Description

Communication method and communication device based on wakeup configuration

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and a communication device based on wake-up configuration.

Background

In a wireless communication system, in order to reduce power consumption of a terminal device and thereby increase battery usage time, a network device may configure a discontinuous reception (discontinuous reception, DRX) mechanism and a Wake Up Signal (WUS) mechanism for the terminal device. The DRX mechanism is to configure a DRX cycle (DRX cycle) for the UE, and one DRX cycle may include a duration (on duration) and a sleep period (opportunity for DRX). In the duration time, the terminal equipment normally monitors PDCCH; in the sleep period, the terminal device enters a sleep state without receiving the PDCCH to reduce power consumption. The WUS mechanism indicates whether to skip PDCCH listening for a duration in the next long DRX cycle through WUS.

The extended reality (XR) technology has the advantages of multiple viewing angles, strong interactivity and the like, can provide a brand new visual experience for users, and has great application value and commercial potential. XR includes Virtual Reality (VR), augmented reality (augmented reality, AR), cloud Game (CG), and the like. In general, for XR transmission traffic and video transmission traffic, the traffic model is usually arrived periodically according to the frame rate. The XR traffic data arrival period is non-integer and the DRX periods are integers in milliseconds, so that multiple durations may be configured in a long period to match the DRX period to the XR traffic arrival time.

However, in the case of configuring a plurality of duration periods in one long period, if WUS information indicates to skip PDCCH monitoring of duration periods in the long period, the terminal device skips PDCCH monitoring of a plurality of duration periods in the long period, resulting in a large data transmission delay.

In order to facilitate understanding of the technical scheme of the present application, the following description refers to related technical terms related to the present application.

1. Discontinuous reception (discontinuous reception, DRX) cycle

A discontinuous reception (discontinuous reception, DRX) mechanism is introduced in the 5G new radio, NR, standard. The DRX mechanism is to configure a DRX cycle (DRX cycle) for the UE, and one DRX cycle may include a duration (on duration) and a sleep period (opportunity for DRX). As shown in fig. 1, during the duration, the UE normally listens to the PDCCH; during opportunity for DRX, the UE has an opportunity to enter a sleep state without receiving the PDCCH to reduce power consumption. Note that the UE in sleep period only does not receive PDCCH, but may receive data from other physical channels, such as physical downlink shared channel (physical downlink SHARED CHANNEL, PDSCH), acknowledgement information (ACK), etc. For example: in semi-PERSISTENT SCHEDULING (SPS), a UE in a sleep period may receive PDSCH data transmitted on periodically configured downlink subframes.

Illustratively, the DRX cycle may include a long DRX cycle (long DRX cycle) and a short DRX cycle (short DRX cycle). As shown in fig. 2, the period value of the long DRX cycle is longer than the period value of the short DRX cycle. Illustratively, the period value of the long DRX cycle is an integer multiple of the period value of the short DRX cycle. The long DRX cycle can reduce power consumption of the terminal device, which is beneficial to prolonging battery usage time of the terminal device, and the short DRX cycle can reduce scheduling delay, which is beneficial to accelerating response speed of the terminal device. For example, in order to meet the requirements of the battery usage time and the response speed of the terminal device, the terminal device may configure both the long DRX cycle and the short DRX cycle. In general, the terminal device uses one of the configuration of the long DRX cycle and the short DRX cycle at the same time.

Illustratively, the DRX cycle is configured by the network device. For example, the network device may signal the DRX-Config configuration through radio resource control (radio resource control, RRC). Illustratively, the network device may control DRX of the terminal device by configuring the following parameters: the DRX long period start offset (DRX-LongCycleStartOffset) includes two parameters, namely a DRX long period (DRX-LongCycle) and a DRX start offset (DRX-StartOffset), where DRX-LongCycle represents the period value of the DRX long period and DRX-StartOffset represents the offset of the DRX long period, which together determine the start subframe of the DRX long period. The DRX short cycle (DRX-ShortCycle) represents a cycle value of the DRX short cycle. The DRX short period timer (DRX-ShortCycleTimer) is used to configure the number of DRX short periods. The DRX Duration timer (DRX-onduration timer) is used to configure the Duration of the Duration period, and the DRX slot offset (DRX-SlotOffset) is used to configure the delay of DRX-onduration timer start, i.e. DRX-SlotOffset after the start of an On Duration subframe in a DRX cycle. drx-SlotOffset is the offset within a subframe, less than 1 millisecond (millisecond, ms).

