Delay status reporting in presence of skippable radio resource management (RRM) measurement period

Abstract

Various aspects of the present disclosure relate to a user equipment (UE), base station, method, and processor for wireless communication that reduces discarding of delay-critical uplink data. The UE receives, from the base station, a configuration including an indication of a dynamic delay status reporting parameter and an indication of a first uplink grant preceding a measurement period. In response to determining a time distance to the measurement period is within a dynamic reporting time window, the UE determines whether at least one data unit of delay-critical data is not accommodated by the first uplink grant and has an assigned discard time to occur during the measurement period. To avoid discarding the delay-critical data, the UE transmits delay status reporting to the base station. The UE receives a second uplink grant in response and transmits the delay-critical data according to the second uplink grant, before the assigned discard time.

Description

DELAY STATUS REPORTING IN PRESENCE OF SKIPPABLE RADIO RESOURCE MANAGEMENT (RRM) MEASUREMENT PERIOD PRIORITY CLAIM

[0001] The present application claims priority to U.S. provisional application No. 63 / 633,658, filed on April 12, 2024, the entire contents of which are incorporated herein. TECHNICAL FIELD

[0002] The present disclosure relates to wireless communications, and more specifically scheduling delay-critical uplink data for wireless communications. BACKGROUND

[0003] A wireless communications system may include one or multiple network communication devices, such as base stations, that may support wireless communications for one or multiple user communication devices, which are also called user equipment (UE) or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communications system, including time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers, or the like). Additionally, the wireless communications system may support wireless communications across various radio access technologies, such as including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, and other suitable radio access technologies beyond 5G (e.g., sixth generation (6G)). SUMMARY

[0004] Some implementations of the method and apparatuses described herein may include performing wireless communications between a user equipment (UE) and a base station that reduces discarding of delay-critical uplink data, thereby improving a user experience for applications such as eXtended Reality (XR) applications. In some Docket No. SMM920240039-WO-PCTimplementations of the method and apparatuses described herein, a UE for wireless communication provides improved delay status reporting for flexible measurement period cancellation. In one or more embodiments, the UE includes a transceiver, at least one memory, and at least one processor coupled with the transceiver and the at least one memory. The at least one processor is configured to cause the UE to receive, from a base station, one or more configuration. The one or more configuration includes an indication of a dynamic delay status reporting parameter and an indication of a first uplink grant preceding a measurement period. The at least one processor is configured to cause the UE to determine, based on the dynamic delay status reporting parameter, a first time distance (“Ta”) and a second time distance (“Tb”) to the measurement period. The first time distance Ta is greater than the second time distance Tb. In response to determining time distance (“Td”) to the measurement period is within a dynamic reporting time window between first time distance Ta and second time distance Tb, the at least one processor is configured to cause the UE to trigger and subsequently transmit delay status reporting in an uplink transmission to the base station, in response to the UE determining that at least one data unit of the delay-critical data is not accommodated by the first uplink grant and has an assigned discard time to occur during the measurement period. In an example, the UL resources assigned by the first uplink grant carry the delay status reporting (DSR).

[0005] In some implementations of the method and apparatuses described herein, a base station for wireless communication provides increased flexibility in prioritizing data communication and control channel monitoring over radio resource management measurements. In one or more embodiments, the base station includes at least one memory and at least one processor coupled with the at least one memory. The at least one processor is configured to cause the base station to transmit one or more configurations to the UE. The one or more configurations include an indication of a dynamic delay status reporting parameter and an indication of a first uplink grant preceding a measurement period. The one or more configurations prompt the UE to determine, based on the dynamic delay status reporting parameter, a first time distance (“Ta”) and a second time distance (“Tb”) to the measurement period that define a dynamic reporting time window. At a time distance (“Td”) to the measurement period that is within the dynamic reporting time window, the base station receives delay status reporting from the UE. The UE sends the delay status reporting based Docket No. SMM920240039-WO-PCTon determining that at least one data unit of delay-critical data is not accommodated by the first uplink grant and has an assigned discard time to occur during the measurement period.

[0024] Aspects of the present disclosure address delay status reporting in the presence of a skippable radio resource management (RRM) measurement period. As conventionally specified, during measurement gaps or periods, a user equipment (UE) is not required to conduct reception / transmission from / to a corresponding new radio (NR) serving cell for standalone (SA) mode with single carrier or carrier aggregation (CA) configured. As an exception, reception of signals used for RRM measurement(s), position reference signal (PRS) measurement(s), and the signals used for random access procedure may still occur during a measurement gap.

