[0046] In the above embodiment, the terminal can monitor the LP WUS in the entire eDRX cycle, which is conducive to monitoring the LP WUS and waking up more timely, and facilitates more timely monitoring of paging to reduce paging delay.

[0047] In combination with the embodiments of the first aspect, in some embodiments, the first window completely overlaps, partially overlaps, or does not overlap with the PTW.

[0048] In the above embodiment, the terminal may determine the first window according to the PTW, so that the terminal monitors the LP WUS in the corresponding first window based on the position of the PTW, thereby improving monitoring efficiency.

[0049] In combination with the embodiment of the first aspect, in some embodiments, the starting position of the first window is before the first paging occasion PO in the PTW, and the starting position of the first window is separated from the starting position of the first PO by a first value.

[0050] In the above embodiment, the terminal may determine the position of the first window according to the position of the first PO in the PTW, thereby monitoring the LP WUS in a timely manner.

[0051] In combination with the embodiments of the first aspect, in some embodiments, the length of the first window is the same as the length of the PTW.

[0052] In the above embodiment, the terminal may determine the length of the window for monitoring the LP WUS according to the length of the PTW.

[0053] In conjunction with the embodiments of the first aspect, in some embodiments, the method further includes:

[0187] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0188] As shown in FIG. 1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0192] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0193] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0194] In some embodiments, the core network device can be a device including one or more network elements, or it can be multiple devices or device groups, each including all or part of one or more network elements. The network element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC).

[0195] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0196] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG. 1 , or a part of the main body thereof, but are not limited thereto.

[0197] The entities shown in Figure 1 are examples. The communication system may include all or part of the entities in Figure 1, and may also include other entities outside of Figure 1. The number and form of the entities are arbitrary. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0198] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication processing methods, and next-generation systems based on and extending these. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0199] In the disclosed embodiment, when the LP WUR of terminal 101 detects an LP WUS targeting the terminal, it can activate the MR and conduct normal communication transmission. Otherwise, terminal 101 can maintain the MR in sleep or deep sleep mode, significantly reducing MR power consumption. Furthermore, the LP WUR consumes extremely low power, resulting in greater power savings.

[0200] In the embodiment of the present disclosure, the terminal 101 in the RRC idle state or the RRC inactive state can monitor the LP WUS. When the LP WUS signal indicates that the terminal 101 needs to monitor paging, the terminal can wake up the MR and monitor the corresponding PO of the terminal through the MR.

[0201] In the embodiment of the present disclosure, the terminal 101 may determine the paging frame (PF) and paging occasion (PO) corresponding to the terminal according to the terminal identifier (UE ID) and the paging cycle. For example:

[0202] The PF system frame number (SFN) is determined by:

[0203] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N);

[0204] The index (Index) i_s of the PO is determined by:

[0205] i_s=floor(UE_ID / N)mod Ns;

[0206] PF_offset represents the offset, T represents the paging cycle, N represents the number of PFs in a paging cycle, and Ns represents the number of POs corresponding to a PF. mod represents the remainder operation, div represents the integer division operation, and floor represents the downward forensic operation.

[0207] In the embodiment of the present disclosure, for a terminal 101 in an RRC idle state or an RRC inactive state, the network device 102 may configure eDRX for the terminal 101. eDRX may include that configured by the core network (CN) (denoted as CN-eDRX) and that configured by the access network (denoted as RAN-eDRX). CN-eDRX may be used for terminals 101 in the RRC idle state or the RRC inactive state, while RAN-eDRX may be used for terminals in the RRC inactive state.

[0208] In this embodiment, when the eDRX cycle of terminal 101 is less than or equal to 1024 radio frames, terminal 101 needs to monitor the corresponding PO of the terminal in each eDRX cycle. When the eDRX cycle of terminal 101 is greater than 1024 radio frames, terminal 101 is configured with a paging transmission window (PTW).

[0209] In this embodiment, when the terminal 101 is configured with eDRX, it can determine the paging cycle T corresponding to the terminal, and then determine the PO corresponding to the terminal by the method of the above embodiment. The method for the terminal 101 to determine the paging cycle T is as follows:

[0210] For terminal 101 in RRC idle state:

[0211] If the core network configures the eDRX cycle T eDRX,CN When the time is less than or equal to 1024 wireless frames, T = T eDRX,CN ;

[0212] Otherwise, during the PTW configured by the CN, if the higher layer configures a UE specific DRX cycle value, T is determined by the minimum value between the higher layer configured UE specific DRX cycle value and the default DRX cycle value broadcasted by the System Information (SI).

