Technical Field

[0003] This disclosure generally relates to wireless communications and techniques and apparatus for rate matching, puncturing, and power scaling of uplink communications in full-duplex mode. Background Technology

[0004] Wireless communication systems are widely used to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. 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, and / or similar). 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 issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that can support communication by multiple user equipment (UEs). UEs can communicate with the BS via downlinks and uplinks. A "downlink" (or forward link) refers to the communication link from the BS to the UE, and an "uplink" (or reverse link) refers to the communication link from the UE to the 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, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, and / or similar.

[0006] The multiple access technologies described above have been adopted in various telecommunications standards to provide a universal protocol that enables different user equipment to communicate at the municipal, national, regional, and even global levels. New Radio (NR) (also known as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR aims to better support mobile broadband internet access by: improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0038] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or a method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods that are practiced using other structures, functions, or structures and functions other than or attached to the various aspects of this disclosure described herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0039] Several aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed embodiments and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, and / or similar elements (collectively, “elements”). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0040] It should be noted that while the terms commonly associated with 5G or NR Radio Access Technologies (RATs) may be used to describe aspects herein, aspects of this disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).

[0041] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to various aspects of this disclosure. Among other examples, the wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include multiple 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, Transmit / Receive Point (TRP), or similar. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0042] A Base Station (BS) can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and allow restricted access for UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macrocell can be referred to as a macro BS. A BS for a picocell can be referred to as a pico BS. A BS for a femtocell can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A base station can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR-BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0043] In some respects, the cell is not necessarily stationary, and the geographical area of ​​the cell can move depending on the location of the mobile BS. In some respects, the BS can interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transmitting network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0044] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station may also be referred to as a relay station, relay base station, relay, or similar.

[0045] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs), such as macro BSs, pico BSs, femto BSs, relay BSs, or similar. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0046] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other, for example, directly or indirectly via wireless or wired backhaul.

[0047] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, or similar. A UE may be a cellular phone (e.g., a smartphone), 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 biometric sensor / device, a wearable device (smartwatch, 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 component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0048] Some UEs can be considered 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, instruments, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to or to a network (e.g., a wide area network, such as the Internet or a cellular network) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0049] Typically, any number of wireless networks can be deployed within a given geographic area. Each wireless network can support a specific Radio Access Platform (RAT) and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, or similar. A frequency can also be referred to as a carrier, frequency channel, or similar. Each frequency can support a single RAT within a given geographic area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0050] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidechain channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0051] Devices of the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, or similar based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating band with a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band with a second frequency range (FR2), which can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are generally referred to as intermediate frequencies (IFs). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the “sub-6 GHz” band. Similarly, FR2 is often referred to as the “millimeter wave” band, although this differs from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU). Therefore, unless otherwise specified, it should be understood that the term "sub-6 GHz" or similar, if used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specified, it should be understood that the term "millimeter wave" or similar, if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency frequencies (e.g., less than 24.25 GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to these modified frequency ranges.

[0052] As shown above, it provides Figure 1 As an example. Other examples may differ from those regarding... Figure 1 Example of the description.

[0053] Figure 2This 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 to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T ≥ 1 and R ≥ 1.

[0054] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process (e.g., code and modulate) the data for each UE based at least in part on the selected MCS(s) for the UE, and provide data symbols for all UEs. Transmitting 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. Transmitting 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 signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can 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 to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0055] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain the received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide data for decoding for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Signal Received Power (RSRP) parameter, the Received Signal Strength Indicator (RSSI) parameter, the Reference Signal Received Quality (RSRQ) parameter, and / or the Channel Quality Indicator (CQI) parameter, among other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0056] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0057] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements.

[0058] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-encoded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modem of UE 120 may include a modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266.

[0059] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, the modem of base station 110 may include modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110. In some aspects, base station 110 includes transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TXMIMO 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., references). Figures 5A-11 ).

[0060] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2Any other component(s) may perform one or more techniques associated with controlling the power of uplink communication in full-duplex mode, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component(s) can execute or bootstrap, for example Figure 8 The process 800 Figure 9 The process 900 Figure 10 Process 1000 Figure 11 The operation of process 1100 and / or other processes described herein. Memory 242 and 282 may store data and program code of 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, when executed by one or more processors of base station 110 and / or UE 120 (e.g., direct execution, or execution after compilation, transformation, and / or interpretation), the one or more instructions may cause one or more processors, UE 120, and / or base station 110 to execute or guide, for example...

In some aspects, execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, among other examples.

[0061] In some aspects, the UE (e.g., UE 120) may include components for adjusting transmission parameters associated with uplink transmissions from the UE such that the phase of the uplink transmission is continuous over the symbols of the uplink transmission, wherein adjusting the transmission parameters includes at least one of: rate matching, puncturing, or power scaling of one or more symbols in the uplink transmission, modifying at least one of the MCS or power associated with downlink transmissions to the UE, or a combination thereof; and / or components for transmitting uplink transmissions to base station components at least in part based on the adjusted transmission parameters.

[0063] In some aspects, the UE (e.g., UE 120) may include components for receiving scheduling information associated with uplink transmissions from the UE from a base station, wherein the scheduling information indicates that the uplink transmission is mapped to a first symbol group that overlaps at least partially with downlink communication from the base station, and wherein the scheduling information further indicates that the uplink transmission is excluded from a second symbol group that overlaps at least partially with a reference signal from the base station; and / or components for transmitting uplink transmissions to base station components based at least partially on the scheduling information.

[0064] In some aspects, a base station (e.g., base station 110) may include components for transmitting to a UE scheduling information associated with uplink transmissions from the UE, wherein the scheduling information indicates that the uplink transmission is mapped to a first symbol group that at least partially overlaps with downlink communication from the base station, and wherein the scheduling information further indicates that the uplink transmission is excluded from a second symbol group that at least partially overlaps with a reference signal from the base station; and / or components for receiving uplink transmissions from the UE components based at least partially on the scheduling information. Components for the base station to perform the operations described herein may include one or more of, for example, a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0065] Although Figure 2 The boxes in the diagram are shown as different components, but the descriptions of the functions of the boxes above can be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0066] As shown above, it provides Figure 2 As an example. Other examples may differ from those regarding... Figure 2 Example of the description.

