Description

Technical Field

[0001] This document generally deals with wireless communication, especially 5G communication. Background Technology

[0002] Discontinuous reception (DRX) is an energy-saving technology. The basic mechanism of DRX is to configure a DRX cycle for the UE (user equipment), where a DRX cycle begins with a `drx-onDurationTimer` (DRX active duration timer). During the `drx-onDurationTimer`, the UE is in a DRX active (On) state and continuously monitors the physical downlink control channel (PDCCH). If the UE successfully decodes the PDCCH, it remains awake (i.e., in a DRX active state) and starts an inactivity timer. After either the `drx-onDurationTimer` or the `drx-inactivityTimer` (DRX inactivity timer) expires, the UE can enter sleep mode (i.e., in a DRX off state). Figure 1 (The opportunity for DRX is shown in the diagram). When DRX is off, the UE does not monitor the PDCCH.

[0003] DRX activation or UE keep-awake means that the UE is in an active state. When DRX is configured, the active state for the serving cell in the DRX group includes the following conditions:

[0004] - The drx-onDurationTimer or drx-InactivityTimer configured for the DRX group is running, or

[0005] -drx-RetransmissionTimerDL (DRX downlink retransmission timer) or drx-RetransmissionTimerUL (DRX uplink retransmission timer) is running on any serving cell in the DRX group, or

[0006] The `-ra-ContentionResolutionTimer` (contention resolution timer) or `msgB-ResponseWindow` (msgB response window) is running, or

[0007] - The scheduling request is sent and pending on the physical uplink control channel (PUCCH), or

[0008] - a physical downlink control channel (PDCCH) indicating a new transmission addressed to a cell radio network temporary identifier (C-RNTI) of the MAC entity has not been received after successfully receiving a random access response for a random access preamble that is not selected by the media access control (MAC) entity among contention-based random access preambles.

[0009] DRX off state or sleep state or DRX off period means that the UE is not in active time or outside of active time.

[0010] With the development of wireless communication technology, through the use of high frequency bands, large bandwidths, multiple antennas and other technologies, the performance indicators of wireless communication systems such as transmission rate, delay, throughput and reliability have been greatly improved. eXtended Reality (XR) and cloud gaming are some of the most important 5G media applications being considered in the industry. XR includes performance forms such as Augmented Reality (AR), Mixed Reality (MR) and Virtual Reality (VR), as well as fields interspersed between them. The services of XR include video, audio, posture / control, etc. 5G services (e.g., XR and cloud gaming services) require high reliability, high throughput and low latency. Since the devices used for XR include head-mounted displays or glasses with independent capabilities, the battery usage time of the XR device has a great influence on the user equipment (UE) experience. Therefore, how to reduce the power consumption of the UE is an important topic to be discussed. SUMMARY

[0121] In the present disclosure, the drx-onDurationTimer can be referred to as an on-duration timer or onDurationTimer.

[0122] In the present disclosure, the DRX On state can be equivalent to a DRX on period or a DRX on duration.

[0123] In the present disclosure, the long DRX cycle can be equivalent to a DRX long cycle.

[0124] In the present disclosure, a monitor occasion can be equivalent to a monitoring occasion.

[0125] In the present disclosure, a DRX off state or a sleep state or a DRX off period means that the UE is not in an active time or outside of an active time.

[0126] In the present disclosure, a drx-startoffset can be equivalent to a start offset or startoffset.

[0127] Figure 2 A schematic diagram of a wake-up signal (WUS) is shown according to an embodiment of the present disclosure.

[0128] In Figure 2 In the present disclosure, a DRX off state or a sleep state or a DRX off period means that the UE is not in an active time or outside of an active time.

[0129] In addition, a PS-offset (power saving offset) indicates a time at which the UE starts monitoring PDCCH for detecting DCI format 2_6 according to the number of search space sets before the time slot in which the drx-onDurationTimer is started on a primary cell (PCell) or a secondary primary cell (SpCell) in accordance with the following equation.

[0130] If the UE reports a MinTimeGap value for an activated DL BWP, the MinTimeGap value is X time slots before the start of the time slot in which the UE starts the drx-onDurationTimer, the UE does not need to monitor PDCCH for detecting DCI format 2_6 during the X time slots, where X corresponds to the MinTimeGap value for the sub-carrier spacing (SCS) of the activated DL BWP (Downlink bandwidth part) in Table 1 below.

[0131] Table 1 Minimum time gap value X

[0132]

[0133] In some embodiments, the UE monitors the PDCCH for detecting the DCI format 2_6 during the active time (e.g., DRX active duration / state / period). Figure 2 In some embodiments, the occasion for the UE to monitor the DCI format 2_6 is determined by the PS-offset and a minimum time interval value X.

[0134] In an embodiment of the WUS, the UE does not monitor the PDCCH for detecting the DCI format 2_6 during the active time (e.g., DRX active duration / state / period).

[0135] The present disclosure provides methods for reducing the power consumption of the UE. In addition, the signaling overhead of the signal is reduced. Further, the power for monitoring the signal is also reduced. The methods provided in the present disclosure also have good backward compatibility.

[0136] The operation at the UE side is described in the following.

[0137] In an example, the UE performs DRX to monitor the PDCCH. In this example, the UE determines the location of the start of the drx-onDurationTimer according to at least one of the first signaling or a pre-defined condition, and starts the drx-onDurationTimer at the determined location. The first signaling can be monitored during a certain time period / time window. Note that the term “time period” is used in some embodiments, and the term “time window” is used in other embodiments. In the present disclosure, the time period can be equivalent to the time window.

[0138] In an example, the UE can need to determine when to monitor the first signaling. For example, the time period / time window is the duration for the UE to monitor the first signaling. The time window is determined according to at least one of the following: a first reference point, a first offset, a second reference point, a second offset, a window length, a timer, a jitter range / window, a jitter value, a PDB (packet delay budget), traffic information, a minimum time interval, a monitoring pattern. In some embodiments, these parameters are referred to as time window parameters or first signaling parameters.

[0139] In an example, the time window parameters include a monitoring period. The monitoring period indicates the periodicity / period of the first signaling.

