Abstract: A communication device includes one or more processors, configured to receive data representing each of at least a first waveform and a second waveform from a common control channel and data representing a third waveform from a data channel associated with the control channel; determine from the received data, channel state information for each of the first waveform and the second waveform; determine a Doppler shift between the channel state information for the first waveform and the channel state information for the second waveform; compare the determined Doppler shift to a predetermined Doppler shift threshold; and if the determined Doppler shift is less than the predetermined Doppler shift threshold, adjust the third received waveform by the determined Doppler shift and decode the adjusted third received waveform.

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.
