Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communication systems, and more particularly, to dormant bandwidth part (BWP) configurations that may be used for full - duplex operation.

[0004] Description of Related Art

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. A wireless multi - access communication system may include several base stations or network access nodes, each of which simultaneously supports the communication of multiple communication devices, which may also be referred to as user equipment (UE). These systems may be capable of supporting communication with multiple UEs by sharing available system resources such as time, frequency, and power. Examples of such multi - access systems include fourth - generation (4G) systems (such as Long - Term Evolution (LTE) systems, LTE - Advanced (LTE - A) systems, or LTE - A Pro systems), and fifth - generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems may employ various techniques, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT - S - OFDM).

[0006] A wireless communication system may include one or more devices configured for full-duplex communication, such as sub-band full-duplex communication. In full-duplex communication, a first antenna set of a device (such as a UE or a base station) is configured for downlink communication, and a second antenna set is configured for uplink communication. Interference may be generated by transmissions from one or more other devices (such as one or more base stations or UEs), or from self-interference. For example, in the case where the device is a UE, uplink communication performed by the UE may interfere with downlink communication from the base station, or in the case where the device is a base station, downlink communication performed by the base station may interfere with uplink communication from the UE. To mitigate self-interference, the UE may use a bandwidth less than the entire bandwidth of a bandwidth part (BWP), such as an uplink (UL) BWP or a downlink (DL) BWP. For example, the BWP may be configured to include a resource bandwidth (RBW) of a sub-band that includes the UL BWP or the DL BWP, which achieves an increase in the amount of separation between downlink and uplink communication. By increasing the amount of separation between downlink and uplink communication, the amount of leakage between downlink and uplink communication can be reduced, thereby mitigating or reducing self-interference.

[0007] A base station of a wireless communication system may include or operate a primary cell (Pcell) that provides a primary access link for serving each of one or more UEs. The same or a different base station in the wireless communication system may include or operate a secondary cell (Scell) that may operate on a secondary frequency and may be configured to be available for providing additional communication resources once a radio resource control (RRC) connection is established. The Scell may transition between a dormant state and a non-dormant state. When operating in the dormant state, the Scell may be associated with a dormant BWP in which various operations are restricted or subject to one or more constraints. For example, in the dormant BWP, the Scell does not transmit PDCCH or PDSCH and does not expect to receive PUCCH or PUSCH. The UE is correspondingly configured for the dormant BWP based on the restrictions or constraints. For example, the UE does not expect to receive PDCCH or PDSCH in the dormant BWP and does not transmit PUCCH or PUSCH in the dormant BWP. Such a configuration may enable the UE to achieve power savings when the Scell is in the dormant state.

[0008] When a UE is configured for a dormant BWP, the UE cannot determine self-interference for full-duplex operation because the UE does not transmit any signals within the dormant BWP. However, when configured for a dormant BWP, the UE can still receive downlink reference signals from the Scell in the dormant BWP and report the channel quality of the Scell to the Pcell. Additionally, when configured for a dormant BWP, the UE switches from the dormant BWP to a non-dormant BWP so that the UE can transmit a PUCCH or a PUSCH, or receive a PDCCH or a PDSCH. However, the handover operation may require a significant time duration due to reconfiguration of one or more antennas of the UE. During such time when the UE is performing the handover operation, the UE may be unavailable for communication with the base station of the Scell or one or more other devices of the wireless communication system in both the dormant BWP and the non-dormant BWP, resulting in system inefficiency and latency.

[0046] Detailed Description

[0047] The various aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, one skilled in the art can appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. Additionally, the scope of the present disclosure is intended to cover such apparatus or methods practiced using other structures, functionality, or a combination of structures and functionality that supplement or are additional to the various aspects of the present disclosure set forth herein. Any aspect of the present disclosure disclosed herein may be implemented by one or more elements of a claim.

[0048] The present disclosure provides systems, apparatuses, methods, and computer-readable media that support a dormant downlink bandwidth part (BWP) configuration that can be used for full-duplex operation. The dormant downlink BWP is associated with a secondary cell in which a user equipment (UE) does not routinely need to monitor the physical downlink control channel (e.g., PDCCH). In various aspects, a UE in full-duplex mode can receive a downlink signal from the secondary cell in the dormant downlink BWP in one or more symbols and transmit an uplink signal to the primary cell or the secondary cell in the uplink BWP in at least one of the same one or more symbols, which enables the UE to monitor or measure to determine self-interference.

[0049] In some implementations, a UE configured for a dormant downlink BWP can be further configured with one of a plurality of possible resource bandwidths (RBWs) that can be configured in the dormant downlink BWP. Each of the plurality of RBWs can be associated with a particular bandwidth segment within the dormant BWP and a set of one or more operating constraints. In some examples, two or more RBWs within the dormant BWP can be associated with different bandwidth sizes, different bandwidth positions, or different sets of operating constraints. In such examples or other examples, two or more RBWs can share a bandwidth size or position but can be associated with different sets of operating constraints. In these or yet other examples, two or more RBWs can share a common set of operating constraints but can differ in bandwidth size or position. For example, the plurality of RBWs can include one or more dormant RBWs in which the UE does not need to monitor the PDCCH. The plurality of RBWs can additionally include one or more non-dormant RBWs in which the UE can be configured to monitor the PDCCH even though they are within the dormant BWP. In some other examples, the plurality of RBWs can include one or more downlink dormant RBWs in which the UE does not need to monitor the PDCCH and in at least one uplink dormant RBW in which the UE is configured to transmit an uplink reference signal, such as an SRS.

[0050] Certain implementations of the subject matter described in this disclosure can achieve one or more of the following potential advantages. By transmitting an uplink signal to a primary cell or a secondary cell in an uplink BWP and concurrently receiving a downlink signal from the secondary cell in a dormant downlink BWP, a UE can monitor or measure one or more signal characteristics to determine interference, such as the amount of self-interference. Based on the determined interference, the UE can initiate actions to mitigate the interference. Additionally, the UE can be configured with different RBWs within the dormant BWP depending on various channel conditions, operating modes, time periods, or RRC criteria, each RBW having a different size, location, or associated operating constraints. By configuring the UE with different RBWs within the dormant BWP, flexibility and customization of the system, device, and resources can be provided to improve the operating efficiency of the UE or the wireless communication system, or to reduce service latency and interruptions. Additionally, switching between different RBWs of the same dormant downlink BWP can be performed faster than switching between different BWPs, which can further provide flexibility and customization, improve operating efficiency, or reduce service latency and interruptions.

[0051] Two or more wireless communication systems, also referred to as wireless communication networks, can be configured to provide or participate in authorized shared access between the two or more wireless communication systems. In various implementations, techniques and devices can be used in wireless communication networks such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, fifth-generation (5G) or new radio (NR) networks (sometimes referred to as "5G NR" networks, systems, or devices), and other communication networks. As described herein, the terms "network" and "system" can be used interchangeably.

[0052] CDMA networks can implement radio technologies such as universal terrestrial radio access (UTRA), cdma2000, etc. UTRA includes wideband CDMA (W-CDMA) and low chip rate (LCR). CDMA2000 covers the IS-2000, IS-95, and IS-856 standards.

[0053] TDMA networks can implement radio technologies such as Global System for Mobile Communications (GSM). 3GPP defines the standards for the GSM EDGE (Enhanced Data Rate for GSM Evolution) Radio Access Network (RAN) (also denoted as GERAN). GERAN is the radio component of GSM or GSM EDGE, together with the network that connects base stations (e.g., Ater and Abis interfaces, etc.) to base station controllers (e.g., A interface, etc.). The radio access network represents the component of the GSM network through which telephone calls and packet data are routed from the Public Switched Telephone Network (PSTN) and the Internet to the subscriber handset (also known as the user terminal or user equipment (UE)) and from the subscriber handset to the PSTN and the Internet. The network of a mobile phone operator may include one or more GERANs, which may be coupled to the UTRAN in the case of a UMTS / GSM network. Additionally, the operator network may include one or more LTE networks, or one or more other networks. Various different network types may use different Radio Access Technologies (RATs) and Radio Access Networks (RANs).

[0054] OFDMA networks can implement radio technologies such as evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM, etc. UTRA, E-UTRA, and GSM are part of the Universal Mobile Telecommunications System (UMTS). Specifically, Long Term Evolution (LTE) is a UMTS version that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents provided by an organization called the "3rd Generation Partnership Project" (3GPP), while cdma2000 is described in documents from an organization called the "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies and standards are known or under development. For example, 3GPP is a cooperation between telecommunications association groups that aims to define globally applicable third-generation (3G) mobile phone specifications. 3GPP Long Term Evolution (LTE) is a 3GPP project that aims to improve the Universal Mobile Telecommunications System (UMTS) mobile phone standard. 3GPP can define the specifications for next-generation mobile networks, mobile systems, and mobile devices. Certain aspects of the present disclosure may be described with reference to LTE, 4G, 5G, or NR technologies; however, the description is not intended to be limited to a particular technology or application, and one or more aspects described with reference to one technology may be understood to apply to another technology. In fact, one or more aspects of the present disclosure relate to shared access to the radio spectrum between networks using different radio access technologies or radio air interfaces.

[0055] The 5G network conceives various deployments, various spectrums, and various services and devices that can be realized using a unified OFDM-based air interface. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further enhancements to LTE and LTE-A are also considered. 5G NR will be able to scale to provide coverage for the following: (1) Massive Internet of Things (IoT) with ultra-high density (such as approximately 1M nodes / km 2 ), ultra-low complexity (such as approximately dozens of bits / second), ultra-low energy (such as approximately 10+ years of battery life), and deep coverage capable of reaching challenging locations; (2) Mission-critical control including users with strong security (to protect sensitive personal, financial, or confidential information), ultra-high reliability (such as approximately 99.9999% reliability), ultra-low latency (such as approximately 1 millisecond (ms)), and a wide range of mobility or lack of mobility; and (3) Enhanced mobile broadband, which includes extremely high capacity (such as approximately 10 Tbps / km 2 ), extreme data rates (such as multi-Gbps rates, 100+ Mbps user experience rates), and deep cognition with advanced discovery and optimization.

