Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly to wireless communication systems using full-duplex communications.

[0004] Related technical description

[0005] Wireless communication networks are widely deployed to provide various communication services, such as voice, video, packet data, messaging, broadcast, etc. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks, which are typically multiple-access networks, support communication for multiple users by sharing the available network resources.

[0006] A wireless communication network may include several base stations or Node Bs that can support communications for several user equipments (UEs). A UE may communicate with a base station via a downlink and an uplink. A downlink (or forward link) refers to the communication link from a base station to a UE, while an uplink (or reverse link) refers to the communication link from a UE to a base station.

[0007] The base station may transmit data and control information to the UE on the downlink and / or may receive data and control information from the UE on the uplink. On the downlink, the transmission from the base station may encounter interference caused by transmissions from neighboring base stations or from other wireless radio frequency (RF) transmitters. On the uplink, the transmission from the UE may encounter interference from uplink transmissions of other UEs communicating with the neighboring base stations or from other wireless RF transmitters. This interference may degrade the performance of both the downlink and uplink.

[0008] As the demand for mobile broadband access continues to grow, the potential for interference and congested networks continues to grow as more UEs access long-range wireless communication networks and more short-range wireless systems are being deployed in communities. Research and development continues to advance wireless technologies to not only meet the growing demand for mobile broadband access, but also to improve and enhance the user experience with mobile communications.

[0032] Detailed Description

[0033] A wireless communication system according to some aspects of the present disclosure may perform selective grouping of demodulation reference signals (DMRS). Selective grouping may include sharing of DMRS or bundling of DMRS. For illustration, DMRS bundling may include receiving a signal using multiple DMRSs that are "bundled" together, and DMRS sharing may include receiving a signal using a single DMRS that is "shared" between the signals.

[0034] In some aspects, DMRS grouping may be selectively performed based on a full-duplex resource configuration associated with a resource for transmitting a signal. For example, if a full-duplex resource configuration for transmitting a signal satisfies a condition for DMRS grouping, a transmitter device may perform a DMRS grouping operation on the signals (e.g., by bundling or sharing the one or more DMRSs in the full-duplex resource configuration), and the signals are received by a receiver device (e.g., by receiving the signals according to the DMRS grouping operation). If two or more full-duplex resource configurations fail to meet the condition, each full-duplex resource configuration may receive a corresponding DMRS (wherein the DMRS is not shared or bundled).

[0035] These DMRS grouping operations may be performed by a base station, by a user equipment (UE) device, or both. For illustration, in some implementations, a transmitter device corresponds to one of a base station or a UE device, and a receiver device corresponds to the other of a base station or a UE device. DMRS grouping operations may be performed for one or more downlink physical (PHY) channels (e.g., a physical downlink shared channel (PDSCH) or a physical downlink control channel (PDCCH)), one or more uplink PHY channels (e.g., a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH), or a combination thereof.

[0036] Selectively performing DMRS grouping operations can improve the performance of a wireless communication system. For example, in some cases, a device of the wireless communication system can selectively group DMRS, which can increase the quality of a channel estimation operation (e.g., by using multiple DMRS instead of a single DMRS to determine a channel estimate), which can enhance the quality of a signal received based on the channel estimate. As another example, in some cases, the device can selectively share DMRS, which can increase the amount of resources available for conveying other signals (such as data signals) compared to using multiple DMRS.

[0037] In other cases, DMRS grouping can be selectively avoided. For example, if DMRS grouping within a full-duplex resource configuration will result in certain events, such as a reduction in the phase coherence of one or more signals, these full-duplex resource configurations may not meet the conditions for DMRS grouping. For illustration, a change in characteristics from one full-duplex resource configuration to another can be associated with a change in the phase of a local oscillator (LO). In this case, DMRS grouping can be selectively avoided for these full-duplex resource configurations, which can increase or maintain phase coherence in some cases, such as by maintaining the phase of the LO. As a result, the signal quality (or reception quality of the signal) in the wireless communication system can be enhanced.

[0038] For further explanation, certain aspects of the present disclosure relate to 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 / devices), and other communication networks. As described herein, the terms "network" and "system" may be used interchangeably.

[0039] A CDMA network may implement, for example, a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband-CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers IS-2000, IS-95 and IS-856 standards.

[0040] TDMA networks can, for example, implement radio technologies such as GSM. 3GPP defines standards for GSM EDGE (Enhanced Data Rates for GSM Evolution) Radio Access Network (RAN) (also referred to as GERAN). GERAN is the radio component of GSM / EDGE together with the network that interfaces base stations (e.g., Ater and Abis interfaces) with base station controllers (A interfaces, 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 subscriber handsets (also known as user terminals or user equipment (UE)) and from subscriber handsets to the PSTN and the Internet. The network of a mobile phone operator may include one or more GERANs, which may be coupled to a universal terrestrial radio access network (UTRAN) in the case of a UMTS / GSM network. The operator network may also include one or more LTE networks, and / or one or more other networks. Various network types may use different radio access technologies (RATs) and radio access networks (RANs).

[0041] OFDMA network can realize radio technologies such as Evolved UTRA (E-UTRA), IEEE 802.11, IEEE802.16, IEEE802.20, flash-OFDM, etc. UTRA, E-UTRA and Global System for Mobile Communications (GSM) are parts of Universal Mobile Telecommunications System (UMTS). Specifically, Long Term Evolution (LTE) is a version of UMTS using E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents provided by an organization named "3rd Generation Partnership Project" (3GPP), while cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies and standards are known or under development. For example, the 3rd Generation Partnership Project (3GPP) is a collaboration between various telecommunications association groups that aims to define a globally applicable third generation (3G) mobile phone specification. 3GPP Long Term Evolution (LTE) is a 3GPP project aimed at improving the Universal Mobile Telecommunications System (UMTS) mobile phone standard. 3GPP may define specifications for next generation mobile networks, mobile systems, and mobile devices. The present disclosure focuses on the evolution of wireless technologies from LTE, 4G, 5G, NR and beyond with shared access to wireless spectrum between networks using a set of new and different radio access technologies or radio air interfaces.

[0042] 5G networks envision a variety of deployments, various spectrums, and a variety of services and devices that can be implemented using a unified air interface based on OFDM. 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: (1) massive Internet of Things (IoT) with ultra-high density (e.g., about 1M nodes / km^2), ultra-low complexity (e.g., about tens of bits / second), ultra-low energy (e.g., about 10+ years of battery life), and deep coverage capable of reaching challenging locations; (2) mission-critical control including strong security (to protect sensitive personal, financial, or confidential information), ultra-high reliability (e.g., about 99.9999% reliability), ultra-low latency (e.g., about 1ms), and users with a wide range of mobility or lack of mobility; and (3) enhanced mobile broadband including extremely high capacity (e.g., about 10Tbps / km^2), extreme data rates (e.g., multi-Gbps rates, 100+Mbps user experience rates), and deep awareness with advanced discovery and optimization.

