[0044] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0045] Terminal energy saving based on PDCCH

[0046] The evolution of communication protocols (e.g., 5G communication protocols) places higher demands on energy conservation in terminal devices. To meet these energy conservation requirements, the discontinuous reception (DRX) mechanism has been introduced.

[0047] Referring to Figure 2, the DRX mechanism includes configuring a DRX cycle for a terminal in a radio resource control (RRC) connection state. A DRX cycle consists of a "DRX on duration" also known as a "DRX duration" and a "DRX inactive period (opportunity for DRX)". During the DRX duration, the terminal device needs to monitor and receive downlink channels (e.g., physical downlink control channel (PDCCH)) and signals. During the DRX inactive period, the terminal device may not receive downlink channels (e.g., PDCCH) or signals to reduce power consumption.

[0048] However, the power savings achieved by the DRX mechanism for terminal devices is still limited. For most terminal devices, there may be no need to receive data transmission for a long period of time (for example, one or more DRX cycles), and they still need to maintain a regular wake-up mechanism to monitor possible downlink transmissions. For such terminal devices, there is room for further energy saving optimization. In the 3GPP Release 16 standard, energy saving signals are introduced for terminal devices in the RRC_CONNECTED state.

[0049] The energy-saving signal can be used in conjunction with the DRX mechanism. Referring to Figure 3, the terminal device receives the energy-saving signal before the DRX period, and determines whether it is in the awake state during the corresponding DRX period based on the indication of the energy-saving signal. When the terminal device has data transmission in a DRX cycle, the energy-saving signal can "wake up" the terminal device so that the terminal device can monitor the PDCCH during the DRX period. Otherwise, when the terminal has no data transmission in a DRX cycle, the energy-saving signal may not "wake up" the terminal device. Accordingly, the terminal device does not need to monitor the PDCCH during the DRX period and is in a sleep state.

[0050] In some implementations, the energy-saving signal may be carried on the PDCCH, and specifically may be carried through downlink control information (DCI) format 2_6.

[0051] Paging process

[0052] The 3GPP R17 standard optimizes energy saving in the process of receiving paging messages by terminal devices in the RRC idle state / inactive state, and introduces information with similar functions to energy-saving signals, namely, paging early indication (PEI).

[0053] If the terminal device receives paging messages in DRX mode, that is, there is a paging occasion (PO) within a DRX cycle, the terminal device only receives paging messages during the PO and does not receive paging messages outside the PO to achieve the purpose of saving power.

[0054] Typically, before receiving a paging message, a terminal device needs to first receive paging parameters through a system message, and calculate the frame number and PO of the paging frame (PF) where the paging message is located in combination with its own UE_ID. Then, within the PO on the PF, the terminal device listens to the PDCCH encrypted by the P-RNTI to receive the paging indication information, and finally receives the paging message based on the paging indication information. In other words, PF indicates the system frame number on which the paging message should appear, and PO indicates the time when it may appear.

[0055] Figure 5 illustrates the location of the PF and the PO within the DRX cycle. As shown in Figure 5, the PF is located within the DRX cycle (or paging cycle). A PF may include one or more POs, and these multiple POs may correspond to different terminals. However, for a terminal device, during the DRX cycle (or paging cycle), the terminal device only needs to monitor its own PO.

[0056] In practice, the probability of a terminal device being paged may not be high, but the terminal device still needs to periodically detect the PDCCH at the corresponding Point of View (PO), resulting in high power consumption. To address this issue, the 3GPP Release 17 standard introduced the PEI (Powered by Information Interference Index) (see Figure 5). The PEI is used to indicate whether the terminal device has received the paging PDCCH at the target Point of View (PO) before the target Point of View (PO) arrives. In some implementations, the PEI can be carried on the PDCCH channel, specifically via DCI format 2_7.

[0057] In addition, the R17 standard further enhances energy conservation for RRC_CONNECTED state terminals, introduces an enhanced solution for search space set group switching introduced in R16, and includes a PDCCH skipping solution that enables energy conservation by skipping PDCCH detection when necessary. Control information related to search space set group switching and PDCCH skipping can also be carried on the PDCCH.

[0058] Terminal energy saving based on wake-up receiver

[0059] In order to further save energy in terminal devices, the 3GPP R18 standard considers introducing a wake-up receiver (WUR) (also known as the "first receiver") to receive the wake-up signal. The wake-up receiver has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption, and it mainly receives the wake-up signal through an envelope detection-based method. Therefore, the wake-up signal (WUS) received by the wake-up receiver is different from the modulation method and waveform of the signal based on the PDCCH carried by the existing 3GPP R16 and R17 standards. The wake-up signal is mainly an envelope signal that ASK modulates the carrier signal. The demodulation of the envelope signal is also mainly based on the energy provided by the wireless radio frequency signal to drive the low-power circuit. Therefore, the WUR can be passive. Of course, the wake-up receiver can also be powered by the terminal device. Regardless of the power supply method, the WUR greatly reduces the power consumption compared to the traditional receiver of the terminal device (also known as the main receiver, or the second receiver).

