Embodiment Construction

[0039] In the embodiment of the present invention, the terminal determines the channel estimation window assigned to itself by the base station, and performs channel estimation according to the determined channel estimation window, and performs channel estimation according to the channel estimation window used by itself when it is determined that other terminals perform space division multiplexing with itself. As a result, the received data is demodulated, so that the SDMA technology can be used for data transmission in the single-stream mode of the TDDHSPA+ system, and the data transmission rate is improved.

[0040] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] Such as figure 1 As shown, the system for processing data in the high-speed packet access evolution system according to the embodiment of the present invention includes a base station 10 and a terminal 20 .

Abstract

The invention relates to the field of wireless communication, in particular to a method, a system and a device for treating data in a high-speed packet access evolution system, which are used for adopting an SDMA (Space Division Multiple Address technology) in a uniflow mode of TDD (Time Division Duplex) HSPA (High Speed Packet Access) and the system. In the method, a terminal determines a channel estimation window allocated to the terminal by a base station and carries out channel estimation according to the determined channel estimation window; the terminal carries out activity detection on the result obtained by channel estimation and determines the channel estimation window used per se from the channel estimation windows allocated to the terminal by the base station; and the terminal demodulates the received data according to the result obtained by the channel estimation through the channel estimation window used per se and the quantity of other terminals for space division multiplexing per se. By adopting the embodiment of the invention, the transmission speed of the data and the throughout and the capacity of the system can be increased.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, system and device for processing data in a high-speed packet access evolution system. Background technique [0002] SDMA (Space Division Multiple Access, Space Division Multiple Access) technology is to distinguish multiple terminals occupying the same resource using the spatial degrees of freedom provided by multiple antennas, so as to realize data transmission and reception of multiple terminals. [0003] In the current HSPA+ (High Speed ​​Packet Access plus: High Speed ​​Packet Access Evolution) system, downlink terminals use two transmission methods: single-stream transmission and dual-stream transmission. When the user cannot satisfy the requirement of sending dual-stream data, it switches to single-stream. [0004] Single-stream transmission means that one data stream is used to transmit data between the terminal and the base station; dual-stream transmissio...
