Description

Information uploading method, resource allocation methods, user equipment and base station

Technical field

The present invention relates to the communications field more particularly to information uploading method, resource allocation methods, user equipment (User Equipment, UE) and base station.

Background technique

In car networking (Vehicle to everything, V2X), the resource selection of mode (mode) 3UE is to be based on drilling Into type base station (Evolved Node B, eNB) scheduling, the resource selection of mode 4UE is monitoring (sensing) knot based on UE Fruit oneself selection, the resource pool of mode 3UE and mode 4UE are separated namely mode 3UE and mode 4UE will not be same Signal is sent in a resource pool.

In the car networking (Enhancement Vehicle to everything, eV2X) of evolution, due to needing to improve The utilization rate of resource, needs that research mode 3UE and mode 4UE share the same resource pool namely mode 3UE and mode 4UE exists Signal is sent in the same resource pool.Since mode 4UE is to carry out resource selection based on snoop results, mode 4UE can To monitor the occupation condition of mode 3UE and other modes 4UE, to avoid conflicting with other UE.But for mould Formula 3UE, base station does not know the resource selection situation of mode 4UE when carrying out resource allocation, therefore mode 3UE is needed to resource pool It is monitored, and snoop results reporting base station is scheduled so that base station is based on the snoop results.

In the prior art, UE reports whole snoop results, that is to say, that reports each subframe of the running time-frequency resource of monitoring In every sub-channels (subchannel) occupation condition.Mode 3UE needs to report snoop results, but if has reported Whole snoop results, the data volume reported is very big, since the UE time domain scale that can be monitored is up to 100ms (i.e. 100 sons Frame), frequency domain be maximum 25 sub-channels (i.e. 4 Physical Resource Block (physical resource block, PRB), 20MHz bandwidth), therefore maximum demand reports the occupancy situation of 2500 resource units.Also, since snoop results are dynamic changes , therefore every time before scheduling method 3UE, mode 3UE requires to report snoop results, to occupy more up channel money Source causes uplink channel resources to waste.

Summary of the invention

In one provided in an embodiment of the present invention typical application scenarios, in eV2X, mode 3UE and mode 4UE are shared The same resource pool, mode 3UE need to monitor the running time-frequency resource in resource pool, and by snoop results reporting base station so as to Base station is based on the snoop results and is scheduled.The embodiment of the present invention relates generally to how mode 3UE reports snoop results, Yi Jiji The scheduling of resource process stood.It is understood that the UE mentioned in following embodiment of the present invention can be any need to base station The UE for reporting snoop results can be, but not limited to as the mode 3UE in eV2X.In the embodiment of the present invention, when UE is needed to base station When reporting snoop results, UE only reports a part of snoop results, for example, only reporting the snoop results of one of dimension, base station It is that the UE carries out resource allocation according to above-mentioned a part of snoop results that UE is reported, thus avoiding the UE and other UE from conflicting On the basis of saved uplink channel resources.

Fig. 1 is a kind of communication scheme of resource allocation methods provided in an embodiment of the present invention, this method comprises:

Step 101, UE determines first resource subset or Secondary resource subset according to the snoop results of running time-frequency resource；Wherein, The first resource subset includes assignable time-domain resource and/or frequency domain resource in the running time-frequency resource, the Secondary resource Subset includes indistributable time-domain resource and/or frequency domain resource in the running time-frequency resource.

It is understood that the first resource subset and the Secondary resource subset are the son of the running time-frequency resource Collection.

A kind of optional scheme, UE is according to the snoop results of running time-frequency resource, when determining assignable in the running time-frequency resource Indistributable time-domain resource in domain resource or the running time-frequency resource, the unit of above-mentioned time-domain resource can be subframe.

In one example, the UE determines assignable sub- letter in the first subframe according to the snoop results of running time-frequency resource The ratio of the number for the subchannel for including in the number in road and first subframe, if the ratio is greater than or equal to the first threshold Then the first resource subset is added in first subframe by value, or, if the ratio is less than or equal to first threshold Then the Secondary resource subset is added in first subframe by value.According to the embodiment, if first threshold is larger, can divide Idle subchannel is more in the subframe matched, then when the subframe is reserved in base station, the resource reserved for the UE is more.

