Description
Technical field
The invention discloses a kind of method and apparatus for the improved uplink scheduling of cellular transmission system.
Background technology
In particular cellular communication system, there is the channel that not only comprises scheduled transmission but also comprise non-scheduled transmission.An example of this system is TD-SCDMA HSUPA system (access of TD SDMA high-speed uplink), and wherein the example of the channel of mentioned type is E-PUCCH channel (enhancing physical uplink control channel).
In the residential quarter in TD SCDMA system, the resource of the scheduled transmission among the E-PUCCH is controlled by the control node NodeB of residential quarter, and the resource of the non-scheduled transmission in the residential quarter is controlled by the node (being called RNC at TD SCDMA) that is used for wireless network control.The resource of discussing can for example be time slot, channel code and cycle.
Under the situation of scheduled transmission, according to carrying out user from the residential quarter from NodeB " mandate " to the transmission (so-called ul transmissions) of the control node of residential quarter, but not scheduled transmission can not carried out under the situation from the mandate of NodeB.Yet, be still the NodeB of residential quarter from the destination of the non-scheduled transmission of the user in the residential quarter.
In TD SCDMA system, at the uplink traffic in the residential quarter, can use more than a carrier wave, and the NodeB of residential quarter shifts the user between each carrier wave of residential quarter.Yet, because being to use by the resource of RNC rather than NodeB control, non-scheduled transmission carries out, therefore following situation may appear: scheduling and the transmission of non-scheduling uplink at the user, distributed different transmission frequencies to the user.Since the user next at one time interim transmit at two different frequencies, and most of user can not accomplish this point, and this will need same user to have the transmitter of two separation, so this is a problem.
Summary of the invention
Therefore, as mentioned above, need a kind ofly can to overcome the user has the problem of different frequency at scheduled transmission and non-scheduled transmission scheme.The invention provides this scheme, the invention discloses a kind of method of in cellular communication system, using, in described cellular communication system, exist at the control node of each residential quarter and be used at least one node of wireless network control.
The method according to this invention is used more than a uplink carrier frequency at least the first residential quarter, and at least one uplink channel that this first residential quarter has has two types transfer resource: scheduling transmission resources and non-scheduling transmission resources.
Give control to the scheduling resource of described residential quarter to the control node of first residential quarter, and give initial control to the user's of described residential quarter non-scheduling resource to the node that is used for wireless network control.The method according to this invention subsequently, gives control to user's non-scheduled transmission separately or with the user to the control node, uses the uplink carrier frequency identical with user's scheduled transmission with the non-scheduling uplink transmission of guaranteeing the user.
Therefore, the method according to this invention, if the control node with user's scheduling uplink transference to by the node that is used for wireless network control at non-scheduled transmission and original allocation gives user's carrier wave different carrier waves, non-scheduled transmission that then can the mobile subscriber, it is remained on the carrier wave identical with scheduled transmission, and this has eliminated the problem of distributing different frequency to the user at scheduled transmission and non-scheduled transmission.
The invention also discloses a kind of control node that in having used system of the present invention, has used.

Embodiment
Fig. 1 shows the general view of the part that can use system 100 of the present invention.Below will use from the term of TD SCDMA HSUPA technology and describe the present invention, but should be pointed out that this only is for the ease of reader understanding the present invention, and should not be regarded as limiting the scope that the present invention seeks to protect.
Go to Fig. 1 now, show the TD SCDMA residential quarter 110 of using the HSUPA technology.The control node 130 (NodeB) that has residential quarter 110, and the residential quarter is shown has a user 120 (UE, subscriber equipment).Naturally, the number of residential quarter can change in the number of users of every residential quarter and the system, and the number that uses among Fig. 1 is only as example.
Also show node RN C 140 among Fig. 1, RNC is the node in the system, and one of its effect is that wireless network control is carried out in a plurality of residential quarters in the system 100.Should be noted that to exist in the system more than a RNC, although have only a RNC can control the NodeB of same residential quarter or same residential quarter.
As described in starting, in residential quarter 110, have the uplink channel that not only comprises scheduling resource but also comprise non-scheduling resource, and being exemplified as the E-PUCCH channel of TD SCDMA, scheduling resource is controlled by NodeB, and non-scheduling resource is controlled by RNC.Here, term " resource " is used for the set of expression such as resources such as time slot, channel code and cycle.
