Embodiment
Resource regulating method provided by the invention, as shown in Figure 1, mainly comprise following step:
S10, base station receive the transmission capability information that UE reports;
S20, base station are implemented scheduling of resource according to said transmission capability information to said UE.
Like this, the base station is through obtaining the transmission capability information of subscriber equipment, and Resources allocation that can be meticulousr can improve the service efficiency of interface-free resources; Simultaneously because the reduction of subscriber equipment disposal ability can significantly reduce its cost.
For making the object of the invention, technical scheme and advantage clearer, below lift embodiment and with reference to accompanying drawing, to further explain of the present invention.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Embodiment one
In long evolving system, some subscriber equipmenies of implementing to detect need the frequent measurement report to network side transmission small data quantity, and such as whenever reporting the one-shot measurement data at a distance from 5 minutes needs, speed only needs 10 kilobits/second.If these subscriber equipmenies adopt the hardware and software that satisfies existing protocol regulation demand; The cost of these subscriber equipmenies can be very high; The message transmission rate that these subscriber equipmenies can reach also will be considerably beyond its actual demand; This not only wastes manufacturing cost, and is unfavorable for that network side is directed against these subscriber equipmenies and takes resource scheduling algorithm efficiently, causes the waste of interface-free resources.
To the problems referred to above; Present embodiment proposes a kind of new subscriber equipment; This subscriber equipment has adopted the process chip than low rate, the signaling on the monitoring PDCCH that it can not be continuous, and a sub-frame is (in the LTE system at interval; One sub-frame equals 1 millisecond; Existing protocol regulation is in the subscriber equipment of connection status need monitor the signaling on PDCCH in each subframe, so that detect one's own PDCCH signaling) or a plurality of subframe could continue the signaling on the reception PDCCH, the flow process of its access network is as shown in Figure 2:
Step 101, subscriber equipment resident sub-district initiate to insert at random, Radio Resource control (RRC) connection request (Connection Request) signaling is sent in the base station under this sub-district.
In the present embodiment, subscriber equipment carries time domain disposal ability information in the RRC connection request, and pointer is to the disposal ability information of PDCCH here, and this need increase cell newly and represent time domain disposal ability information in the RRC connection request.
In the present embodiment; Time domain disposal ability information is meant that this subscriber equipment needs interval one sub-frame to monitor the PDCCH signaling or at interval a plurality of subframes are monitored the PDCCH signaling; Perhaps monitor the PDCCH signaling in the odd number subframe; Perhaps monitor the PDCCH signaling, promptly refer to the reception PDCCH signaling that subscriber equipment can not continue in the even number subframe.Receive the PDCCH signaling here and be meant that receiving PDCCH goes up the signaling of transmitting.
Step 102, base station are the user equipment allocation resource, send RRC to subscriber equipment and connect foundation (RRC Connection Setup) signaling.
In the present embodiment; After the time domain disposal ability information of subscriber equipment is known in the base station; Need implement scheduling of resource in view of the above to this subscriber equipment; This subscriber equipment of the scheduling that the base station can not continue needs a plurality of subframes of interval one sub-frame or interval to send a PDCCH signaling to this subscriber equipment, perhaps need send a PDCCH signaling to this subscriber equipment in odd number subframe or even number subframe.The PDCCH signaling can whenever be sent to this subscriber equipment at a distance from a sub-frame or a plurality of subframe later on again after this subscriber equipment sends the PDCCH signaling in the base station.For example; If reporting in the RRC connection request, subscriber equipment need interval 6 sub-frame could monitor the PDCCH signaling; This subscriber equipment can periodically be dispatched in the base station, as in the 1st sub-frame, the 7th sub-frame, the 13rd sub-frame, the 19th sub-frame ... Dispatch this subscriber equipment.If do not have data to send to subscriber equipment in the 7th sub-frame, then skip this sub-frame, the scheduling to subscriber equipment is still implemented according to primitive period in the base station, promptly also in the 13rd sub-frame, the 19th sub-frame ... Dispatch this subscriber equipment.Subscriber equipment can be simplified the opportunity that oneself detects the PDCCH signaling like this, avoids missing the scheduling of base station to oneself simultaneously.
