Description
Technical field
The present invention relates to the communications field, particularly a kind of report method of schedule information, Apparatus and system.
Background technology
At present, in 3GPP Release 7 standards, insert (High SpeedUplink Packet Access at high speed uplink packet, HSUPA) introduced N frequency characteristic in, promptly can there be a plurality of working frequency points a sub-district, one of them working frequency points is the dominant frequency point, and other working frequency points are auxilliary frequency, and travelling carriage (UE) is the single carrier operation pattern; Working frequency points can be on also can the auxilliary frequency in the sub-district on the dominant frequency point of sub-district.The introducing of N frequency notion has promoted the user capacity of system widely, and meanwhile, N frequency characteristic is also laid a good foundation for introducing the multicarrier characteristic among the HSUPA.
Consult shown in the table 1, under the prior art, the schedule information of single carrier HSUPA (SchedulingInformation, structure SI) is as follows:
Table 1
| SNPL (5bits) | UPH (5bits) | TEBS (5bits) | HLBS (4bits) | HLID (4bits) |
Wherein, TEBS (Total E-DCH Buffer Status) represents buffer memory, the buffer memory ratio of HLBS (Highestptriority Logical channel Buffer Status) expression highest priority logical channel, the ID of HLID (Highest priority Logical Channel) expression highest priority logical channel, this three part generally is referred to as buffer status information, the power headroom of UPH (UE Power Headroom) expression terminal, relevant with the residing carrier wave of UE, SNPL (Serving and Neighbour Cell Pathloss) expression service area and adjacent area path loss, also relevant with the network design of the residing working frequency points of UE.
At present, control at Radio Resource (Radio Resource Control, RRC) mode that triggering single carrier SI reports under the CELL_DCH state under can be following any one:
(1) the UE buffer memory becomes greater than 0 o'clock from 0, to the network side SI reporting;
(2) UE be in the switching and buffer memory when empty, to the network side SI reporting;
(3) mandate that obtains of UE is overtime, and the UE buffer memory is not empty, start timer T-WAIT this moment, in the T-WAIT running, UE receives once more when authorizing and stops and replacement T-WAIT, this authorized after date, start T-WAIT, after the T-WAIT timing is overtime, if there is not the schedule information mandate in the estimating window, then trigger by strengthen Random Access Channel (Enhanced Dedicated ChannelRandom Access UplinkControl Channel, E-RUCCH), be also referred to as E-DCH and insert ascending control channel at random, send SI to network side;
Wherein, E-RUCCH is a newly-increased uplink physical channel, the relevant information (being SI) of the assistant base station scheduling of sending out on the transmission user, when UE does not have authorization resources, its SI transmits on E-RUCCH, when UE has authorization resources, its SI in the transmission block that the MAC layer forms incidentally, and (E-DCH Physical Uplink Channel is E-PUCH) on the physical channel to be mapped to E-DCH physical uplink channel.
(4) after SI sends by medium access control e type protocol Data Unit (MAC-e PDU) or medium access control i type protocol Data Unit (MAC-i PDU), start timer T-SI, the overtime triggering of T-SI UE sends SI by E-PUCH; Whenever send a SI by MAC-e PDU or MAC-i PDU, T-SI is restarted;
(5) if UE adopts E-DCH transformat combination (E-DCH Transport FormatCombination, E-TFC) transmission block of Xuan Zeing (TBS) is except the data of carrying logic channel, also exist remaining space can fill SI, then its corresponding MAC-e PDU or MAC-i PDU will carry a SI and be sent to network side;
(6) when UE receives the logical channel data of higher priority, the transmission of SI in MAC-e PDU or MAC-i PDU will be triggered.
Above-mentioned 6 kinds of SI report in the mode, mode (1) and (2) are for authorizing the triggering of (grant request) class, trigger for timer mode (3) and (4), mode (3) is to avoid UE to can not get scheduling for a long time on the work carrier wave, and mode (4) is excessive for fear of UE time interval of reporting scheduling information on carrier wave; Mode (5) triggers for filling (padding) formula; Mode (6) is the triggering of high-priority data.
And along with the development of technology, multi-carrier HSUPA is introduced in the system, the introducing of multi-carrier HSUPA can promote user's up peak rate, make its upstream rate insert (High Speed Downlink PacketAccess with the multi carrier wave high-speed downlink grouping, HSDPA) close, thus can realize up-downgoing speed symmetry.In addition, with respect to N frequency characteristic, the UE in the multi-carrier HSUPA system can use carrier wave more flexibly.