[0025] A UE can communicate with a gNB to support eXtended Reality (XR) features. XR refers to all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables. XR is an umbrella term for different types of realities including Virtual reality (VR), Augmented reality (AR), and Mixed reality (MR), and the areas interpolated among them. The levels of virtuality range from partially sensory inputs to fully immersive VR. A key aspect of XR is the extension of human experiences, especially relating to the senses of existence (represented by VR) and the acquisition of cognition (represented by AR). To achieve an effective user experience, XR data uploaded by the UE to the gNB may be delay critical.

[0026] Conventionally, during measurement periods of specific measurement types (e.g., intra-frequency RRM measurements (FR2), or measurement gaps, certain scheduling Docket No. SMM920240039-WO-PCTrestrictions are applicable that could degrade the system throughput (e.g., depending on the periodicity and length of the measurement gap). In case of eXtended Reality (XR) traffic, the number of satisfied UEs (i.e., UEs with most of their packet data unit (PDU) sets being delivered within the PDU-Set Delay Budget) has been shown to drop to no more than 50% for some measurement configurations due to scheduling restrictions during measurement periods. The general concept of using DCI or MAC-CE signaling has been suggested to de- activate or skip the scheduling restrictions during a next measurement period to improve the number of satisfied UEs in case of XR traffic. However, the conventional indication (DCI or MAC-CE) needs to be sent a certain time (e.g., ~ 5ms) earlier than the beginning of the next measurement period.

[0027] For an XR application, a data stream (e.g., video, sensor, etc.) should be delivered within its latency budget. For a new radio base node (gNB) to timely decide if an RRM measurement gap is to be de-activated to provide extra resources for communicating undelivered data approaching its maximum allowable delay, the gNB should know if an uplink (UL) PDU-set is approaching its delay budget with enough time in advance so that gNB can de-active the upcoming RRM measurement period and schedule the PDU-set in an UL transmission overlapping with the measurement period, if needed.

[0028] The present disclosure provides enhancements to the DSR mechanism to ensure that the gNB can de-activate an RRM measurement period in time for scheduling such a delay-critical UL transmission in that period. As used herein, skipping / deactivating / relaxing scheduling restrictions and skipping / cancelling RRM measurements / measurement periods / MGs are used interchangeably unless clearly stated otherwise. These techniques essentially mean data communication and control channel monitoring are enabled during the measurement periods. Measurement gap and RRM measurement period are used interchangeably unless clearly stated otherwise. Remaining time / Remining Delay Budget is the smallest remaining value of the Packet Data Convergence Protocol (PDCP) discard timers (“PDCP discardTimers”) among service data units (SDUs) buffered for the logical channel group (LCG) as specified.

[0029] Various aspects of the present disclosure relate to a user equipment (UE), base station, method, and processor for wireless communication that reduces discarding of delay- Docket No. SMM920240039-WO-PCTcritical uplink data. The UE receives, from the base station, one or more configurations including an indication of a dynamic delay status reporting parameter and an indication of a first uplink grant preceding a measurement period. In one or more embodiments, the one or more configurations configure the UE to decide between performing with a dynamic DSR threshold or fixed ("configured”) DSR threshold. In one or more embodiments, the one or more configurations are received at different times to configure the UE with one of dynamic and fixed DSR thresholds. In one or more embodiments, the indication of the first uplink grant is received in a different, later configuration signal from the indication of the dynamic DSR. In response to determining a time distance to the measurement period is within a dynamic reporting time window, based on the configuration, the UE determines whether at least one data unit of delay-critical data is not accommodated by the first uplink grant and has an assigned discard time to occur during the measurement period. To avoid discarding the delay-critical data, the UE transmits delay status reporting to prompt the base station to cancel the measurement period and to schedule an additional uplink resource for the delay- critical data.

[0030] Figure 1 illustrates an example of a wireless communications system 100 in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more network entity (NE) 102, one or more user equipment (UE) 104, and a core network (CN) 106. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a fourth generation (4G) network, such as an LTE network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a new radio (NR) network, such as a fifth generation (5G) network, a 5G-Advanced (5G-A) network, or a 5G ultrawideband (5G-UWB) network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G, for example, 6G. Additionally, the wireless communications system 100 may support different technologies, such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA), etc. Docket No. SMM920240039-WO-PCT

[0031] The one or more NE 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the NE 102 described herein may be, or may include, or may be referred to as a network node, a base station, a network element, a network function, a network equipment, a network entity, a radio access network (RAN), a NodeB, an eNodeB (eNB), a next-generation NodeB (gNB), or other suitable terminology. An NE 102 and a UE 104 may communicate via a communication link, which may be a wireless or wired connection. For example, an NE 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.