[0067] Figure 3 This is a diagram illustrating an example beamforming architecture 300 supporting mmW communication according to the present disclosure. In some aspects, architecture 300 may implement aspects of wireless network 100. In some aspects, architecture 300 may 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.

[0068] In summary, Figure 3 This is a diagram illustrating example hardware components of a wireless communication device according to certain aspects of this disclosure. The components shown may include components that can be used for antenna element selection and / or for beamforming for wireless signal transmission. Many architectures exist for antenna element selection and phase shifting; only one example is shown here. 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 splitter 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.

[0069] Transmit lines or other waveguides, wires, and / or traces are shown to connect the various components to illustrate how the signal to be transmitted is transmitted between the components. Reference numerals 322, 324, 326, and 328 indicate areas in architecture 300 where different types of signals travel or are processed. Specifically, reference numeral 322 indicates the area where digital baseband signals travel or are processed, reference numeral 324 indicates the area where analog baseband signals travel or are processed, reference numeral 326 indicates the area where analog intermediate frequency (IF) signals travel or are processed, and reference numeral 328 indicates the area where analog radio frequency (RF) signals travel or are processed. The architecture also includes a local oscillator A330, a local oscillator B332, and a controller / processor 334. In some aspects, the controller / processor 334 corresponds to the combination described above. Figure 2The described base station controller / processor 240 and / or the combination thereof Figure 2 The UE controller / controller 280 described in the document.

[0070] Each antenna element 320 may include one or more sub-elements for transmitting or receiving RF signals. For example, a single antenna element 320 may include a first sub-element cross-polarized with a second sub-element, which can be used to independently transmit the cross-polarized signal. Antenna elements 320 may include patch antennas, dipole antennas, or other types of antennas arranged in a linear, two-dimensional, or other configuration. Antenna elements 320 may be spaced apart in a manner that allows signals transmitted individually by antenna elements 320 at desired wavelengths to interact or interfere with each other (e.g., to shape a desired beam). For example, given a desired wavelength or frequency range, this spacing may provide a quarter-wavelength, half-wavelength, or other fraction of a wavelength spacing between adjacent antenna elements 320 to allow interaction or interference of signals transmitted by individual antenna elements 320 within that desired range.

[0071] Modem 302 processes and generates digital baseband signals and can also control the operation of DAC 304, first mixer 306 and second mixer 308, splitter 310, first amplifier 312, phase shifter 314 and / or second amplifier 316 to transmit signals via one or more antenna elements 320. Modem 302 can process signals and control operations according to communication standards such as the wireless standards discussed herein. DAC 304 can convert digital baseband signals received from (and to be transmitted) by modem 302 into analog baseband signals. First mixer 306 uses local oscillator A 330 to up-convert the analog baseband signal to an analog IF signal within the IF. For example, first mixer 306 can mix the signal with an oscillation signal generated by local oscillator A 330 to "shift" the baseband analog signal to the IF. In some cases, some processing or filtering (not shown) may be performed at the IF. Second mixer 308 uses local oscillator B 332 to up-convert the analog IF signal to an analog RF signal. Similar to the first mixer, the second mixer 308 can mix the signal with the oscillation signal generated by the local oscillator B 332 to "shift" the IF analog signal to the RF or frequency at which the signal will be transmitted or received. The modem 302 and / or the controller / processor 334 can adjust the frequencies of the local oscillator A 330 and / or the local oscillator B 332 to produce the desired IF and / or RF frequencies, and to facilitate the processing and transmission of the signal within the desired bandwidth.

[0072] In the illustrated architecture 300, the signal up-converted by the second mixer 308 is split or replicated into multiple signals by the splitter 310. The splitter 310 in architecture 300 splits the RF signal into multiple identical or nearly identical RF signals. In other examples, any type of signal can be used for splitting, including baseband digital, baseband analog, or IF analog signals. Each of these signals may correspond to an antenna element 320, and the signal travels through and is processed by amplifiers 312 and 316, phase shifter 314, and / or other elements corresponding to and processed by the respective antenna element 320, to be provided to and transmitted by the corresponding antenna element 320 of the antenna array 318. In one example, the splitter 310 may be an active splitter connected to a power supply, providing some gain such that the RF signal leaving the splitter 310 is at a power level equal to or greater than the signal entering the splitter 310. In another example, splitter 310 is a passive splitter that is not connected to a power source, and the power level of the RF signal leaving splitter 310 may be lower than that of the RF signal entering splitter 310.

[0073] After being split by splitter 310, the resulting RF signal can enter an amplifier, such as first amplifier 312 or phase shifter 314 corresponding to antenna element 320. First and second amplifiers 312 and 316 are shown in dashed lines because in some aspects, one or both may not be necessary. In some aspects, both first amplifier 312 and second amplifier 316 are present. In some aspects, neither first amplifier 312 nor second amplifier 316 is present. In some aspects, one of the two amplifiers 312 and 316 is present, while the other is absent. For example, if splitter 310 is an active splitter, first amplifier 312 may not be used. As a further example, if phase shifter 314 is an active phase shifter that can provide gain, second amplifier 316 may not be used.

[0074] Amplifiers 312 and 316 can provide desired levels of positive or negative gain. Positive gain (positive dB) can be used to increase the signal amplitude radiated by a particular antenna element 320. Negative gain (negative dB) can be used to reduce the amplitude and / or suppress the signal radiation of 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 control over the gain of each antenna element 320. For example, modem 302 and / or controller / processor 334 may have at least one control line connected to each of splitter 310, first amplifier 312, phase shifter 314, and / or second amplifier 316, which can be used to configure the gain to provide the desired amount of gain for each component and therefore each antenna element 320.

