[0001] Cross-references to related applications

[0002] This application claims the benefit of U.S. Patent Application No. 17 / 112,934, filed December 4, 2020, entitled “BEAM ADJUSTMENT / CANCELLATIONRULES FOR NON-COMPATIBLE UL / DL BEAMS”, which is expressly incorporated herein by reference in its entirety. Background Technology Technical Field

[0003] This disclosure generally relates to communication systems, and more particularly to communication in full-duplex mode in wireless communication systems.

[0004] introduction

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources. 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, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0006] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the city, country, region, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the continuous evolution of mobile broadband, promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements to 5G NR technology. These improvements can also be applied to other multiple access technologies and telecommunications standards that adopt them. Summary of the Invention

[0007] The following provides a brief overview of one or more aspects to offer a basic understanding of such aspects. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify the key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as an introduction to the more detailed description that follows.

[0008] In one aspect of this disclosure, a method, computer-readable medium, and apparatus are provided for a user equipment (UE). The apparatus can receive first scheduling information regarding a first resource associated with a first beam based on a half-duplex mode. The apparatus can receive second scheduling information regarding a second resource associated with a second beam, which is incompatible with the first beam for full-duplex communication including time-overlapping downlink reception and uplink transmission. Furthermore, the apparatus can adjust communication in response to the incompatibility of the first beam with the second beam for full-duplex communication.

[0009] In another aspect of this disclosure, a method, computer-readable medium, and apparatus at a base station are provided. The apparatus can transmit first scheduling information regarding a first resource associated with a first beam based on a half-duplex mode. The apparatus can transmit second scheduling information regarding a second resource associated with a second beam, which is incompatible with the first beam for full-duplex communication including time-overlapping downlink transmissions and uplink receptions. Furthermore, the apparatus can adjust communication in response to the incompatibility of the first beam with the second beam for full-duplex communication.

Certain illustrative features of these one or more aspects are set forth in detail in the following description and drawings. However, these features merely indicate a few of the various ways in which the principles of these various aspects may be employed, and this description is intended to cover all such aspects and their equivalents.

[0029] The detailed description that follows, taken in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent only the configurations in which the concepts described herein can be practiced. This detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0030] Several aspects of a telecommunications system will now be described with reference to various apparatuses and methods. These apparatuses and methods will be described in detail below and explained in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using electronic hardware, computer software, or any 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.

[0031] As an example, an element, or any part of an element, or any combination of elements, may be implemented as a "processing system" including one or more processors. Examples of processors include: microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. One or more processors in a processing system can execute software. Software should be broadly interpreted as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description languages, or other terms.

[0032] Accordingly, in one or more example embodiments, the described functionality can be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality can be stored or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media can be any available medium accessible to a computer. By way of example and not limitation, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage, magnetic disk storage, other magnetic storage devices, combinations of computer-readable media of the types described above, or any other medium capable of being used to store computer-executable code in the form of instructions or data structures accessible to a computer.

[0033] User equipment (UE) and / or base station can communicate in full-duplex mode, in which uplink and downlink communications are exchanged at overlapping times in the same frequency band, in partially overlapping frequency bands, or in separate frequency bands. The UE and the base station can use one or more directional beams to exchange communications. The UE can perform an ongoing uplink or downlink transmission in half-duplex mode based on first scheduling information received from the base station. At overlapping times, the base station can schedule additional transmissions in the opposite direction using second scheduling information. The scheduled beams for transmissions in both directions (i.e., uplink and downlink) may be incompatible with each other for full-duplex communication (due to, for example, the inability to cancel or adequately mitigate the associated self-interference between concurrent transmissions and receptions on these two beams). A first beam can be selected based on a first metric for half-duplex communication (e.g., Reference Signal Received Power (RSRP)), and a second beam can be selected based on a second metric for full-duplex communication (e.g., Signal-to-Interference and Noise Ratio (SINR)). Therefore, the second metric can take into account self-interference not considered in the first metric. For example, a half-duplex mode beam can be based on the best RSRP beam in a candidate beam set (e.g., downlink beam 1). Conversely, a full-duplex mode beam pair can be based on the best SINR beam pair with the highest signal strength, and for this best SINR beam pair, the transmit (Tx) beam produces small self-interference with its paired receive (Rx) beam (e.g., a beam pair including downlink beam 3 and uplink beam 5). If a first transmission is scheduled for half-duplex downlink beam 1 at a time overlapping with a second transmission, and the second transmission is scheduled for UL beam 5 from a full-duplex beam pair, then beam 5 can produce self-interference with downlink reception on beam 1. Therefore, beam 5 can be considered incompatible with beam 1 for full-duplex communication involving time-overlapping transmissions and receptions. The aspects described herein relate to methods for handling incompatible uplink and downlink beams.

[0034] Figure 1 This is a diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also known as a wireless wide area network (WWAN)) includes base station 102, UE 104, evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). Base station 102 may include macrocells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macrocells include base stations. Small cells include femtocells, picocells, and microcells.

[0035] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can interface with core network 190 via a second backhaul link 184. Among other functions, base station 102 can also perform one or more of the following functions: user data delivery, radio channel cryptography and cryptography decoding, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of Non-Access Stratum (NAS) messages, NAS node selection, synchronization, Radio Access Network (RAN) sharing, Multimedia Broadcast Multicast Service (MBMS), subscriber and equipment tracking, RAN Information Management (RIM), paging, location, and delivery of alarm messages. Base station 102 can communicate with each other directly or indirectly (e.g., via EPC 160 or core network 190) on third backhaul link 134 (e.g., X2 interface). First backhaul link 132, second backhaul link 184 and third backhaul link 134 can be wired or wireless.

[0036] Base station 102 can wirelessly communicate with UE 104. Each base station 102 can provide communication coverage for its respective geographical coverage area 110. Overlapping geographical coverage areas 110 may exist. For example, small cell 102' may have coverage areas 110' that overlap with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. The heterogeneous network may also include a Home Evolved B Node (eNB) (HeNB) that can provide services to a restricted group referred to as a Closed Subscriber Group (CSG). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also known as forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity. These communication links may use one or more carriers. For each carrier allocated in a total of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum with a bandwidth of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.). These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carrier may be referred to as the secondary cell (SCell).

[0037] Some UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 may use DL / UL WWAN spectrum. D2D communication link 158 may use one or more sidelink channels, such as the Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be achieved through a wide variety of wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0038] The wireless communication system may further include a Wi-Fi access point (AP) 150 communicating with a Wi-Fi station (STA) 152 via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) before communication to determine whether the channel is available.

[0039] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) used by Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can enhance access network coverage and / or increase access network capacity.

[0040] The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). The frequencies between FR1 and FR2 are generally referred to as the mid-band frequencies. Although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes arise regarding FR2; although different from the Very High Frequency (EHF) band (30GHz–300GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is often (interchangeably) referred to as the “millimeter wave” band in various documents and articles.

[0041] In light of the foregoing, unless otherwise stated, it should be understood that, as used herein, the term "sub-6GHz" and the like can broadly refer to frequencies less than 6GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise stated, it should be understood that, as used herein, the term "millimeter wave" and the like can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, or within the EHF band.

[0042] Whether it is a small cell 102' or a large cell (e.g., a macro base station), base station 102 may include and / or be referred to as an eNB, gB node (gNB), or another type of base station. Some base stations (such as gNB 180) may operate in conventional sub-6 GHz spectrum, millimeter wave frequencies, and / or near-millimeter wave frequencies to communicate with UE 104. When gNB 180 operates in millimeter wave frequencies or near-millimeter wave frequencies, gNB 180 may be referred to as a millimeter wave base station. Millimeter wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short range. Base station 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.

