In existing LTE V2X technology, V2X terminal carries out resource selection on single carrier for business packet and goes forward side by side industry business Transmission does not support to be that multiple associated business packets carry out carrier wave selection under multi-carrier case.Meanwhile in the multiple carrier case, If supporting carrier wave selection, the behavior for carrying out carrier wave selection may influence the behavior of resource selection on determining carrier wave, for this purpose, The embodiment of the present application proposes a kind of resource selection method and device, to realize under multi-carrier case being multiple associated business packets Carry out resource selection.

Wherein, the multiple associated business packet can be multiple fragments an of business packet, be also possible to have association Multiple business packets of relationship.

The embodiment of the present application is described in detail with reference to the accompanying drawing.

It referring to fig. 2, is resource selection flow diagram provided by the embodiments of the present application, as shown, the process may include Following steps:

S201: terminal selects one or more candidate carriers from candidate carrier set, obtains transmission carrier set；Its In, the candidate transport carrier set is according to the load of candidate carrier, the candidate load in service attribute, candidate carrier set Resource occupation in wave set in candidate carrier excludes the selection of at least one of result.Wherein, the resource occupation excludes As a result it can be indicated with remaining candidate resource ratio.The resource occupation excludes result can be according to certain in multiple associated services packets The frequency domain resource size that a or each business packet transmission needs to occupy determines, can also transmit not based on associated services packet and need to account for Frequency domain resource size determines.The terminal can be the V2X terminal in framework shown in Fig. 1.

Wherein, the candidate carrier set can be preset.By taking the terminal is V2X terminal as an example, when it is implemented, can All or part of carrier wave on the working frequency range that V2X terminal is supported is as the candidate carrier in candidate carrier set.It needs The quantity for the candidate carrier selected from candidate carrier set can be pre-configured with or be configured by high level, and the embodiment of the present application is to this With no restriction.

In candidate carrier set, each candidate carrier is corresponding with respective resource.The corresponding resource of one candidate carrier, On frequency domain be the carrier wave frequency, in the time domain can with Transmission Time Interval (transmission time interval, TTI) or subframe is unit, naturally it is also possible to which as unit of the time quantum of other length, the embodiment of the present application does not limit this System.In the embodiment of the present application, optionally, a resource includes but is not limited to: being in the time domain TTI or subframe or one A short TTI, is below described the embodiment of the present application by taking subframe as an example.For example, for candidate carrier 1 and candidate carrier 2 Say, include: in the corresponding resource of candidate carrier 1 frequency domain be candidate carrier 1, in time domain be subframe 0, subframe 1 resource, candidate carries Include: in the corresponding resource of wave 2 frequency domain be candidate carrier 2, in time domain be subframe 1 and subframe 2 resource.

S202: terminal needs to occupy for each business packet in multiple associated business packets according to the transmission of corresponding service packet Frequency domain resource size, from it is described transmission carrier set all carrier resources exclude after surplus resources in, be corresponding service Packet selection resource.

In S201, terminal can be according to the load of candidate carrier, candidate carrier set in service attribute, candidate carrier set Resource occupation in middle candidate carrier excludes at least one of result, selects from candidate carrier set one or more candidate Carrier wave, selected candidate carrier out form transmission carrier set.Give to following exemplary several selection candidate carriers Method:

Candidate carrier selection method 1: candidate carrier is selected according to service attribute.

Service attribute may include type of service.Corresponding relationship between configurable type of service and candidate carrier, for example match Mapping table is set, may include type of service mark and candidate carrier mark (or number) in the mapping table.The correspondence Relationship can be pre-configured with (for example making an appointment) or be configured by high level.One type of service can correspond to one or more candidates Carrier wave, a candidate carrier can also correspond to one or more types of service.Terminal can according to the type of service of data to be transmitted, One or more candidate carriers corresponding with the type of service of the data to be transmitted are selected from candidate carrier set.

Service attribute may also comprise service priority.Corresponding relationship between configurable service priority and candidate carrier, Such as configuration mapping table, it may include that service priority mark and candidate carrier mark (or are compiled in the mapping table Number).The corresponding relationship can be pre-configured with (for example making an appointment) or be configured by high level.One service priority can correspond to one A or multiple candidate carriers, a candidate carrier can also correspond to one or more service priority.Terminal can be according to be transmitted The service priority of data selects one or more corresponding with the service priority of the data to be transmitted from candidate carrier set A candidate carrier.

Candidate carrier selection method 2: candidate carrier is selected according to carrier load.

