[0065] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0066] I. Low power wake up receiver (LP WUR).

[0067] The basic working principle of the LP WUR is that the receiving end comprises a first module and a second module. The first module is a main communication module, used to receive and send communication data transmitted by the sending end. The second module is a low-power module, used to receive a low-power wake-up signal (LP-WUS) and a low-power synchronization signal (LP-SS) sent by the sending end. The low-power wake-up signal is used to wake up the main communication module of the receiving end. The low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal, for example, for performing radio resource management (RRM) measurement of a serving cell, and can also provide wake-up link management, for example, determining whether to activate or deactivate the LP-WUR and turn off the main receiver (MR) according to the measurement result. When the first module is not woken up by the second module, it is always in a closed state and does not send or receive data. When there is downlink data, the second module detects the wake-up signal sent by the sending end, and the wake-up signal contains terminal information of the terminal, and then the second module triggers the first module to switch from the closed state to the working state to perform data reception and transmission. The second module can be continuously turned on or discontinuously turned on. When the second module is turned on, it can receive the low-power wake-up signal and the low-power synchronization signal.

[0068] II. Low-power wake-up signal

[0069] In this embodiment, the WUS can be a low-power wake-up signal (LP-WUS).

[0070] In order to reduce the receiving activity of the terminal in the standby state, so that the radio frequency (RF) and baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception, a low-power receiver can be introduced into the receiving module of the terminal to achieve this. In one embodiment, this near-zero-power receiver does not require complex signal detection (such as amplification, filtering, quantization, etc.) of the RF module and signal processing of the MODEM, but only relies on passive matching filtering and relatively small-power signal processing.

[0071] In one embodiment, the low-power wake-up signal is typically some simple on-off keying (OOK) signal, so that the receiver can recognize the wake-up announcement through simple energy detection, and then possibly sequence detection and the like. In another embodiment, the low-power wake-up signal can be a Frequency-Shift Keying (FSK) signal, an Orthogonal Frequency Division Multiplexing (OFDM) signal, or a hybrid of OFDM and OOK or FSK. In addition, while the terminal opens the low-power receiver to receive the wake-up signal, the main receiver module can be maintained at a lower power consumption level, so that the power consumption is saved through the reception of the wake-up signal.

[0072] The reception of the low-power wake-up signal can be applied to terminals in a Radio Resource Control (RRC) idle or RRC inactive state, and can also be applied to terminals in an RRC connected state, so as to achieve terminal energy saving.

[0073] III. Connected Discontinuous Reception (C-DRX) on the terminal side in a connected state.

[0074] C-DRX allows the terminal to periodically enter a sleep state and not listen to the Physical Downlink Control Channel (PDCCH), and when listening, to wake up from the sleep state, so as to achieve the purpose of power saving.

[0075] Optionally, the sleep state refers to that the terminal does not monitor PDCCH, and the unmonitored PDCCH is a PDCCH scrambled by a radio network temporary identifier (RNTI) as follows: a cell radio network temporary identifier (C-RNTI), a cancellation indication RNTI (CI-RNTI), a configured scheduling RNTI (CS-RNTI), an interruption RNTI (INT-RNTI), a slot format indicator RNTI (SFI-RNTI), a semi-persistent CSI RNTI (SP-CSI-RNTI), a transmit power control-physical uplink control channel-RNTI (TPC-PUCCH-RNTI), a transmit power control-physical uplink shared channel-RNTI (TPC-PUSCH-RNTI), a transmit power control-sounding reference symbols-RNTI (TPC-SRS-RNTI), an automatic gain control indication RNTI (AI-RNTI), a sidelink RNTI (SL-RNTI), a sidelink configured scheduling RNTI (SL-CS-RNTI), a sidelink semi-persistent scheduling vehicle-RNTI (SL-SPS-V-RNTI), a sidelink configured grant 1 RNTI (SL-CG1-RNTI), a sidelink configured grant 2 RNTI (SL-CG2-RNTI), a sidelink configured grant 3 RNTI (SL-CG3-RNTI), a sidelink configured grant 4 RNTI (SL-CG4-RNTI), a sidelink configured grant 5 RNTI (SL-CG5-RNTI), a sidelink configured grant 6 RNTI (SL-CG6-RNTI), a sidelink configured grant 7 RNTI (SL-CG7-RNTI), a sidelink configured grant 8 RNTI (SL-CG8-RNTI), a sidelink configured grant 9 RNTI (SL-CG9-RNTI), a sidelink configured grant 10 RNTI (SL-CG10-RNTI), a sidelink configured grant 11 RNTI (SL-CG11-RNTI), a sidelink configured grant 12 RNTI (SL-CG12-RNTI), a sidelink configured grant 13 RNTI (SL-CG13-RNTI), a sidelink configured grant 14 RNTI (SL-CG14-RNTI), a sidelink configured grant 15 RNTI (SL-CG15-RNTI), a sidelink configured grant 16 RNTI (SL-CG16-RNTI), a sidelink configured grant 17 RNTI (SL-CG17-RNTI), a sidelink configured grant 18 RNTI (SL-CG18-RNTI), a sidelink configured grant 19 RNTI (SL-CG19-RNTI), a sidelink configured grant 20 RNTI (SL-CG20-RNTI), a sidelink configured grant 21 RNTI (SL-CG21-RNTI), a sidelink configured grant 22 RNTI (SL-CG22-RNTI), a sidelink configured grant 23 RNTI (SL-CG23-RNTI), a sidelink configured grant 24 RNTI (SL-CG24-RNTI), a sidelink configured grant 25 RNTI (SL-CG25-RNTI), a sidelink configured grant 26 RNTI (SL-CG26-RNTI), a sidelink configured grant 27 RNTI (SL-CG27-RNTI), a sidelink configured grant 28 RNTI (SL-CG28-RNTI), a sidelink configured grant 29 RNTI (SL-CG29-RNTI), a sidelink configured grant 30 RNTI (SL-CG30-RNTI), a sidelink configured grant 31 RNTI (SL-CG31-RNTI), a sidelink configured grant 32 RNTI (SL-CG32-RNTI), a sidelink configured grant 33 RNTI (SL-CG33-RNTI), a sidelink configuredSL Semi-Persistent Scheduling V-RNTI) and cell discontinuous transmission / reception-RNTI (cellDTRX-RNTI).

