Description
Technical field
The present invention relates to communication technical field, in particular to a kind of resource allocation method for D2D communication, one
Plant device for allocating resources, a kind of base station and a kind of terminal communicating for D2D.
Background technology
D2D (Device-to-Device, equipment is to equipment) communication is straight between the terminal that 3GPP Release-12 introduces
Connect the technology of letter, on the basis of traditional uplink and downlink communication link (i.e. uplink/downlink), introduce secondary link
(sidelink) concept.D2D communication technology has been completed the standardization of 3GPP Rel-12 and Rel-13, and current 3GPP is just
In the standardization carrying out Rel-14.D2D communication technology in Release 12 and Rel-13 mainly for public safety scene, from
Rel-14 begins for business scenario and is standardized.Additionally, the D2D technology of Rel-12 to Rel-14 is mainly for mandate frequency
Section, the related base station control signaling of D2D communication, synchronizing signal (the Sidelink Synchronization of terminal room
Signaling, abbreviation SLSS), the transmission of dispatching distribution signaling (Scheduling Assignment, abbreviation SA) and D2D data
All without the concern for the interference from unauthorized frequency range.
Based on the D2D communication technology authorizing frequency range, although the ability of direction communication between terminal can be provided, it is not take up grand
The downstream transmission resource of base station.But, if D2D communication technology be confined to authorize frequency range, exist larger industrialization and
Business deployment barrier.Under business deployment scenario, if D2D communication adopts same frequency with the cellular network of operator deployment
Section, then the interference that operator can may bring D2D communication is considered as a potential threat.On the other hand, D2D communication can bypass
The flow of a part of operator, leads to the business revenue of operator to reduce, for the heavier operator regarding flow operation, D2D
Communication technology deployment on authorizing frequency range lacks ripe business prototype.Therefore, D2D communication technology is opened up in unlicensed spectrum
Exhibition, becomes a choice of technology overcoming D2D communication technology commercial applications.
Existing D2D communication technology is not supported to carry out D2D transmission in unauthorized frequency range, when D2D terminal completes to find each other
Afterwards, the resource authorizing frequency range is transmitted, does not support to carry out D2D transmission in unauthorized frequency range.Therefore, prior art is no
Method utilizes the new LTE transmission technology (i.e. in new unauthorized frequency range) of 5G to carry out D2D data transfer.
Therefore, how to guarantee that D2D communication technology is applied to as technology urgently to be resolved hurrily in unlicensed spectrum
Problem.

Fig. 6 shows the schematic block diagram of terminal according to first embodiment of the invention.
As shown in fig. 6, terminal 600 according to first embodiment of the invention, including：It is used for D2D as shown in Figure 5
The device for allocating resources 500 of communication.
Below elaborate to carry out the scheme of resource distribution D2D communicates from base station side and end side respectively, below in conjunction with
Fig. 7 and Fig. 8 is illustrated on the whole further：
The communication resource of D2D transmission as shown in fig. 7, base station is passed through to coordinate, can be carried out to terminal 702 configuration, wherein extremely
Contain the communication resource that D2D transmission is carried out on unauthorized frequency range less and carry out D2D naturally it is also possible to be included in mandate frequency range
The communication resource of transmission, and then terminal 702 led to terminal 704 by the communication resource carrying out D2D transmission that base station configures
Letter.
Specifically, as shown in figure 8, mainly including the following steps that：
Step 802, coordinates between base station to determine the resource or resource pool carrying out D2D transmission.
Specifically, support that multiple frequency ranges that the base station of unauthorized frequency range is supported according to itself (potentially include mandate frequency range
With unauthorized frequency range), and the frequency range that the other base stations (can be multiple) that can be controlled by this base station are supported (potentially includes
Authorize frequency range and unauthorized frequency range) on carrier resource be analyzed, configuration carries out the resource of D2D transmission or resource pool (at least
Contain the communication resource in unauthorized frequency range it is also possible to comprise to authorize the communication resource in frequency range).
Wherein it is possible to other base stations are obtained by the interface signaling (by way of similar to X2 interface) between base station prop up
Carrier resource information in the frequency range held.
Base station carries out the resource of D2D transmission or the criterion of resource pool and side according to the resource distribution of acquired multiple carrier waves
Method potentially includes：Authorize the occupancy situation of frequency range Radio Resource, each on the percentage ratio such as having used, and unauthorized frequency range
The occupation condition of individual carrier wave.
Base station can directly obtain according to resource scheduling information to the judgement of the occupancy situation authorizing the resource of frequency range, and to non-
The occupancy situation authorizing the resource of frequency range then needs by indirectly mode, because there may be in unauthorized frequency range not controlled by base station
Other communication equipments of system.This indirectly mode potentially includes：The unauthorized resource of frequency range of terminal-pair being serviced according to base station
Intercept and report and be determined, or determined according to the data transmission state in unauthorized frequency range, such as postpone, packet loss
Deng.
Step 804, supports that system information or UE (User Equipment, Yong Hushe are passed through in the base station of unauthorized frequency range
Standby) related dedicated signaling carries out resource or the resource pool of D2D communication to terminal configuration.
Wherein, base station configuration carry out the resource of D2D communication or resource pool can be positioned partially or entirely in unauthorized frequency
Duan Shang.And the system information of base station or dedicated signaling can be enterprising in the carrier cell authorizing frequency range or unauthorized frequency range
Row sends.
If base station carries out the resource of D2D communication on authorizing frequency range by system information broadcast or dedicated signaling configuration
Or resource pool, then base station be required to cross-carrier support configuration to the D2D communication resource or resource pool in unauthorized frequency range,
This be due to base station configuration carry out contain the D2D communication money in unauthorized frequency range in the resource of D2D communication or resource pool
Source.
If base station passes through system information broadcast in unauthorized frequency range or dedicated signaling configuration carries out the money of D2D communication
Source or resource pool, and be that the resource to this cell configures, then need not to carry out cross-carrier operation unauthorized to configure for base station
The D2D communication resource in frequency range or resource pool.
Step 806, between terminal by base station configure carry out the resource of D2D communication or resource pool carries out D2D communication.
Wherein, if the D2D communication resource is entirely located in unauthorized frequency range, terminal, when carrying out data is activation, be sent out
The whole D2D data sent is required for sending by unauthorized frequency range.
If D2D communication resource part is located in unauthorized frequency range, and terminal by unauthorized frequency range and authorizes frequency range common
Send data, then need between terminal to realize the transmission of D2D data by the data cutting of multiple carrier waves and polymerization.