[0043] 5G NR devices, networks, and systems can be implemented to use optimized OFDM-based waveform features. These features may include: scalable parameter sets and transmission time intervals (TTIs); a common, flexible framework to efficiently multiplex services and features using dynamic low-latency time time division duplex (TDD) / frequency division duplex (FDD) designs; and advanced wireless 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 in 5G NR (and the scaling of subcarrier spacing) can efficiently solve the problem of operating diverse services across diverse spectrums and diverse deployments. For example, in various outdoor and macro coverage deployments less than 3GHz FDD / TDD implementations, the subcarrier spacing can occur, for example, at 15kHz on bandwidths such as 1, 5, 10, 20MHz. For other various outdoor and small cell coverage deployments of TDD greater than 3GHz, the subcarrier spacing can occur at 30kHz on 80 / 100MHz bandwidths. For various other indoor broadband implementations, subcarrier spacing can occur at 60kHz over a 160MHz bandwidth using TDD on the unlicensed portion of the 5GHz band. Finally, for various deployments transmitting with the mmWave component at 28GHz TDD, subcarrier spacing can occur at 120kHz over a 500MHz bandwidth.

[0044] 5G NR's scalable parameter set facilitates scalable TTI 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. Efficient multiplexing of long TTIs and short TTIs allows transmissions to start on symbol boundaries. 5G NR also contemplates a self-contained integrated subframe design with uplink / downlink scheduling information, data, and acknowledgment in the same subframe. Self-contained integrated subframes support communications in unlicensed or contention-based shared spectrum, supporting adaptive uplink / downlink that can be flexibly configured on a per-cell basis to dynamically switch between uplink and downlink to meet current traffic needs.

[0045] For clarity, certain aspects of various devices and techniques may be described below with reference to exemplary LTE implementations or in an LTE-centric manner, and LTE terminology may be used in parts of the following description as an illustrative example; however, the description is not intended to be limited to LTE applications. Rather, the present disclosure focuses on shared access to wireless spectrum between networks using different radio access technologies or radio air interfaces, such as those of 5G NR.

[0046] Furthermore, it should be understood that in operation, a wireless communication network adapted according to the concepts herein may operate with any combination of licensed or unlicensed spectrum, depending on load and availability. Therefore, it will be apparent to those skilled in the art that the systems, devices, and methods described herein may be applied to other communication systems and applications than the specific examples provided.

[0047] Although various aspects and embodiments are described in this application by explanation of some examples, it will be understood by those skilled in the art that additional implementations and use cases can be generated in many different arrangements and scenarios. The innovation described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, each embodiment and / or use can be generated via an integrated chip embodiment and / or other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / shopping equipment, medical equipment, AI-enabled devices, etc.). Although some examples may or may not be specifically for each use case or application, the wide applicability of the described innovation may occur. The scope of each implementation can range from chip-level or module components to non-module, non-chip-level implementations, and further to the aggregation, distributed or OEM devices or systems that incorporate one or more described aspects. In some practical environments, the equipment incorporating the various aspects and features described may also necessarily include additional components and features for implementing and practicing the claimed and described embodiments. The innovations described herein are intended to be practiced in a wide variety of implementations, including both large and small devices of varying sizes, shapes, and compositions, chip-level components, multi-component systems (e.g., RF chains, communication interfaces, processors), distributed arrangements, end-user devices, and the like.

[0048] Figure 1 A wireless network 100 for communication according to some embodiments is shown. The wireless network 100 may, for example, include a 5G wireless network. As appreciated by those skilled in the art, Figure 1 The components appearing in are likely to have related counterparts in other network arrangements, including, for example, cellular network arrangements and non-cellular network arrangements (eg, device-to-device or peer-to-peer or ad hoc network arrangements, etc.).

[0049] Figure 1The wireless network 100 illustrated in the figure includes several base stations 105 and other network entities. The base station can be a station that communicates with the UE, and can also be referred to as an evolved B node (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 and / or a 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 station 105 can be associated with the same operator or different operators (for example, the wireless network 100 can include multiple operator wireless networks), and can use one or more frequencies (for example, one or more frequency bands in a licensed spectrum, an unlicensed spectrum, or a combination thereof) in the same frequency as the adjacent cell to provide wireless communication. In some examples, an individual base station 105 or UE 115 can be operated by more than one network operating entity. In other examples, each base station 105 and UE 115 can be operated by a single network operating entity.

[0050] A base station may provide communication coverage for a macro cell or a small cell (such as a pico cell or a femto cell), and / or other types of cells. A macro cell generally covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs that have a service subscription with a network provider. A small cell (such as a pico cell) generally covers a relatively small geographic area and may allow unrestricted access by UEs that have a service subscription with a network provider. A small cell (such as a femto cell) generally also covers a relatively small geographic area (e.g., a residence) and, in addition to unrestricted access, may also provide restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in the residence, etc.). A base station for a macro cell may be referred to as a macro base station. A base station for a small cell may be referred to as a small cell base station, a pico base station, a femto base station, or a home base station. In Figure 1 In the example shown in FIG. 1 , 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 increase coverage and capacity using 3D beamforming in both elevation and azimuth beamforming. Base station 105f is a small cell base station, which may be a home node or a portable access point. The base station may support one or more (e.g., two, three, four, etc.) cells.

[0051] The wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, each base station may have similar frame timing, and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, each base station may have 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 or asynchronous operation.