[0060] FIG6 is a schematic diagram of a terminal device based on a wake-up receiver. Referring to FIG6 , the wake-up receiver 610 can receive a wake-up signal. If the wake-up signal indicates that the main receiver 620 needs to be woken up, the terminal device wakes up (or turns on) the main receiver 620. Otherwise, the main receiver of the terminal device may be in a turned-off state.

[0061] In addition, the wake-up receiver 610 does not need to be turned on and off to save power like a traditional receiver, but can be activated by the WUS at any time and receive the wake-up information in the WUS. The wake-up signal is mainly an envelope signal that performs ASK modulation on the carrier signal. For example, the WUS signal used in the 802.11 technology uses on-off keying (On-Off Keying). The modulation principle of OOK is to modulate the amplitude of the carrier signal to non-zero values ​​and zero values, corresponding to On and Off, respectively, to represent the information bit. OOK is also known as binary amplitude keying (2ASK). As shown in Figure 7, bit 1 can be modulated to "On", and correspondingly, bit 0 can be modulated to "Off".

[0062] It should be noted that the wake-up receiver can be combined with the terminal device as an additional module of the terminal device receiver, or can be used alone as a wake-up function module of a terminal device.

[0063] PDCCH detection

[0064] The transmission resources of PDCCH can be defined and configured through the search space and the control resource set (CORESET). The network device can use the PDCCH search space to instruct the terminal device to detect PDCCH on the corresponding time-frequency resources. Generally, the PDCCH search space can be notified to the terminal device by the network device through RRC signaling. The configuration information of the search space includes the following information:

[0065] -Search space ID: search space index;

[0066] - Control resource set identifier (controlResourceSetId), used to indicate the ID of the CORESET configuration and configure the time-frequency resources of the PDCCH search space;

[0067] -The period of the monitored slot and the offset within the period. Currently, NR supports periods of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 160, 320, 640, 1280, and 2560 time slots.

[0068] - Duration, indicating the number of time slots to be continuously monitored within the PDCCH search space period;

[0069] - monitoringSymbolsWithinSlot, used to indicate the position of the first symbol of the CORESET monitored within the PDCCH monitoring time slot;

[0070] -PDCCH candidates, used to indicate the configuration information of PDCCH candidates;

[0071] -Search space type: indicates whether the PDCCH search space is a common search space or a UE-specific search space;

[0072] The time domain configuration information of the search space may include a detection period, a slot offset, a number of slots, and a symbol position within a slot. Referring to Figure 8 , assuming a detection period of 10 slots, a slot offset of 5 slots, and a number of slots of two, the CORESET corresponding to the control resource set index contains two symbols. The terminal device may monitor the symbol sets of the two CORESETs within the monitoring slot, and the first symbol positions in the symbol sets of the two CORESETs are symbols 0 and 7 within the slot, respectively.

[0073] In NR, the configuration of the PDCCH search space includes CORESET, which indicates the number of RBs occupied by the PDCCH in the frequency domain and the number of OFDM symbols occupied in the time domain. As an example, the configuration information of CORESET given in the RRC configuration information may include the following information:

[0074] - Control Resource Set Id: indicates the CORESET number, which can range from 1 to 11, where CORESET 0 can be the CORESET indicated in the broadcast message;

[0075] - Frequency Domain Resources (frequencyDomainResources): represents the CORESET frequency domain resources, used to indicate the RBs contained in the CORESET;

[0076] -Duration: indicates the number of consecutive CORESET symbols, and the value range is {1, 2, 3};

[0077] -CCE to REG mapping type (cce-REG-MappingType): can be configured as interleaved mapping or non-interleaved mapping;

[0078] - Precoder Granularity: used to indicate whether the precoding granularity of the demodulation reference signal (DMRS) is wideband precoding or narrowband precoding.

[0079] Bandwidth part (BWP)

[0080] Taking NR technology as an example, a BWP is defined as a collection of contiguous resource blocks within the carrier bandwidth. BWP is designed to prevent terminal devices from always operating within the entire carrier bandwidth, especially low-end terminals (or low-capability terminals) that support limited bandwidth and cannot operate on wideband. The introduction of BWP can support more flexible operating bandwidth and reduce terminal device complexity and power consumption.

[0081] In some implementations, the network device can configure up to four uplink BWPs and up to four downlink BWPs for a terminal device in the RRC_CONNECTED state. However, a terminal device can typically have one active downlink BWP and one active uplink BWP at a time. The active BWP is used by the terminal device to transmit data on that BWP.

[0082] In other implementations, the active BWP may be switched between different BWPs. On each downlink BWP, each terminal device may be configured with multiple CORESTs (eg, 3 CORESTs) and multiple search spaces (eg, 10 search spaces).

[0083] As mentioned above, to reduce the power consumption of terminal devices, the network device will send a wake-up signal to the terminal device. Accordingly, when the first receiver (i.e., WUR) of the terminal device receives the wake-up signal, it can wake up the second receiver (i.e., the main receiver) to communicate with the network device. However, there is currently no clear regulation on how the terminal device should wake up the second receiver after receiving the wake-up signal.

[0084] The wireless communication method according to an embodiment of the present application is described below with reference to Figure 9. The method shown in Figure 9 may include steps S910 to S920.

