[0056] 1) DRX

[0057] Please refer to Figure 2, which shows a schematic diagram of a DRX cycle involved in this application. As shown in Figure 2, the DRX mechanism in the Radio Resource Control (RRC)-Connected state is to configure a DRX cycle for the UE. The DRX cycle consists of the initial DRX on duration (on duration, which can be understood as the activation period, the terminal needs to monitor the PDCCH), and the potential dormant period (also known as the DRX opportunity (Opportunity for DRX)). During the potential dormant period, the UE may not monitor the PDCCH to reduce power consumption. RRC controls the DRX operation of the terminal by configuring the following parameters (some parameters related to this application are listed below):

[0058] -drx-onDurationTimer (DRX activation time timer): the duration at the beginning of a DRX cycle; (the activation time from the start of the DRX cycle, that is, the time for continuous monitoring of PDCCH);

[0059] -drx-SlotOffset (DRX slot offset): the delay before starting the drx-onDurationTimer; (the delay before starting the DRX activation time timer is the slot-level offset of the DRX on duration);

[0060] -drx-InactivityTimer (DRX-Inactivity Timer): the duration after the PDCCH occasion in which a PDCCH indicates a new UL or DL ​​transmission for the MAC entity; (i.e., the duration of the DRX inactivity timer after the UE successfully decodes a PDCCH indicating a new UL / DL transmission);

[0061] -drx-LongCycleStartOffset (DRX long cycle start offset): the Long DRX cycle and drx-StartOffset which defines the subframe where the Long and Short DRX cycle starts; (Long DRX cycle and DRX start offset, define the starting subframe of the long and short DRX cycle; that is, the DRX cycle period and the offset of the starting subframe);

[0062] That is, the terminal starts drx-onDurationTimer after drx-SlotOffset timeslots in a subframe that meets the following condition: [(SFN × 10) + subframe number] modulo (drx-LongCycle) = drx-StartOffset. SFN is the system frame number, subframe number is the subframe number, modulo is the modulo sign, and drx-LongCycle is the long DRX cycle.

[0063] The optional values ​​of DRX period include: {2ms, 3ms, 4ms, 5ms, 6ms...}, {10ms, 20ms, 32ms, 40ms, 60ms, 64ms...}.

[0064] 2) Rel-18 XR

[0065] The video service in the extended reality (XR) service has a non-integer period, for example, a service period of 1 / 60s (16.66ms) corresponding to a frame rate of 60fps, a service period of 1 / 90s (11.11ms) corresponding to a frame rate of 90fps, and a service period of 1 / 120s (8.33ms) corresponding to a frame rate of 120fps. However, according to the above introduction to DRX, the DRX period is an integer. It can be seen that the DRX period and the XR / Cloud Gaming (CG) service period do not match. Taking the mismatch between the service period and the DRX period as an example, please refer to Figure 3, which shows a schematic diagram of the period of the video service involved in this application. As shown in Figure 3, the DL video period is 16.67ms, the DRX period is 16ms, and the drx-onDurationTimer is configured to be 2ms. It can be seen that if the first transmission of the DL video is aligned with the start boundary of the drx-onDurationTimer, after 3 DRX cycles (4 DL video transmissions), the 5th DL The video falls outside the drx-onDurationTimer and needs to wait for ((16-2-0.67)ms=13.33ms) UE wake up (drx-onDurationTimer is turned on) before it can be scheduled / transmitted. However, the latency of XR / CG services is relatively urgent. If the 13.33ms wait is required, the latency requirement of XR / CG services cannot be met, affecting the user experience.

[0066] Based on this, 3GPP proposes to enhance DRX to match the non-integer service cycle characteristics of XR / CG. The enhancement is based on semi-static RRC configuration. This application proposes the following candidate DRX enhancement methods:

[0067] Method 1: RRC configures multiple cycles, which are combined into a DRX pattern. This pattern is configured in a periodic manner, for example, a periodic pattern of {16, 17, 17} ms.

[0068] As shown in FIG4 , it shows a configuration diagram of the corresponding DRX enhancement method 1 involved in this application.

[0069] Method 2: Configure multiple DRX start offsets within a DRX cycle. This allows for multiple DRX ondurations within a DRX cycle. For example, configure three start offsets within a 50ms cycle: 0ms, 16ms, and 33ms. This results in three sub-cycles within the 50ms cycle: 16ms, 17ms, and 17ms.

[0070] As shown in FIG5 , it shows a configuration diagram of the corresponding DRX enhancement method 2 involved in this application.

[0071] Method 3: Introduce a non-integer DRX cycle, such as 50 / 3ms (≈16.67ms), 100 / 3ms (≈33.33ms), or 25 / 3ms (≈8.33ms). Then modify the DRX formula as follows: the UE starts the DRX on duration timer in the subframe that satisfies the following formula:

[0072] floor{[(SFN×10)+subframe number]modulo(drx-Cycle)}=drx-StartOffset, where floor is rounded down.

[0073] Taking a non-integer DRX cycle of 50 / 3 ms as an example, as shown in FIG6 , it shows a configuration diagram of the corresponding DRX enhancement method 3 involved in this application.

[0074] Although the enhancements to the matching of the DRX cycle and the XR non-integer cycle are semi-static, meaning that most of the work is done in the Radio Access Network (RAN) 2, regardless of which of the above approaches RAN2 agrees to adopt, the position of the DRX on duration will no longer be strictly periodic like in traditional DRX, and the definition of the DRX cycle will be modified to some extent. This will affect UE behaviors related to the DRX cycle in the RAN1 protocol, for example:

[0075] 1) TS 38.213:

[0076] Radio link monitoring: In DRX mode operation, the physical layer in the UE assesses once per indication period the radio link quality, evaluated over the previous time period defined in [10, TS 38.133], against thresholds (Qout and Qin) provided by rlmInSyncOutOfSyncThreshold. The UE determines the indication period as the maximum between the shortest periodicity for radio link monitoring resources and the DRX period.

[0077] Radio Link Monitoring (RLM) is the process by which a UE in the RRC_CONNECTED state monitors the downlink radio link quality of the primary cell. After configuring the RLM-RS, the UE measures the RLM-Reference Signal (RS) and compares the measurement result with the IS / OOS (in sync / out of sync) threshold to determine the IS / OOS status of the radio link. The UE periodically reports the IS / OOS status evaluation results to higher layers.

[0078] In the non-DRX state, the reporting period of the IS / OOS status is the maximum value between the shortest period of all configured RLM-RS resource cycles and 10ms. In the DRX state, the reporting period of the IS / OOS status is the maximum value between the shortest period of all configured RLM-RS resource cycles and the DRX cycle.

[0079] Taking the XR service of 50 / 3 (~16.67) ms as an example, in the DRX state, when determining the reporting period of the IS / OOS state, it is necessary to clarify whether the "DRX cycle" used is 16ms, 17ms, 50ms, or 16.67ms.

[0080] Scell ​​PDCCH monitoring indication and sleep / non-sleep behavior:

[0081] The following information may be provided to a UE configured with DRX mode operation [11, TS 38.321] for detecting DCI format 2_6 in PDCCH reception on a PCell or SpCell [12, TS 38.131].

[0082] -ps-PositionDCI-2-6 indicates the position of the wake-up indication bit in DCI format 2_6;

[0083] - When reporting to higher layers, a value of '0' for the wake-up indication bit indicates not to start the drx onDurationTimer during the next long drx cycle [11, TS 38.321];

[0084] - when a value of '1' of the wake-up indication bit is reported to higher layers, it indicates the start of the drx onDurationTimer for the next long drx cycle [11, TS38.321];

[0085] -ps offset indicates the time, before the time slot at which drx onDurationTimer will start on the PCell or SpCell, when the UE starts monitoring the PDCCH to detect DCI format 2_6 according to the number of search space sets [11, TS 38.321];

[0086] - For each search space set, the PDCCH monitoring opportunity is the opportunity in the first T_"s" slots indicated by the duration, or if no duration is provided, then T_"s" = 1 slot, starting from the first slot of the first T_s" slots and ending before the start of drx onDurationTimer.