[0056] 5G NR devices, networks, and systems can be implemented to use optimized OFDM-based waveform characteristics. These characteristics may include: scalable parameter design and transmission time interval (TTI); a common, flexible framework to efficiently multiplex services and features using dynamic low-latency time-division duplex (TDD) / frequency-division duplex (FDD) designs; and advanced radio technologies such as massive multiple-input multiple-output (MIMO), robust millimeter-wave (mmWave) transmission, advanced channel coding, and device-centric mobility. The scalability of parameter design (and the scaling of subcarrier spacing) in 5G NR can efficiently address operating diverse services across diverse spectrums and diverse deployments. For example, in various outdoor and macro-coverage deployments implemented with less than 3 GHz FDD or TDD, the subcarrier spacing can occur at 15 kHz, for example, over bandwidths of 1, 5, 10, 20 MHz, etc. For various other outdoor and small cell coverage deployments with TDD greater than 3 GHz, the subcarrier spacing can occur at 30 kHz over 80 or 100 MHz bandwidths. For various other indoor broadband implementations, by using TDD in the unlicensed part of the 5 GHz band, the subcarrier spacing can occur at 60 kHz over 160 MHz bandwidths. Finally, for various deployments transmitting with the mmWave component at 28 GHz TDD, the subcarrier spacing can occur at 120 kHz over 500 MHz bandwidths.

[0057] The scalable parameter design of 5G NR enables scalable TTIs to meet various latency and Quality of Service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectral efficiency. The efficient multiplexing of long and short TTIs allows transmissions to start at symbol boundaries. 5G NR also contemplates a self - contained integrated subframe design with uplink or downlink scheduling information, data, and acknowledgments in the same subframe. The self - contained integrated subframe supports communication in unlicensed or contention - based shared spectrum, supports adaptive uplink or downlink that can be flexibly configured on a per - cell basis to dynamically switch between uplink and downlink to meet current traffic needs.

[0058] For clarity, certain aspects of the various devices and techniques may be described below with reference to example 5G NR implementations or in a 5G - centric manner, and 5G terminology may be used as illustrative examples in the following sections of the description; however, the description is not intended to be limited to 5G applications.

[0059] Furthermore, it should be understood that in operation, a wireless communication network adapted according to the concepts herein can operate with any combination of licensed or unlicensed spectrum depending on load and availability. Accordingly, it will be apparent to those of ordinary skill in the art that the systems, devices, and methods described herein can be applied to other communication systems and applications different from the specific examples provided.

[0060] Figure 1 is a block diagram illustrating details of an example wireless communication system. The wireless communication system may include a wireless network 100. For example, the wireless network 100 may include a 5G wireless network. As will be appreciated by those skilled in the art, Figure 1 the various components that appear in [the figure] are likely to have relevant counterparts in other network arrangements, including, for example, cellular network arrangements and non - cellular network arrangements such as device - to - device, peer - to - peer, or ad - hoc network arrangements, etc.

[0061] Figure 1The wireless network 100 described in the text includes several base stations 105 and other network entities. A base station can be a station that communicates with a UE and can be referred to as an evolved Node B (eNB), a next-generation eNB (gNB), an access point, etc. Each base station 105 can provide communication coverage for a specific geographical area. In 3GPP, the term "cell" can refer to such a specific geographical coverage area of a base station or the base station subsystem serving the coverage area, depending on the context in which the term is used. In the implementation of the wireless network 100 herein, the base stations 105 can be associated with the same operator or different operators, such as the wireless network 100 can include multiple operator wireless networks. Additionally, in the implementation of the wireless network 100 herein, the base stations 105 can use one or more frequencies in the same frequency as adjacent cells (such as one or more frequency bands in licensed spectrum, unlicensed spectrum, or a combination thereof) to provide wireless communication. In some examples, an individual base station 105 or UE 115 can be operated by more than one network operation entity. In some other examples, each base station 105 and UE 115 can be operated by a single network operation entity.

[0062] A base station can provide communication coverage for a macro cell or a small cell (such as a pico cell or a femto cell), or other types of cells. A macro cell generally covers a relatively large geographical area (such as a radius of several kilometers) and can allow unrestricted access by UEs having a service subscription with the network provider. A small cell (such as a pico cell) generally covers a relatively small geographical area and can allow unrestricted access by UEs having a service subscription with the network provider. A small cell (such as a femto cell) generally also covers a relatively small geographical area (such as a residence), and in addition to unrestricted access, it can also be accessed restrictively by UEs associated with the femto cell (such as UEs in a Closed Subscriber Group (CSG), UEs of users in the residence, etc.). The base station of a macro cell can be referred to as a macro base station. The base station of a small cell can be referred to as a small cell base station, a pico base station, a femto base station, or a home base station. In Figure 1 the example shown, base stations 105d and 105e are conventional macro base stations, while base stations 105a - 105c are macro base stations enabled with one of 3-dimensional (3D), full-dimensional (FD), or massive MIMO. Base stations 105a - 105c utilize their higher-dimensional MIMO capabilities to use 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station, which can be a home node or a portable access point. A base station can support one or more cells, such as two cells, three cells, four cells, etc.

[0063] The wireless network 100 may support synchronous or asynchronous operations. For synchronous operations, each base station may have a similar frame timing, and transmissions from different base stations may be approximately aligned in time. For asynchronous operations, each base station may have a different frame timing, and transmissions from different base stations may not be aligned in time. In some scenarios, the network may be implemented or configured to handle dynamic switching between synchronous and asynchronous operations.

[0064] UEs 115 are dispersed throughout the wireless network 100, and each UE may be stationary or mobile. It should be appreciated that although mobile devices are typically referred to as user equipment (UE) in the standards and specifications promulgated by 3GPP, such devices may additionally or alternatively be referred to by those skilled in the art as mobile stations (MS), subscriber stations, mobile units, subscriber units, radio units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals (AT), mobile terminals, wireless terminals, remote terminals, handsets, terminals, user agents, mobile clients, clients, or some other suitable term. Within this document, a "mobile" device or UE need not have mobility capabilities and may be stationary. Some non-limiting examples of mobile devices may include implementations of one or more of the UEs 115, including mobile stations, cellular telephones (cell phones), smart phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, laptop devices, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, and personal digital assistants (PDAs). Mobile devices may additionally be "Internet of Things" (IoT) or "Internet of Everything" (IoE) devices, such as automobiles or other transportation vehicles, satellite radios, global positioning system (GPS) devices, logistics controllers, drones, multi-axis aircraft, quadcopters, smart energy or security devices, solar panels or solar cell arrays, city lighting, water or other infrastructure; industrial automation and enterprise equipment; consumer and wearable devices, such as glasses, wearable cameras, smart watches, health or fitness trackers, mammalian implantable devices, posture tracking devices, medical devices, digital audio players (such as MP3 players), cameras, game consoles, etc.; and digital home or smart home devices, such as home audio, video, and multimedia devices, appliances, sensors, vending machines, smart lighting, home security systems, smart meters, etc. In one aspect, a UE may be a device that includes a universal integrated circuit card (UICC). In another aspect, a UE may be a device that does not include a UICC. In some aspects, a UE that does not include a UICC may be referred to as an IoE device. Figure 1The UEs 115a - 115d described in the context are examples of mobile smart phone type devices accessing the wireless network 100. The UE can be a machine specifically configured for connected communication, including machine type communication (MTC), enhanced MTC (eMTC), narrowband IoT (NB - IoT), etc.). Figure 1 The UEs 115e - 115k described in the context are examples of various machines configured for communication accessing the 5G network 100.

[0065] A mobile device such as UE 115 may be capable of communicating with any type of base station, whether macro base station, pico base station, femto base station, relay, etc. In Figure 1 the context, the communication link (represented as a lightning bolt) indicates the wireless transmission between the UE and the serving base station (the serving base station is the base station designated to serve the UE on the downlink or uplink), or the desired transmission between base stations, and the backhaul transmission between base stations. The backhaul communication between the base stations of the wireless network 100 can occur using wired and / or wireless communication links.

[0066] In the operation of the 5G network 100, the base stations 105a - 105c use 3D beamforming and coordinated spatial techniques such as coordinated multi - point (CoMP) or multi - connectivity to serve the UEs 115a and 115b. The macro base station 105d performs backhaul communication with the base stations 105a - 105c and the small cell base station 105f. The macro base station 105d also transmits multicast services subscribed to and received by the UEs 115c and 115d. Such multicast services may include mobile TV or streaming video, or may include other services for providing community information (such as weather emergencies or alerts, such as Amber alerts or Gray alerts).

[0067] Each implemented wireless network 100 supports mission-critical communications with ultra-reliable and redundant links for mission-critical devices such as UE 115e, which is a drone. The redundant communication links with UE 115e include those from macro base stations 105d and 105e, as well as small cell base station 105f. Other machine type devices such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device) can communicate directly with base stations (such as small cell base station 105f and macro base station 105e) via wireless network 100, or communicate via wireless network 100 in a multi-hop configuration by communicating with another user equipment that relays its information to the network (such as UE 115f communicating temperature measurement information to smart meter UE 115g, and the temperature measurement information being reported to the network via small cell base station 105f). The 5G network 100 can provide additional network efficiency via dynamic low-latency TDD or FDD communications (such as in a vehicle-to-vehicle (V2V) mesh network between UEs 115i - 115k communicating with macro base station 105e).

