Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method, system and device of message transmission.
Background technology
(the International Telecommunication Union of International Telecommunications Union, ITU) (International Mobile Telecommunications-Advanced, performance IMT-Advanced) has proposed very harsh requirement to next generation mobile communication system.While has also proposed very high requirement to average spectral efficiency (ase), especially the edge spectrum efficiency of system.Therefore, in order to satisfy the requirement of ITU to the IMT-Advanced system, third generation partner program (3rd Generation Partnership Project, 3GPP) at its mobile cellular communication (Long Term Evolution-Advanced of system of future generation, LTE-Advanced) in, proposed to adopt multi-point cooperative transmission technology and high-order mimo technology to improve the scheme of systematic function.
(the User Equipment of terminal in the LTE system, UE) can estimate the channel information of base station according to the public guide frequency port of sub-district to this UE, the calculating channel quality is indicated (Channel Quality Indicator in view of the above, CQI) information, and the CQI that calculates fed back to the base station, with also may comprising that this CQI together feeds back: the index of pre-coding matrix (Precoding Matrix Indicator, PMI) and number of data streams (Rank Indicator, RI).When the base station receives the CQI that UE feeds back, just can carry out the scheduling of sub-district, distribution and modulation and coding (Modulation and Coding Scheme, the operations such as selection MCS), thereby the raising availability of frequency spectrum of resource.
The public guide frequency of LTE system both can be used for the estimation of CQI, PMI and RI, also can be used for the demodulation of data.(Multiple Input Multiple Output, MIMO) under the technology, for being used for the purpose that CQI, PMI and RI estimate, the pilot density of LTE system port 0～3 has redundant high-order multiple-input and multiple-output in the LTE-Advanced system.For supporting the high-order mimo transmission, in the LTE-Advanced system, need to increase new antenna port, for example this port that increases newly is designated as port 4～7 (port numbers that writes in the last standard not necessarily 4～7).If the pilot density of port 4～7 is according to the density setting of LTE system port 0～3, its expense is unacceptable.The demodulation pilot frequency that is divided into more low-density CQI measurement pilot frequency and higher density because of the pilot tone of LTE-A system.
Simultaneously, in the multi-point cooperative transmission technology, when a plurality of sub-districts simultaneously when an edge UE sends data, this edge UE need estimate the channel of these a plurality of sub-districts.Because there is frequency shift in the setting of LTE system downlink pilot between the neighbor cell public guide frequency at present, therefore, can avoid the phase mutual interference between the district pilots, but the interference between inevitable data and the pilot tone.And, in the multi-point cooperative transmission technology, need to increase new pilot tone in order to guarantee the estimated accuracy of CQI, PMI and RI, also be divided into the demodulation pilot frequency of more low-density CQI measurement pilot frequency and higher density.
When the LTE-Advanced system for supporting in the high-order mimo technology or multi-point cooperative transmission technology when increasing new CQI measurement pilot frequency, need compatible LTE R8 user, promptly the new public guide frequency of Zeng Jiaing should not influence LTE R8 user's Traffic Channel, needs to guarantee channel estimated accuracy simultaneously.In addition, the UE that receives information when the network equipment some in the LTE-Advanced system sends control signaling or can not compatible LTE R8 during information such as data, may LTE R8 user's Traffic Channel be impacted, thereby influences its reliability of information transmission.
