Technical field

[0004] Aspects of the present disclosure generally relate to wireless communication systems, and more particularly to wireless communication systems using full - duplex communication. Background art

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

[0006] A wireless communication network may include several base stations or Node Bs capable of supporting the communication of several user equipments (UEs). The UEs can communicate with the base stations via the downlink and the uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station.

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

[0008] Due to the continuous growth of the demand for mobile broadband access, as more UEs access long-range wireless communication networks and more short-range wireless systems are being deployed in communities, the likelihood of interfering with and congesting the network is increasing. Research and development continue to advance wireless technologies to not only meet the growing demand for mobile broadband access but also enhance and improve the user experience of mobile communication.

[0030] According to some aspects of the present disclosure, a wireless communication system can perform selective bundling on demodulation reference signals (DMRS). Selective bundling can include sharing of DMRS or bundling of DMRS. For illustration, DMRS bundling can include receiving a signal using multiple DMRS that are "bundled" together, and DMRS sharing can include receiving a signal using a single DMRS that is "shared" among these signals.

[0031] In some aspects, DMRS bundling can be selectively performed based on a full-duplex resource configuration associated with resources used for transmitting signals. For example, if the full-duplex resource configuration for transmitting signals meets the conditions for DMRS bundling, the transmitter device can perform DMRS bundling operations on these signals (e.g., by clustering or sharing the one or more DMRSs among the full-duplex resource configurations), and the receiver device can receive them (e.g., by receiving the signals according to the DMRS bundling operations). If two or more full-duplex resource configurations do not meet the condition, each full-duplex resource configuration can receive the corresponding DMRS (where the DMRSs are not shared or clustered).

[0032] These DMRS bundling operations can be performed by a base station, by a user equipment (UE) device, or both. For illustration, in some implementations, the transmitter device corresponds to one of the base station or the UE device, and the receiver device corresponds to the other of the base station or the UE device. The DMRS bundling operations can be performed for one or more downlink physical (PHY) channels (e.g., physical downlink shared channel (PDSCH) or physical downlink control channel (PDCCH)), one or more uplink PHY channels (e.g., physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH)), or a combination thereof.

[0033] Selectively performing DMRS bundling operations can improve the performance of a wireless communication system. For example, in some cases, the devices in the wireless communication system can selectively cluster the DMRSs, which can increase the quality of channel estimation operations (e.g., by using multiple DMRSs instead of a single DMRS to determine the channel estimation), which can enhance the quality of the signals received based on the channel estimation. As another example, in some cases, the devices can selectively share the DMRSs, which can increase the amount of resources available for conveying other signals (such as data signals) compared to using multiple DMRSs.

[0034] In other cases, DMRS bundling can be selectively avoided. For example, if DMRS bundling within a full-duplex resource configuration would result in certain events, such as a reduction in the phase coherence of one or more signals, then these full-duplex resource configurations may not meet the conditions for DMRS bundling. 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 scenario, DMRS bundling 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 the reception quality of the signals) in the wireless communication system can be enhanced.

[0035] For further illustration, 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, Long-Term Evolution (LTE) networks, Global System for Mobile Communications (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.

[0036] CDMA networks can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc., for example. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers the IS-2000, IS-95, and IS-856 standards.

[0037] TDMA networks can implement radio technologies such as GSM, for example. The 3GPP defines 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 / EDGE together with the network that joins the base stations (e.g., Ater and Abis interfaces) to the base station controller (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 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 different network types may use different Radio Access Technologies (RATs) and Radio Access Networks (RANs).

[0038] 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 Global System for Mobile Communications (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 literature provided by an organization named "3rd Generation Partnership Project" (3GPP), while cdma2000 is described in literature 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 cooperation among groups of telecommunications associations that aims to define globally applicable 3rd generation (3G) mobile phone specifications. 3GPP Long-Term Evolution (LTE) is a 3GPP project aimed at improving the Universal Mobile Telecommunications System (UMTS) mobile phone standard. 3GPP can define specifications for next-generation mobile networks, mobile systems, and mobile devices. This disclosure focuses on the evolution from LTE, 4G, 5G, NR, and beyond wireless technologies, which have shared access to the radio spectrum among networks using a set of new and different radio access technologies or radio air interfaces.

[0039] 5G networks envision various deployments, various spectrums, and various services and devices that can be achieved using an OFDM-based unified 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: (1) massive Internet of Things (IoT) with ultra-high density (e.g., about 1M nodes / km^2), ultra-low complexity (e.g., about dozens of bits per 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 users with 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 a wide range of mobility or lack of mobility; and (3) enhanced mobile broadband, which includes extremely high capacity (e.g., about 10 Tbps / km^2), extreme data rates (e.g., multi-Gbps rates, 100+ Mbps user experience rate), and deep awareness with advanced discovery and optimization.

