These networks can be multiplexed networks, supporting communication for multiple users by sharing available network resources.

A wireless communication network may include a number of components. These components may include wireless communication devices (such as base stations (or Node Bs)) capable of supporting communication for multiple user equipments (UEs). A UE can communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from base stations to UEs, and the uplink (or reverse link) refers to the communication link from UEs to base stations.

The base station can transmit data and control information to the UE on the downlink, or receive data and control information from the UE on the uplink. On the downlink, transmissions from a base station may experience interference from transmissions from neighboring base stations or from other wireless radio frequency (RF) transmitters. On the uplink, transmissions from UEs may encounter interference from other UEs communicating with neighbor base stations or from uplink transmissions from other wireless RF transmitters. Such interference can degrade performance on both the downlink and uplink.

As demand for mobile broadband access continues to increase, the more UEs accessing long-range wireless communication networks, the more short-range wireless systems are deployed in cells, and the possibility of network interference and congestion increases.

Although aspects and implementations have been described in this case by way of illustration of some examples, those of ordinary skill in the art to which this invention pertains will appreciate that additional implementations and use cases can be realized in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, packaging arrangements. For example, aspects and/or uses may be implemented via integrated chip implementations and other non-modular component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail/purchasing devices, medical devices) , devices supporting artificial intelligence (AI), etc.). Various applicability of the described innovations may arise, although some examples may or may not be specific to a use case or application. Implementations can range from wafer-level or modular components to non-modular, non-wafer-level implementations, and can also be aggregated, distributed, or original equipment manufacturing that incorporates one or more aspects of the described innovations manufacturer (OEM) equipment or systems. In some practical setups, devices incorporating the described aspects and features may also have to include other components and features in order to realize and practice the claimed and described aspects. For example, the transmission and reception of wireless signals must include multiple components for both analog and digital purposes (e.g., including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders /accumulator, etc.). The innovations described herein can be practiced in a wide variety of devices, wafer-level components, systems, distributed arrangements, end-user devices, etc., having different sizes, shapes, and configurations.

Wireless communication systems increasingly support different types of devices with different capabilities. For example, the wireless communication system may include one or more user equipments (UEs) of a first capability type, and may also 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, RedCap devices can reduce cost, reduce device size, or reduce 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 communication (URLLC) capability type, or other capability types.

In some circumstances, 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 signals using a frequency within a first uplink bandwidth part (BWP) associated with the RedCap UE. In some cases, the first uplink BWP may overlap with a second uplink BWP associated with another UE (e.g., non-RedCap UE) (e.g., the first uplink BWP may be the second uplink BWP a subset of BWP). Therefore, the frequencies used by RedCap UEs may not be available to non-RedCap UEs.

In some instances, the non-RedCap second uplink BWP may experience resource fragmentation due to frequency usage by RedCap UEs. 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 segmented into three discontinuous frequency regions. In some implementations, transmissions by the RedCap UE using these three non-segmented frequency regions may involve three different packets (eg, instead of a single packet that may be transmitted using a single contiguous non-segmented frequency region). As a result, latency associated with non-RedCap UEs may be increased, which may be undesirable in certain applications (eg, in the case of certain eMBB or URLLC applications).

In some aspects of this disclosure, a 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, 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, resource fragmentation for the second uplink BWP associated with the second UE may be reduced in some instances. In some implementations, the subset of frequencies can be aligned with the frequency boundaries of the second uplink BWP to further reduce or avoid resource fragmentation for the second uplink BWP.

Depending on the particular instance, enabling or disabling frequency hopping may be performed using explicit or implicit techniques. In an example of an explicit technique, the base station may send a frequency hopping indicator that specifies whether frequency hopping is enabled or disabled for the UE. In some implementations, the base station may send the frequency hopping indicator based on the UE's capability type (eg, an indication that the UE is associated with a RedCap capability type). For purposes of illustration, the UE may respond in a message associated with a random access channel (RACH) procedure (e.g., a type one message (msg1) for a four-step RACH procedure, a type three message (msg3) for a four-step RACH procedure, or two In the Type A message (msgA) of the RACH procedure), the capability type is indicated. As an illustrative example, a base station may include a type two message (msg2) or a type four message (msg4) for a four-step RACH procedure, a message for scheduling msg2 or msg4, a type B message (msgB) for a two-step RACH procedure, The frequency hopping indicator is included in the message for scheduling msgB, or the combination of the downlink channel and the control channel.

In an implicit technique, the UE may compare a first uplink BWP associated with the UE to a threshold, where the threshold is 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 transmission. If the first uplink BWP fails to 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 the specified value. As an illustrative example, the specific value may be specified by the base station, or may be specified by a wireless communication protocol.

By selectively disabling frequency hopping, the performance of one or more UEs can be improved. For example, by disabling frequency hopping in one or more cases where the first uplink BWP of a RedCap UE is included in the second uplink BWP of a non-RedCap UE, correlation with the second uplink BWP can be reduced or avoided Linked resource segments. As a result, the number of packets used by non-RedCap UEs to send data can be reduced, which in some cases can reduce latency.

For further illustration, in various implementations, one or more aspects described herein can be used in wireless communication networks such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA ) network, frequency division multiple access (FDMA) network, orthogonal FDMA (OFDMA) network, single carrier FDMA (SC-FDMA) network, LTE network, GSM network, fifth generation (5G) Or New Radio (NR) networks (sometimes referred to as "5G NR" networks, systems or devices) and other communications networks. As described herein, the terms "network" and "system" are often used interchangeably.

