Abstract

The embodiment of the invention discloses an orthogonal cover code (OCC) indication method, a demodulation reference signal (DMRS) processing method, a system and equipment, which relate to the field of wireless communication and are used for solving the technical problem that user equipment in the prior art cannot determine whether to use an OCC sequence or not and determine which OCC sequence to perform weighting processing on a DMRS. The OCC indication method comprises the following steps of: determining whether the user equipment (UE) is required to use the OCC sequence for performing the weighting processing on the DMRS to be transmitted or not by using a network side, determining the OCC sequence used for performing the weighting processing on the DMRS by the UE and transmitting the information of the OCC sequence to the UE if the UE is required to use the OCC sequence for performing the weighting processing on the DMRS to be transmitted, otherwise, transmitting the information indicating that the UE is not required to use the OCC sequence for performing the weighting processing on the DMRS to the UE. By the methods, the user equipment can determine whether to use the OCC sequence or not and determine which OCC sequence to perform the weighting processing on the DMRS according to the indication of the network side.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and equipment for orthogonal cover code indication and demodulation reference signal processing. Background technique [0002] The multiple-input multiple-output (MIMO) technology uses multiple antennas at both the transmitting end and the receiving end to transmit and receive data, so as to greatly improve the transmission performance and capacity of the system. [0003] In uplink transmission, MIMO transmission can be implemented through two methods: Single User Multiple Input Multiple Output (SU-MIMO) and Multi User Multiple Input Multiple Output (MU-MIMO). SU-MIMO uses spatial multiplexing technology to send multiple data streams of a user on the same time-frequency resource; while MU-MIMO uses the orthogonality between users to send data streams of multiple users on the same time-frequency resource. data. Without increasing the bandwidth, MIMO...
