[0235] In the following paragraphs, details will be described in conjunction with some examples, but the present disclosure is not limited to the following examples.

[0236] In some approaches, the gNB (gNodeB) may use network DTX (data transmission) / DRX with restrictions based on the UE DRX configuration and configured transmission / reception (e.g., common channels / signals). C-DRX (connected mode discontinuous reception) may be configured for each UE. Alignment of DRX cycles or offsets for different UEs can only be performed via RRC (radio resource control) signaling. During the DRX OFF duration, the UE is not expected to monitor the PDCCH (physical downlink control channel), but is allowed to initiate UL (uplink) transmissions based on the configured resources (e.g., using the PUCCH or RACH (random access channel), or CG-PUSCH (configured grant physical uplink shared channel)).

[0237] Some embodiments of the present disclosure relate to adaptation of cell DTX / DRX, with the goal of providing the necessary signaling mechanisms to enable a cell to remain deactivated. Cell DTX / DRX can be configured via UE-specific RRC signaling. In some embodiments of the present disclosure, one or more of the following issues can be addressed.

[0238] Question 1: How to ensure longer gNB sleep periods when DTX / DRX operation is configured?

[0239] Question 2: How to trigger cell DTX / DRX activation / deactivation?

[0240] Question 3: How to reduce the possibility of network congestion when data transmission of all UEs camped on a cell is scheduled on the same DRX ON DURATION?

[0241] Question 4: How can a UE or multiple UEs that do not support cell DTX / DRX access a cell with cell DTX / DRX?

[0242] In some embodiments, adaptation of cell DTX / DRX can provide a signaling mechanism that enables a cell to remain deactivated. This includes enhancements to UE DRX configuration, for example, to align or omit the DRX cycle or DRX start offset for UEs in connected mode or idle / deactivated mode, potentially allowing for longer periods of cell deactivation. During cell DTX / DRX, the cell may not transmit / receive, or may maintain only limited transmission / reception. For example, the cell may not need to transmit or receive certain periodic signals / channels, such as common channels / signals or UE-specific signals / channels.

[0243] In some implementations, the cell DTX / DRX ON DURATION is the duration that the cell DTX / DRX ON DURATION timer is running.

[0244] In some embodiments, cell DTX / DRX may indicate at least one of cell DTX and / or cell DRX and / or alignment of cell DTX / DRX with UE DRX.

[0245] In some embodiments, alignment of cell DTX / DRX with UE DRX means that the UE DRX ON DURATION / activation time falls within a duration, and / or the gap between the start positions of the UE DRX ON DURATION / activation time / cycle of two UEs is no greater than a threshold in the cell. In some embodiments, the threshold is an offset and / or a predefined value configured by RRC signaling or L1 signaling. The threshold is no greater than the value of a cell DTX / DRX parameter. In some embodiments, the cell DTX / DRX parameter includes at least one of cell DTX / DRX indication information. For example, the threshold is no greater than the value of the cell DTX / DRX ON DURATION or the DTX / DRX ON DURATION timer, and the start position of the UE DRX ON DURATION falls within the cell DTX / DRX ON DURATION configured or indicated by RRC signaling and / or L1 signaling. Figure 3 An example of alignment of cell DTX / DRX with UE DRX is shown, where the UE DRX ON DURATION falls within the cell DTX ON DURATION.

[0246] In some embodiments, when a UE is configured with UE DRX and cell DTX / DRX, the UE starts a UE DRX cycle / ON DURATION timer after a UE DRX slot offset from the start of a subframe. In some embodiments, the subframe, SFN, or UE DRX slot offset is determined by one or more parameters. In some embodiments, the one or more parameters include at least one of a UE ID, a UE DRX slot offset, a UE DRX start offset, a UE DRX short cycle, a UE DRX long cycle, an SFN, a UE DRX ON DURATION timer, a cell DTX / DRX start offset, a cell DTX / DRX slot offset, a cell DTX / DRX cycle, a cell DTX / DRX ON DURATION, or an offset. In some embodiments, at least one of the one or more parameters is configured by RRC signaling or L1 signaling.

[0247] In some embodiments, a subframe satisfies a function of at least one of parameters. In some embodiments, the one or more parameters include at least one of a UE ID, a UE DRX slot offset, a UE DRX start offset, a UE DRX short cycle, a UE DRX long cycle, a SFN, a UE DRX on duration timer, a cell DTX / DRX start offset, a cell DTX / DRX slot offset, a cell DTX / DRX cycle, a cell DTX / DRX on duration, or an offset. In some embodiments, the SFN is the subframe number from which at least one of the UE DRX on duration timer / cycle or the cell DTX / DRX cycle / on duration timer starts. In some embodiments, the offset is used to modify at least one of the UE DRX slot offset, the UE DRX start offset, the cell DTX / DRX start offset, or the cell DTX / DRX slot offset.

