Description

Resource configuration method used for device to device communication mode, apparatus and system
Resource allocation method, device and system technical field for equipment to equipment communication mode
The present invention relates to the communications field, more particularly to a kind of equipment that is used for is to equipment（D2D, Device to Device) resource allocation method of communication mode, device and system.Background technology
D2D communication modes refer to two user equipmenies（UE, User Equipment) between directly set up communication link and communicated, packet is not without by core net, pass through base station even.Fig. 1 show two user equipmenies for belonging to same base station（UE1 and UE2) set up the schematic diagram that D2D communicates.Fig. 2 show two user equipmenies for belonging to different base station（UE1 and UE2) set up the schematic diagram that D2D communicates.
It can be set up before D2D direct communications between UE, it may be necessary to carry out D2D discoveries（D2D Discovery) mutual discovery between process, i.e. UE1 and UE2.For example, signal is found in order to realize that UE2 has found that UE1, UE1 need to send on some running time-frequency resource（Discovery signal), UE2 will send on the running time-frequency resource for finding signal in UE1 and detect, to find UE1.The running time-frequency resource found shared by signal is sent for UE1, UE1 will choose from a resource pool, or directly be dispatched by base station.Resource pool for choosing running time-frequency resource for UE1, by base station configuration notification UE or can pre-set.Fig. 3 is the schematic diagram of resource pool, and subframe 2,4,7,9 belongs to the transmittable resource for finding signal, and UE therefrom selected part subframe can have found signal for sending.
For the terminal in different base station, as shown in Fig. 2 its resource pool is configured by respective base station respectively, or it is pre-configured with.After being found mutually by discovery mechanism, UE1 and UE2 can carry out D2D communications, and UE1 selected section resources from the resource pool for sending data are used to send data.UE2 blind detection resources pond is to receive the data that UE1 is sent.In such a scenario, because respective discovery resource is configured by different base station, how UE knows send signal in which resource, to ensure to letter signal can be received, and UE should do blind check in which resource, ensure that efficient reception, to signal is found, is the research emphasis of industry.
It should be noted that the introduction to technical background is intended merely to the convenient explanation clear, complete to technical scheme progress above, and facilitates the understanding of those skilled in the art and illustrate.Can not be merely because these schemes be set forth in the background section of the present invention and think that above-mentioned technical proposal is known to those skilled in the art.The content of the invention At present, industry proposes two methods to solve the problem of background technology is pointed out, first method is the same resource pool of all base station configurations, and each UE only needs to configure a resource pool, and the resource pool is both used to send to find signal, is also used for receiving signal.The advantage of this method is to find that resource shared by signal is selected from same resource pool, and the resource pool that receiving terminal UE blind checks are fixed improves accuracy rate, has been also convenient for the D2D discoveries across base station.However, the shortcoming of this method is that resource efficiency is not high, because different districts are different to the demand of resource pool, in this case, and the same resource pool of configuration, the resource utilization of the cell low to resource requirement is than relatively low.Second method is each base station autonomous configuration resource pool, and each local resource pond is notified adjacent base station.The advantage of this method is that each base station configures resource pool on demand, improves resource utilization.Disadvantage is however that, UE needs the blind check signal on all local resource ponds, so, UE is needed at one than blind check signal on larger resource pool, UE blind check efficiency is reduced, more energy are consumed, influence also result on normal cellular communication.
