Method and device for transmitting paging message and readable storage medium

Abstract

The invention relates to a paging message transmission method and device and a readable storage medium. The method comprises the following steps: monitoring a low-power-consumption wakeup signal LP WUS through a low-power-consumption receiver in a first time period of an extended discontinuous reception (e-DRX) period; and after receiving the LP WUS, the main receiver is converted from a sleep state to a working state, and monitors a PO corresponding to the user equipment. In the method disclosed by the invention, in the e-DRX period, the user equipment can monitor the LP WUS by adopting the low-power-consumption receiver, awaken the main receiver after monitoring the LP WUS, and monitor the corresponding PO so as to monitor the paging message. Before monitoring the LP WUS, the main receiver can be kept in a sleep state, so that the energy consumption of the user equipment in an e-DRX scene is further saved in combination with an LP WUS mechanism.

Description

Method, device and readable storage medium for transmitting paging message Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device, and readable storage medium for transmitting a paging message. Background Art

[0002] To reduce power consumption in user equipment (UE) during communications, 3GPP defines extended discontinuous reception (eDRX) for idle UEs. When an eDRX cycle is configured, the UE monitors its corresponding paging opportunities (POs) during the paging transmission window (PTW) of the eDRX cycle. In scenarios where eDRX is configured, further energy conservation is crucial.

[0003] Summary of the Invention

[0004] The present disclosure provides a method, an apparatus, and a readable storage medium for transmitting a paging message.

[0005] In a first aspect, the present disclosure provides a method for monitoring a paging message, which is performed by a user equipment, the method comprising:

[0006] During a first period of an extended discontinuous reception e-DRX cycle, monitoring a low power wake-up signal LP WUS by a low power receiver;

[0007] After receiving the LP WUS, the main receiver switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment.

[0008] In the disclosed method, during an e-DRX cycle, a user device can use a low-power receiver to monitor for LP WUS. Upon detecting an LP WUS, the user device can wake up the primary receiver and monitor the corresponding PO for paging messages. Prior to detecting an LP WUS, the primary receiver can remain in a sleep state. This, combined with the LP WUS mechanism, further reduces user device energy consumption in e-DRX scenarios.

[0009] In some possible implementations, the first time period includes: a time period corresponding to a paging time window PTW in the e-DRX cycle.

[0010] In some possible implementations, the first time period includes: all time periods in the e-DRX cycle.

[0011] In some possible implementations, the first time period includes: a time period corresponding to a PTW and a time period corresponding to at least one listening window, wherein the listening window is used to monitor the LP WUS.

[0012] In some possible implementations, the at least one listening window is located in a period outside the PTW in the e-DRX cycle.

[0013] In some possible implementations, the method further includes:

[0014] During a period other than the first period in the e-DRX cycle, the LP WUS and / or the PO are not monitored.

[0015] In some possible implementations, the method further includes:

[0016] Configuration information sent by a network device is received, where the configuration information is used to configure the at least one listening window.

[0017] In some possible implementations, the configuration information includes at least one of the following:

[0018] a start time of the at least one listening window;

[0019] a duration of the at least one listening window;

[0020] The number of the listening windows.

[0021] In some possible implementations, monitoring the paging opportunity PO corresponding to the user equipment includes:

[0022] If the user equipment does not receive a corresponding paging message after receiving the set duration of the LP WUS, the main receiver enters a sleep state and monitors the LP WUS through the low power receiver.

[0023] In a second aspect, the present disclosure provides a method for sending a paging message, which is performed by a network device, the method comprising:

[0024] In the first period of the e-DRX cycle, before sending the paging message, an LP WUS is sent to the user equipment.

[0025] In the disclosed method, during an e-DRX cycle, the network device first sends an LP WUS to wake up the user equipment before sending a paging message. The user equipment can use a low-power receiver to listen for the LP WUS. Before receiving the LP WUS, the user equipment's main receiver can remain in a sleep state. This, combined with the LP WUS mechanism, further reduces user equipment energy consumption in e-DRX scenarios.

[0026] In some possible implementations, the method further includes:

[0027] During a period other than the first period in the e-DRX cycle, the LP WUS and / or paging information is not sent.

[0028] In some possible implementations, the first period includes one of the following:

[0029] All time periods in the e-DRX cycle;

[0030] The period corresponding to the PTW in the e-DRX cycle;

[0031] A time period corresponding to the PTW and a time period corresponding to at least one listening window, wherein the listening window is used to monitor the LP WUS.

