Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and particularly relates to a communication method, device and readable storage medium. BACKGROUND

[0002] Low Power Wake Up Signal (LP WUS) is introduced in Release 18 (R18) of the 3rd Generation Partnership Project (3GPP). A User Equipment (UE) uses a separate Low Power Wake Up Receiver (LPWUR) to monitor the LP WUS. The UE needs to use a main receiver to normally process uplink and downlink data. If the UE receives the LP WUS and the LP WUS indicates to wake up, the UE will turn on the main receiver to process the uplink and downlink data. If the UE does not receive the LP WUS or the LP WUS indicates not to wake up, the UE will keep the main receiver in a sleep state, thereby achieving energy saving of the UE. SUMMARY

[0062] As Figure 1 As shown in FIG. 1, a communication method according to embodiments of the present disclosure can be applied to a wireless communication system 100, which can include a user equipment 101 and a network equipment 102. The user equipment 101 is configured to support carrier aggregation and can be connected to multiple carrier units of the network equipment 102, including a primary carrier unit and one or more secondary carrier units.

[0063] It should be understood that the above wireless communication system 100 can be applied to both low frequency scenarios and high frequency scenarios. The application scenarios of the wireless communication system 100 include, but are not limited to, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a worldwide interoperability for microwave access (WiMAX) communication system, a cloud radio access network (CRAN) system, a future 5th-Generation (5G) system, a new radio (NR) communication system, or a future evolved public land mobile network (PLMN) system, and the like.

[0064] The user equipment 101 shown above can 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, and the like. The user equipment 101 can have a wireless transceiving function, and can communicate (e.g., wirelessly communicate) with one or more network devices of one or more communication systems and receive network services provided by the network devices, where the network devices include, but are not limited to, the network device 102.

[0065] The user equipment (UE) 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, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, and the like.

[0066] The network device 102 can be an access network device (or an access network site). The access network device refers to a device having a network access function, such as a radio access network (RAN) base station and the like. The network device 102 can specifically include a base station (BS), or include a base station and a radio resource management device for controlling the base station, and the like. The network device 102 can also include a relay station (relay device), an access point, and a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, and the like. The network device 102 can be a wearable device or a vehicle-mounted device. The network device 102 can also be a communication chip with a communication module.

[0067] For example, the network device 102 includes, but is not limited to, a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in an LTE system, a radio network controller (RNC), a node B (NB) in a WCDMA system, a radio controller under a CRAN system, a base station controller (BSC), a base transceiver station (BTS) in a GSM system or a CDMA system, a home base station (for example, a home evolved node B, or a home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), or a mobile switching center, and the like.

[0068] If the user equipment 101 is configured in the LP WUS state, the user equipment 101 needs to solve the problem of how to determine the indication period of radio link monitoring (RLM) in order to save energy consumption of the main transceiver in the sleep state or the non-active time.

[0069] The embodiment of the present disclosure provides a communication method. Referring to Figure 2 , Figure 2 is a schematic diagram of a communication method according to an exemplary embodiment, as shown in Figure 2 , the method includes steps S201-S202, specifically:

[0070] At step S201, the network device 102 sends indication information to the user equipment, the indication information being used to indicate a first time length, wherein the first time length is used for the user equipment to determine a first period for evaluating the radio link quality in a state of being configured with the LP WUS.

[0071] In some possible implementation manners, the network device 102 can send the indication information through high layer signaling. For example, the high layer signaling is Radio Resource Control (RRC) signaling.

[0072] In some possible implementation manners, the first time length (T) can be a fixed value or contain multiple candidate values.

[0073] In an example, the network device 102 configures a first time length for multiple user equipments 101, and the first time length is a fixed value applicable to multiple RLM scenarios.

[0074] In another example, the network device 102 respectively configures corresponding first time lengths for different user equipments 101, for example, different terminal capability user equipments 101 are respectively configured with first time lengths.

[0075] In some possible implementation manners, the first time length can be related to an average period of sending the LP WUS by the network device 102 or an average period of sending downlink information by the network device 102.

[0076] In an example, the network device 102 determines by statistics that an LP WUS needs to be sent once every 80 ms to wake up the user equipment 101 to receive downlink data, and then the first time length can be configured as 80 ms or close to 80 ms.