[0076] The wake-up refers to the time when the terminal is "awake" to monitor the PDCCH and the like, and the time when the terminal is awake is collectively referred to as active time (Active Time), which includes the following cases:

[0077] DRX on-duration timer (drx-onDurationTimer): At this time, the UE is monitoring whether there is a PDCCH;

[0078] DRX inactivity timer (drx-InactivityTimer): At this time, the UE has monitored the PDCCH and is receiving downlink data;

[0079] DRX downlink retransmission timer (drx-RetransmissionTimerDL) or DRX uplink retransmission timer (drx-RetransmissionTimerUL): At this time, the terminal is waiting for retransmission;

[0080] Random access contention resolution timer (ra-ContentionResolutionTimer) or message B response window (msgB-ResponseWindow): At this time, the UE is waiting to receive Msg2 or Msg4;

[0081] Scheduling request (SR) is sent on PUCCH: After the terminal sends SR, at this time the UE is waiting for uplink grant (UL grant);

[0082] Non-contention random access terminal receives random access response (Rach access response, RAR): At this time, the UE is waiting to receive downlink control information (Downlink Control Information, DCI) scrambled by C-RNTI, which is used to indicate uplink resource scheduling.

[0083] Four, R17 PDCCH skipping indication (R17 PDCCH skipping indication).

[0084] PDCCH skipping is a method to skip PDCCH monitoring in a time interval by PDCCH skipping related indication in DCI to save energy. For example, skip PDCCH monitoring in the following 4, 8, 16 slots or ms by PDCCH skipping DCI. Skip monitoring means not monitoring. PDCCH skipping can only be applied to PDCCH corresponding to Type3-PDCCH CSS sets or USS sets.

[0085] There are two types of terminal behaviors corresponding to the indication bits of PDCCH skipping indication. One type is all zero, corresponding to the terminal behavior of not performing PDCCH skipping. The other type is non-all zero, corresponding to the terminal behavior of skipping PDCCH(Type3-PDCCH CSS sets or USS sets corresponding PDCCH) monitoring in a specific time interval.

[0086] Five, DRX group (DRX group).

[0087] A terminal can be configured with multiple serving cells, and data transmission is performed in multiple serving cells. For DRX application under CA, the current standard is to specify that a DRX group can include one or more serving cells. In a DRX group, the terminal's DRX onduration and DRX inactivity timer are started and stopped at the same time in the entire DRX group. However, the timer for each HARQ process (per HARQ process) is independently maintained (started, restarted, or stopped) by the HARQ process of each serving cell, including the DRX HARQ RTT timer and the DRX Retransmission Timer.

[0088] The network side device can configure at most two DRX groups for the terminal. When the network side device only configures one DRX group, all serving cells of the terminal belong to the one DRX group. If the network side device configures two DRX groups, the drx-onDurationTimer and the drx-InactivityTimer of the two DRX groups are independently configured respectively. But the remaining DRX related timers are shared by the two DRX groups.

[0089] Currently, the application of LP-WUS monitoring in the connected state CA case is discussed, but the start, stop and recovery of the application of LP-WUS monitoring between multiple serving cells have not been designed.

