Description

Technical Field

[0001] The present application relates to wireless communication systems, and more particularly to methods (and associated devices and systems) for adjusting various aspects of discontinuous reception (CDRX) operation and / or semi-persistent scheduling (SPS) operation of connections for extended reality (XR) communications and other wireless communications. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). A wireless multiple access communication system may include multiple base stations (BSs), each of which simultaneously supports communication with multiple communication devices, which may be further referred to as user equipment (UE). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM).

[0003] Extended reality (XR) continues to be a growing area of ​​wireless communication usage. XR may include augmented reality (AR), mixed reality (MR) and / or virtual reality (VR) devices, systems and / or communications. XR devices may be mobile devices (e.g., phones, tablets, glasses, watches, goggles, etc.) that facilitate XR wireless communications (including supporting wireless data exchange with servers). Many XR applications support dynamic reconstruction of three-dimensional (3D) environments and / or fusion of real-world environments with virtual environments. Therefore, XR applications may require high-quality video and / or audio data communications with low latency and / or variable number and / or size of data packets, which may result in significant power requirements for XR devices. At the same time, because many XR devices are wearable and mobile, users expect XR devices to provide good battery life and remain comfortable during use (e.g., avoid overheating), thereby providing an overall good user experience. Therefore, it is necessary to provide an efficient design for wireless data communications including XR data communications in a manner that delivers expected levels of communication latency and throughput to users while also providing power savings and extended battery life.

[0025] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. In order to provide a comprehensive understanding of the various concepts, the detailed description includes specific details. However, it is apparent to those skilled in the art that these concepts may be practiced without these specific details. In some aspects, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0026] The present disclosure as a whole relates to wireless communication systems, which are also referred to as wireless communication networks. In various aspects, various technologies and devices can be used for wireless communication networks, such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single carrier FDMA (SC-FDMA) networks, LTE networks, global mobile communication systems (GSM) networks, fifth generation (5G) or new radio (NR) networks and other communication networks. As described herein, the terms "network" and "system" can be used interchangeably.

[0027] OFDMA network can realize radio technology such as Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM, etc. UTRA, E-UTRA and GSM are part of Universal Mobile Telecommunications System (UMTS). Specifically, Long Term Evolution (LTE) is a version of UMTS using E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents provided by an organization named "3rd Generation Partnership Project" (3GPP), and cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies and standards are known or under development. For example, the 3rd Generation Partnership Project (3GPP) is a collaboration between telecommunication association groups with the goal of defining globally applicable third generation (3G) mobile phone specifications. 3GPP Long Term Evolution (LTE) is a 3GPP plan to improve the UMTS mobile phone standard. 3GPP may define specifications for next generation mobile networks, mobile systems, and mobile devices. The present disclosure relates to the evolution from LTE, 4G, 5G, NR and beyond wireless technologies, where access to the wireless spectrum is shared between networks using a range of new and different radio access technologies or radio air interfaces.

[0028] Specifically, 5G networks consider various deployments, various spectrums, and various services and devices that can be implemented using a unified air interface based on OFDM. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further enhancements to LTE and LTE-A are also considered. 5G NR will be able to scale to (1) ultra-high density (e.g., about 1M nodes / km) 2 (1) provide coverage for the massive Internet of Things (IoT) with ultra-low complexity (e.g., about 10s of bits / second), ultra-low energy (e.g., about 10+ years of battery life), and deep coverage with the ability to reach challenging locations; (2) provide coverage including mission-critical control with strong security to protect sensitive personal, financial, or classified information, ultra-high reliability (e.g., about 99.9999% reliability), ultra-low latency (e.g., about 1 millisecond), and for users with extensive mobility or lack of mobility; and (3) provide coverage with enhanced mobile broadband (including very high capacity (e.g., about 10Tbps / km 2 ), coverage of extremely high data rates (e.g., multi-Gbps rates, 100+Mbps user experience rates), and deep awareness with advanced discovery and optimization).

[0029] 5G NR can be implemented using an optimized OFDM-based waveform with scalable parameter sets and transmission time intervals (TTIs); with a common, flexible framework to efficiently multiplex services and features using dynamic low-latency time division duplex (TDD) / frequency division duplex (FDD) designs; and with advanced wireless technologies such as massive multiple-input multiple-output (MIMO), robust millimeter wave (mmWave) transmission, advanced channel decoding, and device-centric mobility. The scalability of parameter sets in 5G NR and the scaling of subcarrier spacing can effectively address the operation of various services across different spectrums and different deployments. For example, in various outdoor and macro coverage deployments of less than 3GHz FDD / TDD implementations, the subcarrier spacing may appear at 15kHz on bandwidths (BW) such as 5MHz, 10MHz, 20MHz, etc. For other various outdoor and small cell coverage deployments of TDD greater than 3GHz, the subcarrier spacing may appear at 30kHz on 80MHz / 100MHz BW. For various other indoor broadband implementations, using TDD on the unlicensed portion of the 5 GHz band, subcarrier spacing may occur at 60 kHz over 160 MHz BW. Finally, for various deployments transmitting with the mmWave component at 28 GHz TDD, subcarrier spacing may occur at 120 kHz over 500 MHz BW.

[0030] 5G NR's scalable parameter sets facilitate scalable TTIs for different latency and quality of service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmission to start on symbol boundaries. 5G NR also contemplates a self-contained integrated subframe design with uplink (UL) / downlink (DL) scheduling information, data, and acknowledgment in the same subframe. Self-contained integrated subframes support communications in unlicensed or contention-based shared spectrum, and support adaptive UL / DL that can be flexibly configured on a per-cell basis to dynamically switch between UL and DL to meet current traffic needs.

[0031] The various other aspects and features of the present disclosure are further described below. It should be apparent that the teachings herein can be embodied in various forms, and any specific structure, function, or both disclosed herein are merely representative and not restrictive. Based on the teachings herein, it should be understood by those of ordinary skill in the art that the aspects disclosed herein can be implemented independently of any other aspects, and two or more of these aspects can be combined in various ways. For example, any number of aspects set forth herein can be used to implement a device or practice a method. In addition, such a device can be implemented or such a method can be practiced using other structures, functionality, or structures and functionality other than or different from one or more aspects of the aspects set forth herein. For example, the method can be implemented as a part of a system, device, device, and / or implemented as an instruction stored on a computer-readable medium for execution on a processor or computer. In addition, one aspect can include at least one element of a claim.

[0032] Various aspects of the present disclosure allow UEs and / or network elements to address variability in the timing of XR traffic to improve network efficiency, network throughput, user experience, power consumption, processing requirements, etc. In some aspects, the start time and / or length of a periodic communication period (e.g., CDRX on duration, SPS opportunity, etc.) can be adjusted to better align with a data stream associated with XR or other communications. In some aspects, the UE receives an adjustment indication indicating at least one of a start time or a length of a connected discontinuous reception (CDRX) on duration; sends an acknowledgement (ACK) associated with the adjustment indication; and monitors communications based on at least one of a start time or a length of the CDRX on duration. In further aspects of the present disclosure, the UE monitors for an adjustment indication and / or a wake-up signal (WUS) during one or more monitoring opportunities associated with the CDRX on duration, and monitors communications associated with a data stream during the CDRX on duration based on a failure to receive a WUS during one or more monitoring opportunities, wherein the start time of the CDRX on duration is based on a nominal start time of the CDRX on duration and a maximum jitter of the data stream. In another aspect of the present disclosure, the UE receives an adjustment indication indicating at least one of a start time or a length of a semi-persistent scheduling (SPS) opportunity; sends an acknowledgment (ACK) associated with the adjustment indication; and monitors communications based on at least one of the start time or the length of the SPS opportunity.

[0033] Aspects of the present disclosure provide several advantages over existing methods and systems, including facilitating adjustment of the CDRX On Duration and / or the start time and / or length of SPS opportunities (and providing associated confirmation of such adjustments), which can improve network efficiency and / or throughput while also reducing power consumption, reducing processing requirements, and providing an improved user experience, among other benefits. These benefits are particularly present in the context of variable data streams (including XR data streams), but are also applicable to other types of communications.

[0034] Figure 1 A wireless communication network 100 according to one or more aspects of the present disclosure is illustrated. The network 100 may be a 5G network. The network 100 includes several BSs 105 (respectively labeled 105a, 105b, 105c, 105d, 105e, and 105f) and other network entities. The BS 105 may be a station that communicates with a UE 115 (respectively labeled 115a, 115b, 115c, 115d, 115e, 115f, 115g, 115h, and 115k), and may also be referred to as an evolved B node (eNB), a next generation eNB (gNB), an access point, etc. Each BS 105 may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the specific geographic coverage area of ​​the BS 105 and / or the BS subsystem serving the coverage area, depending on the context in which the term is used.

[0035] BS105 may provide communication coverage for macro cells or small cells (such as pico cells or femto cells) and / or other types of cells. Macro cells generally cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with a network provider. Small cells (such as pico cells) will generally cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions with a network provider. Small cells (such as femto cells) will generally also cover a relatively small geographic area (e.g., a home) and, in addition to unrestricted access, may also provide restricted access by UEs associated with the femto cells (e.g., UEs in a closed subscriber group (CSG), UEs of users in a home, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a small cell may be referred to as a small cell BS, a pico BS, a femto BS, or a home BS. In Figure 1In the embodiment, BS105d and 105e may be conventional macro BSs, while BS105a-105c may be macro BSs with one of three-dimensional (3D), full-dimensional (FD) or massive MIMO capabilities. BS105a-105c may utilize their higher-dimensional MIMO capabilities to employ 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. BS105f may be a small cell BS, which may be a home node or a portable access point. BS105 may support one or more (e.g., two, three, four, etc.) cells.

[0036] In some aspects, the term "base station" (e.g., base station 105) or "network entity" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station" or "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network entity" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with base station 105). In some aspects, the term "base station" or "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of several different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network entity" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network entity" may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network entity" may refer to one of the base station functions but not another base station function. In this way, a single device may include more than one base station.