2. PDCCH-based Wake Up Signal (WUS)

WUS is associated with a DRX long cycle for indicating whether to skip PDCCH monitoring for a duration in the next DRX long cycle after WUS is received. WUS is carried by downlink control information (downlink control information, DCI) in format2_6 (DCIformat 2_6) with cyclic redundancy check (cyclic redundancy check, CRC) being identified by a power saving radio network temporary identity (power saving radio network temporary identifier, PS-RNTI). The configuration information of WUS may include the following parameters:

A Power Save (PS) Offset (PS-Offset) for indicating a starting listening time of the DCI format 2_6, i.e., a period of time before a duration of a long period from the DRX. Listening to DCI format 2_6 is stopped at a minimum offset (minimum offset) before the DRX long cycle duration, the minimum offset being related to the capability of the terminal device. For example, the ps-Offset is 2ms, which indicates that the start time of the listening DCI format 2_6 is 2ms from the start time of the duration of the DRX long cycle. The terminal device starts listening to DCI format 2_6 2ms before the start time of the duration of the DRX long cycle.

DCI2_6 length (sizeDCI-2_6) for indicating the length of DCI format 2_6.

DCI2_6 position (ps-PositionDCI-2_6) for indicating the position of the bit corresponding to the terminal device in DCI format 2_6. Illustratively, the DCI format 2_6 includes information of a plurality of terminal devices, and the information of each UE is located in a different location of the DCI format 2_6. In DCI format 2_6, one bit may correspond to one terminal device. The terminal may thus be able to determine the position of the terminal in DCI format 2_6 by means of the parameter ps-PositionDCI-2_6.

Ps wake-up information (ps-wake) indicating a default behavior of the terminal device when WUS information is not monitored. For example, when the terminal device is configured to monitor DCI format 2_6, but does not receive the corresponding WUS information, the terminal device determines whether to monitor the PDCCH based on ps-wake.

Illustratively, the terminal device corresponds to a bit in DCI format 2_6 indicating whether the terminal device skips PDCCH monitoring for a duration of the next long period after receiving WUS information, the position of the bit being determined by ps-PositionDCI-2_6. For example, when the bit value is 1, the UE normally listens to the PDCCH for a duration of the next long period; when the bit value is 0, the UE skips PDCCH monitoring for a duration in the next long period. For example, the terminal device may monitor DCI format 2_6 during the DRX sleep period. As shown in fig. 3, the value of a bit (shown in gray boxes in fig. 3) corresponding to the terminal device in DCI format 2_6, which the terminal device monitors before the first duration, is 1, and the terminal device monitors the PDCCH for the first duration. The value of the bit corresponding to the terminal equipment in the DCI format 2_6 monitored by the terminal equipment before the second duration is 0, and the terminal equipment does not monitor the PDCCH in the second duration.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a communication system according to an embodiment of the present application. As shown in fig. 4, the communication system may include at least one network device and at least one terminal device, and fig. 4 shows one network device and two terminal devices. The network device provides communication services to the terminal device. The network device may include a baseband unit (BBU) and a remote radio unit (remote radio unit, RRU). The BBU and RRU may be placed in different places, for example: RRU draws far, places in the region of high traffic, and BBU places in the central computer lab. The BBU and RRU may also be placed in the same machine room. The BBU and RRU may also be different components under one rack.

