Description

Relative authorization value method for confirming mapping relation and device
Technical field
The present invention relates to the communications field, in particular to a kind of relative authorization value method for confirming mapping relation and device.
Background technology
High speed uplink packet inserts (High Speed Uplink Packet Access abbreviates HSUPA as) through effectively utilizing power, when channel condition is good, improves the message transmission rate of terminal to the up direction of Access Network.The key technology of HSUPA is: the automatic re-send request may of mixing (Hybrid Automatic Repeat Request; Abbreviate HARQ as), the fast dispatch of Node B, 2 milliseconds Transmission Time Interval (Transmission Time Interval abbreviates TTI as).
The fast dispatch technology is advanced to Node B with the scheduling of being responsible for by radio network controller in the legacy wireless communication system.At each TTI, the terminal is reported the information such as the current available horsepower of outgoing data amount and terminal in the current terminal buffers through uploading schedule information to Node B.Node B is according to Node B fast dispatch algorithm; Just wait the data volume sent out according to the load of sub-district and cell uplink disturbed condition, terminal; The channel quality that scheduling strategy, the terminal of the upper limit of terminal capability and Node B self is current etc.; Decide the current operable maximum ascending resource in terminal (having determined the current available maximum transmission rate in terminal), and inform the terminal through the mode that issues scheduling authorization (Scheduling Grant).Can significantly reduce the round-trip delay of dispatch through this processing, make dispatching response fast, good utilisation air-link resources more, thus improve throughput of system.
Scheduling authorization is the control signaling that on down direction, is sent to the terminal by Node B, has following characteristic:
Scheduling authorization only is used to strengthen transformat associating (Enhanced Transport Format Combination abbreviates E-TFC as) selection algorithm.
Scheduling authorization has been controlled maximum enhanced dedicated channel Dedicated Physical Data Channel/Dedicated Physical Control Channel (Enhanced Dedicated Channel (E-DCH) Dedicated Physical Data Channel/Dedicated Physical Control Channel abbreviates E-DPDCH/DPCCH as) power ratio of transmission data in the HARQ process that activates.
2 types mandate is provided: absolute grant and relative authorization.The up maximum power resource that absolute grant provides the terminal to use is the E-DPDCH/DPCCH power ratio of the maximum permission use of HARQ process each time.Relative authorization representes that terminal rise on the power resource basis that preceding once scheduling is used perhaps reduces by a relative value; The relative authorization of service specifically comprises UP (rise), HOLD (remaining unchanged), these 3 kinds of values of DOWN (minimizing), and the relative authorization of non-service specifically comprises HOLD (remaining unchanged), these 2 kinds of values of DOWN (minimizing).
In the prior art, Node B is sent absolute grant with reference to absolute grant value mapping relations table one (that is, as shown in table 1 table) or absolute grant value mapping relations table two (that is, as shown in table 2 table).

Node B is sent the relative authorization of service, and the relative authorization of service specifically comprises UP (rise), HOLD (remaining unchanged), these 3 kinds of values of DOWN (minimizing).Node B is sent the relative authorization of service with reference to table 3 or table 4; Calculate the reference power ratio; Go out the scheduling authorization value of expectation according to Node B fast dispatch algorithm computation; Scheduling authorization value and the reference power ratio of expectation are compared, and judgement should be raised, remain unchanged and still reduce on than the basis at reference power, sends the relative authorization of corresponding service then and controls signaling.Wherein: reference power has among the previous TTI of identical HARQ process than being meant with this data transfer, is used for the E-DPDCH/DPCCH power ratio that E-TFC selects.