[0037] Network 100 may support synchronous operation or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the BSs may have different frame timing, and transmissions from different BSs may not be aligned in time.

[0038] UE 115 is dispersed throughout the wireless network 100, and each UE 115 can be stationary or mobile. UE 115 may also be referred to as a terminal, a mobile station, a subscriber unit, a station, etc. UE 115 may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a wireless local loop (WLL) station, etc. In one aspect, UE 115 may be a device including a universal integrated circuit card (UICC). On the other hand, UE may be a device that does not include a UICC. In some aspects, UE 115 that does not include a UICC may also be referred to as an IoT device or an Internet of Everything (IoE) device. UE 115a-115d is an example of a mobile smart phone type device that accesses the network 100. UE 115 may also be a machine that is specifically configured for connected communications (including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc.). UE 115e-115h are examples of various machines configured for communication to access network 100. UE 115i-115k are examples of vehicles equipped with wireless communication devices configured for communication to access network 100. UE 115 may be able to communicate with any type of BS (whether macro BS, small cell, etc.). Figure 1 , a lightning symbol (e.g., a communication link) indicates wireless transmission between UE 115 and a serving BS 105 (which is a BS designated to provide service to UE 115 on DL and / or UL), desired transmission between BSs 105, backhaul transmission between BSs, or sidelink transmission between UEs 115.

[0039] In operation, BSs 105a-105c may use 3D beamforming and cooperative spatial techniques such as coordinated multipoint (CoMP) or multiple connections to serve UEs 115a and 115b. Macro BS 105d may perform backhaul communications with BSs 105a-105c and small cell BS 105f. Macro BS 105d may also transmit multicast services that UEs 115c and 115d subscribe to and receive. Such multicast services may include mobile TV or streaming video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber alerts or gray alerts.

[0040] The BS 105 may also communicate with a core network. The core network may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the BSs 105 (e.g., which may be instances of a gNB or access node controller (ANC)) may interface with the core network via a backhaul link (e.g., NG-C, NG-U, etc.) and may perform radio configuration and scheduling for communications with the UE 115. In various cases, the BSs 105 may communicate with each other directly or indirectly (e.g., via a core network) via a backhaul link (e.g., X1, X2, etc.), which may be a wired communication link or a wireless communication link.

[0041] The network 100 may also support mission-critical communications using ultra-reliable and redundant links for mission-critical devices such as UE 115e, which may be a drone. The redundant communication links with UE 115e may include links from macro BSs 105d and 105e, and links from small cell BS 105f. Other machine type devices such as UE 115f (e.g., a thermometer), UE 115g (e.g., a smart meter), and UE 115h (e.g., a wearable device) may communicate directly with BSs such as small cell BS 105f and macro BS 105e through the network 100, or communicate through the network in a multi-action size configuration by communicating with another user device such as UE 115f that communicates temperature measurement information to a smart meter (UE 115g), which then reports to the network through the small cell BS 105f, which relays its information to the network. The network 100 may also provide additional network efficiency through dynamic low latency TDD / FDD communications, such as V2V, V2X, C-V2X communications between UE 115i, 115j, or 115k and other UEs 115 and / or vehicle-to-infrastructure (V2I) communications between UE 115i, 115j, or 115k and BS 105.

[0042] In some implementations, the network 100 utilizes an OFDM-based waveform for communication. An OFDM-based system may divide the system BW into multiple (K) orthogonal subcarriers, which are also commonly referred to as subcarriers, tones, frequency bins, etc. Each subcarrier may be modulated with data. In some aspects, the subcarrier spacing between adjacent subcarriers may be fixed, and the total number of subcarriers (K) may depend on the system BW. The system BW may also be divided into subbands. In other aspects, the subcarrier spacing and / or the duration of the TTI may be scalable.

[0043] In some aspects, BS105 may assign or schedule transmission resources (e.g., in the form of time-frequency resource blocks (RBs)) for DL ​​and UL transmissions in network 100. DL refers to the transmission direction from BS105 to UE 115, and UL refers to the transmission direction from UE 115 to BS105. The communication may be in the form of a radio frame. A radio frame may be divided into a plurality of subframes or time slots, for example, about 10. Each time slot may also be divided into micro-time slots. In FDD mode, simultaneous UL transmission and DL transmission may occur in different frequency bands. For example, each subframe includes a UL subframe in a UL frequency band and a DL subframe in a DL frequency band. In TDD mode, UL transmission and DL transmission occur in different time periods using the same frequency band. For example, a subframe subset (e.g., a DL subframe) in a radio frame may be used for DL ​​transmission, and another subframe subset (e.g., an UL subframe) in a radio frame may be used for UL transmission.

[0044] DL subframes and UL subframes may also be divided into several zones. For example, each DL subframe or UL subframe may have a predefined zone for the transmission of reference signals, control information, and data. Reference signals are predetermined signals that facilitate communication between BS105 and UE 115. For example, a reference signal may have a specific pilot pattern or structure, wherein a pilot tone may span an operational BW or frequency band, and each pilot tone is located at a predefined time and a predefined frequency. For example, BS105 may send a cell-specific reference signal (CRS) and / or a channel state information-reference signal (CSI-RS) to enable UE 115 to estimate a DL channel. Similarly, UE 115 may send a sounding reference signal (SRS) to enable BS105 to estimate an UL channel. Control information may include resource assignments and protocol control. Data may include protocol data and / or operational data. In some aspects, BS105 and UE115 may communicate using self-contained subframes. Self-contained subframes may include a portion for DL ​​communication and a portion for UL communication. A self-contained subframe may be DL-centric or UL-centric. A DL-centric subframe may include a DL communication duration that is longer than a UL communication duration. A UL-centric subframe may include a UL communication duration that is longer than a DL communication duration.

[0045] In some aspects, network 100 may be an NR network deployed on a licensed spectrum. BS 105 may send synchronization signals (e.g., including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)) in network 100 to facilitate synchronization. BS 105 may broadcast system information associated with network 100 (e.g., including a master information block (MIB), remaining system information (RMSI), and other system information (OSI)) to facilitate initial network access. In some aspects, BS 105 may broadcast PSS, SSS, and / or MIB in the form of a synchronization signal block (SSB), and may broadcast RMSI and / or OSI on a physical downlink shared channel (PDSCH). MIB may be sent on a physical broadcast channel (PBCH).

[0046] In some aspects, a UE 115 attempting to access the network 100 may perform an initial cell search by detecting a PSS from the BS 105. The PSS may enable synchronization of period timing and may indicate a physical layer identification value. The UE 115 may then receive the SSS. The SSS may enable radio frame synchronization and may provide a cell identification value that may be combined with the physical layer identification value to identify a cell. The PSS and SSS may be located in the center portion of a carrier or at any suitable frequency within a carrier.

[0047] After receiving the PSS and SSS, the UE 115 may receive the MIB. The MIB may include system information for initial network access and scheduling information for RMSI and / or OSI. After decoding the MIB, the UE 115 may receive the RMSI and / or OSI. The RMSI and / or OSI may include radio resource control (RRC) information related to random access channel (RACH) procedures, paging, control resource sets (CORESET) for physical downlink control channel (PDCCH) monitoring, physical UL control channel (PUCCH), physical UL shared channel (PUSCH), power control, and SRS.

[0048] After obtaining the MIB, RMSI and / or OSI, the UE 115 may perform a random access procedure to establish a connection with the BS 105. In some instances, the random access procedure may be a four-step random access procedure. For example, the UE 115 may send a random access preamble, and the BS 105 may respond with a random access response. The random access response (RAR) may include a detected random access preamble identifier (ID) corresponding to the random access preamble, timing advance (TA) information, UL authorization, a temporary cell radio network temporary identifier (C-RNTI), and / or a backoff indicator. Upon receiving the random access response, the UE 115 may send a connection request to the BS 105 and the BS 105 may respond with a connection response. The connection response may indicate contention resolution. In some instances, the random access preamble, the RAR, the connection request, and the connection response may be referred to as message 1 (MSG1), message 2 (MSG2), message 3 (MSG3), and message 4 (MSG4), respectively. In some examples, the random access process may be a two-step random access procedure, where the UE 115 may send a random access preamble and a connection request in a single transmission, and the BS 105 may respond by sending a random access response and a connection response in a single transmission.

[0049] After establishing the connection, UE 115 and BS 105 may enter a normal operation phase, in which operational data may be exchanged. For example, BS 105 may schedule UE 115 to perform UL and / or DL ​​communications. BS 105 may send UL scheduling grants and / or DL ​​scheduling grants to UE 115 via PDCCH. Scheduling grants may be sent in the form of DL control information (DCI). BS 105 may send DL communication signals (e.g., carrying data) to UE 115 via PDSCH according to the DL scheduling grant. UE 115 may send UL communication signals to BS 105 via PUSCH and / or PUCCH according to the UL scheduling grant. The connection may be referred to as an RRC connection. When UE 115 actively exchanges data with BS 105, UE 115 is in an RRC connection state.

[0050] In some aspects, after establishing a connection with BS 105, UE 115 may initiate an initial network attachment procedure with network 100. BS 105 may coordinate with various network entities or fifth generation core (5GC) entities, such as access and mobility function (AMF), serving gateway (SGW) and / or packet data network gateway (PGW) to complete the network attachment procedure. For example, BS 105 may coordinate with network entities in 5GC to identify UE, authenticate UE and / or authorize UE to transmit and / or receive data in network 100. In addition, AMF may assign a set of tracking areas (TAs) to UE. Once the network attachment procedure is successful, a context is established in AMF for UE 115. After successfully attaching to the network, UE 115 may move around the current TA. For tracking area update (TAU), BS 105 may request UE 115 to periodically update network 100 with the location of UE 115. Alternatively, UE 115 may report the location of UE 115 to network 100 only when entering a new TA. The TAU allows the network 100 to quickly locate and page the UE 115 when an incoming data packet or call for the UE 115 is received.

