Embodiment
Describe various embodiment now with reference to graphic, in each is graphic, use identical Ref. No. to refer to components identical from start to finish.Hereinafter, for ease of explaining, a large amount of details have been set forth, so that well understanding one or more embodiment is provided.Yet, apparent, can not have to put into practice described embodiment under the situation of these details.In other example, show well-known construction and device with the form of calcspar, so that set forth one or more embodiment.
Used term " assembly ", " system " and similar terms are intended to represent the entity relevant with computer in the application's case, and it both can be the combination, software of hardware, hardware and software, also executory software.For example, assembly (but being not limited to) process, processor, object, executable file, execution thread, program and/or computer of on processor, moving.One or more assemblies can reside in process and/or the execution thread, and assembly can be positioned on the computer and/or is distributed between two or more computers.Equally, these assemblies can be carried out from the various computer-readable medias that it stores various data structures.Described assembly can communicate by this locality and/or remote process, for example, according to the signal with one or more packets communicate (for example, from one with local system, distributed system in another component interaction effect and/or the data of the assembly by signal spans network (for example internet) and other system interaction effect).
In addition, in conjunction with subscriber stations various embodiment are described in this article.Subscriber stations also can be called system, subscriber unit, travelling carriage, mobile device, remote station, access point, base station, remote testing, access terminal machine, user terminal, user agent or subscriber equipment.Subscriber stations can be cellular phone, cordless telephone, session initiation protocol (SIP) phone, wireless local loop (WLL) platform, PDA(Personal Digital Assistant), the handheld apparatus with wireless connections ability or other processing unit that is connected to radio modem.
In addition, can use standard programming and/or engineering design technology is a kind of method, equipment or goods with various aspects as herein described or feature construction.Term used herein " goods " is intended to include can be from the computer program of arbitrary computer readable device, carrier or medium access.For example, computer-readable media can be including (but not limited to) magnetic storage device (for example, hard disc, floppy disc, magnetic stripe ...), CD (for example, CD (CD), digital versatile disc (DVD) ...), smart card, and flash memory device (for example card, rod, key drive).
Referring now to graphic, N system resource blocks 100 of Fig. 1 graphic extension one group is so that understand the method that wherein can operate various embodiment that this paper provides.These resource block 100 can be (for example) time slot, frequency, code slots, previous every combination etc.The general remark of one this type of block of son group is (for example) block index list, and for example, specific user's block tabulation is given in assignment.For example, such as 2,3,10,11,12, the index list of 13} can be used to expression and gives this type of block of user's assignment.Another selection is, can use boolean's array to describe same assignment, for example, and the array { 01100000011110} of N position.Adopt the legacy system of this type of assignment mechanisms will realize remarkable expense in doing so, even have different characteristics.For example, about transmitting the required bit quantity of this type of assignment, block index list can be roughly more expensive along with the growth of wanting assignment subset of blocks size.On the other hand, no matter boolean's array is showed fixing a little expense and 1 and 0 quantity, but described expense is big relatively, particularly along with the growth of N.
In addition, therein assignment is restricted under the situation of the block of contiguous sets or resource, can comes this type of assignment of signalling by indicating first block and the block total quantity in the described assignment in the described assignment.For example, such as but 11,12,13,14, the block index assignment signal of 15} turn to 11,5}, wherein set user's first block is given in " 11 " assignment of indicating, and " 5 " indicate total quantity of the block that continues (wherein 11 is first block) of assignment.Still in addition, if the ordering of known users then can not have to transmit assignment signal under the situation of user profile.For example, as long as all users know the assignment at all other users, then only need the number of blocks of signalling with assignment.For example, if with user 1:1-5}, user 2:6-7} and user 3:8-12} represents the assignment at user 1-3, and if all users know its relative users quantity, then this assignment can be written as 5,2,5}.Yet this assignment needs in the system all with the assignment of knowing per family to all other users, and for example, unless this is because user 2 knows the block 1-5 that given user's 1 assignment, otherwise it may not know that its assignment is with block 6 beginnings.Therefore, the system that can see the method that make up to adopt this type of conventional assignment system resource can be costliness and can increase the burden of the system transmissions resource that wherein makes up described system in fact.Be convenient to overcome this type of conventional burdens as seeing system and method as herein described.