[0043] Base station 180 may transmit beamformed signals to UE 104 in one or more transmission directions 182'. UE 104 may receive beamformed signals from base station 180 in one or more reception directions 182'. UE 104 may also transmit beamformed signals to base station 180 in one or more transmission directions. Base station 180 may receive beamformed signals from UE 104 in one or more reception directions. Base station 180 / UE 104 may perform beam training to determine the optimal reception and transmission directions for each of base station 180 / UE 104. The transmission and reception directions of base station 180 may be the same or different. The transmission and reception directions of UE 104 may be the same or different.

[0044] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Generally, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are delivered through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. The BM-SC 170 provides functionality for MBMS user service provisioning and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 can be used to distribute MBMS traffic to base station 102 within a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0045] The core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and the core network 190. Generally, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP services 197. IP services 197 may include the Internet, intranet, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming (PSS) services, and / or other IP services.

[0046] Base stations may include and / or be referred to as gNB, B-node, eNB, access point, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), transmit / receive point (TRP), or some other suitable term. Base station 102 provides UE 104 with access to EPC 160 or core network 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptop devices, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet devices, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similar functional devices. Some UE 104 may be referred to as IoT devices (e.g., parking timers, oil pumps, ovens, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable term.

[0047] Refer again Figure 1 In some aspects, UE 104 may include a beam management component 198, which may be configured to receive first scheduling information regarding first resources for transmission using a first beam based on a half-duplex mode. Beam management component 198 may be configured to receive second scheduling information regarding second resources associated with a second beam, which is incompatible with the first beam for full-duplex communication including time-overlapping downlink reception and uplink transmission. Furthermore, beam management component 198 may be configured to adjust communication in response to the incompatibility of the first beam with the second beam for full-duplex communication. In some aspects, base station 180 includes a beam management component 199, which may be configured to transmit first scheduling information regarding first resources for transmission using the first beam based on a half-duplex mode. Beam management component 199 may be configured to transmit second scheduling information regarding second resources associated with a second beam, which is incompatible with the first beam for full-duplex communication including time-overlapping downlink reception and uplink transmission. Furthermore, the beam management component 199 can be configured to adjust communication in response to incompatibility between the first beam and the second beam for full-duplex communication. Although the following description may focus on 5G NR, the concepts described herein are applicable to other similar fields such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0048] Figure 2A This is a diagram 200 illustrating an example of the first subframe within the 5G NR frame structure. Figure 2B Figure 230 is an example illustrating the DL channel within a 5G NR subframe. Figure 2C This is a diagram 250 illustrating an example of the second subframe within the 5G NR frame structure. Figure 2D Figure 280 illustrates an example of the UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD), where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to either DL or UL; or it can be Time Division Duplex (TDD), where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to both DL and UL. Figure 2A , 2C In the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (mostly DL) and subframe 3 is configured with slot format 1 (all UL), where D is DL, U is UL, and F is for flexible use between DL and UL. Although subframes 3 and 4 are shown as having slot formats 1 and 28, respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are all DL and all UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The UE is configured to have a slot format via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling). Note that the following description also applies to 5G NR frame structures for TDD.

[0049] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10ms) can be divided into 10 equally sized subframes (1ms). Each subframe may include one or more time slots. Subframes may also include mini-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 7 or 14 symbols, depending on the time slot configuration. For time slot configuration 0, each time slot may include 14 symbols, while for time slot configuration 1, each time slot may include 7 symbols. Symbols on the DL can be Cyclic Prefix (CP) Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL can be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the time slot configuration and parameter design. For slot configuration 0, different parameter designs μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For slot configuration 1, different parameter designs 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Correspondingly, for slot configuration 0 and parameter design μ, there are 14 symbols per slot and 2 symbols per subframe. μ Each time slot. The subcarrier spacing and symbol length / duration vary depending on the design parameters. The subcarrier spacing can be equal to 2. μ *15kHz, where μ is the parameter design from 0 to 4. Thus, parameter design μ = 0 has a subcarrier spacing of 15kHz, while parameter design μ = 4 has a subcarrier spacing of 240kHz. Symbol length / duration is inversely correlated with subcarrier spacing. Figures 2A to 2D An example is provided with a slot configuration of 0 (14 symbols per slot) and a parameter design of μ=2 (4 slots per subframe). The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within the frame set, there may be one or more different bandwidth portions (BWPs) that are frequency-division multiplexed (see [link to relevant documentation]). Figure 2B Each BWP can have specific parameter designs.

[0050] A resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) extending 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0051] like Figure 2AAs explained in the text, some REs carry reference (pilot) signals (RS) for the UE. RSs may include demodulation RS (DM-RS) for channel estimation at the UE (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS). RSs may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0052] Figure 2B Examples of various DL channels within a subframe of a frame are explained. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising 6 RE Groups (REGs), each REG comprising 12 coherent REs in the OFDM symbols of the RB. A PDCCH within a BWP may be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a shared search space, a UE-specific search space) during PDCCH monitoring on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies spanning the channel bandwidth. The Primary Synchronization Signal (PSS) may be located within symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identity. The Secondary Synchronization Signal (SSS) may be located within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the Physical Layer Cell Identity Group Number and radio frame timing. Based on the Physical Layer Identity and the Physical Layer Cell Identity Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted via the PBCH (such as System Information Block (SIB)), and paging messages.

[0053] As in Figure 2CAs explained, some REs carry DM-RS for channel estimation at the base station (indicated as R for a specific configuration, but other DM-RS configurations are possible). The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the first or first two symbols of the PUSCH. The PUCCH DM-RS can be transmitted in different configurations depending on whether a short or long PUCCH is being transmitted and on the specific PUCCH format used. The UE can transmit a probe reference signal (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the combs. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0054] Figure 2D Examples of various UL channels within a subframe of a frame are explained. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) information (ACK / NACK (NACK)) feedback. The PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI.

[0055] Figure 3This is a block diagram showing the communication between base station 310 and UE 350 in the access network. In the DL, IP packets from EPC 160 can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functionality. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Serving Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration of UE measurement reports; PDCP layer functionality associated with header compression / decompression, security (cryptography, cryptographic decoding, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with upper-layer packet data unit (PDU) delivery, error correction via ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing MAC SDUs onto transport blocks (TBs), demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority differentiation.

[0056] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functionality associated with various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) decoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time-domain OFDM symbol stream. The OFDM stream is spatially precoded to generate multiple spatial streams. Channel estimates from channel estimator 374 can be used to determine coding and modulation schemes and for spatial processing. The channel estimates can be derived from reference signals and / or channel condition feedback transmitted by UE 350. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can modulate an RF carrier with the corresponding spatial stream for transmission.

[0057] At UE 350, each receiver 354RX receives signals via its respective antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides this information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, they can be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, along with the reference signal, are recovered and demodulated by determining the signal constellation points most likely to be transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. These soft decisions are then decoded and deinterleaved to recover the original data and control signals transmitted by base station 310 over the physical channel. This data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0058] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, cipher decoding, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0059] Similar to the functionality described in conjunction with DL transmissions performed by base station 310, controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) capture, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (cryptography, cryptographic decoding, integrity protection, integrity verification); RLC layer functionality associated with upper-layer PDU delivery, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing MAC SDUs onto TBs, demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority differentiation.

