[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. patent application Ser. No. 17 / 651,366, entitled "FREQUENCY HOPPING ENABLING FOR AN UPLINK CONTROL CHANNEL TRANSMISSION BY A USER EQUIPMENT," filed on February 16, 2022, and U.S. Provisional Patent Application No. 63 / 260,038, entitled "FREQUENCY HOPPING ENABLING FOR AN UPLINK CONTROL CHANNEL TRANSMISSION BY A USER EQUIPMENT," filed on August 6, 2021, the entireties of which are expressly incorporated by reference herein.

[0002] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to communication systems that use frequency hopping for wireless transmissions. [Background technology]

[0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcasts, 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 supporting communication 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 Bs), that can support communication for several user equipments (UEs). The UEs may communicate with the base stations via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the 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 a base station may experience interference due to transmissions from neighboring base stations or from other wireless radio frequency (RF) transmitters. On the uplink, transmissions from a UE may experience interference from uplink transmissions of other UEs communicating with neighboring base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and the uplink.

[0006] As the demand for mobile broadband access continues to increase, more UEs access long-range wireless communication networks and more short-range wireless systems are deployed in areas, increasing the potential for interference and network congestion. Research and development continues to advance wireless technologies to not only 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 OF THE PREFERRED EMBODIMENTS

[0018] Wireless communication systems increasingly support different types of devices having 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 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 embedded mobile broadband (eMBB) capability type, an ultra-reliable low latency communications (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 a frequency within a first uplink bandwidth portion (BWP) associated with the RedCap UE. In some cases, the first uplink BWP may overlap with (e.g., be a subset of) a second uplink BWP associated with another UE, such as a non-RedCap UE. As a result, the frequency used by the RedCap UE may be unavailable to the non-RedCap UE.

[0020] In some examples, the second uplink BWP of a non-RedCap may experience resource fragmentation due to the use of frequencies by the RedCap UE. For example, if the frequency used by the RedCap UE includes two frequency subsets of the second uplink BWP, the second uplink BWP may be fragmented into three non-contiguous frequency regions. In some implementations, a transmission by a RedCap UE using three non-contiguous frequency regions may involve three different packets (e.g., rather than a single packet that may be transmitted using a single contiguous non-fragmented frequency region). As a result, the latency associated with the non-RedCap UE may increase, which may be undesirable in some applications (such as in some eMBB or URLLC applications).

[0021] In some aspects of the disclosure, the UE may selectively enable or disable frequency hopping for uplink control channel transmissions. In some circumstances, disabling frequency hopping may reduce or avoid resource fragmentation for the second UE. For example, when 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 subsets may be aligned with frequency boundaries of the second uplink BWP to further reduce or avoid resource fragmentation of the second uplink BWP.

[0022] Depending on the particular example, enabling or disabling frequency hopping may be performed using explicit or implicit techniques. In one example of an explicit technique, the base station may transmit a frequency hopping indicator that specifies whether frequency hopping is enabled or disabled for the UE. In some implementations, the base station may transmit the frequency hopping indicator based on the UE's capability type (e.g., an indication that the UE is associated with a RedCap capability type). To illustrate, the UE may indicate the capability type in a message associated with a random access channel (RACH) procedure, such as a type 1 message (msg1) of a four-step RACH procedure, a type 3 message (msg3) of a four-step RACH procedure, or a type A message (msgA) of a two-step RACH procedure. The base station may include the frequency hopping indicator in a type 2 message (msg2) or a type 4 message (msg4) of a four-step RACH procedure, a message scheduling msg2 or msg4, a type B message (msgB) of a two-step RACH procedure, a message scheduling msgB, or a combination of a downlink channel and a control channel, as illustrative examples.

[0023] In the implicit technique, the UE may compare a first uplink BWP associated with the UE to a threshold based on a 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 transmissions. If the first uplink BWP does not exceed the threshold, the UE may disable frequency hopping for uplink control channel transmissions. In some examples, the threshold corresponds to a product of the system bandwidth and a specific value. The specific value may be specified by the base station or by a wireless communication protocol, as an illustrative example.

[0024] By selectively disabling frequency hopping, the performance of one or more UEs may be improved. For example, by disabling frequency hopping in one or more cases where a first uplink BWP of a RedCap UE is included in a second uplink BWP of a non-RedCap UE, resource fragmentation associated with the second uplink BWP may be reduced or avoided. 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 further illustrate, in various implementations, one or more aspects described herein may be used for wireless communications 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 communications networks. The terms "network" and "system" as described herein may be used interchangeably.

[0026] For example, a CDMA network may implement a radio technology such as universal terrestrial radio access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers IS-2000, IS-95, and IS-856 standards.

[0027] The TDMA network may implement a radio technology such as, for example, Global System for Mobile Communications (GSM). The 3rd Generation Partnership Project (3GPP) defines standards for the GSM EDGE (Enhanced Data Rates for GSM Evolution) Radio Access Network (RAN), also denoted as GERAN. The GERAN is the radio component of GSM / EDGE, along with the network that connects the base stations (e.g., Ater and Abis interfaces) and the base station controllers (such as the A interface). The radio access network represents the component of the GSM network through which telephone calls and packet data are routed to and from the Public Switched Telephone Network (PSTN) and the Internet to and from the subscriber handsets, also known as user terminals or user equipment (UE). A mobile operator's network may include one or more GERANs, which may be combined with a UTRAN in the case of a UMTS / GSM network. In addition, the operator 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 may implement radio technologies such as Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, Flash OFDM, etc. UTRA, E-UTRA, and GSM are parts of the Universal Mobile Telecommunications System (UMTS). Specifically, long term evolution (LTE) is a release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents from an organization named "3rd Generation Partnership Project" (3GPP®), and cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP®2). These various radio technologies and standards are known or under development. For example, 3GPP® is a collaboration between groups of telecommunications associations whose purpose is to define 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. Although the present disclosure may describe some aspects with reference to LTE, 4G, or 5G NR technology, the description is not intended to be limited to a particular technology or application, and it may be understood that one or more aspects described with reference to one technology may also be applicable to another technology. Additionally, one or more aspects of the present disclosure may relate to shared access to a wireless spectrum between networks using different radio access technologies or radio air interfaces.

