Technical field
The present invention relates to field of communication technology, in particular to a kind of D2D resource allocation methods based on multicarrier,
A kind of D2D device for allocating resources, a kind of base station and a kind of terminal based on multicarrier.
Background technology
The prior art, that is, 3GPP Rel-12 only discuss D2D (Device-to-Device, equipment in single carrier wave
To equipment) the transmission mechanism that finds message, do not support D2D on multiple carrier waves to find the transmission mechanism of message.Therefore, it is based on mesh
Preceding technology can not realize that efficient D2D has found controlling mechanism under multicarrier environment.Meanwhile from 3GPP Rel-9
The mechanism of defined carrier wave polymerization, but how to be supported under carrier wave flowcollector aggregation scheme FlowCollector SCell (Secondary Cell, it is auxiliary
Cell) on D2D discovery mechanisms there is no disclosed scheme.Therefore, it is based on current technology, multiple carrier waves is cannot achieve and is supporting
Load balancing in terms of D2D discoveries, and the mechanism of carrier wave polymerization can not also be utilized to realize that the D2D across cell has found control machine
System.
Therefore, how the load balancing of D2D discovery procedures is realized under multicarrier environment, and realize across cell
D2D has found that control becomes technical problem urgently to be resolved hurrily.
Invention content
The present invention is based at least one above-mentioned technical problem, it is proposed that a kind of new D2D resources based on multicarrier
Allocation plan can realize the D2D discovery mechanisms across cell by the scheduling of main plot base station, ensure that over a number of carriers
The load balancing of D2D discovery mechanisms, and realize efficient D2D and find controlling mechanism, it avoids and goes out on a carrier wave
The problem that existing resource is excessively occupied and causes D2D discovery mechanisms less efficient.
In view of this, the present invention proposes a kind of D2D resource allocation methods based on multicarrier, suitable for being provided for terminal

The invention also provides a kind of terminal (not shown)s, including：D2D based on multicarrier as shown in Figure 4
Device for allocating resources 400.
Below in conjunction with Fig. 5 technical solutions that the present invention will be described in detail.
Technical scheme of the present invention is mainly：When UE (User Equipment, user equipment) is in connection status, and with
PCell (Primary Cell, main plot) establishes RRC (Radio Resource Control, radio resource control)
In the case of connection, if D2D has been carried out between PCell and SCell finds cooperateing with for resource information, and the rf chain of UE
Road (RF chain) can support to access two carrier waves where PCell and SCell simultaneously, then UE can not turned off and PCell
Between RRC connections, resource distribution is directly found according to the D2D of SCell obtained from PCell, is carried out on the carrier wave of SCell
D2D has found the transmission of message.Specific process flow is as shown in Figure 5：
As shown in figure 5, the D2D resource allocation methods based on multicarrier according to another embodiment of the invention, including：
Step 502, the coordinated exchange that D2D has found resource information is carried out between PCell and SCell.
Wherein, the concrete meaning of collaboration is that in PCell/ current carriers, whether the D2D with another carrier wave has found money to UE
Source controls and whether minizone has carried out the interaction that D2D has found resource information.
Step 504, UE RF capabilities report.
In order to enable PCell be able to determine whether can cross-carrier scheduling D2D find resource to UE, PCell needs are learnt
The radio-frequency receiving-transmitting ability of UE, specifically：
Whether UE gathers around there are two radio frequency link, to support the uplink and downlink on two carrier waves and D2D discovery business simultaneously；
If UE is injection frequency link, can UE support to carry out up and down in two cells in a manner of TDM (time division multiplexing)
Row transmitting-receiving and D2D have found business.
Meanwhile PCell also needs to know the configuration information of SCell, i.e. whether SCell is capable of providing D2D and finds resource, if
SCell can be provided, then PCell is determined to carry out UE the scheduling of the D2D discovery resources of multicarrier；If SCell is due to negative
The reason of load, can not provide D2D and find resource, then PCell determines that the D2D that multicarrier is not carried out to UE has found the scheduling of resource.
Step 506, PCell measures configuration to terminal.
Step 508, terminal is to PCell reporting measurement reports.
Step 510, PCell notifies the D2D of terminal selection SCell to find that resource adjusts the D2D transfer resources of terminal
Degree.
Specifically, it is being determined to find that resource is configured to the biography that D2D has found to terminal according to the D2D of some SCell
When defeated resource, can by PCell come control UE preferentially use the SCell carrier waves on scheduling method D2D find resource into
Row D2D has found, i.e., completes the scheduling that the D2D on SCell has found resource by PCell.Certainly, UE can also disconnect RRC with PCell
Connection, and establish RRC with SCell and connect, directly to carry out the scheduling that D2D has found resource by SCell.
The load balancing of the discoveries of the D2D on multiple carrier waves may be implemented in the technical solution of the above embodiment of the present invention, avoids
The problem of resource for some carrier wave occur excessively is occupied；Meanwhile technical scheme of the present invention may be implemented in CA
The high efficiency of cross-carrier resource is controlled under the frame of (Carrier Aggregation, carrier wave polymerization).
Technical scheme of the present invention is described in detail above in association with attached drawing, it is contemplated that be based on current technology, cannot achieve
Load balancing of multiple carrier waves in terms of supporting D2D discoveries, and also the mechanism of carrier wave polymerization can not be utilized to realize across cell
D2D has found controlling mechanism.Therefore, the present invention proposes a kind of new D2D resource allocation proposals based on multicarrier, can pass through
The D2D discovery mechanisms across cell are realized in the scheduling of main plot base station, ensure that the load of D2D discovery mechanisms over a number of carriers
Equilibrium, and realize efficient D2D and find controlling mechanism, avoid occur on a carrier wave resource excessively occupied and
The problem for causing D2D discovery mechanisms less efficient.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
