Abstract

The embodiment of the present application provides a DRX control method and apparatus, which can flexibly control the activation time of different DRXs when a terminal device is configured with multiple DRXs. For example, a network device can send indication information to a terminal device on a first service cell of the terminal device, instructing the terminal device to start, extend or end the DRX activation time of a second service cell of the terminal device, wherein the first service cell is configured with a first DRX and the second service cell is configured with a second DRX. The network device sends indication information based on the first DRX, and when data arrives, the second DRX of the terminal device can return to the DRX activation time to monitor the PDCCH, so as to reduce data latency and improve system throughput, and when there is no data, the second DRX of the terminal device can be maintained or returned to the DRX inactive time to save power consumption.

Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a discontinuous reception (DRX) control method and device. Background Art

[0002] In the new radio (NR) system specified by the 3rd Generation Partnership Project (3GPP) protocol, the frequency range of wireless transmission can be divided into FR1 band and FR2 band, where the frequency range of FR1 band is 410MHz-7125MHz, and the frequency range of FR2 band is 24.25GHz-52.6GHz. In the carrier aggregation (CA) scenario, a terminal device can be configured with multiple carriers, and each configured carrier is called a subcarrier (component carrier, CC). The terminal device can be configured with subcarriers in FR1, or configured with subcarriers in FR2, or configured with subcarriers in FR1 and subcarriers in FR2 at the same time.

[0003] In actual situations, each service cell of a terminal device may not have data transmission requirements. If the terminal device maintains DRX activation time on all service cells at the same time, unnecessary power consumption will be consumed. In order to reduce power loss when configuring DRX in CA scenarios, 3GPP proposes that the same terminal device can be configured with 2 DRXs (such as the first DRX and the second DRX), and each DRX corresponds to a set of DRX parameters.

[0004] However, when one DRX (such as the first DRX) is in the DRX activation time and another DRX (such as the second DRX) is in the DRX deactivation time, if more data arrives, the network can only transmit data on the service cell corresponding to the first DRX, but cannot transmit data on the service cell corresponding to the second DRX, which is not conducive to improving the system throughput and will increase data latency. Summary of the invention

[0005] An embodiment of the present application provides a DRX control method and apparatus for flexibly controlling the activation time of different DRXs (or different subcarriers) when a terminal device is configured with multiple DRXs, so as to reduce data transmission delay and improve system throughput. In addition, it can also reduce the power consumption of the terminal device.

[0006] An embodiment of the present application provides a DRX control method and apparatus for flexibly controlling the activation time of different DRXs (or different subcarriers) when a terminal device is configured with multiple DRXs, so as to reduce data transmission delay and improve system throughput.

[0007] In a first aspect, a DRX control method is provided, comprising: a terminal device receives indication information sent by a network device on a first service cell of the terminal device, wherein the indication information is used to instruct the terminal device to start, extend or end the DRX activation time of a second service cell of the terminal device, the first service cell is configured with a first DRX, the second service cell is configured with a second DRX, and the activation time of the service cell configured with the first DRX is different from the activation time of the service cell configured with the second DRX; the terminal device starts, extends or ends the DRX activation time of the second service cell according to the indication information.

[0008] In the embodiment of the present application, the network device can indicate the DRX state of another DRX based on one DRX (i.e., cross-DRX group or cross-carrier indication), and can more flexibly control the DRX state of the terminal device in different DRXs. When data arrives, other DRXs can be returned to the DRX activation time to monitor the PDCCH, thereby improving the throughput of the terminal device and reducing data latency; when there is no data, other DRXs can be maintained or returned to the DRX inactive time, so that the terminal device can shut down the RF link corresponding to other DRXs, thereby saving power consumption.

[0009] In one possible design, the terminal device can receive first indication information on the first service cell during the DRX inactivation time of the second service cell, and the first indication information is used to instruct the terminal device to start the DRX inactivation timer corresponding to the second DRX; the terminal device can start the DRX inactivation timer corresponding to the second DRX during the DRX inactivation time of the second service cell according to the first indication information, so as to end the DRX inactivation time of the second service cell and start the DRX activation time of the second service cell.

[0010] In this design, the network device sends a first indication message to the terminal device on the first service cell during the DRX inactivation time of the second service cell, so that the terminal device starts the DRX inactivation timer corresponding to the second DRX, and then ends the DRX inactivation time of the second service cell and starts the DRX activation time of the second service cell, so that the second service cell can transmit data, which can improve the throughput of the terminal device and reduce data latency. In a possible design, the terminal device can also receive a PDCCH for indicating new data transmission on any service cell configured with the second DRX during the DRX activation time of the second service cell, and start or restart the DRX inactivation timer corresponding to the second DRX.

[0011] In this design, when the second DRX is in the activation time, if the terminal device receives a PDCCH for new data transmission on any service cell configured with the second DRX, the DRX inactivation timer corresponding to the second DRX is started or restarted, thereby extending the activation time of the second DRX, which can further improve the terminal device throughput and reduce data latency.

[0012] In one possible design, the terminal device can receive second indication information on the first service cell at the DRX activation time of the second service cell, and the second indication information is used to instruct the terminal device to start or restart the DRX inactivation timer corresponding to the second DRX; the terminal device can start or restart the DRX inactivation timer corresponding to the second DRX at the DRX activation time of the second service cell according to the second indication information to extend the DRX activation time of the second service cell.

[0013] In this design, when the second DRX is in the activation time, if the terminal device receives the second indication information on the first service cell, it starts or restarts the DRX inactivation timer corresponding to the second DRX, thereby extending the activation time of the second DRX, which can further improve the terminal device throughput and reduce data latency.

[0014] In one possible design, the terminal device may receive third indication information on the first service cell at the DRX activation time of the second service cell, and the third indication information is used to instruct the terminal device to stop the DRX inactivation timer corresponding to the second DRX; the terminal device may stop the DRX inactivation timer corresponding to the second DRX at the DRX activation time of the second service cell according to the third indication information, so as to end the DRX activation time of the second service cell and start the DRX inactivation time of the second service cell.

[0015] In this design, when the second DRX is in the activation time, if the terminal device receives the third indication information on the first service cell, the DRX inactivation timer corresponding to the second DRX is stopped, and then the activation time of the second DRX is ended, which can save power consumption.

