Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of synchronization signal block (SSB) configurations for a corresponding set of frequency resource sets configured for communications in a shared frequency spectrum band. The UE may perform a listen-before-talk (LBT) procedure for each frequency resource set. If an LBT procedure is successful, the UE may select and communicate with a base station on the corresponding frequency resource sets. Accordingly, the UE may receive one or more SSBs from the base station on the selected frequency resource sets based on SSB configurations, which may indicate a floating or fixed configuration for SSBs. The UE may perform radio resource management (RRM) and radio link monitoring based on receiving the SSBs in one or more of the selected frequency resource sets according to the corresponding SSB configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, using one or more beams included in a first beam group associated with the UE, a channel occupancy ratio (CR) for the first beam group. The UE may perform an action if the CR for the first beam group does not satisfy a CR limit associated with the first beam group. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to determining channel state information (CSI) on a component carrier. In an example operation, a device determines a mapping between first time-frequency resources corresponding to a first component carrier (CC) and second time-frequency resources corresponding to a second CC using a prediction algorithm. The device receives, from a base station, a channel state information reference signal (CSI-RS) on the first time-frequency resources corresponding to the first CC and measures first CSI on the first time-frequency resources corresponding to the first CC based on the received CSI-RS. The device further predicts second CSI on the second time-frequency resources corresponding to the second CC based on the measured first CSI using the prediction algorithm. The device then generates a CSI report based on the predicted second CSI and sends the CSI report to the base station.

Abstract: A UE may determine that two or more resources on two or more beams from a base station have phase continuity. The UE may determine, based on the two or more resources on the two or more beams having the phase continuity, a joint channel information associated with the two or more beams using individual measurements respectively corresponding to the two or more beams. The UE may then transmit, to the base station, a group-based beam report including the joint channel information. The base station may provide the UE with an indication that the two or more resources on the two or more beams from the base station have phase continuity. The base station may receive the group-based beam report from the UE based on the indication, and the base station may configure communication with the UE on a joint channel based on the group-based beam report.

Abstract: Aspects are provided that allow a base station to provide a user equipment (UE) multiple timing opportunities to transmit an acknowledgment to a pre-grant (APG) after receiving a pre-grant for a downlink transmission. The base station transmits to the UE a pre-grant for a downlink transmission from the base station, the pre-grant triggering a plurality of timing opportunities for the UE to send an APG to the base station. The UE performs, after receiving the pre-grant, a clear channel assessment (CCA) during at least one timing opportunity of the plurality of timing opportunities. The UE transmits one or more APGs to the base station when the CCA is successful, and the UE receives the downlink transmission from the base station in response to the one or more APGs. The UE transmits the one or more APGs to the base station until the downlink transmission is received from the base station.

Abstract: Methods, systems, and devices for wireless communications are described in which a transmitting device using shared radio frequency spectrum may perform a listen before talk (LBT) procedure for at least a minimum dwell time and, upon successful completion of the LBT procedure, may occupy the spectrum for up to a duration of a channel occupancy time (COT). The transmitting device may discontinue transmitting during the COT for a gap period, and resume transmitting subsequent to the gap period without performing another LBT procedure. The minimum dwell time may be based on a periodicity of a channel reservation signal transmitted by one or more other devices using the shared radio frequency spectrum. In some cases, the transmitting device may schedule one or more receiving devices with resources for transmissions during the COT, and the receiving devices may perform a LBT that is non-adjacent with an associated transmission.
