Description

Technical Field

[0001] Embodiments of the present application relate to the field of wireless communications, and more specifically, to a discontinuous reception method, terminal equipment, and network equipment. Background Art

[0002] For the purpose of power saving of terminal devices, the discontinuous reception (DRX) mechanism is introduced. Each DRX cycle includes an on duration and an opportunity for DRX. During the on duration, the terminal device detects the control channel, while during the opportunity for DRX, the terminal device can stop receiving the control channel (the terminal device stops blind detection of the control channel) to reduce power consumption and thus increase battery life.

[0003] Although the network configures the DRX mechanism for the terminal device, so that the terminal device periodically detects the control channel during the active period, the terminal device is only opportunistically scheduled during the active period. Even when the service load is very low, the terminal device will only be scheduled in a few DRX cycles. For paging messages using the DRX mechanism, the terminal has fewer opportunities to receive paging messages. Therefore, after the DRX mechanism is configured, the terminal device may not be able to detect the control channel in most of the active periods but will still be awakened, which increases unnecessary power consumption. Summary of the invention

[0004] The embodiments of the present application provide a discontinuous reception method, terminal device and network device, which can reduce the power consumption of the terminal device.

[0005] In a first aspect, a method for discontinuous reception is provided, comprising: a first terminal device determines a target DRX cycle for the first terminal device to detect a DRX indication signal for discontinuous reception; the first terminal device detects a DRX indication signal sent by a network device in the target DRX cycle or before the target DRX cycle, the DRX indication signal being used to instruct the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after a moment of detecting the DRX indication signal, the M DRX cycles being the DRX indication cycle of the first terminal device, and M being a positive integer; the first terminal device wakes up or sleeps during an activation period in the M DRX cycles after a moment of detecting the DRX indication signal according to the DRX indication signal.

[0006] Therefore, the terminal device detects its own DRX indication signal at a specific time, and learns whether it is scheduled during the activation period in the subsequent DRX indication cycle based on the detected DRX indication signal, so that it remains dormant when not scheduled to further reduce power consumption. In addition, since the DRX indication signal indicates the wake-up and sleep of multiple terminal devices, different terminal devices detect the DRX indication signal at different time positions, so different terminal devices can reduce interference with each other when detecting the DRX indication signal, further reducing power consumption.

[0007] In one possible implementation, the first terminal device determines a target DRX cycle for the first terminal device to detect a DRX indication signal, including: the first terminal device determines the target DRX cycle in a DRX indication signal cycle used for DRX indication signal detection, the DRX indication signal cycle includes N DRX cycles, N is a positive integer, N=M or N≠M.

[0008] In one possible implementation, the first terminal device determines a target DRX cycle for the first terminal device to detect the DRX indication signal in a DRX indication signal cycle used for performing DRX indication signal detection, including: the first terminal device determines an offset value corresponding to the first terminal device, and the offset value is used to indicate the position of the target DRX cycle in the DRX indication signal cycle; the first terminal device determines the target DRX cycle in the DRX indication signal cycle according to the offset value.

[0009] In a possible implementation, the first terminal device determines the offset value corresponding to the first terminal device, including: the first terminal device determines the offset value according to the device identifier UE-ID of the first terminal device.

[0015] In a possible implementation manner, the DRX indication signal is used to instruct multiple terminal devices including the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after the moment when the DRX indication signal is detected.

[0016] The multiple terminal devices correspond to N DRX cycles in the DRX indication signal cycle, and each DRX cycle in the N DRX cycles is used for the corresponding terminal device to detect the DRX indication signal.

[0017] In one possible implementation, the multiple terminal devices belong to one device group among multiple device groups, and the device group to which the first terminal device belongs is determined based on the UE-ID of the first terminal device, the access level of the first terminal device, or a configuration parameter used to represent the device group.

[0018] In a possible implementation, the system frame number SFN of the system frame starting the DRX indication signal cycle satisfies mod(SFN, N×T)=K, where K is a preconfigured natural number and T is the number of system frames included in the DRX cycle.

[0019] In a second aspect, a method for discontinuous reception is provided, including: a network device determines a target DRX cycle for sending a discontinuous reception DRX indication signal to a first terminal device, the DRX indication signal being used to instruct the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after a moment of detecting the DRX indication signal, the M DRX cycles being the DRX indication cycle of the first terminal device, and M being a positive integer; the network device sends the DRX indication signal to the first terminal device in the target DRX cycle or before the target DRX cycle, so that the first terminal device wakes up or sleeps during an activation period in the M DRX cycles after a moment of detecting the DRX indication signal according to the DRX indication signal.