[0085] In step S910, the network device sends a wake-up signal to the terminal device.

[0086] It should be noted that, in addition to the above-described transmission method, the above-mentioned wake-up signal can also be sent using other transmission methods specified in future communication systems. Of course, the above-mentioned wake-up signal can also be sent by other devices (for example, other terminal devices), and this embodiment of the application does not limit this.

[0087] In step S920 , if the first receiver of the terminal device receives a wake-up signal, the terminal device determines first information, where the first information is used to wake up the second receiver of the terminal device.

[0088] The first information may be used to indicate a method for waking up the second receiver. In some implementations, the first information may include second information indicating the wake-up time of the second receiver. In other implementations, the first information may include third information indicating the operating frequency domain of the terminal device after waking up. Of course, the first information may also include both the second and third information, which is not limited in this embodiment of the present application.

[0089] In an embodiment of the present application, after the first receiver receives the wake-up signal, the terminal device can determine the first information used to wake up the second receiver, so that the terminal device can subsequently wake up the second receiver based on the first information, which helps to apply the above-mentioned wake-up signal-based wake-up mechanism to actual communication.

[0090] For ease of understanding, the following describes, in conjunction with Example 1 and Example 2, a solution in which the first information includes the second information and a solution in which the first information includes the third information, respectively.

[0091] Example 1: The first information may include the second information.

[0092] As described above, the second information indicates the wake-up time of the second receiver, wherein the wake-up time may include one or more of the following times: one or more of the wake-up start time of the second receiver, the wake-up duration of the second receiver, and the wake-up end time of the second receiver.

[0093] The above-mentioned wake-up start time is used to indicate the time when the terminal device wakes up the second receiver, or in other words, the terminal device starts to wake up the second receiver at the wake-up start time.

[0094] The wake-up duration is used to indicate the duration for which the second receiver remains awake, or in other words, the second receiver can remain in an activated state during the wake-up duration.

[0095] The above-mentioned wake-up end time is used to indicate the time when the terminal device turns off the second receiver, or in other words, the terminal device can turn off the second receiver at the wake-up end time to enter a dormant state.

[0096] In some implementations, the second information can be determined based on a first time offset, where the first time offset is the time offset between the reception time of the wake-up signal and the wake-up time of the second receiver. Therefore, the first time offset can also be called "wake-up offset time".

[0097] Taking the example of a wakeup time including the wakeup start time, the first time offset may be the time offset between the time the wakeup signal is received and the wakeup start time. Taking the example of a wakeup time including the wakeup end time, the first time offset may be the time offset between the time the wakeup signal is received and the wakeup end time. Taking the example of a wakeup time including the wakeup duration, the first time offset may be the time offset between the time the wakeup signal is received and a moment in the wakeup duration.

[0098] In addition, the time of receiving the wake-up signal may be the start time when the terminal device receives the wake-up signal, and the time of receiving the wake-up signal may also be the end time when the terminal device receives the wake-up signal, which is not limited in the embodiment of the present application.

[0099] For ease of understanding, the following, in conjunction with FIG10 , takes the time of receiving the wake-up signal as the end time of receiving the wake-up signal, and the wake-up time includes the wake-up start time as an example to introduce the first time offset of an embodiment of the present application. Referring to FIG10 , it is assumed that the wake-up signal is used to wake up the second receiver in an awake state during the wake-up period. Among them, the end time of receiving the wake-up signal is time 1, and the wake-up start time (or the start time of the wake-up period) is time 2. Accordingly, the first time offset can be a time offset between time 1 and time 2.

[0100] In some implementations, the first time offset may be determined based on one or more of the following information: terminal device capabilities; the time domain resources of the target channel corresponding to the wake-up signal; the time domain resources of the PF or PO corresponding to the wake-up signal; and the DRX duration corresponding to the wake-up signal. Of course, the second information may also be determined based on other information, which is not limited in this embodiment of the present application.

[0101] In some scenarios, different terminal devices may have different terminal device capabilities. For terminal devices with higher terminal device capabilities, the corresponding first time offset may be smaller. For terminal devices with lower terminal device capabilities, the corresponding first time offset may be larger. In this way, terminal devices with different terminal device capabilities may correspond to different first time offsets, which helps to improve the rationality of setting the wake-up time. Of course, in the embodiment of the present application, terminal devices with different terminal device capabilities may also correspond to the same first time offset to simplify the complexity of setting the wake-up time.

[0102] The above-mentioned terminal device capabilities may include the preparation time required to wake up the second receiver, wherein the preparation time may be, for example, the time required to start up the second receiver. Generally, the higher the terminal device capabilities, the shorter the preparation time required to wake up the second receiver. Conversely, the lower the terminal device capabilities, the more preparation time required to wake up the second receiver. Of course, the above-mentioned terminal device capabilities may also include the time it takes for the terminal device to process the wake-up signal. Therefore, in the embodiment of the present application, the above-mentioned terminal device capabilities may also be referred to as "terminal device processing capabilities." In addition, in the embodiment of the present application, the terminal device capabilities may also include other capabilities, which are not limited in the embodiment of the present application.

