Document Type and Number:
WIPO Patent Application WO/2010/124597
Kind Code:
A1
Abstract:
A sounding reference signal (SRS) transmission method and apparatus in carrier aggregation scenario are provided in the invention, being applied to an advanced long-term evolution system. The transmission method comprises: a base station configures a group or a plurality of groups of SRS configuration parameters for an uplink component carrier required to be measured by a user equipment in carrier aggregation scenario, and transmits the parameters to the user equipment (801); according to the received SRS configuration parameters, the user equipment transmits the SRS to the base station (802). The invention can maintain the compatibility with the user equipment of the long-term evolution system and optimize the performance in transmitting the measurement signal when the user equipment of the advanced long-term evolution system adopts the carrier aggregation technology.
