Description

Communication resource management method, equipment and system

Technical field

The present invention relates to the communication technology more particularly to a kind of communication resource management methods, equipment and system.

Background technique

With the development of wireless multimedia service, the demand to high data rate and user experience is growing, thus right The power system capacity of conventional cellular network and covering propose high requirement, another aspect social networks, short distance data sharing, sheet The prevalence of the applications such as ground advertisement make interested persons or things near the right solution of people and communicate and adjacent service (PS, Proximity Services) demand gradually increase, it is traditional based on the cellular network of cell to high data rate and neighbour There are limitations in terms of nearly service support, and under this requirement background, the equipment for representing future communication technologies development new direction is arrived Equipment (D2D, Device-to-Device) technology is come into being, the application of D2D technology, can mitigate cellular network burden, It reduces the battery power consumption of user terminal (UE, User Equipment), improve data rate, and improve the Shandong of network infrastructure Stick meets the requirement of high data rate traffic and adjacent service.

D2D technology can work in authorized spectrum band or unauthorized frequency range, allow multiple user equipmenies for supporting D2D function, I.e. D2D user equipment (D2D UE, D2D User Equipment) is having network infrastructure or without the feelings of network infrastructure / direct communication is directly found under condition, Fig. 1 is the application scenarios schematic diagram of D2D in the related technology, as shown in Figure 1, mainly having Three kinds of scenes:

1) UE1 and UE2 carries out data interaction under the covering of cellular network, and user face data is set without network foundation It applies.

2) in weak/UE relay transmission without overlay area, the UE4 for allowing signal quality poor is by nearby there is the network coverage UE3 communicated with network, operator can be helped to spread over, improve capacity.

3) in the case where earthquake or emergency cellular network cisco unity malfunction occurs, allow equipment room directly logical Letter, UE5, control plane and user face all carry out a jump without network infrastructure between UE6 and UE7 or the data of multi-hop are logical Letter.

D2D technology generally includes D2D discovery technique and the D2D communication technology, and D2D discovery technique is for judging/determining two Or it is mutually adjacent between multiple D2D user equipmenies, such as can carry out within D2D direct communications range, or for judging/determining First user equipment is adjacent to second user equipment；The D2D communication technology makes part or all of communication data between D2D user equipment It can not directly be communicated by network infrastructure.

D2D communicate reusable cellular communication resources, have cellular network cover scene under, the D2D communication resource usually by Base station is scheduled distribution, and resource multiplex efficiency can be improved in this way, at the same guarantee network side to the D2D control communicated and The effect of interference coordination between D2D communication and cellular communication.The mode of the base station dispatching distribution D2D communication resource usually has following three Kind:

1) centralized scheduling refers to the communication between UE completely by network controls.

2) half centralized scheduling refers to that network side and UE joint carry out the scheduling of D2D communication.

Under half centralized scheduling mode, network side can be the identical D2D communication money of multiple D2D communication distribution semi-static to UE Source pond, by D2D communicate in control UE, e.g., D2D communicate centering main UE or D2D group group head UE be based on the D2D communication provides The reallocation of the source pond progress D2D communication resource.

3) distributed scheduling, i.e. D2D communication UE independently carry out the scheduling of D2D data transmission.

Wherein half centralized scheduling mode is the compromise proposal of centralized scheduling and distributed scheduling mode, it can be achieved that certain The network side of degree is to the D2D control communicated and guarantees resource multiplex efficiency, while control base station complexity and control letter of eating dishes without rice or wine Enable expense in zone of reasonableness.

For the same UE, if its support D2D function, may carry out simultaneously the D2D between another D2D UE communicate and Cellular communication between base station.The D2D communication resource is multiplexed cellular communication resources and using in the case of half centralized scheduling, and base station is The resource of D2D UE distribution may also be scheduled for the transmission of cellular communication data, be used since D2D is communicated with cellular communication The communication resource be not to be scheduled by the same base station, it is likely that the cellular communication of same UE and D2D are communicated identical Subframe carries out, and leads to self-interference problem in band spurious or equipment.

For example, under D2D communication multiplexing cellular uplink resource scene, if UE sends cellular uplink data in same subframe and connects D2D communication data is received, then the reception of severe jamming D2D data is reduced resource utilization by the transmission of cellular data；In addition, D2D UE cannot carry out the transmitting-receiving of D2D communication and cellular communication, if D2D UE in the case where only one sending and receiving end simultaneously Cellular communication communicate with D2D and be scheduled simultaneously, then D2D communication or cellular communication cannot be gone on smoothly.

In conclusion how to coordinate the scheduling of resource that cellular communication is communicated with D2D in half centralized scheduling scene, it is related Technology there is no solution.