[0077] At step S202, the user equipment 101 receives the indication information.

[0078] At step S203, the user equipment 101 determines a first period for evaluating the radio link quality according to the first time length in a state of being configured with the low power consumption wake-up signal (LP WUS).

[0079] In some possible implementation manners, the user equipment 101 can be a user equipment 101 in an RRC connected state. For example, the network device 102 configures time domain resources of the LP WUS for the user equipment 101.

[0080] In some possible implementation, the main transceiver of the user equipment 101 can receive downlink information and / or send uplink information when in the active time. In the scenario where the user equipment 101 is configured with the LP WUS, if the main transceiver of the user equipment 101 does not detect information corresponding to the terminal in a set time period, the main transceiver will enter the inactive time.

[0081] In the inactive time, the main transceiver does not monitor all or part of the downlink channel, for example, does not monitor the Physical Downlink Control Channel (PDCCH) channel, or does not monitor the downlink reference signal, etc.

[0082] In some possible implementation, when the main transceiver is in the inactive time, the user equipment 101 monitors the LP WUS through the low-power transceiver, and the state of the main transceiver in the inactive time can also be referred to as the energy-saving state or the sleep state.

[0083] In an example, when the user equipment 101 detects the LP WUS corresponding to the terminal and the LP WUS indicates to wake up, the user equipment 101 can wake up the main transceiver, i.e., the main transceiver enters the active time from the inactive time to perform the RLM.

[0084] In another example, when the main transceiver of the user equipment 101 is in the active time for a time period equal to the time period corresponding to the first period, the user equipment 101 can wake up the main transceiver to perform the RLM even if the LP WUS is not received.

[0085] In some possible implementation, the first period refers to the indication period for example. The user equipment 101 can perform the RLM on the primary cell (PCell) and the primary secondary cell (PScell).

[0086] For example, in the scenario where the discontinuous reception (DRX) mode is not configured, the RLM of the user equipment 101 can include the following process: the physical layer of the user equipment 101 evaluates the radio link quality once per indication period, such as evaluating the measurement result of the reference signal (RS) of the to-be-measured cell. The radio link quality can be evaluated according to the synchronization threshold (Q in ) and the out-of-synchronization threshold (Q out ) for the measurement result in a time period.

[0087] For another example, in the scenario of configuring the DRX mode, the RLM of the user equipment 101 can include the following process: the physical layer of the user equipment 101 evaluates the radio link quality once in each first period, which can be according to Q in and Q out The measurement result of the past period is evaluated.

[0088] In some possible implementation manners, the user equipment 101 can determine the first duration as the first period.

[0089] In some possible implementation manners, the user equipment 101 can determine the first period according to the first duration and the shortest period of the reference signal in the radio link monitoring (RLM). For example, the first period is the maximum value between the first duration and the shortest period of the reference signal.

[0090] In the scenario where the user equipment 101 is configured with the LP WUS, the first duration can be determined in different ways according to whether the user equipment 101 is also configured with the C-DRX, which can be described as follows.

[0091] It can be understood that the interaction process between the user equipment 101 and the network device 102 is only illustrative and not limiting, and in some implementation manners, the method of the embodiments of the present disclosure can not include step S201, for example, in the scenario where the first duration is defined by a protocol, which can be described in detail in the following embodiments.

[0092] In the embodiments of the present disclosure, in the state where the user equipment 101 is configured with the LP WUS, the user equipment 101 can determine the first period for evaluating the radio link quality according to the first duration, so that the user equipment 101 in the energy saving state can also determine the period for evaluating the radio link quality by using the method of the present disclosure, so that the user equipment 101 in the energy saving state can perform the RLM in time according to the first period.

[0093] The embodiments of the present disclosure provide a communication method, which is performed by the user equipment 101. Referring to Figure 3 , Figure 3 is a schematic diagram of a communication method according to an exemplary embodiment, as shown in Figure 3 , the method includes step S301, specifically:

[0094] In step S301, the user equipment 101 determines a first period for evaluating a radio link quality according to a first duration in a state where the user equipment 101 is configured with a low-power wake-up signal (LP WUS).

[0095] In some possible implementation manners, the first duration can be a fixed value or include multiple candidate values.

[0096] In some possible implementation manners, the user equipment 101 can determine that the first period is equal to the first time length.

