WUS and the LP WUS instructs the UE to wake up, the UE needs to wake up and monitor the corresponding downlink channel, and needs to determine how the terminal performs downlink reception, for example, how to determine when the terminal performs downlink signal reception.

[0161] Figure 2 FIG. 1 is an interactive diagram of a method for transmitting downlink information according to an embodiment of the present disclosure. Figure 2 As shown, the embodiment of the present disclosure relates to a method for transmitting downlink information, and the method includes:

[0162] Step S2101 , the terminal 101 sends capability information to the network device 102 .

[0163] In some embodiments, the terminal 101 may report the wake-up delay capability supported by the terminal 101 to the network device 102 through capability information.

[0164] In some embodiments, the capability information includes a mapping relationship between multiple SCSs and different wake-up delays, in which each of the multiple SCSs has a corresponding wake-up delay. The terminal 101 can report the wake-up delay corresponding to each SCS for different SCSs.

[0165] Optionally, the wake-up delay is used to indicate the time required for the terminal to wake up after receiving a wake-up signal, and the wake-up signal indicates the terminal to wake up. The terminal wake-up may refer to the terminal's MR switching from a sleep state to a working state to perform normal downlink information reception, such as monitoring and receiving a physical downlink control channel (PDCCH).

[0166] Optionally, when the MR is in a sleep state, the terminal monitors and receives a wake-up signal through the LR. The sleep state may include different degrees, such as an ultra-deep sleep state.

[0167] In some embodiments, the wake-up delay may be, for example, 0.5 ms, 4 ms, 1 slot, or 2 slots, etc. In the case of different SCSs, the wake-up delay corresponding to the terminal 101 may be different.

[0168] In some embodiments, the LR of the terminal may be an OOK LR, which supports envelope detection and reception of the OOK symbol corresponding to the wake-up signal. Alternatively, the LR of the terminal may be an OFDM LR, which supports detection and reception of a time domain sequence or a frequency domain sequence carried by the OOK symbol corresponding to the wake-up signal, thereby improving link performance. Among them, 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 (Low-Power Wake Up Signal, LP-WUS).

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

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

[0172] The second SCS is determined according to the SCS corresponding to the BWP of the MR. Optionally, when the terminal is not configured with CA, the SCS corresponding to the BWP of the MR is the second SCS. Optionally, when the terminal is configured with CA, since the SCS corresponding to the BWP of the MR is different in different cells of CA, the terminal needs to determine the second SCS in the different SCSs, which can be seen in the description of the following embodiments.

[0173] Optionally, the first SCS is different from the second SCS, and the corresponding wake-up delays are different.

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

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

[0176] In some embodiments, the wake-up signal is LP WUS, and LP WUS can indicate whether to wake up the terminal 101. For example, the wake-up signal is used to instruct the terminal to wake up, that is, to instruct the main transceiver MR of the terminal to switch from a sleep state to a working state; optionally, the wake-up signal indicates to wake up the terminal when carrying the identifier of the terminal 101.

[0177] In some embodiments, when the terminal 101 receives a wake-up signal instructing to wake up the terminal, it can wake up at an appropriate time, such as switching the MR from a sleep state to a working state to perform normal downlink information reception.

[0178] Step S2103: Terminal 101 determines the first delay based on the first SCS and / or the second SCS.

[0179] In the first embodiment, the 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 may be a wake-up delay corresponding to the first SCS, for example, the first delay is a wake-up delay corresponding to the SCS of the LP WUS. The terminal determines, based on the first SCS, that the first delay is a wake-up delay corresponding to the first SCS in the mapping relationship.

[0182] This example is applicable to the embodiment in which the terminal 101 receives the LP WUS based on OFDM LR, but not applicable to the case based on OOKLR (OOK-based LR); wherein, for OOK-LR, the signal can only be detected in the time domain by means of envelope detection, energy detection, etc., but the subcarrier of the signal in the frequency domain cannot be detected. Even if the OOK ON symbol of the LP WUS carries an OFDM sequence, OOK-LR cannot detect it.

[0183] In another example, the terminal 101 determines the first delay according to 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) of the MR. The terminal determines the first delay as the wake-up delay corresponding to the second SCS in the mapping relationship according to the second SCS.

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

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

[0186] The cell in CA may be replaced by a carrier, or a serving cell, or a component carrier.

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

[0188] For example, the second SCS is the SCS corresponding to the primary cell (Primary Cell, PCell) in CA, such as the SCS for MR to activate the downlink BWP on the primary cell. The first delay is the wake-up delay corresponding to the SCS of the primary cell. For another example, the second SCS is the largest SCS among the SCSs corresponding to multiple cells in CA, such as the largest SCS among the SCSs for MR to activate the downlink BWP on multiple service cells in CA. The first delay is the wake-up delay corresponding to the largest SCS. For another example, the second SCS is the smallest SCS among the SCSs corresponding to multiple cells in CA, such as the smallest SCS among the SCSs for MR to activate the downlink BWP on multiple service cells in CA. The first delay is the wake-up delay corresponding to the smallest SCS.

