Embodiment
Common cellular radio Communication system can be based on code division multiple access (CDMA, Code Division Multiplexing Access) technology, frequency division multiple access (FDMA, Frequency Division Multiplexing Access) technology, OFDM (OFDMA, Orthogonal-FDMA) technology, single-carrier frequency division multiple access (SC-FDMA, Single Carrier-FDMA) technology etc., for example, 3GPP (3rd Generation Partnership Project) Long Term Evolution (LTE, Long Term Evolution)/senior Long Term Evolution (LTE-A, LTE-Advanced) cellular communication system down link (or being called forward link) is based on OFDMA technology, up link (or being called reverse link) is based on SC-FDMA technology.
In the system based on OFDMA/SC-FDMA technology, be the form of time-frequency bidimensional for the Radio Resource (Radio Resource) of communicating by letter.For example, for LTE/LTE-A system, the communication resource of uplink and downlink link is all to divide taking radio frames (radio frame) as unit on time orientation, as shown in Figure 1, each radio frames length is 10ms, comprise the subframe that 10 length are 1ms (sub-frame), each subframe comprises that length is two time slots (slot) of 0.5ms.According to the configuration difference of Cyclic Prefix (CP, Cyclic Prefix), each time slot can comprise 6 or 7 OFDM or SC-FDM symbol.
In frequency direction, resource is divided taking subcarrier (subcarrier) as unit.In concrete communication, the least unit that frequency domain resource is distributed is Resource Block (RB, Resource Block), a Physical Resource Block (PRB of corresponding physical resource, Physical RB), as shown in Figure 2, a PRB comprises 12 subcarriers (sub-carrier) at frequency domain, corresponding to a time slot of time domain.On each OFDM/SC-FDM symbol, the resource of a corresponding subcarrier is called Resource Unit (RE, Resource Element, or be called resource element).
In LTE/LTE-A cellular communication, UE finds LTE/LTE-A network by detecting synchronizing signal (SS, Synchronization Signal), and the downstream frequency of acquisition and access node and time synchronized.And, because synchronizing signal carries Physical Cell Identifier (PCID, Physical Cell ID), detect synchronizing signal and also mean that UE finds LTE/LTE-A community.
For up link, in the time that UE has transmitting uplink data, need to initiate random access (RA, Random Access) carry out uplink synchronous, and initiate to set up Radio Resource control (RRC to network side, Radio Resource Control) connect, also enter RRC from RRC free time (Idle) state and connect (Connected) state.In the time of random access, UE need to send random access guiding (preamble), and network side is by detecting random access guiding in specific running time-frequency resource, realizes the synchronous of identification to UE and up link.
Figure 3 shows that the network design schematic diagram of cellular radio Communication system, the cellular radio Communication system shown in Fig. 3 can be 3GPP LTE/LTE-A system, or the system of cellular radio Communication technology based on other.In the Access Network of cellular radio Communication system, the network equipment generally comprises base station (the base station of some, or be called Node B, Node B, or the Node B of evolution, evolved Node B, eNB, or the Node B strengthening, enhanced Node B,, and other network entity (network entity) eNB).In 3GPP system, also can be referred to as the universal terrestrial access network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) of evolution.Here, described base station also comprises the low power nodes (LPN, Low Power Node) in access network, and for example Femto cell or Home eNodeB, such as being pico or Relay or femto or HeNB (Home eNB) etc.For describing simple and avoiding ambiguity, in this article above-mentioned base station and low power nodes are referred to as to access node.
In Fig. 3, only show 3 access nodes, each access node provides certain wireless signal coverage, UE in coverage can carry out radio communication with affiliated access node, the wireless signal overlay area of an access node can the criterion based on setting be divided into one or more community (cell) or sector (sector), for example can Shi Sange community, the radio communication of each community can have independently subsystem to process, for example radio frequency unit independently; The community covering for low power nodes, due to the community that area coverage covers much smaller than traditional access node, the community that therefore also low power nodes can be covered is called small-cell (small cell).
Carry out the device discovery of D2D communication in cellular communication system time, due to the Radio Resource of device discovery use cellular network, device discovery procedure needs the auxiliary of network side, by the auxiliary of network side, device discovery is managed, avoid device discovery that cellular communication is produced and disturbed, and by the auxiliary efficiency that can improve device discovery of network side.The Radio Resource that for example can be used for by base station assigns device discovery, the UE of D2D communication carries out device discovery in distributed Radio Resource.But, in LTE/LTE-A system, the Radio Resource of the subordinate community of different access nodes may be nonsynchronous, the device discovery Radio Resource difference of this asynchronous subordinate community that may cause different access nodes, like this in the time that UE belongs to the subordinate community of above-mentioned different access nodes, even if UE close proximity, may also cannot realize device 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 community or the subscriber equipment of same access node subordinate community carries out device discovery, and device discovery will be limited by the coverage of access node or community.
According to current cellular network development, small-cell (small cell) may become a general direction of LTE/LTE-A network Development.Under the scene of small-cell, the coverage of community will very little (some hundred meters even tens meters); Therefore,, if the scope of D2D device discovery or distance are limited by the coverage of access node or community, can make undoubtedly the application of D2D communication very limited.
Based on above-mentioned consideration, the invention provides a kind of method for discovering equipment, basic thought comprises: access node receiving equipment is found first resource configuration, configure for Secondary resource from resource to UE indicating equipment that find according to described device discovery first resource configuration integrate, and described Secondary resource configuration is sent to UE; The device discovery that described device discovery resource is carried out device-to-device communication for UE.
