[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE), LTE-A, or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication with multiple communication devices, which may also be referred to as User Equipment (UE).

[0046] Figures 12 to 15A flowchart illustrating a method for supporting a BWP switching mode according to one or more aspects of this disclosure is shown. Detailed Implementation

[0047] Some wireless communication systems support wireless communication within multiple BWPs. For example, in the context of NR wireless communication, a user equipment (UE) can be configured with up to four active bandwidth portions for uplink and downlink transmissions between the UE and the base station. The term "active BWP" can be used to refer to a BWP used for wireless communication during a time interval. Therefore, by configuring multiple active BWPs for wireless communication, the UE can perform multiple transmissions with the base station within multiple active BWPs. For example, with multiple active BWPs configured, the UE can be configured to perform a first transmission and a second transmission, where the first and second transmissions at least partially overlap in the time domain, frequency domain, or both (e.g., concurrent transmission, simultaneous transmission). Configuring multiple BWPs can improve power performance and resource allocation. However, some wireless communication systems only support a single active BWP for sidelink communication, such as sidelink communication. In this regard, control signaling (e.g., RRC signaling from the base station) may be required whenever the UE is configured with different BWPs for sidelink communication. This can increase network overhead and traffic within the wireless communication system.

[0048] Therefore, techniques for signaling a BWP handover mode that can be used for sidelink communication, uplink / downlink communication, or both are disclosed. In some aspects, the UE can receive the BWP handover mode from the base station and perform sidelink communication with an attached UE according to the BWP handover mode. As used herein, a "BWP handover mode" may include a sequence of BWPs, wherein each BWP in the sequence is associated with wireless communication throughout a corresponding time interval (e.g., a first BWP for a first time interval, a second BWP for a second time interval). In some embodiments, the BWP handover mode can be used to configure sidelink communication between the UE and an attached UE, uplink / downlink communication between the UE and the base station, or both. In some aspects, the BWP handover mode may be indicated to the UE via RRC signaling, MAC-CE messages, or both.

[0049] In some cases, the UE can be configured (e.g., via RRC signaling) with a set of BWP handover modes for use in wireless communications (e.g., sidelink communications) at the UE. In this regard, the UE can be configured with one or more BWP handover modes and can subsequently receive DCI messages activating / deactivating, modifying, or both of the BWP handover modes. Furthermore, in some cases, the UE can send a request for a BWP handover mode and can receive a BWP handover mode in response to that request. Parameters associated with a BWP handover mode that can be indicated to the UE may include the period of the BWP handover mode, the start time of the BWP handover mode (e.g., time offset), the sequence of BWPs within the BWP handover mode, the time interval associated with each corresponding BWP, etc. The techniques described herein enable the configuration of UE signaling with BWP handover modes used for wireless communications (e.g., sidelink communications), thereby reducing control signaling overhead and improving resource utilization within the wireless communication system.

[0050] The aspects of this disclosure are initially described in the context of a wireless communication system. Additional aspects of this disclosure are described in the context of an example process flow. The aspects of this disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to the technology used for BWP handover modes.

[0051] Figure 1 An example of a wireless communication system 100 supporting technologies for BWP handover mode according to one or more aspects of this disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0052] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100 and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, on which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographical area, on which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0053] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary or mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 The diagram illustrates some example UE 115s. The UE 115 described in this document is capable of communicating with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown.

[0054] Base station 105 may communicate with core network 130, or with each other, or both. For example, base station 105 may interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) via backhaul links 120 (e.g., via X2, Xn, or other interfaces), or both. In some examples, backhaul link 120 may be or include one or more radio links.

[0055] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base transceiver station, radio base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home eNodeB or other suitable terms.

[0056] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, site, terminal, or client, among other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, meters, and other examples.

[0057] The UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115 that can sometimes act as relays, as well as base station 105 and network devices including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.

[0058] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio spectrum band (e.g., BWP) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating carrier operation, user data, or other signaling. Wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with UE 115. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0059] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Channel Number (EARFCN)) and can be located according to a channel grid for discovery by UE 115. A carrier may operate in standalone mode, where initial acquisition and connection can be performed by UE 115 via the carrier, or in non-standalone mode, where the connection is anchored using different carriers (e.g., the same or different radio access technologies).

[0060] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. A carrier may carry either downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0061] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, the two initial operating bands have been identified as frequency ranges named FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is generally (interchangeably) referred to as the “below 6GHz” band in various documents and articles. A similar naming issue sometimes arises with FR2, which is generally (interchangeably) referred to as the “millimeter wave” band in documents and articles, although it differs from the Extremely High Frequency (EHF) band (30GHz–300GHz) identified as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0062] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have identified the operating bands of these IF bands as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the characteristics of FR1 and / or FR2 to the IF band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating frequency bands have been identified as the frequency range designations FR4a or FR4–1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0063] In light of the foregoing, unless otherwise specifically stated, it should be understood that the terms "below 6 GHz," if used herein, can broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that the terms "millimeter wave," if used herein, can broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4a or FR4-1, and / or FR5, or may be within the EHF band.

[0064] A carrier can be associated with a bandwidth of the radio spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of several defined bandwidths of the carrier of a radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication via carrier bandwidth or can be configured to support communication via one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base station 105 or UE 115 that support simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each serving UE 115 can be configured to operate on a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0065] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate of the UE 115. Wireless communication resources can refer to a combination of radio spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity of communication with the UE 115.

[0066] One or more carrier parameter sets can be supported, where the parameter sets may include subcarrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP of a carrier can be active at a given time, and UE 115 communication can be restricted to one or more active BWPs.

[0067] The time interval of base station 105 or UE 115 can be expressed as a multiple of the basic time unit, for example, it can refer to T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N fThis can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0068] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple mini-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f Sampling period. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0069] A subframe, time slot, mini-slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0070] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region (e.g., a control resource set (CORESET)) of the physical control channel can be defined by multiple symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more UEs 115 can monitor or search control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates from one or more aggregation levels arranged in a concatenated manner. The aggregation level of the control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format with a given payload size. The search space set can include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0071] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., via a carrier) and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or others). In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of geographic coverage area 110 on which the logical communication entity operates. The extent of such a cell can range from a small area (e.g., a structure, a subset of structures) to a large area, depending on various factors such as the capabilities of base station 105. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, among other examples.

[0072] Macro cells can cover a relatively large geographical area (e.g., a radius of several kilometers) and allow UE 115 unrestricted access, where UE 115 has subscribed to a service from a network provider supporting macro cells. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed or unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a home or office). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0073] In some examples, a carrier can support multiple cells, and different cells can be configured based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband Internet of Things (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0074] In some examples, base station 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0075] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services such as Mission-Critical Push-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0076] In some examples, UE 115 is also able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates resource scheduling for D2D communication. In other cases, D2D communication is performed between UE 115s without the involvement of base station 105.

[0077] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. Vehicles may transmit information related to traffic conditions, signal control, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate via vehicle-to-network (V2N) communication through one or more network nodes (e.g., base station 105) with roadside infrastructure (such as roadside units) or with the network, or with both.

[0078] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to one or more network operator IP services 150. IP services 150 can include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0079] Some network devices, such as base station 105, may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0080] Wireless communication system 100 can operate using one or more frequency bands, such as in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is from approximately one decimeter to one meter. UHF waves may be blocked or deflected by buildings and environmental features, but these waves may penetrate structures sufficiently to allow macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0081] Wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 can employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on carrier aggregation configurations that combine component carriers (e.g., LAAs) operating in licensed bands. Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0082] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be juxtaposed at an antenna assembly such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in geographically dispersed locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports, which base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0083] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. Multiple signals can be transmitted, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0084] Beamforming, also known as spatial filtering, directional transmission, or directional reception, is a signal processing technique used at transmitting or receiving devices (e.g., base station 105, UE 115) to shape or guide antenna beams (e.g., transmit beams, receive beams) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating in a specific direction relative to the antenna array experience constructive interference, while others experience destructive interference. The adjustment of the signals transmitted via the antenna elements can include the transmitting or receiving device applying amplitude shift, phase shift, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each antenna element can be defined by a beamforming weight set associated with a specific direction (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other direction).