[0029] 5G networks contemplate diverse deployments, diverse spectrum, and diverse services and devices that can be implemented using an OFDM-based unified air interface. To achieve these goals, further enhancements to LTE and LTE-A are being considered, in addition to the development of new radio technologies for 5G NR networks. 5G NR can scale to provide coverage for (1) massive Internet of Things (IoT) with ultra-high density (e.g., ~1M nodes / km^2), ultra-low complexity (e.g., ~tens of bits / sec), ultra-low energy (e.g., ~10+ year battery life), and deep coverage with the ability to reach difficult locations; (2) mission-critical control with strong security to protect sensitive personal, financial, and confidential information, ultra-high reliability (e.g., ~about 99.9999% reliability), ultra-low latency (e.g., ~about 1 millisecond (ms)), and users with widespread mobility or lack thereof; and (3) enhanced mobile broadband with very high capacity (e.g., ~about 10 Tbps / km^2), very high data rates (e.g., multi-Gbps rates, 100+ Mbps user experience rates), and deep awareness with advanced discovery and optimization.

[0030] Devices, networks, and systems may be configured to communicate over one or more portions 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 have been identified with frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although a portion of FR1 is higher than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers. Similar nomenclature issues may 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-300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" (mmWave) band.

[0031] With the above aspects in mind, it should be understood that unless otherwise specified, terms such as "sub-6 GHz," as used herein, may broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, it should be understood that unless otherwise specified, terms such as "mmWave," as used herein, may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

[0032] 5G NR devices, networks, and systems may be implemented to use optimized OFDM-based waveform features. These features may include advanced wireless technologies such as scalable numerology and transmission time intervals (TTIs), a common flexible framework for efficient multiplexing of services and features in dynamic low-latency time division duplex (TDD) or frequency division duplex (FDD) designs, massive multiple-input multiple-output (MIMO), robust mmWave transmissions, advanced channel coding, and device-centric mobility. The scalability of numerology in 5G NR, along with the scaling of subcarrier spacing, may efficiently address the operation of diverse services across diverse spectrums and diverse deployments. For example, in various outdoor and macro coverage deployments of FDD or TDD implementations below 3 GHz, subcarrier spacing may occur at 15 kHz, for example, over bandwidths of 1, 5, 10, 20 MHz, etc. For various other outdoor and small cell coverage deployments of TDD above 3 GHz, the subcarrier spacing may occur at 30 kHz over an 80 / 100 MHz bandwidth. For various other indoor wideband implementations using TDD in the unlicensed portion of the 5 GHz band, the subcarrier spacing may occur at 60 kHz over a 160 MHz bandwidth. Finally, for various deployments transmitting on a mmWave component at 28 GHz TDD, the subcarrier spacing may occur at 120 kHz over a 500 MHz bandwidth.

[0033] 5G NR's scalable numerology facilitates scalable TTIs for diverse latency and quality of service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmissions to start on symbol boundaries. 5G NR also contemplates a self-contained, unified subframe design with uplink or downlink scheduling information, data, and acknowledgments in the same subframe. The self-contained, unified subframe supports communication in unlicensed or contention-based shared spectrum, adaptive uplink or downlink that can be flexibly configured per cell to dynamically switch between uplink and downlink to meet current traffic needs.

[0034] For clarity, some aspects of the apparatus and techniques may be described below with respect to an example 5G NR implementation or in a 5G-centric manner, and 5G terminology may be used as an illustrative example in parts of the description below, however, the description is not intended to be limited to 5G applications.

[0035] It should further be understood that in operation, a wireless communications network adapted in accordance with the concepts herein may operate in any combination of licensed or unlicensed spectrum depending on loading and availability. Accordingly, it will be apparent to those skilled in the art that the systems, apparatus, and methods described herein may be applied to communications systems and applications other than the specific examples shown.

[0036] Although aspects and implementations are described in this application by illustrating some examples, those skilled in the art will understand that additional implementations and use cases may occur in many different configurations and scenarios. The innovations described herein may be implemented across many different platform types, devices, systems, shapes, 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 be specifically targeted to a use case or application, but a wide variety of applicability of the described innovations may occur. Implementations may range from chip-level or modular components to non-modular, non-chip-level implementations, and even aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more described aspects. In some practical settings, devices incorporating the described aspects and features may also necessarily include additional components and features in order to implement and practice the claimed and described aspects. It is contemplated that the innovations described herein may be practiced in a wide variety of implementations, including both large and small devices, chip-level components, multi-component systems (e.g., radio frequency (RF) chains, communication interfaces, processors), distributed configurations, end-user devices, and the like, of various sizes, shapes, and configurations.

[0037] 1 is a block diagram illustrating details of an exemplary wireless communication system according to one or more aspects. 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 appreciated by those skilled in the art, the components appearing in FIG. 1 likely have related counterparts including other network configurations, for example, cellular network configurations and non-cellular network configurations (e.g., device-to-device or peer-to-peer or ad-hoc network configurations, etc.).

[0038] The wireless network 100 shown in FIG. 1 includes several base stations 105 and other network entities. A base station may be a station that communicates with UEs and may also be referred to as an evolved Node B (eNB), next generation eNB (gNB), access point, etc. Each base station 105 may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a particular geographic coverage area of ​​a base station or base station subsystem serving the coverage area depending on the context in which the term is used. In implementations of the wireless network 100 herein, the base stations 105 may be associated with the same operator or different operators (e.g., the wireless network 100 may include a multi-operator wireless network). In addition, in implementations of the wireless network 100 herein, the base station 105 may provide wireless communications using one or more of the same frequencies as adjacent cells (e.g., one or more frequency bands in a licensed spectrum, an unlicensed spectrum, or a combination thereof). In some examples, an individual base station 105 or UE 115 may be operated by more than one network operating entity. In some other examples, each base station 105 and UE 115 may be operated by a single network operating entity.

