Problems solved by technology

However, in the case of high-speed travel of the user equipment, such interpolation will deteriorate the accuracy of channel estimation, because the two time slots on the same antenna are not consecutive, and the time correlation between the channels experienced by the two time slots is very Low

Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to avoid confusing the understanding of the present invention.

[0022] figure 2 A structural block diagram of baseband processing of a mobile terminal according to an embodiment of the present invention is shown. Such as figure 2 As shown, two transmit antennas 190 and 200 are provided in a packet-based MIMO single carrier frequency division multiplexing system for the purpose of clarity. The user equipment sends a subframe containing two slots to the Node B, and each slot has 7 long blocks. The long block in the middle of each slot is reserved for inserting pilots. According to the mobile terminal of the embodiment of the present invention, the turbo encoder 110 performs turbo encoding on the data to be transmitted, and then the modul...

Abstract

A multi-antennae mobile terminal and method for transmitting information frames in a multi- antennae communication system. The method includes: dividing each of the several information frames which are to be transmitted into several segments; transmitting the last segment of current information frame and the first segment of the next information frame on the same emission antenna.

Description

technical field [0001] The invention relates to a mobile terminal with multiple antennas and a method for sending information frames in a multi-antenna communication system, which can improve the accuracy of base station (Node B) side channel estimation when the mobile terminal moves at high speed. Background technique [0002] In order to ensure the competitiveness of 3G technology in the future, the 3rd Generation Partnership Project (3GPP) has started the Long Term Evolution (LTE) of the 3G cellular system. It is currently believed that an evolved link layer capable of supporting advanced multi-antenna solutions and an OFDM-based radio access technology are very useful for the realization of these goals. For the uplink of LTE, single carrier frequency division multiple access technology can provide a larger coverage because of its higher power efficiency. [0003] In order to reduce the complexity of the user terminal, LTE Release 8 stipulates that the uplink adopts a tr...