In the above communication system, in order to reduce the scheduling delay, the terminal device listens to the downlink control signaling (downlink control information, DCI) of the base station every time slot in order to receive the uplink grant or downlink data. Since the terminal device does not know the specific transmission position of the physical downlink control channel (physical downlink control channel, PDCCH) carrying DCI, blind detection can only be performed on a preconfigured search space, which consumes the electric quantity of the terminal device. In order to reduce the power consumption of the terminal device, when there is no data transmission, the power consumption can be reduced by stopping receiving the PDCCH (i.e. stopping PDCCH blind detection), so as to improve the battery service time.

In order to reduce power consumption of the terminal device and thereby improve battery usage time, the network device may configure the terminal device with a DRX mechanism and a WUS mechanism. For example, the network device may configure the UE with both a long DRX cycle and a short DRX cycle, where both the long DRX cycle and the short DRX cycle are integer milliseconds.

In some scenarios, multiple duration periods may be configured within one long DRX cycle in order to enable the DRX cycle to match traffic transmissions. For example, for extended reality (XR) transmission services and video transmission services, the service model thereof is usually arrived periodically according to the frame rate. The XR traffic data arrival period is non-integer and the DRX periods are integers in milliseconds, so that multiple durations may be configured in a long period to match the DRX period to the XR traffic arrival time.

However, the WUS mechanism is not applicable to the above scenario where multiple durations are configured within one long DRX cycle. For example, when WUS information indicates that PDCCH monitoring of a duration within a long DRX cycle is skipped, a terminal device may skip PDCCH monitoring of a plurality of durations within the long DRX cycle, resulting in a large data transmission delay.

In other scenarios, to enable the DRX cycle to be matched to traffic transmissions, multiple DRX cycles may be configured that may be activated simultaneously, each DRX cycle may have a different starting offset. For example, as shown in fig. 5, when XR video transmission traffic arrives at a frame every 16.67ms, three DRX cycles (DRX-1, DRX-2, and DRX-3, respectively) may be configured for the terminal device, each DRX cycle has a length of 50ms, and starting offsets of the three DRX cycles are t+0ms, t+16ms, and t+33ms, respectively. Wherein T is used to align the duration of the first DRX cycle with the XR traffic arrival time. However, according to the current WUS mechanism, only one WUS configuration cannot be adapted to the scenario of multiple simultaneously active DRX configurations.

In view of this, embodiments of the present application provide a communication method and a communication device, which can reduce data transmission delay. The method provided by the embodiment of the application can be applied to the communication system shown in fig. 4. Or the method may be applied to a terminal device, which may be the terminal device described above, and a network device. The network device may be the network device described previously.

Referring to fig. 6, fig. 6 is an interaction schematic diagram of a communication method according to an embodiment of the present application.

It will be appreciated that the interaction diagram in the present application is illustrated by taking the network device and the terminal device as the execution body of the interaction diagram as an example, but the present application is not limited to the execution body of the interaction diagram. For example, the network device in the interaction diagram may also be a chip, a system on a chip, or a processor supporting the network device to implement the method, or may also be a logic node, a logic module, or software capable of implementing all or part of the functions of the network device; the terminal device in the interaction diagram may also be a chip, a system-on-chip, or a processor supporting the terminal to implement the method.

As shown in fig. 6, the method includes, but is not limited to, the following steps.

601, The network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information, where the first configuration information configures a listening time of wake-up indication information, where the wake-up indication information indicates whether to listen to a PDCCH in each of N duration periods in a DRX cycle, and N is a positive integer greater than 1.

Illustratively, the N duration periods of the DRX cycle may be configured by the network device. For example, the network device may configure N DRX start offsets (StartOffset) in the DRX cycle from which to determine the start subframes of the N duration periods. For example, as shown in fig. 7, the DRX cycle is 50ms, and the network device configures three DRX start offsets in the DRX cycle, 0ms,16ms,33ms, respectively.