[0051] In some aspects, BS105 may communicate with UE 115 using HARQ technology to improve communication reliability, for example, to provide URLLC services. BS105 may schedule UE 115 to perform PDSCH communication by sending DL grants in PDCCH. BS105 may send DL data packets to UE 115 according to the scheduling in PDSCH. DL data packets may be sent in the form of transport blocks (TBs). After receiving the DL data packets, UE 115 may send a feedback message for the DL data packets to BS105. In some instances, UE 115 may send feedback on confirmation resources. The feedback may be an acknowledgment (ACK) indicating that UE 115 successfully receives the DL data packets (e.g., DL data is received without error) or may be a negative acknowledgment (NACK) indicating that UE 115 does not successfully receive the DL data packets (e.g., including errors or error correction failures). In some aspects, if UE 115 successfully receives the DL data packets, UE 115 may send HARQ ACK to BS105. Conversely, if the UE 115 fails to successfully receive the DL transmission, the UE 115 may send a HARQ NACK to the BS 105. Upon receiving the HARQ NACK from the UE 115, the BS 105 may retransmit the DL data packet to the UE 115. The retransmission may include a decoded version of the DL data that is the same as the initial transmission. Alternatively, the retransmission may include a decoded version of the DL data that is different from the initial transmission. The UE 115 may apply soft combining to combine the coded data received from the initial transmission and the retransmission for decoding. The BS 105 and the UE 115 may also apply HARQ to UL communications using a mechanism substantially similar to DL HARQ.

[0052] In some aspects, the network 100 may operate on a system BW or a component carrier (CC) BW. The network 100 may divide the system BW into multiple BWPs (e.g., parts). The BS 105 may dynamically assign the UE 115 to operate on a specific BWP (e.g., a specific part of the system BW). The assigned BWP may be referred to as an active BWP. The UE 115 may monitor the active BWP to find signaling information from the BS 105. The BS 105 may schedule the UE 115 to perform UL or DL ​​communications in the active BWP. In some aspects, the BS 105 may assign a pair of BWPs within the CC to the UE 115 for UL and DL communications. For example, the BWP pair may include a BWP for UL communication and a BWP for DL ​​communication.

[0053] The deployment of a communication system (such as a 5G New Radio (NR) system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element or a network equipment (such as a base station (BS), or one or more units (or one or more components) that perform base station functionality can be implemented in an aggregated architecture or a decomposed architecture. For example, a BS (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmit receive point (TRP) or a cell, etc.) can be implemented as an aggregated base station (also referred to as an independent BS or a monolithic BS) or a decomposed base station.

[0054] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack physically or logically distributed between two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0055] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (network configurations such as those initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0056] Figure 2A diagram illustrating an example decomposed base station 200 architecture is shown. The decomposed base station 200 architecture may include one or more central units (CUs) 210 that may communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a service management and orchestration (SMO) framework 205, or both. The CU 210 may communicate with one or more distributed units (DUs) 230 via respective midhaul links, such as an F1 interface. The DU 230 may communicate with one or more radio units (RUs) 240 via respective fronthaul links. The RU 240 may communicate with respective UEs 120 via one or more radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 240.

[0057] Each of these units (i.e., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO framework 205) may include one or more interfaces, or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of these units or an associated processor or controller that provides instructions to the communication interface of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface that is configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as a radio frequency (RF) transceiver) that is configured to receive or send signals, or both, to one or more of the other units on a wireless transmission medium.

[0058] In some aspects, CU 210 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 210. CU 210 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 210 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 210 may be implemented to communicate with DU 230 for network control and signaling.

[0059] DU 230 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 240. In some aspects, DU 230 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to functional divisions such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0060] The lower layer functionality may be implemented by one or more RUs 240. In some deployments, a RU 240 controlled by a DU 230 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional partitioning (such as a lower layer functional partitioning). In such an architecture, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control plane communications and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable the DU 230 and CU 210 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0061] The SMO framework 205 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some specific implementations, the SMO framework 205 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 211) via the O1 interface. In addition, in some specific implementations, the SMO framework 205 may communicate directly with one or more RUs 240 via the O1 interface. The SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of the SMO framework 205 .

[0062] The non-RT RIC 215 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 225. The non-RT RIC 215 may be coupled to or in communication with the near-RT RIC 225 (such as via an A1 interface). The near-RT RIC 225 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 210, one or more DUs 230, or both, and the O-eNB with the near-RT RIC 225.

[0063] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 225 and may be received from a non-network data source or from a network function at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 205 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0064] Figure 3 Examples of extended reality (XR) devices according to some aspects of the present disclosure are illustrated. In particular, Figure 3 The XR device 300 illustrated in the example includes (1) an AR and / or MR smartphone, tablet, or portable console 115m; (2) an AR, MR, and / or VR wearable system including a smartphone, tablet, or portable console and a mounting structure (e.g., a headband configured to receive the smartphone, tablet, or portable console and / or to couple with the smartphone, tablet, or portable console) 115n; (3) AR and / or MR smart glasses 115o; and (4) VR goggles 115p. In some instances, the XR device 300 is a UE (e.g., UE 115 and / or UE 1000). It should be understood that aspects of the present disclosure as a whole are applicable to any type of XR device (not just a headband). Figure 3 ). Further, it should be understood that each of the XR devices 300 can be tethered to other devices including a smartphone, a personal computer (PC), or a console. Thus, the XR device can be connected to another device using a universal serial bus (USB) link, a Bluetooth link, a Wi-Fi link, a 5G side link, or other suitable connection. In some instances, the XR device receives downlink data from a server, a host, or other device through the device to which the XR device is tethered. Therefore, it should be understood that aspects of the present disclosure are applicable to use with an XR device alone and / or tethered to one or more other devices through which the XR device receives data.

[0065] Figure 4 A wireless communication scheme 400 according to some aspects of the present disclosure is illustrated. The wireless communication scheme 400 includes multiple XR data streams, including XR stream 1 405a and XR stream 2 405b. Figure 4 Two XR data streams are shown, but the present disclosure is applicable to non-XR data communications as well as a single XR data stream and more than two XR data streams.

[0066] The XR data stream may have variability in the number and / or size of packets per data burst. Further, the XR data stream may be based on a non-integer time period (e.g., 60 frames per second is equivalent to a time period of approximately 16.67 ms; 120 frames per second is equivalent to a time period of approximately 8.33 ms). Still further, the arrival time of the XR traffic may vary (e.g., jitter between -4 ms and +4 ms or other values ​​may be observed). Moreover, when multiple XR data streams are active, one or more of the XR data streams may have a different configuration than another XR data stream in the XR data stream. The XR data stream may also be affected by a packet delay budget that affects the scheduling and / or latency of the communication. XR stream 1 405a and XR stream 2 405b illustrate some of these aspects of the XR data stream.

[0067] As shown, XR stream 1 405a may be associated with a periodic communication scheme (e.g., CDRX, SPS, etc.) having a period 410a. Period 410a may be an integer time period (e.g., 5ms, 10ms, 20ms, etc.) or a non-integer time period (e.g., approximately 8.33ms, approximately 16.67ms, etc.). Based on period 410a, XR stream 1 405a may have a nominal start time 415a. Nominal start time 415a is separated in time by period 410a.

[0068] XR stream 1 405a may include a first data burst 420a, which includes one or more data packets and / or transport blocks. In the illustrated example, the first data burst 420a includes three packets and / or transport blocks of varying sizes, but it should be understood that the first data burst 420a may include any number of packets and / or transport blocks of the same or different sizes. The start time 425a of the first data burst 420a may be offset from the nominal start time 415a by an offset 430a. In some instances, the offset 430a may be the result of jitter and / or other factors that affect the transmission and / or arrival time of the first data burst 420a. In the illustrated example, the start time 425a of the first data burst 420a is delayed (i.e., later in time) relative to the nominal start time 415a.

[0069] XR stream 1 405a may include a second data burst 440a, which includes one or more data packets and / or transport blocks. In the illustrated example, the second data burst 440a includes two packets and / or transport blocks of varying sizes, but it should be understood that the second data burst 440a may include any number of packets and / or transport blocks of the same or different sizes. The start time 445a of the second data burst 440a may be offset 450a from the nominal start time 415a. In some instances, the offset 450a may be the result of jitter and / or other factors that affect the transmission and / or arrival time of the second data burst 440a. In the illustrated example, the start time 445a of the second data burst 440a is earlier relative to the nominal start time 415a (i.e., earlier in time than the nominal start time).

[0070] As also shown, XR stream 2 405b may be associated with a periodic communication scheme (e.g., CDRX, SPS, etc.) having a period 410b. Period 410b may be the same or different from period 410a of XR stream 1 405a. In the illustrated example, period 410b is shorter than period 410a. Period 410b may be an integer time period (e.g., 5ms, 10ms, 20ms, etc.) or a non-integer time period (e.g., about 8.33ms, about 16.67ms, etc.). Based on period 410b, XR stream 2 405b may have a nominal start time 415b. Nominal start time 415b is separated in time by period 410b.

[0071] XR stream 2 405b may include a first data burst 420b, which includes one or more data packets and / or transport blocks. In the illustrated example, the first data burst 420b includes two packets and / or transport blocks of varying sizes, but it should be understood that the first data burst 420b may include any number of packets and / or transport blocks of the same or different sizes. The start time 425b of the first data burst 420b may be offset from the nominal start time 415b by an offset 430b. In some instances, the offset 430b may be the result of jitter and / or other factors that affect the transmission and / or arrival time of the first data burst 420b. In the illustrated example, the start time 425b of the first data burst 420b is earlier relative to the nominal start time 415b (i.e., earlier in time than the nominal start time).

[0072] XR stream 2 405b may include a second data burst 440b, which includes one or more data packets and / or transport blocks. In the illustrated example, the second data burst 440b includes two packets and / or transport blocks of varying sizes, but it should be understood that the second data burst 440b may include any number of packets and / or transport blocks of the same or different sizes. The start time 445b of the second data burst 440b may be offset 450b from the nominal start time 415b. In some instances, the offset 450b may be the result of jitter and / or other factors that affect the transmission and / or arrival time of the second data burst 440b. In the illustrated example, the start time 445b of the second data burst 440a is delayed (i.e., later in time) relative to the nominal start time 415a.