Terminal can carry out carrier load measurement to each candidate carrier in candidate carrier set, and according to each candidate load The load of wave is ranked up candidate carrier, and the one or more of light load is then selected to wait from the candidate carrier after sequence Select carrier wave.It in practical applications, can be by carrying out channel busy rate (Channel Busy Ratio, CBR) or channel to carrier wave Occupancy (Channel Occupancy Ratio, CR) is measured to obtain the load of carrier wave.

Candidate carrier selection method 3: candidate carrier is selected according to service priority and carrier load.

Corresponding relationship between configurable service priority and candidate carrier, such as configuration mapping table, the correspondence are closed The value or value range of service priority mark that be in table may include and carrier load.The corresponding relationship can be pre-configured with It (for example making an appointment) or is configured by high level.One service priority can correspond to the value or value model of a carrier load It encloses, a candidate carrier can also correspond to the value or value range of one or more carrier loads.

Terminal can be according to the corresponding pass between the service priority and service priority and carrier load of data to be transmitted System determines carrier load corresponding with the service priority of data to be transmitted (for convenience of description, here by the industry of data to be transmitted Carrier load corresponding to business priority is known as first carrier load)；Then it can be waited according in the candidate carrier set measured The load for selecting carrier wave is ranked up the candidate carrier in candidate carrier set, the selection and the from the candidate carrier after sequence The corresponding one or more candidate carriers of one carrier load.

Candidate carrier selection method 4: need are transmitted according to the maximum business packet of frequency domain resource is occupied in multiple associated services packets The frequency domain resource size to be occupied determines the remaining candidate resource ratio of each candidate carrier in candidate carrier set, according to institute There is the respective remaining candidate resource ratio selection candidate carrier of candidate carrier.The following examples are needed with a business packet transmission The frequency domain resource size of occupancy is described for being indicated with sets of sub-channels, includes one or more in a sub-channels set Subchannel.

Firstly, all candidate carriers in carrier set are set to available, and all candidate provide candidate carrier is corresponding Source is set to available.

Then, each candidate carrier is carried out respectively occupying resource exclusion.Occupying resource exclusion may include following two side Face:

First aspect: for terminal in perception window send data all frequency domain resources in the time domain, determine the end Hold all possible reserve resource；If there are conflicted resource, (conflicted resource is that there are portions with reserve resource in candidate carrier set Point or all overlapping candidate resource), then by the conflicted resource from candidate carrier set the corresponding candidate resource of corresponding carriers Middle exclusion.

For example, the resource that terminal can be sent to data occupancy, which is known as skip subframe, (to be influenced by half-duplex, due to end Hold the unlisten subframe for being sent and being formed), terminal can be for skip subframe in perception (sensing) window, it is assumed that the son Other terminals are subscribed to resource next time with all periods of system configuration on frame, then if being directed to a candidate carrier, Subframe in corresponding candidate's subframes with the presence of candidate's subframes and above-mentioned reservation overlaps, or with the N after the candidate's subframes Subframe is sent used in secondary transmission in the presence of overlapping, then excludes the candidate's subframes from the corresponding candidate's subframes of the candidate carrier, Wherein, N=1,2 ..., 10*counter-1, counter are the maximum transmission times of system configuration.

Second aspect: the SA information sent according to other terminals listened in perception window determines other described ends Hold all possible reserve resource；If there are conflicted resource, (conflicted resource is that there are portions with reserve resource in candidate carrier set Point or all overlapping candidate resource) and the SA information indicated by PSSCH Reference Signal Received Power (reference Signal receiving power, RSRP) be higher than PSSCH-RSRP threshold value, then by conflicted resource from candidate carrier set It is excluded in the corresponding candidate resource of corresponding candidate carrier wave.

For example, terminal can monitor the SA information of other terminals transmission in sensing window, according to the SA listened to Information knows period and resource reservation information, and the son of other terminals reservation is determined according to the period and resource reservation information Frame.If being directed to a candidate carrier, there is the subframe of candidate's subframes and above-mentioned reservation in corresponding candidate's subframes and exist and hand over It is folded, or with transmission subframe used in the n-th transmission after the candidate's subframes in the presence of overlapping and signified according to the SA information The RSRP initial threshold that the RSRP of the PSSCH shown is higher than then excludes the candidate from the corresponding candidate's subframes of the candidate carrier Subframe.Wherein, the corresponding RSRP initial threshold possibility of different candidate carriers is identical may also be different, each to wait if identical Select the RSRP initial threshold of carrier wave consistent；If it is different, then it is corresponding that the candidate carrier is respectively adopted to each candidate carrier RSRP initial threshold carries out above-mentioned processing.

