摘要

Coordinated multi-point (CoMP) transmissions in a cellular network is performed using multi-broadcast single frequency network (MBSFN) subframes. During CoMP transmission, demodulation reference signals (DRS) are placed in the one portion the MDSFN subframe, while cell-specific reference signals (CRS) are placed in a separate portion of the MDSFN subframe. Therefore, no CRS-DRS collision will occur during CoMP transmission.

主权项

1. A method for receiving coordinated multi-point transmissions in a cellular network, the method comprising:
receiving at a user equipment (UE) a coordinated multi-point transmission transmitted simultaneously from transmission points associated with plurality of base stations (NB), wherein demodulation reference signals (DMRS) associated with the transmission are configured in the same set of frequency resources, and the position of the DMRS do not overlap/collide with CRS (cell specific reference symbol) physical signals; and decoding at the UE the coordinated multi-point transmission from a stream of multi-broadcast single frequency network (MBSFN) subframes.