[0020] Therefore, the network device notifies the terminal device that needs to be awakened or put to sleep by sending a DRX indication signal at a specific time, so that the terminal device can detect the DRX indication signal at the specific time position, and learn whether it is scheduled during the activation period in the subsequent DRX indication cycle according to the detected DRX indication signal, so that it remains in sleep when not scheduled to further reduce power consumption. In addition, since the DRX indication signal indicates the awakening and sleep of multiple terminal devices, different terminal devices detect the DRX indication signal at different time positions, so different terminal devices can reduce interference with each other when detecting the DRX indication signal, further reducing power consumption.

[0021] In one possible implementation, the network device determines a target DRX cycle for sending a DRX indication signal to a first terminal device, including: the network device determines the target DRX cycle in a DRX indication signal cycle used for the terminal device to detect a DRX indication signal, and the DRX indication signal cycle includes N DRX cycles, where N is a positive integer, N=M or N≠M.

[0027] In a possible implementation manner, the method further includes: the network device sending first configuration information to the first terminal device, where the first configuration information is used to indicate the offset value.

[0028] In a possible implementation, before the network device sends the DRX indication signal to the first terminal device in the target DRX cycle or before the target DRX cycle, the method also includes: the network device sends second configuration information to the first terminal device through radio resource control RRC dedicated signaling, broadcast signaling or media access control element MAC CE, and the second configuration information is used to indicate the number N of DRX cycles included in the DRX indication signal cycle.

[0029] In a possible implementation manner, the DRX indication signal is used to instruct multiple terminal devices including the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after the moment when the DRX indication signal is detected.

[0054] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0055] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), and future 5G communication systems, etc.

[0056] The present application describes various embodiments in conjunction with terminal devices. Terminal devices may also refer to user equipment (UE), access terminals, user units, user stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, terminals, wireless communication devices, user agents, or user devices. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, 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 evolving land public mobile communication network (PLMN) network, etc.

[0057] The present application describes various embodiments in conjunction with a network device. The network device may be a device for communicating with a terminal device, for example, a base station (Base Transceiver Station, BTS) in a GSM system or CDMA, a base station (NodeB, NB) in a WCDMA system, or an evolved base station (EvolutionalNode B, eNB or eNodeB) in an LTE system, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, a network side device in a future 5G network, or a network side device in a future evolved PLMN network, etc.

[0058] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present application. Figure 1 The communication system in the embodiment may include a network device 10 and a terminal device 20. The network device 10 is used to provide communication services for the terminal device 20 and access the core network. The terminal device 20 can access the network by searching for synchronization signals, broadcast signals, etc. sent by the network device 10, thereby communicating with the network. Figure 1 The arrows shown in may represent uplink / downlink transmissions performed via a cellular link between the terminal device 20 and the network device 10 .

[0059] The network in the embodiment of the present application may refer to a public land mobile network (PLMN) or a device to device (D2D) network or a machine to machine / man (M2M) network or other networks. Figure 1 This is just a simplified diagram for example. The network may also include other terminal devices. Figure 1 Not drawn in.

[0060] The DRX cycle of the terminal device includes an activation period (on duration) and a dormant period (Opportunity for DRX), for example Figure 2 As shown, the terminal device can detect (or listen to) the Physical Downlink Control Channel (PDCCH) during the activation period, i.e., the on duration period, and the terminal device can reduce power consumption by stopping receiving PDCCH (at this time, the terminal device will stop blind detection of PDCCH or paging messages) during the sleep period, i.e., the Opportunity for DRX, thereby increasing the battery life. It can be said that during the wake-up period, the terminal device is in an awake state to detect PDCCH, and during the sleep period, the terminal device enters a sleep state and does not detect channels or signals.

[0061] Although the network configures the DRX cycle for the terminal device, so that the terminal device periodically detects PDCCH during the active period, the terminal device is only opportunistically scheduled during the active period. Even when the service load is very low, the terminal device will only be scheduled in a few DRX cycles. For paging messages using the DRX mechanism, the terminal has fewer opportunities to receive paging messages. Therefore, after configuring the DRX mechanism, the terminal device may not detect the control channel during the active period of most DRX cycles, but will still be awakened during these DRX active periods, which increases the unnecessary power consumption of the terminal device.