For example, a CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, and so on. UTRA includes Wideband CDMA (W-CDMA) and Low Code Rate (LCR). CDMA 2000 covers IS-2000, IS-95 and IS-856 standards.

A TDMA network may, for example, implement a radio technology such as the 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 known as GERAN. GERAN is the radio subgroup component of GSM/EDGE, and the network that connects base stations (eg, Ater and Abis interfaces) and base station controllers (A interface, etc.). The radio access network represents the component of the GSM network through which telephone calls and packet data are communicated between the public switched telephone network (PSTN) and the Internet and user handsets (also known as user terminals or user terminals) Or equipment (UE)) between routing. The mobile phone service provider's network may include one or more GERANs, which may be coupled with UTRAN in the case of UMTS/GSM networks. In addition, the service provider network may also include one or more LTE networks or one or more other networks. Various network types may use different radio access technologies (RATs) and RANs.

An OFDMA network 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, and others. UTRA, E-UTRA and GSM are part of the Universal Mobile Telecommunications System (UMTS). Specifically, Long Term Evolution (LTE) is a version of UMTS that employs E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents provided by an organization named "3rd Generation Partnership Project" (3GPP), and in documents from an organization named "3rd Generation Partnership Project 2 cdma2000 is described in the document of the organization "(3GPP2). These various radio technologies and standards are known or are about to be developed. For example, 3GPP is aimed at harmonization among groups of telecommunications unions specifying 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 the next generation of mobile networks, mobile systems and mobile devices. This disclosure may describe certain aspects with reference to LTE, 4G, or 5G NR technologies; however, this description is not intended to be limited to a particular technology or application, and one or more aspects described with reference to a technology should be understood to apply to Another technique. Additionally, one or more of the subject matter may relate to shared access to the wireless spectrum between networks using different radio access technologies or radio air interfaces.

5G networks consider various deployments, various spectrums, and various services and devices that can be realized using a unified OFDM-based air interface. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further enhancements to LTE and LTE-A are also considered. 5G NR will be able to scale to provide the following coverage: (1) coverage with ultra-high density (e.g. ~1M nodes/km^2), ultra-low complexity (e.g. ~10s bits/s), ultra-low energy ( For example, about 10+ years of battery life) of very large Internet of Things (IoT) and deep coverage with the ability to reach challenging locations; (2) including mission-critical controls with strong security to protect sensitive individuals, financial or confidential information, ultra-high reliability (eg, approximately 99.9999 percent reliability), ultra-low latency (eg, approximately 1 millisecond (ms)), and users with a wide range of mobility or lack of mobility; (3 ) with enhanced mobile broadband, including extremely high capacity (e.g., approximately 10 Tbps/km^2), extreme data rates (e.g., multi-Gbps rates, user experience rates above 100+ Mbps), and with improved discovery and optimized depth perception.

Devices, networks and systems may be configured to communicate over one or more portions of the electromagnetic spectrum. The electromagnetic spectrum is usually subdivided based on frequency (or wavelength) into various categories, frequency bands, channels, etc. In 5G NR, two initial operating frequency bands are determined as frequency range names FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. In various documents and articles, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band, despite the portion of FR1 that is greater than 6 GHz. Similar nomenclature issues sometimes arise with FR2, which is often (interchangeably) referred to as the "millimeter wave" (mmWave) band in various documents and articles, although it is identified with the International Telecommunication Union (ITU) as "mmWave" The frequency bands differ from the Extremely High Frequency (EHF) band (30 GHz–300 GHz).

With the above in mind, and unless expressly stated otherwise, it should be understood that the terms "sub-6 GHz" and the like (if used herein) may refer broadly to frequencies less than 6 GHz, which may be within FR1, or may include mid-band frequency. Furthermore, unless expressly stated otherwise, it should be understood that the terms "mmWave" and the like, if used herein, may refer broadly to frequencies that include mid-band frequencies, may be within FR2, or may be within the EHF band.

5G NR devices, networks and systems can be implemented to use optimized OFDM-based beamforming features. These features can include scalable bit schemes and transmission time intervals (TTIs); a common, flexible framework for efficient multi-tasking with dynamic, low-latency time-division duplex (TDD) or frequency-division duplex (FDD) designs services and features; and improved wireless technologies, such as massive multiple-input, multiple-output (MIMO), robust mmWave transmission, advanced channel coding, and device-centric mobility. The scalability of the digital scheme in 5G NR, and the scaling of the subcarrier spacing can efficiently address the operation of diverse services across different spectrums and different deployments. For example, in various outdoor and macro coverage deployments less than 3GHz FDD or TDD implementations, the subcarrier spacing can be 15 kHz, for example, on bandwidths of 1, 5, 10, 20 MHz, etc. For other various outdoor and small cell coverage deployments of TDD greater than 3 GHz, the subcarrier spacing can be 30 kHz over the 80/100 MHz bandwidth. For various other indoor broadband implementations using TDD on the license-exempt portion of the 5 GHz band, the subcarrier spacing can be 60 kHz over a 160 MHz bandwidth. Finally, subcarrier spacing can be 120 kHz over a 500 MHz bandwidth for deployments using mmWave components transmitting at TDD at 28 GHz.

The scalable digital scheme of 5G NR facilitates scalable TTI for various 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 considers a self-contained integrated subframe design with uplink or downlink scheduling information, data and acknowledgments in the same subframe. Self-contained integrated subframes support communication in license-exempt or contention-based shared spectrum, self-adjusting uplink or downlink, in which case it can be flexibly configured on a per-cell basis to Dynamically switch between uplink and downlink to meet current traffic demand.