[0073] Aspects of the present disclosure allow UEs and / or network elements to account for variability in the timing of XR traffic. In some aspects, the start time and / or length of periodic communication periods (e.g., CDRX on duration, SPS opportunities, etc.) can be adjusted to better align with data streams associated with XR or other communications.

[0074] Figure 5 A wireless communication scheme 500 according to one or more aspects of the present disclosure is illustrated. The wireless communication scheme 500 includes monitoring opportunities 505a, 505b, and 505c, acknowledgment (ACK) resources 510a, 510b, and 510c, a nominal start time 515, CDRX on durations 520a, 520b, and 520c, an adjusted start time 525, and CDRX off durations 530a, 530b, and 530c. In this regard, ACK resources 510a, 510b, and 510c may be associated with monitoring opportunities 505a, 505b, and 505c, respectively (e.g., ACK resource 510a may be associated with monitoring opportunity 505a, ACK resource 510b may be associated with monitoring opportunity 505b, ACK resource 510c may be associated with monitoring opportunity 505c, and so on). Although Figure 5 Three monitoring opportunities 505a, 505b, and 505c are illustrated, but it will be appreciated that any suitable number of monitoring opportunities may be utilized, including fewer (eg, 1 or 2) or more (4, 5, 6, etc.).

[0075] A UE (e.g., UE 115 or UE 1000) may receive a configuration or other communication indicating the location (e.g., time resources and / or frequency resources) of one or more monitoring opportunities 505a, 505b, and 505c from a network element. The monitoring opportunities 505a, 505b, and 505c may occupy physical downlink control channel (PDCCH) resources and / or physical downlink shared channel (PDSCH) resources. The UE may monitor the monitoring opportunities 505a, 505b, and 505c for an adjustment indication, which indicates at least one of the start time of a connected discontinuous reception (CDRX) on duration (e.g., CDRX on duration 520a, 520b, and 520c) and / or the length of the CDRX on duration (e.g., CDRX on duration 520a, 520b, and 520c). In some aspects, the adjustment indication may additionally indicate to the UE whether to wake up at the next CDRX on duration. The adjustment indication may be UE-specific or for a group of UEs including the UE. Thus, the UE may monitor UE-specific communications during a monitoring occasion or monitor group-common communications for a UE group to which the UE belongs.

[0076] By monitoring monitoring opportunities 505a, 505b, and 505c, the UE may receive an adjustment indication. In some instances, the UE may expect to receive only a single adjustment indication during one or more monitoring opportunities associated with the CDRX on duration. Based on which monitoring opportunity (e.g., monitoring opportunity 505a, 505b, or 505c) the UE receives the adjustment indication, the UE may use the associated ACK resource (e.g., ACK resource 510a, 510b, or 510c) to send an ACK. In some instances, the UE uses a PUCCH resource of PUCCH format 0 or PUCCH format 1 to send an ACK. In some instances, the UE sends an ACK based on a HARQ process associated with the resource in which the adjustment indication is received. In response to receiving an adjustment indication from a network unit (e.g., network unit 1100, BS105, CU 210, DU 230, and / or RU 240), the UE may send an ACK to the network unit. The UE may receive an adjustment indication from a network element via a physical downlink control channel (PDCCH) communication and / or a physical downlink shared channel (PDSCH) communication. For example, in some instances, the UE may receive an adjustment indication from a network element via a PDCCH, via downlink control information (DCI). The DCI may be a group common DCI or a UE-specific DCI. In some aspects, the adjustment indication may have a format that is the same and / or similar to a wake-up signal (WUS). In some instances, the WUS includes an adjustment indication. In some instances, the UE may receive an adjustment indication from a network element via a PDSCH, via a medium access control control element (MAC-CE). In some aspects, the PDSCH communication may include a MAC-CE, which includes an adjustment indication.

[0077] The adjustment indication may indicate the start time of the CDRX on duration and / or the length of the CDRX on duration in any suitable manner. In some aspects, the adjustment indication indicates that the nominal start time 515 is unchanged (e.g., as described with respect to Figure 5520a and 520c in the CDRX on duration). In some aspects, the adjustment indication indicates a change to the nominal start time 515. For example, in some instances, the adjustment indication may indicate an adjusted start time 525 of the CDRX on duration 520b, as shown. The adjusted start time 525 may be indicated as a timing offset relative to the nominal start time 515. The timing offset may be indicated in symbols, sub-slots, time slots, milliseconds, microseconds, or other suitable units of measurement. Further, the timing offset may be relative to the nominal start time 515 of the CDRX on duration, the reception time of the adjustment indication (e.g., the monitoring opportunity 505a, 505b, or 505c at which the adjustment indication is received), and / or the transmission time of an acknowledgment (ACK) associated with the adjustment indication (e.g., the ACK resource 510a, 510b, 510c in which the ACK is sent).

[0078] In some aspects, the adjustment indication indicates the length of the CDRX On Duration. The length of the CDRX On Duration may be indicated in symbols, sub-slots, time slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the length of the CDRX On Duration may be indicated in terms of an actual length and / or a relative length. For example, in some instances, the length of the CDRX On Duration may be indicated relative to a nominal length of the CDRX On Duration. In some aspects, the adjustment indication indicates that the nominal length of the CDRX On Duration has not changed (e.g., as described with respect to FIG. 1 ). Figure 5 In some aspects, the adjustment indication indicates a change to the nominal length of the CDRX On Duration (e.g., as shown in FIG. 5 ). Figure 5 , which has been extended relative to the nominal length). In some aspects, the adjustment indicates a ratio of the nominal length of the CDRX On Duration (eg, twice, half, etc., the nominal length).

[0079] The UE may monitor communications (e.g., one or more PDSCH communications, PDCCH communications, and / or other communications, which may include data bursts (e.g., XR data bursts 420a, 420b, 440a, 440b) associated with a data stream (e.g., XR stream 1 405a and / or XR stream 2 405b)) based on the start time of the CDRX on duration and / or the length of the CDRX on duration indicated by the adjustment indication. For example, when the adjustment indication includes an indication of the start time of the CDRX on duration (e.g., drx-SlotOffset), the UE may begin monitoring communications based on the start time of the CDRX on duration as indicated by the adjustment indication, which start time may be the same as the nominal start time of the CDRX on duration (e.g., as shown in CDRX on durations 520a and 520c) or offset from the nominal start time of the CDRX on duration (e.g., as shown in CDRX on durations 520b). Similarly, when the adjustment indication includes an indication of the length of the CDRX On Duration, the UE may monitor communications based on the length of the CDRX On Duration as indicated by the adjustment indication, which may be the same as the nominal length of the CDRX On Duration (e.g., as shown in CDRX On Duration 520a and 520b) or different from the nominal length of the CDRX On Duration (e.g., as shown in CDRX On Duration 520c). For example, the UE may set a CDRX On Duration timer (e.g., drx-onDurationTimer) corresponding to the CDRX On Duration indicated by the length. Further, when the adjustment indication includes an indication of both the start time and the length of the CDRX On Duration, the UE may start monitoring communications based on the start time of the CDRX On Duration as indicated by the adjustment indication, and monitor communications based on the length of the CDRX On Duration as indicated by the adjustment indication. When the adjustment indication includes an indication of the length of the CDRX On Duration but does not indicate the start time of the CDRX On Duration, the UE may start monitoring communications at the nominal start time 515 of the CDRX On Duration.

[0080] Figure 6A wireless communication scheme 600 is illustrated in accordance with one or more aspects of the present disclosure. In some aspects, the wireless communication scheme 600 may be similar to the wireless communication scheme 500, however, the wireless communication scheme 600 may be associated with a semi-persistent scheduling (SPS) rather than a CDRX cycle. The communication scheme 600 includes monitoring opportunities 605a and 605b, acknowledgment (ACK) resources 610a and 510b, a nominal start time 615, an SPS opportunity 620, and an adjusted start time 625. In this regard, the ACK resources 610a and 610b may be associated with the monitoring opportunities 605a and 605b, respectively (e.g., the ACK resource 610a may be associated with the monitoring opportunity 605a, and the ACK resource 610b may be associated with the monitoring opportunity 605b, and so on). Although Figure 6 Two monitoring opportunities 605a and 605b are illustrated, but it will be appreciated that any suitable number of monitoring opportunities may be utilized, including fewer (eg, 1) or more (3, 4, 5, 6, etc.).

[0081] A UE (e.g., UE 115 or UE 1000) may receive a configuration or other communication indicating the location (e.g., time resources and / or frequency resources) of one or more monitoring opportunities 605a and 605b from a network element. The monitoring opportunities 605a and 605b may occupy physical downlink control channel (PDCCH) resources and / or physical downlink shared channel (PDSCH) resources. The UE may monitor the monitoring opportunities 605a and 605b for an adjustment indication indicating at least one of the start time of the SPS opportunity 620 and / or the length of the SPS opportunity 620. The adjustment indication may be UE-specific or for a group of UEs including the UE. Thus, the UE may monitor UE-specific communications during the monitoring opportunity or monitor group common communications for the UE group to which the UE belongs.

[0082] By monitoring monitoring opportunities 605a and 605b, the UE may receive an adjustment indication. In some instances, the UE may expect to receive only a single adjustment indication during one or more monitoring opportunities associated with the SPS opportunity. Based on which monitoring opportunity (e.g., monitoring opportunity 605a or 605b) the UE receives the adjustment indication, the UE may use the associated ACK resource (e.g., ACK resource 610a or 610b) to send an ACK. In some instances, the UE sends an ACK based on the HARQ process associated with the resource in which the adjustment indication is received. The UE may receive an adjustment indication from a network element (e.g., network element 1100, BS105, CU 210, DU 230, and / or RU 240) and / or send an ACK to the network element. The UE may receive an adjustment indication from a network element via a physical downlink control channel (PDCCH) communication and / or a physical downlink shared channel (PDSCH) communication. For example, in some instances, the UE may receive an adjustment indication from a network element via a PDCCH, via downlink control information (DCI). The DCI may be a group common DCI or a UE specific DCI. In some aspects, the adjustment indication may have the same and / or similar format as a wake-up signal (WUS). In some instances, the WUS includes the adjustment indication. In some instances, the UE may receive the adjustment indication from a network element via a PDSCH, via a medium access control control element (MAC-CE). In some aspects, the PDSCH communication may include a MAC-CE, which includes the adjustment indication.

