[0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 63 / 044,936, filed June 26, 2020, entitled “BANDWIDTHPART CONFIGURATION TECHNIQUES FOR WIRELESS COMMUNICATIONS SYSTEMS”, which has been assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] In summary, the following text relates to wireless communication, and more specifically, to bandwidth configuration techniques for wireless communication systems. 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 can 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), Improved LTE (LTE-A), or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies 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).

[0005] A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication with multiple communication devices (which may also be referred to as user equipment (UE)). The UE and the base station can transmit data in the wireless communication system. For example, the base station can configure the UE with a bandwidth portion for uplink or downlink communication. However, conventional methods for configuring the bandwidth portion may result in relatively inefficient communication, high power consumption at the UE, or both. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses that support bandwidth part configuration techniques for wireless communications systems. Generally, the described techniques enable devices (e.g., base stations or user equipment (UEs)) of a wireless communications system to determine a bandwidth size of a bandwidth part based on one or more parameters. For example, a base station can configure a UE (e.g., via control signaling) with a bandwidth part for communications of application data traffic. The base station can select a bandwidth part from a set of bandwidth parts based on the bandwidth part having a bandwidth size (e.g., a frequency range) that corresponds to a traffic burst size (e.g., an estimated traffic burst size) for application data traffic. In some examples, the base station can determine a bandwidth size and configure the UE with a bandwidth part that satisfies the determined bandwidth size. In some other examples, the UE can determine a bandwidth size and indicate a requested bandwidth size to the base station, which can enable the base station to configure a bandwidth part in accordance with the indicated bandwidth size.

[0007] As an illustrative example, a device can determine a bandwidth size that is capable of carrying a burst of application data within a time period (e.g., a slot). In some examples, the device can estimate a transport block size for a burst of application data traffic (e.g., an estimated traffic burst size can be an example of an estimated transport block size) based on a quality of service (QoS) profile, an average transport block size for previous communications, or both, among other examples. The device can determine the bandwidth size based on one or more parameters. For example, the device can determine the bandwidth size based on a transport block size, a modulation order, a target code rate, a number of layers, a number of downlink symbols for scheduling communications, a physical layer overhead parameter, a statistical metric (e.g., an average, a standard deviation, a maximum value, and the like) of one or more parameters, or any combination thereof.

[0054] A base station and a user equipment (UE) can communicate in a wireless communication system. For example, a base station can schedule a UE for one or more data transmissions (e.g., uplink or downlink transmissions of application data traffic for an application of the UE). The base station can configure the UE with a bandwidth part for such communications. However, in some cases, configuring a bandwidth part can result in relatively inefficient communications, high power consumption at the UE, or both. For example, a UE can be configured with a bandwidth part having a bandwidth size that spans an entire carrier bandwidth, which can result in relatively inefficient power usage at the UE (e.g., if the UE is capable of using less bandwidth while maintaining latency and throughput thresholds for the application data traffic, e.g., for split cross reality (XR) applications having relatively predictable throughput and periodicity, etc.).

[0055] According to the techniques described herein, a device (e.g., a base station or a UE) of a wireless communication system can determine a bandwidth size for a bandwidth part based on one or more parameters, such as a traffic burst size (e.g., an estimated traffic burst size). For example, a base station can configure a UE (e.g., via control signaling) with a bandwidth part for communications of application data traffic. The base station can select a bandwidth part from a set of bandwidth parts based on the selected bandwidth part having a bandwidth size (e.g., a frequency range) that corresponds to a traffic burst size of the application data traffic (e.g., an estimated traffic burst size for the application data traffic) and other parameter examples. As an illustrative example, a device can use an estimated application burst size to determine a bandwidth size that can carry an application data burst in a time period (e.g., a bandwidth size that is large enough to transmit the estimated application data burst in a time slot and other examples of time periods). In some examples, the determined bandwidth size can be relatively smaller than an entire bandwidth size available for a carrier. In such examples, the UE can achieve enhanced power savings, and other advantages (e.g., due to the UE communicating over a bandwidth size that is smaller than a carrier bandwidth). In some other examples, the bandwidth size can span a carrier bandwidth (e.g., if the estimated application data burst is large enough to use multiple time periods, such as time slots, in order to successfully communicate data over the bandwidth part), which can ensure throughput and latency thresholds, and other advantages.

[0056] A device can estimate a transport block size of a burst of application data traffic (e.g., a traffic burst size can be an example of an estimated transport block size) based on a quality of service (QoS) profile, an average transport block size for previously scheduled communications, or both, among other examples. In some examples, a device can determine a bandwidth size based on one or more parameters such as a transport block size, a modulation order, a target code rate, a number of layers, a number of downlink symbols used to schedule a communication, a physical layer overhead parameter, a statistical measure (e.g., an average, a standard deviation, a maximum value, and the like) of one or more parameters (or any combination thereof), among other examples of parameters. In some examples, a base station can allocate a bandwidth part with a second bandwidth size that is higher than the determined bandwidth size, for example, to accommodate traffic fluctuations (e.g., temporal fluctuations due to a modulation order used for scheduling, a burst size generated by a server, and the like). In some examples, a base station can determine a size and configure a bandwidth part according to the determined size. In some other examples, a UE can determine a size and indicate the size to a base station, which can enable the base station to configure a bandwidth part according to the determined size.

[0057] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are then described in the context of resource schemes and process flows. Aspects of the disclosure are further illustrated by and described in conjunction with apparatus diagrams, system diagrams, and flowcharts that relate to bandwidth part configuration techniques for a wireless communication system.

[0058] Figure 1 An example of a wireless communication system 100 is shown in accordance with aspects of the present disclosure. The wireless communication 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 communication system 100 can be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication 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.

[0059] The base stations 105 can be dispersed throughout the geographic region 100 and can be geographic ly distributed in accordance with a particular arrangement or pattern. Some of the base stations 105, like the base stations 105a and 105b, can be macro cells (high-power cellular access points) for a terrestrial mobile network 100, while others, like the base stations 105c and 105d, can be small cells (low-power cellular access points) for a terrestrial mobile network 100. The base stations 105 can provide communication coverage for various techniques, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), time division synchronous code division multiple access (TD-SCDMA), or other protocols that can be employed.

[0060] 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 at different times. The UEs 115 can be devices in different forms or having different capabilities. 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 Figure 1 The base stations 105 can wirelessly communicate with the UEs 115 via one or more base station antennas under the control of the base station controllers 310 and / or other components of the base stations 105. Each base station 105 can provide communication coverage for a respective geographic area 110 via wireless communication signals. Each base station 105 can engage in wireless communications with multiple UEs 115 via one or more base station antennas under the control of the base station controller 310 and / or other components of the base station 105. The base stations 105 can communicate directly with one another through backhaul links 120 for the purposes of

[0061] The base stations 105 can be dispersed throughout the geographic region 100 and can be geographic ly distributed in accordance with a particular arrangement or pattern. Some of the base stations 105, like the base stations 105a and 105b, can be macro cells (high-power cellular access points) for a terrestrial mobile network 100, while others, like the base stations 105c and 105d, can be small cells (low-power cellular access points) for a terrestrial mobile network 100. The base stations 105 can provide communication coverage for various techniques, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), time division synchronous code division multiple access (TD-SCDMA), or other protocols that can be employed.

[0062] One or more of the base stations 105 described herein can include or can be referred to as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which can be referred to as a gNB), a Home NodeB, a Home eNodeB, or some other suitable terminology.

[0063] ​A UE 115 can include or can be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, 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. A UE 115 can also include or can be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. 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, and other examples.

[0064] The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115 that can sometimes act as relays or Figure 1 as shown in FIG. 1.

[0065] 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 having a defined physical layer structure for supporting communication links 125. For example, a carrier used for a communication link 125 can include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP) that is operated in accordance with one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operations for the carrier, user data, or other signaling. A wireless communication system 100 can support communication with a UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, a UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.

[0066] In some examples (e.g., in carrier aggregation configurations), a carrier can also have acquisition signaling or control signaling that coordinates operations for 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 placed according to a channel raster for discovery by UEs 115. Carriers can operate in a standalone mode, where initial acquisition and connection are via the carrier, or can operate in non-standalone mode, where connection is anchored through a different carrier (e.g., of the same or a different radio access technology).

[0067] Carriers 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 wireless communications 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 wireless communications system 100 (e.g., base stations 105, 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, wireless communications 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 for operating over portions (e.g., sub-bands, BWPs) or all of a carrier bandwidth.

[0068] Signal waveforms transmitted over carriers can be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In OFDM, for example, a resource element can consist of one symbol period (e.g., the 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, the coding rate of the modulation, or both). Thus, 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 can be. 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.

[0069] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. In some examples, 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 communication for UE 115 can be restricted to one or more active BWPs.

[0070] It can be expressed in a basic unit of time (which can be, for example, T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized according to radio frames, each having 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 be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into several time slots. Alternatively, 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 several symbol periods (e.g., this depends on the length of the cyclic prefix added before 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. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0072] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0073] 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. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the 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 group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner with one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having 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 specific UE 115.

[0074] In some examples, base station 105 may be mobile, and therefore provide 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.

[0075] 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 service prioritization, 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 are used interchangeably herein.

[0076] 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.

[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 to and from at least one user equipment (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 a network operator IP services 150. The operator IP services 150 can include the Internet, an 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, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, 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 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

[0081] The 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. The antennas of a base station 105 or a UE 115 can be co-located within one or more antenna assemblies, which can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays can be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a base station 105 can be located in different geographic locations. A base station 105 can have antenna arrays with a number of rows and columns of antenna ports that the base station 105 can use to support beamforming of communications to 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 for signals transmitted via antenna ports.

[0082] 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 and / or steer the shape of a signal in

[0083] The 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 reassembly 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 retransmissions at the MAC layer 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, to support radio bearers for the user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0084] In some examples, the wireless communications system can support split XR communications (e.g., split XR application data traffic communicated between a UE 115 and a base station 105). For example, split XR traffic can be an example of downlink communications (e.g., from a server to a device such as a UE 115) that includes two video streams (e.g., a video stream for each eye of an XR headset device, etc.). In some cases, the data traffic in each video stream can be generated periodically by a split XR application server. The data traffic can have a period that corresponds to the inverse of a video frame rate (e.g., the inverse of frames per second (fps)). As an illustrative example, a fps of 90 (e.g., 90 Hz) can take the inverse to yield a period of 11.12 ms, although any amount can be used.

[0085] In some cases, each video frame of a video stream can be transmitted in its entirety (e.g., a server can transmit an entire video frame) within a short duration (e.g., 2 ms or any other amount of time) after it is generated, which can enable real-time XR application data. Such transmissions can result in relatively well-defined boundaries between successive transmissions. As an illustrative example, traffic for a split XR application can be transmitted by a server (e.g., via a base station 105) in bursts. Each data burst can correspond to bits associated with two rendered video frames (e.g., each data burst can include bits for a video frame for a left eye and a video frame for a right eye) that are transmitted within a relatively short duration (e.g., 2 ms) with an inter-arrival time (e.g., a time between arrival of a first data burst and a second data burst, e.g., approximately l / fps duration). In some examples, burst sizes of application data described herein can vary according to one or more factors (e.g., based on content of frames, a ratio between intra-coded image frames and predicted image frames, etc.). In some examples, a throughput or periodicity of split XR communications can be relatively predictable (e.g., latency and throughput of application data traffic can remain relatively constant over a period of time).

[0086] In some cases, a base station 105 can schedule a UE 115 for one or more data transmissions (e.g., uplink or downlink transmissions of application data traffic for an application of the UE 115). The base station 105 can configure the UE 115 with a bandwidth part for such communications. However, in some cases, configuring a bandwidth part can result in relatively inefficient communications, high power consumption at the UE 115, or both. For example, a UE 115 can be configured with a bandwidth part having a bandwidth size that spans an entire carrier bandwidth (e.g., a 100 MHz bandwidth size, etc.), which can result in relatively inefficient power usage at the UE 115 (e.g., if the UE 115 is capable of using less bandwidth while meeting latency and throughput conditions for application data traffic, e.g., for a split XR application having a relatively predictable throughput and periodicity, etc.). Allocating less than the entire carrier bandwidth can reduce UE modem power consumption, e.g., during a split XR session.

[0087] Devices of the wireless communications system 100 (e.g., base stations 105 or UEs 115) can determine a bandwidth size of a bandwidth part based on one or more parameters, such as an estimated traffic burst size (e.g., an estimated traffic burst size of XR application data traffic and other examples of traffic and communications). For example, a base station 105 can configure a UE 115 (e.g., via control signaling) with a bandwidth part for communications of application data traffic. The base station can select the bandwidth part from a set of bandwidth parts based on the bandwidth part having a bandwidth size (e.g., a frequency range) that corresponds to a traffic burst size (e.g., an estimated traffic burst size) for the application data traffic and other examples of parameters. As an illustrative example, a device can use an estimated application burst size to determine a bandwidth size that is capable of carrying an application data burst in a time period (e.g., a bandwidth size that is large enough to transmit the estimated application data burst in a time slot and other examples of time periods). In some examples, the determined bandwidth size can be relatively smaller than a carrier bandwidth size. In such examples, the UE 115 can achieve enhanced power savings, among other advantages (e.g., due to the UE 115 communicating over a bandwidth size that is smaller than a carrier bandwidth). In some other examples, the bandwidth size can span the carrier bandwidth (e.g., if the estimated application data burst is large enough to use multiple time periods, such as time slots, to successfully transfer data over the bandwidth part), which can ensure throughput and latency thresholds, among other advantages.

[0088] Figure 2 An example of a wireless communications system 200 is shown in accordance with aspects of the present disclosure. In some examples, the wireless communications system 200 can implement aspects of the wireless communications system 100. For example, the wireless communications system 200 can include a UE 115-a and a base station 105-a, which can be examples of the corresponding devices described with reference to Figure 1 FIG. 1.

[0089] The wireless communications system 200 can support communications 205 between the base station 105-a and the UE 115-a within the coverage area 110-a. The communications 205 can include uplink or downlink data transmissions (e.g., application data traffic between the UE 115-a and the base station 105-a). In some examples, the communications 205 can be examples of split XR application data traffic as described with reference to Figure 1 FIG. 1, but it is to be understood that the communications 205 can be examples of any type of communications. For example, the data traffic (e.g., application data traffic) as described herein can include or be examples of data, control information, or combinations thereof, among other examples of data, information, or communications. The base station 105-a can schedule the UE 115-a for the communications 205.

[0090] The base station 105-a can configure the UE 115-a with a bandwidth part for transmitting or receiving data traffic. According to the techniques described herein, a device (e.g., the base station 105-a or the UE 115-a) can determine a bandwidth size of a bandwidth part based on an estimated size of a data traffic burst (e.g., a burst of split XR application data traffic and other examples of data traffic), in addition to or in place of one or more other parameters. In some examples, the UE 115-a can determine the bandwidth size and indicate the bandwidth size to the base station 105-a. Additionally or alternatively, the base station 105-a can determine the bandwidth size and configure the UE 115-a with a bandwidth part according to the bandwidth size.

[0091] The base station 105-a can transmit control signaling to the UE 115-a indicating a bandwidth part for communications. The control signaling can include RRC signaling, a downlink control message (e.g., downlink control information (DCI) on a PDCCH), or a combination thereof. The base station 105-a can select a bandwidth part from a set of bandwidth parts based on a size of the selected bandwidth part (e.g., the selected bandwidth part can have a size corresponding to a calculated bandwidth size for communicating an application traffic burst). As an illustrative example, the base station 105-a can configure the UE 115-a with a bandwidth part having a bandwidth size such that an application traffic burst can be scheduled to the UE 115-a in a time period (e.g., an estimated application traffic burst can be scheduled in one downlink slot). In some examples, scheduling application traffic in a time period (e.g., in one slot) can enhance (e.g., minimize) latency, improve power saving at the UE 115-a (e.g., due to a reduced number of slots for decoding a physical downlink shared channel (PDSCH) message conveying application data traffic), or both, among other advantages.

[0092] The base station 105-a can estimate a bandwidth size associated with an application traffic burst. For example, the base station 105-a can calculate one or more statistical measures, such as a mean value of the bandwidth (e.g., n prb ), to allow an estimated application traffic burst to be scheduled in one downlink slot. In other words, a bandwidth size can be calculated using a traffic burst size (e.g., an estimated traffic burst size), which can be an estimated transport block size for a burst of application traffic.

[0093] In some examples, the base station 105-a can determine the estimated traffic burst size based on the received indication. For example, the AMF can signal the QoS profile for the application data traffic to the base station 105-a. The base station 105-a can identify the estimated traffic burst size as a transport block size indicated by a parameter of the QoS profile (e.g., a default maximum burst size parameter can indicate an average transport block size corresponding to the application data traffic bursts). In some examples, the base station 105-a can convert a value of the indicated parameter (e.g., the default maximum burst size) to a transport block size based on a header size of one or more protocol layers (e.g., a header size of a user datagram protocol (UDP) layer, an internet protocol (IP), a PDCP layer, an RLC protocol layer, a MAC protocol layer, or a combination thereof can be considered to convert the value to a transport block size). Additionally or alternatively, the base station 105-a can determine the estimated traffic burst size by tracking transport block sizes scheduled to the UE 115-a over a time duration. For example, the base station 105-a can determine an average transport block size scheduled for previous application data traffic over one or more subsequent time periods. The base station 105-a can use the average transport block size as the estimated traffic burst size.

[0094] In some examples, one or more devices (e.g., the base station 105-a, the UE 115-a, or a combination thereof) can estimate the traffic burst size based on a number of bits, a time duration, a sum of sizes of one or more transport blocks, or any combination thereof. For example, a device can determine the estimated traffic burst size as a number of bits received at the device (e.g., the UE 115-a or the base station 105-a) over a time duration (such as a threshold time duration (e.g., a threshold time duration indicated to the device via control signaling or other signaling, a threshold time duration preconfigured at the device, or a combination thereof)). Additionally or alternatively, a device can determine the estimated traffic burst size based on a sum of transport block sizes scheduled over a time duration. For example, the base station 105-a can estimate the traffic burst size as a sum of transport block sizes scheduled to the UE 115-a over a time duration.

[0095] The base station 105-a (or the UE 115-a) can determine the bandwidth size according to one or more parameters. In some examples, the base station 105-a can estimate the bandwidth size based on a transport block size. For example, the base station 105-a can calculate the bandwidth size using an average transport block size corresponding to the application traffic bursts (e.g., n prb Additionally or alternatively, the base station 105-a can estimate the bandwidth size based on a modulation order of the application data traffic. For example, the base station 105-a can calculate the bandwidth size using an average modulation order corresponding to the scheduled application traffic (e.g., Q m Additionally or alternatively, the base station 105-a can estimate the bandwidth size based on a modulation order of the application data traffic. For example, the base station 105-a can calculate the bandwidth size using an average modulation order corresponding to the scheduled application traffic (e.g., Qprb ).

[0096] Additionally or alternatively, the base station 105-a can estimate the bandwidth size based on a target code rate of the application data traffic (e.g., an average target code rate, which can be denoted as “R”), a number of one or more spatial layers over which the application data traffic is transmitted or scheduled (e.g., an average number of layers, which can be denoted as “v”), a number of one or more symbols used to schedule the application data traffic (e.g., an average number of downlink symbols, which can be denoted as “N symb,sh ”), a physical layer overhead associated with scheduling the application data traffic (e.g., a number of physical layer overhead, which can be denoted as “N oh,PRB ”), or any combination thereof. Thus, in addition to or in lieu of other parameters as described herein, and other examples of parameters, the base station 105-a can use the transport block size to calculate an average bandwidth size (e.g., n prb ).

[0097] In some examples, the base station 105-a (or the UE 115-a) can determine the bandwidth size using one or more statistical measures of one or more parameters. For example, the base station 105-a can use an average value of one or more parameters (e.g., an average target coding rate, an average modulation order, etc.) over a time duration to calculate an average bandwidth size. Additionally or alternatively, the base station 105-a can use a maximum value of one or more parameters, an average value of one or more parameters plus one or more standard deviations, or any combination thereof, and other examples of statistical measures.

[0098] In some examples, the determined bandwidth size can satisfy a threshold for scheduling the application data traffic in a time period (e.g., a time slot) (e.g., the calculated bandwidth size can be less than a carrier bandwidth size), which can improve power consumption at the UE 115-a while ensuring that latency and throughput thresholds are met. For example, the UE 115-a can configure its radio frequency circuitry to monitor a bandwidth part of a bandwidth size that is less than the entire carrier frequency, which can save power during the time period.

[0099] In some other examples, the determined bandwidth size can fail to satisfy a threshold for scheduling application data traffic within a time period (e.g., a slot) (e.g., the computed bandwidth size can be greater than or equal to the carrier bandwidth size). For example, UE 115-a and base station 105-a can experience relatively poor channel conditions, and using a reduced bandwidth size for the bandwidth part can result in relatively inefficient communications (e.g., UE 115-a can fail to successfully receive or decode communication 205). In such examples, base station 105-a can allocate the entire carrier bandwidth (e.g., the selected bandwidth part can span the carrier bandwidth), base station 105-a can schedule the application data burst within multiple time periods (e.g., multiple slots), or a combination thereof, which can result in relatively high reliability communications, among other advantages.

[0100] In some examples, base station 105-a can allocate a bandwidth part having a second bandwidth size that is higher than the determined bandwidth size (e.g., base station 105-a can select and configure a bandwidth part having a second bandwidth size). By allocating a bandwidth part having a second bandwidth size, base station 105-a can accommodate traffic fluctuations (e.g., temporal fluctuations due to modulation order used for scheduling, burst sizes generated by servers, etc.), among other examples, which can result in improved communication efficiency and reliability.

[0101] According to the techniques described herein, base station 105-a and UE 115-a can communicate application data traffic using a configured bandwidth part having a bandwidth size. For example, base station 105-a can use a bandwidth part (e.g., a bandwidth part having a size equal to an estimated bandwidth size computed using one or more parameters or a second size that is greater than the estimated bandwidth size) to transmit an application data traffic burst to UE 115-a within one or more slots.

[0102] In some examples, base station 105-a or UE 115-a can establish a communication session (e.g., an XR session between an XR application data server and UE 115-a). For example, base station 105-a can establish a communication session with a UE using a first bit rate for communicating application data traffic (e.g., a video bit rate for XR data). In some examples, the communication session can be adjusted. For example, base station 105-a can adjust the communication session (or establish a second communication session) to use a second bit rate for application data traffic. In such examples, base station 105-a can configure different bandwidth part sizes corresponding to different bit rates. For example, base station 105-a can configure a first bandwidth part having a first size for a first communication session, and base station 105-a can configure (e.g., via a second control signal) a second bandwidth part having a second size different from the first size for an adjusted communication session (or a second communication session), in accordance with the techniques described herein. For example, a bandwidth size of a wide bandwidth part configured for a first bit rate can be different compared to a bandwidth size of a bandwidth part configured for a second bit rate.

[0103] Figure 3 An example of a resource scheme 300 is shown in accordance with aspects of the disclosure. In some examples, resource scheme 300 can implement aspects of wireless communication system 100 or wireless communication system 200. For example, resource scheme 300 can illustrate example communications between a UE 115 and a base station 105 (which can be examples of the corresponding devices described herein with reference to Figure 1 and 2 described herein.

[0104] A base station can schedule communications with a UE on a set of resources, such as the time-frequency resources shown in resource scheme 300. A base station can configure a bandwidth part 310 within a carrier bandwidth 305, as described herein. A UE or base station can determine an estimated size 320 of the bandwidth part 310 based on one or more parameters as described herein with reference to Figure 2 For example, a UE or base station can determine an estimated size 320 of the bandwidth part 310 using an estimated size of a burst of application data traffic 325 (e.g., based on a statistical measure of one or more parameters as described herein). A base station can select and indicate a bandwidth part 310 having an estimated size 320 or a second size that is greater than the estimated size 320 (e.g., to account for traffic variations). In some examples, the estimated size 320 can be referred to as a burst size (e.g., a traffic burst size for application data traffic over a time period such as a slot 315-a) or an estimated burst size (e.g., an estimated traffic burst size for application data traffic over a time period such as a slot 315-a). That is,Figure 3 An example of selecting a burst size (e.g., an estimated burst size 320) for the bandwidth part 310 can be shown.

[0105] In some examples, the bandwidth part 310 can have a size that is less than the carrier bandwidth 305, e.g., if a burst of application data traffic 325 (e.g., an estimated transport block size for an instance of application data traffic) can be scheduled within the slot 315-a. In such examples, the UE and the base station can achieve improved power consumption while ensuring that latency and throughput thresholds of the application data traffic 325 are met. For example, the UE can save power by tuning its analog circuitry to a smaller bandwidth than the entire bandwidth of the carrier.

[0106] In some other examples, the bandwidth part 310 can have a size that is equal to the carrier bandwidth 305, e.g., if a burst of application data traffic 325 is estimated to use multiple slots (e.g., if the estimated application traffic burst size is large enough, channel conditions are relatively poor, or both) in order to ensure successful communication (e.g., a higher reliability communication that meets latency or throughput thresholds of the application data traffic 325) and other benefits. In other words, the estimated traffic burst size for the application data traffic 325 can be larger than an allowed burst size for a maximum bandwidth size of a single slot 315-a. For example, based on the estimated traffic burst size being larger than an allowed burst size for a maximum bandwidth size of a single slot 315-a, the application data traffic 325 can be communicated within the slot 315-a and the slot 315-b on the bandwidth part 310 allocated to span the carrier bandwidth 305, but any number of slots 315 or bandwidth sizes can be used.

[0107] Figure 4 An example of a process flow 400 in accordance with aspects of the present disclosure is shown. In some examples, the process flow 400 can implement aspects of the wireless communication system 100 or the wireless communication system 200. For example, the process flow 400 can illustrate operations and communications of a base station 105-b and a UE 115-b (which can be examples of the corresponding devices described herein with reference to Figures 1-3 The UE 115-b and the base station 105-b can communicate using a bandwidth part having a bandwidth size determined according to one or more parameters, as described herein with reference to Figures 1-3

[0108] In some examples, at 405, the UE 115-b can determine a bandwidth part size. For example, the UE 115-b can calculate a first bandwidth part size using one or more parameters, as described herein with reference to Figure 2 ​The first bandwidth size can be smaller than the configured carrier bandwidth (e.g., if the estimated application data burst can be scheduled within a desired time period, such as a slot) or the first bandwidth size can be the same as the configured carrier width (e.g., if the estimated application data burst can be scheduled within a set of slots to ensure relatively reliable communication). In some examples, the determined bandwidth part size can be the computed first bandwidth size. In some other examples, the determined bandwidth size can be a second bandwidth size that is larger than the computed first bandwidth size (e.g., to accommodate traffic fluctuations of the application data traffic).

[0109] In some examples, at 410, UE 115-b can transmit a size indication to base station 105-b. For example, if UE 115-b is configured to determine a bandwidth part size, UE 115-b can use uplink control signaling to indicate the bandwidth part size determined at 405. Additionally or alternatively, UE 115-b can transmit a capability message to base station 105-b (e.g., as part of a connection setup procedure) prior to the operations shown at 405 and 410.

[0110] At 415, base station 105-b can determine a bandwidth part size. For example, base station 105-b can use the indicated bandwidth part size received at 410 to determine a bandwidth part size. In some other examples, the bandwidth part size can be determined at base station 105-b without receiving an indication. For example, base station 105-b can use one or more parameters (e.g., application traffic burst size, modulation order, target coding rate, etc.) to compute a first bandwidth part size as described herein with reference to Figure 2 The first bandwidth size can be smaller than the configured carrier bandwidth (e.g., if the estimated application data burst can be scheduled within a desired time period, such as a slot) or the first bandwidth size can be the same as the configured carrier width (e.g., if the estimated application data burst can be scheduled within a set of slots to ensure relatively reliable communication). In some examples, the determined bandwidth part size can be the computed first bandwidth size. In some other examples, the determined bandwidth size can be a second bandwidth size that is larger than the computed first bandwidth size (e.g., to accommodate traffic fluctuations of the application data traffic).

[0111] At 420, base station 105-b can transmit control signaling to UE 115-b. For example, base station 105-b can configure UE 115-b to communicate using a bandwidth part having a bandwidth size determined using the control signaling (e.g., RRC signaling, DCI, and other examples of control signaling). In some examples, base station 105-b can select a bandwidth part having a bandwidth size from a set of bandwidth parts.

[0112] At 425, UE 115-b and base station 105-b can communicate using the configured bandwidth part. For example, base station 105-b can communicate application data traffic with UE 115-b on the bandwidth part. In some examples, base station 105-b can schedule the communication at 425 (e.g., via control signaling such as DCI messages) in accordance with aspects described herein.
