Document Type and Number:
WIPO Patent Application WO/2024/074002
Kind Code:
A1
Abstract:
Embodiments of the present application are related to a method and apparatus of supporting timing advance (TA) acquisition. An exemplary method includes: receiving, from a serving cell on an active bandwidth part (BWP), a physical downlink control channel (PDCCH) order triggering a physical random access channel (PRACH) transmission associated with a candidate cell of a set of candidate cells, wherein, the set of candidate cells is configured by higher layer, and a center frequency of synchronization signal (SS) /physical broadcast channel (PBCH) block (SSB) from the candidate cell is different from a center frequency of SSB from the serving cell; and transmitting, to the candidate cell, the PRACH transmission, wherein a time between a last symbol of the PDCCH order and a first symbol of the PRACH transmission is equal to or greater than a threshold timing gap, wherein the threshold timing gap is based on a radio frequency (RF) switching time.