[0062] Therefore, in the embodiment of the present application, the terminal device detects its own DRX indication signal at a specific time, and learns whether it is actually scheduled during the activation period of multiple subsequent DRX cycles according to the DRX indication signal, so as to remain dormant when not scheduled to further reduce power consumption. In addition, when the DRX indication signal indicates the wake-up and sleep of multiple terminal devices, different terminal devices detect the DRX indication signal at different time positions, so different terminal devices can reduce interference with each other when detecting the DRX indication signal, further reducing power consumption.

[0063] The embodiments of the present application can be used not only in the detection of PDCCH, but also in the detection of paging messages. The transmission of paging messages is also a DRX mechanism in the RRC idle state. At this time, the DRX cycle is the paging cycle. The paging radio frame (Paging Frame, PF) is a specific radio frame or system frame. The terminal device can try to receive the paging message at a specific subframe in the PF, namely the paging occasion (Paging Occasion, PO). The PO may transmit a physical downlink control channel (Physical Downlink Control Channel, PDCCH) that is scrambled and indicates the paging message using a paging radio network temporary identity (Paging Radio Network Temporary Identity, P-RNTI). When DRX is used, the terminal device only needs to detect 1 PO in each DRX cycle. That is to say, for each terminal device, only 1 subframe can be used to send a paging message in each DRX cycle. PF is the system frame used to send the paging message, and PO is the subframe in the PF used to send the paging message.

[0064] Figure 3 It is a schematic flowchart of the discontinuous reception method of an embodiment of the present application. Figure 3 The method shown can be executed by a first terminal device, the first terminal device being Figure 1The terminal device 20 shown in FIG. Figure 3 As shown, the discontinuous reception method includes:

[0065] In 310, the first terminal device determines a target DRX cycle for the first terminal device to detect a DRX indication signal.

[0066] In 320, the first terminal device detects a DRX indication signal sent by the network device during or before the target DRX cycle.

[0067] The DRX indication signal is used to instruct the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after the moment when the DRX indication signal is detected, and the M DRX cycles are the DRX indication cycles of the first terminal device, and M is a positive integer.

[0068] In 330, the first terminal device wakes up or sleeps according to the DRX indication signal during the activation period of the M DRX cycles after the moment when the DRX indication signal is detected.

[0069] Specifically, after the first terminal device determines the target DRX cycle for the first terminal device to detect the discontinuous reception DRX indication signal, it can detect the DRX indication signal sent by the network device in the target DRX cycle (for example, detecting the DRX indication signal in the first subframe or the first time slot within the activation period in the DRX cycle), or detecting the DRX indication signal before the target DRX cycle. The DRX indication signal is used to instruct the first terminal device to wake up or sleep during the activation period in the DRX indication cycle of the first terminal device. The DRX indication cycle of the first terminal device includes M DRX cycles, and the activation period in the DRX indication cycle of the first terminal device is the activation period among these M DRX cycles.

[0070] That is to say, the DRX indication period of the first terminal device is the effective duration of the DRX indication signal detected by the first terminal device in the target DRX period or before the target DRX period, and the DRX indication signal can indicate the wakeup and sleep of the terminal device in its DRX indication period (i.e., the subsequent M DRX periods). The DRX indication periods of different terminal devices may be the same or different. The specific value of M can be configured for the terminal device by the network device, or it can be a value pre-stored in the terminal device agreed upon by the network device and the terminal device.

[0071] Optionally, in 310, the first terminal device determines a target DRX cycle for the first terminal device to detect a DRX indication signal, including: the first terminal device determines the target DRX cycle in a DRX indication signal cycle used for DRX indication signal detection, the DRX indication signal cycle includes N DRX cycles, N is a positive integer, N=M or N≠M.

[0072] Specifically, a DRX indication signal cycle is configured, and the DRX indication signal cycle is used for a group of terminal devices to detect the DRX indication signal. One DRX indication signal cycle includes N DRX cycles. The first terminal device in the group of terminal devices determines in which DRX cycle of the DRX indication signal cycle it should detect the DRX indication signal. After the first terminal device determines the target DRX cycle for detecting the DRX indication signal in the DRX indication signal cycle, the first terminal device detects the DRX indication signal in the target DRX cycle or before the target DRX cycle, and wakes up or sleeps according to the indication of the DRX indication signal within the activation period of M DRX cycles after the moment of detecting the DRX indication signal.