[0213] In this case, T is defined within the PTW, but not outside the PTW, so the terminal 101 does not monitor paging outside the PTW.

[0214] For terminal 101 in RRC inactive state:

[0215] If T eDRX,CN and the T used eDRX,RAN (used T eDRX,RAN ) are less than or equal to 1024 wireless frames, T=min{T eDRX,RAN ,T eDRX,CN In this case, PTW is not configured and the terminal 101 needs to monitor paging at each T;

[0216] If T eDRX,CN Less than or equal to 1024 radio frames, and no T is configured or used eDRX,RAN , then T is composed of the terminal-specific DRX value configured by RRC and T eDRX,CN In this case, PTW is not configured and the terminal 101 needs to monitor paging at each T;

[0217] If TeDRX,CN If the wireless frame rate is greater than 1024 and PTW is configured, T is determined as follows:

[0218] If not configured or used T eDRX,RAN During a CN-configured PTW, T is determined by the minimum of the terminal-specific DRX cycle value configured by RRC, the terminal-specific DRX cycle value configured by higher layers (if any), and the default DRX cycle value broadcast in system information. Outside a CN-configured PTW, T is determined by the terminal-specific DRX cycle value configured by RRC. In this case, there is only a PTW for CN paging, not a PTW for RAN paging. T is defined both within and outside a PTW, but the values ​​are different. In this case, terminal 101 needs to monitor paging both within and outside a PTW.

[0219] If you use T eDRX,RAN Less than or equal to 1024 radio frames: During the PTW period configured by the CN, T is determined by the terminal-specific DRX cycle value (if configured by the higher layer), T eDRX,RAN and the default DRX cycle value broadcast in the system information. Outside the PTW configured by CN, T is determined by T eDRX,RAN In this case, there is only PTW for CN paging, but no PTW for RAN paging. T is defined both inside and outside the PTW, but the value of T is different. In this case, the terminal 101 needs to monitor paging both inside and outside the PTW.

[0220] If T eDRX,RAN Greater than 1024 radio frames, in this case there are both PTW for CN paging and PTW for RAN paging.

[0221] During the overlapping portion of the CN-configured PTW and the RAN-configured PTW, T is determined by the minimum of the terminal-specific DRX cycle value configured by RRC, the terminal-specific DRX cycle value configured by higher layers (if any), and the default DRX cycle value broadcast in the system information;

[0222] Outside of the CN-configured PTW and the RAN-configured PTW, T is determined by the minimum value of the terminal-specific DRX cycle value configured by the higher layer (if any) and the default DRX cycle value broadcast in the system information.

[0223] Outside of CN-configured PTW and during RAN-configured PTW, T is determined by the terminal-specific DRX cycle value configured by RRC.

[0224] In this case, T is defined only in the union of the PTW for CN paging and the PTW for RAN paging. The value of T is different in different time periods in the union, and the terminal 101 needs to monitor PO. There is no definition of T outside the union, and the terminal 101 does not need to monitor PO.

[0225] The embodiments of the present disclosure are described in conjunction with several scenarios when the terminal 101 is configured to run the eDRX mechanism and is configured to monitor the LP WUS:

[0226] Scenario 1: In the case where PTW is not configured, such as the following sub-scenarios case 1-1 to case 1-3, the terminal determines the LP WUS monitoring timing based on the PO location or monitors the LP WUS according to the LP WUS monitoring period configured by the network;

[0227] Case 1-1: RRC idle UE, T eDRX,CN <=1024 wireless frames;

[0228] Case 1-2: RRC inactive UE, T eDRX,CN <=1024 wireless frames, and T eDRX,RAN is<=1024 wireless frames;

[0229] Case 1-3: RRC inactive UE, T eDRX,CN <=1024 wireless frames, and T eDRX,RAN Not configured.

