Specific embodiment

Resource regulating method, user equipment and base station according to an embodiment of the present invention described below with reference to accompanying drawings.? In attached drawing, identical reference label indicates identical element from beginning to end.It is understood that the embodiments described herein is only to say Bright property, and be not necessarily to be construed as limiting the scope of the invention.

In a communications system, it is contemplated that the tradeoff of the signaling cost and overall transfer performance of the information transmission of V2X provides Resource distribution and dispatching method as described in the embodiments of the present invention, base station and user equipment.

Specifically, the embodiment of the present invention provides a kind of resource regulating method, and the method is executed by UE.Fig. 1 shows basis The flow chart of the resource regulating method 100 of the embodiment of the present invention.

As shown in Figure 1, in step s101, receiving the scheduling information that base station is sent, the scheduling information is used to indicate institute State the running time-frequency resource for being used to carry out information transmission that base station is UE scheduling, the running time-frequency resource of the UE and the time-frequency of other UE Resource is orthogonal or nonopiate.

In embodiments of the present invention, base station carries out the running time-frequency resource of information transmission by scheduling UE, to generate the UE's Scheduling information, and instruction base station is sent by the scheduling information of the UE running time-frequency resource distributed to the UE.Optionally, the time-frequency money Source can be physical resource.

Optionally, UE can send relevant information so that base station is accordingly scheduled the UE to base station first.For example, UE can send the geographical location information and/or channel large-scale fading information of the UE to base station, so that base station is according to the UE Geographical location information and/or channel large-scale fading message scheduling described in UE running time-frequency resource, generate scheduling information.The letter Road large-scale fading information can be, for example, the large-scale fading letter of the uplink and/or descending transmission channel between UE and base station Breath.Specifically, base station can directly carry out running time-frequency resource scheduling according to the geographical location information that UE is reported；It can also be according on UE The geographical location information of report channel large-scale fading information calculated, or the channel large scale that the UE that directly receives is reported decline It falls information and carries out running time-frequency resource scheduling；The geographical location information and channel large-scale fading letter that UE is reported can also be comprehensively considered Breath is to carry out running time-frequency resource scheduling.

In one example, base station is the time-frequency money that the running time-frequency resource of the UE distribution can be other UE distribution with base station Source is completely orthogonal；In another example, it can be some or certain UE with base station that base station, which is the running time-frequency resource of the UE distribution, The running time-frequency resource of distribution is nonopiate.When the running time-frequency resource and base station that base station is the UE distribution are the running time-frequency resource that other UE are distributed When orthogonal, since the UE and other UE will not be interfered with each other when information is sent, the quality of information transmitted by UE is preferable, But channel resource utilization rate is lower；And when the time-frequency that the running time-frequency resource and base station that base station is the UE distribution are other UE distribution provides It when source is nonopiate, then may meet as far as possible the capacity gain of system while meeting certain information transmission quality, improve letter Road resource utilization.

In one example, when the time-frequency money that the running time-frequency resource and base station that base station is UE distribution are some or certain UE distribution When source is nonopiate, then it will appear one or more UE matching pair that identical running time-frequency resource is assigned by base station.Base station it is non-just It hands under resource allocation conditions between when the matching for carrying out identical running time-frequency resource UE, can be matched on time slot first, then Matching frequency resource again.Wherein, when matching time slot, it is contemplated that each UE tends to select other UE shapes farther away from itself It avoids potentially colliding at pairing, so that the cross influence of communication coverage of the UE matching between is minimum, it therefore, can By by aforementioned UE send such as geographical location information because usually calculate UE match to the best match on time slot in the way of. Further optionally, a pair of of UE that distance between UE is less than certain threshold value can also be set as forbidding pair, when UE matching is to calculating Excluding these forbids the time slot between to match, to reduce the interference of interchannel as much as possible.Then, in the matched process of frequency In, base station is it is further contemplated that the channel large-scale fading information that such as UE is reported or the geographical location information reported according to UE The channel large-scale fading information of calculating, so that cochannel cross jamming of the UE in frequency domain channel on identical time slot is calculated, To adjust the matching result of UE matching pair, the UE matching pair on final identical running time-frequency resource is obtained.

