Adaptive Configurable Authorization for Power Saving

Abstract

Methods, systems, and apparatus for wireless communication are described. A user equipment (UE) can receive an authorized configuration comprising multiple sets of parameters, and the UE can select a set of parameters from the configured authorization based on channel conditions. In some examples, the UE can be configured to signal the selected set of parameters and its corresponding parameter values ​​to a network (e.g., a base station). For example, the UE can be configured to signal the selected set of parameters via semi-static signaling (e.g., Radio Resource Control (RRC) message transmission) or dynamic signaling (e.g., Media Access Control-Control Element (MAC-CE) message transmission, Uplink Control Information (UCI) message transmission, etc.). By configuring the UE with multiple sets of parameters, the UE can adapt to changing channel conditions, which can provide higher reliability and lower latency for wireless communication, as well as reduce the UE's power consumption.

Technical Field

[0003] The following text relates to wireless communication, and more specifically, to adaptive configurable licensing for power saving. 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 able to support 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-Advanced (LTE-A) systems, or LTE-A Pro systems), and fifth-generation (5G) systems, which can 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 Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM).

[0005] Wireless multiple access communication systems may include one or more base stations or one or more network access nodes. Each base station or node simultaneously supports communication from multiple communication devices, which may also be referred to as User Equipment (UE). 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 attitude information and other control information to avoid visual conflicts, such as object misalignment between real and virtual environments, and other visual clashes. In some cases, the transmission of attitude information and other control information by these communication devices may be affected by changes in channel conditions. Therefore, for power saving, it may be desirable to manage downlink reception and uplink transmission associated with XR applications, and other examples. Summary of the Invention

[0006] Various aspects of this disclosure relate to configuring communication devices, such as UEs and base stations, such as eNodeBs (eNBs), next-generation NodeBs, or gigabit NodeBs (any of which may be referred to as gNBs) of a wireless communication system, to support authorized configurations (also known as configured authorization) that include multiple sets of parameters. The parameter sets may include, but are not limited to, repetition factor values, modulation and coding scheme (MCS) index values, transport block size (TBS) index values, number of layers, number of antenna ports, precoding matrix indicator (PMI) index values, etc. In some cases, channel conditions (e.g., link quality) may vary and negatively impact downlink reception and uplink transmission associated with XR applications. The UE can be configured to select a set of parameters from the configured authorization based on channel conditions. Therefore, the UE can adapt to changing channel conditions, which can improve the reliability of downlink reception and uplink transmission and reduce UE power consumption. Thus, among other benefits, this disclosure can also facilitate highly reliable and low-latency XR-related operation.

[0055] Some wireless communication systems may include communication devices, such as UEs and base stations, that can support multiple radio access technologies, such as eNBs, next-generation NodeBs, or gigabit NodeBs (all of which can be referred to as gNBs). 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, which can have periodic or half-cycle data traffic. As described herein, applications can be hosted by a server. The server can transmit periodic or half-cycle data traffic to the base station, which can forward the data traffic to the UE. The base station can forward data traffic to the UE using multiple TBs (also known as TB bursts).

[0056] In XR applications, features from both real and virtual environments can be overlaid and displayed to the user for consumption via the UE. To avoid visual conflicts, such as object misalignment from real and virtual environments, and other visual clashes, the UE can sense, generate, and transmit attitude information to the network (e.g., a base station, a server hosting the XR application). Attitude information defines the UE's (or user's) position and orientation in space relative to the real and virtual environments. The UE can transmit attitude information and / or other control information based on configured authorization. Configurable authorization can allocate resources (also called configured authorized resources) that the UE can use for downlink reception or uplink transmission, or both. Configurable authorization can be activated according to one or more schemes. In some examples, the base station can activate configured authorization for the UE via RRC signaling (e.g., configured authorization type 1). In other examples, the base station can activate or deactivate configured authorization for the UE via RRC signaling and L1 / L2 control signaling (e.g., MAC-CE signaling) (e.g., configured authorization type 2).

[0057] In some cases, a configuration license can configure a single set of parameters for the UE to use when transmitting attitude information and / or other control information to the network. However, in other cases, channel conditions (e.g., link quality) between the UE and the network may change, and these parameter sets may no longer be suitable for use when communicating with the network. Because the UE operates based on a single set of parameters provided in the configuration license, the UE does not possess any mechanism to adapt to changing channel conditions to improve reliability and reduce latency for XR applications. Various aspects of this disclosure relate to configuring the UE using a configuration license that includes multiple sets of parameters, and the UE can select a set of parameters from the configuration license based on channel conditions. Therefore, the UE can adapt to changing channel conditions, which can improve reliability for XR applications and reduce UE power consumption.

[0058] In some examples, the UE can be configured to signal to the network the selected set of parameters and their corresponding parameter values. For example, the UE can be configured to signal the selected set of parameters via semi-static signaling (e.g., RRC message transmission) or dynamic signaling (e.g., MAC-CE message transmission). In some examples, for dynamic signaling, the UE multiplexes a message carrying a dynamic indication of the selected set of parameters with the current uplink data transmission. In some examples, the network can signal to the UE the selection of the parameter set based on channel state feedback or measurement reports from the UE.

[0059] Aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential improvements, and others. The technology employed by the UE can provide benefits and enhancements to the operation of the UE. For example, operations performed by the UE can provide power-saving improvements to the UE. In some examples, configuring the UE to select a set of parameters based on channel conditions can reduce the UE's power consumption. In some other examples, configuring the UE to select a set of parameters based on channel conditions can facilitate higher reliability and lower latency XR-related operation, among other benefits.

[0060] The aspects of this disclosure are initially described in the context of wireless communication systems. These aspects are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to adaptive configuration licensing for power saving.