[0085] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) for beamforming operations to enable directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals based on different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions can be used (e.g., by a transmitting device such as base station 105, or by a receiving device such as UE 115) to identify the beam direction for later transmission or reception by base station 105.

[0086] Some signals (such as data signals associated with a receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with a receiving device such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0087] In some examples, transmission by a device (e.g., base station 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and this feedback may correspond to the number of beam configurations across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may be precoded or unprecoded. UE 115 may provide feedback for beam selection, which may be a precoded matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described in reference base station 105 for signals transmitted in one or more directions, UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying the beam direction of subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

[0088] A receiving device (e.g., UE 115) may attempt multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may attempt multiple receiving directions by receiving via different antenna subarrays, by processing signals received according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing signals received according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array, any of which can be referred to as “listening” according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiving configuration may be aligned in beam directions determined based on listening according to different receiving configuration directions (e.g., based on listening according to multiple beam directions being determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality).

[0089] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer layer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for transmission over logical channels. The MAC layer can perform priority processing and multiplexing from logical channels to transport channels. The MAC layer can also use error detection, error correction, or both to support MAC layer retransmissions to improve link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or core network 130 supporting user plane data radio bearers. At the physical layer, transport channels can be mapped to physical channels.

[0090] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception over communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve the throughput of the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in previous symbols within that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0091] In some aspects, the UE 115 and base station 105 of the wireless communication system 100 may support a technique for signaling a BWP handover mode, which can be used for sidelink communication, uplink / downlink communication, or both. For example, the UE 115 of the wireless communication system 100 may receive a BWP handover mode from the base station 105 and may perform sidelink communication with an additional UE 115 based on the BWP handover mode. In some implementations, the BWP handover mode may include a sequence of BWPs, where each BWP in the sequence is associated with wireless communication over a corresponding time interval (e.g., a first BWP for a first time interval, a second BWP for a second time interval). In some implementations, the BWP handover mode may be used to configure sidelink communication between the UE 115 and an additional UE 115, uplink / downlink communication between the UE 115 and the base station 105, or both. In some aspects, the BWP handover mode may be indicated to the UE 115 via RRC signaling, a MAC-CE message, or both.

[0092] In some cases, the UE 115 of the wireless communication system 100 can be configured (e.g., via RRC signaling) with a set of BWP handover modes, which can be used for wireless communication (e.g., sidelink communication) at each UE 115. In this regard, the UE 115 can be configured with one or more BWP handover modes and can subsequently receive DCI messages activating / deactivating a BWP handover mode, modifying a BWP handover mode, or both. Furthermore, in some cases, the UE 115 can send a request for a BWP handover mode and can receive a BWP handover mode in response to that request.

[0093] In some aspects, base station 105 may indicate to UE 115 one or more parameters associated with a BWP handover mode configured at the respective UE 115. Parameters associated with the BWP handover mode that may be indicated to UE 115 may include the period of the BWP handover mode, the start time of the BWP handover mode (e.g., time offset), the sequence of BWPs within the BWP handover mode, the time interval associated with each respective BWP, etc.

[0094] The techniques described herein enable UE 115 to be configured with one or more BWP handover modes for wireless communication at UE 115. UE 115 can be configured to perform sidelink communication, uplink / downlink communication, or both, depending on the configured BWP handover mode. In the context of sidelink communication, the techniques described herein enable UE 115 to be configured with multiple BWPs within a BWP handover mode, thereby reducing the amount of control signaling from the network used to configure BWPs for sidelink communication. Therefore, by enabling UE 115 to be configured with BWP handover modes including multiple BWPs, the techniques described herein reduce control signaling overhead and improve resource utilization within the wireless communication system 100.

[0095] Figure 2 An example of a wireless communication system 200 supporting techniques for BWP handover mode according to one or more aspects of this disclosure is illustrated. In some examples, the wireless communication system 200 may implement or be implemented by aspects of the wireless communication system 100. For example, the wireless communication system 200 may support signaling that enables UE 115 to be configured with BWP handover mode for wireless communication at the respective UE 115.

[0096] The wireless communication system 200 may include a base station 105-a, a first UE 115-a, a second UE 115-b, and a third UE 115-c, which may be referenced. Figure 1The example described is base station 105 and UE 115. First UE 115-a can communicate with base station 105-a using communication link 205-a, which can be an example of an NR or LTE link between first UE 115-a and base station 105-a. In some cases, communication link 205-a between first UE 115-a and base station 105-a may include an example of an access link (e.g., a Uu link), which may include a bidirectional link enabling both uplink and downlink communication. For example, first UE 115-a can use communication link 205-a to send uplink signals such as uplink control signals or uplink data signals to base station 105-a, and base station 105-a can use communication link 205-a to send downlink signals such as downlink control signals or downlink data signals to first UE 115-a.

[0097] Similarly, the first UE 115-a can communicate with the second UE 115-b and the third UE 115-c using communication links 205-b and 205-c, respectively. Communication links 205-b and 205-c can be examples of side-link communication links between the first UE 115-a, the second UE 115-b, and the third UE 115-c, respectively. In some cases, communication links 205-b and 205-c between the first UE 115-a and the second UE 115-b and the third UE 115-c can each include examples of PC5 links between UEs 115.

[0098] In some aspects, communication links 205-b and 205-c (e.g., sidelink communication links) between corresponding wireless devices can be included within the sidelink network of the wireless communication system 200. The sidelink network (e.g., a sidelink network including communication links 205-b and / or 205-c) can be configured to operate in "Mode 1" and / or "Mode 2". When operating in Mode 1, the sidelink network (e.g., communication links 205-b and 205-c) can be managed (e.g., coordinated) by the base station 105-a. In this regard, during Mode 1 operation, the base station 105-a can manage resource allocation on communication links 205-b and / or 205-c, and can allocate resource sets within communication links 205-b and 205-c to the corresponding UEs 115 (e.g., first UE 115-a, second UE 115-b, and third UE 115-c). In some cases, base station 105-a may allocate a set of sidelink resources to the corresponding UE 115 during Mode 1 operation via RRC signaling, DCI messages (e.g., DCI 3_0), or both. During Mode 1 operation, base station 105-a may allocate sidelink resources via dynamic granting, configuration granting (e.g., Type 1 configuration granting, Type 2 configuration granting), or both. In Mode 1 operation, the modulation and coding scheme (MCS) used for transmission across communication links 205-b and / or 205-c may be left to the corresponding UE 115, within the limits pre-configured at UE 115 and / or signaled by base station 105a.

[0099] In contrast, when operating in Mode 2, the sidelink network (e.g., communication link 205-b, communication link 205-c) may not be managed by base station 105-a (e.g., may not be coordinated). Without coordination or management of sidelink network resources during Mode 2 operation, UEs 115-a and 115-b can be configured to monitor the sidelink network and determine the set of sidelink resources available for transmitting sidelink signals via communication link 205-b and / or communication link 205-c. The first UE 115-a can "autonomously" determine the sidelink resources to be used in communication links 205-b and 205-c by monitoring communication links 205-b and 205-c (e.g., performing channel sensing) and blindly decoding the physical sidelink control channel (PSCCH) within each communication link 205 to identify sidelink resources reserved by other radio devices. Subsequently, the first UE 115-a can report the available sidelink resources to the upper layer and can allocate the set of sidelink resources to the second UE 115-b. In this regard, the Mode 2 operation of the sidelink network, including communication link 205-b and / or communication link 205-c, can follow a contention-based access procedure, in which various radio devices (e.g., UE 115) "compete" for use of the sidelink network, including communication link 205-b and communication link 205-c.