[0140] In some embodiments, at least one of the following is pre-defined: the first reference point, the second reference point, the second offset, and the minimum time interval.

[0141] In some embodiments, at least one of the following is configured by higher layer signaling: the first offset, the second offset, the window length, the timer, the jitter range / window, the jitter value, the PDB, the traffic information, the minimum time interval, and the monitoring period. In some embodiments, the higher layer signaling is at least media access control control element (MAC CE) signaling or RRC (Radio Resource Control) signaling.

[0142] In an example, the start of the time window is associated with the first reference point. For example, the time window starts at a time instance that is a slot, a subframe, a millisecond, a system frame after (e.g., immediately after) the first reference point.

[0143] In an example, the start of the time window is associated with the first reference point and a first offset. The first offset is a time duration between a slot of the start of the time window and a slot of the first reference point.

[0144] Figure 3 A diagram of a time window is shown in accordance with an embodiment of the disclosure. In Figure 3 In an example, the first reference point is a time instance (e.g., the first time instance) at which the UE is to start the drx-onDurationTimer (e.g., the start of the DRX active duration period). In this embodiment, the start of the time window is a (first) offset before the first reference point.

[0145] Figure 4 A diagram of a time window is shown in accordance with an embodiment of the disclosure. In Figure 4 In an example, the first reference point is a time instance (e.g., the first time instance) at which the UE is to start the drx-onDurationTimer (e.g., the start of the DRX active duration period). In this embodiment, the start of the time window is a (first) offset before the first reference point.

[0146] In some embodiments, the first reference point is associated with a system frame number (SFN) or a system frame.

[0147] In some embodiments, the first reference point can be one of the following:

[0148] - a system frame or a slot or a subframe before the start of a slot at which the UE is to start the drx-onDurationTimer;

[0149] - the system frame or slot or subframe after the last slot before the expiry of the drx-onDurationTimer or drx-inactivityTimer;

[0150] - the end position of the expiry of the drx-onDurationTimer or drx-inactivityTimer;

[0151] - the first subframe of each system frame;

[0152] - the SFN;

[0153] - the system frame;

[0154] - the Xth subframe of every Yth SFN, where X is an integer greater than or equal to 0 and less than 10, and Y is an integer greater than or equal to 0 and less than 513;

[0155] - the start of the system frame;

[0156] - the end of the system frame;

[0157] - the end of the slot in which the on-duration timer for the next DRX cycle is started;

[0158] - the slot or subframe of the start of the jitter window;

[0159] - the slot or subframe of the end of the jitter window;

[0160] - the acknowledgement (ACK);

[0161] - the PDSCH (Physical downlink shared channel);

[0162] - the slot or subframe in the middle of the jitter window.

[0163] In an embodiment, the system frame is indicated / represented by the SFN.

[0164] In some embodiments, the first reference point is associated with the slot of the start of the jitter window. Figure 5 A diagram illustrating a time window is shown in accordance with an embodiment of the disclosure. As Figure 5 shown, the first reference point is the slot of the start of the jitter window, and the start of the time window is the (first / second) offset before the first reference point.

[0165] In some embodiments, the first reference point is the end position of the slot in which the UE starts the drx-onDurationTimer.

[0166] In some embodiments, the first reference point is a slot of an end of the jitter window.

[0167] Note that the jitter is the offset between the data packet generation time and the time when the data packet arrives at the base station (e.g., gNB). The length of the jitter window represents the range of the jitter. For example, the jitter can be within [-4ms, 4ms] and the length of the jitter window is 8ms. In other words, the jitter window can be regarded as the range in which the data packet can arrive at the gNB.

[0168] In some embodiments, the jitter window is a location where the UE monitors the PDCCH.

[0169] In some embodiments, the jitter window is a location where the UE monitors the PDCCH for XR traffic.

[0170] In some embodiments, the jitter window is associated with a SPS (Semi-persistent scheduling) / CG (configured grant) configuration or a SPS / CG group.

[0171] In some embodiments, the first offset is associated with at least one of the following: PDB, jitter range, protocol data unit (PDU) set, quality indicator of the PDU set, traffic parameter(s).

[0172] In an embodiment, the traffic parameter(s) associated with the first offset comprises at least one of the following: QoS (quality of service), traffic periodicity, FPS (frame per second), priority information.

[0173] In an embodiment, the first offset is equal to or less than half of the PDB.

[0174] In an embodiment, the first offset is a value associated with the PDB value.

[0175] In an embodiment, the first offset is a value associated with the traffic parameter.

[0176] In an embodiment, the first offset is a value associated with the FPS (value).

[0177] In an embodiment, the first offset is a value associated with the PDU set.

[0178] In an embodiment, the first offset is a value associated with a quality indicator of the PDU set. For example, the first offset is configured according to the quality indicator of each PDU set. Alternatively or additionally, one first offset is configured to be associated with one quality indicator of the PDU set.

[0179] In an embodiment, the first offset is a value associated with a length of the jitter window.

[0180] In an embodiment, the first offset is a value associated with the traffic period.

[0181] In an embodiment, the first offset is equal to or less than half of the traffic period.

[0182] In an embodiment, the first offset is equal to or less than 1000 / FPS.

[0183] In an embodiment, the first offset can have different candidate values corresponding to different QoS values. For example, the candidate values and / or the mapping between the candidate values and the QoS values can be predefined. In another embodiment, each QoS value is associated with a first offset.

[0184] In an embodiment, the first offset can have different candidate values for different priority information values. For example, the candidate value corresponding to a low priority priority information value is less than or equal to the candidate value corresponding to a high priority priority information. In another embodiment, each priority is associated with a first offset.

[0185] In an example, the end of the time window is determined by at least one of the following: the second reference point, the (second) offset, the minimum time interval, the window length, the jitter range, the jitter window, the number of monitoring occasions.

[0186] In some embodiments, the second reference point can be / include at least one of the following:

[0187] - the start of the slot in which the UE starts the drx-onDurationTimer;

[0188] - the last slot before the expiry of the drx-onDurationTimer or drx-inactivityTimer;

[0189] - the end position of the expiry of the drx-onDurationTimer or drx-inactivityTimer;

[0190] - the SFN;

[0191] - the system frame;

[0192] - the start of the slot of the jitter window;

[0193] - the end of the slot where the UE starts the drx-onDurationTimer;

[0194] - the slot of the end of the jitter window.

