Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) can support various extended reality (XR) applications. In some examples of XR applications, features from a real environment and a virtual environment can be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misregistration of objects from the real environment and the virtual environment, and other visual conflicts, the UE can generate and send pose information to a network (e.g., a server hosting the XR application). The UE can be configured to manage the sending of the pose information to the network, which can result in reduced power consumption. For example, the UE can determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and send the pose information only during the downlink burst occasion.

Technical Field

[0003] The following relates to wireless communication, and more specifically to techniques for managing uplink wireless communication to save power. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems are capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-APro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can 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 Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). Components within a wireless communication system can be coupled to each other (e.g., operational ground, communication ground, functional ground, electronic ground, and / or electrical ground).

[0005] A wireless multiple-access communication system can include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which can be otherwise known as user equipments (UEs). These communication devices can support various extended reality (XR) applications, such as augmented reality (AR), mixed reality (MR), and virtual reality (VR). In XR applications, these communication devices can generate and transmit pose information to avoid visual conflicts, such as object misregistration between real and virtual environments and other visual conflicts. In some cases, the transmission of pose information and other control information by these communication devices can occur too frequently and result in unnecessary additional power consumption. Accordingly, it can be desirable to control the transmission of pose information and other control information to conserve power, among other beneficial effects. SUMMARY

[0006] Various aspects of the present disclosure relate to configuring communication devices, such as UEs and base stations, e.g., eNodeBs (eNBs), next generation NodeBs or giga-NodeBs (either of which can be referred to as a gNB), of a wireless communication system to support managing uplink wireless communications to conserve power. For example, a UE can be configured to generate and transmit pose information when a downlink burst from a base station is occurring, e.g., a downlink frame transmission associated with an XR application. This allows for alignment between uplink transmissions, e.g., pose information transmissions, and downlink receptions, e.g., frame receptions, which can reduce unnecessary UE wake-up periods and provide the UE with an opportunity to enter an extended sleep (low power) state. To support alignment between uplink transmissions and downlink receptions, the UE can be configured to synchronize an uplink transmission rate with a downlink burst rate. The UE can also be configured to determine one or more slots relative to a downlink slot of a downlink burst for transmitting pose information. By managing the transmission of pose information or other control information related to an XR application, the UE can reduce power consumption. Accordingly, the present disclosure can also include improvements to pose or other control information operations, and in some examples, can facilitate high reliability and low latency XR-related operations, among other beneficial effects.

[0045] Some wireless communications systems can include communication devices, such as UEs and base stations, e.g., eNBs, gNBs, that can support multiple radio access technologies. Examples of radio access technologies include 4G systems, such as LTE systems, and 5G systems, which can be referred to as NR systems. UEs can support various types of applications, such as XR applications, such as AR, MR, and VR, which can have periodic or semi-periodic data traffic. Applications can be hosted by a server as described herein. The server can send periodic or semi-periodic data traffic to a base station, which can forward the data traffic to a UE. The base station can forward the data traffic to the UE using multiple transport blocks (also referred to as transport block bursts).

[0046] For XR applications, features from real and virtual environments can be overlaid and displayed to a user for consumption via a UE. To avoid visual conflicts, such as misaligning objects with real and virtual environments, and other visual conflicts, the UE can sense, generate, and send pose information to a network (e.g., a server hosting an XR application). The pose information can define a location and orientation of the UE (or user) in space relative to real and virtual environments. In some cases, the sending of pose information by the UE can occur continuously and result in wasted power consumption. For example, the UE continuously sends pose information to the network without any mechanism to reduce or control the sending of pose information to reduce power (e.g., enter a lower power mode).

[0047] Various aspects of the described technology relate to configuring a UE to provide power saving improvements that manage pose information sending, as well as other control information sending. For example, a UE can be configured to generate and send pose information when a downlink burst (e.g., a downlink frame transmission associated with an XR application) from a network is occurring. This allows for alignment between uplink sending (e.g., pose information sending) and downlink reception (e.g., frame reception), which can reduce unnecessary wake-up periods and provide the UE with an opportunity to enter an extended sleep state. To support alignment between uplink sending and downlink reception, the UE can be configured to synchronize an uplink sending rate with a downlink burst rate. The UE can also be configured to determine one or more slots relative to downlink slots of a downlink burst for sending pose information.

[0048] Aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential improvements, as well as other improvements. Techniques employed by a UE can provide benefits and enhancements for operation of the UE. For example, operations performed by a UE can provide power saving improvements for the UE. In some examples, configuring a UE to reduce or control posture information transmissions during downlink burst occasions can reduce power consumption of the UE. In some other examples, configuring a UE to reduce or control posture information transmissions during downlink burst occasions can facilitate higher reliability and lower latency XR-related operations, among other benefits.

[0049] Aspects of the disclosure are first described in the context of a wireless communications system. Aspects of the disclosure are further illustrated and described in connection with diagrams, system diagrams, and flowcharts related to techniques for managing uplink transmissions for power savings.

[0050] Figure 1 An example of a wireless communications system 100 that supports techniques for managing uplink transmissions for power savings is shown in accordance with aspects of the present disclosure. The wireless communications system 100 can include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 can be a LTE network, a LTE-A network, a LTE-A Pro network, or a NR network. In some examples, the wireless communications system 100 can support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0051] The base stations 105 can be dispersed throughout the geographic area to form the wireless communications system 100 and can be of different forms or have different capabilities. The base stations 105 and UEs 115 can wirelessly communicate via one or more communication links 125. Each base station 105 can provide a coverage area 110 over which UEs 115 and base stations 105 can establish one or more communication links 125. The coverage area 110 can be an example of a geographic area over which the base station 105 and a UE 115 can support the communication of signals according to one or more radio access technologies.

[0052] The UEs 115 can be dispersed throughout the coverage areas 110 of the wireless communications system 100, and each UE 115 can be stationary, or mobile, or both. UEs 115 can be devices of different forms or capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in FIG. 1.Figure 1 as shown.

[0053] The base stations 105 can communicate with the core network 130, or with one another, or both. For example, the base stations 105 can interface with the core network 130 through one or more backhaul links 120 (e.g., via an SI, N2, N3, or other interface). The base stations 105 can communicate with one another over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., direct

[0054] The UEs 115 can include or can be referred to as mobile devices, wireless devices, remote devices, handheld devices, or subscriber devices, or some other suitable terminology, where the “device” can also be referred to as a unit, a station, a terminal, or a client, among other examples. The UEs 115 can also include or can be referred to as personal electronic devices such as cellular phones, personal digital assistants (PDAs), multimedia / entertainment devices (e.g., radios, MP3 players or video devices), cameras, gaming devices, navigation / location devices (e.g., GNSS (global navigation satellite system) devices based on, for example, GPS (global positioning system), Beidou, GLONASS, or Galileo, or terrestrial-based devices), tablets, laptops, netbooks, smartbooks, personal computers, smart devices, wearable devices (e.g., smart watches, smart clothing, smart glasses, virtual reality eyewear, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), drones, robots / robotic devices, vehicles, vehicle devices, meters (e.g., parking meters, electricity meters, gas meters, water meters), monitors, gas pumps, appliances (e.g., kitchen appliances, washing machines, dryers), location tags, medical / healthcare devices, implants, sensors / actuators, displays, or any other suitable device that is configured to communicate via a wireless or wired medium. In some examples, a UE 115 can include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which can be implemented in various objects such as appliances or vehicles, meters, etc. The UEs 115 described herein can be able to communicate with various types of base stations and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as described herein. The UEs 115 can be implemented or referred to as other terminology, such as a mobile station, a subscriber station, a subscriber unit, a mobile subscriber, a station, a customer premises equipment (CPE), or some other suitable terminology.Figure 1 are shown.