In another example, the UE determines assignable son in the second subframe according to the snoop results of running time-frequency resource The ratio of the number for the subchannel for including in the number of channel and second subframe, if the ratio is less than or equal to second Then the first resource subset is added in second subframe by threshold value, or, if the ratio is greater than or equal to second threshold Then the Secondary resource subset is added in second subframe by value.According to the embodiment, if second threshold is smaller, can divide Idle subchannel is less in the subframe matched, then when the subframe is reserved in base station, the resource reserved for the UE is less, can have more Resource allocation give other UE.

In another example, for the UE according to the snoop results of running time-frequency resource, determining will be described in M third subframe addition First resource subset, the M are greater than or equal to third threshold value；Or, snoop results of the UE according to running time-frequency resource, determine N The Secondary resource subset is added in a 4th subframe, and the N is less than or equal to the 4th threshold value.Exemplary, the 4th threshold value can Think the number of sub frames of the third threshold value or the running time-frequency resource and the difference of the third threshold value, or is predefined one Value.Can be very few to avoid the resource reserved for the UE by setting third threshold value or the 4th threshold value according to the embodiment, really Protect is that the UE reserves sufficient resource.It is understood that the embodiment is only to first resource subset or Secondary resource The restriction of the number of the subframe of concentration.The selection mode of above-mentioned third subframe can be taken mentioned by first threshold or the second threshold Value chooses the mode of the subframe that the first resource subset is added, and but not limited to this；The selection mode of above-mentioned 4th subframe It can take mentioned by first threshold or second threshold and choose the mode for the subframe that the Secondary resource subset is added, still It is without being limited thereto.

In a kind of possible embodiment, the first threshold, the second threshold, the third threshold value or described Four threshold values and sidelink received signal strength indicator (Sidelink Received Signal Strength Indicator, S-RSSI), the busy ratio of channel (Channel Busy Ratio, CBR), close on traffic packets priority (ProSe Per- Packet Priority, PPPP) in one or more it is related, which can pass through that network is (pre-) to be configured or standard Regulation.According to the embodiment, the first threshold, the second threshold, the third threshold value or the 4th threshold value can be with According to the occupation condition in Current resource pond carry out it is semi-static or dynamic adjustment or according to the UE business currently to be sent into Row is semi-static or dynamic adjusts, to meet actual demand.

In a kind of possible embodiment, the first threshold, the second threshold, the third threshold value or described Four threshold values have multiple preset values, and the UE selects one to preset according to the snoop results of running time-frequency resource from the multiple preset value Value is as the first threshold, the second threshold, the third threshold value or the 4th threshold value.According to the embodiment, institute Stating first threshold, the second threshold, the third threshold value or the 4th threshold value can be according to the snoop results of running time-frequency resource It carries out semi-static or dynamic to adjust, to meet actual demand.

It is to be appreciated that the first threshold, the second threshold, the third threshold value or the 4th threshold value can also It is set by by way of standard regulation or network (pre-) configuration.

Another optional scheme, for UE according to the snoop results of running time-frequency resource, frequency can be distributed by determining in the running time-frequency resource Inseparable in domain resource or the running time-frequency resource to match frequency domain resource, the unit of above-mentioned frequency domain resource can be subchannel.

In one example, the UE determines assignable son in the first subchannel according to the snoop results of running time-frequency resource The ratio of the number for the subframe for including in the number of frame and first subchannel, if the ratio is greater than or equal to the 5th threshold Then the first resource subset is added in first subchannel by value, or, if the ratio is less than or equal to the 5th threshold Then the Secondary resource subset is added in first subchannel by value.It, can if the 5th threshold value is larger according to the embodiment Idle subframe is more in the subchannel of distribution, then when the subchannel is reserved in base station, the resource reserved for the UE is more.

In another example, the UE is determined assignable in the second subchannel according to the snoop results of running time-frequency resource The ratio of the number for the subframe for including in the number of subframe and second subchannel, if the ratio is less than or equal to the 6th Then the first resource subset is added in second subchannel by threshold value, or, if the ratio is greater than or equal to the described 6th Then the Secondary resource subset is added in second subchannel by threshold value.According to the embodiment, if the 6th threshold value is smaller, Idle subframe is less in assignable subchannel, then when the subchannel is reserved in base station, the resource reserved for the UE is less, can be with There are more resource allocations to other UE.