[0195] In some embodiments, the end of the time window is determined by at least a second reference point and a second offset, wherein the second offset is a duration between the second reference point and the end of the time window.

[0196] In some embodiments, the UE continuously monitors the first signaling until the UE detects the first signaling indicating to start the on-duration timer.

[0197] In some embodiments, the second offset is a minimum time interval, and the second reference point is a start of a slot where the UE starts the drx-onDurationTimer.

[0198] In some embodiments, the end of the time window is determined by at least a first reference point, a first offset, and a window length. For example, the first reference point and / or the first offset are used to determine a start of the time window, and the time window ends at the window length after the determined start.

[0199] In some embodiments, the end of the time window and / or the window length is associated with a jitter range. For example, the window length is determined according to the jitter range. In an embodiment, the window length is equal to the jitter range. In another embodiment, the window length is smaller than the jitter range.

[0200] In some embodiments, the second offset is associated with at least one of: a UE capability, a predefined value, an SCS (subcarrier spacing), a higher layer signaling. For example, the predefined value is predefined to be associated with different SCSs and different UE capabilities. The second offset is configured by the higher layer signaling, and the value of the configured second offset should not be smaller than the predefined value.

[0201] In some embodiments, the window length is associated with at least one of: a PDB, a jitter range, a traffic parameter, a PDU set, or a quality indicator of a PDU set.

[0202] In an embodiment, the traffic parameter(s) associated with the window length include at least one of: a QoS (quality of service), a traffic periodicity, an FPS (frames per second), or a priority information.

[0203] In an embodiment, the window length is equal to or larger than half of the PDB.

[0204] In an embodiment, the window length is equal to or larger than half of the traffic periodicity.

[0205] In an embodiment, the window length is equal to or greater than 1000 / FPS.

[0206] In an embodiment, the window length can have same or different candidate values corresponding to different QoS values. For example, the candidate values and / or the mapping between the candidate values and the QoS values can be predefined.

[0207] In an embodiment, the window length can have same or different candidate values for different priority information values. For example, the candidate value corresponding to a low priority priority information value is less than or equal to the candidate value corresponding to a high priority priority information.

[0208] In some embodiments, the UE stops monitoring the first signaling if the UE has monitored a certain number of monitoring occasions for the first signaling.

[0209] In some embodiments, the UE stops monitoring the first signaling if a timer expires. In these embodiments, the timer can be triggered at the start of the time window.

[0210] In some embodiments, the UE monitors a certain number of (partial) slots from the start of the time window in each monitoring occasion, a certain number of monitoring occasions, or a certain number of periods of the first signaling.

[0211] In some embodiments, the UE monitors a certain number of (partial) slots from the start of the time window in the slots of each monitoring occasion, a certain number of monitoring occasions, or a certain number of periods of the search space set of the first signaling.

[0212] In an example, the monitoring pattern of the first signaling can be configured or indicated by the signaling. The monitoring pattern can comprise at least one of the following: a monitoring period, a pattern, or a bitmap. For example, the signaling configuring / indicating the monitoring pattern can be DCI or MAC CE signaling.

[0213] In some embodiments, the monitoring pattern indicates that the UE monitors the first signaling only in odd slots (i.e., slots with odd indices).

[0214] In some embodiments, the monitoring pattern comprises a monitoring period. The unit of the monitoring period is subframe or millisecond. The UE monitors the first signaling if (SFN*10 + subframe number) mod (monitoring period) = I, where I is an integer greater than or equal to 0 and less than the monitoring period.

[0215] In some embodiments, the monitoring pattern comprises a monitoring periodicity. In these embodiments, the unit of the monitoring periodicity is a slot. The UE monitors the first signaling if (numberOfSlotsPerFrame x SFN + slot number / index in the frame) mod (monitoring periodicity) = I, where I is an integer greater than or equal to 0 and less than the monitoring periodicity.

[0216] In the present disclosure, the term "mod" denotes the modulo function. For example, the result of one number NUM_1 mod another number NUM_2 is the remainder of NUM_1 divided by NUM_2.

[0217] Figure 6 A schematic diagram illustrating a monitoring pattern according to an embodiment of the present disclosure is shown. In the present embodiment, the monitoring pattern comprises a monitoring periodicity. As shown, the monitoring periodicity indicates certain valid slots, and the UE only monitors the first signaling in these indicated valid slots if a search space set for the first signaling is configured in these indicated valid slots during the time window. Figure 6

[0218] In some embodiments, the monitoring pattern comprises a bitmap. The bitmap length can be equal to or less than the time window. In the bitmap, one bit corresponds to one or more slots or milliseconds. For example, bit '1' indicates valid, while bit '0' indicates invalid. Based on the bitmap, the UE only monitors the first signaling in the valid slots during the time window if a search space set for the first signaling is configured in these valid slots.

[0219] In an embodiment, the length / duration of the time window is 10 slots, and the bitmap comprises 5 bits '00111'. In this embodiment, the bitmap can be repeated during the time window. That is, the UE monitors the first signaling in the 3rd, 4th, 5th, 8th, 9th, and 10th slots in the time window. Alternatively, one bit in the bitmap represents 2 slots. In other words, the UE monitors the first signaling in the 5th, 6th, 7th, 8th, 9th, 10th slots in the time window.

[0220] In an example, the first signaling indicates at least one of:

[0221] - whether to start the drx-onDurationTimer,

[0222] - when to start the drx-onDurationTimer,

[0223] - a duration,

[0224] - a temporary offset,

[0225] - a change offset,​

[0226] - search space set group index.

[0227] The information / parameter(s) indicated by the first signaling is discussed below.

[0228] In some embodiments, 1 bit in the first signaling is used to indicate whether to start the drx-onDurationTimer after the duration. For example, bit ‘1’ indicates to start the drx-onDurationTimer after the duration. In addition, bit ‘0’ indicates to reserve or continuously monitor the first signaling or not to start the drx-onDurationTimer after the duration.

