Abstract: Apparatuses, systems and methods associated with asynchronous synchronization reference source selection and reselection for wireless communication devices are disclosed herein. In embodiments, one or more non-transitory, computer-readable media having instructions stored thereon, wherein the instructions, in response to execution by a user equipment (UE), cause the UE to establish a sidelink connection with a first synchronization reference (SyncRef) UE, and monitor for physical sidelink broadcast channel (PSBCH) synchronization signals from a second SyncRefUE, wherein the UE is to drop one or more subframes of data reception of the sidelink connection with the first SyncRef UE when the UE monitors for the PSBCH synchronization signals. Other embodiments may be described and/or claimed.

Abstract: Embodiments disclosed herein provide various aspects that would allow for Vehicle to Everything (V2X) or peer-to-peer (P2P) or sidelink (SL) communications. In an embodiment, a communication device may include: a memory for storing computer-readable instructions; and processing circuitry, configured to process the instructions stored in the memory to: obtain a first path loss between the communication device and a base station, wherein the communication device is coupled to the base station; calculate a second path loss based on one or more sidelink reference signal received power (S-RSRP) indicators received by the communication device, wherein the S-RSRP indicators are received from one or more communication devices within a communication range of the communication device; and determine a transmit (Tx) power of the communication device based on the first path loss and the second path loss.

Abstract: A communication device is provided that includes a receiver configured to receive a radio frequency signal. The communication device further includes a processor configured to determine a shift frequency based on a component radio frequency signal. The processor is configured to determine a second signal based on the radio frequency signal. The component radio frequency signal is based on the radio frequency signal and associated with a frequency related to the radio frequency signal represented in the frequency domain. The second signal is determined based on shifting frequencies related to the radio frequency signal represented in the frequency domain by the shift frequency.
