[0046] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0047] 1. Radio Resource Control (RRC) Connected DRX

[0048] The basic mechanism of DRX is to configure a DRX cycle for the UE in the RRC_CONNECTED state. The DRX cycle consists of "On Duration" and "Opportunity for DRX": During the "On Duration", the UE monitors and receives the Physical Downlink Control Channel (PDCCH) and so on; during the "Opportunity for DRX", the UE does not monitor the PDCCH to save power consumption. Among them, the On Duration time belongs to the active time, and the Opportunity for DRX time does not belong to the active time, that is, outside the active time, or the inactive time period. In addition, the network side device configures an inactivity timer. If a new PDCCH is received within the onduration, the inactivity timer will be started or restarted to extend the time the UE monitors the PDCCH.

[0049] DRX configuration can bring energy-saving gains, but it also increases the packet transmission delay.

[0050] 2. DRX timer and cycle configuration parameters.

[0051] The DRX timer includes a DRX duration timer (drx-onDurationTimer) and a DRX inactivity timer (drx-InactivityTimer); the cycle configuration parameters include a DRX long cycle start offset (drx-LongCycleStartOffset).

[0052] Optionally, when the DRX function is configured, the drx-onDurationTimer indicates the duration that the corresponding Medium Access Control (MAC) monitors the PDCCH in a DRX cycle, and the drx-onDurationTime is only started once in each DRX cycle.

[0053] The above-mentioned drx-InactivityTimer indicates the length of time the corresponding MAC needs to monitor the PDCCH after receiving a PDCCH indicating a new transmission. The drx-InactivityTimer starts or restarts at the first symbol after the reception of the PDCCH indicating the new transmission is completed. When the corresponding MAC receives a DRX command (Command) or a MAC control element (Long DRXcommand MAC CE) of a long DRX command, the drx-InactivityTimer is stopped. When the drx-InactivityTimer times out, if the corresponding MAC is configured for a short DRX cycle, it enters a short DRX cycle; otherwise, it enters a long DRX cycle.

[0054] The above cycle configuration parameters include two parts: the first part is the Long DRX cycle size, and the second part is the DRX start offset (drx-StartOffset), which is used to define the subframes where long cycle DRX and short cycle DRX start. Currently, the drx-startoffset of long and short cycles must be the same.

[0055] 3. PDCCH monitoring skipping solution.

[0056] 1. PDCCH skipping is a method of achieving energy savings by dynamically instructing the UE to skip PDCCH monitoring for a certain period of time through downlink control information (DCI). For example, the PDCCH skipping DCI can be used to indicate that PDCCH monitoring should be skipped for the next 4, 8, or 16 time slots. Skipping monitoring means not monitoring. Since the UE has been instructed to skip monitoring, it can enter the corresponding sleep state during this period.

[0057] 2. Search space group switching, for example, switching between search space group 0 and search space group 1, where one search space group is characterized by a sparser PDCCH monitoring period and the other search space group is characterized by a denser PDCCH monitoring period.

[0058] For example, search space group 0 is a search space associated with a sparse PDCCH monitoring period. Switching to search space group 0 can reduce PDCCH monitoring and save energy, but the scheduling delay increases.

[0059] Search space group 1: Search space associated with dense PDCCH monitoring period. Switching to search space group 1 can reduce scheduling delay, but consumes more power.

[0060] The monitoring control method provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0061] See Figure 2 , Figure 2 This is a flow chart of a monitoring control method provided by an embodiment of the present application. Figure 2 As shown, the following steps are included:

[0062] Step 201: The terminal receives a discontinuous reception (DRX) start offset adjustment indication, where the DRX start offset adjustment indication is used to indicate a start subframe of a next DRX cycle duration.

[0063] Step 202: The terminal performs a first operation according to the DRX start offset adjustment instruction;

[0064] The first operation includes at least one of the following:

[0065] Skip monitoring of the target physical downlink control channel PDCCH;

[0066] Switch to a first search space group, where 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.