[0248] For example, the subframe at the start of the cell DTX / DRX on duration / cycle (denoted as dtx-Start) is determined by [(SFN×10)+subframe number] modulo(cell DTX / DRX cycle)=cell DTX / DRX slot offset. The cell DTX / DRX on duration / cycle starts from the SFN. The offset used to modify the UE DRX start offset or slot offset is determined by (SFN+offset) mod T=0. T is the UE DRX on duration or UE DRX cycle or cell DTX / DRX on duration. In some embodiments, a new UE DRX start offset or slot offset is determined by a function of the offset and an original UE DRX start offset or slot offset. The original UE DRX start offset or slot offset is the UE DRX start offset or slot offset in the most recent UE DRX cycle or the UE DRX start offset or slot offset configured by RRC signaling. The function includes addition, and / or multiplication, and / or subtraction, and / or division, and / or XOR (exclusive OR), and / or modulo.

[0249] For example, the starting slot / symbol / time of the UE DRX ON DURATION timer / cycle during the cell DTX / DRX ON DURATION is further determined by at least one of the following: UE ID, the number of cell DTX / DRX ON DURATIONs in a duration (e.g., cell DTX / DRX cycle or UE DRX cycle or UE DRX ON DURATION) (N0), the number of UE DRX ON DURATIONs during the cell DTX / DRX ON DURATION (N1), an index (i0) of one or a group of start times of the UE DRX ON DURATION timer in the UE DTX / DRX ON DURATION, an index (of timing) of the UE DRX ON DURATION in the cell DTX / DRX ON DURATION (i1), an indication of the number of availability of start times of the UE DRX ON DURATION timer (N3), an index (i2) of one or a group of start times of the cell DTX / DRX ON DURATION in the UE DRX ON DURATION, an index (i2) of the cell DTX / DRX ON DURATION in the cell DTX / DRX ON DURATION. For example, the index of the starting slot / symbol / time of the UE DRX ON DURATION timer / cycle = ((UEID mod N1) × N2 + i2) mod N. The UE determines the new slot offset of the UE DRX ON DURATION timer based on the index of the starting slot / symbol / time of the UE DRX ON DURATION timer / cycle. The UE starts the UE DRX ON DURATION timer after the new slot offset from the start of SFN. Where SFN is the subframe number of the cell DTX / DRX ON DURATION / cycle.

[0250] In some embodiments, cell DTX / DRX may be considered as at least one of cell DTX and / or cell DRX and / or alignment of cell DTX / DRX with UE DRX for one or more base stations (BSs).

[0251] In some embodiments, the cell DTX / DRX OFF DURATION includes at least one of a cell DTX / DRX deactivation period, a cell DTX / DRX out-activation time, outside the cell DTX / DRX activation time, outside the cell DTX / DRX ON DURATION in the cell DTX / DRX periodicity / cycle, and outside the UE DRX activation time.

[0472] For example, the configuration information of cell DTX and UE DRX may include at least one of the following: an offset; one or more configuration sets of cell DTX and UE DRX (wherein the configuration information of "one or more configuration sets of cell DTX and UE DRX" includes at least one of the above parameters of cell DTX and UE DRX and / or set indexes / identifiers of one or more configuration sets); and / or a set of candidate values ​​for at least one parameter in the configuration sets of cell DTX and UE DRX.

[0473] In some embodiments, the offset is: a start offset for determining the start of a cell DTX cycle and a UE DRX cycle; and / or an offset for determining the start of a cell DTX-on duration, or a cell DTX activation time, and / or a UE DRX cycle, or a UE DRX-on duration, or a UE DRX activation time; and / or an offset for determining the length of a time interval between the start of a cell DTX cycle and a UE DRX cycle, or the interval between the start of a cell DTX-on duration and a UE DRX-on duration, and / or a start offset of a UE DRX-on duration or a UE DRX cycle. In some embodiments, the offset is the minimum gap between two start positions of a UE DRX-on duration / cycle for UEs in a cell or cell group. In some embodiments, the offset is no greater than a UE DRX-on duration timer or a cell DTX / DRX-on duration timer.