In another example, the UE is determined M third subchannel institute is added according to the snoop results of running time-frequency resource First resource subset is stated, the M is greater than or equal to the 7th threshold value；Or, snoop results of the UE according to running time-frequency resource, determining will The Secondary resource subset is added in N number of 4th subchannel, and the N is less than or equal to the 8th threshold value.It is exemplary, the 8th threshold value It can be the difference of the number of subchannels and the 7th threshold value of the 7th threshold value or the running time-frequency resource, or be predefined One value.It can be to avoid the resource mistake reserved for the UE by the 7th threshold value of setting or the 8th threshold value according to the embodiment It is few, it is ensured that sufficient resource is reserved for the UE.It is understood that the embodiment is only to provide to first resource subset or second The restriction of the number of subchannel in the subset of source.The selection mode of above-mentioned third subchannel can be taken mentioned by the 5th threshold value Or the 6th threshold value choose the mode of the subchannel that the first resource subset is added, but not limited to this；Above-mentioned 4th son letter The selection mode in road can take mentioned by the 5th threshold value or the 6th threshold value the son chosen and the Secondary resource subset is added The mode of frame, but not limited to this.In a kind of possible embodiment, the 5th threshold value, the 6th threshold value, described Seven threshold values or the 8th threshold value are related to the one or more in S-RSSI, CBR, PPPP, which can pass through net (pre-) configuration of network or standard regulation.According to the embodiment, the 5th threshold value, the 6th threshold value, the 7th threshold value or 8th threshold value can carry out semi-static or dynamic adjustment according to the occupation condition in Current resource pond or be worked as according to UE Before the business to be sent carry out semi-static or dynamic and adjust, to meet actual demand.

In a kind of possible embodiment, the 5th threshold value, the 6th threshold value, the 7th threshold value or described Eight threshold values have multiple preset values, and the UE selects one to preset according to the snoop results of running time-frequency resource from the multiple preset value Value is as the 5th threshold value, the 6th threshold value, the 7th threshold value or the 8th threshold value.According to the embodiment, institute Stating the 5th threshold value, the 6th threshold value, the 7th threshold value or the 8th threshold value can be according to the snoop results of running time-frequency resource It carries out semi-static or dynamic to adjust, to meet actual demand.

It is to be appreciated that the 5th threshold value, the 6th threshold value, the 7th threshold value or the 8th threshold value can also It is set by by way of standard regulation or network (pre-) configuration.

Step 102, UE sends the first information to base station, and the first information is used to indicate the first resource subset or institute State Secondary resource subset.

It is understood that exemplary, the first resource subset and the Secondary resource subset are complementary relationships, two The intersection of person is the running time-frequency resource, therefore can determine the Secondary resource subset by the first resource subset, is passed through The Secondary resource subset can determine the first resource subset, that is to say, that no matter first information instruction first resource is sub Collection or instruction Secondary resource subset, can determine assignable time-domain resource in the running time-frequency resource by the first information And/or frequency domain resource.

In one example, UE can compare the number of resources that first resource subset includes and the money that Secondary resource subset includes Source number, i.e. UE can be used to indicate first resource subset or Secondary resource according to the busy ratio CBR selection first information of channel Subset.If the number of resources that first resource subset includes is greater than or equal to the number of resources that Secondary resource subset includes, i.e. channel is more empty In the spare time, assignable resource is more, then indicates Secondary resource subset by the first information；If the number of resources that first resource subset includes Less than or equal to the number of resources that Secondary resource subset includes, i.e. channel is relatively busy, and assignable resource is less, then passes through the first information First resource subset is indicated, to reduce the bit number of first information occupancy, effectively save uplink transmission resource.In the example In, base station needs to judge according to CBR that the first information is used to indicate first resource subset or is used to indicate Secondary resource subset； Or UE needs to transmit the second information to base station, it is to be used to indicate first resource which, which is used to indicate the first information, Subset is still used to indicate Secondary resource subset.

In another example, base station can be according to the first information that the busy ratio CBR instruction UE of channel is sent for referring to Show first resource subset or Secondary resource subset.If channel is relatively busy, i.e., assignable resource is less, then instruction UE in base station is sent The first information be used to indicate first resource subset；If channel is more idle, i.e., assignable resource is more, then base station instruction UE hair The first information sent is used to indicate Secondary resource subset, to reduce the bit number of first information occupancy, effectively save uplink is passed Defeated resource.

A kind of optional scheme, the first resource subset include assignable time-domain resource in the running time-frequency resource, institute Stating Secondary resource subset includes indistributable time-domain resource in the running time-frequency resource.In one example, the first information It is used to indicate the subframe of the first resource subset or the Secondary resource subset.