[0061] Figure 1An example of an adaptively configured, power-saving wireless communication system 100 supporting aspects of this disclosure is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or an NR network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0062] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, on which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0063] UE 115 can be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile at different times, or both. UE 115 can be devices of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, Integrated Access And Backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown.

[0064] Base station 105 may communicate with core network 130, communicate with each other, or both simultaneously. For example, base station 105 may interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) or simultaneously via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links. The one or more base stations 105 described herein may include or may be referred to by those skilled in the art as base transceiver station, radio base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB or gigabit NodeB (any of which may be referred to as gNB), home NodeB, home eNodeB, or other suitable terms.

[0065] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a Wireless Local Loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or Machine Type Communication (MTC) device, and other examples, which may be implemented in various objects such as appliances or vehicles, meters, etc. The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s that may sometimes act as relays, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.

[0066] UE 115 and base station 105 can wirelessly communicate with each other via one or more carriers through one or more communication links 125. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the radio spectrum band (e.g., a bandwidth part (BWP)) operating according to one or more physical layer channels of a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with UE 115. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.

[0067] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling for coordinating the operation of other carriers. A carrier may 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 located according to a channel grating for discovery by UE 115. A carrier may operate in standalone mode, where initial acquisition and connection can be performed by UE 115 via the carrier, or in non-standalone mode, where the connection is anchored using different carriers (e.g., the same or different radio access technologies).

[0068] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. A carrier may carry either downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode). A carrier may be associated with a specific bandwidth of the radio spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of several bandwidths determined for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115, which supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0069] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread spectrum OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can consist of one symbol period (e.g., the duration of a 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). Therefore, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate of the UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity of communication with the UE 115.

[0070] One or more parameter sets (numerologies) of a carrier can be supported, where the parameter sets may include subcarrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP of a carrier can be active at a given time, and communication of UE 115 can be limited to one or more active BWPs. The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, which may, for example, refer to T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max N can represent the maximum supported subcarrier spacing. f This can represent the maximum supported Discrete Fourier Transform (DFT) size. Communication resources can be organized into time intervals based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0071] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into multiple time slots. Optionally, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix pre-added to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or operating frequency band. A subframe, time slot, micro-time slot, or symbol may be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and may be referred to as the Transmission Time Interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0072] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region (e.g., a control resource set (CORESET)) of the physical control channel can be defined by multiple symbol periods and can be extended 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 UEs 115 can monitor or search for control information in the control region based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format with a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115, and a UE-specific search space set used to send control information to a particular UE 115.

[0073] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., via a carrier) and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), and others). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of base station 105), the range of these cells can range from small areas (e.g., buildings, subsets of buildings) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, and other examples.

[0074] Macro cells cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access for UEs 115 that subscribe to services from network providers supporting macro cells. In contrast, small cells can be associated with lower-power base stations 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UEs 115 that subscribe to services from network providers, or restricted access to UEs 115 associated with small cells (e.g., UEs 115 in a Closed Subscriber Group (CSG), or UEs 115 associated with a user in a home or office). Base station 105 can support one or more cells and can also use one or more component carriers to support communication on one or more cells. In some examples, carriers can support multiple cells and can be configured with different cells based on different protocol types that can provide access to different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0075] Base station 105 can be mobile, thus providing communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0076] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 may be time-disaligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0077] Some UE 115 devices, such as MTC or IoT devices, may be low-cost or low-complexity devices that can provide 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 each other or with base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application, which uses the information or presents it to people interacting with the application. Some UE 115 devices may be designed to collect information or automate the 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.

[0078] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., supporting unidirectional communication via transmission or reception, but not simultaneous transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UE 115s include entering a power-saving deep sleep mode when not engaged in active communication, operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside the carrier.

[0079] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private 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 prioritizing services, which can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0080] Base station 105 and UE 115 can support various types of applications that may have periodic or semi-periodic data services. Base station 105 can wirelessly communicate with a server (not shown) that can provide periodic or semi-periodic data services to base station 105 for forwarding to UE 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 may include an application distribution platform. The application distribution platform can allow UE 115 to discover, browse, share, and download applications via base station 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 using physical media but via online transmission media (such as the Internet). For example, UE 115 can upload or download applications for streaming, downloading, uploading, or processing data (e.g., images, audio, video). The server can also transmit various information to UE 115, such as instructions or commands to download applications on UE 115 via base station 105.

[0081] For example, base station 105 and UE 115 can support XR applications, which can have periodic or half-period XR data services. XR applications can support various frame rates, such as 60MHz or 120MHz. The server can generate XR frames at 60MHz, corresponding to a period of 16.67ms. Alternatively, the server can generate XR frames at 120MHz, corresponding to a period of 8.33ms. The server can transmit periodic or half-period XR data services to base station 105, which can then forward the XR data services to UE 115. The server can divide the XR data service into multiple slices (also called files), encode each slice, and transmit the encoded slices to base station 105. Base station 105 can use multiple TBs (also called TB bursts) to forward the XR data service to UE 115.

[0082] For XR applications, features from both the real and virtual environments can be overlaid and displayed to the user for consumption via UE 115. To avoid visual clashes, such as object misalignment from the real and virtual environments, and other visual conflicts, UE 115 can generate pose information and send it to the network (e.g., the server hosting the XR application). The pose information defines the position and orientation of the UE 115 (or the user) in space relative to the real and virtual environments. In some cases, different applications may have different uplink data streams.

[0083] For VR applications, a single uplink data stream may exist. For example, the UE 115 can generate attitude information (e.g., six-degree-of-freedom (6DOF) attitude information) and other control information. In some examples, the UE 115 can generate or transmit attitude information based on the data rate (e.g., 0.5-2 Mbps). The UE 115 can transmit attitude information and other control information based on the uplink transmission cycle (e.g., 2 ms (500 Hz)). In some examples, the attitude information and other control information can have different file sizes (e.g., 0.5 Mbit / 500 = 1 Kbit = 125 bytes, 2 Mbit / 500 = 4 Kbit = 500 bytes). The uplink data flow (FDP) can be from 1.25 ms to 10 ms.