Fig. 2 is the diagram of channel table 200, and described channel table can be used for the wireless network connected system so that allocation system resource (for example, transmission channel, time slot, code slots, frequency ...), and it comprises a plurality of users (for example, device) and corresponding resource assignation thereof.This table 200 can be known that described user can use the channel table index to come interpret assignment messages by all users.For example, according to table 200, can write such as the user 1: the assignment of index 2}, compare with block index and/or boolean's array technique, this can reduce the assignment signal expense.Following table is set forth the general introduction to conventional assignment mechanism characteristic and associated benefits and result.
| Method | Restricted | Expense | All users must watch all assignments |
| Block index list | Not | High | Not |
| Block continues | Be | In | Not |
| Boolean's array | Not | High | Not |
| Known user's order | Be | Low | Be |
| Channel table | Be | In | Not |
Therefore, can see that typical assignment allocative decision does not provide not only cheap but also non-limiting and do not need all users in the system to come observation post that the mechanism of user's assignment is arranged.
Fig. 3 graphic extension can be distributed to group's resource block 300 of a plurality of users.This type of resource for example can comprise, system channel, time slot, frequency, code slots and analog.According to embodiment, sticky assignments (for example, the assignment of continuously effective till receiving other assignment signal) can be used to the system resource in assignment (for example) cordless communication network (for example, OFDM, OFDMA, CDMA, TDMA, GSM...).This type of assignment also can be restrictive, so that the ability of the resource block group being carried out any assignment with restriction is that cost reduces signal expense.Make the distributing signal cost minimization simultaneously for overcoming this type of restriction, can use supplemental assignments to come management of system resource and satisfy the user resources needs.For example, resource block 300 can comprise the first block group 302, and the described first block group contains the block 1-4 that wants assignment to give user 1.Comprise the second block group 304 of block 5 and 6 can for user's 2 assignments.At last, block 7-9 can comprise by the block group 306 of not using block to form.The requirement that can determine user 1 has been increased to the point that user 1 needs additional resource blocks.According to this aspect, can produce supplemental assignments, its extendible user's 1 current assignment but not replace current assignment fully.For example, thus can incorporate in the supplemental assignments and it can be recognized as supplemental assignments indicating the position described assignment is labeled as supplemental assignments recipient device.If the identifier position is set at " replenishing ", then can will add the assignment that described user had before had to by the channel or the resource of described message semantic definition.If the identifier position is not set at " replenishing ", then can be with described message interpretation for replacing previous assignment.Be understood by those skilled in the art that, can adopt other message marker method about the supplemental/non-supplemental assignment, and embodiment described herein is not limited to adopt the identifier position, but can use any suitable sign mechanism, no matter be implicit expression or explicit.
For example, user 1 initial viscosity assignment can be expressed as 1,2,3,4:0}, wherein " 0 " indication non-supplemental assignments and channel 1-4 is the channel that is assigned.In addition, for therein allocated channel be to alleviate the signal transmission cost under the situation about continuing, this non-supplemental assignments can be expressed as [1,4:0] first integer " 1 " expression first allocated channel wherein, and second integer " 4 " is represented the length of allocated channel.For example, if will give user 1 with supplemental channel assignment, then can produce supplemental assignments and it is transferred to user 1 because of the user who increases needs and analogue.For example, 7,8, the 9:1} assignment extraly of can indicating gives user 1 channel 7,8 and 9.In this example, the identifier position is set at " 1 " and replenishes and should only not replace previous user 1 assignment of channel 1-4 but expand this assignment to indicate described being assigned as.In addition, because extra channel 7-9 continues, so supplemental assignments can be expressed as [7,3:1], and wherein 7 is first supplemental channel assignment, is 3 and want the length of the contiguous supplemental channels of assignment.According to this back on the one hand, when with conventional system (for example, must transmission for example 1,2,3,4,7,8, the huge secondary signal of 9:0}) when comparing, assignment signal overhead can further reduce.