[0067] In the embodiment of the present application, the above-mentioned next DRX cycle can be understood as the next DRX cycle after the current DRX cycle. The above-mentioned current DRX cycle can be understood as the DRX cycle where the DRX start offset adjustment indication is received. In other embodiments, the current DRX cycle can also be other time nodes. For example, it can be the DRX cycle where the HARQ feedback of the DCI carrying the DRX start offset adjustment indication is located, it can also be the DRX cycle where the HARQ feedback of the PDSCH scheduled by the DCI carrying the DRX start offset adjustment indication is located, it can also be the DRX cycle where the DRX start offset adjustment indication takes effect or starts to be applied after the effective delay or application delay, etc., which are not listed one by one here.

[0068] Optionally, in the XR service model, the service packet arrival intervals are equal, and the intervals are small floating-point numbers (non-positive integers) (for example, 60FPS / 16.67). In addition, the XR service has very high latency requirements, and the air interface transmission delay budget requirement (PDB) is around 10ms / 20ms. However, it is currently impossible to configure a DRX configuration that fully complies with the XR service packet arrival period. This mismatched configuration will cause very serious misalignment between the data packet and the DRX cycle. Therefore, when transmitting XR services, the starting subframe of the next DRX cycle duration can be adjusted through the above-mentioned DRX start offset adjustment indication. In this way, a DRX configuration that fully complies with the XR service packet arrival period can be configured to avoid serious misalignment between the XR service data packet and the DRX cycle, resulting in the data packet being unable to complete transmission within the PDB and being discarded. Therefore, the reliability of XR service transmission can be improved. In addition, since the first operation is triggered by the DRX start offset adjustment indication, there is no need to skip PDCCH monitoring through additional signaling, thereby reducing the system signaling overhead and data transmission delay, and improving terminal performance.

[0069] It should be understood that the DRX start offset adjustment indication is used to indicate the starting subframe of the DRX cycle duration, and can also be understood as the DRX start offset adjustment indication being used to indicate the starting time of the DRX cycle duration, where the starting time specifically refers to the starting time of the starting subframe. The starting time of the DRX cycle duration can be determined based on the starting subframe. The starting time of the DRX cycle duration can also be understood as the DRX start time.

[0070] 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 fewer PDCCH monitoring opportunities or even no PDCCH monitoring opportunities. After switching to the first search space group, since 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, terminal energy consumption is saved. Therefore, it can be understood that switching to the first search space group is also a method of skipping PDCCH monitoring.

[0071] In an embodiment of the present application, a terminal receives a discontinuous reception DRX start offset adjustment indication, and the DRX start offset adjustment indication is used to indicate the starting subframe of the next DRX cycle duration; the terminal performs a first operation according to the DRX start offset adjustment indication; wherein the first operation includes at least one of the following: skipping the target physical downlink control channel PDCCH monitoring, and switching 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. In this way, the execution of the first operation is triggered by the DRX start offset adjustment indication, thereby eliminating the need to skip PDCCH monitoring through independent signaling instructions. Therefore, the embodiment of the present application reduces service transmission delay and system signaling overhead while ensuring terminal energy saving.

[0072] Optionally, in some embodiments, the target PDCCH includes at least one of the following:

[0073] A PDCCH carrying a preset type of search space;

[0074] PDCCH carrying preset downlink control information DCI format;

[0075] PDCCH associated with a preset control resource set (CORESET);

[0076] A PDCCH carrying DCI scrambled by a preset Radio Network Temporary Identifier (RNTI).

[0077] For example, the target PDCCH may include a PDCCH carrying a Type 3 common search space (CSS) and a PDCCH carrying a user-specific search space (USS). In addition, for another example, the target PDCCH does not include a PDCCH carrying a PS-RNTI-scrambled DCI, meaning that monitoring of the DCI cannot be skipped.

[0078] Optionally, in some embodiments, the first search space group includes any one of the following:

[0079] a sleep search space group, wherein during activation of the sleep search space group, the terminal skips monitoring of the target PDCCH;

[0080] Default search space group.

[0081] In one embodiment, the sleep search space group is not associated with any search space, or the sleep search space group is not associated with a preset type search space;

[0082] The preset type search space includes at least one of the following: a type 3 public search space, a user-specific search space, and other public search spaces except the type 3 public search space.