[0474] In some embodiments, the configuration set of cell DTX and UE DRX includes at least one of the following parameters: a set ID, a start offset, a cell DTX period and / or a UE DRX period, a cell DTX on duration and / or a UE DRX on duration, a cell DTX off duration and / or a UE DRX off duration, a cell DTX deactivation timer and / or a UE DRX deactivation timer. The start offset includes at least one of a start offset of a cell DTX period / a UE DRX period and / or a start offset of a cell DTX on duration / a UE DRX on duration.

[0475] In some embodiments, the configuration set of cell DTX and UE DRX includes at least one candidate value for at least one parameter in the configuration set of cell DTX and UE DRX.

[0476] In some implementations, the candidate value of at least one parameter in the configuration sets for cell DTX and UE DRX is the same.

[0477] In some implementations, the candidate value of at least one parameter in the cell DTX configuration set and the UE DRX configuration set is the same.

[0478] In some embodiments, the parameters of the configuration set for cell DTX include at least one parameter of the configuration for cell DRX, and vice versa.

[0479] In some embodiments, at least one parameter of the configuration set is used for both cell DTX and UE DRX. In some embodiments, the at least one parameter includes: a start offset, and / or a period of cell DTX and / or UE DRX, and / or an ON duration of cell DTX and / or UE DRX.

[0480] The value of the parameter of the cell DTX / DRX configuration information

[0481] According to an embodiment of the present invention, the value of the cell DTX / DRX parameter is related to the value of the UE DRX parameter.

[0482] In some embodiments, at least one parameter of the cell DTX / DRX is configured to be the same value as a UE DRX parameter.

[0483] In some embodiments, the value of the cell DTX / DRX cycle or DTX / DRX ON DURATION or cell DTX / DRX OFF DURATION is configured as a multiple of the value of the UE DRX parameter, or the value of the UE DRX parameter is divisible by the value of the cell DTX / DRX cycle or DTX / DRX ON DURATION or cell DTX / DRX OFF DURATION.

[0484] In some implementations, the value of the cell DTX / DRX ON DURATION timer or the length of the cell DTX / DRX ON DURATION is equal to the value of the cell DTX / DRX periodicity or the cell DTX / DRX cycle.

[0485] In some implementations, the value of the cell DTX / DRX ON DURATION timer or the length of the cell DTX / DRX OFF DURATION is equal to the value of the cell DTX / DRX periodicity or the cell DTX / DRX cycle.

[0486] In some embodiments, the value of the cell DTX / DRX cycle or DTX / DRX ON DURATION or cell DTX / DRX OFF DURATION is not less than 2 ms or not greater than the product of n and 10240 ms, where n is an integer not less than 1.

[0487] In some embodiments, the value of the cell DTX / DRX cycle or DTX / DRX ON DURATION or cell DTX / DRX OFF DURATION is δ×2 mAn integer of the form δ, where δ is at least one of the following: 1, 3, 5, 7, 15, and 35, and m is an integer not less than 0 and not greater than 20. In some embodiments, the value of the cell DTX / DRX cycle, DTX / DRX ON DURATION, or cell DTX / DRX OFF DURATION is in symbols, slots, or milliseconds. For example, if the UE long DRX cycle is set to 60 ms, the cell DTX / DRX cycle can be set to 120 ms, 180 ms, or 300 ms, etc. For example, if the UE long DRX cycle is set to 10240 ms, the cell DTX / DRX cycle can be set to 5120 ms or 2048 ms. If the UE long DRX cycle is divisible by the cell DTX / DRX cycle, or if the cell DTX / DRX cycle is set to 20480 ms, 40960 ms, or 51200 ms (a multiple of the UE DRX cycle), the cell DTX / DRX cycle is an integer multiple of the UE long DRX cycle.

[0488] In some embodiments, the value of the cell DTX / DRX cycle or the DTX / DRX ON DURATION or the cell DTX / DRX OFF DURATION is n (in units of 1 / 32 milliseconds), where n is a positive integer not greater than 31. For example, the value of the cell DTX / DRX cycle is 7, indicating that the cell DTX / DRX cycle is 7 / 32 milliseconds.

[0489] In some embodiments, candidate values ​​for the cell DTX / DRX cycle and / or the cell DTX / DRX ON duration and / or the cell DTX / DRX OFF duration include at least one of candidate values ​​for the UE long DRX cycle and / or the UE short DRX cycle. For example, candidate values ​​for the cell DTX / DRX cycle and / or the cell DTX / DRX ON duration and / or the cell DTX / DRX OFF duration include at least one of {2, 3, 4, 5, 6, 7, 8, 10, 14, 16, 20, 30, 32, 35, 40, 60, 64, 70, 80, 128, 160, 256, 320, 512, 640, 1024, 1280, 2048, 2560, 5120, 10240}; wherein the candidate values ​​are in milliseconds or time slots.

