[0002] In order to save energy for user equipment (UE), a discontinuous reception (DRX) mechanism is introduced. The network equipment configures the DRX configuration for the UE, and the UE uses the DRX configuration to monitor the physical downlink control channel (PDCCH), and then receives the physical downlink shared channel (PDSCH) or sends the physical uplink shared channel (PUSCH) according to the monitored PDCCH.

Currently, the network device only configures one value of the DRX timer in the DRX configuration, and the UE will also use a fixed value of the DRX timer.

[0041] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0042] The UE can use the DRX mechanism to achieve energy saving. The DRX on the UE side includes DRX in the connected state (Conncted-DRX, C-DRX) and DRX in the idle state. The C-DRX on the UE side is described below.

[0043] The network device can configure C-DRX for the UE through dedicated radio resource control (RRC) signaling, so that the UE monitors the PDCCH discontinuously to achieve the purpose of UE power saving. As an example, the configuration parameters related to C-DRX are:

[0044] -DRX state timer (drx-onDurationTimer): used to determine a period of time after the start of the DRX cycle, which is called the DRX wake-up period or DRX On Duration (also referred to as On Duration);

[0045] -DRX slot offset (drx-SlotOffset): used to determine the delay before starting the DRX state timer;

[0046] -DRX-InactivityTimer: used to determine the period of time after a PDCCH opportunity (PDCCH Hoccasion), in which a PDCCH is detected and indicates a new uplink or downlink transmission;

[0047] - Downlink DRX retransmission timer (drx-RetransmissionTimerDL): used to determine the maximum time before receiving a downlink retransmission;

[0048] - Uplink DRX retransmission timer (drx-RetransmissionTimerUL): used to determine the maximum time before receiving an uplink retransmission grant;

[0049] -DRX long cycle start offset (drx-LongCycleStartOffset): used to determine the DRX long cycle (drx-LongCycle) and the DRX start offset (drx-StartOffset), wherein drx-StartOffset is used to determine the start time of the DRX long cycle and the DRX short cycle (e.g., the subframe corresponding to the start time);

[0050] -DRX short cycle (drx-ShortCycle): It is an optional configuration and is used to determine the DRX short cycle;

[0051] -DRX short cycle timer (drx-ShortCycleTimer): It is an optional configuration and is used to determine the duration of the DRX short cycle. Its value refers to the multiple of the DRX short cycle.

[0052] - Downlink DRX HARQ RTT timer (drx-HARQ-RTT-TimerDL): the minimum duration before a downlink allocation for HARQ retransmission expected by the MAC entity;

[0053] - Uplink DRX HARQ RTT timer (drx-HARQ-RTT-TimerUL): The minimum duration before an uplink grant for HARQ retransmission expected by the MAC entity.

[0054] In the above solution, the unit of the DRX parameter is millisecond (ms), which is applicable to services whose transmission period is an integer multiple of the ms period.

[0055] In the above solution, the downlink DRX retransmission timer, the uplink DRX retransmission timer, the downlink DRX HARQ RTT timer, and the uplink DRX HARQ RTT timer are related to HARQ.

[0056] If the UE is configured with DRX, the UE needs to monitor the PDCCH during the DRX active time. The DRX active time includes the following situations:

[0057] 1) The operation period of any one of the five timers, drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL and ra-ContentionResolutionTimer, belongs to the DRX activation period.

[0058] 2) After the UE sends a scheduling request (SR) on a physical uplink control channel (PUCCH), the period during which the SR is in a pending state belongs to the DRX activation period.

[0059] 3) In the contention-based random access process, the period during which the UE has not received an initial transmission indicated by the C-RNTI-scrambled PDCCH after successfully receiving the random access response belongs to the DRX activation period.

[0060] The UE determines the start time of drx-onDurationTimer according to whether the current DRX cycle is a short DRX cycle or a long DRX cycle. The specific regulations are as follows:

[0061] 1.1> If DRX short cycle is used, the SFN and subframe number of the start time of drx-onDurationTimer satisfy: [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle);

[0062] 1.2> If the DRX long cycle is used, the SFN and subframe number of the start time of drx-onDurationTimer satisfy: [(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset;

[0063] 2> Start drx-onDurationTimer at the moment when the start time of the subframe determined by the above formula is shifted back by drx-SlotOffset time slots.

