Techniques for configuring downlink control information for multi-beam full-duplex operation

Abstract

Aspects of the disclosure provide techniques for configuring a device (e.g., a user equipment (UE) or a base station) to perform multi-beam full-duplex communication that allows the device to contemporaneously perform both uplink and downlink communication on the same frequency band. Due to the full-duplex communication capability provided by the disclosure, NR systems can achieve reduced latency and improved spectral and resource efficiency, thereby accommodating the ever-increasing demand for wireless communication. The full-duplex communication capability can be achieved by implementing a downlink control information (DCI) format that specifies a beam assignment for contemporaneous transmission (Tx) and reception (Rx) to a UE. In particular, the beams can be selected such that the beam(s) assigned for communication are independent and uncorrelated, and thus provide sufficient beam diversity to mitigate limitations of current systems, including self-interference that has hindered the implementation of full-duplex communication in current systems.

[0003] background

[0004] This disclosure relates to wireless communication systems, and more particularly to techniques for configuring downlink control information (DCI) for multi-beam full-duplex communication.

[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 (e.g., bandwidth, transmit power). 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, and Single Carrier Frequency Division Multiple Access (SC-FDMA) 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, national, regional, and even global levels. For example, fifth-generation (5G) wireless communication technology (which may be referred to as New Radio (NR)) is designed to expand and support a diverse range of use cases and applications relative to current mobile network generations. In one aspect, 5G communication technologies can include: enhanced mobile broadband for human-centric use cases of accessing multimedia content, services, and data; ultra-reliable low latency communication (URLLC) with certain specifications regarding latency and reliability; and massive machine-type communication, which allows for a very large number of connected devices and the transmission of relatively small amounts of non-latency-sensitive information. However, with the continued growth in demand for mobile broadband access, further improvements to NR and ultra-NR communication technologies may be expected.

[0007] Overview

[0008] This disclosure provides techniques for configuring multi-beam full-duplex communication that allows devices (e.g., user equipment (UE) or base stations) to simultaneously perform both uplink and downlink communication on the same frequency band. Due to the full-duplex communication capabilities provided by this disclosure, NR systems can achieve reduced latency and improved spectrum and resource efficiency, thereby adapting to the ever-increasing demands of wireless communication. Full-duplex communication capability is achieved by implementing a downlink control information (DCI) format that specifies beam assignments to the UE for simultaneous transmission (Tx) and reception (Rx). Specifically, beams can be selected such that the beams assigned for communication are independent and uncorrelated, thus providing sufficient beam diversity to help mitigate limitations of current systems, including self-interference that has hindered full-duplex communication in current systems.

[0009] In one example, a method for wireless communication is disclosed. The method may include receiving, at a first UE, a DCI transmission for facilitating multi-beam full-duplex communication. The method may further include decoding the DCI to identify one or more beams from a plurality of candidate beams for use by the first UE in multi-beam full-duplex communication. Multi-beam full-duplex communication may include the first UE simultaneously transmitting uplink communication on at least a first beam and receiving downlink communication on at least a second beam in the same frequency band. The method may further include transmitting uplink data to a base station or a second UE via a first antenna set of the UE during a first time slot on at least the first beam identified based on the decoded DCI. The method may further include receiving downlink data from the base station or the second UE via a second antenna set of the UE during the first time slot on at least the second beam identified based on the decoded DCI.

The processor may be further configured to execute instructions to decode the DCI to identify one or more beams from a plurality of candidate beams for use by the first UE in multi-beam full-duplex communication. Multi-beam full-duplex communication may include the first UE simultaneously transmitting uplink communication on at least a first beam and receiving downlink communication on at least a second beam in the same frequency band. The processor may be further configured to execute instructions to transmit uplink data to a base station or a second UE via a first antenna set of the UE during a first time slot on at least the first beam identified based on the decoded DCI. The processor may be further configured to execute instructions to receive downlink data from the base station or the second UE via a second antenna set of the UE during a first time slot on at least the second beam identified based on the decoded DCI.

[0011] In some aspects, a non-transient computer-readable medium includes instructions stored therein that, when executed by a processor, cause the processor to perform the step of receiving DCI transmission at a first UE to facilitate multi-beam full-duplex communication. The processor may further execute instructions for: decoding the DCI to identify one or more beams from a plurality of candidate beams for use by the first UE in multi-beam full-duplex communication. Multi-beam full-duplex communication may include the first UE simultaneously transmitting uplink communication on at least a first beam and receiving downlink communication on at least a second beam in the same frequency band. The processor may further execute instructions for: transmitting uplink data to a base station or a second UE via a first antenna set of the UE during a first time slot on at least the first beam identified based on the decoded DCI. The processor may further execute instructions for: receiving downlink data from the base station or the second UE via a second antenna set of the UE during a first time slot on at least the second beam identified based on the decoded DCI.

