Mode 2: determine to the frequency pattern in described subscriber equipment according to pre-configured.Such as, frequency pattern be pre-configured in subscriber equipment or by protocol conventions, subscriber equipment is pre-configured to the information acquisition frequency pattern in this subscriber equipment according to this.
Mode 3: the frequency pattern that subscriber equipment autonomous configuration is used.Such as, when subscriber equipment configures frequency pattern used according to the strategy of setting, subscriber equipment can select frequency pattern used randomly from available frequency pattern, or, the frequency hopping formula that subscriber equipment is corresponding according to some D2D gain of parameter frequency patterns, thus determine frequency pattern used.Such as obtain frequency pattern according to the D2D relevant parameter such as D2D source ID (SourceID), D2D synchronisation source ID (SynchronizationSourceID), Target id (TargetID), communication set ID (GroupID) of oneself.
In step 102, subscriber equipment sends synchronizing signal by synchronizing channel and carries out channel synchronization.Such as, in D2D transmitting procedure, described synchronizing channel is that physical equipment arrives device synchronization channel (PhysicalDevicetoDeviceSynchronizationChannel, PD2DSCH).Usually, subscriber equipment, before carrying out signal transmission, first will carry out channel synchronization.Subscriber equipment obtains the reference synchronization sending signal according to the synchronizing signal sent with reference to synchronisation source.When subscriber equipment sends signal, also can send synchronizing signal for other subscriber equipmenies provides reference synchronization simultaneously, or simultaneously transfer synchronous channel is to transmit some resource allocation informations or synchronizing information, carry out transmission or the reception of synchronous or signal for other subscriber equipmenies auxiliary.
In this enforcement, repetition transmission of configuration information can be sent by synchronizing channel by subscriber equipment.
Preferably, in step 103, described subscriber equipment carries out signal transmission according to described repetition transmission of configuration information, comprising: the physical resource used when described subscriber equipment determines described Signal transmissions according to described repetition transmission of configuration information, and described physical resource carries out the transmission of described signal.
Preferably, described subscriber equipment can according to as described in determining as one of under type during Signal transmissions the physical resource that uses:
Mode 1: described subscriber equipment according to the iterative transfer times in the repetition transmission of configuration information of described signal and agreement repeat transmit frequency pattern used, determine repeating the physical resource that transmission uses in a transmission cycle except first time at every turn.This mode is applied in repeated configuration information and comprises iterative transfer times but do not comprise the situation repeating to transmit frequency pattern used.
Mode 2: described subscriber equipment transmits the iterative transfer times of frequency pattern used and agreement according to repeating in the repetition transmission of configuration information of described signal, determines that at every turn repeating in a transmission cycle except first time transmits the physical resource used.This mode is applied in repeated configuration information and does not comprise iterative transfer times but comprise the situation repeating to transmit frequency pattern used.

Subscriber equipment obtains except for the first time Signal transmissions according to frequency pattern, when each signal repeats to transmit physical resource used, signal first time transmit physical resource used can be configured by network equipment or subscriber equipment according to setting strategy configuration (such as adopt the mode of Stochastic choice, or obtain based on some D2D parameter of UE), follow-uply repeat to transmit physical resource that physical resource used transmitted by first time and frequency pattern obtains.
Preferably, according to the information that network equipment configures, described subscriber equipment determines that the first time in a described transmission cycle transmits the physical resource used; Or according to the strategy of setting or pre-configured physical resource, described subscriber equipment determines that the first time in a described transmission cycle transmits the physical resource used.
In above-mentioned flow process, in step 102, transmission resource pool information or reception resource pool information can also be sent by synchronizing channel by subscriber equipment together.Subscriber equipment is independently selected in transmission resource pool, to select physical resource during physical resource, and the physical resource that namely subscriber equipment is selected must in the scope sending resource pool.And receiving the situation that resource pool is mainly used in network side configures physical resource, when the physical resource that namely subscriber equipment transmission signal is used is configured by network side, subscriber equipment only needs the subscriber equipment of informing receiving terminal to receive resource pool information.Correspondingly, in step 103, subscriber equipment is selected from transmission resource pool or reception resource pool according to the determined physical resource of repetition transmission of configuration information.Like this, can be on the one hand, signalling subscriber equipment can select physical resource to carry out signal transmission according to repetition transmission of configuration information from described transmission resource pool or reception resource pool, on the other hand, receiving side signal subscriber equipment can select physical resource to carry out input according to repetition transmission of configuration information from described transmission resource pool or reception resource pool.

Step 202: described subscriber equipment carries out input according to described repetition transmission of configuration information.
In step 201, subscriber equipment detects the repetition transmission of configuration information of the transmission of subscriber equipment in synchronizing channel sending signal, and now subscriber equipment also obtain the repetition transmission of configuration information of target UE simultaneously.
Here target UE can be: the subscriber equipment of the transmission signal detected; Or adopt the subscriber equipment of identical repetition transmission of configuration information with the subscriber equipment of the transmission signal detected; Or the subscriber equipment of the subscriber equipment same cells with the transmission signal detected; Or the subscriber equipment identical with the initial synchronisation source of the subscriber equipment of the transmission signal detected.
Concrete, when subscriber equipment obtains and repeats transmission of configuration information from synchronizing channel, also can obtain the transmission resource pool in synchronizing channel or receive resource pool information.
