[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 044,181, filed on June 25, 2020, entitled “TRANSMISSION CONFIGURATIONS IN FULL DUPLEX MODE,” and U.S. Non-Provisional Patent Application No. 17 / 320,612, filed on May 14, 2021, entitled “TRANSMISSION CONFIGURATIONS IN FULL DUPLEX MODE,” both of which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communications and techniques and apparatus for activating and using a transmission configuration for full-duplex mode. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcast. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include many base stations (BSs) that may support communications for many user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or forward link) refers to a communication link from a BS to a UE, and an "uplink" (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmission reception point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at municipal, national, regional and even global levels. NR, also known as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements in LTE, NR and other radio access technologies remain very useful. Summary of the invention

[0027] Aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be understood as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully transmitted to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is realized independently of any other aspect of the present disclosure or realized in combination with any other aspect of the present disclosure. For example, any number of aspects stated herein can be used to realize a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods that are practiced using other structures, functionality, or structures and functionality in addition to or different from the various aspects of the disclosure stated herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0028] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0029] It should be noted that although terms generally associated with 5G or NR radio access technologies (RATs) may be used herein to describe various aspects, various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0030] Figure 1 is a diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, TRP, etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving this coverage area, depending on the context in which the term is used.

[0031] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5GNB", and "cell" may be used interchangeably herein.

[0032] In some aspects, the cell may not necessarily be fixed, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some examples, the BSs may be interconnected with each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0033] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay BS 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay BS may also be referred to as a relay station, a relay base station, a repeater, or the like.

[0034] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmission power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmission power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmission power level (e.g., 0.1 to 2 watts).

[0035] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other, for example, directly or indirectly via a wireless or wired backhaul.

[0036] UE 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle-mounted component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0037] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or positioning tags, etc., which may communicate with a base station, another device (e.g., a remote device) or some other entity. For example, a wireless node may provide connectivity to a network or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0038] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0039] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary for mutual communication) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol or vehicle-to-infrastructure (V2I) protocol) and / or mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0040] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1) from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2) from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "below 6 GHz" band. Similarly, FR2 is also often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, it can be widely referred to as a frequency less than 6 GHz, a frequency within FR1, and / or a mid-band frequency (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, it can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0041] As indicated above, provide Figure 1 As an example. Other examples may be related to Figure 1 Different than described.

[0042] Figure 2 is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0043] At the base station 110, the transmission processor 220 can receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmission processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmission processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0044] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284 .

[0045] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0046] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included in one or more antenna panels, antenna groups, a group of antenna elements, and / or antenna arrays, etc. The antenna panel, antenna group, a group of antenna elements, and / or antenna array may include one or more antenna elements. The antenna panel, antenna group, a group of antenna elements, and / or antenna array may include a group of coplanar antenna elements and / or a group of non-coplanar antenna elements. The antenna panel, antenna group, a group of antenna elements, and / or antenna array may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panel, antenna group, a group of antenna elements, and / or antenna array may include one or more antenna elements coupled to one or more transmission and / or reception components, such as Figure 2 One or more components of a

[0047] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., reference numerals 284, 285, 286, 287, 288, 289, 290, 300, 311, 321, 332, 343, 357, 368, 370, 380, 390, 409, 410, 421, 434, 443, 459, 460, 471, 481 Figure 5A-8 ).

[0048] At the base station 110, uplink signals from the UE 120 and other UEs 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 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., reference 200 to FIG. 1 ).

[0049] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the base station 110 may perform one or more techniques associated with activating and using a transmission configuration for full-duplex mode, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 7 The process 700 Figure 8 800 and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 7 The process 700 Figure 8 The operations of process 800 and / or other processes described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among others.

[0050] In some aspects, a UE (e.g., UE 120) may include: a means for receiving control information indicating at least two TCI states from a base station (e.g., base station 110), wherein a first TCI state of the at least two TCI states is associated with a half-duplex mode of the UE, and a second TCI state of the at least two TCI states is associated with a full-duplex mode of the UE; and / or a means for receiving a downlink transmission according to at least one of the first TCI state or the second TCI state from the base station. Means for the UE to perform operations described herein may include, for example, one or more of an antenna 252, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a modulator 254, a controller / processor 280, or a memory 282.

[0051] In some aspects, a base station (e.g., base station 110) may include: a component for transmitting control information indicating at least two TCI states to a UE (e.g., UE 120), wherein a first TCI state of the at least two TCI states is associated with a half-duplex mode of the UE, and a second TCI state of the at least two TCI states is associated with a full-duplex mode of the UE; and / or a component for transmitting a downlink transmission according to the first TCI state or the second TCI state to the UE. The components for the base station to perform the operations described herein may include, for example, one or more of the transmit processor 220, the TX MIMO processor 230, the modulator 232, the antenna 234, the demodulator 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0052] Although Figure 2 The blocks in the diagram are shown as distinct components, but the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0053] As indicated above, provide Figure 2 As an example. Other examples may be related to Figure 2 Different than described.

