Resource allocation method, system and related device

Abstract

The invention discloses a resource configuration method and system and a relevant device. A base station sends virtual bandwidth configuration information to a terminal through high-level configuration signalling, the virtual bandwidth configuration information indicates X virtual bandwidths corresponding to the terminal or indicates whether the virtual bandwidths are adopted or not, the system bandwidth of the terminal is divided into N sub-bandwidths, one virtual bandwidth corresponding to the terminal is composed of K sub-bandwidths, K, N and X are all positive integers larger than or equal to one, and K<N. The virtual bandwidths are configured, signalling cost in small cells can be lowered, interference cooperation between the small cells is supported, data transmission of the small cells is supported well under the condition of being compatible with an existing system and guaranteeing consistency of transmission and feedback, and frequency efficiency of the system is improved.

Description

technical field [0001] The present invention relates to the field of mobile wireless communication, in particular to a resource allocation method, system and related devices. Background technique [0002] In the mobile communication system, due to the time-varying characteristics of the wireless fading channel, there are a lot of uncertainties in the communication process. In this way, when the signal-to-noise ratio of the wireless fading channel is relatively ideal, the system throughput has indeed been greatly improved, but when the channel is in deep fading, it cannot guarantee reliable and stable communication. On the other hand, in order to ensure the reliability of communication , using low-order modulation with a low transmission rate and large redundant error-correcting codes for communication, that is, to ensure reliable and stable communication when the wireless channel is in deep fading. However, when the channel signal-to-noise ratio is high, due to the low trans...

Problems solved by technology

In the new evolved system of LTE-A, the number of small cells will increase significantly, so that the new evolved system can support more hotspots and have better edge coverage, and more small cells lead to a decrease in the signaling overhead of the system Significantly increased, more small cells also lead to a significant increase in inter-cell interference, resulting in a significant decrease in the efficiency of the entire system

[0038] At present, the number of small cell terminals is small, such as 1 or 2, and only 1 terminal may be scheduled in a subframe. In order to reduce signaling overhead and improve spectrum efficiency, it is necessary to optimize scheduling and feedback, and be compatible with existing systems as much as possible. Reduce the overhead of downlink control signaling and uplink feedback signaling and improve the spectral efficiency of the entire system under the condition of signaling design, but the existing standards cannot meet this demand