Finally, each candidate carrier after excluding for resource, occupies frequency domain resource most according in multiple associated services packets Big business packet transmission needs the quantity of the sets of sub-channels sub-channels occupied (below for convenience of description, by multiple association industry The maximum business packet of frequency domain resource, which is occupied, in business packet is known as the first business packet), determine residue of the candidate carrier after resource exclusion Meet the quantity of the candidate sub-channel set of the number of sub-channels requirement of first business packet occupancy in candidate resource, and determining should Candidate's that the number of sub-channels that candidate carrier meets first business packet occupancy in the candidate resource before resource exclusion requires The quantity of channel set；According to the candidate carrier determined resource exclusion before candidate sub-channel collective number and be Candidate sub-channel collective number after exclusion determines remaining candidate resource ratio (the remaining candidate resource ratio of the candidate carrier The candidate sub-channel collective number before candidate sub-channel collective number/resource exclusion after the exclusion of=resource), in this way, available The remaining candidate resource ratio of each candidate carrier in candidate carrier set.According to candidate load each in the candidate carrier set The remaining candidate resource ratio of wave selects one or more candidate carriers from the candidate carrier set.For example, can be according to every The sequence of the remaining candidate resource ratio of a candidate carrier from big to small, is ranked up candidate carrier, from the candidate after sequence The forward one or more candidate carriers of selected and sorted in carrier wave.Selected candidate carrier quantity, can be pre-configured with or appoint in advance It is fixed.

Candidate carrier selection method 5: it needs to occupy frequency domain resource according to business packet each in multiple associated services packets transmission Size determines the remaining candidate resource ratio of each candidate carrier in candidate carrier set, respective according to all candidate carriers Remaining candidate resource ratio selects candidate carrier.The following examples are big with the frequency domain resource that a business packet transmission needs to occupy It is small indicated with sets of sub-channels for be described, include one or more subchannels in a sub-channels set.

First aspect: for terminal in perception window send data all frequency domain resources in the time domain, determine the end Hold all possible reserve resource；If there are conflicted resource, (conflicted resource is that there are portions with reserve resource in candidate carrier set Point or all overlapping candidate resource), then by the conflicted resource from candidate carrier set the corresponding candidate resource of corresponding carriers Middle exclusion.Specific implementation process is similar with previous embodiment.

Second aspect: being directed to each candidate carrier, is believed according to the SA that other terminals listened in perception window are sent Breath determines all possible reserve resource of other described terminals；If in the candidate carrier there are conflicted resource (conflicted resource be with There is partly or entirely overlapping candidate resource in reserve resource) and the SA information indicated by the RSRP of PSSCH be higher than PSSCH-RSRP threshold value then excludes conflicted resource from the candidate resource in the candidate carrier.Wherein, the candidate resource It can be as unit of subchannel with the conflicted resource.Specific implementation process is similar with previous embodiment.

Second aspect: being directed to each candidate carrier, is believed according to the SA that other terminals listened in perception window are sent Breath determines all possible reserve resource of other described terminals；If in the candidate carrier there are conflicted resource (conflicted resource be with There is partly or entirely overlapping candidate PRB in reserve resource) and the SA information indicated by the RSRP of PSSCH be higher than PSSCH- RSRP threshold value then excludes conflicted resource from the candidate PRB in the candidate carrier.

Finally, the remaining candidate resource ratio of each candidate carrier is determined, according to the surplus resources of each candidate carrier ratio Example selects one or more candidate carriers from the candidate carrier set.For example, after executing above-mentioned resource exclusion processing, Remaining candidate resource ratio (the candidate PRB after remaining candidate resource ratio=resource exclusion can be calculated for each candidate carrier Candidate PRB quantity before quantity/resource exclusion), according to one or more more than the remaining candidate PRB of remaining candidate resource ratio selection A candidate carrier.

Above-mentioned candidate carrier selection method 1 is to candidate carrier selection method 7, only some examples, the embodiment of the present application institute The candidate carrier selection method of offer is not limited to that, according to the load of candidate carrier in service attribute, candidate carrier set, The method that any combination of resource in candidate carrier set in candidate carrier carries out candidate carrier selection, is all contained in the application Protection scope in.

It, can when terminal is used for the resource of data transmission based on the candidate carrier selection selected in the S202 of Fig. 2 process Using resource method for removing.The example provided by the embodiments of the present application that resource selection is carried out using resource method for removing is shown below Son.

Resource selection method 1:

(son that carrier set is candidate carrier set will be transmitted by transmission carrier set determined by S201 first Collection, wherein may include one or more carrier waves) in all candidate resources corresponding to each candidate carrier be set to available, then may be used Resource selection is carried out according to process shown in Fig. 3.