[0084] For AR applications, there may be two uplink data streams. As part of the first uplink data stream, UE 115 can generate attitude information (e.g., 6DOF attitude information) and other control information. UE 115 can generate or transmit attitude information based on a data rate (e.g., 0.5-2 Mbps). UE 115 can transmit attitude information and other control information based on an uplink transmission period (e.g., 2 ms (500 Hz)). Similarly, for AR applications, the FDP can be 1.25 ms to 10 ms. As part of the second uplink data stream, UE 115 can generate attitude information for scene updates associated with the AR application. For scene updates, UE 115 can generate or transmit attitude information based on a data rate (e.g., 10 Mbps at 10 Hz). In some examples, the attitude information can have different file sizes (e.g., 1 Mbits = 125 kbytes per 100 ms). The FDB might be 100 ms.

[0085] UE 115 can benefit from periodic or half-cycle data traffic, and more specifically, from the transmission latency between TB bursts carrying periodic or half-cycle data traffic, to implement various operations to reduce power consumption. UE 115 can transmit attitude information and / or other control information according to a configured authorization, which in some cases allows the UE 115 to configure a single set of parameters for use when transmitting attitude information and / or other control information to the network. However, in some cases, channel conditions (e.g., link quality) between the UE 115 and the network may change, and these parameter sets may no longer be suitable for use when communicating with the network. Because UE 115 operates based on a single set of parameters provided in the configured authorization, UE 115 does not possess any mechanism to adapt to changing channel conditions to improve reliability and reduce latency for XR applications.

[0086] Various aspects of this disclosure relate to configuring UE 115 using a configured authorization that includes multiple sets of parameters, and UE 115 can select the parameter sets from the configured authorization based on channel conditions via UE Communication Manager 102. Therefore, UE 115 can adapt to changing channel conditions via UE Communication Manager 102, which can improve reliability and reduce power consumption of UE 115 for XR applications. In some examples, UE 115 can be configured to signal the selected parameter sets and their corresponding parameter values ​​to the network via UE Communication Manager 102. For example, UE 115 can be configured to signal the selected parameter sets via semi-static signaling (e.g., RRC message transmission) or dynamic signaling (e.g., MAC-CE message transmission, etc.). In some examples, for dynamic signaling, UE 115 multiplexes a message carrying a dynamic indication of the selected parameter sets with the current uplink data transmission via UE Communication Manager 102. In some examples, the network can signal the selection of parameter sets to UE 115 based on channel state feedback from the UE or measurement reports from UE 115.

[0087] UE 115 can also communicate directly with other UE 115 via a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in the group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates resource scheduling for D2D communication. In other cases, D2D communication is performed between UE 115s without the involvement of base station 105.

[0088] D2D communication link 135 may be an example of a communication channel (such as a lateral link communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using Vehicle-to-Everything (V2X) communication, Vehicle-to-Vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signal control, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in the V2X system may communicate with roadside infrastructure (e.g., roadside units) or communicate with the network via one or more network nodes (e.g., base station 105) using Vehicle-to-Network (V2N) communication, or communicate with both.

[0089] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an Evolved Packet Core (EPC) or a 5G Core (5GC), and may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access And Mobility Management Function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) routing packets or interconnects to external networks. The control plane entity can manage non-access stratum (NAS) functions of UE 115 served by base station 105 associated with core network 130, such as mobility, authentication, and bearer management. User IP packets can be transmitted through a user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranet(s), IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0090] Some network devices (such as base station 105) may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmission entities 145, which may be referred to as a radio headend, smart radio headend, or transmission / reception point (TRP). Each access network transmission entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0091] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is referred to as the Ultra-High Frequency (UHF) region or decimeter band (because the wavelength range is from approximately one decimeter to one meter). UHF waves may be blocked or deflected by buildings and environmental features, but these waves can penetrate structures sufficiently to allow a macrocell to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the High Frequency (HF) or Very High Frequency (VHF) portion of the spectrum below 300 MHz, UHF wave transmissions may be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0092] The wireless communication system 100 can also operate in the Super High Frequency (SHF) region (also known as the centimeter band) using the 3 GHz to 30 GHz frequency band, or in the Extremely High Frequency (EHF) region of the spectrum (e.g., 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of an in-device antenna array. However, compared to SHF or UHF transmissions, EHF transmissions may suffer greater atmospheric attenuation and shorter range. The techniques disclosed herein can be used in transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary by country or regulatory body.

[0093] Wireless communication system 100 can utilize licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 can use Licensed Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on carrier aggregation configurations combined with component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.

[0094] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be located together at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports, which base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming of signals transmitted via antenna ports.

[0095] Base station 105 or UE 115 can use MIMO communication to leverage multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique can be referred to as spatial multiplexing. For example, multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate 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 technology includes Single-User MIMO (SU-MIMO) and Multiple-User MIMO (MU-MIMO). In Single-User MIMO, multiple spatial layers are transmitted to the same receiving device, while in MU-MIMO, multiple spatial layers are transmitted to multiple devices.

[0096] Beamforming, also known as spatial filtering, directional transmission, or directional reception, is a signal processing technique used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a particular orientation of the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include the transmitting or receiving device applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element can be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0097] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) for beamforming operations to enable directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals based on different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device such as base station 105, or by a receiving device such as UE 115) the beam direction for later transmission or reception by base station 105.