In others, supplemental assignments can be used as decremental assignments, a kind ofly reduces the assignment of assigned resources.This can finish by the transmission assignment, wherein replenishes flag through setting but only discern one or more existing resources that the user is given in assignment.In this way, the user will receive supplemental assignments, and reduce its resource.This method allows to use same format messages to implement to increase and reduce the supplemental assignments of resource allocation.Can save the expense of new assignment like this, not need the user to carry out implicit solution simultaneously and remove the assignment processing.
For example, the user receive and can be expressed as 1,2,3, the initial viscosity assignment of 4:0}, wherein " 0 " non-supplemental assignments of indication and channel 1-4 is the channel that is assigned.Then, user 1 receives supplemental assignments, and for example, { 3:1} can represent that channel 3 and 4 is kept because of being assigned to user 1, and other channel 1 and 2 will be removed from user 1.In this example, the identifier position is set at " 1 " to indicate described previous user 1 assignment that replenishes and should only not replace channel 1-4 that is assigned as.Another is chosen as, and { 3:1} can represent and will remove channel 4 for user 1 keeps channel 1-3 supplemental assignments.
According to the parties concerned, can be according to the affirmation of the previous assignment of user (is for example predicted the supplemental assignment transmission authority, receive some and confirm data, for example, the affirmation that successfully receives or decode on the checking message of successful grouping or sequential decoding, the forward link on the indication reverse link ...).By this way, network can be confirmed user's assignment before replenishing this assignment.
Fig. 4 is a series of non-diagram of carrying out in time that continues (for example, non-sticky) assignment.Among the figure frequency diagram is illustrated as type of system resource, although but the system resource of assignment is not limited to frequency with assignment.According to described figure, the place gives the first user U1 assigned frequency A in the time 1.At times 2 place, can with frequency A heavily assignment give user 2, this part ground is because initial assignment is not a sticky assignments.Among the figure frequency C is illustrated as will time 1 and time 2 during both assignment give user 3.Yet giving user 3 frequency C assignment is not sticky assignments, thus user 3 frequency C keep can be in the independent assignment at each place of time 1 and time 2, thereby the assignment signal overhead that causes not expecting increases, and this can influence system resource nocuously.Therefore, adopt the system of non-sticky assignments will need every time frame n different assignment message to give n usable frequency of N user's assignment.
Fig. 5 is the diagram of a series of lasting or " viscosity " assignments 500 of carrying out in time, for example, can use described assignment at various embodiment as herein described.For example, can first group of assignment be transferred to user 1-N, and these assignments are sustainable till transmitting one or more subsequent assignment for one or more individual users first o'clock image duration.Therefore, first group a N assignment can be enough to provide the system resource assignment up to expectation and/or need till these assignments change (for example, because of the user needs, bandwidth ...) to all users.If as becoming available, then this frequency assignment can be given subsequent user such as U6 at the frequency D of t3 place graphic extension.By this way, compare with adopting non-sticky assignments, need be at the less assignment message of transmission over networks.
In addition, if the user needs extra resource, then can give arbitrary user 1-N with the free system resources assignment.For example, can determine except that frequency E that U5 certain time during network communication also need to locate the extra frequency availability.Given U5 assigned frequency E and F with indication the subsequent assignment transmission of messages can for U5.In addition, in conjunction with the various embodiment that this paper describes in detail, this extra assignment message can be the consumption of supplemental assignments to alleviate Internet resources when weighing assigned frequency to U5.
In addition, supplemental assignments can be used as decremental assignments.For example, about U5, after being assigned frequency E and F, it can determine to remove resource sometimes.So, supplemental assignments identification frequency F.U5 is that frequency E is removed assignment with this message interpretation, and will stop utilization or expect communicating on frequency E.
Fig. 6 is the diagram of system 600, and described system supplemental assignments easy to use is so that to come distributing system resource by reducing the mode that signal magnitude reduces overhead and/or transmission requirement.System 600 can comprise the assignment component 602 that control system resource (for example, channel, frequency, time slot, code slots ...) is distributed.Assignment component 602 comprises sticky component 604, and its generation can continue the sticky assignments till user's (for example, device) receives subsequent assignment information in time.Assignment component 602 comprises supplemental component 606 in addition, its produce supplemental assignments with when the user need change according to user's needs dispatching system resource of described change.In addition, supplemental component 606 can be used for removing assignment for the resource of one or more user's sets 610 assignment.For example, supplemental assignments can be discerned a resource, thereby can infer that from a described resource other has removed the resource of assignment according to pre-defined algorithm, or identification resource that keep or that removed assignment clearly.