[0075] Phase shifter 314 can provide a configurable phase shift or phase offset to the corresponding RF signal to be transmitted. Phase shifter 314 can be a passive phase shifter that is not directly connected to a power supply. Passive phase shifters may introduce some insertion loss. Second amplifier 316 can boost the signal to compensate for the insertion loss. Phase shifter 314 can also be an active phase shifter connected to a power supply, such that an active phase shifter provides a certain amount of gain or prevents insertion loss. The settings of each phase shifter 314 are independent, meaning that each phase shifter can be independently configured to provide the desired amount of phase shift, the same amount of phase shift, or some other configuration. Modem 302 and / or controller / processor 334 may have at least one control line connected to each phase shifter 314, and this control line can be used to configure the phase shifters 314 to provide the desired amount of phase shift or phase offset between antenna elements 320.

[0076] In the illustrated architecture 300, the RF signal received by antenna element 320 is provided to one or more first amplifiers 356 to enhance signal strength. The first amplifiers 356 may be connected to the same antenna array 318 (e.g., for time division duplex (TDD) operation). The first amplifiers 356 may be connected to different antenna arrays 318. The boosted RF signal is input to one or more phase shifters 354 to provide a configurable phase shift or phase offset to the corresponding received RF signal to achieve reception via one or more Rx beams. The phase shifters 354 may be active or passive phase shifters. The phase shifters 354 are configured independently, meaning that each phase shifter can be independently configured to provide a desired amount of phase shift, the same amount of phase shift, or some other configuration. The modem 302 and / or controller / processor 334 may have at least one control line connected to each phase shifter 354, and this control line can be used to configure the phase shifters 354 to provide a desired amount of phase shift or phase offset between antenna elements 320 to achieve reception via one or more Rx beams.

[0077] 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 amplifiers 352 can be individually configured to provide a configured amount of gain. Second amplifiers 352 can be individually configured to provide a certain amount of gain to ensure that the signals input to combiner 350 have the same amplitude. Amplifiers 352 and / or 356 are shown in dashed lines because they may not be necessary in some aspects. In some aspects, both amplifiers 352 and 356 are present. In another aspect, neither amplifier 352 nor amplifier 356 is present. In other aspects, one of amplifiers 352 and 356 is present, while the other is not.

[0078] In the illustrated architecture 300, the signals output from phase shifter 354 (via amplifier 352 when present) are combined in combiner 350. Combiner 350 in architecture 300 combines RF signals into a single signal. Combiner 350 can be a passive combiner (e.g., not connected to a power supply), which may result in some insertion loss. Combiner 350 can also be an active combiner (e.g., connected to a power supply), which may result in some signal gain. When combiner 350 is an active combiner, it can provide different (e.g., configurable) amounts of gain for each input signal, such that the input signals have the same amplitude when combined. When combiner 350 is an active combiner, combiner 350 may not require a second amplifier 352, as the active combiner can provide signal amplification.

[0079] The output of combiner 350 is input to mixers 348 and 346. Mixers 348 and 346 typically down-convert the received RF signal using inputs from local oscillators 372 and 370, respectively, to generate intermediate or baseband signals carrying coded and modulated information. The outputs of mixers 348 and 346 are input to analog-to-digital converter (ADC) 344 for conversion into analog signals. The analog signal output from ADC 344 is input to modem 302 for baseband processing, such as decoding, deinterleaving, or similar operations.

[0080] Architecture 300 is given by way of example only to illustrate an architecture for transmitting and / or receiving signals. In some cases, architecture 300 and / or each part of architecture 300 may be repeated multiple times within the architecture to accommodate or provide any number of RF chains, antenna elements, and / or antenna panels. Furthermore, many alternative architectures are possible and contemplated. For example, although only a single antenna array 318 is shown, two, three, or more antenna arrays may be included, each having its own corresponding amplifier, phase shifter, splitter, mixer, DAC, ADC, and / or modem, one or more of these. 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.

[0081] Furthermore, mixers, splitters, amplifiers, phase shifters, and other components can be located in different signal type regions within different implementation architectures (e.g., indicated by different reference numerals in reference numerals 322, 324, 326, and 328). For example, in different examples, the signal to be transmitted can be split 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 splitters 310, amplifiers 312 and 316, or phase shifters 314 can be located between DAC 304 and the first mixer 306, or between the first mixer 306 and the second mixer 308. In one example, the functionality of one or more components can be combined into a single component. For example, phase shifter 314 can perform amplification to include or replace the first amplifier 312 and / or the second amplifier 316. As a further example, phase shifting can be implemented by the second mixer 308 to eliminate the need for a 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-RF mixers within the second mixer 308 (e.g., for each antenna element chain), and the local oscillator B332 may provide a different local oscillator signal (with different phase shifts) to each IF-RF mixer.

[0082] Modem 302 and / or controller / processor 334 can control one or more of other components 304 to 372 to select one or more antenna elements 320 and / or shape a beam for transmitting one or more signals. For example, antenna element 320 can be individually selected or deselected for signal (or multiple signals) transmission by controlling the amplitude of one or more corresponding amplifiers (such as first amplifier 312 and / or second amplifier 316). Beamforming involves 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 shaped beam can carry physical or higher-level reference signals or information. As each of the multiple signals is radiated from the corresponding antenna element 320, the radiated signals interact, interfere (constructive and destructive interference), and amplify each other to shape the resulting beam. Shape (such as amplitude, width, and / or the presence of sidelobes) and orientation (such as the angle of the beam relative to the surface of antenna array 318) can be dynamically controlled by modifying the phase shift or phase offset of multiple signals relative to each other, imparted by phase shifter 314, and the amplitude imparted by amplifiers 312 and 316. The controller / processor 334 may be partially or wholly located within one or more other components of architecture 300. For example, in some aspects, the controller / processor 334 may be located within modem 302.

[0083] As shown above, it provides Figure 3 As an example. Other examples may differ from those regarding... Figure 3 Example of the description.

[0084] Figure 4A , 4B Figures 400, 410, and 420 are examples illustrating full-duplex communication, respectively. (See diagram 4C.) Figures 4A-4C As shown, each of Examples 400, 410, and 420 includes 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 are provided as examples only, and the wireless network can support full-duplex communication between other devices (e.g., between mobile terminal (MT) nodes and control nodes (e.g., central unit (CU) or distributed unit (DU)), between child nodes and parent nodes in an integrated access backhaul (IAB) network, and / or between scheduled nodes and scheduling nodes).

