Description

Technical Field

[0001] This document is generally aimed at wireless communication, especially fifth-generation wireless communication, and specifically at the configuration of discontinuous reception (DRX). Background Technology

[0002] Since XR (Extended Reality) services are typically quasi-periodic services with burst arrival time jitter, C-DRX (Connectivity-Mode DRX) can be used to match the burst arrival pattern of XR services and conserve UE (User Equipment) power. That is, the UE monitors the PDCCH (Physical Downlink Control Channel) to send and / or receive XR data during the active duration of C-DRX (e.g., when a duration timer is enabled), and stops monitoring the PDCCH during the inactive period of C-DRX to conserve power. Several aspects may need to be considered when applying C-DRX to XR services. Summary of the Invention

[0162] Figure 10 A flowchart of a method according to an embodiment of the present disclosure is shown. Detailed Implementation

[0163] In this embodiment, the frame rate of the XR service (e.g., 15 fps, 30 fps, 45 fps, 60 fps, 72 fps, 90 fps, and 120 fps) corresponds to periods that are not multiples of the C-DRX cycle and are not integer factors of 1024 ms (66.66 ms, 33.33 ms, 22.22 ms, 16.66 ms, 13.88 ms, 11.11 ms, and 8.33 ms), respectively (e.g., the C-DRX cycle can be configured in milliseconds). Under these conditions, a mismatch will occur between the XR service periodicity and the DRX cycle due to cycle mismatch and SFN (System Frame Number) wrap-around issues. Figure 1 A schematic diagram illustrating a mismatch between the arrival time of XR services and the DRX cycle after SFN surround is shown, according to an embodiment of this disclosure. Figure 1 As shown, the mismatch between the XR service cycle and the DRX cycle may cause the DRX cycle to be out of sync with the arrival time of XR services after SFN surround.

[0164] This disclosure provides a C-DRX method applicable to XR services and their devices. It should be noted that the method disclosed herein can be applied to uplink configuration scheduling mechanisms (e.g., CG (Configuration Grant)) and / or downlink configuration scheduling mechanisms (e.g., SPS (Semi-Persistent Scheduling)). Furthermore, the C-DRX in this disclosure is not limited to XR services and can also be applied to other types of services.

[0165] C-DRX Periodic Configuration

[0166] In this embodiment, the XR frame rate (e.g., 15fps, 30fps, 45fps, 60fps, 72fps, 90fps, and 120fps) corresponds to a period (e.g., 200 / 3ms, 100 / 3ms, 200 / 9ms, 50 / 3ms, 125 / 9ms, 100 / 9ms, and 3 / 25ms, respectively). To ensure that the C-DRX period is consistent with the XR frame rate, the UE is configured with an XR frame rate (e.g., a data burst frequency), such as 15, 30, 45, 60, 72, 90, and 120fps, and the UE uses the equation 1000ms / XR frame rate (e.g., the XR frame rate can be the data burst frequency) to calculate the C-DRX period or CG / SPS period; or a non-integer period (e.g., a fractional period) is configured as the C-DRX period.

[0167] In this embodiment, the score period can be represented by enumerating score values. For example, the score period can be represented by the following pseudocode:

[0168] Periodicity NUMERATED{3per200ms,3per100ms,9per200ms,3per50ms,9per125ms,9per100ms,3per25ms}.

[0169] It should be noted that the 3per200ms indicator period is 200 / 3ms, the 3per100ms indicator period is 100 / 3ms, and so on.

[0170] As an alternative or supplement, the fractional period is represented by (indicating) the numerator and denominator. For example, the fractional period can be represented by the following pseudocode: Periodicity::= SEQUENCE{

[0171] numerator ENUMERATED{25, 50, 100, 125, 200}

[0172] denominator ENUMERATED{3,9},

[0173] }

[0174] In this embodiment, the period is indicated as (numerator / denominator) ms.