[0098] Base station 105 may transmit signals, such as data signals associated with a specific receiving device, in a single beam direction (e.g., the direction associated with a receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0099] In some examples, transmission by a device (e.g., base station 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and this feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may be precoded or uncoded. UE 115 may provide feedback for beam selection, which may be PMI or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection codebook). Although these techniques are described in reference base station 105 for signals transmitted in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam direction for UE 115 to subsequently transmit or receive) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0100] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, a receiving device (e.g., directional listening) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of which can be referred to as "listening"), depending on the different receiving configuration or receiving direction. In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). Depending on the different receive configuration orientation (e.g., based on the beam orientation determined by listening to multiple beam orientations to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality), a single receive configuration can be aligned in the beam orientation determined by listening.

[0101] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication over logical channels. The Medium Access Control (MAC) layer can perform priority processing and multiplexing logical channels into transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or the core network 130 supporting user plane data radio bearers. At the physical layer, transport channels can be mapped to physical channels.

[0102] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception over communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), Forward Error Correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). Under adverse radio conditions (e.g., low signal-to-noise ratio conditions), HARQ can improve throughput at the MAC layer. In some examples, the device can support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in the previous symbol within that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0103] Figure 2 An example of an adaptively configured, licensed wireless communication system 200 supporting power saving according to aspects of this disclosure is shown. Wireless communication system 200 may implement one or more aspects of wireless communication system 100, or be implemented by one or more aspects of wireless communication system 100. For example, wireless communication system 200 may include base station 105-a and UE 115-a, which may be examples of base station 105 and UE 115 as described herein. Wireless communication system 200 may also include server 205, which may be an example of a server as described herein. Wireless communication system 200 may support various radio access technologies, including 4G systems (e.g., LTE systems, LTE-A systems, or LTE-A Pro systems) and 5G systems (which may be referred to as NR systems). Wireless communication system 200 may include features for improving power saving, and in some examples, may facilitate high reliability and low latency uplink operation for power saving, among other benefits.

[0104] exist Figure 2In the example, base station 105-a and UE 115-a can support various types of applications that may have periodic or semi-periodic data services. Base station 105-a can wirelessly communicate with server 205, which can provide periodic or semi-periodic data services 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 may 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. In this way, digital distribution can be a form of delivering content (such as data) without using physical media but via online transmission media (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 transmit various information to UE 115-a, such as instructions or commands for downloading applications on UE 115-a via base station 105-a.

[0105] For example, base station 105-a and UE 115-a can support XR applications, which can have periodic or half-cycle XR data services. For XR-related applications, UE 115-a can generate attitude information 210 and other control information 215, and send the attitude information 210 and other control information 215 to server 205 (e.g., a server hosting the XR application) via base station 105-a. The attitude information 210 can define the attitude, pose, position, orientation, or movement of UE 115-a (or the user of UE 115-a), and can be obtained via imaging devices including head-mounted units (HMU), head-mounted displays (HMD), external imaging devices, or any combination thereof. Attitude information 210 may thus include data on the degrees of freedom of movement of UE 115-a (or the user), and may be characterized by the six degrees of freedom by which the user / object can change position (e.g., translation up / down, translation left / right, translation forward / backward, pitch, yaw, roll). Control information 215 may refer to other inputs or commands from the user, such as movement / commands using a joystick, controller, or other device. UE 115-a may additionally acquire scene information. Scene information may include images and / or video of the surrounding physical or virtual environment, and may be acquired in the context of an XR application along with attitude information 210 or control information 215, or both.

[0106] refer to Figure 2UE 115-a can sample attitude information 210, control information 215, scene information, or any combination thereof at 220. Thus, UE 115 can acquire information to be transmitted to server 205 and / or base station 115-a at 230. For example, UE 115-a can sample attitude 1 at 230. In some examples, attitude information 210 and control information 215 can be acquired (e.g., sampled) at a data rate of approximately 0.5-2 Mbps and can be transmitted to server 205 at approximately every 2 ms (e.g., 500 Hz). Alternatively, attitude information 210, control information 215, or both, can be sampled and / or transmitted in a file size of 1 Kbit (e.g., 125 bytes) or 4 Kbit (e.g., 500 bytes). In contrast, scene information can be acquired (e.g., sampled) at a data rate of approximately 10 Mbps and transmitted to server 205 at a rate of 10 Hz. In addition, scene information can be sampled and / or transmitted at a file size of 1 Mbit per 100ms (e.g., 125 Kbyte).

[0107] At 225, UE 115-a can transmit sampled information (transmission attitude 1 225) to server 205. In some aspects, UE 115-a can transmit the sampled information within the first uplink symbol after the time when the information (e.g., attitude information 210, control information 215, scene information) was sampled. At 230, the sampled information can be received at server 205. At 235, server 205 can render and encode new XR frames based on (e.g., according to) the received information (attitude 1). In some aspects, XR frames can be generated periodically and can be divided into multiple slices that are encoded separately. Figure 2 As shown, the age of the acquired information (e.g., pose age 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 on server 205.

[0108] At 245, XR frames can be transmitted to base station 105-a. In some aspects, each encoded slice of the XR frame (file) can be transmitted individually from server 205 to base station 105-a. At 250, base station 105-a can transmit the received XR frames to UE 115-a. In some aspects, slices of XR frames can be transmitted to UE 115-a via multiple TBs or TB bursts. For example, as will be discussed in this document... Figure 3As discussed in further detail, base station 105-a can transmit data to 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 base station 105-a to UE 115-a can be characterized by a downlink delay budget 260. At 265, UE 115-a can decode the data received from base station 105-a (e.g., decode XR frame burst 255) and perform an asynchronous time warping process. Subsequently, at 270, the received XR frame can be displayed at UE 115-a. Figure 2 Examples can depict the delay from motion to render to photon (e.g., motion-to-render-to-photon delay 275).