[0060] The channel estimate derived by the channel estimator 358 from the reference signal or feedback transmitted by the base station 310 can be used by the TX processor 368 to select an appropriate coding and modulation scheme and to facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0061] UL transmissions are processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318RX receives signals via its corresponding antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides that information to the RX processor 370.

[0062] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, cipher decoding, header decompression, and control signal processing to recover IP packets from the UE 350. IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0063] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform and Figure 1 The 198 combines various aspects.

[0064] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform operations related to... Figure 1 The 199 combines various aspects.

[0065] Wireless communication systems can be configured to share available system resources and provide various telecommunications services (e.g., telephone, video, data, messaging, broadcasting, etc.) based on multiple access technologies that support communication with multiple users. Full-duplex operation (where wireless devices exchange time-overlapping uplink and downlink communications) enables more efficient use of the wireless spectrum. Full-duplex operation can include simultaneous transmission and reception in the same frequency range, partially overlapping frequency ranges, or separate frequency ranges. In some examples, the frequency range can be a mmW frequency range, such as frequency range 2 (FR2). In some examples, the frequency range can be a sub-6 GHz frequency range, such as frequency range 1 (FR1). The aspects given herein can also be applied to other frequency ranges. Full-duplex capability can be supported at the base station and / or UE. For example, a UE can transmit uplink communication from one antenna panel and receive downlink communication from another antenna panel. As another example, a base station can transmit from one antenna panel to one UE and receive from another UE using another antenna panel. As yet another example, a base station can transmit from one antenna panel to one UE and receive from the same UE using another antenna panel. In some examples, full-duplex communication can be conditional on beam or spatial separation or other conditions.

[0066] Full-duplex communication reduces latency. For example, full-duplex operation allows a UE to receive downlink signals in uplink time slots only, reducing downlink communication latency. Full-duplex communication improves spectral efficiency, such as per cell or per UE. Full-duplex communication enables more efficient use of radio resources.

[0067] Figures 4A-4C The various modes of full-duplex communication are explained. Full-duplex communication supports the transmission and reception of information in overlapping time bands, partially overlapping frequency bands, or separate frequency bands. In this way, spectral efficiency can be improved compared to half-duplex communication, which supports uplink and downlink communication that transmits or receives information in one direction at a time without overlap. Due to the simultaneous Tx / Rx nature of full-duplex communication, the UE or base station may experience self-interference caused by signal leakage from its local transmitter to its local receiver. Additionally, the UE or base station may experience interference from other devices, such as transmissions from a second UE or a second base station. Such interference (e.g., self-interference or interference caused by other devices) may affect communication quality or even lead to data loss.

[0068] Figure 4A A first example of full-duplex communication 400 is shown, wherein a first base station 402a is in full-duplex communication with a first UE 404a and a second UE 406a. The first base station 402a is a full-duplex base station, while the first UE 404a and the second UE 406a can be configured as half-duplex or full-duplex UEs. The second UE 406a can transmit a first uplink signal to the first base station 402a and other base stations (such as a second base station 408a adjacent to the second UE 406a). The first base station 402a concurrently transmits downlink signals to the first UE 404a while receiving uplink signals from the second UE 406a. The base station 402a may experience self-interference from its receiving antenna, which receives some downlink signals being transmitted to the UE 404a from the receiving antenna that receives uplink signals from the UE 406a. The base station 402a may experience additional interference caused by signals from the second base station 408a. Interference may also occur at the first UE 404a based on signals from the second base station 408a and uplink signals from the second UE 406a.

[0069] Figure 4B A second example of full-duplex communication 410 is shown, wherein a first base station 402b and a first UE 404b are in full-duplex communication. In this example, the first base station 402b is a full-duplex base station, and the first UE 404b is a full-duplex UE. The first base station 402b and UE 404b can concurrently receive and transmit time-overlapping communications in the same frequency band. The base station and UE may each experience self-interference, where signals transmitted from the device are leaked to the receiver of the same device. The first UE 404b may experience additional interference based on one or more signals transmitted from a second UE 406b and / or a second base station 408b adjacent to the first UE 404b.

[0070] Figure 4CA third example of full-duplex communication 420 is shown, wherein a first UE 404c is a full-duplex UE communicating with a first base station 402c and a second base station 408c. The first base station 402c and the second base station 408c can be used as multiple transmit / receive points (multiple TRPs) for UL and DL communication with UE 404c. The second base station 408c can communicate with a second UE 406c. Figure 4C In this configuration, the first UE 404c can concurrently transmit uplink signals to the first base station 402c while receiving downlink signals from the second base station 408c. The first UE 404c may experience self-interference caused by the simultaneous transmission of the first and second signals; for example, the uplink signal may leak to the UE's receiver (e.g., be received by the UE's receiver). The first UE 404c may experience additional interference from the second UE 406c.

[0071] Full-duplex communication can occur within the same frequency band. Uplink and downlink communication can occur in different frequency subbands, the same frequency subband, or partially overlapping frequency subbands. Figure 5 A first example 500 and a second example 510 of in-band full-duplex (IBFD) resources, and a third example 520 of sub-band full-duplex resources, have been described. In IBDF, signals can be transmitted and received in overlapping times and overlapping frequencies. As shown in the first example 500, the time and frequency allocation of UL resource 502 may completely overlap with the time and frequency allocation of DL resource 504. In the second example 510, the time and frequency allocation of UL resource 512 may partially overlap with the time and frequency allocation of DL resource 514.

[0072] In contrast to subband frequency division duplex (FDD), uplink and downlink resources can overlap in time using different frequencies, as shown in the third example 520. In the third example 520, UL resource 522 is separated from DL resource 524 by a guard band 526. The guard band can be a frequency resource provided between UL resource 522 and DL resource 524, or a gap in frequency resources. Separating UL frequency resources from DL frequency resources using a guard band can help reduce self-interference. UL resources and DL resources adjacent to each other correspond to a guard band width of 0. Since the output signal (e.g., from the UE transmitter) can extend beyond the UL resource, the guard band reduces interference experienced by the UE. Subband FDD can also be referred to as “flexible duplex”.

[0073] A base station can schedule a UE for half-duplex transmission or reception using a half-duplex beam, and can also schedule a UE for transmission / reception using a full-duplex beam. Resources can overlap in time, but half-duplex beams may be incompatible with full-duplex beams for overlapping full-duplex transmission and reception. These beams may be incompatible because, for example, the associated self-interference between concurrent transmission and reception on the two beams cannot be cancelled or sufficiently mitigated. Half-duplex beams can be selected based on a first metric for half-duplex communication (e.g., Reference Signal Received Power (RSRP)), and full-duplex beams can be selected based on a second metric for full-duplex communication (e.g., Signal-to-Interference and Noise Ratio (SINR)). Thus, the second metric can take into account self-interference not considered in the first metric. For example, a half-duplex mode beam can be selected based on the best RSRP beam (e.g., beam 1) in a candidate beam set. Conversely, full-duplex mode beam pairs can be based on the optimal SINR beam pair with the highest signal strength, and for this optimal SINR beam pair, the transmit (Tx) beam produces small self-interference with its paired receive (Rx) beam (e.g., a beam pair including downlink beam 3 and uplink beam 5). If the first transmission is scheduled for half-duplex downlink beam 1 at a time overlapping with the second transmission, and the second transmission is scheduled for UL beam 5 from the full-duplex beam pair, then beam 5 can produce self-interference with downlink reception on beam 1. Therefore, beam 5 can be considered incompatible with beam 1 for full-duplex communication involving time-overlapping transmissions and receptions. The aspects described herein relate to methods for handling incompatible uplink and downlink beams.

[0074] Figure 6 This is a communication flow 600 between UE 602 and base station 604, which illustrates example aspects of beam adjustment or cancellation for such incompatible uplink and downlink beams.

[0075] In some respects, UE 602 or base station 604 may apply rules to determine the downlink beam to be paired with an existing uplink beam. For example, to illustrate this concept, base station 604 may, for instance, schedule UE 602 for uplink transmissions at 606. Uplink transmissions may include ongoing or periodic transmissions, such as CG transmissions or uplink feedback transmissions for a semi-persistent scheduling (SPS) configuration associated with one of UE 602's beams 601. CG or uplink feedback resources may be configured / scheduled to transmit periodically in half-duplex mode using the indicated beam (e.g., a half-duplex beam or a beam selected based on a half-duplex metric (such as RSRP) and without considering self-interference). At 608, base station 604 may also schedule downlink transmissions to UE 602, such as CORESET / PDSCH / CSI-RS on a downlink beam. A downlink beam can be a beam that is part of a full-duplex beam pair selected based on one or more full-duplex metrics, such as SINR or self-interference between beam pairs. If a downlink beam scheduled at 608 is incompatible with an uplink beam scheduled at 606 for full-duplex communication, UE 602 and / or base station 604 can apply one or more rules to reset the downlink or uplink beam, or cancel transmission / reception, to avoid self-interference caused by overlapping uplink transmissions and downlink receptions on incompatible beams. For example, UE 602 or base station 604 can apply rules to determine the downlink beam to be paired with an existing uplink beam.

[0076] In some aspects, UE 602 or base station 604 can apply rules to determine the uplink beam to be paired with an existing downlink beam. At 606, base station 604 can schedule UE 602 to receive downlink transmissions delivered in half-duplex mode using a half-duplex beam (e.g., a beam selected based on a half-duplex metric such as RSRP and without considering self-interference). For example, downlink transmissions may include ongoing or periodic downlink transmissions, such as downlink SPS transmissions, or downlink feedback for a CG configuration from the UE. At 608, base station 604 can schedule UE 602 for uplink transmissions, such as PUCCH / PUSCH / SRS utilizing an uplink beam (e.g., one of beams 601) that is part of a full-duplex beam pair. Full-duplex beam pairs can be selected based on one or more full-duplex metrics, including self-interference between beams in the beam pair. If the uplink beam scheduled at 608 is incompatible with the downlink beam scheduled at 606 for full-duplex communication, UE 602 and / or base station 604 may apply one or more rules to reset the downlink or uplink beam, or cancel transmission / reception, to avoid self-interference caused by overlapping uplink transmission and downlink reception on incompatible beams. For example, UE 602 or base station 604 may apply rules to determine the uplink beam to be paired with the existing downlink beam.

[0077] As explained in 606, UE 602 can receive from base station 604 first scheduling information regarding a first resource for transmission (e.g., uplink or downlink) using a first beam based on half-duplex mode, and base station 604 can transmit this first scheduling information to UE 602. The scheduling information may be for periodic resources, such as based on CG, SPS, or feedback based on CG or SPS. In 608, UE 602 can receive from base station 604 second scheduling information regarding a second resource associated with a second beam that is incompatible with full-duplex communication (e.g., transmission and reception in the same frequency range, in partially overlapping frequency ranges, or in separate frequency ranges), and base station 604 can transmit this second scheduling information to UE 602.

[0078] As explained in 609A, UE 602 can determine that a first beam associated with a first resource scheduled in 606 is incompatible with full-duplex communication using a second beam associated with a second resource scheduled in 608. For example, the UE can determine that a transmission on the first beam will interfere with concurrent reception on the second beam, or that a transmission on the second beam will interfere with concurrent reception on the second beam. Similarly, base station 604 can detect or determine in 609B that these two beams are incompatible for uplink / downlink communication in full-duplex mode.

[0079] At 610, UE 602 can adjust communication in response to incompatibility between the first beam and the second beam for full-duplex communication. In one aspect, adjusting communication may include resetting the first beam in response to incompatibility between the first beam and the second beam for full-duplex communication. For example, if the downlink beam scheduled at 608 is incompatible with the uplink beam scheduled at 606, the UE can reset the uplink beam. In some aspects, base station 604 may indicate a full-duplex beam pair in the TCI state of downlink transmissions scheduled using a bidirectional beam pair (e.g., scheduled at 608): one beam for downlink and one beam for uplink. As explained at 614, UE 602 may reset the uplink beam for the first resource scheduled at 606 at 614 based on the uplink beam indicated by the TCI state of the full-duplex beam pair scheduled at 608. At 620, base station 604 may similarly reset the uplink beam.

[0080] In another example, if the uplink beam scheduled at 608 is incompatible with the downlink beam scheduled at 606, the UE can reset the downlink beam. In some aspects, base station 604 can indicate a full-duplex beam pair in the TCI state of uplink transmissions scheduled using a bidirectional beam pair (e.g., scheduled at 608): one beam for downlink and one beam for uplink. As explained at 614, UE 602 can reset the downlink beam for the first resource scheduled at 606 at 614 based on the downlink beam indicated by the TCI state of the bidirectional beam pair from the full-duplex beam pair scheduled at 608. At 620, base station 604 can similarly reset the downlink beam.

[0081] In some aspects, UE 602 may find information in the Beam Failure Detection (BFD) / Radio Link Measurement (RLM) Reference Signal (RS) configuration, such as indicating the uplink beam paired with the full-duplex downlink beam associated with the downlink transmission scheduled in 608 in the Interference Measurement Resource (IMR) RS configuration. At 614, the UE may reset the uplink beam used for the transmission scheduled in 606 to the paired uplink beam based on this information. For example, in full-duplex mode, UE 602 may use the reset beam to concurrently transmit uplink transmission 628 with receiving downlink transmission 630. At 620, base station 604 may similarly reset the uplink beam. At 614, the UE may similarly reset the downlink beam used for the transmission scheduled in 606 to the paired downlink beam based on this information. For example, in full-duplex mode, UE 602 may use the reset beam to concurrently receive downlink transmission 626 with transmitting uplink transmission 632. At 620, base station 604 can similarly reset the downlink beam.

[0082] In some aspects, at 614, UE 602 can reset the uplink beam used for the uplink transmission scheduled at 606 based on a Self-Interference Measurement (SIM) / Beam Management (BM) measurement report. For example, at 608, the UE can find candidate uplink beams that pair with the full-duplex downlink beams associated with the scheduled downlink transmission in the latest measurement information. UE 602 can reset the uplink beam or use the uplink beam based on the latest measurement information. For example, in full-duplex mode, UE 602 can use the reset beam to concurrently transmit uplink transmission 628 with receiving downlink transmission 630. At 620, base station 604 can similarly reset the uplink beam. At 614, the UE can similarly reset the downlink beam used for the transmission scheduled at 606 to a paired downlink beam based on the latest measurement information. For example, in full-duplex mode, UE 602 can use the reset beam to concurrently receive downlink transmission 626 with transmitting uplink transmission 632. At 620, base station 604 can similarly reset the downlink beam.