[0040] 5G NR devices, networks, and systems can be enabled to use optimized OFDM-based waveform features. These features can include: scalable parameter sets and transmission time intervals (TTIs); 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 in 5G NR (and the scaling of subcarrier spacing) can efficiently address operating diverse services across diverse spectrums and diverse deployments. For example, in various outdoor and macro coverage deployments with less than 3 GHz FDD / TDD implementations, the subcarrier spacing can occur at 15 kHz for bandwidths such as 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 for 80 / 100 MHz bandwidths. For various other indoor broadband implementations, by using TDD on the unlicensed portion of the 5 GHz band, the subcarrier spacing can occur at 60 kHz for 160 MHz bandwidths. Finally, for various deployments transmitting with mmWave components at 28 GHz TDD, the subcarrier spacing can occur at 120 kHz for 500 MHz bandwidths.

[0041] The scalable parameter sets of 5G NR enable 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 / downlink scheduling information, data, and acknowledgments in the same subframe. The self-contained integrated subframe supports communication in unlicensed or contention-based shared spectrums, supports 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.

[0042] For clarity, certain aspects of the devices and techniques may be described below with reference to exemplary LTE implementations or in an LTE-centric manner, and LTE terms may be used as illustrative examples in the following description; however, this description is not intended to be limited to LTE applications. In fact, the present disclosure is concerned with shared access to the radio spectrum between networks using different radio access technologies or radio air interfaces (such as those of 5G NR).

[0043] In addition, it should be understood that in operation, a wireless communication network adapted according to the concepts herein can operate using any combination of licensed or unlicensed spectrum depending on load and availability. Thus, it will be apparent to those skilled in the art that the systems, apparatuses, and methods described herein can be applied to other communication systems and applications different from the specific examples provided.

[0044] While aspects and embodiments are described in this application by way of illustration of some examples, those skilled in the art will understand that additional implementations and use cases can arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, packaging arrangements. For example, embodiments and / or uses can be generated via integrated chip embodiments and / or other non-module component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / shopping devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to particular use cases or applications, a wide applicability of the described innovations can occur. The scope of implementations can range from chip-level or module components to non-module, non-chip-level implementations and further to aggregated, distributed, or OEM devices or systems incorporating one or more of the described aspects. In some practical environments, devices incorporating the described aspects and features 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 / small devices of different sizes, shapes, and constitutions, chip-level components, multi-component systems (e.g., RF chains, communication interfaces, processors), distributed arrangements, end-user devices, etc.

[0045] Figure 1 A wireless network 100 for communication is shown according to some embodiments. The wireless network 100 can include, for example, a 5G wireless network. As will be appreciated by those skilled in the art, Figure 1 the components present are likely to have relevant counterparts in other network arrangements, including, for example, cellular network arrangements and non-cellular network arrangements (e.g., device-to-device or peer-to-peer or ad-hoc network arrangements, etc.).

[0046] Figure 1The wireless network 100 described in the present disclosure includes several base stations 105 and other network entities. A base station may be a station that communicates with a UE, and may also be referred to as an evolved Node B (eNB), a next-generation eNB (gNB), an access point, and so on. Each base station 105 provides communication coverage for a specific geographical area. In 3GPP, the term "cell" may refer to such a specific geographical coverage area of a base station and / 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 may be associated with the same operator or different operators (e.g., the wireless network 100 may include multiple operator wireless networks), and may use one or more frequencies in the same frequency as adjacent cells (e.g., 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 may be operated by more than one network operating entity. In other examples, each base station 105 and UE 115 may be operated by a single network operating entity.

[0047] 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 geographical area (e.g., with a radius of several kilometers), and may 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 may 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 (e.g., a residence), and in addition to unrestricted access, may also provide restricted access for UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in the residence, etc.). The base station of a macro cell may be referred to as a macro base station. The base station of 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 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 employ 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station, which may be a home node or a portable access point. A base station may support one or more (e.g., two, three, four, etc.) cells.

[0048] Wireless network 100 can support synchronous or asynchronous operations. For synchronous operations, each base station can have similar frame timing, and transmissions from different base stations can be approximately aligned in time. For asynchronous operations, each base station can have different frame timing, and transmissions from different base stations may not be aligned in time. In some scenarios, the network can be implemented or configured to handle dynamic switching between synchronous and asynchronous operations.