[0230] Scenario 2: PTW configuration, as shown in the following subscenarios: case 2-1 to case 2-4:

[0231] Case 2-1: RRC idle UE, T eDRX,CN >1024 wireless frames;

[0232] Case 2-2: RRC inactive UE, T eDRX,CN >1024 wireless frames, and T eDRX,RAN is<=1024 wireless frames;

[0233] Case 2-3: RRC inactive UE, T eDRX,CN >1024 wireless frames, and T eDRX,RAN Not configured;

[0234] Case 2-4: RRC inactive UE, T eDRX,CN >1024 wireless frames, and T eDRX,RAN is>1024 wireless frames;

[0235] In Cases 2-2 and 2-3, corresponding paging cycles (T) are defined within and outside the PTW, respectively, and have corresponding POs for the UE. In these two scenarios, the terminal determines the timing of monitoring the LP WUS based on the location of the PO or monitors the LP WUS according to the network-configured LP WUS monitoring cycle. In contrast, in Cases 2-1 and 2-4, T is not defined outside the PTW and there are no corresponding POs for the UE. Therefore, for these two scenarios, a method for the terminal to monitor the LP WUS is required.

[0236] FIG2a is an interactive diagram illustrating a method for monitoring a wake-up signal according to an embodiment of the present disclosure. As shown in FIG2a , an embodiment of the present disclosure relates to a method for monitoring a wake-up signal, the method comprising:

[0237] Step S2101 : The network device 102 sends first configuration information to the terminal 101 .

[0238] Optionally, terminal 101 is configured with an eDRX cycle and a PTW within the eDRX cycle. The time domain positions of the PTW and the eDRX cycle are shown in FIG2b . The PTW corresponding to terminal 101 may include one or more POs. Terminal 101 may determine whether to monitor the corresponding PO based on the monitoring result of the LP WUS. See the following embodiment for details.

[0239] In some embodiments, the PTW is a CN PTW configured by the CN, and the terminal is in an RRC idle state; or, the PTW is a union of a CN PTW and a RAN PTW configured by the RAN, and the terminal is in an RRC inactive state.

[0240] In some embodiments, the first configuration information includes at least one of the following: a first value, a length of the first window.

[0241] Optionally, the first configuration information may be sent via RRC signaling or SI.

[0242] Optionally, the terminal 101 receives first configuration information.

[0243] In some embodiments, the first window includes an LP WUS monitoring opportunity corresponding to the terminal 101. As described in the following step S2105, the terminal 101 may monitor the LP WUS in the first window through the LP WUR during the LP WUS monitoring opportunity.

[0244] Optionally, the terminal 101 may determine the LP WUS monitoring timing corresponding to the terminal in the following possible manners:

[0245] Method 1: The LP WUS monitoring timing corresponding to terminal 101 is determined by calculating a time offset forward from the time domain position of the PO corresponding to terminal 101. For example, in conjunction with the description of the aforementioned embodiment for determining the PF and PO, terminal 101 first determines the location of the PO corresponding to the terminal. Then, based on the time domain position of the PO, the forward offset duration is used to determine the LP WUS monitoring position corresponding to the terminal. In this method, there is a correspondence between the LP WUS monitoring timing of terminal 101 and the PO corresponding to terminal 101.

[0246] Method 2: The network configures an LP WUS listening cycle. There are multiple LP WUS listening opportunities in one cycle, and different listening opportunities correspond to different terminal groups (UE groups). For a terminal 101, there is only one LP WUS listening opportunity corresponding to the terminal 101 in one cycle. For example, the terminal 101 can find the LP WUS listening opportunity corresponding to the terminal in the cycle based on its terminal identifier (UE ID). In this method, the LP WUS listening opportunity corresponding to the terminal and the PO corresponding to the terminal are calculated using the UE ID and the corresponding formula, respectively. There is no direct correlation between the LP WUS listening opportunity corresponding to the terminal and the PO corresponding to the terminal.

[0247] It is worth noting that the above-mentioned method 1 and method 2 are only for illustration. There are many ways for the terminal to determine the corresponding LP WUS monitoring opportunity, which are not limited to the above-mentioned method 1 and method 2. Under other determination methods, the relevant embodiments of the embodiments of the present disclosure or the following embodiments are still applicable.

[0248] Optionally, there are multiple possible implementations for the position of the first window or the LP WUS monitoring opportunities included in the first window.

[0249] In a first possible implementation manner, such as configuration mode 1 or mode 2, the terminal 101 may determine the position of the first window according to the first value.

[0250] Optionally, the starting position of the first window is before the first PO in the PTW, and the starting position of the first window is separated from the starting position of the first PO by a first value.

[0251] Optionally, the first value may be recorded as T2, and the first value is greater than or equal to the terminal's wake-up delay to ensure that the terminal has sufficient time to use the MR to monitor the PO after receiving the LP WUS. The wake-up delay is the delay from when the MR is in a sleep state and monitors the LP WUS through the LP WUR to when the MR can normally transmit and receive data.