[0090] The terminal may not have the ability to monitor the PDCCH and monitor the WUS on the same frequency band at the same time. The WUS can control the monitoring of the PDCCH on multiple serving cells, and the R17 PDCCH skipping is used for a single serving cell to control the skipping of the monitoring of the PDCCH. Therefore, if the R17 PDCCH skipping signaling implicitly activates the monitoring of the LP-WUS, the terminal needs to monitor the PDCCH and monitor the WUS at the same time. For example, in CA, the serving cell 1 receives the PDCCH skipping to implicitly activate the monitoring of the WUS, and the serving cell 2 does not receive the PDCCH skipping to continue monitoring the PDCCH. Then the terminal performs WUS monitoring on the serving cell 1 and PDCCH monitoring on the serving cell 2, and the terminal needs to perform low-power monitoring and NR signal monitoring on different frequency bands at the same time. Simultaneous reception of the WUS and the PDCCH may require additional hardware considerations, especially when some radio frequency front-end modules are shared. Therefore, in order to avoid additional constraints on hardware implementation, the corresponding design is made, and the transmission processing method of the present application is proposed.

[0091] The transmission processing method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings, some embodiments and application scenarios.

[0092] Referring to FIG. 2, the transmission processing method provided by the embodiments of the present application includes:

[0093] The terminal performs physical downlink control channel (PDCCH) monitoring on a first serving cell group of the terminal when detecting a wake-up signal (WUS);

[0094] The first serving cell group includes at least one of the following:

[0095] all serving cells of the terminal;

[0096] a serving cell belonging to a same frequency range as a serving cell receiving the WUS;

[0097] a serving cell belonging to a same cell group as a serving cell receiving the WUS.

[0098] In the embodiments of the present application, the terminal can listen to the WUS on the frequency domain resource or the serving cell configured with the WUS listening. In the case that the terminal listens to the WUS and the WUS is used to wake up the terminal, the terminal performs PDCCH listening in the first cell group according to the WUS. Wherein, the terminal listens to the WUS and the WUS is used to wake up the terminal can be understood as that the terminal listens to the WUS associated with the terminal.

[0099] Optionally, the serving cell of the terminal mentioned in the embodiments of the present application can be understood as the serving cell configured and activated by the terminal.

[0100] Optionally, the first serving cell group can include one or at least two serving cells.

[0101] Optionally, the serving cell belonging to a same frequency range as a serving cell receiving the WUS can be understood as the serving cell in a target frequency range, and the target frequency range is the frequency range corresponding to the serving cell receiving the WUS.

[0102] Optionally, the serving cell belonging to a same cell group as a serving cell receiving the WUS can be understood as the serving cell corresponding to a target DRX group, and the serving cell receiving the WUS belongs to the target DRX group.

[0103] Optionally, the PDCCH listening can be understood or replaced as resuming, starting or falling back to the PDCCH listening.

[0104] In the embodiments of the present application, the terminal performs PDCCH listening on the first serving cell group of the terminal in the case that the terminal detects the wake-up signal WUS. The first serving cell group includes at least one of the following: all serving cells of the terminal; a serving cell belonging to a same frequency range as a serving cell receiving the WUS; and a serving cell belonging to a same cell group as a serving cell receiving the WUS. In this way, since the behavior of applying the WUS in different cells is specified, the behavior of multiple serving cells of the terminal can be controlled by one WUS, so as to reduce the power consumption of the terminal for WUS listening. At the same time, since the terminal performs PDCCH listening on the first serving cell group through the WUS, the wake-up control of the terminal in the CA state can be realized, and thus the power consumption of the terminal in the CA state can be reduced.

[0105] Optionally, in some embodiments, the performing PDCCH monitoring comprises:

[0106] starting a PDCCH monitoring timer by the terminal;

[0107] monitoring PDCCH by the terminal during running of the PDCCH monitoring timer.

[0108] In the embodiments of the present application, the PDCCH monitoring timer can be a conventional related timer, such as a DRX onduration timer or a DRX inactivity timer, or the PDCCH monitoring timer is a newly defined timer for PDCCH monitoring triggered by WUS. Optionally, since the time of performing PDCCH monitoring is controlled by the PDCCH monitoring timer, the WUS monitoring can be resumed after the PDCCH monitoring timer expires, so as to further realize the energy saving of the terminal.

[0109] Optionally, the PDCCH monitoring timer is configured for the first serving cell group, that is, the PDCCH monitoring timer performs timer operations on the first serving cell group, including starting, pausing, stopping or resuming behaviors, etc.

[0110] Optionally, in some embodiments, the method further comprises:

[0111] in the case where the PDCCH monitoring timer expires, or in the case where the first indication information is received, performing a target operation by the terminal;

[0112] wherein the target operation comprises at least one of the following: performing WUS monitoring; skipping PDCCH monitoring on a second serving cell group of the terminal;

[0113] wherein the second serving cell group comprises at least one of the following:

[0114] the first serving cell group;

[0115] all serving cells of the terminal;

[0116] a serving cell scheduled by a downlink control information DCI carrying the first indication information;

[0117] a serving cell where the first indication information is received;

[0118] a serving cell configured or supporting the first indication information.