[0055] The UEs 115 and the base stations 105 can wirelessly communicate with one another via one or more communication links 125 over one or more carriers. The term “carrier” can refer to a set of radio frequency spectrum resources (e.g., frequency channels) with a defined physical layer structure configured for supporting

[0056] In some examples (e.g., in carrier aggregation configurations), a carrier can also have acquisition signaling or control signaling that coordinates operations of other carriers. A carrier can be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and can be positioned based on a channel raster so as to be discovered by a UE 115. Carriers can be operated in an independent mode in which initial acquisition and connection can be performed by a UE 115 independently with carriers, or carriers can be operated in a non-independent mode (e.g., same or different radio access technologies) in which different carriers anchor connections.

[0057] The communication links 125 shown in wireless communication system 100 can include uplink transmissions from a UE 115 to a base station 105, or downlink transmissions from a base station 105 to a UE 115. Carriers can carry downlink or uplink communications (e.g., in an FDD mode) or can be configured to carry downlink and uplink communications (e.g., in a TDD mode). A carrier can be associated with a particular bandwidth of the radio frequency spectrum, and in some examples the carrier bandwidth can be referred to as a “system bandwidth” of the carrier or the wireless communication system 100. For example, the carrier bandwidth can be one of a number of determined bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base stations 105 or UEs 115, or both) can have hardware configurations that support communications over a particular carrier bandwidth or can be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communication system 100 can include base stations 105 or UEs 115 that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate over portions (e.g., sub-bands, BWPs) or all of the carrier bandwidth.

[0058] Signal waveforms transmitted over a carrier can be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as OFDM or DFT-S-OFDM). In a system employing MCM techniques, a resource element can consist of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). The more resource elements that a UE 115 receives and the higher the order of the modulation scheme, the higher the data rates for the UE 115. A wireless communications resource can refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate for communications with a UE 115.

[0059] One or more parameter sets can be supported for a carrier, where a parameter set can include a subcarrier spacing (Af) and a cyclic prefix. One carrier can be divided into one or more BWPs with same or different parameter sets. In some examples, a UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time and communications for a UE 115 can be restricted to one or more active BWPs. Time intervals for a base station 105 or UE 115 can be expressed in multiples of a basic time unit (e.g., which can be a sampling period of 1 millisecond (ms) or a sampling period Ts= 1 / (Δfmax·Nf) ms, where Δfmax can be a maximum supported subcarrier spacing, and Nf can be a maximum supported discrete Fourier transform (DFT) size).s = 1 / (Af max • N f ) seconds, where Af max may represent a maximum supported subcarrier spacing, and N f may represent a maximum supported discrete Fourier transform (DFT) size. Time intervals can be expressed in multiples of a basic time unit (e.g., a sampling period of Ts= 1 / (Af

[0060] Each frame can include a plurality of sequentially numbered subframes or slots, and each subframe or slot can have the same duration. In some examples, a frame can be divided (e.g., in the time domain) into subframes, and each subframe can be further divided into multiple slots. Alternatively, each frame can include a variable number of slots, and the number of slots can depend on the subcarrier spacing. Each slot can include a plurality of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communications systems 100, a slot can be further divided into multiple mini-slots containing one or more symbols. In addition to the cyclic prefix, each symbol period can contain one or more (e.g., N f ) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating band. A subframe, a slot, a mini-slot, or a symbol can be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and can be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) can be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0061] Physical channels can be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel can be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel can be defined by a number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search control regions for control information according to one or more search space sets, and each search space set can include one or more control channel candidates arranged in an epilogical manner in one or more aggregation levels. An aggregation level for a control channel candidate can refer to a number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets can include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets configured for sending control information to a specific UE 115.

[0062] Each base station 105 can provide communication coverage for one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells or any combination thereof). The term “cell” can refer to a logical communication entity used for communication with a base station 105 (e.g., through a carrier) and can be associated with a identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifiers) used by a base station 105 to identify the cell. In some examples, a cell can also refer to a geographical area 110 or a subset of a geographical area 110 (e.g., a sector) over which a logical communication entity operates. The size of such a cell can vary depending on a variety of factors such as capacity requirements, spectral efficiency, and / or other factors. For example, a cell can be or include a building, a subset of a building, or an outdoor space between or overlapping with geographical coverage areas 110, among other examples.

[0063] Macro cells can cover relatively large geographic areas (e.g., 100s of meters to 10s of kilometers in radius) and can allow for a large number of UEs 115 to access the macro cell, with access to a network provider's services. Small cells can include one or more base stations 105 that provide service to a relatively small geographic area (e.g., a home, a business, a vehicle, a campus, a row of city blocks, or other small geographic areas). Small cells can provide service to a UE 115 in a restricted access area, or service to a UE 115 that has a subscription with a network provider that is associated with the small cell. Small cells can be deployed within a macro cell, and can provide better service to a UE 115 in a restricted access area, or can provide better overall service to UEs 115 in the small cell's geographic area of service.

[0064] In some examples, base stations 105 can be movable and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, the overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communications system 100 can include, for example, a heterogeneous network in which different types of the base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0065] The wireless communications system 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operation, the base stations 105 can have different frame timings, and transmissions from different base stations 105 can not be aligned in time. The techniques described herein can be used for either synchronous or asynchronous operation.

[0066] Some UEs 115, such as MTC or IoT devices, can be low cost or low complexity devices, and can provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with one another or a base station 105 without the need for human intervention. In some examples, M2M communication or MTC can include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program, which can make use of the information or present it to humans in the form of an alert or notification. Some UEs 115 can be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging. In one aspect, the technologies disclosed herein can be applicable to MTC or IoT UEs. MTC or IoT UEs can include MTC / enhanced MTC (eMTC, also referred to as CAT-M, CAT Ml) UEs, NB-IoT (also referred to as CAT NB1) UEs, and other types of UEs. eMTC and NB-IoT can refer to future technologies that can evolve from or be based on these technologies. For example, eMTC can include FeMTC (further eMTC), eFeMTC (enhanced further eMTC), or mMTC (massive MTC), among other examples, while NB-IoT can include eNB-IoT (enhanced NB-IoT), or FeNB-IoT (further enhanced NB-IoT).