[0087] (PDCCH monitoring indication and dormancy / non-dormancy behavior for Scells:

[0088] A UE configured with DRX mode operation[11,TS 38.321]can be provided the following for detection of a DCI format 2_6 in a PDCCH reception on the PCell or on the SpCell[12,TS 38.331]。

[0089] -a location in DCI format 2_6 of a Wake-up indication bit by ps-PositionDCI-2-6;

[0090] -a'0'value for the Wake-up indication bit,when reported to higher layers,indicates to not start the drx-onDurationTimer for the next long DRX cycle[11,TS 38.321];

[0091] -a'1'value for the Wake-up indication bit,when reported to higher layers,indicates to start the drx-onDurationTimer for the next long DRX cycle[11,TS 38.321];

[0092] -an offset by ps-Offset indicating a time,where the UE starts monitoring PDCCH for detection of DCI format2_6according to the number of search space sets,prior to a slot where the drx-onDurationTimer would start on the PCell or on the SpCell[11,TS 38.321];

[0093] -for each search space set, the PDCCH monitoring occasions are the ones in the first T_"s"slots indicated by duration, or T_"s"=1slot if duration is not provided, starting from the first slot of the first T_"s"slots and ending prior to the start of drx-onDurationTimer. )

[0094] NR supports sending an energy-saving wake-up signal (downlink control information (DCI) format 2_6) by the network side before each DRX long cycle to inform the terminal whether there will be data arriving in the next long DRX cycle, that is, whether it needs to wake up in the next drx-onDurationTimer. Only when the received DCI format 2_6 indicates wake-up, the terminal starts the DRX-onDurationTimer and starts monitoring the PDCCH. Therefore, the terminal monitors the PDCCH carrying DCI format 2_6 in certain slots before each DRX on duration timer.

[0095] Taking the XR service of 50 / 3 (~16.67) ms as an example, after semi-static enhancement of DRX, it is necessary to clarify how the terminal determines the position of the PDCCH carrying DCI format 2_6 monitored by the terminal, and whether the on duration of which DRX cycle indicated by DCI format 2_6 needs to be woken up.

[0096] TS 38.214:

[0097] CSI-RS for mobility:

[0098] If the UE is configured with DRX and DRX cycle in use is larger than 80 msec, the UE may not expect CSI-RS resources are available other than during the active time for measurements based on CSI-RS-Resource-Mobility. If the UE is configured with DRX and configured to monitor DCI format 2_6 and DRX cycle in use is larger than 80 msec, the UE may not expect that the CSI-RS resources are available other than during the active time and for the duration indicated by DRX-onDurationTimer in DRX Config, also outside the active time for measurements based on CSI-RS-Resource-Mobility. CSI-RS resources are available other than during the active time and during the time duration indicated by drx-onDurationTimer in DRX-Config also outside active time for measurements based on CSI-RS-Resource-Mobility. Otherwise, the UE may assume CSI-RS are available for measurements based on CSI-RS-Resource-Mobility).

[0099] In order to save the power consumption of UE for measurement, NR stipulates that if the terminal is in DRX mode and the DRX cycle value is greater than 80ms, the terminal does not expect CSI-RS resources to be available except for the measurement activation time configured based on Channel State Information (CSI)-RS-Resource-Mobility, that is, the terminal can not make measurements at other times.

[0100] The threshold of the DRX cycle is specified as 80 ms. Therefore, after semi-static enhancement of DRX, it is necessary to clarify whether the DRX cycle used to determine the available time of CSI-RS is the aforementioned 16 ms, 17 ms, 50 ms, or 16.67 ms.

[0101] Please refer to FIG7 , which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method may be performed by a terminal device, wherein the terminal device may be the terminal device 120 or the terminal device 130 in the network architecture shown in FIG1 . The method may include the following steps:

[0102] Step 701: Receive discontinuous reception DRX configuration information; wherein the DRX configuration information is used to configure one of the following: N non-identical DRX cycle values, each DRX cycle value in the N non-identical DRX cycle values ​​corresponds to one or more of Q DRX cycles, and N and Q are integers greater than or equal to 2; a first DRX time period, the first DRX time period includes M second DRX time periods with non-identical durations, and M is an integer greater than or equal to 2; a first DRX cycle, the duration of the first DRX cycle is a non-integer value greater than zero.

[0103] In some embodiments, when the DRX configuration information is used to configure N non-identical DRX cycle values, the values ​​of N and Q may be the same, or the values ​​of N and Q may be different, such as N<Q; in addition, the N non-identical DRX cycle values ​​may be partially different or different (i.e., completely different).

[0104] For example, when the N DRX cycle values ​​are not exactly the same and the values ​​of N and Q are the same, the N DRX cycle values ​​can be {16, 17, 17} respectively, in ms. Correspondingly, the durations of the Q DRX cycles are 16ms, 17ms, and 17ms respectively.

[0105] For another example, when N DRX cycle values ​​are different and N is less than Q, assuming that the N DRX cycle values ​​are {16, 17}, the unit is ms, the value of Q is 3, and the first DRX cycle in the Q DRX cycles corresponds to the first DRX cycle value, and the next two DRX cycles correspond to the second DRX cycle value, then the durations of the Q DRX cycles are 16ms, 17ms, and 17ms respectively.

[0106] In some embodiments, when the DRX configuration information is used to configure the first DRX time period, the first DRX time period includes M second DRX time periods of different lengths, which can be M time periods with partially different lengths, or M time periods with different lengths. For example, taking the value of M as 3, the lengths of the M second DRX time periods can be 16ms, 17ms, and 17ms, respectively, or the lengths of the M second DRX time periods can be 15ms, 17ms, and 18ms, respectively.

[0107] The solution in the embodiment of the present application is applicable to at least the following DRX enhancement method:

[0108] DRX enhancement method 1: through protocol agreement, or the network side configures at least two cycle values ​​(or a cycle pattern), at least two cycle values ​​corresponding to different DRX cycles of a DRX configuration;

[0109] In the first DRX enhancement method, there may be no concept of "DRX cycle combination", but only at least two cycle values, and the at least two cycle values ​​correspond to different DRX cycles, that is, the at least two cycle values ​​appear in a certain pattern.

[0110] DRX enhancement method 2: Through protocol agreement or network-side configuration of multiple DRX start offsets, multiple DRX start offsets correspond to the same DRX cycle in a DRX configuration. The DRX cycle can be divided into multiple DRX sub-cycles based on the multiple DRX start offsets (the protocol does not necessarily use the descriptions of "DRX cycle" and "DRX sub-cycle". For example, a first DRX period may contain multiple second DRX periods).

[0111] DRX enhancement method three: through protocol agreement, or the network side configures a non-integer DRX cycle, such as 50 / 3ms (~16.17ms), 100 / 3ms (~33.33ms), 25 / 3ms (~8.33ms).

[0112] Step 702: In the DRX mode corresponding to the DRX configuration information, perform at least one of the following: radio link monitoring; receiving a reference signal; and physical downlink control channel (PDCCH) monitoring.

[0113] To sum up, the embodiments of the present application provide a scheme for a terminal device to perform at least one of wireless link monitoring, reference signal reception and PDCCH monitoring when configured with N non-identical DRX cycle values, a first DRX time period including M second DRX time periods with non-identical durations, or a first DRX cycle with a duration of a non-integer value greater than zero. This scheme makes wireless communication behaviors such as wireless link monitoring, reference signal reception and PDCCH monitoring more applicable in the above three enhanced DRX modes, expands the DRX modes applicable to wireless transmission behaviors such as wireless link monitoring, reference signal reception and PDCCH monitoring, optimizes the wireless communication process, and improves the data transmission efficiency under the DRX mechanism.