According to example, can give user's set 610 initial assignment one son group available resources, for example, 1,3,4,6:0}.User's set 610 can need extra resource subsequently and can determine resource block or channel 2 is available.According to embodiment, can produce supplemental assignments [2,1:1] and it is transferred to the user to add with block 2 beginnings and to have the resource (for example, channel 2) of length 1.By this way, system 600 does not need to retransmit defeated huge complete assignment message (for example, { 1,2,3,4,6:0}).
According to another example, can come to user's assigned resources 1-4 by assignment (for example, using block index array, contiguous assignments ...) or similar assignment by assignment component 602 such as [1,4:0].After user resource request increases, can give user's assignment extra resource by supplemental assignment message.Conventional method may be brought up again and be handed over complete new assignment message (for example, [1,5:0]) resource block 5 is added to described user's the tabulation of assign resources.Another is chosen as, and can produce supplemental assignments by supplemental component, for example, and [5,1:1].Yet resource block 5 must can be used for using the legacy system at the message format of the minimizing of resource 1-5 contiguous assignments, as using thick bracket (for example, " [] ") represented herein.Just in case resource block 5 suffers the sticky assignments (for example, unavailable) to another user, even resource does not continue, system 600 also can permit becoming the original supplemental assignments of implementing resource with reduced overhead.Therefore, if non-continue resource is available, then legacy system will need to produce expensive new assignment message (for example, { 1,2,3,4,6:0}) and it will be transferred to the user with assigned resources 1,2,3,4 and 6.On the contrary, supplemental component 606 can produce the supplemental assignment message such as [6,1:1], and its indication will be by expanding user's assigned resources with resource 6 beginnings and resource allocation with vector length 1.Then, can supplemental resource assignment be transferred to user's set 610 via one or more base stations 608.
According to another example, the user who is in the communication event starting stage can need a large amount of system resource blocks.For example, can determine that block 3,4,7 and 8 can use for assignment component 602.In this case, can produce and/or transmit two simple message simultaneously to give the user with channel assignment.For example, described message can be expressed as [3,2:0] and [7,2:1].Therefore, sticky component 604 can produce initial assignment message and supplemental component 606 can produce supplemental assignments, thereby can be transferred to the user simultaneously so that the 600 one-tenth original non-channels 3,4,7 and 8 that continue of user's assignment of giving of system to reduce.To understand, can use herein system and/or method in conjunction with the system that adopts non-sticky assignments and sticky assignments according to various embodiment described in detail.
Fig. 7 graphic extension is convenient to supplemental resource assignment is provided to the system 700 of user to reduce the assignment signal overhead cost of communication network.System 700 comprises and can be the assignment component 702 that the user produces resource assignation.Assignment component 702 comprises and can be the sticky component 704 that the user produces viscosity (for example, continue) assignment selectively, wherein keeps this type of assignment till follow-up non-supplemental assignments signal is reseted user's resource assignation.If expectation, then assignment component 702 can produce non-sticky assignments, and uses non-sticky assignments can be convenient to reduce overhead by the quantity that alleviates to the required assignment message of network user's Resources allocation.In case assignment component 702 and/or sticky component 704 are given the network user with the assignment assignment, supplemental component 706 can optionally produce supplemental assignments and distribute extra resource to give one or more users.In addition, supplemental component 706 can be used for removing assignment for the resource of one or more user's sets 710 assignment.For example, supplemental assignments can be discerned a resource, thereby can infer that from a described resource other has removed the resource of assignment according to pre-defined algorithm, or identification resource that keep or that removed assignment clearly.
