Abstract: Apparatuses, systems, and methods for selecting channel access mechanisms in wireless communications, and particularly in 3GPP NR-U. For example, an appropriate listen-before talk (LBT) channel access category (Cat) may be defined for certain messages, such as certain DL and/or UL control messages and certain RACH messages. For other messages, an appropriate Cat may be signaled by the base station, e.g., in a DCI message or SIB. Mechanisms are provided for the base station to signal to the UE certain channel access profile parameters, such as an appropriate LBT Cat, CAPC, and/or CP extension. Mechanisms are also provided for adjustment of contention window duration.

Abstract: Systems and methods provide multiple cell activation. A user equipment (UE) receives, from a wireless network, a command to activate multiple cells simultaneously. In response, the UE initiates cell activation procedures for the multiple cells. The cell activation procedures include waiting for an active transmission configuration indicator (TCI) indication. The UE monitors for the active TCI indication on any of the multiple cells. In response to receiving the active TCI indication on a first cell of the multiple cells, the UE determines one or more second cells of the multiple cells that share a same spatial relationship with the first cell according to one or more predetermined rule, and autonomously continues the cell activation procedures for the first cell and the one or more second cells.

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.