[0083] The adjustment indication may indicate the start time of the SPS opportunity 620 and / or the length of the SPS opportunity 620 in any suitable manner. In some aspects, the adjustment indication indicates that the nominal start time 615 has not changed. In some aspects, the adjustment indication indicates a change to the nominal start time 615. For example, in some instances, the adjustment indication may indicate an adjusted start time 625 of the SPS opportunity 620, as shown. The adjusted start time 625 may be indicated as a timing offset relative to the nominal start time 615. The timing offset may be indicated in symbols, subslots, slots, milliseconds, microseconds, or other suitable units of measurement. Further, the timing offset may be relative to the nominal start time 615 of the SPS opportunity 620, the reception time of the adjustment indication (e.g., the monitoring opportunity 605a or 605b at which the adjustment indication is received) and / or the transmission time of the confirmation (ACK) associated with the adjustment indication (e.g., the ACK resource 610a or 610b in which the ACK is sent).

[0084] In some aspects, the adjustment indication indicates the length of the SPS opportunity 620. The length of the SPS opportunity 620 may be indicated in symbols, sub-slots, time slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the length of the SPS opportunity 620 may be indicated according to an actual length and / or a relative length. For example, in some instances, the length of the SPS opportunity 620 may be indicated relative to the nominal length of the SPS opportunity 620. In some aspects, the adjustment indication indicates that the nominal length of the SPS opportunity 620 has not changed. In some aspects, the adjustment indication indicates a change to the nominal length of the SPS opportunity 620.

[0085] The UE may monitor communications (e.g., one or more PDSCH communications, PDCCH communications, and / or other communications, which may include data bursts (e.g., XR data bursts 420a, 420b, 440a, 440b) associated with a data stream (e.g., XR stream 1 405a and / or XR stream 2 405b)) based on the start time of the SPS opportunity 620 indicated by the adjustment indication and / or the length of the SPS opportunity 620. For example, when the adjustment indication includes an indication of the start time of the SPS opportunity 620, the UE may begin monitoring communications based on the start time of the SPS opportunity 620 as indicated by the adjustment indication, which start time may be the same as the nominal start time 615 of the SPS opportunity 620 or offset from the nominal start time 615 of the SPS opportunity (e.g., as Figure 6 ). Similarly, when the adjustment indication includes an indication of the length of the SPS opportunity 620, the UE may monitor communications based on the length of the SPS opportunity 620 as indicated by the adjustment indication, which may be the same as the nominal length of the SPS opportunity 620 or different from the nominal length of the SPS opportunity 620. Further, when the adjustment indication includes an indication of both the start time and the length of the SPS opportunity 620, the UE may begin monitoring communications based on the start time of the SPS opportunity 620 as indicated by the adjustment indication, and monitor communications based on the length of the SPS opportunity 620 as indicated by the adjustment indication. When the adjustment indication includes an indication of the length of the SPS opportunity 620 but does not indicate the start time of the SPS opportunity 620, the UE may begin monitoring communications at the nominal start time 615 of the SPS opportunity 620.

[0086] Figure 7 A wireless communication scheme 700 is illustrated in accordance with one or more aspects of the present disclosure. In some aspects, the wireless communication scheme 700 may include aspects similar to the wireless communication schemes 500 and 600 described above. In this regard, Figure 7 The same reference numerals are used in the context of Figure 5 The invention also relates to features that are the same or similar to those described for wireless communication scheme 500, and therefore these descriptions will not be repeated here. It should also be understood that in the context of CDRX, reference to Figure 7 The concepts described apply similarly to the SPS scenario.

[0087] Again, the UE may monitor monitoring opportunities 505a, 505b, and 505c for adjustment indications. However, in contrast to the wireless communication scheme 500, regardless of which monitoring opportunity (e.g., monitoring opportunity 505a, 505b, or 505c) the UE receives the adjustment indication, the UE uses the common ACK resource 510 to send the ACK. That is, if the UE receives the adjustment indication during any one of the monitoring opportunities 505a, 505b, or 505c, the UE uses the common ACK resource 510 to send the ACK. In some instances, the common ACK resource 510 is spaced apart from the last monitoring opportunity (e.g., monitoring opportunity 505c) by a time offset 705. In some instances, the time offset 705 may be a fixed offset (e.g., a time slot number such as K0 or K1 indicated by the DCI). In some instances, the position and or time offset 705 of the ACK resource 510 may be selected to ensure that the ACK resource 510 occupies resources intended for uplink communication. For example, the position of the ACK resource 510 may be a valid uplink time slot (as opposed to a valid downlink time slot). In some instances, the public ACK source 510 may be ahead of the CDRX start time by a time offset 705, wherein the CDRX start time may be a nominal start time or an indicated start time. In some instances, the public ACK source 510 may be later than the CDRX start time by a time offset 705, wherein the CDRX start time may be a nominal start time or an indicated start time. In some instances, the public ACK resource 510 is in the first uplink time slot after the start time of the CDRX start time. In some instances, the time offset 705 may be a fixed offset (e.g., a time slot number such as K0 or K1 indicated by the DCI). In some instances, the position and / or time offset 705 of the ACK resource 510 may be selected to ensure that the ACK resource 510 occupies resources intended for uplink communication. In some instances, the UE receives an indication of the time offset 705 from the network element. In some instances, the time offset 705 may be indicated in the same communication that indicates the location (eg, time resources and / or frequency resources) of one or more monitoring opportunities 505a, 505b, and 505c. In some instances, the time offset 705 may be indicated to the UE in a separate communication.

[0088] As discussed above, the adjustment indication may indicate the start time of the CDRX On-Duration in any suitable manner. Figure 7The wireless communication scheme 700 of the embodiment of the present invention illustrates some of the options for indicating the start time of the CDRX on duration 520. In some aspects, the adjustment indication indicates that the nominal start time 515 has not changed. In some aspects, the adjustment indication indicates a change to the nominal start time 515. For example, in some instances, the adjustment indication may indicate an adjusted start time 525 for the CDRX on duration 520, as shown. The adjusted start time 525 may be indicated as a timing offset. The timing offset may be indicated in symbols, subslots, slots, milliseconds, microseconds, or other suitable units of measurement. Further, the timing offset may be relative to the nominal start time 515 of the CDRX on duration 520, as shown in the timing offset 710. The timing may also be relative to the reception time of the adjustment indication (e.g., the monitoring opportunity 505b at which the adjustment indication is received), as shown in the timing offset 715. The timing may also be relative to the transmission time of the ACK associated with the adjustment indication (e.g., the ACK resource 510 in which the ACK is transmitted).

[0089] Figure 8 A wireless communication scheme 800 is illustrated in accordance with one or more aspects of the present disclosure. In some aspects, the wireless communication scheme 800 may include aspects similar to the wireless communication schemes 500, 600, and 700 described above. In this regard, Figure 8 The same reference numerals are used in the context of Figure 5 The present invention also relates to features that are the same or similar to those described for the wireless communication scheme 500 , and therefore those descriptions will not be repeated here.

[0090] As discussed above, a UE (e.g., UE 115 or UE 1000) may receive a configuration or other communication indicating the location (e.g., time resources and / or frequency resources) of one or more monitoring opportunities from a network element. The monitoring opportunity may occupy physical downlink control channel (PDCCH) resources and / or physical downlink shared channel (PDSCH) resources. In some aspects, the monitoring opportunity includes one or more SPS opportunities (e.g., SPS opportunity 805). In some instances, one or more SPS opportunities are associated with a CDRX cycle. For example, one or more SPS opportunities may occur before the CDRX on duration 520 (e.g., before the nominal start time 515 of the CDRX on duration). In this way, the SPS opportunity may be used to convey an adjustment indication. The UE may monitor the SPS opportunity 805 for an adjustment indication indicating at least one of the start time of the CDRX on duration 520 and / or the length of the CDRX on duration 520.

[0091] By monitoring the SPS opportunity 805, the UE may receive an adjustment indication. The UE may use the associated ACK resource 810 to send an ACK. The ACK resource 810 may be associated with a single SPS opportunity (e.g., similar to Figure 5 ) and / or multiple SPS opportunities (e.g., similar to Figure 7 ). In some instances, the UE may receive an adjustment indication from a network element via a medium access control control element (MAC-CE) via a PDSCH communication of an SPS opportunity 805. In some instances, the adjustment indication carried by the MAC-CE indicates at least one of a timing offset for the start of a CDRX on duration 520 (e.g., indicating an adjusted start time 525) and / or a length of the CDRX on duration 520. In some instances, the PDSCH communication may be associated with the SPS opportunity 805. In this regard, in some aspects, the PDSCH communication of the SPS opportunity 805 may include a MAC-CE carrying an adjustment indication, and the adjustment indication may include an indication of a start time of a CDRX on duration 520 for a CDRX cycle associated with the SPS opportunity 805. In some instances, the UE receives the adjustment indication by monitoring the PDSCH for the adjustment indication during one or more scheduled downlink communication opportunities (which may include an SPS opportunity (e.g., the SPS opportunity 805)).

[0092] Fig. 9 A wireless communication scheme 900 is illustrated in accordance with one or more aspects of the present disclosure. In some aspects, the wireless communication scheme 900 may include aspects similar to the wireless communication schemes 500, 600, 700, and 800 described above. In this regard, Fig. 9 The same reference numerals are used in the context of Figure 5 The wireless communication scheme 900 may be used in combination with aspects of the wireless communication schemes 500, 600, 700, and 800. It should also be understood that the description of the wireless communication scheme 900 in the context of CDRX is the same as or similar to the features described in the wireless communication scheme 500, and therefore these descriptions will not be repeated here. In some examples, the wireless communication scheme 900 may be used in combination with aspects of the wireless communication schemes 500, 600, 700, and 800. Fig. 9 The concepts described apply similarly to the SPS scenario.