[0083] In some respects, if a RACH timing overlaps with a downlink SSB in full-duplex mode, UE 602 can use the beam associated with the transmitted RACH preamble to pair with the full-duplex downlink beam associated with (e.g., scheduled in 608) the scheduled downlink transmission. Therefore, at 614, UE 602 can reset the uplink beam for the transmission scheduled in 606 for the first resource based on the RACH preamble beam. For example, in full-duplex mode, UE 602 can use the reset beam to concurrently transmit uplink transmission 628 with receiving downlink transmission 630. At 620, base station 604 can similarly reset the uplink beam. UE can similarly use the SSB beam to pair with the full-duplex uplink beam associated with the uplink transmission scheduled in 608 to reset the downlink beam for the transmission scheduled in 606 at 614. For example, in full-duplex mode, UE 602 can use a reset beam to concurrently receive downlink transmissions 626 while transmitting uplink transmissions 632. At 620, base station 604 can similarly reset the downlink beam.

[0084] On the other hand, adjusting communication may include adjusting the second beam for full-duplex communication. If the first beam scheduled for uplink transmission at 606 would interfere with the second beam scheduled for downlink reception at 608, UE 602 and similarly base station 604 may reset the downlink beam at 616 or 622. As an example, to illustrate the concept, if uplink transmission on the first beam would cause interference with downlink reception scheduled on the second beam, the UE may reset the downlink beam based on a TCI indication to pair with the uplink transmission. The uplink transmission may be for ongoing or periodic uplink transmissions, such as uplink CG transmissions or uplink feedback transmissions for SPS configuration that are periodically transmitted in full-duplex mode using TCI states including bidirectional beam pairs: one beam for downlink and one beam for uplink. At 616, UE 602 may reset the downlink beam based on a TCI state indication to pair with the CG or feedback for SPS. For example, in full-duplex mode, UE 602 can use a reset beam to concurrently receive downlink transmission 630 while transmitting uplink transmission 632. At 622, base station 604 can similarly reset the downlink beam.

[0085] In another example, if the uplink beam scheduled at 608 is incompatible with the downlink beam scheduled at 606, the UE can reset the uplink beam. In some aspects, base station 604 can indicate a full-duplex beam pair in the TCI state of a downlink transmission scheduled using a bidirectional beam pair (e.g., scheduled at 608): one beam for the downlink and one beam for the uplink. As explained at 616, UE 602 can reset the uplink beam for the second resource scheduled at 608 based on the uplink beam indicated by the TCI state of the full-duplex beam pair scheduled at 606. UE 602 can use the reset uplink beam in full-duplex mode to concurrently transmit uplink transmission 632 while receiving downlink transmission 626. At 622, base station 604 can similarly reset the uplink beam.

[0086] In some respects, UE 602 can find information in its BFD / RLM RS configuration, such as its downlink beam paired with the full-duplex uplink beam associated with the uplink transmission in its Channel Measurement Resource (CMR) RS configuration. If the downlink beam scheduled at 608 is incompatible with the uplink beam scheduled at 606, UE 602 can reset the downlink beam at 616 based on this information. For example, in full-duplex mode, UE 602 can use the reset beam to concurrently receive downlink transmission 630 with uplink transmission 632. At 622, base station 604 can similarly reset the downlink beam. In some respects, if the uplink beam scheduled at 608 is incompatible with the downlink beam scheduled at 606, the UE can reset the uplink beam at 616 based on information in the BFD / RLM RS configuration, which is based on the uplink beam paired with the full-duplex downlink beam associated with, for example, the downlink transmission scheduled at 606, in the IMR RS configuration. The UE 602 can use the reset uplink beam in full-duplex mode to concurrently transmit uplink transmissions at 632 while receiving downlink transmissions at 626. At 622, the base station 604 can similarly reset the uplink beam.

[0087] In some aspects, if the downlink beam scheduled at 608 is incompatible with the uplink beam scheduled at 606, UE 602 can reset the downlink beam at 616 based on the SIM / BM measurement report. UE 602 can find candidate downlink beams that pair with the full-duplex uplink beam associated with periodic uplink transmissions in the latest measurement information. At 616, UE 602 can reset the downlink beam based on this information. For example, in full-duplex mode, UE 602 can use the reset beam to concurrently receive downlink transmission 630 while transmitting uplink transmission 632. At 622, base station 604 can similarly reset the downlink beam. In some aspects, if the uplink beam scheduled at 608 is incompatible with the downlink beam scheduled at 606, UE 602 can reset the uplink beam at 622 based on the SIM / BM report. The UE can find candidate uplink beams that pair with the full-duplex downlink beam associated with, for example, the downlink transmission scheduled in 606, based on the latest measurement information. The UE 602 can use the reset uplink beam in full-duplex mode to concurrently transmit uplink transmission 632 while receiving downlink transmission 626. At 622, the base station 604 can similarly reset the uplink beam.

[0088] In some respects, if a RACH opportunity exists in full-duplex mode that overlaps with the downlink SSB, and if the downlink beam scheduled at 608 is incompatible with the uplink beam scheduled at 606, then UE 602 can use the SSB beam to pair with the full-duplex uplink beam associated with the uplink transmission. At 616, UE 602 can reset the downlink beam based on the SSB. For example, in full-duplex mode, UE 602 can use the reset beam to concurrently receive downlink transmission 630 while transmitting uplink transmission 632. At 622, base station 604 can similarly reset the downlink beam.

[0089] In some respects, if the uplink beam scheduled at 608 is incompatible with the downlink beam scheduled at 606, the UE can reset the uplink beam at 622 based on the RACH timing that overlaps with the downlink SSB in full-duplex mode. UE 602 can use the uplink beam associated with the transmitted RACH preamble to pair with the full-duplex downlink beam associated with the downlink transmission scheduled at 606. Therefore, the UE can reset the uplink beam based on the RACH preamble beam. UE 602 can use the reset uplink beam in full-duplex mode to concurrently transmit uplink transmission 632 with receiving downlink transmission 626. At 622, base station 604 can similarly reset the uplink beam.

[0090] In another aspect, adjusting communication may include canceling the transmission or reception of one or more transmissions based on a first resource in response to incompatibility between the first beam and the second beam for full-duplex communication, as shown in 618. In a further aspect, adjusting communication may include canceling the transmission or reception of a second resource in response to incompatibility between the first beam and the second beam for full-duplex communication. For example, if a downlink beam scheduled at 608 for receiving downlink transmissions is incompatible with an existing uplink transmission scheduled at 606, the UE may cancel or skip the reception of the downlink transmission. UE 602 may transmit uplink transmission 628 and may skip the reception of downlink transmission 630. In other aspects, if a downlink beam scheduled at 608 for receiving downlink transmissions is incompatible with an existing uplink transmission scheduled at 606, the UE may cancel or skip the transmission of the uplink transmission. UE 602 may receive downlink transmission 624 and may skip uplink transmission 628. Downlink transmissions may be dynamic or aperiodic, while uplink transmissions may be ongoing periodic transmissions. In other examples, downlink transmissions can be periodic, while uplink transmissions can be dynamic or aperiodic.

[0091] If the uplink beam scheduled in 608 for uplink transmission is incompatible with the beam scheduled in 606 for receiving existing downlink transmission, the UE may cancel or skip the reception of the downlink transmission. UE 602 may transmit uplink transmission 628 and may skip the reception of downlink transmission 630. In other aspects, if the uplink beam scheduled in 608 for uplink transmission is incompatible with the beam scheduled in 606 for receiving existing downlink transmission, the UE may cancel or skip the transmission of the uplink transmission. UE 602 may receive downlink transmission 624 and may skip uplink transmission 628. Downlink transmissions may be dynamic or aperiodic, while uplink transmissions may be ongoing periodic transmissions. In other examples, downlink transmissions may be periodic, while uplink transmissions may be dynamic or aperiodic.