Another optional scheme, the first resource subset includes assignable frequency domain resource in the running time-frequency resource, The Secondary resource subset includes indistributable frequency domain resource in the running time-frequency resource.In one example, first letter Breath is used to indicate the subchannel of the first resource subset or the Secondary resource subset.

Another optional scheme, the first resource subset include in the running time-frequency resource assignable time-domain resource and Frequency domain resource, the Secondary resource subset include indistributable time-domain resource and frequency domain resource in the running time-frequency resource.One In a example, the first information is used to indicate in the subframe and subframe of the first resource subset or the Secondary resource subset Subchannel.In another example, the first information is used to indicate the first resource subset or Secondary resource Subframe in the subchannel and subchannel of collection.

Step 103, base station determines the time-domain resource and/or frequency domain resource for distributing to the UE according to the first information.

In one example, the first information is used to indicate the first resource subset or the Secondary resource subset Subframe；The base station determines assignable subframe according to the subframe of the first resource subset or the Secondary resource subset；Institute It states base station and determines that at least one subframe distributes to the UE from the assignable subframe.According to the embodiment, base station is When UE reserves subframe, all subchannels in the subframe are kept for into the UE, it is subsequent by the UE from all sub- letters in the subframe Subchannel selected to use in road, to realize that base station scheduling realizes resource allocation with the mode that combines of UE selection, avoid with Other UE conflict.

In another example, the first information is used to indicate the first resource subset or the Secondary resource subset Subframe and subframe in subchannel；The base station is true according to the subframe of the first resource subset or the Secondary resource subset Fixed assignable subframe, and determined according to the subchannel in the subframe of the first resource subset or the Secondary resource subset Assignable subchannel in the assignable subframe；The base station determines at least one subframe from the assignable subframe Distribute to the UE, and from determining at least one subchannel distribution to institute at least one described subframe in assignable subchannel State UE.Exemplary, if distributing multiple subchannels, multiple subchannel is continuous.According to the embodiment, first letter Breath is applied not only to indicate the subframe of the first resource subset or the Secondary resource subset, is also used to indicate the first resource Subchannel in the subframe of subset or the Secondary resource subset is only used for indicating first money relative to the first information The subframe of source subset or the Secondary resource subset has received some snoop results by base station, so that the scheduling of base station is more Accurately.

In another example, the first information is used to indicate the first resource subset or the Secondary resource subset Subchannel；The base station determines assignable son according to the subchannel of the first resource subset or the Secondary resource subset Channel；The base station determines at least one subchannel distribution to the UE from the assignable subchannel.It is exemplary, if Multiple subchannels are distributed, multiple subchannel is continuous.According to the embodiment, when base station is that UE reserves subchannel, by this All subframes in subchannel keep for the UE, it is subsequent by the UE from all subframes in the subchannel son selected to use Frame avoids conflicting with other UE to realize that base station scheduling realizes resource allocation with the mode that UE selection combines.

In another example, the first information is used to indicate the first resource subset or the Secondary resource subset Subchannel and subchannel in subframe；Believed according to the son of the first resource subset or the Secondary resource subset base station Road determines assignable subchannel, and according to the son in the subchannel of the first resource subset or the Secondary resource subset Frame determines assignable subframe in the assignable subchannel；The base station determines at least from the assignable subchannel One sub-channels distribute to the UE, exemplary, if distributing multiple subchannels, multiple subchannel is continuous.And from institute It states and determines that at least one subframe distributes to the UE at least one subchannel in assignable subframe.According to the embodiment, The first information is applied not only to indicate the subchannel of the first resource subset or the Secondary resource subset, is also used to indicate Subframe in the subchannel of the first resource subset or the Secondary resource subset, is only used for referring to relative to the first information The subchannel for showing the first resource subset or the Secondary resource subset has received some snoop results by base station more, makes The scheduling for obtaining base station is more accurate.

Step 104, base station to the UE send the 6th information, the 6th information be used to indicate distribute to the UE when Domain resource and/or frequency domain resource.