[0067] Some UEs 115 can be configured to employ operating modes that reduce power consumption, such as a half-duplex communication (e.g., a mode in which a device supports

[0068] The wireless communications system 100 can be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 can be configured to support ultra-reliable low-latency communications (URLLC) or mission critical communications. UEs 115 can be designed to support ultra-reliable, low-latency, or mission critical (e.g., mission critical function) functions. Ultra-reliable communications can include private communication or group communication, and can be supported by one or more mission critical services such as mission critical push-to-talk (MCPTT), mission critical video (MCVideo), or mission critical data (MCData). Support for mission critical functions can include prioritization of services, and mission critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission critical, and ultra-reliable low-latency can be used interchangeably herein.

[0069] The base stations 105 and UEs 115 can support various types of applications that can have periodic or semi-periodic data traffic. The base stations 105 can be in wireless communication with a server (not shown) that can provide periodic or semi-periodic data traffic to the base stations 105 for forwarding to the UEs 115. The server can be a cloud server, a server associated with an application subscription provider, a proxy server, a web server, an application server, or any combination thereof. The server can include an application distribution platform. The application distribution platform can allow UEs 115 to discover, browse, share, and download applications via the base stations 105, and thus provide digital distribution of applications from the application distribution platform. Thus, digital distribution can be a form of delivering content such as data without the use of physical media but through an online delivery medium such as the Internet. For example, the UEs 115 can upload or download applications for streaming, downloading, uploading, or processing data (e.g., images, audio, video). The server can also send various information to the UEs 115, such as instructions or commands to download applications on the UEs 115 via the base stations 105.

[0070] As an example, the base stations 105 and UEs 115 can support XR applications, which can have periodic or semi-periodic XR data traffic. The XR applications can support various frame rates, such as a 60 MHz frame rate or a 120 MHz frame rate. A server can generate 60 MHz XR frames, which can correspond to a periodicity of 16.67 ms. Alternatively, the server can generate 120 MHz XR frames, which can correspond to a periodicity of 8.33 ms. The server can transmit the periodic or semi-periodic XR data traffic to the base stations 105, which can forward the XR data traffic to the UEs 115. The server can partition the XR data traffic into multiple slices (also referred to as files), and encode each slice separately, and transmit the encoded slices to the base stations 105, which can forward the XR data traffic to the UEs 115 using multiple transport blocks (also referred to as bursts of transport blocks).

[0071] For XR applications, features from real and virtual environments can be overlaid and displayed to a user for consumption via the UE 115. To avoid visual conflicts, such as misaligning objects with real and virtual environments, and other visual conflicts, the UE 115 can generate and transmit pose information to a network (e.g., a server hosting the XR application). The pose information can define a position and orientation of the UE 115 (or user) in space relative to the real and virtual environments. In some cases, different applications can have different uplink data streams.

[0072] For VR applications, there can be a single uplink data stream. For example, the UE 115 can generate pose information (e.g., six degrees of freedom (6DOF) pose information) and other control information. In some examples, the UE 115 can generate or transmit the pose information based at least in part on a data rate (e.g., 0.5-2 Mbps). The UE 115 can transmit the pose information and other control information based on an uplink transmission periodicity (e.g., 2 mn (500 Hz)). In some examples, the pose information and other control information can have different file sizes (e.g., 0.5 Mbits / 500 = 1 Kbits = 125 bytes, 2 Mbits / 500 = 4 Kbits = 500 bytes). A full delivery basis (FDB) can be 1.25 ms to 10 ms.

[0073] For AR applications, there can be two uplink data streams. As part of a first uplink data stream, the UE 115 can generate pose information (e.g., 6DOF pose information) and other control information. The UE 115 can generate or transmit the pose information based at least in part on a data rate (e.g., 0.5-2 Mbps). The UE 115 can transmit the pose information and other control information based on an uplink transmission periodicity (e.g., 2 mn (500 Hz)). Similarly, for AR applications, the FDB can be 1.25 ms to 10 ms. As part of a second uplink data stream, the UE 115 can generate pose information for scene updates associated with the AR application. For scene updates, the UE 115 can generate or transmit the pose information based at least in part on a data rate (e.g., 10 Mbps, 10 Hz). In some examples, the pose information can have a different file size (e.g., 1 Mbit / 100 ms = 125 kbytes). The FDB can be 100 ms.

[0074] The UE 115 can benefit from periodic or semi-periodic data traffic, and more specifically, from the transmission delay between bursts of transport blocks carrying periodic or semi-periodic data traffic to implement various operations to reduce power consumption. However, in some cases, the UE 115 can transmit pose information too frequently and result in unnecessary additional power consumption. Various aspects of the described techniques are directed to configuring the UE 115 to provide power saving improvements that manage pose information transmissions, as well as other control information transmissions. For example, the UE 115, via the UE communications manager 102, can be configured to generate and transmit pose information when a downlink burst (e.g., a downlink frame transmission associated with an XR application) from the base station 105 is occurring. This allows for alignment between uplink transmissions (e.g., pose information transmissions) and downlink receptions (e.g., frame receptions), which can reduce unnecessary wake-up periods and provide the UE with an opportunity to enter an extended sleep state. To support alignment between uplink transmissions and downlink receptions, the UE 115, via the UE communications manager 102, can be configured to synchronize an uplink transmission rate with a downlink burst rate. The UE 115 can also be configured to determine one or more slots relative to downlink slots of the downlink burst for transmitting pose information as described herein. Thus, the UE 115 can include improvements to pose or other control information operations, and in some examples, can facilitate high reliability and low latency XR-related operations, among other beneficial effects.

[0075] In some examples, a UE 115 can also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communications can be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group can be outside the geographic coverage area 110 of a base station 105 or be otherwise unable to receive transmissions from a base station 105. In some examples, groups of UEs 115 communicating via D2D communications can utilize a one-to-many (1 :M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, a base station 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out between UEs 115 without the involvement of a base station 105.

[0076] In some systems, the D2D communication link 135 can be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115). In some examples, vehicles can communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle can signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to V2X systems. In some examples, a vehicle in a V2X system can communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communications, or can communicate both.

[0077] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or 5G core (5GC), which can include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets can be transferred through the user plane entity, which can provide IP address allocation as well as other functions. The user plane entity can be connected to the IP services 150 of the one or more network operators. The IP services 150 can include access to the Internet, Intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0078] Some of the network devices, such as a base station 105, can include subcomponents such as an access network entity 140, which can be an example of an access node controller (ANC). Each access network entity 140 can communicate with UEs 115 through one or more other access network transmission entities 145, which can be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transmission entity 145 can include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 can be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., a base station 105).