But, the single carrier HSUPA under the N frequency, the introducing of multi-carrier HSUPA has brought many technical problems relevant with carrier wave, and the triggering of SI report flow is exactly one of them under the multi-carrier HSUPA.Because the multicarrier characteristic is different from single carrier, thereby the triggering mode of the SI report flow under the single carrier HSUPA and be not suitable for multicarrier.And the SI of HSUPA system reports trigger mechanism all to be based on the research of single carrier in the existing standard, do not report the relevant research of trigger mechanism with multicarrier SI, and the single carrier algorithm can not be applicable to multicarrier fully, and therefore, the dispatching algorithm of multi-carrier resource needs redesign.

Embodiment
In order under multi-carrier HSUPA, to realize accurately reporting of schedule information, thereby improve the promptness and the flexibility of system resource scheduling, in the embodiment of the invention, with TD SDMA (TimeDivision-Synchronous Code Division Multiple Access, TD-SCDMA) be example, in the TD-SCDMA system, user terminal is provided with trigger condition at network side for a plurality of carrier waves of its configuration, at least one carrier wave of the corresponding appointment of each trigger condition; Described user terminal is monitored each trigger condition that is provided with, and when determining that according to monitoring result a certain trigger condition satisfies, adopt at least one carrier wave of this trigger condition correspondence, the schedule information of all or part of carrier wave that described user terminal is obtained mails to network side.
Wherein, called user terminal is provided with trigger condition at network side for a plurality of carrier waves of its configuration, at least one carrier wave of the corresponding appointment of each trigger condition, comprise: user terminal is divided at least one carrier wave set with network side for a plurality of carrier waves of its configuration, and at each carrier wave set corresponding triggering condition is set respectively; Perhaps, user terminal is each carrier wave in a plurality of carrier waves of its configuration at network side, and corresponding triggering condition is set respectively; Be meant that promptly user terminal can adopt carrier wave set form reporting scheduling information, also can adopt carrier wave absolute version reporting scheduling information.
On the other hand, at least one carrier wave of the corresponding appointment of each trigger condition is meant that the carrier wave of different trigger condition correspondences is inequality, and trigger condition both can corresponding carrier wave, also can the counterpart carrier wave, and can also corresponding whole carrier waves.Be set to timer for example with trigger condition: the corresponding designated carrier of timer (T-SI) that is provided with in order to avoid not carrying schedule information for a long time in data can be that network side is part or all carrier wave that UE distributes, wherein, described data are meant packet or the MAC-i PDU that E-PUCH carries; And in order to avoid UE to have data to be transmitted but can not get the network side scheduling authorization for a long time and the corresponding designated carrier of the timer (T-WAIT) that is provided with can be network side be all carrier waves that UE distributes.
In the practical application, user terminal can be according to network side high-level signaling indication, and perhaps network side and the end side execution pattern of making an appointment is definite with carrier wave set form or carrier wave absolute version reporting scheduling information.Further, user terminal can also be indicated according to the network side high-level signaling, perhaps network side and the end side execution pattern of making an appointment is determined at each carrier wave set corresponding triggering condition to be set respectively, or for each carrier wave of its configuration corresponding triggering condition is set respectively at network side.Further, user terminal whole carrier waves that can will obtain according to the execution pattern that network side and end side are made an appointment put a carrier wave set under.
Preferable, network side is made indication by specific flag information to UE, for example, flag bit is that " TRUE " expression UE need be with the form reporting scheduling information of carrier wave set, flag bit for " FAUSE " then represents UE need be with carrier wave form independence reporting scheduling information independently; Further, network side can also be by the indication of the correlation implicit expression between some signaling UE with carrier wave set or carrier wave form reporting scheduling information independently.On the other hand, high-level signaling can carry above-mentioned indication information by measuring control messages, also can be carried by other dedicated signalings, perhaps with forms of broadcasting notice UE.Like this, after UE receives the high-level signaling indication of network side, just can determine whether according to carrier wave set or carrier wave form reporting scheduling information independently.
Based on above-mentioned principle, network side notice UE is during with the form reporting scheduling information of carrier wave set, can be further with the dividing mode notice UE of carrier wave set.Preferable, UE is divided at least one carrier wave set with network side for a plurality of carrier waves of its configuration according to the carrier wave set information of the high-level signaling configuration that receives, perhaps, UE is divided at least one carrier wave set with network side for a plurality of carrier waves of its configuration according to the neighboring BS information of high-level signaling configuration voluntarily, perhaps, the UE execution pattern of making an appointment according to network side and subscriber terminal side whole carrier waves that will obtain are divided into a carrier wave set.