[0073] It should be understood that in the embodiments of the present application, the DRX cycle, the DRX indication cycle and the DRX indication signal cycle have different meanings. Figure 2 The time period shown in ; the DRX indication period includes M DRX periods, indicating that after the terminal device detects the DRX indication signal, it can execute the indication of the DRX indication signal in the next DRX indication period, that is, wake up or sleep; the DRX indication signal period includes N DRX periods, and the DRX indication signal period is used for a group of terminal devices to detect the DRX indication signal. Different DRX periods in these N DRX periods can be used for different terminal devices to detect the DRX indication signal. M can be equal to N or not equal.

[0074] Optionally, the system frame number (SFN) of the system frame (frame for short) at the start of the DRX indication signal cycle satisfies: mod(SFN, N×T)=K, where K is a preconfigured natural number (ie, K is 0 or a positive integer), and T is the number of system frames included in the DRX cycle.

[0075] For example, preferably, when K=0, the DRX indication signal cycle is a time period whose starting frame satisfies mod(SFN, N×T1)=0 and whose length is equal to N×T. If N=4, then SFN=0, then SFN=4×T, then SFN=8×T......., SFN=N×T can be used as the starting frame of the DRX indication signal cycle.

[0076] For another example, when K=1, the DRX indication signal cycle is a time period in which the starting frame satisfies mod(SFN, N×T1)=1 and the length is equal to N×T. If N=4, then SFN=1, SFN=4×T+1, then SFN=8×T+1...., SFN=N×T+1 can be used as the starting frame of the DRX indication signal cycle.

[0077] Alternatively, if Figure 4 As shown, 310 includes 311 and 312 .

[0078] In 311, the first terminal device determines an offset value corresponding to the first terminal device, where the offset value is used to indicate the position of the target DRX cycle in the DRX indication signal cycle.

[0079] In 312, the first terminal device determines the target DRX cycle in the DRX indication signal cycle according to the offset value.

[0080] For example, assuming that N=4, that is, the DRX indication signal cycle includes 4 DRX cycles. When the offset value is 0, it indicates that the target DRX cycle used by the first terminal device to detect the DRX indication signal is the first DRX cycle of the N DRX cycles; when the offset value is 1, it indicates that the target DRX cycle is the second DRX cycle of the N DRX cycles; when the offset value is 2, it indicates that the target DRX cycle is the third DRX cycle of the N DRX cycles; when the offset value is 3, it indicates that the target DRX cycle is the fourth DRX cycle of the N DRX cycles.

[0081] The embodiments of the present application propose three methods for the first terminal device to determine its corresponding offset value, which are described in detail below.

[0082] Method 1

[0083] Optionally, in 311, the first terminal device determines the offset value corresponding to the first terminal device, including: the first terminal device determines the offset value according to the equipment identity (UE-ID) of the first terminal device.

[0084] For example, the offset value corresponding to the first terminal device is mod(UE-ID, N), or written as (UE-ID) mod N. N is the number of DRX cycles included in a DRX indication cycle, and mod is the remainder.

[0085] Method 2

[0086] Optionally, in 311, the first terminal device determines an offset value corresponding to the first terminal device, including: the first terminal device determines the offset value according to a cell (Cell) identifier (Cell ID) of a resident cell or a serving cell of the first terminal device.

[0087] For example, the offset value corresponding to the first terminal device is mod(Cell ID, N), or written as (Cell ID) mod N. N is the number of DRX cycles included in a DRX indication cycle, and mod is the remainder.

[0088] Method 3

[0089] Optionally, in 311, the first terminal device determines the offset value corresponding to the first terminal device, including: the first terminal device receives first configuration information sent by a network device, and the first configuration information is used to indicate the offset value.

[0090] After the first terminal device determines the corresponding offset value based on one of the above three methods, it determines the target DRX cycle for the first terminal device to detect the DRX indication signal in the DRX indication cycle according to the offset value.

[0091] For example, if Figure 5 As shown, assuming that N=4, that is, one DRX indication signal cycle includes 4 DRX cycles, if the first terminal device determines that the offset value corresponding to the first terminal device is 0, then the first terminal device will Figure 5 The DRX indication signal is detected before the first DRX cycle in the DRX indication signal cycle shown in , and the first DRX cycle in the DRX indication signal cycle is the target DRX cycle of the first terminal device. If the DRX indication signal indicates that the first terminal device is to sleep during the activation period of M DRX cycles in the DRX indication cycle after the moment of detecting the DRX indication signal, then the terminal device can be in sleep mode during the activation period of these M DRX cycles. When M=4, the DRX indication cycle of the first terminal device is the same as the DRX indication signal cycle.

