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.

Abstract: Techniques described herein may include a special scheduling cell (sSCell) provided for dynamic spectrum sharing (DSS). The sSCell may schedule a primary cell of a master cell group (MCG) or a primary cell of a secondary cell group (SCG). The primary cell may be referred to as a special cell or SpCell. The sSCell may be activated and/or deactivated, enter in or exit from a state of dormancy, and radio link monitoring (RLM), beam failure recovery (BFR), and cell grouping parameters may be provided. Techniques described herein include configuring a UE-specific search space (USS) with non-fallback downlink control information (DCI), USS with fallback DCI, and overall search space for DSS enhancement.

Abstract: Provided is a method for a user equipment (UE). The UE obtains, from a network device, a first configuration information. The first configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS). The first resource set for the AP-SRS includes a first list of slot offsets. The UE decodes a second configuration information from the network device. The second configuration information indicates a reference slot and a first slot offset of the first list of slot offsets. The UE generates the AP-SRS for transmission to the network device based on the reference slot and the first slot offset.