[0068] Figure 2 is a block diagram conceptually illustrating an example design of base station 105 and UE 115. Base station 105 and UE 115 can be Figure 1 one of each base station and one of each UE in. For a restricted association scenario (as mentioned above), base station 105 can be Figure 1 small cell base station 105f in, and UE 115 can be UE 115c or 115d operating in the service area of base station 105f. For access to small cell base station 105f, UE 115 will be included in the list of accessible UEs of small cell base station 105f. Additionally, base station 105 can be some other type of base station. As Figure 2 shown in, base station 105 can be equipped with antennas 234a to 234t, and UE 115 can be equipped with antennas 252a to 252r for facilitating wireless communication.

[0069] At base station 105, transmit processor 220 may receive data from data source 212 and control information from controller 240. The control information may be used for Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid ARQ (Automatic Repeat reQuest) Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Enhanced Physical Downlink Control Channel (EPDCCH), or Machine-Type Communication Physical Downlink Control Channel (MPDCCH), etc. The data may be used for Physical Downlink Shared Channel (PDSCH), etc. Transmit processor 220 may process (such as encoding and symbol mapping) the data and control information to obtain data symbols and control symbols respectively. Additionally, transmit processor 220 may generate reference symbols, such as reference symbols for Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS), and cell-specific reference signals. Transmit (TX) Multiple-Input Multiple-Output (MIMO) processor 230 may perform spatial processing on the data symbols, control symbols, or reference symbols when applicable, and may provide the output symbol streams to modulators (MOD) 232a through 232t. For example, the spatial processing performed on the data symbols, control symbols, or reference symbols may include precoding. Each modulator 232 may process the corresponding output symbol stream (such as for Orthogonal Frequency Division Multiplexing (OFDM), etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process the output sample stream to obtain a downlink signal. For example, to process the output sample stream, each modulator 232 may convert to analog, amplify, filter, and up-convert the output sample stream to obtain a downlink signal. The downlink signals from modulators 232a through 232t may be transmitted via antennas 234a through 234t respectively.

[0070] At User Equipment (UE) 115, antennas 252a through 252r may receive the downlink signals from base station 105 and may provide the received signals to demodulators (DEMOD) 254a through 254r respectively. Each demodulator 254 may condition the respective received signal to obtain input samples. For example, to condition the respective received signal, each demodulator 254 may filter, amplify, down-convert, and digitize the respective received signal to obtain input samples. Each demodulator 254 may further process the input samples (such as for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain the received symbols from demodulators 254a through 254r, perform MIMO detection on these received symbols when applicable, and provide detected symbols. Receive processor 258 may process these detected symbols, provide the decoded data for UE 115 to data sink 260, and provide the decoded control information to controller 280. For example, to process these detected symbols, receive processor 258 may demodulate, de-interleave, and decode these detected symbols.

[0071] On the uplink, at the UE 115, the transmit processor 264 may receive and process data from the data source 262 (such as data for the physical uplink shared channel (PUSCH)) and control information from the controller 280 (such as control information for the physical uplink control channel (PUCCH)). Additionally, the transmit processor 264 may generate reference symbols for reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 when applicable, further processed by the modulators 254a to 254r (such as for SC-FDM, etc.), and transmitted to the base station 105. At the base station 105, the uplink signal from the UE 115 may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 115. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller 240.

[0072] The controllers 240 and 280 may direct operations at the base station 105 and the UE 115, respectively. The controller 240 or other processors and modules at the base station 105, or the controller 280 or other processors and modules at the UE 115, may execute or direct the execution of various processes for the techniques described herein to, for example, execute or direct Figure 13 and 15 the execution illustrated in, or for other processes for the techniques described herein. The memories 242 and 282 may store data and program codes for the base station 105 and the UE 115, respectively. The scheduler 244 may schedule the UE for data transmission on the downlink or uplink.

[0073] In some cases, the UE 115 and the base station 105 may operate in a shared radio frequency spectrum band, which may include licensed or unlicensed (such as contention-based) spectrum. In the unlicensed frequency portion of the shared radio frequency spectrum band, the UE 115 or the base station 105 may conventionally perform a medium sensing procedure to contend for access to the spectrum. For example, the UE 115 or the base station 105 may perform a listen-before-talk or listen-before-transmit (LBT) procedure (such as a clear channel assessment (CCA)) before communication to determine whether the shared channel is available. The CCA may include an energy detection procedure for determining whether there is any other active transmission. For example, the device may infer that a change in the received signal strength indicator (RSSI) of a power meter indicates that the channel is occupied. Specifically, signal power concentrated in a specific bandwidth and exceeding a predetermined noise floor may indicate another wireless transmitter. In some implementations, the CCA may include the detection of a specific sequence indicating channel usage. For example, another device may transmit a specific preamble before transmitting a data sequence. In some cases, the LBT procedure may include a wireless node adjusting its own backoff window based on the amount of energy detected on the channel or the acknowledgment or negative acknowledgment (ACK or NACK) feedback for its own transmitted packets as an agent for conflicts.

[0074] Figure 3A , 3B and 3C are diagrams illustrating examples of wireless communication systems supporting full-duplex communication modes according to some aspects. The wireless communication system includes base stations 105d and 105e and UEs 115a and 115b.

[0075] For full-duplex operation, a device typically divides resources (such as antennas of an antenna array) into uplink resources and downlink resources that can operate simultaneously. For example, if the device is a base station, a first portion of the resources may be configured as downlink resources configured to transmit downlink signals and a second portion of the resources may be configured as uplink resources configured to receive uplink signals. In this configuration, the transmission of the downlink signal may cause interference to the uplink signal received concurrently with the transmission of the downlink signal. There may be other interferences regarding downlink signals and uplink signals associated with other base stations or UEs. Alternatively, if the device is a UE, a first portion of the resources may be configured as uplink resources and a second portion of the resources may be configured as downlink resources. In this configuration, the transmission of the uplink signal may cause interference to the downlink signal received concurrently with the transmission of the uplink signal.

[0076] In Figure 3AIn the example shown, base station 115d is configured for full-duplex operation while UE 115a is configured for half-duplex operation. Base station 115d transmits a downlink signal 302 to UE 115a and receives an uplink signal 304 from UE 115a. Base station 314 generates self-interference from the downlink signal 302 to the uplink signal 304. Additionally, the communication from base station 105e causes interference 306 to base station 105d and interference 308 to UE 115a. The communication from UE 115b causes interference 310 to base station 105e and interference 312 to UE 115a.

[0077] In Figure 3B the example shown, base station 115d is configured for full-duplex operation while UE 115a is configured for full-duplex operation. UE 115 transmits an uplink signal 324 to base station 105d and receives a downlink signal 322 from base station 105d. UE 115a generates self-interference 334 from the uplink signal 324 to the downlink signal 322. Additionally, base station 105e transmits a downlink signal 326 to UE 115b. The communication from base station 105e may also cause interference 328 to UE 115a. The communication from UE 115b may also cause interference to UE 115a.

[0078] In Figure 3C the example shown, UE 115a is configured for full-duplex operation with multiple transmission points (multi-TRP). UE 115a transmits an uplink signal 344 to base station 105d and UE 115b receives a downlink 342 from base station 105e. UE 115a experiences self-interference 354 by interfering with one or more downlink signals for UE 115a based on the uplink signal 344. For example, the uplink signal 344 may interfere with the PDCCH from base station 105d or base station 105e to UE 115a.

[0079] Figure 4A is a diagram illustrating an example of in-band full-duplex (IBFD) communication and Figure 4B is a diagram illustrating an example of sub-band full-duplex communication. Refer to Figure 4A, the first illustration 410 illustrates a first example of IBFD and the second illustration 430 illustrates a second example of IBFD. A device configured for IBFD operation can perform transmission and reception operations at the same time and in a frequency resource. For example, the DL resource 414 and the UL resource 412 can share the same IBFD time / frequency resource, which can include a complete overlap of resources or a partial overlap of resources. In the example shown in the first illustration 410, a complete overlap of resources is shown, where the entirety of the UL resource 412 overlaps with a part of the DL resource 414 in both frequency and time. In the example shown in the second illustration 430, a partial overlap of resources is shown, where a part of the UL resource 432 overlaps with a part of the DL resource 434 in both frequency and time.

[0080] Figure 4B Figure 450 is an illustration that explains an example of sub-band full-duplex operation (also known as flexible duplex operation). In sub-band full-duplex operation, the uplink signal and the downlink signal communicate at the same time but on different frequency resources. As Figure 4B shown, the UL resource 452 overlaps with the DL resource 454 in time. For example, the UL resource and the DL resource 454 can overlap for at least one symbol or at least one time slot. Additionally, the DL resource 454 can be separated from the UL resource 452 in the frequency domain by a guard band 456. Although the guard band 456 exists between the DL resource 454 and the UL resource 452, the guard band 456 can be very small such that leakage still occurs between the downlink communication in the DL resource 454 and the uplink communication in the UL resource 452.

[0081] Figure 5 Figure 510 is an illustration that explains an example base station configured for sub-band full-duplex communication according to some aspects. A base station (such as base station 105d) includes hardware 502 that can be configured for full-duplex operation. For illustration purposes, the hardware 502 can include two panels, such as a first panel 504 and a second panel 506 for simultaneous transmission and reception operations. For example, the first panel 504 can be configured for transmission operations, and the second panel can be configured for reception operations. Figure 510 shows an example of simultaneous transmission and reception signals associated with the full-duplex operation of the base station. The transmission and reception signals exist within a bandwidth 511, where the edge portion 512 (of the bandwidth 511) is associated with the downlink signal, and the middle portion 514 (of the bandwidth 511) is associated with the uplink signal.