Optionally, UE the scheduling information that sends of received base station can be sent out in a manner of semi-persistent scheduling (SPS) for base station The scheduling information sent.In SPS scheduling information, dispatching cycle can be relatively long, for example, a few tens of milliseconds, several hundred milliseconds or several Second, to mitigate the signalling burden between base station and UE as far as possible.Optionally, the received scheduling information of UE institute not only may include The running time-frequency resource scheduling information of UE transmitted by base station can also include UE number on such as identical running time-frequency resource, for UE The UE mark of detection, UE are used to send the weight of the initial power of information, transmission timer/counter of SPS scheduling information, UE The factor, UE transmission priority one or more of, wherein the weight factor UE can be assisted to execute with next or The multiple functions of person, the transmission power adjustment including UE, transmission rate adjustment of UE etc..In addition, above-mentioned scheduling information is specific interior Appearance can be pre-configured with UE by base station, and be controlled by base station partly or entirely to activate these configurations, can also believe It enables in transmission process and is sent immediately by base station to inform UE.

In step s 102, UE determines the power for carrying out information transmission.

Fig. 2 shows the flow charts that determining information according to an embodiment of the present invention sends the method 102 of power.As shown in Fig. 2, In step sl, reference signal is broadcasted using the running time-frequency resource of scheduling information instruction.Specifically, when UE receives base station hair After the scheduling information for the instruction time-frequency resource allocating sent, it can be referred to according to the running time-frequency resource that the scheduling information indicates Signal broadcast, so that other UE without using the running time-frequency resource are received and carried out the calculating of cochannel interference.Optionally, it is described not All reference signals broadcasted by the running time-frequency resource received can be carried out with letter using other UE of the running time-frequency resource Road interference calculation can also carry out cochannel interference meter by the reference signal that the running time-frequency resource is broadcasted to a part received It calculates.Wherein, described other UE without using the running time-frequency resource can use measured SINR (Signal to Interference plus Noise Ratio), RSRP (reference Signal reception power), the parameters such as RSSI (receive signal energy instruction) or RSRQ (Reference Signal Received Quality) calculate Cochannel interference on the running time-frequency resource.Result through the above-mentioned cochannel interference being calculated can partly or entirely be fed back To the UE.

In step s 2, the cochannel interference fed back without using other UE of the running time-frequency resource is received, wherein described same Channel disturbance is based respectively on the received reference signal on its running time-frequency resource by other described UE and is calculated.In this step In, the UE can be fed back to without using all or part of feedback result of other UE institute of the running time-frequency resource, it is certainly, above-mentioned anti- Feedback result can also be fed back to one or more UE that the identical running time-frequency resource is used with the UE by other UE.

In step s3, it is interfered based on the cochannel and determines the power for carrying out information transmission.In one example, described UE tends to that suitable information is selected to send power so that cochannel interference is small as far as possible.In addition, UE is also tended to herein On the basis of select power small as far as possible farthest to avoid the cross influence between multiple UE, therefore, determined in the UE During the power for carrying out information transmission, various parameters included by aforementioned scheduling information or signaling can also be further considered Instruction.For example, the weight factor that base station is sent in scheduling information can be considered to adjust the power that the information is sent in UE.? In one example, the base station can be by distributing weight factor to the UE to guarantee the information sent for receiving each UE The information of one or more UE receive the decode effect, it is alternatively possible to guarantee around the UE that weighted value is X, at least UE more than 100X% can be received and the information of this UE transmission is successfully decoded.In another example, the weight factor is also The priority attributes of the UE in a communications system can be represented, to ensure that the higher UE of priority there can be higher communication Quality, so that the higher UE of weight factor, which may can choose higher power, carries out information transmission.In one example, weight The value of the factor can be the arbitrary value between 0 to 1.In addition, the UE determines that the period for the power that information is sent can be opposite It is shorter in the period for the SPS scheduling information that base station is sent, such as can be 10ms, 20ms or 100ms, in order to which UE is controlled in time System and adjustment information send power, improve communication quality.

