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 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.

Abstract: A base station can include a transceiver and a processor communicatively coupled to the transceiver. The transceiver can enable wireless communication with a user equipment (UE) by a first component carrier (CC) in a first cell managed by the base station in a carrier aggregation (CA) wireless communication system. The processor can generate a system scheduling message to be transmitted on the first CC to the UE in the first cell, where the system scheduling message comprises a schedule of monitoring occasions for system information of a second CC by the UE in a second cell. Afterwards, the processor can transmit the system scheduling message on the first CC to the UE.

Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP). Other approaches include setting the fixed frame period length to different sizes for each UE, using a random number of skipped fixed frame periods, and the gNB configuring UEs with multiple semi-static channel access mode parameters.