[0083] It should be understood that the activation period of the sleep search space group can be understood as the use period of the sleep search space group. In addition, by switching to the sleep search space group, it is possible to skip monitoring of the target PDCCH, that is, not monitor the target PDCCH, to achieve energy saving.

[0084] The above-mentioned default search space group can be understood as any search space group in the search space groups agreed by the protocol or configured by the network side device. For example, the default search space group configured by the network side is search space group 0 or search space group 1.

[0085] In the embodiment of the present application, switching to the first search space group can be understood as switching from search space group 1 to search space group 0, a sleep search space group, or another defined search space group, or can also be understood as switching from search space group 0 to a sleep search space group or another defined search space group. Search space group 0: Search space associated with a sparse PDCCH listening period; search space group 1: Search space associated with a dense PDCCH listening period. No further limitations are given herein.

[0086] It should be noted that the start time for executing the first operation can be set according to actual conditions. For example, in some embodiments, the start time for executing the first operation is any one of the following:

[0087] The effective time of the DRX start offset adjustment indication;

[0088] A first moment, where the first moment is after a hybrid automatic repeat request HARQ feedback of a first DCI is completed, and the first DCI carries the DRX start offset adjustment indication;

[0089] A second time, where the second time is after HARQ feedback of the physical downlink shared channel PDSCH scheduled by the first DCI is completed;

[0090] a third moment, the third moment being after the moment when the DRX start offset adjustment indication is received, and having a first preset time interval between the third moment and the end moment of the last time unit in which the DRX start offset adjustment indication is received;

[0091] a fourth moment, the fourth moment being located after the effective moment of the DRX start offset adjustment indication, and having a second preset time interval therebetween;

[0092] The fifth moment is located after the DRX start offset adjustment indication is received.

[0093] In an embodiment of the present application, when the start time of executing the first operation is the first time, the terminal executing the first operation according to the DRX start offset adjustment indication can be understood as: executing the first operation after completing the HARQ feedback of the DCI where the DRX start offset adjustment indication is located.

[0094] When the start time of executing the first operation is the second time, the terminal executing the first operation according to the DRX start offset adjustment indication can be understood as: executing the first operation after completing the HARQ feedback of the PDSCH scheduled by the DCI where the DRX start offset adjustment indication is located.

[0095] When the start time of executing the first operation is the third time, the terminal executing the first operation according to the DRX start offset adjustment indication can be understood as: executing the first operation at the end time of the first preset time interval after receiving the DRX start offset adjustment indication.

[0096] When the start time of executing the first operation is the fourth time, the terminal executing the first operation according to the DRX start offset adjustment indication can be understood as: executing the first operation at the end time of the second preset time interval after the DRX start offset adjustment indication takes effect.

[0097] When the start time of executing the first operation is the fifth time, the terminal executing the first operation according to the DRX start offset adjustment indication can be understood as: executing the first operation after completing the reception of the DRX start offset indication.

[0098] In an embodiment of the present application, the above-mentioned first DCI can be DCI 1-1, that is, the network side device can send a DRX start offset adjustment indication through DCI 1-1, or the network side device can indicate the DRX start offset adjustment through DCI 1-1.

[0099] Optionally, in some embodiments, after the terminal performs the first operation according to the DRX start offset adjustment indication, the method further includes:

[0100] At the target time, the terminal performs a second operation; wherein the second operation includes at least one of the following: resuming monitoring of the target PDCCH; switching to a second search space group;

[0101] The second search space group includes any one of the following:

[0102] Default search space group;

[0103] A target search space group, wherein a PDCCH monitoring period corresponding to the target search space group is denser than a PDCCH monitoring period corresponding to a currently used search space group.

[0104] In some embodiments, the default search space group included in the second search space group may be the same as or different from the default search space group included in the first search space group. For example, when the two default search space groups are different, the default search space group included in the second search space group is a search space group for resuming PDCCH monitoring; the default search space group included in the first search space group can be understood as a search space group for skipping PDCCH monitoring. The second operation corresponds to the first operation. For example, assuming that 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 target PDCCH monitoring, the second operation includes resuming the target PDCCH monitoring.

[0105] 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 no further limitation is given herein.

[0106] Optionally, the target moment is a preset moment, or before the preset moment, or after the preset moment; wherein the preset moment is the starting moment of the starting subframe of the next DRX cycle duration.