[0103] In the aforementioned time domain resource of the target channel corresponding to the wake-up signal, the target channel corresponding to the wake-up signal can be understood as the target channel that the wake-up signal wakes up the terminal device for reception. Accordingly, if the time interval between the time domain resource of the target channel and the time of reception of the wake-up signal is long, the corresponding first time offset can be large. Conversely, if the time interval between the time domain resource of the target channel and the time of reception of the wake-up signal is short, the corresponding first time offset can be small.

[0104] In some scenarios, waking up a terminal device is primarily to allow the terminal device to receive scheduling information for data or control information, and the scheduling information is typically obtained by receiving a PDCCH. Therefore, the target channel may be a PDCCH, and accordingly, the first time offset may be determined based on the transmission resource of the PDCCH.

[0105] Based on the PDCCH transmission method described above, the PDCCH transmission resource may be, for example, a PDCCH monitoring opportunity, or a time domain resource included in a CORESET corresponding to the PDCCH. For example, referring to FIG8 , the PDCCH transmission resource may be a time domain resource of a CORESET corresponding to the PDCCH, where the CORESET includes two symbols, and the first symbol position of the symbols included in the CORESET is symbol 0 in the time slot.

[0106] In the time domain resource of the PF or PO corresponding to the above-mentioned wake-up signal, the PF or PO corresponding to the wake-up signal can be understood as the PF or PO corresponding to the wake-up signal waking up the terminal device to receive the paging message. Accordingly, if the time interval between the time domain resource of the PF or PO and the reception time of the wake-up signal is long, then the corresponding first time offset can be large. Conversely, if the time interval between the time domain resource of the PF or PO and the reception time of the wake-up signal is short, then the corresponding first time offset can be small.

[0107] In the DRX duration corresponding to the above-mentioned wake-up signal, the DRX duration corresponding to the wake-up signal can be understood as the wake-up signal waking up the terminal device in an active state during the corresponding DRX duration. Accordingly, if the time interval between the DRX duration and the time when the wake-up signal is received is long, the corresponding first time offset can be large. Conversely, if the time interval between the DRX duration and the time when the wake-up signal is received is short, the corresponding first time offset can be small.

[0108] In some implementations, the first time offset may be preconfigured. For example, the network device may send configuration information to the terminal device in a preconfigured manner to configure the first time offset. The configuration information may be carried, for example, in RRC signaling or system messages. Of course, the configuration information may also be transmitted via dedicated signaling, which is not limited in this embodiment of the present application.

[0109] In other implementations, the first time offset may be predefined, for example, it may be predefined in the terminal device when the terminal device leaves the factory.

[0110] In other implementations, the first time offset can be flexibly configured for the terminal device. For example, the network device can configure the first time offset for the terminal device via a wake-up signal. Alternatively, the first time offset can be determined based on an indication of the wake-up signal. The wake-up signal can explicitly indicate the first time offset. For example, the wake-up signal can carry information indicating the first time offset. The wake-up signal can also implicitly indicate the wake-up start time. For example, the resource location of the wake-up signal is used to indicate the first time offset.

[0111] It should be noted that the above description mainly uses the wake-up start time as an example. Of course, the above wake-up start time can also be replaced with the wake-up end time. In this way, the time offset corresponding to the wake-up duration can be added to the first time offset to represent the time offset between the wake-up signal reception time and the wake-up end time. For the sake of brevity, this is not further described below.

[0112] In some implementations, the wake-up duration may be preconfigured, predefined, or flexibly configured, where the flexible configuration may be configured for the terminal device via a wake-up signal, for example. This embodiment of the present application does not limit this.

[0113] Generally speaking, for the same terminal device, information such as the time domain resources of the target channel corresponding to the wake-up signal, the time domain resources of the PF or PO corresponding to the wake-up signal, and the DRX duration corresponding to the wake-up signal are all changing, not to mention different terminal devices. Therefore, it is relatively complicated to determine the first time offset based on the above information. Whenever the above information changes, it may be necessary to redetermine the first time offset. Therefore, in order to simplify the complexity of determining the first time offset, the embodiment of the present application also provides a method for determining the wake-up time.

[0114] In an embodiment of the present application, the above-mentioned first time offset is divided into a preset second time offset and a third time offset, wherein the second time offset is a preset time offset with the reception time of the wake-up signal as the starting time, and the third time offset is a time offset from the end time of the second time offset to the wake-up start time of the second receiver.

[0115] In this way, the second time offset can be understood as a relatively fixed time offset, and the third time offset can be understood as an adjustable time offset. In addition, the third time offset can be indirectly determined through the configuration process of the target channel, the time domain resources of the PF, the time domain resources of the PO, and the DRX duration. In this way, only the relatively fixed second time offset can be determined, which helps to simplify the complexity of determining the first time offset.

[0116] As described above, the second time offset can be a relatively fixed time offset. Therefore, information related to the magnitude of the second time offset can also be relatively fixed information. For example, the magnitude of the second time offset can be determined based on the capabilities of the terminal device described above. The description of terminal device capabilities and the relationship between terminal device capabilities and the magnitude of the time offset have been previously described and will not be repeated here for the sake of brevity.