[0012] In some aspects, another apparatus for wireless communication is disclosed. This apparatus may include means for receiving, at a first UE, DCI transmission to facilitate multi-beam full-duplex communication. The apparatus may further include means for decoding the DCI to identify one or more beams from a plurality of candidate beams for use by the first UE in multi-beam full-duplex communication. Multi-beam full-duplex communication may include the first UE simultaneously transmitting uplink communication on at least a first beam and receiving downlink communication on at least a second beam in the same frequency band. The apparatus may further include means for transmitting uplink data to a base station or a second UE via a first antenna set of the UE during a first time slot on at least the first beam identified based on the decoded DCI. The apparatus may further include means for receiving downlink data from the base station or the second UE via a second antenna set of the UE during the first time slot on at least the second beam identified based on the decoded DCI.

[0013] In another example, a different method for wireless communication is disclosed. The method may include, at a first device, selecting from a plurality of candidate beams one or more beams to be used for multi-beam full-duplex communication by a second device capable of full-duplex communication. The method may further include, at the first device, generating a Directional Interpretation (DCI) to include information identifying the one or more beams selected for multi-beam full-duplex communication by the second device, wherein the multi-beam full-duplex communication allows the second device to simultaneously transmit uplink communication on at least a first beam and receive downlink communication on at least a second beam in the same frequency band based on the DCI generated by the first device. The method may also include transmitting the DCI to the second device to configure for multi-beam full-duplex communication.

[0014] In another example, an apparatus for wireless communication.

The processor may be further configured to execute instructions at the first device to generate a Directional Integrated Communication (DCI) including information identifying the one or more beams selected for multi-beam full-duplex communication by the second device, wherein the multi-beam full-duplex communication allows the second device to simultaneously transmit uplink communication on at least a first beam and receive downlink communication on at least a second beam in the same frequency band based on the DCI generated by the first device. The processor may be further configured to execute instructions to transmit the DCI to the second device for configuration for multi-beam full-duplex communication.

[0015] In some aspects, a non-transient computer-readable medium includes instructions stored therein that, when executed by a processor, cause the processor to perform the following steps: at a first device, selecting from a plurality of candidate beams one or more beams for multi-beam full-duplex communication by a second device capable of full-duplex communication. The processor may further execute instructions for: generating a Direct Current Interface (DCI) at the first device to include information identifying the one or more beams selected for multi-beam full-duplex communication by the second device, wherein the multi-beam full-duplex communication allows the second device to transmit uplink communication synchronously on at least a first beam and receive downlink communication on at least a second beam in the same frequency band based on the DCI generated by the first device. The processor may further execute instructions for: transmitting the DCI to the second device to configure for multi-beam full-duplex communication.

[0016] In some aspects, another device for wireless communication is disclosed.

The device may further include means at the first device for generating a Direct Current Interface (DCI) to include information identifying the one or more beams selected for multi-beam full-duplex communication by the second device, wherein the multi-beam full-duplex communication allows the second device to simultaneously transmit uplink communication on at least a first beam and receive downlink communication on at least a second beam in the same frequency band based on the DCI generated by the first device. The device may also include means for transmitting the DCI to the second device to configure for multi-beam full-duplex communication.

[0027] Detailed description

[0028] In recent years, with the launch of numerous smart handheld devices, user demand for mobile broadband has increased dramatically. For example, the rapid growth of bandwidth-intensive applications such as video streaming and multimedia file sharing is putting immense pressure on the limits of current cellular systems. To address this growing demand, one aspect of 5G NR communication technology involves using high-frequency bands above 24 GHz, often referred to as millimeter-wave (mmW) bands. These bands offer significantly higher data rates and data processing capabilities compared to existing wireless systems such as LTE and 3G. However, the mmW band is susceptible to rapid channel changes and suffers from free-space path loss and atmospheric absorption. Furthermore, the mmW band is highly susceptible to congestion (e.g., penetration by hands, heads, bodies, leaves, and buildings). Especially at mmW frequencies, even minor environmental changes, such as head turns, hand movements, or passing cars, can alter the channel conditions between the base station and the user unit (UE), thus affecting communication performance.

[0029] Current mmW 5G NR systems utilize small wavelengths at higher frequencies in mmW to create highly directional beams using multiple-input multiple-output (MIMO) antenna arrays. These highly directional beams focus the transmitted radio frequency (RF) energy in an attempt to overcome propagation and path loss challenges in both the uplink and downlink. Even so, such systems use half-duplex communication, which utilizes time-division and / or frequency-division for bidirectional communication. However, current systems have so far been unable to achieve full-duplex communication practically due to limitations such as self-interference that can arise from attempts to transmit and receive communications simultaneously on the same frequency band. Generally, self-interference at a device (e.g., a base station or UE) can originate from signal leakage transmitted on the device's first antenna set to the receiver port used for the second antenna set. Additionally, other limitations to achieving theoretical full-duplex gain include, but are not limited to, residual self-interference, traffic constraints, and inter-cell and intra-cell interference.

