Abstract
Communications are received from a user equipment UE on an uplink enhanced dedicated channel E-DCH. The radio resources of at least one downlink channel that supports the E- DCH are either released or configured or reconfigured while the E-DCH is maintained for the UE. The downlink channels may be E-AGCH, E-HICH, or E-RGCH, and the radio resources may include a temporary identifier E-RNTI, signature sequence, and/or channelization codes. At a serving cell change of the UE, either or both of the serving cell and the non-serving cell can add/configure/reconfigure a supporting downlink channel, all without t&minating the E-DCH. The UE and the SRNC are notified by an E- RGCH release indicator whether the E-RGCH is released or not at a serving cell change, and the UE deletes its stored E-RGCH parameters when the release indicator indicates it is released.

For 3GPP, agreement will have two kinds of dispatching methods.These methods are to use the absolute grant method of E-AGCH and use the relative authorization method of E-RGCH.E-AGCH shares downlink channel, and it is used to provide with UE can be used for the quantity of the uplink resource of E-DCH, how many data (data rate) and the relevant absolute limitations of maximum power that scheduling UE can send.E-RGCH replenishes E-AGCH and is used for increasing or reduce scheduling rates and/or the power that UE sends than previous authorization value (for example authorizing on the E-AGCH or authorizing according to previous order on the E-RGCH) on E-DCH.Send E-AGCH from the only sub-district that is called the E-DCH Serving cell.Can send E-RGCH from each sub-district of E-DCH active set, promptly and do not require from all sub-districts of E-DCH active set and send E-RGCH.Then leaving Node B for for UE configuration E-RGCH resource implements.E-HICH is mixed automatic repeat request (HARQ) channel, and this is to be used for confirming that by the HARQ process E-DCH goes up the physical channel from the transmission of user's equipment.This makes up link have more elasticity to signal error by allowing to retransmit the grouping that makes mistakes as Node B is asked with affirmation or Negative Acknowledgement.
Consider E-RGCH, service relative grant and non-service relative grant can be arranged on this shared physical channel.The service relative grant of transmitting on down link E-RGCH allows Node B to be adjusted in the mandate speed of the UE under its control from any sub-district in the service E-DCH RL service.Usually, the order that is used for service relative grant is " UP (liter) ", " DOWN (falling) " or " HOLD (maintenance) ".On down link E-RGCH, also transmit non-service relative grant.This allows neighbor node B to regulate not transmission rate at the UE of (for example in the neighbor cell under the control in serving node B) under its control in order to avoid overload situations.Usually, the order that is used for non-service relative grant is " HOLD " or " DOWN ".A plurality of non-service relative grant can once send to UE (because have under the control of the non-serving node B of difference a plurality of neighbor cells), and only can have a service relative grant to send to UE (from its Serving cell of dispatching as serving node B) any time according to being defined in.
In current standard, only when setting up E-DCH, just dispose E-RGCH, and do not have to specify in order to setting up E-DCH after, in Node B, to discharge, to dispose and reconfigure the technology of E-RGCH, promptly require Node B to use same E-RGCH to dispose and be released or deleted until RL until E-DCH.Anti-speech, when setting up, do not dispose E-DCH under the situation of E-RGCH in Node B, and Node B does not have E-RGCH and is released until E-DCH.
Because E-DCH is a new feature for 3GPP, so before the present invention, there is not gratifying solution at foregoing problems.

Embodiment
The inventor has realized that the above-mentioned suggestion scheduling of mentioning implements to change in the Serving cell process and produce following problem afterwards at UE in background technology.
1) do not have under the situation of E-RGCH and when it becomes non-service cell at Serving cell, under the sub-district Node B will wish configuration E-RGCH in case reduce RoT in the sub-district (RoT be illustrated in Node B from the ratio of the gross power of radio sources reception and thermal noise and be well known in the art).Yet, can not dispose E-RGCH, so Node B can not reduce the RoT that UE generates in the sub-district.
2) have under the situation of E-RGCH and when it becomes non-service cell, Node B will wish to discharge E-RGCH under the sub-district at Serving cell, because Node B is not supported the E-RGCH from the non-RL of service collection.Yet, can not discharge E-RGCH in this case, because must keep E-RGCH resource (code and signature sequence), even E-RGCH never is sent to UE.
3) have under the situation of E-RGCH and when it becomes non-service cell at Serving cell, Node B will be wished only to distribute to from code/signature sequence to E-RGCH " special-purpose E-RGCH " condition of a UE will be reconfigured for " shared E-RGCH " condition that code/signature sequence is distributed to a plurality of UE under the sub-district.Yet, can not dispose E-RGCH in this case, because Node B must send " special use " E-RGCH (overload indicator) that is used to reduce RoT, this is the waste to E-RGCH resource and DL radio resource.
4) do not have under the situation of E-RGCH and when it became Serving cell, Node B had hope the E-RGCH of E-AGCH in the supplemental services Node B under the sub-district at non-service cell.Yet, can not dispose E-RGCH in this case, because Node B must be used E-AGCH always, even its supports the E-RGCH from service RLS.