[0252] Optionally, the length of the first window is the same as the length of the PTW (PTW length). Alternatively, the length of the first window is configured by the network device 102, such as configuring the length value of the first window in the first configuration information.

[0253] In a second possible implementation, such as in configuration mode 1 or mode 2, the terminal 101 determines the position of the first window based on the eDRX cycle. For example, the first window may occupy the entire eDRX cycle, and the first window completely overlaps with the eDRX cycle. The terminal 101 monitors the LP WUS during the eDRX cycle. In this case, the network device 102 does not need to send the first configuration information for determining the position of the first window.

[0254] Optionally, in this embodiment, step S2101 may be omitted.

[0255] In a third possible implementation, such as in configuration mode 1 or mode 2, terminal 101 determines the position of the first window according to the PTW. For example, the first window completely overlaps, partially overlaps, or does not overlap with the PTW.

[0256] Optionally, if the first window completely overlaps with the PTW, terminal 101 may monitor the LP WUS within the PTW. In this case, step S2101 may be omitted, i.e., network device 102 does not need to send the first configuration information for determining the position of the first window. If the first window partially overlaps with the PTW or does not overlap at all, terminal 101 may determine the position of the first window using the first configuration information, or using other methods described in the following embodiments.

[0257] In a fourth possible implementation, as in configuration mode 1, the terminal 101 determines the LP WUS listening opportunities included in the first window based on the association between the LP WUS listening opportunities and the PO or PTW.

[0258] Optionally, the first window includes: an LP WUS monitoring opportunity corresponding to the PTW.

[0259] The LP WUS monitoring timing corresponding to the PTW, that is, based on the first approach, needs to be determined according to the corresponding PO, so that the LP WUS has an association or correspondence relationship with the corresponding PO or the PTW where the PO is located.

[0260] Optionally, the PO corresponding to the LP WUS monitoring opportunity may be any PO in the PTW.

[0261] Optionally, the PO corresponding to the LP WUS monitoring opportunity may be the first PO in the PTW, that is, the LP WUS monitoring opportunity corresponding to the PTW is the LP WUS monitoring opportunity corresponding to the first PO in the PTW. In combination with the description of the first approach, the LP WUS monitoring opportunity is determined according to the position of the first PO in the PTW.

[0262] Optionally, the LP WUS monitoring opportunity may be located outside the PTW, or may be located outside the PTW.

[0263] Optionally, in this embodiment, step S2101 may be omitted.

[0264] In a fifth possible implementation, as in the case of configuration mode 1, the LP WUS monitoring opportunities included in the first window may be LP WUS monitoring opportunities corresponding to POs within the PTW or LP WUS monitoring opportunities corresponding to POs outside the PTW.

[0265] Optionally, the first window includes one of the following:

[0266] LP WUS monitoring timing corresponding to PO in PTW;

[0267] LP WUS monitoring timing corresponding to some POs outside PTW;

[0268] LP WUS monitoring timing corresponding to all POs except PTW.

[0269] Optionally, when the first window includes LP WUS monitoring opportunities corresponding to some POs outside the PTW, the some POs are located in one or more second windows outside the PTW.

[0270] The second window is a window including POs other than the PTW, and the first window includes the LP WUS monitoring opportunities corresponding to the POs in the second window.

[0271] Optionally, in this embodiment, step S2101 may be omitted.

[0272] In some embodiments, in the above embodiments or implementations, the paging cycle T1 may be defined outside of the PTW.

[0273] Optionally, the paging cycle T1 of the PO outside the PTW is the same as or different from the paging cycle T of the PO within the PTW. The method for determining T can refer to the description of the above embodiment and will not be repeated here.

[0274] For example, the paging cycle of a PO outside the PTW is longer than the paging cycle of a PO within the PTW, thereby having a larger paging delay, which is beneficial to energy saving and resource consumption saving of the network device 102.

[0275] In one example, the paging cycle T1 of the PO outside the PTW is determined based on at least one of the UE specific DRX value by upper layer, the default DRX value broadcast in system information, and the UE specific DRX value configured by RRC.