[0079] Wireless communications system 100 can operate using one or more frequency bands, in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band, since the wavelengths range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features, but the waves can penetrate structures sufficiently for a macro cell to provide service within an indoor location. Transmission of UHF waves may

[0080] Wireless communications system 100 can also operate in a frequency band from 3 GHz to 30 GHz, also known as the centimeter band, or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as the millimeter band. In some examples, wireless communications system 100 can support millimeter wave (mmW) communications between UEs 115 and base stations 105, and EHF antennas of the respective devices can be even smaller and more closely spaced than UHF antennas. In some examples, this can facilitate using antenna arrays within a device. However, the propagation of EHF transmissions, compared to UHF transmissions, can be subject to even more atmospheric attenuation and shorter range. Techniques disclosed herein can be employed across transmissions that use one or more different frequency regions, and designated use of bands across these frequency regions can differ from country to country or regulatory jurisdiction to regulatory jurisdiction.

[0081] Wireless communications system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communications system 100 can employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed

[0082] Base stations 105 or UEs 115 can be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. Antennas of a base station 105 or a UE 115 can be co-located or located at different geographic locations. For example, one or more base station antennas or antenna arrays can be located at antenna assembly sites associated with the base station 105. In some examples, antennas associated with a base station 105 can be located in different geographic locations. A base station 105 can have an antenna array with a number of rows and columns of antenna ports that the base station 105 can use for supporting beamforming of communications with UEs 115. Similarly, a UE 115 can have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels can support radio frequency beamforming of signals transmitted via antenna ports.

[0083] Base stations 105 or UEs 115 can utilize MIMO communications to exploit multipath signal propagation and increase the spectral efficiency of wireless communications. Such techniques can be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a spatial stream, and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0084] Beamforming, which can also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining the signals communicated by antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The combination of signals can be used to shape a signal in one or more desired directions, while attenuating the signal in other directions. The orientation of an antenna beam can be gauged by a directional parameter, such as a beam direction, a beam width, an angular resolution, or some other parameter. Directional parameters can be associated with a particular receiving device (e.g., a UE 115), with a particular transmitting device (e.g., a base station 105), with a particular beam, or with some other suitable entity.

[0085] A base station 105 or a UE 115 can use beamforming techniques as part of the beamforming operations. For example, a base station 105 can use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) can be transmitted by a base station 105 multiple times in different directions. For example, the base station 105 can transmit a signal according to different beamforming weight sets associated with different directions (e.g., directional parameters) relative to a transmitting device, such as the base station 105, or relative to some other suitable entity. Transmissions in different beam directions can be used to identify (e.g., by a transmitting device, such as the base station 105, or by a receiving device, such as the UE 115) a beam direction for the base station 105 to use for later transmissions or to use for receiving signals.

[0086] A base station 105 can transmit some signals, such as data signals associated with a particular receiving device, in a single beam direction (e.g., a direction associated with the receiving device, such as a UE 115). In some examples, the beam direction associated with transmissions along a single beam direction can be determined based on a signal that was transmitted in one or more beam directions. For example, a UE 115 can receive one or more of the signals transmitted by the base station 105 in different directions and can report an indication of the signal that the UE 115 received with a highest signal quality, or an otherwise acceptable signal quality, to the base station 105.

[0087] In some examples, transmissions by a device (e.g., base station 105 or UE 115) can be performed using multiple beam directions, and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station 105 to a UE 115). A UE 115 can report feedback that indicates precoding weights for one or more beam directions, and the feedback can correspond to a configured number of beams across a system bandwidth or one or more sub-bands. The base station 105 can transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS),) that can be precoded or unprecoded. A UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted in one or more directions by a base station 105, a UE 115 can employ similar techniques when transmitting signals in different directions (e.g., for identifying beam directions for subsequent transmission or reception by the UE 115) or transmitting a signal in a single direction (e.g., for transmitting data to a receiving device).

[0088] A receiving device (e.g., a UE 115) can try multiple receive configurations (e.g., directional listening) when receiving various signals from base stations 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device can try multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which can be referred to as “listening” according to different receive beams or receive directions. In some examples, a receiving device can use a single receive configuration to receive signals along a single beam direction (e.g., when receiving a data signal). The single receive configuration can be aligned with a determined beam direction based on listening according to different receive configuration directions (e.g., listening according to multiple beam directions, a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0089] Wireless communications system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP -based. A Radio Link Control (RLC) layer can perform packet segmentation and assembly to communicate over logical channels. A Medium Access Control (MAC) layer can perform priority handling and multiplexing of logical channels into transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both, to support MAC layer retransmissions to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a base station 105 or core network 130 supporting radio bearers for user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0090] The UEs 115 and the base stations 105 can support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique used to provide retransmission at the MAC layer. HARQ can include error detection techniques (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device can support same-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in a previous time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0091] Figure 2 An example of a wireless communications system 200 that supports techniques for managing uplink transmissions for power saving is shown, in accordance with aspects of the present disclosure. Wireless communications system 200 can implement aspects of wireless communications system 100. For example, wireless communications system 200 can include a base station 105-a and a UE 115-a, which can be examples of a base station 105 and a UE 115 as described herein. Wireless communications system 200 can also include a server 205, which can be an example of a server as described herein. Wireless communications system 200 can support multiple radio access technologies, including 4G systems such as LTE systems, LTE-A systems, or LTE-A Pro systems, and 5G systems, which can be referred to as NR systems. Wireless communications system 200 can include features for improved power saving, and in some examples, can facilitate high reliability and low latency XR-related transmissions for power saving, among other beneficial effects.

[0092] In Figure 2In the example of FIG. 2, base station 105-a and UE 115-a can support various types of applications that can have periodic or semi-periodic data traffic. Base station 105-a can be in wireless communication with a server 205, which can provide periodic or semi-periodic data traffic to base station 105-a for forwarding to UE 115-a. Server 205 can be a cloud server, a server associated with an application subscription provider, a proxy server, a web server, an application server, or any combination thereof. Server 205 can include an application distribution platform. The application distribution platform can allow UE 115-a to discover, browse, share, and download applications via base station 105-a, and thus provide digital distribution of applications from the application distribution platform. Digital distribution can thus be a form of delivering content such as data without using physical media but through an online delivery medium such as the Internet. For example, UE 115-a can upload or download applications for streaming, downloading, uploading, or processing data (e.g., images, audio, video). Server 205 can also send various information to UE 115-a, such as instructions or commands to download an application on UE 115-a via base station 105-a.