Step 103; After subscriber equipment receives that RRC connects foundation; Send RRC to the base station and connect foundation completion (RRC Connection Setup Complete) signaling, this signaling also comprises the Non-Access Stratum signaling that subscriber equipment sends to core net, for example attach request or service request.
Step 104, base station are sent initial UE signaling (Initial UE Message) to core net after receiving that RRC connects foundation completion signaling, wherein comprise the Non-Access Stratum signaling, for example attach request or service request.
Step 105; After core net is received the initial UE signaling; This subscriber equipment is carried out authentication to be set up with safety; Core net is sent initial context to the base station and is set up request (Initial Context Setup Request), wherein comprises the QoS parameter of the data access bearer (Data Radio Bearer is called for short DRB) that need set up for subscriber equipment the base station, the parameter of security configuration etc.
After step 106, base station receive that initial context is set up request,, send the RRC connection to this subscriber equipment and reshuffle (RRC Connection Reconfiguration) signaling for this subscriber equipment is set up the DRB configuration parameter.
Because the base station has obtained the disposal ability information of this subscriber equipment to PDCCH in step 102; Therefore continuous dispatching is not carried out to this subscriber equipment in the base station; But last once after this subscriber equipment sends the PDCCH signaling, one or more subframes are sent the PDCCH signaling to this subscriber equipment more at interval., the RRC connection is included as the resource of this user device configuration in reshuffling; The RRC signaling need be by Physical Downlink Shared Channel (Physical Downlink Shared Channel; Be called for short PDSCH) transmission; And the position of PDSCH in frequency domain, modulation system etc. are by the PDCCH indication that is in same subframe; Subscriber equipment needs to detect one's own PDCCH signaling according to the Radio Network Temporary Identifier (Radio Network Temporary Identifier) of oneself, and the indication according to the PDCCH signaling detects the PDSCH in the same subframe then.
Step 107, subscriber equipment are used parameter configuration wherein after receiving that signaling is reshuffled in the RRC connection, send the RRC connection to the base station and reshuffle completion (RRC Connection Reconfiguration Complete) signaling.
After step 108, base station receive that completion is reshuffled in the RRC connection, send initial context to core net and set up response (Initial Context Setup Response) signaling.
So far, the smooth access network of subscriber equipment has been set up DRB with the base station, can send data to network side.
In the present embodiment, subscriber equipment has carried time domain disposal ability information in the RRC connection request, so that this subscriber equipment can reasonably be dispatched in view of the above in the base station, avoids this subscriber equipment of scheduling of continuing, causes the waste of resource.Because subscriber equipment need not possess the ability that continues to monitor the PDCCH signaling; Therefore this subscriber equipment can reduce the arithmetic speed of the frequency of processor, the memory space that reduces processor, reduction processor, and this is very favourable to the cost that reduces subscriber equipment.Simultaneously, subscriber equipment can not continue to monitor the PDCCH signaling, has also reduced its resource requirement, helps the more subscriber equipment of base station services, has increased the capacity of whole system.
Present embodiment also has other implementation; For example; Subscriber equipment does not send time domain disposal ability information to the base station in step 101, but in step 103, sends time domain disposal ability information to the base station, and this need connect to set up to accomplish in the signaling at RRC increases cell.Since the base station postpone obtained can not this subscriber equipment of continuous dispatching information; Therefore the base station maybe be for the first time when signaling be set up in this subscriber equipment transmission RRC connection (continuing to have sent the PDCCH signaling to this subscriber equipment); Cause this subscriber equipment not received; The affirmation information of subscriber equipment feedback can not received in the base station thus, so signaling will be set up to subscriber equipment transmission RRC connection once more in the base station.If the affirmation information of this subscriber equipment is not still received in the base station, the base station also will continue to send.Can find out from top process; If in step 103, send disposal ability information to the base station again about PDCCH; This subscriber equipment is set up the time that RRC connects maybe be elongated; But because the automatic repeat requests of mixing that adopt the base station (Hybrid Automatic Repeat Request is called for short HARQ) technology can be set up signaling after the base station is repeated repeatedly connecting to subscriber equipment transmission RRC of success.Consider that the business that this type of subscriber equipment is initiated is to postpone tolerance (Delay Tolerant), or be called low priority, this type subscriber equipment is postponed and set up the RRC connection is acceptable.