[0490] In view of the above, appropriate cell DTX / DRX OFF DURATION can be enabled to enable the network to achieve energy saving benefits.

[0491] In some embodiments, the UE DRX parameters include at least one of the following: DRX ON DURATION timer; DRX deactivation timer; DRX HARQ RTT timer; DRX retransmission timer; DRX long cycle; DRX short cycle; a multiple of the DRX short cycle and the DRX short cycle timer; the start of the search time for wake-up signal / DCI format 2-6; and the search time for wake-up signal / DCI format 2-6.

[0492] In some embodiments, the start offset of the cell DTX / DRX cycle is related to or determined by at least one of the following UE DRX parameters: DRX long cycle or DRX short cycle; offset of DRX long cycle or DRX short cycle; PS offset of search time for DCI formats 2-6.

[0493] According to an embodiment of the present invention, during a cell DTX / DRX cycle, different values ​​of the offset of the DRX cycle or the DRX ON DURATION timer or the DRX deactivation timer are allowed for different cell groups, or for different cells, or for different UE groups, or for different UEs.

[0494] According to an embodiment of the present invention, the values ​​of the cell DTX parameters are the same as the values ​​of the cell DRX parameters. These parameters may include at least one of a set ID, an offset, a start offset, a cell DTX and / or cell DRX cycle, a cell DTX and / or cell DRX on duration, a cell DTX and / or cell DRX off duration, and a cell DTX and / or cell DRX deactivation timer.

[0495] In some embodiments, the start offset includes at least one of a start offset of a DTX / DRX cycle and / or a start offset of a DTX / DRX ONDURATION.

[0496] In some embodiments, when the offset is used to determine the length of the time interval between the start of the cell DTX cycle and the cell DRX cycle, or the interval between the start of the cell DTX ON DURATION and the cell DRX ON DURATION, the value of the offset is no greater than the length of the cell DTX ON DURATION and / or the length of the cell DTX cycle and / or the length of the cell DRX ON DURATION.

[0497] In some implementations, the candidate value of at least one parameter in the configuration sets of cell DTX and cell DRX is the same.

[0498] In some implementations, candidate values ​​of at least one parameter in the cell DTX configuration set and the cell DRX configuration set are the same.

[0499] UE behavior

[0500] This section concerns UE behavior related to cell DTX / DRX, UE DRX and CSI reporting when the UE supports the UE feature of cell DTX / DRX.

[0501] According to an embodiment of the present invention, if the UE is provided with cell DTX / DRX configuration information, and / or the cell DTX / DRX configuration information satisfies a predefined condition for the first cell and the second cell, the UE may perform the next action.

[0502] In some embodiments, the first cell is a primary cell and the second cell is a secondary cell; and / or the first cell is a secondary cell and the second cell is another secondary cell; and / or the first cell is a scheduling cell and the second cell is a scheduled cell; and / or the first cell and the second cell are the same cell; and / or the first cell is a PScell ​​and the second cell is a secondary cell; and / or the first cell is a Pcell and the second cell is a PScell.

[0503] In some embodiments, the predefined condition is at least one of the following: at least one value of the cell DTX / DRX configuration information is different for the first cell and the second cell; the value of the cell DTX / DRX configuration information of the first cell is less than that of the second cell; the value of the cell DTX / DRX configuration information of the first cell is greater than that of the second cell; the value of the cell DTX / DRX configuration information of the first cell is equal to that of the second cell; the number of parameters related to cell DTX / DRX of the first cell is less than or greater than or equal to that of the second cell; cell DTX / DRX activation is applied on the first cell and cell DTX / DRX deactivation is applied on the second cell; cell DTX / DRX deactivation is applied on the first cell and cell DTX / DRX activation is applied on the second cell; the first cell is during the cell DTX / DRX ON DURATION / activation time and the second cell is during the cell DTX / DRX OFF DURATION / activation out time; the first cell is during the cell DTX / DRX OFF DURATION / activation out time and the second cell is during the cell DTX / DRX ON DURATION / activation time period; parameters of the cell DTX / DRX configuration information on the first cell are different from or not aligned with parameters of the cell DTX / DRX configuration information.