For example, network side is by high-level signaling notice carrier wave set information, and the purpose of all indicating modes all is to set up mapping relations at carrier wave and under it between the carrier wave set.Below the mode of concrete indication is done some (but being not limited to these execution modes) for example:
(1) carrier wave that comprises of clear and definite each carrier wave set of indication is specifically as shown in table 2,
Table 2
| Carrier wave set information | <1?to?N> | N is the carrier wave set number |
| The carrier set that＞carrier wave set i comprises | The inside comprises the frequency indication or the numbering indication of each carrier wave |
(2) simplify indication, just will belong to extremely the configuration information of same group carrier wave when promptly network side is UE configuration carrier wave, with the continuous position setting, promptly the configuration messages of these carrier waves is adjacent in signaling in signaling.Specifically as shown in table 3:
Table 3
| N bit carrier wave set information | " XXXXXXX " gives an example: " 001101 " expression: carrier wave 1 and 2 is that one group of carrier wave 3 and 4 is that one group of carrier wave 5 is that one group of carrier wave 6 is one group | N is the amount relevant with the carrier wave number, generally gets the value rule that equals carrier wave number 0 and 1 to be: if this carrier wave belongs to same carrier wave set with last carrier wave, then value is identical with last carrier wave, if position different carrier group, then value difference.The value of the bit of first carrier wave correspondence is pressed the initial value setting.Certainly, also can represent identical or different with fixing bit value, promptly, this example can also be expressed as: " 001011 " expression: carrier wave 1 and 2 be one group of carrier wave 3 and 4 be one group of carrier wave 5 be one group of carrier wave 6 be one group wherein 0 the expression with last carrier wave belong to a carrier wave set together, 1 the expression with previous carrier wave belong to the different carrier group.The value of the bit of first carrier wave correspondence is pressed the initial value setting. |
| ... | Other configuration information | |
| The relevant configuration of carrier wave 1 | The numeral here only refers to the sequencing arranged in the signaling. | |
| The relevant configuration of carrier wave 2 | ||
| The relevant configuration of carrier wave 3 | ||
| ... | ||
| The relevant configuration of carrier wave i | I generally gets and equals N |
The configuration information that the basic principle of above-mentioned indicating mode still will belong to the carrier wave of a carrier wave disposes when carrying in signaling continuously, then with the Bit String mapping relations of giving instruction.
(3) show indication, when promptly network side is UE configuration carrier wave, the carrier wave group number in configuration information under this carrier wave of increase.Specifically as shown in table 4:
Table 4
| ... | ||
| The relevant configuration of carrier wave 1 | The numeral here only refers to the sequencing arranged in the signaling. | |
| ＞... .. | ||
| Carrier wave group number under the＞carrier wave 1 |
| The relevant configuration of carrier wave 2 | ||
| ?...... | ||
| Carrier wave group number under the＞carrier wave 2 | ||
| ?...... |
These indication signalings can carry in the measurement control messages, also can be carried by other dedicated signalings, perhaps with forms of broadcasting notice UE.
In addition, UE comprises that for the mode that a plurality of carrier waves of its configuration are divided at least one carrier wave set: UE analyzes one by one at all carrier waves of its acquisition with network side according to the neighboring BS information of high-level signaling configuration voluntarily, which sub-district needed sub-district comprises when judging the SNPL that calculates this carrier wave, when adjacent area that some carrier wave (comprising the situation of having only a carrier wave) uses when calculating SNPL when being identical or close, UE is divided into same carrier wave set with these carrier waves.
In addition, whole carrier waves that UE can also will obtain according to the execution pattern that network side and end side are made an appointment are divided into a carrier wave set, and wherein a kind of application of this mode is the schedule information that can be used to report expansion.
