Embodiment mono-,

Corresponding (1) kind mode.

As shown in Figure 8, the base station notice side of discoverying UE and the shared resource information of the side's of being found UE discovery signals, the side of being found UE sends discovery signals, the side of discovery UE according to the decoded result of discovery signals to base station feedback discovery signals reception quality information.

Concrete, at network side, comprising:

Step 1: when UE initiates the request of discovery other end UE to network, or eNB receives core network signalling, need to carry out discovery procedure to two UE, or based on the algorithm of eNB, need between two UE, initiate discovery procedure, eNB determines discovery side UE and the side of being found UE according to the instruction in request or algorithm, and notify discovery side UE and the side of being found UE with the form of dedicated signaling respectively, the information of the shared resource of its discovery signals, comprises time-frequency domain resources, code-point or out of Memory.

And network side also can be notified condition or the thresholding of its detection of discovery side UE.Extra, because the information such as transmitting time point and decode time of discovery signals is clearer and more definite, the time point eNB of feedback result also can roughly calculate out, therefore also can give discovery side UE by pre-configured feedback result ascending resource used;

Step 2: network side is in the pre-configured feedback that receives according to schedule discovery side UE on the running time-frequency resource of feedback result of giving, or there is no feedback on reservation resource, eNB uses the mode of PDCCH dynamic dispatching according to temporal reckoning, give discovery side UE at a suitable ascending resource of time point scheduling, in order to send feedback result, the moment that for example discovery signals sends is n, hypothesis decoding is k with organizing the duration of feedback packet, eNB can give discovery side UE scheduling an ascending resource in the n+k moment, in order to transmit feedback result;

Step 3: network side is resolved feedback result, and according in time triggering following flow process of feedback result, if for example feedback result is two set UE discovery procedures successes, and meets the condition of D2D communication, follow-uply may trigger D2D communication link process of establishing.

The side of being found UE side:

Step 0: alternatively, the side of being found UE can be initiatively to the discovery procedure of network side request and the opposing party side of discovery UE, or request is D2D process of establishing, because the prerequisite of setting up is to find, therefore first trigger discovery procedure, demand signalling can be to send to for example eNB of RAN contact, may be also to send to core net node;

Step 1: the side of being found UE receives network side dedicated signaling, knows the resource location for sending discovery signals, code-point and other information;

Step 2: when arriving the moment of predetermined transmission discovery signals, the side of being found UE sends discovery signals in a predetermined manner according to being configured in predetermined resource;

The transmission of above discovery signals may be also to send more than once, can repeatedly send according to the configuration of network side, if network side has configured repeatedly, UE acts in accordance with it.The discovery procedure of the side of being found UE side finishes.

The side of discovery UE side
