A METHOD AND DEVICE FOR DOWNLINK DATA TRANSMISSION

摘要

A method for downlink data transmission is provided, a terminal reports the terminal grade that itself supports and the extended memory indication for denoting the terminal memory size to the base station; the base station obtains the maximum number N of processes supported by downlink according to the proportion of uplink and downlink; according to the terminal grade, the extended memory indication and the maximum number N of processes supported, the base station performs the pre-operation of the memory allocation and the downlink transmission. An user terminal and a base station are also provided. Through the invention, the base station can pertinently adopt the way of memory allocation to allocate the UE memory, and it is avoid that the matched rate of the effective rate approximates to or exceeds 1, and the transmission reliability of the system is improved.