[0114] Please refer to FIG8 , which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method may be performed by a network device, wherein the network device may be the network device 110 in the network architecture shown in FIG1 . The method may include the following steps:

[0115] Step 801: Send discontinuous reception DRX configuration information, where the DRX configuration information is used to configure one of the following: N non-identical DRX cycle values, each DRX cycle value in the N non-identical DRX cycle values ​​corresponds to one or more of Q DRX cycles, where N and Q are integers greater than or equal to 2; a first DRX time period, where the first DRX time period includes M DRX time periods with non-identical durations, where M is an integer greater than or equal to 2; and a first DRX cycle, where the duration of the first DRX cycle is a non-integer value greater than zero.

[0116] Step 802, in the DRX mode corresponding to the DRX configuration information, perform at least one of the following: configure a first period to the terminal device, the first period is used for the terminal device to perform wireless link monitoring according to the first period; send a reference signal to the terminal device; and send PDCCH to the terminal device.

[0117] In summary, the embodiments of the present application provide a scheme for a network device to perform at least one of wireless link monitoring cycle configuration, reference signal reception, and PDCCH monitoring when the terminal device is configured with N non-identical DRX cycle values, a first DRX time period including M second DRX time periods with non-identical durations, or a first DRX cycle with a duration of a non-integer value greater than zero. This scheme makes wireless communication behaviors such as wireless link monitoring, reference signal reception, and PDCCH monitoring more applicable in the above three enhanced DRX modes, expands the DRX modes applicable to wireless transmission behaviors such as wireless link monitoring, reference signal reception, and PDCCH monitoring, optimizes the wireless communication process, and improves the data transmission efficiency under the DRX mechanism.

[0118] In the case where the above-mentioned signal processing includes monitoring of the wireless link, based on the schemes shown in Figures 7 and 8 above, please refer to Figure 9, which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method can be interactively executed by a terminal device and a network device; wherein the above-mentioned terminal device and network device can be the terminal device 120 and network device 110 in the network architecture shown in Figure 1; or, the above-mentioned terminal device and network device can be the terminal device 130 and network device 110 in the network architecture shown in Figure 1. As shown in Figure 9, the method can include the following steps:

[0119] Step 901: The network device sends DRX configuration information to the terminal device; the terminal device receives the DRX configuration information.

[0120] In some embodiments, the DRX configuration information is used to configure one of the following: N non-identical DRX cycle values, each DRX cycle value in the N non-identical DRX cycle values ​​corresponds to one or more of Q DRX cycles, N and Q are integers greater than or equal to 2; a first DRX time period, the first DRX time period includes M DRX time periods with non-identical durations, M is an integer greater than or equal to 2; a first DRX cycle, the duration of the first DRX cycle is a non-integer value greater than zero.

[0121] In some embodiments, when the DRX configuration information is used to configure N unequal DRX cycle values, Q DRX cycles constitute a DRX cycle combination.

[0122] The above-mentioned DRX cycle combination may be a DRX cycle pattern.

[0123] For example, when the N DRX cycle values ​​are not exactly the same and the values ​​of N and Q are the same, the N DRX cycle values ​​are {16, 17, 17}, and the durations of the Q DRX cycles are 16 ms, 17 ms, and 17 ms, respectively. The Q DRX cycles can constitute a cycle combination, and the total duration of the cycle combination is less than 50 ms.

[0124] In some embodiments, when the DRX configuration information is used to configure the first DRX period, the M second DRX periods correspond to M DRX activation timers, and the time domain positions of the M DRX activation timers are determined according to M starting offsets.

[0125] The above-mentioned time domain position may be the position of the time domain resource corresponding to the start time of the DRX activation timer, such as a time slot position or a symbol position.

[0126] For example, corresponding to FIG5 , a DRX cycle includes three DRX activation timers, and the time domain position (eg, start time) of each DRX activation timer is determined by one of three DRX start offsets.

[0127] The terminal device may subsequently perform wireless link monitoring through step 902 or step 903.

[0128] Step 902: In the DRX mode corresponding to the above-mentioned DRX configuration information, the terminal device performs radio link monitoring according to a first period, where the first period is determined based on a second period related to the DRX configuration information.

[0129] In some embodiments, the first period may also be determined solely based on the second period. For example, the terminal device may directly use the second period as the first period.

[0130] In some other embodiments, the first period is determined according to the second period and a period associated with a radio link monitoring RLM resource.

[0131] The terminal device can comprehensively determine the first period of the above-mentioned wireless link monitoring by combining the second period and the period related to the RLM resource.

[0132] In some embodiments, the first period is a maximum or minimum value of the second period and a period associated with the RLM resource.

[0133] The terminal device may take the maximum or minimum value of the second period and the period related to the RLM resource to obtain the first period. The maximum or minimum value of the period related to the RLM resource may be the maximum or minimum value of the period values ​​(or values ​​or durations) of the period related to the RLM resource. In other words, the period value of the first period is the maximum or minimum value of the period values ​​(or values ​​or durations) of the second period and the period related to the RLM resource.

[0134] In some embodiments, when multiple RLM resources are configured, the period associated with the RLM resource is the maximum or minimum value among multiple periods corresponding to the multiple RLM resources.

[0135] Among them, the terminal device can be configured with multiple RLM resources. At this time, the terminal device can determine a period related to the above-mentioned RLM resource from multiple periods corresponding to multiple RLM resources, for example, take the minimum value of the periods corresponding to multiple RLM resources as the period related to the above-mentioned RLM resource.

[0136] In some embodiments, when multiple RLM resources are configured, the period associated with the RLM resource may also be the maximum value among the periods corresponding to the multiple RLM resources, or the average value of the periods corresponding to the multiple RLM resources rounded off; in some embodiments, the rounding method may include rounding up, rounding down, or rounding off.

[0137] Among them, for the above-mentioned DRX enhancement methods one to three, the determination method of the above-mentioned second period may be different.

[0138] For DRX enhancement method 1:

[0139] In some embodiments, when the DRX configuration information is used to configure N DRX cycle values ​​that are not completely the same, the duration of the second cycle is determined according to the N DRX cycle values ​​that are not completely the same.

[0140] In the DRX enhancement method, the terminal device can determine the second cycle based on N DRX cycle values ​​with different durations.

[0141] In some embodiments, the duration of the second cycle is the maximum value among N DRX cycle values ​​with different durations.

[0142] In some embodiments, the duration of the second cycle is the minimum value among N DRX cycle values ​​with different durations.

[0143] In some embodiments, when each of the Q DRX cycles corresponds to a second cycle, the duration of the second cycle is the DRX cycle value of the DRX cycle corresponding to the second cycle.

[0144] In the DRX method, multiple second cycles may correspond one-to-one with Q DRX cycles in the time domain, and the duration of each second cycle may be the same as the DRX cycle value of the corresponding DRX cycle. For example, a DRX cycle pattern may consist of three DRX cycles, and the cycle values ​​of the three DRX cycles are 16ms, 17ms, and 17ms, respectively. The terminal device may then determine three second cycles corresponding to the three DRX cycles, and the durations of the three second cycles may be 16ms, 17ms, and 17ms, respectively. In other words, the durations of the second cycles may not be exactly the same within different time ranges.

[0145] In some embodiments, the three second cycles are aligned with the three DRX cycles in the time domain.

[0146] In some embodiments, the duration of the second cycle is the j-th DRX cycle value among N DRX cycle values ​​with different durations, where j is an integer and 1≤j≤N.