As another example, the network device may be configured with a DRX cycle pattern (pattern) that includes N DRX small cycles (INNER CYCLE) that are sequentially active in the DRX cycle. Wherein each DRX cycle includes a duration in which the terminal device listens to the PDCCH and a sleep period in which the terminal device does not listen to the PDCCH. For example, as shown in fig. 8, the DRX cycle is 50ms, and the DRX cycle pattern includes three DRX small cycles of 16ms,17ms, and 17ms, respectively. The three DRX cycles are sequentially active, thus constituting one DRX cycle of 50 ms. In the present application, the "DRX small cycle" may alternatively be described as "DRX inner cycle". It should be understood that the DRX cycle is merely a term for a period of time including one duration and one sleep period in the DRX cycle, and the present application is not limited to the term for a period of time including one duration and one sleep period in the DRX cycle.

In the present application, the duration of the N duration periods may be the same or different, and the N duration periods may be uniformly distributed or unevenly distributed in the DRX cycle.

The first configuration information is illustratively used for configuring wake-up indication information corresponding to the N duration periods in the DRX cycle. For example, the first configuration information may include an offset for indicating a start time of a listening time of the wake-up indication information, i.e., an offset for indicating a start subframe of the listening time.

Illustratively, the wake-up indication information may be carried by DCI format 2_6. For example, the wake-up indication information may include one or more bits corresponding to the terminal device in the DCI format 2_6. The first configuration information may further include a DCI2_6 length and a DCI2_6 position, and the terminal device may determine a position of one or more bits corresponding to the terminal device in the DCI format 2_6 based on the DCI2_6 length and the DCI2_6 position.

In the present application, the wake-up indication information may alternatively be described as a "wake-up signal", "wake-up information", or the like. It is understood that the wake-up indication information is merely a name of information for indicating whether to monitor the PDCCH in each of N duration periods in the DRX cycle in the present application, and the present application is not limited to the name of information for indicating whether to monitor the PDCCH in each of N duration periods in the DRX cycle.

The network device sends a wake-up indication message based on the listening time configured by the first configuration information, and the terminal device listens for the wake-up indication message based on the listening time configured by the first configuration information, 602.

In an exemplary embodiment, the network device sends wake-up indication information in a listening time configured by the first configuration information, the terminal device listens to the wake-up indication information in the listening time configured by the first configuration information, and determines whether to listen to the PDCCH in the N duration periods based on the monitoring of the wake-up indication information. For example, the terminal device may determine whether to monitor the PDCCH for the N duration periods based on whether to monitor the wake-up indication information. The terminal device may determine to monitor the PDCCH for N duration periods if the wake-up indication information is monitored, and determine not to monitor the PDCCH for N duration periods if the wake-up indication information is not monitored. Or the terminal device may determine not to monitor the PDCCH for N duration periods if the wake-up indication information is monitored, and determine to monitor the PDCCH for N duration periods if the wake-up indication information is not monitored. As another example, the terminal device may determine whether to monitor the PDCCH for N duration periods based on the value indicated by the monitored wake-up information.

In the embodiment of the application, under the condition that the DRX period comprises N duration periods, the corresponding wake-up indication information can be configured for each duration period in the N duration periods, so that the terminal equipment can skip PDCCH monitoring in a single duration period in the N duration periods based on the wake-up indication information, and the power consumption of the terminal equipment can be reduced while the influence of data transmission is reduced.

In some possible implementations, the method shown in fig. 6 further includes step 603.

603, The network device sends second configuration information, and correspondingly, the terminal device receives the second configuration information, and the second configuration information configures the second configuration information to configure the N duration periods.

The second configuration information may be configuration information of the DRX cycle, through which the network device may configure listening of N duration periods and wake-up indication information in the DRX cycle. For example, the second configuration information may include N DRX start offsets by which the network device configures the start subframes of the N duration periods. As another example, the second configuration information may include a DRX cycle pattern including N DRX small cycles that are sequentially active in the DRX cycle.

Illustratively, the second configuration information may further include a period value of the DRX cycle, a duration of the N duration periods, and the like.

In one possible implementation, the second configuration information may include first indication information for indicating interception of wake-up indication information. The first indication information is used for indicating whether to monitor wake-up indication information corresponding to the N duration periods in the DRX cycle.

