Description

A kind of resource allocation methods, control node and subscriber equipment

Technical field

The present invention relates to device-to-device (D2D, Device-to-Device) technology, espespecially a kind of resource allocation methods, control node and subscriber equipment.

Background technology

Development along with wireless multimedia service, on the one hand, people are also growing to the demand of high data rate and Consumer's Experience；On the other hand, public safety, social networks, the closely application scenarios such as data sharing, local advertising make that people are right to be desorbed nearly persons or things and communicate the demand of i.e. adjacent service (PS, ProximityServices) and be also gradually increased.So, higher requirement will be proposed for the power system capacity of conventional cellular network and covering.

But, traditional cellular network centered by base station, be there is obvious limitation in the support aspect of high data rate and adjacent service, under this requirement background, device-to-device (D2D, the Device-to-Device) technology representing future communication technologies development new direction is arisen at the historic moment.The application of D2D technology, it is possible to the burden alleviating cellular network, the battery power consumption reducing subscriber equipment, raising data rate, and improve the robustness of network infrastructure, meet the requirement of above-mentioned high data rate traffic and adjacent service well.

D2D technology can be operated in mandate frequency range or unauthorized frequency range, multiple subscriber equipment supporting D2D function and D2D subscriber equipment (D2DUE, D2DUserEquipment) is allowed to carry out when having network infrastructure or without network infrastructure directly find/directly communicating.At present, the application scenarios of D2D mainly has three kinds: Yi Zhongshi, UE1 and UE2 carry out data interaction under the covering of cellular network, and user face data is without network infrastructure, pattern 1 as shown in Figure 1；Another kind is, for weak/without the UE4 under the UE relay transmission of overlay area, pattern 2 as shown in Figure 1, it is allowed to the poor UE4 of signal quality pass through near have the UE3 of the network coverage and network to communicate, operator so can be helped to spread over, improve capacity；Also having one is earthquake or emergency are occurring, when cellular network cisco unity malfunction, equipment room is allowed directly to communicate, pattern 3, UE5 as shown in Figure 1, between UE6 and UE7, chain of command and user face all carry out the data communication of a jumping or multi-hop without network infrastructure.

D2D technology generally includes D2D discovery technique and D2D communication technology.Wherein, D2D discovery technique refers to, for determining whether first user equipment is close to the technology of the second subscriber equipment, generally, can find the other side by sending or receive discovery signal between D2DUE；D2D communication technology refers to, between D2D subscriber equipment, part or all of communication data can not be made directly the technology of communication by network infrastructure.

D2DUE is before carrying out D2D discovery or D2D communication, first, it is required for obtaining respective Radio Resource respectively, progress according to existing 3GPP standards meetings, no matter it is that D2D finds or the acquisition Radio Resource in D2D communication, all there is the two spike-type cultivars method of salary distribution, namely select the mode obtaining resource distribution to obtain resource (also referred to herein simply as the first resource method of salary distribution) based on UE or be that the proprietary resource (also referred to herein simply as the Secondary resource method of salary distribution) of UE dispatching distribution carries out D2D discovery or D2D communication by base station.Wherein, the first resource method of salary distribution is generally by base station or one D2D resource pool of system predistribution, participate in the UE that D2D finds or D2D communicates, or become adjacent service UE (ProSeUE, ProximityServicebasedUE) monitor this resource pool, and select the mode obtaining resource distribution to obtain Radio Resource by UE；And the Secondary resource method of salary distribution is the ProSeUE suitable Radio Resource of distribution by base station according to the request of ProSeUE.

In prior art, the uplink transmission power of Cellular Networks is distributed in base station in units of subframe for UE, the size of transmitting power depends on path loss, Resources allocation number and modulation coding mode etc., owing to being limited to maximum transmission power, when UE only sends cellular data in this subframe, the maximum transmission power of cellular services is the maximum transmission power of UE.But, for D2DUE, be likely to i.e. D2D business and the cellular services that send cellular data and D2D data at a subframe internal memory at the same time occur simultaneously, so, now the maximum transmission power of cellular services is no longer just the maximum transmission power of UE, because UE also needs to distribution portion transmitting power to D2D business, namely the maximum transmission power of cellular services is the transmitting power that the maximum transmission power of UE deducts D2D business.When D2DUE is obtained resource by the Secondary resource method of salary distribution and is carried out D2D communication, it is that UE distributes subframe position by base station, base station is by time resource position (T-RPT, Time-ResourcePatternforTransmission) index is handed down to UE, UE then determines the subframe position of distribution according to T-RPT index, and sends D2D signal in the subframe position determined.But, if UE obtains resource by the first resource method of salary distribution carries out D2D communication, then being determined to send the subframe position of D2D signal by UE, base station does not know that.

In one cell, the first resource method of salary distribution is used to obtain resource and carry out D2D communication and obtain resource by the Secondary resource method of salary distribution and to carry out the D2D UE communicated be simultaneous with using, so according to current technology scheme, some UE that base station is not probably known in community can send D2D signal in which subframe.For this situation, according to existing protocol, UE can pass through transmit power surplus (PHR, PowerHeaderRoom) tell the size of station spare transmitting power, for non-D2DUE, pertain only to cellular services and send, the change of PHR value is slowly, UE not may require that frequent transmission, only meets specific condition, and such as path loss just can send PHR value when varying more than given scope, timer expiry and secondary cell (Scell) activation etc..Base station can adjust the UE transmitting power size at next sub-frame of uplink according to the UE PHR value sent, thus distributing suitable resource number and modulation coding mode.nullBut，For D2DUE，Owing to it sends D2D data in specific subframe，Would be likely to occur i-th subframe and send D2D data and cellular data simultaneously，The possibility of cellular data is only sent in (i+1) individual subframe，In this case，If in i-th subframe and (i+1) individual subframe，D2DUE is identical at the uplink transmission power of Cellular Networks，So，Due to its Cellular Networks can maximum transmission power different，Its PHR value is different，Condition is sent according to existing PHR，Although comparing i-th subframe，UE is likely to greatly in the PHR change of (i+1) individual subframe，But still PHR will not be transmitted，So，Base station carries out ascending power adjustment distribution in (i+1) individual subframe still according to the PHR value sent in i-th subframe，Obviously the adjustment judgement of mistake is caused，Have impact on D2DUE performance.

On the other hand, owing to the transceiver of UE is fixing, thus having influence on carrier aggregation (CA) ability and multiple antennas (MIMO) ability of UE, if UE sends D2D data and cellular data in i-th subframe simultaneously, so, owing to the part transceiver of UE is used for sending D2D data, thus be accordingly used in the transceiver of communicating cellular data and may reduce thus having influenced whether that UE receives CA ability and the MIMO ability of cellular data, if the capacity variation of UE is not known in base station, obviously the resource allocation problem that can make the mistake, the performance of influential system.

In sum, D2D business and cellular services is supported according to existing demand D2DUE, D2D business and cellular services are likely to occur simultaneously, it is also possible to non-concurrent occur, it is limited for D2DUE, total transmitting power and emissivities (such as multiple antennas ability), but, the D2D business of D2DUE and the power of cellular services and resource distribution are not provided perfect solution by prior art, so it is difficult to ensure that the realization transmitted of D2D business and cellular services.
