Abstract: A method that determines a resource at a first user equipment (UE) for a sidelink communication from the second UE to a first UE is described. In an exemplary embodiment, the method receives a request from the second UE to send data to the first UE. In addition, the method determines a preconfigured resource selection window that is used by the second UE. Furthermore, the method determines a first sensing result at the first UE. The determined first sensing result includes information to be reported to the second UE for a resource selection. The determined first sensing results has a plurality of first sensing types. Further, the method transmits the first sensing result from the first UE to the second UE.

Abstract: Techniques for changing a Transmission Configuration Indication (TCI) state by a user equipment (UE) operating in a wireless communications system are provided. The UE receives a first message including a TCI state change command from a network and determines, based on the first message, whether a time offset/frequency offset (TO/FO) and a reception (Rx) beam for a new TCI state are known by the UE. Based on the determination, the UE calculates a time delay of the UE to be prepared to receive a reference signal with the new TCI state, generates a second message indicating the time delay of the UE for the new TCI state, and transmits the second message to the network.

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 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 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: Devices, systems, and methods for Random Access Channel (RACH) configuration in Layer 1 (L1)/Layer 2 (L2) mobility. A user equipment (UE) may obtain a downlink (DL) Transmission Configuration Indicator (TCI) list from a first Transmission and Reception Point (TRP). The DL TCI list may include DL beam information, RACH Occasion (RO) information, and initial Bandwidth Part (BWP) information associated with each DL TCI of a plurality of DL TCIs related to the first TRP and multiple TRPs adjacent to the first TRP. The UE may receive a handover command from the first TRP via Downlink Control Information (DCI) in Li or Media Access Control (MAC) Control Element (CE) in L2. The handover command indicates a handover from the first TRP to a second TRP of the multiple TRPs for the UE, and includes a specified DL TCI related to the second TRP. The UE may determine RACH information related to the second TRP, based at least partly on the specified DL TCI related to the second TRP included in the handover command and the DL TCI list. The UE may then perform random access to the second TRP based on the RACH information related to the second TRP. The RACH information may include uplink (UL) beam information, RO information and Bandwidth Part (BWP) information for the UE to perform random access to the second TRP.