[0049] UEs 115 are dispersed throughout wireless network 100, and each UE can be stationary or mobile. It should be appreciated that although mobile devices are commonly 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 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, gaming devices, augmented reality devices, in-vehicle component devices / modules, or some other suitable term. Within this document, a "mobile" device or UE does not necessarily have to have the ability to move and can be stationary. Some non-limiting examples of mobile devices such as may include embodiments 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 can 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 use 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 (e.g., MP3 players), cameras, gaming 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 can be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, a UE can 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 1The UEs 115a - 115d in the illustrated embodiments are examples of mobile smart phone - type devices accessing the wireless network 100. The UEs can also be machines specifically configured for connected communication, including machine - type communication (MTC), enhanced MTC (eMTC), narrow - band IoT (NB - IoT), etc. Figure 1 The UEs 115e - 115k in the illustrated embodiments are examples of various machines configured for communication accessing the wireless network 100.

[0050] 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 it, lightning bolts (e.g., communication links) indicate wireless transmissions between the UE and the serving base station (the serving base station is the base station designated to serve the UE on the downlink and / or uplink), or desired transmissions between base stations, and backhaul transmissions between base stations. In some scenarios, the UE may operate as a base station or other network node. Backhaul communication between the base stations of the wireless network 100 may occur using wired and / or wireless communication links.

[0051] In the operation of the wireless 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).

[0052] The wireless network 100 of each embodiment 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, 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 the wireless network 100, or communicate via 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 via small cell base station 105f). The wireless network 100 can also provide additional network efficiency via dynamic, low-latency TDD / FDD communications, such as in a vehicle-to-vehicle (V2V) mesh network between UEs 115i - 115k communicating with macro base station 105e.

[0053] Figure 2 A block diagram showing the design of base station 105 and UE 115, which can be Figure 1 any one of the base stations and one of the UEs in Figure 1 For a restricted association scenario (as mentioned above), base station 105 can be Figure 2 small cell base station 105f in

[0054] At base station 105, transmit processor 220 may receive data from data source 212 and control information from controller / processor 240. This 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), 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 (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. Transmit processor 220 may also generate reference symbols, e.g., 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 (e.g., precoding) on the data symbols, control symbols, and / or reference symbols, if applicable, and may provide the output symbol streams to modulators (MOD) 232a through 232t. Each modulator 232 may process its 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 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.

[0055] At 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 (e.g., filter, amplify, down-convert, and digitize) its 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. MIMO detector 256 may obtain the received symbols from demodulators 254a through 254r, perform MIMO detection on the received symbols, if applicable, and provide detected symbols. Receive processor 258 may process (e.g., demodulate, de-interleave, and decode) the detected symbols, provide the decoded data for UE 115 to data sink 260, and provide the decoded control information to controller / processor 280.

[0056] On the uplink, at the UE 115, the transmit processor 264 may receive and process data from the data source 262 (e.g., data for the physical uplink shared channel (PUSCH)) and control information from the controller / processor 280 (e.g., control information for the 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 when 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 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 115. The processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240.

[0057] The controller / processors 240 and 280 may direct operations at the base station 105 and the UE 115, respectively. The controller / processor 240 at the base station 105 and / or other processors and modules and / or the controller / processor 280 at the UE 115 and / or other processors and modules may execute or direct the execution of various processes for the techniques described herein, such as executing or directing Figure 9 and Figure 10 the execution illustrated in

[0058] 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 specified shared spectrum for at least one period of time, and then another network operating entity may use the entire specified shared spectrum for a different period of time. Thus, to allow network operating entities to use the full specified shared spectrum and to mitigate interfering communications between different network operating entities, specific resources (e.g., time) may be partitioned and allocated to different network operating entities for specific types of communication.

[0059] For example, a particular time resource may be allocated to a network operating entity, and the particular time resource is reserved for the network operating entity to communicate exclusively using the entire shared spectrum. Other time resources may also be allocated to the network operating entity, where the entity has priority over other network operating entities to communicate using the shared spectrum. These time resources that are preferentially available for the network operating entity may be utilized by other network operating entities on an opportunistic basis when the prioritized network operating entity does not utilize these resources. Additional time resources to be used on an opportunistic basis may be allocated to any network operator.

[0060] The access to the shared spectrum and the arbitration of time resources among different network operating entities may be centrally controlled by a separate entity, autonomously determined through a predefined arbitration scheme, or dynamically determined based on the interaction between the wireless nodes of the network operator.

[0061] In some cases, UE 115 and base station 105 may operate in a shared radio frequency spectrum band, which may include licensed or unlicensed (e.g., contention-based) spectrum. In the unlicensed frequency portion of the shared radio frequency spectrum band, UE 115 or base station 105 may conventionally perform a medium sensing procedure to contend for access to the spectrum. For example, UE 115 or base station 105 may perform a listen-before-talk (LBT) procedure (such as a clear channel assessment (CCA)) before communication to determine whether the shared channel is available. CCA may include an energy detection procedure for determining whether there is any other active transmission. 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, signal power concentrated in a particular bandwidth and exceeding a predetermined noise floor may indicate another wireless transmitter. CCA may also include the detection of a specific sequence indicating channel usage. For example, another device may transmit a particular preamble before transmitting a data sequence. In some cases, the LBT procedure may include a wireless node adjusting its own backoff window as an agent against collisions based on the amount of energy detected on the channel and / or the acknowledgement / negative acknowledgement (ACK / NACK) feedback of its own transmitted packets.

