Enhanced pathloss reference signal measurement

Abstract

Embodiments of the present disclosure relate to enhanced pathloss reference signal (PL-RS) measurement. In an aspect, a terminal device receives, from a network device via a first cell, an activation command for activating at least one second cell. The terminal device receives, from the network device via the at least one second cell, at least one synchronized signal block (SSB) associated with the activation of the at least one second cell. The terminal device performs time and frequency synchronization based on the at least one SSB, and determines a first PL-RS based on the at least one SSB during the time and frequency synchronization .By implementing the embodiments of the present disclosure, the first PL-RS could be determined in parallel with / during the process of time and frequency synchronization and the terminal device is able to perform the PL-RS measurement before receiving the TCI activation command, thereby reducingSCell activation delay.
