Embodiment
In order to make those skilled in the art person understand better the scheme of the embodiment of the present invention, below in conjunction with drawings and embodiments, the embodiment of the present invention is described in further detail.
Because the band resource of a LTE-A system is aggregated into the sightless band resource of LTE system by the band resource of a plurality of LTE systems and some, therefore the embodiment of the present invention arranges several main carrier frequencies on the LTE-A band system band, and all the other carrier waves are auxiliary carrier wave.Send synchronizing signal and the broadcast message of LTE-A system on the main carrier frequency, the broadcast message of LTE-A system comprises the system information of the initial random access of each carrier wave of system, the LTE-A system user can be identified these signals, to the LTE system user, is sightless.Thereby realize the configuration of LTE-A system BCH and SCH, make the LTE-A system customer equipment can be efficiently, connecting system rapidly.
Further, synchronizing channel and broadcast channel by configuration LTE system on the center of discernible each discrete frequency bands resource of LTE system user, thereby can make two kinds of systems compatible mutually, in order to can support the terminal use's of various different brackets access, and the co-channel interference of the many minizones can suppress to access well the time.
As shown in Figure 1, be the synchronizing channel of LTE-A system in the embodiment of the present invention and the configuration schematic diagram of broadcast channel:
As can be seen from the figure, the BCH of LTE-A system and SCH are disposed on the frequency ranges of data of LTE system, therefore in this case for fear of issuable interference between two systems, the running time-frequency resource of the SCH corresponding to the LTE-A system in the LTE system and BCH is put to sky, unavailable.In like manner, will in the LTE-A system, corresponding to the SCH of LTE system and the running time-frequency resource of BCH, put sky, so just can avoid two kinds of interference between system.
The main carrier synchronizing channel of neighbor cell is configurable, to avoid the co-channel interference in initial access process.The main carrier synchronizing channel of all LTE-A user Dou Cong community is carried out initial down-going synchronous, read broadcast message from broadcast channel, complete random access according to initial random access information, then according to the ability of self and the system information indication of community, jump to working frequency range, make the community subscriber equipment of compatible different performance well.After subscriber equipment enters working frequency range, can use pilot tone synchronously to correct, as need read broadcast message, will jump to the main carrier receiving broadcasting information.
Synchronizing channel on the main carrier frequency (LTE-A PSCH) is for guaranteeing subscriber equipment capture systems and identification community rapidly and accurately: following functions mainly is provided: down time-frequency synchronization is caught, and identifies different communities.The synchronizing signal of LTE-A PSCH should have good autocorrelation performance, and different from the synchronizing signal of LTE system, and its signal is only relevant to a few or an operator, structure that like this can simplified receiver.The synchronizing time point that the due in of most powerful path of take is primary synchronization channel.
Broadcast channel on the main carrier frequency is for sending all and broadcast message System Dependent, such as the common channel information of the uplink random access at the loading condition of system bandwidth, each work carrier wave, main carrier frequency place etc., to meet the various work requirements of LTE-A system user.
The visible synchronizing channel of LTE system and the broadcast channel of other frequencies, for sending synchronizing signal and the public broadcasting message of LTE system, and the distinctive broadcast message of this frequency range, as Random Access Channel (RACH) information relevant with this frequency, indicate the time-frequency resource allocating information of initial uplink access channel in this carrier wave, and dynamic broadcast information, to meet the various work requirements of LTE system user.