Fig. 8 is the diagram of system 800, and described system is convenient to produce supplemental assignments and alleviates the resource allocation cost simultaneously with user's allocation system resource of giving communication network.System 800 comprises assignment component 802, and it produces resource assignation so that be transferred to one or more network user's devices 810 by one or more base stations 808.This type of assignment can be non-sticky (for example, at each time produce image duration).Assignment component is included as device 810 and produces the sticky component 804 of non-additional viscosity or lasting assignment, and wherein the device 810 at the user continues this type of resource assignation up to transmit follow-up non-supplemental assignment message to the specific user till.By transmitting continuous assignment, sticky component 804 can be convenient to reduce to send to the network user's number of assignment messages.For further reducing transmission cost and assignment message size, assignment component 802 can comprise the supplemental component 806 of generation about previous graphic described supplemental assignment message.In addition, supplemental component 606 can be used for removing assignment for the resource of one or more user's sets 610 assignment.For example, supplemental assignments can be discerned a resource, thereby can infer that from a described resource other has removed the resource of assignment according to pre-defined algorithm, or identification resource that keep or that removed assignment clearly.
This type of supplemental assignment message can comprise the identifier position, and its notice receiving system 810 described message are actually additional and existing resource assignment that answer expanding device 810 but not replace this type of existing assignment.For example, the identifier position can be attached to assignment message by assignment component 802 so that wherein the value of identifier position can to indicate described assignment message for the message of " 0 " be the sticky assignments of standard, thereby included assignment should be replaced existing assignment thus.In addition, if the identifier position has value " 1 ", then this can to indicate assignment message be that supplemental assignment message and assignment wherein should be added to the existing resource assignment.As be understood by those skilled in the art that, can be according to the needs of system design goal and similar target, be designed to provide the effectively low indication of supplemental/non-supplemental state with the identifier position, identifier position " 1 " (for example, height) can be indicated non-additional state and null value can be indicated additional state whereby.
Fig. 9 graphic extension is convenient to give with the minimal-overhead cost system 900 of user's allocation system resource.System 900 comprises assignment component 902, and it can give one or more user's set 910 assigned resources via one or more base stations 908 in communication network, for example, and frequency, channel, transmission time slot etc.Assignment component 904 can comprise sticky component that non-supplemental assignments is provided and the supplemental component 906 that can produce supplemental assignments, as this paper about previous graphic as described in.Assignment component 902 is operatively coupled to each in memory 912, processor 914 and the AI assembly 916 in addition, and in memory 912, processor 914 and the AI assembly 916 each is coupled to each other with mode of operation.In addition, supplemental component 906 can be used for removing assignment for the resource of one or more user's sets 910 assignment.For example, supplemental assignments can be discerned a resource, thereby can infer that from a described resource other has removed the resource of assignment according to pre-defined algorithm, or identification resource that keep or that removed assignment clearly.。
With reference to Figure 10-12, its graphic extension and the relevant method of generation replenishment system resource assignation.For example, each method can be relevant with the supplemental assignments in OFDM environment, OFDMA environment, CDMA environment or any other suitable wireless environment.Although for the purpose of simplifying explanation, described method shown and be described as a series of actions, yet should be appreciated that and know, described method is not limited to running order, this is because according to one or more embodiment, and some action can be by being different from that the illustrated and described order of this paper carries out and/or carrying out simultaneously with other action.For example, be understood by those skilled in the art that and know, relevant state or incident that a kind of method alternately is expressed as is a series of (for example, in the state diagram).In addition, be not need whole shown in action make up method according to one or more embodiment.
Separately with reference to Figure 10, method 1000 is used to produce the replenishment system resource assignation and it is provided to the user of wireless network now.Method 1000 can permit using the efficient channel assignment techniques to avoid major limitation to this type of technology simultaneously.Although utilized supplemental resource assignment, network can make user's resource assignation and user's needs closely mate and make the use that network can the optimization system resource, even but assigned resources group is assigned message format limits.In addition, increase or reduce the resource of assignment by using supplemental assignment message, method 1000 can reduce to transmit to reach the quantity of required assignment of desired resource allocation and releasing assignment message.
