Description

The resource allocation methods of multicarrier system and device

Technical field

The present invention relates to the resource allocation techniques field in the mobile communication system, more particularly, relate to the resource allocation methods and the device that are applicable to multicarrier system.

Background technology

Along with the development of mobile communication technology,, introduced High Speed Packet Access (HSPA comprises HSDPA, HSUPA and HSPA+) successively in order to improve traffic peak speed and power system capacity.The HSPA system has adopted key technologies such as high order modulation (for example 16QAM and 64QAM), AMC, HARQ, Node B fast dispatch even MIMO, has greatly promoted the entire throughput of traffic peak speed and sub-district.These key technology emphasis improve shared channel (such as HS-DSCH and the E-DCH) performance of some enhancement mode, cooperate the operation of a series of control channels (such as last/descending channel, HS-SCCH, HS-SICH, E-AGCH and E-HICH of following) simultaneously, make system can insert and dispatch more user simultaneously.

In the existing communication system, normally on a carrier wave of a sub-district, give the user terminal Resources allocation.With TD-SCDMA is example, a subframe comprises TS0-TS6 totally 7 time slots, it is the code channel of 16 (SF=16) that 16 spreading factors are arranged in each descending time slot, up can also have these several spreading factors of SF8, SF4, SF2 and SF1, each ascending time slot is supported 2 physical channels at most, and SF16 and two kinds of spreading factors of SF1 are used in descending permission.

In order further to improve the maximum data rate that the TD-SCDMA terminal can be supported, can adopt multi-carrier mode networking and distributing radio resource, promptly in a sub-district a plurality of carrier waves of support, distribute Radio Resource on a plurality of carrier waves simultaneously to a terminal at every turn.Under the situation of distributing 3 carrier waves, if 5 time slots (TS2 to TS6) of each carrier wave all are set to descending time slot, and all code channel resources in these 5 time slots all are configured to the HS-DSCH channel and distribute to a terminal, then this terminal adopts the about 8.4Mbps of maximum downstream data rate of HSDPA technical support.Multi-transceiver technology combines with the HSPA technology, and the peak rate and the throughput of raising sub-district that can be bigger increase power system capacity.

The multi-transceiver technology though subnetwork equipment has taken the lead in having supported, but for the consideration that realizes difficulty and cost, support that the terminal equipment exploitation of multi-transceiver technology is also relatively backward, have only the high-end terminal equipment of part can design many cover radio frequency paths and support multi-transceiver technology, cost is also higher relatively.What therefore the ability of support multicarrier had nothing in common with each other for terminal, the only support single carrier that has is monitored and transceive data, what have is supported in a plurality of carrier sense common signal channels and control channel, but can only be at single carrier transmitting and receiving service channel, the support uplink single-carrier that has sends descending a plurality of carrier wave and receives business datum simultaneously, supports data transmit-receives up, descending a plurality of carrier waves when also having.

In the prior art, network side is only given the user terminal Resources allocation according to the loading condition of self, can't consider the access capability that user terminal can be supported simultaneously, thereby will exist user terminal not support the incident of described radio-resource-configuration scheme.Such as, described user terminal adopts simplified design, and network side reckons without these particular provisions of user terminal, and distributing radio resource is to described user terminal, be easy to take place described terminal and do not support described radio-resource-configuration scheme, cause consequences such as data transmission fails thus.Therefore the network equipment (such as RNC) must consider that in access procedure the ability of terminal carries out allocation of radio resources, otherwise may cause the reduction of access success rate and the capacity decline of network, directly influences the income of operator.There is not concrete scheme to solve the resource allocation problem of various different access capability terminals in multicarrier system in the disclosed data at present.

Embodiment

Network side will be considered not only whether system has enough resource allocations to give terminal, also will consider the compatibility of terminal, provides the channel configuration that is complementary with terminal capability, and carry out by channel configuration order notice terminal in the allocation of radio resources process.Thereby avoid under the situation of the tenability of not understanding user terminal, carry out radio-resource-configuration and the problem of the terminal access failure that causes.

For the HSDPA/HSUPA/HSPA+ system, resource allocation process is supported its business datum and the part signaling data except the shared channel that will distribute enhancings such as HS-DSCH, E-DCH, also to not admit failure and channel allocation failure if there are enough resource allocation control channel can cause for it distributes a series of control channels (such as last/descending channel, HS-SCCH, HS-SICH, E-AGCH and E-HICH of following) yet.