[0030] The aspects of this disclosure address the aforementioned problems by providing techniques for configuring multi-beam full-duplex communication that allows devices (e.g., UEs or base stations) to simultaneously perform uplink and downlink communication on the same frequency band. Multi-beam full-duplex communication can refer to a situation where a UE can receive downlink communication from a first base station on a first mmW beam set, while simultaneously transmitting uplink traffic to a second base station on a second mmW beam set. In other cases, multi-beam full-duplex communication may include a base station transmitting downlink traffic to a first UE on a first mmW beam set, while simultaneously receiving uplink traffic from a second UE on a second mmW beam set. Additionally, an example of multi-beam full-duplex communication may be a UE transmitting uplink traffic to a base station on a first mmW beam set, while simultaneously receiving downlink traffic from a base station on a second mmW beam set in the same frequency band (or symbol / time slot).

[0031] Full-duplex communication capability can be achieved by implementing a DCI format that specifies beam assignments to the UE for concurrent Tx and Rx communications. For example, beams for uplink and downlink communications can be selected such that the beams(s) assigned to each communication are independent and uncorrelated, thus providing sufficient beam diversity to mitigate (e.g., reduce) current system limitations, including self-interference. The DCI also determines whether the device can be configured for full-duplex capability. In full-duplex operation, it may be required that the DCI format be specified to support various multi-beam full-duplex operations. Therefore, in some aspects, the techniques of this disclosure provide the benefit of including multiple DCI formats for implementing multi-beam full-duplex operation.

[0032] To determine whether a device is capable of performing full-duplex communication (and whether full-duplex communication can be enabled), the wireless device may perform a self-interference measurement (SIM). For example, the wireless device (e.g., a UE) may transmit signals from a first antenna set in one or more Tx beam directions and measure the signals received (already Rxed) from reflected or leaked signals from the Tx signals in one or more Rx beam directions on a second antenna set. In some respects, the first and second antenna sets may be the same or different. Based on the SIM performed by the wireless device, the base station (or a second UE in sidelink communication) may assign one or more Tx and Rx beams that the UE can use for concurrent uplink and downlink full-duplex communication.

[0033] The assignment of Tx and Rx beams (or uplink and downlink beams) from multiple candidate beams can be signaled to the UE via DCI from the base station or another UE (in the case of sidelink communication). For example, each uplink and downlink beam can be indicated by a separate downlink or uplink via a Transmission Configuration Indication (TCI) status identifier (ID). The selection of multiple TCIs or beams is referred to as multi-TCI or multi-beam operation, and this type of operation can be used to improve reliability because the use of multiple TCIs or beams improves stability and resilience against congestion. In some aspects, TCI status can be used to cluster one or more mmW beams based on correlation information to ensure reliability and stability in multi-TCI or multi-beam operation.

[0034] In other examples, the assignment of Tx and Rx beams from multiple candidate beams can be signaled to the UE via a single TCI code point included in the DCI. Specifically, a combination of downlink TCI states and uplink TCI states can be mapped to a single TCI code point transmitted to the UE in the DCI. Based on the TCI code point information included in the DCI, the UE can decode the DCI and identify one or more Tx and Rx beams from multiple candidate beams to be used for multi-beam full-duplex communication by the UE. Additionally or alternatively, downlink TCI states can be mapped to a single downlink TCI code point, while uplink TCI states can be mapped separately to a single uplink TCI code point. Both downlink and uplink TCI code point information can be signaled to the UE in the DCI. Based on the decoding of the DCI and the corresponding uplink and downlink TCI code points, the UE can determine one or more Tx and Rx beams to be used for multi-beam full-duplex communication.

[0035] In some examples, the base station (or a second UE for sidelink communication) may utilize the DCI for cross-carrier scheduling of multi-beam full-duplex communication. For example, the DCI may schedule transmissions on multiple component carriers (CCs), where the scheduling DCI originates from a first CC (e.g., Pcell), and communication may be scheduled on a second CC (e.g., Scell) for downlink communication, uplink communication, or concurrent downlink and uplink multi-beam full-duplex communication. Instructions for beam assignment for multi-beam full-duplex communication may be communicated to the UE via one or more techniques identified by the DCI (e.g., each downlink / uplink beam is identified by a TCI state ID, a single TCI code point, or separate uplink and downlink TCI code points).

[0036] In some aspects, semi-persistent scheduling (SPS) and configured permission (CG) can be activated and deactivated based on a DCI identifying a specific Tx and Rx beam to be used for multi-beam full-duplex communication. In some examples, at least one SPS and CG configuration may have the same period, which has transmission opportunities that partially / completely overlap at least in time and / or frequency. A DCI can also be activated or deactivated for cross-carrier SPS by simultaneously scheduling an SPS for a second CC and transmitting the DCI on the first CC.

[0037] Additionally or alternatively, the DCI may include scheduling information associated with time-division multiplexing (via TDM) repetition of traffic that is repeatedly transmitted on multiple transmission occasions. In some instances, TDM repetition may span multiple time slots or mini-time slots. Each repetition on multiple time slots (or mini-time slots) may include scheduling of downlink traffic, uplink traffic, or simultaneous downlink and uplink full-duplex communication, which may be the same or different across repetitions. In some instances, a single DCI may indicate the downlink beam, uplink beam(s), or simultaneous downlink and uplink beam(s) for each repetition transmission. Indications for beam assignment for multi-beam full-duplex communication may also be signaled to the UE via one or more of the techniques described above for DCI identification (e.g., each downlink / uplink beam is identified by a TCI status ID, a single TCI code point, or separate uplink and downlink TCI code points).

[0038] In some instances, the UE may be in sleep mode. Therefore, the base station and / or a second UE can transmit a wake-up signal (WUS) to transition the UE from sleep mode to active mode. In some examples, a DCI associated with multi-beam full-duplex communication may be included in the WUS and indicate whether the subsequent discontinuous reception (DRX) activation duration will be used for downlink communication, uplink communication, or full-duplex uplink and downlink simultaneous communication. The DCI included in the WUS can also be used to identify one or more Tx and / or Rx beams from multiple candidate beams for subsequent DRX activation duration for full-duplex uplink and downlink simultaneous communication based on decoding the DCI.

[0039] Additionally or alternatively, aspects of this disclosure also provide techniques for enabling multi-beam full-duplex communication for sidelink communication between multiple UEs (e.g., a first UE and a second UE) that does not involve a base station. In such instances, the DCI can schedule full-duplex communication between two UEs in a sidelink via a two-stage DCI. In one example, during the first-stage DCI, only one of the two UEs in the sidelink communication may transmit a "Stage 1" DCI with preliminary scheduling information to schedule full-duplex transmission of the Physical Sidelink Shared Channel (PSSCH) in both directions (e.g., uplink and downlink) for a subsequent second stage ("Stage 2"). Thus, during the second stage, each of the two UEs in the sidelink communication may transmit a Stage 2 DCI in the PSSCH to provide the remaining (or complete) scheduling information for the UE to decode the data in the PSSCH.

[0040] In other examples of sidelink communication, each UE may transmit a Phase 1 DCI with preliminary scheduling information to schedule the PSSCH desired in the second phase from that UE. In some examples, the first and second Phase 1 DCIs transmitted from the first UE to each other may be transmitted using full-duplex communication in TDM or simultaneously. In each instance, the preliminary scheduling information included in the Phase 1 DCI may include PSSCH time / frequency resource assignment, modulation and coding scheme (MCS), MNRS mode or port number, β offset, priority, or Phase 2 DCI format. Additionally, the remaining scheduling information transmitted during the second phase may include PSSCH Hybrid Automatic Repeat Request (HARQ) ID, New Data Indicator (NDI), RV, Channel State Information (CSI) request, or source / destination node ID.

[0041] In some aspects, the DCI in the PSCCH used for sidelink communication can also be transmitted simultaneously from two UEs. In this example, a search space can exist between the two UEs to decode the DCI. To this end, in some examples, two separate search spaces can be configured for the two UEs to transmit their respective PSCCHs simultaneously, and each search space can have its own CORESET configuration (e.g., time / frequency allocation, beam and search space configuration, such as aggregation level, number of candidate DCIs per aggregation level, etc.). In other examples, a single search space can be configured for the two UEs to transmit their respective PSCCHs simultaneously. In this example, the joint search space can have CORESET and search space configurations for each of the two directions (e.g., uplink and downlink).

[0042] Now refer to Figure 1-4 The various aspects are described in more detail below. Numerous specific details are set forth for illustrative purposes to provide a thorough understanding of one or more aspects. However, it is obvious that such aspects can be practiced without these specific details. Furthermore, as used herein, the term "component" can refer to one of the parts that make up a system, can be hardware, firmware, and / or software stored on a computer-readable medium, and can be divided into other components.

[0043] The following description provides examples and is not intended to limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this disclosure. Various procedures or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with reference to some examples may be combined in other examples.

[0044] Figure 1This is an illustration of an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a wireless wide area network (WWAN)) may include base station 102, UE 104, evolved packet core (EPC) 160, and / or 5G core (5GC) 190. Base station 102 may include macrocells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macrocells may include base stations. Small cells may include femtocells, picocells, and microcells. In one example, base station 102 may also include gNB 180, as further described herein. In one example, some nodes in the wireless communication system may have modems and full-duplex communication management components 350 for facilitating multi-beam full-duplex communication according to aspects described herein. And although the figures show UE 104 implementing full-duplex communication component 350, it should be understood that full-duplex capability (or alternatively, flexible time-division duplex (TDD) capability) may be provided by one or more UEs 104 and / or gNB 180 (see example...). Figure 5 This is achieved through the DCI generation component 550 in the document. Therefore, while this is an illustrative example, virtually any node or any type of node may include a modem and full-duplex communication component 350 to provide the corresponding functionality described herein.

[0045] Base station 102 configured for 4G LTE (which may be collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via backhaul link 132 (e.g., using the S1 interface). Base station 102 configured for 5G NR (which may be collectively referred to as Next Generation RAN (NG-RAN)) can interface with 5GC 190 via backhaul link 184. Among other functions, base station 102 may 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 stations 102 can communicate directly or indirectly (e.g., via EPC 160 or 5GC 190) on backhaul link 134 (e.g., using an X2 interface). Backhaul link 134 can be wired or wireless.