[0097] In some possible implementation manners, the step S301 can include the following step: the user equipment 101 determines the first period according to the first time length and the shortest period of the reference signal in the radio link monitoring (RLM).

[0098] In some possible implementation manners, the network device 102 can pre-configure the time domain resource of the RS for the RLM for the user equipment 101.

[0099] In an example, the network device 102 can configure a plurality of RSs, each of which corresponds to a set of time domain resources, such as each of which corresponds to its own transmission period. The first period is the minimum value in the transmission periods corresponding to the plurality of RSs.

[0100] In some possible implementation manners, the user equipment 101 can determine the maximum value between the first time length and the shortest period of the reference signal in the RLM as the first period.

[0101] In some possible implementation manners, in the state of being configured with the LP WUS, the main transceiver of the user equipment 101 can be in the inactive period, and the user equipment 101 listens to the LP WUS through the low-power receiver when the main transceiver is in the energy-saving state or the sleep state in the inactive period.

[0102] In some possible implementation manners, the first period refers to an indication period. The physical layer of the user equipment 101 evaluates the radio link quality, such as the measurement result of the reference signal of the cell to be measured, once in each first period. The radio link quality can be determined according to Q in and Q out The measurement result in the past period is evaluated.

[0103] In some possible implementation manners, the user equipment 101 can be configured or not configured with the connected discontinuous reception (C-DRX), and the first time length has different determination manners in the two scenarios, which can be described in detail in the following embodiments.

[0104] In the embodiments of the present disclosure, in the state of being configured with the LP WUS, the user equipment 101 can determine the first period for evaluating the radio link quality according to the first time length, so that the user equipment 101 in the energy-saving state can also determine the period for evaluating the radio link quality by using the method of the present disclosure, so that the user equipment 101 in the energy-saving state can perform the RLM in time according to the first period.

[0105] The embodiment of the disclosure provides a communication method, which is executed by the user equipment 101. Referring to Figure 4 , Figure 4 is a schematic diagram of a communication method according to an exemplary embodiment, as shown in Figure 4 The method comprises steps S401-S402, and specifically:

[0106] In step S401, the user equipment 101 receives indication information sent by the network device, and the indication information is used to indicate a first time length.

[0107] In some possible implementation manners, the user equipment 101 can not be configured with C-DRX.

[0108] In some possible implementation manners, the network device 102 can send the indication information through high-layer signaling. For example, the high-layer signaling is RRC signaling.

[0109] In some possible implementation manners, the first time length is related to an average period of sending LP WUS by the network device 102, or the first period is related to an average period of sending downlink information by the network device.

[0110] In an example, the network device 102 determines by statistics that an LP WUS needs to be sent once every 80 ms to wake up the user equipment 101 to receive downlink data, and the first time length can be configured as 80 ms or close to 80 ms.

[0111] In some possible implementation manners, the network device 102 can indicate a first time length applicable to a plurality of user equipment 101, or the network device 102 corresponds to a terminal capability of the user equipment 101.

[0112] In step S402, the user equipment 101 determines a first period for evaluating a radio link quality according to the first time length in a state of being configured with a low-power wake-up signal LP WUS.

[0113] The implementation manner of step S402 can refer to the description of step S301 in the foregoing embodiment, and details are not described herein again. For example, the user equipment 101 can also determine the first period according to the first time length and a shortest period of a reference signal in RLM.

[0114] In the embodiment of the disclosure, when the user equipment 101 is only configured with the LP WUS function and is not configured with C-DRX, the user equipment 101 can obtain the first time length configured by the network device 102 according to the indication information sent by the network device 102, and determine the first period for evaluating the radio link quality.

[0115] The embodiment of the disclosure provides a communication method, which is executed by a user equipment 101. The method comprises the following steps S301, in particular:

[0116] In step S301, the user equipment 101 determines a first period for evaluating the radio link quality according to a first time length in a state configured with a low-power wake-up signal (LP WUS).

[0117] The first time length is defined by a protocol.

[0118] In some possible implementation manners, the user equipment 101 can further determine the first period according to the first time length and a shortest period of a reference signal in the RLM.

[0119] In some possible implementation manners, the user equipment 101 can be not configured with C-DRX.

