The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a communication system is provided. The method includes transmitting, to a base station, capability information indicating a capability for state information (CSI) report with Doppler information, receiving, from the base station, configuration enabling a time correlated CSI report, obtaining the time correlated CSI report including precoding matrix indicator (PMI) indicating the Doppler information based on one or more CSI-reference signals (CSI-RS), and transmitting the time correlated CSI report to the base station.

A network device is provided that uses power measurements to measure a relative phase between a received signal from a reference antenna in a plurality of antennas and a received signal from each antenna in the plurality of antennas except the reference antenna. The network device may use a direct phase measurement to measure the phase of other received signals from additional antennas.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may precode a physical sidelink control channel (PSCCH) communication using a first delay-Doppler precoder. The UE may precode a physical sidelink shared channel (PSSCH) communication using one or more second delay-Doppler precoders. The UE may transmit the PSCCH communication and the PSSCH communication in a slot after precoding the PSCCH communication and the PSSCH communication. Numerous other aspects are described.

For improved messaging reliability in 5G and 6G, mobile users and their base stations can adjust their transmission power according to the current location of the mobile user. Each entity can maintain a map of known attenuation values, including “dead zones”, and can adjust their transmission power and/or reception gain to compensate. Instead of constantly exchanging location-update messages, the users can indicate their speed and direction, and the base station (or other users) can extrapolate the location versus time to determine a future location, and thereby determine the attenuation factor at the new position. In addition, the base station can use a map to follow the mobile user device's progress, and can thereby update the attenuation factor in real-time. If the mobile user makes a change, it can inform the base station at that time, or during initial access. Result: improved reliability, lower energy consumption, improved traffic safety.