Concerning 3GPPR4 system and multi-carrier TD-SCDMA system, network side (such as RNC or NodeB) is mainly admitted control and is its distribution service channel when receiving the user to insert request, the access control algorithm is one of wireless resource management algorithm of mobile communication system indispensability, no longer describes in detail as a kind of known technology herein.Among the present invention, as shown in Figure 1, terminal reports its access capability to network after initiating service request, and network side judges whether to admit this request, if can, the access capability allocation of channel resources may that reports according to UE then; Otherwise, refuse this access request.Terminal to network side report the up-downgoing access capability of this terminal, affiliated up-downgoing access capability comprise every subframe terminal up/descending difference can the maximum carrier wave number PU/PD that supports, the maximum up/descending time slot supported of single carrier wave is counted QU/QD and single up/the maximum code channel number RU/RD that supports of descending time slot.

Provide below that a comparatively detailed embodiment describes its access capability of terminal to report and network side reports according to UE or the specific implementation method of these two committed steps of access capability allocation of channel resources may of system default.

The development of 3G system at present, suppose that the physical end ability rating can reduce four kinds:

Type1: terminal only is supported in transceive data on the carrier wave, i.e. the supported maximum carrier wave number restriction of up-downgoing all is 1; And, this carrier wave carries the common signal channels such as pilot channel of sub-district simultaneously, this kind UE does not possess N frequency and multi-carrier capability (in 3-G (Generation Three mobile communication system), in order to reduce interference, improve power system capacity, proposed the notion of N frequency point cell, promptly each cell/section of being covered of Node B distributes a plurality of frequencies, one of them is the dominant frequency point, and other are auxilliary frequency.In a sub-district, has only dominant frequency point configuration common signal channel.At the N frequency point cell, support the user of N frequency point cell can be operated in any one frequency, but and do not require simultaneously and to see the TD-SCDMA industry standard for details in a plurality of frequency transmitting and receiving service data; If terminal can be simultaneously in a plurality of frequency transmitting and receiving service data, then this terminal is the terminal with multi-carrier capability.), UE does not comprise cell " UE Specific Behaviour Information 1 idle " in the RRC Connection Request message in access procedure;

Type2: terminal only is supported in transmitting and receiving service data and control channel on the carrier wave, and be supported in sub-district dominant frequency point and go up common signal channels such as receiving pilot tone, its vocational work carrier wave can not be the main carrier of sub-district, this kind UE possesses N frequency ability, UE is in access procedure, comprise cell " UE Specific Behaviour Information 1 idle " in the RRC Connection Request message, value is " 0000 ", and the supported maximum carrier wave number restriction of its up-downgoing also all is defaulted as 1;

Type3: terminal only is supported in and sends business datum and ascending control channel (such as HS-SICH and E-RUCCH) on the carrier wave, but can on a plurality of carrier waves, receive business datum, common signal channel and control channel simultaneously, its up supported maximum carrier wave number is restricted to 1, and descending supported carrier number maximum constraints is not 1, may be restricted to 3,6 etc. in for example actual the realization, i.e. multicast;

Type4: terminal is supported on a plurality of carrier waves transmitting and receiving service data, control channel and common signal channel simultaneously, and the supported carrier number maximum constraints of its up-downgoing all is not 1, may be restricted to 3,6 etc. in for example actual the realization, i.e. MIMO; The ability of considering network equipment is often greater than terminal, and therefore descending maximum tenability should be more than or equal to up.

Terminal UE reports its access capability to network side, comprise every subframe terminal up/descending difference can the maximum carrier wave number PU/PD that supports, the maximum up/descending time slot supported of single carrier wave is counted QU/QD and single up/the maximum code channel number RU/RD that supports of descending time slot.Network side is judged the grade (promptly belonging to which type) of terminal access capability according to the information of terminal to report, please refer to shown in Figure 2ly, and its concrete judgement flow process is as follows:

Step 1:UE is to the access capability of network side reporting terminal;

Does step 2: network side judge that according to the terminal access capability information of terminal to report or system default the supported maximum carrier wave number of up link is greater than 1?

Be, then the access capability grade of this UE belongs to Type4,

Otherwise, enter step 3: judge that the supported maximum carrier wave number of down link is greater than 1?

Be, then the access capability grade of this UE belongs to Type3,

Otherwise, enter step 4: continue to judge that this UE supports the N frequency?

Be, then the access capability grade of UE belongs to Type2,

Otherwise the access capability grade of this UE belongs to Type1.