Fig. 3 shows base station transmission scheduling information and UE in the communication system of the embodiment of the present invention and determines that information sends power Timing diagram.As shown in figure 3, the communication system includes base station and UE1-UE4.Wherein, in (1) and (2), UE1 and UE2 divide Not to base station reporting scheduling request, and its geographical location information and/or channel large-scale fading information can be reported together.Base station After receiving the information that UE1 and UE2 are reported, be assigned with mutual non-orthogonal running time-frequency resource for UE1 and UE2, and in (3) and (4) it is indicated respectively by scheduling information to UE1 and UE2 in.In period shown in Fig. 3, UE3 and UE4 not by base station distribution with The non-orthogonal running time-frequency resource of UE1 and UE2 namely UE3 and UE4 do not use the running time-frequency resource of UE1 and UE2.UE1 and UE2 is being received After the running time-frequency resource scheduling information sent to base station, distributed running time-frequency resource is utilized respectively to UE3 and UE4 broadcast with reference to letter Number ((5)-(8)).Then, using it, the received reference signal respectively from UE1 and UE2 in (5) and (7) calculates together UE3 Channel disturbance, and UE1 and UE2 are fed back to respectively in (9) and (10)；And UE4 utilizes its received difference in (6) and (8) Reference signal from UE1 and UE2 calculates cochannel interference, and feeds back to UE1 and UE2 respectively in (11) and (12).Finally, UE1 determines what information was sent by the feedback of its cochannel interference respectively from UE3 and UE4 received in (9) and (11) Power, optionally, the weight factor for the UE1 that UE1 is also conceivable in scheduling information transmitted by base station are determined to adjust it Power.UE2 determines letter by the feedback of its cochannel interference respectively from UE3 and UE4 received in (10) and (12) The power sent, optionally, of course, UE2 are ceased it is also contemplated that the weight factor of the UE1 in scheduling information transmitted by base station is come Adjust its identified power.In addition, UE1 or UE2 can also consider the feedback of UE3 or UE4 only to determine the function of information transmission Rate.

In step s 103, information hair is carried out using the running time-frequency resource that identified power and the scheduling information indicate It send.

In this step, the running time-frequency resource and independently determining information that UE is determined using base station send power in its communication model Enclose interior transmission information.Optionally, UE can use the running time-frequency resource that base station determines and the information independently determined sends power and pass through UE-UE direct connected link sends information.In addition, UE can also be when receiving scheduling information, using included in the scheduling information Base station be that the initial transmission power of UE setting sends current information and reference signal simultaneously, and followed by receive other The cochannel that UE is fed back according to the reference signal interferes the transmission power to determine next information, and row information of going forward side by side is sent.

Using the resource regulating method executed according to the present invention by UE, UE is enabled to carry out the running time-frequency resource of information transmission It is determined by base station, and the transmission power of UE is independently determined by UE, to effectively reduce UE to UE direct connected link (SL) Signaling cost improves the channel resource utilization rate of system, reduces the wasting of resources.

The embodiment of the present invention also provides a kind of resource regulating method, and the method is executed by base station.Fig. 4 is shown according to this hair The flow chart of the resource regulating method 400 of bright embodiment.

As shown in figure 4, scheduling UE carries out the running time-frequency resource of information transmission, so that the time-frequency of the UE in step S401 Resource is orthogonal or nonopiate with the running time-frequency resource of other UE.

In embodiments of the present invention, it can be physical resource that scheduling UE in base station, which carries out the running time-frequency resource of information transmission,.It is optional Ground, UE can send relevant information so that base station is accordingly scheduled the UE to base station first.For example, UE can be to base station The geographical location information and/or channel large-scale fading information of the UE are sent, so that base station is believed according to the geographical location of the UE The running time-frequency resource of UE described in breath and/or channel large-scale fading message scheduling generates scheduling information.The channel large-scale fading Information can be, for example, the large-scale fading information of the uplink and/or descending transmission channel between UE and base station.Specifically, base station Running time-frequency resource scheduling can be directly carried out according to the geographical location information that UE is reported；It can also be believed according to the geographical location that UE is reported Channel large-scale fading information calculated is ceased, or the channel large-scale fading information that the UE directly received is reported carries out time-frequency Scheduling of resource；Geographical location information and the channel large-scale fading information that UE is reported can also be comprehensively considered to carry out time-frequency money Source scheduling.