[0016] In one possible design, the terminal device may also receive indication information sent by the network device on the third service cell of the terminal device, wherein the indication information sent by the network device on the third service cell is used to instruct the terminal device to start, extend or end the DRX activation time of the first service cell of the terminal device, and the third service cell configures the second DRX; the terminal device starts, extends or ends the DRX activation time of the first service cell according to the indication information sent by the network device on the third service cell.

[0017] In this design, the network device can not only control the state switching of other DRXs (such as the second DRX) based on the first DRX, but also control the state switching of the first DRX based on other DRXs (such as the third DRX can be the second DRX, or other DRX different from the second DRX), further improving the flexibility of the DRX control method.

[0074] The terminal device can be configured with a discontinuous reception (C-DRX or DRX) mechanism in the Radio Resource Control (RRC) connected state, so that the terminal device enters the DRX duration (ON Duration) at regular intervals, monitors the Physical Downlink Control Channel (PDCCH) and sends and receives data during the ON Duration, and can enter a sleep state at other times without monitoring the PDCCH, thereby saving power consumption of the terminal device.

[0075] When a terminal device is configured with DRX, the state of the terminal device can be divided into a DRX active state and a DRX non-active state (or sleep state). The time when the terminal device is in the DRX active state is called the active time, and the time when the terminal device is in the DRX non-active state is called the non-active time. When the terminal device is in the DRX active time, the terminal device will continue to monitor the PDCCH. If the terminal device leaves the DRX active state, that is, enters the sleep state, the terminal does not monitor the PDCCH, which can save power consumption.

[0076] When any of the following timers is running, the terminal device is in the DRX activation state (i.e., in the DRX activation time):

[0077] DRX duration timer (drx-onDurationTimer);

[0078] DRX inactivity timer (drx-InactivityTimer);

[0079] DRX downlink retransmission timer (drx-RetransmissionTimerDL);

[0080] DRX uplink retransmission timer (drx-RetransmissionTimerUL);

[0081] Random access contention resolution timer (ra-ContentionResolutionTimer).

[0082] In addition, the DRX activation time also includes other situations, such as: the waiting period after the terminal device sends a scheduling request (SR) on the PUCCH; the period when the terminal device has not received a PDCCH indicating a new transmission after successfully receiving a random access response (Random Access Response, RAR) based on non-contention based random access.

[0083] Figure 1 The figure is a state diagram of a terminal device configured with the C-DRX mechanism. At the beginning of the C-DRX cycle, the terminal will first enter the ON Duration and start the timer drx-onDurationTimer (when the timer starts running, it enters the DRX activation time). If during the operation of drx-onDurationTimer, the terminal device receives a PDCCH indicating new downlink or uplink data transmission, the terminal device will start (or restart) the timer drx-InactivityTimer, so that the terminal device is always in the DRX activation state (it can be understood that the original length of time the terminal device is in the activation state is the length of the ON Duration, and running drx-InactivityTimer can extend the time the terminal device is in the activation state), until the drx-InactivityTimer timer times out, or the terminal device receives a related media access control (MAC) control element (CE) signaling to stop the drx-InactivityTimer timer in advance, the terminal device ends the activation time and enters the inactive time (that is, the terminal device enters the sleep state from the activation state). It is easy to understand that the DRX duration (ON Duration) described here represents a time period, which is determined by the timer drx-onDurationTimer, and the length of the duration is equal to the size of the timer drx-onDurationTimer configured by the network device.

[0084] The drx-InactivityTimer is usually started or restarted in the first symbol after the PDCCH used to indicate new data transmission. Figure 2 As shown, Figure 2 The PDCCH is used to schedule new physical downlink shared channel (PDSCH) transmission.

[0085] As mentioned above, when the terminal device is in the DRX active state, it will continue to monitor the PDCCH. If the terminal device leaves the DRX active state (enters the sleep state), it will not monitor the PDCCH. Therefore, running the drx-InactivityTimer during the ON Duration period can keep the terminal device in the DRX active state for a longer time and continue to monitor the PDCCH until the drx-InactivityTimer stops running.

[0086] In the new radio (NR) system specified by the 3rd Generation Partnership Project (3GPP) protocol, the frequency range of wireless transmission is divided into FR1 band and FR2 band, where the frequency range of FR1 band is 410MHz-7125MHz, and the frequency range of FR2 band is 24.25GHz-52.6GHz. The FR2 band is located in the high frequency band, commonly known as millimeter wave (mmWave). In the carrier aggregation (CA) scenario, a terminal device can be configured with multiple carriers, and each configured carrier is called a subcarrier (Component Carrier, CC). The terminal device can be configured with subcarriers within FR1, or configured with subcarriers within FR2, or configured with subcarriers within FR1 and subcarriers within FR2 at the same time.

[0087] The power consumption of terminal devices in CA scenarios is higher than that in non-CA scenarios, especially when carrier aggregation is performed between FR1 and FR2. The main reasons are as follows: The working bandwidth of CA scenarios is relatively high. When the terminal device works in inter-band CA, it needs to open multiple RF links to connect to multiple subcarriers in the inter-band, which causes the terminal device to perform more data monitoring and decoding per unit time. On the high-frequency subcarriers in FR2, the terminal device also needs to maintain the connection beam with the base station, so the terminal device also needs to perform beam management measurements.

[0088] When DRX is configured, the terminal device has a higher power consumption during the DRX activation time. As described in the background above, the terminal device needs to periodically enter the DRX activation time to monitor the PDCCH. Monitoring the PDCCH, receiving and decoding the PDSCH or sending the PUSCH consumes a higher power. When the data is sparse, the network device does not send the PDCCH scheduling data, so the terminal device will consume unnecessary power consumption when monitoring the PDCCH. In addition, the terminal device also needs to perform some measurements and uplink transmissions during the DRX activation time, such as channel state information (CSI) / layer 1 reference signal received power (L1-RSRP) measurement, radio resource management (RRM) measurement, CSI / L1-RSRP reporting, sounding reference signal (SRS) transmission, etc.

[0089] The power consumption of the terminal device is high when DRX is configured in the CA scenario. The network equipment is generally configured with only one set of DRX parameters, and a media access control entity (MAC entity) of the terminal device only runs one set of DRX parameters. The DRX state of the terminal device applies to all service cells under CA (it should be understood that the "service cell" involved in this article can also be referred to as "cell" for short). If the terminal device is in DRX active time, all activated service cells of the terminal device are in DRX active time, and the terminal device must monitor PDCCH on all activated service cells. However, in actual situations, not every service cell has the need for data transmission, so it will consume unnecessary power if the terminal device maintains DRX active time on all service cells at the same time.

