Title:

WIRELESS STATION, WIRELESS TERMINAL, AND TRANSMISSION TIMING CONTROL METHOD IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2013/018290

Kind Code:

A1

Abstract:

[Problem] To provide a wireless station, a wireless terminal, and a transmission timing control method in a wireless communication system, such that synchronization management of uplink signals of a plurality of cell groups is facilitated. [Solution] A wireless station (10) calculates transmission timing advances (TA1, TA2) for uplink signals, for each cell group (1, 2) comprising at least one cell having available uplink wireless resources, and notifies a wireless terminal (20) of the calculated transmission timing advances (TA1, TA2) for uplink signals, at once.
