Methods, Devices And Medium For Communication

Abstract: Example embodiments of the present disclosure relate to a solution for random access (RA) procedure initiation. In this solution, a terminal device receives, from a first network device, a first physical downlink control channel (PDCCH) order to trigger a random access (RA) procedure for L1/L2 triggered mobility (LTM). The first PDCCH order indicates a first RA resource. The terminal device determines whether the first PDCCH order indicates a first cell of the first network device or a second cell of a second network device for handover. The terminal device is served in the first cell. If the first PDCCH order indicates the second cell, the terminal device initiates the RA procedure towards the second cell using a second RA resource, with the first RA resource in the first PDCCH order ignored. The second RA resource is configured by the second network device for the terminal device.