[0090] In order to reduce the power loss when configuring DRX in the CA scenario, 3GPP proposes to configure 2 DRXs (or 2 DRX modes) in the CA scenario. Each DRX corresponds to a set of DRX parameters, and the states of the terminal device in different DRX configurations are independent of each other (it can be understood that the terminal device runs each DRX mode independently). In this article, one or more cells configured with the same DRX can be referred to as a DRX group. For example, one or more cells configured with the first DRX are referred to as the first DRX group, and one or more cells configured with the second DRX are referred to as the second DRX group. If a cell is configured with the first DRX, it can be considered that the cell is configured to the first DRX group. If a cell is configured with the second DRX, it can be considered that the cell is configured to the second DRX group.

[0091] It should be understood that descriptions such as "configuring DRX", "configuring DRX mode", "configuring DRX parameters", and "configuring DRX group" in this article can be interpreted mutually, for example, they can refer to the same meaning.

[0092] Furthermore, the DRX parameters of the first DRX and the second DRX can be different. For example, these two DRXs can be configured with different drx-onDurationTimer and / or different drx-InactivityTimer. For example, the first DRX is configured with drx-onDurationTimer-1 and drx-InactivityTimer-1, and the second DRX is configured with drx-onDurationTimer-2 and drx-InactivityTimer-2. If the network configures the value of one or both of these two timers of one of the DRXs to be smaller than the value of the other DRX respectively, for example, drx-onDurationTimer-2 < drx-onDurationTimer-1, drx-InactivityTimer-2 < drx-InactivityTimer-1, then it is easy to understand that when there is no data transmission or the data transmission on the serving cell corresponding to the second DRX is sparse, the DRX activation time of the second DRX is shorter than that of the first DRX. Therefore, the terminal device can enter the DRX inactive time faster on the subcarriers of the second DRX, thereby reducing the power consumption loss on the subcarriers configured with the second DRX, as Figure 3 shown, Figure 3 in, the subcarriers within FR1 are configured with the first DRX, and the subcarriers within FR2 are configured with the second DRX.

[0093] In addition to the two timers of drx-onDurationTimer and drx-InactivityTimer, the other DRX parameters of the first DRX and the second DRX can be the same or different, and can be configured independently or share DRX parameters, which is not limited in the present invention. For example, the two DRXs can share other DRX parameters, have the same long cycle (Long DRX cycle) parameters, the same short cycle parameters (short DRX cycle), etc.

[0094] As described above, when the terminal device is configured with 2 DRXs (or 2 DRX groups, 2 groups of DRX parameters, etc.), the 2 DRXs can be configured with independent drx-onDurationTimer and / or drx-InactivityTimer. The two DRXs of the terminal device independently control the corresponding drx-onDurationTimer and / or drx-InactivityTimer, so the DRX states of the terminal device in the two DRXs can be different. In this way, compared with a set of DRX configurations, the DRX activation time of the terminal device can be controlled more flexibly to achieve the purpose of saving power consumption.

[0095] However, when the serving cell of one DRX (e.g., the first DRX) is in the DRX activation time and the serving cell of another DRX (the second DRX) is in the DRX inactivation time, if more data arrives, the network can only transmit data on the cell corresponding to the first DRX, but not on the cell corresponding to the second DRX. Figure 4 As shown, the terminal device is configured with carrier aggregation of FR1 cell and FR2 cell, FR1 cell is configured with first DRX (i.e., in the first DRX group), and FR2 cell is configured with second DRX (i.e., in the second DRX group). When FR1 cell is in DRX activation time and FR2 cell is not in DRX activation time, if more data arrives, the second DRX of FR2 cell is in DRX non-activation time, so the data can only be transmitted on FR1 cell in another DRX group. If the network device wants to transmit data in FR2 cell, it can only wait until the next DRX cycle of the second DRX. This is not conducive to improving system throughput and will increase data latency.

[0096] In view of this, an embodiment of the present application provides a DRX control method and device for effectively controlling the activation time of different DRXs when a terminal device is configured with multiple DRXs, thereby saving power consumption without reducing the throughput of the terminal device and increasing the data delay of the terminal device.

[0097] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as the fourth generation (4G) communication system, the fifth generation (5G) communication system, the machine type communication (MTC) system, the device to device (D2D) system, the Internet of Things (IoT) system, the vehicle-to-everything (V2X) system, the narrowband Internet of Things (NB-IoT) system, and new communication systems emerging in the future communication development, as long as the communication entity in the communication system can be configured with multiple sets of DRX parameters, where one DRX corresponds to a set of DRX parameters.

[0098] For example, Figure 5 A network architecture applicable to an embodiment of the present application, wherein the communication system includes a network device and a terminal device. In the communication system, the network device can send a signal to the terminal device via a downlink channel, and the terminal device can send a signal to the network device via an uplink channel.

It also includes limited devices, such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, it includes information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning systems (GPS), laser scanners, etc.

[0100] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for the application of wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-size, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0101] The various terminal devices introduced above, if located on a vehicle (eg, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBU).

[0102] Network equipment, for example, includes access network (AN) equipment and radio access network (RAN) equipment. Access network equipment such as base stations (e.g., access points) may refer to equipment in an access network that communicates with wireless terminal devices over an air interface through one or more cells. The base station may be used to convert received air frames to and from Internet Protocol (IP) packets, acting as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. The network equipment may also coordinate the attribute management of the air interface. For example, the network device may include an evolved base station (NodeB or eNB or e-NodeB, evolved Node B) in a long term evolution (LTE) system or an advanced long term evolution (LTE-A), or may also include a next generation node B (next generation node B, gNB) or a next generation evolved node B (next generation evolved nodeB, ng-eNB), en-gNB (enhanced next generation node B, gNB) in a fifth generation mobile communication technology (the 5th generation, 5G) new radio (new radio, NR) system: an enhanced next generation base station; it may also include a centralized unit (CU) and a distributed unit (DU) in a cloud access network (Cloud radio access network, Cloud RAN) system, or it may also include a relay device, which is not limited in the embodiments of the present application.