[0046] Base station 102 can wirelessly communicate with one or more UEs 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, a small cell 102' may have a coverage area 110' that overlaps 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), which can provide services to a restricted group (which may be referred to as a Closed Subscriber Group (CSG)). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also referred to as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also referred to 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 (e.g., for x component carriers) used for transmission in the DL and / or UL directions, 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. Carrier allocation 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 carriers may be referred to as secondary cells (SCells).

[0047] In another example, some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The 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, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0048] 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 in the 5 GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) before communication to determine whether the channel is available.

[0049] 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 5 GHz unlicensed spectrum as that 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.

[0050] Whether it's a small cell 102' or a large cell (e.g., a macro base station), base station 102 may include an eNB, a gB node (gNB), or other types of base stations. Some base stations (such as gNB 180) may operate in conventional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near-mmW frequencies to communicate with UE 104. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 may be referred to as an mmW base station. Extremely high frequency (EHF) is a portion of the electromagnetic spectrum that contains radio frequency (RF). EHF has a range from 30 GHz to 300 GHz and wavelengths between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near-mmW extends down to 3 GHz frequencies with a wavelength of 100 mm. Ultra-high frequency (SHF) bands extend between 3 GHz and 30 GHz, and are also referred to as centimeter waves. Communication using mmW / near-mmW RF bands has extremely high path loss and short range. mmW base station 180 can utilize beamforming 182 with UE 104 to compensate for extremely high path loss and short range. Base station 102 as referred to herein may include gNB 180.

[0051] 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.

The BM-SC170 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.

[0054] In one example, the full-duplex communication component 350 may receive a DCI transmission to facilitate multi-beam full-duplex communication. The full-duplex communication component 350 may also decode the DCI to identify one or more beams from a plurality of candidate beams for use by the first UE in multi-beam full-duplex communication. In some examples, multi-beam full-duplex communication may include the first UE simultaneously transmitting uplink communication on at least a first beam and receiving downlink communication on at least a second beam in the same frequency band. Furthermore, the full-duplex communication component 350 may transmit uplink data to a base station or a second UE via a first antenna set of the UE during a first time slot on at least the first beam identified based on the decoded DCI. The full-duplex communication component 350 may also receive downlink data from the base station or the second UE via a second antenna set of the UE during the first time slot on at least the second beam identified based on the decoded DCI.

[0055] Similarly, one or more base stations (e.g., gNB 102) or UE 104 (e.g., for sidelink communication) may generate DCI according to various aspects of this disclosure and signal on the same frequency band to notify full-duplex capability and beam assignment for concurrent uplink and downlink communication.

[0056] Figure 2A-2D Schematic diagrams illustrating various use cases of multi-beam full-duplex communication according to aspects of this disclosure are provided. In particular, aspects of this disclosure provide techniques for configuring multi-beam full-duplex communication that allows devices (e.g., UE 104 or gNB 102) to simultaneously perform uplink and downlink communication on the same frequency band.

[0057] As discussed above, multi-beam full-duplex communication can refer to... Figure 2A The following scenario is explained: UE104 can receive downlink communication 205 from the first base station 102-a on the first mmW beamset 210, and simultaneously transmit uplink traffic 215 to the second base station 102-b on the second mmW beamset 220. In other scenarios, such as... Figure 2B As explained in the text, multi-beam full-duplex communication may include base station 102-a transmitting downlink traffic 230 to first UE 104-a on a first mmW beam set 235, while simultaneously receiving uplink traffic 240 from second UE 104-b on a second mmW beam set 245. Additionally, as in... Figure 2C As explained, an example of multi-beam full-duplex communication could be that UE 104 transmits uplink traffic 255 to base station 102 on the first mmW beam set 260, while simultaneously receiving downlink traffic 265 from base station 102 on the second mmW beam set 270 in the same frequency band (or symbol / time slot). Multi-beam full-duplex communication may also include sidelink communication, such as... Figure 2DAs explained in the text, the first UE 104-a can transmit uplink traffic 275 to the second UE 104-b on the first mmW beam set 280, while simultaneously receiving downlink traffic 290 from the second UE 104-b on the second mmW beam set 295.

[0058] In each of these instances, full-duplex capability and beam assignment can be signaled to the UE (e.g., the first UE 104-a) via DCI transmitted from base station 102 or another UE (e.g., the second UE 104-b in a sidelink communication scenario). For example, each downlink and uplink beam (e.g., Figure 2A The first mmW beamset 210 for downlink communication and the second mmW beamset 220 for uplink communication can be indicated by a TCI status ID for a separate downlink or uplink. In some respects, the TCI status can cluster one or more mmW beams based on correlation information to ensure reliability and stability in multi-TCI or multi-beam operation.