In one example, the first information is used to indicate the first resource subset or the Secondary resource subset Subframe；6th information is specially the second information, and second information is used to indicate at least one son for distributing to the UE Frame；The method also includes: the UE receives the second information, and second information, which is used to indicate, distributes at least the one of the UE A subframe；The UE according to the snoop results of running time-frequency resource, determined from all subchannels at least one described subframe to A few available subchannel, at least one described subframe described at least one available subchannel transmitting data. It is exemplary, if it is determined that multiple subchannels, multiple subchannel are continuous.According to the embodiment, the first information is only used for Indicate the subframe of the first resource subset or the Secondary resource subset, which is not used in the instruction first resource The subchannel of the subframe of subset or the Secondary resource subset, correspondingly, UE receive the second information, and second information is only used for At least one subframe of the UE is distributed in instruction, which is not used at least one subframe that the UE is distributed in instruction Subchannel, that is to say, that all subchannels in these subframes are kept for into the UE, the UE distributes to oneself knowing After subframe, also to be selected at least from all subchannels at least one described subframe according to the snoop results of running time-frequency resource One available subchannel, by least one available subchannel transmission data described at least one described subframe, from And realize that base station scheduling realizes resource allocation with the mode that UE selection combines, it avoids conflicting with other UE.

In another example, the first information is used to indicate the first resource subset or the Secondary resource subset Subframe and subframe in subchannel；6th information is specially third information, and the third information, which is used to indicate, to be distributed to At least one subchannel at least one subframe of the UE and at least one described subframe；It is exemplary, if distribution is multiple Subchannel, multiple subchannel are continuous.The method also includes: the UE receives third information, and the third information is used At least one subchannel at least one subframe and at least one described subframe that the UE is distributed in instruction；The UE exists At least one described subchannel transmitting data at least one described subframe.According to the embodiment, the first information It is applied not only to indicate the subframe of the first resource subset or the Secondary resource subset, is also used to indicate first resource Subchannel in the subframe of collection or the Secondary resource subset, is only used for indicating the first resource subset relative to the second information Or the subframe of the Secondary resource subset, so that the third information that UE is received is more accurate, the third information is applied not only to refer to Show at least one subframe for distributing to the UE, is also used to indicate at least one subchannel at least one described subframe.

In another example, the first information is used to indicate the first resource subset or the Secondary resource subset Subchannel；6th information is specially the 4th information, and the 4th information, which is used to indicate, distributes at least the one of the UE Sub-channels；The method also includes: the UE receives the 4th information, and the 4th information, which is used to indicate, distributes to the UE's At least one subchannel；Exemplary, if distributing multiple subchannels, multiple subchannel is continuous.The UE is according to time-frequency The snoop results of resource determine at least one available subframe, in institute from all subframes at least one described subchannel State at least one described available subframe transmitting data at least one subchannel.According to the embodiment, the first information It is only used for indicating the subchannel of the first resource subset or the Secondary resource subset, which is not used in described in instruction The subframe of the subchannel of first resource subset or the Secondary resource subset, correspondingly, UE receive the 4th information, the 4th letter Breath is only used at least one subchannel that the UE is distributed in instruction, and the 4th information is not used in instruction and distributes to the UE extremely The subframe of few sub-channels, that is to say, that all subframes in these subchannels are kept for into the UE, the UE is being known point It, will also all sons according to the snoop results of running time-frequency resource, from least one described subchannel after the subchannel of dispensing oneself At least one available subframe is selected in frame, is passed by least one available subframe described at least one described subchannel Transmission of data avoids conflicting with other UE to realize that base station scheduling realizes resource allocation with the mode that UE selection combines.

The present invention is introduced in more detail below by specific embodiment, and in the embodiment, UE, which is reported, to be used to indicate The information of first resource subset.The first money is used to indicate since UE reports the information for being used to indicate Secondary resource subset and UE to report The information of source subset, treatment process is similar, therefore subsequent repeats no more.

Scheme one: UE reports time domain snoop results

In one example, UE reports assignable M subframe, wherein M >=1.The M subframe constitutes first resource Collection.

A kind of screening principle of assignable subframe:

In one example, the ratio of the number for the subchannel for including in the number and subframe of assignable subchannel in subframe Value is greater than or equal to P%, for example, P=80, special P=100.Wherein, P% can be understood as pre-determined first threshold.

The resource collection of monitoring can be as shown in Figure 2: the resource collection includes 7 subframes, includes 5 sons in each subframe Channel has the grid of filling to represent idling-resource, i.e. subchannel in the subframe is not occupied by UE.From figure 2 it can be seen that The subframe has 4 idle sub-channels, and total number of subchannels is 5, then ratio is 80%, that is, meets subframe screening principle, and UE is reported The subframe is indicated or is indexed using bitmap (bitmap) (index) and indicate, here without limitation.

After base station receives the snoop results of UE, resource allocation can be carried out according to the snoop results.