[0032] In some possible implementations, the at least one listening window is located in a period outside the PTW in the e-DRX cycle.

[0033] In some possible implementations, the method further includes:

[0034] Sending configuration information to the user equipment, where the configuration information is used to configure the at least one listening window.

[0035] In some possible implementations, the configuration information includes at least one of the following:

[0036] a start time of the at least one listening window;

[0037] a duration of the at least one listening window;

[0038] The number of the listening windows.

[0069] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0070] As shown in Figure 1, a method for transmitting a paging message provided in an embodiment of the present disclosure may be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation and may be connected to multiple component carriers of the network device 102, including a primary component carrier and one or more secondary component carriers.

[0071] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.

[0072] The user equipment 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, or a terminal device, etc. The user equipment 101 may have wireless transceiver functions, and may be capable of communicating (e.g., wireless communication) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0073] Among them, the user equipment 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc.

[0074] The network device 102 may be an access network device (or access network point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. The network device 102 may specifically include a base station (BS), or a base station and a radio resource management device for controlling the base station. The network device 102 may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station. The network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

[0075] For example, the network device 102 includes but is not limited to: the next generation base station (gnodeB, gNB) in 5G, the evolved node B (eNB) in the LTE system, the radio network controller (RNC), the node B (NB) in the WCDMA system, the wireless controller under the CRAN system, the base station controller (BSC), the base transceiver station (BTS) in the GSM system or the CDMA system, the home base station (for example, home evolved nodeB, or home node B, HNB), the baseband unit (BBU), the transmission point (TRP), the transmitting point (TP) or the mobile switching center, etc.

[0076] During the eDRX cycle, user equipment 101 monitors the PO corresponding to the UE during the PTW period. Outside of the PTW period, it does not need to monitor the PO and can remain in a sleep state. Monitoring the PO by user equipment 101 requires the RF and baseband processing hardware to be enabled. In scenarios where eDRX is configured, maintaining the UE 101 monitoring state during the PTW period may waste energy, necessitating further efforts to reduce UE energy consumption.

[0077] The present disclosure provides a method for transmitting a paging message. Referring to FIG. 2 , FIG. 2 is a diagram illustrating a method for transmitting a paging message according to an exemplary embodiment. As shown in FIG. 2 , the method includes steps S201 to S203, specifically:

[0078] In step S201 , the user equipment 101 monitors a low power wake-up signal (LP WUS) via a low power receiver in a first period of an extended discontinuous reception (e-DRX) cycle.

[0079] In some possible implementations, the e-DRX cycle may be configured by the network device 102 .

[0080] In one example, the e-DRX cycle may be configured between 20.48 seconds (s) and 2.92 hours (h).

[0081] In some possible implementations, the first time period may be the entire time period corresponding to the e-DRX cycle, or a portion of the time period therein.

[0082] In some possible implementations, the user equipment 101 uses a separate low-power receiver to monitor the LP WUS, and the power consumption of the low-power receiver is much smaller than the power consumption of the main receiver of the user equipment 101 .

[0083] In some possible implementations, when no LP WUS is monitored, the primary receiver of the user equipment 101 may be in a sleep state, which does not monitor the Physical Downlink Control Channel (PDCCH), such as not monitoring paging downlink control information (paging DCI).

[0084] Step S202: The network device 102 sends an LP WUS to the user equipment before sending a paging message in the first period of the e-DRX cycle.

[0085] In some possible implementations, when the network device 102 needs to send a paging message, it will first send an LP WUS to wake up the user equipment 101. During the first period, the user equipment 101 monitors the LP WUS via the low power transceiver.

[0086] In some possible implementations, the network device 102 notifies the user equipment 101 to monitor the paging opportunity (PO) corresponding to the UE itself by sending an LP WUS.

[0087] In step S203, after receiving the LP WUS, the main receiver of the user equipment 101 switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment.

[0088] In some possible implementations, after receiving the LP WUS, the user equipment 101 wakes up the main receiver to monitor the corresponding PO, so as to receive the paging DCI corresponding to the UE in the search space corresponding to the PO.