[0054] Figure 3 is a diagram illustrating an example of a beamforming architecture 300 that supports beamforming for mmW communications according to the present disclosure. In some aspects, the architecture 300 can implement aspects of the wireless network 100. In some aspects, the architecture 300 can be implemented in a transmitting device (e.g., a first wireless communication device, UE, or base station) and / or a receiving device (e.g., a second wireless communication device, UE, or base station), as described herein.

[0055] In summary, Figure 3 300 is a diagram illustrating exemplary hardware components of a wireless communication device according to certain aspects of the present disclosure. The components shown may include components that can be used for antenna element selection and / or beamforming for wireless signal transmission. There are many architectures for antenna element selection and implementing phase shifting, only one example of which is shown herein. Architecture 300 includes a modem (modulator / demodulator) 302, a digital-to-analog converter (DAC) 304, a first mixer 306, a second mixer 308, and a separator 310. Architecture 300 also includes a plurality of first amplifiers 312, a plurality of phase shifters 314, a plurality of second amplifiers 316, and an antenna array 318 including a plurality of antenna elements 320.

[0056] Transmission lines or other waveguides, conductors, and / or traces are shown connecting the various components to illustrate how signals to be transmitted propagate between the components. Reference numerals 322, 324, 326, and 328 indicate areas in the architecture 300 where different types of signals propagate or are processed. Specifically, reference numeral 322 indicates an area in which digital baseband signals propagate or are processed, reference numeral 324 indicates an area in which analog baseband signals propagate or are processed, reference numeral 326 indicates an area in which analog intermediate frequency (IF) signals propagate or are processed, and reference numeral 328 indicates an area in which analog radio frequency (RF) signals propagate or are processed. The architecture also includes local oscillator A 330, local oscillator B 332, and a controller / processor 334. In some aspects, controller / processor 334 corresponds to the above description of the controller / processor. Figure 2 The controller / processor 240 of the base station described above and / or Figure 2 A controller / processor 280 of a UE is depicted.

[0057] Each of the antenna elements 320 may include one or more sub-elements for radiating or receiving RF signals. For example, a single antenna element 320 may include a first sub-element that is cross-polarized with a second sub-element, and the second sub-element may be used to independently transmit a cross-polarized signal. The antenna elements 320 may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or other patterns. The spacing between the antenna elements 320 may allow the signals with the desired wavelengths transmitted by the antenna elements 320 to interact or interfere (e.g., form a desired beam). For example, given an expected range of wavelengths or frequencies, the spacing may provide a quarter wavelength, half a wavelength, or other fractions of a wavelength of the spacing between adjacent antenna elements 320 to allow interaction or interference of signals transmitted by separate antenna elements 320 within the expected range.

[0058] The modem 302 processes and generates a digital baseband signal, and may also control the operation of the DAC 304, the first and second mixers 306 and 308, the separator 310, the first amplifier 312, the phase shifter 314, and / or the second amplifier 316 to transmit the signal via one or more or all of the antenna elements 320. The modem 302 may process the signal and control the operation according to a communication standard (such as the wireless standard discussed herein). The DAC 304 may convert the digital baseband signal received from the modem 302 (and to be transmitted) into an analog baseband signal. The first mixer 306 uses the local oscillator A 330 to up-convert the analog baseband signal into an analog IF signal within the IF. For example, the first mixer 306 may mix the signal with the oscillating signal generated by the local oscillator A 330 to "move" the baseband analog signal to the IF. In some cases, some processing or filtering (not shown) may occur at the IF. The second mixer 308 uses the local oscillator B 332 to up-convert the analog IF signal into an analog RF signal. Similar to the first mixer, the second mixer 308 can mix the signal with an oscillating signal generated by the local oscillator B 332 to "move" the IF analog signal to the RF or frequency at which the signal is to be transmitted or received. The modem 302 and / or the controller / processor 334 can adjust the frequency of the local oscillator A 330 and / or the local oscillator B 332 to produce the desired IF and / or RF frequency and to facilitate the processing and transmission of signals within the desired bandwidth.