In one example, when the time-frequency money that the running time-frequency resource and base station that base station is UE distribution are some or certain UE distribution When source is nonopiate, then it will appear one or more UE matching pair that identical running time-frequency resource is assigned by base station.Base station it is non-just It hands under resource allocation conditions between when the matching for carrying out identical running time-frequency resource UE, can be matched on time slot first, then Matching frequency resource again.Wherein, when matching time slot, it is contemplated that each UE tends to select other UE shapes farther away from itself It avoids potentially colliding at pairing, so that the cross influence of communication coverage of the UE matching between is minimum, it therefore, can By by aforementioned UE report such as geographical location information because usually calculate UE match to the best match on time slot in the way of. Further optionally, a pair of of UE that distance between UE is less than certain threshold value can also be set as forbidding pair, when UE matching is to calculating Excluding these forbids the time slot between to match, to reduce the interference of interchannel as much as possible.Then, in the matched process of frequency In, base station is it is further contemplated that the channel large-scale fading information that such as UE is reported or the geographical location information reported according to UE The channel large-scale fading information of calculating, so that cochannel cross jamming of the UE in frequency domain channel on identical time slot is calculated, To adjust the matching result of UE matching pair, the UE matching pair on final identical running time-frequency resource is obtained.

In the following, describing base station according to an embodiment of the invention referring to Fig. 6.Fig. 6 is to show according to the present invention one The block diagram of the base station 600 of a embodiment.As shown in fig. 6, base station 600 includes scheduling unit 610 and transmission unit 620.In addition to this 2 Other than a unit, base station 600 can also include other component, however, due to the content of these components and the embodiment of the present invention without It closes, therefore omits its diagram and description herein.Further, since following behaviour that base station 600 according to an embodiment of the present invention executes The detail of work is identical as the details described above with reference to Fig. 4, therefore omits herein in order to avoid repeating to phase With the repeated description of details.

As shown in fig. 6, scheduling unit 610 dispatches the running time-frequency resource that UE carries out information transmission, so that the time-frequency of the UE provides Source is orthogonal or nonopiate with the running time-frequency resource of other UE.

In embodiments of the present invention, scheduling unit 610, which dispatches UE and carries out the running time-frequency resource of information transmission, to be physics money Source.Optionally, UE can send relevant information so that the scheduling unit 610 of base station accordingly adjusts the UE to base station first Degree.For example, UE can send the geographical location information and/or channel large-scale fading information of the UE to base station, so that scheduling is single The running time-frequency resource of 610 UE according to the geographical location information of the UE and/or channel large-scale fading message scheduling of member generates Scheduling information.The channel large-scale fading information can be, for example, the uplink and/or descending transmission channel between UE and base station Large-scale fading information.Specifically, scheduling unit 610 can directly carry out time-frequency money according to the geographical location information that UE is reported Source scheduling；The geographical location information that can also be reported according to UE channel large-scale fading information calculated, or directly receive The channel large-scale fading information that reports of UE carry out running time-frequency resource scheduling；The geographical location letter that UE is reported can also be comprehensively considered Breath and channel large-scale fading information carry out running time-frequency resource scheduling.

In one example, it can be other UE distribution with base station that scheduling unit 610, which is the running time-frequency resource of UE distribution, Running time-frequency resource it is completely orthogonal；In another example, scheduling unit 610 is that the running time-frequency resource of UE distribution can be with base station The running time-frequency resource distributed for some or certain UE is nonopiate.When the running time-frequency resource and base station that scheduling unit 610 is UE distribution When orthogonal for the running time-frequency resource of other UE distribution, since the UE and other UE will not be interfered with each other when information is sent, UE The quality of transmitted information is preferable, but channel resource utilization rate is lower；And when the time-frequency that scheduling unit 610 is UE distribution It, then may be while meeting certain information transmission quality when resource and base station are that the running time-frequency resource of other UE distribution is nonopiate The capacity gain for meeting system as far as possible, mentions high channel resource use ratio.