[0147] For example, the duration of the second cycle may be the first or last DRX cycle value among N DRX cycle values ​​with different durations, and the durations of different second cycles may be the same.

[0148] In some embodiments, when the DRX configuration information is used to configure N unequal DRX cycle values, the duration of the second cycle is determined according to the sum of the DRX cycle values ​​corresponding to the Q DRX cycles.

[0149] For example, the terminal device may also determine the duration of the entire DRX cycle pattern as the duration of the above-mentioned second cycle.

[0150] For DRX enhancement method 2:

[0151] In some embodiments, when the DRX configuration information is used to configure the first DRX period, the duration of the second cycle is determined according to M durations corresponding to the M second DRX periods.

[0152] Among them, under the DRX enhancement method 2, the terminal device can determine the second cycle according to the M durations corresponding to the M second DRX time periods in the first DRX time period.

[0153] In some embodiments, the duration of the second period is the maximum value among the M durations; or,

[0154] The duration of the second cycle is the minimum value among the M durations; or,

[0155] In the case where each of the M second DRX time periods corresponds to a second cycle, the duration of the second cycle is the duration of the second DRX time period corresponding to the second cycle; wherein, under DRX method 2, multiple second cycles can correspond one-to-one with the M second DRX time periods in the time domain, and the duration of each second cycle is the same as the duration of a corresponding second DRX time period. For example, a first DRX time period is divided into three second DRX time periods by the DRX start offset, and the durations of the three second DRX time periods are 16ms, 17ms, and 17ms, respectively; then the terminal device determines three second cycles corresponding to the three second DRX time periods, and the durations of the three second cycles are 16ms, 17ms, and 17ms, respectively. That is to say, in different time ranges, the durations of the second cycles may not be exactly the same; in some embodiments, the above three second cycles are aligned with the three second DRX time periods in the time domain;

[0156] Alternatively, the duration of the second cycle is the duration of the i-th second DRX time period among M second DRX time periods, where i is an integer and 1≤i≤M; for example, the duration of the above-mentioned second cycle can be the length of the first or last second DRX time period among the M second DRX time periods, and the durations of different second cycles can be the same.

[0157] In some embodiments, when the DRX configuration information is used to configure the first DRX period, the duration of the second cycle is determined according to the duration of the first DRX period.

[0158] For example, the terminal device may also determine the duration of the entire first DRX time period as the duration of the above-mentioned second cycle.

[0159] For DRX enhancement method three:

[0160] In some embodiments, when the DRX configuration information is used to configure the first DRX cycle, the duration of the second cycle is determined according to the duration of the first DRX cycle.

[0161] Among them, under the DRX enhancement method three, the terminal device can directly determine the duration of the above-mentioned second cycle based on the first DRX cycle currently configured by the terminal device.

[0162] In some embodiments, the duration of the second cycle is the duration of the first DRX cycle; or,

[0163] The duration of the second cycle is an integer determined by the duration of the first DRX cycle, such as a value rounded up, rounded down, or rounded off.

[0164] Among them, the terminal device can directly use the duration of the first DRX cycle as the duration of the second cycle, or the terminal device can also round up or decimalize the duration of the first DRX cycle to obtain the duration of the second cycle.

[0165] That is, the terminal device may use the duration of the previous or next integer value of the duration of the first DRX cycle as the duration of the second cycle.

[0166] The granularity of the rounding or rounding can be ms level (subframe level), slot level, or symbol level. For example, when the duration of the first DRX cycle is 16.67 ms, the rounded or rounded value is 16 ms or 17 ms; for another example, when the duration of the first DRX cycle is 16.67 slots, the rounded or rounded value is 16 slots or 17 slots; for another example, when the duration of the first DRX cycle is 233.38 symbols, the rounded or rounded value is 233 symbols or 234 symbols.

[0167] Step 903: In the mode corresponding to the above-mentioned DRX configuration information, the terminal device performs wireless link monitoring according to the first period, and the first period is determined according to at least one of the following periods: the period of RLM resources; the predefined period; and the period of network configuration.

[0168] In some embodiments, in any of the above-mentioned DRX enhancement methods one to three, the terminal device may not determine the first period based on the DRX configuration information. For example, the terminal device determines the first period based on the period of the RLM resource, a predefined period and / or a network configured period.

[0169] For example, the terminal device determines the period of the RLM resource as the first period, or the terminal device determines the predefined period as the first period, or the terminal device determines the period configured by the network as the second period, or the terminal device determines the maximum or minimum value among the period of the RLM resource, the predefined period and the period configured by the network as the first period.

[0170] In some embodiments, when the terminal device determines that the first period is a period configured by the network device, the network device may configure the first period for the terminal device before step 903 .

[0171] Based on the solution shown in the embodiment of the present application, in the DRX mode corresponding to the above-mentioned DRX configuration information, the terminal device evaluates the radio link quality once in each first period, and the first period is determined according to at least one of the following:

[0172] 1) The shortest period of wireless link monitoring resources;

[0173] 2) The second cycle is related to DRX.

[0174] Specifically, the implementation may include: determining based only on 1), or determining based on the maximum / minimum value of 1) and 2).

[0175] The second period is determined according to at least one of the following:

[0176] 1) (corresponding to DRX enhancement method 1): the maximum / minimum value of at least two cycle values ​​(or at least two cycle values ​​included in a cycle pattern); this method reports IS / OOS more promptly.

[0177] 2) (corresponding to DRX enhancement method 2): DRX cycle (or the first DRX time period); this method lengthens the reporting cycle, can save power of the terminal device, and has a better energy-saving effect.

[0178] 3) (Corresponding to DRX enhancement methods 1 and 2) at least two cycle values, a cycle pattern, and the length of at least one second DRX period.

[0179] Further, within different time ranges, the second period is determined according to one of at least two period values, or one of the period patterns, or one of the length values ​​of at least one second DRX period;

[0180] This solution can ensure that the reported IS / OOS falls within the DRX active time while also taking into account the advantage of energy saving.

[0181] 4) (corresponding to DRX enhancement method three): the duration of the first DRX cycle, or other values ​​determined based on the duration of the first DRX cycle, such as the value after rounding up / down / rounding off the duration of the first DRX cycle.

[0182] 5) The second cycle is agreed upon by the protocol or configured, and may be independent of the DRX cycle.

[0183] In one embodiment, assuming that the frame rate of the XR service is 1 / 60fps and the network side is configured with enhanced DRX, the enhancement method is as described in Methods 1 to 3 above. The physical layer of the terminal device evaluates the radio link quality once in each reporting period and reports it to the upper layer of the terminal device. The terminal device determines the reporting period in the following manner: the maximum value between the shortest period of all configured RLM-RS resource periods and the DRX-related period. The "DRX-related period" is determined in the following manner:

[0184] (Corresponding to DRX enhancement method 1): min{16ms, 17ms}=16ms or max{16ms, 17ms}=17ms.

[0185] (Corresponding to DRX enhancement method 2): 50ms.

[0186] (Corresponding to DRX enhancement methods 1 and 2) One of 16ms and 17ms:

[0187] The "DRX-related period" appears according to the pattern of "16ms, 17ms, 17ms", that is, the reporting period appears according to the pattern of "max{RLM-RS resource shortest period, 16ms}, max{RLM-RS resource shortest period, 17ms}, max{RLM-RS resource shortest period, 17ms}". The position of the pattern is determined by the DRX configuration parameters, such as the DRX start offset.

[0188] (Corresponding to DRX enhancement method 3): 16.67ms, or 50 / 3ms, or or, Or, round(16.67ms)=17ms.

[0189] (Universal): Directly set to Xms through protocol agreement or network-side configuration.

