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 a method and device for allocating downlink resources of base station equipment in an LTE system. The method for allocating downlink resources for base station equipment in an LTE system of the present invention includes performing primary and secondary resource allocation on downlink resources based on a broadband CQI (Channel quality indicator, channel quality indicator). Resource pre-allocation, allocating downlink resources based on subband CQI. The present invention fully considers various system parameter configurations in the LTE system, including user channel quality information, service characteristics, service data buffer data volume, and user control information buffer data volume to allocate resources for system access users, which can effectively Guarantee the QoS requirements of different services of system access users and improve the spectrum efficiency of the system at the same time.

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 the 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 sta...
