Alternatively, or in addition, the communication unit 220 may combine a transmitting unit and a receiving unit configured to transmit and receive signals, respectively, to a wireless terminal (e.g., user equipment or another wireless network node).

[0061] The following paragraphs will provide a detailed description with some examples, but the present disclosure is not limited to the following examples.

[0062] In some approaches, a gNodeB (gNB) may use network data transmission (DTX) / DRX with limitations based on the UE DRX configuration and configured transmission / reception, e.g., common channels / signals. Connected Mode Discontinuous Reception (C-DRX) may be configured per UE. Alignment of DRX cycles or offsets for different UEs may be done only via Radio Resource Control (RRC) signaling. During the DRX-off duration, the UE is not expected to monitor the physical downlink control channel (PDCCH), but can start uplink (UL) transmission according to configured resources (e.g., using a PUCCH or a random access channel (RACH), or a configured grant Physical Uplink Shared Channel (CG-PUSCH)).

[0063] Some embodiments of the present disclosure relate to cell DTX / DRX adaptation, which aims to provide the necessary signaling mechanism that allows a cell to remain inactive. Cell DTX / DRX may be configured by UE-specific RRC signaling. Some embodiments of the present disclosure may solve one or more of the following problems:

[0064] Challenge 1: How to ensure longer gNB sleep periods when DTX / DRX operation is configured? Challenge 2: How to trigger cell DTX / DRX activation / deactivation? Challenge 3: How to reduce the possibility of network congestion if data transmissions for all UEs camped on a cell are scheduled for the same DRX on duration? Problem 4: For one or more UEs that do not support cell DTX / DRX, how do they access a cell using cell DTX / DRX? In some embodiments, cell DTX / DRX adaptation may provide a signaling mechanism that allows a cell to remain inactive. This includes, for example, extending the UE DRX configuration to align or omit the DRX cycle or DRX start offset for UEs in connected or idle / inactive mode, potentially allowing longer opportunities for the cell to be inactive. During cell DTX / DRX, the cell may have no transmission / reception or may only have limited transmission / reception. For example, the cell does not need to transmit or receive some periodic signals / channels, such as common channels / signals or UE-specific signals / channels.

[0065] In some embodiments, the cell DTX / DRX on duration is the time duration when the cell DTX / DRX on duration timer is running.

[0066] In some embodiments, the 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.

[0067] In some embodiments, alignment of cell DTX / DRX and UE DRX means that the UE DRX on duration / active time falls within a certain time duration and / or the gap between the start positions of the UE DRX on duration / active time / cycle for the two UEs is less than or equal to a threshold value in the cell. In some embodiments, the threshold is an offset configured by RRC signaling or L1 signaling and / or a predetermined value, where the threshold is less than or equal to the value of the 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 less than or equal to 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 shows an example of alignment of cell DTX / DRX and UE DRX, where the UE DRX on duration is within the cell DTX on duration.

[0068] In some embodiments, if the UE is configured with UE DRX and cell DTX / DRX, the UE starts the UE DRX cycle / on duration timer after a UE DRX slot offset from the beginning of the 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, 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, at least one of the one or more parameters is configured by RRC signaling or L1 signaling.

[0069] In some embodiments, the subframe satisfies a function of at least one of the 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 at 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.

[0070] For example, the subframe (SFN) for 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, where the cell DTX / DRX on duration / cycle starts from the SFN. The offset for modifying the UE DRX start offset or slot offset is determined by (SFN + offset) mod T = 0, where T is the UE DRX on duration or UE DRX cycle or cell DTX / DRX on duration. In some embodiments, the new UE DRX start offset or slot offset is determined by a function of the offset and the original UE DRX start offset or slot offset, where the original UE DRX start offset or slot offset is the UE DRX start offset or slot offset in the last most recent UE DRX cycle or the UE DRX start offset or slot offset configured by RRC signaling. Here, the functions include addition, and / or multiplication, and / or subtraction, and / or division, and / or XOR, and / or modulo.