[0107] In the embodiment of the present application, the time at which the terminal performs the second operation before the preset time can be understood as: performing the second operation at any time before the start time of the starting subframe of the next DRX cycle duration. In some embodiments, when the target time is before the preset time, the second operation satisfies at least one of the following:

[0108] At the preset time or before the preset time, completing the second operation;

[0109] The second operation is performed at a seventh moment, the seventh moment is before the preset moment, and there is a third preset time interval between the seventh moment and the preset moment.

[0110] In an embodiment of the present application, the length of the third preset time interval can 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 delay, so as to ensure that the second operation is completed at the preset time or before the preset time.

[0111] Optionally, the moment when the terminal performs the second operation is the preset moment, which can be understood as starting to perform the second operation at the start moment of the starting subframe of the next DRX cycle duration. The moment when the terminal performs the second operation is after the preset moment, which can be understood as performing the second operation at any moment after the start moment of the starting subframe of the next DRX cycle duration.

[0112] Optionally, in some embodiments, the step of the terminal performing the first operation according to the DRX start offset adjustment indication includes:

[0113] The terminal performs a first operation when receiving the DRX start offset adjustment instruction and a preset condition is met;

[0114] The preset conditions include at least one of the following:

[0115] The network side device configuration or protocol stipulates that the DRX start offset adjustment indication has the function of triggering the execution of the first operation;

[0116] The DRX start offset adjustment indication carries target indication information, and the target indication information indicates that the DRX start offset adjustment indication has a function of triggering execution of the first operation.

[0117] In an embodiment of the present application, the network side device can configure or agree whether the DRX start offset adjustment indication has the function of implicitly triggering the first operation. When it has the function of implicitly triggering the first operation, the terminal can trigger the terminal to perform the first operation after receiving the DRX start offset adjustment indication.

[0118] It should be understood that the network-side device can carry target indication information in the DRX start offset adjustment indication, so that the DRX start offset adjustment indication has the function of triggering the execution of the first operation. At this time, the target indication information can be understood as an identification information, or can be understood as an indication of whether the first operation is effective. When the identification information is a first value (for example, 1), it indicates that the DRX start offset adjustment indication has the function of triggering the execution of the first operation. When the identification information is a second value (for example, 0), it indicates that the DRX start offset adjustment indication does not have the function of triggering the execution of the first operation. In this case, when the DRX start offset adjustment indication is received, the first operation will not be performed.

[0119] Optionally, in some embodiments, the DRX start offset adjustment indication is carried in a first DCI, and when the first DCI is a DCI that does not schedule data, the method further includes:

[0120] After detecting the first DCI, the terminal sends a positive acknowledgement ACK of the first DCI.

[0121] In an embodiment of the present application, if the first DCI does not schedule data, if the terminal detects the first DCI, it is necessary to send an ACK for the first DCI. In this case, the definition of the effective time of the DRX start offset adjustment indication can be set according to actual needs. For example, in some embodiments, the effective time of the DRX start offset adjustment indication is any one of the following:

[0122] The end time of the last time unit at which the first DCI is received;

[0123] the end time of the last time unit for sending the ACK of the first DCI;

[0124] An eighth moment, where the eighth moment is located after the last time unit for receiving the first DCI, and a fourth preset time interval exists between the eighth moment and the last time unit for receiving the first DCI.

[0125] In the embodiment of the present application, the above-mentioned time unit may be a time slot or a symbol, and the symbol may be understood as an orthogonal frequency division multiplex (OFDM) symbol.

[0126] 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 to indicate the starting subframe of the next DRX cycle duration, and the second indication information is used to indicate the time offset of the starting moment of the next DRX cycle duration relative to the starting moment of the starting subframe of the current DRX cycle duration.

[0127] In this embodiment of the present application, the first indication information can be understood as indicating or representing the value of drx-startoffset, i.e., an absolute value. The second indication information can be understood as a relative value, i.e., Δ, which can represent a change relative to the currently effective drx-startoffset. For example, if the current drx-startoffset is subframe 4, Δ=+2 indicates that the adjusted drx-startoffset is subframe 6.

