  • Publication number: 20220386367
    Abstract: Methods, systems, and devices for wireless communications are described. A full-duplex device may perform a channel access procedure using multiple threshold values to determine whether self-interference at the full-duplex device is affecting the channel access procedure. For example, if a first amount of energy detected during a first sensing operation of the channel access procedure is determined to be between a first threshold value and a second threshold value, the full-duplex device may perform a self-interference measurement on the shared channel and may transmit on the shared channel if the self-interference measurement exceeds a self-interference threshold value. Additionally or alternatively, if the self-interference measurement does not exceed the self-interference threshold value, the full-duplex device may refrain from transmitting on the shared channel.

  • Publication number: 20220376818
    Abstract: In a wireless network, a user equipment (UE) may skip an uplink transmission associated with a dynamic uplink grant. In such cases, when the UE skips an uplink transmission that would have been concurrent with a downlink transmission, the UE may perform one or more mode-dependent control operations. For example, because the uplink transmission would result in a full-duplex operation if the UE were to perform the uplink transmission, the UE may reset a timer associated with switching from a full-duplex mode to a half-duplex mode and/or perform one or more mode-dependent control operations in the full-duplex mode. Alternatively, because the UE refrains from performing the uplink transmission that would have resulted in a full-duplex operation, the UE may maintain the timer associated with switching from the full-duplex mode to the half-duplex mode and/or perform the one or more mode-dependent control operations in the half-duplex mode.

  • Publication number: 20220377689
    Abstract: A user equipment (UE), such as a full-duplex UE, may receive a downlink transmission from a first transmit-receive point (TRP) in a full-duplex multi-TRP configuration. The UE may perform an uplink transmission to a second TRP in the full-duplex multi-TRP configuration based at least in part on a timing advance adjustment associated with the uplink transmission. The UE may apply the timing advance adjustment based at least in part on an indication received from a base station. The indication may be to set a timing advance offset to a value that satisfies a threshold value based at least in part on the downlink transmission and the uplink transmission being associated with two different TRPs. The downlink transmission and the uplink transmission may not be separated by a guard symbol when the downlink transmission and the uplink transmission are associated with the two different TRPs, which may improve a resource utilization.

  • Publication number: 20220346024
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) supporting full duplex communications may determine that a set of downlink messages to be transmitted from a base station to the UE overlaps in time with a set of uplink messages to be transmitted from the UE. Accordingly, the UE may determine a downlink transmission power adjustment value for the set of downlink messages. In some examples, the base station may indicate the downlink transmission power adjustment value to the UE via radio resource control (RRC) signaling, a downlink control information (DCI) message, or both. The UE may transmit the set of uplink messages while simultaneously receiving the set of downlink messages with a transmission power that corresponds to the downlink transmission power adjustment value. Adjusting the transmission power for the set of downlink messages may reduce self-interference at the UE, the base station, or both.