[0064] The conditions for the UE to start or restart the drx-InactivityTimer are:

[0065] If the UE receives a PDCCH (or DCI) indicating an initial downlink or uplink transmission, the UE starts or restarts the drx-InactivityTimer.

[0066] The conditions for the UE to start and stop drx-RetransmissionTimerDL are:

[0067] When the UE receives a PDCCH indicating a downlink transmission, or when the UE receives a MAC PDU on the configured downlink grant resources, the UE stops the drx-RetransmissionTimerDL corresponding to the HARQ process. The UE starts the drx-HARQ-RTT-TimerDL corresponding to the HARQ process after completing the transmission of the HARQ process feedback for this downlink transmission.

[0068] If the drx-HARQ-RTT-TimerDL corresponding to a HARQ process of the UE times out, and the decoding of the downlink data transmitted using this HARQ process is unsuccessful, the UE starts the drx-RetransmissionTimerDL corresponding to this HARQ process.

[0069] The conditions for the UE to start and stop drx-RetransmissionTimerUL are:

[0070] When the UE receives a PDCCH indicating an uplink transmission, or when the UE sends a MAC PDU on the configured uplink grant resources, the UE stops the drx-RetransmissionTimerUL corresponding to the HARQ process. The UE starts the drx-HARQ-RTT-TimerUL corresponding to the HARQ process after completing the first repetition of the PUSCH.

[0071] If the drx-HARQ-RTT-TimerUL corresponding to a HARQ process of the UE times out, the UE starts the drx-RetransmissionTimerUL corresponding to this HARQ process.

[0072] From the above DRX mechanism, it can be seen that after completing uplink transmission or completing ACK / NACK feedback for downlink transmission, the UE will first start a DRX HARQ RTT timer (drx-HARQ-RTT-TimerUL for uplink transmission and drx-HARQ-RTT-TimerDL for downlink transmission). The UE is in a dormant state during the operation of the DRX HARQ RTT timer and does not monitor the PDCCH. The UE starts to monitor the uplink retransmission scheduling after the timer expires or determines whether to start monitoring the downlink retransmission scheduling based on the feedback.

[0073] like Figure 2 As shown in the figure, the DRX cycle consists of "On Duration" and "DRX opportunity (Opportunity for DRX)", wherein, during the On Duration time, the UE is in the DRX active state; if the terminal does not receive the PDCCH during the On Duration time, it will stop monitoring and switch to the DRX inactive time (DRX inactive time) during the "Opportunity for DRX" time, and the UE does not receive the PDCCH to reduce power consumption (that is, the UE is in a sleep period).

[0074] The start time of the DRX cycle (that is, the start time of the On Duration) can be determined using the following formula:

[0075] [(SFN*10)+subframe number]modulo(current DRX)=drx-StartOffset;

[0076] Among them, SFN represents the system frame number corresponding to the start time of the DRX cycle, subframe number represents the subframe number corresponding to the start time of the cycle, current DRX represents the current DRX cycle, which can be a DRX long cycle (drx-LongCycle) or a DRX short cycle (drx-ShortCycle), drx-StartOffset represents the DRX start offset (drx-StartOffset), and modulo is the remainder operation.

[0077] Network devices can also use energy-saving mechanisms to achieve the purpose of energy saving. The energy-saving mechanism on the network device side is called cell DTX / DRX, where DTX stands for discontinuous transmission and DRX stands for discontinuous reception. In other words, network devices also have an active period and a non-active period. During the active period, the network device is in an active state and can send / receive data; during the non-active period, the network device is in a dormant state and only sends some common signals to achieve energy saving. When the network device enters the non-active period, whether the network device is scheduled is determined by the network device implementation.

