Description

Transmission, method of reseptance and the device of information

Technical field

The present invention relates to the communications field, in particular to a kind of transmission of information, method of reseptance and device.

Background technology

In wireless communication system, transmitting terminal and receiving terminal typically can send and receive to obtain higher speed using many antennas. One principle of multiple-input and multiple-output (multiple-input-multiple-output, referred to as MIMO) technology utilizes channel Some features form the multilayer transmission of match channels feature, so as to obtain notable without increase on the basis of bandwidth and power Performance boost, the extensive use in current system.Such as at Long Term Evolution (Long Term Evolution, referred to as LTE) Strengthen with it has in version (enhanced Long Term Evolution (Long Term Evolution-Advanced, referred to as LTE A)) system The pattern of a variety of multi-antenna technology transmission, transmission mode 2 is space-frequency diversity, and transmission mode 3 is Open-Loop Spatial Multiplexing or is to open Ring MIMO technology, transmission mode 4 is Closed-Loop Spatial Multiplexing, and transmission mode 5 is multiuser MIMO, and transmission mode 6 is single The Closed-Loop Spatial Multiplexing of data flow, transmission mode 7 and 8 is respectively single current and dual-stream beamforming, and transmission mode 9 is supported most Big 8 layers of spatial reuse, and the adaptive switching as user and multi-user can be realized, the adaptive switching of the data number of plies is supported Open loop MIMO and closed-loop MIMO pattern.

In these transmission modes, user feedback precoding matrix indicators (Precoding Matrix Indicator, letter the need for having Referred to as PMI), referred to as closed-loop MIMO techniques, what is had need not feed back PMI, referred to as open loop MIMO techniques.LTE/LTE A Defined in these transmission modes, primarily to adapt to different user channel characteristics and user receiving ability.Such as 1 It can only use the MIMO technology that the multiplexing number of plies is 1 to the user of root reception antenna, and channel variation is than faster user, Ke Yikao Consider the MIMO technology using open loop because user moving speed than it is very fast when, the change of channel is than very fast, in feedback week In phase, descending letter in the next feedback cycle in reflection base station that the precoding information that Closed-Loop Spatial Multiplexing feeds back can not be accurately and timely Road information, so that the decline of performance can be caused.And Open-Loop Spatial Multiplexing technology is due to that need not feed back precoding information, with more Good robustness.

LTE/LTE A earlier version such as Release 8/Release 9 are using based on cell common reference signal (Cell-specific Reference Signal, referred to as CRS) open loop MIMO, it is realized using TM3, and demodulation is main considers It is demodulated using CRS method.Because CRS maximums support 4 ports, so TM3 does not support the situation more than 4 ports.

As the sending port that base station is configured is more and more, the open loop MIMO techniques of more multiport are supported to be also required to be supported, In LTE/LTE A release 10 and later version, transmission mode 9 and transmission mode 10 are defined, it can be based on solution Reference signal (Demodulation Reference Signal, referred to as DMRS) is adjusted to do open loop MIMO.Based on DMRS Open loop MIMO in, because terminal will not feed back precoding information, so base station does not have the information of priori to be determined at descending Data are transmitted in the precoding matched somebody with somebody, so as to cause hydraulic performance decline because precoding is inaccurate, particularly based on multiple PRB granularities Open-loop precoding situation, once selection precoding it is bad, then easily cause the bust this of whole data block, a kind of method It is that Physical Resource Block (Physical Resource Block, referred to as PRB) is divided into multiple resource unit groups exactly by one (Resource Element Group, referred to as REG), each REG uses a precoding using independent, so as to effective Ground travels through different code words to improve the performance of system.The REG described here is to include N number of OFDM/OFDMA Symbol resource unit RE corresponding with M subcarrier set, gathers the RE in resource unit group in same PRB pair, RE in REG can be continuous or discrete.