[0117] In an embodiment of the present application, the configuration method of the second time offset is the same as the configuration method of the first time offset described above, and can also be predefined, preconfigured, or determined by a wake-up signal indication. For details, please refer to the above introduction. For the sake of brevity, it will not be repeated here.

[0118] For ease of understanding, the third time offset is introduced below using scenarios such as a target channel, a paging message, and a DRX duration as examples.

[0119] Taking waking up the terminal device to receive the target channel as an example, the third time offset may include a time offset from the end time of the second time offset to the start time of the time domain resource of the target channel.

[0120] It should be noted that the time domain resources of the above-mentioned target channel may include the first time domain resources of the target channel. For example, when the target channel includes PDCCH, the first time domain resources of the target channel may be the first monitoring opportunity corresponding to the PDCCH, or the first CORSET corresponding to the PDCCH. The wake-up start time of the terminal device is the start time of the first time domain resource of the target channel, which avoids the need for the terminal device to wait for a period of time after waking up to reach the start time of the first time domain resource of the target channel, and helps to improve the energy saving level of the terminal device. Of course, in an embodiment of the present application, the time domain resources of the above-mentioned target channel may also include a certain time domain resource of the target channel, or may also include the last time domain resource of the target channel.

[0121] In addition, the start time of the above-mentioned time domain resource can be replaced by the end time of the time domain resource, or a certain moment corresponding to the time domain resource, which is not limited in the embodiment of the present application.

[0122] If the third time offset is a time offset from the end time of the second time offset to the start time of the first time domain resource of the target channel, accordingly, the wake-up start time may be the start time of the first time domain resource of the target channel received by the terminal device after the second time offset. Taking the target channel as PDCCH as an example, the wake-up start time may be the start time of the first listening opportunity (or the first CORSET) after the second time offset.

[0123] For ease of understanding, taking the target channel as PDCCH as an example, the relationship between the above-mentioned wake-up signal reception time and the wake-up start time is described in conjunction with FIG11 .

[0124] Referring to Figure 11, assuming that the wake-up signal is used to wake up the second receiver to detect PDCCH in CORSET1, and the reception end time of the wake-up signal is time 1, the wake-up start time (represented by time 2) can be the start time of the first CORSET (i.e., CORSET1) of the PDCCH received by the terminal device after the second time offset.

[0125] Correspondingly, the first time offset is the time offset between moment 1 and moment 2, and the first time offset includes a second time offset and a third time offset. The second time offset can be a preset time offset with moment 1 as the starting time, and the third time offset can be the time offset between the end time of the second time offset and the start time of CORSET1.

[0126] Taking waking up the terminal device to receive a paging message as an example, the third time offset may include a time offset from the end time of the second time offset to the start time of the time domain resource of the PF (or PO) corresponding to the paging message.

[0127] It should be noted that the above-mentioned PF (or PO) can be the first PF (or PO) after the second time offset. In this way, the wake-up start time is the start time of the first PF (or the first PO), which avoids the need for the terminal device to wait for a period of time after waking up to reach the start time of the first PF (or the first PO), thereby helping to improve the energy saving level of the terminal device. Of course, in the embodiment of the present application, the above-mentioned PF (or PO) can also be any PF (or any PO) after the second time offset, and the embodiment of the present application is not limited to this.

[0128] In addition, the start time of the above-mentioned time domain resource can be replaced by the end time of the time domain resource, or a certain moment corresponding to the time domain resource, which is not limited in the embodiment of the present application.

[0129] If the third time offset is the time offset from the end time of the second time offset to the start time of the first PF (or the first PO), accordingly, the wake-up start time can be the start time of the first PF or the first PO corresponding to the terminal device after the second time offset.

[0130] For ease of understanding, taking the target channel as PDCCH as an example, the relationship between the above-mentioned wake-up signal reception time and the wake-up start time is described in conjunction with FIG12 .

[0131] 12 , assuming that the wake-up signal is used to wake up the second receiver to detect the paging message in PO1, and the reception end time of the wake-up signal is moment 1, the wake-up start time (represented by moment 2) can be the start time of the first PO corresponding to the terminal device after the second time offset.

[0132] Correspondingly, the first time offset is the time offset between moment 1 and moment 2, and the first time offset includes a second time offset and a third time offset. The second time offset can be a preset time offset with moment 1 as the starting time, and the third time offset can be the time offset between the end time of the second time offset and the start time of PO1.

[0133] Taking a terminal device supporting the DRX mechanism as an example, the third time offset may include a time offset from the end time of the second time offset to the start time of the DRX duration.

[0134] It should be noted that the aforementioned DRX duration may be the first DRX duration after the second time offset. In this way, the wake-up start time is the start time of the first DRX duration, which avoids the terminal device having to wait for a period of time after waking up before reaching the start time of the first DRX duration, thereby helping to improve the energy efficiency of the terminal device. Of course, in the embodiment of the present application, the aforementioned DRX duration may also be any DRX duration after the second time offset, and the embodiment of the present application is not limited to this.

[0135] In addition, the start time of the above-mentioned DRX duration can be replaced by the end time of the DRX duration, or a certain moment in the DRX duration, which is not limited in the embodiment of the present application.