[0071] For example, the start 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 UE ID, the number of cell DTX / DRX on durations (e.g., cell DTX / DRX cycles or UE DRX cycles or UE DRX on durations) during the time duration (N0), the number of UE DRX on durations during the cell DTX / DRX on duration (N1), an index of one or a group of start times of the UE DRX on duration timer during the UE DRX on duration (i0), an index (opportunity) of a UE DRX on duration during 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 of one or a group of start times of the cell DTX / DRX on durations during the UE DRX on duration (i2), or an index of a cell DTX / DRX on duration during the cell DTX / DRX on duration (i2). For example, the starting slot / symbol / time index of the UE DRX on duration timer / cycle = ((UEID mod N1) × N2 + i2) mod N. The UE determines a new slot offset for the UE DRX on duration timer based on the starting slot / symbol / time index of the UE DRX on duration timer / cycle. The UE starts the UE DRX on duration timer after the new slot offset from the beginning of the SFN, where SFN is the subframe number where the cell DTX / DRX on duration / cycle starts.

[0072] In some embodiments, cell DTX / DRX may be considered as at least one of cell DTX and / or cell DRX for one or more base stations (BSs) and / or alignment of cell DTX / DRX with UE DRX.

[0210] In some embodiments, some specific fields of DCI Format 1-1 are used to indicate cell DTX / DRX indication information in response to at least one of the following conditions being met:

[0211] Condition-1: The CRC of DCI format 1_1 is scrambled by C-RNTI or MCS-C-RNTI. Condition-2: The One-Shot HARQ-ACK Request field is not present or has a value of '0'; Condition-3: The UE detects DCI format 1_1 in the primary cell that does not include a carrier indicator field or detects DCI format 1_1 in the primary cell that includes a carrier indicator field with a value equal to 0; Condition-4: resourceAllocation=resourceAllocationType0 and all bits of the frequency domain resource allocation field of DCI format 1_1 are equal to 0; Condition-5: resourceAllocation=resourceAllocationType1 and all bits in the frequency domain resource allocation field of DCI format 1_1 are equal to 1; Condition-6: resourceAllocation=dynamicSwitch and all bits in the frequency domain resource allocation field of DCI format 1_1 are equal to 0 or 1; Condition-7: The UE regards DCI format 1_1 as indicating SCell dormancy rather than scheduling PDSCH reception. In some embodiments, the specific fields of DCI format 1-1 include at least one of the following: - modulation and coding scheme of transport block 1, - New data indicator in transport block 1, - redundancy version of Transport Block 1, - HARQ process number, -Antenna port, or -DMRS sequence initialization.

[0212] In some embodiments, when the cell DTX / DRX indication information is triggered by L1 signaling, the DCI may indicate the cell DTX / DRX indication information by one or more fields. For example, the DCI may include at least one of DCI Format 0-0 and / or DCI Format 0-1 and / or DCI Format 0-2 and / or DCI Format 1-0 and / or DCI Format 1-1 and / or DCI Format 1-2 and / or DCI Format 3-0 and / or DCI Format 2-0 and / or DCI Format 2-1 and / or DCI Format 2-2 and / or DCI Format 2-3 and / or DCI Format 2-4 and / or DCI Format 2-5 and / or DCI Format 2-6 and / or DCI Format 2-7.

[0213] In some embodiments, when the cell DTX / DRX indication information is triggered by L1 signaling, a new DCI format is used to indicate the cell DTX / DRX indication information. In some embodiments, the new DCI format is new relative to any of the DCI formats in NR Rel-17. In some embodiments, the CRC of the new DCI format is scrambled by a new RNTI that is new relative to any of the DCI formats in NR Rel-17.