[0175] In an embodiment, the C-DRX non-integer (e.g., fractional) period configuration method can also be used to configure non-integer (e.g., fractional) periods for CG and / or SPS.

[0176] C-DRX activation duration start timing SFN and subframe

[0177] In some embodiments, the C-DRX on-time start timing is determined based on the XR (non-integer) period to eliminate the mismatch between the CDRX period and the XR non-integer period and to avoid the SFN wrap-around problem.

[0178] In this embodiment, the SFN and subframe number at the start of the C-DRX activation duration can be determined by the following:

[0179] floor([((1024×m+SFN)×10)+subframe_number]modulo(drx-periodicity))=floor([((SFN start time (×10)+subframe start time modulo(drx-periodicity))

[0180] (Equation 2-1)

[0181] When C-DRX is activated, m = 0, and m increments each time SFN = 0; SFN is the SFN at the start of the C-DRX activation duration, and subframe_number is the subframe number at the start of the C-DRX activation duration. start time and subframe start time These are the SFN and subframe at the start of the first (first) C-DRX activation duration; and drx-periodicity, which is the (non-integer or fractional) period of C-DRX. In the embodiment, when / if C-DRX is activated, the SFN is explicitly indicated. start time and subframe start time .

[0182] In this embodiment, the SFN and subframe number / index at the start of the C-DRX activation duration can be determined by the following:

[0183] floor([((1024×m+SFN)×10)+subframe_number]modulo(drx-periodicity))=floor([((timeReferenceSFN)×10)-timeDomainOffset]modulo(drx-periodicity))

[0184] (Equation 2-2)

[0185] When C-DRX is activated, m = 0, and m increments each time SFN = 0. SFN is the SFN at the start of the C-DRX activation duration, subframe_number is the subframe number at the start of the C-DRX activation duration, drx-periodicity is a non-integer period, and timeReferenceSFN and timeReferenceSFN are indicated in the C-DRX configuration information and / or used to determine the start of the first C-DRX activation duration.

[0186] In this embodiment, the SFN and subframe number at the start of the C-DRX activation duration can be determined by the following:

[0187] floor([((1024×m+SFN)×10)+subframe_number]modulo(drx-periodicity))=drx-StartOffset

[0188] (Equation 2-3)

[0189] When C-DRX is activated, m = 0, and m increments each time SFN = 0. SFN is the SFN at the start of the C-DRX activation duration, subframe_number is the subframe number at the start of the C-DRX activation duration, drx-StartOffset is explicitly indicated when C-DRX is activated and is used to determine the SFN and subframe at the start of the C-DRX activation duration; and drx-periodicity is the (non-integer or fractional) period of C-DRX.

[0190] In this embodiment, the SFN and slot number of the C-DRX activation duration start time can be determined as follows:

[0191] floor([((1024×m+SFN)×numberofSlotsPerFrame×10)+slot_number]modulo((drx-periodicity)×numberOfSlotsPerFrame÷10))=floor([((SFN start time )×numberOfSlotsPerFrame×10)+slot start time ]modulo((drx-periodicity)×numberOfSlotsPerFrame÷10)),

[0192] (Equation 2-4)

[0193] When C-DRX is activated, m = 0, and m increments each time SFN = 0; SFN is the SFN at the start of the C-DRX activation duration, and slot_number is the slot number at the start of the C-DRX activation duration. start_time and slot start_time These are the SFN and time slot number at the start of the first (first) C-DRX on-time duration when C-DRX is (re)configured or activated; and drx-periodicity, which is the (non-integer or fractional) period of C-DRX. In this embodiment, if C-DRX is (re)configured or activated, the SFN can be explicitly indicated (e.g., by the network or base station). start_time and slot start time .