5) have under the situation of E-RGCH and when it becomes Serving cell, Node B will be wished release E-RGCH under the sub-district at non-service cell.Yet, can not discharge E-RGCH in this case, because must keep the E-RGCH resource, even E-RGCH never is sent to UE.
6) have under the situation of E-RGCH and when it becomes Serving cell, Node B will wish E-RGCH is reconfigured as " special-purpose E-RGCH " from " shared E-RGCH " under the sub-district at non-service cell.Yet, in current standard, can not reconfigure E-RGCH, because Node B must replace use " shared " E-RGCH.
The discussed above first and the 3rd problem is crucial especially problem.Exemplary embodiment of the present invention is devoted to the other problem that solves the first and the 3rd problem and above enumerate.
These and similar problem may take place for E-AGCH/HICH in attention, because will use the same channelization code of E-AGCH in the Serving cell and E-RNTI to become non-service cell or E-DCH is released until Serving cell.To use same channelization code and the signature sequence of E-HICH to be released until E-DCH.Be used for the code of E-AGCH and E-HICH and signature sequence to reconfigure for the system that implements VoIP by HSUPA be essential because may for example expect that 100 UE are in the sub-district and reconfigure the benefit that may realize saving code and signature resources.Generally speaking, channelization codes, signature sequence, casual network identifier and other parameter (parameter channel configuration or the network identifier that are used for UE) that comprise the radio link (for example E-RGCH or E-HICH) that is used between UE and Node B (perhaps RNC) as term used herein " radio resource ".

The utilization of exemplary embodiment of the present has realized when Serving cell changes and has more generally discharged, disposed and reconfigure E-RGCH/HICH at any required time.
The exemplary embodiment (A)-(D) that is used for discharging the E-RGCH resource when Serving cell changes is discussed earlier.
A) when carrying out service E-DCH RL change (sub-district becomes non-service cell or opposite from Serving cell), Node B 12 indicates whether to discharge E-RGCH (for example E-RGCH discharges designator) to SRNC 14.
B) when carrying out service E-DCH RL change, Node B 12 discharges E-RGCH (for example E-RGCH discharges designator) to SRNC 14 indications.It should be noted that if Node B 12 does not discharge E-RGCH, then Node B 12 need not to indicate to SRNC 14 at all.
C) when carrying out service E-DCH RL and change, Node B 12 is one of following three to SRNC 14 indications:
A. the new configuration parameter of the E-RGCH that reconfigures E-RGCH and be used to reconfigure (for example channelization codes and signature sequence);
B. keep E-RGCH (for example negating to discharge designator); Perhaps
C. discharge E-RGCH (for example discharging designator certainly).
D) Node B 12 wishes to discharge current E-RGCH to SRNC 14 instructs node B at any time, is included in when carrying out E-DCH RL change.
Can note can't see the situation that in Serving cell, discharges E-HICH and discharge E-AGCH.
Discuss now and be used for when Serving cell changes, disposing and reconfiguring the exemplary embodiment (A) of E-RGCH/E-HICH and (B).
A) when carrying out service E-DCH RL change, Node B 12 indicates whether configuration (with reconfiguring) E-RGCH/E-HICH to SRNC 14.In addition, when Node B 12 indication configuration or when reconfiguring E-RGCH/E-HICH, will be used for configuration parameter (for example channelization codes and the signature sequence of E-RGCH/E-HICH.) send to SRNC 14.
B) Node B 12 (is included in when carrying out E-DCH RL change) at any time to SRNC 14 instructs node B 12 and wishes to dispose/reconfigure E-RGCH/E-HICH/E-AGCH.Can note having only by using this embodiment just to make reconfiguring of E-AGCH become possibility.
Receive from Node B 12 at SRNC 14 to dispose/reconfigure request after, SRNC 14 sends to UE 10 and disposes/reconfigure request.
Implement about foregoing example, particularly in embodiment (A), when Serving cell changes, discharge E-RGCH, can define to SRNC 14 and indicate the new IE that whether discharges E-RGCH.This IE can be positioned in order in the response message of carrying out the message request that Serving cell changes (RNSAP/NBAP for example: the radio link ready and radio link of orchestration again reconfigures response).Preferably in the RRC message that is used to notify UE 10 (, reconfiguring in the message), also introduce new IE at physical channel as a unrestricted example.
In 3GPP TS 25.433 V6.6.0 (2005-06) (third generation partnership projects; The technical specification group radio access network; UTRAN Iub interface node B application part (NBAP) signaling (the 6th edition)) under the background of table 9.1.43 (the 212nd page), figure 2 illustrates an example that uses E-RGCH to discharge designator IE (being expressed as 100).
Fig. 3 shows the example embodiment that E-RGCH discharges the IE/ packet name of designator and IE type and quotes.
With reference to the exemplary enforcement that is used for when Serving cell changes discharging the embodiment (B) of E-RGCH resource discussed above, can be at the new IE that has indicated release E-RGCH at introducing in order to the response message of carrying out the message request that Serving cell changes (RNSAP/NBAP for example: radio link reconfigures ready and radio link and reconfigures response).Preferably in the RRC message that is used to notify UE 10 (, reconfiguring in the message), also introduce new IE at physical channel as a unrestricted example.