Preferable, when network side needs UE by the carrier wave set reporting scheduling information, by radio network controller (Radio Network Cont, RNC) the carrier wave grouping information of its all carrier waves of informing base station, make the base station after receiving the schedule information of carrier wave set, can derive the schedule information of other carrier waves in this carrier wave set according to the schedule information of receiving on the carrier wave in this carrier wave set, this mode all is suitable for for the schedule information of expansion and the schedule information of non-expansion, indicating mode can be similar with several indicating modes of giving an example above, do not repeat them here.Further, the mode of RNC informing base station carrier wave set information can for: at sub-district foundation or reconfiguration course, Radio Link (RL) foundation or reconfiguration course, Physical Shared Channel foundation or reconfiguration course, Common transport channel foundation or reconfiguration course, (Frame Protocol, FP) frame carries carrier wave set information etc. by Frame Protocol.Preferable, all right informing base station of RNC, UE presses carrier wave set mode reporting scheduling information, or presses carrier wave independent mode reporting scheduling information.
In the embodiment of the invention, UE is when reporting scheduling information, including but not limited to following dual mode:
1, the state of a plurality of carrier waves of side distribution Network Based is expanded the content of schedule information under the single carrier, and the schedule information after will expanding mails to network side.
Table 5
| SNPL 1 (5bits) | ... | ?SNPL m (5bits) | UPH 1 (5bits) | ... | ?UPH n (5bits) | TEBS (5bits) | HLBS (4bits) | HLID (4bits) |
In the parameter that schedule information comprised, SNPL is relevant with the work carrier wave of UE with UPH, therefore, consult shown in the table 5, when expanding the content of schedule information based on the state of multicarrier, UE need be provided with corresponding SNPL and UPH at each carrier wave in a plurality of carrier waves that self use, but because SNPL is can the part carrier wave identical, UPH can derive according to some carrier waves, so the number of SNPL and UPH is unfixing in the schedule information of expansion, be that m equals n or m is not equal to n, and m and n may be 1, and TEBS, HLBS and HLID can share between different carrier.
Above-mentioned table 5 is only given an example for a kind of of expansion schedule information, can also adopt other multiple modes that schedule information is expanded, the basic principle of its expansion promptly is that buffer status information is shared between each carrier wave, and in schedule information, enumerate the SNPL of each carrier wave or carrier wave set, and enumerate the UPH that fixes a carrier wave or enumerate the UPH of the carrier wave that carries this schedule information or enumerate the UPH of each carrier wave.
Schedule information expanded can make the network side base station after receiving schedule information, the schedule information of all working carrier wave that disposable acquisition UE uses is saved operating process.
2, keep the length of schedule information constant based on the single carrier standard.Promptly still adopt mode as shown in table 1 that the content of schedule information is set, and the schedule information of multicarrier is mail to network side by repeatedly transmitting.
Below in conjunction with accompanying drawing the application preferred embodiment is elaborated.
Based on the foregoing description, consult shown in Figure 1, in the embodiment of the invention, the Nei Bao of TD-CDMA system comprises several base stations and user terminal (being UE), base station and RNC are mutual (when network flattening evolution by Iub interface, RNC and base station realize that at same entity Iub interface can keep also and can replace by the intercommunication interface.RNC can have a plurality of base stations under its command, the base station can have a plurality of sub-districts under its command, to the base station transmits data, UE monitors and carries the control channel of scheduling authorization information and to the timely reporting scheduling information of network side the UE of each sub-district in the transmission data procedures with single carrier mode or multi-carrier mode.The channel of reporting scheduling information can be E-RUCCH or E-PUCH, the channel that carries scheduling authorization information is E-DCH absolute grant channel (E-DCH Absolute Grant Channel, E-AGCH), the channel that feed back E-PUCH the base station be E-DCH hybrid ARQ indicating channel (E-DCH Hybrid ARQ IndicatorChannel, E-HICH).Wherein,
UE, be used for for a plurality of carrier waves that this UE disposes trigger condition being set at network side, at least one carrier wave of the corresponding appointment of each trigger condition, and each trigger condition that is provided with monitored, and when determining that according to monitoring result a certain trigger condition satisfies, adopt at least one carrier wave of this trigger condition correspondence, the schedule information of all or part of carrier wave that this UE is obtained mails to network side;
The base station is used for the schedule information that reports according to described UE, for this UE disposes corresponding carrier resource.
Consult shown in Figure 2ly, in the embodiment of the invention, UE comprises and unit 10, detecting unit 11 is set and reports unit 12;
Unit 10 is set, is used for for a plurality of carrier waves that this UE disposes trigger condition being set at least one carrier wave of the corresponding appointment of each trigger condition at network side;
Detecting unit 11 is used for each trigger condition that is provided with is monitored;
Report unit 12, when being used for determining that according to monitoring result a certain trigger condition satisfies, adopt at least one carrier wave of this trigger condition correspondence, the schedule information of all or part of carrier wave that this UE is obtained mails to network side.