[0092] Similarly, if the first terminal device determines that the offset value corresponding to the first terminal device is 1, then the first terminal device can detect the DRX indication signal before the second DRX cycle in the DRX indication signal cycle. If the DRX indication signal indicates wake-up, the first terminal device is in an awake state during the activation period of M DRX cycles in the DRX indication cycle after the moment of detecting the DRX indication signal.

[0093] From the Figure 5It can be seen from the description that the DRX indication signal detected by the terminal device can indicate the wake-up and sleep of the terminal device in M ​​DRX cycles at one time. These M DRX cycles are the DRX indication cycles corresponding to the first terminal device. The positions of the DRX indication cycles of terminal devices using different target DRX cycles may also be different.

[0094] Optionally, before 310, that is, before the first terminal device determines, in the DRX indication signal cycle, a target DRX cycle for the first terminal device to detect a DRX indication signal, the method further includes: the first terminal device receives second configuration information sent by the network device through a radio resource control (RRC) dedicated signaling, a broadcast signaling, or a media access control (MAC) control element (CE), the second configuration information being used to indicate the length of the DRX indication signal cycle, that is, the number N of DRX cycles included in the DRX indication signal cycle.

[0095] For example, the DRX indication signal related to the paging message can be used by the network device to inform the first terminal device of relevant configuration information such as the above-mentioned first configuration information and / or second configuration information through RRC signaling during the power-on attachment process.

[0096] For another example, for a first terminal device in a connected state, the network device may inform the first terminal device of relevant configuration information such as the first configuration information and / or the second configuration information through RRC dedicated signaling or MAC CE.

[0097] Optionally, in 320, the DRX indication signal is used to instruct multiple terminal devices including the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after the moment when the DRX indication signal is detected.

[0098] The multiple terminal devices correspond to N DRX cycles in the DRX indication signal cycle, and each DRX cycle in the N DRX cycles is used for the corresponding terminal device to detect the DRX indication signal.

[0099] Optionally, the multiple terminal devices belong to one device group among multiple device groups, and the device group to which the first terminal device belongs is determined based on the UE-ID of the first terminal device, the access level of the first terminal device, or a configuration parameter used to represent the device group.

[0100] Specifically, the network device can simultaneously indicate the wake-up and sleep of multiple terminal devices, and the multiple terminal devices belong to one device group among multiple device groups. The multiple terminal devices in the device group can be further divided into N subsets, and the N subsets correspond to N DRX cycles in the DRX indication signal cycle. The terminal devices in each subset detect the DRX indication signal in the corresponding DRX cycle, and determine whether to sleep or wake up according to the indication of the DRX indication signal in N DRX cycles after the moment of detecting the DRX.

[0101] That is to say, the network device will send DRX indication signals in N DRX cycles in the DRX indication signal cycle, but the DRX indication signal sent in each DRX cycle in the N DRX cycles is for the terminal devices in the subset corresponding to each DRX cycle. If the DRX indication signal sent by the network device in a certain DRX cycle indicates wake-up, then the terminal device that detects the DRX indication signal in the DRX cycle will wake up in the active period of the DRX indication cycle after the moment of detecting the DRX indication signal, and the DRX indication cycle includes M DRX cycles; if the DRX indication signal sent by the network device in a certain DRX cycle indicates sleep, then the terminal device that detects the DRX indication signal in the DRX cycle will sleep in the active period of the DRX indication cycle after the moment of detecting the DRX indication signal.

[0102] The reason for setting the DRX indication signal cycle and setting the time for different terminal devices to detect the DRX indication signal to different DRX cycles in the DRX indication signal cycle is that when the network device simultaneously instructs a group of terminal devices to wake up or sleep, if only a few terminal devices or even only one terminal device among the multiple terminal devices in the group needs to be awakened, then the network device will also send the DRX indication signal to the multiple terminal devices at the same time. In this way, other terminal devices that have no data transmission also need to be awakened, which affects the power consumption of other terminal devices.