[0082] Illustration 520 shows an example of a representation of how full-duplex operation can be implemented by a base station in the frequency domain and the time domain. As shown in Illustration 520, four time slots 522, 524, 526, and 528 are shown in the time domain and are allocated for full-duplex operation. For illustration purposes, the first time slot 522 is allocated for downlink operation, the second time slot 524 and the third time slot 526 are each allocated such that the middle part is allocated for uplink operation and the two side parts are allocated for downlink operation, and the fourth time slot 528 is allocated for uplink operation. Accordingly, the first time slot 522, the second time slot 524, and the third time slot 526 can be used for downlink signals, and the second time slot 524, the third time slot 526, and the fourth time slot 528 can be used for uplink signals.

[0083] Illustration 530 shows an example of the configuration of the first panel 504 and the second panel 506 with respect to the four time slots 522, 524, 526, and 528 of Illustration 520. During the first time slot 522, the first panel 504 and the second panel 506 are configured for downlink operation. During the second time slot 524 and the third time slot 526, the first panel 504 is configured for downlink operation while the second panel 506 is configured for uplink operation. During the fourth time slot 528, the first panel 504 and the second panel 506 are configured for uplink operation.

[0084] Figure 6 is a block diagram illustrating an example of a BWP that can include one or more possible RBWs. In Figure 6 In Figure 5 the four time slots of Illustration 520 are shown with respect to the active BWP 650.

[0085] BWP 650 is associated with a continuous portion of the bandwidth of a downlink signal or an uplink signal that can be monitored by a UE, such as UE 115. For a UE, up to four BWPs can be configured for downlink operation, and up to four BWPs can be configured for uplink operation. However, only one BWP can be active for uplink operation at a given time, and only one BWP can be active for downlink operation at a given time. The UE is configured to switch between different BWPs, which can be time-consuming, resulting in latency or inefficiency in communication and negatively affecting the user experience. For example, the UE can switch between two different BWPs based on DCI, a bandwidth inactivity timer (Bwp-InactivityTimer), RRC signaling, or a MAC entity. For illustration, DCI can indicate a specific BWP to be activated. Additionally or alternatively, the bandwidth inactivity timer can be used to switch between downlink BWPs after a period of time has elapsed during which no downlink communication has been received from the serving cell. In some implementations, the bandwidth inactivity timer can include or correspond to the serving cell configured bandwidth inactivity time (ServingCellConfig.bwp-InactivityTimer).

[0086] When using BWPs that are continuous in frequency and have large switching times, problems may occur in full duplex such that uplink signals and downlink signals are not received or are subject to interference. Accordingly, BWP 650 can be configured as one of a plurality of possible RBWs such that the UE can monitor a portion of the bandwidth of BWP 650 and switch between RBWs, which has a shorter switching time than switching between BWPs.

[0087] Block diagram 660 illustrates an example of a BWP 650 configured with multiple possible RBWs. BWP 650 spans a bandwidth that may include or correspond to a set of one or more resource blocks (RBs). BWP 650 is configured with multiple possible RBWs, such as a first RBW 651 (RBW_1), a second RBW 652 (RBW_2), a third RBW 653 (RBW_3), and a fourth RBW 654 (RBW_4). Each of the multiple possible RBWs may be defined based on the initial RB of the RBW, the final RB of the RBW, the length of the RBW, or a combination thereof. Note that the length may wrap around from the end of the bandwidth to the start of the bandwidth. As an illustrative example, if the bandwidth of BWP 650 includes twelve RBs (RB0 - RB11), the first RBW 651 may have an initial RB of RB0, a final RB of RB11, and a length of 12; the second RBW 652 may have an initial RB of RB05, a final RB of RB11, and a length of 7; the third RBW 653 may have an initial RB of RB5, a final RB of RB2, and a length of 10; and the fourth RBW 654 may have an initial RB of RB0, a final RB of RB4, and a length of 5. Accordingly, as shown, each of the first RBW 651, the second RBW 652, and the fourth RBW 654 is continuous, and the third RBW 653 is discontinuous. Additionally or alternatively, an RBW may be defined as a bitmap of RBs. For example, if the value "1" indicates that the RBW includes the RB and the value "0" indicates that the RBW does not include the RB, the bitmap of the first RBW 651 may be "111111111111", the bitmap of the second RBW 652 may be "000001111111", the bitmap of the third RBW 653 may be "111001111111", and the bitmap of the fourth RBW 654 may be "111110000000".

[0088] Figure 7 is a state diagram that illustrates an example of a device state associated with operations in a dormant BWP. For example, the device may be a base station 105 operating in a secondary cell. The device may be configured to be in a deactivated state 710 or an activated state 720. The device may transition from the deactivated state 710 to the activated state 720 at 750 based on a MAC-CE (such as a MAC-CE received from a Pcell or a PScell). The device may transition from the activated state 720 to the deactivated state 710 at 752 based on a MAC-CE (such as a MAC-CE received from a Pcell or a PScell) or based on a timer (such as an sCellDeactivationTimer (secondary cell deactivation timer)).

[0089] When in the active state 720, the device can be in one of multiple sub - states or configurations. The multiple sub - states can include a dormant BWP 722 or a non - dormant BWP 724. During the non - dormant BWP 724, the device can perform normal operations without restricting one or more operations. Alternatively, the dormant BWP 722 can provide power savings compared to the non - dormant BWP 724. For example, during the dormant BWP 722, the operations of the device can be restricted such that one or more signals are not transmitted or received, such as PDCCH, PDSCH, PUCCH, or PUSCH.

[0090] The device can be configured to transition to or from the BWP 722 based on one or more signals received from the primary cell or the primary - secondary cell. For example, the one or more signals can include DCI or be associated with DCI, such as DCI format 0 - 1 / 1 - 1. By way of illustration, the device at 760 can transition from the dormant BWP 722 to the non - dormant BWP 724 based on a first DCI. The device at 762 can transition from the non - dormant BWP 724 to the dormant BWP 722 based on a second DCI. In some implementations, the device can transition between the non - dormant BWP 724 and the dormant BWP 722 during the active time based on DCI. Additionally or alternatively, the device can transition between the non - dormant BWP 724 and the dormant BWP 722 outside the active time based on a wake - up signal (WUS).

[0091] When the device is in the dormant BWP 722, a UE (such as UE 115) can also utilize the corresponding dormant BWP and can monitor the channels associated with the device. For example, the UE can monitor the channels to determine the quality of a secondary cell and report the quality of the secondary cell to the primary cell to notify the primary cell of the state of the dormant secondary cell. In some implementations, when the UE is configured for the dormant BWP, the UE can be able to determine the channel quality associated with the secondary cell but not communicate with the secondary cell (e.g., receive PDCCH or PDSCH, or transmit PUCCH or PUSCH). If the primary cell wishes the UE to utilize the secondary cell, the primary cell (or the primary - secondary cell) instructs the UE to use the non - dormant BWP, where the UE can resume normal operations, such as monitoring PDCCH or PDSCH, transmitting PUCCH or PUSCH, or a combination thereof. By way of illustration, the UE can monitor the PDCCH from the primary cell and receive a PDCCH indicating that the UE should switch to the non - dormant BWP for the Scell.

[0092] The present disclosure provides a system, apparatus, method, and computer-readable medium that support a dormant downlink BWP configuration that can be used for full-duplex operation. The dormant downlink BWP is associated with a secondary cell for which a UE does not routinely need to monitor the physical downlink control channel (e.g., PDCCH). In various aspects, a UE in full-duplex mode can receive downlink signals in a dormant downlink BWP in one or more symbols and transmit uplink signals in at least one same symbol of the one or more symbols in an uplink BWP, which enables the UE to monitor or measure to determine self-interference. In some implementations, a UE configured for a dormant downlink BWP can be further configured with one of a plurality of possible RBWs that can be configured in the dormant downlink BWP. Each of the plurality of RBWs can be associated with a specific bandwidth within the dormant BWP and a set of one or more operational constraints. In some examples, two or more RBWs within the dormant BWP can be associated with different bandwidth sizes, different bandwidth positions, and different sets of operational constraints. In such examples or other examples, two or more RBWs can share a bandwidth size or position but can be associated with different sets of operational constraints. In these or yet other examples, two or more RBWs can share a common set of operational constraints but can differ in bandwidth size or position. For example, the plurality of RBWs can include one or more dormant RBWs in which the UE does not need to monitor the PDCCH. The plurality of RBWs can additionally include one or more non-dormant RBWs in which the UE can be configured to monitor the PDCCH, although they are located within the dormant BWP. In some other examples, the plurality of RBWs can include one or more downlink dormant RBWs in which the UE does not need to monitor the PDCCH and at least one uplink dormant RBW.

[0093] Certain implementations of the subject matter described in this disclosure can achieve one or more of the following potential advantages. In some aspects, the present disclosure provides a configuration for a dormant downlink BWP, where a UE can concurrently receive downlink signals together with the transmission of uplink signals in an uplink BWP. By transmitting uplink signals concurrently with receiving downlink signals, the UE can monitor or measure one or more signal characteristics to determine interference, such as the amount of self-interference. Additionally, by configuring the UE with different RBWs within the dormant BWP depending on various channel conditions, operating modes, time periods, or RRC criteria, each RBW having a different size, location, or associated operating constraints, various aspects can provide system, device, and resource flexibility and customization, improve the operating efficiency of the UE or the wireless communication system, or reduce service latency and interruptions. Additionally, switching between different RBWs of the same dormant downlink BWP can be performed faster than switching between different BWPs, which can further provide flexibility and customization, improve operating efficiency, or reduce service latency and interruptions.

[0094] Figure 8 FIG. 800 is a block diagram of an example wireless communication system 800 that supports a dormant BWP configuration that can be used for full-duplex operation, according to some aspects. In some examples, the wireless communication system 800 can implement aspects of the wireless network 100. The wireless communication system 800 includes a UE 115, a base station 105, and a base station 860. Although one UE 115 and two base stations 105, 860 are illustrated, in some other implementations, the wireless communication system 800 generally can include multiple UEs 115 and can include more than two base stations 105, 860.