[0062] Reference Figure 3 , depicts an illustrative example of a wireless communication system and is generally designated as 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, 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.

[0063] During operation, base station 105 and UE 115 are configured to communicate using one or more physical (PHY) channels 350. As an illustrative example, the one or more PHY channels 350 may include one or more of physical downlink shared channel (PDSCH) 352, physical uplink shared channel (PUSCH) 354, physical downlink control channel (PDCCH) 356, or physical uplink control channel (PUCCH) 358.

[0064] In some implementations, one or both of base station 105 and UE 115 may receive 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, base station 105 is configured to receive control information 302 from a service provider associated with wireless communication system 300. Base station 105 (or another base station) may be configured to provide control information 302 to UE 115 (e.g., via configuration message 320). Base station 105 may be configured to store control information 302 in memory 242, and UE 115 may be configured to store control information 302 in memory 282.

[0065] Control information 302 indicates one or more conditions 304 and one or more DMRS bundling 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 include a sharing condition 308. Figure 3 Examples also illustrate that the one or more DMRS bundling characteristics 314 may include a bundling characteristic 316 associated with the bundling condition 306. Alternatively or additionally, the one or more DMRS bundling characteristics 314 may include a sharing characteristic 318 associated with the sharing condition 308.

[0066] As used herein, DMRS bundling characteristics may refer to bundling of DMRS, sharing of DMRS, or both. DMRS sharing may refer to using DMRS transmitted during a first time slot to receive (e.g., demodulate) a signal transmitted during a second time slot, where no DMRS is transmitted during the second time slot (or where the DMRS transmitted during the second time slot is not used to receive the 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) the signal of the second time slot.

[0067] For further illustration, Figure 3Depicts that base station 105 and UE 115 can perform wireless communication 324 at least partially based on control information 302. The wireless communication 324 is transmitted using the one or more PHY channels 350 scheduled during multiple time slots 330. The wireless communication 324 includes one or more DMRSs, such as DMRS 340.

[0068] As used herein, a "time slot" (e.g., any one of the multiple time slots 336) can refer to any set of coherent 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 sub-frames, or any combination thereof. Additionally, a "full-duplex time slot" can refer to the 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.

[0069] Each time slot of the multiple time slots 330 can be associated with a resource configuration. An 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 of a time slot is a full-duplex configuration. In a full-duplex configuration, an uplink transmission and a downlink transmission can occur simultaneously during a time slot. In Figure 3 the example, the multiple time slots 330 include a first time slot 332 having a first full-duplex resource configuration 334 and further include a second time slot 336 having a second full-duplex resource configuration 338.

[0070] In some examples, the bundling characteristic 316 indicates enabling DMRS bundling during a time slot having a full-duplex resource configuration that meets the bundling condition 306. In some other examples, the bundling characteristic 316 indicates disabling DMRS bundling during a time slot having a full-duplex resource configuration that meets the bundling condition 306. Additionally, in some examples, the sharing characteristic 318 indicates enabling DMRS sharing during a time slot having a full-duplex resource configuration that meets the sharing condition 308. In some other examples, the sharing characteristic 318 indicates disabling DMRS sharing during a time slot having a full-duplex resource configuration that meets the sharing condition 308.

[0071] For further illustration, Figure 4 depicts an illustrative example of the wireless communication 324. In Figure 4 it, the wireless communication 324 is transmitted during multiple time slots. For illustration, in Figure 4 it, the wireless communication 324 is transmitted during time slots 402, 404, 406, and 408. In some implementations,Figure 3 Multiple time slots 330 thereof include time slots 402, 404, 406, and 408.

[0072] Each of the time slots 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 a half-duplex resource configuration 482. Time slots 404, 406, and 408 may be associated with full-duplex resource configurations 484, 486, and 488, respectively.

[0073] In some examples, the resource configuration may be changed dynamically during Figure 3 the 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 "switch" from a full-duplex configuration to a half-duplex configuration.

[0074] In Figure 4 the example, each of the time slots 402, 404, 406, and 408 may be associated with a downlink portion, such as the representative downlink portion 410 of time slot 404. In some examples, the downlink portion 410 includes data of a physical downlink shared channel (PDSCH). In addition, time slots 404, 406, and 408 may each include an uplink portion, such as the representative uplink portion 416 of time slot 404. In some examples, the uplink portion 416 includes data of a physical uplink shared channel (PUSCH). In Figure 4 the example, time slots 404, 406, and 408 include additional downlink portions, such as the representative downlink portion 418 of time slot 404. In some examples, the downlink portion 418 includes data of the PDSCH.