[0059] In other examples, the assignment of Tx and Rx beams from multiple candidate beams can be signaled to UE 104 via a single TCI code point included in the DCI. Specifically, a combination of downlink TCI states and uplink TCI states can be mapped to a single TCI code point transmitted to the UE in the DCI. Based on the TCI code point information included in the DCI, UE 104 can decode the DCI and identify one or more Tx and Rx beams from the multiple candidate beams to be used for multi-beam full-duplex communication by UE 104. Additionally or alternatively, downlink TCI states can be mapped to a single downlink TCI code point, while uplink TCI states can be mapped separately to a single uplink TCI code point. The downlink and uplink TCI code point information can be signaled to the UE in the DCI. Based on the decoding of the DCI and the corresponding uplink and downlink TCI code points, the UE can determine one or more Tx and Rx beams to be used for multi-beam full-duplex communication.

[0061] In some aspects, the full-duplex communication component 350 can receive DCI transmissions to facilitate multi-beam full-duplex communication, and decode the DCI via the DCI component 360 to identify one or more beams from a plurality of candidate beams for use by the first UE in multi-beam full-duplex communication, wherein the multi-beam full-duplex communication includes the first UE simultaneously transmitting uplink communication on at least a first beam and receiving downlink communication on at least a second beam in the same frequency band. Furthermore, the full-duplex communication component 350 can transmit uplink data to a base station or a second UE via a first antenna set of the UE during a first time slot on at least a first beam identified based on the decoded DCI. The full-duplex communication component 350 can also receive downlink data from the base station or the second UE via a second antenna set of the UE during a first time slot on at least a second beam identified based on the decoded DCI.

[0066] On one hand, the LNA 390 can amplify the received signal to a desired output level. On another hand, each LNA 390 can have specified minimum and maximum gain values. On yet another hand, the RF front end 388 can use one or more switches 392 to select a particular LNA 390 and its specified gain value based on the desired gain value for a particular application.

[0067] Furthermore, for example, one or more PAs 398 may be used by the RF front end 388 to amplify signals to obtain an RF output with a desired output power level.

In another aspect, the RF front end 388 may use one or more switches 392 to select a particular PA 398 and its specified gain value based on the desired gain value for a particular application.

[0068] Furthermore, for example, one or more filters 396 may be used by the RF front end 388 to filter the received signal to obtain the input RF signal. Similarly, in one aspect, for example, a corresponding filter 396 may be used to filter the output from a corresponding PA 398 to produce an output signal for transmission. In one aspect, each filter 396 may be connected to a specific LNA 390 and / or PA 398.

[0071] Reference Figure 4 Example method 400 for wireless communication according to various aspects of this disclosure can be found by reference. Figure 1 The method 400 is performed by one or more UEs 104 discussed in section 2. Although method 400 is described below with respect to the various elements of UE 104, other components may also be used to implement one or more of the steps described herein.

[0072] At block 405, method 400 may include receiving a DCI transmission at a first UE to facilitate multi-beam full-duplex communication. In some examples, the method may include receiving a DCI transmission at the first UE from a first component carrier to facilitate multi-beam full-duplex communication for the first UE on a second component carrier.

In some examples, the DCI may further identify at least a first beam for uplink communication and at least a second beam for downlink communication, the first UE being configured to use the first and second beams for periodic communication with a base station or a second UE using multi-beam full-duplex communication. The method may also include deactivating at least one SPS configuration and at least one configured-allowed CG for the first UE via the DCI received at the first UE.

[0073] In some aspects, activating at least one SPS configuration for the first UE and the at least one CG may include receiving, at the first UE, a DCI transmission from a first component carrier to facilitate multi-beam full-duplex communication for the first UE on a second component carrier, and activating at least one SPS configuration and at least one configured-enabled CG for the first UE on the second component carrier via the DCI received from the first component carrier.

[0076] In some instances, the UE can be configured with two separate search spaces so that each of the first and second UEs can transmit and receive data simultaneously on the PSSCH. In other instances, the UE can be configured with a single, separate search space so that each of the first and second UEs can transmit and receive data simultaneously on the PSSCH.

[0077] Furthermore, the first antenna set and the second antenna set of the UE can be the same or different. Various aspects of block 405 can be performed by transceiver 302, which receives communications from gNB 102 or another UE 104 via one or more antennas 365, as shown in reference...

In an additional example, decoding the DCI may include identifying a first TCI code point included in the DCI mapped to a downlink TCI state, and identifying a second TCI code point included in the DCI mapped to an uplink TCI state. The method may also include determining one or more beams from a plurality of candidate beams to be used for multi-beam full-duplex communication by the first UE based on the first and second TCI code points.

[0080] In some aspects, decoding the DCI may include determining that the DCI includes information about repeated communications within a plurality of time slots, wherein each of the plurality of time slots is configured for downlink communication, uplink communication, or full-duplex uplink and downlink simultaneous communication. The method may also include identifying from the plurality of candidate beams one or more beams to be used for repeated communication during the plurality of time slots used for downlink communication, uplink communication, or full-duplex uplink and downlink simultaneous communication.

[0081] Additionally or alternatively, decoding the DCI may include receiving a WUS from a base station at a first UE to wake the first UE from a sleep mode, wherein the WUS includes the DCI. The method may include decoding the DCI to determine whether the operation during the subsequent discontinuous reception (DRX) activation duration is for downlink communication, uplink communication, or full-duplex uplink and downlink simultaneous communication, and based on decoding the DCI, identifying one or more beams from a plurality of candidate beams to be used for full-duplex uplink and downlink simultaneous communication during the subsequent DRX activation duration.