[0190] Another implementation is that, even if the terminal device is configured with DRX, the terminal device determines the reporting period only according to the configured RLM-RS resource period, not according to the DRX period, for example:

[0191] Determine the reporting period as the shortest period among the periods of all configured RLM-RS resources; or,

[0192] Determine the reporting period to be the period of the configured RLM-RS resource, where RLM-RS is a dedicated RS in the DRX scenario; or,

[0193] Make sure the reporting period is the reporting period configured on the network device.

[0194] In summary, an embodiment of the present application provides a scheme for a terminal device to perform wireless link monitoring when configured with N non-identical DRX cycle values, a first DRX time period including M second DRX time periods with non-identical durations, or a first DRX cycle with a duration of a non-integer value greater than zero. This scheme makes wireless communication behaviors such as wireless link monitoring, receiving reference signals, and PDCCH monitoring more applicable in the above three enhanced DRX modes, expands the DRX modes applicable to wireless transmission behaviors such as wireless link monitoring, receiving reference signals, and PDCCH monitoring, optimizes the wireless communication process, and improves the data transmission efficiency under the DRX mechanism.

[0195] In the case where the above-mentioned signal processing includes PDCCH monitoring, based on the schemes shown in Figures 7 and 8 above, please refer to Figure 10, which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method can be interactively executed by a terminal device and a network device; wherein the above-mentioned terminal device and network device can be the terminal device 120 and network device 110 in the network architecture shown in Figure 1; or, the above-mentioned terminal device and network device can be the terminal device 130 and network device 110 in the network architecture shown in Figure 1. As shown in Figure 10, the method can include the following steps:

[0196] Step 1001: The network device sends DRX configuration information to the terminal device; the terminal device receives the DRX configuration information.

[0197] The DRX configuration information is used to configure one of the following: N non-identical DRX cycle values, each DRX cycle value in the N non-identical DRX cycle values ​​corresponds to one or more of Q DRX cycles, where N and Q are integers greater than or equal to 2; a first DRX period, where the first DRX period includes M second DRX periods with non-identical durations, where M is an integer greater than or equal to 2; a first DRX cycle, where the duration of the first DRX cycle is a non-integer value greater than zero;

[0198] In some embodiments, when the DRX configuration information is used to configure N unequal DRX cycle values, Q DRX cycles constitute a DRX cycle combination.

[0199] In some embodiments, when the DRX configuration information is used to configure the first DRX period, the M second DRX periods correspond to M DRX activation timers, and the time domain positions of the M DRX activation timers are determined according to M starting offsets.

[0200] Step 1002: In the DRX mode corresponding to the above-mentioned DRX configuration information, the network device sends a PDCCH carrying the first DCI to the above-mentioned terminal device within a first time range; the above-mentioned first DCI is used to indicate whether the above-mentioned terminal device starts the first timer within the third period; the above-mentioned first timer is a DRX activation timer.

[0201] Step 1003: In the DRX mode corresponding to the above-mentioned DRX configuration information, the terminal device monitors the PDCCH carrying the first DCI within a first time range.

[0202] Among them, for the above-mentioned DRX enhancement methods one to three, the determination method of the above-mentioned third period and the indication method of the first DCI may be different.

[0203] For DRX enhancement method 1 or method 2:

[0204] In some embodiments, when the DRX configuration information is used to configure a first DRX period or N non-identical DRX cycle values,

[0205] The third cycle includes a second DRX time period or a DRX cycle; the first time range is determined by a second start time and a second offset; the above-mentioned second start time is the start time of the DRX activation timer corresponding to the above-mentioned second DRX time period, or the start time of the DRX activation timer corresponding to the above-mentioned DRX cycle.

[0206] The second DRX time period or DRX cycle included in the third cycle may be a second DRX time period generally referred to in the first DRX time period, or a DRX cycle generally referred to in the Q DRX cycles. Specifically, the third cycle may include any second DRX time period or any DRX cycle.

[0207] Among them, the terminal device can monitor the PDCCH for each second DRX time period in the second DRX enhancement method, or for each DRX cycle in the first DRX enhancement method.

[0208] In some embodiments, the first timer includes a DRX activation timer corresponding to the second DRX time period or a DRX activation timer corresponding to the DRX cycle.

[0209] In some embodiments, the start time of the first time range is before the second start time, and the interval between the start time of the first time range and the second start time is a second offset.

[0210] For example, the start time of the DRX activation timer corresponding to the second DRX time period or DRX cycle is T1, and the second offset is t. Then the start time of the first time range is T2 before T1, and the duration interval between T1 and T2 is t.

[0211] In some embodiments, the first DCI is used to indicate whether to start a DRX activation timer corresponding to a next second DRX period or a next DRX cycle after the current moment. The current moment may be the moment when the first DCI is received, for example, the current moment may be the time slot or symbol position at which the first DCI is received.

[0212] The terminal device may start monitoring the PDCCH in each second DRX time period in the second DRX enhancement method, or in an offset period before each DRX cycle in the first DRX enhancement method.

[0213] For DRX enhancement method 1 or method 2:

[0214] In some embodiments, when the DRX configuration information is used to configure the first DRX time period or N non-identical DRX cycle values, the third cycle includes the first DRX time period or Q DRX cycles (that is, the third cycle includes a DRX cycle combination consisting of Q DRX cycles); the first time range is determined by the first start time and the first offset; the above-mentioned first start time is the start time of the first DRX activation timer corresponding to the above-mentioned first DRX time period, or the start time of the first DRX activation timer corresponding to the above-mentioned Q DRX cycles.

[0215] Among them, the terminal device can monitor the PDCCH for the first DRX time period in the second DRX enhancement method, or for the DRX cycle combination consisting of Q DRX cycles in the first DRX enhancement method.

[0216] In some embodiments, the first timer includes all DRX activation timers corresponding to the first DRX period or part of all DRX activation timers corresponding to the Q DRX cycles; or

[0217] The first timer includes all DRX activation timers corresponding to the first DRX period or all DRX activation timers corresponding to the Q DRX cycles.

[0218] The first DCI may indicate whether all or some of the DRX activation timers in the first DRX period or DRX cycle combination are started. For example, the network side device may indicate whether all or some of the DRX activation timers in the first DRX period or DRX cycle combination are started at once through the first DCI.

[0219] In some embodiments, the start time of the first time range is before the first start time, and the interval between the start time of the first time range and the first start time is a first offset.

[0220] The terminal device may start monitoring the PDCCH in the first DRX time period in the second DRX enhancement method, or in an offset period before the entire DRX cycle combination in the first DRX enhancement method.

[0221] In some embodiments, the first DCI includes first indication information, where the first indication information is used to indicate: whether to start all DRX activation timers corresponding to the first DRX period or all DRX activation timers corresponding to the Q DRX cycles, or whether to start the DRX activation timer of at least one specified position among all DRX activation timers corresponding to the first DRX period or all DRX activation timers corresponding to the Q DRX cycles; or

[0222] The above-mentioned first DCI includes multiple second indication information, and the above-mentioned multiple second indication information corresponds one-to-one to all DRX activation timers corresponding to the above-mentioned first DRX time period or all DRX activation timers corresponding to the above-mentioned Q DRX cycles. Each of the above-mentioned second indication information is used to indicate whether to start the DRX activation timer corresponding to each of the above-mentioned second indication information.

[0223] In which, the terminal device can indicate whether all or part of the DRX activation timers in the first DRX time period or DRX cycle combination are started through a single indication information; for example, assuming that the above-mentioned first DRX time period or DRX cycle combination corresponds to 3 DRX activation timers, the single indication information contained in the above-mentioned first DCI is 0 or 1, wherein, when the indication information is 0, it indicates that all the above-mentioned 3 DRX activation timers are not started, and when the indication information is 1, it indicates that all the above-mentioned 3 DRX activation timers are started; or, when the indication information is 0, it indicates that the first DRX activation timer or the first two DRX activation timers among the above-mentioned 3 DRX activation timers are not started, and when the indication information is 1, it indicates that the first DRX activation timer or the first two DRX activation timers among the above-mentioned 3 DRX activation timers are started.