[0032] An NE 102 may provide a geographic coverage area for which the NE 102 may support services for one or more UEs 104 within the geographic coverage area. For example, an NE 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc.) according to one or multiple radio access technologies. In some implementations, an NE 102 may be moveable, for example, a satellite associated with a non-terrestrial network (NTN). In some implementations, different geographic coverage areas associated with the same or different radio access technologies may overlap, but the different geographic coverage areas may be associated with different NE 102.

[0033] The one or more UE 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a remote unit, a mobile device, a wireless device, a remote device, a subscriber device, a transmitter device, a receiver device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (IoT) device, an Internet-of-Everything (IoE) device, or machine-type communication (MTC) device, among other examples.

[0034] A UE 104 may be able to support wireless communication directly with other UEs 104 over a communication link. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link may be referred Docket No. SMM920240039-WO-PCTto as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.

[0035] An NE 102 may support communications with the CN 106, or with another NE 102, or both. For example, an NE 102 may interface with other NE 102 or the CN 106 through one or more backhaul links (e.g., S1, N2, N2, or network interface). In some implementations, the NE 102 may communicate with each other directly. In some other implementations, the NE 102 may communicate with each other or indirectly (e.g., via the CN 106). In some implementations, one or more NE 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC). An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as radio heads, smart radio heads, or transmission-reception points (TRPs).

[0036] The CN 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The CN 106 may be an evolved packet core (EPC), or a 5G core (5GC), which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) and / or an access and mobility management functions (AMF)) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc.) for the one or more UEs 104 served by the one or more NE 102 associated with the CN 106.

[0037] The CN 106 may communicate with a packet data network over one or more backhaul links (e.g., via an S1, N2, N2, or another network interface). The packet data network may include an application server. In some implementations, one or more UEs 104 may communicate with the application server. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the CN 106 via an NE 102. The CN 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server using the established session (e.g., the established PDU session). The PDU Docket No. SMM920240039-WO-PCTsession may be an example of a logical connection between the UE 104 and the CN 106 (e.g., one or more network functions of the CN 106).

[0038] In the wireless communications system 100, the NEs 102 and the UEs 104 may use resources of the wireless communications system 100, including time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) to perform various operations (e.g., wireless communications). In some implementations, the NEs 102 and the UEs 104 may support different resource structures. For example, the NEs 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the NEs 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the NEs 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures). The NEs 102 and the UEs 104 may support various frame structures based on one or more numerologies.

[0039] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., =0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., =0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., =1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., =2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., =3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., =4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.

[0040] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames). Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame Docket No. SMM920240039-WO-PCTmay have the same duration. In some implementations, each subframe of a frame may have the same duration.

[0041] Additionally, or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., =0, =1, =2, =3, =4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively.^Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing), a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., =0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.

[0042] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz – 7.125 GHz), FR2 (24.25 GHz – 52.6 GHz), FR3 (7.125 GHz – 24.25 GHz), FR4 (52.6 GHz – 114.25 GHz), FR4a or FR4-1 (52.6 GHz – 71 GHz), and FR5 (114.25 GHz – 300 GHz). In some implementations, the NEs 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the NEs 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data). In some Docket No. SMM920240039-WO-PCTimplementations, FR2 may be used by the NEs 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.

[0043] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies). For example, FR1 may be associated with a first numerology (e.g., =0), which includes 15 kHz subcarrier spacing, a second numerology (e.g., =1), which includes 30 kHz subcarrier spacing, and a third numerology (e.g., =2), which includes 60 kHz subcarrier spacing. FR2 may be associated with numerologies (e.g., at least2 numerologies). For example, FR2 may be a numerology (e.g., =2), which includes 60 kHz subcarrier spacing, and a fourth numerology (e.g., =3), which includes 120 kHz subcarrier spacing.

