Description

Method for processing interference between terminal users under MU-MIMO scene and related equipment

Technical Field

The disclosure relates to the technical field of communication, and in particular relates to a method for processing interference between terminal users in a MU-MIMO scene and related equipment.

Background

The 5G NR base station generally adopts large-scale MIMO deployment in 3.5GHz and higher frequency bands, and MU-MIMO is a transmission mode widely adopted in 5G NR because of the advantages of improving the overall throughput of a network, supporting multi-user transmission in the same frequency at the same time and the like. However, in MU-MIMO scenario, there is interference between end users, and before Rel-16, the network side device (e.g. base station) mainly schedules channel information of each user to avoid such interference, but because the network side device needs to consider factors such as fairness, traffic demand and actual user position in scheduling, the influence of such interference on downlink receiving reliability in actual transmission is still larger. The 5G NR Rel-17 introduces an MMSE-IRC receiver for suppressing the interference of the multiplexing user terminal. Simulation results show that when the network side equipment adopts orthogonal precoding and random precoding, compared with the traditional MMSE (minimum mean square error) reception, the E-MMSE-IRC/R-ML receiver can obtain higher reliability of a receiving end by using higher network side information and higher complexity, and is incorporated into research content of 3GPP Rel-18 demodulation performance enhancement.

Therefore, how to provide a method for assisting a terminal to perform inter-terminal user interference processing in a MU-MIMO scenario according to the supporting capability information of the terminal is a technical problem to be solved.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

the interference processing capability information reporting module is used for reporting the supporting capability information for suppressing the interference between MU-MIMO users to the network side equipment;

and the auxiliary demodulation information receiving module is used for receiving auxiliary demodulation information sent by the network side equipment, wherein the auxiliary demodulation information is used for carrying out interference processing among MU-MIMO users when the auxiliary terminal receives downlink data.

27. An electronic device, comprising:

A processor; and

A memory for storing executable instructions of the processor;

Wherein the processor is configured to perform the method of inter-end user interference handling in a MU-MIMO scenario of any one of claims 1-24 via execution of the executable instructions.

28. A computer readable storage medium having stored thereon a computer program, which when executed by a processor implements the method for processing inter-end user interference in a MU-MIMO scenario according to any one of claims 1 to 24.