[0103] The above introduces the communication system to which the embodiment of the present application is applicable. Next, the DRX control method provided by the embodiment of the present application is introduced in conjunction with the accompanying drawings.

[0104] It should be understood that the terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c.

[0105] Furthermore, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects. For example, the first priority criterion and the second priority criterion are only used to distinguish different criteria, and do not indicate the difference in the content, priority or importance of the two criteria.

[0106] like Figure 6 As shown, the embodiment of the present application provides a DRX control method, which can be applied to Figure 5 The communication system shown.

[0107] The method includes:

[0108] S601. The network device sends indication information on the first service cell of the terminal device, and the terminal device receives the indication information, wherein the first service cell is configured with a first DRX.

[0109] S602. The terminal device starts, extends or ends the DRX activation time of the second service cell according to the indication information, wherein the second service cell is configured with a second DRX.

[0110] Specifically, in an embodiment of the present application, a terminal device may reside in multiple service cells (eg, a primary service cell and one or more secondary service cells) of a network device at the same time, wherein different service cells are on different subcarriers.

[0111] The network device may be configured with at least two DRXs, where the at least two DRXs include the first DRX and the second DRX, and may also include other DRXs.

[0112] Each service cell of the terminal device is configured with a DRX, wherein the DRXs configured in different service cells may be the same or different.

[0113] The service cells configured with the same DRX may be referred to as a DRX group, that is, the cells in the same DRX group are configured with the same DRX (that is, configured with the same DRX parameters).

[0114] Exemplarily, the service cell configured with the first DRX is the first DRX group, which includes the above-mentioned first service cell. Therefore, the configuration of the first DRX in the above-mentioned first service cell can be understood as the first service cell being configured to the first DRX group; the service cell configured with the second DRX is the second DRX group, which includes the above-mentioned second service cell. Similarly, the configuration of the second DRX in the above-mentioned second service cell can be understood as the second service cell being configured to the second DRX group.

[0115] In the embodiment of the present application, the DRX activation time of different DRXs may be different, that is, the activation time of the service cells configured with different DRXs is different. For example, the activation time of the service cell configured with the first DRX (such as the first service cell) and the activation time of the service cell configured with the second DRX (such as the second service cell) may be different.

[0116] Exemplarily, different DRXs may correspond to different timers. For example, the first DRX corresponds to drx-onDurationTimer-1 and drx-InactivityTimer-1, and the second DRX corresponds to drx-onDurationTimer-2 and drx-InactivityTimer-2. The running durations of drx-onDurationTimer-1 and drx-onDurationTimer-2 may be different (i.e., the durations of the first DRX and the second DRX are different). For example, as shown in 7A, the duration of DRX duration timer-1 (drx-onDurationTimer-1) is greater than the duration of DRX duration timer-2 (drx-onDurationTimer-2).

[0117] It should be understood that different activation times of different DRXs are configured here, including different start times and / or end times of the activation times, for example, activation times of different DRXs partially overlap or do not overlap.

[0118] For example, see Fig. 7A or Figure 7B or Figure 7C or Fig.7DThe terminal device is configured with two DRXs, the two DRXs have the same DRX cycle, and the start time of the ON Duration of the two DRXs in each cycle is the same (that is, the start time of drx-onDurationTimer-1 and drx-onDurationTimer-2 is the same), but the end time of the ON Duration is different (that is, the end time of drx-onDurationTimer-1 and drx-onDurationTimer-2 is different).

[0119] Exemplarily, the values ​​of drx-onDurationTimer of different DRXs can also be configured to be the same, so that when there is no data transmission, the activation time of different DRXs is the corresponding duration, and the duration of different DRXs is the same. At this time, it can be considered that there is a partial overlap in the activation time of different DRXs. When there is data transmission, the data size and data arrival time on the service cell corresponding to different DRXs are different, so the start / end time of drx-InactivityTimer of different DRXs is different, so the end time of the activation time of different DRXs will be different.

[0120] It should be understood that the DRX activation time of service cells configured with the same DRX (i.e., located in the same DRX group) is the same. When describing the DRX activation time of a service cell, it means describing the DRX activation time of the DRX configured for the service cell. When the DRX state of a service cell changes (for example, starting / extending / ending the DRX activation time), the DRX state of the DRX configured for the service cell also changes in the same way, and the DRX states of other service cells configured with the same DRX as the service cell also change in the same way.

[0121] One possible design is that the value of the drx-onDurationTimer timer and / or the value of the drx-InactivityTimer timer of the DRX corresponding to the service cell of the low-frequency subcarrier is greater than the value of the corresponding timer of the DRX corresponding to the service cell of the high-frequency subcarrier. For example, the value of the drx-onDurationTimer timer and / or the value of the drx-InactivityTimer timer of the DRX corresponding to the service cell of the subcarrier frequency band FR1 is greater than the value of the corresponding timer of the DRX corresponding to the service cell of the subcarrier frequency band FR2. Because the power consumption of the system is high when working in the high frequency band, by configuring the value of the drx-onDurationTimer timer and / or the drx-InactivityTimer timer of the high frequency band to a smaller value, the corresponding DRX activation time can be shortened, and the power consumption loss of the DRX corresponding to the high frequency band service cell can be reduced. At the same time, the network device can flexibly control the start, extension or end of the activation time of the second DRX through the first DRX to send the indication information, which can take into account the data transmission requirements, reduce data delay, and improve system throughput.

[0122] It should be understood that the present application does not limit the values ​​of drx-onDurationTimer and / or drx-InactivityTimer corresponding to different DRXs, and the values ​​of drx-onDurationTimer and / or drx-InactivityTimer corresponding to different DRXs can be configured to be the same or different. For example, the drx-onDurationTimer and / or drx-InactivityTimer of the DRX corresponding to the service cell with a subcarrier frequency band in FR2 and the corresponding timer corresponding to the service cell with a subcarrier frequency band in FR1 can also be configured to the same value.

[0123] In the embodiment of the present application, the indication information may have at least one of the following functions:

[0124] 1) Instructing the terminal device to start the DRX activation time of the second serving cell of the terminal device;

[0125] 2) instructing the terminal device to extend the DRX activation time of the second serving cell of the terminal device;

[0126] 3) Instruct the terminal device to end the DRX activation time of the second service cell of the terminal device.