For ease of utilizing supplemental resource assignment,, can produce initial resource assignment and it is transferred to one or more users' device via network at 1002 places.For example, assignment is to the non-supplemental assignments of resource (for example, network, channel, time slot etc.).In addition, this type of assignment can be sticky assignments so that make in time and will minimize in the assignment total quantity of transmission over networks.In case assignment has been transferred to the user of network, whether with definite Any user need extra resource, or should not reduce resource if then can monitor described network at 1004 places.Definite user also needs resource assignation except that described user's existing assignment after, can be that described user produces supplemental assignments and it is transferred to described user's communications device at 1006 places.In case transmitted supplemental assignments, then described method can turn back to 1004 so that whether continuation monitoring and/or definite Any user need extra resource, or do not tackle existing resource and remove assignment, thereby can trigger the generation and the transmission of further supplemental resource assignment subsequently at 1006 places.
For example, can give user's initial assignment resource block 1-5 at 1002 places.If the user needs extra resource, then 1004 places determine can detect this requirement, and sentence the mode of being convenient to reduce about the overhead of assignment message size etc. 1006 and produce these resource assignations.For example, the generation of supplemental assignments can comprise that at first definite which resource (and/or resource block) is available.According to this assessment, can produce supplemental assignments and add that to it flag is identified as described assignment additional to permit network and/or receiving system.For example, if determine that resource block 11 and 12 can be used for assignment and gives the user, then can produce the supplemental messages of assignment block 11 only and 12 at 1106 places.Described message suitably can be labeled as " replenishing " to guarantee to add block 11 and 12 to assignment block 1-5 but not replace these blocks.Under the situation of decremental assignments, determine that 1004 can detect the needs that reduce resource and transmit these resources in 1006 forms of sentencing supplemental assignments subsequently and remove assignment.
Can be convenient to the mark assignment message by following operation: the identifier position is appended to all assignment messages (no matter its be what to replenish also be non-additional), maybe should expand existing assignment so that the value of identifier position notifies recipient's device and/or the described assignment of network should replace existing assignment.For example, the identifier position with value " 0 " can indicate that the assignment as non-additional, can indicate that the assignment as additional and be worth " 1 ".To understand, the value of identifier position can be reversed, if this type of value be used for consistently representing two of assignment message may states each (for example, replenish and non-additional).In addition, assignment is that to replenish also be that non-additional sign is not limited to service marking symbol position, but can use any suitable designator (for example, flag in bit sequence, message prefix, the message header ...) realize.
Forward Figure 11 now to, its graphic extension is used for producing and transmitting to the user at wireless network environment the method 1100 of supplemental assignments.At 1102 places, can transmit initial resource allocation to the network user.For example, can produce non-supplemental assignment message and it is transferred to individual user devices, and not need to know assignment to other device.At 1104 places, mobile device can offer confirmation signal network to verify the successful decoding and the acceptance of assigned resources message.At 1106 places, can make about one or more mobile devices and whether need additional system resources or should be from the user resource do not removed determining of assignment.If do not need to determine extra resource, maybe should remove assignment, then described method can stop.
If at 1106 places, determine that device needs extra resource, maybe should remove assignment, then provide these resources at the available supplemental assignments in 1108 places.For example, the mobile device such as cellular phone can receive the initial resource allocation of permitting transfer voice at 1102 places.Can indicate the user of mobile device just attempting to download webpage the definite of 1106 places, transmission of digital photo or video clipping etc., and this may need extra transmission bandwidth.Therefore, at 1108 places, can produce supplemental resource assignment satisfying described device, and the supplemental resource assignment that is produced can be transferred to described device to satisfy the device needs to the bandwidth needs.
According to related example, if the device initial authentication is to reception and/or acceptance and four the extra resource block of needs of resource block 100-104, then can be (for example with supplemental assignment message, [X, 4:1] is transferred to described device, and wherein X is the integer of first resource block in the available resources block of expression first contiguous sets.Owing to confirmed all previous resource assignations at 1104 places, known that therefore the supplemental assignments that is used for 1108 places produces and the complete list of available resources of transmission.After the supplemental assignment transmission at 1108 places, described method can turn back to 1104 so that carry out another repetition of assignment verification, and this can be included in monitor network with determine at 1106 places subsequent supplemental assignments to one or more users whether be must before, the checking supplemental assignments.To understand, supplemental resource assignment message does not need to comprise the continue resource assignment, but this type of assignment can be so that generation makes things convenient for and the mode (for example, block index array ...) of the cost-efficient assignment message of tool is expressed.For example, this type of assignment is expressed in available two index and an identifier position.