[0136] If the third time offset is the time offset from the end time of the second time offset to the start time of the first DRX period, accordingly, the wake-up start time can be the start time of the first DRX period corresponding to the terminal device after the second time offset.

[0137] For ease of understanding, taking a terminal device that supports the DRX mechanism as an example, the relationship between the above-mentioned wake-up signal reception time and the wake-up start time is introduced in conjunction with Figure 13.

[0138] Referring to Figure 13, assuming that the wake-up signal is used to wake up the second receiver in the active state in DRX period 1, and the reception end time of the wake-up signal is moment 1, the wake-up start time (represented by moment 2) can be the start time of the first DRX period (i.e., DRX period 1) corresponding to the terminal device after the second time offset.

[0139] Accordingly, the first time offset is the time offset between moment 1 and moment 2, and the first time offset includes a second time offset and a third time offset. The second time offset can be a preset time offset with moment 1 as the starting time, and the third time offset can be the time offset between the end time of the second time offset and the start time of DRX period 1.

[0140] In an embodiment of the present application, based on the above introduction, after configuring the second time offset for the terminal device, there is no need to configure the specific time offset value of the third time offset. Accordingly, the terminal device can determine the wake-up start time based on the above rules. For example, the rule may include that the wake-up start time may be the start time of the first time domain resource of the target channel received by the terminal device after the second time offset. For another example, the rule may include that the wake-up start time may be the start time of the time domain resource of the first PF or the first PO corresponding to the terminal device after the second time offset. For another example, the rule may include that the wake-up start time may be the start time of the first DRX duration corresponding to the terminal device after the second time offset.

[0141] In some implementations, the above rules may be preset, pre-configured, and pre-defined, which is not specifically limited in the present embodiment.

[0142] In the embodiments of the present application, in addition to determining the wake-up time based on the time offset as described above, the wake-up time can also be determined directly based on the indication of the wake-up signal, or in other words, the second information can be determined based on the indication of the wake-up signal. It should be noted that the definitions of the second information and wake-up time are the same as those described above, and can be referred to the above description. The following mainly describes how to determine the second time based on the indication of the wake-up signal.

[0143] In some implementations, the wake-up signal may indicate the second information in an explicit manner. For example, the wake-up signal may carry the second information, or in other words, the wake-up signal may carry an indication of the wake-up time.

[0144] In other implementations, the wake-up signal may implicitly indicate the second information. For example, the second information may be determined based on the resource location of the wake-up signal, or the wake-up time may be determined based on the resource location of the wake-up signal. Alternatively, there is a correspondence between the resource location of the wake-up signal and the second information, and the second information may be determined based on the resource location of the wake-up signal and the correspondence. The correspondence may be a many-to-one correspondence, or a one-to-one correspondence, which is not limited in the embodiments of the present application.

[0145] For a terminal device, generally, as long as any two of the wake-up start time, wake-up end time, and wake-up duration are known, the specific wake-up time can be determined. Accordingly, one or more of the above time information can be determined based on the wake-up signal indication.

[0146] Assuming that one of the above-mentioned time information can be determined based on the indication of the wake-up signal, the other time information can be obtained through other means. For example, when the wake-up end time can be determined based on the indication of the wake-up signal, the wake-up duration can be determined through a preconfigured or predefined manner. For another example, when the wake-up start time can be determined based on the indication of the wake-up signal, the wake-up duration can be determined through a preconfigured or predefined manner.

[0147] Assuming that any two of the above time information can be determined based on the indication of the wake-up signal, the remaining third information can be indicated in other ways or not at all. For example, when the wake-up end time and wake-up start time can be determined based on the indication of the wake-up signal, the wake-up duration can be determined in a preconfigured or predefined manner. For another example, when the wake-up start time and wake-up duration can be determined based on the indication of the wake-up signal, the wake-up end time can be omitted.

[0148] Of course, in the embodiment of the present application, the above three types of time information can be determined based on the indication of the wake-up signal, and the embodiment of the present application is not limited to this.

[0149] For ease of understanding, the following describes a schematic diagram of an embodiment of the present application indicating the wake-up time through a wake-up signal in conjunction with Figure 14. Assume that the second information carried by the wake-up signal includes the wake-up start time and the wake-up duration, and the second information indicates that the wake-up start time is time 1 and the wake-up duration is time length 1. Accordingly, when the terminal device receives the wake-up signal, it can wake up the second receiver and remain awake for a time period starting at time 1 and lasting for time length 1.

[0150] In addition, in an embodiment of the present application, the network device can also determine the second information based on the method introduced above. In this way, the network device can determine the wake-up time of the terminal device based on the second information. In this way, communicating with the terminal device based on the wake-up time helps to improve the success rate of communication between the network device and the terminal device.

[0151] It should be noted that in the solution where the network device determines the above wake-up time, the above-mentioned related methods involving network device configuration can be replaced by network device determination. For the sake of brevity, they will not be described one by one below.

[0152] Embodiment 2: The first information may include the third information.

[0153] In traditional communication technologies, a terminal device must operate in a single operating frequency domain (e.g., an activated downlink BWP or an activated uplink BWP). Similar to traditional communication technologies, after receiving a wake-up signal, the terminal device typically needs to determine the operating frequency domain (e.g., BWP) in which the secondary receiver will operate after waking up. However, there is currently no specification for the frequency domain bandwidth in which the secondary receiver operates after receiving the wake-up signal and waking up the secondary receiver.