Based on the said system framework, to consult shown in Figure 3ly, in the embodiment of the invention, UE is as follows to the detailed process of network side reporting scheduling information (SI):
Step 300:UE is provided with trigger condition at network side for a plurality of carrier waves of its configuration, at least one carrier wave of the corresponding appointment of each trigger condition.
In the present embodiment, UE can be divided into carrier wave set with a plurality of carrier waves that obtain, with carrier wave set form reporting scheduling information, and also can be with carrier wave absolute version reporting scheduling information on a plurality of carrier waves that obtain.Wherein UE is when dividing carrier wave set, can network side be divided at least one carrier wave set for a plurality of carrier waves of its configuration according to the carrier wave set information of the high-level signaling configuration that receives, wherein, described carrier wave set information is the mapping relations between carrier wave and its affiliated carrier wave set; Perhaps, UE is divided at least one carrier wave set with network side for a plurality of carrier waves of its configuration according to the neighboring BS information of high-level signaling configuration voluntarily; Perhaps, the UE execution pattern of making an appointment according to network side and subscriber terminal side voluntarily whole carrier waves that will obtain are divided into a carrier wave set.
For example, UE is according to the cell list of the network side configuration carrier wave set of deriving voluntarily, as, distribute to a plurality of carrier waves of this UE at network side, determine the SNPL of each carrier wave respectively, and the carrier wave of SNPL is equal or similar (being that difference is in setting range) ownership is to same carrier wave set.And for example, UE is at a plurality of carrier waves of network side configuration, and needed adjacent area when searching each carrier wave calculating SNPL if the needed adjacent area of some carrier waves is identical, then belongs to these carrier waves to same carrier wave set.
Again for example, when network side high-level signaling indication UE divides carrier wave set, can be that carrier wave is drawn group by the mode of Bit String, as, just dispose continuously based on the frequency that belongs to same group during for the base station configuration frequency, Bit String shows in " 0 " and " 1 " mode then, the frequency representation of adjacent and identical bit representative belongs to one group, as: " 00010011 " expression: first of configuration is one group to the 3rd carrier wave, independent one group of the 4th carrier wave, the the 5th and the 6th carrier wave is one group, the the 7th and the 8th carrier wave is one group, certainly the indicating mode of Bit String also has other forms, but the coded system difference that only is, different coded systems has all been represented identical mapping relations.Network side is that a plurality of carrier waves that carry of base station configuration can be regarded as complete or collected works, and each carrier wave set of the maintenance of UE all is the subclass of above-mentioned a plurality of carrier waves, and each carrier wave set that base station side is safeguarded also is the complete or collected works of the corresponding carrier wave set of UE side maintenance.
Step 310:UE monitors each trigger condition that is provided with.
When step 320:UE determines that according to monitoring result a certain trigger condition satisfies, adopt at least one carrier wave of this trigger condition correspondence, the schedule information of all or part of carrier wave that UE is obtained mails to network side.Wherein, the schedule information of so-called all or part of carrier wave comprises: send the schedule information of the carrier wave of this schedule information, perhaps, the schedule information of the fixing a certain carrier wave of network side and end side agreement, perhaps, the schedule information of the expansion of all or part of carrier wave of UE acquisition.
In the present embodiment, preferable, when UE determines that according to monitoring result the trigger condition of any one carrier wave set correspondence in each carrier wave set satisfies, in this carrier wave set, receive at first on the carrier wave of scheduling authorization and carry out the transmission of schedule information, or be fixed on the transmission of carrying out schedule information on some carrier waves in this carrier wave set; Preferable, the carrier wave that receives scheduling authorization at first is meant the carrier wave that begins to receive at first in the ensuing time scheduling authorization from timer expired; Preferable, when the trigger condition of any one the carrier wave correspondence that comprises in a plurality of carrier waves that UE determines to obtain according to monitoring result satisfies, on this carrier wave, carry out the transmission of schedule information.
In the above-described embodiments, some trigger conditions of being provided with in step 300 of UE are including but not limited to following several:
1, timer T-SI is overtime.Be UE when timer T-SI is overtime, send the schedule information of all or part of carrier wave that UE obtains to network side.The setting of T-SI is in order to prevent not carry schedule information in the data that UE transmits at least one carrier wave in the T-SI correspondence in T-SI restriction duration.