[0224] Alternatively, the terminal device may also indicate whether all or part of the DRX activation timers in the first DRX time period or DRX cycle combination are started through multiple indication information. For example, assuming that the above-mentioned first DRX time period or DRX cycle combination corresponds to 3 DRX activation timers, the first DCI contains multiple indication information 3 indication information, wherein the first indication information is used to indicate whether to start the first DRX activation timer, the second indication information is used to indicate whether to start the second DRX activation timer, and the third indication information is used to indicate whether to start the third DRX activation timer; for example, if the three indication information contained in the first DCI are {0, 1, 1}, it indicates that the first DRX activation timer of the three DRX activation timers is not started, and the second and third DRX activation timers are started.

[0225] Each of the above indication information may occupy 1 bit.

[0226] For DRX enhancement method three:

[0227] In some embodiments, when the DRX configuration information is used to configure the first DRX cycle,

[0228] The third cycle is determined according to the first DRX cycle; the first time range is determined according to the third start time and the third offset; the third start time is the start time of the DRX activation timer corresponding to the third cycle.

[0229] In some embodiments, the start time of the first time range is before the third start time, and the interval between the start time of the first time range and the third start time is a third offset.

[0230] In some embodiments, the first DCI is used to indicate whether to start the DRX activation timer corresponding to the next third cycle after the current moment. The current moment may be the moment when the first DCI is received.

[0231] Under the above-mentioned DRX enhancement method three, the terminal device can receive the first DCI for each first DRX cycle, and the terminal device starts monitoring the PUCCH containing the first DCI at a time offset before the third cycle corresponding to each first DRX cycle.

[0232] In some embodiments, the duration of the third cycle is the duration of the first DRX cycle, or an integer value determined based on the duration of the first DRX cycle, such as an integer value obtained by rounding up, rounding down, or rounding off.

[0233] The granularity of the rounding or integer division may be ms level (subframe level), slot level, or symbol level.

[0234] In the above-mentioned wireless communication process between the terminal device and the network device, the terminal device and the network device can respectively execute the process of determining the above-mentioned third period.

[0235] The embodiment of the present application provides a configuration and monitoring solution for an energy-saving wake-up signal, taking DRX enhancement method 2 as an example:

[0236] When the terminal device is configured with DRX, the terminal device monitors a first DCI (DCI format 2_6) within a first time range, where the first DCI is used to indicate whether the terminal device starts a first timer within a third period;

[0237] The first time range is determined according to at least one of the following: the start time of the second timer, the first offset, that is, the terminal device starts monitoring the first DCI from the first offset before the start time of the second timer, the second timer is the first timer, or one of the first timers.

[0238] Implementation method 1: The third cycle is the first DRX time period in the DRX enhancement method 2, the first timer is all DRX-onduration timers in the first DRX time period, and the terminal device starts monitoring the first DCI at the first offset before the start time of the first DRX onduration timer in the first DRX time period. The first DCI is used to indicate whether the terminal device starts the first timer (all DRX onduration timers in the first DRX time period):

[0239] - Implementation 1-1: The first DCI includes 1-bit indication information, indicating whether the terminal device starts all DRX onduration timers in the first DRX period, or indicating whether the terminal device starts the first DRX onduration timer in the first DRX period;

[0240] - Implementation 1-2: The first DCI includes N bits of indication information, which can independently instruct the terminal device to start certain DRX onduration timers and / or not start certain DRX onduration timers within the first DRX period; for example, N is a bitmap, the value of N is equal to the number of DRX onduration timers within the first DRX period, and each bit indicates whether the terminal device starts the DRX onduration timer corresponding to the bit;

[0241] Implementation method two: The third cycle is the second DRX time period in DRX enhancement method two, the first timer is the DRX-on duration timer in the second DRX time period, and the terminal device starts monitoring the first DCI at the first offset before the start time of the DRX-on duration timer in each second DRX time period. The first DCI is used to indicate whether the terminal device starts the DRX-onduration timer in the next second DRX time period after the first DCI.

[0242] This solution is necessary to clarify the issues that must be addressed when introducing the above-mentioned DRX enhancement method 2, where:

[0243] In implementations 1-1 and 1-2, the terminal device monitors DCI format 2_6 at longer time intervals, which can save energy consumption of the terminal device, and the behavior of monitoring DCI format 2_6 can be maintained periodically;

[0244] In the second implementation, the terminal device monitors DCI format 2_6 at shorter time intervals, which can timely and flexibly indicate whether the terminal device starts each on duration, achieving the highest timeliness and flexibility.

[0245] In one embodiment, assuming that the frame rate of the XR service is 1 / 60fps and the network side is configured with enhanced DRX, the enhancement method is as described in the above method 2, that is, three start offsets are configured / predefined within a 50ms period, and the positions of the three DRX-onduration timers are determined thereby, and the three second DRX time periods can also be determined to be 16ms, 17ms, and 17ms respectively. Please refer to Figure 11, which shows a PDCCH monitoring schematic diagram involved in an embodiment of the present application. As shown in Figure 11, the terminal is configured to monitor DCI format 2_6:

[0246] - According to implementation 1-1: the terminal starts monitoring DCI format 2_6 at the first offset before the first on-duration timer of the first DRX period of 50 ms. DCI format 2_6 contains a 1-bit wake-up information bit. If the bit is "1", the physical layer of the terminal reports to the upper layer of the terminal to start the three DRX-onduration timers in the next 50 ms first DRX period, or the first DRX-onduration timer in the next 50 ms first DRX period. If the bit is "0", the physical layer of the terminal reports to the upper layer of the terminal not to start the three DRX-onduration timers in the next 50 ms DRX period, or the first DRX-onduration timer in the next 50 ms first DRX period.

[0247] - According to implementation 1-2: the terminal starts monitoring DCI format 2_6 at the first offset before the first on-duration timer of the first DRX period of 50 ms. DCI format 2_6 contains 3 wake-up information bits, which correspond to the three DRX-on-duration timers in the next 50 ms first DRX period. For example, if the 3-bit wake-up information is "101", the terminal starts the first and third DRX-on-duration timers in the next 50 ms first DRX period, but does not start the second DRX-on-duration timer.

[0248] In another embodiment, assuming that the frame rate of the XR service is 1 / 60fps and the network side is configured with enhanced DRX, the enhancement method is as described in the above method 2, that is, three start offsets are configured / predefined within the first DRX period of 50ms, and the positions of the three DRX-onduration timers are determined thereby, and the three DRX sub-cycles can also be determined to be 16ms, 17ms, and 17ms respectively. Please refer to Figure 12, which shows a PDCCH monitoring schematic diagram involved in an embodiment of the present application. As shown in Figure 12, the terminal is configured to monitor DCI format 2_6:

[0249] According to implementation method 2: the terminal starts monitoring DCI format 2_6 at the first offset before each on duration timer in the first DRX period of 50ms. DCI format 2_6 contains 1 wake-up information bit. If it is "1", the physical layer of the terminal reports to the upper layer of the terminal to start the DRX-onduration timer in the next 16ms or 17ms second DRX period. If it is "0", the physical layer of the terminal reports to the upper layer of the terminal and does not start the DRX-onduration timer in the next 16ms or 17ms second DRX period.

[0250] To sum up, the embodiments of the present application provide a scheme for a terminal device to perform PDCCH monitoring when configured with N non-identical DRX cycle values, a first DRX time period including M second DRX time periods with non-identical durations, or a first DRX cycle with a duration of a non-integer value greater than zero. This makes wireless communication behaviors such as PDCCH monitoring more applicable in the above three enhanced DRX modes, expands the DRX modes applicable to wireless transmission behaviors such as PDCCH monitoring, optimizes the wireless transmission process, and improves the data transmission efficiency under the DRX mechanism.