For example, in case that the first indication information indicates the first value, the first indication information indicates wake-up indication information corresponding to N duration periods in the listening DRX cycle. And under the condition that the first indication information indicates the second value, the first indication information indicates that the wake-up indication information corresponding to the N duration periods is not monitored. The first value may be "1" or "enable" and the second value may be "0" or other values, as the application is not limited.

In such an implementation, step 602 may be replaced with: the network device sends wake-up indication information based on the monitoring time configured by the first configuration information and the second configuration information, and the terminal device monitors the wake-up indication information based on the monitoring time configured by the first configuration information and the second configuration information.

For example, the terminal device may determine whether to monitor the wake-up indication information based on the first indication information carried in the second configuration information. And if the first indication information indicates the first value, the terminal equipment monitors the wake-up indication information in the monitoring time, and determines whether to monitor the PDCCH in the N duration periods based on the wake-up indication information. And under the condition that the first indication information indicates the second value, the terminal equipment does not monitor the wake-up indication information and monitors PDCCH in the N duration time periods.

For example, in case that the first indication information is not included in the second configuration information, the terminal device may not monitor the wake-up indication information and monitor the PDCCH for the N duration periods.

In the embodiment of the present application, "sending information to … (terminal)" may be understood that the destination terminal of the information is a terminal, and may include directly or indirectly sending information to the terminal. "receiving information from … (a terminal)" is understood to mean that the source of the information is the terminal, and may include receiving information directly or indirectly from the terminal. The information may be processed as necessary between the source and destination of the information transmission. For example, the information may be encoded, modulated, power matched, resource mapped, or the like at the source of the information transmission. For example, the destination end receiving the information may perform one or more of demapping, demodulating, decoding, and the like on the information. Similar expressions in the present application are understood similarly, and are not repeated here.

Referring to fig. 9, fig. 9 is an interaction schematic diagram of another communication method according to an embodiment of the present application. As shown in fig. 9, the method includes, but is not limited to, the following steps.

901, The network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information, the first configuration information configures N sections of monitoring time of wake-up indication information, and wake-up indication information monitored in each section of monitoring time in the N sections of monitoring time indicates whether to monitor the PDCCH in each of N duration periods in the DRX cycle.

Illustratively, the DRX cycle includes N duration periods, which may be understood as a DRX cycle configured with N DRX start offsets or DRX small cycles. The first configuration information is used for indicating that wake-up indication information is monitored before each DRX initial offset or a duration period corresponding to each DRX small period.

Illustratively, the first configuration information may indicate a start time (i.e., a start time domain position) of each of the N listening times. For example, the first configuration information includes N pieces of time information, each of the N pieces of time information indicating a start time of each of the N pieces of listening time. As another example, the first configuration information includes time information indicating a time difference of a start time of each of the N listening times compared to a start time of a corresponding one of the N duration times.

And 902, the network equipment sends wake-up indication information based on the monitoring time configured by the first configuration information, and correspondingly, the terminal equipment monitors the wake-up indication information based on the monitoring time configured by the first configuration information.

The network device may send wake-up indication information in the N-segment listening time, and the terminal device listens for the wake-up indication information in the N-segment listening time, respectively.

The first configuration information includes an offset (offset) indicating a time difference of a start time of each of the N listening times compared to a start time of a corresponding one of the N duration times. The end time of the N-segment listening time is determined by a minimum offset indicating a time difference of the end time of each segment listening time from the start time of the corresponding duration. The minimum offset is related to the capabilities of the terminal device.

For example, a first listening time of the N-segment listening times is used to indicate whether to listen to the PDCCH for a first duration of the N durations, the offset is used to indicate a time difference between a start time of the first listening time and a start time of the first duration, and the minimum offset is used to indicate a time difference between an end time of the first listening time and a start time of the first duration. As shown in fig. 10, the terminal device starts listening for the wake-up indication information at an offset before each duration and stops listening for the wake-up indication information at a minimum offset before each duration.

In some possible implementations, the method shown in fig. 9 may further include step 903 or step 904.