[0100] As previously mentioned, some wireless communication systems support only a single active BWP for sidelink communication, such as sidelink communication on sidelink communication link 205-b. In the context of mode 1 sidelink operation, base station 105a may send control signaling (e.g., RRC signaling) each time the first UE 115-a and / or the second UE 115-b wants to switch from one BWP to another. This increases the control signaling overhead within wireless communication system 200. Furthermore, in some cases, base station 105-a may not be able to enable both the first UE 115-a and the second UE 115-b to switch from one BWP to another simultaneously.

[0101] Therefore, the wireless communication system 200 can support a technique of transmitting a BWP handover mode via signaling, which can be used for sidelink communication, uplink / downlink communication, or both. For example, a first UE 115-a of the wireless communication system 200 can receive a BWP handover mode 225 from a base station 105-a and can perform sidelink communication with a second UE 115-b according to the BWP handover mode 225. Enabling UE 115 to be configured with the BWP handover mode 225 can reduce control signaling overhead within the wireless communication system 200. Furthermore, by reducing control signaling overhead, UE 115 can be configured with a BWP handover mode 225 including a narrow BWP, which can reduce the RF operating bandwidth at the corresponding UE 115 and improve the power performance at the UE 115.

[0102] For example, in some aspects, the first UE 115-a can receive RRC message 210 from base station 105-a. In some aspects, RRC message 210 may indicate a set of BWP handover modes 225 used by the first UE 115-a. Additionally or alternatively, the first UE 115-a may be configured (e.g., pre-configured) with the set of BWP handover modes 225 (e.g., pre-configured with BWP handover modes without using RRC message 210).

[0103] As previously described herein, each BWP handover mode 225 may include at least a first BWP 230 and a second BWP 230 different from the first BWP 230. More specifically, each BWP handover mode 225 may include a set of BWPs 230 for wireless communication performed during a set of time intervals 235, wherein each time interval 235 in the set of time intervals 235 is associated with a BWP 230 in the set of BWPs 230. For example, BWP handover mode 225-a may include a first BWP 230-a for wireless communication during a first time interval 235-a and a second BWP 230-b for wireless communication during a second time interval 235-b. Similarly, as another example, BWP handover mode 225-b may include a first BWP 230-c for wireless communication during a first time interval 235-c, a second BWP 230-d for wireless communication during a second time interval 235-c, and a third BWP 230-e for wireless communication during a third time interval 235-e.

[0104] In some aspects, each BWP switching mode 225 may include a sequence of BWP 230, wherein the sequence of BWP 230 is repeated according to period 240. For example, BWP switching mode 225-a may include a sequence of BWP 230, which includes a first BWP 230-a and a second BWP 230-b, wherein the sequence of BWP 230 (e.g., including the sequence of the first BWP 230-a and the second BWP 230-b) is repeated according to period 240-a. Similarly, BWP switching mode 225-b may include a sequence of BWP 230, which includes a first BWP 230-c, a second BWP 230-d, and a third BWP 230-e, wherein the sequence of BWP 230 (e.g., including the sequence of the first BWP 230-c, the sequence of the second BWP 230-d, and the third BWP 230-e) is repeated according to period 240-b.

[0105] In some implementations, the first UE 115-a may send a request 215 for BWP handover mode 225 to the base station 105-a. In some aspects, the first UE 115-a may send request 215 based on receiving RRC message 210. For example, in some cases, request 215 may indicate one or more BWP handover modes 225 included in the set 225 of BWP handover modes indicated in RRC message 210.

[0106] In some aspects, the first UE 115-a may send a request 215 for one or more BWP handover modes 225 based on one or more characteristics of the wireless communication network (e.g., traffic, traffic patterns, control signaling overhead, noise). For example, in some cases, the first UE 115-a may monitor the wireless communication network (e.g., monitor sidelink communication link 205-b), determine one or more parameters / characteristics of the wireless communication network (e.g., wireless communication system 200), and may send request 215 based on the determined parameters / characteristics of the wireless communication network. For example, the first UE 115-a may send a request 215 for BWP handover mode 225, which will reduce noise or interference, improve the quality or reliability of the transmission performed by the first UE 115-a, or any combination thereof.

[0107] Additionally or alternatively, the request 215 sent by the first UE 115-a may indicate parameters associated with BWP handover at the first UE 115-a, parameters associated with the wireless communication network, or both. For example, in some cases, request 215 may indicate a first set of parameters associated with BWP handover at the first UE 115-a, a second set of parameters associated with the wireless communication network, or both. Parameters associated with BWP handover at the first UE 115-a may include indications about which BWPs 230 are supported at the first UE 115-a, indications of BWP 230 width preferences in the frequency domain (e.g., a preference for wider or narrower BWPs 230), the duration of the BWP handover process at the first UE 115-a, the period 240 of the BWP handover mode 225, or any combination thereof. Furthermore, as previously described, parameters associated with the wireless communication network that may be indicated via request 215 may include identified traffic, traffic patterns, noise, control signaling overhead, or any combination thereof.

[0108] In some aspects, the first UE 115-a may receive a configuration 220 of BWP handover mode 225 for wireless communication performed at the first UE 115-a from the base station 105-a. In some aspects, the BWP handover mode 225 may be associated with sidelink communication between the first UE 115-a and the second UE 115-b, sidelink communication between the first UE 115-a and the third UE 115-c, uplink / downlink communication between the first UE 115-a and the base station 105-a, or any combination thereof. In some aspects, the configuration 220 of the BWP handover mode 225 may be indicated via control signaling including one or more PDSCH transmissions. For example, the configuration 220 of the BWP handover mode 225 may be indicated via PDSCH transmissions including RRC messages (e.g., RRC message 210), MAC-CE messages, or both.

[0109] In some aspects, the first UE 115-a may receive the configuration 220 of BWP handover mode 225 based on receiving RRC message 210, sending request 215, or both. For example, the configuration 220 of BWP handover mode 225 may include BWP handover mode 225, which is included in the set of BWP handover modes 225 indicated via RRC message 210. As another example, the base station 105-a may send the configuration 220 of BWP handover mode 225 based on (e.g., in response to) receiving request 215. In some cases, the base station 105-a may be based on (e.g., according to) one or more parameters and / or parameters of the wireless communication network associated with the BWP handover at the first UE 115-a, which are indicated via request 215. For example, where request 215 indicates the duration of the BWP handover process at the first UE 115-a, the BWP handover mode 225 indicated via configuration 220 may be based on the indication of the duration of the BWP handover process.

[0110] In some aspects, base station 105-a may additionally indicate one or more parameters associated with BWP handover mode 225 via configuration 220. For example, if configuration 220 for BWP handover mode 225 is indicated via PDSCH transmission, PDSCH transmission may include a set of parameters associated with BWP handover mode 225. Parameters associated with BWP handover mode 225 may include, but are not limited to, the period 240 of BWP handover mode 225, the sequence of BWPs 230 within BWP handover mode 225, an indication of the start time of BWP handover mode 225 (e.g., time offset 245 of BWP handover mode 225), a set of time intervals 235 associated with the set of BWPs 230 of BWP handover mode 225, the duration for which BWP handover mode 225 is to be applied (e.g., the number of cycles of BWP handover mode 225), or any combination thereof. Additionally or alternatively, configuration 220 may indicate whether communication performed according to BWP handover mode 225 is associated with unicast communication, broadcast communication, multicast communication, or any combination thereof.

[0111] For example, in some cases, the configuration 220 of the BWP switching mode 225 can be indicated via PDSCH, wherein the PDSCH transmission indicates a first BWP 230-a for wireless communication during a first time interval 235-a and a second BWP 230-b for wireless communication during a second time interval 235-b. In this example, the PDSCH transmission may indicate each of the first BWP 230-a and the second BWP 230-b, the duration of the first time interval 235-a and the second time interval 235-b, etc.