With the carrier wave set is example, and the maintaining method of the T-SI of certain carrier wave set is: when obtaining scheduling authorization on UE any one carrier wave in this carrier wave set, timer starts; When carrying in the data (E-PUCH or MAC-I PDU) of the Traffic Channel of any one carrier wave of schedule information in this carrier wave set and launching, this T-SI is restarted immediately.The duration of T-SI is disposed by network side, and each carrier wave set can dispose independently T-SI duration, also can dispose unified T-SI duration;
With carrier wave independently is example, and the maintaining method of the T-SI of certain carrier wave is: when UE obtained scheduling authorization on this carrier wave, timer started; When carrying in the data (E-PUCH or MAC-I PDU) of schedule information in the Traffic Channel of this carrier wave and launching, this T-SI is restarted immediately.The duration of T-SI is disposed by network side, and each carrier wave can dispose independently T-SI duration, also can dispose unified T-SI duration;
Be maintained as example with the T-SI that reports the expansion schedule information, the maintaining method of T-SI is: when UE obtained scheduling authorization on any carrier wave, timer started; When schedule information was carried in the data (E-PUCH or MAC-I PDU) of the Traffic Channel of any carrier wave and launched, this T-SI was restarted immediately.The duration of T-SI is disposed by network side.
2, timer T-WAIT, when preventing that user terminal from having data to be sent, in T-WAIT restriction duration, on all carrier waves, all do not obtain the scheduling authorization of network side, at T-WAIT timer expiry and UE buffer memory greater than 0 o'clock, UE will by channel appointed (as, E-DCH inserts ascending control channel at random) schedule information of all or part of carrier wave that will obtain mails to network side.When UE inserts ascending control channel transmission schedule information at random by E-DCH, comprise the schedule information that E-DCH inserts the affiliated carrier wave of ascending control channel at random in the schedule information, or the schedule information of the designated carrier that reports of network side and end side agreement, or the schedule information of expansion.
In the present embodiment, UE safeguards that the method for T-WAIT is as follows: after schedule information inserted ascending control channel at random from E-DCH and carries transmission, T-WAIT will stop and resetting; The all working carrier wave of UE all can not get scheduling authorization in a TTI, and buffer memory is greater than zero the time, and T-WAIT starts; UE has at least a carrier wave to obtain scheduling authorization in a TTI, and T-WAIT will stop and resetting.
Preferable, network side is that UE configuring E-DCH on a carrier wave or a plurality of carrier wave inserts ascending control channel at random, and network side be UE only on a carrier wave configuring E-DCH insert ascending control channel at random for optimum.Network side can insert ascending control channel at random for UE only disposes an E-DCH, be distributed in different carrier and will insert ascending control channel at random, can avoid different UEs when selecting E-DCH to insert ascending control channel emission schedule information at random, to clash like this owing to choosing identical carrier wave for the E-DCH of different UEs configuration.Certainly, network side still can insert ascending control channel at random for UE disposes one group of E-DCH, will select E-DCH to insert ascending control channel (may belong to different carrier) at random when at this moment UE launches schedule information, the principle of selection can be by disturbing size to select or numbering delivery or selection at random by subframe.
And in the above-described embodiments, when UE determines that in step 320 certain trigger condition satisfies, adopt at least one carrier wave of this trigger condition correspondence, when the schedule information of all or part of carrier wave that obtains is mail to network side, can adopt following any one method (is example with the carrier wave set):
1) UE is in current carrier wave set, selects to receive at first the carrier wave reporting scheduling information of scheduling authorization, and E-PUCH or MAC-I PDU by this carrier wave carry schedule information.
2) fixing certain carrier wave reporting scheduling information of selecting in the carrier wave set, E-PUCH or MAC-I PDU by this carrier wave carry schedule information.
Preferable, receive scheduling authorization can refer to receive at first scheduling authorization in the time behind the timer expired carrier wave at first.
Preferable, after determining to carry the carrier wave of schedule information, the UPH that comprises in the schedule information can be the UPH of this carrier wave set, also can be the UPH of some carrier waves of appointment; And comprise in the schedule information SNPL can be the SNPL of this carrier wave set, also can be the SNPL of some carrier waves of appointment.
In like manner, with carrier wave absolute version reporting scheduling information the time, UE also can be provided with a timer T-SI at each carrier wave in a plurality of carrier waves that obtain, and overtime as the precondition that triggers reporting scheduling information with T-SI.
