Abstract

The invention discloses an uplink data receiving processing method and device. The method comprises the steps that after received uplink data are subjected to OFDM processing, data of a first user equipment group and data of a second user equipment group are separated from the uplink data by equilibrium processing; following processing of the data of the first user equipment group and the data of the second user equipment group is divided into a plurality of processing procedures, a first processing procedure is carried out on the data of the first user equipment group, then a next processing procedure is carried out on the data of the first user equipment group, and meanwhile a previous processing procedure is carried out on the data of the second user equipment group, until all the processing procedures are carried out on the data of the first user equipment group and the data of the second user equipment group respectively, and physical layer data of the first user equipment group and physical layer data of the second user equipment group are obtained. According to the uplink data receiving processing method and device, the utilization rate of an inner hardware circuit of an LTE uplink receiver supporting a Turbo-SIC is improved.

Description

technical field

[0001] The present invention relates to the communication field, in particular, to a method and device for receiving and processing uplink data. Background technique

[0002] With the rapid development of mobile services, the demand for mobile network capacity is also increasing significantly. Due to the adoption of Orthogonal Frequency Division Multiplexing (OFDM) technology and Multiple Input Multiple Output (MIMO) technology, Long Term Evolution (LTE) has greatly improved The capacity of the wireless communication system is increased. But at the same time, due to the introduction of the above-mentioned technologies, the realization of the LTE receiver tends to be complicated. Especially in a complex wireless network environment, in order to solve the problem of signal interference between multiple users, related technologies have introduced: least square (LS), linear minimum mean square error (LMMSE) and serial interference cancellation (Turbo -SIC) and ...