[0112] Additionally or alternatively, the PDSCH transmission may indicate the start time of BWP handover mode 225, which indicates the start time at which the first BWP 230 (e.g., BWP 230-a, BWP 230-c) of the first UE 115-a will activate BWP handover mode 225. In some cases, the start time of BWP handover mode 225 may be indicated via a time offset 245 measured relative to reference time 250. For example, if the first UE 115-a is configured with BWP handover mode 225-a, configuration 220 may indicate that the first UE 115-a will activate the first BWP 230-a of BWP handover mode 225-a after a time offset 245-a measured relative to reference time 250-a. In some cases, reference time 250-a may include the time when configuration 220 (e.g., the PDSCH transmission including configuration 220) is transmitted by base station 105-a, received by the first UE 115-a, or both. The reference time may additionally include any other time that may be offset from its measurement time by 245a.

[0113] In some aspects, the first UE 115-a may receive DCI message 255-a from base station 105-a. In some aspects, the first UE 115-a may receive DCI message 255-a based on receiving RRC message 210, transmission request 215, configuration 220 of receiving BWP handover mode 225 (e.g., PDSCH transmission including configuration 220), or any combination thereof. In some aspects, DCI message 255-a may include an indication to the first UE 115-a to begin performing communication (e.g., transmission 260) according to BWP handover mode 225. In this regard, DCI message 255-a may be referred to as “activating” BWP handover mode 225. For example, DCI message 255-a may include an indication for the first UE 115-a to perform wireless communication according to BWP handover mode 225, and therefore may include an indication for the first UE 115-a to activate the first BWP 230 of the corresponding BWP handover mode 225.

[0114] Additionally or alternatively, DCI message 255-a may adjust one or more parameters associated with BWP handover mode 225. For example, where the configuration 220 of BWP handover mode 225 is indicated via a PDSCH transmission including a set of parameters for BWP handover mode 225, DCI message 255-a may indicate at least one parameter that differs from the set of parameters for BWP handover mode 225. In this regard, the techniques described herein enable base station 105-a to selectively modify parameters of BWP handover mode 225 (e.g., BWP 230 within BWP handover mode 225, the sequence of BWP 230 within BWP handover mode 225, and the time interval 235 associated with each BWP 230 of BWP handover mode 225) without requiring a complete reconfiguration of the new BWP handover mode 225. In this regard, by enabling BWP handover mode 225 to be modified via DCI message 255, the techniques described herein can further reduce control signaling within a wireless communication network (e.g., wireless communication system 200).

[0115] In some aspects, the first UE 115-a can activate the first BWP 230 of the BWP handover mode 225. For example, when the first UE 115-a is configured with the BWP handover mode 225-a, the first UE 115-a can activate the first BWP 230-a of the BWP handover mode 225-a. As another example, when the first UE 115-a is configured with the BWP handover mode 225-b, the first UE 115-a can activate the first BWP 230-d of the BWP handover mode 225-b. As mentioned above, the first UE 115-a can activate the first BWP 230 of the corresponding BWP handover mode 225 in order to perform wireless communication based on the activated BWP 230. In some aspects, the first UE 115-a can activate the first BWP 230 based on performing a beam switching procedure, a BWP handover procedure, or both. In addition, the first UE 115-a can activate the first BWP 230 based on receiving RRC message 210, sending request 215, receiving BWP handover mode configuration 225, receiving DCI message 255-a, or any combination thereof.

[0116] For example, in some cases, the first UE 115-a can be configured to activate BWP handover mode 225-a (e.g., activate the first BWP 230-a of BWP handover mode 225-a) and begin performing wireless communication according to BWP handover mode 225-a once configuration 220 is received. In this case, the first UE 115-a can be configured to begin using BWP handover mode 225-a without receiving any further activation from base station 105-a. Conversely, as another example, the first UE 115-a can be configured to activate the first BWP 230-a of BWP handover mode 225-a and begin performing wireless communication according to BWP handover mode 225-a based on receiving activation of BWP handover mode 225-a. For example, the first UE 115-a can activate the first BWP 230-a of BWP handover mode 225-a based on receiving a DCI message 255-a that includes an indication of activation of BWP handover mode 225-a.

[0117] In some implementations, the first UE 115-a can send an indication of BWP handover mode 225 to the second UE 115-b. In some aspects, the first UE 115-a can send the indication of BWP handover mode 225 to the second UE 115-b based on performing a beam switching procedure, a BWP handover procedure, or both. Furthermore, the first UE 115-a can send the indication of BWP handover mode 225 to the second UE 115-b based on receiving an RRC message 210, sending a request 215, receiving a configuration 220 for BWP handover mode 225, receiving a DCI message 255-a, activating a first BWP 230 for BWP handover mode 225, or any combination thereof.

[0118] Sending an indication of BWP handover mode 225 to the second UE 115-b enables the second UE 115-b to perform wireless communication according to BWP handover mode 225. For example, when BWP handover mode 225-b is associated with sidelink communication between the first UE 115-a and the second UE 115-b, the first UE 115-a can notify the second UE 115-b of BWP handover mode 225b, allowing the first UE 115-a and the second UE 115-b to exchange sidelink transmissions (e.g., transmission 265) based on (e.g., according to) BWP handover mode 225-b. In some cases, notifying the second UE 115-b of BWP handover mode 225 can further reduce control signaling overhead within the wireless communication network and improve the robustness of wireless communication. For example, by sending an indication of BWP handover mode 225 to the second UE 115-b, the first UE 115-a can avoid sending control signaling to the second UE 115-b every time it wants to switch BWP 230 to conduct communication between the first UE 115-a and the second UE 115-b.

[0119] In some implementations, the first UE 115-a can send indications of BWP handover mode 225 to multiple UEs 115. For example, if configuration 220 indicates that BWP handover mode 225 is associated with broadcast and / or multicast communication, the first UE 115-a can send indications of BWP handover mode 225 to both the second UE 115-b and the third UE 115-c.

[0120] In an additional or alternative implementation, the first UE 115-a may send an indication of the first BWP 230 for the corresponding BWP handover mode 225, instead of indicating the entire BWP handover mode to the second UE 115-b. For example, if the first UE 115-a is configured with BWP handover mode 225-a, the first UE 115-a may send an indication of the first BWP 230-a to the second UE 115-b. As another example, if the first UE 115-a is configured with BWP handover mode 225-b, the first UE 115-a may send an indication of the first BWP 230-c to the second UE 115-b.

[0121] In some cases, the first UE 115-a can send an indication of the first BWP 230 instead of sending an indication of the complete BWP handover mode 225. By sending an indication of the first BWP 230 of the BWP handover mode 225, the first UE 115-a can communicate with the second UE 115-b based on (e.g., according to) the first BWP 230 of the configured BWP handover mode 225. Sending an indication of the first BWP 230 of the corresponding BWP handover mode 225 can additionally reduce the size of the indication compared to sending an indication of the entire BWP handover mode 225. However, it should be noted that sending an indication of a single BWP 230 may increase sidelink control signaling overhead compared to sending an indication of the entire BWP handover mode 225, as follows: In general, the first UE 115-a may need to send control signaling to the second UE 115-b every time it needs to perform wireless communication based on the new BWP 230 of the BWP handover mode 225.

[0122] As previously described, in some implementations, the first UE 115-a can send an indication of the first BWP 230 of the BWP handover mode 225 to multiple UEs 115. For example, if configuration 220 indicates that the BWP handover mode 225 is associated with broadcast communication and / or multicast communication, the first UE 115-a can send the indication of the first BWP 230 of the BWP handover mode 225 to the second UE 115-b and the third UE 115-c.

[0123] In some aspects, the first UE 115-a may send a first transmission 260-a to one or more devices in the wireless communication network based on (e.g., according to) BWP handover mode 225. For example, as Figure 2 As shown, the first UE 115-a may send a first transmission 260-a to base station 105-a, the second UE 115-b, or both. For example, when BWP handover mode 225 is associated with unicast sidelink communication, the first transmission 260-a may include a sidelink transmission from the first UE 115-a to the third device 305-a. As another example, when BWP handover mode 225 is associated with broadcast communication, multicast communication, or both, the first UE 115-a may send the first transmission 260-a to the second UE 115-b, the third UE 115-c, or both.