In TD SCDMA residential quarter, can use a plurality of carrier waves, if the NodeB of residential quarter with the scheduling uplink E-PUCCH transference of UE to the carrier wave different with the carrier wave of the non-scheduling E-PUCCH ul transmissions of this UE, then may go wrong.By the present invention, it is as follows to overcome this problem:
According to the present invention, the control of the specific non-scheduling resource of the E-PUCCH of UE is transferred to NodeB (separately or with UE) from RNC, but RNC will be given the initial control to these resources.Here, use word " initially ": RNC in the sense or by from the one or more message of RNC via NodeB to UE, or undertaken setting up the resource that (being initial configuration) discusses at UE alternately by NodeB and NodeB.
The control of the resource of discussing of UE is transferred to NodeB (separately or with UE), is moved into the carrier wave non-scheduling E-PUCCH transmission configuration carrier wave thereon of UE is identical with RNC with the scheduling E-PUCCH transmission of guaranteeing UE.
From now on, be transferred to NodeB or NodeB and also will be called " half scheduling resource " with the non-scheduling resource of the control of UE.
Fig. 2 shows in the UE, the NodeB that use residential quarter of the present invention and the message between the RNC.At first, for each carrier wave that uses in the residential quarter, RNC will be configured half scheduling transmission resources of carrier wave, and this will be undertaken by the message 1 of Fig. 2.Therefore, message is be used to the message of setting up half scheduling resource.Below will be grouped among Fig. 2 the group that is shown " a " and " b " with the use of describing message 2-8 and with message and combine, come describing message 2-8.
According to the present invention, at transfer and the control of half scheduling resource, two main embodiment are arranged, below these possibilities be called as " numbering " and " do not have numbering ".
Numbering
In the present embodiment, distribute numbering to each half scheduling resource, wherein, in whole the reconfiguring of half scheduling resource, this numbering by RNC, NodeB and UE with for referencial use.Below will describe this alternative in more detail, but in Fig. 3 it be summarized, Fig. 3 shows 3 carrier waves, and one of them is called as main carrier, and two other is sub-carrier number 1 and n, with indication n subcarrier can be arranged in the residential quarter.
Equally as shown in Figure 3, in each carrier wave, half scheduling resource and scheduling resource can be arranged.In this alternative, number 1 to n to each half scheduling resource.Naturally, the use of numbering 1 to n for reference only can utilize letter or symbol to substitute, perhaps, and with reference to the combination that can be one or more numberings, symbol and letter.
In this version, that is, when using " numbering ", the information relevant with the configuration of the non-scheduling resource of carrier wave will be upgraded by message 2, and message 2 is system informations.
In " numbering embodiment ", can pick out two main options.
Numbering, option one
In this option, when UE initially set up the HSUPA connection, RNC came UE is disposed specific half scheduling transmission resources numbering via eNodeB, then, if when and NodeB when moving between with the different carrier of UE in the residential quarter, UE uses half scheduling transmission resources with this numbering in each carrier wave.Therefore, in this option, give the control of half scheduling resource to UE with eNodeB.
When moving between the different carrier of UE in the residential quarter, RNC and NodeB will can not reconfigure the half scheduling transmission resources numbering of distributing to UE.And if when NodeB wanted that UE is dispatched to different carrier waves, NodeB guaranteed at first that in target carrier half scheduling transmission resources with reference numeral is idle.Because half scheduling resource is under the control of NodeB or RNC, therefore this inspection is carried out easily.
The example of this option has been shown among Fig. 4, Fig. 4 show when UE be dispatched to from main carrier situation about taking place when sub-carrier number 1 is dispatched to sub-carrier number n then: UE by original allocation half scheduling transmission resources numbering 2, and when NodeB at first moved to UE sub-carrier number 1 and moves to sub-carrier number 2 then from main carrier, UE kept half scheduling resource with this numbering.
The advantage of this option is not need to send the information relevant with half scheduling transmission resources information to UE.
Numbering, option 2
In the first version (being designated as " a " in the message diagram at Fig. 2) of this option, RNC will dispose one and half scheduling transmission resources numbering or send corresponding configuration information (time slot, channel code, repetition period, repeat length etc.) to UE and NodeB UE and NodeB in the message 3 and 4 of Fig. 1.
Because half scheduling transmission resources numbering is distributed by RNC at first, therefore when state changed, NodeB should report the change of half scheduling transmission resources state to RNC, and this report can be carried out in the message 8 of Fig. 2.It can be that perhaps eNodeB wishes to change by Change Example such as time slot the configuration of UE, and UE is remained on the same carrier owing to for example eNodeB wishes UE is moved to another carrier frequency that this state changes.Therefore, in this option, eNodeB can be considered to control half scheduling resource individually not with UE.