[0119] In an embodiment, the type of the second serving cell is different for the case that the PDCCH monitoring timer expires and for the case that the first indication information is received.

[0120] In an embodiment of the present application, the WUS monitoring can be understood or replaced as the terminal resuming, starting or falling back to the WUS monitoring. For example, in some embodiments, the terminal resumes, starts or falls back to the WUS monitoring in the case that the PDCCH monitoring timer expires. Alternatively, in some embodiments, the terminal monitors the WUS on a specific serving cell or on a specific frequency domain resource in the case that the PDCCH monitoring timer expires. In one case, the frequency domain monitoring location of the WUS is outside the frequency domain resource of the serving cell of the terminal.

[0121] Alternatively, in some embodiments, the second serving cell group can include the serving cell configured with the WUS monitoring.

[0122] Alternatively, the specific frequency domain resource can be understood as the frequency domain resource configured with the WUS monitoring, and the specific serving cell can be understood as the serving cell configured with the WUS monitoring.

[0123] Alternatively, the frequency domain resource of the WUS can be in a serving cell or a non-serving cell. In one case, the cell of the WUS cannot be deactivated or cannot enter a dormant or dormancy state, i.e., cannot be switched to a dormant Bandwidth Part (dormant BWP). Alternatively, the monitoring of the WUS is not affected by the activation or deactivation of the serving cell. Alternatively, the monitoring of the WUS is not affected by the BWP switching of the serving cell or the dormancy state switching of the serving cell.

[0124] It should be understood that, in the case of triggering the target operation based on the expiration of the PDCCH monitoring timer, the second serving cell group can include at least one of the first serving cell group and all serving cells of the terminal. In the case of triggering the target operation based on the first indication information, the second serving cell group can be understood as the serving cell to which the first indication information is applied. The second serving cell group can include at least one of the following: the first serving cell group; all serving cells of the terminal; a serving cell scheduled by a Downlink Control Information (DCI) carrying the first indication information; a serving cell in which the first indication information is received; a serving cell configured or supporting the first indication information. Alternatively, the cell associated with the execution of the target operation can be a serving cell supporting the first indication information.

[0125] Optionally, in some embodiments, the network-side device can configure or indicate the service cells to which the first indication information is applicable, which can be understood or replaced as the service cells supporting the first indication information. For example, the network-side device configures a list of service cells to which the first indication information is applicable. It can be understood that if one or more service cells of the terminal are not in the above-mentioned list of service cells to which the first indication information is applicable or if one or more service cells of the terminal do not support the first indication information, the first indication information will not be applied on these cells, i.e., the target operation will not be performed based on the first indication information. Specifically, the network-side device can send second indication information to the terminal, which is used to indicate the above-mentioned list of service cells.

[0126] In the embodiments of the present application, the terminal is triggered to perform the target operation through the PDCCH monitoring timer or the first indication information, so that the terminal can return to at least one of the behaviors of skipping PDCCH and performing WUS monitoring, thereby further reducing the power consumption of the terminal.

[0127] Optionally, in some embodiments, the receiving of the first indication information comprises receiving the first indication information on at least one service cell of the terminal or on a specific service cell of the terminal.

[0128] In the embodiments of the present application, the above-mentioned specific service cell can be understood as a service cell configured with the first indication information or a service cell indicated by the network-side device. For example, the specific service cell receiving the first indication information is any service cell or a primary service cell, etc.

[0129] Optionally, the WUS monitoring performed by the terminal comprises:

[0130] The terminal performs WUS monitoring on a frequency domain resource or a service cell configured with WUS monitoring.

[0131] In the embodiments of the present application, the terminal performs WUS monitoring on the frequency domain resource or the service cell configured with WUS monitoring, so that the terminal can exit the PDCCH monitoring state after completing the PDCCH monitoring, thereby reducing the power consumption of the terminal.

[0132] Optionally, the above-mentioned frequency domain resource or service cell can be pre-configured by a protocol or a network-side device.

[0133] Optionally, in some embodiments, the WUS monitoring performed by the terminal on the frequency domain resource or the service cell configured with WUS monitoring comprises:

[0134] In a case that the first indication information is received, the terminal performs WUS monitoring on a frequency domain resource or a serving cell on which WUS monitoring is configured, and the first indication information is PDCCH skipping indication information.

[0135] Optionally, the PDCCH skipping indication information can apply the existing PDCCH skipping indication (R17 PDCCH skipping indication) bit. However, the function implemented by the existing R17 PDCCH skipping indication is different. Alternatively, the PDCCH skipping indication information is newly defined PDCCH skipping indication information.

[0136] Among them, the function of the R17 PDCCH skipping indication is at least one of the following extensions or modifications:

[0137] 1) Compared with the existing R17 PDCCH skipping indication acting on one serving cell, the scope of the PDCCH skipping indication mentioned in the embodiment of the present application is extended, for example, acting on all serving cells, that is, skipping PDCCH monitoring on all serving cells.