For example, one or more BWP configurations may include UL BWP, DL BWP, non-dormant BWP, dormant BWP, active BWP, non-active BWP, or a combination thereof, as illustrative non-limiting examples. Additionally or alternatively, one or more RBW configurations may include dormant RBW, non-dormant RBW, default dormant RBW, default non-dormant RBW, downlink dormant RBW, uplink dormant RBW, default downlink dormant RBW, default uplink dormant RBW, or a combination thereof, as illustrative non-limiting examples.

[0097] As shown, the BWP information includes a first BWP 806 and a second BWP 813. In some implementations, the first BWP 806 is a dormant BWP, and the second BWP 813 is a dormant BWP or a non-dormant BWP. The dormant BWP is associated with a secondary cell for which the UE 115 does not need to monitor the physical downlink control channel (such as, PDCCH 882). The first BWP 806 may include or indicate a dormant RBW 808, a non-dormant RBW 810, one or more operation constraints 812 (collectively referred to hereinafter as "operation constraints 812"), or a combination thereof. The operation constraints 812 may define operations for the first BWP 806, such as operations for the dormant RBW 808. The operation constraints 812 may receive downlink signals, transmit uplink signals, monitor SCI-RS, transmit sounding reference signals, measure the self-interference of the UE 115, measure cluster reflections, receive downlink reference signals, transmit uplink reference signals, perform measurements associated with full duplex, receive downlink channels, transmit uplink channels, or a combination thereof, as illustrative non-limiting examples.

[0098] Channel quality information 814 may include or indicate an amount of interference, such as self-interference of the UE 115 from the uplink to the downlink. The self-interference may include or correspond to self-interferences 334, 354. Additionally or alternatively, the channel quality information 814 may include or indicate downlink reference signal measurements. The mode information 815 includes settings or parameters of one or more modes, such as a half-duplex mode, a full-duplex mode, such as an IBFD mode or a sub-band full-duplex mode, or a combination thereof. Additionally or alternatively, the channel quality information 814 may include or indicate RRM measurements or RLM measurements. The RRM may be based on measurements of SSB or CSI-RS and may be reported with metrics such as reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-interference-plus-noise ratio (SINR). Similarly, for RLM, both SS block-based RLM and CSI-RS-based RLM may be supported.

[0099] The transmitter 816 is configured to transmit reference signals, control information, and data to one or more other devices, and the receiver 818 is configured to receive reference signals, synchronization signals, control information, and data from one or more other devices. For example, the transmitter 816 may transmit signaling, control information, and data to the base station 105, while the receiver 818 may receive signaling, control information, and data from the base station 105. In some implementations, the transmitter 816 and the receiver 818 may be integrated in one or more transceivers. Additionally or alternatively, the transmitter 816 or the receiver 818 may include or correspond to one or more components of the UE 115 described with reference to Figure 2 Those described. In some implementations, the transmitter 816 and the receiver 818 may be coupled to an antenna array, and the transmitter 816, the receiver 818, and the antenna array may be configured based on the BWP information 805. The timer 820 is configured to track or determine one or more time periods.

[0100] The base station 105 may be associated with or operate in a Pcell or a PScell. The base station 105 may include various components (such as structures, hardware components) for performing one or more functions described herein. For example, these components may include one or more processors 852 (collectively referred to hereinafter as "processor 852"), one or more memory devices 854 (collectively referred to hereinafter as "memory 854"), one or more transmitters 856 (collectively referred to hereinafter as "transmitter 856"), and one or more receivers 858 (collectively referred to hereinafter as "receiver 858"). The processor 852 may be configured to execute instructions stored in the memory 854 to perform the operations described herein. In some implementations, the processor 852 includes or corresponds to one or more of the receive processor 238, the transmit processor 220, and the controller 240, and the memory 854 includes or corresponds to the memory 242.

[0101] The transmitter 856 is configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 858 is configured to receive reference signals, control information, and data from one or more other devices. For example, the transmitter 856 may transmit signaling, control information, and data to the UE 115, while the receiver 858 may receive signaling, control information, and data from the UE 105. In some implementations, the transmitter 856 and the receiver 858 may be integrated in one or more transceivers. Additionally or alternatively, the transmitter 856 or the receiver 858 may include or correspond to one or more components of the base station 105 described with reference to Figure 2 one or more components of the base station 105 described with reference to

[0102] The base station 860 is associated with or operates in the Scell. The base station 860 may include various components (such as structures, hardware components) for performing one or more functions described herein. For example, these components may include one or more processors 862 (collectively referred to hereinafter as "processor 862"), one or more memory devices 864 (collectively referred to hereinafter as "memory 864"), one or more transmitters 866 (collectively referred to hereinafter as "transmitter 866"), and one or more receivers 868 (collectively referred to hereinafter as "receiver 868"). The processor 862 may be configured to execute instructions stored in the memory 864 to perform the operations described herein. In some implementations, the processor 862 includes or corresponds to one or more of the receiving processor 238, the transmitting processor 220, and the controller 240, and the memory 864 includes or corresponds to the memory 242.

[0103] The transmitter 866 is configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 868 is configured to receive reference signals, control information, and data from one or more other devices. For example, the transmitter 866 may transmit signaling, control information, and data to the UE 115, while the receiver 868 may receive signaling, control information, and data from the UE 105. In some implementations, the transmitter 866 and the receiver 868 may be integrated in one or more transceivers. Additionally or alternatively, the transmitter 866 or the receiver 868 may include or correspond to one or more components of the base station 105 described with reference to Figure 2 one or more components of the base station 105 described with reference to

[0104] In some implementations, the wireless communication system 800 implements a 5G New Radio (NR) network. For example, the wireless communication system 800 may include multiple 5G-capable UEs 115 and multiple 5G-capable base stations 105, such as UEs and base stations configured to operate according to a 5G NR network protocol (such as defined by 3GPP).

[0105] In some implementations, the base station 860 is associated with a secondary cell in full-duplex operation, such as sub-band full-duplex where uplink resources and downlink resources share time but are separated in frequency. The UE 115 can be configured to perform full-duplex operation concurrently with the base station 860 in an active state and in full-duplex mode. The UE 115 configured for a non-dormant BWP can support uplink channels, downlink channels, and transmit one or more signals, such as sounding reference signals. The UE 115 configured for a dormant BWP (such as a dormant downlink BWP) can be configured to operate according to one or more operating constraints and can be restricted or prohibited from performing other operations compared to a non-dormant BWP (such as a non-dormant downlink BWP). For example, the UE 115 configured for a dormant downlink BWP may not monitor the PDCCH 882. However, the UE 115 configured for a dormant downlink BWP can receive the RS 880 (such as a downlink RS). Additionally, the UE 115 can be configured for a non-dormant uplink BWP, where the UE 115 can transmit a reference signal (such as the SRS 876). The SRS 876, the RS 880, or both can enable the UE 115 to determine the amount of interference, such as the amount of self-interference from the uplink to the downlink, or to measure the channel quality for maintaining RRM or RLM. By way of illustration, the UE 115 can determine self-interference based on the SRS 876, the RS 880, or a combination thereof. Additionally or alternatively, the UE 115 can measure clutter reflections. In some implementations, the UE 115 can switch from full-duplex operation to half-duplex mode operation. For example, the UE 115 can switch to half-duplex operation based on the control message 872. By way of illustration, the control message 872 can include DCI, and the UE 115 can switch to half-duplex operation based on the received DCI. The control message 872 can be received from the primary cell or the primary-secondary cell, such as from the base station 105 operating in the primary cell or the primary-secondary cell. By switching to half-duplex operation, the UE 115 can save power compared to full-duplex operation.

[0106] In some implementations, a BWP (such as a dormant downlink BWP) is configured with multiple possible RBWs. For example, one or more RBWs can be defined by a configuration message 870 (such as an RRC message). A BWP (such as a dormant downlink BWP) having multiple possible RBWs can include or correspond to Figure 6 the BWP 650. Further examples of a BWP including multiple possible RBWs are further described herein at least with reference to Figures 9 - 12Description. At least one of a plurality of possible RBWs may be a dormant RBW. A dormant RBW may be defined as part or all of the bandwidth of a BWP in which UE 115 may operate according to one or more operation constraints. Compared with non-dormant RBWs, one or more of the operation constraints in an RBW may have the effect of providing one or more operation limitations. By way of illustration, the one or more operation constraints may be associated with DL RS reception, full duplex and self-interference related measurements, or DL channel reception, as illustrative non-limiting examples. In some implementations, the plurality of possible RBWs may also include non-dormant resource BWs. In some implementations, each of the plurality of possible RBWs corresponds to a respective set of one or more operation constraints, such as a set of one or more operations that UE 115 may perform, a set of one or more operations that UE 115 is prohibited from performing, or a combination thereof.

[0107] Figure 9 is an example of a dormant BWP 910 that may be used for downlink communication according to some aspects. BWP 910 (such as a dormant downlink BWP) may include or correspond to the first BWP 806. BWP 910 spans a bandwidth and includes a plurality of possible RBWs, such as a first RBW 951 (RBW_1), a second RBW 952 (RBW_2), a third RBW 953 (RBW_3), and a fourth RBW 954 (RBW_4). As shown, the second RBW 952 is a dormant RBW, and each of the first RBW 951, the third RBW 953, and the fourth RBW 954 is in a non-dormant RBW.

[0108] UE 115 may switch between using a dormant RBW and using a non-dormant RBW based on a handover message 874 received from a base station 105 (such as a base station 105 operating in a primary cell or a primary-secondary cell). For example, the handover message 874 may include DCI, and UE 115 may switch between using a dormant RBW and using a non-dormant RBW based on the received DCI. In some implementations, UE 115 may switch between using different RBWs periodically or based on an elapsed time period (such as a time period indicated in the DCI or an RRC message received from the base station 105).