[0078] Currently, the network device only configures one value of the DRX timer in the DRX configuration of the UE, and the UE will also use a fixed value of the DRX timer. If the value of the DRX timer is too large, the UE's energy consumption will be high. If the value of the DRX timer is too small, the UE's transmission reliability will be low.

[0079] For example: Figure 3 As shown, when cell DTX / DRX and UE DRX (i.e., C-DRX) are configured together, the UE may trigger the DRX inactive timer or DRX retransmission timer to run due to new transmission or retransmission, and the UE will monitor the PDCCH to receive the scheduling of the network device before these DRX timers expire. However, when the network device enters the cell DTX / DRX inactive period, the network device may not schedule or the scheduling time may be much earlier than the end time of the UE's DRX inactive timer or DRX retransmission timer, which will cause additional power consumption of the UE. In addition, the purpose of introducing the UE's DRX inactive timer is to avoid missing the scheduling of the network device, so the value may be configured to be larger, and the DRX inactive timer will be restarted every time there is a new transmission, so the additional power consumption of the UE will be more obvious.

[0080] To this end, the following technical solutions of the embodiments of the present application are proposed. To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0081] Figure 4 This is a flow chart of the communication method provided in the embodiment of the present application. Figure 1 ,like Figure 4 As shown, the communication method includes:

[0082] Step 401: A UE receives first configuration information sent by a network device, where the first configuration information is used to configure at least one value of a DRX timer.

[0083] In the embodiment of the present application, the first configuration information is used to configure at least one value of the DRX timer. In some implementations, the first configuration information is used to configure multiple values ​​of the DRX timer.

[0084] In some implementations, the first configuration information is carried in RRC signaling. Exemplarily, the first configuration information is C-DRX configuration information, which is used to configure C-DRX. The understanding of C-DRX here can refer to the aforementioned related description. Exemplarily, the first configuration information is cell DTX / DRX configuration information, which is used to configure cell DTX / DRX, and the understanding of cell DTX / DRX can refer to the aforementioned related description.

[0085] In some implementations, the DRX timer configured by the first configuration information includes at least one of the following: a DRX inactivity timer and a DRX retransmission timer. Here, the understanding of the DRX inactivity timer and the DRX retransmission timer can refer to the above related description.

[0086] In some embodiments, the first configuration information is also used to configure a usage condition for each of at least one value of the DRX timer, where the usage condition is related to at least one of the following: whether the network device has an energy-saving function enabled and whether the network device is in an activation period.

[0087] In some implementations, the number of at least one value configured by the first configuration information is less than or equal to a first number, and the first number is specified by a protocol.

[0088] In some implementations, the UE sends a second signaling to the network device, the second signaling being used to indicate a second quantity supported or preferred by the UE, the second quantity being used by the network device to determine the quantity of at least one value configured by the first configuration information. Here, the second signaling may be, for example, UE capability information.

[0089] Exemplarily, taking the DRX timer as a DRX inactive timer as an example, the network device configures at least one value of the DRX inactive timer for the UE. Optionally, the network device further configures a use condition of at least one value of the DRX inactive timer, for example: whether a certain value of the DRX inactive timer is only available when the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether a certain value of the DRX inactive timer is only available when the network device is in an active period. In one implementation, for the case of configuring a DRX inactive timer with multiple values, the first value of the multiple values ​​is defaulted to be available in all cases, such as whether the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether the network device is in an active period or an inactive period, the first value of the DRX inactive timer is available. Among them, the maximum number of configurable values ​​for the DRX inactive timer may be specified by the protocol, and the number of values ​​actually configured by the network device may be less than or equal to the maximum number of configurable values ​​based on the protocol. In one case, the number of values ​​actually configured by the network device is determined by the network device implementation. In another case, the number of values ​​actually configured by the network device is determined according to the number reported by the UE that the UE supports or prefers. The UE may actively report the number supported or preferred by the UE to the network device, or the UE may report the number supported or preferred by the UE to the network device after receiving a request from the network device.