[0194] In this embodiment, the SFN, slot number, and symbol number of the C-DRX activation duration start time can be determined by the following:

[0195] floor([((1024×m+SFN)×numberOfSlotsPerFrame×numberOfSymbolsPerSlot×10)+(slot_number×numberOfSymbolsPerSlot)+symbol_number]modulo((drx-periodicity)×numberOfSlotsPerFrame×numberOfSymbolsPerSlot÷10))=floor([((SFN start time )×numberOfvlotsPerFrame×numberOfSymbolsPerSlot×10)+(slot start time ×numberOfSymbolsPerSlot)+symbol start time ]modulo((drx_periodicity)×numberOfSlotsPerFrame×numberOfSymbolsPerSlot÷10)),

[0196] (Equation 2_5)

[0197] When C-DRX is activated, m = 0, and m increments each time SFN = 0; SFN is the SFN of the start time of C-DRX activation duration, slot_number is the slot number of the start time of C-DRX activation duration, and symbol_number is the symbol number of the start time of C-DRX activation duration. start time slotstart time and symbol start time These are the SFN, slot number, and symbol number at the start of the first (1st) C-DRX activation duration; and drx-periodicity, which is the (non-integer or fractional) period of the C-DRX. In this embodiment, the SFN can be explicitly indicated when / if the C-DRX is activated or (re)configured. start time slot start time and symbol start time .

[0198] In this embodiment, the SFN and subframe number at the start of the C-DRX activation duration can be determined by the following:

[0199] [(SFN×10)+subframe_number]=ceil([(timeReferenceSFN)×10-timeDomainOffset+N×(drx-periodicity)]modulo(10240))

[0200] (Equation 2-6)

[0201] Where SFN is the SFN of the C-DRX enable duration start time, subframe_number is the subframe number of the C-DRX enable duration start time, timeReferenceSFN and timeDomainOffset are used to indicate the first (1st) C-DRX enable duration start time; drx-periodicity is the (non-integer or fractional) period of C-DRX; and N is an integer greater than or equal to 0.

[0202] In this embodiment, the SFN and subframe number at the start of the C-DRX activation duration can be determined by the following:

[0203] [(SFN×10)+subframe_number]=ceil([SFN starttime ×10+subframe starttime +N×(drx-periodicity)]modulo(10240)),

[0204] (Equation 2-7)

[0205] Among them SFN start time and subframe start timeThese are the SFN and subframe number at the start of the first (1st) C-DRX activation duration, respectively; drx-periodicity is the (non-integer or fractional) period of C-DRX; and N is an integer greater than or equal to 0. In the embodiment, when / if C-DRX is activated, the SFN is explicitly indicated. start time and subframe start time .

[0206] In this disclosure, floor(X) is a function that determines / gets / computes the largest integer less than or equal to X. If the C-DRX period value is configured as an integer, floor() can be removed from each of Equations 2-1 to 2-5.

[0207] In this disclosure, ceil(X) is a function that determines / gets / computes the smallest integer greater than or equal to X. If the C-DRX period value is configured as an integer, ceil() can be removed from equation / equation 2-6 or equation 2-7.

[0208] In the embodiments, the equations / formulas for determining the temporal location (e.g., SFN, subframe number, symbol number, slot number) of the C-DRX activation duration start timing can be used to determine the resource timing of CG and / or SPS.

[0209] The start time of the first (first) DRX activation duration is determined.

[0210] When determining the start timing of the C-DRX activation duration, the UE may need to determine the time-domain location of the first timing when C-DRX is activated / reconfigured, or the start timing of the first (first) C-DRX activation duration (e.g., SFN). start time and subframe start time (For example, determining when m = 0 or N = 0 in equations / equations 2-1 to 2-5 and 2-7).

[0211] In some embodiments, C-DRX is (re)configured or activated via dedicated RRC (Radio Resource Control) signaling, and this dedicated RRC signaling can be retransmitted. Upon receiving dedicated RRC signaling, the UE has difficulty determining the timing of C-DRX activation or the time-domain location (e.g., SFN) of the start of the first (first) C-DRX activation duration. start time and / or slot start time and / or symbol start time For example, at H-SFN (super SFN) boundaries (e.g., SFN=1023 or SFN=0), the UE may have difficulty determining in which H-SFN the dedicated RRC signaling was first transmitted.