[0109] In some implementations, a dormant downlink BWP may be configured with a plurality of possible dormant RBWs. By way of illustration, Figure 10This is an example of a dormant BWP 1010 that can be used for downlink communication according to some aspects. The BWP 1010 (such as a dormant downlink BWP) may include or correspond to the first BWP 806. The BWP 1010 spans a bandwidth and includes a plurality of possible RBWs, such as a first RBW 1051 (RBW_1), a second RBW 1052 (RBW_2), a third RBW 1053 (RBW_3), and a fourth RBW 1054 (RBW_4). As shown, each of the first RBW 1051 and the second RBW 1052 is a dormant RBW, and each of the third RBW 1053 and the fourth RBW 1054 is a non-dormant RBW.

[0110] In some implementations, each of the dormant RBWs may be configured with a set of one or more operating constraints, such as different operating limits. For example, if the dormant BWP includes three dormant RBWs, such as a first RBW_1, a second RBW_2, and a third RBW_3, each of the three dormant RBWs may include different limits or different operating constraints. For illustration, the first RBW_1 may be configured to only monitor CSI-RS, the second RBW may be configured to monitor CSI-RS and transmit SRS, and the third RBW_3 may be configured to measure self-interference or clutter reflection.

[0111] In some implementations, one or more of the plurality of possible RBWs may be designated as a default RBW. For example, the configuration message 870 or the bandwidth information included therein may indicate one or more default RBWs. For illustration, the plurality of possible RBWs may include a first dormant RBW and a second dormant RBW, and one of the first dormant RBW and the second dormant RBW may be indicated as the default dormant RBW. In the case where the handover message does not identify the BWP or the RBW, the default dormant RBW may be selected by the UE 115 based on the wake-up signal or based on the handover message. Additionally, the configuration message 870 may indicate the initial or default RBW to be used by the UE 115. For example, the configuration message 870 may indicate the default non-dormant RBW of the plurality of possible RBWs. In the case where the plurality of RBWs includes more than one non-dormant RBW and the UE 115 receives a handover message 874 that does not specify which non-dormant RBW to switch to or use, the default non-dormant RBW may be designated.

[0112] In some implementations, one or more of the plurality of possible RBWs may include a downlink dormant RBW, an uplink dormant RBW, or a combination thereof. The downlink dormant RBW may include or permit operational constraints for receiving downlink RSs (such as RS 880), measuring RRM, measuring RLM, or a combination thereof. The uplink dormant RBW may include or permit operational constraints for transmitting uplink reference signals (such as SRS 786), measuring interference (such as self-interference of UE 115), or a combination thereof. By way of illustration, Figure 11 is an example of a dormant BWP 1110 that may be used for either downlink or uplink communication according to some aspects. The BWP 1010 (such as a dormant downlink BWP) may include or correspond to the first BWP 806. The BWP 1110 spans a bandwidth and includes a plurality of possible RBWs, such as a first RBW 1051 (RBW_1), such as a downlink dormant RBW, and a second RBW 1052 (RBW_2), such as an uplink dormant RBW.

[0113] In some implementations, the configuration message 870 may be associated with a plurality of BWPs, each BWP including at least one dormant resource. For example, Figure 12 is an example showing two downlink BWPs that may be used for downlink communication according to some aspects. The plurality of BWPs includes a first BWP 1210 and a second BWP 1220. The first BWP 1210 spans a first bandwidth and includes a plurality of possible RBWs, such as a first RBW 1211 (RBW_1), a second RBW 1212 (RBW_2), a third RBW 1213 (RBW_3), and a fourth RBW 1214 (RBW_4). As shown, the first RBW 1211 of the first BWP 1210 is a dormant RBW. The second BWP 12210 spans a second bandwidth and includes a plurality of possible RBWs, such as a first RBW 1221 (RBW_1), a second RBW 1222 (RBW_2), a third RBW 1223 (RBW_3), and a fourth RBW 1224 (RBW_4). As shown, the second RBW 1220 of the second BWP 1220 is a dormant RBW. The first bandwidth and the second bandwidth may be the same bandwidth or different bandwidths, such as distinct or partially overlapping bandwidths. If the UE 115 is configured to use the second RBW 1212 (such as a non-dormant RBW) of the first BWP 1210 as an active BWP, the UE 115 may receive a handover message (such as the handover message 874) via the second RBW 1212. Based on the handover message 874, the UE 115 may switch to using the dormant RBW within the first BWP 1210 (such as the active BWP), or the UE 115 may switch to using the dormant resource BW within another BWP (such as the second BWP 1220).

[0114] During operation of the wireless communication system 800, the base station 105 may transmit a configuration message 870 (such as an RRC message) to the UE 115. The configuration message 870 may be associated with a dormant downlink BWP (such as the first BWP 806). For example, the configuration message 870 may include a configuration that defines the dormant downlink BWP. The dormant downlink BWP may be associated with one or more operating constraints including receiving downlink signals.

[0115] The UE 115 receives the configuration message 870 and determines one or more active BWPs, such as a dormant downlink BWP, an uplink BWP, or a combination thereof. The UE 115 configures the UE 115 for the one or more active BWPs. In some implementations, when the UE 115 is configured for the dormant downlink BWP, the UE 115 is configured in a full-duplex mode.

[0116] After configuring the UE 115 for the dormant downlink BWP, the UE 115 receives the RS 880 in the dormant downlink BWP. Additionally, the UE 115 may transmit a sounding reference signal SRS 876 in another BWP (such as an uplink BWP). Based on the RS 880, the SRS 876, or both, the UE 115 may determine channel quality information 814.

[0117] In some implementations, before or after receiving the configuration message 870, the UE 115 may receive a control message 872 from the base station 105. The control message 872 may include DCI to cause the UE to set the mode of the UE, such as being in a full-duplex mode or a half-duplex mode.

[0118] After transmitting the SRS 876 and receiving the RS 880, the UE 115 may receive one or more handover messages (such as the handover message 874). In some implementations, based on the first handover message, the UE 115 may identify a non-dormant downlink BWP (such as the second BWP 813). The UE 115 may configure the UE 115 for the non-dormant BWP. The UE 115 may receive a PDCCH 882 in the non-dormant BWP, transmit a PUCCH 878 in the uplink BWP, or a combination thereof. In some implementations, based on the second handover message, the UE 115 may switch from using a dormant RBW to using another RBW, such as another RBW of the dormant downlink BWP or an RBW of another BWP, such as an RBW of another dormant downlink BWP or an RBW of a non-dormant downlink BWP.

[0119] In some implementations, the UE 115 may periodically switch from using a dormant RBW to using another RBW. Additionally or alternatively, the UE 115 may switch from using a dormant RBW to using another RBW based on the expiration of a timer 820. For example, the UE 115 may determine the duration of a time period based on DCI or RRC messages received from a primary cell or a primary-secondary cell, and set the timer 820 based on the determined duration of the time period.

[0120] As described with reference to Figure 8 the present disclosure provides techniques for using a dormant downlink BWP. For example, the UE 115 may be configured for a dormant downlink BWP associated with a secondary cell for which the UE 115 does not need to monitor the physical downlink control channel. When configured in the dormant downlink BWP and in full-duplex mode, the UE 115 may receive a downlink signal in the dormant downlink BWP in one or more symbols, and receive an uplink signal in the uplink BWP in at least one of the one or more symbols. Based on the downlink signal, the uplink signal, or a combination thereof, the UE 115 may determine interference (such as the amount of self-interference). Additionally, the dormant downlink BWP may include a plurality of RBWs having at least one dormant RBW, which is associated with a corresponding set of one or more operating constraints of the UE 115. Different operating constraints of different RBWs may provide flexibility and customization for the system and the device. Additionally, switching the UE 115 between different RBWs of a BWP may be performed faster than switching between different BWPs. Accordingly, the use of a dormant BWP including a plurality of RBWs may improve the operating efficiency of the UE and reduce service latency and interruption.

[0121] Figure 13 is a flow diagram illustrating an example process 1300 that supports a dormant BWP configuration that may be used for full-duplex operation for downlink communication according to some aspects. The operations of process 1300 may be performed by a UE, such as the UE 115 described above with reference to Figure 1 、 2 、3A, 3B, 3C, and 8, or the UE 1600 described with reference to Figure 14 For example, the example operations (also referred to as "blocks") of process 1300 may enable the UE 400 to support a dormant BWP.

[0122] At block 1302, the UE receives one or more configurations for a dormant downlink BWP and an uplink BWP. The one or more configurations may include or correspond to BWP information 805. The dormant downlink BWP may be associated with a secondary cell for which the UE does not need to monitor the physical downlink control channel. The secondary cell may be associated with the base station 860. The dormant downlink BWP and the uplink BWP may include or correspond to the first BWP 806 or the second BWP 813. In some implementations, the uplink BWP is associated with the secondary cell.

[0123] At block 1304, the UE receives a downlink signal in the dormant downlink BWP in one or more symbols while in full-duplex mode. The downlink signal may include or correspond to the RS 880.

[0124] At block 1306, the UE transmits an uplink signal in the uplink BWP in at least one of one or more symbols while in full-duplex mode. The uplink signal may include or correspond to the SRS 876.

[0125] In some implementations, the UE receives mode configuration information from a primary cell or a primary-secondary cell. The mode configuration information may be received in a control message (such as control message 872). The mode configuration information may include or correspond to mode information 815. Based on the mode configuration information, the UE is configured to be in full-duplex mode, such as in-band full-duplex mode or sub-band full-duplex mode. The UE determines its self-interference, such as the amount of interference caused by the uplink signal transmitted by the UE to the downlink signal received by the UE.

