Specific embodiment
Common cellular radio Communication system can be based on CDMA (CDMA, Code Division
Multiplexing Access) technology, frequency division multiple access (FDMA, Frequency Division Multiplexing
Access) technology, orthogonal frequency division multiple access (OFDMA, Orthogonal-FDMA) technology, single-carrier frequency division multiple access (SC-FDMA,
Single Carrier-FDMA) technology etc., for example, 3GPP (3rd Generation Partnership Project) is long-term
Under evolution (LTE, Long Term Evolution)/senior long term evolution (LTE-A, LTE-Advanced) cellular communication system
Line link (or being forward link) is based on OFDMA technology, and uplink (or being reverse link) is based on SC-FDMA technology.
In the system based on OFDMA/SC-FDMA technology, the radio resource (Radio Resource) for communication is
When-frequency bidimensional form.For example, the communication resource of uplink and downlink link is in time orientation for LTE/LTE-A system
On be all with radio frames (radio frame) for unit division, include 10 as shown in Figure 1, each wireless frame length is 10ms
Length is the subframe (sub-frame) of 1ms, and each subframe includes two time slots (slot) that length is 0.5ms.Before circulation
The configuration for sewing (CP, Cyclic Prefix) is different, and each time slot may include 6 or 7 OFDM or SC-FDM symbols.
In frequency direction, resource is unit division with subcarrier (subcarrier).In specific communication, frequency domain resource point
The minimum unit matched is resource block (RB, Resource Block), a Physical Resource Block of corresponding physical resource (PRB,
Physical RB), as shown in Fig. 2, a PRB includes 12 subcarriers (sub-carrier) in frequency domain, corresponding to time domain
One time slot.The resource of a corresponding subcarrier is known as resource unit (RE, Resource on each OFDM/SC-FDM symbol
Element, or be resource element).
In LTE/LTE-A cellular communication, UE passes through detection synchronization signal (SS, Synchronization Signal) hair
Existing LTE/LTE-A network, and obtain the downstream frequency and time synchronization with access node.Also, since synchronization signal carries
Physical Cell Identifier (PCID, Physical Cell ID), detection synchronization signal also imply that UE has found LTE/LTE-A cell.
For uplink, when UE has transmitting uplink data, need to initiate random access (RA, Random Access)
Uplink synchronous is carried out, and establishes wireless heterogeneous networks (RRC, Radio Resource Control) even to network side initiation
It connects, namely enters RRC connection (Connected) state from idle (Idle) state of RRC.In random access, UE needs to send
Random access preamble (preamble), network side are realized by detecting random access preamble in specific running time-frequency resource to UE

Fig. 3 show the network deployment schematic diagram of cellular radio Communication system, cellular radio Communication system shown in Fig. 3
It can be 3GPP LTE/LTE-A system, or the system based on other cellular radio Communication technologies.It is logical in cellular radio
In the access net of letter system, the network equipment generally comprise a certain number of base stations (base station, or referred to as node B,
Node B or node B, evolved Node B, the eNB of evolution, or node B, enhanced the Node B of enhancing,
), and other network entity (network entity) eNB.In a 3 gpp system, the logical of evolution can also be referred to as
With terrestrial access network (E-UTRAN, Evolved Universal Terrestrial Radio Access
Network).Here, the base station also includes the low power nodes (LPN, Low Power Node) accessed in network, such as milli
Picocell or Home eNodeB, for example be pico or Relay or femto or HeNB (Home eNB) etc..To describe simply simultaneously
Ambiguity is avoided, above-mentioned base station and low power nodes are referred to as access node herein.

UE in range can be carried out wireless communication with affiliated access node, and the wireless signal overlay area of an access node can be with base
It is divided into one or more cell (cell) or sector (sector) in the criterion of setting, such as can be three cells,
The wireless communication of each cell can have independent subsystem to be handled, such as independent radio frequency unit；For low-power section
The covered cell of point can also be by low-power section since area coverage is much smaller than the cell that traditional access node is covered
The covered cell of point is known as cell (small cell).

Line resource, device discovery procedure need the auxiliary of network side, are managed by the auxiliary of network side to equipment discovery, avoid setting
Preparation is existing to generate interference to cellular communication, and can be improved the efficiency of equipment discovery by the auxiliary of network side.Such as it can be with
The UE of radio resource by base station distribution for equipment discovery, D2D communication carries out equipment discovery in the radio resource distributed.
But, in LTE/LTE-A system, the radio resource of subordinate's cell of different access nodes may be it is nonsynchronous, it is this not
The equipment discovery radio resource for synchronizing the subordinate's cell that may result in different access nodes is different, in this way when UE belong to it is above-mentioned not
With access node subordinate's cell when, even if UE close proximity, may also cannot achieve equipment discovery, UE1 as shown in Figure 4 and
UE2.In other words, the method for discovering equipment of above-mentioned network assistance can only be realized in cell or the same access node subordinate
The user equipment of cell carries out equipment discovery, i.e. equipment finds the coverage area that will be limited by access node or cell.
Develop according to current cellular network, cell (small cell) may become LTE/LTE-A network Development
A universal direction.Under small cell scenario, the coverage area of cell will be very small (several hundred meters even tens meters)；Cause
This can undoubtedly make D2D if the range or distance of the discovery of D2D equipment are limited by the coverage area of access node or cell
The application of communication is very limited.
Based on above-mentioned consideration, the present invention provides a kind of method for discovering equipment, basic thought includes: that access node reception is set