[0138] 2) Compared with the existing R17 PDCCH skipping indication indicating skipping PDCCH monitoring for a certain duration, the PDCCH skipping indication mentioned in the embodiment of the present application does not limit the duration of skipping PDCCH, or is understood as skipping PDCCH monitoring for an infinite duration, or it is agreed that the terminal ignores the skipping PDCCH duration indicated by the existing R17 PDCCH skipping indication.

[0139] 3) Compared with the existing R17 PDCCH skipping indication only used to indicate the terminal to skip PDCCH monitoring, the PDCCH skipping indication mentioned in the embodiment of the present application extends its function to: used to indicate the terminal to skip PDCCH monitoring and also used to indicate to start WUS monitoring, or used to indicate the terminal to start or resume WUS monitoring after the end of PDCCH skipping duration.

[0140] 4) Further increase the "infinite state" compared to the PDCCH skipping duration values that can be configured by the existing network. In one embodiment, the terminal is in the infinite state when it receives the skip PDCCH monitoring indication on any one serving cell or on the Pcell, then the terminal performs skip or stop PDCCH monitoring on all serving cells and starts LP-WUS monitoring.

[0141] Optionally, in some embodiments, if the first indication information is newly defined indication information, for example, the first indication information is referred to as WUS on, activation or application indication information, the function of the WUS on, activation or application indication information includes at least one of the following: indicating all serving cells to perform skip PDCCH monitoring; indicating the serving cell or frequency resource configured with WUS monitoring to start WUS monitoring. Further, the indication that all serving cells perform skip PDCCH monitoring can be understood as not limiting the duration of skip PDCCH monitoring, or indicating skip PDCCH monitoring for an infinite length.

[0142] Optionally, in some embodiments, the skip PDCCH monitoring duration value indicated in the skip PDCCH monitoring indication information is infinite or a specific state, and the specific state is used to represent that the skip PDCCH monitoring duration is not limited, or the skip PDCCH monitoring indication information does not limit the duration of skip PDCCH monitoring.

[0143] Optionally, in some embodiments, the terminal receives the above-mentioned first indication information on any one serving cell or on the Pcell, and the terminal performs stop or skip PDCCH monitoring on all serving cells and starts WUS monitoring.

[0144] In the embodiments of the present application, the skip PDCCH monitoring indication information can indicate skip PDCCH monitoring for an infinite length of time, that is, in the case where the PDCCH monitoring timer expires, or in the case where the first indication information is received, the terminal is in the state of skip PDCCH monitoring for an infinite length of time. Further, the terminal can terminate skip PDCCH monitoring in the case where it subsequently receives other indication information.

[0145] Optionally, in some embodiments, the WUS monitoring performed by the terminal on the serving cell configured with WUS monitoring includes:

[0146] The terminal skips PDCCH monitoring for a period of time according to the indication of the first indication information on a serving cell configured with WUS monitoring, and performs WUS monitoring at or after the end of the skipping of PDCCH monitoring.

[0147] Optionally, the period of time is not infinite in value.

[0148] In an embodiment, in the case where the PDCCH monitoring timer expires, or in the case where the first indication information is received, the terminal performs skipping of PDCCH monitoring on a serving cell not configured with WUS monitoring until an event triggers or the indication information indicates to return to PDCCH monitoring.

[0149] Optionally, in some embodiments, the starting time of performing WUS monitoring is the end time of the last skipping of PDCCH monitoring in a target serving cell, or the starting time of performing WUS monitoring is after the end time of the last skipping of PDCCH monitoring in the target serving cell, the target serving cell being a serving cell configured with WUS monitoring. For example, the terminal is configured with WUS monitoring on multiple serving cells, and the duration of performing skipping of PDCCH monitoring on the multiple serving cells is different, then the starting time of performing WUS monitoring is based on the end time of the last skipping of PDCCH monitoring on the multiple serving cells.

[0150] In an embodiment of the present application, the network side device can configure different skipping PDCCH monitoring time lengths for different serving cells to which the first indication information is applied, and perform, resume or start WUS monitoring after the end of the longest skipping PDCCH monitoring time on a serving cell configured with WUS monitoring. For example, the target serving cells include cell 1 and cell 2, cell 1 ends skipping PDCCH monitoring at time 1, and cell 2 skips PDCCH monitoring at time 2. If time 1 is before time 2, then WUS monitoring is started at time 2, and time 2 is the starting time of performing WUS monitoring.

[0151] Optionally, the end time of the last skipping of PDCCH monitoring in the target serving cell can be understood as the actual end time of the last skipping of PDCCH monitoring in the target serving cell, or the end time of the time unit in which the actual end time of the last skipping of PDCCH monitoring in the target serving cell is located.

[0152] Optionally, in some embodiments, in the case where the skipping PDCCH monitoring duration indicated by the skipping PDCCH monitoring indication is a specific value, the terminal does not perform WUS monitoring during the skipping PDCCH monitoring duration.