[0124] In some aspects, the first UE 115-a may transmit the first transmission 260-a based on receiving RRC message 210, sending request 215, receiving configuration 220 of BWP handover mode 225, receiving DCI message 255-a, activating the first BWP 320 of BWP handover mode 225, sending an indication of BWP handover mode 225 to the second UE 115-b, sending an indication of the first BWP 230 of BWP handover mode 225 to the second UE 115-b, or any combination thereof. For example, the first UE 115-a may transmit the first transmission 260-a based on (e.g., according to) the first BWP 230 of BWP handover mode 225, as indicated to the second UE 115-b.

[0125] In an additional or alternative implementation, the first UE 115-a may receive transmissions from base station 105-b, the second UE 115-b, the third UE 115-c, or any combination thereof, according to BWP handover mode 225. For example, as Figure 2 As shown, the first UE 115-a can receive sidelink transmission 265 from the second UE 115-b, wherein the sidelink transmission 265 is sent / received according to the BWP handover mode 225. For example, the second UE 115-b can send the sidelink transmission 265 according to the first BWP 230 of the corresponding BWP handover mode 225.

[0126] In some cases, the first UE 115-a may send an indication to the second UE 115-b, the third UE 115-c, or both, of a BWP handover procedure from the first BWP 230 of the BWP handover mode 225 to the second BWP 230 of the BWP handover mode 225. For example, if the first UE 115-a does not notify the second UE 115-b of the full BWP handover mode 225, the first UE 115-a may instruct the first UE 115-a to switch from the first BWP 230 of the corresponding BWP handover mode to the second BWP 230. For example, if the first UE 115-a is configured to perform sidelink communication with the second UE 115-b based on the BWP handover mode 225-b, the first UE 115-a may send an indication that the first UE 115-a (and the second UE 115-b) want to perform a BWP handover procedure from the first BWP 230-c of the BWP handover mode to the second BWP 230-d. In this regard, the first UE 115-a can send an instruction to the second UE 115-b that subsequent transmissions between the first UE 115-a and the second UE 115-b can be performed based on (e.g., according to) the second BWP 230-d of BWP handover mode 225-b. Conversely, it should be noted that if the first UE 115-a sends an instruction for the entire BWP handover mode 225, a separate instruction for the BWP handover process may be unnecessary.

[0127] In some aspects, the first UE 115-a can perform a BWP handover procedure from a first BWP 230 to a second BWP 230 configured in BWP handover mode 225 to activate the second BWP 230. For example, if the first UE 115-a is configured with BWP handover mode 225-b, the first UE 115-a can perform a BWP handover procedure from a first BWP 230-c to a second BWP 230-d to activate the second BWP 230-d. In some cases, the BWP handover procedure may include a beam switching procedure. The first UE 115-a can be configured to perform the BWP handover procedure based on (e.g., according to) BWP handover mode 225. Furthermore, the first UE 115-a can be configured to perform the BWP handover procedure based on sending an instruction to the second UE 115-b of BWP handover mode 225, based on sending an instruction to the second UE 115-b of the BWP handover procedure, or both. For example, the first device 305-b can perform a BWP handover procedure from the first BWP 230-c to the second BWP 230-d in BWP handover mode 225-b to activate the second BWP 230-d and perform subsequent transmissions based on the second BWP 230-d. In this regard, the first UE 115-a can activate the second BWP 230 in BWP handover mode 225 based on the execution of the BWP handover procedure.

[0128] After performing the BWP handover procedure, the first UE 115-a can send a second transmission 260-b to one or more devices in the wireless communication network based on (e.g., according to) BWP handover mode 225. For example, as Figure 2 As shown, the first UE 115-a can send the second transmission 260-b to base station 105-a, the second UE 115-b, the third UE 115-c, or any combination thereof. For example, when BWP handover mode 225 is associated with unicast communication, the second transmission 260-b may include a sidelink transmission from the first UE 115-a to the second UE 115-b. As another example, when BWP handover mode 225 is associated with broadcast communication, multicast communication, or both, the first UE 115-a can send the second transmission 260-b to the second UE 115-b, the third UE 115-c, or both.

[0129] In some aspects, the first UE 115-a may send the second transmission 260-b based on receiving RRC message 210, sending request 215, receiving configuration 220 of BWP handover mode 225, receiving DCI message 255-a, activating the first BWP 230 of BWP handover mode 225, sending an indication of BWP handover mode 225 to the second UE 115-b, sending an indication of the first BWP 320 to the second UE 115-b, sending the first transmission 260-a, sending an indication of BWP handover procedure, performing the BWP handover procedure, activating the second BWP 230 of BWP handover mode 225, or any combination thereof.

[0130] For example, the first UE 115-a may transmit the second transmission 260-b based on (e.g., according to) the second BWP 230-b of BWP handover mode 225-a. As another example, the first UE 115-a may be configured to transmit the first transmission 260-a and / or the second transmission 260-b based on (e.g., according to) a set of parameters associated with the BWP handover mode 225 indicated via configuration 220 (e.g., via a PDSCH transmission indicating BWP handover mode 225).

[0131] In some aspects, the first UE 115-a may receive DCI message 255-b from base station 105-a. In some aspects, DCI message 255-b may include an instruction for the first UE 115-a to avoid performing subsequent transmissions according to BWP handover mode 225. In this regard, DCI message 255-b may be referred to as “deactivating” BWP handover mode 225. In such a case, the first UE 115-a may be configured to avoid performing any subsequent transmissions 260, which may be performed according to different configurations 220 (e.g., default BWP handover mode 225, default wireless communication configuration 220), or any combination thereof. Additionally or alternatively, DCI message 255-b may adjust one or more parameters associated with BWP handover mode 225.

[0132] The first UE 115-a may send a third transmission 260-c to one or more devices in the wireless communication network (e.g., base station 105-a, second UE 115-b, or both). In some aspects, the first UE 115-a may send the third transmission 260-c based on (e.g., according to) DCI message 255-b. For example, if DCI message 255-b instructs the first UE 115-a to avoid performing subsequent transmission 260 according to BWP handover mode 225 (e.g., DCI message 255 deactivates BWP handover mode 225), the first UE 115-a may send the third transmission according to a second configuration 220 that is different from the configuration 220 of BWP handover mode 225. In this example, the second configuration 220 may include a second configuration 220 associated with a second (e.g., default) BWP handover mode 225 that is different from the original BWP handover mode 225. In an additional or alternative scenario, the first UE 115-a may avoid performing subsequent transmissions 260 (e.g., avoiding third transmission 260-c) if DCI message 255-b deactivates BWP handover mode 225. In such a case, the first UE 115-a may avoid performing third transmission 260-c (and other transmissions) until the first UE 115-a receives an additional DCI message 255 reactivating BWP handover mode 225 and / or activating a new BWP handover mode 225.

[0133] Alternatively or additionally, the third transmission 260-c may be performed based on the allocation of time / frequency resources received from the second device 305-c (e.g., according to dynamic licensing). As another example, if the DCI message 255-b modifies one or more parameters associated with the BWP handover mode 225, the third transmission 260-c may be performed based on the modified parameters indicated via the DCI message 255-b.

[0134] The techniques described herein enable a first UE 115-c to be configured with one or more BWP handover modes 225, which can be used for wireless communication at a first UE 115-a. UE 115 can be configured to perform sidelink communication, uplink / downlink communication, or both, according to the configured BWP handover mode 225. In the context of sidelink communication, the techniques described herein enable UE 115 to be configured with multiple BWPs within BWP handover mode 225, thereby reducing the amount of control signaling from the network used to configure BWPs for sidelink communication. Therefore, by enabling UE 115 to be configured with BWP handover mode 225 including multiple BWPs, the techniques described herein can reduce control signaling overhead and improve resource utilization within the wireless communication system.