[0093] The UE may monitor the adjustment indication and / or the wake-up signal during one or more monitoring opportunities (e.g., monitoring opportunities 505a, 505b, and 505c) associated with the CDRX on duration (e.g., CDRX on duration 520). As shown, in the wireless communication scheme 900, the UE does not receive the adjustment indication / WUS in any of the monitoring opportunities 505a, 505b, and 505c (as indicated by an "X" in each of the monitoring opportunities 505a, 505b, and 505c).

[0094] Based on a failure to receive an adjustment indication / WUS during one or more monitoring opportunities 505a, 505b, or 505c, the UE may monitor communications associated with the data stream during the CDRX On Duration. The UE may monitor communications using an adjusted start time 525 of the CDRX On Duration based on the nominal start time 515 of the CDRX On Duration and the jitter of the data stream (e.g., maximum jitter, median jitter, average jitter, etc.). That is, the UE may determine the adjusted start time 525 of the CDRX On Duration 520 by adjusting the nominal start time 515 of the CDRX On Duration 520 based on the maximum jitter of the data stream, as indicated by the offset 910. That is, the UE may adjust the nominal start time 515 by the offset 910 to arrive at the adjusted start time 525, which may be before the nominal start time (e.g., Fig. 9 525) and / or after the nominal start time. For example, in some instances, the UE may determine an adjusted start time 525 of the CDRX On Duration 520 by adding or subtracting a time relative to the nominal start time 515 of the CDRX On Duration based on the maximum jitter of the data stream. Thus, the determined adjusted start time may be the same as the nominal start time (e.g., when the data stream has no jitter or has minimal jitter) or offset from the nominal start time (e.g., when the data stream has jitter). The UE may begin monitoring for communications from the determined start time (e.g., the adjusted start time 525) of the CDRX On Duration 520.

[0095] In some aspects, the UE may receive an indication of jitter (e.g., maximum jitter, median jitter, average jitter, etc.) of the data stream. The UE may receive the indication of jitter from the network element. The indication of jitter may be an explicit indication or an implicit indication. For example, the UE may receive an explicit indication of jitter (e.g., maximum jitter measurement, median jitter measurement, average jitter measurement, etc.) from the network element. The network element may provide an explicit indication of jitter to the UE to allow the UE to adjust the nominal start time 515 of one or more CDRX on durations when no adjustment indication is provided and / or for other communication purposes. In some aspects, the UE may determine a jitter parameter and / or an associated offset 910 using information about jitter received by one or more higher layers of the UE, which is used to adjust the nominal start time 515 of the CDRX on duration 520. In some instances, the indication of jitter may be an implicit indication. For example, the UE may receive an indication of one or more higher layer parameters associated with the communication flow from the network element, which may be used by the UE to determine a jitter parameter and / or an associated offset 910 for adjusting the start time of the CDRX On Duration 520. The UE may receive explicit and / or implicit indications of jitter via RRC communications, PDCCH communications, PDSCH communications, and / or other suitable communications.

In one aspect, the memory 1004 includes a non-transitory computer-readable medium. The memory 1004 may store or have recorded thereon instructions 1006. The instructions 1006 may include instructions that, when executed by the processor 1002, cause the processor 1002 to perform operations in conjunction with various aspects of the present disclosure (e.g., Figures 4 to 9 , Fig.12 and Fig.14 Instructions 1006 may also be referred to as code, which may be broadly interpreted as including the above-mentioned instructions for the operation described with reference to UE 115. Figures 4 to 9 , Fig.12 and Fig.14 Any type of computer-readable statement in question.

For example, the CDRX and / or SPS module 1008 may be implemented as a processor, circuit, and / or instructions 1006 stored in the memory 1004 and executed by the processor 1002. In some aspects, the CDRX and / or SPS module 1008 may be integrated within the modem subsystem 1012. For example, the CDRX and / or SPS module 1008 may be implemented by a combination of software components (e.g., executed by a DSP or general purpose processor) and hardware components (e.g., logic gates and circuit systems) within the modem subsystem 1012. The CDRX and / or SPS module 1008 may communicate with one or more components of the UE 1000 to implement various aspects of the present disclosure, such as, Figures 4 to 9 , Fig.12 and Fig.14 all aspects.

[0100] In some aspects, the CDRX and / or SPS module 1008 may be configured with other components of the UE 1000 to receive an adjustment indication indicating at least one of a start time of a connected discontinuous reception (CDRX) on-duration, a length of a CDRX on-duration, a start time of a semi-persistent scheduling (SPS) opportunity, and / or a length of an SPS opportunity.

The RF unit 1014 may be configured to process (e.g., perform analog-to-digital conversion or digital-to-analog conversion, etc.) the modulated / encoded data (e.g., communication signals, data signals, control signals, acknowledgments (ACKs), etc.) from the modem subsystem 1012 (regarding outbound transmission). The RF unit 1014 may be further configured to perform analog beamforming in conjunction with digital beamforming. Although shown as being integrated together in the transceiver 1010, the modem subsystem 1012 and the RF unit 1014 may be separate devices that are coupled together at the UE 1000 to enable the UE 1000 to communicate with other devices.

[0102] The RF unit 1014 may provide modulated and / or processed data (e.g., data packets (or more generally, data messages that may include one or more data packets and other information)) to the antenna 1016 for transmission to one or more other devices. The antenna 1016 may also receive data messages sent from other devices. The antenna 1016 may provide the received data messages for processing and / or demodulation at the transceiver 1010. The transceiver 1010 may provide the demodulated and decoded data (e.g., communication signals, data signals, control signals, wake-up signals, adjustment indications, CDRX communications, SPS communications, etc.) to the CDRX and / or SPS module 1008 for processing. The antenna 1016 may include multiple antennas of similar design or different designs to maintain multiple transmit links.

[0103] Fig.11 1 is a block diagram of a network unit 1100 according to one or more aspects of the present disclosure. The network unit 1100 may be as follows: Figures 1 to 9 BS105, DU 240 and / or CU 230 discussed. Therefore, network unit 1100 may include BS. BS may be a converged BS or a decomposed BS as described above. As shown, network unit 1100 may include processor 1102, memory 1104, CDRX and / or SPS module 1108, transceiver 1110 including modem subsystem 1112 and radio frequency (RF) unit 1114, and one or more antennas 1116.

Program code may be used to cause the wireless communication device to perform these operations, for example, by causing one or more processors (such as processor 1102) to control or command the wireless communication device to do so. The terms "instructions" and "code" should be broadly interpreted to include any type of computer-readable statements. For example, the terms "instructions" and "code" may refer to one or more programs, routines, subroutines, functions, procedures, etc. "Instructions" and "code" may include a single computer-readable statement or multiple computer-readable statements.

[0106] The CDRX and / or SPS module 1108 may be implemented via hardware, software, or a combination thereof. For example, the CDRX and / or SPS module 1108 may be implemented as a processor, circuit, and / or instructions 1106 stored in the memory 1104 and executed by the processor 1102. In some instances, the CDRX and / or SPS module 1108 may be integrated within the modem subsystem 1112.

[0108] As shown, the transceiver 1110 may include a modem subsystem 1112 and an RF unit 1114. The transceiver 1110 may be configured to communicate bidirectionally with other devices (such as UE 115, UE 1000, and / or another network element). The modem subsystem 1112 may be configured to modulate and / or encode data according to a modulation and coding scheme (MCS) (e.g., a low-density parity check (LDPC) decoding scheme, a turbo decoding scheme, a convolutional decoding scheme, a digital beamforming scheme, etc.).

The RF unit 1114 may be further configured to perform analog beamforming in conjunction with digital beamforming. Although shown as being integrated together in the transceiver 1110, the modem subsystem 1112 and / or the RF unit 1114 may be separate devices that are coupled together at the network unit 1100 to enable the network unit 1100 to communicate with other devices.

[0109] The RF unit 1114 may provide modulated and / or processed data (e.g., data packets (or more generally, data messages that may include one or more data packets and other information)) to the antenna 1116 for transmission to one or more other devices. The antenna 1116 may also receive data messages sent from other devices and provide the received data messages for processing and / or demodulation at the transceiver 1110.

[0110] Fig.12 1000 is a flowchart illustrating a wireless communication method 1200 according to one or more aspects of the present disclosure. Aspects of the method 1200 may be performed by a computing device (e.g., a processor, a processing circuit, and / or other suitable components) of a wireless communication device or other suitable means for performing blocks. For example, the wireless communication device may be a UE (e.g., UE 115 or UE 1000). The UE may utilize one or more components (such as a processor 1002, a memory 1004, a CDRX and / or SPS module 1008, a transceiver 1010, a modem 1012, an RF unit 1014, and / or one or more antennas 1016) to perform blocks of the method 1200. The method 1200 may be implemented in accordance with Figures 4 to 9 As illustrated, method 1200 includes several enumerated blocks, but aspects of method 1200 may include additional blocks before, after, and between these enumerated blocks. In some aspects, one or more of the enumerated blocks may be omitted or performed in a different order.

[0111] At block 1210, a UE (e.g., UE 115 and / or UE 1000) receives an adjustment indication indicating at least one of a start time of a connected discontinuous reception (CDRX) on-duration, a length of the CDRX on-duration, a start time of a semi-persistent scheduling (SPS) opportunity, and / or a length of an SPS opportunity. The adjustment indication may be UE-specific or for a group of UEs including the UE.

