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.

Abstract: Some embodiments are disclosed for Uplink (UL) Transmission (Tx) switching in a wireless network. Some embodiments a base station (BS) can receive first UL Txs, transmit, a dynamic trigger signal for UL Tx switching, where a number of configured UL Tx switching bands, M, is greater than a maximum number of UL Tx chains, N, where M and N are integers. The BS can receive second UL Txs according to the dynamic trigger signal. In some examples, the first UL Txs and the second UL Txs correspond to a first pair of bands of the M configured UL Tx switching bands, or the first UL Txs correspond to a first pair of bands of the M configured UL Tx switching bands, and the second UL Txs correspond to one band of the first pair of bands and a different band of the M configured UL Tx switching bands.

Abstract: Some aspects relate to apparatuses and methods for implementing mechanisms for providing signaling and procedures to indicate a mode of communication of a wireless communication system. For example, a base station is configured to determine a mode of communication for a cell associated with the base station. The mode of communication can include one of a full-duplex mode or a half-duplex mode. The base station can further generate system information to enable initial access by a user equipment (UE) to the cell. A portion of the system information can indicate the mode of communication for the cell. The base station can also transmit the system information to the UE.