[0090] Exemplarily, taking the DRX timer as a DRX retransmission timer (such as a downlink DRX retransmission timer) as an example, the network device configures at least one value of the DRX retransmission timer for the UE. Optionally, the network device also configures a use condition of at least one value of the DRX retransmission timer, for example: whether a certain value of the DRX retransmission timer is only available when the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether a certain value of the DRX retransmission timer is only available when the network device is in an active period. In one implementation, for the case of configuring a DRX retransmission timer with multiple values, the first value of the multiple values ​​is defaulted to be available in all cases, such as whether the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether the network device is in an active period or an inactive period, the first value of the DRX retransmission timer is available. Among them, the maximum number of configurable values ​​of the DRX retransmission timer can be specified by the protocol, and the number of values ​​actually configured by the network device can be less than or equal to the maximum number of configurable values ​​based on the protocol. In one case, the number of values ​​actually configured by the network device is determined by the network device implementation. In another case, the number of values ​​actually configured by the network device is determined according to the number reported by the UE that the UE supports or prefers. The UE may actively report the number supported or preferred by the UE to the network device, or the UE may report the number supported or preferred by the UE to the network device after receiving a request from the network device.

[0091] Step 402: The UE receives a first signaling sent by a network device, and adjusts a value of a DRX timer or turns off the DRX timer based on the first signaling; wherein the UE is in an active period during the operation of the DRX timer.

[0092] In the embodiment of the present application, the first signaling adjusts the value of the DRX timer or turns off the DRX timer.

[0093] In some embodiments, the first signaling is downlink control information (Downlink Control Information, DCI). Exemplarily, the DRX timer is a DRX inactive timer, and the first signaling is a DCI for scheduling a new transmission. Here, the new transmission refers to a new uplink or downlink transmission. Exemplarily, the DRX timer is a DRX retransmission timer, and the first signaling is a DCI for scheduling a retransmission. Here, the retransmission refers to an uplink or downlink retransmission.

[0094] In some implementations, the first signaling includes at least one of the following information:

[0095] 1) First information, where the first information is used to indicate whether to adjust the value of the DRX timer.

[0096] Here, the first information is used to indicate whether to adjust the value of the DRX timer, which can also be understood as the first information is used to indicate whether to overwrite the configured value of the DRX timer.

[0097] Exemplarily, whether to adjust the value of the DRX timer is indicated by a specific bit in the DCI, the value of the specific bit is a first value (such as 1) used to indicate the adjustment of the value of the DRX timer, and the value of the specific bit is a second value (such as 0) used to indicate that the value of the DRX timer is not adjusted. After receiving the DCI, the UE determines whether to adjust the value of the DRX timer according to the indication of the DCI.

[0098] 2) Second information, where the second information is used to indicate a first value among at least one value, where the first value is used to adjust a value of the DRX timer.

[0099] Exemplarily, three values ​​of the DRX timer are configured through the above-mentioned first configuration information, which are value 1, value 2 and value 3. A value (i.e., the first value) configured by the above-mentioned first configuration information is indicated by a specific bit in the DCI, the value of the specific bit is the first value used to indicate the value 1, the value of the specific bit is the second value used to indicate the value 2, and the value of the specific bit is the third value used to indicate the value 3. The value of the specific bit can be understood as the index of the value. Alternatively, a value (i.e., the first value) configured by the above-mentioned first configuration information is indicated by a bitmap in the DCI, the bitmap is 100 for indicating the value 1, the bitmap is 010 for indicating the value 2, and the bitmap is 001 for indicating the value 3. After receiving the DCI, the UE determines the value to be adjusted of the DRX timer according to the indication of the DCI.

[0100] When the first signaling includes the first information and the second information, when the first information indicates to adjust the value of the DRX timer, the first value indicated by the second information is valid; when the first information indicates not to adjust the value of the DRX timer, the first value indicated by the second information is invalid.

[0101] When the first signaling does not include the first information but includes the second information, the first value indicated by the second information is valid.

[0102] 3) Third information, where the third information is used to indicate the validity period of the first value or to indicate the scheduling range to which the first value applies.