[0085] like Figure 4A As shown, Example 400 includes a UE 402 communicating with two base stations (or TRPs) 404-1 and 404-2. Figure 4A As shown, UE 402 can send one or more uplink transmissions to base station 404-1, and can simultaneously receive one or more downlink transmissions from base station 404-2. Therefore, in Figure 4A In Example 400 shown, full-duplex communication is enabled for UE 402, which can operate as a full-duplex node, but full-duplex communication is not enabled for base stations 404-1 and 404-2, which can operate as half-duplex nodes. Additionally or alternatively, as... Figure 4B As shown, Example 410 includes two UEs (UE1 402-1 and UE2 402-2) communicating with a base station (or TRP) 404. In this case, base station 404 can send one or more downlink transmissions to UE1 402-1 and can simultaneously receive one or more uplink transmissions from UE2 402-2. Therefore, in Figure 4B In Example 410 shown, full-duplex communication is enabled for base station 404, which can operate as a full-duplex node, but full-duplex communication is not enabled for UE1 402-1 and UE2 402-2, which can operate as half-duplex nodes. Additionally or alternatively, as... Figure 4C As shown, Example 420 includes a UE 402 communicating with a base station (or TRP) 404. In this case, base station 404 can transmit and UE 402 can receive one or more downlink transmissions, while UE 402 transmits and base station 404 receives one or more uplink transmissions. Therefore, in Figure 4CIn Example 420 shown, full-duplex communication is enabled for both UE 402 and base station 404, where each of them operates as a full-duplex node.

[0086] Full-duplex communication reduces latency by allowing full-duplex nodes to transmit or receive downlink signals in uplink-only time slots and / or transmit and receive uplink signals in downlink-only time slots. Furthermore, full-duplex communication enhances spectral efficiency and / or network throughput (e.g., on a per-cell and / or per-UE basis), resulting in more efficient resource utilization by simultaneously utilizing the time and frequency resources of both uplink and downlink communication.

[0087] As mentioned above, providing Figures 4A-4C As an example. Other examples may differ from those regarding... Figures 4A-4C Example of the description.

[0088] Figure 4D This is a diagram illustrating another example 430 of full-duplex communication. (See diagram 430) Figure 4D As shown, Example 430 includes a wireless network that supports full-duplex communication (e.g., Figure 1 UE 402 communicates 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 are provided as examples only, and the wireless network can support full-duplex communication between other devices (e.g., between MT nodes and control nodes, between child nodes and parent nodes in an IAB network, and / or between scheduled nodes and scheduling nodes).

[0089] like Figure 4D As shown, UE 402 may experience self-interference (SI) between uplink communication to gNB 404 and downlink communication from gNB 404. Similarly, gNB 404 may experience SI between uplink communication from UE 402 and downlink communication to UE 402. In some aspects, SI can be caused by time and / or frequency overlap between uplink and downlink communication (e.g., as combined below). Figure 5A Additionally or alternatively, SI can be caused by little or no guard time and / or frequency between uplink and downlink communications (e.g., as combined below). Figures 5B-5C The above).

[0090] Therefore, full-duplex communication can 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 different antenna panels and / or TRPs of the base station) to reduce or minimize self-interference (especially clutter echoes) via spatial isolation. Thus, UE 402 and / or gNB 404 can determine separate uplink and downlink beams on their 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 UE 402 and / or gNB 404, respectively.

[0091] Measuring self-interference at a full-duplex-capable radio node can help determine uplink and downlink beam pairs that support full-duplex communication. For example, UE 402 (or an IAB subnode, MT unit, and / or another similar node) can obtain self-interference measurements to determine one or more candidate uplink transmit beams that can be paired with one or more candidate downlink receive beams. Additionally or alternatively, gNB 404 (or an IAB parent node, CU, DU, and / or another similar node) can obtain self-interference measurements to determine one or more candidate uplink receive beams that can be paired with one or more candidate downlink transmit beams. Typically, to obtain self-interference measurements, a full-duplex-capable radio node can transmit signals from a first antenna group (and / or TRP) in one or more transmit beam directions, and the radio node can simultaneously measure the received signal (e.g., reflected or leaked transmit signal) on a second antenna group (and / or TRP) in one or more receive beam directions, where the first antenna group may be different from or the same as the second antenna group.

[0092] In some cases, the UE can rate-match one or more symbols transmitted to the base station in the uplink (e.g., corresponding to one or more symbols transmitted in the downlink). Therefore, the UE can estimate self-interference between the uplink and downlink transmissions. Additionally or alternatively, the UE can puncture one or more symbols transmitted in the uplink, such that at least a portion of the punctured symbols are not transmitted, and thus do not interfere with the temporal and / or frequency overlap of the downlink transmitted symbols. For example, the UE can measure non-self-interference based on the downlink transmitted symbols corresponding to the punctured symbols in the uplink transmission. Additionally or alternatively, the UE can receive DMRS within the downlink transmitted symbols corresponding to the punctured symbols in the uplink transmission. However, when only some symbols in the uplink transmission are rate-matched and / or punctured, the UE may cause phase discontinuities in the uplink transmission. Phase discontinuities lead to a reduction in the reliability and / or quality of the uplink transmission at the base station. Furthermore, when the base station is unable to decode the uplink transmission due to phase discontinuity, the UE may have to retransmit the uplink transmission, which wastes the processing resources and power of the UE and the base station, as well as network overhead.

[0093] Some aspects described herein relate to techniques and apparatuses capable of reducing or even eliminating phase discontinuities in uplink communication from a UE (e.g., UE 402 and / or UE 120) to a base station (e.g., gNB 404 and / or base station 110). In some aspects, the techniques and apparatuses described herein enable UE 402 to adjust the transmission power of different symbols in uplink communication to reduce or even eliminate phase discontinuities. Additionally or alternatively, the techniques and apparatuses described herein enable UE 402 to maintain continuous phase between gaps in symbols of uplink communication to reduce or even eliminate phase discontinuities. Therefore, UE 402 can improve the reliability and / or quality of full-duplex communication. Furthermore, UE 402 can save network overhead and processing resources by reducing the number of uplink communication retransmissions that may be required due to phase discontinuities. Alternatively, the techniques and apparatuses described herein enable gNB 404 to schedule uplink communication, excluding symbols that at least partially overlap with reference signals from gNB 404. Therefore, the gNB 404 can improve the reliability and / or quality of full-duplex communication. Furthermore, the gNB 404 can save network overhead and processing resources by reducing the number of uplink communication retransmissions that may be necessary due to phase discontinuities.

