The embodiment of the present invention the 2nd SSS can still adopt m sequence to produce, and production method see 3GPP TS36.211, can repeat no more here.But use and be different from existing m value incidence relation.

Concrete, network equipment determines the m value incidence relation that in the physical layer identifications of community, the first numerical value is corresponding;

Network equipment, according to the corresponding relation of a m value incidence relation and the 2nd m value incidence relation, determines the 2nd m value incidence relation that a m value incidence relation is corresponding;

Network equipment, according to the 2nd m value incidence relation determined, determines the 2nd SSS in the second synchronizing signal that community is corresponding.

The physical layer identifications of You Yige community, each community, each physical layer identifications is made up of the first numerical value and second value, and the first numerical value in the physical layer identifications of each community can corresponding m value incidence relation (m ₀, m ₁).Such as table 2 is exactly the corresponding relation of the first numerical value in the physical layer identifications of community and m value incidence relation.

Table 2

It should be noted that, in the physical layer identifications of embodiment of the present invention community, the corresponding relation of the first numerical value and first index is not limited to the content of table 2, and other corresponding relations are suitable for the embodiment of the present invention too.

The corresponding relation of embodiment of the present invention setting the one m value incidence relation and the 2nd m value incidence relation, a m value incidence relation can be determined according to the first numerical value in the physical layer identifications of this community, corresponding relation according to a m value incidence relation and the 2nd m value incidence relation just can determine the 2nd m value incidence relation, last according to the 2nd m value incidence relation, adopt m sequence just to obtain the 2nd SSS.

Accordingly, subscriber equipment is after searching the 2nd SSS, the 2nd m value incidence relation just can be determined according to the 2nd SSS, according to the corresponding relation of a m value incidence relation and the 2nd m value incidence relation, just can determine the m value incidence relation that the 2nd m value incidence relation is corresponding, then according to the corresponding relation of the first numerical value in physical layer identifications and a m value incidence relation, the first numerical value in the physical layer identifications of community can just be determined.

One m value incidence relation of embodiment of the present invention setting and the corresponding relation of the 2nd m value incidence relation can be notified by high level, also can specify in the protocol.Regardless of what mode, as long as ensure to understand unanimously between network equipment and subscriber equipment.

Determine the 2nd SSS mode two:

Similar with mode one, but the method obtaining m value incidence relation is different from mode one.

Concrete, network equipment, according to the corresponding relation of the first numerical value in physical layer identifications and the 2nd m value incidence relation, determines the 2nd m value incidence relation that the physical layer identifications of community is corresponding;

The physical layer identifications of You Yige community, each community, first numerical value and the 2nd m value incidence relation in embodiment of the present invention setting physical layer identifications, the 2nd m value incidence relation can be determined according to the first numerical value in the physical layer identifications of this community, according to the 2nd m value incidence relation, m sequence is adopted just to obtain the 2nd SSS.

Accordingly, subscriber equipment is after searching the 2nd SSS, the 2nd m value incidence relation just can be determined according to the 2nd SSS, according to the corresponding relation of the first numerical value in physical layer identifications and the 2nd m value incidence relation, the first numerical value in the physical layer identifications of the community that the 2nd m value incidence relation is corresponding just can be determined.

In the physical layer identifications of embodiment of the present invention setting, the corresponding relation of the first numerical value and the 2nd m value incidence relation can be notified by high level, also can specify in the protocol.Regardless of what mode, as long as ensure to understand unanimously between network equipment and subscriber equipment.

Determine the 2nd SSS mode three:

Network equipment carries out scrambling or cyclic shift to the SSS in the first synchronizing signal corresponding to community, obtains the 2nd SSS in the second synchronizing signal corresponding to community;

Accordingly, subscriber equipment is after searching the 2nd SSS, descrambling or cyclic shift are carried out to the 2nd SSS, obtain a SSS, then first corresponding index can just be determined according to a SSS, according to the corresponding relation of physical layer identifications and first index, the physical layer identifications of community just can be determined.

The running time-frequency resource taken when two, determining transmission the second synchronizing signal.

In force, the running time-frequency resource taken when sending the first synchronizing signal and the running time-frequency resource taken when sending the second synchronizing signal adopt TDM(Time Division Multiple, time division multiplexing) mode and/or FDM(Frequency Division Duplex, frequency division multiplexing) mode is multiplexing.

