摘要： A user equipment (UE) is configured to perform a method for determining a timing reference for a secondary cell (SCell) in a secondary timing advance group (sTAG). The method includes selecting a SCell among a plurality of SCells within a sTAG as an uplink timing reference cell based on a predefined rule that is known at the UE and an eNB in communication with the UE. The method also includes receiving a downlink carrier from the selected SCell and determining, from the downlink carrier, a downlink timing used as a reference for an uplink transmission timing.

摘要： The present invention relates to an apparatus and method for performing uplink synchronization in a multi-component carrier system. A method for performing uplink synchronization according to the present invention comprises the steps of: receiving, from a base station, a message that indicates a time alignment value for adjusting an uplink time of a sub-serving cell; adjusting the uplink time on the basis of the time alignment value; and driving a validity timer, which indicates the period of validity of the time alignment value when the sub-serving cell is deactivated. According to the present invention, with respect to a sub-serving cell, which performs a random access procedure to ensure and maintain a time alignment value, the validity of the time alignment value and whether or not uplink synchronization in the sub-serving cell is made can be quickly ascertained, and efficiency of uplink data transmission can increase.

摘要： In a wireless network supporting aggregation of uplink component carriers, sounding reference signals, SRS, are transmitted (62) on an uplink, UL, primary component carrier. An activation command corresponding to an UL secondary component carrier, SCC, is received (64), in response to which the receiving transceiver determines (65) whether it has valid timing information for the UL SCC, wherein valid timing information for the UL SCC indicates that the UL SCC is UL synchronized. In response to this determination, transmission of SRS on the UL SCC is enabled (66) if the UL SCC is synchronized, when SRS is configured for the UL SCC. Otherwise, transmission of SRS on the UL SCC is prohibited (68) until the UL SCC is UL synchronized.