[0075] In some implementations, guard bands may be used to separate the uplink and downlink portions of the wireless communication 324. For example, Figure 4 illustration guard bands may separate the uplink and downlink portions of time slots 404, 406, and 408.

[0076] In some examples, the wireless communication 324 includes control information. For example, the downlink portion of the wireless communication 324 may include downlink control information, such as the representative downlink control information 412 of time slot 404. In some implementations, the uplink portion of the wireless communication 324 may include uplink control information, such as the representative uplink control information 422 of time slot 404.

[0077] In Figure 4In the example, each of resource configurations 482, 484, 486, and 484 may be associated with available bandwidth 450. The available bandwidth 450 may 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 herein as resource bandwidth. For example, the actual bandwidth 452 (e.g., resource bandwidth) for the downlink portion (e.g., downlink portion 410) of wireless communication 324 may be less than the available bandwidth 450.

[0078] In Figure 4 the example, the downlink portions of resource configurations 482, 484, 486, and 484 may have a common actual bandwidth (actual bandwidth 452). In Figure 4 it, the actual bandwidth 454 of the downlink portion of resource configuration 488 is less than the actual bandwidth 452 of the downlink portions of resource configurations 482, 484, and 486 (e.g., due to resource availability or other criteria).

[0079] One or more of resource configurations 482, 484, 486, and 484 may include DMRS. For example, downlink portion 410 may include DMRS 414, such as Figure 3 DMRS 340 of Figure 3 . In some examples, based on

[0080] control information 302 of Figure 3 , each time slot of wireless communication 324 includes or excludes DMRS.

[0081] For further illustration, in some examples, due to having downlink portions that include a common actual bandwidth 452, resource configurations 484, 486 satisfy the bundling condition 306 and the sharing condition 308. Thus, in some examples, resource configurations 484, 486 may share a common DMRS or may include bundled DMRS. In Figure 4 the example, the downlink portion of time slot 406 does not include DMRS and may share DMRS 414 with the downlink portion of time slot 404.

[0082] Additionally, in some examples, since the actual bandwidth 454 is different from the common actual bandwidth 452, the resource configuration 488 fails to meet the bundling condition 306 and the sharing condition 308. In such a case, the time slot 408 may include DMRS that is not shared or bundled with the time slots 404, 406.

[0083] In some implementations, the half-duplex resource configuration may be excluded from sharing, bundling, or both with a time slot. For example, in some implementations, the half-duplex resource configuration 482 is excluded from bundling, sharing, or both. In such a case, the downlink portion of the resource configuration 482 may include DMRS that is not shared or bundled with the downlink portions of the resource configurations 484, 486, and 488.

[0084] Figure 5 Another example of wireless communication 324 is depicted. In Figure 5 wireless communication 324 is transmitted during time slots 502, 504, 506, and 508. The 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 of

[0085] In some examples, Figure 5 one or more features of the wireless communication 324 of Figure 4 are as described with reference to

[0086] For further illustration, the time slot 508 may be used to convey the uplink portions 510 and 518 and the downlink portion 516. In Figure 5 the downlink portion 516 includes DMRS 522.

[0087] In Figure 5 the downlink portions of the resource configurations 582, 584, 586, and 588 are associated with a frequency boundary 550 (e.g., the high frequency boundary of the downlink portion) and a frequency boundary 552 (e.g., the low frequency boundary of the downlink portion). The downlink portion 516 is associated with a frequency boundary 552 (e.g., the high frequency boundary of the downlink portion 516) and a frequency boundary 556 (e.g., the low frequency boundary of the downlink portion 516).

[0088] According to some aspects of the present disclosure,Figure 3 One or more conditions 304 specify that a first frequency boundary of an uplink and a downlink portion of a first full-duplex resource configuration corresponds to a second frequency boundary of an uplink and a downlink portion of a second full-duplex resource configuration. For example, a bundling condition 306 may specify that bundling is enabled (or permitted) for two or more resource configurations of a wireless communication 324, and these resource configurations have a common frequency boundary for both the uplink portion and the downlink portion. Alternatively or additionally, a sharing condition 308 may specify that sharing is enabled (or permitted) for two or more resource configurations of a wireless communication 324, and these resource configurations have a common frequency boundary for both the uplink portion and the downlink portion.

[0089] For further illustration, in some examples, since the uplink and downlink portions have a common frequency boundary, resource configurations 582, 584, and 586 satisfy the bundling condition 306 and the sharing condition 308. For example, in Figure 5 , the downlink portions of resource configurations 582, 584, and 586 have a common frequency boundary 550, 552 and a common frequency boundary 556, 558. As another example, in Figure 5 , the uplink portions of resource configurations 582, 584, and 586 have a common frequency boundary 552, 556. Thus, in some examples, resource configurations 582, 584, and 586 may share a common DMRS or may include bundled DMRS. In Figure 4 's example, the downlink portions of resource configurations 584 and 586 do not include a DMRS and may share DMRS 414 with resource configuration 582.