According to top four kinds of terminal access capability grades, the present invention has designed following resource allocation methods: with reference to shown in Figure 3, the resource allocation process of UE that belongs to the type1 grade is as follows:

Step 1: network side judges that terminal access capability type is Type1;

Step 2: network side carries out up-downgoing and admits control to judge on main carrier;

Step 3: if could admit this user on main carrier for this user's allocation of channel resources may;

Otherwise enter step 4: refusal inserts

The UE that belongs to the type1 grade only is supported in a monitoring and a transceive data on the carrier wave, i.e. one one receipts.For the control channel of the type terminal distribution and Traffic Channel must and the beacon channel (such as P-CCPCH) of sub-district and common signal channel (such as RACH, FACH, PCH) on same carrier wave, hereinafter arrange the main carrier that this carrier wave is the sub-district, otherwise might cause not network enabled end channel appointed configuration and can't proper communication of UE; In case after RNC admits control to this class user, if can admit this user, then be its channel resource that distributes main carrier, the user will use the Radio Resource of this carrier wave to communicate, up to leaving this sub-district or out-of-service always.The final channel that distributes for this user on main carrier can not surpass the access capability restriction of UE, specifically comprise the maximum up/descending time slot supported of single carrier wave count QU/QD and single up/the code channel number RU/RD of the maximum support of descending time slot.

At this moment, the access control algorithm need consider whether time slot, spreading code and power resource in the main carrier can provide factors such as required Traffic Channel of this service communication and control channel resource.

With reference to shown in Figure 4, the admittance control deterministic process of UE that belongs to the type2 grade is as follows:

Step 1: network side judges that terminal access capability type belongs to Type2;

Step 2: network side carries out up-admission control on single carrier judges, judges whether to admit this user;

Cannot admit this user, then enter step 3 ';

Step 3 ': judge whether other carrier waves in addition? be, then return step 2, otherwise refusal inserts;

Can admit this user, then enter step 3;

Step 3: network side carries out descending acceptance control on this carrier wave judges, judges whether to admit this user;

Cannot admit this user, then enter step 3 ';

Can admit this user, then enter step 4;

Step 4: on this carrier wave, distribute the up-downgoing channel resource for the user.

The UE that belongs to the type2 grade only is supported in transmitting and receiving service data and control channel on the carrier wave, and this carrier wave can be also can not be the dominant frequency point of sub-district.

For dedicated channel, shared channel and the control channel thereof of the type terminal distribution must be configured on the same carrier wave, otherwise might cause not network enabled end channel appointed configuration and can't proper communication of UE, this carrier wave can be, also can not be on the main carrier of this sub-district; Terminal by main carrier make a call the request after, network side is admitted control successively to this class user in each carrier wave, if can admit this user by certain carrier wave, the channel resource that then distributes this carrier wave for it, if network determines to use HSPA to be this user's service, then be assigned in the formation of this carrier wave and wait scheduling, and be that it distributes control channel on this carrier wave.The final channel that distributes for this user on this carrier wave can not surpass the access capability restriction of UE, specifically comprise the maximum up/descending time slot supported of single carrier wave count QU/QD and single up/the code channel number RU/RD of the maximum support of descending time slot.

At this moment, the access control algorithm need consider whether time slot, spreading code and power resource in assignable certain carrier wave can provide required Traffic Channel of this service communication and control channel resource.

As a kind of better embodiment, insert and Resources allocation the time for Type2 user, pay the utmost attention to up, promptly distributed suitable up channel earlier after, corresponding allocation of downlink channel on same carrier wave,

The type terminal also can be worked on the different carrier of same sub-district, specifically can realize by the channel reconfigure command that RNC issues.

With reference to shown in Figure 5, the admittance control deterministic process of UE that belongs to the type3 grade is as follows:

Step 1: network side judges that terminal type is Type3;

Step 2: network side carries out up-admission control on single carrier judges, judge whether to admit this user?

Cannot admit this user, then enter step 2 ';

Step 2 ': judge whether other carrier waves in addition? be then to return step 2, otherwise refusal insert.

Can admit this user, then enter step 3;

Step 3: on this carrier wave, distribute uplink channel resources for the user;

Step 4: network side continues to carry out descending acceptance control on this carrier wave judges, judges whether to admit this user;

Cannot admit this user, then enter step 4 ';

Step 4 ': judge whether other carrier waves in addition? be, then return step 4, otherwise refusal inserts;

Can admit this user, then enter step 5;

Step 5: network side is user's allocation of downlink channel resource on this carrier wave;

Step 6: judge whether the descending number of distributing carrier wave reaches the maximum of terminal capability restriction;

If do not reach, then enter step 6 '; Having reached then, resource allocation process finishes;

Step 6 ': judge whether to also have other carrier waves to exist?

Be then to return step 4, otherwise resource allocation process finish.