[0212] In an embodiment, an hsfn-LSB-Info with / possessing one bit is configured to the UE to indicate the LSB (least significant bit) of the H-SFN corresponding to the SFN of the first transmission including dedicated RRC signaling that includes C-DRX (re)configuration and / or activation.

[0213] As an alternative or supplement, the first (first) SFN starts the duration of the activation. start time and / or subframe start time and / or slot start time and / or symbol start time It is explicitly configured as: the starting SFN, and / or the starting subframe, and / or the starting time slot, and / or the starting symbol that indicates the start of the first C-DRX activation duration.

[0214] In this embodiment, the dedicated RRC signaling (re)transmission, including C-DRX (re)configuration (information), may not take more than 1024ms.

[0215] In an embodiment, timeReferenceSFN is configured to indicate the most recent SFN before or after receiving dedicated RRC signaling including C-DRX (re)configuration, or to indicate the most recent SFN before or after the first (first) transmission of dedicated RRC signaling including C-DRX (re)configuration and / or activation. timeReferenceSFN is used to determine the H-SFN of the C-DRX first activation duration start time (e.g., the start time of the first C-DRX activation duration start time), or the most recent SFN before or after the first C-DRX activation duration start time (e.g., in the case of m = 0 in equations 2-1 to 2-5, or in the case of N = 0 in equations 2-6 and 2-7).

[0216] In this embodiment, timeDomainOffset and timeReferenceSFN are configured to indicate the start timing of the first C-DRX activation duration, wherein:

[0217] The -timeReferenceSFN indicates the reference SFN used to determine the start time of the first C-DRX activation duration.

[0218] -timeDomainOffset indicates the offset between the reference SFN and the starting point of the first C-DRX start duration.

[0219] For example, the first on duration of the first C_DRX, starting at the SFN and subframe timing, is:

[0220] - Subtract timeDomainOffset from the most recent timeReferenceSFN boundary (e.g., SFN start or end time) before or after receiving the C-DRX configuration (including its RRC signaling), or

[0221] - Add timeDomainOffset to the most recent timeReferenceSFN boundary (e.g., SFN start or end timer) after receiving the C-DRX configuration (including its RRC signaling).

[0222] In this embodiment, the cost of (re)transmitting dedicated RRC signaling does not exceed the value step of timeReferenceSFN.

[0223] An example of configuring timeDomainOffset and timeReferenceSFN to indicate the start of the first C-DRX start duration can be applied to Equations 2-2 and 2-6.

[0224] In this embodiment, drx-Periodicity, drx-StartOffset, and timeReferenceSFN are configured to indicate the start time of the first C_DRX start duration, wherein:

[0225] -timeReferenceSFN indicates: the H-SFN used to determine the start time of the first C_DRX start duration, or the reference SFN of the most recent SFN before or after the start time of the first C_DRX start duration (e.g., m = 0 in Equation 2-3), and

[0226] -drxOffset and drxPeriodicity are used to determine the SFN and subframe at which the C_DRX enable duration begins (see, for example, Equation 2-3).

[0227] In this embodiment, the cost of (re)transmitting dedicated RRC signaling does not exceed the value of timeReferenceSFN.

[0228] CG HARQ process number determined

[0229] In some embodiments, for UL burst transmissions with large burst sizes or UL burst transmissions with burst arrival time jitter, multiple CG timings can be configured within a CG period. For example, Figure 2 Each CG cycle shown includes 5 CG opportunities. Note that the CG cycle can also be a C-DRX cycle.

[0230] In this embodiment, the CG timing is referred to as the CG resource timing.

[0231] In cases where there are multiple CG events within a single CG time period, the HARQ process ID can be determined using one of the following embodiments.