[0127] It should be understood that when the network device actually sends the indication information, the indication information sent by the network device indicates one of the functions, for example, it is used to instruct the terminal device to start, extend or end the DRX activation time of the second service cell of the terminal device.

[0128] It should be understood that the indication information sent by the network device has the above functions, which may be pre-defined by the protocol or configured or indicated by the network device.

[0129] The following describes in detail the specific implementations of the above three functions of the indication information.

[0130] Method 1: The indication information instructs the terminal device to start the DRX activation time of the second service cell of the terminal device.

[0131] like Fig. 7A As shown, the network device can send the first indication information on the first service cell during the DRX inactivity time of the second service cell to instruct the terminal device to start the DRX inactivity timer (i.e., drx-InactivityTimer-2) corresponding to the second DRX. Correspondingly, the terminal device receives the first indication information on the first service cell during the DRX inactivity time of the second service cell, and the terminal device starts the DRX inactivity timer corresponding to the second DRX during the DRX inactivity time of the second service cell according to the first indication information to end the DRX inactivity time of the second service cell and start the DRX activation time of the second service cell.

[0132] Combination Fig. 7A The specific implementation process of the above method 1 may include the following steps:

[0133] Step 1: The network device sends first configuration information and second configuration information, and the terminal device receives the first configuration information and the second configuration information.

[0134] The first configuration information includes first DRX configuration information and second DRX configuration information, the first DRX configuration information is used to configure the DRX inactivity timer of the first DRX, and the second DRX configuration information is used to configure the DRX inactivity timer of the second DRX.

[0135] It should be understood that the first DRX configuration information can also be used to configure other DRX parameters of the first DRX except the DRX inactivity timer, and the second DRX configuration information can also be used to configure other DRX parameters of the second DRX except the DRX inactivity timer.

[0136] The second configuration information is used to configure the first cell to the first DRX group and the second cell to the second DRX group. Optionally, the network device may configure the group identifier of the first DRX group for the first cell and the group identifier of the second DRX group for the second cell.

[0137] It should be understood that the first DRX group (or the group identifier of the first DRX group) and the first DRX configuration information are associated, and the second DRX group (or the group identifier of the second DRX group) and the second DRX configuration information are associated. Configuring the first cell to the first DRX group means configuring the first cell with the first DRX, and configuring the second cell to the second DRX group means configuring the second cell with the second DRX.

[0138] Correspondingly, the terminal device configures the DRX inactivity timer of the first DRX and the DRX inactivity timer of the second DRX according to the first configuration information, and configures the first cell to the first DRX group and the second cell to the second DRX group according to the second configuration information.

[0139] Optionally, the terminal device may configure the group identifier of the first DRX group for the first cell to configure the first cell into the first DRX group, and configure the group identifier of the second DRX group for the second cell to configure the second cell into the second DRX group.

[0140] Step 2: When the first DRX group is in the DRX activation time and the second DRX group is in the DRX inactivation time, the network device sends the first indication information on the first cell, and the terminal device receives the first indication information on the first cell.

[0141] The first indication information is used to instruct the terminal device to start the DRX inactivity timer of the second DRX in the second DRX group.

[0142] Step 3: The terminal device starts the DRX inactive timer of the second DRX group, so that the terminal device is in the DRX active time at the beginning of the second DRX group.

[0143] Optionally, if the terminal device receives a physical downlink control channel PDCCH indicating new data transmission on any service cell configured with the second DRX during the DRX activation time of the second service cell, the DRX inactivation timer corresponding to the second DRX can be started or restarted to extend the activation time of the second DRX.

[0144] It should be understood that when the terminal device is in the DRX activation time in the second service cell, the network device does not need to send the first indication information in the first service cell. It only needs to send the physical downlink control channel PDCCH for indicating new data transmission on any service cell configured with the second DRX, so as to extend the DRX activation time of the second DRX of the terminal device.

[0145] In addition, during the DRX activation time of the first service cell, if the terminal device receives a physical downlink control channel PDCCH indicating new data transmission on any service cell configured with the first DRX, the DRX inactivation timer corresponding to the first DRX is started or restarted to extend the activation time of the first DRX.

[0146] Method 2: The indication information is used to instruct the terminal device to extend the DRX activation time of the second service cell of the terminal device.

[0147] Specifically, the network device may send a second indication message on the first service cell at the DRX activation time of the second service cell, and the second indication message is used to instruct the terminal device to start or restart the DRX inactivity timer (i.e., drx-InactivityTimer-2) corresponding to the second DRX. Correspondingly, the terminal device receives the second indication message on the first service cell at the DRX activation time of the second service cell, and starts or restarts the DRX inactivity timer corresponding to the second DRX at the DRX activation time of the second service cell according to the second indication message, so as to extend the DRX activation time of the second service cell.

[0148] More specifically, the first service cell and the second service cell (or the first DRX group and the second DRX group) are both in the DRX activation time. When the terminal device receives the second indication information, if drx-InactivityTimer-2 is not running, the terminal device starts drx-InactivityTimer-2, such as Figure 7B As shown; if drx-InactivityTimer-2 is already running, the terminal device restarts drx-InactivityTimer-2, such as Figure 7C shown.

[0149] In this case, the terminal device in the second DRX group no longer decides whether to start or restart drx-InactivityTimer-2 based on whether a PDCCH indicating a new transmission is received. Even if the UE receives a PDCCH indicating a new transmission on the serving cell of the second DRX group, but does not receive the second indication information instructing the terminal to start / restart drx-InactivityTimer-2, the terminal does not start / restart drx-InactivityTimer-2.

[0150] Combination Figure 7B and Figure 7C The specific implementation process of the above method 2 may include the following steps:

[0151] Step 1: The network device sends first configuration information and second configuration information, and the terminal device receives the first configuration information and the second configuration information. Correspondingly, the terminal device configures the DRX inactivity timer of the first DRX and the DRX inactivity timer of the second DRX according to the first configuration information, and configures the first cell to the first DRX group and the second cell to the second DRX group according to the second configuration information.

[0152] The specific implementation method of step 1 here can refer to the specific implementation method of step 1 in the above method 1, which will not be repeated here.

[0153] Step 2: When the first DRX group is in the DRX activation time and the second DRX group is also in the DRX activation time, the network device sends second indication information on the first cell, and the terminal device receives the second indication information on the first cell.

