Description

Communication resource management method, equipment and system

Technical field

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

Background technology

Along with the development of wireless multimedia service, growing to the demand of high data rate and Consumer's Experience, thus high requirement is proposed to the power system capacity of conventional cellular network and covering, social networks on the other hand, closely data sharing, the popular of the application such as local advertising makes interested persons or things near the right solution of people and communicates with it and adjacent service (PS, Proximity Services) demand increase gradually, limitation is there is in traditional cellular network based on community to high data rate and adjacent service support aspect, under this requirement background, represent the device-to-device (D2D of future communication technologies development new direction, Device-to-Device) technology is arisen at the historic moment, the application of D2D technology, the burden of cellular network can be alleviated, reduce user terminal (UE, User Equipment) battery power consumption, improve data rate, and improve the robustness of network infrastructure, meet the requirement of high data rate traffic and adjacent service.

D2D technology can be operated in authorizes frequency range or unauthorized frequency range, allow the subscriber equipment of multiple support D2D function, i.e. D2D subscriber equipment (D2D UE, D2D User Equipment) when having network infrastructure or directly find/direct communication without when network infrastructure, Fig. 1 is the application scenarios schematic diagram of D2D in correlation technique, as shown in Figure 1, three kinds of scenes are mainly contained:

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

2) weak/without the UE relay transmission of overlay area, allow the poor UE4 of signal quality pass through near have the UE3 of the network coverage to communicate with network, operator can be helped to expand covering, raising capacity.

3), in generation earthquake or emergency, when cellular network cisco unity malfunction, allow equipment room direct communication, between UE5, UE6 and UE7, the data communication of a jumping or multi-hop is all carried out in chain of command and user face without network infrastructure.

D2D technology generally includes D2D discovery technique and the D2D communication technology, D2D discovery technique is for judging/determining between two or more D2D subscriber equipment vicinity mutually, such as can carry out within D2D direct communications range, or for judging/determining first user proximity of devices second subscriber equipment; The D2D communication technology, makes part or all of communication data between D2D subscriber equipment by network infrastructure, namely directly can not communicate.

D2D communication reusable cellular communication resources, under the scene covered there being cellular network, the D2D communication resource carries out dispatching distribution by base station usually, resource multiplex efficiency can be improved like this, ensure that the control that network side communicate to D2D and D2D communicate and the effect of interference coordination between cellular communication simultaneously.The mode that base station scheduling distributes the D2D communication resource has following three kinds usually:

1) centralized scheduling, refers to that communication between UE is completely by network controls.

2) half centralized scheduling, refers to that network side and UE combine the scheduling carried out D2D and communicate.

Under half centralized scheduling mode, network side can be multiple D2D communication D2D communication resource pond identical to the semi-static distribution of UE, the control UE in being communicated by D2D, as, the main UE of D2D communication centering, or the group head UE of D2D group carries out the reallocation of the D2D communication resource based on this D2D communication resource pond.

3) distributed scheduling, namely D2D communication UE independently carries out the scheduling of D2D transfer of data.

Wherein half centralized scheduling mode is the compromise proposal of centralized scheduling and distributed scheduling mode, management and control that network side to a certain degree communicates to D2D can be realized and ensure resource multiplex efficiency, controlling base station complexity and control signal expense of eating dishes without rice or wine at zone of reasonableness simultaneously.

For same UE, if it supports D2D function, then may carry out communicating with the D2D between another D2D UE simultaneously and and base station between cellular communication.The multiplexing cellular communication resources of the D2D communication resource and adopting in half centralized scheduling situation, base station is that the resource that D2D UE distributes also may be scheduled for cellular communication transfer of data, the communication resource used due to D2D communication and cellular communication is not dispatched by same base station, then likely cellular communication and the D2D of same UE communicate and to carry out in identical subframe, cause self-interference problem in spuious in band or equipment.

Such as, D2D communicates under multiplexing cellular uplink resource scene, if UE sends cellular uplink data in same subframe and receives D2D communication data, then the transmission of cellular data is by the reception of severe jamming D2D data, reduces resource utilization; In addition, D2D UE, when only having a sending and receiving end, can not carry out the transmitting-receiving of D2D communication and cellular communication simultaneously, be scheduled if the cellular communication of D2D UE communicates with D2D simultaneously, then this D2D communication or cellular communication can not be carried out smoothly.

In sum, in half centralized scheduling scene, how to coordinate the scheduling of resource that cellular communication communicates with D2D, correlation technique there is no solution.