[0153] The specific value is used to indicate that the PDCCH monitoring duration is limited.

[0154] In the embodiments of the present application, the specific value can be understood as a non-infinite duration length.

[0155] It should be understood that if the PDCCH monitoring skipping is not limited in duration, or the duration of the PDCCH monitoring skipping is infinite, the terminal directly performs WUS monitoring after the PDCCH monitoring timer expires or the first indication information is received.

[0156] Optionally, in some embodiments, the method further comprises:

[0157] In the case that the terminal receives the WUS for waking up the terminal after the terminal receives the PDCCH monitoring skipping indication information indicating that the PDCCH monitoring is skipped for a duration, the terminal performs at least one of the following operations:

[0158] skipping the PDCCH monitoring for a duration according to the PDCCH monitoring skipping indication information;

[0159] skipping the PDCCH monitoring for a duration according to the PDCCH monitoring skipping indication information and starting the PDCCH monitoring at the end of the PDCCH monitoring duration;

[0160] ignoring the detected WUS;

[0161] starting the PDCCH monitoring according to the WUS.

[0162] In the embodiments of the present application, another expression is: if the terminal receives the PDCCH monitoring skipping indication information indicating that the PDCCH monitoring is skipped for a duration before receiving the WUS for waking up the terminal, the above operations are performed; or if the terminal receives the WUS for waking up the terminal within the PDCCH monitoring skipping duration indicated by the PDCCH monitoring skipping indication information, the above operations are performed.

[0163] For example, if the terminal receives the PDCCH monitoring skipping indication information indicating skipping PDCCH monitoring for a duration before receiving the WUS for waking up the terminal, the terminal skips PDCCH monitoring for a duration according to the PDCCH monitoring skipping indication and starts PDCCH monitoring if the PDCCH monitoring skipping duration ends; or if the terminal receives the WUS for waking up the terminal within the PDCCH monitoring skipping duration indicated by the PDCCH monitoring skipping indication information, the terminal skips PDCCH monitoring for a duration according to the PDCCH monitoring skipping indication and starts PDCCH monitoring if the PDCCH monitoring skipping duration ends.

[0164] Optionally, in some embodiments, in the case that the PDCCH monitoring timer expires after the terminal receives the PDCCH monitoring skipping indication information indicating skipping PDCCH monitoring for a duration or the terminal receives the first indication information, the terminal performs at least one of the following:

[0165] skipping PDCCH monitoring for a duration according to the PDCCH monitoring skipping indication information;

[0166] skipping PDCCH monitoring for a duration according to the PDCCH monitoring skipping indication information and starting WUS monitoring if the PDCCH monitoring skipping duration ends;

[0167] ignoring the detected first indication information or ignoring the expiration of the PDCCH monitoring timer;

[0168] starting WUS monitoring according to the expiration of the PDCCH monitoring timer or the first indication information.

[0169] In the embodiments of the present application, another expression is as follows: if the PDCCH monitoring timer expires or the terminal receives the first indication information before receiving the WUS for waking up the terminal, the above operations are performed; or if the terminal receives the WUS for waking up the terminal after the PDCCH monitoring timer expires or the terminal receives the first indication information, the above operations are performed.

[0170] For example, if the terminal receives a WUS for waking up the terminal before the PDCCH monitoring timer expires or the terminal receives the first indication information, the terminal skips PDCCH monitoring for a duration according to the skip PDCCH monitoring indication information and starts WUS monitoring at the end of the PDCCH monitoring duration; or if the terminal receives a WUS for waking up the terminal after the PDCCH monitoring timer expires or the terminal receives the first indication information, the terminal skips PDCCH monitoring for a duration according to the skip PDCCH monitoring indication information and starts WUS monitoring at the end of the PDCCH monitoring duration.

[0171] Optionally, in some embodiments, the method further comprises:

[0172] The terminal receives WUS configuration information;

[0173] The terminal detects a WUS based on the WUS configuration information;

[0174] The WUS configuration information satisfies any of the following conditions:

[0175] The WUS configuration information includes at least two sets of WUS configurations, and each WUS configuration corresponds to a frequency range or a discontinuous reception (DRX) group, and the WUS is used to instruct a service cell in the DRX group or the frequency range corresponding to the associated WUS configuration to start PDCCH monitoring;

[0176] The WUS configuration information includes a set of WUS configurations, and the WUS is used to instruct a service cell in at least one DRX group or at least one frequency range to start PDCCH monitoring.

[0177] Further, in the embodiments of the present application, each DRX group or frequency range in the WUS is associated with different indication bits, or each DRX group or frequency range in the WUS corresponds to the same indication bit. That is, the WUS indicates starting PDCCH monitoring for each FR service cell or for each DRX group. Alternatively, all service cells share the same WUS indication. Alternatively, the WUS carries index information of a first service cell group that indicates starting PDCCH monitoring.