[0093] As an example, base station 105-a and UE 115-a can support XR applications, which can have periodic or semi-periodic XR data traffic. For XR-related applications, UE 115-a can generate pose information 210 as well as other control information 215 and send it to server 205 (e.g., a server hosting the XR application) via base station 105-a. Pose information 210 can define a pose, attitude, position, orientation, or movement of UE 115-a (or a user of UE 115-a) and can be acquired via imaging devices including a head-mounted unit (HMU), a head-mounted display (HMD), an external imaging device, or any combination thereof. Pose information 210 can thus include data on the degrees of freedom of movement of UE 115-a (or the user) and can be characterized by six degrees of freedom in which the user / object can change position (e.g., up / down translation, left / right translation, forward / backward translation, pitch, yaw, roll). Control information 215 can refer to other inputs or commands input by the user, such as movements / commands input using a joystick, controller, or other device. UE 115-a can additionally acquire scene information. Scene information can include images and / or video of the surrounding physical or virtual environment and can be acquired with pose information 210 or control information 215 or both in the context of the XR application.

[0094] Reference Figure 2At 220, UE 115-a can sample the pose information 210, control information 215, scene information, or any combination thereof. Thus, at 230, UE 115 can obtain information to send to server 205 and / or base station 115-a. For example, at 230, UE 115-a can sample pose 1. In some examples, pose information 210 and control information 215 can be obtained (e.g., sampled) at a data rate of approximately 0.5-2 Mbps and can be sent to server 205 approximately every 2 ms (e.g., 500 Hz). Further, pose information 210, control information 215, or both can be sampled and / or sent in a file size of 1 Kbits (e.g., 125 bytes) or 4 Kbits (e.g., 500 bytes). In contrast, scene information can be obtained (e.g., sampled) at a data rate of approximately 10 Mbps and can be sent to server 205 at a rate of 10 Hz. Further, scene information can be sampled and / or sent in a file size of 1 Mbits (e.g., 125 Kbytes) per 100 ms.

[0095] At 225, UE 115-a can send the sampled information (send pose 1) to server 205. In some aspects, UE 115-a can send the sampled information within a first uplink symbol after the time at which the information (e.g., pose information 210, control information 215, scene information) is sampled. At 230, the sampled information can be received at server 205. At 235, server 205 can render and encode a new XR frame based on (e.g., from) the received information (pose 1). In some aspects, the XR frame can be generated periodically and can be divided into multiple slices that are separately encoded. As shown, the age of the obtained information (e.g., age of pose 240) can be defined as the duration between when the information is sampled (e.g., pose 1 sampled at 220) and when the XR is rendered and / or encoded at server 205. Figure 2

[0096] At 245, the XR frame can be sent to base station 105-a. In some aspects, each encoded slice (of the file) of the XR frame can be separately sent from server 205 to base station 105-a. At 250, base station 105-a can send the received XR frame to UE 115-a. In some aspects, the slices of the XR frame can be sent to UE 115-a through multiple transport blocks or a burst of transport blocks. For example, as will be referred to herein with respect to FIG. 3, the XR frame can be sent to UE 115-a in a first transport block (TB) and a second TB. Figure 3 ​Further to the detailed discussion, the base station 105-a can transmit data to the UE 115-a via XR frame bursts 255 (e.g., first XR frame burst 255-a, second XR frame burst 255-b, and third XR frame burst 255-c). Each XR frame burst 255 can have a transmission delay requirement, and the downlink transmission from the base station 105-a to the UE 115-a can be characterized by a downlink delay budget 260. At 265, the UE 115-a can decode the data received from the base station 105-a (e.g., decode the XR frame bursts 255) and perform an asynchronous time warp procedure. Subsequently, at 270, the received XR frames can be displayed at the UE 115-a. Figure 2 An example of the motion-to-render-to-photon latency (e.g., motion-to-render photon latency 275) can be depicted.

[0097] In some cases, the transmission of pose information 210 by the UE 115-a can occur continuously and result in wasted power consumption. For example, the UE 115-a continuously transmits pose information 210 to the server 205 and / or the base station 105-a without any mechanism to reduce or control the transmission of pose information 210 to reduce power (e.g., enter a lower power mode). In the wireless communications system 200, the UE 115-a can be configured to provide power savings by managing the transmission of pose information as well as other control information transmissions. For example, the UE 115-a can be configured to generate and transmit pose information 210 when an XR frame burst (also referred to as a downlink burst) (e.g., a downlink frame transmission associated with an XR application) from the server 205 and / or the base station 105-a is occurring. This allows for alignment between uplink transmissions (e.g., pose information transmissions) and downlink receptions (e.g., frame receptions), which can reduce unnecessary wake-up periods and provide the UE 115-a with an opportunity to enter an extended sleep state. To support alignment between uplink transmissions and downlink receptions, the UE 115-a can be configured to synchronize an uplink transmission rate with an XR frame burst rate. The UE 115-a can also be configured to determine one or more slots relative to a downlink slot of an XR frame burst for transmitting pose information. Further details are provided herein with respect to Figures 3 to 9 Further advantages of the disclosure are described in further detail.

[0098] Figure 3 An example of a downlink and uplink configuration 300 that supports techniques for managing uplink transmissions for power savings is shown in accordance with aspects of the present disclosure. The downlink and uplink configuration 300 can implement or can be implemented by the wireless communications system 200 of FIG. 2, the base station 105 of FIG. 1, the UE 115 of FIG. 1, and / or aspects of the techniques described with reference to FIGs. 1-2 and 4-5. The downlink and uplink configuration 300 can support wireless communications at a base station 105, a UE 115, or both. Figure 1 and Figure 2Aspects of the described wireless communications systems 100 and 200 are implemented. The downlink and uplink configurations 300 can be based on a configuration of the base stations 105 and implemented by the UEs 115. The downlink and uplink configurations 300 can configure time resources (e.g., symbols, mini-slots, slots) and frequency resources (e.g., carriers, subcarriers). The downlink and uplink configurations 300 can support multiple radio access technologies, including 4G systems such as LTE systems, LTE-A systems, or LTE-A Pro systems, and 5G systems, which can be referred to as NR systems.

[0099] The base stations 105 can transmit and the UEs 115 can receive one or more frame bursts 305 carrying one or more frames associated with an application. For example, the base stations 105 can transmit and the UEs 115 can receive one or more XR frame bursts carrying one or more XR frames associated with an XR application. The frames can be divided into multiple slices that can be encoded individually. The base stations 105 can transmit the encoded slices over the air through multiple transport blocks (burst of transport blocks). In some examples, the base stations 105 can transmit the frame bursts 305 according to a periodicity 310 (e.g., a frame generation periodicity) that can be based on a frame rate (e.g., 60 Hz or 120 Hz frame rate, which provide a frame generation periodicity of 16.67 ms or 8.33 ms, respectively) of the application, such as an XR application. The UEs 115 can thereby receive the frame bursts 305 based on the periodicity 310. In Figure 3 In examples, there can be one or more power saving opportunities 315 between the frame bursts 305 for the UEs 115 to experience additional power savings.