[0090] Furthermore, in some examples, since it has a downlink frequency boundary different from the downlink frequency boundaries of resource configurations 582, 584, and 586, since it has an uplink frequency boundary different from the uplink frequency boundaries of resource configurations 582, 584, and 586, or both, resource configuration 588 fails to satisfy the bundling condition 306 and the sharing condition 308. For illustration, in Figure 5 , the downlink portion 516 has a frequency boundary 552, 556 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 , the uplink portions 510, 518 have a frequency boundary 550, 552 and 556, 558 different from the frequency boundary 552, 556 of the uplink portions of resource configurations 582, 584, and 586. Accordingly, resource configuration 588 may include a DMRS 522 that is not shared or bundled with resource configurations 582, 584, and 586.

[0091] Figure 6 depicts another example of wireless communication 324. In Figure 6 this, wireless communication 324 occurs during time slots 602, 604, 606, and 608. Time slots 602, 604, 606, and 608 are respectively associated with full-duplex resource configurations 682, 684, 686, and 688. In some implementations, Figure 3 a plurality of time slots 330 of

[0092] include time slots 602, 604, 606, and 608. Figure 5 In some examples, Figure 4 one or more features of wireless communication 324 of

[0093] are as described with reference to

[0094] For further illustration, time slot 606 can be used to convey downlink portions 610 and 618 and uplink portion 616. Time slot 608 can be used to convey downlink portions 620, 628 and uplink portion 626. Figure 3 According to some aspects of the present disclosure,

[0095] For illustration, in Figure 6 this, downlink portions 410, 610, and 620 have a common frequency boundary 650, 654. Figure 6It is also explained that the uplink portions 416, 616 have frequency boundaries 651, 652 and 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 share with each other, beamform with each other, or both, and further indicates that the uplink portions 416, 616 are eligible to share with each other, beamform with each other, or both. In Figure 6 this case, the DMRS 414 can be shared among the downlink portions 410, 610, and 620.

[0096] The control information 302 can indicate that the uplink portion 626 is not eligible to share with, beamform with, or both with respect to the uplink portions 416, 616 of the time slots 604, 606. Additionally, the control information 302 can indicate that the downlink portions 618, 418 are eligible to share with each other, beamform with each other, or both, and indicate that the downlink portion 628 is not eligible to share with, not eligible to beamform with, or both with the downlink portions 418, 618.

[0097] Figure 7 Another example of wireless communication 324 is depicted. In Figure 7 this example, the wireless communication 324 occurs during the time slots 702, 704, 706, 708, 710, 712, and 714. The time slots 704, 706, 710, and 712 can respectively include downlink portions 410, 715, 720, and 730. The time slots 704, 706, 710, and 712 can be respectively associated with full-duplex resource configurations 784, 786, 790, and 792. In some implementations, Figure 3 the plurality of time slots 330 includes the time slots 702, 704, 706, 708, 710, 712, and 714.

[0098] In some aspects of the present disclosure, Figure 3 one or more conditions 304 of this specify that a first time slot is adjacent in time to a second time slot. In this example, time slots that are adjacent in time can be eligible to share, beamform, or both, while time slots that are not adjacent in time may not be eligible to share, beamform, or both.

[0099] For illustration, in Figure 7 this case, the time slot 704 is adjacent in time to the time slot 706. Accordingly, in some aspects of the present disclosure, the downlink portion 410 is eligible to share with, beamform with, or both with the downlink portion 715. In Figure 7In the example of, DMRS 414 can be shared between downlink portions 410 and 715. Alternatively or additionally, downlink portion 410 can include DMRS 714 that is shared between downlink portions 410 and 715.

[0100] 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, bundled with, or both, with downlink portion 730. In Figure 7 's example, downlink portion 720 can include DMRS 724 that is shared between downlink portions 720 and 730. Alternatively or additionally, downlink portion 720 can include DMRS 734 that is shared between downlink portions 720 and 730.

[0101] For further illustration, time slots 706 and 710 are non - adjacent in time (e.g., due to time slot 708 occurring between time slots 706 and 710). As a result, in some examples, downlink portions 715 and 720 are not eligible to be shared, bundled, or both.

[0102] In addition, although certain conditions are described separately herein for convenience, it should be appreciated that two or more of the conditions described herein can be combined. In one example, the one or more conditions 304 can be combined with Figure 4 one or more of the conditions in, combined with Figure 5 one or more of the conditions in, combined with Figure 6 one or more of the conditions in, or a combination thereof, to specify the Figure 4 conditions.