Similarly, in one aspect, for example, a corresponding filter 596 may be used to filter the output from a corresponding PA 598 to produce an output signal for transmission. In one aspect, each filter 596 may be connected to a specific LNA 590 and / or PA 598.

[0093] Thus, transceiver 502 can be configured to transmit and receive wireless signals via RF front end 588 through one or more antennas 565. In one aspect, transceiver 502 can be tuned to operate at a specified frequency so that the transmitting device can, for example, communicate with one or more UEs 104 or one or more cells associated with one or more base stations 102. In another aspect, for example, modem 514 can configure transceiver 502 to operate at a specified frequency and power level based on the configuration of the transmitting device and the communication protocol used by modem 514.

In another aspect, modem 514 may be multi-band and configured to support multiple frequency bands for a specific communication protocol. In another aspect, modem 514 may be multi-mode and configured to support multiple operating networks and communication protocols. In one aspect, modem 514 may control one or more components of the transmitting device (e.g., RF front-end 588, transceiver 502) to enable signal transmission and / or reception with the network based on a specified modem configuration. In one aspect, the modem configuration may be based on the mode and frequency band used by modem 514. In another aspect, the modem configuration may be based on UE configuration information associated with the transmitting device, such as information provided by the network during cell selection and / or cell reselection.

Figure 1 This is performed by one or more base stations 102 or UE 104 in the sidelink communication discussed in section 2. Thus, in some examples, the “first device” mentioned herein may be base station 102 or UE 104, and the “second device” may be UE 104. Additionally, although method 600 is described below with respect to the elements of base station 102 or UE 104, other components may also be used to implement one or more of the steps described herein.

[0096] At block 605, method 600 may include, at a first device, selecting from a plurality of candidate beams one or more beams to be used for multi-beam full-duplex communication by a second device capable of full-duplex communication.

Thus, the DCI generation component 550, modem 314, processor 312 and / or UE 104 or one of their sub-components may define means for selecting, at the first device, one or more beams from a plurality of candidate beams for use in multi-beam full-duplex communication by a second device capable of full-duplex communication.

[0097] In block 610, method 600 may include generating downlink control information (DCI) at a first device to include information identifying one or more beams selected for multi-beam full-duplex communication by a second device, wherein the multi-beam full-duplex communication allows the second device to transmit uplink communication simultaneously on at least a first beam and receive downlink communication on at least a second beam in the same frequency band based on the DCI generated by the first device. In some examples, the DCI includes a TCI state ID within the DCI. The TCI state ID may indicate that the first UE is configured to use each uplink and downlink beam for multi-beam full-duplex communication with a base station or the second UE.

[0098] In some examples, generating the DCI to include information identifying one or more beams selected for multi-beam full-duplex communication for the second device may include mapping one or both of a downlink TCI state and an uplink TCI state to a TCI code point, and attaching the TCI code point to the DCI, wherein the TCI code point identifies at least a first beam for uplink communication and at least a second beam for downlink communication for the second device to use for multi-beam full-duplex communication.

[0100] Additionally or alternatively, the DCI may further include information about repeated communications within multiple time slots. In such instances, each time slot within the multiple time slots may be configured for downlink communication, uplink communication, or full-duplex uplink and downlink simultaneous communication. Aspects of block 615 may be referenced from... Figure 5 The described DCI generation component 550 and modem 514 are used to perform this. Thus, the DCI generation component 550, modem 314, processor 312, and / or UE 104 or any of their sub-components can be defined to generate downlink control information (DCI) at the first device to include information identifying one or more beams selected for multi-beam full-duplex communication for the second device, wherein the multi-beam full-duplex communication allows the second device to transmit uplink communication simultaneously on at least a first beam and receive downlink communication on at least a second beam in the same frequency band based on the DCI generated by the first device.

In some examples, transmitting the DCI may include transmitting a DCI transmission from a first device to the second device from a first component carrier to facilitate multi-beam full-duplex communication for the second device on a second component carrier.

[0102] Transmitting the DCI may further include activating at least one SPS configuration and at least one configured permission (CG) for the first UE via the DCI transmitted to the second device. In some aspects, the DCI further identifies that the second device is configured to use at least a first beam for uplink communication and at least a second beam for downlink communication for periodic communication using multi-beam full-duplex communication. The method may also include deactivating at least one SPS configuration and at least one CG for the first UE via the DCI transmitted to the second device. In some aspects, activating at least one SPS configuration and at least one CG may include transmitting a DCI transmission from the first device to the second device from a first component carrier to facilitate multi-beam full-duplex communication for the second device on a second component carrier.

[0103] In some aspects, the method may further include transmitting a wake-up signal (WUS) from the first device to the second device to wake the second device from a sleep mode, wherein the WUS includes the DCI. The DCI may be included within the WUS, which determines whether the operation during the subsequent discontinuous reception (DRX) activation period is for downlink communication, uplink communication, or full-duplex uplink and downlink simultaneous communication.

