Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a network entity may adjust a backoff power level for communications by the network entity in a first cell supported by the network entity. The network entity may transmit signaling that indicates an estimated level of interference in a second cell supported by a neighboring network entity based on the adjusted backoff power level. The network entity may receive a feedback message from the neighboring network entity that indicates downlink interference measurements by one or more UEs operating within the second cell. In some examples, the feedback message may indicate a difference in interference measurements obtained by the UEs before and after the backoff power level is adjusted by the network entity. The network entity may further adjust or maintain the backoff power level based on the feedback received from the neighboring network entity.

Abstract: Methods, systems, and devices for wireless communications are described. For example, described techniques provide for performing multipath fading equalization at a reconfigurable intelligent surface (RIS), allowing a receiving device to omit an equalization procedure or to perform a simpler equalization. A transmitting device, such as a network entity, may select a RIS that is within a sufficient proximity to a receiving device, such as a user equipment (UE), that multipath fading of the RIS to receiver wireless link is likely to be below a threshold. The network entity may configure the selected RIS with a phase matrix to perform over-the-air equalization to compensate for multipath fading over the network entity to RIS wireless link. The UE may omit an equalization procedure or may perform a simpler equalization procedure as compared to a scenario where the RIS does not compensate for multipath fading.

Abstract: Certain aspects of the present disclosure provide techniques for facilitating the use of random access channel occasions for full-duplex communication. An example method performed by a user equipment (UE) in a first group of UEs may include receiving, from a base station (BS) of a wireless network, a first indication indicating, from a first plurality of random access channel occasions (ROs) not available for use by a second group of UEs within the wireless network, a set of ROs that are available for use by the first group of UEs within the wireless network, receiving a first signal of a plurality of signals transmitted by the BS, and transmitting, in response to receiving the first signal, a random access preamble in a first RO of the set of ROs based on a mapping between the first signal and the first RO.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for signaling whether to generate cross-link interference (CLI) measurement reports based on a single CLI measurement occasion or based on multiple CLI measurement occasions. A network entity may indicate whether to generate a CLI measurement report based on a single most recent CLI measurement occasion or based on CLI measured over a number of CLI measurement occasions. The measuring user equipment (UE) may generate a CLI report based on a single most recent CLI measurement occasion or based on a statistical CLI measurement based on respective CLI measurements for each respective CLI measurement occasion of the number of CLI measurement occasions depending on the indication. The network entity may also indicate to the aggressor UE to repeat transmission of sounding reference signals using the same transmit beam during the CLI measurement occasions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a candidate pattern from a set of patterns for reference signals used to track phase error. The UE may transmit an indication of the selected pattern to a base station and receive, from the base station at least in part in response to the transmitted indication of the selected pattern, an indication of a configuration for the reference signals used to track phase error, the configuration indicating a pattern of the set of patterns, a number of reference signal groups, and a number of samples per reference signal group. The UE may receive the reference signals used to track phase error according to the indicated configuration.