[0089] In the disclosed embodiment, during the first period of the e-DRX cycle, when network device 102 needs to send a paging message, it first sends an LP WUS to wake up user equipment 101. User equipment 101 can use a low-power receiver to monitor for the LP WUS. After detecting the LP WUS, it can then wake up the primary receiver and monitor the corresponding PO for paging messages. Before detecting the LP WUS, the primary receiver can remain in a sleep state. This, combined with the LP WUS mechanism, further reduces user equipment energy consumption in e-DRX scenarios.

[0090] The present disclosure provides a method for monitoring paging messages, which is performed by user equipment 101. Referring to FIG3 , FIG3 is a method for monitoring paging messages according to an exemplary embodiment. As shown in FIG3 , the method includes steps S301 to S302, specifically:

[0091] In step S301 , the user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception e-DRX cycle.

[0092] Step S302: After receiving the LP WUS, the main receiver switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment.

[0093] In some possible implementations, the e-DRX cycle may be configured by the network device 102. For example, the e-DRX cycle may be configured to be between 20.48 seconds and 2.92 hours.

[0094] In some possible implementations, the first time period may be the entire time period corresponding to the e-DRX cycle, or a portion of the time period therein.

[0095] In some possible implementations, the user equipment 101 uses a separate low-power receiver to monitor the LP WUS, and the power consumption of the low-power receiver is much smaller than the power consumption of the main receiver of the user equipment 101 .

[0096] In some possible implementations, when the LP WUS is not monitored, the primary receiver of the user equipment 101 may be in a sleep state, which does not monitor the paging DCI.

[0097] In some possible implementations, POs corresponding to multiple user equipments 101 may be configured in one e-DRX cycle, and each user equipment 101 needs to monitor its own corresponding PO.

[0098] In the disclosed embodiments, during an e-DRX cycle, user equipment 101 can use a low-power receiver to monitor for LP WUS. Upon detecting the LP WUS, the primary receiver can be awakened to monitor the corresponding PO for paging messages. Prior to detecting the LP WUS, the primary receiver can remain in a sleep state. This, combined with the LP WUS mechanism, further reduces user equipment energy consumption in e-DRX scenarios.

[0099] The present disclosure provides a method for monitoring paging messages, which is performed by user equipment 101. The method includes steps S301 to S302, specifically:

[0100] In step S301 , the user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception e-DRX cycle.

[0101] Step S302: After receiving the LP WUS, the main receiver switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment.

[0102] The first time period includes: a time period corresponding to a paging time window PTW in an e-DRX cycle.

[0103] In some possible implementations, only one PTW is configured in one e-DRX cycle.

[0104] In some possible implementations, during the PTW period, the user equipment 101 may still monitor the LP WUS through the low power receiver. Before monitoring the LP WUS, the user equipment 101 may remain in a sleep state.

[0105] In the embodiment of the present disclosure, the user equipment 101 may first monitor the LP WUS through the low power receiver during the PTW of the e-DRX cycle. After monitoring the LP WUS, the main receiver wakes up from the sleep state to monitor the PO, thereby achieving UE energy saving during the PTW period.

[0106] The present disclosure provides a method for monitoring paging messages, which is performed by user equipment 101. Referring to FIG. 4 , FIG. 4 is a diagram illustrating a method for monitoring paging messages according to an exemplary embodiment. As shown in FIG. 4 , the method includes steps S401 to S403, specifically:

[0107] Step S401: The user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception (e-DRX) cycle, wherein the first period includes a period corresponding to a paging time window (PTW) in the e-DRX cycle.

[0108] Step S402: After receiving the LP WUS, the main receiver switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment.

[0109] Step S403: During a period other than the first period in the e-DRX cycle, the user equipment 101 does not monitor the LP WUS and / or PO.

[0110] The execution order of step S403 is for illustration only and is not limiting. The operation of the user equipment 101 outside the PTW period may be before or after step S401.

[0111] In some possible implementations, the network device 102 does not schedule paging messages during periods outside of the PTW within the e-DRX cycle. Therefore, the user equipment 101 monitors the LP WUS using a low-power receiver during the first period. Upon detecting the LP WUS, the user equipment 101 monitors the PO using a primary receiver. However, the user equipment 101 does not monitor the LP WUS or the PO outside of the first period of the e-DRX cycle.

[0112] In the embodiment of the present disclosure, combined with the timing of the network device 102 scheduling the paging message, the user equipment 101 can still be in the sleep state during the period outside the PTW, and the low power receiver can stop monitoring the LP WUS, thereby further achieving energy saving.