[0128] It should be noted that, in some embodiments, if the DRX start offset adjustment indication includes second indication information, a group of candidate values ​​can be first configured by high-level signaling, and then the DRX start offset adjustment indication can be used to indicate one of the candidate values, and the number of indication field bits is determined based on the number of candidate values.

[0129] In order to better understand the present application, some specific examples are provided below for illustration.

[0130] Embodiment 1: The PDCCH monitoring skipping function is implicitly implemented by receiving a DRX start offset adjustment indication. The PDCCH monitoring skipping effect is achieved by PDCCH skipping.

[0131] Optionally, the network side device is configured to carry the DRX start offset adjustment indication through DCI 1-1.

[0132] The network side device is configured to skip subsequent PDCCH monitoring upon receiving a DRX start offset adjustment indication, wherein the DRX start time of the next DRX cycle is indicated, wherein the DRX cycle where the slot of DCI 1-1 is located is used as the current DRX cycle.

[0133] In addition, PDCCH monitoring is resumed at the adjusted DRX start time determined according to the received DRX start offset adjustment indication.

[0134] like Figure 3 As shown in FIG, at time 1 of DRX cycle 1, a DCI indicating that the DRX start offset is adjusted to 4 slots is received. After receiving the DCI, the first operation will be performed, that is, PDCCH monitoring will be skipped. At the start time of DRX cycle 2, the second operation will be performed, that is, PDCCH monitoring will be resumed. The duration of skipping PDCCH monitoring is as follows: Figure 3 As shown, the duration of skipping PDCCH monitoring may start at a certain time after time 1 and end at the start time of DRX cycle 2 (ie, time 2).

[0135] This embodiment implicitly indicates to skip PDCCH monitoring, which not only saves signaling overhead, but also reduces the application delay of independent signaling, while saving time and ensuring terminal transmission performance. It is suitable for XR non-positive integer quasi-periodic service characteristics.

[0136] Embodiment 2: The PDCCH monitoring skipping function is implicitly implemented by receiving a DRX start offset adjustment indication. The PDCCH monitoring skipping effect is achieved by switching to a sleep search space group.

[0137] Optionally, the network side device is configured to carry the DRX start offset adjustment indication through DCI 1-1.

[0138] The network side device is configured to switch to the sleep search space group upon receiving the DRX start offset adjustment indication. The terminal does not need to monitor the PDCCH carrying Type 3 CSS and USS when applying the sleep search space group. The DRX start offset adjustment indication is used to indicate the DRX start time of the next DRX cycle.

[0139] Furthermore, at a predetermined time before the adjusted DRX start time determined according to the received DRX start offset adjustment indication, switching back to the default search space group is performed. The predetermined time and the adjusted DRX start time are separated by a search space group switching delay. The default search space group is configured by the network-side device.

[0140] like Figure 4 As shown in FIG, at time 3 of DRX cycle 1, a DCI indicating that the DRX start offset is adjusted to 4 slots is received. After receiving the DCI, the first operation is performed, i.e., switching to the sleep search space group. At the start time of DRX cycle 2 (i.e., time 4), the second operation is performed, i.e., switching to the default search space group. The activation / use duration of the default search space group is as follows: Figure 4 As shown, the activation / use duration of the default search space group may be from a certain moment after moment 3 to a certain moment before the start moment of DRX cycle 2 (such as moment 5), and the time from moment 5 to the start moment of DRX cycle 2 is greater than or equal to the switching delay of the search space group.

[0141] Embodiment 3: receiving indication information, where the indication information includes: a DRX start offset adjustment indication and an indication of whether the first operation is effective.

[0142] If the first action in the indication information indicates "valid", the network device will skip PDCCH monitoring or switch to the sleep search space group upon receiving the DRX start offset adjustment indication. If the first action in the indication information indicates "invalid", the network device will not skip PDCCH monitoring or switch to the sleep search space group upon receiving the DRX start offset adjustment indication. In this case, only adjusting the DRX start offset does not trigger the PDCCH monitoring skipping function.

[0143] Optionally, the above indication information may be carried by DCI, and the content of the DRX start offset adjustment indication is the absolute value of the DRX start offset. Whether the first operation is effective may be indicated by 1 bit, for example, "0" indicates ineffective and "1" indicates effective.