[0276] For example, if the terminal is in the RRC idle state, the paging cycle T1 is: min{terminal-specific DRX cycle value configured by the higher layer, default DRX cycle value broadcast by the system information};

[0277] For another example, if the terminal is in the RRC inactive state, the paging cycle is one of the following:

[0278] min{terminal-specific DRX cycle value configured by the upper layer, the default DRX cycle value broadcast by the system information, and the terminal-specific DRX cycle value configured by the network device through RRC};

[0279] min{default DRX cycle value broadcast by system information, terminal-specific DRX cycle value configured by the network device through RRC};

[0280] The terminal-specific DRX cycle value configured by the network device through RRC.

[0281] In this embodiment, after determining the paging cycle, the terminal 101 can determine the relevant information of PO and PF based on the method of the aforementioned embodiment, so as to facilitate monitoring its corresponding PO at an appropriate location; and in the case of configuration method one, the terminal 101 can also determine the corresponding LP WUS monitoring timing based on PO, so as to monitor LP WUS at an appropriate location.

[0282] It is worth noting that when step S2101 is omitted, the implementations regarding the first window, LP WUS monitoring opportunity or paging cycle T1 can still be applied to other related embodiments.

[0283] Step S2102 , the network device 102 sends second configuration information to the terminal 101 .

[0284] Optionally, the second configuration information includes at least one of the following:

[0285] The number of first windows, the length of the first window, and the position of the first window.

[0286] Optionally, terminal 101 receives second configuration information.

[0287] In some embodiments, the second configuration information includes the above three parameters. According to the above three parameters, the terminal 101 monitors the LP WUS in each first window when executing step S2105.

[0288] In some embodiments, the position of the first window is determined by the terminal according to the terminal identifier (UE ID). In this case, the second configuration information may configure some parameters therein, such as the number of first windows and the length of the first window. Terminal 101 calculates the position of the first window according to the UE ID and / or other network configured parameters.

[0289] In some embodiments, the second configuration information may be sent via RRC signaling or SI.

[0290] Optionally, the first configuration information and the second configuration information can be sent independently, such as the network device 102 first executes step S2101 or first executes step S2102; or the first configuration information and the second configuration information are sent through the same signaling, such as the network device 102 simultaneously executes steps S2101 and S2102.

[0291] Optionally, the position of the first window may be represented by time domain information.

[0292] In some embodiments, one or more first windows are configured outside of the PTW.

[0293] For example, the second configuration information is used to determine a first window parameter outside the PTW, so that the terminal 101 determines a position for monitoring the LP WUS outside the PTW.

[0294] Optionally, the lengths of the one or more first windows may be the same.

[0295] Optionally, the length of the first window is greater than or equal to a LP WUS sending cycle (LP WUS cycle), so that there will be a corresponding LP WUS monitoring opportunity within the first window.

[0296] Optionally, when there are multiple first windows, the multiple first windows are distributed at equal intervals.

[0297] Optionally, the interval is a time interval or a duration, and the multiple first windows are evenly spaced, that is, the time intervals between the quality and safety monitoring of any two adjacent first windows are the same.

[0298] In some embodiments, step S2102 may be omitted. For example, in the first possible implementation or the fourth possible implementation, step S2102 may be omitted.

[0299] Step S2103 : The network device 102 sends third configuration information to the terminal 101 .

[0300] Optionally, the third configuration information includes at least one of the following:

[0301] The number of second windows, the length of the second windows, and the position of the second windows.

[0302] Optionally, terminal 101 receives third configuration information.

[0303] In some embodiments, the third configuration information includes the above three parameters. The terminal 101 determines the second window according to the above three parameters, and can further determine the first window corresponding to the PO in the second window.

[0304] In some embodiments, the position of the second window is determined by the terminal according to the terminal identifier. In this case, the third configuration information may configure some parameters therein, such as the number of second windows and the length of the second window, and the terminal 101 calculates the position of the second window according to the UE ID and / or other network configured parameters.

[0305] In some embodiments, the third configuration information may be sent via RRC signaling or SI.

[0306] Optionally, the first configuration information, the second configuration information and the third configuration information can be sent independently, wherein the execution order of steps S2101 to S2103 can be adjusted or exchanged; or, at least two of the first configuration information, the second configuration information and the third configuration information are sent via the same signaling, such as the network device 102 executes steps S2101 to S2103 simultaneously.

[0307] In some embodiments, when there are multiple second windows, the multiple second windows are evenly spaced, for example, the time interval between every two adjacent second windows is the same.

