DMRS INDICATION METHOD AND SYSTEM, BASE STATION AND USER EQUIPMENT

摘要

Disclosed is a demodulation reference signal (DMRS) indication method, comprising: a base station allocating designated DMRS ports, numbers of layers and orthogonal cover code (OCC) lengths to a user equipment (UE) according to a DMRS configuration parameter indication table, wherein a plurality of DMRS configuration parameter indication entries with a plurality of OCC length combinations of at least two OCC lengths are recorded in the DMRS configuration parameter indication table; according to DMRS configuration parameter information allocated to the UE, generating corresponding DMRS indication information, and sending the DMRS indication information to a corresponding UE. Also disclosed at the same time are a base station, a UE and a DMRS indication system.