Preferable, UE safeguards a T-SI separately at each carrier wave, does not carry schedule information when the corresponding carrier wave transmitting data for a long time in order to prevent UE; The duration of T-SI is disposed by network side, can dispose independently T-SI duration at each carrier wave, also can be at the unified T-SI duration of a plurality of carrier wave configurations.
Preferable, the maintaining method of the T-SI of above-mentioned each carrier wave is: when UE obtains the scheduling authorization of a certain carrier wave, the T-SI of this carrier wave starts, UE carries the schedule information of this carrier wave in the data (E-PUCH or MAC-I PDU) of the Traffic Channel of this carrier wave and when launching, corresponding T-SI is restarted immediately.
In like manner, when reporting the schedule information of expansion, UE can be provided with a timer T-SI at all carrier waves that obtain, and overtime as the precondition that triggers reporting scheduling information with T-SI.
Preferable, UE safeguards a T-SI at all carrier waves, does not carry schedule information for a long time in order to prevent UE when transmitting data; The duration of T-SI is disposed by network side.
Preferable, the maintaining method of T-SI during the above-mentioned schedule information that reports expansion is: when UE obtains the scheduling authorization of any carrier wave, this T-SI starts, UE carries schedule information in the data (E-PUCH or MAC-I PDU) of the Traffic Channel of any one carrier wave and when launching, corresponding T-SI is restarted immediately.
Based on the foregoing description, UE reserves the space of carrying schedule information when network side sends schedule information in the E-PUCH data packets for transmission, carry out the filling of packet again.UE can carry the schedule information of expansion or non-expansion by the E-PUCH packet; UE can carry schedule information or carrying schedule information on certain fixing carrier wave on the nearest data that transmit on the carrier wave.
In the practical application, in reporting the schedule information process of expansion, when the transmission block size TBS that adopts E-DCH transformat combination (E-TFC) to select as UE is not enough to carry the schedule information of described expansion, can adopt following two kinds of settling modes:
(1) UE can only carry non-expansion schedule information in the E-PUCH packet; Preferable, this schedule information can be the schedule information of fixed carrier, also can be the schedule information of the carrier wave of the schedule information of carrying this non-expansion.
When network side receives upstream data, when the transmission block size can be carried the schedule information of expansion, the base station determines whether to exist schedule information according to the header of packet, when the transmission block size cannot be carried the schedule information of expansion, the base station determines that according to the TBS size schedule information is non-expansion schedule information, and determines the carrier wave attribute of schedule information according to the mode identical with UE;
Preferable, the timer T-SI that safeguard for all carrier waves for user terminal this moment can not restarted, so that in ensuing transfer of data, continue to carry the schedule information of expansion, also can restart, to avoid when the bad channel conditions, the schedule information of continuous triggering expansion, thereby the efficiency of transmission of reduction data.
(2) inferior small data block size (TBS=116) in the restriction transmission block form or bigger TBS are the TBS that E-TFC supports forever, with the situation generation of the schedule information of avoiding carrying expansion.Comprise:
When any carrier wave of UE obtains scheduling authorization, UE judges need carry the expansion schedule information in data, then UE adjusts the minimum TBS of the eternal support that E-TFC chooses, preferable, adjust the minimum TBS that supports forever method can for: will all be set to the E-TFC that supports forever less than all TBS of the minimum TBS of the schedule information that equals to carry expansion in the TBS form; Perhaps, the TBS that UE uses E-TFC to select carries the schedule information of expansion, the value of the TBS of the minimum that agreement is supported forever (as, the TBS=116 of TBSindex=2); Perhaps, adjust in advance minimum TBS value in the TBS form (as, the index of TBS=23 is revised as the schedule information length of expansion, when obtaining scheduling authorization and UE, any carrier wave of UE judges that need carry the expansion schedule information in data the time, the TBS that UE uses E-TFC to select carries the schedule information of expansion in E-PUCH;
The Transport Block Size TBS that selects with E-TFC can be greater than 23 being example below, and it is as follows to introduce the flow process of setting up packet:
Step 1: select suitable TBS according to E-TFC, suppose TBS=1000, the quantity that the carry-on information bit of E-PUCH and data head information and filling bit be described totally 1000.
Step 2: according to TBS group packet, according to priority from high to low order padding data and header, if the schedule information that timer triggers, then priority is the highest during padding data, if for the schedule information of make up the number or amount incidentally (padding), then priority is minimum, the schedule information that priority is the highest will be reserved the space of a schedule information in packet, complete data remaining space is arranged, then carrying the schedule information of a low priority does incidentally, whether this schedule information does not incidentally have space to be preserved, have living space according to data block fully and decide, if also have the bit that remains then can refill a little filling redundancies.