[0308] Optionally, the length of the second window is greater than or equal to the paging cycle of the PO outside the PTW, so that the UE will definitely have a corresponding PO in the second window and a corresponding LP WUS monitoring opportunity in the first window.

[0309] In step S2104 , the network device 102 sends instruction information to the terminal 101 .

[0310] Optionally, the indication information is used to instruct the terminal whether to monitor the LP WUS corresponding to the PO other than the PTW.

[0311] Optionally, step S2104 may be performed in configuration mode one.

[0312] Optionally, terminal 101 receives the indication information.

[0313] Optionally, network device 102 may explicitly indicate, through indication information, whether to enable terminal 101 to monitor the LP WUS corresponding to POs outside the PTW. For example, the indication may be performed using a single bit.

[0319] Optionally, when the terminal 101 does not monitor the LP WUS corresponding to the terminal, or the LP WUS indicates not to wake up, the terminal 101 may maintain the MR sleep state, that is, there is no need to wake up the MR, thereby achieving energy saving.

[0320] Step S2106: Wake up and monitor the corresponding PO.

[0321] Optionally, the terminal 101 wakes up, that is, the MR switches from a sleep state to a normal state of sending and receiving data.

[0370] The embodiments of the present disclosure provide a method for monitoring LP WUS when the UE is configured with eDRX, which can achieve better energy saving or reduce paging delay. To facilitate understanding of the embodiments of the present disclosure, some specific embodiments are listed below:

[0371] Example 1:

[0372] LP WUS configuration method 1: The LP WUS monitoring timing corresponding to terminal 101 is determined by calculating a time offset forward from the time domain location of the PO corresponding to terminal 101. For example, referring to the description of the above embodiment, terminal 101 first determines the location of the PO corresponding to the terminal. Then, based on the time domain location of the PO, the forward offset duration is used to determine the LP WUS monitoring location corresponding to the terminal. In this method, there is a correspondence between the LP WUS monitoring timing of terminal 101 and the PO corresponding to terminal 101.

[0373] The implementation of the first embodiment may include the following two optional methods:

[0374] For option 1, refer to the following example:

[0375] Example 1:

[0376] The UE needs to monitor the LP WUS corresponding to the PO in the PTW, where the PTW is the CN PTW and / or the RAN PTW.

[0377] Example 2:

[0378] Based on Example 1, the UE also needs to monitor the LP WUS corresponding to the PO outside the PTW.

[0379] Optionally, when the UE is outside the PTW, the cycle for performing paging monitoring is T1.

[0380] Optionally, T1 may be the same as or different from the paging cycle within the PTW.

[0381] Optionally, T1 is determined by at least one of a terminal-specific discontinuous reception (DRX) cycle value configured by a higher layer, a default DRX cycle value broadcasted in system information, and a terminal-specific DRX cycle value configured by the network device via RRC. For example, T1 = min{terminal-specific DRX cycle value configured by a higher layer, default DRX cycle value broadcasted in system information}.

[0382] Example 3:

[0383] Based on Example 1, the UE also needs to monitor the LP WUS corresponding to the PO in the third window.

[0384] Optionally, the third window may correspond to the second window in the aforementioned embodiment.

[0385] Optionally, the third window is located outside the PTW.

[0386] Optionally, there may be one or more third windows. When there are multiple third windows, the third windows are distributed at equal intervals in a time period outside the PTW within the eDRX cycle.

[0387] Optionally, the number of third windows, the length of a single window, and the position of the third window are configured by the base station. Alternatively, the number of third windows and the length of a single window are configured by the network, and the position of the third window is calculated by the UE based on the UE ID and / or other network-configured parameters.

[0388] Optionally, within the third window, the cycle for the UE to perform paging monitoring is T1.

[0389] Optionally, T1 may be the same as or different from the paging cycle within the PTW. In one embodiment, the length of the third window is greater than or equal to T1, so that the UE will definitely have a corresponding PO within the third window.

[0390] Optionally, T1 is determined by at least one of a terminal-specific discontinuous reception (DRX) cycle value configured by a higher layer, a default DRX cycle value broadcasted in system information, and a terminal-specific DRX cycle value configured by the network device via RRC. For example, T1 = min{terminal-specific DRX cycle value configured by a higher layer, default DRX cycle value broadcasted in system information}.

[0391] Example 4:

[0392] Based on Example 2, the UE also needs to monitor the LP WUS corresponding to all POs other than PTW within the eDRX cycle.

