摘要:
Embodiments of the invention disclose an information notification and timing advance acquisition method, system and device, relate to the field of wireless communications and address the problem of how a UE acquires a Timing Advance (TA) for uplink transmission in a cell newly added in a set of cells configured for the UE. In the invention, a base station sends mapping relationships between cell and Timing Advance, TA, group to a UE, and the UE determines a TA group corresponding to a newly added cell configured for the UE by the base station according to the mapping relationships; determines whether there is a cell, having established uplink synchronization with the based station, in the TA group; and if so, then the UE regards a TA of the cell as a TA for uplink transmission in the newly added cell; otherwise, the UE acquires a TA for uplink transmission in the newly added cell by initiating a random access procedure. Apparently with the invention, the UE can acquire a TA for uplink transmission in the newly added cell.

A method for indicating and determining a carrier scheduling mode in a Long Term Evolution-Advanced (LTE-A) system is disclosed in the present invention. The method is that: a network device determines whether a component carrier adopts a cross-carrier scheduling mode to perform resource scheduling, and transmits first indication information that indicating whether the component carrier adopts the cross-carrier scheduling mode to perform the resource scheduling to a User Equipment (UE), so as to indicate the UE to determine whether adopting the cross-carrier scheduling mode to perform the resource scheduling on a component carrier supported by the UE itself according to the received first indication information. By adopting the present solution, the UE supporting multi-carriers in the LTE-A system is able to determine which mode one certain component carrier or several certain component carriers adopt to perform the resource scheduling, thereby performing data reception/transmission correctly.