[0229] In some embodiments, the first signaling indicates a temporary offset. The temporary offset is used to determine when to start the drx-onDurationTimer. For example, temporary offset = 0 indicates to continuously monitor the first signaling or not to start the drx-onDurationTimer after the duration. In an embodiment, temporary offset = A, where A is a positive integer, indicates to start the drx-onDurationTimer after A slots / milliseconds.

[0230] In some embodiments, the first signaling indicates a duration. The duration is used to determine / indicate when to start the drx-onDurationTimer. For example, duration = 0 indicates to continuously monitor the first signaling or not to start the drx-onDurationTimer. In an embodiment, duration = A, where A is a positive integer, indicates to start the drx-onDurationTimer after A slots / milliseconds. In an embodiment, RRC signaling configures one or more candidate values of the duration. The first signaling indicates one of the candidate values. For example, RRC signaling configures a list of durations or a list of candidate values of durations. In addition, bit X indicated by the first signaling (e.g., included in the first signaling) indicates the (X+1)th duration or candidate value in the list. In some embodiments, the duration can also be used to determine the starting position of the on duration timer when a pre-defined condition is met.

[0231] In some embodiments, the first signaling indicates a change offset for drx-startoffset. The change offset for drx-startoffset is used to change the drx-startoffset. For example, change offset = A1 (where A1 is an integer greater than or equal to 0) indicates that the drx-startoffset is adjusted / changed by the change offset (e.g., drx-startoffset = drx-startoffset + change offset).

[0232] Note that the temporary offset or duration can be configured to determine the time (after receiving the first signaling) to start the drx-onDurationTimer for the next long DRX cycle. The varying offset can be configured to vary the drx-startoffset (after receiving the first signaling) for all subsequent long DRX cycles. That is, the varying offset can affect the time to start the drx-onDurationTimer in all subsequent long DRX cycles.

[0233] In some embodiments, the first signaling indicates a search space set group index. When the drx-onDurationTimer is started / running, the UE monitors PDCCH according to the indicated search space set group index.

[0234] In an example, the first signaling can be DCI or sequence-based signaling.

[0235] In some embodiments where the first signaling is DCI, the first signaling can be associated with at least one of the following configuration parameters: search space set, new RNTI, starting position of the indication information of the first signaling, DCI size of the first signaling, enabling signaling, QCL (Quasi Co Location) state, or TCI (Transmission Configuration Indication) state. These configuration parameters can be named as first signaling parameters.

[0236] In some embodiments, the first signaling parameters or configuration parameters are indicated by higher layer signaling.

[0237] In some embodiments, the first signaling parameters can include search space set and / or CORESET (Control resource set). The search space set and / or CORESET are used to determine the monitoring occasion of the DCI. In the following content, the search space set configuration method for the first signaling is described.

[0238] In some embodiments, the configuration of a search space includes at least one of the following:

[0239] -searchSpaceId (search space ID): the identity (ID) of the search space.

[0240] -controlResourceSetId (control resource set ID): the CORESET applicable to this search space.

[0241] - duration: the number of consecutive slots in which the search space lasts in each occasion.

[0242] - monitoringSlotPeriodicityAndOffset: the slot for PDCCH monitoring configured by a periodicity and an offset.

[0243] - monitoringSymbolsWithinSlot: the first symbol(s) for PDCCH monitoring in a slot configured for PDCCH monitoring.

[0244] - nrofCandidates: the number of PDCCH candidates per aggregation level.

[0245] In some embodiments, the configuration of the search space set for the first signaling has certain restrictions in order to reduce the possibility of blind decoding and save power.

[0246] In an embodiment, the number of search space sets for the first signaling is not greater than a first threshold A, where the first threshold A is an integer greater than 0 and less than 3. In another embodiment, the first threshold A is an integer greater than 0 and less than 4.

[0247] In an embodiment, the duration of the search space set for the first signaling is not greater than a second threshold B, where the second threshold B is an integer greater than 0 and less than 30. Note that the second threshold B can be associated with the SCS. For example, the second threshold B associated with a large SCS is greater than or equal to the second threshold B associated with a small SCS. In another embodiment, the second threshold B is an integer greater than 0 and less than 120.

[0248] In an embodiment, the periodicity of the search space set for the first signaling is not less than a third threshold C, where the third threshold C is an integer greater than 1. The third threshold C can be associated with the SCS. For example, the third threshold C associated with a large SCS is greater than or equal to the third threshold C associated with a small SCS.

[0249] In an embodiment, the number of aggregation levels of the search space set for the first signaling is not greater than a fourth threshold D, where the fourth threshold D is an integer greater than 0 and less than 3. Alternatively, the fourth threshold D is an integer greater than 0 and less than 5.

[0250] In an embodiment, the maximum value of the aggregation levels of the search space set for the first signaling is a fifth threshold E. For example, the fifth threshold E is an integer not greater than 8. In another example, the fifth threshold E is 4. In another example, the fifth threshold E is 2.

[0251] In an embodiment, the number of PDCCH candidates per aggregation level of the search space set for the first signaling is not greater than a sixth threshold F. The sixth threshold F can remain the same or change for different aggregation levels. For example, the sixth threshold F associated with a lower aggregation level can be greater than or equal to the sixth threshold F associated with a higher aggregation level. As an alternative, the sixth threshold F is an integer not greater than 2. In another example, the sixth threshold F is an integer not greater than 4.

[0252] In an embodiment, the total number of PDCCH candidates of the search space set for the first signaling is not greater than a seventh threshold G. For example, the seventh threshold G is an integer greater than 0 and less than 20. In another example, the seventh threshold G is an integer not greater than 24.

[0253] In an embodiment, the number of monitoring occasions in one slot of the search space set for the first signaling is not greater than an eighth threshold H. The eighth threshold H can be an integer greater than 0 and less than 3. In another embodiment, the eighth threshold H is an integer not greater than 3.

[0254] In some embodiments, the DCI format can be scrambled by a new RNTI.

[0255] In an embodiment, the new RNTI is used for (scrambling) a DCI indicating whether XR traffic will be transmitted.

[0256] In an embodiment, the new RNTI is used for (scrambling) a DCI indicating whether to start drx-onDurationTimer after a duration. In this embodiment, the duration can be a predefined value, or indicated by the first signaling or by another higher layer signaling.