[0393] Example 5:

[0394] Based on any one of Examples 2 to 4, the base station may determine whether to start monitoring outside the PTW in any one of Examples 2 to 4 through explicit signaling.

[0395] Example 6:

[0396] Based on any one of Examples 2 to 5, the UE is in the RRC idle state and is configured with a CN PTW.

[0397] Example 7:

[0398] Based on Example 1, the UE also needs to monitor the LP WUS corresponding to the PO outside the union of the CN PTW and the RAN PTW.

[0399] Optionally, the cycle for the UE to perform paging monitoring outside the union of PTWs is T1.

[0400] Optionally, T1 may be the same as or different from the paging cycle within the PTW.

[0401] Optionally, T1 is determined by at least one of a terminal-specific discontinuous reception DRX cycle value configured by a higher layer, a default DRX cycle value broadcast by system information, and a terminal-specific DRX cycle value configured by the network device through RRC.

[0402] For example, T1=min{terminal-specific DRX cycle value configured by high layers, default DRX cycle value broadcast by system information, terminal-specific DRX cycle value configured by RRC}, or T1=min{default DRX cycle value broadcast by system information + terminal-specific DRX cycle value configured by RRC}, or T1=terminal-specific DRX cycle value configured by RRC.

[0403] Example 8:

[0404] Based on Example 1 or Example 7, the UE also needs to monitor the LP WUS corresponding to the PO in the third window.

[0405] Optionally, the third window may correspond to the second window in the aforementioned embodiments in some embodiments.

[0406] Optionally, the third window is located outside the union of the CN PTW and the RAN PTW of the PTW.

[0407] Optionally, there may be one or more third windows. When there are multiple third windows, the third windows are evenly spaced in a time period outside the PTW set within the eDRX cycle.

[0408] Optionally, the number of third windows, the length of a single window, and the position of the third window are configured by the base station. Alternatively, the number of third windows and the length of a single window are configured by the network, and the position of the third window is calculated by the UE based on the UE ID and / or other network-configured parameters.

[0409] Optionally, within the third window, the cycle for the UE to perform paging monitoring is T1.

[0410] Optionally, T1 may be the same as or different from the paging cycle within the PTW. In one embodiment, the length of the third window is greater than or equal to T1, so that the UE will definitely have a corresponding PO within the third window.

[0411] Optionally, T1 is determined by at least one of a terminal-specific discontinuous reception DRX cycle value configured by a higher layer, a default DRX cycle value broadcast by system information, and a terminal-specific DRX cycle value configured by the network device through RRC.

[0412] For example, T1=min{terminal-specific DRX cycle value configured by high layers, default DRX cycle value broadcast by system information, terminal-specific DRX cycle value configured by RRC}, or T1=min{default DRX cycle value broadcast by system information + terminal-specific DRX cycle value configured by RRC}, or T1=terminal-specific DRX cycle value configured by RRC.

[0413] Example 9:

[0414] Based on Example 7, the UE also needs to monitor the LP WUS corresponding to all POs except the union of the CN PTW and the RAN PTW within the eDRX cycle.

[0415] Example 10:

[0416] Based on any one of Examples 7 to 9, the base station may determine whether to start monitoring outside the PTW union set of any one of Examples 7 to 9 through explicit signaling.

[0417] Example 11:

[0418] Based on any one of Examples 7 to 10, the UE is in the RRC inactive state and is configured with the CN PTW and the RAN PTW.

[0419] Example 12:

[0420] Based on any one of Examples 1 to 11, when the UE monitors the LP WUS, the UE wakes up to monitor the PO corresponding to the LP WUS.

[0421] For option 2, refer to the following example:

[0422] Example 13:

[0423] In one eDRX cycle, the UE monitors the LP WUS monitoring opportunity corresponding to the PTW.

[0424] Optionally, the monitoring timing corresponding to the PTW may be the LP WUS monitoring timing corresponding to the first PO in the PTW.

[0425] Optionally, the LP WUS monitoring opportunity may be located outside the PTW, or may be located outside the PTW.

[0426] Optionally, if LP WUS is detected and the LP WUS instructs the UE to wake up, the UE wakes up in the PTW and monitors the PO in the PTW; if no LP WUS is detected, or the LP WUS instructs not to wake up, the UE will not wake up and will not monitor any PO in the PTW.

[0427] Example 14:

[0428] Based on Example 13, the UE is in the RRC idle state and is configured with a CN PTW. The PTW is a CN PTW.