[0052] UE 115 is dispersed throughout the wireless network 100, and each UE can be stationary or mobile. It should be appreciated that although mobile devices are generally referred to as user equipment (UE) in the standards and specifications promulgated by the 3rd Generation Partnership Project (3GPP), such devices may also be referred to as mobile stations (MS), subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals (AT), mobile terminals, wireless terminals, remote terminals, handsets, terminals, user agents, mobile clients, clients, gaming devices, augmented reality devices, vehicle-mounted component devices / modules, or some other suitable terminology by those skilled in the art. Within this document, a "mobile" device or UE does not necessarily have mobile capabilities and can be stationary. Some non-limiting examples of mobile devices such as may include embodiments of one or more of the UEs 115 include a mobile station, a cellular phone (handset), a smart phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a laptop, a personal computer (PC), a notebook, a netbook, a smartbook, a tablet, and a personal digital assistant (PDA). The mobile device may additionally be an "Internet of Things" (IoT) or "Internet of Everything" (IoE) device, such as a car or other transportation vehicle, a satellite radio, a global positioning system (GPS) device, a logistics controller, a drone, a multicopter, a quadcopter, a smart energy or security device, a solar panel or solar array, city lighting, water or other infrastructure; industrial automation and enterprise devices; consumer and wearable devices, such as glasses, wearable cameras, smart watches, health or fitness trackers, mammal implantable devices, gesture tracking devices, medical devices, digital audio players (e.g., 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 including a universal integrated circuit card (UICC). In another aspect, a UE may be a device that does not include a UICC. In some aspects, a UE that does not include a UICC may also be referred to as an IoE device. Figure 1UEs 115a-115d of the illustrated embodiment are examples of mobile smartphone-type devices accessing the wireless network 100. A UE may also be a machine specifically configured for connected communications, including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. Figure 1 The UEs 115e - 115k illustrated in FIG. 1 are examples of various machines configured for communications to access the wireless network 100 .

[0053] A mobile device, such as UE 115, may be able to communicate with any type of base station, whether macro, pico, femto, relay, etc. Figure 1 In the embodiment of the present invention, a lightning beam (e.g., a communication link) indicates a wireless transmission between a UE and a serving base station (a serving base station is a base station designated to serve the UE on a downlink and / or uplink), or an expected transmission between base stations, and a backhaul transmission between base stations. In some scenarios, a UE may operate as a base station or other network node. Backhaul communications between base stations of the wireless network 100 may occur using wired and / or wireless communication links.

[0054] In operation of the wireless network 100, base stations 105a-105c use 3D beamforming and coordinated spatial techniques such as coordinated multipoint (CoMP) or multi-connectivity to serve UEs 115a and 115b. Macro base station 105d performs backhaul communications with base stations 105a-105c and small cell base station 105f. Macro base station 105d also transmits multicast services subscribed to and received by UEs 115c and 115d. Such multicast services may include mobile television 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.

[0055] The wireless network 100 of various embodiments 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 from macro base stations 105d and 105e, and small cell base station 105f. Other machine-type devices, such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device), can communicate directly with base stations, such as small cell base station 105f and macro base station 105e, through the wireless network 100, or communicate through the 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, which is then reported to the network through small cell base station 105f). The wireless network 100 may also provide additional network efficiency through dynamic, low latency TDD / FDD communications, such as in a vehicle-to-vehicle (V2V) mesh network between UEs 115i - 115k communicating with a macro base station 105e.

[0056] Figure 2 A block diagram shows a design of a base station 105 and a UE 115, which may be Figure 1 For a restricted association scenario (as mentioned above), the base station 105 may be Figure 1 105f, and UE 115 may be UE 115c or 115D operating in the service area of ​​​​the base station 105f. In order to access the small cell base station 105f, the UE 115 will be included in the accessible UE list of the small cell base station 105f. The base station 105 may also be some other type of base station. Figure 2 As shown in FIG. 1 , the base station 105 may be equipped with antennas 234a through 234t, and the UE 115 may be equipped with antennas 252a through 252r, for facilitating wireless communication.

[0057] At the base station 105, the transmit processor 220 may receive data from the data source 212 and control information from the controller / processor 240. The control information may be used for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ (automatic repeat request) indicator channel (PHICH), a physical downlink control channel (PDCCH), an enhanced physical downlink control channel (ePDCCH), an MTC physical downlink control channel (MPDCCH), etc. Data may be used for a PDSCH, etc. The transmit processor 220 may process (e.g., encode and symbol map) the data and the control information to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols, such as reference symbols for a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), and a reference signal that is specific to a cell. The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols, where applicable, and may provide an output symbol stream to modulators (MOD) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 232a to 232t may be transmitted via antennas 234a to 234t, respectively.

[0058] At the UE 115, antennas 252a to 252r may receive downlink signals from the base station 105 and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 115 to a data sink 260, and provide decoded control information to a controller / processor 280.

[0059] On the uplink, at the UE 115, the transmit processor 264 may receive and process data from a data source 262 (e.g., data for a physical uplink shared channel (PUSCH)) and control information from the controller / processor 280 (e.g., control information for a physical uplink control channel (PUCCH)). The transmit processor 264 may also generate reference symbols for reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, if applicable, further processed by the modulators 254a through 254r (e.g., 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, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 115. Processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240 .

[0060] The controllers / processors 240 and 280 may direct the operation at the base station 105 and the UE 115, respectively. The controller / processor 240 and / or other processors and modules at the base station 105 and / or the controller / processor 280 and / or other processors and modules at the UE 115 may perform or direct the execution of various processes for the techniques described herein, such as performing or directing Fig. 9 and Fig.10 1 and / or other processes for the techniques described herein. Memories 242 and 282 may store data and program codes for base station 105 and UE 115, respectively. Scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.

[0061] Wireless communication systems operated by different network operating entities (e.g., network operators) may share spectrum. In some instances, one network operating entity may be configured to use the entire designated shared spectrum for at least one period of time, and then another network operating entity may use the entire designated shared spectrum for a different period of time. Thus, in order to allow network operating entities to use the entire designated shared spectrum, and to mitigate interfering communications between different network operating entities, specific resources (e.g., time) may be divided and allocated to different network operating entities for specific types of communications.

[0062] For example, a network operation entity may be allocated certain time resources that are reserved for exclusive communication using the entire shared spectrum by the network operation entity. Other time resources may also be allocated to a network operation entity where the entity has priority over other network operation entities for communication using the shared spectrum. These time resources prioritized for use by the network operation entity may be utilized by other network operation entities on an opportunistic basis if the prioritized network operation entity does not utilize these resources. Additional time resources may be allocated to any network operator to be used on an opportunistic basis.

[0063] Access to the shared spectrum and arbitration of time resources among different network operating entities may be centrally controlled by a single entity, autonomously determined through a predefined arbitration scheme, or dynamically determined based on interactions between wireless nodes of the network operator.