[0257] In an embodiment, the new RNTI is used for a DCI indicating a duration or a temporary offset or a varying offset.

[0258] In an embodiment where the duration is a predefined value, the predefined value is associated with a SCS. For example, the predefined value associated with a large SCS is greater than or equal to the predefined value associated with a small SCS.

[0259] In an embodiment where the duration is a predefined value, the predefined value is a minimum time interval or a second offset.

[0260] In an embodiment where the duration is a predefined value, the predefined value is 0.

[0261] In an embodiment where the duration is indicated by the first signaling or configured by another higher layer signaling, one SCS can be associated / configured according to one duration. For example, the duration associated with a large SCS can be configured to be greater than or equal to the duration associated with a small SCS.

[0262] In an embodiment where the duration is configured by the first signaling or another higher layer signaling, the first signaling or the higher layer signaling can configure a list of candidate values for the duration. In this embodiment, the corresponding DCI indicates one of the candidate values as the duration.

[0263] In an embodiment, the duration is associated with a predefined gap. In this embodiment, the UE does not expect to be indicated or configured with a duration value that is smaller than the predefined gap. The predefined gap can be the same or different for different SCS. For example, the predefined gap corresponding to a smaller SCS is not larger than the predefined gap corresponding to a larger SCS. In an embodiment, the predefined gap has different values for different UE capabilities. In an embodiment, the predefined gap is the minimum time gap.

[0264] In an embodiment, a new RNTI is used for (scrambling) the DCI indicating whether to change drx-startoffset.

[0265] In an embodiment, a new RNTI is used for (scrambling) the DCI indicating whether to monitor the DCI in the next / next monitoring occasion.

[0266] In some embodiments, the size (e.g., DCI size) of the first signaling is not larger than a ninth threshold J. The ninth threshold J can be an integer larger than 0 and smaller than 30. For example, the ninth threshold J is 24. As an alternative, the ninth threshold J is 18. As another alternative, the ninth threshold J is 12.

[0267] In an embodiment, the size of the first signaling can be different from a DCI scrambled with a RNTI other than C-RNTI.

[0268] In an embodiment, if a search space set for the first signaling is configured in a serving cell, the UE is expected to monitor up to 5 PDCCH candidates of DCI formats of sizes including up to 3 DCI formats of sizes with CRC scrambled by C-RNTI in the serving cell.

[0269] In an embodiment, when the UE is monitoring (in a time window) the first signaling, the UE is expected to monitor up to 5 PDCCH candidates of DCI formats of sizes including up to 3 DCI formats of sizes with CRC scrambled by C-RNTI in the serving cell.

[0270] In an embodiment, if one of the 5 sizes of DCI formats is the size of the first signaling when monitoring the first signaling (in the time window), the UE is expected to monitor PDCCH candidates of up to 5 sizes of DCI formats.

[0271] In some embodiments, the higher layer signaling indicates the starting position of the indication information in the first signaling (e.g., DCI).

[0272] In some embodiments, the first signaling comprises one or more blocks. Each block comprises one or more bits. Each block is associated with one UE or UE group. The one or more bits in one block comprise the indication information for the associated UE or the associated UE group. In an embodiment, the UE group is configured by the higher layer signaling.

[0273] In an embodiment, the first signaling is DCI format 2_6 with a new RNTI. The field(s) in the DCI format 2_6 are repurposed to indicate the indication information.

[0274] In some embodiments, if the number of monitoring occasions associated with the search space set configuration is greater than 1, different monitoring occasions or slots in one duration can be associated with different or the same CORESET index.

[0275] In an embodiment, the number of monitoring occasions can be one of:

[0276] - the number of monitoring symbol groups of the first signaling in one slot associated with the search space set configuration;

[0277] - the number of monitoring symbol groups of the first signaling in one duration associated with the search space set configuration;

[0278] - the number of monitoring symbol groups or monitoring slots in a time window associated with the search space set configuration;

[0279] - the number of slots in one duration associated with the search space set configuration,

[0280] - the number of monitoring symbol groups of the first signaling in one slot;

[0281] - the number of monitoring symbol groups of the first signaling in one duration;

[0282] - the number of monitoring symbol groups or monitoring slots in a time window;

[0283] - the number of slots in one duration.

[0284] In an embodiment, one monitoring occasion represents the monitoring occasion of the first signaling in one slot or in one slot in one duration.

[0285] In an embodiment, one monitoring occasion represents a monitoring occasion of the first signaling associated with the search space set in the time window.

[0286] In an embodiment, the number of monitoring symbol groups in a slot of the first signaling is the number of values ‘1’ configured in monitoringSymbolsWithinSlot.

[0287] In an embodiment, a “monitoring symbol group” is equivalent to a “monitoring occasion”.

[0288] In an embodiment, one monitoring occasion is associated with one CORESET. The relationship between a monitoring occasion and a CORESET can be indicated by RRC signaling.

[0289] In an embodiment, one monitoring occasion is associated with one CORESET. In this embodiment, the relationship between a monitoring occasion and a CORESET can be derived.

[0290] In some embodiments, the RRC signaling configures a list of CORESETs. The number of CORESETs in the list of CORESETs is A, and the number of monitoring occasions in a time interval is B.

[0291] In an embodiment where A = B, the first monitoring occasion is associated with the first CORESET in the list of CORESETs, the second monitoring occasion is associated with the second CORESET in the list of CORESETs, and so on.

[0292] In an embodiment where A < B, the i-th monitoring occasion is associated with the mod(i, A)-th CORESET in the list of CORESETs. That is, the first monitoring occasion is associated with the first CORESET, …, the A-th monitoring occasion is associated with the A-th CORESET in the list of CORESETs, the (A+1)-th monitoring occasion is associated with the first CORESET in the list of CORESETs, the (A+2)-th monitoring occasion is associated with the second CORESET in the list of CORESETs, and so on.

[0293] In an embodiment where A < B, the monitoring occasions are divided into A groups. Each group is associated with one CORESET in the list of CORESETs. For example, the number of monitoring occasions in some groups can be equal to [round down(B / A)]. The number of monitoring occasions in the last group is determined by the following formula:

[0294] B - (A - 1) * [round down(B / A)].