If or when UE switches to another residential quarter, RNC will reconfigure half scheduling transmission resources of UE at Target cell.
In second version (being shown " b " among Fig. 2) of option 2, under the situation from the previous dispatch request of UE not, half scheduling transmission resources numbering or configuration information (time slot, channel code, repetition period, repeat length ...) distributed by NodeB, and in the message 5 of Fig. 1, in first " mandate " in E-AGCH UE is disposed.Therefore, in this option, eNodeB also can be considered to not with UE, controls half scheduling resource individually.
Alternatively, half scheduling transmission resources numbering or corresponding configuration information (time slot, channel code, repetition period, repeat length etc.) can (that is the special message of for this reason creating) send to UE in new message.If or when UE switches to another residential quarter in the system, RNC will can not reconfigure half scheduling transmission resources of UE; But when UE arrives Target cell, the NodeB of Target cell will distribute half scheduling transmission resources.
In this option (i.e. " b "), when NodeB wants that UE moved to different carrier waves, NodeB will at first attempt finding half idle scheduling transmission resources, then, when sending dispatch request to NodeB among the UE message 6 at Fig. 2, in the message 7 of Fig. 2, at E-AGCH for example (in this case, may need new IE is added into E-AGCH) in, NodeB sends the number of free time half scheduling transmission resources in the new carrier wave to UE.NodeB can also reconfigure difference half scheduling transmission resources in the same carrier wave.
The example of this option has been shown among Fig. 5, Fig. 5 shows situation about taking place when UE moves to sub-carrier number 1 and moves to sub-carrier number n therefrom from main carrier: have the free time half of different numberings betwixt the mobile different carrier during scheduling resource when NodeB finds UE, half scheduling transmission resources of UE numbers 2 with half scheduled transmission that the numbering of half scheduling transmission resources from main carrier reconfigures in the sub-carrier number 1, and reconfigures to the half scheduling transmission resources numbering 3 among the sub-carrier number n therefrom.
In this version of the present invention, if or when UE switched to another residential quarter, UE can receive at the NodeB from new residential quarter after the half scheduling resource assignment messages, and use half scheduled transmission to come to send data to the NodeB of new residential quarter.UE can measure (for example time difference of SFN-SFN (system frame number) observation) based on source NodeB and target NodeB timing difference, and determining should be for the timing advance of transmission.
The timing advance that the timing advance of target NodeB can be regarded as the cell-of-origin adds the time difference from the time of reception of the frame of Target cell and cell-of-origin.If between transfer period, there are not data will be sent to NodeB, then before (for example in E-HICH (E-DCH HARQ affirmative acknowledgement indicator channel)) receives response and uplink synchronisation in down link, can send " pseudo-(dummy) " data.Alternatively, pseudo-data can be SI (schedule informations).
In order to keep uplink synchronisation, if (do not have data to be sent to NodeB from UE in the 5ms～80ms), then can use half scheduling transmission resources to send " puppet " data to NodeB long-time.Alternatively, pseudo-data can be SI (schedule informations).
RNC can reconfigure half scheduling transmission resources in each carrier wave of residential quarter.NodeB can also report the state of half scheduling transmission resources, for example percentage of idle half scheduling transmission resources to RNC.RNC can reconfigure half scheduling transmission resources in each carrier wave of residential quarter based on the report from NodeB.
" there is not numbering "
In this second option, under situation about not being numbered, configuration half scheduling resource in each carrier wave.In this option, NodeB distributes to UE with all or part of half scheduling transmission resources in the carrier wave, and in downlink channel (for example E-AGCH, i.e. E-DCH absolute grant channel) this information is sent to UE.
Assignment information can comprise for example carrier frequency, time slot, channel code, repetition period, repeat length etc.If the UE that discusses moves to another carrier wave or be reconfigured (for example by change time slot or channel code in same carrier wave) or call/session termination in same carrier wave, then NodeB will discharge half scheduling resource, that is, NodeB can distribute this resource at other purposes.If UE moves to another carrier wave or is reconfigured, then in downlink channel (for example E-AGCH, i.e. E-DCH absolute grant channel), will in new carrier wave or in same carrier wave, dispose new resources to UE in same carrier wave.In this option, eNodeB also can be considered to not with UE, controls half scheduling resource individually.