[0059] In the illustrated architecture 300, the signal up-converted by the second mixer 308 is separated or copied into multiple signals by the separator 310. The separator 310 in the architecture 300 separates the RF signal into multiple identical or nearly identical RF signals. In other examples, separation can occur on any type of signal, including baseband digital, baseband analog or IF analog signals. Each of these signals can correspond to an antenna element 320, and the signal is propagated and processed by amplifiers 312 and 316, phase shifters 314 and / or other elements corresponding to the corresponding antenna element 320 to be provided to and transmitted by the corresponding antenna element 320 of the antenna array 318. In one example, the separator 310 can be an active splitter, which is connected to a power supply and provides some gain so that the power level of the RF signal leaving the separator 310 is equal to or greater than the signal entering the separator 310. In another example, the separator 310 is a passive separator that is not connected to a power supply, and the RF signal leaving the separator 310 can be at a lower power level than the RF signal entering the separator 310.

[0060] After being separated by the separator 310, the resulting RF signal can enter an amplifier, such as a first amplifier 312 or a phase shifter 314 corresponding to the antenna element 320. The first amplifier 312 and the second amplifier 316 are shown with dashed lines, respectively, because one or both of them may not be necessary in some aspects. In some aspects, there are both the first amplifier 312 and the second amplifier 316. In some aspects, there is neither the first amplifier 312 nor the second amplifier 316. In some aspects, one of the two amplifiers 312 and 316 exists, but the other does not exist. For example, if the separator 310 is an active separator, the first amplifier 312 may not be used. As another example, if the phase shifter 314 is an active phase shifter that can provide gain, the second amplifier 316 may not be used.

[0061] Amplifiers 312 and 316 can provide a desired level of positive or negative gain. Positive gain (positive dB) can be used to increase the amplitude of a signal for radiation by a particular antenna element 320. Negative gain (negative dB) can be used to reduce the amplitude and / or suppress the radiation of a signal through a particular antenna element. Each of amplifiers 312 and 316 can be independently controlled (e.g., by modem 302 or controller / processor 334) to provide independent gain control for each antenna element 320. For example, modem 302 and / or controller / processor 334 can have at least one control line connected to each of separator 310, first amplifier 312, phase shifter 314, and / or second amplifier 316, which can be used to configure gain so as to provide a desired amount of gain for each component and therefore each antenna element 320.

[0062] The phase shifter 314 can provide a configurable phase shift or phase offset to the corresponding RF signal to be transmitted. The phase shifter 314 can be a passive phase shifter that is not directly connected to the power supply. The passive phase shifter may introduce some insertion loss. The second amplifier 316 can enhance the signal to compensate for the insertion loss. The phase shifter 314 can be an active phase shifter connected to the power supply so that the active phase shifter provides a certain amount of gain or prevents insertion loss. The setting of each phase shifter 314 is independent, meaning that each can be independently set to provide a desired phase shift amount or the same phase shift amount or some other configuration. The modem 302 and / or the controller / processor 334 can have at least one control line connected to each phase shifter 314, and the control line can be used to configure the phase shifter 314 to provide a desired phase shift amount or phase offset amount between the antenna elements 320.

[0063] In the illustrated architecture 300, the RF signal received by the antenna element 320 is provided to one or more first amplifiers 356 to enhance the signal strength. The first amplifier 356 can be connected to the same antenna array 318 (e.g., for time division duplex (TDD) operation). The first amplifier 356 can be connected to different antenna arrays 318. The enhanced RF signal is input into one or more phase shifters 354 to provide a configurable phase shift or phase offset for the corresponding received RF signal to achieve reception via one or more Rx beams. The phase shifter 354 can be an active phase shifter or a passive phase shifter. The setting of the phase shifter 354 is independent, meaning that each can be independently set to provide a desired phase shift amount or the same phase shift amount or some other configuration. The modem 302 and / or the controller / processor 334 can have at least one control line connected to each phase shifter 354, and the control line can be used to configure the phase shifter 354 to provide a desired phase shift amount or phase offset between the antenna elements 320, thereby achieving reception via one or more Rx beams.

[0064] The output of phase shifter 354 can be input to one or more second amplifiers 352 for signal amplification of the phase-shifted received RF signal. Second amplifier 352 can be configured individually to provide a configured gain amount. Second amplifier 352 can be configured individually to provide a gain amount to ensure that the signal input to combiner 350 has the same magnitude. Amplifier 352 and / or 356 are shown with dotted lines because they may not be necessary in some aspects. In some aspects, there are both amplifier 352 and amplifier 356. On the other hand, there is neither amplifier 352 nor amplifier 356. In other aspects, one of amplifiers 352 and 356 exists, but the other does not exist.

[0065] In the illustrated architecture 300, the signals output by the phase shifter 354 are combined (via the amplifier 352, when present) in the combiner 350. The combiner 350 in the architecture 300 combines the RF signals into one signal. The combiner 350 can be a passive combiner (e.g., not connected to a power source), which may result in some insertion loss. The combiner 350 can be an active combiner (e.g., connected to a power source), which may result in some signal gain. When the combiner 350 is an active combiner, it can provide a different (e.g., configurable) amount of gain for each input signal so that the input signals have the same magnitude when combined. When the combiner 350 is an active combiner, the combiner 350 may not need a second amplifier 352, because the active combiner can provide signal amplification.