[0044] FIG.2 is an example timing diagram 200 illustrating DSR triggering by the UE according to a dynamic threshold when a current time distance is in proximity of a MG. FIG. 3 is an example timing diagram 300 illustrating DSR triggering according to a configured (“fixed” or non-dynamic) threshold when the current time distance is far from a MG. FIG.4 is a communication diagram 400 illustrating DSR signaling exchange between a UE 401 and a new radio base node (gNB) 402 in proximity of a MG, according to a one or more embodiments. As shown by the figure at 405, UE 401 triggers DSR. At 410, gNB 402 transmits first uplink grant 410 on the downlink. At 415, the UE 401 transmits the DSR 415 on the UL resources provided by the 1st UL grant 410. At 420, gNB 402 triggers cancellation of the MG on the network side. In one or more embodiments, the gNB 402 explicitly sends an MG cancellation indication 425 on the downlink to the UE 401. The MG cancellation indication to the UE 401 can be an implicit indication (e.g., when gNB sends the 2nd UL grant 430 with UL resources overlapping with the MG) or can be included in the 2nd UL grant. UE 401 transmits delay-critical data 435 using the 2ndUL grant resources.

[0045] As an alternative to the above described embodiments, in another embodiment,the UE triggers a DSR at time “t1” if the remaining delay budget (or RDB- ) for an LCG (attime “t1”) is to be exceeded in an upcoming RRM measurement period, where is prior to the beginning of a MG and where , is the time needed for cancelling the MG by gNB, and where: Docket No. SMM920240039-WO-PCT

[0046] “lb” being lower bound and “ub” being upper bound. Parameters and in the above embodiments can be determined as follows: is: (i) ‘0’; (ii) a specified non-zero value; or (iii) configured by the network (e.g., 0 or 1 slot). is: (i) related to a processing time by gNB for the processing of a DSR (and preparation and transmission of the MG cancellation command by gNB, and SR transmission in case no UL resource is available); (ii) configured (e.g., 1 slot); or (iii) determined to be a predefined value from a reference time, which can be the time that is prior to the beginning of a MG (as shown in FIG. 6). and can be determined based on configuration.

[0047] In another embodiment, if there is an upcoming cancellable MG, the UE triggers a DSR if , and . In other words, the dynamic DSR threshold is satisfied when the time distance to the measurement gap is greater than a minimum time for cancellation signaling specified by the base station, which can include a factor for processing time required by the base station.

[0048] FIG.5 presents a flow-chart of a method 500 of dynamic and fixed DSR triggering by a UE. In one or more embodiments, at block 505, UE begins a loop for the next measurement group. The UE expedites DSR triggering, i.e., the UE triggers DSR sooner than the time allotted for a DSR triggering criteria, based on checking, at block 510, if RDB is smaller than a configured threshold, in proximity of an upcoming MG (i.e., dynamic DSR threshold is satisfied). The expedited or earlier DRS triggering ensures that the gNB has at least certain time to cancel the MG to enable data transmission, and reception, as well as control channel monitoring during the MG. In response to determining that the dynamic DSR threshold of block 510 is not satisfied, the UE determines whether a fixed DSR threshold is satisfied (dMGTMG+ ). In response to the fixed DSR threshold of block 515 not being satisfied, method 500 returns to block 505. In response to the determinations of either block 510 or block 515 being satisfied, method 500 proceeds to block 520 where the UE next determines if an upcoming MG (which is not necessarily the immediate upcoming MG) is Docket No. SMM920240039-WO-PCTcancellable. The MG is cancellable if the associated MG configuration or any other network indication (e.g., via radio resource control (RRC) signaling) has enabled the upcoming MG to be cancelable / skippable. In response to determining that the upcoming MG is not cancellable in block 520, the method 500 returns to block 505. In response to determining that the MG is cancellable in block 520, in block 525, the UE triggers the DSR. Then the method 500 returns to block 505.

[0049] For clarity, method 500 is for evaluating DSR for one MG. If there are multiple MGs (e.g., FIG. 10) overlapping or close-to-each other, the UE first resolves overlap or performs prioritization amongst the MGs, and then checks DSR triggering criteria (e.g., repeating operation as shown in FIG.5 for each MG). If there are multiple upcoming MGs (e.g., after resolving overlap between MGs or after prioritization of the MGs), the UE performs the check for DSR triggering (e.g., as shown in FIG. 5) for each upcoming MG, e.g., from the earliest to the latest. Once a DSR is triggered for the LCG, the UE would not check the triggering condition for the rest of the MGs or the UE would start a DSR-prohibit timer for the LCG, and the UE checks again when the DSR-prohibit timer expires. The DSR- prohibit timer associated with MG cancellation can be different than a DSR-prohibit timer associated with RDB being smaller than a threshold. If there is a triggered DSR (e.g., due to RDB<threshold) for the LCG, then there is no need to check the triggering condition related to MG. The upcoming measurement period is determined to be a measurement period selected from a set of overlapping or close-to-each other measurement periods / occasions (i.e., the distance between the two measurement occasions is equal to or smaller than a certain threshold time). The measurement period is selected as a result of a prioritization procedure performed by the UE amongst the set of overlapping or close-to-each other measurement periods (e.g., FIG.10).