[0154] Step 3: The terminal device starts or restarts the DRX inactivation timer of the second DRX according to the second indication information, so that the terminal device extends the DRX activation time of the second service cell.

[0155] It should be understood that the above-mentioned method 1 and method 2 can be implemented in combination with each other. When method 1 and method 2 are implemented in combination, when the terminal device is in the DRX activation time of the first DRX group and the second DRX group is in the DRX inactivation time, the terminal device starts the DRX inactivation timer of the second DRX according to the first indication information to start the activation time of the second DRX group; if the terminal device is in the DRX activation time of the first DRX group and the second DRX group is also in the DRX activation time, the terminal device starts / restarts the DRX inactivation timer of the second DRX according to the second indication information to extend the activation time of the second DRX group.

[0156] Similarly, for the DRX activation time of the first service cell, if the terminal device receives a physical downlink control channel PDCCH for indicating new data transmission on any service cell configured with the first DRX, it starts or restarts the DRX inactivation timer corresponding to the first DRX.

[0157] Optionally, the first indication information and the second indication information may actually be the same indication information, and the terminal device may realize different indication functions (the former may start the activation time of the second DRX and the latter may extend the activation time of the second DRX) based on the different times of receiving the indication information (i.e., the terminal device receives the indication information at the non-activation time or activation time of the second DRX) using the same indication information.

[0158] Method 3: The indication information is used to instruct the terminal device to end the DRX activation time of the second service cell of the terminal device.

[0159] like Fig.7D As shown, the network device can send a third indication message on the first service cell at the DRX activation time of the second service cell, and the third indication message is used to instruct the terminal device to stop the DRX inactivity timer (i.e., drx-InactivityTimer-2) corresponding to the second DRX. Correspondingly, the terminal device receives the third indication message on the first service cell at the DRX activation time of the second service cell, and then stops the DRX inactivity timer corresponding to the second DRX at the DRX activation time of the second service cell according to the third indication message, so as to end the DRX activation time of the second service cell and start the DRX inactivity time of the second service cell.

[0160] Combination Fig.7D The specific implementation process of the above method 3 may include the following steps:

[0161] Step 1: The network device sends first configuration information and second configuration information, and the terminal device receives the first configuration information and the second configuration information. Correspondingly, the terminal device configures the DRX inactivity timer of the first DRX and the DRX inactivity timer of the second DRX according to the first configuration information, and configures the first cell to the first DRX group and the second cell to the second DRX group according to the second configuration information.

[0162] The specific implementation method of step 1 here can refer to the specific implementation method of step 1 in the above method 1, which will not be repeated here.

[0163] Step 2: When the first DRX group is in the DRX activation time, and the second DRX group is also in the DRX activation time, and the DRX inactivation timer of the second DRX is in the running state, the network device sends the third indication information on the first cell, and the terminal device receives the third indication information on the first cell.

[0164] Step 3: The terminal device stops the DRX inactivation timer of the second DRX according to the third indication information, so that the DRX activation time of the second service cell of the terminal device ends and enters the DRX inactivation time.

[0165] Optionally, the third indication information may also be used to instruct the terminal device to stop the DRX duration timer corresponding to the second DRX (ie, drx-onDurationTimer-2).

[0166] It should be understood that mode 3 can be implemented in combination with the above-mentioned mode 1 (i.e., mode 1 is used to start drx-InactivityTimer-2 and mode 3 is used to stop drx-InactivityTimer-2), can be implemented in combination with the above-mentioned mode 2 (i.e., mode 2 is used to start / restart drx-InactivityTimer-2 and mode 3 is used to stop drx-InactivityTimer-2), and can also be implemented in combination with the above-mentioned modes 1 and 2 (i.e., modes 1 and 2 are used to start / restart drx-InactivityTimer-2 and mode 3 is used to stop drx-InactivityTimer-2), and there is no limitation here.

[0167] Optionally, the third indication information and the first / second indication information may be implemented through different states of the same indication information (referred to as the fourth indication information here for ease of description).

[0168] Example 1: The terminal device receives the fourth indication information in the first cell. When the fourth indication information is set to the first state and the second DRX group is in the DRX inactive time, the terminal device starts drx-InactivityTimer-2 in the second DRX group. When the fourth indication information is set to the second state and the second DRX group is in the DRX active time, the terminal device stops drx-InactivityTimer-2 in the second DRX group. When the terminal device is in the DRX active time in the first cell, if it receives a PDCCH indicating a new transmission on any service cell of the first DRX group, the terminal device starts or restarts drx-InactivityTimer-1.

[0169] Example 2: The terminal device receives the fourth indication information in the first cell. When the fourth indication information is set to the first state and the second DRX group is in the DRX activation time, the terminal device starts or restarts drx-InactivityTimer-2 in the second DRX group. When the fourth indication information is set to the second state and the second DRX group is in the DRX activation time, the terminal device stops the second DRX inactivity timer in the second DRX group. When the terminal device is in the DRX activation time in the first cell, if it receives a PDCCH indicating a new transmission on any service cell of the first DRX group, the terminal device starts or restarts the first DRX inactivity timer (i.e., drx-InactivityTimer-1).

[0170] One possible design is that different states of the fourth indication information are realized by different values ​​of the same information bit. For example, the fourth indication information is specifically the first bit of the DCI, and when the value of the first bit is 0 (or 1), it indicates that the fourth indication information is set to the first state, and when the value of the first bit is 1 (or 0), it indicates that the fourth indication information is set to the second state.

[0171] It should be understood that the third indication information and the first / second indication information may also be implemented through different indication information. For example, the first / second indication information is carried by DCI, and the third indication information is carried by PDSCH.

[0172] In a possible implementation manner of the present application, the network device may indicate the DRX state of another DRX service cell of the terminal device by sending indication information on any DRX service cell of the terminal device.

[0173] In this case, the first service cell can be the main service cell of the terminal device, and the second service cell can be the secondary service cell of the terminal device; or, the first service cell can be the secondary service cell of the terminal device, and the second service cell can be the main service cell of the terminal device; or, both the first service cell and the second service cell can be secondary service cells of the terminal device.

[0174] Optionally, cells in different DRX groups (ie, serving cells configured with different DRXs) may send indication information to each other to control the DRX state switching of the other party.