In one example, when the running time-frequency resource and base station that scheduling unit 610 is UE distribution are some or certain UE distribution Running time-frequency resource it is nonopiate when, then will appear scheduled unit 610 be assigned identical running time-frequency resource one or more UE matching It is right.It, can be first in scheduling unit 610 between when the matching for carrying out identical running time-frequency resource UE under non orthogonal resources distribution condition It is matched on time slot, then matching frequency resource again.Wherein, when matching time slot, it is contemplated that each UE tends to select It avoids potentially colliding farther away from other UE formation pairing of itself, so that the UE matches the communication coverage between Cross influence it is minimum, therefore, can use that aforementioned UE reports matches pair such as geographical location information because usually calculating UE Best match mode on time slot.Further optionally, a pair of of UE that distance between UE is less than certain threshold value can also be set as prohibiting Only pair, to forbid the time slot between match to excluding these when calculating in UE matching, to reduce doing for interchannel as much as possible It disturbs.Then, during frequency is matched, scheduling unit 610 is it is further contemplated that the channel large scale that such as UE is reported declines The channel large-scale fading information for falling information or being calculated according to the geographical location information that UE is reported, to calculate on identical time slot Cochannel cross jamming of the UE in frequency domain channel obtains final identical time-frequency money to adjust the matching result of UE matching pair UE matching pair on source.

Transmission unit 620 sends scheduling information to the UE, and it is the UE that the scheduling information, which is used to indicate the base station, The running time-frequency resource of scheduling, so that the UE carries out letter using the running time-frequency resource that independently determining power and the scheduling information indicate Breath is sent.

Optionally, the scheduling information that transmission unit 620 is sent can be sent in a manner of semi-persistent scheduling (SPS).It is dispatched in SPS In information, dispatching cycle can be relatively long, for example, a few tens of milliseconds, several hundred milliseconds or several seconds, to mitigate base station and UE as far as possible Between signalling burden.Optionally, transmission unit 620 to the scheduling information that UE is sent not only may include transmitted by base station UE running time-frequency resource scheduling information, can also include such as identical running time-frequency resource on UE number, for UE detect UE mark Know, UE is used to send the initial power of information, transmission timer/counter of SPS scheduling information, the weight factor of UE, UE One or more of transmission priority, wherein the weight factor can assist UE to execute one or more following function Can, the transmission power adjustment including UE, transmission rate adjustment of UE etc..In addition, the particular content of above-mentioned scheduling information can be by Base station is pre-configured with UE, and is controlled by base station partly or entirely to activate these configurations, can also be in signalling mistake It is sent immediately by base station to inform UE in journey.

In step s3, it is interfered based on the cochannel and determines the power for carrying out information transmission.In one example, described UE tends to that suitable information is selected to send power so that cochannel interference is small as far as possible.In addition, UE is also tended to herein On the basis of select power small as far as possible farthest to avoid the cross influence between multiple UE, therefore, determined in the UE During the power for carrying out information transmission, various parameters included by aforementioned scheduling information or signaling can also be further considered Instruction.For example, the weight factor that base station is sent in scheduling information can be considered to adjust the power that the information is sent in UE.? In one example, the base station can be by distributing weight factor to the UE to guarantee the information sent for receiving each UE The information of one or more UE receive the decode effect, optionally, base station can guarantee around the UE that weighted value is X, until Rare is more than the information that the UE of 100X% can receive and be successfully decoded this UE transmission.In another example, the weight because Son can also represent the priority attributes of the UE in a communications system, to ensure that it is higher that the higher UE of priority can have Communication quality, so that the higher UE of weight factor, which may can choose higher power, carries out information transmission.In one example, The value of weight factor can be the arbitrary value between 0 to 1.In addition, the UE determines that the period for the power that information is sent can be with The period of SPS scheduling information relative to base station transmission is shorter, such as can be 10ms, 20ms or 100ms, in order to which UE is timely Ground control and adjustment information send power, improve communication quality.