For clarity, certain aspects of these devices and techniques are described below with reference to exemplary 5G NR implementations or in a 5G-centric manner, and 5G terminology may be used as an illustrative example in portions of the following description; However, this description is not intended to be limited to 5G applications.

Furthermore, it should be understood that, in operation, a wireless communication network adapted according to the concepts herein may operate in any combination of licensed or unlicensed spectrum, depending on load and availability. Thus, it will be apparent to those having ordinary skill in the art that the systems, devices and methods described herein may be applied to other communication systems and applications in addition to the specific examples provided.

Although aspects and implementations have been described in this case by way of illustration of some examples, those of ordinary skill in the art to which this invention pertains will appreciate that additional implementations and use cases can be implemented in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, packaging arrangements. For example, various embodiments or uses may be implemented via integrated chip implementations or other non-modular component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail or purchasing devices, medical devices, AI-enabled devices, etc.) or a combination thereof. Various applicability of the described innovations may arise, although some examples may or may not be specific to a use case or application. Implementations can range from wafer-level or modular components to non-modular, non-wafer-level implementations, and can also be aggregated, decentralized, or original equipment manufacturer (OEM ) device or system. In some practical setups, devices incorporating the described aspects and features may also necessarily include other components and features in order to realize and practice the claimed and described aspects. Can be implemented in a wide variety of different sizes, shapes, and configurations (which include large or small devices, wafer-level components, multi-component systems (e.g., radio frequency (RF) chains, communication interfaces, processors), distributed arrangements , end-user devices, etc., to implement the innovations described herein.

1 is a block diagram illustrating details of an example 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 understood by those of ordinary skill in the art to which the present invention pertains, elements appearing in FIG. 1 may have relevant counterparts in other network arrangements, including, for example, cellular network arrangements and non-cellular network arrangements ( For example, device-to-device or peer-to-peer or ad hoc (ad hoc) network placement, etc.).

The wireless network 100 shown in FIG. 1 includes a plurality of base stations 105 and other network entities. A base station may be a station communicating with a UE, which may also be called an evolved Node B (eNB), a next generation eNB (gNB), an access point, and so on. Each base station 105 can provide communication coverage for a specific geographic area. In 3GPP, depending on the context in which the term "cell" is used, the term "cell" can refer to the specific geographic coverage area of the base station, or the base station subsystem serving the coverage area. In wireless network 100 implementations herein, base stations 105 may be associated with the same service provider or different service providers (eg, wireless network 100 may include multiple service provider wireless networks). Additionally, in the implementation of wireless network 100 herein, base station 105 may use one or more of the same frequencies (e.g., one or more frequency bands in licensed spectrum, license-exempt spectrum, or a combination thereof) as neighboring cells. to provide wireless communication. In some instances, a single 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.

A base station may provide communication coverage for macrocells or small cells (eg, picocells or femtocells) or other types of cells. Typically, a macrocell covers a relatively large geographic area (eg, several kilometers in radius), which allows unrestricted access by UEs with a service subscription with a network provider. Typically, small cells, such as picocells, cover a relatively small geographic area, which allows unrestricted access by UEs with a service subscription with a network provider. Furthermore, a small cell such as a femtocell typically covers a relatively small geographic area (e.g., a home), which, in addition to unfettered access, also gives UEs associated with the femtocell (e.g., closed subscriber UEs in a group (CSG), UEs for users in a home, etc.) provide restricted access. A base station for a macrocell may be referred to as a macrobase station. A base station for small cells may be referred to as a small cell base station, pico base station, femto base station, or home base station. In the example shown in FIG. 1, base stations 105d and 105e are general macro base stations, while base stations 105-a-105c are implementations in 3-dimensional (3D), full-dimensional (FD), or massive MIMO. A kind of macro base station. The base stations 105-a-105c take full advantage of their higher dimensional MIMO capabilities to utilize 3D beamforming in altitude and azimuth beamforming to increase coverage and capacity. The base station 105f is a small cell base station, which can be a home node or a portable access point. A base station can support one or more (eg, two, three, four, etc.) cells.

The wireless network 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations may have similar frame timing, with transmissions from different base stations being approximately aligned in time. For asynchronous operation, base stations may have different frame timings, and transmissions from different base stations are not aligned in time. In some scenarios, networking can be enabled or configured to handle dynamic switching between synchronous or asynchronous operations.

UEs 115 are dispersed in the wireless network 100, and each UE may be stationary or mobile. It should be understood that although in the standards and specifications promulgated by 3GPP, mobile devices are generally referred to as UEs, those skilled in the art to which the present invention pertains may also refer to such devices as mobile stations (MSs) in addition or in other ways. ), 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 End terminal, handheld device, terminal, user agent, mobile service client, client, gaming device, augmented reality device, vehicle component, vehicle equipment or vehicle mod or some other suitable term. In this document, a "mobile" device or UE does not necessarily have mobility capabilities and may be stationary. Some non-limiting examples of mobile devices (e.g., may include an implementation of one or more of UE 115) include mobile stations, cellular (cell) phones, smart phones, Session Initiation Protocol (SIP) phones, wireless domain loops ( WLL) stations, laptops, personal computers (PCs), notebooks, small notebooks, smart computers, tablet devices, and personal digital assistants (PDAs). Mobile devices may additionally be IoT or "Internet of Everything" (IoE) devices such as automobiles or other 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 arrays, municipal lighting, water or other infrastructure; industrial automation and enterprise equipment; consumer and wearable devices such as eyeglasses, wearable cameras , smart watches, health or fitness trackers, mammalian implantable devices, gesture tracking devices, medical devices, digital audio players (e.g., MP3 players), cameras, game consoles, etc.; and digital or smart homes Devices such as home audio, video and multimedia equipment, appliances, sensors, vending machines, smart lighting, home security systems, smart electricity meters and more. In one aspect, a UE may be a device including a Universal Integrated Circuit Card (UICC). In another aspect, a UE may be a device that does not include a UICC. In some aspects, a UE that does not include a UICC may also be referred to as an IoE device. UEs 115 - a - 115 d of the embodiment shown in FIG. 1 are examples of mobile smartphone type devices accessing wireless network 100 . The UE may also be a machine specially configured to realize connected communication, including machine type communication (MTC), enhanced MTC (eMTC), narrow-band IoT (NB-IoT), and so on. UEs 115e - 115k shown in FIG. 1 are examples of various machines configured to enable access to wireless network 100 .