[0135] Figure 3An example of a process flow 300 supporting a technology for a BWP handover mode according to one or more aspects of this disclosure is illustrated. In some examples, process flow 300 may implement aspects of wireless communication system 100, wireless communication system 200, or both, or be implemented therein. For example, process flow 300 may illustrate a first device 305-a receiving a BWP handover mode from a base station and performing wireless communication (e.g., sidelink transmission, uplink transmission) according to the indicated BWP handover mode, as shown in reference... Figures 1-2 As described.

[0136] In some cases, process flow 300 may include devices of a wireless communication network, including a first device 305-a, a second device 305-b, and a third device 305-c, which may be examples of the corresponding devices described herein. Figure 3 The first device 30-5a and the third device 305-c illustrated herein may include, respectively, as shown in the figure. Figure 2 Examples of the first UE 115-a and the second UE 115-b are illustrated. Similarly, Figure 3 The second device 305-b illustrated herein may include Figure 2 An example of base station 105-a is shown in the figure.

[0137] In some examples, the operations illustrated in process flow 300 can be performed by hardware (e.g., including circuits, processing blocks, logic components, and other components), code executed by a processor (e.g., software or firmware), or any combination thereof. Alternative examples of the following can be implemented, in which some steps are performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or more steps may be added.

[0138] At 310, the first device 305-a (e.g., the first UE 115) can receive RRC messages from the second device 305-b (e.g., base station 105). In some aspects, the RRC message may indicate a set of BWP handover modes that can be used by the first device 305-a. Additionally or alternatively, the first device 305-a may be configured (e.g., pre-configured) with a set of BWP handover modes.

[0139] At 315, the first device 305-a may send a request for a BWP handover mode to the second device 305-b. In some aspects, the first device 305-a may send the request at 315 based on receiving an RRC message at 310. For example, in some cases, the request may indicate one or more BWP handover modes included in the set of BWP handover modes indicated in the RRC message received at 310.

[0140] In some aspects, the first device 305-a may request one or more BWP handover modes based on one or more characteristics of the wireless communication network (e.g., traffic, control signaling overhead, noise). For example, in some cases, the first device 305-a may monitor the wireless communication network (e.g., monitor a sidelink communication link), determine one or more parameters / characteristics of the wireless communication network, and may send a request based on the determined parameters / characteristics of the wireless communication network. For example, the first device 305-a may request a BWP handover mode that reduces noise or interference, improves the quality or reliability of the transmission performed by the first device 305-a, or any combination thereof.

[0141] Additionally or alternatively, the request sent by the first device 305-a may indicate parameters associated with BWP handover at the first device 305-a, parameters associated with the wireless communication network, or both. For example, in some cases, the request sent at 325 may indicate a first set of parameters associated with BWP handover at the first device 305-a, a second set of parameters associated with the wireless communication network, or both. Parameters associated with BWP handover at the first device 305-a may include indications about which BWPs are supported at the first device 305-a, indications of BWP width preferences in the frequency domain (e.g., preference for wider or narrower BWPs), the duration of the BWP handover process at the first device 305-a, the period of the BWP handover mode, or any combination thereof. Furthermore, as previously described, parameters associated with the wireless communication network that may be indicated via the request may include identified traffic, noise, control signaling overhead, or any combination thereof.

[0142] At 320, the first device 305-a can receive from the second device 305-b a configuration of a BWP handover mode for wireless communication performed at the first device 305-a. In some aspects, the BWP handover mode may be associated with sidelink communication between the first device 305-a and the third device 305-c, uplink / downlink communication between the first device 305-a and the second device 305-b, or both. The BWP handover mode may include at least a first BWP and a second BWP different from the first BWP. More specifically, the BWP handover mode may include a set of BWPs for wireless communication performed during a set of time intervals, wherein each time interval in the set of time intervals is associated with a BWP in that set of BWPs. For example, the BWP handover mode may include a first BWP for wireless communication during a first time interval, a second BWP for wireless communication during a second time interval, etc. In some aspects, the configuration of the BWP handover mode may be indicated via control signaling including one or more PDSCH transmissions. For example, the configuration of the BWP handover mode may be indicated via a PDSCH transmission including an RRC message, a MAC-CE message, or both.

[0143] In some aspects, the first device 305-a may receive a BWP handover mode configuration at 320 based on receiving an RRC message at 310, sending a request at 315, or both. For example, the BWP handover mode configuration indicated at 320 may include BWP handover modes included in the set of BWP handover modes indicated via the RRC message at 310. As another example, the second device 305-b may send a BWP handover mode configuration at 320 based on (e.g., in response to) receiving a request at 315. In some cases, the second device 305-b may send the BWP handover mode configuration based on (e.g., according to) one or more parameters associated with the BWP handover at the first device 305-a and / or parameters of the wireless communication network (which are indicated via the request at 315). For example, if the request indicates the duration of the BWP handover process at the first device 305-a, the BWP handover mode indicated at 320 may be based on the indication of the duration of the BWP handover process.

[0144] In some aspects, the second device 305-b may additionally indicate one or more parameters associated with the BWP switching mode at 320. For example, in cases where the configuration of the BWP switching mode is indicated via a PDSCH transmission, the PDSCH transmission may include a set of parameters associated with the BWP switching mode. Parameters associated with the BWP switching mode may include, but are not limited to, the period of the BWP switching mode, the sequence of BWPs within the BWP switching mode, an indication of the start time of the BWP switching mode (e.g., a time offset of the BWP switching mode), a set of time intervals associated with the set of BWPs in the BWP switching mode, the duration for which the BWP switching mode is to be applied (e.g., the number of cycles of the BWP switching mode), or any combination thereof.

[0145] For example, in some cases, the BWP handover mode indicated at 320 via PDSCH transmission may include a first BWP for wireless communication during a first time interval and a second BWP for wireless communication during a second time interval. In this example, the PDSCH transmission may indicate each of the first and second BWPs, the duration of the first and second time intervals, etc. Additionally or alternatively, the PDSCH transmission may indicate the start time (e.g., time offset) of the BWP handover mode, which instructs the first device 305-a to activate the first BWP of the BWP handover mode based on (e.g., according to) the indicated start time and / or time offset.

[0146] At 325, the first device 305-a can receive DCI messages from the second device 305-b. In some aspects, the first device 305-a can receive DCI messages based on a configuration of receiving an RRC message at 310, sending a request at 315, receiving a BWP handover mode at 320, or any combination thereof.

[0147] In some aspects, the DCI message received at 325 may include an indication that the first device 305-a is to begin transmission according to the BWP handover mode. In this regard, the DCI message may be referred to as "activating" the BWP handover mode. For example, the DCI message may include an indication for the first device 305-a to perform wireless communication according to the BWP handover mode, and therefore may include an indication for the first device 305-a to activate the first BWP handover mode.

[0148] Additionally or alternatively, the DCI message received at 325 may adjust one or more parameters associated with the BWP handover mode. For example, if the BWP handover mode is indicated via a PDSCH transmission at 320 that includes a set of parameters for the BWP handover mode, the DCI message may indicate at least one parameter that is different from the set of parameters for the BWP handover mode. In this regard, the techniques described herein enable the second device 305-b to selectively modify parameters of the BWP handover mode (e.g., BWPs within the BWP handover mode, the BWP sequence within the BWP handover mode, and the time interval associated with the corresponding BWPs in the BWP handover mode) without requiring a complete reconfiguration of the new BWP handover mode. In this regard, by enabling the BWP handover mode to be modified via DCI messages, the techniques described herein can further reduce control signaling within the wireless communication network.

[0149] At 330, the first device 305-a can activate the first BWP in BWP handover mode. As previously described, the first device 305-a can activate the first BWP in BWP handover mode to perform wireless communication based on the activated BWP. In some aspects, the first device 305-a can activate the first BWP based on performing a beam switching procedure, a BWP handover procedure, or both. Furthermore, the first device 305-a can activate the first BWP based on receiving an RRC message at 310, sending a request at 315, receiving a configuration of the BWP handover mode at 320, receiving a DCI message at 325, or any combination thereof.