[0104] The method may further include transmitting a first-stage 1DCI from a first device to a second device via sidelink communication during a first time period, wherein the first-stage 1DCI includes preliminary scheduling information for scheduling full-duplex communication for uplink and downlink sidelink communication. The method may further include transmitting a second-stage 2DCI from the first device to the second device via sidelink communication during a second time period. Additionally, the method may include receiving a third-stage 2DCI from the second device via sidelink communication during the second time period, wherein the second-stage 2DCI and the third-stage 2DCI provide complete scheduling information for decoding data in the PSSCH.

[0105] Additionally or alternatively, the method may include transmitting a first-stage 1DCI from a first device to a second device via sidelink communication during a first time period. The method may also include receiving a second-stage 1DCI from the second device via sidelink communication during the first time period, wherein the first and second DCIs include preliminary scheduling information for scheduling full-duplex communication for uplink and downlink sidelink communication.

The method may further include receiving a fourth-stage 2DCI from the second device via sidelink communication during the second time period, wherein the third and fourth-stage 2DCIs provide complete scheduling information for decoding data in the PSSCH.

[0106] In some aspects, the method may include configuring two separate search spaces for each of the first UE and the second UE to transmit and receive data simultaneously on the PSSCH. Alternatively, the method may include configuring a single separate search space for each of the first UE and the second UE to transmit and receive data simultaneously on the PSSCH.

[0107] All aspects of frame 620 can be referenced. Figure 5 The transceiver 554 described herein performs this action. Thus, the transceiver 554, DCI generation component 550, modem 314, processor 312, and / or UE 104 or one of their sub-components may be defined as means for transmitting the DCI to a second device to configure it for multi-beam full-duplex communication.

[0108] Figure 7 This is a block diagram of a MIMO communication system 700 including base station 102 and UE 104. The MIMO communication system 700 can be explained by referring to... Figure 1 The wireless communication access network 100 is described in various aspects. Base station 102 may be a reference. Figure 1 Examples of various aspects of the described base station 102 are provided. Base station 102 may be equipped with antennas 734 and 735, while UE 104 may be equipped with antennas 752 and 753. In the MIMO communication system 700, base station 102 can transmit data simultaneously on multiple communication links. Each communication link may be referred to as a "layer," and the "rank" of the communication link indicates the number of layers used for communication. For example, in a 2x2 MIMO communication system where base station 102 transmits two "layers," the rank of the communication link between base station 102 and UE 104 is 2.

[0109] At base station 102, transmit (Tx) processor 720 can receive data from a data source. Transmit processor 720 can process this data. Transmit processor 720 can also generate control symbols or reference symbols. Transmit MIMO processor 730 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, or reference symbols where applicable, and can provide the output symbol stream to transmit modulators / demodulators 732 and 733. Each modulator / demodulator 732 to 733 can process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator / demodulator 732 to 733 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a DL signal. In one example, the DL signal from modulators / demodulators 732 and 733 can be transmitted via antennas 734 and 735, respectively.

[0110] UE 104 can be a reference Figure 1 Examples of various aspects of UE 104 described in -2. At UE 104, UE antennas 752 and 753 can receive DL signals from base station 102 and can provide the received signals to modulators / demodulators 754 and 755, respectively. Each modulator / demodulator 754 to 755 can condition (e.g., filter, amplify, down-convert, and digitize) its respective received signal to obtain an input sample. Each modulator / demodulator 754 to 755 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 756 can obtain the received symbols from modulators / demodulators 754 and 755, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receive (Rx) processor 758 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide the decoded data to UE 104 as a data output, and provide the decoded control information to processor 780 or memory 782.

[0111] In some cases, processor 780 may execute stored instructions to instantiate full-duplex communication management component 350 (e.g., see [link]). Figure 1 and 3 In some cases, processor 740 may execute stored instructions to instantiate DCI generation component 550 (e.g., see...). Figure 1 and 5 ).

[0112] On the uplink (UL), at UE 104, transmit processor 764 can receive and process data from a data source. Transmit processor 764 can also generate reference symbols for a reference signal. Symbols from transmit processor 764 can be pre-encoded by transmit MIMO processor 766 where applicable, further processed by modulators / demodulators 754 and 755 (e.g., for SC-FDMA, etc.), and transmitted to base station 102 according to communication parameters received from base station 102. At base station 102, UL signals from UE 104 can be received by antennas 734 and 735, processed by modulators / demodulators 732 and 733, detected by MIMO detector 736 where applicable, and further processed by receive processor 738. Receive processor 738 can provide decoded data to data output and processor 740 or memory 742.

[0113] The components of UE 104 may be implemented individually or collectively using one or more ASICs adapted to perform some or all of the applicable functions in hardware. Each of the mentioned modules may be a means for performing one or more functions related to the operation of the MIMO communication system 700. Similarly, the components of base station 102 may be implemented individually or collectively using one or more application-specific integrated circuits (ASICs) adapted to perform some or all of the applicable functions in hardware. Each of the mentioned components may be a means for performing one or more functions related to the operation of the MIMO communication system 700.