[0251] In the case where the above-mentioned signal processing includes receiving a reference signal, based on the schemes shown in Figures 7 and 8 above, please refer to Figure 13, which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method can be interactively executed by a terminal device and a network device; wherein the above-mentioned terminal device and network device can be the terminal device 120 and network device 110 in the network architecture shown in Figure 1; or, the above-mentioned terminal device and network device can be the terminal device 130 and network device 110 in the network architecture shown in Figure 1. As shown in Figure 13, the method can include the following steps:

[0252] Step 1301: The network device sends DRX configuration information to the terminal device; the terminal device receives the DRX configuration information.

[0253] The DRX configuration information is used to configure one of the following: N non-identical DRX cycle values, each DRX cycle value in the N non-identical DRX cycle values ​​corresponds to one or more of Q DRX cycles, where N and Q are integers greater than or equal to 2; a first DRX period, where the first DRX period includes M second DRX periods with non-identical durations, where M is an integer greater than or equal to 2; a first DRX cycle, where the duration of the first DRX cycle is a non-integer value greater than zero;

[0254] In some embodiments, when the DRX configuration information is used to configure N unequal DRX cycle values, Q DRX cycles constitute a DRX cycle combination.

[0255] In some embodiments, when the DRX configuration information is used to configure the first DRX period, the M second DRX periods correspond to M DRX activation timers, and the time domain positions of the M DRX activation timers are determined according to M starting offsets.

[0256] The network device and the terminal device may subsequently send and receive the reference signal through one of steps 1302 , 1303 , and 1304 .

[0257] Step 1302: In the DRX mode corresponding to the above-mentioned DRX configuration information, the network device sends a reference signal to the above-mentioned terminal device according to a fourth period, and the terminal device receives the reference signal according to the fourth period, and the fourth period is determined according to the DRX configuration information.

[0258] In some embodiments, when the duration of the fourth period exceeds the first threshold, the terminal device does not expect the channel state information reference signal CSI-RS resources to be available outside the second time range; the second time range is determined based on the CSI-RS resource configuration parameters for mobility.

[0259] Correspondingly, when the duration of the above-mentioned fourth cycle exceeds the first threshold, the network device does not send the CSI-RS of the above-mentioned terminal device on the channel state information reference signal CSI-RS resources outside the second time range, or the network device does not configure the CSI-RS resources of the above-mentioned terminal device outside the above-mentioned second time range; the above-mentioned second time range is determined based on the CSI-RS resource configuration parameters for mobility.

[0260] Alternatively, the network device may also send the CSI-RS of the terminal device on the channel state information reference signal CSI-RS resources outside the second time range, or the network device may configure the CSI-RS resources of the terminal device outside the second time range.

[0261] Among them, for the above-mentioned DRX enhancement methods one to three, the determination method of the above-mentioned fourth period may be different.

[0262] For DRX enhancement method 1:

[0263] In some embodiments, when the DRX configuration information is used to configure N DRX cycle values ​​that are not completely the same, the duration of the fourth cycle is determined according to the N DRX cycle values ​​that are not completely the same.

[0264] In the DRX enhancement method, the terminal device can determine the fourth cycle based on N DRX cycle values ​​with different durations.

[0265] In some embodiments, the duration of the fourth cycle is the maximum value among N DRX cycle values ​​with different durations.

[0266] In some embodiments, the duration of the fourth cycle is the minimum value among N DRX cycle values ​​with different durations.

[0267] In some embodiments, when each of the Q DRX cycles corresponds to a fourth cycle, the duration of the fourth cycle is the DRX cycle value of the DRX cycle corresponding to the fourth cycle.

[0268] In the DRX method, multiple fourth cycles may correspond one-to-one with Q DRX cycles in the time domain, and the duration of each fourth cycle may be the same as the DRX cycle value of the corresponding DRX cycle. For example, a DRX cycle pattern may consist of three DRX cycles, and the cycle values ​​of the three DRX cycles may be 16ms, 17ms, and 17ms, respectively. The terminal device may then determine three fourth cycles corresponding to the three DRX cycles, and the durations of the three fourth cycles may be 16ms, 17ms, and 17ms, respectively. In other words, the durations of the fourth cycles may not be exactly the same within different time ranges.

[0269] In some embodiments, the three fourth cycles are aligned with the three DRX cycles in the time domain.

[0270] In some embodiments, the duration of the fourth cycle is the j-th DRX cycle value among N DRX cycle values ​​with different durations, where j is an integer and 1≤j≤N.

[0271] For example, the duration of the fourth cycle may be the first or last DRX cycle value among N DRX cycle values ​​with different durations, and the durations of different fourth cycles may be the same.

[0272] In some embodiments, when the DRX configuration information is used to configure N unequal DRX cycle values, the duration of the fourth cycle is determined according to the sum of the DRX cycle values ​​corresponding to the Q DRX cycles.

[0273] For example, the terminal device may also determine the duration of the entire DRX cycle pattern as the duration of the fourth cycle mentioned above.

[0274] For DRX enhancement method 2:

[0275] In some embodiments, when the DRX configuration information is used to configure the first DRX period, the duration of the fourth cycle is determined according to M durations corresponding to the M second DRX periods.

[0276] Among them, under the DRX enhancement method 2, the terminal device can determine the fourth period according to the M durations corresponding to the M second DRX time periods in the first DRX time period.

[0277] In some embodiments, the duration of the fourth cycle is the maximum value among the M durations; or,

[0278] The duration of the fourth cycle is the minimum value among the M durations; or,

[0279] In the case where each of the M second DRX time periods corresponds to a fourth cycle, the duration of the fourth cycle is the duration of the second DRX time period corresponding to the fourth cycle; wherein, under DRX method 2, multiple fourth cycles can correspond one-to-one with the M second DRX time periods in the time domain, and the duration of each fourth cycle is the same as the duration of a corresponding second DRX time period. For example, a first DRX time period is divided into three second DRX time periods by the DRX start offset, and the durations of the three second DRX time periods are 16ms, 17ms, and 17ms, respectively; then the terminal device determines three fourth cycles corresponding to the three second DRX time periods, and the durations of the three fourth cycles are 16ms, 17ms, and 17ms, respectively. That is to say, in different time ranges, the durations of the fourth cycles may not be exactly the same; in some embodiments, the above three fourth cycles are aligned with the three second DRX time periods in the time domain;

[0280] Alternatively, the duration of the fourth cycle is the duration of the i-th second DRX time period among M second DRX time periods, where i is an integer and 1≤i≤M; for example, the duration of the above-mentioned fourth cycle can be the length of the first or last second DRX time period among the M second DRX time periods, and the durations of different fourth cycles can be the same.

[0281] In some embodiments, when the DRX configuration information is used to configure the first DRX period, the duration of the fourth cycle is determined according to the duration of the first DRX period.

[0282] For example, the terminal device may also determine the duration of the entire first DRX time period as the duration of the fourth cycle.

[0283] For DRX enhancement method three:

[0284] In some embodiments, when the DRX configuration information is used to configure the first DRX cycle, the duration of the fourth cycle is determined according to the duration of the first DRX cycle.

[0285] Among them, under the DRX enhancement method three, the terminal device can directly determine the duration of the above-mentioned fourth cycle based on the first DRX cycle currently configured by the terminal device.

[0286] In some embodiments, the duration of the fourth cycle is the duration of the first DRX cycle; or,

[0287] The duration of the fourth cycle is an integer determined by the duration of the first DRX cycle, such as a value rounded up, rounded down, or rounded off.