[0066] The output of combiner 350 is input to mixers 348 and 346. Mixers 348 and 346 typically downconvert the received RF signal using inputs from local oscillators 372 and 370, respectively, to create intermediate or baseband signals that carry coding and modulation information. The output of mixers 348 and 346 is input to analog-to-digital converter (ADC) 344 for conversion to analog signals. The analog signal output from ADC 344 is input to modem 302 for baseband processing, such as decoding, deinterleaving, or similar operations.

[0067] The architecture 300 is given by way of example only to illustrate an architecture for transmitting and / or receiving signals. In some cases, the architecture 300 and / or each part of the architecture 300 can be repeated multiple times within an architecture to accommodate or provide any number of RF chains, antenna elements and / or antenna panels. In addition, many alternative architectures are possible and expected. For example, although only a single antenna array 318 is shown, two, three or more antenna arrays may be included, each with one or more of their own corresponding amplifiers, phase shifters, separators, mixers, DACs, ADCs and / or modems. For example, a single UE may include two, four or more antenna arrays for transmitting or receiving signals at different physical locations on the UE or in different directions.

[0068] In addition, in the architecture of different implementations, mixers, separators, amplifiers, phase shifters and other components can be located in different signal type areas (e.g., represented by different reference numerals in reference numerals 322, 324, 326 and 328). For example, in different examples, the signal to be transmitted can be divided into multiple signals at analog RF, analog IF, analog baseband or digital baseband frequencies. Similarly, amplification and / or phase shifting can also occur at different frequencies. For example, in some aspects, one or more of separator 310, amplifiers 312 and 316 or phase shifter 314 can be positioned between DAC 304 and first mixer 306 or between first mixer 306 and second mixer 308. In one example, the functions of one or more components can be combined into one component. For example, phase shifter 314 can perform amplification to include or replace first amplifier 312 and / or second amplifier 316. As another example, phase shifting can be implemented by second mixer 308 to avoid the need for separate phase shifter 314. This technique is sometimes referred to as local oscillator (LO) phase shifting. In some aspects of this configuration, there may be multiple IF to RF mixers within the second mixer 308 (e.g., for each antenna element chain), and local oscillator B 332 may provide a different local oscillator signal (with a different phase offset) to each IF to RF mixer.

[0069] The modem 302 and / or the controller / processor 334 can control one or more other components 304 to 372 to select one or more antenna elements 320 and / or form a beam for transmitting one or more signals. For example, by controlling the amplitude of one or more corresponding amplifiers (such as the first amplifier 312 and / or the second amplifier 316), the antenna elements 320 can be individually selected or deselected for transmission of a signal (or multiple signals). Beamforming includes generating a beam using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are phase-shifted relative to each other. The formed beam can carry a physical or higher-level reference signal or information. When each of the multiple signals is radiated from the respective antenna element 320, the radiated signals interact, interfere (constructively and destructively) and amplify each other to form the resulting beam. By modifying the phase shift or phase offset imparted by the phase shifter 314 and the amplitude of the multiple signals imparted by the amplifiers 312 and 316 relative to each other, the shape (such as, the amplitude, width and / or the presence of side lobes) and direction (such as, the angle of the beam relative to the surface of the antenna array 318) can be dynamically controlled. The controller / processor 334 may be located partially or completely within one or more other components of the architecture 300. For example, in some aspects, the controller / processor 334 may be located within the modem 302.

[0070] As indicated above, provide Figure 3 As an example. Other examples may be related to Figure 3 Different than described.

[0071] Figure 4A , Figure 4B and Figure 4C 4 and 420 are diagrams showing examples of full-duplex communication, respectively. Figures 4A-4C As shown, examples 400, 410, and 420 each include one or more UEs 402 communicating with one or more base stations (or TRPs) 404 in a wireless network supporting full-duplex communication. However, it should be understood that Figures 4A-4C The devices shown in the figure are provided as examples only, and the wireless network may support full-duplex communication between other devices (e.g., between a mobile terminal (MT) node and a control node (e.g., a central unit (CU) or a distributed unit (DU)), between a child node and a parent node in an integrated access backhaul (IAB) network, and / or between a scheduled node and a scheduling node).