[0112] The UE may receive an adjustment indication from a network element (e.g., network element 1100, BS 105, CU 210, DU 230, and / or RU 240). The UE may receive an adjustment indication from a network element via a physical downlink control channel (PDCCH) communication and / or a physical downlink shared channel (PDSCH) communication. For example, in some instances, the UE may receive an adjustment indication from a network element via a PDCCH, via downlink control information (DCI). The DCI may be a group common DCI or a UE-specific DCI. In some aspects, the adjustment indication may have a format that is the same and / or similar to a wake-up signal (WUS). In some instances, the WUS includes an adjustment indication. In some instances, the UE may receive an adjustment indication from a network element via a PDSCH, via a medium access control control element (MAC-CE). In some aspects, the PDSCH communication may include a MAC-CE that includes an adjustment indication. In some instances, the adjustment indication carried by the MAC-CE indicates at least one of a timing offset for the start of a CDRX on duration and / or a length of a CDRX on duration. In some examples, PDSCH communications may be associated with SPS opportunities associated with a CDRX cycle (e.g., Figure 8 In this regard, in some aspects, the PDSCH communication of the SPS opportunity may include a MAC-CE carrying an adjustment indication, wherein the adjustment indication includes an indication of a start time of a CDRX on duration for a CDRX cycle associated with the SPS.

[0113] In some examples, the UE monitors the Figure 5 , Figure 6 , Figure 7 and Fig. 9 The UE may receive the adjustment indication by monitoring a physical downlink control channel (PDCCH) for the adjustment indication during a period (as shown in FIG. 1 ). The UE may receive a configuration indicating the location (e.g., time resources and / or frequency resources) of one or more monitoring opportunities from a network element. In some examples, the UE may receive the adjustment indication by monitoring a physical downlink control channel (PDCCH) for the adjustment indication during a period (as shown in FIG. 1 ). Figure 8 During the period shown in FIG. 1 , the physical downlink shared channel (PDSCH) is monitored for the adjustment indication to receive the adjustment indication.

[0114] The adjustment indication may indicate the start time of the CDRX On Duration, the length of the CDRX On Duration, the start time of the SPS opportunity, and / or the length of the SPS opportunity in any suitable manner. In some aspects, the adjustment indication indicates the start time of the CDRX On Duration as a timing offset associated with the start time of the CDRX On Duration. The timing offset may be indicated in symbols, subslots, time slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the timing offset may be relative to a nominal start time of the CDRX On Duration (e.g., Figure 7 , as indicated by timing offset 710 in FIG. 1 ), adjusting the reception time of the indication (e.g., as indicated by timing offset 710 in FIG. 1 ). Figure 7 ) and / or the time of sending an acknowledgment (ACK) associated with the adjustment indication (e.g., as indicated by the timing offset 715 in FIG. Figure 7 , as indicated by timing offset 720).

[0115] In some aspects, the adjustment indication indicates the length of the CDRX On Duration. The length of the CDRX On Duration may be indicated in symbols, subslots, time slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the length of the CDRX On Duration may be indicated based on an actual length and / or a relative length. For example, in some instances, the length of the CDRX On Duration may be indicated relative to a nominal length of the CDRX On Duration.

[0116] In some aspects, the adjustment indication indicates the start time of the SPS opportunity as a timing offset associated with the start time of the SPS opportunity. The timing offset may be indicated in symbols, subslots, slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the timing offset may be relative to the nominal start time of the SPS opportunity, the time of receipt of the adjustment indication, and / or the time of transmission of an acknowledgment (ACK) associated with the adjustment indication.

[0117] In some aspects, the adjustment indication indicates the length of the SPS opportunity. The length of the SPS opportunity can be indicated in symbols, subslots, time slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the length of the SPS opportunity can be indicated based on an actual length and / or a relative length. For example, in some instances, the length of the SPS opportunity can be indicated relative to the nominal length of the SPS opportunity.

[0118] At block 1220, the UE sends an acknowledgment (ACK) associated with the adjustment indication (e.g., Figures 5 to 8). The UE may send an ACK to the network element from which the UE received the adjustment indication. In some instances, the UE sends the ACK using PUCCH format 0 or PUCCH format 1. In some instances, the UE sends the ACK based on when the UE receives the adjustment indication and / or when the network element sends the adjustment indication (e.g., based on a HARQ process associated with a resource in which the adjustment indication was received). In some instances, the UE sends the ACK within a time period that is offset from a last monitoring opportunity interval timing of the one or more monitoring opportunities (e.g., as shown in FIG. 1 ). Figure 7 That is, the UE may monitor for adjustment indications in one or more monitoring occasions, and if the UE receives an adjustment indication in any of the monitoring occasions, the UE sends an ACK using the same resources as the last monitoring occasion interval, regardless of which monitoring occasion the adjustment indication was received. In order to save power, save processing and / or efficiently utilize network resources, the UE may avoid sending a negative acknowledgement (NACK) when the UE fails to receive an adjustment indication during any of the monitoring occasions. As shown in Fig. 9 and Fig.14 As further discussed in the context of , in some instances, when the UE does not receive an adjustment indication and / or WUS for the CDRX on-duration, the UE may adjust the CDRX on-duration based on the data stream associated with the CDRX on-duration (e.g., Figure 4 The start time of the CDRX on-duration may be adjusted by jitter of XR stream 1 405a and / or XR stream 2 405b).

[0119] At block 1230, the UE monitors communications based on a start time of the CDRX on duration, a length of the CDRX on duration, a start time of the SPS opportunity, and / or a length of the SPS opportunity as indicated by the adjustment indication. For example, when the adjustment indication includes an indication of a start time of the CDRX on duration, the UE may begin monitoring communications based on the start time of the CDRX on duration as indicated by the adjustment indication, which start time may be offset from a nominal start time of the CDRX on duration. Similarly, when the adjustment indication includes an indication of a length of the CDRX on duration, the UE may monitor communications based on the length of the CDRX on duration as indicated by the adjustment indication, which length may be different from the nominal length of the CDRX on duration. Further, when the adjustment indication includes an indication of both a start time and a length of the CDRX on duration, the UE may begin monitoring communications based on the start time of the CDRX on duration as indicated by the adjustment indication, and monitor communications based on the length of the CDRX on duration as indicated by the adjustment indication. When the adjustment indication includes an indication of the length of the CDRX OnDuration but does not indicate a start time of the CDRX OnDuration, the UE may begin monitoring for communications at the nominal start time of the CDRX OnDuration.

[0120] When the adjustment indication includes an indication of a start time of an SPS opportunity, the UE may begin monitoring communications based on the start time of the SPS opportunity as indicated by the adjustment indication, which start time may be offset from the nominal start time of the SPS opportunity. Similarly, when the adjustment indication includes an indication of a length of the SPS opportunity, the UE may monitor communications based on the length of the SPS opportunity as indicated by the adjustment indication, which length may be different from the nominal length of the SPS opportunity. Further, when the adjustment indication includes an indication of both the start time and the length of the SPS opportunity, the UE may begin monitoring communications based on the start time of the SPS opportunity as indicated by the adjustment indication, and monitor communications based on the length of the SPS opportunity as indicated by the adjustment indication. When the adjustment indication includes an indication of the length of the SPS opportunity but does not indicate a start time of the SPS opportunity, the UE may begin monitoring communications at the nominal start time of the SPS opportunity.

[0121] In some aspects, the UE receives communications based on the monitoring at block 1230. The communications may include one or more PDSCH communications, PDCCH communications, and / or other communications. In some instances, the communications include communications with a data stream (e.g., Figure 4 XR stream 1 405a and / or XR stream 2 405b) associated with a data burst (e.g., Figure 4 XR data bursts 420a, 420b, 440a, 440b).

[0122] Fig.131300 according to one or more aspects of the present disclosure. Aspects of the method 1300 may be performed by a computing device (e.g., a processor, a processing circuit, and / or other suitable components) of a wireless communication device or other suitable means for executing blocks. For example, the wireless communication device may include a network unit (e.g., a network unit 1100, a BS 105, a CU 210, a DU 230, and / or a RU 240). The network unit 1100 may utilize one or more components (such as a processor 1102, a memory 1104, a CDRX and / or SPS module 1108, a transceiver 1110, a modem 1112, an RF unit 1114, and / or one or more antennas 1116) to execute the blocks of the method 1300. The method 1300 may be implemented in accordance with Figures 4 to 9 As illustrated, method 1300 includes several enumerated blocks, but aspects of method 1300 may include additional blocks before, after, and between these enumerated blocks. In some aspects, one or more of the enumerated blocks may be omitted or performed in a different order.

[0123] At block 1310, a network unit (network unit 1100, BS 105, CU 210, DU 230, and / or RU 240) sends an adjustment indication indicating at least one of a start time of a connected discontinuous reception (CDRX) on duration, a length of a CDRX on duration, a start time of a semi-persistent scheduling (SPS) opportunity, and / or a length of an SPS opportunity. The network unit may send the adjustment indication to a UE (e.g., UE 115 and / or UE 1000). The adjustment indication may be UE-specific or for a group of UEs including the UE. The network unit may send the adjustment indication to the UE via a physical downlink control channel (PDCCH) communication and / or a physical downlink shared channel (PDSCH) communication. For example, in some instances, the network unit may send the adjustment indication to the UE via PDCCH, via downlink control information (DCI). The DCI may be a group common DCI or a UE-specific DCI. In some aspects, the adjustment indication may have a format identical and / or similar to a wake-up signal (WUS). In some instances, the WUS includes the adjustment indication. In some instances, the network element may send the adjustment indication to the UE via the PDSCH, via a medium access control control element (MAC-CE). In some aspects, the PDSCH communication may include a MAC-CE that includes the adjustment indication. In some instances, the adjustment indication carried by the MAC-CE indicates at least one of a timing offset for the start of the CDRX on duration and / or a length of the CDRX on duration. In some instances, the PDSCH communication may be associated with an SPS opportunity associated with a CDRX cycle (e.g., such as Figure 8In this regard, in some aspects, the PDSCH communication of the SPS opportunity may include a MAC-CE carrying an adjustment indication, wherein the adjustment indication includes an indication of a start time of a CDRX on duration for a CDRX cycle associated with the SPS.

[0124] In some examples, the network element may monitor the UE at one or more monitoring occasions (e.g., Figure 5 , Figure 6 , Figure 7 and Fig. 9 The network element may schedule the sending of the adjustment indication to align with the monitoring opportunities of the UE. Further, the network element may send a configuration indicating the location (e.g., time resources and / or frequency resources) of one or more monitoring opportunities to the UE. In some examples, the network element sends the adjustment indication during one or more scheduled downlink communication opportunities (which may include SPS opportunities (e.g., such as Figure 8 As shown)), the adjustment indication is sent via the physical downlink shared channel (PDSCH) during the period.