[0050] According to a second embodiment, a new DSR cancellation rule is provided. FIG. 6 is an example timing diagram 600 illustrating advancing DSR triggering due to proximity to a cancellable RRM measurement period. In an embodiment, a previously triggered DSR with dynamic triggering threshold or with configured triggering threshold(i.e., a pending DSR) is cancelled not earlier than “ ” time units prior to the start of an activeMG if the RDB is going to be exhausted within the MG. As a motivation, a pending DSR in Docket No. SMM920240039-WO-PCTgeneral should not be cancelled unless that DSR is not useful if transmitted. Hence, to give as much chance as possible to the UE to send delay-critical UL data, the UE cancels the associated pending DSR if the DSR is too close to the MG, in which case transmitting thatDSR would not be useful. The value assigned to “ ” can depend on a physical uplink sharedchannel (PUSCH) preparation time (e.g.,,as defined), and a DSR processing time, and can be configured ( , ), wherein “ ” is configured or determined, in anexample, such that is integer slots.

[0051] One or more related embodiments to the above-described embodiment are presented in FIGs. 8 - 10. FIG. 8 is an example timing diagram 800 illustrating a DSR triggered time (T0), RDB expiration during a measurement gap, and a DSR cancellation window. The present disclosure provides a process of data in LCG associated with RDB being discarded and the corresponding PDCP discard timer being updated within DSR cancellation window . In a related embodiment, the UE does not trigger a DSR or the UE cancels a triggered / pending DSR if four conditions all exist. The first condition is that the time gap between the DSR triggering time (e.g., when RDB < threshold) and the start of the MG is less than the time needed for scheduling a PUSCH transmission (e.g.,,. The second condition is that the corresponding RDB becomes zero or negative prior to the end of the MG. The third condition is that there is no configured grant (CG) resource which can beused for transmission of a packet associated with the LCG during the time gap ( ). Thefourth condition is that the MG is not canceled.

[0052] FIG.9 is an example timing diagram 900 illustrating DSR not being triggered ora triggered DSR being canceled if there is less than a minimum processing time ( , )left from the transmission occasion of the DSR prior to an active MG. In anthe UE triggers / sends a DSR to the network as before (when RDB<threshold). If an MG cancellation timeline is satisfied (e.g., if the time gap between the time the DSR is sent and the starting time of the MG is at least ), the UE transmits the associated LCG within the MG. In other words, sending the DSR implies that the UE will cancel the MG, and so the network (gNB) and the UE are on the same page with respect to the MG cancellation status). As an example, in response to receiving the DSR, the gNB assumes that the UE will cancel Docket No. SMM920240039-WO-PCTthe MG if the RDB is going to be expired / exhausted during the MG or within a vicinity of the MG.

[0053] FIG.10 is an example timing diagram 1000 illustrating the UE cancelling a MG when the UE triggers a DSR if RDB < threshold and the time gap between the DSR triggering time and the start of the MG is larger than time needed for the UE to cancel the MG( ).

[0054] If the UE has already received an indication which has canceled a set of upcoming MGs, including the MG satisfying , the DSR is triggered as before (if RDB<threshold). If the UE cancels an MG (e.g., based on some rules, such as based on L3 measurement reports or L1 CSI reports) without need to receive a subsequent command from the network to cancel the MG, the DSR is triggered as before (if RDB<threshold).

[0055] The UE triggers a DSR (e.g., based on decisions rules considering RDB, and a MG, e.g., as shown in FIG.5) if the UE has indicated to the network that the MG may / can be skipped (assuming the UE needs to receive a subsequent command from the network to cancel the MG). The indication can be an explicit indication or an implicit indication. For instance, the UE may indicate that the UE is in a low mobility state (e.g., by indicating a low mobility criterion is satisfied).

[0056] FIG. 11 is a diagram 1100 of advancing DSR triggering due to proximity to a cancellable RRM measurement period. If the gNB deactivates the MG via a MAC-CEindication, the applicability of the MAC-CE takes effect ‘ ’ time units (e.g., 3msec) after theMAC-CE is acknowledged, and therefore, the cancellation timeline requirement increases by‘ ’ as shown in FIG. 11Error!