If the terminal device monitors the first wake-up indication information in a first monitoring time in the N monitoring times, 903, determining whether to monitor the PDCCH in a first duration in the N durations based on a value indicated by the first wake-up indication information.

The first duration may be, for example, a next duration after the first listening time. In the case that the first wake-up indication information indicates the third value, the first wake-up indication information indicates that the PDCCH is not monitored in the first duration, and the terminal device does not start a duration timer (onduration timer) corresponding to the first duration. And under the condition that the first indication information indicates the fourth value, the first wake-up indication information indicates to monitor the PDCCH in the first duration, the terminal equipment starts a duration timer corresponding to the first duration, the timing duration of the duration timer is the duration of the first duration, and the starting time of the duration timer is the starting time of the first duration.

For example, the first wake-up indication information may include a bit, and the terminal device may monitor the PDCCH for a first duration based on a value of the bit. The third value may be 1, and the fourth value may be 0. In the present application, the bit may be called a Wake-up indication bit (Wake-up indication bit), and if the value of the Wake-up indication bit in the monitored Wake-up indication information is 1, the terminal device starts a duration timer corresponding to the next duration period after the Wake-up indication information is monitored; and under the condition that the value of the wake-up indication bit in the monitored wake-up indication information is 0, a duration timer corresponding to the next duration period after the wake-up indication information is monitored is not started.

For example, the first wake-up indication information is carried in DCI2_6, the first configuration information may further include a DCI2_6 length and a DCI2_6 position, and the terminal device may determine the position of the bit in DCI format 2_6 based on the DCI2_6 length and the DCI2_6 position. As shown in fig. 10, the bit corresponding to the terminal device in DCI format 2_6, which is monitored by the terminal device before the first duration of the DRX cycle, is 1, and the terminal device monitors the PDCCH during the first duration.

And 904, if the terminal equipment does not monitor the first wake-up indication information in the first monitoring time in the N monitoring times, determining whether to monitor the PDCCH in the first duration in the N duration based on the first configuration information.

The first configuration information also configures a default behavior of the terminal device, indicating whether the terminal device listens to the PDCCH for a corresponding duration without listening to the wake-up indication information. And the terminal equipment determines whether to monitor the PDCCH in the first duration period or not based on the default behavior configured by the first configuration information under the condition that the first wake-up indication information is not monitored.

For example, the first configuration information indicates that the terminal device does not monitor the PDCCH for a corresponding duration in case that the wake-up indication information is not monitored. And the terminal equipment does not monitor the PDCCH in the first duration period under the condition that the first wake-up indication information is not monitored.

Referring to fig. 11, fig. 11 is an interaction schematic diagram of another communication method according to an embodiment of the present application. As shown in fig. 11, the method includes, but is not limited to, the following steps.

1101, The network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information, where the first configuration information configures a period of listening time of wake-up indication information, and the wake-up indication information that is listened in the listening time indicates whether to listen to the PDCCH in each of N duration periods in the DRX cycle.

The first configuration information may indicate that the terminal device listens for wake-up indication information before the first duration of the DRX cycle.

Illustratively, the first configuration information may include a start time of the listening time. For example, the first configuration information may include an offset indicating a time difference of a start time of the listening time and a start time of the first duration in the DRX cycle.

1102, The network device sends wake-up indication information based on the listening time configured by the first configuration information, and correspondingly, the terminal device listens for the wake-up indication information based on the listening time configured by the first configuration information.

If the terminal device listens to the wake-up indication information in the listening time 1103, it is determined whether to listen to the PDCCH in each of the N duration periods based on the N bits included in the wake-up indication information.

Illustratively, each of the N bits included in the wake-up indication information indicates whether to listen to the PDCCH for each of N duration periods in the DRX cycle, respectively. For example, a first bit of the N bits is used to indicate whether to listen to the PDCCH for a first duration of the N durations. In case that the value of the first bit is 1, the first bit indicates that the PDCCH is monitored in a first duration, and the terminal device starts a duration timer corresponding to the first duration. And under the condition that the value of the first bit is 0, the first bit indicates that the PDCCH is not monitored in the first duration period, and the terminal equipment does not start a duration timer corresponding to the first duration period. Illustratively, the first bit may be a kth bit of the N bits, the first duration may be a kth duration of the N durations, and K is a positive integer less than N.