[0100] The UEs 115 can determine the one or more power saving opportunities 315 between the frame bursts 305 based at least in part on the periodicity 310. For example, the UEs 115 can determine a power saving opportunity 315-a between two consecutive frame bursts (e.g., frame burst 305-a and frame burst 305-b). Additionally or alternatively, the UEs 115 can determine a power saving opportunity 315-b between two other consecutive frame bursts (e.g., frame burst 305-b and frame burst 305-c). However, in some cases, the UEs 115 can not be able to experience additional power savings associated with the one or more power saving opportunities 315 because the UEs 115 can continuously transmit pose information 320, which can result in wasted power consumption. For example, the UEs continuously transmit the pose information 210 to the base stations 105 without any mechanism to reduce or control the transmission of the pose information 210 to lower the power level 325 in dBm. As a result, the one or more power saving opportunities 315 between the frame bursts 305 go unused.

[0101] Figure 4An example of a downlink and uplink configuration 400 that supports techniques for managing uplink transmissions to conserve power is shown in accordance with aspects of the present disclosure. The downlink and uplink configuration 400 can be implemented or enabled by aspects of the wireless communications systems 100 and 200 described with reference to Figure 1 and Figure 2 The downlink and uplink configuration 400 can be based on a configuration of the base station 105 and implemented by a UE 115. The downlink and uplink configuration 400 can configure time resources (e.g., symbols, mini-slots, slots) and frequency resources (e.g., carriers, subcarriers) for downlink and uplink transmissions. The downlink and uplink configuration 400 can support multiple radio access technologies including 4G systems and 5G systems.

[0102] The base station 105 can transmit and the UE 115 can receive one or more frame bursts 405 carrying one or more frames associated with an application. For example, the base station 105 can transmit and the UE 115 can receive one or more XR frame bursts carrying one or more XR frames associated with an XR application (e.g., an AR application or a VR application). As described herein, a frame can be divided into multiple slices that can be encoded individually. The base station 105 can transmit the encoded slices over a channel (e.g., a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH)) through multiple transport blocks (a burst of transport blocks). In some examples, the base station 105 can transmit the frame burst 405 according to a periodicity 410 (e.g., a frame generation periodicity) that can be based on a frame rate (e.g., a 60 Hz or 120 Hz frame rate, which provide a 16.67 ms or 8.33 ms frame generation periodicity, respectively) of the application, such as an AR application or a VR application, and the UE 115 can receive the frame burst.

[0103] In Figure 4In examples of FIG. 4, one or more power saving opportunities 415 can occur between at least two of the frame bursts 405. These power saving opportunities 415 can provide additional power savings for the UE 115. In some examples, the UE 115 can determine the one or more power saving opportunities 415 between the frame bursts 405 based at least in part on the periodicity 410 associated with the base station 105. For example, the UE 115 can determine a power saving opportunity 415-a between two consecutive frame bursts (e.g., frame burst 405-a and frame burst 405-b). Additionally, or alternatively, the UE 115 can determine a power saving opportunity 415-b between two other consecutive frame bursts (e.g., frame burst 405-b and frame burst 405-c). To experience the benefits of the one or more power saving opportunities 415, the UE 115 can be configured to transmit the pose information 420 and / or other control information associated with the application (e.g., XR application) only during the frame bursts 405.

[0104] For example, the UE 115 can transmit the pose information 420 and / or other control information during the frame burst 405-a, the frame burst 405-b, or the frame burst 405-c, or any combination thereof. The UE 115 can refrain from transmitting the pose information 420 and / or other control information during the power saving opportunity 415-a or the power saving opportunity 415-b, or both. In Figure 4 In examples of FIG. 4, an uplink transmission rate associated with the pose information 420 is greater than or equal to a downlink transmission rate associated with the frame bursts 405 to enable timing alignment between uplink transmissions (e.g., pose information 420 transmissions) and downlink receptions (e.g., frame burst 405 receptions). The downlink transmission rate corresponds to a number of frame transmissions per second. The uplink transmission rate corresponds to a number of pose information transmissions per second. The downlink and uplink configuration 400 provides power savings for the UE 115 by reducing the power level from, for example, the first power level 425 to the second power level 430 during the power saving opportunities 415. The downlink and uplink configuration 400 can also provide occasions for the UE 115 to remain in an extended sleep mode (e.g., low power mode).

[0105] Figure 5 An example of a downlink and uplink configuration 500 that supports techniques for managing uplink transmissions for power saving is shown in accordance with aspects of the present disclosure. The downlink and uplink configuration 500 can implement or can be implemented by the downlink and uplink configurations 400 of FIG. 4, the downlink and uplink configurations 300 of FIG. 3, the base station 105 of FIG. 1, the UE 115 of FIG. 1, and / or aspects of the present disclosure. Figure 1 and Figure 2Aspects of the described wireless communications systems 100 and 200 are implemented. Downlink and uplink configurations 500 can be based on a configuration of a base station 105 and implemented by a UE 115. The downlink and uplink configurations 500 can configure time resources (e.g., symbols, mini-slots, slots) and frequency resources (e.g., carriers, subcarriers) for downlink and uplink transmissions. The downlink and uplink configurations 500 can support multiple radio access technologies including 4G systems and 5G systems.

[0106] The base station 105 can transmit and the UE 115 can receive one or more frame bursts 505 carrying one or more frames associated with an application. For example, the base station 105 can transmit and the UE 115 can receive one or more XR frame bursts carrying one or more XR frames associated with an XR application. In some examples, the base station 105 can transmit the frame bursts 505 and the UE 115 can receive the frame bursts according to a periodicity 510 (e.g., a frame generation periodicity), which can be based on a frame rate (e.g., a 60 Hz or 120 Hz frame rate, which provide a frame generation periodicity of 16.67 ms or 8.33 ms, respectively) of the application, such as the XR application.

[0107] One or more power saving opportunities 515 can occur between at least two frame bursts 505. For example, the UE 115 can determine a power saving opportunity 515-a between two consecutive frame bursts (e.g., frame burst 505-a and frame burst 505-b). Additionally or alternatively, the UE 115 can determine a power saving opportunity 515-b between two other consecutive frame bursts (e.g., frame burst 505-b and frame burst 505-c). These power saving opportunities 515 can provide additional power savings for the UE 115. In Figure 5 In examples, to experience the benefits of the one or more power saving opportunities 515, the UE 115 can be configured to transmit pose information 520 and / or other control information associated with the application (e.g., the XR application) only once during a frame burst 505. The UE 115 can adjust an uplink transmission rate associated with the pose information 520 based at least in part on a downlink transmission rate associated with the frame burst 505. For example, the UE 115 can reduce the uplink transmission rate to match the downlink transmission rate.