[0113] The present disclosure provides a method for monitoring paging messages, which is performed by user equipment 101. The method includes steps S301 to S302, specifically:

[0114] In step S301 , the user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception e-DRX cycle.

[0115] Step S302: After receiving the LP WUS, the main receiver switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment.

[0116] The first time period includes: all time periods in the e-DRX cycle.

[0117] In some possible implementations, when the network device 102 has a scheduling paging requirement, it will first send an LP WUS to wake up the primary receiver of the user equipment 101 .

[0118] In some possible implementations, all time periods in the e-DRX cycle include: time periods corresponding to the PTW and time periods outside the PTW.

[0119] In this embodiment, the user equipment 101 monitors the LP WUS through the low power receiver during the period corresponding to the PTW and the period outside the PTW. If no LP WUS is monitored, the main receiver can remain in sleep mode during this period to save energy.

[0120] In this embodiment, in conjunction with the LP WUS mechanism, user equipment 101 utilizes a low-power receiver to monitor the LP WUS throughout the e-DRX cycle to determine whether a paging schedule is present. If no LP WUS is detected, the primary receiver of user equipment 101 may remain in a sleep state to save energy.

[0121] The present disclosure provides a method for monitoring paging messages, which is performed by user equipment 101. The method includes steps S301 to S302, specifically:

[0122] In step S301 , the user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception e-DRX cycle.

[0123] Step S302: After receiving the LP WUS, the main receiver switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment.

[0124] The first time period includes: a time period corresponding to the PTW and a time period corresponding to at least one listening window, wherein the listening window is used to monitor the LP WUS.

[0125] In some possible implementations, a listening window for listening to the LP WUS is defined.

[0126] In some possible implementations, the listening window may be defined by a protocol. For example, the protocol may define the time domain position and number of the listening window.

[0127] In some possible implementations, the listening window is configured by the network device 102. For example, the network device 102 configures the time domain position and number of the listening window.

[0128] In some possible implementations, at least one listening window is located in a period outside the PTW in the e-DRX cycle.

[0129] In one example, as shown in FIG. 7 , on the time axis, at least one listening window may be located in front of or behind the PTW, or may be configured on both sides of the PTW.

[0130] In this embodiment, configuring a listening window outside of the PTW can promptly meet the paging scheduling needs that may exist in network device 102 without having to wait until the PTW period, thereby shortening data transmission latency. During the listening window, if network device 102 has a paging scheduling need, it can first send an LP WUS to notify user equipment 101 to listen to the PO.

[0131] In the disclosed embodiment, user equipment 101 uses a low-power receiver to monitor the LP WUS during the period corresponding to the PTW and during the period corresponding to at least one listening window. This embodiment is applicable to scenarios where network device 102 requires paging scheduling outside of the PTW. Paging scheduling is performed using the configured listening window. User equipment 101 monitors the LP WUS during this listening window, without having to wait until the PTW period. This helps reduce data transmission latency while saving energy.

[0132] The present disclosure provides a method for monitoring paging messages, which is performed by user equipment 101. Referring to FIG5 , FIG5 is a diagram illustrating a method for monitoring paging messages according to an exemplary embodiment. As shown in FIG5 , the method includes steps S501 to S503, specifically:

[0133] Step S501 : The user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception e-DRX cycle.

[0134] The first time period includes: a time period corresponding to the PTW and a time period corresponding to at least one listening window, wherein the listening window is used to monitor the LP WUS.

[0135] Step S502 : After receiving the LP WUS, the main receiver of the user equipment 101 switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment 101 .

[0136] Step S503: During a period other than the first period in the e-DRX cycle, the user equipment 101 does not monitor the LP WUS and / or PO.

[0137] The execution order of step S503 is for illustration only and is not limiting. Depending on the distribution position of the first time period, step S503 may be executed before or after step S501.

[0138] In some possible implementations, the user equipment 101 may not monitor the LP WUS or the PO during periods other than the first period. Alternatively, the user equipment 101 monitors the LP WUS during periods other than the first period in the e-DRX cycle, and does not monitor the PO when no LP WUS is detected.

[0139] In some possible implementations, when there is a need to schedule paging, the network device 102 may first send an LP WUS to wake up the user equipment 101 .