Referring now to Figure 12, method 1200 is used for supplemental resource assignment is offered communicating devices on wireless network.At 1202 places, can carry out initial resource allocation and assignment can be transferred to one or more devices that use described network.For example, can be (for example by non-additional sticky assignments, 1,2,3,6,7,10:0} comes to first user's assigned resources block, simultaneously (for example according to the second non-supplemental assignment message, 4,5,8:0}) come to second user's assigned resources block, wherein " 0 " expression assignment message is identified as non-additional identifier position.The user does not need to know (for example, not needing to observe) other user's assignment message.At 1204 places, can confirm assignment message by recipient's mobile device.For example, simple acknowledge message can be transferred to network to verify to the reception of assignment message, successfully decoding and/or acceptance.By this way, network can learn accurately which resource still can be used for supplemental assignments etc.At 1206 places, can make about which (if any) device and need additional system resources maybe should remove determining of resource.If do not need extra resource maybe will remove needs, then described method can stop.If one or more devices need extra resource maybe will remove needs, then described message can proceed to 1208.For example, above-mentioned first user can need three extra resource block to be used for the operation on network.Can be at the 1208 places the most effective supplemental messages form of deduction so that with minimum expense cost (for example, based on cost effectiveness analysis, Techniques of Optimum ...) come to provide supplemental assignments to first user.
For example, if confirmed all initial resource block assignments according to 1204, know that then next three available resources block is a block 7,9 and 11.The supplemental assignment message that comprises these block assignments can be expressed as 7,9,11:1} and can be transferred to first user at 1210 places.Yet more efficient message (for example, shorter message) can be [9,4:1], and it can transmit the supplemental resource assignment with four continue resource blocks of block 9 beginnings.Because block 10 has been assigned the device to first user, therefore there is not conflict, and can gives first user to satisfy user's resource needs new block 9,11 and 12 assignments in addition.Can make (for example, using artificial intelligence technology, machine learning techniques ...) at 1208 places and can be convenient to and determine that described more effective (for example, more cheap) message is desired deduction, and can select this deduction to be used for the generation and the transmission at 1210 places.Under the situation of decremental assignments, determine that 12064 can detect the needs that reduce resource and transmit these resources in 1208 forms of sentencing supplemental assignments subsequently and remove assignment.
According to similar example, can determine that second user can't verify the reception/acceptance to its initial assignment message at 1204 places.As long as this type of resource block still available (for example, as yet not assignment give the 3rd or subsequent user device), then can such as 4,5, give first user with described resource block assignments in the supplemental assignment message of 8:1}.Only first user need know supplemental assignments, because supplemental assignments is transparent to all users except that the recipient, further to reduce network overhead, processing time etc. again.In addition, at 1208 places, deducibility can be reduced to supplemental assignment message the contiguous assignments such as [4,5:1], " 4 " expression first resource block wherein, and " 5 " expression is with a series of blocks that continue of 4 beginnings, and that " 1 " is denoted as message is additional.This situation is permitted because know block 6 and 7 assignment give first user, thereby more effective supplemental assignments that continues can not clashed with first user's existing assignment.By this way, the deduction of making at 1208 places can be convenient at 1210 places the generation and the transmission of supplemental assignment message, and described supplemental assignment message requires about expense and/or assignment message transfer size is that tool is cost-efficient.
Figure 13 shows exemplary wireless communication system 1300.For simplicity's sake, wireless communication system 1300 is described a base station and a terminating machine.Yet, should be appreciated that described system can comprise more than a base station and/or more than a terminating machine, wherein extra base station and/or terminating machine can be similar to or be different from example base station and terminating machine hereinafter described substantially.In addition, should be appreciated that base station and/or terminating machine can use system as herein described (Fig. 6-9) and/or method (Fig. 9-12) to be convenient to reach radio communication therebetween.