[0108] UE 115 can additionally or alternatively adjust an uplink pose generation rate associated with the pose information 520, for example, based at least in part on the adjusted uplink transmission rate. UE 115 can adjust the uplink pose generation rate because uplink transmissions (e.g., associated with the pose information 520) can consume a large amount of power, particularly when UE 115 is located at a cell edge of a base station 105 or is in a low geometry condition. In some examples, UE 115 can reduce its pose information generation rate to the downlink frame generation rate. In this way, the adjusted uplink pose generation rate matches the downlink frame generation rate associated with the frame burst 505.

[0109] Accordingly, UE 115 can transmit the pose information 520 and / or other control information once during the frame burst 505-a, the frame burst 505-b, or the frame burst 505-c, or any combination thereof. UE 115 can refrain from transmitting the pose information 520 and / or other control information during the power saving opportunity 515-a or the power saving opportunity 515-b, or both. The downlink and uplink configuration 500 provides power saving for UE 115 by reducing the power level from, for example, the first power level 525 to the second power level 530 during the power saving opportunity 515. The downlink and uplink configuration 500 can also provide UE 115 with opportunities to remain in an extended sleep mode (e.g., low power mode).

[0110] Figure 6 An example of a downlink and uplink configuration 600 that supports techniques for managing uplink transmissions for power saving is shown in accordance with aspects of the present disclosure. The downlink and uplink configuration 600 can implement or can be implemented by aspects of the wireless communications systems 100 and 200 described with reference to Figure 1 and Figure 2 The downlink and uplink configuration 600 can be based on a configuration of a base station 105 and implemented by a UE 115. The downlink and uplink configuration 600 can configure time resources (e.g., symbols, mini-slots, slots) and frequency resources (e.g., carriers, subcarriers) for downlink and uplink transmissions. The downlink and uplink configuration 600 can support multiple radio access technologies, including 4G systems and 5G systems.

[0111] The base stations 105 can transmit and the UEs 115 can receive one or more frame bursts 605 carrying one or more frames associated with an application. For example, the base stations 105 can transmit and the UEs 115 can receive one or more XR frame bursts carrying one or more XR frames associated with an XR application. In some examples, the base stations 105 can transmit frame bursts 605 according to a periodicity 610 (e.g., a frame generation periodicity), and the UEs 115 can receive the frame bursts, which can be based on a frame rate of the application, such as an XR application. One or more power saving opportunities 615 can occur between at least two frame bursts 605. For example, the UE 115 can determine a power saving opportunity 615-a between two frame bursts (e.g., frame burst 605-a and frame burst 605-b). Additionally or alternatively, the UE 115 can determine a power saving opportunity 615-b between two other frame bursts (e.g., frame burst 605-b and frame burst 605-c). These power saving opportunities 615 can provide additional power savings for the UE 115.

[0112] In Figure 6 example, to take advantage of the benefits of the one or more power saving opportunities 615, the UE 115 can be configured to generate and combine multiple consecutively generated poses and / or control information 620 and transmit the combined multiple consecutive poses and / or control information 620 only once during a frame burst 605. In some examples, the UE 115 can transmit the combined multiple consecutive poses and / or control information 620 only once during a frame burst 605 at a reduced rate. If the uplink transmission rate associated with the poses and / or control information is reduced (e.g., from 500 Hz to 60 Hz), the base station 105 can be configured with a pose prediction algorithm to improve pose prediction when rendering new frames. In some examples, the base station 105 can configure the UE 115 to transmit the combined multiple consecutive poses and / or control information 620 at a particular uplink transmission rate or a particular uplink periodicity. For example, in Figure 6 example, the UE 115 can be configured to combine at least three consecutively generated poses and / or control information 620 and transmit it at 60 Hz (or a periodicity of 16.67 ms).

[0113] Accordingly, the UE 115 can transmit the combined multiple consecutive postures and / or control information 620 once during the frame burst 605-a, the frame burst 605-b, or the frame burst 605-c, or any combination thereof. The UE 115 can refrain from transmitting the combined multiple consecutive postures and / or control information 620 during the power saving opportunity 615-a or the power saving opportunity 615-b, or both. The downlink and uplink configuration 600 provides power saving for the UE 115 by reducing the power level from, for example, the first power level 625 to the second power level 630 during the power saving opportunity 615. The downlink and uplink configuration 600 can also provide occasions for the UE 115 to remain in an extended sleep mode (e.g., low power mode). In some examples, the UE 115 can also be configured to enable a timer based on the one or more frame bursts 605. For example, the UE 115 can switch from a first power mode to a second power mode based at least in part on the enabled timer, and switch back to the first power mode based on the timer expiring.

[0114] Figure 7 An example of a downlink and uplink slot format 700 that supports techniques for managing uplink transmissions for power saving in accordance with aspects of the present disclosure is shown. The downlink and uplink slot format 700 can be implemented or can be implemented by aspects of the wireless communications systems 100 and 200 described with reference to FIGs. 1 and 2, respectively. The downlink and uplink slot format 700 can be based on a configuration of a base station 105 and implemented by a UE 115. The downlink and uplink slot format 700 can configure time resources (e.g., symbols, mini-slots, slots) and frequency resources (e.g., carriers, subcarriers) for downlink and uplink transmissions. The downlink and uplink slot format 700 can support multiple radio access technologies, including 4G systems and 5G systems. Figure 1 and Figure 2 The downlink and uplink slot format 700 can be based on a configuration of a base station 105 and implemented by a UE 115. The downlink and uplink slot format 700 can configure time resources (e.g., symbols, mini-slots, slots) and frequency resources (e.g., carriers, subcarriers) for downlink and uplink transmissions. The downlink and uplink slot format 700 can support multiple radio access technologies, including 4G systems and 5G systems.

[0115] The base station 105 can transmit and the UE 115 can receive at least one frame burst 705 carrying one or more frames associated with an application. For example, the base station 105 can transmit and the UE 115 can receive at least one XR frame burst carrying one or more XR frames associated with an XR application. In Figure 7 To achieve the beneficial effects of power saving, the UE 115 can be configured to determine a start period 710 associated with an earliest transport block transmission of the one or more transport block transmissions associated with the frame burst 705. That is, the UE 115 can determine a most recent (or current) frame burst start time. This can correspond to a most recent downlink transmission arrival time (of the frame burst 705), which can correspond to an earliest downlink slot of the frame burst 705 in the downlink and uplink slot format 700.

[0116] In some examples, to increase the probability of overlap between downlink and uplink transmissions, which minimizes UE 115 wake-up time, the UE 115 can start the uplink transmission in the earliest time slot after the latest (or current) frame burst start time. For example, the UE 115 can determine the earliest uplink time slot 715 after the start period associated with the earliest transport block transmission of the frame burst 705. The UE 115 can transmit the pose and / or control information to the base station 105 in the earliest uplink time slot 715. In some examples, the start period 710 associated with the earliest transport block transmission of the frame burst 705 can correspond to the start of an active DRX duration (e.g., a DRX ON duration). The active DRX duration can also be configured to align with the expected start period (e.g., start period 710) of the earliest transport block transmission of the frame burst 705. In some examples, the start period 710 (e.g., a downlink burst start time) can be determined as the earliest downlink time slot at the UE 115 to start receiving the current burst (e.g., frame burst 705). In some cases, the first time slot at which a downlink frame associated with the frame burst 705 arrives at the UE 115 can vary according to jitter or encoding delay.