For the schedule information of expansion, need revise the flow process that E-TFC selects in the manner described above, so that the TBS that selects can can hold the schedule information of an expansion when the schedule information of needs dress expansion.
For the schedule information of expansion, when schedule information incidentally, can run into the problem whether remaining space can hold the schedule information of expansion, at this moment principle can be carried the schedule information of how many expansions of the portable band of schedule information of how many expansions.
Wherein, when bag group be preferentially during degree of debuging information, and the placement location of schedule information is all at the packet afterbody,
In the above-mentioned steps 1, the principle of selecting at E-TFC is:
Step 1:UE receives the resource of network authorization, comprises power resource (PRRI), code channel resource (CRRI), time interval resource (TRRI).
Step 2:UE determines gain factor according to the code channel resource of network side configuration
e, UE select network configuration MAC stream power bias (powe offset, maximum PO) is selected the power bias that uses as E-TFC, the minimum and maximum code check of selecting as restriction E-TFC according to the minimum and maximum code check of network configuration;
Step 3: the state of judging all TBS; Support that or does not support; Rule of judgment is:
The β of TBS value corresponding code rate correspondence
0, e+ PO＜=PRRI, and β
0, e+ PO+L+ α
e＜Pmax, and satisfy minimum and maximum code check restriction and modulation system requirement; Wherein Zui Xiao TBS is that TBS=23 is eternal status of support.
Wherein, Pmax is the maximum of uplink transmission power.
Step 4: the maximum TBS that selects all to be in status of support, as the TBS of E-TFC selection.
Be different from the above-mentioned mode of on E-PUCH, reserving free space, in another case, UE is when network side sends schedule information, can also carry the schedule information of expansion or non-expansion to fill (padding) mode by the E-PUCH packet, comprise and detect the remaining space that E-PUCH goes up the packet of current establishment earlier, when determining the schedule information after described remaining space is enough to carry expansion, the schedule information after the expansion is carried at mails to network side in the packet; When determining the schedule information after described remaining space is not enough to carry expansion, the schedule information of part schedule information after the expansion or non-expansion is carried at mails to network side in the packet.
Preferable, the operation of UE can be specially following several operation (can carry the schedule information or the non-expansion schedule information of part expansion when only describing the free space deficiency here for example, perhaps do not carry schedule information, specifically can also segment a variety of operations):
If E-PUCH has free space, can carry the expansion schedule information, then carry the expansion schedule information;
If the free space of E-PUCH can't carry the expansion schedule information, but can carry a non-expansion schedule information, then fill a non-expansion schedule information, this schedule information is the schedule information of place carrier wave, specifically selects which kind of mode also can be made an appointment by network side and end side by the high-level signaling notice.
If the free space of E-PUCH is not enough to carry non-expansion schedule information, then preferentially carry TEBS, HLBS, three information fields of HLID; Perhaps free space does not carry schedule information.
When the base station receives upstream data, when TBS can carry the schedule information of expansion, the base station determines whether to exist schedule information according to the header of packet, when TBS cannot carry the schedule information of expansion, the base station determines that according to the TBS size schedule information is the schedule information of the expansion of part, and determines the carrier wave attribute of schedule information according to the mode identical with the UE of agreement.
In sum, in the embodiment of the present application, in the HSUPA system, introduced based on the triggering of the reporting of scheduling information (SI) of multicarrier characteristic and carried method, can report the schedule information of multicarrier timely and accurately to network side, thereby improve the flexibility of system resource utilization efficient and scheduling of resource.Be specially:
By the carrier wave set reporting scheduling information and report expansion schedule information can reduce reporting of redundant information, improve resource utilization, unify the triggering timing device by all carrier waves and all can not get the scheduling of network side to avoid in the timer duration all carrier waves of user terminal, this mode can reduce the emission probability of E-RUCCH, the E-RUCCH that limits any one UE simultaneously only launches on a carrier wave, and the E-RUCCH of different UEs is configured on the different carrier, can reduce different UEs and choose identical carrier wave at emission E-RUCCH, can avoid interference and conflict, mode by the high-level signaling indication is indicated working method, bring flexibility can for the realization of arrange net work and each manufacturer, therefore, the level of resources utilization and flexibility in the time of can also improving reporting of scheduling information (SI) by method for submitting scheduling information of the present invention.