For example, as shown in fig. 12, the DRX cycle includes 3 duration periods, i.e., n=3, and the terminal device may monitor DCI format 2_6 before the first duration period, where the wake-up indication information corresponding to the terminal device includes 3 bits in the DCI format 2_6. The values of the three bits are 1,0 and 1 respectively, and the terminal device listens to the PDCCH in the first duration and the third duration, and does not listen to the PDCCH in the second duration.

1104, In case that the terminal device does not monitor the wake-up indication information in the listening time, determining whether to monitor the PDCCH in each of the N duration periods based on the first configuration information.

The first configuration information also configures a default behavior of the terminal device, indicating whether the terminal device listens to the PDCCH for N duration periods without listening to the wake-up indication information.

For example, the first configuration information may indicate the terminal device to monitor the PDCCH for N duration periods without receiving the wake-up indication information. Or the first configuration information may indicate that the terminal device does not monitor the PDCCH for N duration periods in case that the wake-up indication information is not received. Or the first configuration information may indicate the terminal device to monitor the PDCCH in M duration periods of the N duration periods under the condition that the wake-up indication information is not received, where M is a positive integer less than or equal to N. Illustratively, the M time durations are evenly distributed among the N time durations.

Referring to fig. 13, fig. 13 is an interaction schematic diagram of another communication method according to an embodiment of the present application. As shown in fig. 13, the method includes, but is not limited to, the following steps.

1301, The network device sends second configuration information, and correspondingly, the terminal device receives the second configuration information, where the second configuration information is used to configure a DRX cycle and monitoring of wake-up indication information corresponding to the DRX cycle, where the wake-up indication information is used to indicate whether to monitor a PDCCH in a duration of the DRX cycle.

The second configuration information may include a DRX-Config configuration parameter, by which the second configuration information may configure the DRX cycle. The DRX-Config configuration parameter may include at least one of a DRX start offset (DRX-startoffset), a DRX duration timer (DRX-onduration timer), and a DRX sleep time timer (DRX-inactivity timer). The DRX start offset is used for configuring the start time domain position of the duration of the DRX cycle, the DRX duration timer is used for configuring the length of the duration of the DRX cycle, and the DRX sleep time timer is used for configuring the length of the sleep period of the DRX cycle.

For example, the second configuration information may include first indication information, where the first indication information is used to indicate whether to monitor wake-up indication information corresponding to the DRX cycle, that is, the first indication information is used to indicate whether the WUS mechanism acts on the DRX cycle.

For example, in case the first indication information indicates a first value, the first indication information indicates wake-up indication information corresponding to a listening DRX cycle, i.e. the first indication information indicates that a WUS mechanism acts on the DRX cycle. And under the condition that the first indication information indicates the second value, the first indication information indicates that the wake-up indication information corresponding to the DRX period is not monitored, namely the first indication information indicates that the WUS mechanism does not act on the DRX period. The first value may be "1" or "enable" and the second value may be "0" or other values, as the application is not limited.

Illustratively, the value of the first indication information may be configured by a power saving downlink control information (DCI WITH CRC scrambled by PS _rnti, DCP) configuration indication (DCP-ConfigIndicator) in the DRX-Config configuration parameter.

The terminal device listens for wake-up indication information based on the second configuration information 1302.

For example, the terminal device may monitor the wake-up indication information based on the value of the first indication information. For example, in case the first indication information indicates a first value, the terminal device listens for the wake-up indication information for the listening time and determines whether to listen for the PDCCH for the duration of the DRX cycle based on the wake-up indication information. And under the condition that the first indication information indicates the second value, the terminal equipment does not monitor the wake-up indication information and monitors the PDCCH in the duration of the DRX period.

In one possible implementation, in case the second configuration information does not include the first indication information, the terminal device may not monitor the wake-up indication information and monitor the PDCCH for the duration of the DRX cycle.