[0094] As shown above, it provides Figure 4D As an example. Other examples may differ from those regarding... Figure 6D Example of the description.

[0095] Figure 5A ,5B Figures 500, 510, and 520 are examples of overlapping or adjacent symbols in full-duplex communication, respectively. Examples 500, 510, and 520 each include symbols depicted as regions within the time and frequency dimensions. Figures 5A-5C In this context, uplink and downlink communications use shaded symbols for the corresponding uplink and downlink channels. Examples 500, 510, and 520 each illustrate uplink symbols including DMRS for the Physical Uplink Shared Channel (PUSCH) and downlink symbols including DMCRS for the Physical Downlink Shared Channel (PDSCH). Although the following description will focus on PUSCH and PDSCH, this description similarly applies to other channels used for uplink communications and / or other channels used for downlink communications, respectively.

[0096] Each of Examples 500, 510, and 520 can 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 sub-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, Example 500 includes at least some downlink symbols and at least some uplink symbols that overlap in time and frequency. Therefore, in Example 500, UE 402 can simultaneously transmit and receive in the same frequency bandwidth. For example, UE 402 can simultaneously transmit to and receive from gNB 404 in one or more overlapping frequencies.

[0097] like Figure 5B As shown, Example 510 includes at least some uplink symbols that are temporally adjacent to at least some downlink symbols. Although Figure 5B The example illustrates a configuration where there is no guard time between adjacent symbols; however, this description similarly applies to configurations where at least some uplink symbols are temporally separated from at least some downlink symbols by a threshold time amount. Therefore, in Example 510, UE 402 can transmit a first symbol group and receive a second symbol group in the same frequency bandwidth, where the first and second symbol groups are temporally separated and there is no guard time or the guard time is less than a threshold time amount. For example, UE 402 can transmit to gNB 404 at one or more overlapping frequencies during a first time period and receive from gNB 404 during a second time period.

[0098] like Figure 5C As shown, Example 520 includes at least some uplink symbols that are frequency-adjacent to at least some downlink symbols. Although Figure 5CThe example illustrates a configuration where there is no guard band between adjacent symbols; however, this description similarly applies to configurations where at least some uplink symbols are separated from at least some downlink symbols by a frequency amount less than a threshold. Therefore, in Example 520, UE 402 can transmit a first group of symbols in a first frequency bandwidth and simultaneously receive a second group of symbols in a second frequency bandwidth, wherein the first and second frequency bands are separated at frequencies where there is no guard band or the guard band is less than a threshold frequency amount. For example, UE 402 can simultaneously transmit to gNB 404 in the first frequency group and receive from gNB 404 in the second frequency group.

[0099] As mentioned above, providing Figures 5A-5C As an example. Other examples may differ from those regarding... Figures 5A-5C Example of the description.

[0100] Figure 6A , 6B Figures 600, 610, 620, and 630 are examples of uplink transmit power, respectively. In each of examples 600, 610, and 620, the transmit power is constant across symbols. In example 630, the phase is continuous between symbols, even though some symbols are interleaved. Examples 600, 610, 620, and 630 each include symbols with rate matching and / or puncturing, as well as symbols lacking rate matching and puncturing. Examples 600, 610, 620, and 630 each illustrate uplink symbols for a PUSCH. Although the following description will focus on the PUSCH, this description is equally applicable to other channels of uplink communication.

[0101] Examples 600, 610, 620, and 630 can 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 sub-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 6AAs shown, Example 600 includes two symbols in an uplink transmission that are rate-matched and / or punctured, and three symbols in an uplink transmission that are not rate-matched and punctured. For example, the two symbols may correspond to symbols in a downlink transmission (such as a PDSCH message and / or another downlink message) that include DMRS, which at least partially overlaps with the uplink transmission in time and / or frequency. Thus, in Example 600, while the transmit power of each resource element (RE) in the uplink transmission is constant across all symbols of the uplink transmission, the uplink transmission may have a varying transmit power depending on which symbol the UE 402 transmits in. As used herein, "resource element" or "RE" may refer to a portion of a resource element group (REG) that includes multiple REs (such as four consecutive REs) and each RE includes one symbol and one subcarrier. "Subcarrier" may refer to a frequency at least partially based on the "carrier" frequency, and subcarriers may be aggregated to transmit information wirelessly (e.g., using OFDM symbols and / or other RF symbols). Figure 6A As further shown, UE 402 can perform rate matching, puncturing, and / or power scaling on the other three symbols so that the transmit power of the uplink transmission is constant across the uplink transmitted symbols.

[0102] like Figure 6B As shown, Example 610 similarly includes two symbols in uplink transmission with rate matching and / or puncturing, and three symbols in uplink transmission without rate matching and puncturing. Therefore, in Example 610, while the transmit power of each RE in the uplink transmission is constant across all symbols in the uplink transmission, the uplink transmission can have varying transmit power depending on which symbol the UE 402 transmits in. Figure 6B As further illustrated, UE 402 can suppress rate matching and / or puncturing of the two symbols, such that the transmit power of the uplink transmission is constant for the uplink transmitted symbols. In Example 610, UE 402 can modify at least one of the MCS, the power associated with the downlink transmission to UE 402, and / or another transmission parameter to compensate for the suppression of rate matching and / or puncturing of the two symbols.

[0103] like Figure 6C As shown, Example 620 similarly includes two symbols with rate matching and / or puncturing in uplink transmission, and three symbols without rate matching and puncturing in uplink transmission. Therefore, in Example 620, while the transmit power of each RE in uplink transmission is constant across all symbols in the uplink transmission, the uplink transmission can have varying transmit power depending on which symbol the UE 402 transmits in. Figure 6CAs further illustrated, UE 402 can perform power scaling on two symbols to increase the transmission power of each resource element of the two symbols, and can also perform rate matching, puncturing and / or power scaling on the other three symbols to reduce the transmission power of the other three symbols, so that the transmission power of the uplink transmission is constant on the uplink transmission symbols.

