Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig configuring a port selection codebook comprising a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based on the CSI-ReportConfig, the determines, for the port selection matrix W1, up to L CSI reference signal (CSI-RS) ports out of P CSI-RS ports configured for measuring and reporting CSI. For the frequency basis selection matrix Wf, the UE determines up to Mv frequency basis out of N frequency basis. For the combinational coefficient matrix W2, the UE determines up to L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the combinational coefficient matrix W2, and the frequency basis selection matrix Wf to the base station.

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.

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.