[0072] like Figure 4A As shown in FIG. 4 , example 400 includes a UE 402 in communication with two base stations (or TRPs) 404-1 and 404-2. Figure 4AAs shown in FIG. 4 , UE 402 may transmit one or more uplink transmissions to base station 404-1 and may simultaneously receive one or more downlink transmissions from base station 404-2. Figure 4A In the illustrated example 400, full-duplex communication is enabled for UE 402, which may operate as a full-duplex node, but full-duplex communication is not enabled for base stations 404-1 and 404-2, which may operate as half-duplex nodes. Additionally or alternatively, as Figure 4B As shown in , example 410 includes two UEs, UE1 402-1 and UE2 402-2, communicating with a base station (or TRP) 404. In this case, the base station 404 can transmit one or more downlink transmissions to UE1 402-1 and can simultaneously receive one or more uplink transmissions from UE2 402-2. Figure 4B In the illustrated example 410, full-duplex communication is enabled for the base station 404, and the base station 404 can operate as a full-duplex node, but full-duplex communication is not enabled for UE1 402-1 and UE2 402-2, and UE1 402-1 and UE2 402-2 can operate as half-duplex nodes. In addition or alternatively, as Figure 4C As shown in , example 420 includes a UE 402 in communication with a base station (or TRP) 404. In this case, the base station 404 can transmit and the UE 402 can receive one or more downlink transmissions, while the UE 402 transmits and the base station 404 receives one or more uplink transmissions. Figure 4C In the illustrated example 420, full-duplex communication is enabled for both the UE 402 and the base station 404, each of which may operate as a full-duplex node.

[0073] Utilizing full-duplex communication provides reduced latency by allowing full-duplex nodes to transmit or receive downlink signals in uplink-only time slots and / or transmit or receive uplink signals in downlink-only time slots. In addition, full-duplex communication enhances spectral efficiency and / or network throughput (e.g., on a per-cell and / or per-UE basis), which results in more efficient resource utilization by using time and frequency resources for uplink and downlink communications simultaneously.

[0074] As shown above, Figures 4A-4C are provided as examples. Other examples may be related to Figures 4A-4C Different than described.

[0075] Figure 4D 4 is a diagram showing another example 430 of full-duplex communication. Figure 4DAs shown in , example 430 includes a wireless network that supports full-duplex communication (e.g., Figure 1 UE 402 in communication with a base station (e.g., gNB 404) or another type of TRP in a wireless network 100. However, it should be understood that Figure 4D The devices shown in are provided as examples only, and the wireless network may support full-duplex communication between other devices (eg, between an MT node and a control node, between a child node and a parent node in an IAB network, and / or between a scheduled node and a scheduling node).

[0076] like Figure 4D As shown, UE 402 may experience self-interference (SI) between uplink communications to gNB 404 and downlink communications from gNB 404. Similarly, gNB 404 may experience SI between uplink communications from UE 402 and downlink communications to UE 402. In some aspects, SI may be caused by time and / or frequency overlap between uplink communications and downlink communications (e.g., as described below with respect to FIG. 1 ). Figure 5A Additionally or alternatively, SI may be caused by little or no guard time and / or frequency between uplink and downlink communications (e.g., as described below with respect to Figure 5B-5C described).

[0077] Thus, full-duplex communication may be performed by selecting appropriate uplink and downlink beam pairs (e.g., transmit and receive beams associated with different antenna panels of the UE and / or associated with different antenna panels and / or TRPs of the base station) to reduce or minimize self-interference (particularly clutter echoes) via spatial isolation. Thus, the UE 402 and / or gNB 404 may determine uplink and downlink beams separated on respective antenna panels (and / or TRPs) to provide reliable full-duplex communication by selecting beam pairs that minimize or at least reduce self-interference at the UE 402 and / or gNB 404, respectively.

[0078] Measuring self-interference at a full-duplex capable wireless node can assist in determining uplink and downlink beam pairs that support full-duplex communication. For example, UE 402 (or an IAB child node, an MT unit, and / or another similar node) can obtain self-interference measurements to determine one or more candidate uplink transmission beams that can be paired with one or more candidate downlink reception beams. Additionally or alternatively, gNB 404 (or an IAB parent node, a CU, a DU, and / or another similar node) can obtain self-interference measurements to determine one or more candidate uplink reception beams that can be paired with one or more candidate downlink transmission beams. Typically, to obtain self-interference measurements, a full-duplex capable wireless node can transmit signals from a first group of antennas (and / or TRPs) in one or more transmission beam directions, and the wireless node can simultaneously measure received signals (e.g., reflected or leaked transmission signals) on a second group of antennas (and / or TRPs) in one or more reception beam directions, where the first group of antennas can be different from or the same as the second group of antennas.