The running time-frequency resource that the embodiment of the present invention second synchronizing signal takies has two kinds of situations: a kind of is that in the second synchronizing signal, the 2nd PSS is different from the running time-frequency resource that a PSS in a first synchronizing signal and SSS takies with the running time-frequency resource that the 2nd SSS takies; Another kind is that in the second synchronizing signal, the 2nd PSS is identical with the running time-frequency resource that a PSS in the first synchronizing signal takies, but in the second synchronizing signal, the 2nd SSS is different from the running time-frequency resource that a SSS in the first synchronizing signal takies.Be described respectively below.

Situation one, the running time-frequency resource taken when sending the first synchronizing signal are different with the running time-frequency resource taken when sending the second synchronizing signal, and namely in the second synchronizing signal, the 2nd PSS is different from the running time-frequency resource that a PSS in a first synchronizing signal and SSS takies with the running time-frequency resource that the 2nd SSS takies.

Wherein, the running time-frequency resource taken when sending the first synchronizing signal and the running time-frequency resource taken when sending the second synchronizing signal adopt TDM mode multiplexing, comprising:

The frequency taken when sending the first synchronizing signal is identical with the frequency taken when sending the second synchronizing signal, and the time domain taken when sending the first synchronizing signal is different with the time domain taken when sending the second synchronizing signal.

Concrete, the OFDM(OrthogonalFrequency Division Multiplexing taken when sending the PSS in the first synchronizing signal, OFDM) symbol is different with the OFDM symbol taken during the 2nd PSS sent in the second synchronizing signal, and the OFDM symbol taken when sending the SSS in the first synchronizing signal is different with the OFDM symbol taken during the 2nd SSS sent in the second synchronizing signal.

For FDD-LTE system, an one PSS and SSS latter two OFDM symbol respectively in first time slot in the subframe 0 and subframe 5 of each radio frames sends, then the 2nd PSS and the 2nd SSS can remove existing PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel), PBCH(Physical Broadcast Channel, Physical Broadcast Channel) and an a PSS and SSS outside other symbols send, such as in first time slot in the subframe 0 and subframe 5 of each radio frames the first two OFDM symbol send.

Wherein, the running time-frequency resource taken when sending the first synchronizing signal and the running time-frequency resource taken when sending the second synchronizing signal adopt FDM mode multiplexing, comprising:

The frequency taken when sending the first synchronizing signal is different with the frequency taken when sending the second synchronizing signal.

Concrete, the subcarrier taken when the subcarrier taken when sending the PSS in the first synchronizing signal and the 2nd PSS sent in the second synchronizing signal is different, and the subcarrier taken when sending the SSS in the first synchronizing signal is different with the subcarrier taken during the 2nd SSS sent in the second synchronizing signal.

Such as the 2nd PSS and the 2nd SSS take 6 PRB(physicalresource block except LTE system bandwidth central authorities, Physical Resource Block) outer other PRB.

Preferably, if have frequency division multiplexing relation between the running time-frequency resource taken when sending the first synchronizing signal and the running time-frequency resource taken when sending the second synchronizing signal, the centre frequency of the frequency resource taken when sending the second synchronizing signal is the non-integral multiple of setting numerical value.

Such as setting numerical value is 100, then the centre frequency of the frequency resource taken when sending the second synchronizing signal is not the integral multiple of 100, such as

The centre frequency sending the frequency resource that the 2nd PSS in the second synchronizing signal and the 2nd SSS takies is 1.08MHz, 2.16MHz...... at a distance of system bandwidth centre frequency.

The object done so mainly makes the subscriber equipment of 3GPP R11 and former LTE protocol can not receive the second synchronizing signal, this is because the subscriber equipment of 3GPP R11 and in the past LTE protocol carries out Cell searching based on the first synchronizing signal, and the centre frequency that the first synchronizing signal takies is system centre frequency, and system centre frequency is the integral multiple of 100KHz.

Another benefit done like this is, if 3GPP LTE R12 and subscriber equipment there is no the configuration information of acquisition second synchronizing signal (such as such subscriber equipment is in the idle(free time) state and there is no the configuration information of the second synchronizing signal), Cell searching can only be carried out based on the first synchronizing signal, such subscriber equipment also can be avoided may to carry out Cell searching based on the second synchronizing signal in such cases.

In force, the running time-frequency resource that the 2nd PSS and the 2nd SSS of different districts take can be identical, also can be different.When being positioned on different running time-frequency resources, similarly, the 2nd PSS of different communities and the 2nd SSS can adopt the mode of above-mentioned TDM and/or FDM.

Situation two, the running time-frequency resource taken when sending the first synchronizing signal are different with the running time-frequency resource part taken when sending the second synchronizing signal, namely in the second synchronizing signal, the 2nd PSS is identical with the running time-frequency resource that a PSS in the first synchronizing signal takies, but in the second synchronizing signal, the 2nd SSS is different from the running time-frequency resource that a SSS in the first synchronizing signal takies.