Node B is sent the relative authorization of non-service, and the relative authorization of non-service specifically comprises HOLD (remaining unchanged), these 2 kinds of values of DOWN (minimizing).Node B is sent the relative authorization of non-service with reference to table 3 or table 4; Calculate reference record and preserve power ratio; Go out the scheduling authorization value of expectation according to Node B fast dispatch algorithm computation; Scheduling authorization value and the reference record of expectation are preserved power ratio compare, judgement should remain unchanged on reference record is preserved the basis of power ratio and still reduce, and sends the relative authorization of corresponding non-service then and controls signaling.Wherein: reference record is preserved power ratio and is meant with this data transfer to have among the previous TTI of identical HARQ process, is used for this new value that E-DPDCH/DPCCH power ratio that E-TFC selects is updated to new value time institute recorded and stored.
The modulation system that HSUPA uses has two kinds: QPSK (Quadrature Phase Shift Keying; Abbreviate QPSK as) and the amplitude-phase of 16 sampling points unite modulation (16Quadrature Amplitude Modulation abbreviates 16QAM as), wherein; 16QAM is a kind of digital high-order modulating; The amount of information of each symbol is 2 times of QPSK, and with respect to the common modulation system of QPSK, 16QAM can more efficient use channel width.The introducing of 16QAM high-order modulating makes and need introduce the requirement that higher authorization value could satisfy higher rate.
In engineering application, some problems can appear in the utilization scene for commonly used modulation system, particularly 16QAM of HSUPA, cause the decline of systematic function, below are that example describes with the application scenarios of 16QAM:
Node B activates the 16QAM operation of Radio Link, consults and uses table 1 (absolute grant value mapping relations table one) and sends absolute grant, and consult and use table 4 (scheduling authorization table two) and send relative authorization.When then subsequent node B utilization absolute grant and relative authorization are notified the terminal, may there be following two kinds of situation:
It is that call number 2 is given the terminal that situation 1, Node B are sent absolute grant, consults and uses table 1 (absolute grant value mapping relations table one), and call number 2 corresponding absolute grant values are (7/15) 2Follow-up, Node B goes out the scheduling authorization value of expectation based on Node B fast dispatch algorithm computation, the scheduling authorization value of expectation is preserved power ratio with reference power ratio or reference record compare, and hopes to reduce or reduce power ratio.But this moment, because Node B is to consult and use table 4 (scheduling authorization table two) to generate relative authorization, and the minimum particle size of table 4 is (11/15) 2, obviously, Node B can't notify the terminal to reduce through relative authorization.
It is that call number 31 is given the terminal that situation 2, Node B are sent absolute grant, consults and uses table 1 (absolute grant value mapping relations table one), and call number 2 corresponding absolute grant values are (168/15) 2X6.Follow-up, Node B goes out the scheduling authorization value of expectation according to Node B fast dispatch algorithm computation, the scheduling authorization value of expectation is preserved power ratio with reference power ratio or reference record compare, and hopes to raise power ratio, for example fully uses 16QAM until (377/15) 2X4.So, Node B is merely able to select to use the UP control signaling of relative authorization to notify one-level one-level ground, terminal toward rise, and can not directly use absolute grant, because this moment, the absolute grant value was (168/15) 2X6 has been the maximum particle size of table 1 (absolute grant value mapping relations table one).Equally, if Node B hope from (377/15) 2X4 drops to (168/15) 2X6 also is merely able to notify one-level one-level ground, terminal to decline through the DOWN control signaling of relative authorization.The processing of every many one-levels all is to have increased at least one times processing delay, and is bigger for performance impact, can't guarantee to come timely response terminal through fast dispatch, lost the meaning of Node B fast dispatch.
It is thus clear that; Scheduling authorization scheme of the prior art is when engineering application; Because therefore the mapping relations of the relative authorization value of using when Node B possibility picked at random is used to handle the relative authorization signaling, just may exist the relative authorization that can't adopt of above description to notify the terminal current operable maximum ascending resource; Perhaps need notify the situation of the current operable maximum ascending resource in terminal, thereby influence the performance of HSUPA system through relative authorization repeatedly.

Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.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.
