Method and apparatus to improve aperiodic SRS (sounding reference symbol) in a wireless communication system

摘要

A method and apparatus are disclosed for aperiodic SRS improvement. In one embodiment, the method comprises configuring a UE (User Equipment) with aperiodic SRS. The method also comprises transmitting a PUSCH (Physical Uplink Shared Channel) on a last SC-FDMA (Single Carrier-Frequency Division Multiple Access) symbol in a UE-specific aperiodic SRS subframe if a Msg3 in the subframe is transmitted on the PUSCH. Furthermore, the method comprises not transmitting a PUSCH on a last SC-FDMA symbol in a UE-specific aperiodic SRS subframe if a Msg3 in the subframe is not transmitted on the PUSCH.

1. A method to implement SRS (Sounding Reference Symbol), comprising:
configuring a UE (User Equipment) with aperiodic SRS; and transmitting a PUSCH (Physical Uplink Shared Channel) on a last SC-FDMA (Single Carrier-Frequency Division Multiple Access) symbol in a UE-specific aperiodic SRS subframe if a Msg3 in the subframe is transmitted on the PUSCH, wherein the PUSCH does not overlap with a maximum SRS bandwidth.