In one example, if P is less than 100, illustrate there are some subchannels occupied in the subframe.Base station is from UE A subframe is distributed in the subframe of report to UE, and reserves this subframe, i.e., the subframe cannot distribute to other UE (such as mode 3UE), UE, according to snoop results, selects N number of subchannel to send data, wherein N >=1 from the subframe that base station is distributed.Example , select N number of continuous subchannel to send data, N is greater than 1.If P is larger, idle sub-channels are more, then the subframe is reserved in base station When, the resource reserved for a UE is more.

In another example, if P is equal to 100, i.e., there is no subchannel occupied in the subframe.The son that base station is reported from UE The running time-frequency resource of N number of subchannel in a subframe is distributed in frame to UE, and only reserves N number of subchannel, and UE is according to base station point The running time-frequency resource matched sends data, N >=1.Exemplary, the N number of continuous subchannel distributed in a subframe sends data, and N is greater than 1。

P can be it is predefined, be semi-statically configured or dynamic instruction.

Optionally, it is adjusted according to the occupation condition in Current resource pond, such as P can receive signal with sidelink Intensity indicates (Sidelink Received Signal Strength Indicator, S-RSSI) or the busy ratio of channel (ChannelBusy Ratio, CBR) is associated, has certain corresponding relationship, for example, CBR=80%, P=30%；CBR= 20%, P=80%, the corresponding relationship can be provided by (pre-) configuration of network or standard.

Optionally, the business reorganization currently to be sent according to UE, for example, P can with close on traffic packets priority (ProSePer-Packet Priority, PPPP) is associated, has certain corresponding relationship, for example, Priority=0, P= 50%；Priority=5, P=80%, wherein Priority represents service priority, is exactly the value of PPPP, and 0 to represent business excellent First grade is relatively high, and 1 to represent service priority lower than 0, and so on, PPPP has 8 values altogether, and from 0 to 7, which can be with Pass through (pre-) configuration of network or standard regulation.

Optionally, multiple optional P values are configured, UE can select a P value according to situation is monitored, if optional set neutron Frame number is fewer (for example, being less than Mmin), then reduces one smaller P value of P value or selection and reselect optional subframe Set sends corresponding optional sub-frame set until number of subframes is greater than or equal to Mmin in optional set.

In one example, if P value includes 100,1 bit (bit) signals base is used, whether P value is 100.

Another screening principle of distributable subframe:

In one example, the ratio of the number for the subchannel for including in the number and subframe of assignable subchannel in subframe Value is greater than 0 and is less than or equal to Q%, such as Q=20.Wherein, Q% can be understood as aforementioned second threshold.Illustrate the subframe In, the number of available subchannel is less.A subframe is distributed to UE in base station from the subframe that UE is reported, and reserves this height Frame, the i.e. subframe cannot distribute to other UE (such as mode 3UE), and UE is from the subframe that base station is distributed, according to snoop results, choosing It selects N number of subchannel and sends data, wherein N >=1.It is exemplary, select N number of continuous subchannel to send data, N is greater than 1.If Q compared with Small, idle sub-channels are less, then when the subframe is reserved in base station, the resource reserved for a UE is less, can there is more resources Distribute to other UE.

Q can be it is predefined, be semi-statically configured or dynamic instruction.

Optionally, according in Current resource pond occupation condition adjust, such as Q can and S-RSSI CBR phase Association, there is certain corresponding relationship, which can be provided by (pre-) configuration of network or standard.

Optionally, the business reorganization currently to be sent according to UE, such as Q can be associated with PPPP, there is certain correspondence Relationship, the corresponding relationship can be provided by (pre-) configuration of network or standard.

Optionally, multiple selectable value are configured, UE can select a Q value according to situation is monitored, if optional sub-frame set Middle number of subframes is fewer (being, for example, less than Mmin), then expands one bigger Q value of Q value or selection and reselect optional son Frame set sends corresponding optional sub-frame set until number of subframes is greater than or equal to Mmin in optional sub-frame set.

Another screening principle of assignable subframe:

In one example, the number of subframes in the sub-frame set of screening is greater than or equal to Mmin, i.e. M is more than or equal to Mmin, wherein Mmin can be understood as aforementioned third threshold value.

The screening principle can be concomitant regimen with two screening principles before, or two screening principles before Supplement rule.

For example, when UE uses the screening principle, according to snoop results, by the subframe of available free resource according to wherein idle son The number of frame resource is according to from small to large or sorting from large to small, and M subframe reports before choosing, and wherein M is more than or equal to Mmin.

