For convenience of understanding, some contents related to the embodiments of the present application are described below:

first, Radio Resource Control (RRC) CONNECTED (CONNECTED) state DRX.

The basic mechanism of DRX is to configure one DRX cycle for a UE in RRC _ CONNECTED state. The DRX cycle consists of "Duration (On Duration)" and "Opportunity for DRX" (DRX): in the "On Duration" time, the UE monitors and receives a Physical Downlink Control Channel (PDCCH) and the like; during the "Opportunity for DRX" time, the UE does not monitor the PDCCH to save power consumption. The time of the On Duration belongs to an active time (active time), and the Opportunity for DRX time does not belong to an active time, i.e., an active time (out active time), or an inactive time period. In addition, the network side device configures an activity timer (inactivity timer), and if a newly transmitted PDCCH is received in the duration, the inactivity timer is started or restarted to extend the time duration for the UE to monitor the PDCCH.

The DRX configuration can bring about power saving gain, but also brings about an increase in packet transmission delay.

And II, a DRX timer (timer) and a cycle configuration parameter.

The DRX timer includes a DRX duration timer (DRX-onDurationTimer) and a DRX inactivity timer (DRX-inactivity timer); the cycle configuration parameters include a DRX long cycle start offset (DRX-LongCycleStartOffset).

Optionally, when the DRX function is configured, the DRX-onDurationTimer indicates a duration for a corresponding Medium Access Control (MAC) to monitor the PDCCH in one DRX cycle. And the DRX-onDurationTime is started only once per DRX cycle.

The drx-inactivity timer indicates a duration that the corresponding MAC needs to monitor the PDCCH after receiving a PDCCH indicating a new transmission. The drx-inactivity timer is started or restarted at the first symbol after indicating the end of receiving the newly transmitted PDCCH. When the corresponding MAC receives a DRX Command (Command) or a MAC control element (Long DRX Command MAC CE) of the Long DRX Command, the DRX-inactivity timer is stopped. And when the DRX-InactivetyTimer is over, entering a short DRX period if the short DRX period is configured corresponding to the MAC, or entering a long DRX period if the short DRX period is not configured corresponding to the MAC.

The cycle configuration parameters include two parts, the first part is Long DRX cycle size, and the second part is DRX start offset (DRX-StartOffset) used to define the subframes where Long cycle DRX and short cycle DRX start; the current drx-startoffset for long and short periods must be the same.

And thirdly, a PDCCH monitoring skipping (skiping) scheme.

1. PDCCH blanking is a method for saving energy by dynamically indicating to skip PDCCH monitoring for a period of time interval through Downlink Control Information (DCI). Skipping PDCCH monitoring in the next 4, 8 or 16 slots (slots) is indicated, for example, by PDCCH blanking DCI. Skipping snoops means not snooping. Now that the UE has been instructed to skip listening, the UE may enter a corresponding sleep state during this time.

2. Search space group switching, for example, between search space group 0 and search space group 1, where one search space group is characterized by a more sparse (sparse) PDCCH monitoring (monitoring) period and the other search space group is characterized by a more dense (dense) PDCCH monitoring (monitoring) period.

For example, search space group 0: switching to search space group 0 in association with the search space of the sparse PDCCH monitoring period can achieve reduction of PDCCH monitoring, saving energy but increasing scheduling delay.

Search space group 1: switching to search space group 1 in association with the search space of the dense PDCCH monitoring period may achieve reduction of scheduling delay, but power consumption is large.

The following describes the monitoring control method provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a monitoring control method according to an embodiment of the present application, and as shown in fig. 2, the method includes the following steps:

step 201, a terminal receives a Discontinuous Reception (DRX) initial offset adjustment instruction, wherein the DRX initial offset adjustment instruction is used for indicating an initial subframe of the duration of the next DRX period;

step 202, the terminal executes a first operation according to the DRX initial offset adjustment instruction;

wherein the first operation comprises at least one of:

skipping target physical downlink control channel PDCCH monitoring;

In this embodiment, the next DRX cycle may be understood as a next DRX cycle after the current DRX cycle. The current DRX cycle described above may be understood as the DRX cycle at which the DRX start offset adjustment indication is received. In other embodiments, the current DRX cycle may also be other time nodes. For example, the DRX cycle in which the HARQ feedback of the DCI carrying the DRX initial offset adjustment instruction is located may be used, the DRX cycle in which the HARQ feedback of the PDSCH scheduled by the DCI carrying the DRX initial offset adjustment instruction is located may be used, the DRX initial offset adjustment instruction may be used to start to be effective after an effective delay or an application delay, or the DRX initial offset adjustment instruction may be used to start to be effective or start to apply a time.