[0214] In some embodiments, two-level L1 signaling including a first DCI and a second DCI is used to indicate cell DTX / DRX indication information, where the first DCI indicates a first type of cell DTX / DRX indication information, and where the second DCI indicates a second type of cell DTX / DRX indication information. In some embodiments, the first type of cell DTX / DRX indication information includes at least one of the above cell DTX / DRX indication information, and the second type of cell DTX / DRX indication information indicates at least one of a UE DRX start offset, a slot offset, a UE DRX indication information, a cell DTX / DRX activation / deactivation value, or an offset for modifying the cell DTX / DRX indication information. In some embodiments, the UE monitors a PDCCH carrying the first DCI during a first time window and monitors a PDCCH carrying the second DCI during a second time window. wherein the first time window is located before or after the start of the cell DTX / DRX on duration, and the second time window is located before or after the end of the cell DTX / DRX on duration. In some embodiments, the first time window is during the cell DTX / DRX on duration or the cell DTX / DRX active time, and the second time window is during the cell DTX / DRX off duration or the cell DTX / DRX inactive time.

[0215] For example, the UE detects a first DCI during the cell DTX on duration, and the first DCI instructs activation / deactivation of the cell DTX pattern or start / stop of the cell DTX on duration. For example, the UE detects a second DCI after the cell DTX on duration or during the cell DTX off duration, and the second DCI instructs starting the UE DRX on duration timer based on an offset, where the offset is used to determine a new starting offset of the UE DRX on duration timer.

[0216] For example, the UE detects a first DCI during a cell DTX on duration, where the first DCI indicates deactivation of a cell DTX pattern or stopping of the cell DTX on duration. For example, the UE detects a second DCI after a cell DTX on duration or during a cell DTX off duration, where the second DCI indicates activation / deactivation of a cell DTX pattern or starting of the cell DTX on duration.

[0217] In some embodiments, when the cell DTX / DRX indication is triggered by L2 signaling, the MAC CE may indicate the cell DTX / DRX indication.

[0218] The bit field indicating the cell DTX / DRX indication information is determined according to at least one of the following methods: Method 1: One or more bits in a bit field used to indicate cell DTX and / or cell DRX indication information.

[0219] I. A bit field can be used to indicate cell DTX when the UE is provided by parameters related to cell DTX configured by higher layer parameters, and to indicate cell DRX when the UE is provided by parameters related to cell DRX configured by higher layer parameters. In some embodiments, a bit field does not indicate cell DTX and cell DRX together. A field in DCI formats 0-1 / 0-2 indicates cell DRX. A field in DCI formats 1-1 / 1-2 indicates cell DTX.

[0220] II. The first bit field is used to indicate cell DTX indication information, and the second bit field is used to indicate cell DRX indication information. In some embodiments, if the UE is not provided by parameters related to cell DTX configured by higher layer parameters, the first bit field is not present. In some embodiments, if the UE is not provided by parameters related to cell DRX configured by higher layer parameters, the second bit field is not present.

[0221] III. A first portion of the bits in the bit field is used to indicate cell DTX indication information, and a second portion of the bits in the bit field is used to indicate cell DRX indication information. In some embodiments, the first portion of the bits and the second portion of the bits do not overlap within the bit field.

[0222] Method 2: One or more trigger states of a bit field are used to indicate cell DTX / DRX indication information.

[0223] I. The number of bits (denoted as N) in the bit field is used to indicate the cell DTX / DRX indication information. In some embodiments, the number of trigger conditions (denoted as M) used to indicate the cell DTX / DRX indication information is less than or equal to 2N.

[0224] II. In some embodiments, a first trigger state is used to indicate at least one state of the cell DTX indication information, and a second trigger state is used to indicate at least one state of the cell DRX indication information. For example, N=2, and a trigger state of "00" is used to indicate cell DTX deactivation, "01" is used to indicate cell DTX activation, "10" is used to indicate cell DRX deactivation, and "11" is used to indicate cell DRX activation.

[0225] III. In some embodiments, the trigger state is used to indicate the state of at least one of the cell DTX indication information and the cell DRX indication information. For example, N=2, and a trigger state of "00" is used to indicate deactivation of cell DTX and cell DRX. For example, a trigger state of "01" is used to indicate activation of cell DTX and cell DRX. For example, trigger states of "10" and "11" are used to indicate activation and / or deactivation of cell DTX or cell DRX.