[0178] Optionally, in the embodiments of the present application, one or more sets of WUS monitoring configurations can be used. The multiple sets of WUS monitoring configurations can be configured on the same or different cells or frequency domain resources. Different WUS monitoring configurations control or act on different service cells or service cell groups.

[0179] Optionally, in some embodiments, the network side device can configure the PDCCH monitoring timer separately for the terminal in the service cell group of different frequency ranges. For example, the following at least one case can be included:

[0180] The PDCCH monitoring timer is configured for the service cell group of Frequency Range (FR) 1;

[0181] Another PDCCH monitoring timer is configured for the service cell group of FR2.

[0182] In order to better understand the present application, the implementation process of the present application is described below through some examples.

[0183] Embodiment one, as shown in FIG. 3, in an embodiment, the WUS acts on all service cells of the terminal, that is, instructs the terminal to start PDCCH monitoring on its service cells. The method of starting PDCCH monitoring can be based on starting the PDCCH monitoring timer, which is configured to all service cells of the terminal. The terminal monitors PDCCH monitoring on the service cells of the terminal during the running of the timer. In the case where the timer expires, the terminal performs at least one of the following operations: stops or exits PDCCH monitoring on all service cells; starts WUS monitoring on all service cells. As shown in FIG. 3, the network side device configures WUS monitoring on the Pcell, so that in the case where the timer expires, the terminal resumes WUS monitoring on the service cell configured with WUS, and skips PDCCH monitoring on the service cell (such as scell1 and scell2) which is not configured with WUS monitoring.

[0184] Embodiment two, as shown in FIG. 4, in an embodiment, the network side device configures two groups (cell groups or DRX groups) for the terminal. The length of the PDCCH monitoring timer is configured separately for each group. In addition, the WUS is configured to monitor the WUS on two cells in the two groups. The WUS respectively indicates the wake-up of the two groups.

[0185] In another embodiment, in this scenario, the network side device only configures WUS monitoring on one cell in one group, and the WUS respectively carries the WUS indication information of the two groups in the WUS.

[0186] Optionally, the WUS indicates to start PDCCH monitoring of the first serving cell group, wherein the starting time of starting PDCCH monitoring on different serving cells can be the same or different. For example, the WUS is received at time n, serving Cell1 starts to monitor PDCCH at time n1, and cell2 starts to monitor PDCCH at time n2. In some cases, the different reasons can be that the frequency bands of different serving cells are different, and the time delay of starting PDCCH monitoring on different frequency bands by the terminal is different, and the specific reason is not limited.

[0187] Optionally, in some embodiments, the WUS configuration does not support the terminal to apply in the case of multiple FR configured serving cells. For example, the WUS monitoring configuration does not support application in the embodiment described in FIG. 4. For example, the WUS monitoring is only configured and applied on FR1.

[0188] Embodiment three, as shown in FIG. 5, in an embodiment, the WUS acts on all serving cells of the terminal, that is, instructs the terminal to start PDCCH monitoring on its serving cells. Further, the method of skipping PDCCH monitoring or switching from PDCCH monitoring to WUS monitoring can be based on the first indication information, and the indication of the first indication information applies to all serving cells of the terminal. The terminal receives the first indication information on the serving cell, and then performs at least one of the following according to the indication: exits or skips PDCCH monitoring on all serving cells of the terminal; starts WUS monitoring on all serving cells of the terminal. Further, as shown in FIG. 5, the network side device configures WUS monitoring on Pcell, and the terminal receives the first indication information, then the terminal resumes WUS monitoring on the serving cell configured with WUS, and skips PDCCH monitoring on the serving cell (such as scell1 and scell2) without WUS monitoring.

[0189] Embodiment four, as shown in FIG. 6, in an embodiment, the WUS acts on all serving cells of the terminal, that is, instructs the terminal to start PDCCH monitoring on its serving cells, and the method of skipping PDCCH monitoring or switching from PDCCH monitoring to WUS monitoring can be based on the first indication information, and the indication of the first indication information applies to all serving cells of the terminal. The terminal receives the first indication information on the serving cell, and then uniformly skips PDCCH monitoring on all serving cells of the terminal for a period of time according to the indication. Further, as shown in FIG. 6, after the period of time ends, the terminal resumes WUS monitoring on the serving cell configured with WUS, and continues to skip PDCCH monitoring on the serving cell (such as scell1 and scell2) without WUS monitoring.

[0190] In an embodiment of the fifth embodiment, the network-side device configures the WUS monitoring configuration of the terminal on a frequency band independent of other serving cells of the terminal. The terminal needs to switch between WUS monitoring and PDCCH monitoring, and such switching involves the bandwidth switching process of the terminal, which requires the introduction of switching delay.