In one example, a subframe is distributed to UE in base station from the subframe that UE is reported, and reserves this subframe, i.e., should Subframe cannot distribute to other UE (such as mode 3UE)；UE, according to snoop results, selects N number of son from the subframe that base station is distributed Channel sends data, and N is more than or equal to 1.It is exemplary, select the subchannel of N number of connection to send data, N is greater than 1.

In one example, UE reports available subchannel in distributable M subframe and the M subframe.

The resource collection of monitoring can be as shown in Figure 3: having the grid of filling to represent idling-resource in Fig. 3, UE reports this While subframe, the position (position for having the grid of filling) of subchannel idle in the subframe is also reported, bitmap is used (bitmap) (index) instruction is indicated or indexes, here without limitation.

The screening principle of assignable subframe can be using any one in aforementioned screening principle:

Optionally, the ratio of the number for the subchannel for including in the number and subframe of assignable subchannel in subframe is greater than Or it is equal to P%, for example, P=80, special P=100.

Optionally, the ratio of the number for the subchannel for including in the number and subframe of assignable subchannel in subframe is less than Or it is equal to Q%, such as Q=20.

Optionally, the number of subframes in the sub-frame set of screening is greater than or equal to Mmin, i.e. M is more than or equal to Mmin.

Since UE has reported available subchannel in the subframe, then base station is distributed N number of from the available subchannels that UE is reported The running time-frequency resource of subchannel only reserves N number of subchannel to UE.UE sends data according to the running time-frequency resource that base station is distributed.This In example, UE has reported some snoop results more, so that the scheduling of base station is more accurate.

It is the scheme for reporting time domain snoop results above, similar, the embodiment of the present invention, which also proposed, reports frequency domain dimension Snoop results scheme.

Scheme two: UE reports frequency domain snoop results

In one example, UE reports distributable M sub-channels.The M sub-channels constitute first resource subset.

A kind of screening principle of assignable subchannel:

In one example, the ratio of the number for the subframe for including in the number and subchannel of assignable subframe in subchannel Value is greater than or equal to P%, for example, P=80, special P=100.Wherein, P% can be understood as aforementioned 5th threshold value.

The resource collection of monitoring can be as shown in Figure 4: the resource collection includes 7 subframes, includes 5 sons in each subframe Channel has the grid of filling to represent idling-resource, i.e. subframe in the subchannel is not occupied by UE.Figure 4, it is seen that There are 6 idle subframes in the subchannel, total number of sub frames is 7, then ratio is greater than 80%, that is, meets subchannel screening principle, UE The subchannel is reported, (index) is indicated or indexed using bitmap (bitmap) and is indicated, here without limitation.

In one example, assignable subframe needs to meet the delay requirement of business in subchannel here, for example, son letter Assignable subframe needs between T1 and T2 in road, and T1 and T2 are respectively time threshold, and T2 is greater than T1, and T1 is more than or equal to 0.

In one example, if P is less than 100, illustrate there are some subframes occupied in the subchannel.Base station is from UE N number of subchannel is distributed in the subchannel of report to UE, and reserves this N number of subchannel, i.e., N number of subchannel cannot distribute to other UE (such as mode 3UE), N >=1.It is exemplary, it distributes N number of continuous subchannel and sends data, N is greater than 1.UE distributes N number of from base station In subchannel, according to snoop results, one of subframe is selected to send data.It is understood that N number of subchannel of distribution exists The subframe is idle, if N number of subchannel of distribution does not have idle subframe, UE can choose wherein M sub-channels and M The idle subframe of sub-channels, M is more than or equal to 1, and M is less than or equal to N.If P is larger, indicate that idle subframe is more, then When N number of subchannel is reserved in base station, the resource reserved for a UE is more.

In another example, if P is equal to 100, i.e., there is no subframe occupied in the subchannel.The son that base station is reported from UE The running time-frequency resource of a subframe in N number of subchannel is distributed in channel to UE, and only reserves N number of subchannel in the subframe, UE Data, N >=1 are sent according to the running time-frequency resource of base station distribution.Exemplary, the N number of continuous subchannel distributed in a subframe is sent Data, N are greater than 1.

Optionally, according in Current resource pond occupation condition adjust, such as P can and S-RSSI CBR phase Association, there is certain corresponding relationship, which can be provided by (pre-) configuration of network or standard.