[0064] In some cases, the UE 115 and the base station 105 may operate in a shared radio frequency spectrum band, which may include licensed or unlicensed (e.g., based on contention) spectrum. In the unlicensed frequency portion of the shared radio frequency spectrum band, the UE 115 or the base station 105 may traditionally perform medium sensing procedures to contend for access to the spectrum. For example, the UE 115 or the base station 105 may perform a listen-before-talk (LBT) procedure (such as a clear channel assessment (CCA)) before communicating to determine whether the shared channel is available. CCA may include an energy detection procedure to determine whether there are any other active transmissions. For example, a device may infer that a change in the received signal strength indicator (RSSI) of a power meter indicates that the channel is occupied. Specifically, a signal power concentrated in a specific bandwidth and exceeding a predetermined noise floor may indicate another wireless transmitter. CCA may also include detection of a specific sequence indicating channel use. For example, another device may transmit a specific preamble before transmitting a data sequence. In some cases, the LBT procedure may include the wireless node acting as a proxy for collisions to adjust its own backoff window based on the amount of energy detected on the channel and / or acknowledgment / negative acknowledgment (ACK / NACK) feedback for its own transmitted packets.

[0065] refer to Figure 3 , depicts an illustrative example of a wireless communication system and is generally designated 300. The wireless communication system 300 includes a base station 105 and a UE 115. Although Figure 3 The example illustrates a single base station 105 and a single UE 115, but in other examples, the wireless communication system 300 may include multiple base stations 105, multiple UEs 115, one or more other devices, or a combination thereof.

[0066] During operation, the base station 105 and the UE 115 are configured to communicate using one or more physical (PHY) channels 350. As illustrative examples, the one or more PHY channels 350 may include one or more of a physical downlink shared channel (PDSCH) 352, a physical uplink shared channel (PUSCH) 354, a physical downlink control channel (PDCCH) 356, or a physical uplink control channel (PUCCH) 358.

[0067] In some implementations, one or both of the base station 105 and the UE 115 may receive the control information 302 (e.g., via any of the one or more PHY channels 350, via one or more other channels, or a combination thereof). In one example, the base station 105 is configured to receive the control information 302 from a service provider associated with the wireless communication system 300. The base station 105 (or another base station) may be configured to provide the control information 302 to the UE 115 (e.g., via a configuration message 320). The base station 105 may be configured to store the control information 302 to the memory 242, and the UE 115 may be configured to store the control information 302 to the memory 282.

[0068] The control information 302 indicates one or more conditions 304 and one or more DMRS grouping characteristics 314 associated with the one or more conditions 304. The one or more conditions 304 may include a bundling condition 306. Additionally or alternatively, the one or more conditions 304 may include a sharing condition 308. Figure 3 The example of also illustrates that the one or more DMRS grouping characteristics 314 may include a bundling characteristic 316 associated with the bundling condition 306. Alternatively or additionally, the one or more DMRS grouping characteristics 314 may include a sharing characteristic 318 associated with the sharing condition 308.

[0069] As used herein, DMRS grouping characteristics may refer to bundling of DMRS, sharing of DMRS, or both. DMRS sharing may refer to using a DMRS transmitted during a first time slot to receive (e.g., demodulate) a signal transmitted during a second time slot, wherein the DMRS is not transmitted during the second time slot (or wherein the DMRS transmitted during the second time slot is not used to receive a signal transmitted during the second time slot). DMRS bundling may refer to using both a first DMRS transmitted during a first time slot and a second DMRS transmitted during a second time slot to receive (e.g., demodulate) a signal of the second time slot.

[0070] To further explain, Figure 3It is depicted that the base station 105 and the UE 115 can perform wireless communications 324 based at least in part on the control information 302. The wireless communications 324 are transmitted using the one or more PHY channels 350 scheduled during the plurality of time slots 330. The wireless communications 324 include one or more DMRS, such as DMRS 340.

[0071] As used herein, a "time slot" (e.g., any of the plurality of time slots 336) may refer to any set of consecutive orthogonal frequency division multiplexing (OFDM) symbols that are full-duplex symbols and have any duration, one or more mini-slots, one or more frames, one or more subframes, or any combination thereof. In addition, a "full-duplex time slot" may refer to a time duration during which a downlink (e.g., PDSCH 352, PDCCH 356, another downlink channel, or a combination thereof) is used for communication between devices, and an uplink (e.g., PUSCH 354, PUCCH 358, another uplink channel, or a combination thereof) is used for communication between devices.

[0072] Each time slot in the plurality of time slots 330 may be associated with a resource configuration. One example of a resource configuration is a half-duplex resource configuration, where an uplink transmission or a downlink transmission occurs during a time slot of the wireless communication 324. Another example of a resource configuration for a time slot is a full-duplex configuration. In a full-duplex configuration, uplink transmissions and downlink transmissions may occur simultaneously during a time slot. Figure 3 In the example of , the plurality of time slots 330 includes a first time slot 332 having a first full-duplex resource configuration 334 and further includes a second time slot 336 having a second full-duplex resource configuration 338 .

[0073] In some examples, the bundling characteristic 316 indicates that DMRS bundling is enabled during time slots with full-duplex resource configurations that satisfy the bundling condition 306. In some other examples, the bundling characteristic 316 indicates that DMRS bundling is disabled during time slots with full-duplex resource configurations that satisfy the bundling condition 306. Additionally, in some examples, the sharing characteristic 318 indicates that DMRS sharing is enabled during time slots with full-duplex resource configurations that satisfy the sharing condition 308. In some other examples, the sharing characteristic 318 indicates that DMRS sharing is disabled during time slots with full-duplex resource configurations that satisfy the sharing condition 308.

[0074] To further explain, Figure 4 An illustrative example of wireless communication 324 is depicted. Figure 4 In , wireless communication 324 is transmitted during multiple time slots. Figure 4 In some implementations, wireless communication 324 is transmitted during time slots 402, 404, 406, and 408. Figure 3 The plurality of time slots 330 include time slots 402 , 404 , 406 , and 408 .

[0075] Each time slot 402, 404, 406, and 408 is associated with a corresponding resource configuration, such as the type or number of channels (e.g., the one or more PHY channels 350) scheduled for use during the time slot, and the type of transmission (e.g., uplink or downlink) performed using the channel. For illustration, time slot 402 may be associated with half-duplex resource configuration 482. Time slots 404, 406, and 408 may be associated with full-duplex resource configurations 484, 486, and 488, respectively.

[0076] In some examples, resource configuration can be Figure 3 The time slots 402 may be dynamically changed during operation of the wireless communication system 300. For example, in response to resource availability in the wireless communication system 300, a time slot (such as time slot 402) may be “converted” from a full-duplex configuration to a half-duplex configuration.

