MIMO PHICH METHOD FOR ALLOCATING PHICH AND GENERATING REFERENCE SIGNAL IN SYSTEM USING SINGLE-USER MIMO BASED ON MULTIPLE CODEWORDS WHEN TRANSMITTING UPLINK

摘要

The present invention relates to a method for generating an uplink reference signal in a system supporting a plurality of uplink access transmission mode rolls. The method includes transmitting, by the base station, reference signal configuration information for a configuration of a reference signal to be transmitted in an uplink generated for each of the plurality of uplink access transmission modes to a user configured to operate in an uplink access transmission mode corresponding to the information, Transmitting an uplink grant on a physical downlink control channel (PDCCH) to a device; And receiving from the user equipment a subframe including a reference signal generated based on the reference signal configuration information, wherein the reference signal configuration information includes a cyclic shift value of the sequence of the reference signal.