[0109] In some cases, the period at which UE 115-a transmits attitude information 210 and / or other control information may occur at a different period than that of the XR frame burst 255, resulting in wasted power consumption. For example, UE 115-a may transmit attitude information 210 to server 205 and / or base station 105-a according to a configured authorization. This configuration authorization can define a set of parameters (e.g., MCS, TBS, etc.) for UE 115-a to use in transmitting attitude information 210 and other control information to server 205 and / or base station 105-a. However, in some cases, channel conditions may vary between UE 115-a and server 205 and / or base station 105-a. Therefore, such retransmissions may add unnecessary latency to XR applications. UE 115-a may retransmit attitude information 210 and other control information multiple times because UE 115-a is configured to use the same set of parameters, and the channel conditions may not improve even if the set of parameters is sufficient for retransmission.

[0110] In the wireless communication system 200, UE 115-a can be configured with a configurable license carrying multiple sets of parameters. Thus, UE 115-a can be configured to select the parameter set based on channel conditions to achieve power-saving improvements. In other words, UE 115-a can adapt to changing channel conditions, which can improve reliability and reduce power consumption for XR applications. In some examples, UE 115 can dynamically indicate the selected set of parameters for semi-persistent uplink data transmission (also known as configurable licensed transmission). In other examples, UE 115 can directly indicate the parameter values ​​of the selected set of parameters. For example, UE 115 can transmit indications, MCS index values, TBS index values, antenna ports, PMI index values, layer numbers, etc., to base station 105 or server 205 or both.

[0111] UE 115 can transmit dynamic indications (e.g., Uplink Control Information (UCI)) via uplink control channels (such as PUCCH). PUCCH resources can be pre-allocated and associated with configured-grant resources. PUCCH resources can have the same or different periods as the associated configured-grant resources. Optionally, UE 115 can transmit dynamic indications via a MAC-CE message (also known as MAC-CE) over the current configured-grant transmission and apply from the next configured-grant transmission. For transmission over the current configured-grant transmission, MAC-CE can be multiplexed with the current uplink data. In some other examples, UE 115 can transmit dynamic indications via RRC messages to indicate its preferred set of parameters or values.

[0112] Server 205 (e.g., an XR server) can adaptively change its transmission rate (e.g., frames per second, frame quality / resolution) based on channel conditions, buffer status, or both. If base station 105 determines that the average channel conditions of UE 115 have deteriorated, base station 105 can provide feedback to server 205 to reduce its transmission rate. Base station 105 can use downlink buffer status, channel state feedback from UE 115, or measurement reports from UE 115 to identify whether the channel to UE 115 has deteriorated. If the XR application receive rate (e.g., frames per second, frame quality / resolution) of UE 115 is below a certain threshold, UE 115 can provide feedback to server 205 or base station 105, or both, to adjust its transmission rate.

[0113] Base station 105 can adjust its license configuration to accommodate adjusted rate changes in the application layer. Base station 105 can thus transmit DCI messages (in the downlink control channel (e.g., PDCCH)) or MAC-CE messages to UE 115 to update or reactivate parameters in the configured license configuration. UE 115 can update the period, repetition factor value, or the number of time slots allocated in the configured license, or any combination thereof, based on messages received from base station 105. UE 115 can transmit, and base station 105 can receive, a MAC-CE indicating the activation or deactivation of one or more configured licenses or a set of configured licenses, or both. The MAC-CE may include a sequence of bits, where each bit corresponds to a configured license or a set of configured licenses configured via RRC signaling. UE 115 can transmit the MAC-CE to base station 105 to indicate which configured license to activate or deactivate, or to switch to which set of configured licenses. In this way, UE 115 can dynamically transmit MAC-CE to base station 105 to update or reactivate one or more parameters associated with the configured authorization configuration. For example, one or more parameters may include one or more configured authorization offsets, periods, repetition factor values ​​(e.g., repK), the number of time slots allocated in the configured authorization period, and indications for activation and / or deactivation of one or more configured authorizations or a set of configured authorizations.

[0114] To conserve power, downlink reception and uplink transmission can be synchronized, allowing UE 115 to receive downlink frames and transmit uplink attitude information simultaneously or close in time. In some examples, if the number of frames generated per second from server 205 (encoder) is changed for adaptation, base station 105 can also change its physical layer parameters to adapt its resources to match the reduced frame rate. This adaptation can reduce radio resource waste and lower power consumption. The subsequent downlink and uplink resources and / or parameters at base station 105 can be related to the XR frame generation rate: discontinuous reception cycle, grant cycle, semi-persistent scheduling cycle, scheduling request cycle, or a combination thereof. Using downlink signaling, base station 105 can jointly indicate downlink and uplink resources and / or parameters to adapt to the new adjusted frame generation rate in the application layer. This list / set of parameters is pre-configured, and base station 105 can indicate which one to apply dynamically.

[0115] Figure 3 An example of an adaptive, configuration-authorized downlink and uplink configuration 300 for power saving, according to aspects of this disclosure, is shown. The downlink and uplink configurations 300 can be implemented separately according to reference. Figure 1 and Figure 2The aspects of the described wireless communication systems 100 and 200, or aspects of the wireless communication systems 100 and 200, can be implemented separately. The downlink and uplink configuration 300 can be configured based on base station 105 and implemented by UE 115. The downlink and uplink configuration 300 can configure time resources (e.g., symbols, micro-slots, time slots) and frequency resources (e.g., carriers, subcarriers). The downlink and uplink configuration 300 can support various 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.