For example, the network device may configure a plurality of DRX cycles for the terminal device, and indicate whether to monitor wake-up indication information corresponding to the plurality of DRX cycles through configuration information of each DRX cycle, respectively. For example, the terminal device may determine whether to monitor wake-up indication information of a corresponding DRX cycle according to first indication information in configuration information of each DRX cycle. The configuration information of the wake-up indication information corresponding to the multiple DRX cycles may be the same, that is, the network device may configure the terminal device with the multiple DRX cycles and the configuration information of one wake-up indication information, and the terminal device determines whether to monitor the wake-up indication information before the duration of the corresponding DRX cycle based on the first indication information in the configuration information of each DRX cycle.

For example, as shown in fig. 14, the network device may configure the terminal device with 2 DRX cycles, DRX cycle 1 and DRX cycle 2, respectively. The first indication information in the configuration information of the DRX cycle 1 indicates the second value or the configuration information of the DRX cycle 1 does not include the first indication information, the terminal device does not monitor the wake-up indication information corresponding to the DRX cycle 1, and monitors the PDCCH in the duration of the DRX cycle 1. The first indication information in the configuration information of the DRX cycle 2 indicates a first value, and the terminal device may monitor wake-up indication information corresponding to the DRX cycle 2 during a listening time (shown with a gray frame in fig. 14) configured by the first configuration information, and determine whether to listen to the PDCCH during a duration of the DRX cycle 2 based on the wake-up indication information corresponding to the DRX cycle 2.

For example, the period values of a plurality of DRX periods configured by the network device for the terminal device may be the same, and the start offsets of the plurality of DRX periods may be different. For example, the network device configures the terminal device with DRX cycle 1 and DRX cycle 2, the cycle values of DRX cycle 1 and DRX cycle 2 are each 50ms, the start offset of DRX cycle 1 is 0ms, and the start offset of DRX cycle 2 is 20ms. As shown in fig. 14, the duration corresponding to 0ms is the duration of DRX cycle 1, and the terminal device does not monitor the wake-up indication information before the duration corresponding to 0ms. The duration corresponding to 20ms is the duration of DRX cycle 2, and the terminal device listens for the wake-up indication information before the duration corresponding to 20ms.

In one possible implementation, the second configuration information configures N duration periods in the DRX cycle, N being a positive integer greater than 1. The method shown in fig. 13 further comprises step 1303.

1303, The network device sends first configuration information, and correspondingly, the terminal device receives the first configuration information, where the first configuration information configures a listening time of wake-up indication information, where the wake-up indication information indicates whether to listen to the PDCCH in each of N duration periods.

It is understood that, for a specific description of the listening time of the first configuration information and the wake-up indication information, reference may be made to the description related to step 601 in fig. 6 or step 901 in fig. 9 or step 1101 in fig. 11, which will not be described in detail here.

In such an implementation, step 1302 may be replaced with: the terminal equipment monitors wake-up indication information based on the monitoring time configured by the first configuration information and the second configuration information. I.e. the terminal device may determine whether to listen for the wake-up indication information based on the second configuration information. And under the condition that the second configuration information indicates to monitor the wake-up indication information, the terminal equipment monitors the wake-up indication information within the monitoring time configured by the first configuration information.

The foregoing details of the method according to the embodiments of the present application and the apparatus according to the embodiments of the present application are provided below.

According to the method embodiment of the application, the communication device is divided into the functional modules, for example, each functional module can be divided corresponding to each function, and two or more functions can be integrated into one processing module. The integrated modules may be implemented in hardware or in software functional modules. It should be noted that, the division of the modules in the present application is illustrative, and is merely a logic function division, and other division manners may be implemented in practice. The communication device of the embodiment of the present application will be described in detail below with reference to fig. 15 to 17.

Fig. 15 is a schematic structural diagram of a communication device according to an embodiment of the present application, and as shown in fig. 15, the communication device 150 includes a processing unit 1501 and a transceiver unit 1502.