[0189] In another optional example of this example, when the second SCS includes different SCSs corresponding to multiple cells of the MR in CA, the terminal determines the wake-up delay corresponding to each SCS in the mapping relationship among different SCSs according to the different SCSs included in the second SCS; and determines the first delay as the maximum or minimum of the wake-up delays corresponding to 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 wake-up delays corresponding to the SCSs for downlink activation of BWP in multiple cells in CA as the first delay to ensure that the terminal has sufficient time to wake up in different scenarios.

[0191] Alternatively, the first delay is 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 wake-up delays corresponding to the SCSs for downlink activation of BWP in multiple cells in CA as the first delay, so that the terminal wakes up as soon as possible and improves communication efficiency.

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

[0193] In one example, the first delay is the wake-up delay corresponding to the maximum SCS between the first SCS and the second SCS.

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

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

[0196] In this example, when the terminal 101 is configured with CA, the second SCS may be an SCS determined according to the SCSs corresponding to different cells of CA. For example, the second SCS may be the SCS corresponding to the PCell in CA, such as the SCS for downlink activation of BWP by MR on the primary cell. Alternatively, the second SCS may be the largest SCS among the SCSs corresponding to multiple cells in CA, such as the largest SCS among the SCSs for downlink activation of BWP by MR on multiple service cells in CA. Alternatively, the second SCS may be the smallest SCS among the SCSs corresponding to multiple cells in CA, such as the smallest SCS among the SCSs for downlink activation of BWP by MR on multiple service cells in CA.

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

[0198] In another example, the first delay is the wake-up delay corresponding to the minimum SCS between the first SCS and the second SCS.

[0199] In this example, the terminal 101 can determine, based on the first SCS and the second SCS, that the first delay is 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 the terminal 101 is not configured with CA or is configured with CA, the selection method of the second SCS can refer to the description of the above example and will not be repeated here.

[0201] In this embodiment, when determining the first delay process and involving the first SCS, it is applicable to the embodiment in which the terminal 101 receives the LP WUS based on OFDMLR, but not applicable to the case based on OOK LR.

[0202] In a third embodiment, the terminal 101 may 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, the terminal 101 determines the wake-up delay corresponding to the first SCS in the mapping relationship according to the first SCS; and determines the wake-up delay corresponding to the second SCS in the mapping relationship according to the second SCS. Wherein, when the terminal 101 is configured or not configured with CA, the selection of the second SCS can refer to the description of the above embodiment.

[0204] In one example, the terminal determines the first delay as the maximum 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 of the wake-up delay corresponding to the first SCS and the wake-up delay corresponding to the second SCS. In this example, after the terminal 101 determines the wake-up delay corresponding to the first SCS and the wake-up delay corresponding to the second SCS, respectively, it can select the larger or maximum one as the first delay, so that the terminal has sufficient wake-up time.

[0205] In another example, the terminal determines the first delay as the minimum 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 minimum wake-up delay between the wake-up delay corresponding to the first SCS and the wake-up delay corresponding to the second SCS. In this example, after the terminal 101 determines the wake-up delay corresponding to the first SCS and the wake-up delay corresponding to the second SCS, respectively, it can select the smaller or minimum one as the first delay, so that the terminal wakes up as soon as possible and improves communication efficiency.

[0206] In a fourth embodiment, the terminal 101 may determine a plurality of first time delays.

[0207] In this embodiment, the terminal 101 may determine the first delay according to the second SCS. The terminal determines the wake-up delay corresponding to each SCS in the mapping relationship according to the different SCSs included in the second SCS; and determines that the first delay includes the wake-up delay corresponding to each SCS in the different SCSs.

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

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

[0210] Step S2104: Terminal 101 determines a first time point according to the first delay.

[0211] In some embodiments, the first time is 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 been converted 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 and the wake-up signal indicates that the terminal is awake, terminal 101 can execute the wake-up. For example, if MR changes from a sleep state to a working state, terminal 101 can 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 time instant is after an end time instant of the first time delay.

[0214] In this example, the first delay takes the time when the wake-up signal is received as the starting time or starting position, such as the end time position of the wake-up signal as the starting time. During the first delay, the terminal 101 executes or completes the wake-up, and after the end time of the first delay, the terminal 101 can perform normal downlink monitoring through the MR.

[0215] In this example, the first moment may be the first time slot or the first OFDM symbol after the first delay ends. For example, without considering the CA scenario, for the service cell of the MR, the first delay may be the wake-up delay corresponding to the service cell, and the terminal 101 may start monitoring the downlink channel from the first slot after the first delay ends as the starting position; or, the terminal 101 may start monitoring the downlink channel from the first OFDM symbol after the first delay ends as the starting position.

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

[0217] In this example, the first delay takes the time when the wake-up signal is received as the starting time or starting position, such as the end domain position of the wake-up signal as the starting time. Within the first delay, the terminal 101 executes or completes the wake-up, and within the second delay, the terminal can be synchronized. The terminal that has completed the wake-up and synchronization at the first moment can perform normal downlink monitoring through the MR.

[0218] In this example, the second delay may be a synchronization delay defined by the protocol and / or configured by the network device 102. For example, the second delay is determined according to the synchronization signal period T configured by the network device 102 and the number of synchronization signal monitoring times N required by the protocol, for example, the second delay = T*N.

