Description

A kind of data transmission method and equipment

Technical field

The present invention relates to field of communication technology more particularly to a kind of data transmission method and equipment.

Background technique

As a kind of novel communication theory, the purpose is to will be more for machinery compartment (M2M, Machine-to-machine) communication The different types of communication technology of kind organically combines, such as: machine-to-machine communication, human-computer interaction communication, is moved at apparatus control communication Dynamic interconnected communication, to push social production and the development of life style.It is expected that the business of following Human To Human's communication may be accounted for only The 1/3 of entire terminal market, and greater amount of communication is machinery compartment (small bandwidth system) communication service.

Current mobile communications network for interpersonal communication scheme, such as: the determination etc. of network capacity. If it is desired to which small bandwidth system communication is supported just to need according to the characteristics of small bandwidth system communication pairs using mobile communications network The mechanism of mobile communication system optimizes, so as to communicate on traditional person to person not by or by smaller the case where influencing Under, small bandwidth system communication is better achieved.

The MTC communication being currently recognized that some characteristics that may be present have:

Machine-type communication (MTC, Machine Type Communications) terminal has Hypomobility；

The time that MTC terminal and network side carry out data transmission is controllable；I.e. MTC terminal can only be when network be specified Between accessed in section.

MTC terminal transmits data with the data transmission that network side carries out not high to requirement of real-time, it may be assumed that there is the time to hold Bearing property；

MTC terminal energy constraint, it is desirable that extremely low power consumption；

The information transmission of small data quantity is only carried out between MTC terminal and network side；

MTC terminal can be managed as unit of group.

One actual MTC terminal can have above-mentioned one or more characteristics.

The coverage enhancement technology introduction of M2M transmission is as follows:

Technology of Internet of things is in the ascendant, in 3-G (Generation Three mobile communication system) and its long evolving system (LTE, Long Term Evolution) in need support MTC function.One MTC device (or MTC terminal) may have a variety of M2M communications Part of properties among characteristic, such as: Hypomobility, transmitted data amount be small, it is insensitive to communication delay, require extremely low power dissipation etc. Feature.

Global system for mobile communications (GSM, Global System for Mobile is based on existing Communication) in the M2M network of technology, operator finds the terminal to work under some scenes, for example works in underground Room, market or the terminal for building corner, since wireless signal is seriously blocked, signal is by very big decaying, above-mentioned terminal Can not be communicated with network, and for the depth covering that network is carried out under these scenes can greatly increase the networking of network at This.Operator is by test, it is believed that needs just meet the existing coverage enhancement such as 15dB of GSM the covering need of above-mentioned scene It asks.Subsequent long term evolution (LTE, Long Term Evolution) technology can substitute GSM and transmit for M2M, due to LTE and GSM Covering is substantially suitable, and therefore, LTE technology is also required to the covering of enhancing such as 15dB and wants to meet the transmission of the M2M under above-mentioned scene It asks.

Accomplish the coverage enhancement of 15dB, a kind of more feasible method is needed to LTE system existing channel using weight Multiple transmission or similar techniques, theoretically can be by repeating transmission acquisition to the progress of existing physical channel tens times to several hundred times The covering gain of 15dB.

The prior art realizes coverage enhancement using the method for repeat mechanism, needs to occupy more channel resource, reduces Efficiency of transmission increases power consumption of terminal, in addition, same time-frequency domain resources are only used for the repetition transmission of a user, reduces System multiplexing capacity.In order to solve above-mentioned drawback, it is also contemplated that using based on physical uplink control channel (Physical Uplink Control Channel, PUCCH) structural transmission transmission block (TB, Transport Block), passes through channel for TB Encoded infonnation after coding (may include rate matching procedure) is divided into multiple subframes, is all based in each subframe PUCCH structural transmission.On the other hand, in order to reduce number of repetition as far as possible, after study, it is found that cross-subframe channel estimation is one The effective means of kind.So-called cross-subframe channel estimation, refer to using in multiple subframes reference signal carry out joint channel estimation, A kind of typical processing mode is that the result for estimating multiple sub-frame chan-nels is weighted and averaged.Correspondingly, the number of multiple subframes According to partially carrying out relevant merging.And it is identical that relevant combined premise, which is the signal sent in the multiple subframes for being used to merge, 's.But since bearer cap of the PUCCH structure in a subframe is limited, the information after TB coding needs to be divided into multiple It is transmitted in subframe, causes the information transmitted in different subframes different, relevant merging can not be carried out.

In conclusion the prior art is estimated during transmitting terminal and receiving end carry out data transmission using more sub-frame chan-nels Shi Wufa carries out relevant merging, therefore causes the demodulation performance of transmitting terminal and the receiving end receiving end in frequency departure poor.