[0504] In some embodiments, the next action is at least one of the following: the UE does not perform cell DTX / DRX operation on the second cell according to the cell DTX / DRX configuration information; the UE does not perform cell DTX / DRX operation on the first cell according to the cell DXT / DRX configuration information; the UE does not perform cell DTX / DRX operation on the first cell and the second cell according to the cell DXT / DRX configuration information; the UE performs cell DTX / DRX operation on the first cell according to the cell DTX / DRX configuration information of the first cell; the UE performs cell DTX / DRX operation on the second cell according to the cell DXT / DRX configuration information of the first cell; the UE performs cell DTX / DRX operation on the first cell and the second cell according to the cell DXT / DRX configuration information of the first cell.

[0505] In some embodiments, if the UE is provided with different cell DTX / DRX configuration information for the PCell and the SCell, the UE may not perform cell DTX / DRX operation on the second cell according to the cell DTX / DRX configuration information.

[0506] In some embodiments, the cell DTX / DRX cycle on the first cell is greater than or equal to the cell DTX / DRX cycle on the second cell.

[0507] In some embodiments, the cell DTX / DRX ON DURATION on the first cell is greater than or equal to the cell DTX / DRX ON DURATION on the second cell.

[0508] According to an embodiment of the present invention, for carrier aggregation (CA), at least one of the following events occurs: for cross-carrier scheduling, the second cell is not provided through the cell DTX / DRX configuration; for cross-carrier scheduling, the first cell is not provided through the cell DTX / DRX configuration; the detection of DCI formats 2-6, and / or Scell ​​sleep / non-sleep behavior indication, and / or UE DRX group configuration is not supported by the first cell and / or the second cell or is suspended; at least one parameter related to the UE DRX configuration on the first cell and / or the second cell is not aligned or does not need to be set to the same value; the start offset and / or period and / or ON DURATION of the cell DTX / DRX configuration on the first cell is greater than or equal to the start offset and / or period and / or ON DURATION of the cell DTX / DRX configuration on the second cell.

[0509] In some embodiments, the first cell is a primary cell and the second cell is a secondary cell; and / or the first cell is a secondary cell and the second cell is another secondary cell; and / or the first cell is a scheduling cell and the second cell is a scheduled cell; and / or the first cell and the second cell are the same cell; and / or the first cell is a PScell ​​and the second cell is a secondary cell; and / or the first cell is a Pcell and the second cell is a PScell.

[0510] In some embodiments, for a UE configured with CA, the UE DRX configuration information and / or the cell DTX / DRX configuration information of the first cell and the second cell may be the same.

[0511] In some implementations, for a UE configured with CA, DCI formats 2-6 and cell DTX / DRX configuration information may not be configured together.

[0512] According to an embodiment of the present disclosure, if the UE detects that the DCI schedules data in the first cell that can be sent during the cell DTX / DRXOFF DURATION on the second cell, the UE may perform at least one of the following actions: the UE receives or sends data according to the scheduling information; the UE receives or sends data during the cell DTX / DRX ON DURATION and / or activation time in the next cell DTX / DRX cycle according to the scheduling information; the UE assumes that the data scheduling information is invalid; the data scheduling information is ignored by the UE or is not expected by the UE; and / or the UE sends a request for cell DTX / DRX configuration on the scheduled cell or SCell.

[0513] In view of the above, it can be ensured that the UE sends / receives scheduled data as quickly as possible.

[0514] For example, if the UE is configured with deactivated cell DTX / DRX function in PCell and the UE is configured with cell DTX / DRX mode in SCell, when the UE detects PDCCH in PCell carrying cross-carrier scheduling information of data sent / received in SCell and SCell is the scheduled cell, the UE ignores the cross-carrier scheduling information.

[0515] For example, if the UE is configured with cell DTX / DRX mode in both PCell and SCell and the start or end or length of the cell DTX / DRX ON DURATION are not aligned for PCell and SCell, when the UE needs to perform periodic CSI measurement / reporting in PCell to achieve synchronization of only UL SCell at time slot n, the UE assumes that the cell DTX / DRX activation time is extended to time slot n in PCell, where the time slot is during the cell DTX / DRX deactivation period of PCell and during the cell DTX / DRX activation time of SCell.

[0516] Figure 13 An example of data scheduling information on a PCell according to an embodiment of the present disclosure is shown, where the data scheduling information indicates data reception for a UE during a cell DTX OFF DURATION on an SCell. Thereafter, the UE receives a PDSCH during the cell DTX OFF DURATION on the SCell according to the data scheduling information.

[0517] According to an embodiment of the present invention, if the UE is provided with cell DTX / DRX configuration information, when a predefined condition is met, the UE performs the next action related to CSI reporting.