Optionally, the business reorganization currently to be sent according to UE, such as P can be associated with PPPP, there is certain correspondence Relationship, the corresponding relationship can be provided by (pre-) configuration of network or standard.

Optionally, multiple optional P values are configured, UE can select a P value according to situation is monitored, if optional set neutron Channel number is fewer (for example, being less than Mmin), then reduces one smaller P value of P value or selection and reselect optional son Channel set sends corresponding optional sets of sub-channels until optional set sub-channels number is greater than or equal to Mmin.

Another screening principle of assignable subchannel:

In one example, the ratio of the number for the subframe for including in the number and subchannel of assignable subframe in subchannel Value is less than or equal to Q%, such as Q=20.Wherein, Q% can be understood as aforementioned 6th threshold value.Here assignable in subchannel Subframe needs to meet the delay requirement of business, and assignable subframe needs between T1 and T2 in subchannel, and T1 and T2 are respectively Time threshold, T2 are greater than T1, and T1 is more than or equal to 0.Illustrate in the subchannel, available number of sub-frames is less.Base station is reported from UE Subchannel in distribute N number of subchannel to UE, and reserve this N number of subchannel, i.e., N number of subchannel cannot distribute to other UE. UE, according to snoop results, selects a subframe to send data, wherein N >=1 from N number of subchannel that base station is distributed.It is exemplary, N number of continuous subchannel is selected to send data, N is greater than 1.If Q is smaller, idle subframe is less, then N number of subchannel is reserved in base station When, the resource reserved for a UE is less, can have more resource allocations to other UE.

Optionally, multiple selectable value are configured, UE can select a Q value according to situation is monitored, if optional sub-frame set Middle number of subframes is fewer (being, for example, less than Mmin), then expands one bigger Q value of Q value or selection and reselect optional son Channel set sends corresponding optional subchannel until optional sets of sub-channels sub-channels number is greater than or equal to Mmin Set.

Another screening principle of assignable subchannel:

In one example, the subchannel number in the sets of sub-channels of screening is greater than or equal to Mmin, i.e. M is more than or equal to Mmin, wherein Mmin can be understood as aforementioned 7th threshold value.

For example, when UE uses the screening principle, according to snoop results, by the subchannel of available free resource according to wherein idle The number of sub-channel resource is according to from small to large or sorting from large to small, and M sub-channels report before choosing, and wherein M is greater than etc. In Mmin.

Here assignable subframe needs to meet the delay requirement of business in subchannel, for example, assignable in subchannel Subframe needs between T1 and T2, and T1 and T2 are respectively time threshold, and T2 is greater than T1, and T1 is more than or equal to 0.

In one example, N number of subchannel is distributed to UE in base station from the subchannel that UE is reported, and reserves this N number of sub- letter Road, i.e. N number of subchannel cannot distribute to other UE.UE is from N number of subchannel that base station is distributed, according to snoop results, selection One subframe sends data, and N is more than or equal to 1.It is exemplary, select the subchannel of N number of connection to send data, N is greater than 1.

In one example, UE reports available subframe on assignable M sub-channels and the M sub-channels.

The resource collection of monitoring can be as shown in Figure 5: having the grid of filling to represent idling-resource in Fig. 5, UE reports this While subchannel, the position (position for having the grid of filling) of subframe idle in the subchannel is also reported, bitmap is used (bitmap) (index) instruction is indicated or indexes, here without limitation.

The screening principle of assignable subchannel can be using any one in aforementioned screening principle:

Optionally, the ratio of the number for the subframe for including in the number and subchannel of assignable subframe in subchannel is greater than Or it is equal to P%, for example, P=80, special P=100.

Optionally, the ratio of the number for the subframe for including in the number and subchannel of assignable subframe in subchannel is less than Or it is equal to Q%, such as Q=20.

Optionally, the number of the subchannel in the sets of sub-channels of screening is greater than or equal to Mmin, i.e. M is more than or equal to Mmin。

Since UE has reported available subframe in the subchannel, then N number of son is distributed from the available subframe that UE is reported in base station The running time-frequency resource of the corresponding subframe of channel only reserves N number of subchannel in the subframe to UE.UE is distributed according to base station Running time-frequency resource sends data.In this example, UE has reported some snoop results more, so that the scheduling of base station is more accurate.

In the embodiment of the present invention, UE only reports the snoop results of part or a dimension, to reduce the bit reported Number, reduction report required ascending resource.