[0126] In some implementations, the UE is configured for the dormant downlink BWP based on the secondary cell being in a dormant state. The dormant state may include or correspond to the dormant BWP 722. When the secondary cell is in in-band full-duplex mode or sub-band full-duplex mode, the downlink signal may be received from the secondary cell. The sub-band full-duplex mode may be associated with a configuration including one or more downlink resources and one or more uplink resources, where the one or more downlink resources may be within a first bandwidth of the frequency band and the one or more uplink resources may be within a second bandwidth of the frequency band, and the second bandwidth is separated from the first bandwidth in the frequency domain. In some implementations, the first bandwidth and the second bandwidth are separated by a guard region. The in-band full-duplex mode may be associated with a configuration including one or more downlink resources and one or more uplink resources, where the one or more downlink resources are within a first bandwidth of the frequency band and the one or more uplink resources are within a second bandwidth of the frequency band, and the second bandwidth at least partially overlaps with the first bandwidth in the frequency domain.

[0127] In some implementations, the UE receives one or more configurations in an RRC message from a primary cell or a primary-secondary cell pair. The primary cell or secondary cell may be associated with base station 105. The RRC message may include or correspond to configuration message 870. The RRC message may indicate at least one of the one or more configurations. In some implementations, the one or more configurations define a plurality of resource bandwidths (RBWs) of a dormant downlink BWP. The plurality of RBWs may include or correspond to dormant RBW 808, operation constraints 812, or a combination thereof. The plurality of RBWs may include a first RBW as a first dormant RBW and a second RBW as a second dormant RBW or a non-dormant RBW.

[0128] In some implementations, after receiving the one or more configurations, the UE may receive one or more control messages including DCI from the primary cell or the primary-secondary cell pair. The one or more control messages may include or correspond to control message 872. The UE may configure the UE for the dormant downlink BWP and the uplink BWP based on the one or more control messages.

[0129] In some implementations, after receiving a downlink signal and transmitting an uplink signal, the UE may receive a handover message including DCI. The handover message may include or correspond to handover message 874. The UE may identify a non-dormant downlink BWP based on the handover message. In some implementations, the UE may switch the UE from using the dormant downlink BWP to using the non-dormant downlink BWP based on the handover message. Additionally or alternatively, the UE may monitor a physical downlink control channel or a physical downlink shared channel from a secondary cell in the non-dormant downlink BWP when in full-duplex mode. In some implementations, after switching the UE to the non-dormant downlink BWP, the UE may transmit a physical uplink control channel or a physical uplink shared channel to the secondary cell in the uplink BWP when the secondary cell is in an active, non-dormant state when in full-duplex mode. For example, the physical uplink control channel may include or correspond to PUCCH 878. The active, non-dormant state may include or correspond to non-dormant BWP 724.

[0130] Figure 14 is a flow chart illustrating an example process 1400 for downlink communication supporting a dormant BWP configuration that can be used for full-duplex operation. The operations of process 1400 may be performed by a UE, such as UE 115 described above with reference to Figure 1 、 2 、3A, 3B, 3C, and 8, or with reference to Figure 16The described UE 1600. For example, the example operations (also referred to as "blocks") of process 1400 may enable UE 400 to support a dormant BWP.

[0131] In block 1402, the UE receives one or more configurations for the dormant BWP. The dormant BWP may include or correspond to the first BWP 806. The dormant downlink BWP is associated with a secondary cell for which the UE does not need to monitor the physical downlink control channel. The secondary cell may be associated with the base station 860. In some implementations, the UE receives the one or more configurations in an RRC message from the primary cell or the primary-secondary cell. The RRC message may indicate the one or more configurations.

[0132] In block 1404, the UE receives an indication of a first RBW among a plurality of RBWs that can be configured in the dormant downlink BWP. Each RBW may span at least a portion of the dormant downlink BWP in the frequency domain. In some implementations, this portion of the dormant downlink BWP in the frequency domain is non-contiguous. Each RBW may be associated with a set of one or more operation constraints. The set of one or more operation constraints may include or correspond to the operation constraints 812. The plurality of RBWs may include one or more dormant RBWs in which the UE does not need to monitor the physical downlink control channel (such as PDCCH 882).

[0133] In block 1406, the UE monitors the downlink signal in the first RBW. The downlink signal may include or correspond to the RS 880.

[0134] In some implementations, the UE receives a configuration for the uplink BWP. The configuration may be received in a configuration message (such as configuration message 870). Additionally or alternatively, the UE receives mode configuration information from the primary cell or the primary-secondary cell. The mode configuration information may include or correspond to the mode information 815. The UE may configure the UE to be in a full-duplex mode, such as an in-band full-duplex mode or a sub-band full-duplex mode. The UE may be in the full-duplex mode during monitoring of the downlink signal in the first RBW.

[0135] In some implementations, each of the RBWs among the plurality of RBWs is associated with a set of one or more operation constraints. The one or more operation constraints are associated with at least one of the following: monitoring one or more downlink reference signals, monitoring the physical downlink control channel, monitoring the physical downlink shared channel, measuring self-interference, measuring cluster reflections, or performing measurements associated with full-duplex operation. The downlink reference signal may include CSI-RS.

[0136] In some implementations, the plurality of RBWs includes one or more non-dormant RBWs, in each of which the UE is configured to monitor the physical downlink control channel. Based on the identified RBW being a dormant RBW, the UE monitors the CSI-RS. Additionally, based on the first RBW being a non-dormant RBW, the UE may monitor the physical downlink shared channel.

[0137] In some implementations, after monitoring the downlink signal in the first RBW, the UE may receive a handover message including DCI from the primary cell or the secondary primary cell. The primary cell or the secondary primary cell may be associated with the base station 105. The handover message may include or correspond to the handover message 874. The UE may identify a second RBW among the plurality of RBWs based on the handover message. Additionally or alternatively, the UE may switch the UE from operating according to a first set of one or more operating constraints associated with the first RBW to operating according to a second set of one or more operating constraints associated with the second RBW.

[0138] In some implementations, after monitoring the downlink signal in the first RBW, the UE may identify that a period of time has elapsed. Based on the determination that the period of time has elapsed, the UE may identify a second RBW among the plurality of RBWs based on the RRC configuration criteria. The RRC configuration criteria may be associated with an RBW ID value, a previous active RBW, or a default RBW. The UE may switch from operating according to a first set of one or more operating constraints associated with the first RBW to operating according to a second set of one or more operating constraints associated with the second RBW based on the RRC configuration criteria. For example, the UE may switch to using the RBW with the lowest ID or the highest ID instead of the current RBW. As another example, the UE may switch to using the most recent active RBW instead of using the current RBW. As another example, the UE may switch to using the default RBW, such as the RBW configured as the default by the RRC. In some implementations, if the default is the current RBW at the time of handover, the UE may alternatively switch to using the RBW with the lowest ID, the RBW with the highest ID, or the most recent active RBW.

[0139] In some implementations, the first RBW among the plurality of RBWs is a first dormant RBW, and the second RBW is a second dormant RBW. The first dormant RBW may be associated with a first portion of the bandwidth of the dormant downlink BWP, and the second dormant RBW may be associated with a second portion of the bandwidth of the dormant downlink BWP that is different from the first portion. Additionally or alternatively, the first set of one or more operating constraints may be different from the second set of one or more operating constraints.

[0140] In some implementations, based on the first RBW being a non-dormant RBW, when the UE is in full-duplex mode, it monitors the physical downlink control channel or the physical downlink shared channel from the secondary cell in the non-dormant downlink RBW. Additionally or alternatively, the UE may switch from operating according to a first set of one or more operating constraints associated with the first RBW to operating according to a second set of one or more operating constraints associated with the second RBW. The second RBW may be a dormant RBW. In some implementations, the first RBW is a default non-dormant RBW, the second RBW is a default dormant RBW, or a combination thereof.

[0141] In some implementations, after monitoring the downlink signal in the first RBW, the UE receives a handover message including DCI from the primary cell or the secondary primary cell. The handover message may include or correspond to handover message 874. The UE may identify another downlink BWP based on the handover message. The other BWP may be another dormant downlink BWP or a non-dormant downlink BWP. The UE may switch from monitoring at least a portion of the first bandwidth of the dormant downlink BWP to monitoring at least a portion of the second bandwidth of the other BWP.

[0142] Figure 15 is a flow chart illustrating an example process 1500 that supports a dormant BWP configuration that can be used for full-duplex operation for one of downlink or uplink communication according to some aspects. The operations of process 1500 may be performed by a UE, such as UE 115 described above with reference to Figure 1 , 2 , 3A, 3B, 3C, and 8, or UE 1600 described with reference to Figure 16 . For example, the example operations (also referred to as "blocks") of process 1500 may enable UE 400 to support a dormant BWP.

[0143] In block 1502, the UE receives one or more configurations for a dormant downlink BWP. The one or more configurations may include or correspond to BWP information 805. The dormant downlink BWP is associated with a secondary cell for which the UE does not need to monitor the physical downlink control channel. The secondary cell may be associated with base station 860.

[0144] In block 1504, the UE receives a first indication of a first resource bandwidth (RBW) among a plurality of RBWs that can be configured in a dormant downlink BWP. Each of the plurality of RBWs spans at least a portion of the dormant downlink BWP in the frequency domain. Additionally, each of the plurality of RBWs is associated with a set of one or more operation constraints. The plurality of RBWs includes one or more dormant RBWs in which the UE does not need to monitor the physical downlink control channel and includes at least one uplink dormant RBW. The first RBW includes either a downlink dormant RBW or an uplink dormant RBW among the plurality of RBWs.

[0145] In block 1506, the UE performs one or more operations for the first RBW based on receiving the first indication and based on a first set of one or more operation constraints associated with the first RBW. The first set of one or more operation constraints may include or correspond to operation constraint 812.

[0146] In some implementations, the UE receives a second indication of a second RBW among the plurality of RBWs from a primary cell or a secondary primary cell. The primary cell or the secondary primary cell may be associated with the base station 105. The second RBW includes the other of the downlink dormant RBW and the uplink dormant RBW. The second RBW may be associated with a second set of one or more operation constraints.

