Description
Technical field
The present invention relates to the methods of channel resource allocation, more particularly, to the superposition authorized party of the semi-static transmission of narrowband systems
Method.
Background technique
The design of cordless communication network is limited to available band situation, is for distributed continuous and a wide range of bandwidth
System, all kinds of control channels of design and Traffic Channel that can be more calm.But it is discrete for available band and each is discrete
How the relatively narrow band resource of available band reasonably designs all kinds of channels, and how adequately to utilize discrete narrow band resource
It can be more difficult than broadband system.Furthermore, it is contemplated that the considerations of cost problem of terminal and system design in actual product,
Monitoring and reception that control channel, especially authorization channel are carried out in narrow bandwidth range are only supported there may be great amount of terminals.For
Control channel needs to be weighed between efficiency of transmission and transmission quality to guarantee high reliability, it is especially this from
The system of narrowband is dissipated, the bit number of the single transmission of single frequency point is less.If that needing once to transmit more authorization letter
Breath is just likely to be limited to the bit number that the authorization channel of single transmission is carried by and can not execute.And for discrete narrow band
Resource allocation for, due to the discretization of resource, the instruction of resource more expends bit number than broadband system.So needing one
Kind can extend authorization channel can transmitted bit number authorization.
In addition, due to being also possible to broadband services in discrete frequency point system, it, can be by discrete frequency in order to polymerize bigger bandwidth
Point carries out serial number in logic, to can be carried out the resource authorization of the continuous multiple discrete frequency points of logic, carries out the industry in broadband
Business transmission.Also to the continuity on resource logic, more stringent requirements are proposed for this, reduces resource fragmentation in resource allocation to the greatest extent,
Ensure to have as far as possible in logic continuous frequency point can distribute.And more initiative means are then to allow the semi-static of a part of low priority
Business actively concedes the bandwidth of part occupancy, forms continuous idle frequency band to new high-priority users and carries out resource allocation.
This requires have higher flexibility in authorized appropriation.
Finally, due to be discrete narrow band system, it is contemplated that the electricity-saving characteristic of terminal and the bandwidth ability of radio-frequency filter,
General operating mode is the frequency point that the frequency point that terminal selects some discrete monitors authorization control channel as idle period, at
To be resident frequency point.After having listened to the authorization message of oneself on resident frequency point, then according to the frequency point resource wherein distributed, jump
To the enterprising industry business transmission of specific frequency point, which becomes working frequency points.After if terminal jumps in working frequency points, also
There is authorization to receive, then continues to issue authorization in working frequency points.
Existing authorization is all that one is issued in a wireless transmission chronomere, and carrying information content is limited, is unable to satisfy
The authorization of large information capacity issues demand.And for broadband system, it is possible to accomplish in a wireless transmission chronomere, big
Frequency range in issue multiple authorizations simultaneously, but for narrowband systems, it is clear that be difficult to accomplish.And the authorization of existing system is only
It is divided into unlatching authorization and closes authorization, if to distribute bigger resource to the positive user for carrying out business transmission, only first closes
Then existing transfer resource is then turned on new resource, can not keep business transmission while flexibly adjustment resource, in this way appearance
Existing business service quality is easily influenced, it is also very complicated in process for the scheduling of base station.
Summary of the invention
Goal of the invention of the invention is to be unable to satisfy awarding for large information capacity to overcome prior art carrying information content limited
Power issues the deficiency of demand, and providing one kind can guarantee that nothing can be quickly distributed in the case where terminal reaches demodulation threshold
Line channel resource ensure that terminal uses again compared with being assigned to radio channel resource under short time-delay, while under the premise of this
Throughput of system maximizes criterion, guarantees the radio channel resource distribution in terminal distribution to more reasonable radio channel resource
Method.
To achieve the goals above, the invention adopts the following technical scheme: a kind of superposition of the semi-static transmission of narrowband systems
Authorization method, which is characterized in that including being incremented by authorization sub-step, successively decreasing authorizes sub-step and superposition to authorize what is continuously transmitted to connect
It receives and feedback sub-step；
It is incremented by and authorizes sub-step are as follows: base station and the double hair agreements of terminal, terminal is every obtains a resource unlatching authorization, all
On the basis of having resource allocation, the resource part that do not open in resource authorization is selected, carries out resource expansion；
Successively decrease and authorize sub-step are as follows: closes authorization and carry the specific resource for needing to close, base station and the double hair agreements of terminal, eventually
Every resource progress resource closing for obtaining a resource closing authorization, closing according to the needs wherein indicated is held, and is not turned off
Resource part continues to the transmission of holding business；
The reception and feedback sub-step that superposition authorization continuously transmits are as follows: for the terminal under being in idle condition, if there is N
A continuous authorization issues, then authorization is successively continuously transmitted on residence sub-band, according to the timing relationship between authorization and feedback, most
The authorization for first obtaining ACK feedback, comes into force and jumps at first in the resource of the authorization, carry out the feedback reception of subsequent authorization, after
Continuous authorization sends and retransmits.The present invention proposes a kind of superposition authorization method of semi-static transmission of narrowband systems.It is existing in compatibility
While in the case where system, increasing authorized transmissions information content, while can guarantee business transmission, it is rapidly performed by resource increase
And release, more flexible carry out resource distribution.