[0226] IV. In some embodiments, at least one of the trigger states can reinterpret the cell DTX / DRX indication information corresponding to another trigger state or can enable at least one of the remaining trigger states to indicate the cell DTX / DRX indication information. In some embodiments, a first trigger state indicates a first cell DTX / DRX indication information, and one or more of the remaining trigger states can indicate a second cell DTX / DRX indication information. In some embodiments, a third trigger state indicates a third cell DTX / DRX indication information, and one or more of the remaining trigger states can indicate a fourth cell DTX / DRX indication information, where the second and fourth cell DTX / DRX indication information indicate different values ​​of one of the cell DTX / DRX indication information. Here, the second and fourth cell DTX / DRX indication information indicate different types of cell DTX / DRX indication information. For example, trigger states with N=2 and N=4 are used for the cell DTX / DRX indication information. For example, after a DCI indicates cell DTX and cell DRX activation, trigger states of "00" and "01" are used to indicate cell DTX deactivation and cell DRX deactivation, respectively. For example, after a DCI indicates cell DTX and cell DRX deactivation, trigger states of "10" and "11" are used to indicate cell DTX activation and cell DRX activation, respectively.

[0227] Method 3: A bitmap of bit fields is used to indicate cell DTX / DRX indication information.

[0228] I. Each bit corresponds to one of the cell DTX / DRX indication information. II. Each bit corresponds to one type of cell DTX / DRX indication information.

[0229] III. Each bit corresponds to one state of the cell DTX / DRX indication information. IV. The first part of the bits is used to indicate cell DTX indication information, and the second part of the bits is used to indicate cell DRX indication information. For example, "1000" indicates cell DTX activation, and "0001" indicates cell DRX activation. For example, "1000" indicates cell DTX activation and cell DRX deactivation, and "0001" indicates cell DRX activation and cell DTX deactivation. For example, "1001" indicates cell DTX activation and cell DRX activation.

[0230] V. Each bit corresponds to one of the cell DTX / DRX indication information in a cell. VI. The first part of the bits is used to indicate cell DTX indication information in one or more cells, and the second part of the bits is used to indicate cell DRX indication information in one or more cells. In some embodiments, each two bits is used to indicate cell DTX and cell DRX indication information in one cell. For example, "1000" indicates cell DTX activation and cell DRX deactivation in the first cell and cell DTX and cell DRX deactivation in the second cell, and "0001" indicates cell DTX / DRX deactivation in the first cell and cell DTX deactivation and cell DRX activation in the second cell.

[0231] In some embodiments, the bit fields are used to indicate cell DTX and cell DRX indication information for FDD.

[0232] In some embodiments, two portions of the bits of the bitmap in the bit field are used to indicate cell DTX and cell DRX indication information for TDD, respectively.

[0233] According to one embodiment, for RRC connected mode UEs, to trade off reliability and energy saving performance, the signaling mechanism for cell DTX / DRX may include at least one of the following: At least one cell DTX / DRX group is configured for a group of UEs; At least one UE DRX indication information is configured for one or more UEs; In a CA scenario, if the UE detects a cell DTX / DRX indication on the PCell, the UE shall assume that the same cell DTX / DRX is used for the SCell supported by the UE.

[0234] Application of cell DTX / DRX indication information According to one embodiment, the UE applies the cell DTX / DRX indication with an application delay after receiving a PDCCH (eg, containing the cell DTX / DRX indication).

[0235] In some embodiments, the application delay is at least one of the following: Duration from after PDCCH reception to the beginning of the next cell DTX / DRX cycle or cell DTX / DRX on duration.

[0236] - Duration configured by higher layer parameters. Duration is in units of symbols / slots / subframes / frames / cell DTX cycles / cell DRX cycles.

[0237] The duration is determined based on the SCS configuration of the cell, the cell DTX / DRX cycle, the cell DTX / DRX and / or UE DRX start offset, offset, cell DTX / DRX on duration, UE DRX cycle, UE DRX on duration, HARQ-ACK information, the value of the minimum applicable scheduling offset K0 / K1 / K2, and / or the number of data retransmissions.