[0219] In this example, the first moment may be the first time slot or the first OFDM symbol after the first delay and the second delay are over, starting from the time when the wake-up signal is received. For example, without considering the CA scenario, for the service cell of the MR, the first delay may be the wake-up delay corresponding to the service cell, and the terminal 101 may start monitoring the downlink channel from the first slot after the end of (the first delay + the second delay) as the starting position; or, the terminal 101 starts monitoring the downlink channel from the first OFDM symbol after the end of (the first delay + the second delay) as the starting position.

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

[0221] In this embodiment, in combination with the description of the foregoing embodiment, the terminal 101 may respectively determine the first delay corresponding to each cell in CA, and further determine the first time 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, the terminal 101 can start monitoring the downlink channel of the cell, such as monitoring PDCCH, from the corresponding first time in each cell. In this embodiment, the first time for starting PDCCH monitoring in each cell in CA can be different, or the first time for some cells to be the same and the first time for some cells to be different.

[0223] Step S2105: The terminal 101 receives downlink control information sent by the network device 102 through the MR starting from the first moment.

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

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

[0249] Figure 4 FIG. 1 is an interactive diagram of a method for transmitting downlink information according to an embodiment of the present disclosure. Figure 4 As shown, the embodiment of the present disclosure relates to a method for transmitting downlink information, and the method includes:

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

[0251] In some embodiments, the DL active BWP in which the LP WUS and the MR work may correspond to different SCSs, and different SCSs correspond to different wake-up delays.

[0252] In some embodiments, when the UE determines the time when the terminal can start downlink channel monitoring according to the SCS, the UE may first determine the wake-up delay based on the SCS.

[0253] Embodiment 1: determining the wake-up delay according to the SCS of the 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 an OFDM signal, and this embodiment is not applicable to OOK-based LR.

[0255] Embodiment 2: The wake-up delay is determined according to the SCS of the DL active BWP in which the MR works.

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

[0257] (1) The wake-up delay is determined according to the SCS of the DL active BWP of the UE's Pcell.

[0258] (2) The wake-up delay is determined according to the smallest SCS among multiple serving cells DL active BWP of the UE.

[0259] (3) The wake-up delay is determined according to the largest SCS among the multiple serving cell DL active BWPs of the UE.

[0260] (4) The wake-up delay is determined according to the maximum wake-up delay among the wake-up delays corresponding to the SCSs of multiple serving cells DL active BWP of the UE.

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

[0262] (6) The wake-up delay of each serving cell of the UE is determined respectively. For example, the wake-up delay 1 of serving cell 1 is determined according to SCS1 of serving cell 1, and the wake-up delay 2 of serving cell 2 is determined according to SCS2 of serving cell 2. In this way, different serving cells determine the wake-up delay of their own serving cells, 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 corresponding to each cell for different cells.

[0264] Embodiment 3: The wake-up delay is determined according to the largest SCS between the SCS of the LP WUS and the SCS of the DL active BWP in which the MR works.

[0265] Embodiment 4: The wake-up delay is determined according to the smallest SCS between the SCS of the LP WUS and the SCS of the DL active BWP in which the MR works.

[0266] Embodiment 5: The wake-up delay is determined according to 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 in which the MR works.

[0267] The wake-up delay determined by the SCS of the DL active BWP in which the MR works is determined according to any solution in the second embodiment.

[0268] Embodiment 6: The wake-up delay is determined according to 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 in which the MR works.

[0269] The wake-up delay determined by the SCS of the DL active BWP in which the MR works is determined according to any solution in the second embodiment.

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

[0271] Step S4102: The UE determines a time to start downlink channel monitoring.

[0272] In some embodiments, after determining the wake-up delay, the UE may determine the time for the UE to start downlink channel monitoring.

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

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

[0275] (1) It may be a moment after the wake-up delay ends, for example, monitoring the downlink channel starts from the starting position of the first slot after the wake-up delay ends on the serving cell; for example, monitoring the downlink channel starts from the starting position of the first OFDM symbol after the wake-up delay ends on the serving cell.

[0276] (2) Channel monitoring may be enabled only after the wake-up delay plus the synchronization delay. For example, downlink channel monitoring may be enabled at the start position of the first slot after the wake-up delay + synchronization delay on the serving cell; for example, downlink channel monitoring may be enabled at the start position of the first OFDM symbol after the wake-up delay + synchronization delay on the serving cell.

[0277] Optionally, the synchronization delay may be defined by the protocol or configured by the base station, for example, determined by the synchronization signal period T configured by the base station and the number of synchronization signal monitoring times N required by the protocol, for example, synchronization delay = T*N.

[0278] In some embodiments, since the SCSs on different serving cells of the UE are different, the boundaries of their time domain units may not be aligned, so the time when PDCCH monitoring can actually start on each serving cell may not be exactly the same.

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

[0280] In some embodiments, reference may be made to the steps and optional implementation methods of other embodiments recorded before or after the description corresponding to this embodiment, as well as other related parts in the description, which will not be repeated here.