[0429] Example 15:

[0430] Based on Example 13, the UE is in the RRC Inactive state and is configured with a CN PTW and a RAN PTW. The PTW is the CN PTW or the RAN PTW or the union of the CN PTW and the RAN PTW (for example, the CN PTW and the RAN PTW have a time domain overlap).

[0431] Example 2:

[0432] LP WUS configuration method 2, that is, the network configures the LP WUS monitoring cycle (cycle), with multiple LP WUS monitoring opportunities in one cycle, and different monitoring opportunities correspond to different terminal groups (UE groups). For a terminal 101, there is only one LP WUS monitoring opportunity corresponding to the terminal 101 in one cycle. For example, the terminal 101 can find the LP WUS monitoring opportunity corresponding to the terminal in the cycle based on its terminal identifier (UE ID). In this method, the LP WUS monitoring opportunity corresponding to the terminal and the PO corresponding to the terminal are calculated respectively by the UE ID and the corresponding formula. There is no direct correlation between the LP WUS monitoring opportunity corresponding to the terminal and the PO corresponding to the terminal.

[0433] Alternatively, the second embodiment is also applicable to the first LP WUS configuration method.

[0434] The implementation of the second embodiment may include the following examples:

[0435] Example 16:

[0436] In the eDRX cycle, the UE monitors the LP WUS in the fourth window.

[0437] Optionally, the fourth window may correspond to the first window in the aforementioned embodiments in some embodiments.

[0438] Optionally, the fourth window is the PTW.

[0439] Optionally, the fourth window may partially overlap or not overlap with the PTW.

[0440] Optionally, the fourth window may also be the entire eDRX cycle.

[0441] Example 17:

[0442] Based on Example 16, the starting position of the fourth window is earlier than the time domain starting position of the first PO in the PTW by T2, where T2 is a value configured by the base station. Generally, T2 is greater than or equal to the UE wake-up delay.

[0443] Optionally, the duration of T2 corresponds to the first value in the aforementioned embodiment.

[0444] Optionally, the duration of the fourth window is equal to the duration of the PTW, or may be another value configured by the base station.

[0445] Example 18:

[0446] Based on Example 16, the UE may be further configured to monitor the LP WUS in the fifth window. The fifth window is outside the PTW.

[0447] Optionally, the fifth window may correspond to the first window in the aforementioned embodiments in some embodiments.

[0448] Optionally, there may be one or more fifth windows. When there are multiple fifth windows, the fifth windows are evenly spaced in a time period outside the PTW within the eDRX cycle.

[0449] Optionally, the number of fifth windows, the length of a single window, and the position of the fifth window are configured by the base station, or the number of fifth windows and the length of a single window are configured by the network, and the position of the fifth window is calculated by the UE based on the UE ID and / or other network configured parameters.

[0450] In one embodiment, the length of the fifth window is greater than or equal to the LP WUS cycle, so that the UE will have a corresponding LP WUS monitoring opportunity within the first window.

[0451] Example 19:

[0452] Based on any one of Examples 16 to 18, the UE is in the RRC idle state and is configured with a CN PTW. The PTW is a CN PTW.

[0453] Example 20:

[0454] Based on any one of Examples 16 to 18, the UE is in the RRC Inactive state and is configured with a CN PTW and a RAN PTW. The PTW is the CN PTW or the RAN PTW or the union of the CN PTW and the RAN PTW (for example, the CN PTW and the RAN PTW have a time domain overlap).

[0455] Example 21:

[0456] Based on any one of Examples 16 to 20, in addition to the PTW, a period T1 during which the UE monitors paging is defined.

[0457] Optionally, T1 is determined by at least one of a terminal-specific discontinuous reception DRX cycle value configured by a higher layer, a default DRX cycle value broadcast by system information, and a terminal-specific DRX cycle value configured by the network device through RRC.

[0458] For example, T1=min{terminal-specific DRX cycle value configured by high layers, default DRX cycle value broadcast by system information, terminal-specific DRX cycle value configured by RRC}, or T1=min{default DRX cycle value broadcast by system information + terminal-specific DRX cycle value configured by RRC}, or T1=terminal-specific DRX cycle value configured by RRC.

[0459] Example 22:

[0460] Based on any one of Examples 16 to 21, when the terminal 101 monitors the LP WUS, the UE wakes up to monitor the PO corresponding to the nearest UE after waking up.