Preferably, the terminal not met also is needed for resource, according to current in the incremental authorization sub-step
Resource idle condition distributes the resource bandwidth of a minimum portfolio in advance, is later discovered that the new idling-resource that distributes, then
It issues authorization and carries out resource addition.
Preferably, in the incremental authorization sub-step, new authorization and authorization is distributed, has been overlapped resource or independent money
Source, terminal find out the resource part being not gated in authorization and come into force.
Preferably, the terminal of the ftp business for the type of doing one's best for having occupied vast resources, base station can roots
According to the resource requirement situation of current other higher priority service terminals, resource dynamic is carried out to ftp business terminal and is adjusted, is taken out
Part resource is used to other terminals.
Preferably, for the terminal of existing many GBR/MBR transmission, it is small while meeting basic GBR rate
Amplitude discharges part resource to other users.
Preferably, preceding n authorization is fed back to NACK in the reception and feedback sub-step that superposition authorization continuously transmits,
(n+1)th authorization is fed back to ACK, has issued there are also m authorization receive feedback not yet thereafter, in addition do not had also there are also x authorization
It issues, then the resource of the (n+1)th of terminal authorization comes into force, and terminal jumps to the indicated resource frequency of (n+1)th authorization
The enterprising industry business transmission of point, while the feedback information of subsequent m authorization is received on the resource, n before carrying out on the resource
The re-transmission of authorization carries out the transmission for the first time of remaining x authorization on the resource.
Preferably, demand of the base station according to the utilization of resources, change in resources situation carry out resource unlatching to terminal in real time and award
Power or resource close authorization.
Therefore, the invention has the following beneficial effects: the present invention to propose that a kind of superposition of semi-static transmission of narrowband systems is awarded
Power method.While in the case where compatible existing system, increasing authorized transmissions information content, while can guarantee business transmission,
Resource is rapidly performed by increase and discharge, more flexible carry out resource distribution.
Detailed description of the invention
Fig. 1 is a kind of basic flow chart of the invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
The superposition authorization method (referring to attached drawing 1) of the semi-static transmission of narrowband systems, base station can be to the need according to the utilization of resources
It asks, change in resources situation, multiple resource is carried out to terminal in different moments and opens authorization or resource closing authorization.And simultaneously, eventually
The business at end can be not disrupted, and be continued.Wherein, it is each authorization independently come into force, but repeatedly resource authorization it
Between relationship be not covering and replace relationship, but supplement or extension relationship.Including being incremented by authorization sub-step, successively decreasing and award
The reception and feedback sub-step that power sub-step and superposition authorization continuously transmit.
It is incremented by authorization sub-step:
Base station and the double hair agreements of terminal, terminal is every to obtain a resource unlatching authorization, all existing
On the basis of resource allocation, the resource part that do not open in resource authorization is selected, carries out resource expansion.So base station
It can constantly be discharged according to resource, in the case where having new idling-resource, idling-resource distributed to over time
Carry out business transmission, but have the terminal of more resources demand (such as the ftp business for type of doing one's best).Since terminal is original
Resource can't be interrupted because of new authorization, during entire resource expansion, Business Stream be it is continuous, from small
Traffic transmission it is also very smooth to the transition between big traffic transmission.And certain resources needs are not met also
The terminal of (than the business if any GBR/MBR demand), possible delay requirement is higher, can also take the program, according to current money
Source idle condition distributes the resource bandwidth of a minimum portfolio in advance, is later discovered that the new idling-resource that distributes, then under
Hair authorization carries out resource addition.It is not only more flexible in resource allocation in this way, a large amount of moneys can also will be once transmitted originally
The authorized resolution of source distribution information issues transmission at multiple.Additional benefit is can reduce Grant for resource allocation mistake general
Rate, because if single authorization message it is limited and using multiframe continuously authorize issue joint parse if, as long as there is a frame mistake
Entire authorization message can not then be parsed.And each authorization can individually be parsed and can be come into force in the program, one of mistake
Other authorizations are had no effect on to come into force.And terminal using resource speed faster can be because coming into force in first authorization
Start transmission services, while also can receive subsequent authorization, reuses resource after all receiving without waiting for all authorizations.This
In new authorization and distributed authorization, can not be overlapped, can also be overlapped in resource, terminal only needs to find out in authorization
The resource part being not gated on, is come into force.For example, system has tetra- pieces of resources of A, B, C, D at present, between this three pieces of resources
And be continuously connected.But when the terminal 1 distribution resource, resource block B, C, D are already allocated to other terminals, it is possible to
Authorization 1 first is opened to 1 down distributing resource of terminal, distribution resource block A carries out business transmission.Later, resource C releasing idling is found,
It then descends resource to open authorization 2, distributes resource C.Later, resource B and D while all releasing idling, then base station only needs to issue
Resource opens authorization 3, indicates that resource B~D continuous dispensing to terminal 1, is separately turned on without authorizing to issue in two times
Resource B and resource D.After terminal receives unlatching authorization 3, wherein instruction B~D is distributed for discovery, but the allocated before resource C
It crosses, then the resource B and D that do not open also wherein is subjected to resource unlatching.