[0077] exist Figure 4 In the example of , each time slot 402, 404, 406, and 408 can be associated with a downlink portion, such as a representative downlink portion 410 of time slot 404. In some examples, downlink portion 410 includes data of a physical downlink shared channel (PDSCH). In addition, time slots 404, 406, and 408 can each include an uplink portion, such as a representative uplink portion 416 of time slot 404. In some examples, uplink portion 416 includes data of a physical uplink shared channel (PUSCH). Figure 4 In the examples of FIG. 4 , time slots 404, 406, and 408 include additional downlink portions, such as a representative downlink portion 418 of time slot 404. In some examples, downlink portion 418 includes data for a PDSCH.

[0078] In some implementations, a guard band may be used to separate the uplink and downlink portions of wireless communication 324. For example, Figure 4 The illustrated guard band may separate the uplink and downlink portions of time slots 404 , 406 , and 408 .

[0079] In some examples, wireless communication 324 includes control information. For example, a downlink portion of wireless communication 324 may include downlink control information, such as representative downlink control information 412 for time slot 404. In some implementations, an uplink portion of wireless communication 324 may include uplink control information, such as representative uplink control information 422 for time slot 404.

[0080] exist Figure 4In the example of FIG. 4 , each resource configuration 482, 484, 486, and 484 can be associated with an available bandwidth 450. Available bandwidth 450 can correspond to the amount of bandwidth scheduled for communication during a time slot. In some cases, the actual amount of bandwidth used for communication during a time slot may be different from (e.g., may be less than) the available bandwidth 450. The actual amount of bandwidth used may be referred to as resource bandwidth in this article. For example, the actual bandwidth 452 (e.g., resource bandwidth) used for the downlink portion (e.g., downlink portion 410) of wireless communication 324 may be less than the available bandwidth 450.

[0081] exist Figure 4 In the example of , the downlink portions of resource configurations 482, 484, 486, and 484 may have a common actual bandwidth (actual bandwidth 452). Figure 4 , actual bandwidth 454 of the downlink portion of resource configuration 488 is less than actual bandwidth 452 of the downlink portion of resource configurations 482, 484, and 486 (eg, due to resource availability or other criteria).

[0082] One or more of the resource configurations 482, 484, 486, and 484 may include DMRS. For example, the downlink portion 410 may include a DMRS 414, such as Figure 3 DMRS 340. In some examples, based on Figure 3 According to the control information 302, each time slot of the wireless communication 324 includes or excludes the DMRS.

[0083] According to some aspects of the present disclosure, Figure 3 The one or more conditions 304 of the first full-duplex resource configuration specify that the first bandwidth of the first portion corresponds to the second bandwidth of the second portion of the second time slot. For example, the bundling condition 306 can specify that bundling is enabled (or allowed) for two or more time slots of the wireless communication 324 having a common actual bandwidth. Alternatively or additionally, the sharing condition 308 can specify that sharing is enabled (or allowed) for two or more time slots of the wireless communication 324 having a common actual bandwidth.

[0084] To further illustrate, in some examples, resource configurations 484, 486 satisfy the bundling condition 306 and the sharing condition 308 by having a downlink portion that includes a common actual bandwidth 452. Thus, in some examples, resource configurations 484, 486 may share a common DMRS or may include a bundled DMRS. Figure 4 In the example of FIG. 4 , the downlink portion of time slot 406 does not include a DMRS and may share DMRS 414 with the downlink portion of time slot 404 .

[0085] Furthermore, in some examples, resource configuration 488 fails to meet bundling condition 306 and sharing condition 308 because actual bandwidth 454 is different from shared actual bandwidth 452. In this case, time slot 408 may include DMRS that is not shared or bundled with time slots 404, 406.

[0086] In some implementations, half-duplex resource configurations may be excluded from sharing, bundling, or both with time slots. For example, in some implementations, half-duplex resource configuration 482 is excluded from bundling, sharing, or both. In this case, the downlink portion of resource configuration 482 may include DMRS that is not shared or bundled with the downlink portions of resource configurations 484, 486, and 488.

[0087] Figure 5 Another example of wireless communication 324 is depicted. Figure 5 In the embodiment, wireless communication 324 is transmitted during time slots 502, 504, 506, and 508. Time slots 502, 504, 506, and 508 are associated with full-duplex resource configurations 582, 584, 586, and 588, respectively. In some implementations, Figure 3 The plurality of time slots 330 include time slots 502 , 504 , 506 , and 508 .

[0088] In some examples, Figure 5 One or more features of wireless communication 324 as described in reference Figure 4 For example, each of the time slots 502, 504, 506, and 508 may be used to communicate one or more downlink portions (e.g., downlink portions 410, 418), one or more uplink portions (e.g., uplink portion 416), downlink control information (e.g., downlink control information 412), and uplink control information (e.g., uplink control information 422).

[0089] To further illustrate, time slot 508 may be used to communicate uplink portions 510 and 518 and downlink portion 516. Figure 5 In the embodiment, the downlink portion 516 includes a DMRS 522 .

[0090] exist Figure 5 , the downlink portions of resource configurations 582, 584, 586, and 588 are associated with frequency boundary 550 (e.g., a high frequency boundary of the downlink portion) and frequency boundary 552 (e.g., a low frequency boundary of the downlink portion). Downlink portion 516 is associated with frequency boundary 552 (e.g., a high frequency boundary of downlink portion 516) and frequency boundary 556 (e.g., a low frequency boundary of downlink portion 516).

[0091] According to some aspects of the present disclosure, Figure 3 The one or more conditions 304 of the wireless communication 324 may specify that a first frequency boundary of the uplink and downlink portions of the first full-duplex resource configuration corresponds to a second frequency boundary of the uplink and downlink portions of the second full-duplex resource configuration. For example, the bundling condition 306 may specify that bundling is enabled (or allowed) for two or more resource configurations of the wireless communication 324, which have a common frequency boundary for both the uplink portion and the downlink portion. Alternatively or additionally, the sharing condition 308 may specify that sharing is enabled (or allowed) for two or more resource configurations of the wireless communication 324, which have a common frequency boundary for both the uplink portion and the downlink portion.

[0092] To further illustrate, in some examples, resource configurations 582, 584, and 586 satisfy the bundling condition 306 and the sharing condition 308 because the uplink and downlink portions have a common frequency boundary. Figure 5 In the example, the downlink portions of resource configurations 582, 584, and 586 have common frequency boundaries 550, 552 and common frequency boundaries 556, 558. As another example, in Figure 5 In the example, the uplink portions of resource configurations 582, 584, and 586 have common frequency boundaries 552, 556. Thus, in some examples, resource configurations 582, 584, and 586 may share a common DMRS or may include a bundled DMRS. Figure 4 In the example of FIG. 5 , the downlink portions of resource configurations 584 and 586 do not include DMRS and may share DMRS 414 with resource configuration 582 .