[0092] In 612, base station 604 can similarly adjust communication in response to incompatibility between the first beam and the second beam for full-duplex communication. In one aspect, adjusting communication may include adjusting the first beam in response to incompatibility between the first beam and the second beam for full-duplex communication. In another aspect, adjusting communication may include adjusting the second beam for full-duplex communication. In yet another aspect, adjusting communication may include canceling the transmission or reception of one or more periodic transmissions in response to incompatibility between the first beam and the second beam for full-duplex communication. In a further aspect, adjusting communication may include canceling the transmission or reception of a second resource in response to incompatibility between the first beam and the second beam for full-duplex communication.

[0093] Figure 7 Figure 700 illustrates an example aspect of the first and second scheduling information. In some examples, the first scheduling information may relate to ongoing periodic transmissions in half-duplex mode. In one aspect, there may be ongoing uplink configuration-granted (CG) transmissions or uplink feedback transmissions for semi-persistent scheduling (SPS) configuration that are periodically transmitted in half-duplex mode according to the first scheduling information, and the base station may also utilize the second scheduling information to schedule downlink transmissions, such as CORESET, PDSCH, or CSI-RS transmissions. Downlink transmissions may be incompatible with the beams scheduled for ongoing periodic uplink transmissions. For example, if used for full-duplex communication, the use of uplink beams may result in self-interference with reception on the downlink beam. Therefore, in this respect, the first scheduling information that can be associated with the first beam can relate to uplink resources for periodic uplink transmissions using the uplink beam, and the second scheduling information that can be associated with the second beam can relate to downlink resources for receiving downlink transmissions using the downlink beam, which is incompatible with the uplink beam for full-duplex communication.

[0094] On the other hand, there may be ongoing periodic downlink transmissions in half-duplex mode, such as downlink SPS transmissions or downlink feedback transmissions for CG configuration, transmitted according to the first scheduling information. Simultaneously, the base station can utilize the second scheduling information to schedule uplink transmissions, such as PUCCH, PUSCH, or SRS transmissions. The beam used for uplink transmissions may be incompatible with the beam used for pre-existing periodic downlink transmissions. For example, if used for full-duplex communication, the use of the uplink beam can lead to self-interference with reception on the downlink beam. Therefore, in this respect, the first scheduling information, which may be associated with the first beam, may pertain to downlink resources for periodically receiving downlink transmissions using the downlink beam, and the second scheduling information, which may be associated with the second beam, may pertain to uplink resources for uplink transmissions using the uplink beam, which is incompatible with the downlink beam for full-duplex communication.

[0095] Figure 8 This is a flowchart 800 of a wireless communication method. This method can be performed by a UE (e.g., UE 104; UE 602; device 1402). Optionally, aspects are illustrated with dashed lines. This method enables the UE to address potential self-interference that may occur with full-duplex communication based on incompatible beams, such as by combining... Figure 6 The example described is as follows.

[0096] In 802, the UE can receive first scheduling information regarding a first resource used for transmission using the first beam in half-duplex mode. For example, 802 can be... Figure 14 The first scheduling information component 1440 is executed via the receiving component 1430. The transmission can be periodic, or it can be dynamic or aperiodic. The first scheduling information can be used for one or more uplink transmissions. The first scheduling information can provide permission for periodic uplink transmissions (such as CG or uplink feedback associated with SPS transmissions). The first scheduling information can be used for receiving one or more downlink transmissions. The first scheduling information can be used for receiving periodic downlink transmissions (such as SPS transmissions or downlink feedback for CG transmissions).

[0097] At 804, the UE can receive second scheduling information regarding a second resource associated with a second beam that is incompatible with the first beam for full-duplex communication including time-overlapping downlink reception and uplink transmission. For example, the first beam may be selected for half-duplex mode based on a first metric (e.g., RSRP), and the second beam may be selected for full-duplex mode based on a second metric (e.g., SINR or SIM), wherein the second beam is selected to be paired with a third beam for full-duplex mode. The second metric may include self-interference metrics not included in the first metric. The second beam may be incompatible with the first beam based on self-interference between overlapping full-duplex communication on the first and second beams as a pair for full-duplex mode. For example, uplink transmissions on either the first or second beam may cause a threshold level of self-interference to downlink reception on the other beam in full-duplex mode. For example, 804 may be... Figure 14 The second scheduling information component 1442 is executed via the receiving component 1430. The second scheduling information can be used for receiving downlink transmissions (such as CORESET, PDSCH, and / or CSI-RS). The second scheduling information can be used for uplink transmissions, such as for PUCCH, PUSCH, and / or SRS.

[0098] In 806, the UE can adjust communication in response to incompatibility between the first beam and the second beam for full-duplex communication. For example, 806 can be... Figure 14 The communication adjustment component 1444 performs this. For example, in 806, the UE can base its communication adjustment on... Figure 6 610 describes any aspect of adjusting communication.

[0099] In one aspect, adjusting communication at 806 may include resetting the first beam used for transmission or reception of the first resource in response to incompatibility between the first beam and the second beam for full-duplex communication at 806a. Specifically, the UE may use a paired beam instead of the first beam indicated in the first scheduling information to transmit or receive periodic transmissions. The paired beam may include the second beam but not the first beam. As described above, in different aspects, the first beam may correspond to an uplink beam that performs existing periodic uplink transmissions on uplink resources, or to a downlink beam that performs existing periodic downlink transmissions on downlink resources. In the case where the first beam corresponds to an uplink beam, the second beam may correspond to a downlink beam; and in the case where the first beam corresponds to a downlink beam, the second beam may correspond to an uplink beam. In the case where the second beam corresponds to a downlink beam, for full-duplex communication, the paired beam may include the second beam and an uplink beam that is not the first beam, and vice versa. Figures 9A-9D The flowchart 900A-D shows the method of adjusting the first beam according to different aspects.

[0100] In one aspect, the base station can indicate the beam pair (one uplink beam and one downlink beam) used for full-duplex communication in the TCI status field of the second scheduling information. It should be understood that the TCI status can define the quasi-co-location (QCL) assumption between the source RS and the target RS. (See reference...) Figure 9A At 902, the UE may receive an indication of a full-duplex beam pair including a paired beam paired with the second beam in the Transmission Configuration Indicator (TCI) status field of the second scheduling information. At 904, the UE may use the paired beam indicated in the second scheduling information instead of the first beam indicated in the first scheduling information to transmit or receive one or more transmissions.

[0101] On the other hand, the UE can obtain beam pair information in the reference signal configuration used for beam fault detection or radio link management. If the second beam is a downlink beam, the beam indicated in the Interference Measurement Resource (IMR) Reference Signal (RS) configuration can be paired with the second beam for full-duplex communication. On the other hand, if the second beam is an uplink beam, the beam indicated in the Channel Measurement Resource (CMR) Reference Signal (RS) configuration can be paired with the second beam for full-duplex communication. It should be understood that the IMR can be a CSI-RS or a CSI Interference Measurement (CSI-IM) resource, and the CMR can be a CSI-RS resource. (Reference) Figure 9B At 906, the UE can receive a reference signal configuration for beam fault detection or radio link management, indicating the paired beam to be paired with the second beam. At 908, the UE can use the paired beam instead of the first beam indicated in the first scheduling information to transmit or receive one or more transmissions.