[0104] like Figure 6D As shown, Example 630 similarly includes two symbols with rate matching and / or puncturing scheduled by gNB 404 in uplink transmission, and three symbols without rate matching and puncturing scheduled by gNB 404 in uplink transmission. In Example 630, UE 402 does not transmit in the two symbols with rate matching (e.g., by not mapping the uplink transmission to the two symbols), causing the two symbols to form a gap in the uplink transmission. Therefore, in Example 630, while the transmit power of each RE in the uplink transmission is constant over the entire symbol of the uplink transmission, the uplink transmission can have a varying transmit power depending on which symbol UE 402 transmits in. Therefore, UE 402 can modulate the padding symbols within the two symbols, even if no signal is transmitted during the two symbols, such that the phase of the uplink transmission is continuous between the symbols of the uplink transmission.

[0105] By ensuring that the transmit power of the uplink transmission is constant across the symbols transmitted in the uplink, UE 402 can avoid phase discontinuities in uplink transmission. Additionally or alternatively, UE 402 can use padding symbols to avoid phase discontinuities in uplink transmission, even when some symbols transmitted in the uplink are gaps. As described above, UE 402 can improve the reliability and / or quality of uplink transmission by avoiding phase discontinuities.

[0106] As mentioned above, providing Figures 6A-6D As one or more examples. Other examples may differ from those regarding... Figures 6A-6D Example of the description.

[0107] Figure 7 This is a diagram illustrating example 700 of rate matching, puncturing, and power scaling of uplink communication in full-duplex mode according to this disclosure. Figure 7 As shown, Example 700 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 (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 can be in a wireless network (e.g., Figure 1The network node communicates with UE 402 on the wireless network 100. Although the following description will focus on the node as gNB 404, the description also applies to another network node communicating with UE 402.

[0108] In Example 700, UE 402 and / or gNB 404 can operate in full-duplex mode (e.g., as combined above). Figures 4A-4D As stated above). Figure 5A As stated above, when in full-duplex mode, UE 402 can simultaneously transmit and receive within the same frequency bandwidth. Additionally or alternatively, as described above... Figure 5B As described above, when in full-duplex mode, UE402 can transmit a first symbol group and receive a second symbol group in the same frequency bandwidth, wherein the first symbol group and the second symbol group are separated in time by a time threshold less than a certain threshold. Additionally or alternatively, as described above... Figure 5C As stated, when in full-duplex mode, UE 402 can transmit a first symbol group in a first frequency bandwidth and simultaneously receive a second symbol group in a second frequency bandwidth, wherein the first frequency bandwidth and the second frequency bandwidth are separated in frequency by a frequency threshold less than a certain threshold.

[0109] As shown in conjunction with reference numeral 705, gNB 404 can transmit and UE 402 can receive a message that triggers UE 402 to adjust transmission parameters associated with uplink transmissions from UE 402. As used herein, the message can be “triggered” by causing UE 402 to perform an action (e.g., adjust transmission parameters) in response to receiving the message and / or in response to information included and / or indicated in the message. Additionally or alternatively, the message can be “triggered” by providing UE 402 with one or more parameters and / or other information for UE 402 to perform an action (e.g., adjust transmission parameters).

[0110] In some aspects, the message may include a Media Access Control (MAC) control element (MAC-CE) and / or another control element. Additionally or alternatively, the message may include downlink control information (DCI) and / or another signal including information associated with uplink transmission. In some aspects, UE 402 may adjust transmission parameters associated with uplink transmission based, at least in part, on the message, either directly or otherwise.

[0111] In some aspects, the message may include configuration for rate matching and / or puncturing at least one symbol in uplink transmission. For example, gNB 404 may send the message to trigger UE 402 to rate match one or more symbols in uplink transmission and / or puncture one or more symbols in uplink transmission (e.g., to allow gNB 404 to transmit downlink DMRS without self-interference, as described above).

[0112] In some aspects, uplink transmissions may be associated with a channel including at least one of the following: PUSCH, Physical Uplink Control Channel (PUCCH), Random Access Channel (RACH), or combinations thereof. Additionally or alternatively, uplink transmissions may be associated with resource indicators. For example, uplink transmissions may be associated with Sounding Reference Signal (SRS) resources.

[0113] Additionally or alternatively, the first uplink transmission may be associated with the Ultra Reliable Low Latency Communication (URLLC) mode of UE 402. For example, the first uplink transmission may include URLLC, or may be transmitted on URLLC resources.

[0114] Additionally or alternatively, gNB 404 may transmit scheduling information, and UE 402 may receive scheduling information. The scheduling information may indicate that uplink transmissions are mapped to a first symbol group that at least partially overlaps with downlink communications from gNB 404 (e.g., PDSCH messages and / or another downlink message). The scheduling information may further indicate that uplink transmissions are excluded from a second symbol group that at least partially overlaps with reference signals from gNB 404 (e.g., DMRS, Channel State Information Reference Signal (CSI-RS), and / or another reference signal).

[0115] In some aspects, scheduling information may be included in the MAC-CE and / or another control element. Additionally or alternatively, scheduling information may be included in the DCI and / or another signal that includes information associated with uplink transmission. In some aspects, UE 402 may schedule uplink transmissions at least in part based on or otherwise based on scheduling information.

[0116] As shown in reference numeral 710, UE 402 can adjust the transmission parameters associated with uplink transmission. (See above for reference.) Figures 6A-6C The UE 402 can adjust the transmission parameters so that the transmission power of the uplink transmission is constant across the uplink transmitted symbols. Additionally or alternatively, and as in combination Figure 6D As mentioned above, UE 402 can adjust the transmission parameters so that the phase of the uplink transmission is continuous in the symbols transmitted in the uplink.