[0103] For example, the third information is used to indicate that the validity period of the first value indicated by the second information is M time domain units (such as M subframes), or M DRX cycles, or M milliseconds, etc.

[0104] For example: the third information is used to indicate that the scheduling range to which the first value indicated by the second information applies is the current scheduling; or, the third information is used to indicate that the scheduling range to which the first value indicated by the second information applies is the current scheduling and the subsequent M schedulings; or, the third information is used to indicate whether the scheduling range to which the first value indicated by the second information applies includes the subsequent M schedulings. In this case, the default scheduling range includes the current scheduling, that is, the third information is used to indicate whether the subsequent M schedulings adopt the same DRX timer value as the current scheduling.

[0105] In some embodiments, if the third information indicates that the value of the DRX timer for subsequent M schedulings is the same as the current scheduling, then the first information carried in the scheduling signaling (such as DCI) corresponding to the subsequent M schedulings indicates that the value of the DRX timer does not need to be adjusted, and / or the second information carried in the scheduling signaling (such as DCI) corresponding to the subsequent M schedulings indicates a default value (such as 0).

[0106] 4) Fourth information: The fourth information is used to indicate whether to use the second value indicated by the UE to adjust the value of the DRX timer.

[0107] In some implementations, the UE sends a third signaling to the network device, where the third signaling is used to indicate the second value that the UE expects or prefers. Optionally, the third signaling is also used to indicate the reason why the UE expects or prefers the second value.

[0108] Here, the third signaling may be a scheduling request (Scheduling Request, SR), or a signaling carrying a buffer status report (Buffer Status reporting, BSR), or UE auxiliary information.

[0109] Exemplarily, the UE reports the value of the DRX timer expected or preferred by the UE to the network device through a third signaling (such as SR or signaling carrying BSR or UE auxiliary information). Optionally, the UE carries the reason in the third signaling or the next signaling, such as the UE has a large amount of uplink data to send, or the UE needs continuous scheduling by the network, or the UE needs to extend the running time of the DRX timer, or the UE has power saving requirements, etc.

[0110] The network device indicates through the fourth information whether to use the second value indicated by the UE to adjust the value of the DRX timer.

[0111] 5) Fifth information: The fifth information is used to indicate whether to turn off the DRX timer.

[0112] Here, if the fifth information indicates to turn off the DRX timer, it means that the network device will no longer perform subsequent scheduling for the UE after completing the current scheduling (i.e., scheduling through the above-mentioned first signaling) for the UE. For example: the service cell of the network device enters or is about to enter the inactive period of cell DTX / DRX. In this case, after the network device schedules the new transmission of the UE through DCI, it will no longer perform subsequent scheduling for the UE. The network device carries the fifth information for indicating to turn off the DRX timer in the DCI. In this way, after the UE receives the DCI, it will not start or restart the DRX timer. If a DRX timer is currently running, it will turn off the DRX timer, thereby saving UE energy consumption.

[0113] In some embodiments, the method further comprises the following steps:

[0114] The UE dynamically adjusts the value of the DRX timer or turns off the DRX timer based on the indication of the first signaling, so that the value of the DRX timer is more flexible, which can avoid the high energy consumption of the UE due to the value of the DRX timer being too large, and can also avoid the low transmission reliability of the UE due to the value of the DRX timer being too small.

[0115] It should be noted that the above-mentioned adjustment of the DRX inactivity timer and the DRX retransmission timer can be configured and used at the same time, or can also be configured and used separately. If only one of the values ​​of the DRX inactivity timer or the DRX retransmission timer is configured, the value of the DRX inactivity timer or the DRX retransmission timer will not be dynamically adjusted.

[0116] Figure 5 This is a flow chart of the communication method provided in the embodiment of the present application. Figure 2 ,like Figure 5 As shown, the communication method includes:

[0117] Step 501: The network device sends first configuration information to the UE, where the first configuration information is used to configure at least one value of the DRX timer.

[0118] In the embodiment of the present application, the first configuration information is used to configure at least one value of the DRX timer. In some implementations, the first configuration information is used to configure multiple values ​​of the DRX timer.