[0039] A base station may provide communication coverage for a macro cell, or a small cell such as a pico cell or femto cell, or other type of cell. A macro cell generally covers a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with a service subscription with the network provider. A small cell such as a pico cell generally covers a relatively small geographic area and may allow unrestricted access by UEs with a service subscription with the network provider. A small cell such as a femto cell will also generally cover a relatively small geographic area (e.g., a home) and may provide unrestricted access as well as restricted access by UEs with an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in the home, etc.). A base station for a macro cell may be referred to as a macro base station. A base station for a small cell may be referred to as a small cell base station, a pico base station, a femto base station, or a home base station. In the example shown in FIG. 1, base stations 105d and 105e are regular macro base stations, while base stations 105a-105c are macro base stations enabled with one of three-dimensional (3D) MIMO, full dimension (FD) MIMO, or massive MIMO. Base stations 105a-105c take advantage of their higher-dimensional MIMO capabilities to leverage 3D beamforming in both advanced and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station that may be a home node or a portable access point. A base station may support one or multiple (e.g., two, three, four, etc.) cells.

[0040] The wireless network 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations may have similar frame timing and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, the base stations may have different frame timing 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 or asynchronous operation.

[0041] The UEs 115 are dispersed throughout the wireless network 100, and each UE may be fixed or mobile. Although mobile devices are generally referred to as UEs in standards and specifications promulgated by 3GPP, it should be understood that such devices may additionally or otherwise be referred to by those skilled in the art as mobile stations (MS), subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals (ATs), mobile terminals, wireless terminals, remote terminals, handsets, terminals, user agents, mobile clients, clients, gaming devices, augmented reality devices, vehicle components, vehicle devices, or vehicle modules, or some other suitable terminology. Within this document, a "mobile" device or UE does not necessarily have to be capable of movement and may be stationary. Some non-limiting examples of mobile devices that may have one or more implementations of UE 115 include mobile, cellular (cell) 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).The mobile device may also be an automobile or other transportation vehicle, a satellite radio, a global positioning system (GPS) device, a global navigation satellite system (GNSS) device, a logistics controller, a drone, a multicopter, a quadcopter, a smart energy or security device, an IoT or "Internet of Everything" (IoE) device such as a solar panel or solar array, city lighting, water infrastructure, other infrastructure, industrial automation and enterprise devices, eyewear, wearable cameras, smart watches, health or fitness trackers, mammalian implantable devices, gesture tracking devices, medical devices, consumer and wearable devices such as digital audio players (e.g., MP3 players), cameras, game consoles, and digital home or smart home devices such as home audio, video, multimedia devices, appliances, sensors, vending machines, intelligent lighting, home security systems, smart meters, etc. In one aspect, the UE may be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, the UE may be a device that does not include a UICC. In some aspects, a UE that does not include a UICC may be referred to as an IoE device. 1 are examples of mobile smartphone type devices accessing the wireless network 100. A UE may also be a machine specifically configured for connected communications, including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. The UEs 115e-115k shown in FIG. 1 are examples of various machines configured for communications accessing the wireless network 100.

[0042] A mobile device such as the UE 115 may be capable of communicating with any type of base station, such as a macro base station, a pico base station, a femto base station, a relay, etc. In FIG. 1, the communication links (represented as lightning bolts) indicate wireless transmissions between the UE and a serving base station, which is a base station designated to serve the UE on the downlink or uplink, or desired transmissions between base stations, as well as backhaul transmissions between base stations. The UE may act as a base station or other network node in some scenarios. Backhaul communication between base stations of the wireless network 100 may be performed using wired or wireless communication links.

[0043] In operation in the wireless network 100, the base stations 105a-105c serve the UEs 115a and 115b using coordinated spatial techniques such as 3D beamforming and coordinated multipoint (CoMP) or multi-connectivity. The macro base station 105d performs backhaul communications with the base stations 105a-105c and the small cell base station 105f. The macro base station 105d also transmits multicast services to which the UEs 115c and 115d subscribe and receive. Such multicast services may include mobile television or stream video, or other services for providing community information, such as weather emergencies or alerts such as amber or grey alerts.

[0044] The wireless network 100 of the implementation supports mission-critical communications with ultra-reliable and redundant links for mission-critical devices such as drone UE 115e. Redundant communication links with UE 115e include from macro base stations 105d and 105e and small cell base station 105f. Other machine-type devices such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device) can communicate through the wireless network 100 with base stations such as small cell base station 105f and macro base station 105e directly or by communicating with another user device that relays the information to the network in a multi-hop setting, such as UE 115f communicating temperature measurement information to smart meter UE 115g, which then reports the information to the network through small cell base station 105f. The wireless network 100 may also provide additional network efficiency through dynamic low latency TDD or low latency FDD communications, such as in a vehicle-to-vehicle (V2V) mesh network between the UEs 115i-115k communicating with the macro base station 105e.

[0045] In some aspects of the disclosure, the base station 105 of FIG. 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. To illustrate, in some examples, 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 described further below.

[0046] FIG. 2 is a block diagram illustrating an example of a base station 105 and a UE 115 according to one or more aspects. The base station 105 and the UE 115 may be any of the base stations and one of the UEs of FIG. 1. In the case of a restricted association scenario (as described above), the base station 105 may be the small cell base station 105f of FIG. 1, and the UE 115 may be the UE 115c or 115d operating in the coverage area of ​​the base station 105f, and the UE 115c or 115d will be included in a list of accessible UEs for the small cell base station 105f to access the small cell base station 105f. The base station 105 may also be some other type of base station. As shown in FIG. 2, the base station 105 may be equipped with antennas 234a-234t, and the UE 115 may be equipped with antennas 252a-252r to facilitate wireless communication.

[0047] In the base station 105, the transmit processor 220 may receive data from the data source 212 and control information from a processor 240, such as a processor. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid-ARQ (automatic repeat request) indicator channel (PHICH), a physical downlink control channel (PDCCH), an enhanced physical downlink control channel (EPDCCH), an MTC physical downlink control channel (MPDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. In addition, the transmit processor 220 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols, such as for a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), as well as a cell-specific reference signal. The transmit (TX) MIMO processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, or reference symbols, if applicable, and may provide output symbol streams to modulators (MODs) 232a-t. For example, the spatial processing performed on the data symbols, control symbols, or reference symbols may include precoding. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators 232a-t may be transmitted via the antennas 234a-t, respectively.

[0048] At the UE 115, the antennas 252a-252r may receive downlink signals from the base station 105 and may provide received signals to demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain the received symbols from the demodulators 254a-254r, perform MIMO detection on the received symbols, if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols and provide decoded data for the UE 115 to a data sink 260 and provide decoded control information to a processor 280, such as a processor.

[0049] On the uplink, at the UE 115, a transmit processor 264 may receive and process data (e.g., for the Physical Uplink Shared Channel (PUSCH)) from a data source 262 and control information (e.g., for the Physical Uplink Control Channel (PUCCH)) from a processor 280. In addition, the transmit processor 264 may also generate reference symbols for a reference signal. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a-254r (e.g., for SC-FDM, etc.), and transmitted to the base station 105. At the base station 105, uplink signals from the UE 115 may be received by antennas 234, processed by demodulator 232, detected by a MIMO detector 236 if applicable, and further processed by receive processor 238 to obtain decoded data and control information sent by the UE 115. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a processor 240 .

[0050] Processors 240 and 280 may direct operation at base station 105 and UE 115, respectively. Processor 240 or other processors and modules at base station 105, or processor 280 or other processors and modules at UE 115, may perform or direct the execution of various processes for the techniques described herein, such as for performing or directing other processes, such as transmitting and receiving FH indicator 150, for the techniques described herein, such as the execution shown in FIG. 8-FIG. 11, or the techniques described herein. Memory 242 and memory 282 may store data and program codes for base station 105 and UE 115, respectively. Scheduler 244 may schedule UEs for data transmission on the downlink or uplink.

[0051] In some cases, the UE 115 and the base station 105 may operate in a shared radio frequency spectrum band, which may include licensed or unlicensed (e.g., contention-based) frequency spectrum. In the unlicensed frequency portion of the shared radio frequency spectrum band, the UE 115 or the base station 105 may conventionally perform a medium sensing procedure to compete for access to the frequency spectrum. For example, the UE 115 or the base station 105 may perform a listen-before-talk (LBT) or listen-before-transmitting (LBT) procedure, such as a clear channel assessment (CCA), before communicating to determine if a shared channel is available. In some implementations, the CCA may include an energy detection procedure to determine if there are any other active transmissions. For example, the device may infer that a change in a received signal strength indicator (RSSI) of a power meter indicates that the channel is occupied. In particular, a signal power concentrated within some bandwidth and exceeding a predefined noise floor may indicate another wireless transmitter. CCA may also include detection of certain sequences indicative of channel usage. For example, another device may transmit a certain preamble before transmitting a data sequence. In some cases, the LBT procedure may include a wireless node adjusting its own backoff window based on the amount of energy detected on the channel or acknowledgment / negative acknowledgment (ACK / NACK) feedback for its own transmitted packets as a proxy for collisions.

[0052] 3 is a block diagram illustrating an example of a wireless communication system 300 in accordance with certain aspects of the present disclosure. The wireless communication system 300 may include one or more base stations, such as the base station 105. The wireless communication system 300 may further include one or more UEs, such as a UE 115x, a UE 115y, and a UE 115z. In some examples, the UEs 115x-z correspond to the UEs 115 shown in FIG.

[0053] The example of Figure 3 illustrates that the base station 105 may include one or more processors (such as the processor 240) and may include a memory 242. The base station 105 may further include a transmitter 306 and a receiver 308. The processor 240 may be coupled to the memory 242, the transmitter 306, and the receiver 308. In some examples, the transmitter 306 and the receiver 308 include one or more components described with reference to Figure 2, such as one or more of the modulator / demodulator 232a-t, the MIMO detector 236, the receive processor 238, the transmit processor 220, or the TX MIMO processor 230. In some implementations, the transmitter 306 and the 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 the UEs 115x-z, and the receiver 308 may be configured to receive signaling, control information, and data from the UEs 115x-z.

[0055] Each UE 115x-z may include one or more processors (such as processor 280), a memory (such as memory 282), a transmitter (such as transmitter 356), and a receiver (such as receiver 358). The processor 280 may be coupled to the memory 282, the transmitter 356, and the receiver 358. In some examples, the transmitter 356 and the receiver 358 may include one or more components described with reference to FIG. 2, such as one or more of the modulator / demodulator 254a-r, the MIMO detector 256, the receive processor 258, the transmit processor 264, or the TX MIMO processor 266. In some implementations, the transmitter 356 and the receiver 358 may be integrated into one or more transceivers of the UE 115.

[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, the receiver 308, the transmitter 356, or the receiver 358 may include an antenna array. The antenna array may include multiple antenna elements that perform wireless communication with other devices. In some implementations, the antenna array may perform wireless communication using different beams, also referred to as antenna beams. The beams may include transmit beams and receive beams. By way of example, the antenna array may include multiple independent sets (or subsets) of antenna elements (or multiple individual antenna arrays), where each set of antenna elements of the antenna array may be configured to communicate using a different respective beam that may have a different respective direction from the other beams. For example, a first set of antenna elements of the antenna array may be configured to communicate via a first beam having a first direction, and a second set of antenna elements of the antenna array may be configured to communicate via a second beam having a second direction. In other implementations, the antenna array may be configured to communicate via more than two beams. In some implementations, one or more sets of antenna elements of the 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 2 antenna elements, 4 antenna elements, 10 antenna elements, 20 antenna elements, or any other number of antenna elements greater than 2. Although described as an antenna array, in other implementations the antenna array may include or correspond to multiple antenna panels, each of which may be configured to communicate using a different respective 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 a plurality of 5G-capable UEs 115 and a plurality of 5G-capable 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 UEs 115 may be associated with a particular capability type. In some examples, UEs 115x and 115z are associated with a first capability type and UE 115y is associated with a second capability type different from the first capability type. In some implementations, the first capability type may correspond to a “reduced capability” (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-reliable low latency communications (URLLC) capability type, or another capability type. In some examples, UEs 115x and UEs 115z may correspond to a wearable device, a medical monitoring device, a sensor device, an Internet of Things (IoT) device, or a smart city device (such as a surveillance camera), as illustrative examples.

[0060] To further illustrate, in some implementations, the UE 115x, the UE 115y, and the UE 115z may communicate with the base station 105 using a first uplink bandwidth portion (BWP) 362 (e.g., a default uplink BWP of the UE 115x), 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 include less bandwidth than the second uplink BWP 372 (e.g., to reduce power consumption associated with the UE 115x and the UE 115z). Each of the uplink BWPs 362, 372, and 382 may correspond to an initial uplink BWP or an active uplink BWP. To illustrate, the first uplink BWP 362 may correspond to an initial uplink BWP used by the UE 115x prior to establishing a radio resource control (RRC) connection between the base station 105 and the UE 115x. In some other examples, the first uplink BWP 362 may correspond to an active uplink BWP configured by the base station 105 after establishing an RRC connection between the base station 105 and the UE 115x.

[0061] In operation, the transmitter 356 may operate based on the first uplink BWP 362. For example, the transmitter 356 may be configured to transmit an uplink control channel transmission 330 within the first uplink BWP 362 to the base station 105 (e.g., the uplink control channel transmission 330 is transmitted using 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 transmissions 330 based on an FH mode 360. During operation based on the FH mode 360, the transmitter 356 may change (or “hop”) between transmitting using a first frequency subset 364 of a first uplink BWP 362 and transmitting using a second frequency subset 366 of the first uplink BWP 362. In some circumstances, performing uplink control channel transmissions 330 based on the FH mode 360 ​​may be associated with reduced performance of one or more other UEs 115, such as resource fragmentation.

[0063] To illustrate, FIG. 4 illustrates an example of a resource allocation scheme 400 according to some aspects of the disclosure. In the example resource allocation scheme 400, the first uplink BWP 362 is smaller than the second uplink BWP 372 (e.g., includes a smaller frequency range than the second uplink BWP 372). During operation of the transmitter 356 based on the 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 the FH mode 360, the frequencies corresponding to the first frequency subset 364 and the second frequency subset 366 may be unavailable (or unassigned) to the UE 115y. As a result, the resources of the second uplink BWP 372 may be separated (or fragmented) into three non-contiguous frequency ranges.

[0064] In some aspects of the disclosure, the base station 105 may transmit the FH indicator 150 to selectively enable or disable the FH mode 360. Disabling the FH mode 360 ​​may reduce or avoid resource fragmentation of the second uplink BWP 372. For example, when the FH mode 360 ​​is disabled, the UE 115x may perform 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 further illustrate, and referring again to FIG. 3 , the base station 105 may transmit one or more messages 320 including the FH indicator 150 to the UE 115x. In some examples, the UE 115x transmits a message 310 indicating the capability type 314 of the UE 115x to the base station 105, and the base station 105 transmits the FH indicator 150 to the UE 115x based on the capability type 314. In some examples, the capability type 314 indicates that the UE 115x corresponds to a RedCap UE. In such examples, the 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, the capability type 314 may indicate one or more other parameters, such as one or more of a bandwidth or a center frequency of the first uplink BWP 362, as illustrative examples.

[0066] In some examples, the message 310 corresponds to a type 1 message (msg1) associated with a four-step random access channel (RACH) procedure 342 (e.g., a contention-based RACH procedure) indicating a capability type 314. In some such examples, the one or more messages 320 may include or correspond to one of a type 4 message (msg4) associated with the four-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 association with a 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 combined processing of the downlink control channel transmission and the downlink data channel transmission to identify the FH indicator 150, which may improve the reliability of the transmission of the FH indicator 150 in some circumstances.

[0067] In some other examples, the message 310 corresponds to a type 3 message (msg3) associated with a four-step RACH procedure 342 and having one of a demodulation reference signal (DMRS) configuration indicating the capability type 314, a payload indicating the capability type 314, or a scrambling identifier indicating the capability type 314. In some such examples, the one or more messages 320 may include or correspond to one of a message 4 (msg4) associated with the four-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, the message 310 corresponds to a type A message (msgA) associated with a two-step RACH procedure 344 (e.g., a contention-free RACH procedure) and having one of a preamble indicating the capability type 314, a DMRS configuration indicating the capability type 314, a payload indicating the capability type 314, or a scrambling identifier for a payload indicating the capability type 314. In some such examples, the one or more messages 320 may include or correspond to one of a type B message (msgB) associated with the two-step RACH procedure 344, a downlink control channel message scheduling msgB, or a combination of a downlink control channel transmission and a downlink data channel transmission.

[0069] To further illustrate, in one example of a four-step RACH procedure 342, the UE 115x may transmit msg1 to indicate a random access preamble selected by the UE 115x, and the base station 105 may transmit msg2 to indicate a response to the random access preamble, including an uplink resource allocation. The UE 115x may transmit msg3 to the base station 105 using the uplink resource allocation, and the base station 105 may transmit a contention resolution message to the UE 115x via msg4. In one example of a two-step RACH procedure 344, the base station 105 may assign a random access preamble to the UE 115x and indicate the assigned random access preamble to the UE 115x. The UE 115x may transmit the assigned random access preamble to the base station 105 via msgA, and the base station 105 may transmit a random access response to msgA to the UE 115x via msgB.

[0070] In some other examples, the one or more messages 320 may include or correspond to another message transmitted regardless of the RACH type associated with the UE 115x. For example, the one or more messages 320 may include or correspond to a system information (SI) message associated with the base station 105. In some examples, the base station 105 transmits the SI message using a broadcast technique that may enable reception of the SI message by multiple UEs (such as UEs 115x-z).

[0071] The FH indicator 150 may include a bit 324 having a value indicating whether the FH mode 360 ​​is enabled or disabled. To illustrate, the bit 324 may indicate a first value, and the transmitter 356 may perform the uplink control channel transmission 330 using the FH mode 360 ​​based on the first value of the bit 324. In some other examples, the bit 324 may indicate a second value different from the first value, and the transmitter may disable the FH mode 360 ​​for the uplink control channel transmission 330 based on the second value of the 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 indicating a resource set 346 in the first uplink BWP 362. For example, the memory 282 may store a table of resource sets, and the first group of one or more bits 326 may correspond to an index to 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 the 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 included in the first uplink BWP 362.

[0073] In some examples, at least a subset of resource set 346 may be shared or overlap with at least one other resource set of at least one other device having the same or different capability type as UE 115x. For example, resource set 346 may include at least one common resource as resource set 374 of UE 115y, which may have a different capability type than UE 115x. As another example, resource set 346 may include at least one common resource as resource set 384 of UE 115z, which may have the same capability type as UE 115x. In some examples, resource set 374 may correspond to an initial uplink BWP or an active uplink BWP of UE 115y, and resource set 384 may correspond to an initial uplink BWP or an active uplink BWP of UE 115z.

[0074] In some other examples, resource set 346 is distinct from one or more other resource sets of at least one other device having the same or different capability type as UE 115x. For example, resource set 346 may be distinct from resource set 374 of UE 115y (and may not include at least one common resource), where UE 115y may have a different capability type than UE 115x. As another example, resource set 346 may be distinct from resource set 384 of UE 115z, where UE 115z may have the same capability type as UE 115x.

[0075] Alternatively or additionally, the FH indicator 150 may optionally include a second group 328 of one or more bits indicating a repetition number 348, and the transmitter 356 may perform one or more repetitions 332 of the uplink control channel transmission 330 based on the repetition number 348. In some examples, performing one or more repetitions 332 may improve reliability associated with the uplink control channel transmission 330. By way of illustration, disabling the FH mode 360 ​​may reduce a frequency diversity gain associated with the uplink control channel transmission 330, and performing one or more repetitions 332 may compensate for the reduced frequency diversity gain (e.g., by increasing a time diversity gain associated with the uplink control channel transmission 330).

[0076] In some examples, the base station 105 transmits the one or more messages 320 using a broadcast transmission technique. Depending on the particular example, the base station 105 may transmit the one or more messages 320 (e.g., using a broadcast transmission technique) before or after an initial access procedure by the UE 115x. The initial access procedure may include establishing an RRC connection between the base station 105 and the UE 115. In some other examples, the base station 105 transmits the one or more messages 320 using a unicast transmission technique. Depending on the particular example, the base station 105 may transmit the one or more messages 320 using a unicast transmission technique and using one of an RRC connection or media access control (MAC) control element (MAC-CE) signaling.

[0077] While some examples of the uplink control channel transmission 330 may be described as a single signal or a single transmission, in some other examples, the uplink control channel transmission 330 may include multiple uplink signals within the first uplink BWP 362. In such examples, the bits of the UCI 334 may be allocated (or "shared") among the multiple uplink signals within the first uplink BWP 362. Additionally, the FH indicator 150 may be shared among the multiple uplink signals (e.g., by enabling or disabling the FH mode 360 ​​for each of the multiple uplink signals based on the value of the bit 324). In some examples, the multiple uplink signals include one or more of 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, as illustrative examples.

[0078] 5 is a diagram illustrating an example of a first uplink BWP 362, a second uplink BWP 372, and a third uplink BWP 382, ​​according to some aspects of the disclosure. FIG 5 illustrates 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] Aligning the first boundary 502 of the second uplink BWP 372 with the first frequency subset 364 may reduce or avoid resource fragmentation of the second uplink BWP 372 during operation of the transmitter 356 based on the FH mode 360. For example, if resources of the first frequency subset 364 are unavailable to the UE 115y during uplink control channel transmission 330, a contiguous group 504 of resources may be available to the UE 115y (e.g., rather than multiple non-contiguous groups of resources that may result from resource fragmentation). In some examples, by reducing or avoiding resource fragmentation (e.g., by allowing data to be transmitted in a single packet using the contiguous group 504 of resources instead of using multiple packets using multiple non-contiguous groups of resources), the number of packets transmitted by the UE 115y may be reduced. As a result, data throughput and performance may be improved.

[0080] 5 also illustrates that the first frequency subset 364 may be aligned with a third frequency subset 506 of a third uplink BWP 382 associated with a third device (e.g., UE 115z). As a result, resource fragmentation for the second uplink BWP 372 due to transmissions by UE 115z using the third frequency subset 506 may be reduced or avoided.

[0081] 6 is a diagram illustrating an additional example of the first uplink BWP 362, the second uplink BWP 372, and the third uplink BWP 382 according to some aspects of the disclosure. FIG. 6 illustrates 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., UE 115z). In some implementations, the example of FIG. 6 may reduce interference between the transmissions of UE 115x and UE 115y (due to the use of different frequency subsets 364, 606 for transmission), while also enabling a contiguous group of resources 604 for UE 115y, thus reducing or avoiding resource fragmentation for UE 115y.