[0093] Furthermore, in some examples, resource configuration 588 fails to satisfy bundling condition 306 and sharing condition 308 due to having a different downlink frequency boundary than the downlink frequency boundary of resource configurations 582, 584, and 586, due to having a different uplink frequency boundary than the uplink frequency boundary of resource configurations 582, 584, and 586, or both. Figure 5 In the example, the downlink portion 516 has frequency boundaries 552, 556 that are different from the frequency boundaries 550, 552 and 556, 558 of the downlink portions of resource configurations 582, 584, and 586. As another example, in Figure 5 , uplink portions 510, 518 have frequency boundaries 550, 552 and 556, 558 that are different from the frequency boundaries 552, 556 of the uplink portions of resource configurations 582, 584, and 586. Accordingly, resource configuration 588 may include DMRS 522 that is not shared or bundled with resource configurations 582, 584, and 586.

[0094] Figure 6 Another example of wireless communication 324 is depicted. Figure 6 In the embodiment, wireless communication 324 occurs during time slots 602, 604, 606, and 608. Time slots 602, 604, 606, and 608 are associated with full-duplex resource configurations 682, 684, 686, and 688, respectively. In some implementations, Figure 3 The plurality of time slots 330 include time slots 602 , 604 , 606 , and 608 .

[0095] In some examples, Figure 5 One or more features of wireless communication 324 as described in reference Figure 4 For example, each of the time slots 602, 604, 606, and 608 may be used to communicate one or more downlink portions (e.g., downlink portions 410, 418), one or more uplink portions (e.g., uplink portion 416), downlink control information (e.g., downlink control information 412), and uplink control information (e.g., uplink control information 422).

[0096] To further illustrate, time slot 606 may be used to communicate downlink portions 610 and 618 and uplink portion 616. Time slot 608 may be used to communicate downlink portions 620, 628 and uplink portion 626.

[0097] According to some aspects of the present disclosure, Figure 3 The one or more conditions 304 specify that a first frequency boundary of a first uplink or downlink portion of a first full-duplex resource configuration corresponds to a second frequency boundary of a second uplink or downlink portion of a second full-duplex resource configuration. In this example, sharing or bundling may be enabled for uplink portions of wireless communications 324 having a common frequency boundary (regardless of whether the corresponding downlink portions of the wireless communications 324 have frequency boundaries that differ from one another). Alternatively or additionally, sharing or bundling may be enabled for downlink portions of wireless communications 324 having a common frequency boundary (regardless of whether the corresponding uplink portions of the wireless communications 324 have frequency boundaries that differ from one another).

[0098] To explain, in Figure 6 , the downlink portions 410, 610, and 620 have common frequency boundaries 650, 654. Figure 6It is also illustrated that the uplink portions 416, 616 have frequency boundaries 651, 652 and that the uplink portion 626 has frequency boundaries 655, 656 that are different from the frequency boundaries 651, 652. Accordingly, in some aspects of the present disclosure, the control information 302 indicates that the downlink portions 410, 610, and 620 are eligible to be shared with each other, bundled with each other, or both, and further indicates that the uplink portions 416, 616 are eligible to be shared with each other, bundled with each other, or both. Figure 6 In the embodiment of the present invention, the DMRS 414 can be shared between the downlink parts 410, 610 and 620.

[0099] The control information 302 may indicate that the uplink portion 626 is not eligible for sharing, bundling, or both with respect to the uplink portions 416, 616 of the time slots 604, 606. In addition, the control information 302 may indicate that the downlink portions 618, 418 are eligible for sharing, bundling, or both with each other, and that the downlink portion 628 is not eligible for sharing, bundling, or both with the downlink portions 418, 618.

[0100] Figure 7 Another example of wireless communication 324 is depicted. Figure 7 In the example of , wireless communication 324 occurs during time slots 702, 704, 706, 708, 710, 712, and 714. Time slots 704, 706, 710, and 712 may include downlink portions 410, 715, 720, and 730, respectively. Time slots 704, 706, 710, and 712 may be associated with full-duplex resource configurations 784, 786, 790, and 792, respectively. In some implementations, Figure 3 The plurality of time slots 330 include time slots 702 , 704 , 706 , 708 , 710 , 712 , and 714 .

[0101] In some aspects of the present disclosure, Figure 3 The one or more conditions 304 specify that the first time slot is adjacent to the second time slot in time. In this example, time slots adjacent in time may be eligible for sharing, bundling, or both, while time slots non-adjacent in time may not be eligible for sharing, bundling, or both.

[0102] To explain, in Figure 7 , time slot 704 is adjacent in time to time slot 706. Accordingly, in some aspects of the present disclosure, downlink portion 410 is eligible to be shared with downlink portion 715, bundled with downlink portion 715, or both. Figure 7In the example of , the DMRS 414 may be shared between the downlink portions 410, 715. Alternatively or additionally, the downlink portion 410 may include the DMRS 714 shared between the downlink portions 410, 715.

[0103] As another example, in Figure 7 , time slot 710 is adjacent in time to time slot 712. Accordingly, in some aspects of the present disclosure, downlink portion 720 is eligible to be shared with downlink portion 730, bundled with downlink portion 730, or both. Figure 7 In the example of , the downlink portion 720 may include a DMRS 724 shared between the downlink portions 720, 730. Alternatively or additionally, the downlink portion 720 may include a DMRS 734 shared between the downlink portions 720, 730.

[0104] To further illustrate, time slots 706, 710 are non-contiguous in time (eg, because time slot 708 occurs between time slots 706, 710). As a result, in some examples, downlink portions 715, 720 are not eligible for sharing, bundling, or both.

[0105] In addition, although certain conditions are described separately herein for convenience, it should be appreciated that two or more conditions described herein may be combined. In one example, the one or more conditions 304 may be combined with Figure 4 One or more conditions, combined with Figure 5 One or more conditions, combined with Figure 6 One or more conditions, or a combination of them, to specify Figure 4 conditions.

[0106] Figure 8 Another example of wireless communication 324 is depicted. Figure 8 In the example of , wireless communication 324 includes time slots 802, 804, 806, and 808. Time slots 802, 804, 806, and 808 are associated with full-duplex resource configurations 892, 894, 896, and 898, respectively. Time slots 804, 806, and 808 can include downlink portions 410, 810, and 820, respectively. In some implementations, Figure 3 The plurality of time slots 330 include time slots 802 , 804 , 806 , and 808 .

