Methods and systems for establishing a connection between devices in unlicensed radio frequency spectrum

A method for establishing a wireless connection between a user equipment (UE) device and a base station in unlicensed radio frequency (RF) spectrum includes (a) receiving, at the UE device, a plurality of RF beams broadcasted by the base station, (b) identifying a selected RF beam of the plurality of RF beams having control information with a maximum received signal level, and (c) identifying a first channel occupancy time (COT1) of the base station from control information of the selected RF beam.

Feedback prioritization for wireless communications

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of channel state processes scheduled to be performed. The UE may receive a channel state feedback request corresponding to another set of channel state processes. The combination of the set of channel state processes and the other set of channel state processes may be greater than an amount that the UE may process at a given time. The UE may determine a priority for the channel state processes either on an individual or group basis. The UE may determine channel state process (es) to drop based on the determined priorities, and may perform the remaining channel state processes. The UE may generate and transmit a channel state feedback report message based on the performed channel state processes.