[0079] In some cases, the UE may receive downlink transmissions (e.g., from a base station) using a transmission configuration such as a TCI state (e.g., represented by a TCI state data structure defined in a 3GPP specification and / or another standard). For example, a base station and a UE may be configured for beamformed communications, where the base station may transmit in the direction of the UE using a directional BS transmit beam, and the UE may receive transmissions using a directional UE receive beam. Each BS transmit beam may have an associated beam ID, beam direction, or beam symbol, among other things. In addition, a downlink beam (such as a BS transmit beam or a UE receive beam) may be associated with a TCI state. The TCI state may indicate a directionality or characteristic of a downlink beam, such as one or more quasi-co-location (QCL) attributes of a downlink beam. For example, as defined in a 3GPP specification and / or another standard, a qcl type indicator within a QCL information data structure may be used to indicate QCL attributes. QCL attributes may include, for example, Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, among other things. In some aspects, the TCI state can be further associated with an antenna port, an antenna panel, and / or a TRP. For different QCL types (e.g., QCL types for different combinations of Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, etc.), the TCI state can be associated with a downlink reference signal set (e.g., a synchronization signal block (SSB) and an aperiodic, periodic, or semi-persistent channel state information reference signal (CSI RS)). For example, as defined in a 3GPP specification and / or another standard, a referenceSignal indicator within a QCL information data structure can be used to indicate a downlink reference signal. In the case where the QCL type indicates a spatial reception parameter, the QCL type can correspond to an analog receive beamforming parameter of a UE receive beam at the UE.

[0080] A base station may configure a set of TCI states for use on a physical downlink shared channel (PDSCH), and a subset of those TCI states for use on a physical downlink control channel (PDCCH). The base station may use a radio resource configuration (RRC) message to provide the set of TCI states for the PDSCH and / or a subset of those TCI states for the PDCCH. For the PDSCH, the base station may transmit a medium access control (MAC) layer control element (MAC-CE) to activate a subset of TCI states for use on the PDSCH, and then schedule (e.g., using downlink control information (DCI)) a specific one of those activated TCI states for a PDSCH message. Similarly, for the PDCCH, the base station may transmit a MAC-CE to activate one TCI state in a subset of TCI states for a PDCCH message for use on the PDCCH.

[0081] For PDCCH, the base station typically activates one TCI state for each TRP at a time, and similarly for PDSCH. However, in some cases, the base station may transmit some messages in full-duplex symbols and other messages in half-duplex symbols. Therefore, the activated TCI state may be optimal for one full-duplex symbol or half-duplex symbol, and may be suboptimal for another full-duplex symbol or half-duplex symbol. For example, when the activated TCI state is the optimal state for a half-duplex symbol, the UE and / or the base station may experience increased self-interference. Therefore, when receiving the corresponding message, the UE will experience lower quality and / or reliability. In addition, when the quality and / or reliability are too low for the UE to receive and / or successfully decode these messages, the base station may consume additional network overhead and / or processing resources to retransmit those messages.

[0082] Some techniques and apparatus described herein enable activation of an optimal TCI state for messages from a base station (e.g., gNB 404) using full-duplex symbols and messages from gNB 404 using half-duplex symbols. In some aspects, the techniques and apparatus described herein provide multiple activated TCI states to a UE (e.g., UE 402) based at least in part on whether the message uses full-duplex symbols and / or half-duplex symbols. As a result, gNB 404 improves the reliability and / or quality of full-duplex communications at the UE. In addition, gNB 404 saves network overhead and processing resources by reducing the amount of retransmissions that may be required when reliability and / or quality are lower.

[0083] As indicated above, provide Figure 4D As an example. Other examples may be related to Figure 4D Different than described.

[0084] Figure 5A , Figure 5B and Figure 5C 500, 510, and 520 are diagrams showing examples of overlapping or adjacent symbols in full-duplex communication. Examples 500, 510, and 520 each include symbols depicted as regions within a time dimension and a frequency dimension. Figures 5A-5C In the example 500, 510 and 520, uplink communication and downlink communication use shaded symbols for their respective uplink and downlink channels. Examples 500, 510 and 520 each show an uplink symbol including DMRS for a physical uplink shared channel (PUSCH), and a downlink symbol including DMRS for a physical downlink shared channel (PDSCH). Although the following description will focus on PUSCH and PDSCH, the description is similarly applicable to other channels for uplink communication and / or other channels for downlink communication, respectively.

[0085] Examples 500, 510, and 520 may each be associated with a full-duplex mode of a UE (e.g., UE 402, UE 120, and / or another network node, such as an MT unit and / or a child IAB node) and / or a base station (e.g., gNB 404, base station 110, and / or another network node, such as a CU, DU, and / or a parent IAB node). Figure 5A As shown in , example 500 includes at least some downlink symbols and at least some uplink symbols overlapping in time and frequency. Thus, in example 500, UE 402 can transmit and receive simultaneously in the same frequency bandwidth. For example, UE 402 can transmit to gNB 404 and receive from gNB 404 simultaneously in one or more overlapping frequencies.