[0119] In some implementations, the first configuration information is carried in RRC signaling. Exemplarily, the first configuration information is C-DRX configuration information, which is used to configure C-DRX. The understanding of C-DRX here can refer to the aforementioned related description. Exemplarily, the first configuration information is cell DTX / DRX configuration information, which is used to configure cell DTX / DRX, and the understanding of cell DTX / DRX can refer to the aforementioned related description.

[0120] In some implementations, the DRX timer configured by the first configuration information includes at least one of the following: a DRX inactivity timer and a DRX retransmission timer. Here, the understanding of the DRX inactivity timer and the DRX retransmission timer can refer to the above related description.

[0121] In some embodiments, the first configuration information is also used to configure a usage condition for each of at least one value of the DRX timer, where the usage condition is related to at least one of the following: whether the network device has an energy-saving function enabled and whether the network device is in an activation period.

[0122] In some implementations, the number of at least one value configured by the first configuration information is less than or equal to a first number, and the first number is specified by a protocol.

[0123] In some implementations, the network device receives a second signaling sent by the UE, the second signaling being used to indicate a second quantity supported or preferred by the UE, the second quantity being used by the network device to determine the quantity of at least one value configured by the first configuration information. Here, the second signaling may be, for example, UE capability information.

[0124] Exemplarily, taking the DRX timer as a DRX inactive timer as an example, the network device configures at least one value of the DRX inactive timer for the UE. Optionally, the network device further configures a use condition of at least one value of the DRX inactive timer, for example: whether a certain value of the DRX inactive timer is only available when the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether a certain value of the DRX inactive timer is only available when the network device is in an active period. In one implementation, for the case of configuring a DRX inactive timer with multiple values, the first value of the multiple values ​​is defaulted to be available in all cases, such as whether the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether the network device is in an active period or an inactive period, the first value of the DRX inactive timer is available. Among them, the maximum number of configurable values ​​for the DRX inactive timer may be specified by the protocol, and the number of values ​​actually configured by the network device may be less than or equal to the maximum number of configurable values ​​based on the protocol. In one case, the number of values ​​actually configured by the network device is determined by the network device implementation. In another case, the number of values ​​actually configured by the network device is determined according to the number reported by the UE that the UE supports or prefers. The UE may actively report the number supported or preferred by the UE to the network device, or the UE may report the number supported or preferred by the UE to the network device after receiving a request from the network device.

[0125] Exemplarily, taking the DRX timer as a DRX retransmission timer (such as a downlink DRX retransmission timer) as an example, the network device configures at least one value of the DRX retransmission timer for the UE. Optionally, the network device also configures a use condition of at least one value of the DRX retransmission timer, for example: whether a certain value of the DRX retransmission timer is only available when the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether a certain value of the DRX retransmission timer is only available when the network device is in an active period. In one implementation, for the case of configuring a DRX retransmission timer with multiple values, the first value of the multiple values ​​is defaulted to be available in all cases, such as whether the network device turns on the energy saving function (i.e., turns on cell DTX / DRX), or whether the network device is in an active period or an inactive period, the first value of the DRX retransmission timer is available. Among them, the maximum number of configurable values ​​of the DRX retransmission timer can be specified by the protocol, and the number of values ​​actually configured by the network device can be less than or equal to the maximum number of configurable values ​​based on the protocol. In one case, the number of values ​​actually configured by the network device is determined by the network device implementation. In another case, the number of values ​​actually configured by the network device is determined according to the number reported by the UE that the UE supports or prefers. The UE may actively report the number supported or preferred by the UE to the network device, or the UE may report the number supported or preferred by the UE to the network device after receiving a request from the network device.

[0126] Step 502: The network device sends a first signaling to the UE, where the first signaling is used to instruct the UE to adjust the value of the DRX timer or turn off the DRX timer; wherein the UE is in an active period during the operation of the DRX timer.

[0127] In the embodiment of the present application, the first signaling adjusts the value of the DRX timer or turns off the DRX timer.

