Abstract
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.

A method for establishing a wireless connection between a user equipment (UE) device and a base station in unlicensed radio frequency (RF) spectrum, comprising:
- receiving, at the UE device, a plurality of RF signals broadcasted by the base station;
- identifying a selected RF signal of the plurality of RF signals based on a maximum received signal level;
- detecting, in the selected RF signal, a plurality of slots including control information;
- incrementing a counter each time a slot including control information is detected in the selected RF signal;
- and
- in response to the counter exceeding a threshold value, identifying a first channel occupancy time (COT1) of the base station from control information transmitted over the selected RF signal.
A user equipment (UE) device, comprising:
- an antenna;
- a transceiver communicatively coupled to the antenna;
- a memory;
- and
- a processor communicatively coupled to the memory, wherein the processor is configured to execute instructions stored in the memory to:
- identify a selected radio frequency (RF) signal of a plurality of RF signals received via the antenna and the transceiver, the selected RF signal having a maximum received signal level,
- detect, in the selected RF signal, a plurality of slots including control information,
- increment a counter each time a slot including control information is detected in the selected RF signal, and
- in response to the counter exceeding a threshold value, identify a first channel occupancy time (COT1) of a base station separate from the UE device, from control information of the selected RF signal.
