Problems solved by technology

However, the 3GPP LTE protocol standard does not specify how to allocate user downlink resources, that is, which users are allocated time-frequency resources in the transmission time interval, and how many resources are allocated to users. However, reasonable downlink resource allocation affects the capacity and coverage of broadband wireless communication systems. and key elements of business quality

Abstract

The invention discloses an LTE system base station device downlink resource distribution method and device. The LTE system base station device downlink resource distribution method includes the steps that based on a wideband channel quality indicator (CQI), downlink resources are primarily and secondarily distributed, and the downlink resources are distributed based on a sub-band CQI. Configuration of various system parameters in an LTE system is fully considered, the parameters include channel quality information of users, service features, the service data buffer data size and the user control information buffer data size, the resources are distributed to the system access users, the requirements for QoS of different services of the system access users can be effectively guaranteed, and meanwhile system spectrum efficiency is improved.

Description

technical field [0001] The present invention relates to the related technical field of base station design in a mobile communication system, in particular to a method and device for allocating downlink resources of base station equipment in an LTE system. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) project is the evolution of the third-generation mobile communication technology. It improves and enhances the 3G air access technology. The physical layer uses OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-Input Multiple- Output) technology, which can provide a peak rate of 150Mbit / s downlink and 75Mbit / s uplink under a 20MHz spectrum bandwidth. At the same time, the performance of cell edge users is further improved, cell capacity is increased and system delay is reduced. [0003] In the LTE system, the downlink resource allocation is realized by the base station equipment in a centralized control mode. Each base stati...