[0147] In some implementations, the UE uses a second set of one or more operation constraints associated with the second RBW based on the second indication. The first set of one or more operation constraints may be different from the second set of one or more operation constraints.

[0148] In some implementations, the UE determines that the downlink dormant RBW is a default downlink dormant RBW based on one or more configurations. Additionally or alternatively, the UE determines that the uplink dormant RBW is a default uplink dormant RBW based on one or more configurations.

[0149] In some implementations, the UE may select a downlink dormant RBW for the UE based on the first indication. Additionally, performing one or more operations for the first RBW based on the first set of one or more operation constraints includes performing one or more operations when operating in full duplex mode and operating in the downlink dormant RBW. By way of illustration, the one or more operations may include receiving a downlink signal in the downlink dormant RBW, measuring a downlink reference signal for RRM, RLM, or a combination thereof.

[0150] In some implementations, a UE may select an uplink dormant RBW for the UE based on a first indication. Additionally, performing one or more operations for a first RBW based on a first set of one or more operational constraints includes performing the one or more operations while operating in a full-duplex mode. By way of illustration, the one or more operations may include transmitting an uplink signal in the uplink dormant RBW. Additionally, while operating based on the first set of one or more operational constraints and in a full-duplex mode, the UE may determine self-interference at the UE. The self-interference may be associated with the amount of interference caused by an uplink signal transmitted by the UE to a downlink signal received by the UE. For example, one of the uplink signals is transmitted in a first RBW of a plurality of RBWs or one of the downlink signals is received in a first RBW of a plurality of RBWs. In some implementations, a dormant downlink RBW is associated with a first portion of the bandwidth of a dormant downlink BWP, and a dormant uplink RBW is associated with a second portion of the bandwidth that is different from the first portion of the bandwidth. Additionally or alternatively, the first set of one or more operational constraints for the dormant downlink RBW may be different from the second set of one or more operational constraints for the dormant uplink RBW.

[0151] As referred to Figures 13 - 15 as described, the present disclosure provides techniques for using a dormant BWP. In some implementations, a dormant BWP may include a plurality of RBWs having at least one dormant RBW associated with a first set of one or more operational constraints that the UE 115 may perform. Different operational constraints for different RBWs may provide flexibility and customization for the system and the device. Additionally, switching configured to be performed between different RBWs using a BWP may be performed faster than switching between different BWPs. Accordingly, the use of a dormant BWP including a plurality of RBWs may improve the operational efficiency of the UE and reduce service latency and interruption.

[0152] Figure 16 is a block diagram of an example UE 1600 that supports a dormant BWP configuration that may be used for full-duplex operation for downlink communication according to some aspects. The UE 1600 may be configured to perform operations including the blocks of the processes described with reference to Figures 13 - 15 to use a dormant BWP. In some implementations, the UE 1600 includes the reference to Figure 2UE 115 shown and described with respect to FIGS. 8 or 11. For example, UE 1600 includes a controller 280 that operates to execute logic or computer instructions stored in a memory 282 and to control the various components of UE 1600 that provide the features and functionality of UE 1600. UE 1600 transmits and receives signals under the control of controller 280 via wireless radios 1601a-r and antennas 252a-r. The wireless radios 1601a-r include various components and hardware, as described with respect to UE 115 in Figure 2 including modulators and demodulators 254a-r, MIMO detectors 256, receive processors 258, transmit processors 264, and TX MIMO processors 266.

[0153] As shown, memory 282 may include BWP information 1602, channel quality information 1603, mode information 1604, and timer logic 1605. BWP information 1602, channel quality information 1603, and mode information 1604 may include or correspond to BWP information 805, channel quality information 814, and mode information 815. Timer logic 1605 may include or correspond to a timer. UE 1600 may receive signals from or transmit signals to one or more network entities, such as Figure 1 , 2 , base stations 105 of FIGS. 3A, 3B, 3C, and 8, or base stations as described in Figure 18 .

[0154] Figure 17 is a flow diagram depicting an example process 1700 that illustrates a sleep BWP configuration that may be used to support full duplex operation for downlink communication in accordance with some aspects. The operations of process 1700 may be performed by a base station, such as base station 105 described above with reference to Figure 1 -4, 8, or base stations described above with reference to Figure 18 . For example, the example operations of process 1700 may cause base station 105 to support a sleep BWP.

[0155] In block 1702, the base station generates a configuration message that includes BWP information associated with the sleep BWP. The BWP information may include or correspond to BWP information 805. The configuration message may include or correspond to configuration message 870. The sleep BWP is associated with a secondary cell for which the UE does not need to monitor the physical downlink control channel. The secondary cell may be associated with base station 860.

[0156] In block 1704, the base station transmits the configuration message to the UE. For example, the configuration message may include or correspond to configuration message 870.

[0157] In some implementations, after transmitting a configuration message, the base station transmits a first handover message to the UE. The first handover message may include or correspond to handover message 874. The first handover message may be configured to cause the UE to switch from using a dormant BWP to using another BWP (such as a non-dormant BWP). For example, the first handover message may be configured to cause UE 115 to switch from using first BWP 806 to using second BWP 813.

[0158] In some implementations, the dormant BWP includes a plurality of RBWs. The plurality of RBWs may include or correspond to dormant RBW 808, non-dormant 810, or a combination thereof. In some implementations, the plurality of RBWs includes a first dormant RBW that includes a subset of the frequency band that includes the dormant BWP. For example, the dormant BWP may include or correspond to dormant RBW 808. The dormant RBW may be associated with one or more operating constraints (such as operating constraint 812). The one or more operating constraints associated with the first dormant RBW may be different from the one or more operating constraints associated with another dormant RBW in the plurality of RBWs.

[0159] In some implementations, after transmitting a configuration message, the base station transmits a second handover message to the UE. The second handover message may include or correspond to handover message 874. The second handover message may be configured to cause the UE to switch from using a dormant RBW to using another RBW in the plurality of RBWs. The other RBW may include another dormant RBW or a non-dormant RBW.

[0160] In some implementations, the plurality of RBWs further includes a non-dormant RBW. For example, the non-dormant BWP may include or correspond to non-dormant RBW 810. Additionally or alternatively, the dormant RBW may be a default dormant RBW, the non-dormant RBW may be a default non-dormant RBW, the second handover message may include DCI, or a combination thereof.

[0161] In some implementations, the base station may transmit a DCI or an RRC message that indicates the duration of a period associated with the UE switching from using a dormant RBW to using another RBW (such as a non-dormant RBW). The DCI or RRC message may include or correspond to configuration message 870 or control message 872.

[0162] In some implementations, the plurality of RBWs includes a downlink dormant RBW, an uplink dormant RBW, or a combination thereof. For example, the downlink dormant RBW and the uplink dormant RBW may include or correspond to DL dormant RBW 1151 and UL dormant RBW 1152, respectively. In some implementations, the plurality of RBWs may include one or more default RBWs. By way of illustration, the downlink dormant RBW may be a default downlink dormant RBW, the uplink dormant RBW may be a default uplink dormant RBW, or a combination thereof.

[0163] In some implementations, the BWP information is associated with a first BWP and a second BWP. The first BWP and the second BWP may respectively include or correspond to the first BWP 806 and the second BWP 813. The first BWP may include a dormant BWP. In some implementations, the second BWP includes a second dormant RBW. For illustration, the first BWP and the second BWP may include or correspond to the first BWP 1210 including the first dormant RBW 1211 and the second BWP 1220 including the second dormant RBW 1222.

[0164] Figure 18 is a block diagram of an example base station 1800 that supports a dormant BWP configuration that can be used for full-duplex operation for downlink communication according to some aspects. The base station 1800 may be configured to perform operations including the blocks of process 1700 described with reference to Figure 17 to support a dormant BWP. In some implementations, the base station 1800 includes the structures, hardware, and components shown and described for the base station 105 with reference to Figure 1 -4 and 8. For example, the base station 1800 may include a controller 240 that operates to execute logic or computer instructions stored in a memory 242 and to control the various components that provide the features and functionality of the base station 1800. The base station 1800 transmits and receives signals under the control of the controller 240 via radios 1801a-t and antennas 234a-t. The radios 1801a-t include various components and hardware (as illustrated for the base station 105 in Figure 2 ), including modulators / demodulators 232a-t, transmit processors 220, TX MIMO processors 230, MIMO detectors 236, and receive processors 238.

[0165] As shown, the memory 242 may include BWP information 1802 and Scell information 1803. The BWP information 1802 may include or correspond to the BWP information 805. The Scell information 1803 may include or correspond to the ID or status of a base station or Scell (such as the base station 860). The base station 1800 may receive signals from one or more UEs (such as Figure 1 、 2 、UEs 115 of 3A, 3B, 3C, and 8, or Figure 16 UE 1600) or transmit signals to one or more UEs.

[0166] It should be noted that one or more blocks (or operations) described with reference to Figures 13 - 15 and 17 may be combined with one or more blocks (or operations) described with reference to another figure. For example, Figures 13 - 15 one or more blocks (or operations) of Figure 17One or more combinations of boxes (or operations). As another example, one or more boxes associated with Figure 13 can be combined with one or more boxes associated with Figure 14 or 15. As another example, one or more boxes associated with Figures 13 - 15 or 17 can be combined with one or more boxes (or operations) associated with Figure 1 , 2 , 3A, 3B, 3C, or 8. Additionally or alternatively, one or more operations described above with reference to Figure 1 , 2 , 3A, 3B, 3C, or 8 can be combined with one or more operations described with reference to Figure 14 or 16.

[0167] In some aspects, techniques for supporting a dormant BWP configuration that can be used for full-duplex operation for downlink communication may include additional aspects, such as any single aspect or any combination of aspects described below or in combination with one or more other processes or devices described elsewhere herein.