[0140] In the embodiment of the present disclosure, when a listening window is configured, the user equipment 101 may monitor the LP WUS during the listening window and the period corresponding to the PTW, and no longer monitor the LP WUS during other periods of the e-DRX cycle, to achieve further energy saving.

[0141] The embodiment of the present disclosure provides a method for monitoring paging messages, which is executed by the user equipment 101. The method includes steps S500 to S503, specifically:

[0142] In step S500 , the user equipment 101 receives configuration information sent by the network device 102 , where the configuration information is used to configure at least one listening window.

[0143] Step S501 : The user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception e-DRX cycle.

[0144] The first time period includes: a time period corresponding to the PTW and a time period corresponding to at least one listening window, wherein the listening window is used to monitor the LP WUS.

[0145] Step S502 : After receiving the LP WUS, the main receiver of the user equipment 101 switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment 101 .

[0146] Step S503: During a period other than the first period in the e-DRX cycle, the user equipment 101 does not monitor the LP WUS and / or PO.

[0147] In some possible implementations, the network device 102 may send the configuration information via Radio Resource Control (RRC) signaling.

[0148] In some possible implementations, the configuration information includes at least one of the following:

[0149] The start time of at least one listening window;

[0150] The duration of at least one listening window;

[0151] The number of listening windows.

[0152] In this embodiment, the configuration information may indicate the start time (offset) of the listening window in each e-DRX cycle. The user equipment 101 may know the timing to start monitoring the LP WUS based on the start time of the listening window.

[0153] In this implementation, when there are multiple listening windows, the durations of the listening windows may be the same or different.

[0154] In this implementation, the number of listening windows may be greater than or equal to one.

[0155] In some possible implementations, the number of listening windows may also be defined by a protocol. For example, the protocol defines that there is only one listening window in a period outside the PTW of the e-DRX cycle.

[0156] In the disclosed embodiment, the user device 101 can obtain the monitoring window configured by the network device 102 according to the configuration information of the network device 102, so as to monitor the LP WUS in each monitoring window and monitor the corresponding PO in a timely manner while saving energy.

[0157] The present disclosure provides a method for monitoring paging messages, which is performed by user equipment 101. Referring to FIG. 6 , FIG. 6 is a diagram illustrating a method for monitoring paging messages according to an exemplary embodiment. As shown in FIG. 6 , the method includes steps S601 to S603, specifically:

[0158] Step S601: The user equipment 101 monitors a low power wake-up signal LP WUS via a low power receiver in a first period of an extended discontinuous reception e-DRX cycle.

[0159] Step S602 : After receiving the LP WUS, the main receiver of the user equipment 101 switches from the sleep state to the working state, and monitors the paging opportunity PO corresponding to the user equipment 101 .

[0160] In step S603, if the user equipment 101 does not receive the corresponding paging message after receiving the set duration of the LP WUS, the main receiver enters the sleep state and monitors the LP WUS through the low power receiver.

[0161] In some possible implementations, the first time period includes: a time period corresponding to a paging time window PTW in an e-DRX cycle.

[0162] In some possible implementations, the first time period includes: the entire time period in the e-DRX cycle.

[0163] In some possible implementations, the first time period includes: a time period corresponding to the PTW and a time period corresponding to at least one listening window, where the listening window is used to monitor the LP WUS.

[0164] In some possible implementations, within a set duration after receiving the LP WUS, the primary receiver is in an operating state to monitor the PO.

[0165] In some possible implementations, if the corresponding paging message is not received after receiving the LP WUS for a set duration, the main receiver may enter the sleep state again and monitor the LP WUS via the low power receiver.

[0166] In one example, if the corresponding paging message is not received after the set duration of the LP WUS is received, it indicates that the user equipment 101 may be mistakenly awakened.

[0167] In one example, if the corresponding paging message is not received after receiving the set duration of the LP WUS, it indicates that the monitoring configuration of the LP WUS does not match the PO configuration corresponding to the user equipment 101 .

[0168] In the embodiment of the present disclosure, when the user equipment 101 has not received the corresponding paging message after monitoring the LP WUS for a set period of time, the user equipment 101 can adjust the energy saving state in time and still use the low power receiver to monitor the LP WUS, so that the main receiver enters the sleep state to achieve energy saving.