The terminal of type3 type only is supported on the carrier wave and sends business datum, but can receive business datum on a plurality of carrier waves, comprises monitoring common signal channel and control channel, i.e. multicast.For the downlink dedicated channels of the type terminal distribution, DSCH Downlink Shared Channel and corresponding control channel thereof can be configured on a plurality of carrier waves, and special uplink channel, Uplink Shared Channel and corresponding control channel thereof can only be configured on the carrier wave, and this carrier wave can be, also can not be on the main carrier of this sub-district; Terminal by the main carrier request of making a call after, RNC admits control to this class user, if can admit this user, then for it disposes corresponding channel resources respectively.

At this moment, the access control algorithm need consider whether time slot, spreading code and power resource in assignable one or more carrier wave can provide required Traffic Channel of this service communication and control channel resource.

In the time of for Type3 user's access and Resources allocation, pay the utmost attention to up, after promptly having distributed the up channel that is fit to earlier, corresponding allocation of downlink channel on same carrier wave, then on other carrier waves, continue the allocation of downlink channel, final descending carrier number of distributing can not surpass the access capability restriction of UE, and for the channel that this user distributes can not be above the access capability restriction of UE, specifically comprise every subframe terminal up/descending difference can the maximum carrier wave number PU/PD that supports, the maximum up/descending time slot supported of the single carrier wave of each subframe count QU/QD and single up/the maximum code channel number RU/RD that supports of descending time slot.

If descending shared channel and the control channel resource that has disposed a plurality of carrier waves simultaneously, then the type terminal can be worked on the different carrier of same sub-district in timesharing, concrete scheduling by the base station realizes, such as the time period that can work on its corresponding shared channel at notice UE on the different control channels.

Consider the control complexity and the control precision of the implementation complexity and the network of terminal, preferred embodiment is that down control channel and ascending control channel are distributed on the same carrier wave.

Consider the load balancing problem of intercarrier, preferred embodiment is a network side when distributing control channel, chooses carrier wave successively to the order of weight on the lenient side according to load.

The terminal that belongs to the type4 type is supported in while transmitting and receiving service data, i.e. MIMO on a plurality of carrier waves.For the channel of the type terminal distribution can be distributed on a plurality of carrier waves, when this Terminal Type inserted, RNC is queuing or Resources allocation on a plurality of carrier waves of its support simultaneously.Therefore when admitting control, only need to consider it is that whether remaining carrier wave, time slot, spreading code and power resource can provide required Traffic Channel of this service communication and control channel resource in this sub-district.The final channel configuration that distributes all can not surpass the access capability restriction of UE, specifically comprise every subframe terminal up/descending difference can the maximum carrier wave number PU/PD that supports, the maximum up/descending time slot supported of the single carrier wave of each subframe count QU/QD and single up/the maximum code channel number RU/RD that supports of descending time slot.In general, can be up according to the every subframe terminal in the user's access capability restriction/descendingly can decide which direction of preferential access by the maximum carrier wave number PU/PD that supports respectively, then go up row major such as PU less than PD and select the allocation of carriers channel, corresponding allocation of downlink channel on this carrier wave then, if the descending ability of terminal can also insert more carrier wave, then on other carrier waves, continue the allocation of downlink channel, final descending carrier number of distributing can not surpass the access capability restriction of UE, the benefit of doing like this is to reduce the carrier wave number that the user receives and dispatches simultaneously, improve up and down power, the accuracy of Synchronization Control reduces the complexity of terminal traffic gimmick and measurement control etc.; If there have part upstream or downstream carrier wave to take place in the network to be congested, deciding then according to the not congested carrier wave number of up-downgoing, if descending not congested carrier wave number is less than up not congested carrier wave number, then descend row major to select the allocation of carriers channel, then the corresponding up channel that distributes on this carrier wave.

Receiving element, the service request of initiating in order to receiving terminal, and obtain the access capability information of terminal;

Terminal access capability grade judging unit, in order to judge the access capability grade of terminal according to the access capability information of terminal to report or system default, described access capability information comprises the supported maximum carrier wave number of Uplink/Downlink and whether can support the N frequency.

Allocation units, when the admission judgment unit judges can be admitted the service request of terminal, allocation units distributed the channel resource that is complementary according to the terminal access capability grade that receiving element obtains;

The present invention takes into full account the compatibility of network to all kinds terminal, when solving that network side is given the user terminal Resources allocation in the prior art, exist user terminal not support the incident of described radio-resource-configuration scheme to take place, cause follow-up consequences such as access failure thus.The resource allocation methods and the device that adopt the present invention to propose can reduce the percent of call lost, improve network quality and the income of operator.