[0238] The duration value is determined by the product of values ​​configured by the SCS and / or higher layer parameters.

[0239] - The candidate values ​​for the applied delay are configured by higher layer parameters. The duration is 3 milliseconds after reporting of the HARQ-ACK information. In some embodiments, the HARQ-ACK information carries HARQ-ACK information of a MAC CE that indicates cell DTX / DRX indication information.

[0240] In some embodiments, if the UE receives a cell DTX / DRX activation indication provided by the cell DTX / DRX configured by higher layer parameters or by the MAC CE, the UE assumes that the cell DTX / DRX activation indication is valid 3 ms after reporting the HARQ-ACK information for the MAC CE.

[0241] In some embodiments, when the UE receives a cell DTX / DRX deactivation indication provided by cell DTX / DRX configured by higher layer parameters or by L1 signaling, the UE deactivates cell DTX / DRX and performs normal DL reception / UL transmission after an application delay. The delay is related to the SCS configuration of a group of cells, or a timer- or DCI-triggered BWP switching delay, or a minimum applicable scheduling offset indication application delay, or a PDCCH monitoring adaptation application delay. In some embodiments, the normal DL reception / UL transmission includes PDCCH monitoring, PDSCH reception, or PUCCH / PUSCH transmission, or common signal / channel reception.

[0242] In some embodiments, if the UE receives cell DTX / DRX activation information indicated by L1 signaling, the UE starts / applies the cell DTX / DRX operation from the slot after an application delay, or after PDSCH reception, or after successful PDSCH reception, or after successful PUCCH / PUSCH transmission, or at the start of the next cell DTX / DRX cycle, or at the start of the search time for DCI formats 2-6. The delay is related to the SCS configuration of the group of cells, or the timer or DCI triggered BWP switch delay, or the minimum applicable scheduling offset indication application delay, or the PDCCH monitoring adaptation application delay.

[0243] In some embodiments, the UE does not monitor the PDCCH during the application delay for applying the cell DTX / DRX indication information.

[0244] In some embodiments, the value of the applied delay is related to a subcarrier spacing (SCS) μ. The value of the applied delay is in units of symbols or slots or subframes or frames and is determined by a product of values ​​configured by the SCS and / or higher layer parameters. The candidate values ​​of the applied delay are configured by higher layer parameters. The minimum value of the applied delay is included in the candidate values ​​of the applied delay.

[0245] For example, Table 1 below provides an example of minimum values ​​of Applied Delay in symbols. In Table 1, the minimum value of Applied Delay 1 is used for BSs or UEs that require a larger delay value. Furthermore, the minimum value of Applied Delay 2 is used for BSs or UEs that support faster cell DTX / DRX operation switching capability.

[0246] [Table 1]

[0247] In some embodiments, the UE applies the instructions related to cell DTX / DRX operation at least at the beginning of the first symbol / slot / subframe / frame / cell DTX cycle / cell DTX on duration / cell DRX cycle / cell DRX on duration that is an applied delay after receiving the PDCCH.

[0248] FIG. 13 illustrates an example of a UE applying a cell DTX / DRX activation indication at the beginning of the next cell DRX / DTX cycle, according to one embodiment of the present disclosure.

[0249] FIG. 14 illustrates an example of a UE applying a cell DTX / DRX deactivation indication at the beginning of at least the first symbol / slot of the applied delay after receiving a PDCCH, according to one embodiment of the present disclosure.

[0250] In some embodiments, the UE applies the instructions related to cell DTX / DRX operation for the current cell DTX / DRX cycle.

[0251] In some embodiments, the UE applies the instructions related to cell DTX / DRX operation for the next n cell DTX / DRX cycles, where n may be an integer greater than or equal to 0, for example.

[0252] In some embodiments, the UE applies the indication related to cell DTX / DRX operation until receiving a PDCCH carrying updated / new indication related to cell DTX / DRX operation.