[0117] As described above, UE 402 may adjust transmission parameters at least in part based on messages received from gNB 404. Additionally or alternatively, UE 402 may adjust transmission parameters at least in part based on settings stored in UE 402's memory. For example, UE 402 may be programmed (and / or otherwise pre-configured) according to one or more standards (e.g., 3GPP specifications and / or another standard). In some aspects, UE 402 may adjust transmission parameters at least in part based on a combination of received messages and stored settings. For example, the message may trigger UE 402 to adjust transmission parameters using stored settings. Additionally or alternatively, the message may include one or more coefficients and / or other variables used by UE 402 in conjunction with stored settings to adjust transmission parameters.

[0118] In some aspects, adjusting transmission parameters may include at least one of the following: rate matching, puncturing, or power scaling of one or more symbols in uplink transmissions; modification of at least one of the MCS or power associated with downlink transmissions to UE 402; or combinations thereof. For example, as combined above Figure 6A As described above, UE 402 can adjust transmission parameters by rate matching or puncturing all symbols transmitted in the uplink, so that the transmission power of the uplink transmission is constant across the symbols transmitted in the uplink. Alternatively, and in conjunction with the above... Figure 6B As described above, UE 402 may not perform rate matching or puncturing of any symbols within uplink transmission. Therefore, UE 402 may modify at least one of the following: MCS, power associated with downlink transmission to UE 402, and / or similar parameters to compensate for suppressing rate matching and / or puncturing of any symbols during uplink transmission.

[0119] Additionally or alternatively, UE 402 can adjust its transmission parameters by rate matching at least one symbol among those transmitted on the uplink scheduled by gNB 404. (As in combination) Figure 6D As stated, when at least one symbol overlaps with a reference signal from gNB 404, UE 402 can perform rate matching by not mapping uplink transmissions to at least one symbol.

[0120] Additionally or alternatively, UE 402 can adjust transmission parameters by using at least one symbol in power-scaled uplink transmission. For example, as described above. Figure 6C As described, UE 402 can power scale at least one symbol in uplink transmission by increasing the power associated with at least one symbol for rate matching or puncturing. For example... Figure 6CAs shown, UE 402 can increase power to compensate for rate mismatch and / or puncturing of at least one symbol. Additionally or alternatively, UE 402 can power scale at least one symbol that was not rate mismatched or not punctured in uplink transmission by reducing the power associated with at least one symbol. Figure 6C As shown, UE 402 can reduce the power of at least one symbol in order to match rate matching and / or other symbols that are punctured. In some aspects, as combined above Figure 6C The UE 402 can increase the power associated with one or more symbols transmitted in the uplink and decrease the power associated with one or more other symbols transmitted in the uplink, so that the transmission power of the uplink transmission is constant for the symbols transmitted in the uplink.

[0121] As shown in conjunction with reference numeral 715, at least in part based on adjusted transmission parameters, UE 402 can transmit uplink transmissions, and gNB 404 can receive uplink transmissions. In some aspects, as described above, UE 402 can transmit uplink transmissions on PUSCH, PUCCH, RACH, SRS resources, and / or another uplink channel.

[0122] Additionally or alternatively, based at least in part on scheduling information from gNB 404, UE 402 may transmit uplink transmissions, and gNB 404 may receive uplink transmissions. For example, UE 402 may map uplink transmissions to a first symbol group that at least partially overlaps with downlink communication from gNB 404, but not to a second symbol group that at least partially overlaps with reference signals from gNB 404. In some aspects, as described above, UE 402 may transmit uplink transmissions on PUSCH, PUCCH, RACH, SRS resources, and / or another uplink channel.

[0123] In some aspects, uplink transmission may include at least one first symbol associated with full-duplex mode of UE 402 and at least one second symbol associated with half-duplex mode of UE 402. For example, uplink transmission may include at least one first symbol before at least one second symbol. Additionally or alternatively, uplink transmission may include at least one first symbol from one or more first frequencies and at least one second symbol from one or more second frequencies. In some aspects, at least one first symbol may overlap in time and / or frequency with one or more symbols used for downlink communication from gNB 404, and at least one second symbol may not overlap with one or more symbols used for uplink communication from gNB 404.

[0124] In some aspects, UE 402 can adjust the transmission parameters such that the transmission power associated with at least one first symbol is equal to the transmission power associated with at least one second symbol. For example, UE 402 can use the same transmission power for at least one first symbol as for at least one second symbol, such that there is almost no phase discontinuity between the symbol associated with the full-duplex mode of UE 402 and the symbol associated with the half-duplex mode of UE 402. Additionally or alternatively, UE 402 can use one or more padding symbols such that the phase is continuous over at least one first symbol and at least one second symbol.

[0125] By combining Figure 7 (and / or Figures 6A-6D Using the techniques described above to transmit uplink transmissions, UE 402 can reduce or even eliminate phase discontinuities, thereby improving the quality and / or reliability of uplink transmissions. Furthermore, by reducing or eliminating phase discontinuities, UE 402 can reduce the likelihood of needing to retransmit uplink transmissions, thus saving network and processing resources.

[0126] As shown above, it provides Figure 7 As an example. Other examples may differ from those regarding... Figure 7 Example of the description.

[0127] Figure 8 This is a diagram illustrating an example process 800 performed, for example, by a UE according to this disclosure. Example process 800 is an example of a UE (e.g., UE 402, UE 120, and / or another network node, such as an MT unit and / or a sub-IAB node) performing operations associated with rate matching, puncturing, and power scaling of uplink communication in full-duplex mode.

[0128] like Figure 8 As shown, in some aspects, process 800 may include adjusting transmission parameters associated with uplink transmissions from the UE such that the phase of the uplink transmission is constant over the symbols of the uplink transmission (block 810). For example, the UE (e.g., using one or more of antenna 252, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, and / or memory 282) may adjust transmission parameters associated with uplink transmissions from the UE such that the phase of the uplink transmission is constant over the symbols of the uplink transmission, as described above. In some aspects, adjusting transmission parameters includes at least one of: rate matching, puncturing, or power scaling of one or more symbols in the uplink transmission; modification of at least one of the MCS or power associated with downlink transmissions to the UE; or combinations thereof.

[0129] like Figure 8As further shown, in some aspects, process 800 may include transmitting uplink transmissions to a base station (e.g., gNB 404, base station 110, and / or another network node, such as CU, DU, and / or parent IAB node) at least in part based on adjusted transmission parameters (box 820). For example, a UE (e.g., using one or more of antenna 252, transmission processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, and / or memory 282) may transmit uplink transmissions to the base station at least in part based on adjusted transmission parameters, as described above.