[0128] In some embodiments, the first signaling is a DCI. Exemplarily, the DRX timer is a DRX inactive timer, and the first signaling is a DCI for scheduling a new transmission. Here, the new transmission refers to a new uplink or downlink transmission. Exemplarily, the DRX timer is a DRX retransmission timer, and the first signaling is a DCI for scheduling a retransmission. Here, the retransmission refers to an uplink or downlink retransmission.

[0129] In some implementations, the first signaling includes at least one of the following information:

[0130] 1) First information, where the first information is used to indicate whether to adjust the value of the DRX timer.

[0131] Here, the first information is used to indicate whether to adjust the value of the DRX timer, which can also be understood as the first information is used to indicate whether to overwrite the configured value of the DRX timer.

[0132] Exemplarily, whether to adjust the value of the DRX timer is indicated by a specific bit in the DCI, the value of the specific bit is a first value (such as 1) used to indicate the adjustment of the value of the DRX timer, and the value of the specific bit is a second value (such as 0) used to indicate that the value of the DRX timer is not adjusted. After receiving the DCI, the UE determines whether to adjust the value of the DRX timer according to the indication of the DCI.

[0133] 2) Second information, where the second information is used to indicate a first value among at least one value, where the first value is used to adjust a value of the DRX timer.

[0134] Exemplarily, three values ​​of the DRX timer are configured through the above-mentioned first configuration information, which are value 1, value 2 and value 3. A value (i.e., the first value) configured by the above-mentioned first configuration information is indicated by a specific bit in the DCI, the value of the specific bit is the first value used to indicate the value 1, the value of the specific bit is the second value used to indicate the value 2, and the value of the specific bit is the third value used to indicate the value 3. The value of the specific bit can be understood as the index of the value. Alternatively, a value (i.e., the first value) configured by the above-mentioned first configuration information is indicated by a bitmap in the DCI, the bitmap is 100 for indicating the value 1, the bitmap is 010 for indicating the value 2, and the bitmap is 001 for indicating the value 3. After receiving the DCI, the UE determines the value to be adjusted of the DRX timer according to the indication of the DCI.

[0135] When the first signaling includes the first information and the second information, when the first information indicates to adjust the value of the DRX timer, the first value indicated by the second information is valid; when the first information indicates not to adjust the value of the DRX timer, the first value indicated by the second information is invalid.

[0136] When the first signaling does not include the first information but includes the second information, the first value indicated by the second information is valid.

[0137] 3) Third information, where the third information is used to indicate the validity period of the first value or to indicate the scheduling range to which the first value applies.

[0138] For example, the third information is used to indicate that the validity period of the first value indicated by the second information is M time domain units (such as M subframes), or M DRX cycles, or M milliseconds, etc.

[0139] For example: the third information is used to indicate that the scheduling range to which the first value indicated by the second information applies is the current scheduling; or, the third information is used to indicate that the scheduling range to which the first value indicated by the second information applies is the current scheduling and the subsequent M schedulings; or, the third information is used to indicate whether the scheduling range to which the first value indicated by the second information applies includes the subsequent M schedulings. In this case, the default scheduling range includes the current scheduling, that is, the third information is used to indicate whether the subsequent M schedulings adopt the same DRX timer value as the current scheduling.

[0140] In some embodiments, if the third information indicates that the value of the DRX timer for subsequent M schedulings is the same as the current scheduling, then the first information carried in the scheduling signaling (such as DCI) corresponding to the subsequent M schedulings indicates that the value of the DRX timer does not need to be adjusted, and / or the second information carried in the scheduling signaling (such as DCI) corresponding to the subsequent M schedulings indicates a default value (such as 0).

[0141] 4) Fourth information: The fourth information is used to indicate whether to use the second value indicated by the UE to adjust the value of the DRX timer.

[0142] In some implementations, the network device receives a third signaling sent by the UE, where the third signaling is used to indicate the second value that the UE expects or prefers. Optionally, the third signaling is also used to indicate the reason why the UE expects or prefers the second value.

[0143] Here, the third signaling may be SR, or signaling carrying BSR, or UE assistance information.