[0120] In some possible implementation manners, the protocol can define a value of the first time length or a determination manner of the first time length.

[0121] In some possible implementation manners, the first time length can be applicable to a plurality of user equipment 101, or the protocol defines the first time length corresponding to user equipment 101 with different terminal capabilities.

[0122] In some possible implementation manners, the first time length comprises N candidate values, and the N candidate values correspond to N different terminal capabilities respectively, where N is greater than or equal to 1.

[0123] In an example, the terminal capability is used to indicate a transition time length of the user equipment 101 from a state of sleeping by a main transceiver or listening to the LP WUS by a low-power transceiver to a state of waking up the main transceiver to receive data.

[0124] In an example, as shown in Table 1, the protocol can define the first time length for user equipment 101 with different terminal capabilities respectively. Wherein, the longer the transition time length is, the weaker the terminal capability is, and the longer the first time length is; the shorter the transition time length is, the stronger the terminal capability is, and the shorter the first time length is.

[0125] Table 1

[0126] Terminal capability First duration First capability 80 ms Second capability 160 ms …… …… Nth capability [TA N ms]]>

[0127] For example, as shown in Table 1, the user equipment 101 with the first capability has a strong terminal capability, and the first time length T1 is 80 ms. The user equipment 101 with the second capability has a weaker terminal capability than the first capability, and the second time length is greater than the first time length, which is 160 ms. In this example, the Nth capability is not limited to be stronger or weaker than the first or second capability, and the T N range can be adaptively defined according to the strength of the capability.

[0128] In some possible implementation, the first duration is configured larger so that the user equipment 101 has sufficient time to perform state transition when the user equipment 101 needs a larger transition duration.

[0129] In the embodiments of the present disclosure, when the user equipment 101 is only configured with the LP WUS function and is not configured with the C-DRX, the user equipment 101 can determine the first duration corresponding to the terminal capability of the user equipment 101 according to the protocol definition, so as to determine the first period for evaluating the radio link quality.

[0130] The embodiments of the present disclosure provide a communication method, which is performed by the user equipment 101. The method comprises steps S300-10 and S301, and specifically:

[0131] In step S300-10, the user equipment 101 sends information indicating the terminal capability supported by the user equipment 101 to the network device 102.

[0132] In some possible implementation, the user equipment 101 can report the terminal capability by sending the capability information.

[0133] In an example, in combination with Table 1, the terminal capability of the user equipment 101 can be the first capability or the second capability, etc.

[0134] In some possible implementation, the terminal capability reported by the user equipment 101 can be referred to by the network device 102.

[0135] In an example, the network device 102 knows the first duration defined by the protocol according to the terminal capability.

[0136] In another example, the network device 102 configures the first duration according to the terminal capability.

[0137] In step S301, the user equipment 101 determines the first period for evaluating the radio link quality according to the first duration in a state configured with the low-power wake-up signal (LP WUS).

[0138] The first duration is defined by the protocol.

[0139] It can be understood that the implementation of step S301 can refer to the description of the foregoing embodiments, which will not be described here. For example, the user equipment 101 can also determine the first period according to the first duration and the shortest period of the reference signal in the RLM.

[0140] In some possible implementation, the first duration comprises N candidate values, and the N candidate values correspond to N different terminal capabilities respectively, wherein N is greater than or equal to 1.

[0141] In some possible implementation, in the way that the protocol defines the first duration, the real-time sequence of step S300-10 and step S301 is only illustrative, for example, step S301 can be performed first.

[0142] In the embodiments of the present disclosure, the user equipment 101 can report the terminal capability to the network device 102, so that the network device 102 can learn the first duration corresponding to the user equipment 101 according to the terminal capability, and can also learn the first period in which the user equipment 101 performs the radio link quality evaluation.

[0143] The embodiments of the present disclosure provide a communication method, which is performed by the user equipment 101. The method comprises steps S300-20 and S301, and specifically:

[0144] In step S300-20, the user equipment 101 receives the configuration information sent by the network device 102, and the configuration information is used to configure the terminal capability applied by the user equipment.

[0145] In some possible implementation, the network device 102 configures the terminal capability applicable to the user equipment 101. The user equipment 101 determines the first duration corresponding to the terminal capability in the protocol according to the terminal capability configured by the network device 102.

