An uplink resource allocation method in smart grid

Abstract

The invention discloses an uplink resource allocation method in a smart power grid. The method comprises the following steps: writing a target data volume of to-be-transmitted buffer data into a BSR reported to an eNB by a DA; the eNB inquires a corresponding target quantized value of the target data volume in the data quantized mother table; the eNB inquires a target index value corresponding toa target data volume in a pre-defined data quantization sub-table corresponding to the target quantization value, and each quantization value in the data quantization mother table is correspondingly provided with a data quantization sub-table; the eNB distributes uplink resources for the DA according to the target index value, and configures and authorizes the distributed uplink resources in a physical downlink control channel (PDCCH); and the DA monitors the PDCCH to obtain the configuration and authorization, and uploads the to-be-transmitted buffer data in the authorized uplink resource according to the configuration. According to the invention, the uplink resource distribution efficiency can be improved, the resource waste rate is reduced, and no extra signaling overhead is introduced.

Description

Technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an uplink resource allocation method in a smart grid. Background technique [0002] The emergence of smart grids is based on the development of high-speed communication networks. It can apply modern technologies, such as communications, information, computers, and control, to meet the power needs of users and optimize resource allocation to ensure the safety, reliability and economy of power supply. The 3GPP Long Term Evolution (LTE) is considered a promising solution for the smart grid because of its low latency and large bandwidth. However, LTE was not originally used for smart grid applications, and data generated by smart grids has specific requirements different from traditional data or voice communications. [0003] LTE uplink resource scheduling is performed by the eNB (radio base station). The eNB scheduler needs to obtain information about the RB (Radio...