[0518] In some embodiments, the predefined condition may be at least one of the following: the UE is configured by a higher layer parameter; the UE is configured to report a specific number of CSI reports; the most recent CSI measurement opportunity occurs within a duration associated with the cell DTX / DRX cycle, and / or cell DTX / DRX ON DURATION, and / or cell DTX / DRX OFF DURATION, and / or UE DRX cycle, and / or UE DRX ON DURATION timer of the CSI to be reported; the UE receives at least one CSI-RS transmission opportunity for channel measurement and / or CSI-IM opportunity for CSI-RS for interference measurement during a duration no later than the CSI reference resource; the UE receives at least one CSI-RS transmission opportunity for each CSI-RS resource in a resource pair during a duration no later than the CSI reference resource; the UE receives at least one CSI-RS transmission opportunity for channel measurement during a duration no later than the CSI reference resource; the UE is configured by a higher layer parameter to report L1-RSRP (e.g., the UE is configured by a higher layer parameter ps-TransmitPeriod). odicL1-RSRP is configured to report L1-RSRP); CSI reporting is set to "periodic" or "semi-persistent" (e.g., the UE is configured by a higher layer parameter reportConfigType set to "periodic"); the UE is configured by a higher layer parameter reportQuantity configured to a specific quantity; the UE is configured to listen to DCI formats 2-6; the DRX cycle in use is greater than 80 ms; the UE detects a DCI format 2-6 indicating "no wake-up indication"; drx-onDurationTimer is not started; the UE is configured with cell DTX; the UE is configured with cell DRX; the UE is configured to send SRS.

[0526] In some embodiments, the UE does not need to perform measurements based on CSI-RS-Resource-Mobility except during the timer duration associated with the cell DTX / DRX cycle, and / or cell DTX / DRX ON DURATION, and / or cell DTX / DRX OFF DURATION, and / or UE DRX cycle, and / or UE DRX ON DURATION timer.

[0527] In some embodiments, these specific quantities include at least one of the following: any one of the CSI reporting quantities; CSI with the "periodic" type and set to a quantity other than "cri-RSRP" and "ssb-Index-RSRP"; L1-RSRP with the "periodic" type and set to cri-RSRP; "cri-RSRP"; "ssb-Index-RSRP"; "cri-RSRP-Capability[Set]Index"; "ssb-Index-RSRP-Capability[Set]Index".

[0528] In some embodiments, the duration associated with the cell DTX / DRX cycle, and / or the cell DTX / DRX ON DURATION, and / or the cell DTX / DRX OFF DURATION, and / or the UE DRX cycle, and / or the UE DRX ON DURATION timer is at least one of the following durations:

[0549] 21-Cell DTX / DRX ON DURATION and / or cell DTX / DRX ON DURATION within the timer duration outside the UE DRX ON DURATION;

[0550] 22-Cell DTX / DRX out-of-activation time and / or cell DTX / DRX OFF DURATION within the timer duration outside the UE DRX activation time.

[0551] In some embodiments, for example, if the UE is configured to monitor DCI indicating information related to cell DTX / DRX, and is configured by higher layer parameters to report a specific number of CSI (channel state information) reports when the DTX OFF DURATION overlaps with the UE DRX activation time, then the most recent CSI measurement opportunity occurs within the duration of the UE DRX activation time that overlaps with the DTX OFF DURATION of the reported CSI. In some embodiments, the CSI report is CSI, or RSRQ (reference signal received quality), or RSSI (received signal strength indicator), or L1-RSRP (layer 1 reference signal received power).

[0552] In some implementations, for the CSI-RS (Channel State Information Reference Signal) reception process, if the UE is configured with cell DTX / DRX, the UE may perform the following operations:

[0553] - If the UE is configured to listen for information indicating cell DTX / DRX and is configured by one or more higher layer parameters to report DCI with type "periodic" and set to a quantity of CSI other than "cri-RSRP" and "ssb-Index-RSRP" when the DTX OFF DURATION overlaps with the UE DRX activation time, then the nearest CSI measurement opportunity occurs within the duration of the UE DRX activation time that overlaps with the DTX OFF DURATION of the reported CSI;

[0554] - if the UE is configured to listen for information indicating cell DTX / DRX and is configured by one or more higher layer parameters to report DCI with type "periodic" and LI-RSRP set to cri-RSRP when the DTX OFF DURATION overlaps with the UE DRX activation time, then the nearest CSI measurement opportunity occurs within the duration of the UE DRX activation time that overlaps with the DTX OFF DURATION of the reported CSI;

[0555] - Otherwise, the latest CSI measurement opportunity occurs within the DTX ON DURATION of the reported CSI.

