SIDELINK TRANSMISSIONS COHERENCY CONSIDERATIONS
A first UE may schedule a first sidelink transmission and a second sidelink transmission. A first DMRS associated with the first sidelink transmission and a second DMRS associated with the second sidelink transmission may be bundled for channel estimation associated with a second UE. The first UE may schedule a first uplink transmission. The first uplink transmission may be TDMed or FDMed with at least one of the first sidelink transmission or the second sidelink transmission. The first UE may transmit at least one of the first sidelink transmission, the second sidelink transmission, or the first uplink transmission. The bundling of the first DMRS and the second DMRS may be maintained or canceled.
TECHNIQUES FOR DOWNLINK AND UPLINK DATA DCI TRIGGERING FOR FULL DUPLEX UES IN A WIRELESS COMMUNICATION SYSTEM
In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for transmitting, by a UE to a network entity, a radio resource control (RRC) configuration message indicating a full-duplex capability of the UE; receiving, by the UE from the network entity, a downlink control information (DCI) message, wherein the DCI message enables concurrent transmission on an uplink channel and reception on a downlink channel by the UE; and communicating, between the UE and the network entity, based on the DCI message.
Techniques for bi-direction preemption indication transmissions
Aspects described herein relate to bi-direction preemption indication transmissions. In one example, a node such as an integrated access and backhaul (IAB) node may determine that a set of one or more resources are preempted for use for both an uplink transmission and a downlink transmission, and transmit, to a user equipment (UE), the bi-direction preemption indication indicating that the set of one or more resources are preempted for use for both of the uplink transmission and the downlink transmission. In another example, a UE may receive a bi-direction preemption indication indicating that a set of one or more resources are preempted for use for both an uplink transmission and a downlink transmission, and perform rate matching for both of the uplink transmission and downlink transmission based on the set of one or more resources indicated by the bi-direction preemption indication.
FULL DUPLEX TCI INDICATION UNDER UNIFIED TCI FRAMEWORK
A user equipment may be configured to implement full duplex transmission configuration indication (TCI) in a unified TCI framework. In some aspects, the user equipment may receive, from a base station, a plurality of TCI states, the plurality of TCI states including a full duplex TCI state corresponding to at least two channels for a first transmission link type and at least one channel for a second transmission link type. Further, the user equipment may apply the full duplex TCI state in accordance with a determined application time.
Hybrid in-band same frequency full-duplex and offset-frequency full-duplex wireless communication
Wireless communications systems and methods related to hybrid in-band same-frequency full-duplex (SFFD) and frequency-offset-frequency full-duplex (FD) wireless communication are provided. A user equipment (UE) transmits first data to a base station (BS) over a first frequency band while receiving second data from the BS the first frequency band responsive to a first pathloss between the UE and the BS satisfying a threshold for an SFFD operation. The UE transmits third data to the BS over a second frequency band while receiving fourth data from the BS over a third frequency band that is distinct from the second frequency band according to an offset-frequency FD operation responsive to a second pathloss between the UE and the BS failing to satisfying the threshold.
LENS COMMUNICATION WITH MULTIPLE ANTENNA ARRAYS
Methods, systems, and devices for wireless communications are described. A communications device may transmit a first signal. The first signal may be transmitted from a first antenna array of the communications device through a lens of the communications device in a direction. An energy of a portion of the first signal may be below a threshold based on a position of a second antenna array of the communications device. The portion of the first signal may correspond to a portion of a reflection of the first signal that overlaps with the position of the second antenna array. The communications device may concurrently receive, at the second antenna array, a second signal originating from another direction, where the second signal may be focused in the direction of the second antenna array based on the lens.
Apparatus and method for self-interference signal cancellation
The disclosure relates to a communication technique and a system for combining a 5G communication system with IoT technology to support a higher data rate after a 4G system. Based on 5G communication and IoT-related technologies, the disclosure may be applied to intelligent services such as smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail, and security and safety related services. The disclosure provides a method and apparatus that enable a communication device supporting full duplex to cancel the self-interference signal in the digital domain.
Base station, user equipment and wireless communication method
Provided are a base station, user equipment and wireless communication method related to RS collision cancellation in full duplex communication. A base station comprises: circuitry operative to perform at least one of a first processing and a second processing on downlink signals to be transmitted on a physical resource unit in a full duplex mode corresponding to one Transmission Time Interval (TTI); a transmitter operative to transmit the processed downlink signals on the physical resource unit to a first user NO equipment in a TTI; and a receiver operative to receive uplink signals on the physical resource unit from a second user equipment, wherein the first processing is use to be performed such that Code Division Multiplexing (CDM) is applied between the downlink signal and the uplink signal assigned on each of at least part of collided resource elements in the physical resource unit, each of the collided resource elements being assigned with both a downlink signal and an uplink signal at least one of which is a reference signal, and the second processing comprises suppressing at least part of the downlink signals assigned on the resource elements assigned with uplink reference signals thereon in the collided resource elements.
DYNAMICALLY STEERING DATA TRAFFIC SESSIONS BASED ON TRAFFIC TYPE
Dynamically steering data traffic sessions based on traffic type may include: determining that both frequency division duplex (FDD) and time division duplex (TDD) are available for an air interface between a user equipment (UE) and a base station (BS); determining a first traffic type expected over the air interface for a first data traffic session; based on at least the first traffic type, determining that FDD is a preferred duplex scheme for the first data traffic session; instructing the UE to use FDD over the air interface for the first data traffic session; determining a second traffic type expected over the air interface for a second data traffic session; based on at least the second traffic type, determining that TDD is a preferred duplex scheme for the second data traffic session; and instructing the UE to use TDD over the air interface for the second data traffic session.
SCALABLE SECURE SPEED NEGOTIATION FOR TIME-SENSITIVE NETWORKING DEVICES
A driver of an Ethernet controller may determine, based on an interrupt received from a PHY circuit coupled to the Ethernet controller, that a connection between the PHY circuit and a remote device was established using auto-negotiation over a physical communication medium. The driver may determine a speed of the connection. The driver may, based on a determination that the speed of the connection is not a first predetermined speed, enable auto-negotiation between the PHY circuit and the Ethernet controller to establish a link at a second speed that is different than the first predetermined speed.