A mobile device such as UE 115 is capable of communicating with any type of base station (whether macro base station, pico base station, femto base station, repeater, etc.). In Figure 1, a communication link (denoted as a lightning bolt) indicates a wireless transmission between a UE and a serving base station, or a desired transmission between base stations, and a backhaul transmission between base stations, where the serving base station is Specifies the base station serving the UE on the downlink or uplink. In some scenarios, a UE may operate as a base station or other network node. The backhaul communication between the base stations of the wireless network 100 can be performed using wired or wireless communication links.

When operating in wireless network 100, base stations 105-a-105c serve UE 115a and UE 115b using 3D beamforming and coordinated spatial techniques such as coordinated multipoint (CoMP) or multi-connectivity. The macro base station 105d performs backhaul communication with the base stations 105-a-105c and the small cell base station 105f. Macro base station 105d also transmits a multicast service that UEs 115c and 115d subscribe to and receive. Such multicast services may include mobile television or streaming video, or may include other services for providing cellular information (eg, weather emergencies or warnings such as amber alerts or gray alerts).

Embodiments of the wireless network 100 support mission-critical communications over ultra-reliable and redundant links for mission-critical devices (eg, UE 115e, which is a drone). Redundant communication links with UE 115e include communication links 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 directly communicate with base stations such as small cell base station 105f and macro base stations via wireless network 100 105e, or in a multi-hop configuration, via communication with another user equipment that relays its information to the network, for example UE 115f sends temperature measurement information to smart meter UE 115g, which is then communicated via a small The cell base station 105f reports to the network. For example, in a vehicle-to-vehicle (V2V) mesh network between UEs 115i-115k communicating with macro base station 105e, wireless network 100 may also provide additional network efficiency.

In some aspects of the present disclosure, base station 105 of FIG. 1 may transmit a frequency hopping (FH) indicator 150 to indicate to UE 115 whether frequency hopping is enabled or disabled for UE 115 . To illustrate, in some examples, base station 105d may send FH indicator 150 to UE 115c to indicate whether frequency hopping is enabled or disabled for UE 115c. UE 115c may enable or disable frequency hopping based on FH indicator 150, as described further below.

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 in FIG. 1 . For the restricted association scenario (as described above), the base station 105 may be the small cell base station 105f in FIG. The cell base station 105f, UE 115c or UE 115d will be included in the list of accessible UEs of the small cell base station 105f. Base station 105 may also be some other type of base station. As shown in FIG. 2, base station 105 may be equipped with antennas 234a through 234t, and UE 115 may be equipped with antennas 252a through 252r for facilitating wireless communication.

At the base station 105, a transmit processor 220 may receive data from a data source 212 and control information from a processor 240 (eg, a processor). The control information can be used for physical broadcast channel (PBCH), physical control format indicator channel (PCFICH), physical hybrid ARQ (automatic repeat request) indicator channel (PHICH), physical downlink control channel (PDCCH), Enhanced Physical Downlink Control Channel (EPDCCH), MTC Physical Downlink Control Channel (MPDCCH), etc. The material can be used for Physical Downlink Shared Channel (PDSCH), etc. Additionally, transmit processor 220 may perform processing (eg, encoding and symbol mapping) on the data and control information to obtain data symbols and control symbols, respectively. In addition, the transmit processor 220 can also generate reference symbols, eg, for primary synchronization signal (PSS) and secondary synchronization signal (SSS) and cell-specific reference signals. A transmit (TX) MIMO processor 230 may perform spatial processing (e.g., precoding) on these data symbols, control symbols, or reference symbols (if any) and provide an output symbol stream to modulators (MOD) 232a through 232t . For example, spatial processing performed on data symbols, control symbols or reference symbols may include precoding. Each modulator 232 may process a respective output symbol stream (eg, for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process (eg, convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from modulators 232a through 232t may be transmitted via antennas 234a through 234t, respectively.

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

On the uplink, at UE 115, transmit processor 264 may receive data from data source 262 (e.g., for a Physical Uplink Shared Channel (PUSCH)), from processor 280 (e.g., for PUSCH). link control channel (PUCCH)) control information, and process the data and control information. In addition, the transmit processor 264 can also generate reference symbols for reference signals. Symbols from transmit processor 264 may be precoded by TX MIMO processor 266 (if any), further processed by modulators 254a through 254r (e.g., for SC-FDM, etc.), and sent back to the base station 105. At base station 105, uplink signals from UE 115 may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if any), received by receive processor 238 Further processing is performed to obtain decoded data and control information sent by UE 115 . Receive processor 238 may provide decoded data to data slot 239 and decoded control information to processor 240 .