[0116] Base station 105 can transmit one or more frame bursts 305, and UE 115 can receive one or more frame bursts 305, each carrying one or more frames associated with an application. For example, base station 105 can transmit one or more XR frame bursts, and UE 115 can receive one or more XR frame bursts carrying one or more XR frames associated with an XR application. Frames can be divided into individually coded slices. Base station 105 can transmit coded slices over the air via multiple TBs (TB bursts). In some examples, base station 105 can transmit frame bursts 305 according to a period 310 (e.g., a frame generation period), which can be based on the frame rate of an application such as an XR application (e.g., a frame rate of 60Hz or 120Hz, which provides frame generation periods of 16.67ms or 8.33ms, respectively). UE 115 can thus receive frame bursts 305 based on period 310. Figure 3 In the example, there may be one or more power-saving moments 315 between frame bursts 305, allowing UE 115 to experience additional power saving.

[0117] UE 115 may determine one or more power-saving opportunities 315 between frame bursts 305, at least in part, based on period 310. For example, UE 115 may determine power-saving opportunity 315-a between two consecutive frame bursts (e.g., frame burst 305-a and frame burst 305-b). Additionally or alternatively, UE 115 may determine 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, UE 115 may not experience the additional power saving associated with one or more power-saving opportunities 315 because the configured grant period may differ from the downlink traffic period (e.g., frame burst 305). In some other cases, UE 115 may not experience the additional power saving associated with one or more power-saving opportunities 315 because of uplink retransmissions due to changes in channel conditions (e.g., retransmissions of attitude information and / or control information), which result in wasted power consumption. Therefore, one or more power-saving opportunities 315 between frame bursts 305 are not used. To benefit from power saving time 315, UE 115 can be configured with a configuration grant that includes multiple sets of parameters, and UE 115 can select a set of parameters from the configuration grant based on channel conditions. Therefore, UE 115 can adapt to changing channel conditions, which can improve reliability and reduce power consumption for XR applications.

[0118] Figure 4A An example of an adaptive configuration-authorized transmission configuration 400-a for power saving, according to aspects of this disclosure, is shown. Transmission configuration 400-a can be implemented with reference to [reference to other documents]. Figure 1 and Figure 2 Aspects of the described wireless communication systems 100 and 200. For example, transmission configuration 400-a can be based on the configuration of base station 105 and implemented by UE 115. Figure 4A In the example, base station 105 can transmit authorization configuration, and UE 115 can receive authorization configuration. For example, base station 105 can transmit authorization configuration via an RRC procedure, and UE 115 can receive authorization configuration via an RRC procedure. Thus, base station 105 can transmit an RRC message carrying authorization configuration, and UE 115 can receive an RRC message carrying authorization configuration. The configured authorization may include a single set of parameters (e.g., MCS, TBS, etc.) for UE 115 to use for downlink reception and uplink transmission.

[0119] exist Figure 4AIn the example, once the configured authorization is activated by base station 105 (e.g., via DCI messages) or UE 115, or both, it remains unchanged until it is deactivated or reactivated. This static configured authorization may result in additional power consumption and other unnecessary resource usage for base station 105 or UE 115, or both. For example, in some cases, base station 105 or UE 115, or both, may determine changes in channel conditions (e.g., link quality) between base station 105 and UE 115, which could negatively affect downlink reception 405-a and uplink transmission 410-a of UE 115 (e.g., semi-static uplink transmission). As a result, UE 115 may have to retransmit uplink transmissions to base station 105. For example, UE 115 may use the same single set of parameters to retransmit uplink control or data. Therefore, uplink transmission 410-a is prolonged due to retransmission. In some cases, retransmission may be ineffective for base station 105 or UE 115, or both. For example, in XR applications, retransmissions can be detrimental and may negatively impact the user experience because uplink transmissions (e.g., carrying attitude and / or control information) must occur with relatively low latency in order to reduce power consumption (e.g., reducing power level 415-a).

[0120] Figure 4B An example of an adaptive configuration-authorized transmission configuration 400-b for power saving, according to aspects of this disclosure, is shown. Transmission configuration 400-b can be based on the configuration of base station 105 and implemented by UE 115 to facilitate power saving of UE 115 by selecting a set of channel condition parameters based on the channel conditions between base station 105 and UE 115. Transmission configuration 400-b can also be based on the configuration of base station 105 and implemented by UE 115 to facilitate high reliability and low latency semi-persistent uplink operation, among other benefits. Figure 4B In the example, base station 105 can transmit authorization configuration, and UE 115 can receive authorization configuration. For example, base station 105 can transmit authorization configuration via an RRC procedure, and UE 115 can receive authorization configuration via an RRC procedure. Thus, base station 105 can transmit an RRC message carrying authorization configuration, and UE 115 can receive an RRC message carrying authorization configuration. The configured authorization may include multiple sets of parameters (e.g., MCS, TBS, etc.) for UE 115 to use for downlink reception and uplink transmission.

[0121] Similar to Figure 4ABase station 105 or UE 115, or both, can determine changes in the link quality between base station 105 and UE 115, which may negatively affect UE 115's downlink reception 405-b and uplink transmission 410-b (e.g., semi-static uplink transmission). As a result, UE 115 may have to retransmit uplink transmission 410-b to base station 105. However, in Figure 4B In the example, UE 115 can select different sets of parameters from the configured authorization to adapt to changes in link quality between base station 105 and UE 115. For example, different sets of parameters can have different MCS values, TBS values, etc. UE 115 can thus use the selected set of parameters to retransmit uplink transmission 410-b to improve the reliability of retransmission, which results in lower latency retransmissions and reduced power consumption 415-b for UE 115.

[0122] Figure 5 An example of an adaptively configurable timeline 500 for power saving, supported by aspects of this disclosure, is shown. Timeline 500 can be implemented with reference to [reference needed]. Figure 1 and Figure 2 The described wireless communication systems 100 and 200 may be one or more aspects, or implemented by these aspects. Timeline 500 may be based on the configuration of base station 105 and implemented by UE 115 to facilitate power saving of UE 115 by selecting a set of parameters based on channel conditions between base station 105 and UE 115. Timeline 500 may also be based on the configuration of base station 105 and implemented by UE 115 to facilitate high reliability and low latency semi-persistent uplink operation, among other benefits.