[0556] In some embodiments, as another example, if the UE is configured with cell DTX / DRX, or when the UE is configured to monitor DCI indicating information related to cell DTX / DRX, or when the DTX period or DTX-ON duration or DTX-OFF duration is greater than T, the UE may perform measurements and / or report CSI reports during the DTX-ON duration or during the duration of the UE DRX activation time overlapping with the DTX-OFF duration. In some embodiments, T is not less than 80 ms. In some embodiments, the CSI report is CSI, or RSRQ, or RSSI, or L1-RSRP.

[0557] In some embodiments, for CSI-RS for mobility, if the UE is configured with cell DTX / DRX, the UE does not need to perform measurements of CSI-RS resources except during the DTX ON DURATION period based on CSI-RS-Resource-Mobility measurements. When the UE is configured to monitor DCI indicating information related to cell DTX / DRX, the UE does not need to perform measurements except during the DTX ON DURATION period based on CSI-RS-Resource-Mobility and the duration of DTX OFFDURATION that overlaps with the UE DRX activation time.

[0558] In some embodiments, if the UE is configured with cell DTX / DRX and the used DTX period or DTX ON Duration is greater than 80 ms, the UE may expect that the CSI-RS resources are unavailable except during the DTX ON Duration or UE DRX activation time for CSI-RS-Resource-Mobility based measurements or during the duration of the UE DTX activation time overlapping with the UE DRX OFF Duration. If the UE is configured with cell DTX / DRX and is configured to listen to DCI indicating information related to cell DTX / DRX and the used DTX period or DTX ON Duration is greater than 80 ms, the UE may expect that the CSI-RS resources are unavailable except during the DTX ON Duration or UE DRX activation time for CSI-RS-Resource-Mobility based measurements or during the duration of the UE DTX activation time overlapping with the UE DRX OFF Duration. Otherwise, the UE may assume that the CSI-RS is available for CSI-RS-Resource-Mobility based measurements.

[0559] In some embodiments, when cell DTX / DRX is configured, the UE reports a CSI report only when at least one CSI-RS transmission opportunity for channel measurement and a CSI-RS and / or CSI-IM opportunity for interference measurement is received within the DTXON DURATION no later than the CSI reference resource, otherwise the report is discarded.

[0560] In some embodiments, when cell DTX / DRX is configured and the CSI-RS resource set for channel measurement corresponding to the CSI report is configured with two resource groups and N resource pairs, the UE reports the CSI report only when at least one CSI-RS transmission opportunity for each CSI-RS resource in the resource pair is received within the same DTX ON DURATION no later than the CSI reference resource, otherwise the report is discarded.

[0561] In some embodiments, when the UE is configured to listen to DCI indicating information related to cell DTX / DRX and if the UE is configured by the higher layer parameter ps-TransmitOtherPeriodicCSI to report CSI with the higher layer parameter reportConfigType set to "periodic" and the higher layer parameter reportQuantity set to a quantity other than "cri-RSRP", "ssb-Index-RSRP", "cri-RSRP-Capability[Set]Index" and "ssb-Index-RSRP-Capability[Set]Index", when drx-onDurationTimer is not started, if at least one CSI-RS transmission opportunity for channel measurement and CSI-RS and / or CSI-IM opportunity for interference measurement is received during the duration of the UE DRX activation time overlapping with the DTX OFF DURATION or within the UE DRX activation time or within the DTX ON DURATION no later than the CSI reference resource, the UE may report CSI during the duration of the UE DRX activation time overlapping with the DTX OFF DURATION, otherwise discard the reporting.

[0562] In some embodiments, when the UE is configured to listen to DCI indicating information related to cell DTX / DRX and if the UE is configured by the higher layer parameter ps-TransmitPeriodicL1-RSRP to report L1-RSRP with the higher layer parameter reportConfigType set to “periodic” and the higher layer parameter reportQuantity set to “cri-RSRP”, “ssb-Index-RSRP”, “cri-RSRP-Capability[Set]Index” or “ssb-Index-RSRP-Capability[Set]Index” when the UE DRX activation time overlaps with the DTX OFF DURATION, if at least one CSI-RS transmission opportunity for channel measurement is received during the duration of the UE DRX activation time overlapping with the DTX OFF DURATION or within the UE DRX activation time or within the DTX ON DURATION of the CSI reference resources not later than the CSI-RS transmission opportunity for channel measurement, the UE DRX activation time overlapping with the DTX OFF DURATION may be reported. During the duration of the DRX activation time and when reportQuantity is set to "cri-RSRP" or "cri-RSRP-Capability[Set]Index", the UE may report L1-RSRP, otherwise the report is discarded.