Processors 240 and 280 may direct the operation of 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 performance of various processes for implementing the techniques described herein, such as Other processes for performing or directing the execution of the functional modules shown in FIGS. 8-11 , or for implementing the techniques described herein (eg, the sending and receiving of the FH indicator 150 ). Memories 242 and 282 may store data and program codes for base station 105 and UE 115, respectively. The scheduler 244 can schedule the UE to perform data transmission on the downlink or uplink.

In some cases, UE 115 and base station 105 may operate in shared radio spectrum bands including licensed or license-exempt (eg, contention-based) spectrum. In the unlicensed frequency portion of the shared radio spectrum band, UE 115 or base station 105 may typically perform media sensing procedures to contend for access to the spectrum. For example, UE 115 or base station 105 may perform a listen-before-talk or listen-before-transmit (LBT) procedure (eg, Clear Channel Assessment (CCA)) prior to communication in order to determine whether a shared channel is available. In some implementations, 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 the received signal strength indicator (RSSI) of the power meter indicates that the channel is occupied. Specifically, signal power concentrated in a specific bandwidth and exceeding a predetermined noise floor may indicate another wireless transmitter. CCA may also include detection of specific sequences that indicate channel usage. For example, another device could send a specific preamble before sending a data sequence. In some cases, the LBT procedure may include acknowledgment/negative acknowledgment (ACK/NACK) feedback (as a proxy for collisions) by the wireless node based on the amount of energy detected on the channel or for packets it sends itself, to adjust its own backoff window.

3 is a block diagram illustrating an example of a wireless communication system 300 in accordance with some aspects of the present disclosure. Wireless communication system 300 may include one or more base stations (eg, base station 105). The wireless communication system 300 may also include one or more UEs (eg, UE 115x, UE 115y, and UE 115z). In some examples, UEs 115x-z correspond to UE 115 shown in FIG. 1 .

The example of FIG. 3 illustrates that base station 105 may include one or more processors (eg, processor 240 ) and may include memory 242 . The base station 105 may also include a transmitter 306 and a receiver 308 . Processor 240 may be coupled to memory 242 , transmitter 306 and receiver 308 . In some examples, transmitter 306 and receiver 308 include one or more components described with reference to FIG. or one or more of the TX MIMO processors 230. In some implementations, transmitter 306 and receiver 308 may be integrated in one or more transceivers of base station 105 .

Transmitter 306 may be configured to send reference signals, synchronization signals, control information, and data to one or more other devices, and receiver 308 may be configured to receive reference signals, control information, and data from one or more other devices. For example, transmitter 306 may be configured to send signaling, control information, and data to UEs 115x-z, and receiver 308 may be configured to receive signaling, control information, and data from UEs 115x-z.

Each UE 115x-z may include one or more processors (e.g., processor 280), memory (e.g., memory 282), transmitters (e.g., transmitter 356), and receivers (e.g., receiver 358 ). Processor 280 may be coupled to 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 FIG. 264 or TX MIMO processor 266. In some implementations, transmitter 356 and receiver 358 may be integrated in one or more transceivers of UE 115 .

Transmitter 356 may be configured to send reference signals, synchronization signals, control information, and data to one or more other devices, and receiver 358 may be configured to receive reference signals, control information, and data from one or more other devices. For example, in some implementations, transmitter 356 can be configured to send signaling, control information and data to base station 105 , and receiver 358 can be configured to receive signaling, control information and data from base station 105 .

In some implementations, one or more of transmitter 306, receiver 308, transmitter 356, or receiver 358 may include an antenna array. The antenna array may include multiple antenna elements for performing wireless communication with other devices. In some implementations, the antenna array can use different beams (also referred to as antenna beams) to perform wireless communications. These beams may include transmit beams and receive beams. For purposes of illustration, an antenna array may include multiple independent sets (or subsets) of antenna elements (or multiple individual antenna arrays), and each set of antenna elements of the antenna array may be configured to use a different corresponding The beams communicate, and these beams can have their own orientation different from other beams. For example, a first set of antenna elements of an 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. to communicate. In other embodiments, the antenna array may be configured to communicate via more than two beams. In some implementations, one or more sets of antenna elements of an antenna array may be configured to generate multiple beams simultaneously, eg, using multiple RF chains. A set (or subset) of antenna elements may include a plurality of antenna elements, such as two antenna elements, four antenna elements, ten antenna elements, twenty antenna elements, or any other number of antenna elements greater than two. Although described as an antenna array, in other embodiments, the antenna array may include or correspond to multiple antenna panels, and each antenna panel may be configured to communicate using a different respective beam.

In some implementations, the wireless communication system 300 can operate in accordance with a 5G NR network. For example, the wireless communication system 300 may include a plurality of 5G-enabled UEs 115 and a plurality of 5G-enabled base stations 105, e.g., configured to operate in accordance with 5G NR network protocols such as those defined by 3GPP UE and base station.

In some examples, one or more UEs may be associated with a particular capability type. In some examples, UEs 115x and 115z are associated with a first capability type, while 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, while the second capability type may correspond to a non-RedCap capability type, such as Embedded Mobile Broadband (eMBB) capability type, Ultra-Reliable Low Latency Communication (URLLC) capability type, or other capability types. In some instances, UE 115x and UE 115z may correspond to wearable devices, medical monitoring devices, sensor devices, Internet of Things (IoT) devices, or smart city devices (eg, surveillance cameras), as illustrative examples.