[0191] It should be noted that in the above embodiments, the terminal can perform PDCCH monitoring and skip PDCCH monitoring on all serving cells synchronously in the case of carrier aggregation (CA) configuration. That is, the terminal can achieve time division multiplexing (TDM) of WUS and PDCCH monitoring in the time domain, reducing the monitoring complexity of the terminal. Since WUS and PDCCH can achieve TDM reception, in an implementation method, the terminal can share a radio frequency front end or part of a physical antenna for receiving WUS and PDCCH, thus reducing the structural difficulty of the terminal device.

[0192] In an embodiment of the sixth embodiment, the PDCCH monitoring timer or the first indication information under the WUS monitoring configuration scheme can support simultaneous configuration of an R17 PDCCH skipping indication.

[0193] In an embodiment, if the UE is simultaneously configured with the PDCCH monitoring timer or the first indication information and the R17 PDCCH skipping indication, the terminal behaves as follows:

[0194] 1) In the case of receiving a WUS indication to wake up the terminal, if the terminal is in a skip PDCCH monitoring period indicated by the skip PDCCH monitoring indication on a certain serving cell, the terminal continues to skip PDCCH monitoring on the serving cell. Further, the terminal starts PDCCH monitoring after the skip PDCCH monitoring period on the cell.

[0195] 2) In the case of receiving a terminal WUS monitoring start indication or meeting a WUS monitoring start condition (for example, the PDCCH monitoring timer expires or the first indication information is received), if the terminal is in a skip PDCCH monitoring period indicated by the skip PDCCH monitoring indication on a certain serving cell, the terminal continues to skip PDCCH monitoring on the serving cell. Further, the terminal starts WUS monitoring after the skip PDCCH monitoring period on the cell.

[0196] It can be understood that in an embodiment, 1) the priority of the WUS trigger start PDCCH monitoring indication or 2) the priority of the WUS monitoring start indication or condition is lower than the priority of the skip PDCCH monitoring indication.

[0197] In another embodiment, if the UE is configured with both PDCCH monitoring timer or first indication information and R17 PDCCH skipping indication, the terminal behaves as follows:

[0198] 1) In the case of receiving WUS indication to wake up the terminal, regardless of whether the terminal is in the skipping PDCCH monitoring time period indicated by the skipping PDCCH monitoring indication on a certain serving cell, the terminal starts, resumes or begins PDCCH monitoring on all serving cells.

[0199] 2) In the case of receiving terminal WUS monitoring indication or meeting WUS monitoring condition, regardless of whether the terminal is in the skipping PDCCH monitoring time period indicated by the skipping PDCCH monitoring indication on a certain serving cell, the terminal starts, resumes or begins WUS monitoring on all serving cells.

[0200] Embodiment seven, for the case of multiple cell groups configured for the terminal, such as the case of multiple FR cell groups or DRX groups, the WUS monitoring configuration scheme.

[0201] Method 1: Multiple WUS monitoring configurations, each WUS configuration is applied to the associated serving cell group. Further, multiple WUSs are configured in different cells or frequency domain resources, or multiple WUSs are configured in the same cell or frequency domain resource. Optionally, the WUS monitoring occasions contained in the multiple WUS configurations are TDM with each other. The terminal only needs to monitor the WUS monitoring occasion of the WUS configuration associated with it on a specific serving cell.

[0202] Method 2: One WUS monitoring configuration, one WUS is applied to multiple serving cell groups. Further, different indication contents can be associated with different serving cell groups in the WUS indication. Or, the same indication content can be used in the WUS indication to control or act on different serving cell groups.

[0203] Optionally, in an embodiment, WUS monitoring is configured for different cell groups. For example, each cell group selects a serving cell for WUS monitoring configuration, and the WUS is applied to the cell group. For example, the network side device configures WUS on different FR bands, and the WUS is applied to the FR cell where it is located. Optionally, the frequency domain resource for WUS monitoring is not limited to the serving cell of the terminal.

[0204] Optionally, in an embodiment, the network-side device only deploys WUS monitoring in a specific frequency band, which is not necessarily the serving cell of the terminal. For example, the terminal can need to monitor WUS in the frequency band where the WUS is located, and after monitoring the WUS, switch to the frequency band of its serving cell to perform corresponding PDCCH monitoring.

[0205] Optionally, in an embodiment, the WUS configuration does not support application in the case where multiple FRs are configured in the serving cell. For example, the WUS monitoring configuration does not support application in the embodiment described in FIG. 4. For example, the WUS monitoring is only configured and applied on FR1. For example, the protocol does not support configuring a cell group and WUS monitoring for the UE in two or more FRs at the same time. For example, the protocol does not support configuring a DRX group and WUS monitoring configuration for the UE in two or more at the same time.

[0206] It should be noted that the terminal skips PDCCH monitoring during WUS monitoring of the serving cell by default; and during the skipping of PDCCH monitoring of the serving cell, the terminal can determine whether to monitor WUS according to the configuration.

[0207] Referring to FIG. 7, the embodiment of the present application further provides a transmission processing method, as shown in FIG. 7, the transmission processing method comprises:
