Abstract: Methods, systems, and devices for wireless communication are described. Aspects of the disclosure describe narrow beam-based channel access that enables a device to communicate in a shared radio frequency spectrum band without performing channel access procedures. Specifically, aspects of the disclosure describe techniques for defining one or more directional beams as a narrow beam, where the relative narrowness of the beam may be determined in the context of interference (e.g., as opposed to being defined from a geometric perspective). For example, a particular beam may be determined to be a narrow beam, and therefore associated with communications in shared radio frequency spectrum bands without channel access procedures, based on one or more metrics and a number of spatial streams associated with the beam. A device may use such narrow beams for communications without channel access procedures in shared radio frequency spectrum bands.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: Aspects relate to beam management reports that enable selection of best antenna panel and beam combinations for uplink transmissions from a user equipment (UE) when one or more antenna panels of the UE are subject to a maximum permissible exposure (MPE) limit. The UE receives a reference signal at a plurality of antenna panels, wherein the reference signal is received in different beams on each of the plurality of antenna panels. The UE determines N beams providing highest measured strengths of the reference signal on at least one of the plurality of antenna panels, wherein the MPE limit is to be applied to the at least one of the plurality of antenna panels for uplink transmissions. The UE transmits a beam management report including reduced highest measured strengths of the reference signal in the N beams to account for the MPE limit.