To further illustrate, in some implementations, UE 115x, UE 115y, and UE 115z may use a first uplink bandwidth part (BWP) 362 (eg, UE 115x's preset uplink BWP), a second uplink An uplink BWP 372 and a third uplink BWP 382 communicate with the base station 105. In some examples, first uplink BWP 362 and third uplink BWP 382 include less bandwidth than second uplink BWP 372 (e.g., to reduce power consumption associated with UE 115x and UE 115z ). Each of uplink BWPs 362, 372, and 382 may correspond to an initial uplink BWP or an active uplink BWP. For purposes of illustration, first uplink BWP 362 may correspond to an initial uplink BWP used by UE 115x prior to establishing a radio resource control (RRC) connection between base station 105 and UE 115x. In some other examples, the first uplink BWP 362 can 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.

During operation, the transmitter 356 may operate based on the first uplink BWP 362 . For example, transmitter 356 may be configured to send to base station 105 an uplink control channel transmission 330 within first uplink BWP 362 (e.g., where uplink control channel transmission 330 is sent by the frequency resource in BWP 362). The uplink control channel transmission 330 may indicate uplink control information (UCI) 334 associated with the UE 115x. In some examples, uplink control channel transmission 330 corresponds to a physical uplink control channel (PUCCH) transmission.

In some implementations, transmitter 356 may be configured to perform uplink control channel transmission 330 based on FH mode 360 . During operation based on the FH mode 360, the transmitter 356 may alternate between transmitting using a first subset of frequencies 364 of the first uplink BWP 362 and a second subset of frequencies 366 of the first uplink BWP 362 ( or "jump"). In some circumstances, performing uplink control channel transmission 330 based on FH mode 360 may be associated with reduced performance (eg, resource fragmentation) by one or more other UEs 115 .

For purposes of illustration, FIG. 4 is a diagram illustrating an example of a resource allocation scheme 400 according to some aspects of the present disclosure. In the example of resource allocation scheme 400, first uplink BWP 362 is smaller than second uplink BWP 372 (eg, includes a smaller frequency range than second uplink BWP 372). During operation of transmitter 356 based on FH mode 360, UE 115y may experience resource fragmentation. For example, if the transmitter 356 is using the first subset of frequencies 364 and the second subset of frequencies 366 during the FH mode 360, the frequencies corresponding to the first subset of frequencies 364 and the second subset of frequencies 366 may not be available (or Not assigned to) UE 115y. As a result, the resources of the second uplink BWP 372 may be separated (or segmented) into three discrete frequency ranges.

In some aspects of the present disclosure, base station 105 may transmit FH indicator 150 to selectively enable or disable FH mode 360 . Disabling FH mode 360 may reduce or avoid resource fragmentation for the second uplink BWP 372 . For example, when FH mode 360 is disabled, UE 115x may perform uplink control channel transmission 330 based on one (but not both) of first frequency subset 364 or second frequency subset 366, which may reduce or Fragmentation of the second uplink BWP 372 is avoided.

For further illustration, referring again to FIG. 3 , the base station 105 may send one or more messages 320 including the FH indicator 150 to the UE 115x. In some examples, UE 115x sends message 310 to base station 105 indicating a capability type 314 of UE 115x, and base station 105 sends FH indicator 150 to UE 115x based on capability type 314 . In some examples, capability type 314 indicates that UE 115x corresponds to a RedCap UE. In such instances, capability type 314 may correspond to a RedCap capability type, which may be associated with a reduced uplink Link bandwidth is associated. Alternatively or additionally, capability type 314 may indicate one or more other parameters, such as one or more of bandwidth or center frequency of first uplink BWP 362, as an illustrative example.

In some examples, message 310 corresponds to a type one message (msgl) associated with a four-step random access channel (RACH) procedure 342 indicating a capability type 314 (eg, a contention-based RACH procedure). In some such examples, the one or more messages 320 may include or correspond to one of: a type four message (msg4) associated with a four-step RACH procedure 342, a downlink message for scheduling msg4 Link control channel transmission, or a combination of downlink control channel transmission and downlink data channel transmission. In conjunction with a combination of downlink control channel transmission and downlink data channel transmission, including at least the first bit of the FH indicator 150 in the downlink control channel transmission and including the FH indicator in the downlink data channel transmission At least the second bit of 150. In such instances, UE 115x may perform joint decoding or joint processing of downlink control channel transmissions and downlink data channel transmissions to recognize FH indicator 150, which may increase transmission reliability of FH indicator 150 in some cases sex.

In some other examples, message 310 corresponds to a type three message (msg3) associated with four-step RACH procedure 342 and having one of the following: demodulation reference signal (DMRS) configuration to indicate capability type 314 , the payload used to indicate the capability type 314 , or the scrambling identifier used to indicate the capability type 314 . In some such examples, the one or more messages 320 may include or correspond to one of: a message four (msg4) associated with a four-step RACH procedure 342, a downlink for scheduling msg4 control channel transmission, or a combination of downlink control channel transmission and downlink data channel transmission.

In some other examples, the message 310 corresponds to a type A message (msgA) associated with a two-step RACH procedure 344 (eg, a contention-free RACH procedure) and having one of the following: for indicating the capability type 314 preamble, DMRS configuration indicating capability type 314 , payload indicating capability type 314 , or scrambling identifier for payload indicating 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 message for scheduling msgB Link control channel messages, or a combination of downlink control channel transmissions and downlink data channel transmissions.

For further illustration, in the example of the four-step RACH procedure 342, the UE 115x may send msgl to indicate the random access preamble selected by the UE 115x, and the base station 105 may send msg2 to indicate that the pair includes uplink resources Configure the response of the random access preamble. UE 115x may send msg3 to base station 105 using the uplink resource configuration, and base station 105 may send a contention resolution message to UE 115x via msg4. In an example of the two-step RACH procedure 344, the base station 105 may assign a random access preamble to the UE 115x and may indicate the assigned random access preamble to the UE 115x. UE 115x 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 UE 115x via msgB.