[0295] Note that [round down(B / A)] means the quotient of B divided by A is rounded down to an integer, which is the largest integer less than the quotient.

[0296] The monitoring occasions are divided into groups in order. That is, the first round down(B / A) monitoring occasions are in the first group and are associated with the first CORESET in the CORESET list, and so on.

[0297] Note that the above mapping method is for a time interval being one search space set period (i.e., the duration of a search space set) or one slot or time window. For another time interval, the mapping function is the same.

[0298] The time interval can also be one or more consecutive search space set periods (i.e., multiple durations of a search space set) or one or more consecutive slots. The monitoring occasions can also be changed to one or more consecutive monitoring occasions or one or more consecutive slots.

[0299] Figure 7 A schematic diagram of monitoring occasions of the first signaling according to an embodiment of the disclosure is shown. In this embodiment, the first signaling parameters are configured as:

[0300] - monitoringSlotPeriodicityAndOffset: periodicity = 4 slots, offset = 1 slot;

[0301] - duration: 2 slots

[0302] - monitoringSymbolsWithinSlot: 14 bits Figure 1 0 0 0 1 0 0 0 0 1 0 0 0 0

[0303] - controlResourceSetld: 2, 0

[0304] As shown in Figure 7 , the number of monitoring occasions in one slot of the first signaling is 3 (located at symbols 0, 4, 9). The first monitoring occasion in the slot is associated with the CORESET which is the first CORESET configured in the search space set. The second monitoring occasion in the same slot is associated with the second CORESET configured in the search space set, and the third monitoring occasion in the same slot is associated with the first CORESET. The order is arranged from low index to high index.

[0305] Figure 8 A schematic diagram of monitoring occasions of the first signaling according to an embodiment of the disclosure is shown. In this embodiment, the first signaling parameters are configured as:

[0306] - monitoringSlotPeriodicityAndOffset: period = 4 slots, offset = 1 slot;

[0307] - duration: 3 slots;

[0308] - controlResourceSetld: 2.

[0309] In Figure 8 , the number of slots in one duration is three, and the first monitoring occasion is associated with CORESET 2 configured in the search space set. The next monitoring occasion is associated with CORESET 0. For other monitoring occasions in one duration, the relationship between monitoring occasion and CORESET is repeated in order. In other words, if mod(i / 2) = 1, the ith monitoring occasion in one duration is associated with a CORESET configured in the search space set; otherwise, the ith monitoring occasion in one duration is associated with CORESET 0. That is, monitoring occasions with odd indices and monitoring occasions with even indices are associated with different CORESETs (in this embodiment, one is CORESET 0 and the other is a CORESET configured in the search space set). In some embodiments, only one CORESET can be associated with the search space set. A default CORESET can be used for different monitoring occasions. In this example, the default CORESET is CORESET 0.

[0310] Note that although only two CORESETs 0 and 2 are used in the embodiments shown in Figure 7 and Figure 8 , in other embodiments, the number of CORESETs for the monitoring occasions of the first signaling can be greater than 2. In some embodiments, the CORESETs for the monitoring occasions of the first signaling are configured by RRC signaling.

[0311] In an embodiment, a monitoring occasion is associated with a CORESET, meaning that the CORESET is applicable to the monitoring occasion in the search space.

[0312] In an embodiment, a monitoring occasion is associated with a CORESET, meaning that the TCI state or QCL of the monitoring occasion uses the TCI state or QCL of the CORESET.

[0313] In some embodiments, if the number of monitoring occasions is more than one, a list of CORESETs is configured in the search space set. In this embodiment, each monitoring occasion can be associated with one CORESET in the list of CORESETs.

[0314] In an embodiment, the number of CORESETs in the CORESET list is the same as the number of monitoring occasions. The mapping between CORESETs and monitoring occasions can be one-to-one mapping.

[0315] In an embodiment, the number of CORESETs in the CORESET list is less than the number of monitoring occasions. In this embodiment, multiple monitoring occasions can be mapped to one CORESET. For example, the number of CORESETs in the CORESET list is Num_A, the number of monitoring occasions is Num_B, and the ith monitoring occasion is mapped to (or associated with) the jth CORESET, where j = mod(i / num_A). As an alternative, the monitoring occasions can be divided into Num_A groups. Except for the last group, the group(s) include function(Num_B / Num_A) monitoring occasions, and the last group includes Num_B-(Num_A-1)*function(Num_B / Num_A) monitoring occasions. The monitoring occasions in the ith group are associated with the ith CORESET in the list. The function can be a floor function or a ceiling function.

[0316] In some embodiments, if the number of monitoring occasions is more than one, different monitoring occasions or slots in one duration can be associated with different or the same TCI state.

[0317] In an embodiment, one search space can be associated with a list of TCI states. In this embodiment, one monitoring occasion is associated with one TCI state in the list of TCI states. In this embodiment, the mapping between monitoring occasions and TCI states can be the same as the mapping between monitoring occasions and CORESETs.

[0318] In some embodiments, if the first signaling is more than one in the monitoring occasion(s) in one slot, different monitoring occasions can be associated with different or the same SSB (Synchronization Signal block).

[0319] In an embodiment, the mapping between monitoring occasions and SSBs can be the same as the mapping between monitoring occasions and CORESETs.

[0320] In an embodiment, the association of a monitoring occasion with an SSB means that the demodulation reference signal (DMRS) port of the monitoring occasion is quasi co-located with the SSB.

[0321] In some embodiments, the first signaling is sequence based signaling or a reference signal.

[0322] In an example, the UE monitors the first signaling during a time period / time window. Note that during the active time of DRX, the UE can not monitor the first signaling. That is, if the time window is within the active time, the UE does not monitor the first signaling within the time window.

[0323] In embodiments where a portion of the time window is within the active time, the UE monitors the first signaling in the portion of the time window that is outside the active time. As an alternative, if the time window at least partially overlaps with the active time, the UE does not monitor the first signaling in the time window. As another alternative, the UE monitors the first signaling in the time window even if a portion of the time window overlaps with the active time.