[0123] Referring to timeline 500, the channel condition 505 between base station 105 and UE 115 can vary within time period 510. For example, channel condition 505 can correspond to a first channel quality level at a first time instance 515-a, a second channel quality level at a second time instance 515-a, and a third channel quality level at a third time instance 515-a. Because the channel condition 505 between base station 105 and UE 115 varies within time period 510, it may be beneficial for UE 115 to adapt to the changing channel condition 505 to maintain high reliability and low latency uplink operation. For example, UE 115 can select a first set of parameters for uplink transmission 520-a during the first time instance 515-a. The first set of parameters may include one or more parameters, each with a specific value when channel condition 505 corresponds to, for example, a specific channel link quality, path loss, etc. For example, the first parameter set may have a repetition factor value of 1, an MCS index value of 14, and a TBS index value of 200 (i.e., the first parameter set = {repK = 1, MCS = 14, TBS = 200}). Additionally or alternatively, UE 115 may use one or more other parameters as described herein.

[0124] During a second time instance 515-b or a third time instance 515-c, or both, UE 115 may select a second set of parameters for uplink transmission 520-b, uplink transmission 520-c, or both. The second set of parameters may include one or more parameters, each with a specific value when channel condition 505 corresponds to different channel link quality, path loss, etc. For example, the second set of parameters may have a repetition factor value of 2, an MCS index value of 10, and a TBS index value of 100 (i.e., second set of parameters = {repK = 2, MCS = 10, TBS = 100}). Additionally or alternatively, UE 115 may use one or more other parameters as described herein. In some examples, UE 115 may use the same set of parameters for uplink transmission 520-b and uplink transmission 520-c because channel condition 505 may be the same during the second time instance 515-b and the third time instance 515-c. Alternatively, UE 115 can use the same set of parameters for uplink transmission 520-b and uplink transmission 520-c, since channel condition 505 can be within a threshold (e.g., a degradation level threshold) between the second time instance 515-b and the third time instance 515-c.

[0125] UE 115 can transmit one or more uplink transmissions 520 to base station 105, and base station 105 can blindly detect the uplink transmissions 520. Base station 105 can blindly detect the uplink transmissions 520 based on possible parameter configurations. That is, considering the changing channel conditions 505, base station 105 can blindly detect the uplink transmissions 520 based on multiple sets of parameters configured by base station 105 for UE 115 to use for the uplink transmissions 520. Therefore, UE 115 can be configured with a configurable grant including multiple sets of parameters, and UE 115 can dynamically select the parameter sets from the configurable grant based on channel conditions 505. Therefore, UE 115 can adapt to changing channel conditions 505, which can result in reduced power consumption for UE 115.

[0126] Figure 6 An example of an adaptive configuration-authorized process flow 600 for power saving, according to aspects of this disclosure, is shown. Process flow 600 can be implemented with reference to the following references: Figure 1 and Figure 2 The described wireless communication system 100 and wireless communication system 200 may be implemented by or based on one or more aspects of these aspects. Process flow 600 may be based on the configuration of base station 105-b and implemented by UE 115-b to facilitate power saving of UE 115-b by selecting a set of channel condition parameters based on the channel conditions between base station 105-b and UE 115-b. Process flow 600 may also be based on the configuration of base station 105-b and implemented by UE 115-b to facilitate high reliability and low latency semi-persistent uplink operation (e.g., transmission of location information and control information of UE 115-b for XR applications), and other benefits. In the following description of process flow 600, operations between base station 105-b and UE 115-b may be transmitted in a different order than the example order shown, or operations performed by base station 105-b and UE 115-b may be performed in a different order or at different times. Some operations may also be omitted from process flow 600, and other operations may be added to process flow 600. Base station 105-b and UE 115-b can be referenced separately. Figure 1 and Figure 2 Examples of base station 105 and UE 115 are described.

[0127] At 605, base station 105-b can determine the authorized configuration of UE 115-b. This authorized configuration can include multiple sets of parameters. Each set of parameters can include one or more parameters for semi-persistent uplink data. For example, for XR applications, one or more parameters can include uplink parameters and downlink parameters associated with the semi-persistent uplink data. For example, base station 105-b can jointly transmit the uplink and downlink parameters associated with the semi-persistent uplink data via downlink signaling (e.g., RRC, MAC-CE, DCI) to adapt to the frame generation rate in the application layer associated with UE 115-b. Using downlink signaling, base station 105-b can jointly indicate downlink and uplink resources and / or parameters to adapt to a new, adjusted frame generation rate in the application layer. This list / set of parameters is pre-configured, and base station 105-b can indicate which one to apply dynamically.

[0128] In some examples, for instance, based on channel conditions, each parameter set may include different values ​​for one or more parameters. That is, when the channel conditions correspond to a certain channel condition (e.g., channel link quality, path loss, etc.), base station 105-b may assign parameter sets to include one or more parameters, each with a specific value. For example, base station 105-b may assign repetition factor values, MCS index values, TBS index values, number of layers, number of antenna ports, PMI index values, or any combination thereof based on specific channel conditions. Additionally or alternatively, downlink parameters or uplink parameters, or both, include discontinuous reception cycle periods, grant periods, semi-persistent scheduling periods, scheduling request periods, or combinations thereof. At 610, base station 105-b may transmit a configured grant including multiple parameter sets to UE 115-b via signaling. In some examples, the signaling may include MAC-CE messages, RRC messages, or DCI messages, or combinations thereof.

