Abstract: Techniques for changing a Transmission Configuration Indication (TCI) state by a user equipment (UE) operating in a wireless communications system are provided. The UE receives a first message including a TCI state change command from a network and determines, based on the first message, whether a time offset/frequency offset (TO/FO) and a reception (Rx) beam for a new TCI state are known by the UE. Based on the determination, the UE calculates a time delay of the UE to be prepared to receive a reference signal with the new TCI state, generates a second message indicating the time delay of the UE for the new TCI state, and transmits the second message to the network.

Abstract: A communication system provides reliable wideband communications with reduced power consumption in a user equipment (UE) receiver. A UE may include receiver circuitry to receive a radio frequency (RF) signal from a wireless network and output an analog baseband signal. The RF signal includes M copies of a duplicated signal in a frequency domain. The analog baseband signal includes the M copies of the duplicated signal uniformly offset from one another in the frequency domain by a bandwidth F and including a gap between adjacent copies. The UE further includes an anti-aliasing analog filter an analog to digital converter (ADC). The ADC samples an output of the anti-aliasing analog filter at a sampling frequency selected to obtain a digital baseband signal comprising a combined digital copy of the M copies of the duplicated signal folded over each other.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for channel occupancy rate determination of a channel between a user equipment (UE) and a base station in an unlicensed spectrum. A UE can perform measurements based on a measurement configuration from the base station, and further determine a channel occupancy rate of the channel based on the performed measurements. The measurement configuration indicates to the UE to perform an omni measurement or a directional measurement by using an antenna element of the UE. The UE can further transmit a report to the base station to indicate the channel occupancy rate.