[0086] like Figure 5B As shown in , example 510 includes at least some uplink symbols being temporally adjacent to at least some downlink symbols. Figure 5B The example 510 shows no guard time between adjacent symbols, but the description similarly applies to configurations where at least some uplink symbols are separated in time from at least some downlink symbols by less than a threshold amount of time. Thus, in example 510, UE 402 may transmit a first set of symbols and receive a second set of symbols in the same frequency bandwidth, where the first set of symbols and the second set of symbols are separated in time with no guard time or with less than a threshold amount of time. For example, in one or more overlapping frequencies, UE 402 may transmit to gNB 404 during a first time period and receive from gNB 404 during a second time period.

[0087] like Figure 5C As shown in , example 520 includes at least some uplink symbols adjacent in frequency to at least some downlink symbols. Figure 5C The example 520 shows no guard bands between adjacent symbols, but the description similarly applies to configurations where at least some uplink symbols are separated in frequency from at least some downlink symbols by less than a threshold frequency amount. Thus, in example 520, UE 402 may transmit a first set of symbols in a first frequency bandwidth and simultaneously receive a second set of symbols in a second frequency bandwidth, where the first frequency bandwidth and the second frequency bandwidth are separated in frequency without a guard band or with a guard band less than a threshold frequency amount. For example, UE 402 may simultaneously transmit to gNB 404 in a first set of frequencies and receive from gNB 404 in a second set of frequencies.

[0088] As shown above, Figures 5A-5C are provided as examples. Other examples may be related to Figures 5A-5C Different than described.

[0089] Figure 6 6 is a diagram illustrating an example 600 of a transmission configuration for activating and using full-duplex mode according to the present disclosure. Figure 6 As shown in , example 600 includes a UE (e.g., UE 402, UE 120, and / or another network node, such as an MT unit and / or a child IAB node) communicating with a node (e.g., gNB 404, base station 110, and / or another network node, such as a CU, DU, and / or a parent IAB node). For example, the node may be in a wireless network (e.g., Figure 1 402 on a wireless network 100). Although the following description will focus on a node being a gNB 404, the description is also applicable to another network node communicating with the UE 402.

[0090] In example 600, UE 402 and / or gNB 404 may operate in full-duplex mode (e.g., as described above with respect to Figures 4A-4D As mentioned above about Figure 5A As described above, when in full-duplex mode, UE 402 can transmit and receive simultaneously in the same frequency bandwidth. Additionally or alternatively, as described above with respect to Figure 5B As described above, when in full-duplex mode, UE 402 may transmit a first set of symbols and receive a second set of symbols in the same frequency bandwidth, wherein the first set of symbols and the second set of symbols are separated in time by less than a time threshold. Additionally or alternatively, as described above with respect to Figure 5C As described, when in full-duplex mode, UE 402 may transmit a first set of symbols in a first frequency bandwidth and simultaneously receive a second set of symbols in a second frequency bandwidth, wherein the first frequency bandwidth and the second frequency bandwidth are separated in frequency by less than a frequency threshold.

[0091] As indicated with respect to reference numeral 605, the gNB 404 may transmit and the UE 402 may receive control information indicating at least two TCI states. In some aspects, a first TCI state of the at least two TCI states may be associated with a half-duplex mode of the UE 402, and a second TCI state of the at least two TCI states may be associated with a full-duplex mode of the UE 402.

[0092] In some aspects, the control information may include a MAC-CE and / or another control message. Additionally or alternatively, the message may include a DCI and / or another signal including information indicating at least two TCI states. In some aspects, the DCI may include a field indicating a first TCI state and / or a second TCI state. For example, the field may be a transmission configuration indication field as defined in a 3GPP specification and / or another standard.

[0093] In some aspects, the at least two TCI states may include a first plurality of TCI states and a second plurality of TCI states. The first plurality of TCI states may include a first TCI state and be associated with a half-duplex mode of the UE 402, and the second plurality of TCI states may include a second TCI state and be associated with a full-duplex mode of the UE 402. In some aspects, when the control information includes a DCI, as described above, the size of the field included in the DCI may be based at least in part on the number of the first plurality of TCI states and / or the number of the second plurality of TCI states. For example, the size of the field included in the DCI may be based at least in part on the larger of the number of the first plurality of TCI states and the number of the second plurality of TCI states.

[0094] Additionally or alternatively, the first TCI state and the second TCI state may be associated with a common resource set. For example, the common resource set may include a control resource set (CORESET). Thus, both the first TCI state and the second TCI state may be associated with the same CORESET.

[0095] In some aspects, the at least two TCI states may also include a third TCI state associated with a half-duplex mode of the UE 402 and a fourth TCI state associated with a full-duplex mode of the UE 402. For example, the message may indicate the third TCI state and the fourth TCI state in addition to the first TCI state and the second TCI state. In some aspects, the third TCI state and the fourth TCI state may be associated with a resource set that is different from a common resource set. For example, both the third TCI state and the fourth TCI state may be associated with a CORESET that is different from the first TCI state and the second TCI state.