Wherein, the running time-frequency resource taken when sending the first synchronizing signal is different with the running time-frequency resource part taken when sending the second synchronizing signal, comprising:

The running time-frequency resource taken when the running time-frequency resource taken when sending the PSS in the first synchronizing signal and the 2nd PSS sent in the second synchronizing signal is identical;

Sending running time-frequency resource that the SSS in the first synchronizing signal takies and sending the running time-frequency resource that the 2nd PSS in the second synchronizing signal takies adopts TDM mode multiplexing, wherein running time-frequency resource adopt TDM mode to be multiplexed with in transmission first synchronizing signal a SSS time frequency that takies and send in the second synchronizing signal the 2nd SSS time the frequency that takies identical, and the time domain taken during the 2nd SSS in the time domain taken when sending the SSS in the first synchronizing signal and transmission the second synchronizing signal is different.

Concrete, the frequency taken when the frequency taken when sending the SSS in the first synchronizing signal and the 2nd SSS sent in the second synchronizing signal is identical, and the time domain taken during the 2nd SSS in the time domain taken when sending in the first synchronizing signal a SSS and transmission the second synchronizing signal is different, comprising:

The OFDM symbol taken when the OFDM symbol taken when sending the PSS in the first synchronizing signal and the 2nd PSS sent in the second synchronizing signal is identical, and the subcarrier taken when sending the PSS in the first synchronizing signal is identical with the subcarrier taken during the 2nd PSS sent in the second synchronizing signal;

The OFDM symbol taken when the OFDM symbol taken when sending the SSS in the first synchronizing signal and the 2nd SSS sent in the second synchronizing signal is different.

Sending running time-frequency resource that the SSS in the first synchronizing signal takies and sending the running time-frequency resource that the 2nd PSS in the second synchronizing signal takies adopts FDM mode multiplexing, wherein running time-frequency resource adopt FDM mode to be multiplexed with in transmission first synchronizing signal a SSS time time domain that takies and transmission the second synchronizing signal in the 2nd SSS time the frequency that takies different.

Concrete, the frequency taken when the time domain taken when sending the SSS in the first synchronizing signal and the 2nd SSS sent in the second synchronizing signal is different, comprising:

The subcarrier taken when the subcarrier taken when sending the SSS in the first synchronizing signal and the 2nd SSS sent in the second synchronizing signal is different.

Such as the 2nd PSS and the 2nd SSS take other the PRB except 6 PRB of LTE system bandwidth central authorities.

For in above-mentioned two situations, the running time-frequency resource taken when sending the PSS in the first synchronizing signal and the first relativeness of running time-frequency resource taken when sending in the first synchronizing signal a SSS, can be the same or different with the running time-frequency resource taken during the 2nd PSS in transmission second synchronizing signal and the second relativeness of running time-frequency resource of taking when sending in the second synchronizing signal the 2nd SSS.

If the first relativeness and the second relativeness are sending order, and if method is applied to TDD-LTE system or method is applied in FDD-LTE system, then the second relativeness is first send after the 2nd PSS to send the 2nd SSS.Such as, the 2nd PSS and the 2nd SSS can be OFDM symbol shared by the foremost of OFDM symbol shared by the 2nd SSS signal, the 2nd PSS backmost.

If the first relativeness and the second relativeness can be mark space, then the OFDM symbol shared by PSS signal of the OFDM symbol shared by PSS signal of the 2nd PSS and the 2nd SSS and the mark space between the OFDM symbol shared by SSS and the 2nd PSS and the 2nd SSS and the mark space between the OFDM symbol shared by SSS can be the same or different.

Preferably, when OFDM symbol shared by the PSS signal of the OFDM symbol shared by PSS signal of the 2nd PSS and the 2nd SSS and the mark space between the OFDM symbol shared by SSS and the 2nd PSS and the 2nd SSS is different with the mark space between the OFDM symbol shared by SSS, there are two kinds of implementations:

The mark space of shared symbol when implementation one, first relativeness and the second relativeness are shared symbol and transmission SSS when sending PSS:

If method is applied to TDD-LTE system, first relativeness be when sending PSS in the TDD-LTE system specified in 3GPP LTE protocol version 11 and version before shared symbol and send SSS time shared symbol mark space, shared by the symbol namely in the mark space of the 2nd PSS and the symbol shared by the 2nd PSS signal in the 2nd SSS and symbol shared by the 2nd SSS and existing TDD-LTE system in an a PSS and SSS shared by a PSS signal and a SSS, the mark space of symbol is different;