[0082] 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 UEs of the wireless communication system 300, such as the UEs 115x-z. As an illustrative example, when 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 disabling of the FH mode 360 ​​and may optionally indicate use of resources of the second frequency subset 366 via the first group of one or more bits 326. Alternatively or additionally, the base station 105 may perform alignment of the uplink BWP based on the resource allocation 302, such as by aligning the frequency subsets 364, 506 with the first boundary 502, or by aligning the first frequency subset 364 with the first boundary 502 and aligning the fourth frequency subset 606 with the second boundary 602.

[0083] Although certain examples have been described with reference to an explicit FH indication technique (such as using bit 324), in some other examples, UE 115 may determine whether FH should be performed according to an implicit FH indication technique. An implicit FH indication technique may be used instead of or in addition to an explicit FH indication technique. For example, in some implementations, if UE 115x does not receive an explicit indication of FH indicator 150 from base station 105, UE 115x may determine whether to enable or disable FH mode 360 ​​using an implicit FH indication technique. Examples of implicit FH indication techniques are further described with reference to FIG. 7.

[0084] 7 is a block diagram illustrating another example of a wireless communication system 700 in accordance with certain aspects of the present disclosure. The wireless communication system 700 may include one or more base stations, such as the base station 105. The wireless communication system 300 may further include one or more UEs, such as a UE 115x, a UE 115y, and a UE 115z.

[0085] During operation, the base station 105 may transmit an indication of a bandwidth 712 associated with the base station 105, such as a serving cell system bandwidth associated with the base station 105. In some examples, the base station 105 may transmit a system information (SI) message 710 that includes a first indication of the bandwidth 712. The base station 105 may transmit the first indication of the bandwidth 712 using broadcast transmission techniques.

[0086] One or more of UEs 115x-z may receive the first indication of the bandwidth 712 and may decode the first indication to identify the bandwidth 712. For example, UE 115x may receive the SI message 710 and may decode the SI message 710 to identify the bandwidth 712.

[0087] The base station 105 may transmit a second indication of the first uplink BWP 362 associated with the UE 115x. In some examples, the second indication of 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 indication of the first uplink BWP 362 is included in an RRC configuration message 720 sent by the base station 105 to the UE 115x 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 indication of the first uplink BWP 362 may be included in another message. Depending on the particular example, the first uplink BWP 362 may correspond to an initial BWP of the UE 115x or an active BWP of the UE 115x.

[0088] In some aspects of the disclosure, the UE 115x may determine whether the first uplink BWP 362 exceeds a threshold 750. For example, the processor 280 may compare a first number of Hertz (Hz) corresponding to the first uplink BWP 362 to a second number of Hz corresponding to the threshold 750 to determine whether the first uplink BWP 362 exceeds the threshold 750. The threshold 750 may be based at least in part on the bandwidth 712.

[0089] The UE 115x may enable (or disable) the FH mode 360 ​​based on whether the first uplink BWP 362 exceeds (or does not exceed) the threshold 750. To illustrate, in some examples, the processor 280 may determine that the first uplink BWP 362 exceeds the threshold 750. In such examples, the processor 280 may enable the FH mode 360 ​​and the transmitter 356 may perform the uplink control channel transmission 330 based on the FH mode 360. In some other examples, the processor 280 may determine that the first uplink BWP 362 does not exceed the threshold 750. In such examples, the processor 280 may disable the FH mode 360 ​​and the transmitter 356 may perform the uplink control channel transmission 330 without using the FH mode 360.

[0090] In some implementations, the threshold 750 is based on the bandwidth 712 and the parameter 752 (e.g., a coefficient having a positive or non-negative value). In some examples, the threshold 750 corresponds to a product of the bandwidth 712 and the parameter 752. In some implementations, the parameter 752 is determined by a network device (e.g., base station 105) and indicated to the UE 115x in system information (e.g., via SI message 710) or using RRC signaling (e.g., via RRC configuration message 720 or via another message). In some other examples, the base station 105 and the UE 115x operate according to a wireless communication protocol (such as a 5G NR wireless communication protocol), and the wireless communication protocol specifies the parameter 752 based on one or more of the bandwidth 712, a maximum bandwidth associated with the device type (e.g., a maximum bandwidth supported by the capability type 314 of FIG. 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). As a non-limiting illustrative example, the first frequency subset 364 may include a contiguous group of two contiguous PRBs, and the second frequency subset 366 may include a contiguous group of three contiguous PRBs.

[0092] In some examples, one or more of the first frequency subset 364 or the second frequency subset 366 spans either a second contiguous group of symbols in a slot or a third contiguous group of symbols in multiple slots. By way of illustration, if one or more of the first frequency subset 364 or the second frequency subset 366 spans contiguous groups of symbols in a slot, the FH mode 360 ​​may correspond to or be referred to as an intra-slot frequency hopping mode. If one or more of the first frequency subset 364 or the second frequency subset 366 spans contiguous groups of symbols in multiple slots, the FH mode 360 ​​may correspond to or be referred to as 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 the FH mode 360 ​​is enabled for the uplink control channel transmission 330 in the first uplink BWP 362, the PRBs of the first frequency subset 364 may not overlap with (and may not be included in) the PRBs of the second frequency subset 366.

[0094] One or more examples described herein may improve the performance of one or more UEs, such as the UE 115y. For example, by disabling the FH mode 360 ​​in one or more cases where the first uplink BWP 362 is included in the second uplink BWP 372, resource fragmentation associated with the second uplink BWP 372 may be reduced or avoided. As a result, the number of packets used by the UE 115y to transmit data to the base station 105 may be reduced, which may reduce latency in some circumstances.

[0095] 8 is a flow chart illustrating an example of a method 800 of wireless communication performed by a UE, in accordance with some aspects. In some examples, the method 800 is performed by the UE 115.

[0096] The method 800 includes, at 802, receiving one or more messages from a base station 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 that includes a first frequency subset and a second frequency subset. For example, the UE 115x may receive (e.g., using the receiver 358) an FH indicator 150 that indicates whether an FH mode 360 ​​is enabled or disabled for the UE 115x.

