A kind of control method for transmitting signaling and system

Technical field

The present invention relates to OFDM (OFDM, Orthogonal Frequency Division Multiplexing) technology, be meant a kind of control method for transmitting signaling and system especially.

Background technology

Along with the development of mobile Internet and popularizing of smart mobile phone, people rapidly increase the mobile data flow requirements, and simultaneously, the data business volume that increases has fast proposed severe challenge to the transmittability of mobile communications network.According to the prediction of authoritative institution, in following 10 years, that is: 2011-2020, the mobile data services amount is also doubled every year, will increase by 1,000 times in 10 years.

Most mobile data services mainly occur in indoor and the focus environment, are presented as that nomadic/local wireless inserts scene.According to statistics, at present nearly 70% in the mobile data services amount occurs in indoorly, and this ratio also will continue to increase, and expecting 2012 will surpass 80%.Data service is mainly Internet service, and in other words, data service is mainly Internet protocol (IP, Internet Protocol) data packet traffic, and is therefore more single to the requirement of service quality, and far below the requirement of conventional telecommunications business to service quality.Because cell mobile communication systems mainly is to design to the conventional telecommunications of high-speed mobile, seamless switching is professional; So; When it carries big flow low speed IP data packet traffic; Can there be the problem that efficient is on the low side, cost is too high, so, just need special solution be provided for nomadic/local wireless data insert scene.

At present; The existing solution that is fit to the data traffic transmission of nomadic/local wireless data access scene mainly comprises: (the IEEE of IEEE; Institute of Electrical and Electronics Engineers) 802.11 series standards and ultrahigh speed throughput of future generation (NUHT, Next Ultra-High Throughout) standard.Wherein, what the NUHT standard adopted is the OFDM technology, and the frame structure of configuring time division duplex (TDD, Time Division Duplexing), and the basic parameter of ofdm system can see table 1 for details.

Wherein, [c ₁₅c ₁₄C ₀] _CRCCRC (CRC, the Cyclical Redundancy Check) check code of expression unicast schedule signaling field; [d ₁₁d ₁₀D ₀] the expression base station assigns give 12 unique bit identification of this sub-district at terminal (ID, IDentity);

The expression xor operator.

In ofdm system, need decode to clean culture and the broadcast scheduling signaling that send on CCH the base station in the terminal, and the data according to decoding obtains generate 16 CRC check sign indicating number, and according to formula (1), produce data [b to be verified ₅₆' b ₅₇' ... B ₇₁'], the data [b that relatively decodes and obtain afterwards ₅₆b ₅₇B ₇₁] and data [b to be verified ₅₆' b ₅₇' ... B ₇₁'], if both are consistent, think that then this signaling is the signaling that sends to this terminal, otherwise, think that this signaling is not the signaling that sends to this terminal.

In the prior art; Need decode to whole control signalings in order to obtain to send among the CCH the whole control signalings of self in the terminal, whether compare each signaling according to the method described above then is the signaling that sends to self; Like this, can seriously increase the processing delay at terminal; In addition, also can increase the power consumption at terminal, thereby reduce the time of terminal standby.