[0175] For example, after executing the above S602, the terminal device may also receive indication information sent by the network device on the third service cell of the terminal device, wherein the indication information sent by the network device on the third service cell is used to instruct the terminal device to start or extend or end the DRX activation time of the first service cell of the terminal device, and the terminal device starts or extends or ends the DRX activation time of the first service cell according to the indication information sent by the network device on the third service cell. The third service cell may be configured with a second DRX, and the third service cell may be the same cell as the second service cell, or may be a different cell, without limitation.

[0176] Which specific serving cell or cells in a DRX group the network device sends the above-mentioned indication information may be pre-defined by a protocol, or indicated by the network device sending configuration signaling or indication signaling.

[0177] In another possible implementation of the present application, the network device may indicate the DRX status of one or more secondary service cells of the terminal device by sending indication information on the primary service cell of the terminal device, but cannot send indication information on the secondary service cell to indicate the DRX status of the primary service cell. In this case, the first service cell is the primary service cell of the terminal device, and the second service cell is the secondary service cell of the terminal device.

[0178] In another possible implementation of the present application, the network device may send indication information on one or more cells in a DRX group of the terminal device to indicate the start, extension or end of the activation time corresponding to all other DRX groups. For example, the indication information sent by the network device on the above-mentioned first service cell is used to instruct the terminal device to start or extend or end the DRX activation time of the service cells corresponding to other DRXs in at least two DRXs except the first DRX, and the other DRXs include the second DRX.

[0179] For example, the network device configures the first cell with the first DRX, the second cell with the second DRX, and the third cell with the third DRX. The network device sends fifth indication information in the first cell, and the fifth indication information is used to instruct the terminal device to start, extend or end the DRX activation time in the second cell, and is also used to instruct the terminal device to start, extend or end the DRX activation time in the third cell.

[0180] The DRX group in which the network device sends the above-mentioned indication information, and the specific serving cell or cells in a DRX group, may be pre-defined by a protocol, or indicated by the network device sending configuration signaling or indication signaling.

[0181] Optionally, the various indication information involved in the embodiments of the present application may include the starting time when the terminal device starts, extends or ends the DRX activation time of the second service cell.

[0182] Exemplarily, each indication information as above includes the time when drx-InactivityTimer-2 is started / restarted / stopped, and the time may be a specific symbol, or a time slot, or a subframe, etc.

[0183] Optionally, the starting time when the terminal device starts, extends, or ends the DRX activation time of the second service cell may also be pre-defined by the protocol.

[0184] For example, the terminal device starts or restarts the drx-InactivityTimer-2 timer at the first OFDM symbol after receiving the first / second indication information, or the starting moment of the next time slot (or the starting OFDM symbol), or the starting moment of the time slot where the first / second indication information is located (or the starting OFDM symbol), or the ending moment of the time slot where the first / second indication information is located (or the ending OFDM symbol), or after a period of time after receiving the first / second indication information. The terminal device stops the drx-InactivityTimer-2 timer at the first OFDM symbol after receiving the third indication information, or the starting moment of the next time slot (or the starting OFDM symbol), or the starting moment of the time slot where the third indication information is located (or the starting OFDM symbol), or the ending moment of the time slot where the third indication information is located (or the ending OFDM symbol), or after a period of time after receiving the third indication information.

[0185] Optionally, various indication information involved in the embodiments of the present application can be carried in PDCCH (such as DCI) or carried in PDSCH (such as MAC CE signaling), which is not limited here.

[0186] When the indication information is carried in DCI, the DCI carrying the indication information may be a scheduling DCI or a non-scheduling DCI, which is not limited here.

[0187] Optionally, each indication information involved in the embodiments of the present application may include one or more information bits, which may be reserved bits in an existing DCI format (DCI format), or bits newly added to the existing DCI format, or one or more information fields in the existing DCI format may be reinterpreted, which is not limited here.

[0188] Optionally, the cyclic redundancy check (CRC) of the DCI carrying the indication information may be scrambled by a plurality of radio network temporary identifiers (RNTIs), for example, may include one or more of the following RNTIs: cell radio network temporary identifier (C-RNTI), modulation and coding scheme radio network temporary identifier (MCS-RNTI), configured scheduling radio network temporary identifier (CS-RNTI), and slot format indication radio network temporary identifier (SFI-RNTI).

[0189] Optionally, the various indication information involved in the embodiments of the present application can be configured by the network or specified by the protocol, which is not limited here.

[0190] The following introduces possible specific implementation methods of carrying the above indication information through DCI.

[0191] Implementation 1:

[0192] Implementation method 1 is directed to the first indication information in implementation method 1 as described above, that is, the first indication information indicates that the terminal device returns to the DRX activation time from the DRX inactive time on the second service cell.

[0193] The network device can send a dormancy indication (SCelldormancy indication) for the secondary service cell on the primary service cell (PCell), and the dormancy indication is used to instruct the terminal device to switch between the dormant bandwidth part (dormant BWP) and the non-dormant BWP (non-dormant BWP) on the SCell. At the DRX activation time, the DCI format 0_1 ​​and / or DCI format 1_1 sent by the network device may include the dormancy indication. Among them, both the scheduled DCI and the non-scheduled DCI can carry the dormancy indication. For example, when the scheduled DCI carries the dormancy indication, the DCI format 0_1 ​​and / or DCI format 1_1 can schedule data (such as the physical uplink shared channel (PUSCH) or PDSCH) and carry the dormancy indication at the same time. When the non-scheduled DCI carries the dormancy indication, the DCI format 1_1 is used to carry the dormancy indication, and the DCI format 1_1 is not used to schedule the PDSCH, and the DCI format 0_1 ​​is not used to carry the dormancy indication. A PDCCH that schedules data and carries a sleep indication is called a Case 1 PDCCH, and a PDCCH that carries a sleep indication but does not schedule data is called a Case 2 PDCCH.

[0194] Whether the scheduling DCI carries the sleep indication can be configured by the network device. If the network device configures one or more secondary cell groups, the scheduling DCI carries the sleep indication, and the sleep indication is represented by a bitmap in a scheduling DCI. The number of bits in the bitmap is equal to the number of configured secondary cell groups, and each bit of the bitmap corresponds one-to-one to the configured secondary cell group. If a bit is set to 0, it means that the secondary cell in the corresponding secondary cell group stays in the sleep BWP or switches to the sleep BWP. If a bit is set to 1, it means that the secondary cell in the corresponding secondary cell group stays in the current non-sleep BWP or switches from the sleep BWP to a non-sleep BWP.