[0107] exist Figure 8In the example of FIG. 1 , each downlink portion 410, 810, and 820 can have an actual bandwidth that is different from the other downlink portions 410, 810, and 820. For example, downlink portion 410 can have an actual bandwidth 882. Downlink portion 810 can have an actual bandwidth 882 that is different from (e.g., smaller than) actual bandwidth 884. Downlink portion 820 can have an actual bandwidth that is different from (e.g., larger than) actual bandwidth 882 and actual bandwidth 884.

[0108] According to some aspects of the present disclosure, Figure 3 The one or more conditions 304 specify one or more criteria among time slots associated with resource configurations having different actual bandwidths, such as actual bandwidths 882, 884, and 886. Figure 8 In the first example, Figure 3 The one or more conditions 304 specify that a first bandwidth of a first downlink portion of a first full-duplex resource configuration is greater than or equal to a second bandwidth of a second downlink portion of a second full-duplex resource configuration, and further specify that the second bandwidth is greater than or equal to a third bandwidth of a third downlink portion of a third full-duplex resource configuration. In a first example, a downlink portion may be eligible for sharing or bundling if an actual bandwidth of the downlink portion does not increase from one time slot to a subsequent time slot.

[0109] To illustrate, according to a first example, downlink portion 810 may be eligible for bundling or sharing with downlink portion 410 because actual bandwidth 882 is greater than or equal to actual bandwidth 884. According to a first example, downlink portion 820 may not be eligible for sharing with downlink portions 410, 410 because actual bandwidth 886 is greater than actual bandwidth 884 of time slot 806.

[0110] In accordance with Figure 8 In the second example, Figure 3 The one or more conditions 304 specify that the first downlink portion of the first full-duplex resource configuration is greater than or equal to the second bandwidth of the second downlink portion of the second full-duplex resource configuration, and further specify that the first bandwidth is greater than or equal to the third bandwidth of the third downlink portion of the third full-duplex resource configuration. In a second example, if an initial time slot of the set has an actual bandwidth of the downlink portion that is greater than the actual bandwidth of a subsequent time slot of the set, the downlink portion may be eligible for sharing or bundling.

[0111] To illustrate, according to the second example, downlink portions 410, 810, and 820 may not be eligible for sharing or bundling because the actual bandwidth 882 of downlink portion 410 is not greater than or equal to the actual bandwidth 886 of downlink portion 820. In another implementation of the second example, downlink portion 810 may be eligible for sharing or bundling with downlink portion 410 (because the actual bandwidth 884 is less than the actual bandwidth 884), and downlink portion 820 may not be eligible for sharing or bundling with downlink portions 410, 810 (because the actual bandwidth 886 is greater than the actual bandwidths 882, 884).

[0112] In accordance with Figure 8 In the third example, Figure 3 The one or more conditions 304 specify that a first bandwidth of a first downlink portion of a first full-duplex resource configuration corresponds to a second bandwidth of a second downlink portion of a second full-duplex resource configuration, and specify that the first bandwidth corresponds to a third bandwidth of a third downlink portion of a third full-duplex resource configuration of the wireless communication. In a third example, a downlink portion of a set of time slots may be eligible for sharing or bundling if the time slots have a common actual bandwidth.

[0113] To explain, in Figure 8 In the example of , downlink portions 410, 810, and 820 do not have a common actual bandwidth. As a result, downlink portions 410, 810, and 820 may not be eligible for sharing, bundling, or both. In some other examples, downlink portions 410, 810, and 820 may have a common actual bandwidth and may be eligible for sharing, bundling, or both.

[0114] Although the description has been made with reference to downlink operation Figure 4-Figure 8 Some examples of, but such operations may be performed in conjunction with uplink operations (as an alternative or in addition to downlink operations). For example, the bundling and sharing operations described herein may be performed in conjunction with PDSCH communications, PUSCH communications, PUCCH communications, PDCCH communications, other communications, or a combination thereof.

[0115] To further illustrate, in some aspects of the present disclosure, an example of full-duplex communication is sub-band frequency division duplex (SBFDD) communication, which may also be referred to as a flexible duplex communication technology. SBFDD communication may involve using different frequency resources (e.g., where downlink resources are separated from uplink resources, such as via a guard band) to simultaneously transmit and receive signals. Another example of full-duplex communication is in-band full-duplex (IBFD) communication, which may involve using shared time and frequency resources (e.g., where time resources partially or completely overlap with frequency resources) to simultaneously transmit and receive signals.

[0116] In some implementations, SBFDD communications may be performed using component carrier bandwidth (CC BW). Figure 4-Figure 8 Each illustrated wireless communication 324 may correspond to a SBFDD wireless communication having a frequency range (illustrated as a vertical axis) corresponding to a CC BW. In some implementations, the CC BW has an uplink bandwidth portion (BWP) of 20 MHz and a downlink BWP of 80 MHz. In other implementations, different bandwidth partitions may be used (e.g., as an illustrative example, depending on interference between the base station and other devices).

[0117] Within the active BWP, different resource bandwidths (BWs) may be defined, and different BWs may be dynamically assigned or indicated. In some examples, downlink control information (DCI) is used to indicate resource BWs. Alternatively or additionally, resource BWs may be configured by radio resource control (RRC). Depending on the example, resource BWs may be contiguous or non-intersecting. In some cases, frequency domain resource assignment (FDRA) may be performed per resource bandwidth, and fewer bits may be used compared to BWP. In some cases, uplink and downlink may have different resource BW configurations. In addition, each resource BW may be associated with a corresponding configuration, such as a resource block group (RBG). Uplink and downlink resource BWs may be non-overlapping (such as in conjunction with SBFDD communications) or partially overlapping (such as in conjunction with IBFD communications). In some examples, "zero delay" switching between resource BWs may be achieved.

[0118] In some aspects of the present disclosure, one or more of DMRS sharing or DMRS bundling may be performed in a full-duplex system across transmissions (or repetitions of the same transmission) subject to one or more conditions. These conditions may specify that two or more of PDSCH, PUSCH, PDCCH, and PUCCH (hereinafter referred to as "PxyCH") use DMRS sharing or bundling. In a first example, these conditions may further specify that PxyCH will be transmitted on a full-duplex (FD) time slot of the same resource BW with the same active BWP. In a variant of the first example, in the case of multiple resource BWs, these conditions may further specify that the downlink and uplink frequency domain portions of the resource BW will be the same. In a second example, these conditions may further specify that PxyCH will be transmitted on a time slot with the same downlink (or uplink) frequency domain boundary (while allowing changes in the uplink (or downlink) frequency domain boundaries between PxyCHs). In a third option, the conditions further specify that the PxyCHs meet the conditions of the first example, the second example, or both, and further specify that the PxyCHs are adjacent to each other (e.g., there are no time slots between the PxyCHs that may have different downlink boundaries, uplink boundaries, or both). In some implementations, the first example corresponds to Figure 4 , a variant of the first example corresponds to Figure 5 The second example corresponds to Figure 6 and the third example corresponds to Figure 7 .

