  • Publication number: 20230042073
    Abstract: Aspects presented herein may enable FD devices to apply power backoff and/or power allocation prioritization rules that are specific to FD transmissions. In one aspect, a UE determines an FD specific power backoff associated with each of at least one transmission of a plurality of transmissions in a slot that is configured as an FD slot, each FD specific power backoff is based on whether a corresponding transmission would cause self-interference with a DL reception in the FD slot, and the plurality of transmissions are overlapping in time. The UE determines a transmission power for each of the at least one transmission in the FD slot based on the determined FD specific power backoff for each of the at least one transmission. The UE transmits one or more of the at least one transmission based on the determined transmission power for the corresponding transmission.

  • Patent number: 11569932
    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: 20230028810
    Abstract: Methods, systems, and devices for wireless communication at a first user equipment (UE) are described. A UE may receive a control signal indicating a set of durations. A duration of the set of durations may be scheduled for uplink resources and additional resources including downlink resources, flexible resources, or both. The UE may further receive an indication of a slot format configuration permitting sidelink communications on the uplink resources during the duration scheduled for the uplink resources and the additional resources. Upon identifying that sidelink communications are permitted, the UE may transmit a sidelink transmission using the uplink resources and during the duration.

  • Publication number: 20230018272
    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive control signaling indicating a first semi-static configuration for transmitting uplink signaling and a second semi-static configuration for receiving downlink signaling. In some cases, the UE may operate using half-duplex communications and may monitor for a transmission direction conflict between the first semi-static configuration and the second semi-static configuration during a transmission time interval. The UE may communicate, according to a priority rule, one of an uplink signal in accordance with the first semi-static configuration or a downlink signal in accordance with the second semi-static configuration during the transmission time interval based on the monitoring. Additionally, or alternatively, the UE may drop one of the uplink signal or downlink signal according to the priority rule.

  • Publication number: 20230015244
    Abstract: A wellbore assembly includes a cable and a wellbore tool. The wellbore tool is coupled to the downhole end of the cable. The wellbore tool includes a housing, one or more sensors, a packer, and a controller. The one or more sensors are coupled to the housing or to the cable or both. The sensors detect one or more parameters of the wellbore tool or the cable or both. The controller is coupled to the housing. The controller is electrically coupled to one or more sensors and is operationally coupled to the packer. The controller determines, with the wellbore tool parted from the cable and based on information received from the one or more sensors, an indication of the wellbore tool in free fall. The controller activates, based on the determination, the packer to expand the packer and set the wellbore tool on a wall of the wellbore.