In some other examples, the one or more messages 320 may include or correspond to another message sent regardless of the RACH type associated with UE 115x. For example, the one or more messages 320 may include or correspond to system information (SI) messages associated with the base station 105 . In some examples, the base station 105 transmits the SI message using a broadcast technique, which may enable multiple UEs (eg, UEs 115x-z) to receive the SI message.

FH indicator 150 may include bit 324 having a value indicating whether FH mode 360 is enabled or disabled. To illustrate, bit 324 may indicate a first value, and transmitter 356 may perform 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 uplink control channel transmission 330 based on the second value of bit 324 . In such instances, transmitter 356 may perform uplink control channel transmission 330 using one (but not both) of first subset of frequencies 364 or second subset of frequencies 366 . In some implementations, the first value corresponds to a logical zero value and the second value corresponds to a logical one value. In some other implementations, the first value corresponds to a logical one value and the second value corresponds to a logical zero value.

In some implementations, the FH indicator 150 may optionally include a first set of one or more bits 326 for indicating the set of resources 346 within the first uplink BWP 362 . For example, memory 282 may store a table of resource sets, and first set of one or more bits 326 may correspond to an index to the resource set table. The processor 280 can identify the resource set 346 based on the first set of one or more bits 326 and the transmitter 356 can perform the uplink control channel transmission 330 based on the resource set 374 . In some examples, first set of one or more bits 326 may indicate first frequency subset 364 , second frequency subset 366 , or other frequency resources included in first uplink BWP 362 .

In some instances, at least a subset of resource sets 346 shares or partially overlaps with at least one other resource set of at least one other device, where the at least one other device has the same or a different capability type as UE 115x. For example, resource set 346 may include at least one common resource as resource set 374 for UE 115y, and UE 115y may have a different capability type than UE 115x. As another example, resource set 346 can include at least one common resource as resource set 384 for UE 115z, and UE 115z can have the same capability type as UE 115x. In some examples, resource set 374 may correspond to the initial uplink BWP or active uplink BWP of UE 115y, and resource set 384 may correspond to the initial uplink BWP or active uplink BWP of UE 115z.

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

Alternatively or additionally, the FH indicator 150 may optionally include a second set of one or more bits 328 for indicating the number of repetitions 348, and the transmitter 356 may perform an uplink control channel transmission based on the number of repetitions 348 One or more repetitions 332 of 330 . In some examples, performing one or more repetitions 332 may increase reliability associated with uplink control channel transmission 330 . To illustrate, disabling the FH mode 360 can reduce the frequency diversity gain associated with the uplink control channel transmission 330, and performing one or more repetitions 332 can compensate for the reduced frequency diversity gain (e.g., by increasing the frequency diversity gain associated with the uplink control channel transmission 330). control channel transmission 330 associated time diversity gain).

In some examples, base station 105 transmits one or more messages 320 using a broadcast transmission technique. Depending on the particular example, base station 105 may transmit one or more messages 320 (eg, using a broadcast transmission technique) before or after the initial access procedure for 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. According to this particular example, the base station 105 can send the one or more messages 320 using a unicast transmission technique and using one of an RRC connection or medium access control (MAC) control element (MAC-CE) signaling.

While some instances of uplink control channel transmission 330 may be described as a single signal or a single transmission, in some other examples uplink control channel transmission 330 may include multiple uplinks within first uplink BWP 362 road signal. In such instances, bits of UCI 334 may be allocated (or “shared”) among multiple uplink signals within first uplink BWP 362 . Furthermore, the FH indicator 150 may be shared among multiple uplink signals (eg, by enabling or disabling the FH mode 360 for each of the multiple uplink signals based on the value of bit 324 ). In some examples, as illustrative examples, the plurality of uplink signals includes a physical uplink control channel (PUCCH) signal, a physical uplink shared channel (PUSCH) signal, a sounding reference signal (SRS), or a physical random memory Get one or more of the channel (PRACH) signals.

5 is a diagram illustrating examples of a first uplink BWP 362, a second uplink BWP 372, and a third uplink BWP 382, according to some aspects of the present disclosure. Figure 5 illustrates that the first subset of frequencies 364 of the first uplink BWP 362 may be aligned with the first boundary 502 of the second uplink BWP 372 (eg, the lowest frequency included in the second uplink BWP 372) .

Aligning the first subset of frequencies 364 with the first boundary 502 of the second uplink BWP 372 can reduce or avoid resource fragmentation of the second uplink BWP 372 during operation of the transmitter 356 based on the FH pattern 360 . For example, if resources of the first subset of frequencies 364 are not available to UE 115y during uplink control channel transmission 330, UE 115y may use a contiguous set of resources 504 (e.g., instead of multiple non-contiguous resource group). In some instances, the number of packets sent by UE 115y may be reduced by reducing or avoiding resource fragmentation (e.g., by enabling material to be sent in a single packet using a contiguous set of resources 504 rather than using multiple non-contiguous resources groups are sent using multiple packets). As a result, data throughput and performance can be increased.

The example of FIG. 5 also illustrates that the first subset of frequencies 364 may be aligned with a third subset of frequencies 506 of a third uplink BWP 382 associated with a third device (eg, UE 115z). As a result, resource fragmentation of the second uplink BWP 372 due to transmissions by the UE 115z using the third subset of frequencies 506 may be reduced or avoided.