[0150] For example, in some cases, the first device 305-a can be configured to activate the first BWP in BWP switching mode and begin performing wireless communication according to the BWP switching mode upon receiving configuration at 320. In such a case, the first device 305-a can be configured to begin using the BWP switching mode without receiving any further activation from the second device 305-b. Conversely, as another example, the first device 305-a can be configured to activate the first BWP switching mode and begin performing wireless communication according to the BWP switching mode based on receiving activation of the BWP switching mode. For example, the first device 305-a can activate the first BWP in BWP switching mode based on receiving a DCI message at 325 that includes an indication of activation of the BWP switching mode.

[0151] At point 335, the first device 305-a can send an indication of the BWP handover mode to the third device 305-c. In some aspects, the first device 305-a can send the indication of the BWP handover mode to the third device 305-c based on performing a beam switching procedure, a BWP handover procedure, or both. Furthermore, the first device 305-a can send the indication of the BWP handover mode based on receiving an RRC message at point 310, sending a request at point 315, receiving a BWP handover mode configuration at point 320, receiving a DCI message at point 325, activating the BWP handover mode at point 335, or any combination thereof.

[0152] Sending an indication of the BWP handover mode to the third device 305-c enables the third device 305-c to perform wireless communication according to the BWP handover mode. For example, when the BWP handover mode is associated with sidelink communication between the first device 305-a and the third device 305-c, the first device 305-a can notify the third device 305-c of the BWP handover mode at 335, so that the first device 305-a and the third device 305-c can exchange sidelink transmissions based on (e.g., according to) the BWP handover mode. In some cases, notifying the third device 305-c of the BWP handover mode can further reduce control signaling overhead within the wireless communication network and improve the robustness of wireless communication. For example, by sending an indication of the BWP handover mode to the third device 305-c, the first device 305-a can avoid sending control signaling to the third device 305-c every time it needs to switch the BWP for communication between the first device 305-a and the third device.

[0153] At 340, the first device 305-a may send an indication of the first BWP for the BWP handover mode. In some cases, the first device 305-a may send the indication of the first BWP at 340 instead of sending the indication of the complete BWP handover mode at 335. By sending the indication of the first BWP for the BWP handover mode, the first device 305-a can communicate with the third device 305-c based on (e.g., according to) the first BWP. Sending the indication of the first BWP can additionally reduce the size of the indication compared to sending the indication of the entire BWP handover mode. However, it should be noted that sending the indication of a single BWP may increase control signaling overhead compared to sending the indication of the BWP handover process, because the first device 305-a may send control signaling to the third device 305-c each time wireless communication is to be performed according to the new BWP for the BWP handover mode.

[0154] At 345, the first device 305-a can send a first transmission to one or more devices in the wireless communication network based on (e.g., according to) a BWP handover mode. For example, as Figure 3 As shown, the first device 305-a can send a first transmission to the second device 305-b, the third device 305-c, or both. For example, if both the first device 305-a and the third device 305-c include UE115, the first transmission may include a sidelink transmission from the first device 305-a to the third device 305-a.

[0155] In some aspects, the first device 305-a may transmit a first transmission at 345 based on receiving an RRC message at 310, sending a request at 315, receiving a BWP handover mode configuration at 320, receiving a DCI message at 325, activating a first BWP handover mode at 335, sending an indication of the BWP handover mode at 335, sending an indication of the first BWP at 340, or any combination thereof. For example, the first device 305-a may transmit the first transmission at 345 based on (e.g., according to) the first BWP handover mode.

[0156] At 350, the first device 305-a may send an indication to the third device 305-c of a BWP handover process from the first BWP in BWP handover mode to the second BWP in BWP handover mode. For example, if the first device 305-a does not notify the third device 305-c of the complete BWP handover mode at 335, the first device 305-a may instruct itself to switch from the first BWP to the second BWP. In this regard, the first device 305-a may send an indication to the third device 305-c that subsequent transmissions between the first device 305-a and the third device 305-c may be performed based on (e.g., according to) the second BWP handover mode. Conversely, it should be noted here that if the first device 305-a sends an indication of the entire BWP handover mode at 335, a separate indication of the BWP handover process may be unnecessary.

[0157] At position 355, the first device 305-a can perform a BWP handover procedure from the first BWP to the second BWP to activate the second BWP. The first device 305-a can be configured to perform the BWP handover procedure based on (e.g., according to) a BWP handover mode. Furthermore, the first device 305-a can be configured to perform the BWP handover procedure based on an indication of a BWP handover mode sent at position 335, an indication of a BWP handover procedure sent at position 350, or both. For example, the first device 305-b can perform a BWP handover procedure from the first BWP to the second BWP to activate the second BWP and perform subsequent transmissions based on the second BWP.

[0158] At 360, the first device 305-a can activate the second BWP in BWP switching mode. In some aspects, the first device 305-a can activate the second BWP based on performing a BWP switching procedure at 355.

[0159] At point 365, the first device 305-a can send a second transmission to one or more devices in the wireless communication network based on (e.g., according to) a BWP handover mode. For example, as Figure 3 As shown, the first device 305-a can send a second transmission to the second device 305-b, the third device 305-c, or both. For example, if both the first device 305-a and the third device 305-c include UE115, the second transmission may include a sidelink transmission from the first device 305-a to the third device 305-a.

[0160] In some aspects, the first device 305-a may transmit a second transmission at 365 based on receiving an RRC message at 310, sending a request at 315, receiving a BWP handover mode configuration at 320, receiving a DCI message at 325, activating a first BWP handover mode at 335, sending an indication of the BWP handover mode at 335, sending an indication of the first BWP at 340, sending a first transmission at 345, sending an indication of the BWP handover process at 350, performing the BWP handover process at 355, activating a second BWP handover mode at 360, or any combination thereof. For example, the first device 305-a may transmit a second transmission at 365 based on (e.g., according to) the second BWP handover mode. As another example, the first device 305-a may be configured to send a first transmission at 345, a second transmission at 365, or both, based on (e.g., according to) a set of parameters associated with the BWP switching mode indicated at 320 (e.g., indicated via a PDSCH transmission indicating the BWP switching mode).

[0161] At 370, the first device 305-a can receive a DCI message from the second device 305-b. In some aspects, the DCI message received at 365 may include an instruction from the first device 305-a to avoid performing subsequent transmissions according to the BWP handover mode. In this regard, the DCI message may be referred to as "deactivating" the BWP handover mode. In such a case, the first device 305-a can be configured to avoid performing any subsequent transmissions, which may be performed according to different configurations (e.g., default BWP handover mode, default wireless communication configuration), or any combination thereof. Additionally or alternatively, the DCI message received at 370 may adjust one or more parameters associated with the BWP handover mode.

[0162] At 375, the first device 305-a can send a third transmission to one or more devices in the wireless communication network. In some aspects, the first device 305-a can send the third transmission at 375 based on (e.g., according to) a DCI message received at 370. For example, if the DCI message instructs the first device 305-a to avoid performing subsequent transmissions according to a BWP handover mode (e.g., the DCI message deactivates the BWP handover mode), the first device 305-a can send the third transmission according to a second configuration different from the BWP handover mode. In this example, the second configuration may include a second configuration associated with a second (e.g., default) BWP handover mode different from the original BWP handover mode. Additionally or alternatively, the third transmission can be performed based on the allocation of time / frequency resources received from the second device 305-c (e.g., according to dynamic licensing). As another example, if the DCI message received at 370 modifies one or more parameters associated with the BWP handover mode, the third transmission can be performed according to the modified parameters indicated via the DCI message.

[0163] In additional or alternative scenarios, if the DCI message deactivates the BWP switching mode, the first device 305-a may avoid performing subsequent transmissions (e.g., avoid performing a third transmission at 375). In such a case, the first device 305-a may avoid performing the third transmission (and other transmissions) until the first device 305-a receives an additional DCI message reactivating the BWP switching mode and / or activating a new BWP switching mode.