Successively decrease and authorize sub-step:
It closes authorization and carries the specific resource for needing to close, base station and the double hair agreements of terminal, terminal
It is every to obtain a resource closing authorization, resource closing is carried out according to the resource that the needs wherein indicated are closed, and not
The resource part of closing continues to the transmission of holding business.
So for having occupied the terminal of the ftp business of the type of doing one's best of vast resources, base station can be according to working as
The resource requirement situation of preceding other higher priority service terminals carries out resource dynamic to ftp business terminal and adjusts, takes out part
Resource is used to other terminals.And the influence interrupted is caused to existing FTP transmitting business stream.And for it is existing very much
The terminal of GBR/MBR transmission, can also take the program, and while meeting basic GBR rate, release part is provided by a small margin
Other users are given in source, and the rate of the user is only showed only as the reduction appropriate between MBR and GBR, but still keeps business continuity
And meet basic transmission demand.
And simultaneously using above-mentioned incremental and authorization of successively decreasing, it can also be real while guaranteeing that terminal traffic keeps transmission
Existing terminal transmission resource is moved.For example user resources are moved from AB to CD, it is only necessary to first add CD, form ABCD and all match
It sets, then deletes AB resource again.
The reception and feedback sub-step that superposition authorization continuously transmits:
For the system of discrete narrow band frequency point, since the frequency point of terminal monitoring authorization channel is limited,
So the subband for monitoring authorization channel under the working sub-band and idle state of terminal is frequently not same subband.It is idle
User under state jumps to the enterprising industry business biography of the frequency point after receiving authorization, further according to the frequency point allocation information of authorization instruction
It is defeated.In order to make to authorize faster transmission, the mode continuously authorized can be taken, and for the authorization of semi-static transmission, in order to protect
Reliability is demonstrate,proved, the retransmission mechanism of feedback and authorization is corresponding with, i.e., if being fed back to NACK illustrates authorized transmissions mistake, needs to carry out
Authorization retransmits.So how under the scene for thering is frequency point to jump, carry out continuous quick authorized transmissions, and guarantee process of feedback and
Authorization retransmits the smooth execution of process, needs to design the timing process of corresponding authorization reception and feedback.
It now provides as follows, the terminal under being in idle condition then successively is being stayed if there is N number of continuous authorization issues
It stays and continuously transmits authorization on subband, according to the timing relationship between authorization and feedback, obtain the authorization of ACK feedback at first, at first
It comes into force and jumps in the resource of the authorization, carry out the feedback reception of subsequent authorization, subsequent authorization sends and retransmits.Before such as
N authorization is fed back to NACK, and (n+1)th authorization is fed back to ACK, has issued there are also m authorization receive feedback not yet thereafter, separately
Outer to issue not yet there are also x authorization, then the resource of the (n+1)th of terminal authorization comes into force, and terminal jumps to (n+1)th and awards
The enterprising industry business transmission of the indicated resource frequency point of power, while the feedback information of subsequent m authorization is received on the resource, at this
The re-transmission of n authorization before carrying out in resource carries out the transmission for the first time of remaining x authorization on the resource.
It should be understood that this embodiment is only used to illustrate the invention but not to limit the scope of the invention.In addition, it should also be understood that,
After having read the content of the invention lectured, those skilled in the art can make various modifications or changes to the present invention, these etc.
Valence form is also fallen within the scope of the appended claims of the present application.
