Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] The embodiment of the present invention discloses a method and related equipment for demodulation reference signal enhancement of DMRS. In the case that the bandwidth occupied by users in the MU-MIMO scene is not completely the same, the number of users who send DMRS at the same time can be increased, so that the system can be improved. spectrum resource utilization. Each will be described in detail below.

[0033] see figure 1 , figure 1 It is a schemati...

Abstract

Embodiments of the invention disclose a method for enhancing a demodulation reference signal and related equipment. The method comprises the following steps: a base station can send DMRS configuration information to M UE, DMRSs reported by the M UE according to DMRSs are received, and channel estimation is performed respectively aiming at the DMRSs reported by the various UE, wherein the M UE comprises the N first target UE performing uplink data transmission in an MU-MIMO mode, and at least two first target UE having partially overlapped occupied bandwidths exist in the N first target UE. The base station can receive a plurality of MU-MIMO users having the partially overlapped occupied bandwidths, DMRSs are reported at the same time, and then the channel estimation is performed according to the DMRSs, so the number of users simultaneously sending the DMRSs can be increased, and the frequency spectrum resource utilization rate of a system can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for enhancing a demodulation reference signal and related equipment. Background technique [0002] With the popularization and application of smart terminals and the continuous growth of mobile services, the demand for wireless transmission rate is increasing exponentially. High-speed, high-quality communication technology will become the research goal of the next generation communication system. The multi-antenna technology represented by Multiple-Input Multiple-Output (MIMO) is one of the best solutions to achieve the above-mentioned goals. However, the number of antennas and the transmission mode stipulated in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) agreement do not support multiple users to perform spatial multiplexing, thus greatly limiting the spectrum resource utilization of the system. In order to utilize spectrum...
