Abstract

The invention provides a shared frequency band downlink multi-subband resource allocation method and a base station. The method comprises: the base station transmits downlink resources to user equipment (UE) through the same subframe of a radio frame, the downlink resources including control information carried by a PDCCH and data information carried by a PDSCH, so that the UE acquires the data information based on the control information of the downlink resources; wherein the downlink resources in the subframe of the radio frame are distributed according to a preset resource allocation strategy. In this method, the PDCCH and the PDSCH can be transmitted simultaneously by way of frequency division and time division in the same radio frame, and the dynamic resource allocation of the system can be realized, and the PDSCH service transmission efficiency can be effectively improved through reasonable allocation of resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a shared frequency band downlink multi-subband resource allocation method and a base station. Background technique [0002] With the continuous development of new wireless communication technologies, as well as the vigorous development of the mobile Internet and the Internet of Things industry, the demand for radio spectrum by various radio services has expanded rapidly, and spectrum resources have become increasingly scarce. The traditional management method of fixed allocation of private network frequencies is exclusive. Due to the business characteristics of industry users, this method is likely to cause relatively low utilization of wireless spectrum in the industry private network, spectrum resources are not fully utilized, and there is a certain degree of waste. Spectrum sharing can break the exclusive occupation of spectrum, open up more available sp...