Present embodiment provides a kind of relative authorization value method for confirming mapping relation; Comprise: Node B is confirmed and the corresponding relative authorization value of current absolute grant value mapping relations mapping relations according to absolute grant value mapping relations of formulating in advance and the corresponding relation between the relative authorization value mapping relations.
Through this method; According to the corresponding relation of formulating in advance; Confirm to adopt with the corresponding relative authorization value of current absolute grant value mapping relations mapping relations as the foundation of Node B when handling the relative authorization signaling (; Node B is employed relative authorization value mapping relations when handling the relative authorization signaling); In prior art, choose relative authorization value mapping relations randomly, can promote the performance of HSUPA technology in engineering application, solved the problem of selecting relative authorization value mapping relations to influence the HSUPA systematic function at random.
In this method, the corresponding relation of formulating in advance can be the absolute grant value mapping relations and corresponding being in the same place of relative authorization value mapping relations that scheduling scope and scheduling granularity are matched each other, and this relation can be corresponding one by one, one-to-many, or many-one.As long as there is such corresponding relation of formulating in advance; Just can confirm the relative authorization value mapping relations of use according to this corresponding relation; And need not to select at random; Thereby just can solve the problem of selecting relative authorization value mapping relations to influence the HSUPA systematic function at random, thereby promote the performance of HSUPA technology in engineering application.The embodiment of the invention has been enumerated following two kinds of exemplary corresponding relations based on above-mentioned table 1-4:
(1) corresponding between absolute grant value mapping relations table one and the scheduling authorization table one, correspondingly, Node B is using absolute grant value mapping relations table one to shine upon under the situation of absolute grant, and then Node B uses scheduling authorization table one to handle the relative authorization signaling.
Using absolute grant value mapping relations tables one (specifically as shown in table 1) to shine upon under the situation of absolute grant, Node B uses scheduling authorization table one (specifically as shown in table 3) to handle the relative authorization signaling when needs are handled the relative authorization signaling.Because absolute grant value mapping relations table one and scheduling authorization table one have good matching relationship on adjusting range and adjustment granularity, therefore prevented situation 1 and situation 2 effectively, thereby promoted the performance of HSUPA technology in engineering application.
In this process; The situation that adopts absolute grant value mapping relations table one to shine upon absolute grant possibly be the result that Node B is carried out the order of network side; For example: Node B receives from the instructs node B that is used for of radio network controller uses absolute grant value mapping table one to shine upon NBAP (the Node B Application Part of absolute grant; Node B application part provides the signaling of the control between radio network controller and the Node B) layer control signaling.In this signaling; Can adopt indicating bit to express such indication implication; For example, in NBAP layer control signaling, carry " selection of enhancement type special channel absolute grant channel table " cell, and this cell value is when being " absolute grant value mapping relations table one "; Then Node B uses " absolute grant value mapping relations table one " to shine upon absolute grant, belongs to Node B and is using " absolute grant value mapping relations table one " to shine upon the situation of absolute grant.
(2) absolute grant value mapping relations table two is corresponding with scheduling authorization table two, and correspondingly, Node B is using absolute grant value mapping relations table two to shine upon under the situation of absolute grant, and then Node B uses scheduling authorization table two to handle the relative authorization signaling.
Using absolute grant value mapping relations tables two (specifically as shown in table 2) to shine upon under the situation of absolute grant, Node B uses (specifically as shown in table 4) to handle the relative authorization signaling when needs are handled the relative authorization signaling.Because absolute grant value mapping relations table two and scheduling authorization table two have good matching relationship, thereby have promoted the performance of HSUPA technology in engineering application on adjusting range and adjustment granularity.
In this process; The situation that adopts absolute grant value mapping relations table two to shine upon absolute grant possibly be the result that Node B is carried out the order of network side; For example, Node B receives from the instructs node B that is used for of radio network controller and uses absolute grant value mapping table two to shine upon the NBAP layer control signaling of absolute grant.In this signaling; Can adopt indicating bit to express such indication implication; For example, in NBAP layer control signaling, carry " selection of enhancement type special channel absolute grant channel table " cell, and this cell value is " an absolute grant value mapping relations table two "; Then Node B uses absolute grant value mapping relations table two to shine upon absolute grant, belongs to Node B and is using absolute grant value mapping relations table two to shine upon the situation of absolute grant.