[0169] The present disclosure provides a method for sending a paging message, which is executed by the network device 102. Referring to FIG. 8 , FIG. 8 is a diagram illustrating a method for sending a paging message according to an exemplary embodiment. As shown in FIG. 8 , the method includes step S801, specifically:

[0170] Step S801: In the first period of the e-DRX cycle, the network device 102 sends an LP WUS to the user equipment 101 before sending a paging message.

[0171] In some possible implementations, the e-DRX cycle may be configured to be between 20.48 s and 2.92 h.

[0172] In some possible implementations, the first time period may be the entire time period corresponding to the e-DRX cycle, or a portion of the time period therein.

[0173] In the embodiment of the present disclosure, during the e-DRX cycle, the network device 102 first sends an LP WUS to wake up the user equipment 101 before sending a paging message. The user equipment 101 can use a low-power receiver to monitor the LP WUS. Before receiving the LP WUS, the main receiver of the user equipment 101 can remain in a sleep state. This, combined with the LP WUS mechanism, further saves energy consumption of the user equipment 101 in the e-DRX scenario.

[0174] The present disclosure provides a method for sending a paging message, which is executed by the network device 102. The method includes steps S801 to S802, specifically:

[0175] Step S801: In the first period of the e-DRX cycle, the network device 102 sends an LP WUS to the user equipment 101 before sending a paging message.

[0176] Step S802: During a period other than the first period in the e-DRX cycle, no LP WUS and / or paging information is sent.

[0177] In some possible implementations, the paging information includes paging DCI and a paging message scheduled by the paging DCI.

[0178] In some possible implementations, the first time period may be the entire time period corresponding to the e-DRX cycle, or a portion of the time period therein.

[0179] In some possible implementations, the network device 102 does not send a paging message outside the first time period, nor does it need to send an LP WUS to wake up the user equipment 101. In this implementation, the user equipment 101 may not monitor the LP WUS and PO outside the first time period.

[0180] In some possible implementations, the user equipment 101 may monitor the LP WUS outside the first time period to obtain possible temporary scheduling in a timely manner, or may not monitor the LP WUS to further save energy consumption.

[0181] In the disclosed embodiment, the network device 102 schedules paging messages only in the first time period and sends LP WUS to wake up the user device 101 before sending the paging message. There is no need to wake up the user device 101 outside the first time period, which is beneficial to further energy saving of the network device 102.

[0182] In an embodiment of the present disclosure, a method for sending a paging message is provided, which is executed by a network device 102. The method includes step S801, or the method includes steps S801 to S802, wherein the first time period includes one of the following:

[0183] All periods in the e-DRX cycle;

[0184] The period corresponding to PTW in the e-DRX cycle;

[0185] The time period corresponding to the PTW and the time period corresponding to at least one listening window, wherein the listening window is used to monitor the LP WUS.

[0186] In some possible implementations, only one PTW is configured in one e-DRX cycle.

[0187] In some possible implementations, during the first time period, if the network device 102 has a need to schedule paging, it will first send an LP WUS. Before the user equipment 101 receives the LP WUS, it can keep the main receiver in a sleep state to save energy.

[0188] In some possible implementations, outside the first time period, the network device 102 may not perform paging scheduling, and the user equipment 101 may keep the primary receiver in a sleep state to save energy.

[0189] In some possible implementations, at least one listening window is located in a period outside the PTW in the e-DRX cycle.

[0190] In one example, as shown in FIG. 7 , on the time axis, at least one listening window may be located in front of or behind the PTW, or may be configured on both sides of the PTW.

[0191] In this embodiment, configuring a listening window outside of the PTW can promptly meet the paging scheduling needs that may exist in network device 102 without having to wait until the PTW period, thereby shortening data transmission latency. During the listening window, if network device 102 has a paging scheduling need, it can first send an LP WUS to notify user equipment 101 to listen to the PO.

[0192] In some possible implementations, the method may further include the following step S800, wherein:

[0193] In step S800 , the network device 102 sends configuration information to the user equipment 101 , where the configuration information is used to configure at least one listening window.

[0194] Here, step S800 may be performed before step S801.

[0195] In some possible implementations, the configuration information includes at least one of the following:

[0196] The start time of at least one listening window;

[0197] The duration of at least one listening window;

[0198] The number of listening windows.

[0199] In this embodiment, the network device 102 notifies the user equipment 101 of the timing to monitor the LP WUS through configuration information, so that the user equipment 101 can monitor the LP WUS at an appropriate location, thereby facilitating timely acquisition of its corresponding paging message while saving energy.
