Embodiment Construction

[0024] The embodiment of the present invention relates to a method for indicating a modulation and coding scheme during multi-user joint mapping. In the method, the main user of the multi-user joint mapping is determined; when the main user is a remote user, the near-end user of the multi-user joint mapping is determined; then the modulation and coding schemes of the main user and the near-end user are indicated. Through this method, the use of multi-user joint mapping technology when indicating the modulation and coding scheme of the user can improve the utilization of the spectrum resources scheduled by the system to the remote user; at the same time, the method improves the downlink throughput of the entire system through the layered scheduling method rate.

[0025] The specific implementation of the present invention will be further described below in conjunction with the drawings and embodiments.

[0026] The embodiment of the present invention provides a multi-user joint map...

Abstract

The embodiment of the invention discloses a method and a base station for indicating a modulation encoding scheme during multi-user joint mapping. The method comprises the following steps: determininga master call user of the multi-user joint mapping; when the master call user is a remote user, determining a near-end user of the multi-user joint mapping; and indicating the modulation encoding scheme of the master call user and the near-end user. The embodiment of the method can improve the utilization ratio of system scheduling to a frequency spectrum resource of the remote user by adopting the multi-user joint mapping technology, and improve the downlink throughput of the whole system simultaneously by adopting a method for hierarchical scheduling.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and a base station for indicating a modulation and coding scheme during multi-user joint mapping. Background technique [0002] AMC (Adaptive Modulation and Coding, adaptive modulation and coding) technology is widely used in existing wireless communication systems, including GSM (Global System for Mobilecommunication, Global System for Mobile Communication), CDMA (Code Division Multiple Access, code division multiple access) Address) and LTE (Long Term Evolution, Long Term Evolution) and so on. In AMC technology, the receiving end estimates the channel and feeds back the estimation result to the sending end, and the sending end adjusts the modulation and coding method used by the sending end according to the characteristics of the channel. In the time-varying channel environment in wireless communication, AMC can enhance the reliability of transmission an...