6 is a diagram illustrating additional examples of first uplink BWP 362, second uplink BWP 372, and third uplink BWP 382, according to some aspects of the present disclosure. 6 illustrates that a 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 (eg, UE 115z). In some implementations, the example of FIG. 6 can reduce interference between the transmissions of UE 115x and UE 115y (due to the use of different frequency subsets 364, 606 for the transmissions), while also enabling a contiguous set of resources for UE 115y 604, thereby reducing or avoiding resource segmentation for UE 115y.

Referring again to FIG. 3 , in some examples, base station 105 sets FH indicator 150 based on resource configuration 302 . Resource configuration 302 can track or indicate resources allocated to UEs (eg, UEs 115x-z) of wireless communication system 300 . As an illustrative example, 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 that the FH mode 360 is disabled, and may optionally via the first set of One or more bits 326 indicate usage of resources 366 of the second subset of frequencies. Alternatively or additionally, the base station 105 may perform alignment of the uplink BWP based on the resource configuration 302, for example by aligning the frequency subset 364, 506 with the first boundary 502, or by aligning the first frequency subset 364 Aligned with the first boundary 502 and the fourth subset of frequencies 606 is aligned with the second boundary 602 .

Although some examples have been described with reference to explicit FH indication techniques (eg, using bit 324), in some other examples UE 115 may decide whether to perform FH according to implicit FH indication techniques. Implicit FH indication techniques may be used instead of or in addition to explicit FH indication techniques. For example, in some implementations, if UE 115x fails to receive an explicit indication of FH indicator 150 from base station 105, UE 115x may use an implicit FH indication technique to decide whether to enable or disable FH mode 360. An example of an implicit FH indication technique is further described with reference to FIG. 7 .

7 is a block diagram illustrating another example of a wireless communication system 700, according to some aspects of the present disclosure. Wireless communication system 700 may include one or more base stations (eg, base station 105). The wireless communication system 300 may also include one or more UEs (eg, UE 115x, UE 115y, and UE 115z).

During operation, the base station 105 may transmit an indication of a bandwidth 712 associated with the base station 105 (eg, a serving cell system bandwidth associated with the base station 105). In some examples, base station 105 may send a system information (SI) message 710 including a first indication of bandwidth 712 . The base station 105 may send the first indication of the bandwidth 712 using a broadcast transmission technique.

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

The base station 105 may send 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, UE 115x may decode SI message 710 to identify first uplink BWP 362 . In some other examples, the second indication of the first uplink BWP 362 is included in the RRC configuration message 720 sent by the base station 105 to the UE 115x after the RRC connection is established with the UE 115x. In some such examples, UE 115x may decode RRC configuration message 720 to identify first uplink BWP 362 . In some other examples, the second indication of the first uplink BWP 362 may be included in another message. According to a particular example, first uplink BWP 362 may correspond to an initial BWP for UE 115x or an active BWP for UE 115x.

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

UE 115x may enable (or disable) FH mode 360 based on whether first uplink BWP 362 exceeds (or fails to exceed) threshold 750 . To illustrate, in some examples, processor 280 may determine that first uplink BWP 362 exceeds threshold 750 . In such instances, processor 280 can enable FH mode 360 and transmitter 356 can perform uplink control channel transmission 330 based on FH mode 360 . In some other examples, processor 280 may determine that first uplink BWP 362 failed to exceed threshold 750 . In such instances, processor 280 may disable FH mode 360 and transmitter 356 may perform uplink control channel transmission 330 without using FH mode 360 .

In some implementations, threshold 750 is based on bandwidth 712 and parameters 752 (eg, coefficients with positive or non-negative values). In some examples, threshold 750 corresponds to the product of bandwidth 712 and parameter 752 . In some implementations, parameters 752 are determined by network equipment (e.g., base station 105) and indicated to 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, base station 105 and UE 115x operate according to a certain wireless protocol (eg, a 5G NR wireless protocol), and the wireless protocol specifies parameters 752 based on one or more of the following: The bandwidth 712, the maximum bandwidth associated with the device type (eg, the maximum bandwidth supported by the capability type 314 of FIG. 3), or the first uplink BWP 362 configured by the network device based on the device type.

In some examples, one or more of the first frequency subset 364 or the second frequency subset 366 includes a first contiguous set of one or more physical resource blocks (PRBs). As a non-limiting illustrative example, the first frequency subset 364 may comprise a contiguous set of two contiguous PRBs, and the second frequency subset 366 may comprise a contiguous set of three contiguous PRBs.

In some examples, one or more of the first subset of frequencies 364 or the second subset of frequencies 366 spans a second contiguous group of symbols within a time slot or a third contiguous group of symbols within multiple time slots. For purposes of illustration, if one or more of the first frequency subset 364 or the second frequency subset 366 spans consecutive groups of symbols within a time slot, the FH pattern 360 may correspond to or may be referred to as an in-slot frequency hopping mode. If one or more of the first frequency subset 364 or the second frequency subset 366 spans consecutive groups of symbols within multiple time slots, the FH pattern 360 may correspond to or may be referred to as an inter-slot frequency hopping pattern .

In some examples, first subset of frequencies 364 does not overlap with second subset of frequencies 366 . For example, when FH mode 360 is enabled for uplink control channel transmission 330 in first uplink BWP 362, PRBs of first frequency subset 364 may not overlap with PRBs of second frequency subset 366 (and may not include in the PRBs of the second frequency subset 366).

One or more examples described herein may improve the performance of one or more UEs (eg, UE 115y). For example, by disabling FH mode 360 in one or more instances where first uplink BWP 362 is included in second uplink BWP 372, resource allocation associated with second uplink BWP 372 can be reduced or avoided. part. As a result, the number of packets that UE 115y uses to send data to base station 105 can be reduced, which in some cases can reduce latency.
