Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first configuration to receive a downlink communication in a set of symbols of a slot via a first duplex mode, wherein the slot is configured as a flexible or a full duplex slot. The UE may receive a second configuration to transmit an uplink communication in the set of symbols via a second, different duplex mode. At least one of the first duplex mode or the second duplex mode may be a half duplex mode. The UE may, based at least in part on a set of collision mitigation rules, receive the downlink communication in the set of symbols of the slot and/or may transmit the uplink communication in set of symbols of the slot. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a collection of reference signal transmissions. The UE may identify a resource overlap between the collection of reference signal transmissions and another resource that is unavailable for reference signal transmissions. The UE may identify one or more transmission properties for the collection of reference signal transmissions. The UE may determine, based at least in part on the one or more transmission properties and the resource overlap, whether to omit one or more of the reference signal transmissions of the collection of reference signal transmissions in the corresponding resource overlap or to delay transmission of the collection of reference signal transmissions. The UE may transmit at least a portion of the collection of reference signal transmissions based at least in part on the determining.

Abstract: Methods, systems, and devices for wireless communications are described. A method for wireless communication may include receiving a single frequency networked composite reference signal (SFNed RS) at a first port of a user equipment (UE) and receiving a reference signal (RS) at a second port of the UE that is different than the first port of the UE. The method may also include performing channel estimation for at least one of the first port or the second port based at least in part on receiving the SFNed RS and the RS. A method for wireless communication may include transmitting a first portion of an SFNed RS from a first port of a first transmit/reception point to a UE and transmitting a downlink control information message to the UE that indicates at least one transmission configuration indicator state identifier that identifies the SFNed RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) transmission that includes a guard band indication that indicates a guard band between an uplink frequency resource allocation and a downlink frequency resource allocation. The UE may communicate using the uplink frequency resource allocation and the downlink frequency resource allocation and based at least in part on the guard band. Numerous other aspects are described.

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.

Abstract: A clutter-induced interference at a base station is mitigated through a command from the base station to a user equipment that commands the user equipment to transmit using an increased transmit power. During acquisition, the command may comprise a SIB. During a connected mode of operation, the command may comprise a TPC message, assistance information, an RRC message, or a DCI message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may transmit configuration information indicating a first precoding matrix indicator (PMI) parameter and a second PMI parameter, wherein the first PMI parameter is associated with non-simultaneous activity of a distributed unit (DU) and a mobile termination (MT), and wherein the second PMI parameter is associated with simultaneous activity of the DU and the MT. The wireless node may perform a communication in accordance with a selected PMI parameter of the first PMI parameter and the second PMI parameter based at least in part on whether the DU and the MT are simultaneously active. Numerous other aspects are described.

The apparatus transmits or receives a channel having a highest priority between the channels that are scheduled to collide with each other. The channel comprises at least one of an UL transmission, a DL reception, an SL transmission, or an SL reception. The apparatus enables simultaneous reception or transmission of the channel using a FD operation based on at least one condition.

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.
