Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a set of sensing resources to be used by a first user equipment (UE) for transmission of sensing signals. The base station may receive one or more uplink signals from a second UE, and determine interference at the second UE associated with the sensing signals transmitted by the first UE based at least in part on the set of sensing resources, the one or more uplink signals received from the second UE, or both. The base station may transmit, based at least in part on determination of the interference at the second UE, a configuration message to at least one of the first UE or the second UE. The configuration message may include an indication of a parameter adjustment pertaining to at least one of transmission of the sensing signals by the first UE or downlink reception by the second UE.

Abstract: Certain aspects of the present disclosure provide techniques for high speed beam management. A method that may be performed by a user equipment (UE) includes receiving beamformed signals from at least one base station (BS); determining that the UE is in a high mobility state and one or more parameters associated with the high mobility state, based on the received signals; transmitting at least one of the one or more parameters to the at least one BS; and communicating with the at least one BS based on the one or more parameters.

Abstract: Certain aspects of the present disclosure provide techniques that may for configuration of parameters for monitoring for a combination downlink control information (DCI) that schedules data and/or reference signal transmissions in multiple cells. An example method generally includes determining, a blind decode (BD) limit and a control channel element (CCE) limit based on a scaling factor less than one, determining physical downlink control channel (PDCCH) parameters based on the BD limit and the CCE limit for monitoring for a combination downlink control information (DCI) that schedules at least one of data or reference signal (RS) transmissions in multiple cells, and monitoring for the combination DCI based on the determined PDCCH parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a victim user equipment (UE) may measure a cross-link interference strength from an aggressor UE based at least in part on an uplink transmission from the aggressor UE colliding with a downlink transmission to the victim UE. The victim UE may transmit cross-link interference information to the aggressor UE on a sidelink channel. For example, the cross-link interference information transmitted to the aggressor UE may indicate at least the cross-link interference strength measured by the victim UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a measurement of a wireless signal from a first base station of a network, the measurement comprising one or more of: a Doppler shift of the wireless signal or an angular variation of the wireless signal; determine that a high speed train or tunneling (HSTT) event has occurred based at least in part on the measurement; provide, to the first base station, an indication that the HSTT event has occurred; and receive, from the first base station, configuration information to: configure the UE for a handover to a second base station of the network, configure the UE for beam switching, or cause the UE to change a connection state. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station operating in full-duplex mode may provide for reception of one or more higher priority transmissions using at least partially overlapping time-frequency resources as used for transmission of lower priority communications. In order to mitigate self-interference at the base station, a transmission power used for the overlapping time-frequency resources may be reduced. The base station may provide an indication of a subset of resources that have a reduced transmission power, an amount of the power reduction for the subset of resources, or both.

Abstract: Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.
