METHOD AND DEVICE FOR IMPLEMENTING BASEBAND RESOURCE POOL IN LTE BASE STATION

摘要

In a method for implementing a baseband resource pool in an LTE base station provided in the present invention, the LTE base station includes a main control module, a master board, and a slave board, and the master board and the slave board include baseband processing modules. First, the main control module configures information about a cell requiring load sharing on the master board to the slave board; then, the main control module modifies PRACH configuration parameters of the cell according to baseband processing capability of the LTE base station and configures an RACH resource allocation policy; at last, the master board and the slave board perform PRACH detection in a time division or frequency division mode according to the RACH resource allocation policy; or the master board and the slave board respectively detect different preamble root sequences according to the RACH resource allocation policy, and then the master board and/or the slave board detects a preamble; or the slave board detects a PRACH of the cell according to the RACH resource allocation policy. In the method for implementing a baseband resource pool in an LTE base station provided in the present invention, the RACH processing capability of the LTE base station is improved by adding a slave baseband board including a baseband processing module.