[0232] In this embodiment, a range of HARQ process IDs is configured for the CG. The UE selects a HARQ process ID from the range for the CG time slot and indicates the selected HARQ process ID along with the UL transmission on that CG resource time slot (e.g., via CG-UCI (CGUL Control Information) or subCG-UCI) to the gNB (e.g., BS). In this embodiment, the UE can autonomously perform a retransmission of a HARQ process using available UL resources (e.g., CG resources or UL grants scheduled by the gNB). If / when there is no UL data transmission on the CG time slot, the UE sends an indication to the gNB regarding the lack of UL data transmission on the CG time slot, so that the gNB can distinguish between a UL transmission failure and the absence of UL data transmission. When no UL information is received on the CG time slot, the gNB can assume that a UL transmission failure has occurred and schedule UL grants without allocating a HARQ process ID for UL retransmission.

[0233] In this embodiment, a HARQ process ID range is configured for each CG cycle. The HARQ process ID is determined for each CG cycle (e.g., multiple CG events within a CG cycle share the same HARQ process ID). For example, the HARQ process ID is determined as follows:

[0234] HARQ process ID=[floor(CURRENT_SYMBOL / periodicity)]modulo(nrofHARQ-Processes)+(harq-ProcID-Offset)

[0235] in,

[0236] CURRENT SYMBOL

[0237] =(SFN×nmnberOfSlotsPerFranm×munberofSynlbolsPerSlot)+slot number ×nmnberOfSynlbolsPerSlot+symbol_nmnber

[0238] Where numberOfSlotsPerFrame is the number of consecutive time slots per frame, numberOfSymbolsPerSlot is the number of consecutive symbols per time slot, nrofHARQ-Processes is the number of HARQ process IDs configured for multiple CG resource timings, and harq-ProclD-Offset is the first HARQ process ID configured for multiple CG resource timings.

[0239] In this embodiment, a HARQ process ID range is configured for CG. The HARQ process ID is determined at each CG time point during the CG cycle (or during the C-DRX cycle). For example, the HARQ process ID can be determined by the following:

[0240] HARQ process ID

[0241] =[floor(CURRENT_SYMBOL / CG_occasion_interval)]modulo(nrofHARQ-Processes)+(harq-ProcID-Offset)

[0242] in,

[0243] CURRENT SYMBOL =(SFN×mnnberOfSlotsPerFranm×nmnberofSymbolsPerSlot)+slot number ×numberofSymbolsPerSlot+symbol_number

[0244] Where `numberOfSlotsPerFrame` is the number of consecutive time slots per frame, `numberOfSymbolsPerSlot` is the number of consecutive symbols per time slot, `CG_occasion_interval` is the interval between two consecutive CG events, `nrofHARQ-Processes` is the number of HARQ process IDs configured for multiple CG resource events, and `harq-ProclD-Offset` is the first HARQ process ID configured for multiple CG resource events. For example, Figure 3 An example of the interval between two consecutive CG events is shown, namely CG_occasion_interval.

[0245] In this embodiment, the HARQ process ID for the CG timing is determined based on the CG timing sequence number. For example, the HARQ process ID for the CG timing can be determined by the following:

[0246] HARQ process ID

[0247] =CG_occasion_SequenceNumber modulo(nrofHARQ-Processes)+(harq-ProcID-Offset)

[0248] In this embodiment, harq-ProclD-Offset is the initial HARQ process ID that the CG can use, and nrofHARQ-Processes is the total number of HARQ process IDs that the CG can use. That is, the range of HARQ process IDs available for the CG is [harq-procID-offset,...,(harq-procID-offset+nrofHARQ-Processes-1)]. Furthermore, CG_occasion_SequenceNumber is the sequence number of the CG occasion (e.g., a UL license) during the CG cycle (or during the C-DRX cycle). For example, the CG_occasion_SequenceNumber for each CG in a CG cycle can be configured as follows: Figure 4 The CGO SN shown. Specifically, in Figure 4 In this sequence, the serial number of the first CG moment is 0, the serial number of the second CG moment is 1, and so on.