[0119] In some examples, these conditions enable the UE to maintain phase coherence across PxyCH. In addition, the UE 115 may operate based on any of the foregoing examples or may select to operate based on any of the foregoing examples, which may be referred to as the capability of the UE 115. The UE 115 may report the capability (e.g., to the base station 105) by downlink channel, uplink channel, or both. The UE 115 may report the capability (e.g., to the base station 105) by each physical (PHY) channel, such as if the UE 115 has one capability per PDSCH and another capability per PUSCH. As a non-limiting example, the UE 115 may operate according to an example about the PDSCH and may operate according to another example about the PUSCH. The UE 115 may report the capability (e.g., to the base station 105) by frequency band, frequency range, or both.

[0120] In some implementations, the base station 105 may configure one or more of these capabilities to the UE 115. For example, the base station 105 may transmit an indication of one or more of these capabilities to the UE 115 in a DMRS sharing or bundling configuration message.

[0121] In some examples, base station 105 and UE 115 operate based on a wireless communication protocol that specifies one or more characteristics (e.g., "constraints") associated with these capabilities. For example, if the conditions of the first example, the second example, or the third example are met, the wireless communication protocol may specify that UE 115 is expected to bundle PxyCH. Alternatively or additionally, if the conditions of the first example, the second example, or the third example are met, the wireless communication protocol may specify that UE 115 may (or may not) optionally bundle PxyCH.

[0122] refer to Fig. 9 , an illustrative example of a method is depicted and generally designated 900. In some examples, the operations of method 900 are performed by a UE device (such as UE 115).

[0123] The method 900 includes receiving, by a UE device, control information at 902, the control information indicating a condition associated with a DMRS grouping characteristic of a DMRS to be wirelessly communicated using one or more PHY channels. For example, the UE 115 may receive control information 302 indicating the one or more conditions 304 and the one or more DMRS grouping characteristics 314. In some examples, the one or more PHY channels 350 include one or more of a PDSCH 352, a PUSCH 354, a PDCCH 356, or a PUCCH 358. In some examples, the DMRS corresponds to any one of DMRS 340, 414, 522, 714, 724, or 734.

[0124] The method 900 further includes: in response to detecting by the UE device that a first full-duplex resource configuration associated with a first time slot in a plurality of time slots of wireless communication and a second full-duplex resource configuration associated with a second time slot in the plurality of time slots satisfy the condition, performing wireless communication based on the DMRS grouping characteristic indicated by the control information at 904. In some examples, the first time slot corresponds to one of time slots 332, 336, 404-408, 502-508, 604-608, 704-714, and 804-808, and the second time slot corresponds to another of time slots 332, 336, 404-408, 502-508, 604-608, 704-714, and 804-808. In some examples, the first full-duplex resource configuration corresponds to one of the full-duplex resource configurations 334, 338, 484-488, 582-588, 684-688, 784-792, and 892-898, and the second full-duplex resource configuration corresponds to another of the full-duplex resource configurations 334, 338, 484-488, 582-588, 684-688, 784-792, and 892-898.

[0125] In some examples, the wireless communication corresponds to the wireless communication 324. To further illustrate, in some examples, performing the wireless communication includes sending the DMRS to the base station based on the DMRS grouping characteristic. For example, the UE 115 may send any one of the DMRS 414, 522, 714, 724, or 734 to the base station 105 based on the one or more DMRS grouping characteristics 314. In another example, performing the wireless communication includes receiving the DMRS from the base station based on the DMRS grouping characteristic. For example, the UE 115 may receive any one of the DMRS 414, 522, 714, 724, or 734 from the base station 105 based on the one or more DMRS grouping characteristics 314.

[0126] refer to Fig.10 , an illustrative example of a method is depicted and generally designated 1000. In some examples, the operations of method 1000 are performed by a base station device (such as base station 105).

[0127] The method 1000 includes receiving, by a base station, control information indicating conditions associated with a DMRS grouping characteristic of a DMRS to be wirelessly communicated using one or more PHY channels, at 1002. For example, the base station 105 may receive control information 302 indicating the one or more conditions 304 and the one or more DMRS grouping characteristics 314. In some examples, the one or more PHY channels 350 include one or more of a PDSCH 352, a PUSCH 354, a PDCCH 356, or a PUCCH 358. In some examples, the DMRS corresponds to any one of DMRS 340, 414, 522, 714, 724, or 734.

[0128] The method 1000 further includes: in response to detecting by the base station that a first full-duplex resource configuration associated with a first time slot in a plurality of time slots of wireless communication and a second full-duplex resource configuration associated with a second time slot in the plurality of time slots satisfy the condition, performing wireless communication based on the DMRS grouping characteristic indicated by the control information at 1004. In some examples, the first time slot corresponds to one of time slots 332, 336, 404-408, 502-508, 604-608, 704-714, and 804-808, and the second time slot corresponds to another of time slots 332, 336, 404-408, 502-508, 604-608, 704-714, and 804-808. In some examples, the first full-duplex resource configuration corresponds to one of the full-duplex resource configurations 334, 338, 484-488, 582-588, 684-688, 784-792, and 892-898, and the second full-duplex resource configuration corresponds to another of the full-duplex resource configurations 334, 338, 484-488, 582-588, 684-688, 784-792, and 892-898.

[0129] In some examples, the wireless communication corresponds to the wireless communication 324. To further illustrate, in some examples, performing the wireless communication includes sending the DMRS to the UE device based on the DMRS grouping characteristic. For example, the base station 105 can send any one of the DMRS 414, 522, 714, 724, or 734 to the UE 115 based on the one or more DMRS grouping characteristics 314. In another example, performing the wireless communication includes receiving the DMRS from the UE device based on the DMRS grouping characteristic. For example, the base station 105 can receive any one of the DMRS 340, 414, 522, 714, 724, or 734 from the UE 115 based on the one or more DMRS grouping characteristics 314.

As another example, the memory 242 can store DMRS grouping selection instructions 1104 that can be executed by the controller / processor 240 to select a DMRS grouping characteristic 314 based on the one or more conditions 304. As an additional example, the memory 242 can store DMRS generation instructions 1106 that can be executed by the controller / processor 240 to cause the wireless radio 1101a-r to generate the wireless communication 324 according to the selected DMRS grouping characteristic 314.