As shown in figure 3, the process can include:

S301: resource exclusion is carried out for each carrier wave in transmission carrier set.The resource exclusion may include following Two aspects:

First aspect: for terminal in perception window send data all frequency domain resources in the time domain, determine the end Hold all possible reserve resource；If transmitting in carrier set, there are conflicted resource, (conflicted resource is that there are portions with reserve resource Point or all overlapping candidate's subframes), then by conflicted resource from transmission carrier set in the corresponding candidate's subframes of corresponding carriers It excludes.

Second aspect: the SA information sent according to other terminals listened in perception window determines other described ends Hold all possible reserve resource；If transmitting in carrier set, there are conflicted resource, (conflicted resource is that there are portions with reserve resource Point or all overlapping candidate's subframes) and the SA information indicated by the RSRP of PSSCH be higher than PSSCH-RSRP threshold value, then The conflicted resource is excluded in the corresponding candidate's subframes of corresponding candidate carrier wave from transmission carrier set.

Resource exclusion side described in the specific implementation process and previous embodiment of resource method for removing provided by S301 Related content in method 1 or resource method for removing 2 is similar.

S302: for each carrier wave in transmission carrier set, the frequency domain resource for needing to occupy according to the transmission of each business packet Size determines the corresponding remaining candidate resource ratio of each business packet (if the frequency domain resource of business packet is combined into list using set of sub-channels Position, then the corresponding remaining candidate resource ratio=carrier wave of a business packet on a carrier wave meets the industry after resource exclusion Sets of sub-channels quantity/carrier wave that business packet frequency domain resource requires meets business packet frequency domain resource requirement before resource exclusion Sets of sub-channels quantity).If the corresponding remaining candidate resource ratio of each business packet is below given threshold for a carrier wave, It is then transferred to S303, is otherwise transferred to S304.

S303: if in S302, for the first carrier in transmission carrier set, the corresponding remaining candidate money of each business packet There is the corresponding remaining candidate resource ratio of part or all of business packet lower than given threshold in the ratio of source, is then mentioned according to setting thresholding It rises step-length to promote the corresponding PSSCH-RSRP threshold value of first carrier, and re-executes S301 for first carrier, with Resource exclusion is carried out to the first carrier again according to the PSSCH-RSRP threshold value after promotion.

Wherein, if in transmission carrier set, the corresponding PSSCH-RSRP threshold value of different carrier waves (such as initial p SSCH- RSRP threshold value) it is different, then thresholding is carried out on the basis of corresponding PSSCH-RSRP threshold value respectively to different carrier waves It is promoted.

S304: surplus on all carrier waves after being excluded to resource for each business packet in associated multiple business packets The candidate resource for meeting the frequency domain resource size that the transmission of corresponding service packet needs to occupy in remaining candidate resource, connects according to straight-through link Signal strength instruction (sidelink-received signal strength indication, S-RSSI) is received to be ranked up, One group of low candidate resource of S-RSSI, the one group candidate resource low from the S-RSSI are selected from the candidate resource after sequence In, resource is selected for corresponding service packet.It specifically, can be by all or part of candidate in the one group of S-RSSI low candidate resource Resource is as the resource for data transmission, can be from low one group of the S-RSSI for example, when selecting resource for business packet Resource is randomly choosed in candidate resource, and S-RSSI low candidate resource can also be selected from this group of candidate resource.

Since the resource of multiple business packets is selected from one group of low candidate resource of the S-RSSI, in order to keep away Exempt from resource contention, if a candidate resource in the one group of S-RSSI low candidate resource has been selected as the money of a business packet Source, the then candidate resource selected are no longer selected as the resource of other business packets, to guarantee that a resource can only be multiple A business packet in associated services packet uses, and cannot distribute to two or more business packets simultaneously and use.

Further, in order to reduce interference, if a candidate resource in the one group of S-RSSI low candidate resource is It is selected as the resource of a business packet, then other candidate resources in the time domain resource where selected resource are no longer It is selected as the resource of other business packets, to guarantee that the candidate resource in a time domain resource is assigned to only a business Packet uses.For example, the time domain resource where candidate resource is the son where the candidate PRB with candidate resource for candidate PRB For frame or short subframe, and the residue candidate PRB in the subframe or short subframe after resource exclusion includes PRB1 and PRB2, if the son PRB1 on frame or short subframe has been selected as the transfer resource of business packet 1, then, will not when selecting resource for other business packets Select the PRB2 in the subframe or short subframe.