In the present embodiment; Time domain disposal ability information is sent through the RRC signaling; In fact also can pass through medium Access Layer (Medium Access Control is called for short MAC) control signaling and send to the base station, this need increase cell and represent in existing medium Access Layer control signaling.
In the present embodiment; Time domain disposal ability information is meant that subscriber equipment needs interval one sub-frame to monitor the PDCCH signaling or at interval a plurality of subframes are monitored the PDCCH signaling, and time domain disposal ability information can also be meant that subscriber equipment does not possess the ability information of the lasting PDSCH of reception data; Perhaps subscriber equipment receives the minimum interval of PDSCH data continuously; Perhaps subscriber equipment does not possess the ability information that continues to send signaling at PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel); Perhaps subscriber equipment does not possess the ability information that continues to send data at PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel); After the base station obtains the time domain disposal ability information of subscriber equipment, need reasonably to implement scheduling, avoid the wasting of resources, know the reception PDSCH data that subscriber equipment can not continue like the base station, between needing across sending the PDSCH data to subscriber equipment; If subscriber equipment is known and is not possessed the ability information that continues to send signaling at PUCCH that the base station can not be used in the uplink authorization (UL Grant) of signaling transmission for the branch that this subscriber equipment continues in the base station; If subscriber equipment is known and is not possessed the ability information that continues to send data at PUSCH that the base station can not be used in the uplink authorization of transfer of data for the branch that this subscriber equipment continues in the base station.
Embodiment two
In long evolving system, some subscriber equipmenies only need send and receive small data once in a while, so these subscriber equipmenies need not possess very strong disposal ability, and in the present embodiment, subscriber equipment does not possess and continues to receive the PDCCH signalling capability.The flow process of its access network is as shown in Figure 3:
Step 201, subscriber equipment resident sub-district initiate to insert at random, RRC connection request signaling is sent in the base station under this sub-district.
Step 202, base station are the user equipment allocation resource, send the RRC connection to subscriber equipment and set up signaling.
After step 203, subscriber equipment receive that RRC connects foundation, send RRC connection foundation to the base station and accomplish signaling, this signaling also comprises the Non-Access Stratum signaling that subscriber equipment sends to core net, for example, and attach request.
Step 204, base station are sent UE capability requests (UE Capability Enquiry) signaling to subscriber equipment after receiving that the RRC of subscriber equipment connects foundation completion signaling.
Because the base station finds that in step 201 this subscriber equipment does not report interim moving station mark (Temporary Mobile Station Identifier), so the unregistered mistake of this subscriber equipment of base station judges, therefore need obtain the ability information of this subscriber equipment.
Step 205; After subscriber equipment is received the capability requests signaling; To the UE ability information (UE Capability Information) that send the base station, wherein comprised the wireless access capability information of UE, comprise the Access Layer version information, radio frequency parameter information (RF parameters), type information (ue-Category) of this subscriber equipment etc.; In order to realize the present invention; Subscriber equipment newly-increased cell in the UE ability information is represented the time domain disposal ability information of this subscriber equipment, and promptly this subscriber equipment does not possess the ability that continues to monitor the PDCCH signaling, for the scheduling of assistant base station to it; The time domain disposal ability information of user equipment to report also comprises the minimum interval that continues to monitor the PDCCH signaling, can represent with sub-frame number.
Step 206, this part ability information is preserved, so that be applied to the scheduling to this subscriber equipment after obtaining the ability information of this subscriber equipment in the base station.The initial UE signaling is sent to core net in the base station, wherein comprises the Non-Access Stratum signaling, for example, and attach request.