[0144] Exemplarily, the UE reports the value of the DRX timer expected or preferred by the UE to the network device through a third signaling (such as SR or signaling carrying BSR or UE auxiliary information). Optionally, the UE carries the reason in the third signaling or the next signaling, such as the UE has a large amount of uplink data to send, or the UE needs continuous scheduling by the network, or the UE needs to extend the running time of the DRX timer, or the UE has power saving requirements, etc.

[0145] The network device indicates through the fourth information whether to use the second value indicated by the UE to adjust the value of the DRX timer.

[0146] 5) Fifth information: The fifth information is used to indicate whether to turn off the DRX timer.

[0147] Here, if the fifth information indicates to turn off the DRX timer, it means that the network device will no longer perform subsequent scheduling for the UE after completing the current scheduling (i.e., scheduling through the above-mentioned first signaling) for the UE. For example: the service cell of the network device enters or is about to enter the inactive period of cell DTX / DRX. In this case, after the network device schedules the new transmission of the UE through DCI, it will no longer perform subsequent scheduling for the UE. The network device carries the fifth information for indicating to turn off the DRX timer in the DCI. In this way, after the UE receives the DCI, it will not start or restart the DRX timer. If a DRX timer is currently running, it will turn off the DRX timer, thereby saving UE energy consumption.

[0148] It should be noted that the above-mentioned adjustment of the DRX inactivity timer and the DRX retransmission timer can be configured and used at the same time, or can also be configured and used separately. If only one of the values ​​of the DRX inactivity timer or the DRX retransmission timer is configured, the value of the DRX inactivity timer or the DRX retransmission timer will not be dynamically adjusted.

[0149] The technical solution of the embodiment of the present application is illustrated below in conjunction with a specific application example. In the following application example, the DRX inactivation timer is used as an example for illustration.

[0150] Figure 3 This is a schematic diagram of UE C-DRX corresponding to the case where the value of the DRX inactivity timer is not adjusted. For the convenience of comparison, Figure 3 Cell DTX / DRX is also illustrated. During the Cell DTX / DRX activation period, the network device is in an activated state, and during the Cell DTX / DRX inactive period, the network device is in a dormant state. During the DRX ON duration, the UE monitors the PDCCH and receives the PDCCH. The DCI carried by the PDCCH is used to schedule new transmissions. The UE starts or restarts the DRX inactive timer. The value of the DRX inactive timer is a fixed value configured by the network device.

[0151] Figure 6 Indication of UE C-DRX corresponding to the case of adjusting the value of the DRX inactivity timer Figure 1 , for ease of comparison, Figure 6Cell DTX / DRX is also illustrated. During the Cell DTX / DRX activation period, the network device is in an activated state, and during the Cell DTX / DRX inactive period, the network device is in a dormant state. During the DRX ON duration, the UE monitors the PDCCH and receives the PDCCH. The DCI carried by the PDCCH is used to schedule new transmissions, and the DCI is used to indicate that the value of the DRX inactive timer is adjusted to a value of 1, which can be a smaller value. The UE starts or restarts the DRX inactive timer, and the value of the DRX inactive timer is the value 1 indicated by the DCI. Since the value 1 is a smaller value, the running time of the DRX inactive timer is shortened, and the DRX activation period of the UE is shortened, which effectively saves the energy consumption of the UE.

[0152] Figure 7 Indication of UE C-DRX corresponding to the case of adjusting the value of the DRX inactivity timer Figure 2 , for ease of comparison, Figure 7 Cell DTX / DRX is also illustrated. During the Cell DTX / DRX activation period, the network device is in an activated state, and during the Cell DTX / DRX inactive period, the network device is in a dormant state. During the DRX ON duration, the UE monitors the PDCCH and receives the PDCCH. The DCI carried by the PDCCH is used to schedule new transmissions, and the DCI is used to indicate the closure of the DRX inactive timer. The UE closes the DRX inactive timer according to the instruction of the DCI, and the DRX activation period of the UE will be greatly shortened, effectively saving the energy consumption of the UE.
