Step 800:UE2 reads the broadcast that around D2D network user device UE1 sends, wherein Comprise wave beam identification auxiliary information.

In the present embodiment, UE2 Yu UE1 supports D2D function, and UE2 is by obtaining what UE1 sent Wave beam identification auxiliary information, knows and there is high frequency base station about；Owing to D2D network is that short distance covers Network, therefore, what UE1 sent is its neighbouring high frequency site information, and can receive UE1 broadcast D2D equipment also should be near the HBS of high frequency base station.The particular content of wave beam identification auxiliary information is such as Shown in table 3:

Table 3

Fig. 9 is the signal of running time-frequency resource shared by each wave beam identification signal that third embodiment of the invention is corresponding Scheme, running time-frequency resource signal shared by HBS each wave beam identification signal as shown in Figure 9, in the 3rd embodiment, Owing to using the mode of code division to distinguish different beams, therefore, the sequence resources that each wave beam is used is the most just Handing over, each wave beam all can take identical running time-frequency resource, i.e. each wave beam in each wave beam recognition cycle Sequence all on the symbol 2,3,4 of each subframe the first time slot launch.Wherein, the beam transmission cycle Refer to that HBS completes the cycle that once all wave beam sends, i.e. UE can be complete in a wave beam recognition cycle Becoming the identification once to whole wave beams, the beam transmission cycle is 1 subframe (being assumed to be 1ms) here； Next cycle was the repetition in a upper cycle.