[0253] 15 illustrates an example of a UE applying a cell DTX / DRX deactivation indication for a current cell DTX / DRX cycle, according to one embodiment of the present disclosure. For example, normal behavior may indicate that the UE does not perform cell DTX / DRX operation, or that the UE performs UE DRX operation when UE DRX is configured.

[0254] Detection of DCI indicating cell DTX / DRX indication information According to one embodiment, the UE detects for a certain time window a PDCCH carrying an indication related to cell DTX / DRX.

[0255] FIG. 16 illustrates an example of a UE applying a cell DTX / DRX activation indication carried by a DCI detected during a time window, in accordance with one embodiment of the present disclosure.

[0261] In some embodiments, the first DCI carries indication information for a group of UEs or one UE, and / or the second DCI carries indication information for a group of UEs or one UE.

[0262] In some embodiments, the RNTI that scrambles the CRC of the first DCI is the same as the RNTI that scrambles the CRC of the second DCI. In some embodiments, the RNTI that scrambles the CRC of the first DCI is different from the RNTI that scrambles the CRC of the second DCI.

[0263] In some embodiments, the first indication information includes cell DTX / DRX indication information. In some embodiments, the second indication information includes cell DTX / DRX indication information, and / or UE DRX indication information, and / or a wake-up / non-wake-up indication, and / or an SCell dormant / non-dormant behavior indication, and / or a minimum applicable scheduling offset indicator.

[0264] In some embodiments, the UE detects a first DCI indicating the first indication information for a first time duration and / or detects a second DCI indicating the second indication information for a second time duration.

[0265] In some embodiments, the first instruction information is applied for a first time duration and / or the second instruction information is applied for a second time duration.

[0266] In some embodiments, the first time duration and / or the second time duration are opportunities or time durations. In some embodiments, the opportunities include at least one of PDCCH monitoring opportunities. In some embodiments, the PDCCH monitoring opportunities are used to detect DCI carrying cell DTX / DRX indication information.

[0267] In some embodiments, the first time duration and / or the second time duration are used to monitor a PDCCH carrying a second DCI.

[0268] In some embodiments, the next action is at least one of the following: 1-Performing cell DTX / DRX operation according to the first indication information.

[0269] 2-Performing cell DTX / DRX operation according to the second instruction information. 3- Performing UE DRX operation according to the second indication information.

[0270] 4- Ignore the first instruction. 5- Ignoring the secondary instruction information.

[0271] 6- Ignore the indication information associated with the cell DTX / DRX indication information. 7-Ignoring indication information associated with UE DRX operation.

[0272] In some embodiments, the UE performs the following actions when a specific event is met. The specific event may include at least one of the following: 1 - The first DCI and / or the second DCI is at least one of DCI format 0-1, DCI format 1-1, DCI format 0-2, DCI format 1-2, DCI format 2-6, and / or a new DCI format.

[0273] 2- The first DCI and / or the second DCI indicate cell DTX / DRX indication information and / or indication information associated with UE DRX operation.

[0274] 3- The interval between the detection times of the first DCI and the second DCI is less than or equal to the applied delay. 4 - The first time duration overlaps with the second time duration.

[0276] 6—The time interval between the first PDCCH opportunity for detecting the first DCI and the second PDCCH opportunity for detecting the second DCI is less than or equal to the applied delay.

[0277] 7- The value of the first indication information is different from the value of the second indication information. For example, the first indication information is used to disable the UE DRX active time timer duration and / or the second indication information is used to enable the UE DRX active time timer duration. For example, the second indication information is used to activate the cell DTX / DRX operation and / or the second indication information is used to deactivate the cell DTX / DRX operation.

[0279] In some embodiments, an indication of the cell DTX / DRX configuration has a higher priority than an indication associated with the UE CDRX configuration.

[0280] 18 illustrates an example in which a UE detects a first DCI indicating a first cell DTX / DRX indication used to deactivate or disable a timer duration of a UE DRX active time and a second DCI indicating a second wake-up indication for UE DRX, where the UE may perform a UE DRX operation according to the second wake-up indication and / or may ignore the first cell DTX / DRX indication, according to an embodiment of the present disclosure.