[0103] However, in an embodiment of the present application, although the DRX indication signal sent by the network device in the target DRX cycle can indicate the wakeup or sleep of the terminal devices belonging to the same device group, different terminal devices in the device group may detect the DRX indication signal in different DRX cycles in the DRX indication signal cycle. Since different terminal devices in the device group detect the DRX indication signal at different time positions, the terminal devices that do not detect the DRX indication signal avoid unnecessary wakeup, thereby reducing power consumption.

[0104] Even if they are grouped into the same device group, the terminal devices in the device group may detect the DRX indication signal at different times (eg, different DRX cycles corresponding to different offset values), thereby reducing mutual influence among the terminal devices in the same device group when detecting the DRX indication signal.

[0105] For example, the device group to which the first terminal device belongs includes 8 terminal devices, and one DRX indication signal cycle includes four DRX cycles. Then each of the four DRX cycles can correspond to 2 terminal devices, that is, each DRX cycle is only used for the corresponding 2 terminal devices to detect the DRX indication signal. In which DRX cycle does each of the 8 terminal devices detect the DRX indication signal? For example, the corresponding offset value can be determined by the three aforementioned methods, and the DRX cycle in which the terminal device detects the DRX indication signal can be determined according to the offset value. For example, as shown in Table 1, assuming that the DRX cycle corresponding to each terminal device is determined according to the UE-ID, terminal device 1 and terminal device 4 detect the DRX indication signal in the first DRX cycle, terminal device 2 and terminal device 5 detect the DRX indication signal in the second DRX cycle, terminal device 3 and terminal device 6 detect the DRX indication signal in the third DRX cycle, and terminal device 4 and terminal device 8 detect the DRX indication signal in the fourth DRX cycle.

[0106] Table 1

[0107] 4 DRX cycles in the DRX indication cycle 8 terminal devices in the device group The first DRX cycle Terminal device 1 and terminal device 4 Second DRX cycle Terminal device 2 and terminal device 5 The third DRX cycle Terminal device 3 and terminal device 6 The fourth DRX cycle Terminal device 4 and terminal device 8

[0108] Assuming that the first terminal device is the terminal device 2 here, the terminal device 2 can be in the awake state during the activation period of its DRX indication cycle, and its DRX indication cycle can, for example, include M DRX cycles starting from the second DRX cycle or include M DRX cycles starting from the next DRX cycle, i.e., the third DRX cycle. At this time, since only the terminal device 5 and the terminal device 2 detect the DRX indication signal in the second DRX cycle, only the terminal device 5 and the terminal device 2 will be awakened, and other terminal devices that do not need to be awakened will not be awakened. Compared with 8 terminal devices detecting the DRX indication signal at the same time and thus being awakened at the same time, different terminal devices can greatly reduce the power consumption of those terminal devices that do not detect the DRX indication signal in the second DRX cycle by detecting the DRX indication signal in different DRX cycles.

[0109] Therefore, in the embodiment of the present application, the terminal device detects its own DRX indication signal at a specific time, and learns whether it is scheduled during the activation period in the subsequent DRX indication cycle according to the detected DRX indication signal, so as to remain dormant when not scheduled to further reduce power consumption. In addition, since the DRX indication signal indicates the wake-up and sleep of multiple terminal devices, different terminal devices detect the DRX indication signal at different time positions, so different terminal devices can reduce interference with each other when detecting the DRX indication signal, further reducing power consumption.

[0110] Figure 6 It is a schematic flowchart of the discontinuous reception method of an embodiment of the present application. Figure 6 The method shown may be performed by a network device, which may be, for example, Figure 1 The network device 10 shown in FIG. Figure 6 As shown, the discontinuous reception method includes:

[0111] In 610, the network device determines a target DRX cycle for sending a discontinuous reception DRX indication signal to the first terminal device.

[0112] The DRX indication signal is used to instruct the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after the moment when the DRX indication signal is detected, and the M DRX cycles are the DRX indication cycles of the first terminal device, and M is a positive integer.

[0113] In 620, the network device sends the DRX indication signal to the first terminal device in the target DRX cycle or before the target DRX cycle, so that the first terminal device wakes up or sleeps during the activation period of the M DRX cycles after the moment of detecting the DRX indication signal according to the DRX indication signal.

[0114] Optionally, the network device determines a target DRX cycle for sending a DRX indication signal to the first terminal device, including: the network device determines the target DRX cycle in a DRX indication signal cycle used for the terminal device to perform DRX indication signal detection, and the DRX indication signal cycle includes N DRX cycles, N is a positive integer, N=M or N≠M.