[0102] On the other hand, the UE can obtain beam pair information based on the latest Self-Interference Measurement (SIM) or Beam Management (BM) measurement reports. The best candidate beam determined based on the latest SIM or BM measurement report can be paired with a second beam for full-duplex communication. (Reference) Figure 9C In step 910, the UE can perform self-interference measurement (SIM) or beam management (BM) measurement. In step 912, the UE can determine the beam paired with the second beam for full-duplex communication based on the SIM or BM measurement. In step 914, the UE can use the paired beam, rather than the first beam indicated in the first scheduling information, to transmit or receive one or more transmissions.

[0103] On the other hand, there may be opportunities for Random Access Channel (RACH) overlap with the downlink synchronization signal block (SSB). If the second beam is a downlink beam, the beam associated with the transmitted RACH preamble can be paired with the second beam for full-duplex communication. On the other hand, if the second beam is an uplink beam, the beam associated with the transmitted SSB can be paired with the second beam for full-duplex communication. (Reference) Figure 9D In 916, the UE can identify the beam paired with the second beam for full-duplex communication based on the downlink synchronization signal block (SSB) that overlaps with the timing of the random access channel (RACH) in full-duplex mode. In 918, the UE can use the paired beam, rather than the first beam indicated in the first scheduling information, to transmit or receive one or more transmissions.

[0104] On the other hand, adjusting communication in 806 may include resetting the second beam used for transmission or reception of the second resource in 806b. Specifically, the UE may transmit or receive communication based on the second scheduling information using the paired beam indicated in the first scheduling information but not the second beam indicated in the second scheduling information. The paired beam may include the first beam but not the second beam. As described above, in different aspects, when the first beam corresponds to an uplink beam, the second beam may correspond to a downlink beam, or when the first beam corresponds to a downlink beam, the second beam may correspond to an uplink beam. In the case where the first beam corresponds to an uplink beam, for full-duplex communication, the paired beam may include the first beam and a downlink beam that is not the second beam, and vice versa. Figure 10A-10D The flowchart 1000A-D shows the method of adjusting the second beam according to different aspects.

[0105] In one aspect, the base station may indicate the beam pair (one uplink beam and one downlink beam) for full-duplex communication in the Transmission Configuration Indicator (TCI) status field of the first scheduling information. It should be understood that the TCI status may define the quasi-co-location (QCL) assumption between the source reference signal (RS) and the target RS. (Reference) Figure 10A At 1002, the UE can receive an indication of a full-duplex beam pair, including a paired beam paired with the first beam, in the Transmission Configuration Indicator (TCI) status field of the first scheduling information. At 1004, the UE can transmit or receive communications based on the second scheduling information using the paired beam indicated in the first scheduling information instead of the second beam indicated in the second scheduling information.

[0106] On the other hand, the UE can obtain beam pair information in the reference signal configuration used for beam fault detection or radio link management. If the first beam is an uplink beam, the beam indicated in the Channel Measurement Resource (CMR) Reference Signal (RS) configuration can be paired with the first beam for full-duplex communication. On the other hand, if the first beam is a downlink beam, the beam indicated in the Interference Measurement Resource (IMR) Reference Signal (RS) configuration can be paired with the second beam for full-duplex communication. It should be understood that the IMR can be a CSI-RS or CSI Interference Measurement (CSI-IM) resource, and the CMR can be a CSI-RS resource. (Reference) Figure 10B At 1006, the UE can receive a reference signal configuration for beam fault detection or radio link management, which indicates the paired beam matched with the first beam. At 1008, the UE can use the paired beam indicated in the first scheduling information, rather than the second beam indicated in the second scheduling information, to transmit or receive communications based on the second scheduling information.

[0107] On the other hand, the UE can obtain beam pair information based on the latest Self-Interference Measurement (SIM) or Beam Management (BM) measurement reports. The best candidate beam determined based on the latest SIM or BM measurement report can be paired with the first beam for full-duplex communication. (Reference) Figure 10C At 1010, the UE can perform self-interference measurement (SIM) or beam management (BM) measurement. At 1012, the UE can determine the beam paired with the first beam for full-duplex communication based on the SIM or BM measurement. At 1014, the UE can transmit or receive communication based on the second scheduling information using the paired beam indicated in the first scheduling information instead of the second beam indicated in the second scheduling information.

[0108] On the other hand, there may be opportunities for a Random Access Channel (RACH) to overlap with a downlink synchronization signal block (SSB). If the first beam is an uplink beam, the beam associated with the transmitting SSB can be paired with the first beam for full-duplex communication. On the other hand, if the first beam is a downlink beam, the beam associated with the transmitting RACH preamble can be paired with the first beam for full-duplex communication. (Reference) Figure 10D In step 1016, the UE can identify the beam paired with the first beam for full-duplex communication based on the downlink synchronization signal block (SSB) that overlaps with the timing of the random access channel (RACH) in full-duplex mode. In step 1018, the UE can use the paired downlink beam indicated in the first scheduling information, rather than the second beam indicated in the second scheduling information, to transmit or receive communication based on the second scheduling information.

[0109] In another aspect, adjusting communication at 806 may include, at 806c, canceling the transmission or reception of one or more transmissions based on the first resource in response to incompatibility between the first beam and the second beam for full-duplex communication. In a further aspect, adjusting communication at 806 may include, at 806d, canceling the transmission or reception of the second resource in response to incompatibility between the first beam and the second beam for full-duplex communication.

The first scheduling information can be used for the reception of one or more downlink transmissions. The first scheduling information can be used for the reception of periodic downlink transmissions (such as SPS transmissions or downlink feedback for CG transmissions).

[0112] At 1104, the base station may transmit second scheduling information regarding a second resource associated with a second beam that is incompatible with the first beam for full-duplex communication including time-overlapping downlink transmissions and uplink receptions. For example, the first beam may be selected based on a first metric (e.g., RSRP) for half-duplex mode, and the second beam may be selected based on a second metric (e.g., SINR or SIM) for full-duplex mode, wherein the second beam is selected to be paired with a third beam for full-duplex mode. The second metric may include self-interference metrics not included in the first metric. The second beam may be incompatible with the first beam based on self-interference between overlapping full-duplex communication on the first and second beams as a pair for full-duplex mode. For example, uplink transmissions on either the first or second beam may cause a threshold level of self-interference to downlink reception on the other beam in full-duplex mode. The second scheduling information may be used for reception of downlink transmissions such as CORESET, PDSCH, and / or CSI-RS.

Figure 15 The communication adjustment component 1544 performs this. For example, in 1106, the base station can be based on... Figure 6 Section 612 describes any aspect for adjusting communication.

[0114] In one aspect, adjusting communication at 1106 may include adjusting the first beam at 1106a in response to incompatibility between the first beam and the second beam for full-duplex communication. Specifically, the base station may use a paired beam, rather than the first beam indicated in the first scheduling information, to transmit or receive periodic transmissions. The paired beam may include the second beam, but not the first beam. As described above, in different aspects, the first beam may correspond to an uplink beam that performs existing periodic uplink transmissions on uplink resources, or to a downlink beam that performs existing periodic downlink transmissions on downlink resources. In the case where the first beam corresponds to an uplink beam, the second beam may correspond to a downlink beam; and in the case where the first beam corresponds to a downlink beam, the second beam may correspond to an uplink beam. In the case where the second beam corresponds to a downlink beam, for full-duplex communication, the paired beam may include the second beam and an uplink beam that is not the first beam, and vice versa. Figure 12A-12D The flowchart 1200A-D shows the method of adjusting the first beam according to different aspects.