[0154] Based on this, in an embodiment of the present application, the terminal device can determine the working frequency domain through the third information, wherein the above-mentioned third information indicates the working frequency domain after the second receiver is awakened.

[0155] For example, the terminal device may determine to activate the BWP according to the third information, wherein the activated BWP may be understood as the activated BWP operated after the second receiver of the terminal device is awakened by the awakening signal.

[0156] In some implementations, the third information is determined based on one or more of the following: operating frequency domain information of the second receiver during the last wake-up; predefined information; preconfigured information; and an indication of a wake-up signal. Of course, in the embodiments of the present application, the third information may also be determined by other means, which are not limited in the embodiments of the present application.

[0157] The third information may be determined based on the operating frequency domain information of the second receiver during the last wake-up period, and may include that the operating frequency domain of the second primary receiver is the operating frequency domain of the second receiver during the last wake-up period. Of course, the operating frequency domain of the second primary receiver may also include other operating frequency domains adjacent to the operating frequency domain of the second receiver during the last wake-up period.

[0158] It should be noted that the above-mentioned last wake-up period can be understood as the last wake-up period of this wake-up period, wherein this wake-up period can be understood as the wake-up period corresponding to the wake-up signal in step S910, or in other words, the wake-up period of the second main receiver awakened by the wake-up signal in step S910.

[0159] The third information described above can be determined based on predefined information, that is, the operating frequency domain can be predefined. For ease of understanding, the following describes the implementation of the predefined operating frequency domain in the embodiments of this application, using the operating frequency domain including an activated BWP as an example. It should be noted that in the embodiments of this application, configuring the activated BWP in a predefined manner is not limited to the following scenarios.

[0160] For example, the network device usually configures the default BWP ID for the terminal device through the default downlink BWP identifier (also known as "defaultDownlinkBWP-Id") information. Therefore, in an embodiment of the present application, the above-mentioned default BWP can be used as a predefined BWP, and accordingly, the activated BWP that works after the second receiver of the terminal device is awakened can be the default BWP.

[0161] For another example, in a carrier aggregation scenario, the network device may configure the ID of the default activated BWP after the secondary cell (Scell) is activated for the terminal device through the first activated downlink BWP identifier (also known as "firstActiveDownlinkBWP-Id") information. Therefore, in an embodiment of the present application, the above-mentioned default activated BWP can be used as a predefined BWP. Accordingly, after the second receiver of the terminal device is awakened, the BWP for the secondary cell can be the default activated BWP.

[0162] For another example, a network device typically configures multiple BWPs for a terminal device. The predefined BWP may be a specific BWP among the multiple BWPs. A specific BWP may have the smallest ID among the multiple BWPs. Of course, a specific BWP may also have the largest ID among the multiple BWPs.

[0163] It should be noted that the BWP with ID 0 is usually the initial BWP, which is used by idle terminal devices to receive system information and complete random access. Therefore, the BWP with the smallest ID mentioned above usually refers to the BWP with the smallest ID after excluding the initial BWP. Of course, in the embodiments of the present application, the BWP with the smallest ID can also be the initial BWP.

[0164] For another example, when the terminal device is in an idle state or an inactive state, the predefined BWP may be the initial BWP.

[0165] The third information may be determined based on pre-configuration information. In some implementations, the network device may send configuration information to the terminal device to configure the operating frequency domain. The configuration information may carry an identifier of the operating frequency domain (eg, an activated BWP ID).

[0166] The third information may be determined based on the indication of the wake-up signal. In some implementations, the wake-up signal may explicitly indicate the third information, that is, the wake-up signal may carry the third information, or the wake-up signal may carry an indication of the operating frequency domain.

[0167] In other implementations, the wake-up signal may implicitly indicate the third information. For example, the third information may be determined based on the resource location of the wake-up signal, or the operating frequency domain may be determined based on the resource location of the wake-up signal. Alternatively, there is a correspondence between the resource location of the wake-up signal and the third information, and the third information may be determined based on the resource location of the wake-up signal and the correspondence. The correspondence may be a many-to-one correspondence, or a one-to-one correspondence, which is not limited in the embodiments of the present application.

[0168] For ease of understanding, the following, combined with Figure 15 , uses the BWP as an example to describe the scheme for indicating the operating frequency domain through a wake-up signal in an embodiment of the present application. Assume that the network device has configured multiple BWPs for the terminal device, namely BWP1 to BWP3. The third information carried by the wake-up signal indicates that the active BWP is BWP1. Accordingly, after receiving the wake-up signal, the terminal device can determine, based on the third information, that the active BWP of the second receiver after wake-up is BWP1. BWP2 and BWP3 are inactive BWPs.

[0169] In addition, in an embodiment of the present application, the network device can also determine the third information based on the method introduced above. In this way, the network device can determine the activated BWP of the terminal device based on the third information. In this way, communicating with the terminal device based on the activated BWP helps to improve the success rate of communication between the network device and the terminal device.