Wherein, it is corresponding to account for all transmission carrier sets before the resource excludes for the one group of S-RSSI low candidate resource All candidate resources ratio be pre-configured or by high level configuration or it is identical as the given threshold.One candidate resource I-RSSI can be the linear mean values of RSSI of all subchannels on the candidate resource.

For example, by the obtained transmission carrier set of candidate carrier selection course include carrier wave 1 and carrier wave 2, It include: business packet 1, business packet 2 in multiple associated business packets.In S304, following resource selection process is executed:

For business packet 1, the frequency for needing to occupy is transmitted to business packet 1 is met in the remaining candidate resource of carrier wave 1 and carrier wave 2 The candidate resource of domain resource size, is ranked up according to S-RSSI, and one that S-RSSI is low is selected from the candidate resource after sequence Group candidate resource in one group of candidate resource low from the S-RSSI, selects resource for business packet 1；

For business packet 2, the frequency for needing to occupy is transmitted to business packet 2 is met in the remaining candidate resource of carrier wave 1 and carrier wave 2 The candidate resource of domain resource size, is ranked up according to S-RSSI, and one that S-RSSI is low is selected from the candidate resource after sequence Group candidate resource in one group of candidate resource low from the S-RSSI, selects resource for business packet 2.Wherein, if the S-RSSI is low One group of candidate resource in part candidate resource it is overlapping with the resource of distributing to business packet 1, then can be provided again for business packet Source selection, to guarantee that the resource of business packet 1 and business packet 2 does not clash.

Optionally, it can be successively based on according to the sequence of the frequency domain resource that business packet occupies from big to small for each business packet The remaining candidate resource for transmitting all carrier waves in carrier set carries out resource selection.It is of course also possible to be occupied according to business packet Frequency domain resource sequence from small to large or other settings sequences, be successively each business packet based in transmission carrier set The remaining candidate resource of all carrier waves carries out resource selection.

Above-mentioned resource selection process is applicable to the candidate carrier selection method of foregoing embodiments offer, is particularly suitable for Candidate carrier selection method 1, candidate carrier selection method 2 or candidate carrier selection method 3.

It should be noted that if using above-mentioned candidate carrier selection method 4, candidate carrier selection method 5, time in S201 Carrier selecting method 6 or candidate carrier selection method 7 is selected to carry out the selection of candidate carrier, then due to being directed to each candidate carrier Through having carried out resource exclusion, therefore in S202, can not have to be first carried out resource exclusion process (S301 can be omitted), but it is straight It connects and executes S302.If determining that the surplus resources ratio of candidate carrier is lower than given threshold according to S302, PSSCH- is being promoted After RSRP threshold value (S303), the resource exclusion process that S301 is executed according to the PSSCH-RSRP threshold value after promotion is still needed to.

Resource selection method 2:

(son that carrier set is candidate carrier set will be transmitted by transmission carrier set determined by S201 first Collection, wherein may include one or more carrier waves) in all candidate resources corresponding to each candidate carrier be set to available, then may be used Resource selection is carried out according to process shown in Fig. 4.

As shown in figure 4, the process can include:

S401: resource exclusion is carried out for each carrier wave in transmission carrier set.The resource exclusion may include following Two aspects:

S403: according to the step-length of setting that each carrier wave is corresponding for each carrier wave in transmission carrier set PSSCH-RSRP threshold value is promoted, according to the PSSCH-RSRP threshold value after promotion, for every in transmission carrier set A carrier wave re-executes S401.

S404: the linear mean value of S-RSSI of all available subchannels in each time domain resource is calculated, according to S-RSSI Linear mean value is ranked up available units time-domain resource, and one group that S-RSSI is low is selected from the time domain resource after sequence Time domain resource in one group of time domain resource low from the S-RSSI, selects the time domain for meeting the number of transmissions Resource；From be in each time domain resource for meeting the number of transmissions in the multiple associated business packet each business packet choosing Select resource.

It should be noted that if using above-mentioned candidate carrier selection method 4, candidate carrier selection method 5, time in S201 Carrier selecting method 6 or candidate carrier selection method 7 is selected to carry out the selection of candidate carrier, then due to being directed to each candidate carrier Through having carried out resource exclusion, therefore in S202, can not have to be first carried out resource exclusion process (S401 can be omitted), but it is straight It connects and executes S402.If determining that the surplus resources ratio of candidate carrier is lower than given threshold according to S402, PSSCH- is being promoted After RSRP threshold value (S403), the resource exclusion process that S401 is executed according to the PSSCH-RSRP threshold value after promotion is still needed to.