[0146] In some possible implementation, the method can further comprise step S300-10 before step S300-20. In this implementation, the network device 102 can configure the terminal capability applied by the user equipment 101 according to the terminal capability supported by the user equipment 101 reported by the user equipment 101.

[0147] It can be understood that the terminal capability configured by the network device 102 can be the same as the terminal capability supported by the user equipment 101, or one of the multiple terminal capabilities supported by the user equipment 101.

[0148] In step S301, the user equipment 101 determines the first period for evaluating the radio link quality according to the first duration in a state of being configured with the low-power wake-up signal (LP WUS).

[0149] The first duration is defined in the protocol.

[0150] It can be understood that the implementation of step S301 can refer to the description of the foregoing embodiments, which will not be described here. For example, the user equipment 101 can further determine the first period according to the first duration and the shortest period of the reference signal in the RLM.

[0151] In some possible implementation, the first duration comprises N candidate values, and the N candidate values correspond to N different terminal capabilities respectively, wherein N is greater than or equal to 1.

[0152] In this embodiment of the disclosure, user equipment 101 can determine the first duration corresponding to the terminal capability defined in the protocol based on the terminal capability configured in network equipment 102, and perform RLM in a timely manner.

[0153] This disclosure provides a communication method, which is executed by a user equipment 101. The method includes step S301, specifically:

[0154] In step S301, the user equipment 101, while configured with the low-power wake-up signal LP WUS, determines the first period for evaluating the wireless link quality based on the first duration.

[0155] If user equipment 101 is configured to receive C-DRX discontinuously in connected state, the first duration is the period of C-DRX.

[0156] In some possible implementations, network device 102 may pre-configure C-DRX time-domain resources for user equipment 101. For example, network device 102 may indicate at least one of the following: C-DRX period, initial offset value, duration of onduration, and duration of offduration.

[0157] In some possible implementations, such as Figure 5 As shown in Figure 6, each C-DRX cycle includes a working period and a rest period.

[0158] In some possible implementations, the method may also include steps S302-10 or S302-20.

[0159] In one example, the method includes steps S301 and S302-10, wherein:

[0160] In step S302-10, when user equipment 101 receives LP WUS during the C-DRX working period, it switches from the LP WUS listening state to the master transceiver data transmission and reception state and performs RLM.

[0161] In this example, as Figure 5 As shown, during the C-DRX operating period, if user equipment 101 does not receive LP WUS, user equipment 101 can still maintain a low-power transceiver listening state for LP WUS. At this time, the main transceiver is still in an inactive period or in a sleep state. For example, during the t0 to t1 period of the operating period, although user equipment 101 is in the C-DRX operating period, it has not yet received an LP WUS indicating that the terminal should wake up. Therefore, the main transceiver of user equipment 101 can still remain in a sleep state and not listen to PDCCH, but listen to LP WUS through the low-power transceiver.

[0162] After receiving the LP WUS at time t1, the main transceiver of user equipment 101 will be woken up to perform normal data transmission and reception, such as listening to the PDCCH and / or downlink reference signal.

[0163] In another example, the method includes steps S301 and S302-20, wherein:

[0164] In steps S302-20, when user equipment 101 receives LP WUS before the C-DRX working period, it switches to the master transceiver data transmission and reception state at the start time of the C-DRX working period and performs RLM.

[0165] In this example, as Figure 6 As shown, if user equipment 101 receives an LPWUS indicating that it should wake up before the working period, for example, if user equipment 101 receives an LPWUS at time t0' before time t0, then user equipment 101 can wake up completely at the start time t0 of the working period, that is, switch to a normal data transmission and reception state, such as listening to PDCCH and / or downlink reference signals. However, if no LPWUS is heard before the working period, or if the LPWUS indicates that it should not wake up, such as if the LPWUS heard at time t2' indicates that it should not wake up, then the working period t2~t3 can not be started, that is, the master transceiver can remain in an inactive period during the period t2~t3.

[0166] The interval between the time when network device 102 sends LP WUS and the start time of the working period can be pre-configured by network device 102.