[0115] In one aspect, the base station can indicate the beam pair (one uplink beam and one downlink beam) for full-duplex communication in the Transmission Configuration Indicator (TCI) status field of the second scheduling information. It should be understood that the TCI status can define the quasi-co-location (QCL) assumption between the source reference signal (RS) and the target RS. (Reference) Figure 12A At 1202, the base station may transmit an indication of a full-duplex beam pair, including a paired beam paired with the second beam, in the Transmission Configuration Indicator (TCI) status field of the second scheduling information. At 1204, the base station may use the paired beam indicated in the second scheduling information instead of the first beam indicated in the first scheduling information to transmit or receive one or more transmissions.

[0116] On the other hand, the UE can obtain beam pair information in the reference signal configuration used for beam fault detection or radio link management. If the second beam is a downlink beam, the beam indicated in the Interference Measurement Resource (IMR) Reference Signal (RS) configuration can be paired with the second beam for full-duplex communication. On the other hand, if the second beam is an uplink beam, the beam indicated in the Channel Measurement Resource (CMR) Reference Signal (RS) configuration can be paired with the second beam for full-duplex communication. It should be understood that the IMR can be a CSI-RS or a CSI Interference Measurement (CSI-IM) resource, and the CMR can be a CSI-RS resource. (Reference) Figure 12B At 1206, the base station may transmit a reference signal configuration for beam fault detection or radio link management, indicating the paired beam to be paired with the second beam. At 1208, the base station may use the paired beam, rather than the first beam indicated in the first scheduling information, to transmit or receive one or more transmissions.

[0117] On the other hand, the UE can obtain beam pair information based on the latest Self-Interference Measurement (SIM) or Beam Management (BM) measurement reports. The best candidate beam determined based on the latest SIM or BM measurement report can be paired with a second beam for full-duplex communication. (Reference) Figure 12C In 1210, the base station can receive an indication of a beam paired with the second beam for full-duplex communication. The paired beam can be determined based on self-interference measurement (SIM) or beam management (BM) measurements at the user equipment (UE). In 1212, the base station can use the paired beam, rather than the first beam indicated in the first scheduling information, to transmit or receive one or more transmissions.

[0118] On the other hand, there may be opportunities for Random Access Channel (RACH) overlap with the downlink synchronization signal block (SSB). If the second beam is a downlink beam, the beam associated with the transmitted RACH preamble can be paired with the second beam for full-duplex communication. On the other hand, if the second beam is an uplink beam, the beam associated with the transmitted SSB can be paired with the second beam for full-duplex communication. (Reference) Figure 12D In 1214, the UE can receive an indication of a beam paired with the second beam for full-duplex communication. The paired beam can be identified at the user equipment (UE) based on the downlink synchronization signal block (SSB) overlapping with the random access channel (RACH) timing in full-duplex mode. In 1216, the base station can use the paired beam, rather than the first beam indicated in the first scheduling information, to transmit or receive one or more transmissions.

[0119] On the other hand, adjusting communication at 1106 may include adjusting the second beam at 1106b for full-duplex communication. Specifically, the base station may use the paired beam indicated in the first scheduling information, rather than the second beam indicated in the second scheduling information, to transmit or receive communication based on the second scheduling information. The paired beam may include the first beam but not the second beam. As described above, in different aspects, when the first beam corresponds to an uplink beam, the second beam may correspond to a downlink beam, or when the first beam corresponds to a downlink beam, the second beam may correspond to an uplink beam. In the case where the first beam corresponds to an uplink beam, for full-duplex communication, the paired beam may include the first beam and a downlink beam that is not the second beam, and vice versa. Figures 13A-13D The flowchart 1300A-D shows the method of adjusting the second beam according to different aspects.

[0120] In one aspect, the base station may indicate the beam pair (one uplink beam and one downlink beam) for full-duplex communication in the Transmission Configuration Indicator (TCI) status field of the first scheduling information. It should be understood that the TCI status may define the quasi-co-location (QCL) assumption between the source reference signal (RS) and the target RS. (Reference) Figure 13A At 1302, the base station may transmit an indication of a full-duplex beam pair, including a paired beam paired with the first beam, in the Transmission Configuration Indicator (TCI) status field of the first scheduling information. At 1304, the base station may use the paired beam indicated in the first scheduling information, rather than the second beam indicated in the second scheduling information, to transmit or receive communications based on the second scheduling information.

[0121] On the other hand, the UE can obtain beam pair information in the reference signal configuration used for beam fault detection or radio link management.

(Reference) Figure 13B At 1306, the base station can transmit a reference signal configuration for beam fault detection or radio link management, indicating the paired beam to which the first beam is paired. At 1308, the base station can transmit or receive communications based on the second scheduling information using the paired beam indicated in the first scheduling information instead of the second beam indicated in the second scheduling information.

[0122] On the other hand, the UE can obtain beam pair information based on the latest Self-Interference Measurement (SIM) or Beam Management (BM) measurement reports. The best candidate beam determined based on the latest SIM or BM measurement report can be paired with the first beam for full-duplex communication. (Reference) Figure 13C In 1310, the base station can receive an indication of a beam paired with the first beam for full-duplex communication. The paired beam can be determined based on self-interference measurement (SIM) or beam management (BM) measurements at the user equipment (UE). In 1312, the base station can use the paired beam indicated in the first scheduling information, rather than the second beam indicated in the second scheduling information, to transmit or receive communication based on the second scheduling information.

[0123] On the other hand, there may be opportunities for a Random Access Channel (RACH) to overlap with a downlink synchronization signal block (SSB). If the first beam is an uplink beam, the beam associated with the transmitting SSB can be paired with the first beam for full-duplex communication. On the other hand, if the first beam is a downlink beam, the beam associated with the transmitting RACH preamble can be paired with the first beam for full-duplex communication.

[0124] In another aspect, adjusting communication at 1106 may include canceling the transmission or reception of one or more periodic transmissions in 1106c in response to incompatibility between the first beam and the second beam for full-duplex communication. In a further aspect, adjusting communication at 1106 may include canceling the transmission or reception of a second resource in response to incompatibility between the first beam and the second beam for full-duplex communication.

[0125] Figure 14 Figure 1400 illustrates an example of the hardware implementation of device 1402. Device 1402 is a UE and includes a cellular baseband processor 1404 (also referred to as a modem) coupled to a cellular RF transceiver 1422 and one or more Subscriber Identity Module (SIM) cards 1420, an application processor 1406 coupled to a Secure Digital Card (SD) card 1408 and a screen 1410, a Bluetooth module 1412, a Wireless Local Area Network (WLAN) module 1414, a Global Positioning System (GPS) module 1416, and a power supply 1418. The cellular baseband processor 1404 communicates with UE 104 and / or BS 102 / 180 via the cellular RF transceiver 1422. The cellular baseband processor 1404 may include computer-readable media / memory. The computer-readable media / memory may be non-transient. The cellular baseband processor 1404 is responsible for general processing, including the execution of software stored on the computer-readable media / memory. When executed by the cellular baseband processor 1404, the software causes the cellular baseband processor 1404 to perform the various functions described above.