[0164] The techniques described herein enable a first device 305-a to be configured with one or more BWP handover modes for wireless communication at the first device 305-a. Device 305 can be configured to perform sidelink communication, uplink / downlink communication, or both, depending on the configured BWP handover mode. In the context of sidelink communication, the techniques described herein enable device 305 to be configured with multiple BWPs within a BWP handover mode, thereby reducing the amount of control signaling from the network used to configure BWPs for sidelink communication. Therefore, by enabling device 305 to be configured with BWP handover modes including multiple BWPs, the techniques described herein can reduce control signaling overhead and improve resource utilization within the wireless communication system.

[0165] Figure 4A block diagram 400 illustrates a device 405 supporting technologies for BWP handover mode according to one or more aspects of this disclosure. Device 405 may be an example of aspects of UE 115 as described herein. Device 405 may include a receiver 410, a transmitter 415, and a communications manager 420. Device 405 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0166] Receiver 410 may provide components for receiving information such as packets, user data, control information, or any combination thereof, associated with various information channels (e.g., control channels, data channels, and information channels related to the technology used for BWP handover modes). The information may be transmitted to other components of device 405. Receiver 410 may utilize a single antenna or a collection of multiple antennas.

[0167] Transmitter 415 may provide components for transmitting signals generated by other components of device 405. For example, transmitter 415 may transmit information such as packets, user data, control information, or any combination thereof, associated with various information channels (e.g., control channels, data channels, and information channels related to the technology used for BWP handover modes). In some examples, transmitter 415 may be co-located with receiver 410 in a transceiver module. Transmitter 415 may utilize a single antenna or a collection of multiple antennas.

[0168] The communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or various components thereof, may be examples of components used to perform various aspects of the techniques for BWP switching modes as described herein. For example, the communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or components thereof, may support methods for performing one or more functions described herein.

[0169] In some examples, the communication manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be implemented in hardware (e.g., in communication management circuitry). The hardware may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, configured or otherwise supporting components for performing the functions described herein. In some examples, the processor and memory coupled to the processor may be configured to perform one or more functions described herein (e.g., by executing instructions stored in memory by the processor).

[0170] Additionally or alternatively, in some examples, the communication manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be performed by any combination of a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or these or other programmable logic devices (e.g., components configured or otherwise supported for performing the functions described in this disclosure).

[0171] In some examples, the communication manager 420 may be configured to use or otherwise cooperate with the receiver 410, the transmitter 415, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, the communication manager 420 may receive information from the receiver 410, send information to the transmitter 415, or combine with the receiver 410, the transmitter 415, or both to receive information, send information, or perform various other operations as described herein.

[0172] According to the examples disclosed herein, the communication manager 420 may support wireless communication at a first device in a wireless communication network. For example, the communication manager 420 may be configured or otherwise support components for receiving a BWP switching mode configuration from a second device in the wireless communication network for wireless communication performed at the first device, the BWP switching mode including at least a first BWP and a second BWP different from the first BWP. The communication manager 420 may be configured or otherwise support components for transmitting a first transmission to one or more devices in the wireless communication network during a first time interval and according to the first BWP. The communication manager 420 may be configured or otherwise support components for transmitting a second transmission to one or more devices in the wireless communication network during a second time interval different from the first time interval and according to the second BWP.

[0173] By including or configuring the communication manager 420 according to the examples described herein, device 405 (e.g., a processor that controls or is otherwise coupled to receiver 410, transmitter 415, communication manager 420, or a combination thereof) can support techniques for configuring a BWP handover mode for UE 115, which can be used for wireless communication at UE 115. In the context of sidelink communication, the techniques described herein enable UE 115 to be configured with multiple BWPs within a BWP handover mode, thereby reducing the amount of control signaling from the network for configuring BWPs for sidelink communication. Therefore, by enabling UE 115 to be configured with a BWP handover mode including multiple BWPs, the techniques described herein can reduce control signaling overhead and improve resource utilization within the wireless communication system.

[0174] Figure 5 A block diagram 500 of a device 505 supporting a technology for BWP handover mode according to one or more aspects of this disclosure is shown. Device 505 may be an example of aspects of device 405 or UE 115 as described herein. Device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. Device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0175] Receiver 510 may provide components for receiving information such as packets, user data, control information, or any combination thereof, associated with various information channels (e.g., control channels, data channels, and information channels related to the technology used for BWP handover modes). The information may be transmitted to other components of device 505. Receiver 510 may utilize a single antenna or a collection of multiple antennas.

[0176] Transmitter 515 may provide components for transmitting signals generated by other components of device 505. For example, transmitter 515 may transmit information such as packets, user data, control information, or any combination thereof, associated with various information channels (e.g., control channels, data channels, and information channels related to the technology used for BWP handover modes).

[0177] Device 505 or its various components may be examples of parts used to perform various aspects of the techniques for BWP switching modes as described herein. For example, communication manager 520 may include configuring receiver manager 525, transmitter manager 530, or any combination thereof. Communication manager 520 may be examples of various aspects of communication manager 420 as described herein. In some examples, communication manager 520 or its various components may be configured to use or otherwise cooperate with receiver 510, transmitter 515, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, communication manager 520 may receive information from receiver 510, send information to transmitter 515, or combine with receiver 510, transmitter 515, or both to receive information, send information, or perform various other operations as described herein.

Transmission manager 530 may be configured or otherwise supported to support components for transmitting a second transmission to one or more devices in the wireless communication network during a second time interval different from the first time interval and according to the second BWP.

[0179] Figure 6 A block diagram 600 illustrates a communication manager 620 supporting techniques for BWP handover mode according to one or more aspects of this disclosure. The communication manager 620 may be an example of aspects of the communication manager 420, communication manager 520, or both as described herein. The communication manager 620 or its various components may be examples of parts for performing aspects of the techniques for BWP handover mode as described herein. For example, the communication manager 620 may include a configuration receiver manager 625, a transmitter manager 630, a PDSCH receiver manager 635, a BWP manager 640, a DCI receiver manager 645, an RRC receiver manager 650, or any combination thereof. Each of these components may communicate with each other directly or indirectly (e.g., via one or more buses).

[0180] According to the examples disclosed herein, the communication manager 620 may support wireless communication at a first device in a wireless communication network. The configuration receiver manager 625 may be configured or otherwise supported to support components for receiving configurations of a BWP switching mode for wireless communication performed at the first device from a second device in the wireless communication network, the BWP switching mode including at least a first BWP and a second BWP different from the first BWP. The transmission manager 630 may be configured or otherwise supported to support components for transmitting a first transmission to one or more devices in the wireless communication network during a first time interval and according to the first BWP. In some examples, the transmission manager 630 may be configured or otherwise supported to support components for transmitting a second transmission to one or more devices in the wireless communication network during a second time interval different from the first time interval and according to the second BWP.

[0181] In some examples, the PDSCH receive manager 635 may be configured or otherwise supported to include components for receiving PDSCH transmissions from a second device, including a configuration of a BWP handover mode, wherein sending a first transmission, a second transmission, or both is based on receiving a PDSCH transmission. In some examples, the PDSCH receive manager 635 may be configured or otherwise supported to include components for receiving a set of parameters associated with a BWP handover mode via a PDSCH transmission, wherein the first transmission, the second transmission, or both are sent according to the parameter set. In some examples, the PDSCH transmission includes RRC messages, MAC-CE messages, or both.

[0182] In some examples, the DCI receiver manager 645 may be configured or otherwise support components for receiving DCI messages from a second device, the DCI messages including indications of at least one parameter different from the parameter set, wherein a first transmission, a second transmission, or both are sent according to at least one parameter. In some examples, the DCI receiver manager 645 may be configured or otherwise support components for receiving DCI messages from a second device, the DCI messages including indications to the first device to perform wireless communication according to a BWP handover mode, wherein sending a first transmission, a second transmission, or both is based on receiving a DCI message.