[0103] Figure 8 Depicts another example of wireless communication 324. In Figure 8 's example, wireless communication 324 includes time slots 802, 804, 806, and 808. Time slots 802, 804, 806, and 808 are respectively associated with full - duplex resource configurations 892, 894, 896, and 898. Time slots 804, 806, and 808 can respectively include downlink portions 410, 810, and 820. In some implementations, Figure 3 the plurality of time slots 330 of includes time slots 802, 804, 806, and 808.

[0104] In Figure 8In the example, each of the downlink portions 410, 810, and 820 may have an actual bandwidth different from that of the other downlink portions 410, 810, and 820. For example, the downlink portion 410 may have an actual bandwidth of 882. The downlink portion 810 may have an actual bandwidth of 882 different from (e.g., less than) the actual bandwidth of 884. The downlink portion 820 may have an actual bandwidth different from (e.g., greater than) the actual bandwidth of 882 and the actual bandwidth of 884.

[0105] According to some aspects of the present disclosure, Figure 3 one or more conditions 304 of specify one or more criteria among time slots associated with resource configurations having different actual bandwidths, such as actual bandwidths 882, 884, and 886. In accordance with Figure 8 a first example of, Figure 3 one or more conditions 304 of specify that the first bandwidth of 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 second bandwidth is greater than or equal to the third bandwidth of the third downlink portion of the third full-duplex resource configuration. In the first example, if the actual bandwidth of the downlink portion does not increase from one time slot to a subsequent time slot, the downlink portion may be eligible for sharing or bundling.

[0106] For illustration, according to the first example, the downlink portion 810 may be eligible for bundling or sharing with the downlink portion 410 because the actual bandwidth 882 is greater than or equal to the actual bandwidth 884. According to the first example, the downlink portion 820 may not be eligible for sharing with the downlink portions 410, 410 because the actual bandwidth 886 is greater than the actual bandwidth 884 of time slot 806.

[0107] In accordance with Figure 8 a second example of, Figure 3 one or more conditions 304 of 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 the second example, if the initial time slot of the set has an actual bandwidth of the downlink portion greater than the actual bandwidth of the subsequent time slots of the set, the downlink portion may be eligible for sharing or bundling.

[0108] For illustration, according to the second example, the downlink portions 410, 810, and 820 may not be eligible for sharing or bundling because the actual bandwidth 882 of the downlink portion 410 is not greater than or equal to the actual bandwidth 886 of the downlink portion 820. In another implementation of the second example, the downlink portion 810 may be eligible for sharing or bundling with the downlink portion 410 (because the actual bandwidth 884 is less than the actual bandwidth 884), and the downlink portion 820 may not be eligible for sharing or bundling with the downlink portions 410, 810 (because the actual bandwidth 886 is greater than the actual bandwidths 882, 884).

[0109] In a third example according to Figure 8 one or more conditions 304 of Figure 3 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 the third example, if the time slots have a common actual bandwidth, the downlink portions of the set of time slots may be eligible for sharing or bundling.

[0110] For illustration, in an example according to Figure 8 the downlink portions 410, 810, and 820 do not have a common actual bandwidth. As a result, the downlink portions 410, 810, and 820 may not be eligible for sharing, bundling, or both. In some other examples, the downlink portions 410, 810, and 820 may have a common actual bandwidth and may be eligible for sharing, bundling, or both.

[0111] Although certain examples of Figures 4 - 8 have been described with reference to downlink operations, such operations may be performed in conjunction with uplink operations (as a replacement or supplement to downlink operations). For example, the bundling and sharing operations described herein may be performed in conjunction with PDSCH communication, PUSCH communication, PUCCH communication, PDCCH communication, other communication, or a combination thereof.

[0112] For further illustration, in some aspects of the present disclosure, an example of full-duplex communication is sub-band frequency-division duplexing (SBFDD) communication, which may also be referred to as a flexible duplexing communication technique. 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 transmit and receive signals simultaneously. Another example of full-duplex communication is in-band full-duplex (IBFD) communication, which may involve using common time and frequency resources (e.g., where time resources partially or fully overlap with frequency resources) to transmit and receive signals simultaneously.

[0113] In some implementations, a component carrier bandwidth (CC BW) can be used to perform SBFDD communication. For example, referring to Figures 4 - 8 each wireless communication 324 illustrated can correspond to an SBFDD wireless communication having a frequency range (illustrated as the vertical axis) corresponding to the CC BW. In some implementations, the CC BW has an uplink bandwidth part (BWP) of 20 MHz and a downlink BWP of 80 MHz. In other implementations, different bandwidth partitions can be used (e.g., as an illustrative example, depending on interference between the base station and other devices).

