A radio communications system, a base station device, and a wireless communication method

Title:

A radio communications system, a base station device, and a wireless communication method

Document Type and Number:

Japanese Patent JP6081074

Kind Code:

B2

Abstract:

A base station apparatus for a radio communication system that comprises the base station apparatus configured in compliance with an LTE-Advanced system standard and a user terminal configured to to perform radio communication with the base station apparatus. The base station apparatus comprises a generating section that generates uplink reference signal information related to an uplink DM-RS (Demodulation-Reference Signal) and a notifying section that notifies the user terminal of the uplink reference signal information using an RRC Connection Reconfiguration signal. The uplink reference signal information comprises information about an amount of offset from a physical uplink control channel sequence.