[0563] In some embodiments, DRX is a function that controls the UE's activation of PDCCH monitoring of C-RNTI, CI-RNTI (Cancellation Indication RNTI), CS-RNTI, INT-RNTI (Interruption RNTI), SFI-RNTI (Slot Format Indication RNTI), SP-CSI-RNTI (Semi-Persistent CSI RNTI), TPC-PUCCH-RNTI (Transmit Power Control-PUCCH-RNTI), TPC-PUSCH-RNTI (Transmit Power Control-PUSCH-RNTI), TPC-SRS-RNTI (Transmit Power Control-Sounding Reference Symbol-RNTI), AI-RNTI (Availability Indication RNTI), SL-RNTI (Sidelink RNTI), SLCS-RNTI (Sidelink Configured Scheduling RNTI), and SL (Sidelink) Semi-Persistent Scheduling V-RNTI of the MAC (Medium Access Control) entity. When DRX operation is used, the MAC entity may also monitor the PDCCH as needed. When in RRC_CONNECTED, if DRX is configured, the MAC entity may monitor the PDCCH discontinuously using DRX operation for all activated serving cells; otherwise, the MAC entity may monitor the PDCCH in a different manner.

[0564] In some embodiments, the serving cells of the MAC entity may be configured by RRC in two DRX groups with separate DRX parameters. When RRC does not configure a secondary DRX group, there is only one DRX group and all serving cells belong to this one DRX group. When two DRX groups are configured, each serving cell will be uniquely assigned to either of the two groups. The DRX parameters configured separately for each DRX group may be: drx-onDurationTimer and drx-InactivityTimer. The DRX parameters common to the DRX group may be: drx-SlotOffset, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, drx-LongCycleStartOffset, drx-ShortCycle (optional), drx-ShortCycleTimer (optional), drx-HARQ-RTT-TimerDL, drx-HARQ-RTT-TimerUL and uplinkHARQ-Mode (optional).

[0565] In some implementations, a DRX group indicates a group of serving cells configured by RRC and having the same DRX activation time.

[0566] When DRX is configured, the activation time of the serving cell in the DRX group includes the following times:

[0567] - The drx-onDurationTimer or drx-InactivityTimer configured for the DRX group is running; or

[0568] - drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, or drx-RetransmissionTimerSL is running on any serving cell in the DRX group; or

[0569] -ra-ContentionResolutionTimer or msgB-ResponseWindow is running; or

[0570] - a Scheduling Request is sent on the PUCCH and is pending; if the serving cell belongs to a non-terrestrial network, the activation time starts after the first Scheduling Request is sent plus the UE-gNB RTT; or

[0571] -After successfully receiving a random access response for a random access preamble not selected by the MAC entity among contention-based random access preambles, a newly transmitted PDCCH indicating a C-RNTI addressed to the MAC entity has not been received.

[0572] According to an embodiment of the present invention, the adaptation of the DL common signal and the broadcast signal and the joint configuration of the DTX / DRX operation may be performed as follows:

[0573] - For connected mode UEs: configure cell DRX / DTX during outside of DTX / DRX activation time and perform SSB / SIB1 cell free.

[0574] - For idle mode UEs: configure cell DRX / DTX during periods other than DTX / DRX activation time and configure simplified SSB or SSB with greater periodicity.

[0575] Figure 14 An example of cell DTX / DRX according to an embodiment of the present disclosure is shown. Figure 14 As shown in , part of the DRX active time of UE3 can be deactivated based on the DTX off period.

[0576] By utilizing the configuration of at least one of the above embodiments, a longer dormant period of the gNB can be ensured. For legacy UEs or UEs that do not support DTX / DRX operation, this can also assist the UE in accessing cells with cell DTX / DRX.

[0577] In some embodiments, during periods outside of the DRX activation time, SSB / SIB transmission configured by RRC signaling is stopped, and / or adaptation of SSB / SIB transmission configured / indicated for one or more UEs is stopped.

[0578] In some embodiments, adaptation of DL common and broadcast signals may be triggered by the end / stop / expiry of the DRX ON DURATION timer, the end / stop of the DRX deactivation timer, the end / stop / expiry of the DRX RTT timer / DRX retransmission timer, the end of the DRX activation time, or the start outside the DRX activation time.

[0579] According to an embodiment of the present disclosure, a wireless communication method is also provided. In an embodiment, the wireless communication method can be performed by using a wireless communication terminal (e.g., UE). In an embodiment, the wireless communication terminal can be implemented by using the wireless communication terminal 40 described above, but is not limited thereto.
