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: A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.

Abstract: A user equipment is configured to receive a reference signal when secondary cell (SCell is to be activated. The UE receives a secondary cell (SCell) activation indication for activating an SCell, receives a reference signal (RS) triggering indication for triggering an RS prior to an expected SCell activation period, performs measurements on the triggered RS and activates the SCell based on the RS measurements.

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.