[0115] Specifically, a DRX indication signal cycle is configured, and the DRX indication signal cycle is used to send a DRX indication signal to a group of terminal devices, and one DRX indication signal cycle includes N DRX cycles. The network device sends corresponding DRX indication signals in these N DRX cycles, wherein the terminal device receiving the DRX indication signal can wake up or sleep according to the DRX indication signal during the activation period of M DRX cycles (i.e., the DRX indication cycle of the first terminal device) after the moment of detecting the DRX indication signal. Different terminal devices in this group of terminal devices can detect the DRX indication signal in different DRX cycles in the DRX indication signal cycle. For example, the network device needs to notify the first terminal device in the group of mid-terminal devices to wake up, so the network device determines a target DRX cycle for the first terminal device to detect the DRX indication signal in the DRX indication signal cycle, and sends a DRX indication signal for indicating wake-up in the target DRX cycle. The first terminal device detects the DRX indication signal in the target DRX cycle, and wakes up according to the indication of the DRX indication signal within the activation period of M DRX cycles (i.e., the DRX indication cycle of the first terminal device) after the moment of detecting the DRX indication signal.

[0116] Therefore, in the embodiment of the present application, the network device notifies the terminal device that needs to be awakened or dormant by sending a DRX indication signal at a specific time, so that the terminal device can detect the DRX indication signal at the specific time position, and learn whether it is scheduled during the activation period in the subsequent DRX indication cycle according to the detected DRX indication signal, so that it remains asleep when not scheduled to further reduce power consumption. In addition, since the DRX indication signal indicates the awakening and dormancy of multiple terminal devices, different terminal devices detect the DRX indication signal at different time positions, so different terminal devices can reduce interference with each other when detecting the DRX indication signal, further reducing power consumption.

[0117] Optionally, the network device determines a target DRX indication cycle for sending a DRX indication signal in a DRX indication signal cycle for sending a discontinuous reception DRX indication signal, including: the network device determines an offset value corresponding to the first terminal device, and the offset value is used to indicate the position of the target DRX cycle in the DRX indication signal cycle; the network device determines the target DRX cycle in the DRX indication signal cycle according to the offset value.

[0123] Optionally, before the network device sends the DRX indication signal to the first terminal device in the target DRX cycle, the method also includes: the network device sends second configuration information to the first terminal device through radio resource control RRC dedicated signaling, broadcast signaling or media access control element MAC CE, and the second configuration information is used to indicate the number N of DRX cycles included in the DRX indication signal cycle.

[0124] Optionally, the DRX indication signal is used to instruct multiple terminal devices including the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after the moment when the DRX indication signal is detected.

[0125] The multiple terminal devices correspond to N DRX cycles in the DRX indication signal cycle, and each DRX cycle in the N DRX cycles is used for the corresponding terminal device to detect the DRX indication signal.

[0126] Optionally, the multiple terminal devices belong to one device group among multiple device groups, and the device group to which the first terminal device belongs is determined based on the UE-ID of the first terminal device, the access level of the first terminal device, or a configuration parameter used to represent the device group.

[0127] Optionally, the DRX indication signal period satisfies T2=mod(SFN, M×T1), wherein SFN is the system frame number of the system frame where the DRX indication signal period is located, T2 is the length of the DRX indication signal period, and T1 is the length of the DRX period.

[0128] It should be understood that the specific details of the process in which the network device determines the target DRX cycle and sends the DRX indication signal can refer to the aforementioned Figures 3 to 5 For the sake of brevity, the relevant description of the terminal device is not repeated here.

[0129] It should also be understood that in the various embodiments of the present application, the size of the serial numbers of the above-mentioned processes does not mean the order of execution.

[0143] Optionally, the DRX indication signal is used to instruct multiple terminal devices including the first terminal device to wake up or sleep during an activation period in M ​​DRX cycles after the moment when the DRX indication signal is detected.

[0144] The multiple terminal devices correspond to N DRX cycles in the DRX indication signal cycle, and each DRX cycle in the N DRX cycles is used for the corresponding terminal device to detect the DRX indication signal.

[0145] Optionally, the multiple terminal devices belong to one device group among multiple device groups, and the device group to which the first terminal device belongs is determined based on the UE-ID of the first terminal device, the access level of the first terminal device, or a configuration parameter used to represent the device group.