[0167] In the two examples above, the RLM process performed by user equipment 101 may include: the physical layer of user equipment 101 evaluating the radio link quality once per first cycle. For example, in the master transceiver wake-up state, user equipment 101 receives and measures the reference signal of the cell to be measured during the first time period to obtain the measurement result. User equipment 101 then calculates the RLM result based on the Q signal. in and Q out The measurement results were evaluated.

[0168] In one example, the measurement result may be at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).

[0169] In the scenario where the user equipment 101 is configured with the LP WUS function and the C-DRX, the user equipment 101 can determine the first time length according to the period of the C-DRX, and determine the first period according to the first time length, so as to perform the RLM in time.

[0170] The embodiment of the present disclosure provides a communication method, which is performed by the network device 102. Referring to Figure 7 , Figure 7 is a schematic diagram of a communication method according to an exemplary embodiment, as shown in Figure 7 , the method comprises the following steps S701, in particular:

[0171] In step S701, the network device 102 sends indication information to the user equipment 101, and the indication information is used to indicate a first time length, wherein the first time length is used by the user equipment to determine a first period for evaluating the radio link quality in a state where the LP WUS is configured.

[0172] In some possible implementation manners, the network device 102 can send the indication information through high-layer signaling. For example, the high-layer signaling is RRC signaling.

[0173] In some possible implementation manners, the first time length is related to an average period of sending the LP WUS by the network device 102, or the first period is related to an average period of sending the downlink information by the network device.

[0174] In an example, the network device 102 determines by statistics that the LP WUS needs to be sent once every 80 ms to wake up the user equipment 101 to receive the downlink data, and then the first time length can be configured as 80 ms or close to 80 ms.

[0175] In some possible implementation manners, the network device 102 can indicate one first time length applicable to multiple user equipment 101, or the network device 102 corresponds to the terminal capability of the user equipment 101.

[0176] In some possible implementation manners, the user equipment 101 determines the first period for evaluating the radio link quality according to the first time length in a state of listening to the LP WUS. For example, the first time length is determined as the first period; or the user equipment 101 can also determine the maximum value between the first time length and the shortest period of the reference signal in the RLM as the first period.

[0177] In some possible implementation manners, the first period refers to an indication period. The physical layer of the user equipment 101 evaluates the radio link quality once every first period, for example, evaluates the measurement result of the reference signal of the to-be-measured cell. The radio link quality can be determined according to the Q inand Q out The measurement result of the past time period is evaluated.

[0178] In some possible implementation manners, the first period is a first duration, or the first period is a maximum value between the first duration and a shortest period of a reference signal in the RLM.

[0179] In some possible implementation manners, in a scenario where the user equipment 101 is not configured with C-DRX, the first duration can be configured by the network device 102 through the indication information. Or, in other implementation manners, the first duration can also be defined by a protocol.

[0180] In some possible implementation manners, in a scenario where the user equipment 101 is configured with C-DRX, the first duration can be a period of the C-DRX.

[0181] In the embodiments of the present disclosure, the network device 102 can issue indication information to the user equipment 101 to inform the user equipment 101 of the first duration. Thus, the user equipment 101 in the state of listening to the LP WUS can determine the first period for evaluating the radio link quality according to the first duration, so that the user equipment 101 in the power saving state can perform the RLM in time according to the first period.

[0182] The embodiments of the present disclosure provide a communication method, which is performed by the network device 102. The method comprises steps S700-10 and S701, and specifically:

[0186] In some possible implementation manners, in a manner of defining the first duration by a protocol, the implementation sequence of step S300-10 and step S301 is only illustrative, for example, step S301 can also be performed first.

[0187] In some possible implementation manners, in a manner of defining the first duration by a protocol, the network device 102 can obtain the first duration corresponding to the user equipment 101 defined by the protocol according to the terminal capabilities reported by the user equipment 101.

[0188] In some possible implementation, in the manner that the network device 102 configures the first time length, the network device 102 can configure the corresponding first time length according to the terminal capability of the user equipment 101.

In this implementation, the network device 102 can configure the terminal capability applied by the user equipment 101 according to the terminal capability supported by the user equipment 101 reported by the user equipment 101.

[0198] It can be understood that the terminal capability configured by the network device 102 can be the same as the terminal capability supported by the user equipment 101, or one of the multiple terminal capabilities supported by the user equipment 101.

[0199] In some possible implementation, the first duration is defined by a protocol.