[0170] It should be noted that in the solution of the network device determining the activation of the BWP, the above-mentioned related methods involving network device configuration can be replaced by network device determination, and for the sake of brevity, they will not be described one by one below.

[0171] As described above, the wake-up signal may directly carry the second information and / or the third information. Therefore, in order to improve the reliability of the wake-up information transmission, the information in the wake-up signal may be encoded.

[0172] In some implementations, the information in the wake-up signal may be encoded using one or more of the following encoding schemes: non-return-to-zero (NRZ) encoding, Manchester encoding, unipolar return-to-zero (Unipolar RZ) encoding, differential bi-phase (DBP) encoding, Miller encoding, and differential encoding. Of course, other encoding schemes may also be used in the embodiments of the present application, for example, encoding schemes newly introduced in future communication systems.

[0173] Taking Manchester encoding as an example, the correspondence between input bits and coded bits is shown in Table 1. As shown in Table 1, when the input bit is 0, the coded bit after Manchester encoding is 10. When the input bit is 1, the coded bit after Manchester encoding is 01.

[0174] Table 1

[0175] Input bit code bit 010101

[0176] In other embodiments, a checksum for verifying the information in the wake-up signal is carried in the wake-up signal to improve the reliability of the wake-up signal transmission. Accordingly, after receiving the wake-up signal, the receiving end can use the checksum to verify the accuracy of the information in the wake-up signal.

[0177] In some implementations, the check code may include a cyclic redundancy check (CRC) check code. For example, the transmitter may perform a CRC calculation on the information bits in the wake-up signal to generate CRC check bits (i.e., a CRC check code). Of course, in the embodiments of the present application, other check methods may also be used to obtain the check code, for example, a new check method introduced in future communication systems.

[0178] It should be noted that the above embodiments described in the embodiments of the present application can be used alone or in combination with each other, and the embodiments of the present application do not limit this. For ease of understanding, the following mainly introduces several possible combinations. It should be understood that the combination methods in the embodiments of the present application are not limited to the following.

[0179] For the sake of convenience, the scheme for determining the second information based on pre-configuration or preset rules in the above text is referred to as "Scheme 1"; the scheme for determining the second information based on the indication of the wake-up signal in the above text is referred to as "Scheme 2"; the scheme for determining the third information based on pre-configuration or preset rules (including determination based on predefined information and / or based on the working frequency domain during the last wake-up period) in the above text is referred to as "Scheme 3"; the scheme for determining the third information based on the indication of the wake-up signal in the above text is referred to as "Scheme 4".

[0180] In combination method 1, solution 1 and solution 2 may be combined to determine the second information.

[0181] Part of the time information in the second information can be determined by solution 1, and part of the time information can be determined by solution 2.

[0182] For example, the wake-up start time in the second information may be determined by solution 2, and the wake-up duration in the second information may be determined by solution 1.

[0183] For another example, the first time offset may be determined by solution 1, and the wake-up duration or the wake-up end time may be determined by solution 2.

[0192] The method embodiment of the present application is described in detail above in conjunction with Figures 1 to 15 . The device embodiment of the present application is described in detail below in conjunction with Figures 16 to 18 . It should be understood that the description of the method embodiment corresponds to the description of the device embodiment. Therefore, for parts not described in detail, reference can be made to the above method embodiment.

[0193] FIG16 is a schematic diagram of a terminal device according to an embodiment of the present application. The terminal device 1600 shown in FIG16 includes a processing unit 1610 .

[0194] If the first receiver of the terminal device receives a wake-up signal, the processing unit 1610 is configured to determine first information, where the first information is used to wake up the second receiver of the terminal device.

[0195] In a possible implementation manner, the first information includes second information, where the second information indicates a wake-up time of the second receiver.

[0196] In a possible implementation, the second information is determined based on a first time offset, where the first time offset is a time offset between a reception time of the wake-up signal and a wake-up time of the second receiver.

[0197] In one possible implementation, the first time offset is determined based on one or more of: terminal device capabilities; time domain resources of the target channel corresponding to the wake-up signal; time domain resources of the PF or PO corresponding to the wake-up signal; and the DRX duration corresponding to the wake-up signal.

[0198] In one possible implementation, the first time offset includes a second time offset and a third time offset, the second time offset being a preset time offset starting at the time of receiving the wake-up signal, and the third time offset being a time offset from the end time of the second time offset to the wake-up start time of the second receiver.

[0199] In one possible implementation, the wake-up start time is one of the following: the start time of the first time domain resource of the target channel received by the terminal device after the second time offset; the start time of the time domain resource of the first PF or the first PO corresponding to the terminal device after the second time offset; the start time of the first DRX period of the terminal device after the second time offset.

[0200] In a possible implementation manner, the second information is determined based on an indication of the wake-up signal.

[0201] In a possible implementation manner, the second information is determined based on an indication of the wake-up signal and includes the wake-up signal carrying the second information.

[0202] In a possible implementation manner, determining the second information based on an indication of the wake-up signal includes determining the second information based on a resource location of the wake-up signal.

[0203] In a possible implementation, the wake-up time includes one or more of a wake-up start time, a wake-up duration, and a wake-up end time.