Alternatively, in the XR traffic model, traffic packet arrivals are equally spaced, and the spacing is a small floating-point number (non-positive integer) (e.g., 60 FPS/16.67). In addition, the XR service has a high delay requirement, the air interface transmission delay budget requirement (PDB) is about 10ms/20ms, and currently, a DRX configuration completely conforming to the arrival period of the XR service packet cannot be configured, and such unmatched configuration may cause very serious misalignment between the data packet and the DRX cycle. Therefore, when XR traffic transmission is performed, the starting subframe of the next DRX cycle duration can be adjusted by the DRX starting offset adjustment instruction. Therefore, the DRX configuration of the data packet arrival cycle completely conforming to the XR service can be configured, and the data packet of the XR service is prevented from being seriously staggered with the DRX cycle, so that the data packet cannot be transmitted in the PDB and is discarded. The reliability of XR traffic transmission can be improved. In addition, the first operation is triggered and executed through the DRX initial offset adjustment indication, so that the PDCCH monitoring is not required to be skipped through extra signaling indication, the signaling overhead and the data transmission delay of the system are reduced, and the performance of the terminal is improved.

It should be understood that the above DRX initial offset adjustment indication is used for indicating the initial subframe of the DRX cycle duration, and may also be understood as the DRX initial offset adjustment indication is used for indicating the initial time of the DRX cycle duration, which is specifically the initial time of the initial subframe. The starting moment of the DRX cycle duration can be determined from the starting subframe. Wherein, the starting time of the DRX cycle duration can also be understood as the DRX starting time.

It should be noted that the PDCCH monitoring period corresponding to the first search space group is sparser than the PDCCH monitoring period corresponding to the currently used search space group, which can be understood as that there are fewer PDCCH monitoring opportunities, or even no PDCCH monitoring opportunities. After the search space group is switched to the first search space group, the PDCCH monitoring period corresponding to the first search space group is sparser than the PDCCH monitoring period corresponding to the currently used search space group, so that the energy consumption of the terminal is saved. Therefore, it can be understood that switching to the first search space group is also a method of skipping PDCCH monitoring.

Optionally, in some embodiments, the target PDCCH includes at least one of:

a PDCCH bearing a preset type search space;

a PDCCH bearing a preset DCI format;

a PDCCH associated to a preset control resource set (CORESET);

a PDCCH carrying DCI scrambled by a preset Radio Network Temporary Identifier (RNTI).

For example, the target PDCCH may include a PDCCH carrying a Common Search Space (CSS) of Type 3(Type 3) and a PDCCH carrying a user specific Search Space (USS). In addition, for another example, the target PDCCH does not include a PDCCH of the PS-RNTI scrambled DCI, that is, monitoring of the DCI cannot be skipped.

Optionally, in some embodiments, the first search space group comprises any one of:

a dormant search space group, during the activation of the dormant search space group, the terminal skips the target PDCCH monitoring;

a default set of search spaces.

In one embodiment, the dormant search space group is not associated with any search space, or the dormant search space group is not associated with a preset type search space;

wherein the preset type search space comprises at least one of: a type3 common search space, a user-specific search space, and other common search spaces other than the type3 common search space.

It should be understood that the activation period of the dormant search space group described above may be understood as a usage period of the dormant search space group. In addition, the switching to the dormant search space group may implement skipping of monitoring of the target PDCCH, i.e., not performing monitoring of the target PDCCH, to implement energy saving.

The default search space group may be understood as any one of search space groups agreed by a protocol or configured by a network side device, for example, the network side configures the default search space group as search space group 0 or search space group 1.

In the embodiment of the present application, switching to the first search space group may be understood as switching from the search space group 1 to the search space group 0, the dormant search space group, or another defined search space group, or switching from the search space group 0 to the dormant search space group or another defined search space group. Wherein search space group 0: associating a search space of a sparse PDCCH monitoring period; search space group 1: a search space associated with the dense PDCCH listening period. And are not further limited herein.

It should be noted that, the starting time for executing the first operation may be set according to actual situations, for example, in some embodiments, the starting time for executing the first operation is any one of the following:

the effective time of the DRX starting offset adjustment indication;

a first time, after completing hybrid automatic repeat request (HARQ) feedback of first DCI, the first DCI carries the DRX initial offset adjustment instruction;

a second time, which is located after the HARQ feedback of the PDSCH of the physical downlink shared channel scheduled by the first DCI is completed;

a third time, which is after the time when the DRX starting offset adjustment instruction is received, and has a first preset time interval with the end time of the last time unit when the DRX starting offset adjustment instruction is received;

a fourth time, which is located after the effective time of the DRX initial offset adjustment instruction, and the fourth time and the effective time of the DRX initial offset adjustment instruction have a second preset time interval;

a fifth time after completing reception of the DRX start offset adjustment indication.