[0097] The method 800 further includes, at 804, transmitting an uplink control channel transmission to the base station. The uplink control channel transmission is transmitted using both the first and second frequency subsets based on the frequency hopping indicator specifying that the frequency hopping mode is enabled, or using one of the first or second frequency subsets based on the frequency hopping indicator specifying that the frequency hopping mode is disabled. For example, based on the FH indicator 150 indicating that the FH mode 360 ​​is enabled, the UE 115x may perform the uplink control channel transmission 330 (e.g., using the transmitter 356) using both the first and second frequency subsets 364 and 366, such as by changing (or “hopping”) between transmitting using the first and second frequency subsets 364 and 366. In some other examples, based on the FH indicator 150 indicating that the FH mode 360 ​​is disabled, the UE 115x may perform the uplink control channel transmission 330 (e.g., using the transmitter 356) using one of the first frequency subset 364 or the second frequency subset 366 (but not both).

[0098] 9 is a flow chart illustrating an example of a method 900 of wireless communication performed by a base station, in accordance with some aspects. In some examples, the method 900 is performed by a base station 105.

[0099] The method 900 includes, at 902, transmitting, to a 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 that includes a first frequency subset and a second frequency subset. For example, the base station 105 may transmit (e.g., using the transmitter 306) an FH indicator 150 that indicates whether an FH mode 360 ​​is enabled or disabled for the UE 115x.

[0100] The method 900 further includes receiving, at 904, 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 specifying that the frequency hopping mode is enabled, or using one of the first or second frequency subsets based on the frequency hopping indicator specifying that the frequency hopping mode is disabled. For example, based on the FH indicator 150 indicating that the FH mode 360 ​​is enabled, the base station 105 may receive the uplink control channel transmission 330 (e.g., using the receiver 308) using both the first and second frequency subsets 364 and 366, such as 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 the FH mode 360 ​​is disabled, the base station 105 may receive the uplink control channel transmission 330 (e.g., using the receiver 308) using one (but not both) of the first frequency subset 364 or the second frequency subset 366.

[0101] 10 is a flow chart illustrating an example of a method 1000 of wireless communication performed by a UE, in accordance with some aspects. In some examples, the method 1000 is performed by the UE 115.

[0102] The method 1000 involves, at 1002, receiving a first indication of a bandwidth associated with the base station from a base station.

[0103] The method 1000 further includes receiving, from the base station, a second indication of the first uplink BWP, at 1004. The first uplink BWP includes the first frequency subset and further includes a second frequency subset.

[0104] The method 1000 further includes, at 1006, transmitting an uplink signal transmission to the base station. The uplink signal transmission is transmitted using both the first and second frequency subsets based on the first uplink BWP exceeding a threshold based at least in part on a bandwidth associated with the base station, or using one of the first or second frequency subsets based on the first uplink BWP not exceeding a threshold.

[0105] 11 is a flow chart illustrating an example of a method 1100 of wireless communication performed by a base station, in accordance with some aspects. In some examples, the method 1100 is performed by a base station 105.

[0106] The method 1100 includes, at 1102, transmitting to a UE a first indication of a bandwidth associated with a base station.

[0107] The method 1100 further includes transmitting a second indication of the first uplink BWP to the UE, at 1104. The first uplink BWP includes the first frequency subset and further includes a second frequency subset.

[0108] The method 1100 further includes receiving, at 1106, an uplink signal transmission from the UE. The uplink signal transmission is received using both the first frequency subset and the second frequency subset based on the first uplink BWP exceeding a threshold based at least in part on a 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 a threshold.

[0109] 12 is a block diagram illustrating an example of a UE 115 according to some aspects of the disclosure. The UE 115 may include the structure, hardware, or components illustrated in FIG. 2. For example, the UE 115 may include a processor 280 that may execute instructions stored in a memory 282. Using the processor 280, the UE 115 may transmit and receive signals via the wireless radios 1210a-r and antennas 252a-r. The wireless radios 1201a-r may include one or more components or devices described herein, such as one or more of the modulators / demodulators 254a-r, MIMO detectors 256, receive processor 258, transmit processor 264, TX MIMO processor 266, transmitter 356, receiver 358, or one or more other components or devices.

[0110] In some implementations, the memory 282 may store FH mode determination instructions 1202 executable by the processor 280 to identify whether to enable or disable the FH mode 360 ​​(e.g., based on the value of the bit 324 of the FH indicator 150). The memory 282 may store FH transmission instructions 1204 executable by the processor 280 to perform the uplink control channel transmission 330 using the FH mode 360 ​​based on the FH indicator 150 specifying that the FH mode 360 ​​should be enabled. The memory 282 may store non-FH transmission instructions 1206 executable by the processor 280 to perform the uplink control channel transmission 330 without using the FH mode 360 ​​based on the FH indicator 150 specifying that the FH mode 360 ​​should be disabled.

[0111] 13 is a block diagram illustrating an example of a base station 105 according to some aspects of the disclosure. The base station 105 may include the structure, hardware, and components illustrated in FIG. 2. For example, the base station 105 may include a processor 240 that may execute instructions stored in a 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 one or more of the modulator / demodulators 232a-t, the MIMO detector 236, the receive processor 238, the transmit processor 220, the TX MIMO processor 230, the transmitter 306, the receiver 308, or one or more other components or devices.

[0112] In some implementations, the memory 242 may store FH mode determination instructions 1302 executable by the processor 240 to select whether to enable or disable the FH mode 360 ​​(e.g., by setting a value of the bit 324 of the FH indicator 150, which may be based on the resource allocation 302). The memory 242 may store FH reception instructions 1304 executable by the processor 240 in response to the FH indicator 150 specifying that the FH mode 360 ​​should be enabled, to receive uplink control channel transmissions 330 based on the FH mode 360. The memory 242 may store non-FH reception instructions 1306 executable by the processor 240 in response to the FH indicator 150 specifying that the FH mode 360 ​​should be disabled, to receive uplink control channel transmissions 330 without using the FH mode 360.