[0130] Process 800 may include additional aspects, such as any single aspect or any combination of aspects as described below and / or related to one or more other processes described elsewhere herein.

[0131] In the first aspect, the uplink transmits messages on resources including PUSCH, PUCCH, RACH, or SRS.

[0132] In the second aspect, the transmission parameters are adjusted, either alone or in combination with the first aspect, at least in part, based on settings stored in the UE's memory.

[0133] In the third aspect, the transmission parameters are adjusted, either alone or in combination with one or more of the first and second aspects, at least in part, based on messages received from the base station (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).

[0134] In the fourth aspect, alone or in combination with one or more of the first to third aspects, the message includes a configuration for rate matching or puncturing of at least one symbol in uplink transmission.

[0135] In the fifth aspect, the transmission parameters are adjusted, either alone or in combination with one or more of the first to fourth aspects, through rate matching or puncturing of all symbols transmitted in the uplink.

[0136] In the sixth aspect, either alone or in combination with one or more of the first to fifth aspects, rate matching or puncturing is not performed on any symbol within the uplink transmission.

[0137] In the seventh aspect, the transmission parameters are adjusted by rate matching at least one of the symbols scheduled by the base station for uplink transmission, either alone or in combination with one or more of the first to sixth aspects, and rate matching at least one symbol includes not mapping the uplink transmission to at least one symbol when at least one symbol overlaps with a reference signal from the base station.

[0138] In the eighth aspect, the transmission parameters are adjusted by power scaling of at least one symbol in the uplink transmission, either alone or in combination with one or more of the first to seventh aspects.

[0139] In the ninth aspect, power scaling of at least one symbol in an uplink transmission, either alone or in combination with one or more of the first to eighth aspects, includes increasing the power associated with the at least one symbol.

[0140] In the tenth aspect, power scaling of at least one symbol in an uplink transmission, either alone or in combination with one or more of the first to tenth aspects, includes reducing the power associated with at least one symbol.

[0141] In the eleventh aspect, uplink transmission is associated with the full-duplex mode of the UE, either alone or in combination with one or more of the first to tenth aspects.

[0142] In the twelfth aspect, either alone or in combination with one or more of the first to eleventh aspects, when in full-duplex mode, the UE transmits and receives simultaneously at the same frequency bandwidth.

[0143] In the thirteenth aspect, alone or in combination with one or more of the first to twelfth aspects, when in full-duplex mode, the UE transmits a first symbol group and receives a second symbol group in the same frequency bandwidth, wherein the first symbol group and the second symbol group are separated in time by less than a threshold.

[0144] In the fourteenth aspect, alone or in combination with one or more of the first to thirteenth aspects, when in full-duplex mode, the UE transmits a first symbol group in a first frequency bandwidth and simultaneously receives a second symbol group in a second frequency bandwidth, wherein the first frequency bandwidth and the second frequency bandwidth are separated in frequency by a threshold.

[0145] In the fifteenth aspect, either alone or in combination with one or more of the first to fourteenth aspects, the uplink transmission includes at least one first symbol associated with the full-duplex mode of the UE and at least one second symbol associated with the half-duplex mode of the UE.

[0146] In the sixteenth aspect, the transmission parameters are adjusted, either alone or in combination with one or more of the first to fifteenth aspects, such that the transmission power associated with at least one first symbol is equal to the transmission power associated with at least one second symbol.

[0147] although Figure 8 Example boxes for process 800 are shown, but in some respects, process 800 may include additional boxes, fewer boxes, different boxes, or different from those shown. Figure 8The boxes shown are arranged in different ways. Alternatively, two or more boxes of process 800 may be executed in parallel.

[0148] Figure 9 This is a diagram illustrating an example process 900 performed, for example, by a base station according to this disclosure. Example process 900 is an example of a base station (e.g., gNB 404, base station 110, and / or another network node, such as CU, DU, and / or parent IAB node) performing operations associated with rate matching, puncturing, and power scaling of uplink communication in full-duplex mode.

[0149] like Figure 9 As shown, in some aspects, process 900 may include sending a message to the UE (e.g., UE 402, UE 120, and / or another network node, such as an MT unit and / or a sub-IAB node) triggering the UE to adjust transmission parameters associated with uplink transmissions from the UE, such that the phase of the uplink transmission is constant over the symbols of the uplink transmission (box 910). 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 send a message to the UE triggering the UE to adjust transmission parameters associated with uplink transmissions from the UE, such that the transmit power of the uplink transmission is constant over the symbols of the uplink transmission, as described above. In some aspects, adjusting the transmission parameters includes at least one of: rate matching, puncturing, or power scaling of one or more symbols in the uplink transmission, modification of the MCS, or at least one of the power associated with downlink transmissions to the UE; or combinations thereof.

[0150] like Figure 9 As further illustrated, in some aspects, process 900 may include receiving uplink transmissions from the UE at least in part based on a transmission message (block 920). For example, a base station (e.g., using one or more of antenna 234, demodulator 232, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246) may receive uplink transmissions from the UE at least in part based on a transmission message, as described above.

[0151] Process 900 may include additional aspects, such as any single aspect or any combination of aspects as described below and / or related to one or more other processes described elsewhere herein.

[0152] In the first aspect, the uplink transmits messages on resources including PUSCH, PUCCH, RACH, or SRS.

[0153] In the second aspect, alone or in combination with the first aspect, the message includes a configuration for rate matching or puncturing at least one symbol in an uplink transmission.

[0154] In the third aspect, either alone or in combination with one or more of the first and second aspects, all symbols transmitted in the uplink are rate-matched or punched.

[0155] In the fourth aspect, either alone or in combination with one or more of the first to third aspects, no symbols in the uplink transmission are rate-matched or punctured.

[0156] In the fifth aspect, either alone or in combination with one or more of the first to fourth aspects, at least one symbol in the uplink transmission is rate-matched such that when at least one symbol overlaps with a reference signal from the base station, the uplink transmission is not mapped to at least one symbol.