In this embodiment of the application, when the starting time of executing the first operation is a first time, the terminal executing the first operation according to the DRX initial offset adjustment instruction may be understood as: after completing the HARQ feedback of the DCI where the DRX start offset adjustment is indicated, a first operation is performed.

When the starting time of executing the first operation is the second time, the terminal executing the first operation according to the DRX starting offset adjustment instruction may be understood as: and after finishing the HARQ feedback of the PDSCH scheduled by the DCI where the DRX initial offset adjustment instruction is located, executing a first operation.

When the starting time of executing the first operation is the third time, the terminal executing the first operation according to the DRX starting offset adjustment instruction may be understood as: and executing a first operation at the end time of a first preset time interval after receiving the DRX initial offset adjustment instruction.

When the starting time of executing the first operation is the fourth time, the terminal executing the first operation according to the DRX starting offset adjustment instruction may be understood as: and executing the first operation at the end time of the second preset time interval after the DRX initial offset adjustment instruction takes effect.

When the starting time of performing the first operation is the fifth time, performing the first operation according to the DRX starting offset adjustment instruction by the terminal may be understood as: after the DRX start offset indication reception is completed, a first operation is performed.

In this embodiment of the application, the first DCI may be DCI 1-1, that is, the network side device may send the DRX initial offset adjustment instruction through DCI 1-1, or the network side device may indicate the DRX initial offset adjustment through DCI 1-1.

Optionally, in some embodiments, after the terminal performs the step of the first operation according to the DRX start offset adjustment indication, the method further includes:

at the target moment, the terminal executes a second operation; wherein the second operation comprises at least one of: resuming the target PDCCH monitoring; switching to a second search space group;

wherein the second search space group comprises any one of:

a default set of search spaces;

and the PDCCH monitoring period corresponding to the target search space group is denser than the PDCCH monitoring period corresponding to the currently used search space group.

In some embodiments, the second search space group may comprise the same or different default search space group than the first search space group. For example, when two default search space groups are different, the second search space group includes a default search space group that is a search space group for resuming PDCCH monitoring; the first search space group may include a default search space group that may be understood as a search space group for skipping PDCCH monitoring. The second operation corresponds to the first operation, for example, if the first operation includes switching to the first search space group, the second operation includes switching to the second search space group. Assuming that the first operation includes skipping the targeted PDCCH monitoring, the second operation includes resuming the targeted PDCCH monitoring.

It should be understood that the default search space group and the target search space group included in the second search space group may be search space group 0, search space group 1, or other defined search space groups, and are not further limited herein.

Optionally, the target time is a preset time, or is before the preset time, or is after the preset time; and the preset moment is the starting moment of the starting subframe of the duration of the next DRX cycle.

In this embodiment of the application, the time when the terminal executes the second operation before the preset time may be understood as: performing a second operation at any time before a start time of a start subframe of the next DRX cycle duration. In some embodiments, in a case where the target time is before the preset time, the second operation satisfies at least one of:

completing the second operation at the preset time or before the preset time;

and starting to execute the second operation at a seventh moment, wherein the seventh moment is before the preset moment, and a third preset time interval is formed between the seventh moment and the preset moment.

In this embodiment of the application, the time length of the third preset time interval may be set according to actual needs, for example, in some embodiments, the third preset time interval is greater than or equal to the search space group switching time delay, so that it is ensured that the second operation is completed at the preset time or before the preset time.

Optionally, the time when the terminal performs the second operation is the preset time, which may be understood as starting to perform the second operation at the starting time of the starting subframe of the next DRX cycle duration. The time when the terminal performs the second operation is after the preset time, which may be understood as performing the second operation at any time after the starting time of the starting subframe of the next DRX cycle duration.

Optionally, in some embodiments, the terminal performs a first operation according to the DRX start offset adjustment indication, including:

the terminal executes a first operation when receiving the DRX initial offset adjustment instruction and meeting a preset condition;

the preset condition comprises at least one of the following conditions:

the network side equipment configuration or protocol appoints the DRX initial offset adjustment indication to have a function of triggering the execution of the first operation;

the DRX initial offset adjustment instruction carries target indication information, and the target indication information indicates that the DRX initial offset adjustment instruction has a function of triggering execution of the first operation.

In this embodiment of the present application, a network side device may configure or agree whether the DRX initial offset adjustment instruction has a function of implicitly triggering a first operation, and when the DRX initial offset adjustment instruction has the function of implicitly triggering the first operation, a terminal may trigger the terminal to execute the first operation after receiving the DRX initial offset adjustment instruction.

It should be understood that the network side device may have a function of triggering execution of the first operation by carrying target indication information in the DRX initial offset adjustment indication. The target indication information may be understood as an identification information at this time, or may be understood as an indication whether the first operation is effective or not. When the identification information is a first value (e.g., 1), it indicates that the DRX start offset adjustment indication has a function of triggering execution of the first operation, and when the identification information is a second value (e.g., 0), it indicates that the DRX start offset adjustment indication does not have a function of triggering execution of the first operation, and at this time, in case of receiving the DRX start offset adjustment indication, the first operation will not be executed.