Step 207; After core net is received the initial UE signaling; This subscriber equipment is carried out authentication set up with safety, core net is sent initial context to the base station and is set up request, wherein comprises the QoS parameter of the data access bearer DRB that need set up for subscriber equipment the base station, the parameter of security configuration etc.
After step 208, base station receive that initial context is set up request,, send the RRC connection to this subscriber equipment and reshuffle signaling for this subscriber equipment is set up the DRB configuration parameter.
Because the base station has obtained the ability information that this subscriber equipment can not continue to monitor the PDCCH signaling in step 206; Therefore continuous dispatching is not carried out to this subscriber equipment in the base station; But last once after this subscriber equipment sends the PDCCH signaling, one or more subframes (according to the minimum interval of the lasting monitoring PDCCH signaling of user equipment to report) are sent the PDCCH signaling to this subscriber equipment more at interval.
Step 209, subscriber equipment are used parameter configuration wherein after receiving that signaling is reshuffled in the RRC connection, send the RRC connection to the base station and reshuffle the completion signaling.
After step 210, base station receive that completion is reshuffled in the RRC connection, send initial context to core net and set up response (Initial Context Setup Response) signaling.
So far, the smooth access network of subscriber equipment has been set up DRB with the base station, can carry out transfer of data with network side.
Need to prove; Because the monitoring PDCCH signaling that subscriber equipment can not continue; And the base station just obtains this ability information in step 206, so the base station possibly run counter to this qualification to the RRC signaling that subscriber equipment sends in step 202 or 204, and subscriber equipment just can not receive the RRC signaling at this moment; Just can not send yet and confirm signaling to the base station; Base station (adopt existing HARQ mechanism) needs once more the RRC signaling (promptly not this subscriber equipment of continuous dispatching) in the forwarding step 202,204, receives the RRC signaling up to subscriber equipment, and the base station is received and thought after the affirmation signaling that subscriber equipment returns and send successfully.
Present embodiment also has other implementation, can be that subscriber equipment does not possess the ability information that continues to receive the PDSCH data like time domain disposal ability information; Perhaps subscriber equipment receives the minimum interval of PDSCH data continuously; Perhaps subscriber equipment does not possess the ability information that continues to send signaling in the PUCCH signaling; Perhaps subscriber equipment does not possess the ability information that continues to send data at PUSCH; After the base station obtains the time domain disposal ability information of subscriber equipment, need reasonably to implement scheduling, avoid the wasting of resources.
This enforcement also has other implementation; Identify with low speed terminal, low cost terminals or low priority terminal like time domain disposal ability information; After the sign at low speed terminal, low cost terminals or low priority terminal is received in the base station, promptly think the monitoring PDCCH signaling that subscriber equipment can not continue; Or think that subscriber equipment does not possess the ability that continues to receive the PDSCH data; Or think that subscriber equipment does not possess the ability that continues to send signaling at PUCCH, the base station is implemented the scheduling to subscriber equipment in view of the above.Agreement need be stipulated low speed terminal, low cost terminals or the pairing transmission capability information of low priority terminal iidentification; For example; The monitoring PDCCH signaling that regulation low speed terminal correspondence can not continue; Perhaps the low cost terminals correspondence does not possess ability that continues reception PDSCH data or the like, after the sign of low speed terminal or low cost terminals is received in the base station, implements scheduling of resource according to corresponding transmittability.
Embodiment three
Certain customers' equipment in the long evolving system; Be mainly used in the content that receives or send small data quantity; If this type subscriber equipment adopts the hardware and software that satisfies existing protocol regulation demand, the cost of these subscriber equipmenies can be very high, and the waste of interface-free resources is also very serious.Therefore the subscriber equipment in the present embodiment only possesses the ability that receives small data quantity, concrete be embodied in the data volume that subscriber equipment once can send or receive restriction is arranged, and once can only send or receive the data that maximum is 300 bits such as subscriber equipment.For descending, subscriber equipment detects one's own PDCCH signaling, and the down link control information that carries according to the PDCCH signaling is then known the parameters such as frequency location, modulation and encoding scheme of PDSCH, detects PDSCH.If the data volume that subscriber equipment once can receive has restriction, this restriction need be considered in the base station when distributing the PDSCH resource, avoids transmitting too much data and causes reception to make mistakes.For up; Subscriber equipment need be according to the uplink authorization of indicating among the PDCCH (UL Grant); At the locational Physical Uplink Shared Channel of the time-frequency of correspondence (Physical Uplink Shared Channel; PUSCH) send data, the base station is known under the conditional situation of data volume that subscriber equipment once can send, is only needed to distribute a less Resource Block send data for subscriber equipment.