[0195] If the terminal device detects DCI format 1_1, and the CRC of the DCI is scrambled by C-RNTI or MCS-RNTI, and the frequency domain resource assignment field (FDRA field) in the DCI is set to all 0s (for resource allocation type 0 or dynamically switched resource allocation) or all 1s (for resource allocation type 1 or dynamically switched resource allocation), then the DCI is a non-scheduled DCI carrying a sleep indication. The DCI includes a bitmap, and the bits in the bitmap correspond one-to-one to the configured secondary cells in a certain order. If a bit is set to 0, it means that the corresponding secondary cell stays in the sleep BWP or switches to the sleep BWP. If a bit is set to 1, it means that the corresponding secondary cell stays in the current non-sleep BWP or switches from the sleep BWP to a non-sleep BWP.

[0196] In this manner, the first service cell is a primary service cell (PCell) configured with a first DRX, the second service cell is a secondary service cell configured with a second DRX, and the service cell configured with the second DRX may also include other secondary service cells except the second service cell.

[0197] It should be understood that when the service cell configured with the second DRX is configured in a secondary cell group, the network device can send a sleep indication to the service cell through Case 1 PDCCH. When all service cells configured with the second DRX are not configured in any secondary cell group, the DCI of Case 1 PDCCH sent by the network device does not include a sleep indication for the service cell configured with the second DRX. However, Case 2 PDCCH includes a sleep indication for the service cell configured with the second DRX.

[0198] When the first DRX group is in the DRX activation time and the second DRX group is in the DRX inactivation time, one or more information bits in the dormancy indication information field of the serving cell corresponding to the second DRX group in the DCI of Case 1 and / or Case 2 PDCCH are used to carry the first indication information. When the one or more information bits are set to the first state, they are used to indicate that the drx-InactivityTimer-2 of the second DRX group is started, and when the one or more information bits are set to the second state, they are used to indicate that the drx-InactivityTimer-2 of the second DRX group is not started.

[0199] If the one or more information bits are set to the first state, indicating that the drx-InactivityTimer-2 of the second DRX group is started. Then, if the secondary service cell corresponding to the one or more information bits is currently located in a dormant BWP, it switches from the dormant BWP to a non-dormant BWP, for example, switches to a non-dormant BWP specified by the network device through configuration information; if it is currently located in a non-dormant BWP, it continues to stay in the current non-dormant BWP or switches to another non-dormant BWP, for example, switches to a non-dormant BWP specified by the network device through configuration information. Optionally, the dormancy indication information bits of the service cell corresponding to the second DRX group in the DCI of Case 1 and / or Case 2 PDCCH, except for the one or more information bits, can still indicate the dormancy behavior of the corresponding secondary cell according to the above rules, that is, whether to switch between the dormant BWP and the non-dormant BWP.

[0200] It should be understood that the sleep indication information field of the serving cell corresponding to the first DRX group in the DCI of the PDCCH of Case 1 and / or Case 2 is still used to indicate the sleep behavior of the corresponding secondary cell.

[0201] If the one or more information bits are set to the second state, indicating that the drx-InactivityTimer-2 of the second DRX group is not started, the serving cell of the second DRX group may stay in the current BWP, or switch to the dormant BWP (if the current BWP is the dormant BWP, it continues to stay in the dormant BWP).

[0202] When the first DRX group is in the DRX activation time and the second DRX group is also in the DRX activation time, the sleep indication information field of the service cell corresponding to the second DRX group in the DCI of Case 1 and / or Case 2 PDCCH is still used to indicate the sleep behavior of the corresponding secondary cell, that is, whether to switch between sleep BWP and non-sleep BWP.

[0203] The specific information bits of the one or more information bits used to represent the first indication information in Case 1 and / or Case 2 PDCCH may be configured or indicated by a network device, or predefined by a protocol, for example, the protocol predefines certain rules to determine the one or more information bits.

[0204] Exemplarily, for Case 1 PDCCH, if the service cell in the second DRX group is configured with only one secondary cell group, the sleep indication information bit in the DCI corresponding to the secondary cell group is used to carry the first indication information. If the service cell in the second DRX group is configured with multiple secondary cell groups, the sleep indication information bit corresponding to the secondary cell group with the largest or smallest secondary cell group number among the multiple secondary cell groups configured by the service cell in the second DRX group is used to carry the first indication information. For Case 2 PDCCH, in the sleep indication information field of the service cell corresponding to the second DRX group in the DCI of Case 2 PDCCH, the sleep indication information bit corresponding to the service cell with the largest or smallest service cell number among the service cells of the corresponding second DRX group is used to carry the first indication information.

[0205] In this implementation, the network device may configure or indicate, or the protocol may predefine which specific PDCCH carries the first indication information, for example, only Case 1 PDCCH carries the first indication information, or only Case 2 PDCCH carries the first indication information, or both Case 1 and Case 2 PDCCH carry the first indication information.

[0206] Implementation 2:

[0207] In this implementation, the primary service cell PCell is configured with the first DRX. If the network device is configured with the second DRX, the service cell configured with the second DRX does not configure the sleep indication function or does not activate the sleep indication function. For example, the service cell configured with the second DRX is not configured in any secondary cell group. In addition, the network device configuration or protocol stipulates that the DCI of Case 2 PDCCH does not include the sleep indication bit for the service cell in the second DRX group. In other words, the service cell configured with the second DRX does not configure the sleep BWP. The present application does not limit whether the service cell configured with the first DRX is configured with the sleep indication function.

[0208] For details on how to implement the first / second / third indication information, please refer to the above description and will not be repeated here.

[0209] The various implementations in the embodiments of the present application can be combined with each other to achieve different technical effects.

[0210] From the above, it can be known that the network device in the embodiment of the present application can indicate the DRX state of another DRX based on one DRX (i.e., cross-DRX group or cross-carrier indication), and can more flexibly control the DRX state of the terminal device in different DRX (or different subcarriers). When data arrives, other DRXs can be returned to the DRX activation time to monitor PDCCH, thereby improving the throughput of the terminal device and reducing data latency; when there is no data, other DRXs can be maintained or returned to the DRX inactive time, so that the terminal device can shut down the RF link corresponding to other DRXs, thereby saving power consumption.