Optionally, in some embodiments, the DRX starting offset adjustment indication is carried in a first DCI, and in a case that the first DCI is a DCI without scheduling data, the method further includes:

and the terminal sends a positive acknowledgement ACK of the first DCI after detecting the first DCI.

In this embodiment of the present application, in a case that the first DCI does not schedule data, if the terminal detects the first DCI, an ACK of the first DCI needs to be sent. At this time, the definition of the effective time of the DRX start offset adjustment indication may be set according to actual needs, for example, in some embodiments, the effective time of the DRX start offset adjustment indication is any of the following:

receiving a last time unit end time of the first DCI;

an end time of a last time unit of the ACK of the first DCI is sent;

and an eighth time, which is located after the last time unit for receiving the first DCI, and has a fourth preset time interval with the last time unit for receiving the first DCI.

In the embodiment of the present application, the time unit may be a time slot or a symbol, and the symbol may be understood as an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

Optionally, in some embodiments, the content of the DRX start offset adjustment indication includes first indication information or second indication information, the first indication information is used for indicating a start subframe of the next DRX cycle duration, and the second indication information is used for indicating a time offset of a start time of the next DRX cycle duration relative to a start time of the start subframe of the current DRX cycle duration.

In the embodiment of the present application, the first indication information may be understood as a value, i.e., an absolute value, for indicating or determining drx-startoffset, and the second indication information may be understood as a relative value, i.e., Δ, which may indicate a change value from drx-startoffset currently in effect. For example, the current drx-startoffset is subframe (subframe)4, Δ ═ 2, which indicates that the adjusted drx-startoffset is subframe 6.

It should be noted that, in some embodiments, if the DRX initial offset adjustment indication includes the second indication information, a set of candidate values may be configured by a higher layer signaling first, and then one of the candidate values is indicated by the DRX initial offset adjustment indication, where the number of bits in the indication field is determined based on the number of the candidate values.

For a better understanding of the present application, the following description is given by way of some specific examples.

Example 1: the PDCCH monitoring skip function is implicitly implemented by receiving a DRX start offset adjustment indication, which PDCCH monitoring skip effect is achieved by PDCCH skiping.

Optionally, the network side device configuration carries the DRX starting offset adjustment indication through DCI 1-1.

The network side equipment configuration receives a DRX initial offset adjustment instruction, and skips the subsequent PDCCH monitoring; the DRX start offset adjustment indication indicates a DRX start time for a next DRX cycle (cycle). And the DRX cycle in which the Slot in which the DCI 1-1 is located is used as the current DRX cycle.

Furthermore, the PDCCH monitoring is resumed at the adjusted DRX start time determined from the received DRX start offset adjustment indication.

As shown in fig. 3, receiving DCI at time 1 of DRX cycle 1 indicates that the DRX start offset is adjusted to 4 slots, and the first operation, namely skipping PDCCH monitoring, is performed after receiving DCI. At the starting time of DRX cycle2, the second operation, i.e., resuming PDCCH monitoring, is performed. The duration in which PDCCH monitoring is skipped may start at a time after time 1 and be the duration of skipping PDCCH monitoring to the starting time of DRX cycle2 (i.e., time 2), as shown in fig. 3.

In this embodiment, the PDCCH monitoring is skipped by implicit indication, which not only saves signaling overhead, but also reduces the respective application delay of independent signaling, and simultaneously saves time and ensures terminal transmission performance, and is suitable for XR non-positive integer quasi-periodic service features.

Example two: the PDCCH monitoring skip function is implicitly implemented by receiving a DRX start offset adjustment indication, which is achieved by switching to a dormant search space group.

And if the network side equipment configuration receives the DRX initial offset adjustment instruction, switching to the dormant search space group, and when the terminal applies the dormant search space group, not needing to monitor the PDCCH bearing the Type3 CSS and the USS. The DRX start offset adjustment indication is used for indicating the DRX start time of the next DRX cycle.

Further, a switch back to the default search space group is performed at a predetermined time prior to the adjusted DRX start time determined from the received DRX start offset adjustment indication. The distance between the preset time and the adjusted DRX starting time is equal to the switching time delay of the search space group; wherein the default search space group is configured by the network side device.

As shown in fig. 4, receiving DCI at time 3 of DRX cycle 1 indicates that the DRX start offset is adjusted to 4 slots, and a first operation, i.e., switching to the dormant search space group, is performed after receiving the DCI. At the starting time of DRX cycle2 (i.e., time 4), the second operation, i.e., switching to the default search space group, is performed.