[0129] In 615, UE 115-b can select a parameter set from multiple parameter sets received, for example, from a configured grant from base station 105-b. For example, UE 115-b can receive the parameter set based on channel conditions between base station 105-b and UE 115-b. In some examples, UE 115-b can determine the channel conditions based on channel link quality measurements, path loss measurements, channel state information measurements, etc. Based on the determined channel conditions, UE 115-b selects from multiple sets that may be suitable for those channel conditions. For example, UE 115-b can select a parameter set including one or more parameters (e.g., repetition factor, MCS index, TBS index, PMI index, etc.), each parameter having a specific value suitable for the channel conditions (e.g., repetition factor value, MCS index value, TBS index value, precoding matrix index value, etc.). UE 115-b can thus dynamically select a parameter set from multiple parameter sets related to link adaptation for configured grant transmissions (e.g., semi-persistent uplink data transmissions).

[0130] At 620, UE 115-b may optionally transmit an indication of a selected set of parameters to base station 105-b. In some examples, UE 115-b may transmit an indication of one or more parameters associated with the selected set of parameters in a MAC-CE message. In some examples, UE 115-b may multiplex the MAC-CE message with another uplink transmission to base station 105-b. In some other examples, UE 115-b may transmit an indication of one or more parameters associated with the selected set of parameters in an RRC message. This indication may identify one or more parameter values ​​of one or more parameters associated with the selected set of parameters for configured licensed transmissions (e.g., semi-persistent uplink data transmissions). For example, UE 115-b may use one or more uplink resources to transmit an indication of one or more parameters associated with the selected set of parameters on an uplink channel (e.g., PUCCH). The one or more uplink resources may include one or more pre-configured PUCCH resources associated with one or more licensed resources, which are associated with configured licenses. The one or more PUCCH resources and the one or more licensed resources may have the same period. Alternatively, one or more PUCCH resources and one or more licensed resources may have different periods. At 625, UE 115-b can determine the semi-persistent uplink data to be transmitted to base station 105-b. For example, as described herein, UE 115-b may generate attitude information or control information, or both, for XR applications. At 630, UE 115-b may transmit semi-persistent uplink data (e.g., configured licensed transmission) to base station 105-b using a selected set of parameters.

[0131] Figure 7 A block diagram 700 of an adaptive configuration-authorized device 705 supporting power saving according to aspects of this disclosure is shown. Device 705 may be an example of an aspect of UE 115 as described herein. Device 705 may include a receiver 710, a UE communication manager 715, and a transmitter 720. Device 705 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0132] Receiver 710 can receive information associated with various information channels (e.g., control channels, data channels, and information related to adaptive configuration authorization for power saving), such as packets, user data, or control information. This information can be transmitted to other components of device 705. Receiver 710 can serve as a reference. Figure 10 Examples of aspects of the transceiver 1020 described. The receiver 710 may utilize a single antenna or an array of antennas.

[0133] The UE communication manager 715 can be implemented as an integrated circuit or chipset of device 705, while the receiver 710 and transmitter 720 can be implemented as analog components (e.g., amplifiers, filters, antennas) coupled to the modem of device 705 to enable wireless transmission and reception. Actions performed by the UE communication manager 715 as described herein can be implemented to achieve one or more potential advantages. The UE communication manager 715 can be an example of an aspect of the UE communication manager 1010 as described herein. By including or configuring the UE communication manager 715 according to the examples described herein, device 705 (e.g., a processor that controls or otherwise couples to receiver 710, transmitter 720, UE communication manager 715, or combinations thereof) can support a configurable authorization including multiple sets of parameters, and the UE communication manager 715 can select a set of parameters from the configurable authorization based on channel conditions (e.g., channel link quality measurements, path loss measurements, channel state information measurements).

[0134] For example, the UE communication manager 715 can receive an authorized configuration including multiple sets of parameters, each set including one or more parameters for semi-persistent uplink data. The UE communication manager 715 can select a set of parameters from these multiple sets based on channel conditions, and transmit the semi-persistent uplink data to the base station using the selected set of parameters. Based on the adapted configuration authorization, one or more processors of device 705 (e.g., processor(s) controlling or combined with the UE communication manager 715) can facilitate improved power consumption, and in some examples, can facilitate enhanced efficiency for high-reliability and low-latency wireless communication operation, among other benefits.

[0135] The UE communication manager 715 or its sub-components may be implemented in hardware, processor-executable code (e.g., software or firmware), or any combination thereof. If implemented in processor-executable code, the functionality of the UE communication manager 715 or its sub-components may be performed 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 this disclosure.

[0136] The UE communication manager 715 or its sub-components may be physically located in various locations, including distributed systems, such that some functions are implemented by one or more physical components in different physical locations. In some examples, according to various aspects of this disclosure, the UE communication manager 715 or its sub-components may be separate and distinct components. In some examples, according to various aspects of this disclosure, the UE communication manager 715 or its sub-components may be combined with one or more other hardware components, including but not limited to input / output (I / O) components, transceivers, network servers, another computing device, one or more other components described in this disclosure, or combinations thereof.

[0137] Transmitter 720 can transmit signals generated by other components of device 705. In some examples, transmitter 720 can be co-located with receiver 710 in a transceiver assembly. For example, transmitter 720 can be a reference. Figure 10 Examples of aspects of the transceiver 1020 described. The transmitter 720 may utilize a single antenna or an array of antennas.

[0138] Figure 8 A block diagram 800 of an adaptively configured device 805 supporting power saving according to aspects of this disclosure is shown. Device 805 may be an example of a device 705 as described herein or an aspect of UE 115. Device 805 may include a receiver 810, a UE communication manager 815, and a transmitter 835. Device 805 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0139] Receiver 810 can receive information associated with various information channels (e.g., control channels, data channels, and information related to adaptive configuration authorization for power saving), such as packets, user data, or control information. This information can be transmitted to other components of device 805. Receiver 810 can serve as a reference. Figure 10 Examples of aspects of the transceiver 1020 described.