[0114] Within an active BWP, different resource bandwidths (BW) can be defined, and different BW can be dynamically assigned or indicated. In some examples, downlink control information (DCI) is used to indicate the resource BW. Alternatively or additionally, the resource BW can be configured via radio resource control (RRC). Depending on the example, the resource BW can be contiguous or non - overlapping. In some cases, frequency - domain resource allocation (FDRA) can be performed per resource bandwidth and can use fewer bits compared to the BWP. In some cases, the uplink and downlink can have different resource BW configurations. Additionally, each resource BW can be associated with a corresponding configuration, such as a resource block group (RBG). The uplink and downlink resource BW can be non - overlapping (such as in combination with SBFDD communication) or partially overlapping (such as in combination with IBFD communication). In some examples, "zero - latency" switching between resource BW can be implemented.

[0115] In some aspects of the present disclosure, one or more of DMRS sharing or DMRS bundling can be performed across transmissions (or repetitions of the same transmission) that comply with one or more conditions in a full-duplex system. These conditions can 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 can further specify that PxyCH will be transmitted in a full-duplex (FD) time slot with the same active BWP and the same resource BW. In a variant of the first example, in the case of multiple resource BWs, then these conditions can further specify that the downlink and uplink frequency domain portions of the resource BW will be the same. In a second example, these conditions can further specify that PxyCH will be transmitted in time slots with the same downlink (or uplink) frequency domain boundary (while allowing a change in the uplink (or downlink) frequency domain boundary between PxyCH). In a third option, these conditions further specify that PxyCH complies with the conditions of the first example, the second example, or both, and also specifies that PxyCH are adjacent to each other (e.g., there are no time slots between PxyCH that can have different downlink boundaries, uplink boundaries, or both). In some implementations, the first example corresponds to Figure 4 the example of Figure 5 the variant of the first example corresponds to Figure 6 the example of Figure 7 the second example corresponds to

[0116] the example of

[0117] In some implementations, the base station 105 can configure one or more of these capabilities for the UE 115. For example, the base station 105 can transmit an indication of one or more of these capabilities to the UE 115 in a DMRS sharing or bundling configuration message.

[0118] 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 it is desirable for UE 115 to beamform 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 optionally (or may not) beamform PxyCH.

[0119] Reference Figure 9 , depicts an illustrative example of a method and is generally designated as 900. In some examples, the operations of method 900 are performed by a UE device (such as UE 115).

[0120] Method 900 includes: at 902, receiving, by the UE device, control information that indicates conditions associated with DMRS bundling characteristics of DMRS to be wirelessly communicated using one or more PHY channels. For example, UE 115 may receive control information 302 that indicates the one or more conditions 304 and the one or more DMRS bundling characteristics 314. In some examples, the one or more PHY channels 350 include one or more of PDSCH 352, PUSCH 354, PDCCH 356, or PUCCH 358.

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 one of time slots 332, 336, 404 - 408, 502 - 508, 604 - 608, 704 - 714, and 804 - 808.

[0122] In some examples, the wireless communication corresponds to wireless communication 324. For further illustration, in some examples, performing the wireless communication includes transmitting the DMRS to a base station based on the DMRS grouping characteristic. For example, UE 115 may transmit any one of DMRS 414, 522, 714, 724, or 734 to 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 a base station based on the DMRS grouping characteristic. For example, UE 115 may receive any one of DMRS 414, 522, 714, 724, or 734 from base station 105 based on the one or more DMRS grouping characteristics 314.

[0123] Reference Figure 10 , an illustrative example of a method is depicted and generally designated as 1000. In some examples, the operations of method 1000 are performed by a base station device such as base station 105.

[0124] Method 1000 includes: at 1002, receiving, by a base station, control information that indicates a condition associated with a DMRS grouping characteristic of a DMRS to be wirelessly communicated using one or more PHY channels. For example, base station 105 may receive control information 302 that indicates 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 PDSCH 352, PUSCH 354, PDCCH 356, or PUCCH 358. In some examples, the DMRS corresponds to any one of DMRS 340, 414, 522, 714, 724, or 734.

[0125] Method 1000 further includes: at 1004, in response to a first full-duplex resource configuration associated with a first time slot among a plurality of time slots of wireless communication and a second full-duplex resource configuration associated with a second time slot among the plurality of time slots satisfying the condition, performing wireless communication based on the DMRS grouping characteristics indicated by the control information. 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 one 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 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 one of full-duplex resource configurations 334, 338, 484 - 488, 582 - 588, 684 - 688, 784 - 792, and 892 - 898.

[0126] In some examples, the wireless communication corresponds to wireless communication 324. For further illustration, in some examples, performing the wireless communication includes transmitting the DMRS to the UE device based on the DMRS grouping characteristics. For example, base station 105 may transmit any one of DMRS 414, 522, 714, 724, or 734 to 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 characteristics.