[0096] Additionally or alternatively, the first TCI state and the second TCI state may be associated with a common TRP of a plurality of TRPs of the gNB 404. For example, both the first TCI state and the second TCI state may be associated with a common TRP. Thus, in some aspects, the third TCI state and the fourth TCI state (e.g., as described above) may be associated with different TRPs of a plurality of TRPs of the gNB 404. For example, both the third TCI state and the fourth TCI state may be associated with a TRP that is different from the first TCI state and the second TCI state.

[0097] As indicated with respect to reference numeral 610, the UE 402 may select a TCI state from the at least two TCI states indicated by the control information. For example, the UE 402 may select one of the at least two TCI states based at least in part on determining whether the intended downlink transmission is associated with a full-duplex mode of the UE 402 or associated with a half-duplex mode of the UE 402, and selecting a TCI state associated with the same mode.

[0098] As indicated with respect to reference numeral 615, in accordance with at least one of the first TCI state or the second TCI state, the gNB 404 may send a downlink transmission and the UE 402 may receive the downlink transmission. In some aspects, the gNB 404 may send a downlink transmission on a PDSCH, a PDCCH, and / or another downlink channel. Thus, the downlink transmission may include a PDSCH message, a PDCCH message, and / or another downlink message.

[0099] In some aspects, symbols associated with the full-duplex mode of UE 402 may overlap in time and / or frequency with one or more symbols used for uplink communications from UE 402, and symbols associated with the half-duplex mode of UE 402 may not overlap with one or more symbols used for uplink communications from UE 402. In some aspects, when a downlink transmission includes symbols associated with the half-duplex mode of UE 402, the downlink transmission may not include symbols associated with the full-duplex mode of UE 402. Similarly, when a downlink transmission includes symbols associated with the full-duplex mode of UE 402, the downlink transmission may not include symbols associated with the half-duplex mode of UE 402. Thus, in some aspects, gNB 404 may avoid combining symbols associated with the half-duplex mode of UE 402 and symbols associated with the full-duplex mode of UE 402 in the same downlink transmission.

[0100] Alternatively, the downlink transmission may include a first set of symbols associated with a half-duplex mode of the UE 402 and a second set of symbols associated with a full-duplex mode of the UE 402. As described above, the first set of symbols may overlap in time and / or frequency with one or more symbols used for uplink communications from the UE 402, and the second set of symbols may not overlap with one or more symbols used for uplink communications from the UE 402. In some aspects, the gNB 404 may send a downlink transmission according to the first TCI state or the second TCI state, but not according to a combination of the first TCI state and the second TCI state, and the UE 402 may receive the downlink transmission. For example, when the downlink communication includes a combination of half-duplex symbols and full-duplex symbols, the UE 402 may apply one or more rules (e.g., preconfigured and / or based at least in part on control information) to select a TCI state associated with the full-duplex mode of the UE 402 (such as the second TCI state) or a TCI state associated with the half-duplex mode of the UE 402 (such as the first TCI state). Alternatively, based on a combination of the first TCI state and the second TCI state, the gNB 404 may send a downlink transmission and the UE 402 may receive the downlink transmission.

[0101] Through such as Figure 6 By sending downlink transmissions as described, gNB 404 can improve the quality and / or reliability of the transmissions. In addition, due to the improved quality and / or reliability, gNB 404 can reduce the possible need to resend downlink transmissions, which saves network and processing resources at gNB 404 and UE 402.

[0102] As indicated above, provide Figure 6 As an example. Other examples may be related to Figure 6 Different than described.

[0103] Figure 7 7 is a diagram illustrating an exemplary process 700 performed, for example, by a UE in accordance with the present disclosure.

[0104] like Figure 7 As shown in , in some aspects, process 700 may include receiving control information indicating at least two TCI states from a base station (e.g., gNB 404 and / or base station 110) (box 710). For example, a UE (e.g., using one or more of antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, controller / processor 280, and / or memory 282) may receive control information indicating at least two TCI states from a base station, as described above.

Exemplary process 800 is an example of a base station (e.g., gNB 404 and / or base station 110) performing operations associated with activating and using a transmission configuration for full-duplex mode.

[0128] like Figure 8 As shown in , in some aspects, process 800 may include transmitting control information indicating at least two TCI states to a UE (e.g., UE 402 and / or UE 120) (block 810). For example, a base station (e.g., using one or more of transmit processor 220, TX MIMO processor 230, modulator 232, antenna 234, controller / processor 240, memory 242, and / or scheduler 246) may transmit control information indicating at least two TCI states to a UE, as described above.