[0324] In some embodiments, the UE monitors the first signaling if at least one of the following occurs:

[0325] - the UE is outside the active time;

[0326] - the UE is configured with a search space for the first signaling;

[0327] - the UE receives an enabling / activating signaling;

[0328] - the UE is within a time period / time window;

[0329] - the UE receives a first signaling indicating to monitor the first signaling continuously;

[0330] - the UE does not receive a first signaling indicating to start drx-onDurationTimer after a duration.

[0331] In an embodiment, the enabling / activating signaling can be a MAC CE or a DCI or a RRC signaling.

[0332] In an embodiment, the enabling / activating signaling indicates to enable or start monitoring the first signaling.

[0333] In some embodiments, the UE stops monitoring the first signaling if at least one of the following occurs:

[0334] - the UE is within the active time;

[0335] - the UE is outside a time period (a time window);

[0336] - the UE receives a first signaling indicating to start drx-onDurationTimer after a duration.

[0337] In an example, the predefined condition is associated with at least one of the following: a timer, a time window, a DCI format, an RNTI, an enabling signaling, a UE capability signaling.

[0338] In some embodiments, the predefined condition is satisfied if at least one of the following occurs:

[0339] a) the UE does not detect, during a time window, a first signaling indicating to start the drx-onDurationTimer after a time duration;

[0340] b) the UE receives an enabling signaling:

[0341] In an embodiment, the enabling signaling indicates to enable changing the drx-startoffset.

[0342] In an embodiment, the enabling signaling indicates to enable monitoring the first signaling.

[0343] c) the UE reports a UE capability signaling:

[0344] In an embodiment, the capability signaling indicates that the UE supports monitoring the first signaling;

[0345] d) a timer expires:

[0346] In an embodiment, the timer is triggered / re-triggered if a scheduling DCI is received.

[0347] In an embodiment, the timer is triggered / re-triggered if a scheduling DCI for an XR service / traffic is received.

[0348] In an embodiment, the timer is triggered / re-triggered if the first signaling is received.

[0349] In an embodiment, the timer is triggered / re-triggered if a first type of DCI format is received. For example, the first type of DCI format can comprise at least one of the following: a DCI for an XR service / traffic, DCI format 0_1, DCI format 1_1, DCI format 0_2, DCI format 1_2, DCI format 2_6.

[0350] In an embodiment, the UE activates the timer in a first slot outside of an activation time.

[0351] In an embodiment, the timer is activated in a first slot after the expiration of the drx-onDurationTimer or the drx-inactivityTimer or the drx-retransmissionTimer (DRX retransmission timer).

[0352] e) receiving the first type of DCI format:

[0353] For example, the first type of DCI format can comprise at least one of the following: DCI for XR service / traffic, DCI format 0_1, DCI format 1_1, DCI format 0_2, DCI format 1_2, DCI format 2_6.

[0354] f) receiving the DCI scrambled with the first type of RNTI:

[0355] For example, the first type of RNTI can comprise at least one of the following: new RNTI (e.g., for XR service / traffic), PS-RNTI (Power Saving-RNTI), C-RNTI, CS-RNTI (Configured Scheduling RNTI), MCS-C-RNTI (Modulation and Coding Scheme cell RNTI).

[0356] In an example, the position of the start of the DRX on duration timer is determined based on the first signaling and / or the predefined condition. For example, if the predefined condition is met, the UE determines the position of the start of the DRX on duration timer and receives the first signaling.

[0357] In some embodiments, the predefined condition is that the UE does not detect the first signaling indicating to start the drx-onDurationTimer after the time duration during a time window. If the UE detects the first signaling indicating to start the drx-onDurationTimer after the time duration during the time window, the position of the start of the DRX on duration timer is indicated by the first signaling or the position of the start of the DRX on duration timer is after the time duration after the first signaling (the time of receiving the first signaling). Otherwise, if the predefined condition is met, the position of the start of the DRX on duration timer is still at the original position.

[0358] In some embodiments, the predefined condition is that the UE receives the enabling signaling. If the UE detects the first signaling indicating to start the drx-onDurationTimer after the time duration during a time window and the predefined condition is met, the position of the start of the DRX on duration timer is after the time duration after the first signaling (the time of receiving the first signaling). Otherwise, the position of the start of the DRX on duration timer is at the original position.

[0359] In an example, the location of the start of the DRX on duration timer is determined by a predefined condition. For example, if the predefined condition is met, the location of the start of the DRX on duration timer is the duration after the predefined condition is met.

[0360] In an example, the location of the start of the DRX on duration timer is determined by the first signaling. For example, if the UE detects the first signaling indicating to start drx-onDurationTimer after a duration during the time window, the location of the start of the DRX on duration timer is indicated by the first signaling. That is, the location of the start of the DRX on duration timer is the duration after the first signaling (the time of receiving the first signaling).

[0361] In an example, if the UE does not detect the first signaling indicating to start drx-onDurationTimer after a duration during the time window, one of the following will happen:

[0362] A) The UE starts drx-onDurationTimer for the next long DRX cycle:

[0363] In some embodiments, if an SSSG (search space set group) is configured before receiving the DCI during the activation time, the UE monitors PDCCH according to a default SSSG. For example, the default SSSG can be predefined or configured by RRC signaling. Alternatively, the default SSSG can be the SSSG with the highest index or the SSSG with the lowest index.

[0364] In some embodiments, during the activation time, the UE only monitors DL DCI before receiving the DCI.

[0365] B) The UE starts drx-onDurationTimer after a duration for the next long DRX cycle:

[0366] In some embodiments, if an SSSG is configured before receiving the DCI during the activation time, the UE monitors PDCCH according to a default SSSG. For example, the default SSSG can be predefined or configured by RRC signaling. Alternatively, the default SSSG can be the SSSG with the highest index or the SSSG with the lowest index.

[0367] In some embodiments, during the activation time, the UE only monitors DL DCI before receiving the DCI.

[0368] C) the UE does not start the drx-onDurationTimer for the next long DRX cycle;

[0369] D) the UE determines whether to start the drx-onDurationTimer for the next long DRX cycle according to a higher layer signaling:

[0370] In some embodiments, the higher layer signaling indicates whether to start the drx-onDurationTimer for the next long DRX cycle.