[0125] The adjustment indication sent by the network element indicates the start time of the CDRX On Duration, the length of the CDRX On Duration, the start time of the SPS opportunity, and / or the length of the SPS opportunity in any suitable manner. In some aspects, the adjustment indication indicates the start time of the CDRX On Duration as a timing offset associated with the start time of the CDRX On Duration. The timing offset may be indicated in symbols, sub-slots, time slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the timing offset may be relative to a nominal start time of the CDRX On Duration (e.g., Figure 7 , as indicated by timing offset 710 in FIG. 1 ), adjusting the reception time of the indication (e.g., as indicated by timing offset 710 in FIG. 1 ). Figure 7 ) and / or the time of sending an acknowledgment (ACK) associated with the adjustment indication (e.g., as indicated by the timing offset 715 in FIG. Figure 7 , as indicated by timing offset 720).

[0126] In some examples, the network unit determines the start time of the CDRX on duration, the length of the CDRX on duration, the start time of the SPS opportunity, and / or the length of the SPS opportunity. The network unit may determine the start time of the CDRX on duration, the length of the CDRX on duration, the start time of the SPS opportunity, and / or the length of the SPS opportunity based on the data stream (e.g., Figure 4 The start time of the CDRX on duration, the length of the CDRX on duration, the start time of the SPS opportunity and / or the length of the SPS opportunity may be determined based on jitter associated with XR stream 1 405a and / or XR stream 2 405b) and / or one or more other communication parameters and / or network traffic parameters.

[0127] In some aspects, the adjustment indication sent by the network element indicates the length of the CDRX On Duration. The length of the CDRX On Duration may be indicated in symbols, sub-slots, time slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the length of the CDRX On Duration may be indicated based on an actual length and / or a relative length. For example, in some instances, the length of the CDRX On Duration may be indicated relative to a nominal length of the CDRX On Duration.

[0128] In some aspects, the adjustment indication sent by the network element indicates the start time of the SPS opportunity as a timing offset associated with the start time of the SPS opportunity. The timing offset may be indicated in symbols, subslots, slots, milliseconds, microseconds, or other suitable units of measurement. In this regard, the timing offset may be relative to the nominal start time of the SPS opportunity, the time of receipt of the adjustment indication, and / or the time of transmission of an acknowledgment (ACK) associated with the adjustment indication.

[0129] In some aspects, the adjustment indication sent by the network element indicates the length of the SPS opportunity. The length of the SPS opportunity can be indicated by symbols, subslots, time slots, milliseconds, microseconds or other suitable units of measurement. In this regard, the length of the SPS opportunity can be indicated according to an actual length and / or a relative length. For example, in some instances, the length of the SPS opportunity can be indicated relative to the nominal length of the SPS opportunity.

[0130] At block 1320, the network element receives an acknowledgment (ACK) associated with the adjustment indication (e.g., Figures 5 to 8 ). The network element may receive an ACK from the UE that received the adjustment indication. In this regard, the adjustment indication may be specific to the UE or to a group of UEs that include the UE. In some instances, the network element receives the ACK based on when the network element sent the adjustment indication and / or when the UE received the adjustment indication (e.g., based on a HARQ process associated with a resource in which the adjustment indication was received). In some instances, the network element receives the ACK within a time period that is a timing offset from a last monitoring opportunity interval of one or more monitoring opportunities of the UE (e.g., as Figure 7 That is, the network element may use the same resources as the last monitoring opportunity interval to receive the ACK, regardless of which monitoring opportunity the network element sent the adjustment indication in. In some instances, when the UE fails to receive the adjustment indication during any of the monitoring opportunities, the network element expects to receive only an ACK from the UE and does not expect to receive a negative acknowledgement (NACK) from the UE.

[0131] At block 1330, the network element sends a communication based on the start time of the CDRX on duration, the length of the CDRX on duration, the start time of the SPS opportunity, and / or the length of the SPS opportunity indicated by the adjustment indication. The communication may include one or more PDSCH communications, PDCCH communications, and / or other communications. In some examples, the communication includes communication with a data stream (e.g., Figure 4 XR stream 1 405a and / or XR stream 2 405b) associated with a data burst (e.g., Figure 4 XR data bursts 420a, 420b, 440a, 440b).

[0132] When the adjustment indication includes an indication of a start time of the CDRX On Duration, the network element may send communications within a time period based on the start time of the CDRX On Duration as indicated by the adjustment indication, which start time may be offset from the nominal start time of the CDRX On Duration. Similarly, when the adjustment indication includes an indication of a length of the CDRX On Duration, the network element may send communications within a time period based on the length of the CDRX On Duration as indicated by the adjustment indication, which length may be different from the nominal length of the CDRX On Duration. Further, when the adjustment indication includes an indication of both the start time and the length of the CDRX On Duration, the network element sends communications within a time period based on the start time and the length of the CDRX On Duration as indicated by the adjustment indication.

[0133] When the adjustment indication includes an indication of a start time of the SPS opportunity, the network element may send communications during a time period based on the start time of the SPS opportunity as indicated by the adjustment indication, which start time may be offset from the nominal start time of the SPS opportunity. Similarly, when the adjustment indication includes an indication of a length of the SPS opportunity, the network element may send communications during a time period based on the length of the SPS opportunity as indicated by the adjustment indication, which length may be different from the nominal length of the SPS opportunity. Further, when the adjustment indication includes an indication of both the start time and the length of the SPS opportunity, the network element may send communications during a time period based on the start time of the SPS opportunity as indicated by the adjustment indication, and monitor communications based on the length of the SPS opportunity as indicated by the adjustment indication.

[0134] In some aspects, the UE successfully receives and decodes the communication sent by the network element block 1230. In some aspects, the network element may receive an ACK for the communication. In some instances, the UE fails to receive and / or fails to successfully decode the communication sent by the network element block 1230, in which case the network element may receive a negative acknowledgement (NACK) from the UE or not receive an ACK from the UE.

[0135] Fig.141400 according to one or more aspects of the present disclosure. Aspects of method 1400 may be performed by a computing device (e.g., a processor, a processing circuit, and / or other suitable components) of a wireless communication device or other suitable means for performing blocks. For example, the wireless communication device may be a UE (e.g., UE 115 or UE 1000). The UE may utilize one or more components (such as a processor 1002, a memory 1004, a CDRX and / or SPS module 1008, a transceiver 1010, a modem 1012, an RF unit 1014, and / or one or more antennas 1016) to perform blocks of method 1200. Method 1400 may be performed in accordance with Figures 4 to 9 As illustrated, method 1400 includes several enumerated blocks, but aspects of method 1400 may include additional blocks before, after, and between these enumerated blocks. In some aspects, one or more of the enumerated blocks may be omitted or performed in a different order.

[0136] At block 1410, a UE (e.g., UE 115 or UE 1000) receives a signal from a connected discontinuous reception (CDRX) on-duration during one or more monitoring occasions (e.g., Figure 5 , Figure 7 , Figure 8 and Fig. 9 100, BS105, CU 210, DU 230, and / or RU 240). The UE may receive a configuration or other communication indicating the location (e.g., time resources and / or frequency resources) of one or more monitoring opportunities from a network unit (e.g., network unit 1100, BS105, CU 210, DU 230, and / or RU 240). The UE may receive an indication of the location of one or more monitoring opportunities via RRC communication, PDCCH communication, PDSCH communication, and / or other suitable communication. In some examples, one or more monitoring opportunities are indicated in a CDRX configuration associated with a CDRX on duration. The UE may receive a configuration or other communication indicating the nominal start time of the CDRX on duration and / or the start time of multiple CDRX on durations of a CDRX cycle from a network unit. The UE may receive an indication of the start time of the CDRX on duration via RRC communication, PDCCH communication, PDSCH communication, and / or other suitable communication. In some examples, the start time of the CDRX On Duration is indicated in a CDRX configuration associated with the CDRX On Duration.

[0137] At block 1420, based on the failure to receive a WUS during one or more monitoring opportunities at block 1410, the UE monitors communications associated with the data stream during the CDRX on duration. The UE may monitor communications using the start time of the CDRX on duration based on the nominal start time of the CDRX on duration and the jitter (e.g., maximum jitter, median jitter, average jitter, etc.) of the data stream. That is, the UE may determine a start time of the CDRX on duration that adjusts the nominal start time of the CDRX on duration based on the maximum jitter of the data stream. For example, the UE may determine the start time of the CDRX on duration by adding or subtracting a time relative to the nominal start time of the CDRX on duration based on the maximum jitter. Thus, the determined start time may be the same as the nominal start time (e.g., when the data stream has no jitter or has minimal jitter) or offset from the nominal start time (e.g., when the data stream has jitter). The UE may monitor communications starting from the determined start time of the CDRX on duration.

[0138] In some aspects, the UE receives an indication of jitter (e.g., maximum jitter, median jitter, average jitter, etc.) of a data stream. The UE may receive an indication of jitter from a network element. In some instances, the indication of jitter may be an explicit indication or an implicit indication. For example, the UE may receive an explicit indication of jitter (e.g., maximum jitter measurement, median jitter measurement, average jitter measurement, etc.) from a network element. The network element may provide an explicit indication of jitter to the UE to allow the UE to adjust the start time of one or more CDRX on durations and / or adjust for other communication purposes. In some aspects, the UE may determine a jitter parameter using information about jitter received by one or more higher layers of the UE, the jitter parameter being used to adjust the start time of the CDRX on duration. In some instances, the indication of jitter may be an implicit indication. For example, the UE may receive an indication of one or more higher layer parameters associated with a communication stream from a network element, the indication being used by the UE to determine a jitter parameter, the jitter parameter being used to adjust the start time of the CDRX on duration. The UE may receive an explicit and / or implicit indication of jitter via RRC communication, PDCCH communication, PDSCH communication, and / or other suitable communication.