[0288] Among them, the terminal device can directly use the duration of the first DRX cycle as the duration of the fourth cycle, or the terminal device can also round up or decimalize the duration of the first DRX cycle to obtain the duration of the fourth cycle.

[0289] That is, the terminal device may use the duration of the previous or next integer value of the duration of the first DRX cycle as the duration of the fourth cycle.

[0290] The granularity of the rounding or rounding can be ms level (subframe level), slot level, or symbol level. For example, when the duration of the first DRX cycle is 16.67 ms, the rounded or rounded value is 16 ms or 17 ms; for another example, when the duration of the first DRX cycle is 16.67 slots, the rounded or rounded value is 16 slots or 17 slots; for another example, when the duration of the first DRX cycle is 233.38 symbols, the rounded or rounded value is 233 symbols or 234 symbols.

[0291] Step 1303, in the DRX mode corresponding to the above-mentioned DRX configuration information, the network device sends a reference signal to the terminal device according to the fifth period, and the terminal device receives the reference signal according to the fifth period, and the fifth period is determined according to at least one of the following: a predefined period; and a period configured by the network.

[0292] Among them, the terminal device can receive the reference signal according to the fifth period that is unrelated to the DRX configuration information.

[0293] In some embodiments, receiving a reference signal according to a fifth period includes:

[0294] When the duration of the fifth cycle exceeds the first threshold, the terminal device does not expect the channel state information reference signal CSI-RS resources to be available outside the second time range; the above-mentioned second time range is determined based on the CSI-RS resource configuration parameters for mobility.

[0295] Correspondingly, when the duration of the above-mentioned fifth cycle exceeds the first threshold, the network device does not send the CSI-RS of the above-mentioned terminal device on the channel state information reference signal CSI-RS resources outside the second time range, or the network device does not configure the CSI-RS resources of the above-mentioned terminal device outside the above-mentioned second time range; the above-mentioned second time range is determined based on the CSI-RS resource configuration parameters for mobility.

[0296] In some embodiments, when the duration of the above-mentioned fifth cycle exceeds the first threshold, the network device may send the CSI0-RS of the above-mentioned terminal device on the channel state information reference signal CSI-RS resources within the second time range, or the network device may configure the CSI-RS resources of the above-mentioned terminal device within the above-mentioned second time range.

[0297] In the above-mentioned wireless communication process between the terminal device and the network device, the terminal device and the network device can respectively execute the process of determining the above-mentioned fourth period or fifth period.

[0298] Step 1304: In the DRX mode corresponding to the above-mentioned DRX configuration information, the terminal device does not expect the channel state information reference signal CSI-RS resources to be available outside the second time range; the second time range is determined based on the CSI-RS resource configuration parameters for mobility.

[0299] In the DRX mode corresponding to the above-mentioned DRX configuration information, the terminal device may not expect CSI-RS resources outside the second time range to be available under any circumstances.

[0300] Correspondingly, in the DRX mode corresponding to the above-mentioned DRX configuration information, the network device does not send the CSI-RS of the above-mentioned terminal device on the channel state information reference signal CSI-RS resources outside the second time range, or the network device does not configure the CSI-RS resources of the above-mentioned terminal device outside the above-mentioned second time range.

[0301] In some embodiments, in the DRX mode corresponding to the above-mentioned DRX configuration information, the network device may send the CSI0-RS of the above-mentioned terminal device on the channel state information reference signal CSI-RS resources within the second time range, or the network device may configure the CSI-RS resources of the above-mentioned terminal device within the above-mentioned second time range.

[0302] An embodiment of the present application provides a solution for a terminal device to receive a CSI-RS for mobility according to a first configuration parameter, wherein the first configuration parameter includes: a DRX configuration parameter and a CSI-RS resource configuration parameter for mobility;

[0303] If the terminal is configured with DRX and the fourth cycle exceeds the first threshold, the terminal does not expect CSI-RS resources to be available outside a second time range, where the second time range is determined based on the CSI-RS resource configuration parameter for mobility;

[0304] The fourth period is determined according to at least one of the following:

[0305] 1) (corresponding to DRX enhancement method 1): the maximum / minimum value of at least two periodic values ​​(or at least two periodic values ​​included in a periodic pattern); this method receives the CSI-RS signal more timely.

[0306] 2) (corresponding to DRX enhancement method 2): DRX cycle (or first DRX time period); this method lengthens the period for receiving CSI-RS signals, which can save power of the terminal device and has a better energy-saving effect.

[0307] 3) (Corresponding to DRX enhancement methods 1 and 2) at least two cycle values, a cycle pattern, and the length of at least one second DRX period.

[0308] Further, within different time ranges, the fourth period is determined according to one of at least two period values, or one of the period patterns, or one of the length values ​​of at least one second DRX period;

[0309] This solution can ensure that the reception of CSI-RS signals falls within the DRX active time while also taking into account the advantages of energy saving.

[0310] 4) (corresponding to DRX enhancement method three): the duration of the first DRX cycle, or other values ​​determined based on the duration of the first DRX cycle, such as the value after rounding up / down / rounding off the duration of the first DRX cycle.

[0311] 5) The fourth cycle is agreed upon by the protocol or configured, and may be independent of the DRX cycle.

[0312] In one embodiment, assuming that the frame rate of the XR service is 1 / 30fps (≈33.33ms), and the network side is configured with enhanced DRX, the enhancement method is as shown in the above DRX enhancement method 1 to method 3. When the "DRX related period" exceeds 80ms, the terminal does not expect the CSI-RS to be available outside the measurement activation time determined by the CSI-RS-Resource-Mobility configuration. The "DRX related period" is determined by the following method:

[0313] (Corresponding to DRX enhancement method 1): min{33ms, 34ms}=33ms or max{33ms, 34ms}=34ms.

[0314] (Corresponding to DRX enhancement method 2): 100ms.

[0315] (Corresponding to DRX enhancement methods 1 and 2) One of 33ms and 34ms:

[0316] The "DRX-related period" appears according to the pattern of "33ms, 33ms, 34ms". The position of the pattern is determined by the DRX configuration parameters, such as the DRX start offset.

[0317] (Corresponding to DRX enhancement method 3): 33.33ms, or 100 / 3ms, or or, Or, round(33.33ms)=33ms.

[0318] (Universal): Directly set to Xms through protocol agreement or network-side configuration.

[0319] Another implementation is that even if the terminal is configured with DRX, no matter what the DRX cycle is, the terminal does not expect the CSI-RS to be available outside the measurement activation time determined according to the CSI-RS-Resource-Mobility configuration.

[0320] The embodiments of the present application are described only using the CSI-RS as a reference signal. In some embodiments, the above-mentioned reference signal sending and receiving schemes can also be applied to other types of reference signals, such as synchronization signals and physical broadcast channels (PBCH) blocks (Synchronization Signal and PBCH block, SSB), timing reference signals (TRS), etc.

[0321] To sum up, the embodiments of the present application provide a scheme for a terminal device to perform the behavior of receiving a reference signal when configured with N non-identical DRX cycle values, a first DRX time period including M second DRX time periods with non-identical durations, or a first DRX cycle with a duration of a non-integer value greater than zero. This scheme makes it possible for wireless communication behaviors such as receiving reference signals to be more applicable in the above three enhanced DRX modes, expands the DRX modes applicable to wireless transmission behaviors such as receiving reference signals, optimizes the wireless transmission process, and improves the data transmission efficiency under the DRX mechanism.

[0322] Please refer to Figure 14, which shows a block diagram of a wireless communication device provided by an embodiment of the present application. The wireless communication device has the functions of implementing the methods shown in Figures 7, 8, 9, 10, or 13 above, which are performed by the terminal device. As shown in Figure 14, the device may include:
