TECHNICAL FIELD
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Patent Application No. 17 / 651,366 filed on February 16, 2022, entitled "FREQUENCY HOPPING ENABLING FOR AN UPLINK CONTROL CHANNEL TRANSMISSION BY A USER EQUIPMENT", and the benefit of U.S. Provisional Patent Application No. 63 / 260,038 filed on August 6, 2021, entitled "FREQUENCY HOPPING ENABLING FOR AN UPLINK CONTROL CHANNEL TRANSMISSION BY A USER EQUIPMENT", all of these patent applications are expressly incorporated herein by reference in their entirety.
[0002] Aspects of the present disclosure generally relate to wireless communication systems, and more specifically to communication systems that use frequency hopping for wireless transmission.
BACKGROUND ART
[0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcasting, etc. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing available network resources. Such networks may be multiple-access networks that support communications for multiple users by sharing available network resources.
[0004] A wireless communication network may include several components. These components may include wireless communication devices, such as base stations (or node B), that can support communication for several user equipment (UEs). UEs can communicate with base stations via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the base station to the UE, and an uplink (or reverse link) refers to the communication link from the UE to the base station.
[0005] A base station may transmit data and control information to a UE on the downlink, or receive data and control information from a UE on the uplink. On the downlink, transmissions from the base station may be affected by interference from nearby base stations or other wireless radio frequency (RF) transmitters. On the uplink, transmissions from the UE may be affected by interference from uplink transmissions of other UEs communicating with nearby base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and uplink.
[0006] As the demand for mobile broadband access continues to increase, more users will access long-range wireless communication networks, and more short-range wireless systems will be deployed in areas, increasing the potential for interference and network congestion. Research and development to advance wireless technology continues not only to meet the growing demand for mobile broadband access, but also to evolve and improve the user experience of mobile communications.

[0017] Like reference numbers and designations in the various drawings indicate like elements. DETAILED DESCRIPTION
[0018] Wireless communication systems are increasingly supporting different types of devices with different capabilities. For example, a wireless communication system may include one or more user equipments (UEs) of a first capability type, and may further include one or more UEs of a second capability type that is different from the first capability type. In some implementations, the first capability type may correspond to a "reduced capability" (RedCap) capability type. In some implementations, a RedCap device may enable reduced cost, reduced device size, or reduced power consumption. The second capability type may correspond to a non-RedCap capability type, such as an enhanced mobile broadband (eMBB) capability type, an ultra-reliable low-latency communication (URLLC) capability type, or another capability type.
[0019] In some situations, a UE of one capability type may introduce noise or interference to another UE of another capability type. As an illustrative example, a RedCap UE may transmit a signal using frequencies in a first uplink bandwidth part (BWP) associated with the RedCap UE. In some cases, the first uplink BWP may overlap with (e.g., may be a subset of) a second uplink BWP associated with another UE, such as a non-RedCap UE. As a result, the frequencies used by the RedCap UE may be unavailable to the non-RedCap UE.
[0020] In some examples, a non-RedCap second uplink BWP may experience resource fragmentation resulting from the use of frequencies by a RedCap UE. For example, if the frequencies used by the RedCap UE include two frequency subsets of the second uplink BWP, the second uplink BWP may be fragmented into three non-contiguous frequency regions. In some implementations, transmission by a RedCap UE using three non-contiguous frequency regions may involve three different packets (rather than a single packet that may be transmitted using a single contiguous non-fragmented frequency region). As a result, latency associated with non-RedCap UEs may increase, which may be undesirable in some applications (such as in the case of some eMBB applications or URLLC applications).
[0021] In some aspects of the present disclosure, a UE may selectively enable or disable frequency hopping for uplink control channel transmission. In some situations, disabling frequency hopping may reduce or avoid resource fragmentation for a second UE. For example, if frequency hopping is disabled, the uplink control channel transmission may use one frequency subset of the first uplink BWP associated with the UE, instead of using multiple frequency subsets of the first uplink BWP. As a result, in some examples, resource fragmentation of the second uplink BWP associated with the second UE may be reduced. In some implementations, the frequency subset may be aligned with a frequency boundary of the second uplink BWP to further reduce or avoid resource fragmentation of the second uplink BWP.
[0022] Depending on the specific example, enabling or disabling frequency hopping may be done using explicit or implicit techniques. In one example of an explicit technique, a base station may transmit a frequency hopping indicator specifying whether frequency hopping is enabled or disabled for a UE. In some implementations, a base station may transmit a frequency hopping indicator based on the UE's capability type (e.g., an indication that the UE is associated with the RedCap capability type). For example, a UE might indicate its capability type in a message associated with a Random Access Channel (RACH) procedure, such as a Type 1 message (msg1) for a 4-step RACH procedure, a Type 3 message (msg3) for a 4-step RACH procedure, or a Type A message (msgA) for a 2-step RACH procedure. As an example for illustrative purposes, a base station might include a frequency hopping indicator in a Type 2 message (msg2) or Type 4 message (msg4) for a 4-step RACH procedure, a message scheduling msg2 or msg4, a Type B message (msgB) for a 2-step RACH procedure, a message scheduling msgB, or in a combination of downlink and control channels.
[0023] In implicit techniques, a UE may compare the first uplink BWP associated with the UE to a threshold based on the system bandwidth associated with the base station. If the first uplink BWP exceeds the threshold, the UE may enable frequency hopping for uplink control channel transmission. If the first uplink BWP does not exceed the threshold, the UE may disable frequency hopping for uplink control channel transmission. In some examples, the threshold corresponds to the product of the system bandwidth and a specific value. The specific value may be specified by the base station or by the wireless communication protocol, as an example for illustrative purposes.
[0024] By selectively disabling frequency hopping, the performance of one or more UEs may be improved. For example, disabling frequency hopping when the first uplink BWP of a RedCap UE is included in the second uplink BWP of a non-RedCap UE may reduce or avoid resource fragmentation associated with the second uplink BWP. As a result, the number of packets used by the non-RedCap UE to transmit data may be reduced, which may reduce latency in some situations.
[0025] To illustrate further, in various implementations, one or more embodiments described herein may be used for wireless communication networks such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, fifth-generation (5G) or new radio (NR) networks (which may be referred to as “5G NR” networks, systems, or devices), and other communication networks. The terms “network” and “system” as described herein may be used interchangeably.
[0026] For example, a CDMA network may implement wireless technologies such as Universal Terrestrial Radio Access (UTRA) and CDMA2000. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers the IS-2000, IS-95, and IS-856 standards.
[0027] TDMA networks may implement radio technologies such as the Global System for Mobile Communications (GSM). The Third Generation Partnership Project (3GPP®) defines standards for GSM EDGE (GSM Evolutionary High-Speed Data Rate) radio access networks (RANs), also known as GERAN. GERAN is a radio component of GSM / EDGE, along with the network connecting base stations (e.g., Ater interfaces and Abis interfaces) and base station controllers (e.g., A interfaces). The radio access network represents a component of the GSM network through which telephone calls and packet data are routed to and from the Public Switched Telephone Network (PSTN), and to the Internet, and to subscriber handsets, also known as user terminals or user equipment (UEs). A mobile operator's network may include one or more GERANs, and such GERANs may be coupled with UTRANs in the case of UMTS / GSM networks. In addition, an operator's network may also include one or more LTE networks or one or more other networks. Various different network types may use different radio access technologies (RATs) and RANs.
[0028] OFDMA networks can implement wireless technologies such as Advanced UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, and Flash OFDM. UTRA, E-UTRA, and GSM are part of the Universal Mobile Communications System (UMTS). Specifically, Long Term Evolution (LTE) is a UMTS release that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are documented in documents provided by an organization called the "Third Generation Partnership Project" (3GPP®), and cdma2000 is documented in documents from an organization called the "Third Generation Partnership Project 2" (3GPP® 2). These various wireless technologies and standards are known or under development. For example, 3GPP® is a collaborative effort among groups of telecommunications associations aimed at defining globally applicable third-generation (3G) mobile phone specifications. 3GPP® LTE is a 3GPP® project aimed at improving the UMTS mobile phone standard. 3GPP® may define specifications for next-generation mobile networks, mobile systems, and mobile devices. While this disclosure may describe several aspects with reference to LTE, 4G, or 5G NR technologies, the description is not intended to be limited to any particular technology or application, and one or more aspects described with reference to one technology may be understood to be applicable to other technologies as well. In addition, one or more aspects of this disclosure may relate to shared access to the wireless spectrum between networks using different radio access technologies or radio air interfaces.
[0029] 5G networks are intended to accommodate diverse deployments, diverse spectrums, and diverse services and devices, which can be implemented using an OFDM-based integrated air interface. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further extensions to LTE and LTE-A will be considered. 5G NR can scale to provide coverage for a large-scale Internet of Things (IoT) with (1) ultra-high density (e.g., ~1M nodes / km^2), ultra-low complexity (e.g., ~tens of bits / second), ultra-low energy (e.g., ~10+ year battery life), and deep coverage with the ability to reach hard-to-reach places; (2) mission-critical control with strong security to protect sensitive personal, financial, and confidential information, ultra-high reliability (e.g., ~approximately 99.9999% reliability), ultra-low latency (e.g., ~approximately 1 millisecond (ms)), and extensive mobility, including users with or without such mobility; and (3) extended mobile broadband with very high capacity (e.g., ~approximately 10 Tbps / km^2), very high data rates (e.g., multi-Gbps rates, user experience rates exceeding 100 Mbps), and deep awareness with advanced discovery and optimization.
[0030] Devices, networks, and systems may be configured to communicate over one or more parts of the electromagnetic spectrum. The electromagnetic spectrum is often subdivided into various classes, bands, channels, etc., based on frequency or wavelength. In 5G NR, two initial operating bands are identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are often referred to as intermediate band frequencies. Although a portion of FR1 is above 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers. A similar nomenclature issue can arise with respect to FR2, which is often referred to (interchangeably) as the "mmWave" band in documents and papers, even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) which is identified by the International Telecommunication Union (ITU) as the "mmWave" band.
[0031] With the above aspects in mind, unless otherwise specified, terms such as "sub-6GHz" may broadly refer to frequencies that are below 6GHz, within FR1, or may include intermediate band frequencies when used herein. Furthermore, unless otherwise specified, terms such as "mmWave" may broadly refer to frequencies that are midband frequencies, within FR2, or within the EHF band when used herein.
[0032] 5G NR devices, networks, and systems can be implemented to use optimized OFDM-based waveform features. These features may include scalable numerology and transmit time interval (TTI), a common flexible framework for efficiently multiplexing services and features in dynamic low-latency time-division duplex (TDD) or frequency-division duplex (FDD) designs, large-scale multiple-input multiple-output (MIMO), robust mmWave transmission, advanced channel coding, and advanced wireless technologies such as device-centric mobility. Numerology scalability in 5G NR, with subcarrier spacing scaling, can efficiently address the operation of diverse services across diverse spectrums and deployments. For example, in various outdoor and macro-coverage deployments of sub-3GHz FDD or TDD implementations, subcarrier spacing may occur at 15kHz across bandwidths such as 1, 5, 10, and 20MHz. For various other outdoor and small cell coverage deployments of TDD above 3 GHz, the subcarrier spacing can be 30 kHz over an 80 / 100 MHz bandwidth. For various other indoor broadband implementations using TDD in the unlicensed portion of the 5 GHz band, the subcarrier spacing can be 60 kHz over a 160 MHz bandwidth. Finally, for various deployments transmitting with millimeter-wave components in a 28 GHz TDD, the subcarrier spacing can be 120 kHz over a 500 MHz bandwidth.
[0033] 5G NR's scalable numerology facilitates scalable Time-to-Impact (TTI) for diverse latency and quality-of-service (QoS) requirements. For example, shorter TTIs may be used for lower latency and higher reliability, while longer TTIs may be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmissions to initiate on symbol boundaries. 5G NR also envisions a self-contained, integrated subframe design where uplink or downlink scheduling information, data, and acknowledgments are contained within the same subframe. Self-contained, integrated subframes support communications in unlicensed or competition-based shared spectrum and adaptive uplinks or downlinks that can be flexibly configured per cell to dynamically switch between uplinks and downlinks to meet current traffic needs.
[0034] For clarity, some aspects of the apparatus and techniques may be described below in relation to exemplary 5G NR implementations or in a 5G-centric manner, and 5G terminology may be used as illustrative examples in the following sections of the description. However, the description is not intended to be limited to 5G applications.
[0035] Furthermore, it should be understood that, during operation, a wireless communication network adapted according to the concepts herein may operate in any combination of licensed or unlicensed spectra depending on the load and availability. Therefore, it will be apparent to those skilled in the art that the systems, apparatus, and methods described herein may be applied to communication systems and applications other than the specific examples shown.
[0036] While this application illustrates several examples of embodiments and implementations, those skilled in the art will understand that additional implementations and use cases may arise in many different configurations and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, forms, sizes, and packaging arrangements. For example, implementations or applications may occur via integrated chip implementations or other non-modular component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail or purchasing devices, medical devices, AI-enabled devices, etc.). Some examples may or may not specifically target use cases or applications, but they may result in a wide range of applicability for the innovations described. Implementations can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the embodiments described herein. In some practical settings, devices incorporating the described embodiments and features may also necessarily include additional components and features for the implementation and practice of the claims and described embodiments. The innovations described herein can be implemented in a wide variety of implementation forms, including both large and small devices of various sizes, shapes, and structures, chip-level components, multi-component systems (e.g., radio frequency (RF) chains, communication interfaces, processors), distributed configurations, and end-user devices.
[0037] Figure 1 is a block diagram showing details of an exemplary wireless communication system in one or more embodiments. The wireless communication system may include a wireless network 100. The wireless network 100 may include, for example, a 5G wireless network. As will be understood by those skilled in the art, the components shown in Figure 1 are likely to have related corresponding parts, including other network configurations, such as cellular and non-cellular network configurations (e.g., device-to-device, peer-to-peer, or ad-hoc network configurations).
[0038] The wireless network 100 shown in Figure 1 includes several base stations 105 and other network entities. A base station may also be a station communicating with a UE, and may be referred to as an advanced node B (eNB), next-generation eNB (gNB), access point, etc. Each base station 105 may provide communication coverage for a specific geographic area. In 3GPP®, the term “cell” may refer to this specific geographic coverage area of a base station or base station subsystem serving a coverage area, depending on the context in which the term is used. In the implementations of the wireless network 100 herein, base stations 105 may be associated with the same operator or different operators (for example, the wireless network 100 may include multiple operator wireless networks). In addition, in the implementations of the wireless network 100 herein, base stations 105 may provide wireless communication using one or more of the same frequencies as adjacent cells (e.g., one or more frequency bands in the licensed spectrum, unlicensed spectrum, or a combination thereof). In some examples, individual base stations 105 or UE 115 may be operated by two or more network operating entities. In some other examples, each base station 105 and UE115 may be operated by a single network operations entity.
[0039] Base stations can provide communication coverage to macrocells, or small cells such as picocells or femtocells, or other types of cells. Macrocells generally cover relatively large geographical areas (e.g., a radius of several kilometers) and may enable unrestricted access by UEs (Users) subscribed to a network provider's service. Small cells, such as picocells, generally cover relatively small geographical areas and may enable unrestricted access by UEs subscribed to a network provider's service. Small cells, such as femtocells, also generally cover relatively small geographical areas (e.g., a home) and, in addition to unrestricted access, may also provide restricted access by UEs associated with the femtocell (e.g., UEs within a limited subscriber group (CSG), UEs for users in a home, etc.). Base stations for macrocells are sometimes called macro base stations. Base stations for small cells are sometimes called small cell base stations, pico base stations, femto base stations, or home base stations. In the example shown in Figure 1, base stations 105d and 105e are standard macro base stations, while base stations 105a–105c are macro base stations enabled with one of the following: 3D MIMO, full-dimension (FD) MIMO, or large-scale MIMO. Base stations 105a–105c leverage their higher-dimensional MIMO capabilities to utilize 3D beamforming in both high-altitude and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station that can be a home node or a portable access point. A base station may support one or more (e.g., two, three, or four) cells.
[0040] The wireless network 100 can support synchronous or asynchronous operation. In synchronous operation, base stations may have similar frame timings, and transmissions from different base stations may be approximately aligned in time. In asynchronous operation, base stations may have different frame timings, and transmissions from different base stations may not be aligned in time. In some scenarios, the network may be enabled or configured to handle dynamic switching between synchronous and asynchronous operation.
[0041] UE115 is distributed throughout the entire wireless network 100, and each UE may be fixed or mobile. Mobile devices are generally referred to as UEs in the standards and specifications published by 3GPP®, but it should be understood that such devices may also be referred to by those skilled in the art in additional or other ways as mobile station (MS), subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal (AT), mobile terminal, wireless terminal, remote terminal, handset, terminal, user agent, mobile client, client, game device, augmented reality device, vehicle component, vehicle device, or vehicle module, or any other appropriate term. For the purposes of this document, a “mobile” device or UE does not necessarily have to be mobile and may be fixed. Some non-exclusive examples of mobile devices that may have one or more implementations of UE115 include mobile phones, cellular phones, smartphones, Session Initiation Protocol (SIP) phones, wireless local loop (WLL) stations, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, and personal digital assistants (PDAs).Mobile devices may further include IoT or "All Internet of Things" (IoE) devices such as automobiles or other transport vehicles, satellite radios, Global Positioning System (GPS) devices, Global Navigation Satellite System (GNSS) devices, logistics controllers, drones, multicopters, quadcopters, smart energy or security devices, solar panels or solar arrays, urban lighting, water infrastructure, and other infrastructure; industrial automation and enterprise devices; consumer and wearable devices such as eyewear, wearable cameras, smartwatches, health or fitness trackers, mammalian implantable devices, gesture tracking devices, medical devices, digital audio players (e.g., MP3 players), cameras, and game consoles; and digital home or smart home devices such as home audio, video, and multimedia devices, home appliances, sensors, vending machines, intelligent lighting, home security systems, and smart meters. In one embodiment, the UE may be a device including a Universal Integrated Circuit Card (UICC). In another embodiment, the UE may be a device not including a UICC. In some embodiments, a UICC-free UE may also be called an IoE device. The UE115a to UE115d implementations shown in Figure 1 are examples of mobile smartphone-type devices accessing the wireless network 100. The UE can also be a machine specifically configured for connected communications, including machine-type communications (MTC), enhanced MTC (eMTC), and narrowband IoT (NB-IoT). The UE115e to UE115k shown in Figure 1 are examples of various machines configured for communications accessing the wireless network 100.
[0042] Mobile devices such as the UE115 may be able to communicate with all types of base stations, including macro base stations, pico base stations, femto base stations, and relays. In Figure 1, the communication links (represented as lightning bolts) show wireless transmissions between the UE and a serving base station, which is a base station designated to service the UE on the downlink or uplink, or desired transmissions between base stations, as well as backhaul transmissions between base stations. In some scenarios, the UE may act as a base station or other network node. Backhaul communication between base stations in wireless network 100 may be performed using wired or wireless communication links.
[0043] In operation within the wireless network 100, base stations 105a-105c serve UEs 115a and 115b using coordinated spatial techniques such as 3D beamforming and coordinated multipoint (CoMP) or multi-connectivity. Macro base station 105d performs backhaul communication with base stations 105a-105c and small cell base station 105f. Macro base station 105d also transmits multicast services that UEs 115c and 115d subscribe to and receive. Such multicast services may include mobile television or stream video, or other services to provide community information, such as weather emergencies or alerts such as amber alerts or gray alerts.
[0044] The implemented wireless network 100 supports mission-critical communications with highly reliable and redundant links for mission-critical devices such as the UE115e drone. The redundant communication links with the UE115e include those from macro base stations 105d and 105e, as well as from small cell base station 105f. Other machine-type devices such as the UE115f (thermometer), UE115g (smart meter), and UE115h (wearable device) can communicate through the wireless network 100, either directly with base stations such as the small cell base station 105f and macro base station 105e, or with other user devices that relay their information to the network in a multi-hop configuration. For example, the UE115f can communicate temperature measurement information to the smart meter UE115g, and then that information can be reported to the network via the small cell base station 105f. The wireless network 100 can also provide further network efficiency through dynamic low-latency TDD communication or low-latency FDD communication, such as in a vehicle-to-vehicle (V2V) mesh network between UE115i~115k communicating with macro base stations 105e.
[0045] In some aspects of this disclosure, the base station 105 in Figure 1 may transmit a frequency hopping (FH) indicator 150 to indicate to the UE 115 whether frequency hopping is enabled or disabled for the UE 115. For example, in some cases, the base station 105d may transmit the FH indicator 150 to the UE 115c to indicate whether frequency hopping is enabled or disabled for the UE 115c. The UE 115c may enable or disable frequency hopping based on the FH indicator 150, as will be further described below.
[0046] Figure 2 is a block diagram showing examples of base stations 105 and UEs 115 in one or more embodiments. Base stations 105 and UEs 115 may be any of the base stations and UEs in Figure 1. In the case of a limited association scenario (as described above), base station 105 may be the small cell base station 105f in Figure 1, and UE 115 may be a UE 115c or 115d operating in the service area of base station 105f, and UE 115c or 115d will be included in the list of UEs accessible to small cell base station 105f in order to access small cell base station 105f. Base station 105 may also be some other type of base station. As shown in Figure 2, base station 105 may be equipped with antennas 234a-234t, and UE 115 may be equipped with antennas 252a-252r to facilitate wireless communication.
[0047] At base station 105, the transmitting processor 220 may receive data from data source 212 and control information from processor 240, such as a processor. The control information may be for the Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid-ARQ (Automatic Retransmission Request) Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Extended Physical Downlink Control Channel (EPDCCH), MTC Physical Downlink Control Channel (MPDCCH), etc. The data may be for the Physical Downlink Shared Channel (PDSCH), etc. In addition, the transmitting processor 220 may process the data and control information (e.g., encoding and symbol mapping) to obtain data symbols and control symbols, respectively. The transmitting processor 220 may also generate reference symbols for, for example, the Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS), as well as cell-specific reference signals. The transmit (TX) MIMO processor 230 can, where applicable, perform spatial processing (e.g., precoding) on data symbols, control symbols, or reference symbols and supply the output symbol stream to modulators (MODs) 232a-232t. For example, spatial processing performed on data symbols, control symbols, or reference symbols may include precoding. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may, additionally or alternatively, process the output sample stream (e.g., convert to analog, amplify, filter, and upconvert) to obtain a downlink signal. The downlink signals from modulators 232a-232t may be transmitted via antennas 234a-234t, respectively.
[0048] In UE115, antennas 252a to 252r can receive downlink signals from base station 105 and each can provide the received signals to demodulators (DEMOD) 254a to 254r. Each demodulator 254 may adjust its respective received signal (e.g., filter, amplify, downconvert, and digitize) to obtain an input sample. Each demodulator 254 may further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbol from demodulators 254a to 254r, perform MIMO detection on the received symbol if applicable, and supply the detected symbol. The receiving processor 258 may process the detected symbol (e.g., demodulate, deinterleave, and decode) and provide the decoded data for UE115 to data sink 260 and the decoded control information to processor 280, such as a processor.
[0049] On the uplink, at UE115, the transmitting processor 264 can receive and process data from data source 262 (e.g., for a physical uplink shared channel (PUSCH)) and control information from processor 280 (e.g., for a physical uplink control channel (PUCCH)). In addition, the transmitting processor 264 can also generate reference symbols for reference signals. The symbols from the transmitting processor 264 can be precoded by the TX MIMO processor 266, where applicable, further processed by modulators 254a-254r (e.g., for SC-FDM), and transmitted to base station 105. At base station 105, the uplink signal from UE115 can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236, where applicable, and further processed by receiving processor 238 to obtain the decoded data and control information sent by UE115. The receiving processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the processor 240.
[0050] Processors 240 and 280 can direct operations in base station 105 and UE 115, respectively. Processor 240 or other processors and modules in base station 105, or processor 280 or other processors and modules in UE 115, can perform or direct the execution of various processes for the techniques described herein, such as performing or directing other processes, including the transmission and reception of the FH indicator 150, for the executions shown in Figures 8 to 11 or the techniques described herein. Memories 242 and 282 can store data and program code for base station 105 and UE 115, respectively. Scheduler 244 can schedule UEs for data transmission on downlink or uplink.
[0051] In some cases, the UE 115 and base station 105 may operate in a shared radio frequency spectrum band that may include licensed or unlicensed (e.g., contention-based) frequency spectra. In the unlicensed frequency portion of the shared radio frequency spectrum band, the UE 115 or base station 105 may conventionally perform medium sensing procedures to compete for access to the frequency spectrum. For example, the UE 115 or base station 105 may perform listen-before-talk (LBT) or listen-before-transmitting (LBT) procedures, such as a clear channel assessment (CCA), before communication to determine whether a shared channel is available. In some implementations, the CCA may include energy sensing procedures to determine whether there are any other active transmissions. For example, a device may infer that a change in the received signal strength indicator (RSSI) on a power meter indicates that the channel is occupied. Specifically, signal power concentrated within several bandwidths and exceeding a given noise floor may indicate another wireless transmitter. CCA may also include the detection of specific sequences indicating channel usage. For example, another device may send a specific preamble before sending a data sequence. In some cases, the LBT procedure may include a wireless node adjusting its own backoff window based on acknowledgment / negation (ACK / NACK) feedback to its own transmitted packets as a proxy for the amount of energy or collision detected on the channel.
[0052] Figure 3 is a block diagram showing an example of a wireless communication system 300 according to several aspects of the present disclosure. The wireless communication system 300 may include one or more base stations, such as base station 105. The wireless communication system 300 may further include one or more UEs, such as UE115x, UE115y, and UE115z. In some examples, UE115x~z correspond to UE115 shown in Figure 1.
[0053] The example in Figure 3 shows that the base station 105 may include one or more processors (such as processor 240) and may include memory 242. The base station 105 may further include a transmitter 306 and a receiver 308. Processor 240 may be coupled to memory 242, transmitter 306, and receiver 308. In some examples, the transmitter 306 and receiver 308 include one or more components described with reference to Figure 2, such as one or more of the modulator / demodulators 232a~t, MIMO detector 236, receiving processor 238, transmitting processor 220, or TX MIMO processor 230. In some implementations, the transmitter 306 and receiver 308 may be integrated into one or more transceivers of the base station 105.
[0054] The transmitter 306 may be configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 308 may be configured to receive reference signals, control information, and data from one or more other devices. For example, the transmitter 306 may be configured to transmit signaling, control information, and data to UE115x~z, and the receiver 308 may be configured to receive signaling, control information, and data from UE115x~z.
[0055] Each UE115x~z may include one or more processors (such as processor 280), memory (such as memory 282), a transmitter (such as transmitter 356), and a receiver (such as receiver 358). Processor 280 may be coupled with memory 282, transmitter 356, and receiver 358. In some examples, transmitter 356 and receiver 358 may include one or more components described with reference to Figure 2, such as one or more of modulators / demodulators 254a~r, MIMO detectors 256, receiving processor 258, transmitting processor 264, or TX MIMO processor 266. In some implementations, transmitter 356 and receiver 358 may be integrated into one or more transceivers of the UE115.
[0056] The transmitter 356 may be configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 358 may be configured to receive reference signals, control information, and data from one or more other devices. For example, in some implementations, the transmitter 356 may be configured to transmit signaling, control information, and data to the base station 105, and the receiver 358 may be configured to receive signaling, control information, and data from the base station 105.
[0057] In some implementations, one or more of the transmitter 306, receiver 308, transmitter 356, or receiver 358 may include an antenna array. An antenna array may include multiple antenna elements that perform wireless communication with other devices. In some implementations, an antenna array may perform wireless communication using different beams, also called antenna beams. Beams may include a transmit beam and a receive beam. For example, an antenna array may include multiple independent sets (or subsets) of antenna elements (or multiple individual antenna arrays), and each set of antenna elements in an antenna array may be configured to communicate using different beams, each having a different direction than the other beams. For example, a first set of antenna elements in an antenna array may be configured to communicate via a first beam having a first direction, and a second set of antenna elements in an antenna array may be configured to communicate via a second beam having a second direction. In other implementations, an antenna array may be configured to communicate via three or more beams. In some implementations, one or more sets of antenna elements in an antenna array may be configured to generate multiple beams simultaneously, for example, using multiple RF chains. A set (or subset) of antenna elements may include multiple antenna elements, such as two antenna elements, four antenna elements, ten antenna elements, twenty antenna elements, or any other number greater than two. Although described as an antenna array, in other implementations, an antenna array may include, or correspond to, multiple antenna panels, each of which may be configured to communicate using its own distinct beam.
[0058] In some implementations, the wireless communication system 300 operates in accordance with a 5G NR network. For example, the wireless communication system 300 may include multiple 5G-enabled UEs 115 and multiple 5G-enabled base stations 105, such as UEs and base stations configured to operate in accordance with a 5G NR network protocol, such as that defined by 3GPP®.
[0059] In some examples, one or more UE115s may be associated with a specific capability type. In some examples, UE115x and 115z may be associated with a first capability type, and UE115y may be associated with a second capability type different from the first capability type. In some implementations, the first capability type may correspond to a "Redcap" capability type, and the second capability type may correspond to a non-Redcap capability type, such as an embedded mobile broadband (eMBB) capability type, an ultra-high reliability low latency communication (URLLC) capability type, or another capability type. In some examples, UE115x and UE115z may correspond to wearable devices, medical surveillance devices, sensor devices, Internet of Things (IoT) devices, or smart city devices (such as surveillance cameras), as illustrative examples.
[0060] To illustrate further, in some implementations, the UE115x, UE115y, and UE115z may communicate with base station 105 using a first uplink bandwidth portion (BWP) 362 (e.g., the default uplink BWP for the UE115x), a second uplink BWP 372, and a third uplink BWP 382, respectively. In some examples, the first uplink BWP 362 and the third uplink BWP 382 contain less bandwidth than the second uplink BWP 372 (e.g., to reduce power consumption associated with the UE115x and UE115z). Each of the uplink BWPs 362, 372, and 382 may correspond to an initial uplink BWP or an active uplink BWP. For example, the first uplink BWP 362 may correspond to an initial uplink BWP used by the UE115x before establishing a radio resource control (RRC) connection between base station 105 and the UE115x. In some other examples, the first uplink BWP362 may correspond to an active uplink BWP configured by base station 105 after establishing an RRC connection between base station 105 and UE115x.
[0061] During operation, transmitter 356 may operate based on the first uplink BWP 362. For example, transmitter 356 may be configured to transmit an uplink control channel transmission 330 located in the first uplink BWP 362 to base station 105 (for example, the uplink control channel transmission 330 is transmitted using the frequency resources included in the first uplink BWP 362). The uplink control channel transmission 330 may indicate uplink control information (UCI) 334 associated with the UE 115x. In some examples, the uplink control channel transmission 330 corresponds to a physical uplink control channel (PUCCH) transmission.
[0062] In some implementations, the transmitter 356 may be configured to perform uplink control channel transmission 330 based on FH mode 360. While operating based on FH mode 360, the transmitter 356 may switch (or "hop") between transmitting using a first frequency subset 364 of the first uplink BWP 362 and transmitting using a second frequency subset 366 of the first uplink BWP 362. In some situations, performing uplink control channel transmission 330 based on FH mode 360 may be associated with performance degradation of one or more other UEs 115, such as resource fragmentation.
[0063] For example, Figure 4 shows an example of a resource allocation scheme 400 according to several aspects of the present disclosure. In the example of resource allocation scheme 400, the first uplink BWP 362 is smaller than the second uplink BWP 372 (for example, including a smaller frequency range than the second uplink BWP 372). During the operation of the transmitter 356 based on FH mode 360, the UE 115y may experience resource fragmentation. For example, if the transmitter 356 uses the first frequency subset 364 and the second frequency subset 366 during FH mode 360, the frequencies corresponding to the first frequency subset 364 and the second frequency subset 366 may be unavailable (or not assigned) to the UE 115y. As a result, the resources of the second uplink BWP 372 may be separated (or fragmented) into three discontinuous frequency ranges.
[0064] In some aspects of this disclosure, base station 105 may transmit an FH indicator 150 to selectively enable or disable FH mode 360. Disabling FH mode 360 can reduce or avoid resource fragmentation of the second uplink BWP 372. For example, when FH mode 360 is disabled, UE 115x may perform an uplink control channel transmission 330 based on one (but not both) of the first frequency subset 364 or the second frequency subset 366, thereby reducing or avoiding fragmentation of the second uplink BWP 372.
[0065] To illustrate further, referring again to Figure 3, base station 105 may send one or more messages 320, including an FH indicator 150, to UE115x. In some examples, UE115x sends a message 310 to base station 105 indicating the capability type 314 of UE115x, and base station 105 sends the FH indicator 150 to UE115x based on the capability type 314. In some examples, capability type 314 indicates that UE115x corresponds to a RedCap UE. In such examples, capability type 314 may correspond to a RedCap capability type, which in some implementations may be associated with a reduced uplink bandwidth compared to at least one other capability type, such as an eMBB capability type or a URLLC capability type. Alternatively or additionally, capability type 314 may indicate one or more other parameters, such as one or more of the bandwidth or center frequency of the first uplink BWP 362, as an example for illustrative purposes.
[0066] In some examples, message 310 corresponds to a type 1 message (msg1) associated with a 4-step random access channel (RACH) procedure 342 (e.g., a competition-based RACH procedure) indicating capability type 314. In some such examples, one or more messages 320 may include, or correspond to, a type 4 message (msg4) associated with the 4-step RACH procedure 342, a downlink control channel transmission scheduling msg4, or a combination of a downlink control channel transmission and a downlink data channel transmission. In relation to the combination of a downlink control channel transmission and a downlink data channel transmission, at least a first bit of the FH indicator 150 is included in the downlink control channel transmission, and at least a second bit of the FH indicator 150 is included in the downlink data channel transmission. In such examples, the UE 115x may perform joint decoding or concatenation of the downlink control channel transmission and the downlink data channel transmission to identify the FH indicator 150, thereby improving the reliability of the transmission of the FH indicator 150 in some situations.
[0067] In some other examples, message 310 corresponds to a type 3 message (msg3) associated with a 4-step RACH procedure 342 and having one of the following: a demodulated reference signal (DMRS) configuration indicating capability type 314, a payload indicating capability type 314, or a scrambling identifier indicating capability type 314. In some such examples, one or more messages 320 may include, or correspond to, a message 4 (msg4) associated with the 4-step RACH procedure 342, a downlink control channel transmission scheduling msg4, or a combination of a downlink control channel transmission and a downlink data channel transmission.
[0068] In some other examples, message 310 corresponds to a type A message (msgA) associated with a two-step RACH procedure 344 (e.g., a no-conflict RACH procedure) and having one of the following: a preamble indicating capability type 314, a DMRS configuration indicating capability type 314, a payload indicating capability type 314, or a scrambling identifier for a payload indicating capability type 314. In some such examples, one or more messages 320 may include, or correspond to, a type B message (msgB) associated with a two-step RACH procedure 344, a downlink control channel message scheduling msgB, or a combination of downlink control channel transmission and downlink data channel transmission.
[0069] To illustrate further, in an example of the 4-step RACH procedure 342, UE115x may send msg1 to indicate the random access preamble selected by UE115x, and base station 105 may send msg2 to indicate the response to the random access preamble, including the uplink resource allocation. UE115x may send msg3 to base station 105 using the uplink resource allocation, and base station 105 may send a conflict resolution message to UE115x via msg4. In an example of the 2-step RACH procedure 344, base station 105 may assign a random access preamble to UE115x and indicate the assigned random access preamble to UE115x. UE115x may send the assigned random access preamble to base station 105 via msgA, and base station 105 may send a random access response to msgA to UE115x via msgB.
[0070] In some other examples, one or more messages 320 may contain or correspond to other messages sent regardless of the RACH type associated with the UE115x. For example, one or more messages 320 may contain or correspond to system information (SI) messages associated with the base station 105. In some examples, the base station 105 transmits SI messages using a broadcast technique that may allow multiple UEs (such as UE115x~z) to receive the SI messages.
[0071] The FH indicator 150 may include a bit 324 having a value indicating whether FH mode 360 is enabled or disabled. For example, bit 324 may indicate a first value, and the transmitter 356 may perform the uplink control channel transmission 330 using FH mode 360 based on the first value of bit 324. In some other examples, bit 324 may indicate a second value different from the first value, and the transmitter may disable FH mode 360 for the uplink control channel transmission 330 based on the second value of bit 324. In such examples, the transmitter 356 may perform the uplink control channel transmission 330 using one (but not both) of the first frequency subset 364 or the second frequency subset 366. In some implementations, the first value corresponds to a logical 0 value and the second value corresponds to a logical 1 value. In some other implementations, the first value corresponds to a logical 1 value and the second value corresponds to a logical 0 value.
[0072] In some implementations, the FH indicator 150 may optionally include a first group of one or more bits 326 that indicates a resource set 346 in the first uplink BWP 362. For example, memory 282 may store a table of resource sets, and the first group of one or more bits 326 may correspond to an index on the table of resource sets. The processor 280 may identify the resource set 346 based on the first group of one or more bits 326, and the transmitter 356 may perform an uplink control channel transmission 330 based on the resource set 374. In some examples, the first group of one or more bits 326 may indicate a first frequency subset 364, a second frequency subset 366, or other frequency resources contained in the first uplink BWP 362.
[0073] In some examples, at least a subset of resource set 346 is shared with or partially overlaps with at least one other resource set of at least one other device having the same or different capability types as UE115x. For example, resource set 346 may include at least one common resource as resource set 374 for UE115y, and UE115y may have a different capability type than UE115x. In another example, resource set 346 may include at least one common resource as resource set 384 for UE115z, and UE115z may have the same capability type as UE115x. In some examples, resource set 374 may correspond to the initial uplink BWP or active uplink BWP of UE115y, and resource set 384 may correspond to the initial uplink BWP or active uplink BWP of UE115z.
[0074] In some other examples, resource set 346 is separate from one or more other resource sets of at least one other device having the same or different capability types as UE115x. For example, resource set 346 may be separate from resource set 374 of UE115y (and may not contain at least one common resource), and UE115y may have different capability types than UE115x. Another example is resource set 346, which may be separate from resource set 384 of UE115z, and UE115z may have the same capability types as UE115x.
[0075] Alternatively or additionally, the FH indicator 150 may optionally include a second group 328 of one or more bits indicating the number of iterations 348, and the transmitter 356 may perform one or more iterations 332 of the uplink control channel transmit 330 based on the number of iterations 348. In some examples, performing one or more iterations 332 may improve the reliability associated with the uplink control channel transmit 330. For example, the frequency diversity gain associated with the uplink control channel transmit 330 may be reduced by disabling the FH mode 360, and the reduced frequency diversity gain may be compensated by performing one or more iterations 332 (for example, by increasing the time diversity gain associated with the uplink control channel transmit 330).
[0076] In some examples, base station 105 transmits one or more messages 320 using broadcast transmission techniques. Depending on the specific example, base station 105 may transmit one or more messages 320 (e.g., using broadcast transmission techniques) before or after the initial access procedure by UE 115x. The initial access procedure may include establishing an RRC connection between base station 105 and UE 115. In some other examples, base station 105 transmits one or more messages 320 using unicast transmission techniques. Depending on the specific example, base station 105 may transmit one or more messages 320 using unicast transmission techniques and using either an RRC connection or media access control (MAC) control element (MAC-CE) signaling.
[0077] While some examples of the uplink control channel transmit 330 may be described as a single signal or single transmit, in some other examples the uplink control channel transmit 330 may include multiple uplink signals within a first uplink BWP 362. In such examples, bits of UCI 334 may be allocated (or "shared") among multiple uplink signals within the first uplink BWP 362. Furthermore, the FH indicator 150 may be shared among multiple uplink signals (for example, by enabling or disabling FH mode 360 for each of the multiple uplink signals based on the value of bit 324). In some examples the multiple uplink signals include, as an example for illustrative purposes, one or more of the following: a physical uplink control channel (PUCCH) signal, a physical uplink shared channel (PUSCH) signal, a sounding reference signal (SRS), or a physical random access channel (PRACH) signal.
[0078] Figure 5 shows examples of a first uplink BWP 362, a second uplink BWP 372, and a third uplink BWP 382 according to several aspects of the present disclosure. Figure 5 shows that a first frequency subset 364 of the first uplink BWP 362 may be aligned with a first boundary 502 of the second uplink BWP 372 (e.g., the lowest frequency included in the second uplink BWP 372).
[0079] By aligning the first frequency subset 364 with the first boundary 502 of the second uplink BWP 372, resource fragmentation of the second uplink BWP 372 during the operation of the transmitter 356 based on FH mode 360 can be reduced or avoided. For example, if the resources of the first frequency subset 364 are unavailable to the UE 115y during the uplink control channel transmission 330, a contiguous group of resources 504 may be available to the UE 115y (e.g., rather than multiple discontinuous groups of resources that may result from resource fragmentation). In some examples, the number of packets transmitted by the UE 115y can be reduced by reducing or avoiding resource fragmentation (e.g., by enabling the transmission of data in a single packet using a contiguous group of resources 504 instead of using multiple packets using multiple discontinuous groups of resources). As a result, data throughput and performance may be improved.
[0080] The example in Figure 5 also shows that the first frequency subset 364 can be aligned with the third frequency subset 506 of the third uplink BWP 382 associated with the third device (e.g., UE115z). As a result, resource fragmentation for the second uplink BWP 372 caused by transmission by the UE115z using the third frequency subset 506 can be reduced or avoided.
[0081] Figure 6 shows examples of additional first uplink BWP 362, second uplink BWP 372, and third uplink BWP 382 according to some aspects of the present disclosure. Figure 6 shows that the second boundary 602 of the second uplink BWP 372 may be aligned with a fourth frequency subset 606 of the third uplink BWP 382 associated with a third device (e.g., UE115z). In some implementations, the example in Figure 6 may reduce interference between the transmissions of UE115x and UE115y (due to the use of different frequency subsets 364, 606 for transmission), while also enabling a contiguous group of resources 604 for UE115y, and thus reducing or avoiding resource fragmentation for UE115y.
[0082] Referring again to Figure 3, in some examples, the base station 105 sets the FH indicator 150 based on the resource allocation 302. The resource allocation 302 may track or indicate resources allocated to the UEs of the wireless communication system 300, such as UEs 115x~z. As an example for illustrative purposes, if the first uplink BWP 362 is included in the second uplink BWP 372, the base station 105 may set the FH indicator 150 to indicate the disabling of FH mode 360 and optionally indicate the use of resources in the second frequency subset 366 via a first group of one or more bits 326. Alternatively or additionally, base station 105 may perform uplink BWP alignment based on resource allocation 302 by aligning frequency subsets 364 and 506 with a first boundary 502, or by aligning the first frequency subset 364 with the first boundary 502 and aligning the fourth frequency subset 606 with a second boundary 602, etc.
[0083] While certain examples have been described using explicit FH instruction techniques (such as using bit 324), in some other examples, UE115 may determine whether FH should be performed according to implicit FH instruction techniques. Implicit FH instruction techniques may be used instead of or in addition to explicit FH instruction techniques. For example, in some implementations, if UE115x does not receive an explicit instruction for FH indicator 150 from base station 105, UE115x may use implicit FH instruction techniques to determine whether FH mode 360 should be enabled or disabled. Examples of implicit FH instruction techniques are further illustrated with reference to Figure 7.
[0084] Figure 7 is a block diagram showing another example of a wireless communication system 700 according to some aspects of the present disclosure. The wireless communication system 700 may include one or more base stations, such as base station 105. The wireless communication system 300 may further include one or more UEs, such as UE115x, UE115y, and UE115z.
[0085] During operation, base station 105 may transmit an instruction for a bandwidth 712 associated with base station 105, such as the serving cell system bandwidth associated with base station 105. In some examples, base station 105 may transmit a system information (SI) message 710 containing a first instruction for bandwidth 712. Base station 105 may transmit the first instruction for bandwidth 712 using broadcast transmission techniques.
[0086] One or more of the UE115x~z may receive a first instruction for bandwidth 712 and decode the first instruction to identify bandwidth 712. For example, UE115x may receive an SI message 710 and decode the SI message 710 to identify bandwidth 712.
[0087] The base station 105 may transmit a second instruction for the first uplink BWP 362 associated with the UE 115x. In some examples, the second instruction for the first uplink BWP 362 is included in the SI message 710. In some such examples, the UE 115x may decode the SI message 710 to identify the first uplink BWP 362. In some other examples, the second instruction for the first uplink BWP 362 is included in the RRC configuration message 720 sent to the UE 115x by the base station 105 after establishing an RRC connection with the UE 115x. In some such examples, the UE 115x may decode the RRC configuration message 720 to identify the first uplink BWP 362. In some other examples, the second instruction for the first uplink BWP 362 may be included in a separate message. Depending on the specific example, the first uplink BWP 362 may correspond to the initial BWP of the UE 115x or the active BWP of the UE 115x.
[0088] In some aspects of this disclosure, the UE115x may determine whether the first uplink BWP362 exceeds a threshold of 750. For example, the processor 280 may compare a first number of Hertz (Hz) corresponding to the first uplink BWP362 with a second number of Hz corresponding to the threshold of 750 in order to determine whether the first uplink BWP362 exceeds a threshold of 750. The threshold of 750 may be based at least in part on the bandwidth 712.
[0089] The UE115x may enable (or disable) FH mode 360 based on whether the first uplink BWP 362 exceeds (or does not exceed) the threshold 750. For example, in some cases, the processor 280 may determine that the first uplink BWP 362 exceeds the threshold 750. In such cases, the processor 280 may enable FH mode 360, and the transmitter 356 may perform uplink control channel transmission 330 based on FH mode 360. In some other cases, the processor 280 may determine that the first uplink BWP 362 does not exceed the threshold 750. In such cases, the processor 280 may disable FH mode 360, and the transmitter 356 may perform uplink control channel transmission 330 without using FH mode 360.
[0090] In some implementations, the threshold 750 is based on the bandwidth 712 and the parameter 752 (e.g., a coefficient that has a positive or non-negative value). In some examples, the threshold 750 corresponds to the product of the bandwidth 712 and the parameter 752. In some implementations, the parameter 752 is determined by the network device (e.g., base station 105) and indicated to the UE115x in system information (e.g., via SI message 710) or using RRC signaling (e.g., via RRC configuration message 720 or another message). In some other examples, the base station 105 and the UE115x operate according to a wireless communication protocol (e.g., 5G NR wireless communication protocol), and the wireless communication protocol specifies the parameter 752 based on one or more of the following: bandwidth 712, the maximum bandwidth associated with the device type (e.g., the maximum bandwidth supported by capability type 314 in Figure 3), or a first uplink BWP 362 configured by the network device based on the device type.
[0091] In some examples, one or more of the first frequency subset 364 or the second frequency subset 366 includes a first contiguous group of one or more physical resource blocks (PRBs). For the sake of non-restrictive explanation, the first frequency subset 364 may include a contiguous group of two consecutive PRBs, and the second frequency subset 366 may include a contiguous group of three consecutive PRBs.
[0092] In some examples, one or more of the first frequency subset 364 or the second frequency subset 366 extends to either a second consecutive group of symbols in a slot or a third consecutive group of symbols in multiple slots. For example, if one or more of the first frequency subset 364 or the second frequency subset 366 extends to a consecutive group of symbols in a slot, FH mode 360 may correspond to, or be called, an intra-slot frequency hopping mode. If one or more of the first frequency subset 364 or the second frequency subset 366 extends to a consecutive group of symbols in multiple slots, FH mode 360 may correspond to, or be called, an inter-slot frequency hopping mode.
[0093] In some examples, the first frequency subset 364 does not overlap with the second frequency subset 366. For example, when FH mode 360 is enabled for the uplink control channel transmit 330 in the first uplink BWP 362, the PRB of the first frequency subset 364 does not have to overlap with (and may not include) the PRB of the second frequency subset 366.
[0094] One or more examples described herein may improve the performance of one or more UEs, such as UE115y. For example, resource fragmentation associated with the second uplink BWP372 may be reduced or avoided by disabling FH mode 360 when one or more of the first uplink BWP362 are included in the second uplink BWP372. As a result, the number of packets used by UE115y to transmit data to base station 105 may be reduced, which may reduce latency in some situations.
[0095] Figure 8 is a flowchart illustrating an example of wireless communication method 800 performed by a UE in several embodiments. In some embodiments, method 800 is performed by a UE 115.
[0096] Method 800 includes, in 802, receiving one or more messages from the base station that include a frequency hopping indicator indicating whether a frequency hopping mode is enabled or disabled for the UE. The UE is associated with a first uplink BWP that includes a first frequency subset and a second frequency subset. For example, UE 115x may receive an FH indicator 150 (e.g., using receiver 358) indicating whether FH mode 360 is enabled or disabled for UE 115x.
[0097] Method 800 further includes, in 804, transmitting an uplink control channel transmission to a base station. The uplink control channel transmission is transmitted using both a first frequency subset and a second frequency subset based on the frequency hopping indicator indicating that a frequency hopping mode is enabled, or using one of the first frequency subset or the second frequency subset based on the frequency hopping indicator indicating that a frequency hopping mode is disabled. For example, based on the FH indicator 150 indicating that FH mode 360 is enabled, the UE 115x may perform the uplink control channel transmission 330 using both the first frequency subset 364 and the second frequency subset 366 (e.g., using transmitter 356), such as by changing (or "hopping") between transmitting using the first frequency subset 364 and transmitting using the second frequency subset 366. In some other examples, based on the FH indicator 150 indicating that FH mode 360 is disabled, the UE115x may perform an uplink control channel transmission 330 (for example, using transmitter 356) using either (but not both) of the first frequency subset 364 or the second frequency subset 366.
[0098] Figure 9 is a flowchart illustrating an example of a wireless communication method 900 performed by a base station in several embodiments. In some embodiments, the method 900 is performed by a base station 105.
[0099] Method 900 includes, in 902, sending to the UE one or more messages including a frequency hopping indicator that specifies whether a frequency hopping mode is enabled or disabled for the UE. The UE is associated with a first uplink BWP including a first frequency subset and a second frequency subset. For example, base station 105 may transmit an FH indicator 150 (e.g., using transmitter 306) indicating whether FH mode 360 is enabled or disabled for the UE 115x.
[0100] Method 900 further includes, in 904, receiving an uplink control channel transmission from the UE. The uplink control channel transmission is received using both the first and second frequency subsets based on the frequency hopping indicator indicating that frequency hopping mode is enabled, or using one of the first or second frequency subsets based on the frequency hopping indicator indicating that frequency hopping mode is disabled. For example, based on the FH indicator 150 indicating that FH mode 360 is enabled, base station 105 may receive the uplink control channel transmission 330 using both the first frequency subset 364 and the second frequency subset 366 (e.g., using receiver 308), by changing or "hopping" between transmitting using the first frequency subset 364 and receiving using the second frequency subset 366. In some other examples, based on the FH indicator 150 indicating that FH mode 360 is disabled, base station 105 may receive the uplink control channel transmission 330 (for example, using receiver 308) using either (but not both) of the first frequency subset 364 or the second frequency subset 366.
[0101] Figure 10 is a flowchart illustrating an example of wireless communication method 1000 performed by a UE in several embodiments. In some embodiments, method 1000 is performed by a UE 115.
[0102] Method 1000 includes, in 1002, receiving a first instruction from the base station regarding the bandwidth associated with the base station.
[0103] Method 1000 further includes, in 1004, receiving a second instruction for a first uplink BWP from a base station. The first uplink BWP includes a first frequency subset and further includes a second frequency subset.
[0104] Method 1000 further includes transmitting an uplink signal transmission to a base station in 1006. The uplink signal transmission is transmitted using both a first frequency subset and a second frequency subset based on the first uplink BWP exceeding a threshold based at least in part on the bandwidth associated with the base station, or using one of the first frequency subset or the second frequency subset based on the first uplink BWP not exceeding the threshold.
[0105] Figure 11 is a flowchart illustrating an example of a wireless communication method 1100 performed by a base station in several embodiments. In some embodiments, the method 1100 is performed by a base station 105.
[0106] Method 1100 includes, in 1102, transmitting to the UE a first instruction regarding the bandwidth associated with the base station.
[0107] Method 1100 further includes, in 1104, transmitting a second instruction for the first uplink BWP to the UE. The first uplink BWP includes a first frequency subset and further includes a second frequency subset.
[0108] Method 1100 further includes receiving an uplink signal transmission from the UE in 1106. The uplink signal transmission is received using both a first and a second frequency subset based on the first uplink BWP exceeding a threshold based at least in part on the bandwidth associated with the base station, or using one of the first or second frequency subset based on the first uplink BWP not exceeding the threshold.
[0109] Figure 12 is a block diagram showing an example of UE115 according to several aspects of the present disclosure. UE115 may include the structure, hardware, or components shown in Figure 2. For example, UE115 may include a processor 280 capable of executing instructions stored in memory 282. Using the processor 280, UE115 may transmit and receive signals via wireless radios 1210a-r and antennas 252a-r. Wireless radios 1201a-r may include one or more components or devices described herein, such as modulators / demodulators 254a-r, MIMO detectors 256, receiving processors 258, transmitting processors 264, TX MIMO processors 266, transmitters 356, and receivers 358, or one or more other components or devices.
[0110] In some implementations, memory 282 may store an FH mode determination instruction 1202 that can be executed by the processor 280 to determine whether FH mode 360 should be enabled or disabled (for example, based on the value of bit 324 of the FH indicator 150). Memory 282 may store an FH transmit instruction 1204 that can be executed by the processor 280 to perform an uplink control channel transmit 330 using FH mode 360, based on the FH indicator 150 indicating that FH mode 360 should be enabled. Memory 282 may store a non-FH transmit instruction 1206 that can be executed by the processor 280 to perform an uplink control channel transmit 330 without using FH mode 360, based on the FH indicator 150 indicating that FH mode 360 should be disabled.
[0111] Figure 13 is a block diagram showing an example of a base station 105 according to several aspects of the present disclosure. The base station 105 may include the structure, hardware, and components shown in Figure 2. For example, the base station 105 may include a processor 240 capable of executing instructions stored in memory 242. Under the control of the processor 240, the base station 105 may transmit and receive signals via wireless radios 1301a-t and antennas 234a-t. The wireless radios 1301a-t may include one or more components or devices described herein, such as modulators / demodulators 232a-t, MIMO detectors 236, receiving processors 238, transmitting processors 220, TX MIMO processors 230, transmitters 306, and receivers 308, or one or more other components or devices.
[0112] In some implementations, memory 242 may store an FH mode determination instruction 1302 that can be executed by the processor 240 to select whether to enable or disable FH mode 360 (for example, by setting the value of bit 324 of the FH indicator 150, which can be based on resource allocation 302). Depending on whether the FH indicator 150 indicates that FH mode 360 should be enabled, memory 242 may store an FH receive instruction 1304 that can be executed by the processor 240 to receive the uplink control channel transmission 330 based on FH mode 360. Depending on whether the FH indicator 150 indicates that FH mode 360 should be disabled, memory 242 may store a non-FH receive instruction 1306 that can be executed by the processor 240 to receive the uplink control channel transmission 330 without using FH mode 360.