[0371] In some embodiments, if the higher layer signaling is not configured, the UE performs a default behavior. The default behavior can be predefined.

[0372] In an example, if the UE is unable to monitor the first signaling during the time window (e.g., because the time window is within the active time, there is no available monitoring occasion for the first signaling), one of the following will happen:

[0373] A) the UE starts the drx-onDurationTimer for the next long DRX cycle at the original location.

[0374] B) the UE starts the drx-onDurationTimer for the next long DRX cycle after the duration.

[0375] C) the UE determines whether to start the drx-onDurationTimer for the next long DRX cycle according to a higher layer signaling:

[0376] In some embodiments, the higher layer signaling indicates whether to start the drx-onDurationTimer for the next long DRX cycle.

[0377] In some embodiments, if the higher layer signaling is not configured, the UE performs a default behavior. The default behavior can be predefined.

[0378] In an example, the UE does not expect to be configured with DCP (DCI with CRC scrambled by PS-RNTI) and the first signaling parameter at the same time.

[0379] In an example, the UE is configured with DCP and the first signaling parameter at the same time. In this example, the first signaling parameter includes an enabling signaling. The enabling signaling indicates whether the UE monitors the first signaling or whether the first signaling is enabled. If the enabling signaling indicates that the UE monitors the first signaling, or the enabling signaling indicates that the first signaling is enabled, the UE monitors the first signaling and does not monitor the DCP; otherwise, the UE monitors the DCP and does not monitor the first signaling.

[0380] In an example, the DCP and the first signaling are associated with different CORESETs.

[0381] In an example, the UE monitors the first signaling in a PCell (primary cell), a PSCell (primary secondary cell), or a ssCell (SCell used for scheduling PCell / PSCell (secondary cell)).

[0382] In an example, the UE can monitor the first signaling in each activated serving cell.

[0383] In some embodiments, the UE does not expect to receive inconsistent indication information at the same time. For example, the UE does not expect to receive inconsistent indication information in one slot, one monitoring occasion, or one millisecond.

[0384] In an example, the indication information indicated in the first signaling is used for a UE group. The group to which the UE belongs is configured by higher layer signaling.

[0385] Figure 9 A schematic diagram of a time window is shown according to an embodiment of the disclosure. In Figure 9 In the embodiment, the first signaling is DCI. In addition, the time window is determined according to a first reference point, a first offset, and a minimum time interval. In this embodiment, the first reference point is predefined as the start of the slot in which the UE starts the drx-onDurationTimer. The first offset is configured by RRC signaling. The first offset indicates the duration between the starting position of the time window and the first reference point. The end of the duration is the slot or millisecond of the minimum time interval before the first reference point. The DCI indicates whether to start the drx-onDurationTimer after the duration for the next long DRX cycle. The duration is equal to the minimum time interval. After the UE receives the DCI indicating to start the drx-onDurationTimer after the minimum time interval, the UE stops monitoring the first signaling (i.e., DCI) and starts the drx-onDurationTimer after the minimum time interval. If the UE does not detect the DCI indicating to start the drx-onDurationTimer after the minimum time interval during the time window, the UE starts the drx-onDurationTimer at the original position of the DRX active duration for the next long DRX cycle.

[0386] Figure 10 A schematic diagram of a time window is shown according to an embodiment of the disclosure. In Figure 10In some embodiments, the first signaling is DCI, and the time window is determined according to a first reference point, a first offset, a second reference point, and a minimum time interval. In this embodiment, the first reference point is predefined as the start of the slot in which the UE starts the drx-onDurationTimer. The first offset is configured by RRC signaling and is configured to indicate a time duration between the start position of the time window and the first reference point. The second reference point is (predefined as) the end of the drx-onDurationTimer of the next long DRX cycle. Note that the end of the time window is the slot, millisecond of the minimum time interval before the second reference point. The DCI indicates whether to start the drx-onDurationTimer after the time duration for the next long DRX cycle. The time duration is equal to the minimum time interval. After the UE receives the DCI indicating to start the drx-onDurationTimer after the minimum time interval, the UE stops monitoring the first signaling (i.e., DCI) and starts the drx-onDurationTimer after the minimum time interval. If the UE does not detect the DCI indicating to start the drx-onDurationTimer after the minimum time interval during the time window, the UE does not start the drx-onDurationTimer at the original position of the DRX active duration for the next long DRX cycle.

[0389] The processor 1100 can implement any of the steps in the exemplary embodiments on the wireless terminal 110 (e.g., by executing the program codes 1112).

[0390] The communication unit 1120 can be a transceiver. Alternatively or additionally, the communication unit 1120 can combine a transmission unit and a reception unit configured to transmit and receive signals to and from a wireless network node (e.g., a base station), respectively.

The wireless network node 120 may be a satellite, base station (BS), network entity, Mobility Management Entity (MME), Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), radio access network (RAN) node, next-generation RAN (NG-RAN) node, gNB, eNB, gNB central unit (gNB-CU), gNB distributed unit (gNB-DU), data network, core network, or Radio Network Controller (RNC), and is not limited thereto.

[0395] Figure 13 A schematic diagram of a method according to an embodiment of the present disclosure is shown. Figure 13 The method shown can be used in a wireless terminal (e.g., a UE) and includes the following steps:

[0396] Step 1301: Execute DRX to monitor PDCCH.

[0397] Step 1302: Determine the starting position of the activation duration timer for the next DRX cycle based on at least one of the first signaling or a predefined condition.

[0398] Step 1303: Activate the activation duration timer at the determined starting position.

[0399] exist Figure 13 In the illustrated embodiment, the wireless terminal performs DRX to monitor the PDCCH. When performing DRX, the UE determines the start position of the activation duration timer for the next DRX cycle based on at least one of a first signaling or one or more predefined conditions. In this embodiment, the first signaling is monitored over a time period. That is, the UE can monitor the first signaling and / or determine whether one or more predefined conditions are met within this time period to determine the start position of the activation duration timer. The UE activates the activation duration timer at the determined start position. In other words, the UE enters a DRX active state at the determined start position, for example, to monitor the PDCCH.

[0400] In one embodiment, the time period is determined by a monitoring period that indicates the cycle of the first signaling.
