Radio resource management (RRM) signals for a RRM procedure may be adjusted for a user equipment (UE) or a cell operating in a low power mode, such as by relaxing, canceling, or prioritizing some RRM signals with respect to other signals based on power conditions at the UE or the cell.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may select a precoder from a codebook for precoding one or more signals for transmission to a receiver. The transmitter may select the precoder from the codebook based on antenna configurations at the transmitter and the receiver. The precoder may be constructed using one or more Slepian sequences. In some implementations, the Slepian sequences may be associated with a quantity of transmit antennas at the transmitter. For instance, a length of each Slepian sequence may correspond to (for example, be equal to) a quantity of transmit antennas at the transmitter. Further, the Slepian sequences may be associated with a bandwidth within which to concentrate the one or more signals. Once the transmitter selects the precoder, the transmitter may precode the one or more signals and transmit the precoded signals to the receiver.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for configuration of a CLI report that accurately characterizes the CLI experienced by the victim UE. A base station may transmit to the victim UE, a configuration for CLI reporting associated with one or more channel state information interference measurement (CSI-IM) resources. The victim UE may generate a CLI report based on the configuration for CLI reporting and the CSI-IM resources. The victim UE may transmit the CLI report to the base station. The base station may use the CLI report to mitigate the CLI, for example, by scheduling the aggressor UE and the victim UE to reduce CLI experienced by the victim UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify and schedule a set of bits in the physical uplink shared channel (PUSCH) for transmission of feedback for downlink transmissions occurring after transmission of the uplink grant scheduling the PUSCH. After receiving the uplink grant, a user equipment (UE) may receive control channel (PDCCH) transmissions that schedule downlink transmissions. The UE may monitor for and generate feedback for the downlink transmission. The UE may then utilize the bits indicated by the UL grant to transmit the feedback. In some examples, the UE may determine whether the indicated bits are adequate to transmit the feedback for the later downlink transmissions. When the UE determines that the extra bits are not adequate (e.g., there are not enough bits), then the UE may determine to transmit the feedback separate from the PUSCH resources scheduled by the uplink grant.

Abstract: Some techniques and apparatuses described herein provide reporting of multiple feedbacks for a same transport block (TB) or a same code block group (CBG) of a signal, such as a physical downlink shared channel. Thus, in case of a failure to decode a signal via a first set of antennas, a user equipment (UE) can perform a second decoding attempt via a second set of antennas (before or after transmitting first feedback). The UE may report a result of the first decoding attempt in a first feedback, and may report a result of the second decoding attempt in a second feedback. Some techniques and apparatuses described herein also provide soft feedback (e.g., information other than a binary acknowledgment (ACK) or negative ACK (NACK)) for a transmission, such as information indicating whether a second attempt to decode the transmission is likely to be successful.