Subscriber equipment is in the process of access network; Can in RRC connection request or RRC connection foundation completion signaling, report the distributes resource blocks restricted information to the base station, present embodiment is represented the maximum amount of data size that subscriber equipment can send or receive with the distributes resource blocks restricted information in a sub-frame; Perhaps subscriber equipment reports the Resources allocation block message through the UE ability information to the base station after receiving the UE capability requests that send the base station.After said information is received in the base station, be applied to the scheduling to this subscriber equipment, divide resource piece that can be meticulousr is avoided the wasting of resources.Because subscriber equipment can data quantity transmitted have restriction in a sub-frame, subscriber equipment can adopt the low hardware of disposal ability, can reduce the cost of subscriber equipment simultaneously.
Because it is unit with PRB (Physical Resource Block, Physical Resource Block) all that the existing resources piece distributes, the base station can be the one or more PRB of user equipment allocation in a sub-frame.If the maximum amount of data limited size system that subscriber equipment can send or receive in a sub-frame; Then subscriber equipment can report the own PRB number restriction that in a sub-frame, can send or receive to the base station; As in a sub-frame, receiving the resource of 1 PRB, perhaps in a sub-frame, can only send signaling or the data that occupy a PRB resource; Then the PRB that surpasses the restriction number can not be distributed in the base station when this subscriber equipment of scheduling.
Present embodiment also has other implementation; The restricted information of distributes resource blocks can also be that a radio frames is (in the LTE system; A radio frames equals 10 sub-frame; Be 10 milliseconds) the interior subscriber equipment Physical Resource Block number that can receive/send, or the Physical Resource Block number that subscriber equipment can receive/send in the agreement scheduled time.The restricted information of the distributes resource blocks of user equipment to report is received in the base station, needs rational management in view of the above, and Resources allocation under qualifications is avoided the wasting of resources.
Subscriber equipment for the small data quantity transmission; Support 64QAM or 16QAM modulation system can not improve its throughput; Therefore subscriber equipment need not supported 64QAM or 16QAM modulation system (up/descending), or not support MIMO technique (Multiple-Input Multiple-Output; MIMO); RRC connection request that subscriber equipment sends to the base station or RRC connect set up accomplish or the UE ability information in carry and do not support 64QAM or 16QAM modulation system (perhaps carry in the modulation system of support and do not comprise 64QAM or 16QAM), or do not support MIMO technique; After the base station was known, 64QAM modulation technique or 16QAM modulation technique were not adopted to the data that subscriber equipment sends in the base station, did not adopt the MIMO technology in the transfer of data of perhaps carrying out with subscriber equipment.Because subscriber equipment is not supported 64QAM or 16QAM modulation system or MIMO technology, the processing speed of its processor can reduce, and helps the reduction of cost.
In the LTE system, a sub-frame is one millisecond, and comprising two respectively is 0.5 millisecond time slot (Slot), and the base station all comprises the resource of two time slots for the user equipment allocation Resource Block time.The data volume of considering user device transmissions is less; In order to improve the efficient of interface-free resources; Subscriber equipment reports the ability information that oneself possesses the Resource Block that receives single time slot to the base station, after the base station obtains the ability information of subscriber equipment, and can be according to the size of data volume; The meticulousr Resource Block of cutting apart can improve the service efficiency of interface-free resources.Accordingly, the base station need possess the ability according to the time slot allocation Resource Block.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