[0117] Accordingly, the UE 115 can be configured to determine an uplink time slot to transmit the pose and / or control information during the frame burst 705. By controlling the power level (e.g., the downlink reception power level 720 and the uplink transmission power level 725) during the power saving opportunity associated with the frame burst 705, the UE 115 can experience additional power savings.

[0118] Figure 8 An example of a downlink and uplink slot format 800 that supports techniques for managing uplink transmissions for power saving in accordance with aspects of the present disclosure is shown. The downlink and uplink slot format 800 can implement or can be implemented by aspects of the wireless communications systems 100 and 200 described with reference to Figure 1 and Figure 2 The downlink and uplink slot format 800 can be based on a configuration of the base station 105 and implemented by the UE 115. The downlink and uplink slot format 800 can configure time resources (e.g., symbols, mini-slots, slots) and frequency resources (e.g., carriers, subcarriers) for downlink and uplink transmissions. The downlink and uplink slot format 800 can support multiple radio access technologies, including 4G systems and 5G systems.

[0119] The base station 105 can transmit and the UE 115 can receive at least one frame burst 805 carrying one or more frames associated with an application. For example, the base station 105 can transmit and the UE 115 can receive at least one XR frame burst carrying one or more XR frames associated with an XR application. In Figure 8 In examples, to realize the beneficial effects of power saving, the UE 115 can be configured to determine one or more uplink slots (e.g., the earliest uplink slot 815) prior to an earliest downlink slot associated with an earliest transport block transmission (which can begin at the start period 810) of the one or more transport block transmissions associated with the frame burst 805. The UE 115 can be configured to transmit pose and / or control information to the base station 105 during the one or more uplink slots prior to the earliest downlink slot associated with the earliest transport block transmission.

[0120] In some examples, the UE 115 can transmit the pose and / or control information in the one or more uplink slots based at least in part on satisfying a slot window threshold. That is, if there is one or more prior uplink slots within a time window prior to the most recent (current) downlink slot, the UE 115 can transmit the pose and / or control information in the one or more prior uplink slots. The slot window threshold can be configurable. For example, the slot window threshold can be 1 or 2 slots (or 0.5 ms, 1 ms, or 2 ms). This can ensure that the uplink and downlink transmissions are immediate, which can reduce power consumption of the UE 115. Thus, the UE 115 can be configured to control power levels (e.g., the downlink reception power level 820 and the uplink transmission power level 825) during the power saving opportunity associated with the frame burst 805 to experience additional power savings.

[0121] Figure 9 A process flow 900 that supports techniques for managing uplink transmissions for power saving in accordance with aspects of the present disclosure is shown. The process flow 900 can implement aspects of the wireless communications system 100 and the wireless communications system 200 described with reference to Figure 1 and Figure 2 The process flow 900 can be implemented based on configurations of the base station 105-b and implemented by the UE 115-b to facilitate power saving (e.g., entering a low power mode) of the UE 115-b by managing transmission of pose information during a downlink burst occasion. The process flow 900 can also be implemented based on configurations of the base station 105-b and implemented by the UE 115-b to facilitate high reliability and low latency XR-related operations (e.g., determining a position and orientation of the UE 115-b (or user) in space relative to real and virtual environments) and other beneficial effects.

[0122] In the description of the process flow 900 below, the operations between the base station 105-b and the UE 115-b can be transmitted in a different order than the example shown, or the operations performed by the base station 105-b and the UE 115-b can be performed in different orders or at different times. Some operations can also be left out of the process flow 900, and other operations can be added to the process flow 900. The base station 105-b and the UE 115-b can be examples of the base stations 105 and UEs 115 described with reference to Figure 1 and Figure 2 respectively.

[0123] At 905, the base station 105-b can transmit, to the UE 115-b, one or more XR frames associated with an XR application, for example, during a downlink burst occasion. At 910, the UE 115-b can determine a downlink burst occasion for the XR application and receive, from the base station 105-b, one or more XR frames associated with the XR application. At 915, the UE 115-b can generate pose information. For example, the UE 115-b can generate pose information associated with the UE 115-b and the XR application. At 920, the UE 115-b can transmit, to the base station 105-b, the pose information during the downlink burst occasion. In some examples, the UE 115-b can enable a timer (e.g., an active timer, an inactive timer) based at least in part on the downlink burst occasion, and the UE 115-b can switch from a first operational state to a second operational state based at least in part on the enabled timer. In some cases, the first operational state corresponds to a first power level that is lower than a second power level associated with the second operational state.

[0124] Figure 10 A block diagram 1000 of a device 1005 that supports techniques for managing uplink transmissions for power saving in accordance with aspects of the present disclosure is shown. The device 1005 can be an example of aspects of a UE 115 as described herein. The device 1005 can include a receiver 1010, a UE communications manager 1015, and a transmitter 1020. The device 1005 can also include at least one processor. Each of these components can be in communication with one another (e.g., via one or more buses).

[0125] The receiver 1010 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to techniques for managing uplink transmissions for power saving). Information can be passed on to other components of the device 1005. The receiver 1010 can be an example of aspects of the transceiver 1320 described with reference to Figure 13 The receiver 1010 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to techniques for managing uplink transmissions for power saving). Information can be passed on to other components of the device 1005. The receiver 1010 can be an example of aspects of the transceiver 1320 described with reference to

[0126] The UE communications manager 1015 can be implemented as an integrated circuit or chipset for the device 1005, and the receiver 1010 and transmitter 1020 can be implemented as analog components (e.g., amplifiers, filters, antennas) coupled with a modem of the device 1005 to enable wireless transmission and reception. The actions performed by the UE communications manager 1015 as described herein can be implemented to realize one or more potential advantages. At least one implementation can enable the UE communications manager 1015 to manage transmission of pose information during a downlink burst occasion. For example, the UE communications manager 1015 can determine a downlink burst occasion for an XR application, generate pose information associated with the device 1005 and the XR application, and transmit the pose information during the downlink burst occasion. The UE communications manager 1015 can be an example of aspects of the UE communications manager 1310 described herein. Based on implementing management of transmission of pose information, one or more processors of the device 1005 (e.g., a processor that controls or is combined with the UE communications manager 1015) can facilitate improvements in power savings, and in some examples, higher reliability and lower latency XR-related operations, among other beneficial effects.

[0127] The UE communications manager 1015, or its sub-components, can be implemented in hardware, software (e.g., code executed by at least one processor), or a combination thereof. If implemented in code executed by at least one processor, the functions of the UE communications manager 1015, or its sub-components, can be executed by a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described in the present disclosure.