Through two kinds of above corresponding relations; Make Node B that absolute grant value mapping relations table one and scheduling authorization table one is interrelated and be used; And/or it is absolute grant value mapping relations table two and scheduling authorization table two is interrelated and be used; Thereby make the Node B power ratio that can use of scheduling controlling terminal exactly, promoted the performance of HSUPA technology in engineering application.
In HSUPA,, adopt scheduling authorization table one to handle the relative authorization signaling because QPSK adopts absolute grant value mapping relations table one to shine upon the absolute grant signaling usually; Therefore, can not adopt said method to handle, and because 16QAM adopts the mode of selecting at random usually; Therefore; Can, Node B handle according to the method described above, thereby solve the serious problem of performance degradation under the 16QAM situation when activate the up 16QAM operation of Radio Link.
Above Node B is to the activation of the up 16QAM operation of Radio Link; Possibly be that network side is initiated; Concrete; Node B possibly be to receive from being used for after the NBAP layer control signaling of up 16QAM operation that instructs node B activates Radio Link of radio network controller, carries out the activation of 16QAM operation.Can in NBAP layer control signaling, carry cell and represent this indication implication; For example; Carry up 16QAM operation indication information element in NBAP layer control signaling, and this cell is set to the value of " activation ", the up 16QAM operation of Node B activation Radio Link so.
Preferably; After definite and the corresponding relative authorization value of current absolute grant value mapping relations mapping relations; Node B can also use definite relative authorization value mapping relations to handle the relative authorization signaling; Thereby under the condition that guarantees systematic function, accomplish adjustment to the current operable maximum ascending resource in terminal.
For above corresponding relation of giving an example (1); Node B uses scheduling authorization table one to handle the relative authorization signaling; Can be that Node B is sent the relative authorization of serving with reference to scheduling authorization table one, the relative authorization of service specifically comprises UP (rise), HOLD (remaining unchanged), these 3 kinds of values of DOWN (minimizing); Perhaps, can be meant the relative authorization of Node B with reference to the non-service of scheduling authorization table one transmission, the relative authorization of non-service specifically comprises HOLD (remaining unchanged), these 2 kinds of values of DOWN (minimizing).
For above corresponding relation of giving an example (2); Node B uses scheduling authorization table two to handle the relative authorization signaling; Can be that Node B is sent the relative authorization of serving with reference to scheduling authorization table two, the relative authorization of service specifically comprises UP (rise), HOLD (remaining unchanged), these 3 kinds of values of DOWN (minimizing); Perhaps, can be the relative authorization of Node B with reference to the non-service of scheduling authorization table two transmission, the relative authorization of non-service specifically comprises HOLD (remaining unchanged), these 2 kinds of values of DOWN (minimizing).
Fig. 1 is that this device comprises according to the structured flowchart of definite device of the relative authorization value mapping relations of the embodiment of the invention: formulate module 12, be used to formulate the corresponding relation between absolute grant value mapping relations and the relative authorization value mapping relations; Determination module 14 is coupled to and formulates module 12, is used for confirming and the corresponding relative authorization value of current absolute grant value mapping relations mapping relations according to corresponding relation.In this device, determination module 14 can be arranged in Node B.
Preferably, determination module 14 is used for using absolute grant value mapping relations table one to shine upon under the situation of absolute grant, confirms that Node B uses scheduling authorization table one to handle the relative authorization signaling when needs are handled the relative authorization signaling; Using absolute grant value mapping relations table two to shine upon under the situation of absolute grant, confirming that Node B uses scheduling authorization table two to handle the relative authorization signaling when needs are handled the relative authorization signaling.
