RESOURCE CONFIGURATION METHODS FOR DEDICATED DEMODULATION REFERENCE SIGNAL AND RELEVANT APPARATUSES

摘要

The embodiments of the present invention disclose resource configuration methods and relevant devices of a demodulation reference signal, wherein a resource configuration method of a demodulation reference signal may comprise: determining the number of transmission layers of the UE for transmitting uplink data; selecting combinational configurations of CS and OCC sequence necessary for generating DMRS sequences of respective transmission layers of the UE for transmitting uplink data, from one combinational configuration item of multiple combinational configuration items of CS and OCC sequence that are preset, directed to the maximum number of transmission layers supportable by the system, and usable for generating demodulation reference signal DMRS sequences of respective transmission layers, based on the determined number of transmission layers; generating and delivering to the UE a control signaling containing configuration indication information. The solutions of the embodiments of the present invention can simplify the complexity of a protocol describing the DMRS resource configurations, and is helpful for reducing inter-codeword DMRS interferences.