About the exemplary enforcement that is used for when Serving cell changes discharging the embodiment (C) of E-RGCH resource discussed above, can at introducing in order to the response message of carrying out the message request that Serving cell changes (RNSAP/NBAP for example: radio link reconfigures ready and radio link and reconfigures response) in order to indicate following one of every new IE:
A. dispose or reconfigure E-RGCH;
B. keep E-RGCH; Perhaps
C. discharge E-RGCH.
This new IE also preferably includes following IE, and this IE carries the configuration parameter (for example channelization codes and E-RGCH signature sequence IE) of the E-RGCH that is used to reconfigure, and perhaps existing E-DCH FDD DL control channel information IE can carry configuration parameter.Preferably in the RRC message that is used to notify UE 10 (, reconfiguring in the message), also introduce new IE at physical channel as a unrestricted example.
With reference to the exemplary enforcement that is used for when Serving cell changes, discharging the embodiment (D) of E-RGCH resource discussed above, can introduce new IE and wish to discharge E-RGCH in order to instructs node B 12.This IE can be positioned in the existing NBAP/RNSAP radio link parameters updating message or in the new RNSAP/NBAP message.NBAP/RNSAP radio link parameters updating message can find in the 8.3.19 joint (the 140th page) of TS25.433 v6.6.0.In order to answer Node B 12, can introduce another new IE in order to discharge E-RGCH to Node B 12 indication SRNC 14 requests.The existing RNSAP/NBAP radio link that can stipulate in the table 9.1.42 of TS25.433 v6.6.0 and 9.1.47 reconfigures and introduces this new IE in parameter/request message.Preferably in the RRC message that is used to notify UE 10 (, reconfiguring in the message), also introduce new IE at physical channel as a unrestricted example.
About the exemplary enforcement that is used for the embodiment (A) of when Serving cell changes (again) configuration E-RGCH/HICH discussed above, can use with above at the new IE similar new IE of embodiment A with the C discussion.Can in new IE or in existing E-DCH FDD DL control channel information, carry the configuration parameter that is used to the E-RGCH/HICH that disposes/reconfigure.
Implement about the example that is used for the embodiment (B) of (again) configuration E-RGCH/HICH when Serving cell changes discussed above, can use and the similar new IE of new IE that above discusses at embodiment D.
The present invention is non-limiting have been realized discharging unnecessary E-RGCH resource when the E-DCHRL Serving cell changes when carrying out with utilization exemplary embodiment, and these resources therefore avoid waste.The present invention is non-limiting also have been realized disposing or reconfiguring unnecessary E-RGCH resource and make Node B 12 can continue to use E-RGCH when E-DCH RL Serving cell changes when carrying out with utilization exemplary embodiment.In addition, in the RNSAP/NBAP signaling, need not to introduce new process or message, because in standard, only need to introduce one or more new IE in the existing message (such as discussed above and discharge designator IE) at the E-RGCH shown in Fig. 2 and Fig. 3.
Fig. 4 illustrates the operation of various nodes in an example embodiment that relates in the diagram.RNC 14 as previously mentioned.Node B is by first base station BS 1 12 (for example serving node B of MS before Serving cell changes) and second base station BS 2 12 ' (for example non-serving node B before Serving cell changes).Represent under the situation of different nodes B at two base station BSs 1 12 and BS2 12 ', they can be under the control of single RNC (Serving RNC) or under can the control in different RNCs.Mobile radio station MS 10 is from moving to the second place 31 ' under the control of the 2nd BS2 12 ' in the primary importance under the control of a BS 12, on behalf of the Serving cell of MS 10, this change.Embodiments of the invention are not limited to Serving cell and change, though as described here this for the release that starts radio resource, dispose and/or reconfigure that to be that comparison is convenient take place.
Before changing, Serving cell sets up dedicated channel E-DCH (may before change to a BS1 12) for MS 10 for Fig. 4 hypothesis though set up the MS 10 of E-DCH by serving BS broadcasts 1 12.The one BS1 12 is MS 10 (when it is serving node B) configuration absolute grant channel E-AGCH 32 and relative authorization channel E-RGCH 34, and these channels are provided with data rate that UE is allowed to use respectively on E-DCH and the absolute maximum and the BS1 12 of power can order the relative adjustment/increment of UE to this maximum at any time based on the change condition in the sub-district.Also show down link E-HICH37,37 ' in Fig. 4, this down link is used for pointing out MS 10 to resend the data that before correctly do not receive at BS 12 by BS.E-AGCH, E-RGCH and E-HICH respectively use radio resource, and such as enhanced wireless electric network temporary identifier E-RNTI, channelization codes and/or the signature sequence etc. that are used for those downlink channel, and such resource is limited to any certain base station.These downlink configuration parameters that SRNC 14 notice MS 10 receive from BS 12 (for example signature sequence, channelization codes, distribute to MS 10 in order at its E-RNTI of these downlink channel signs) so as MS 10 can stored parameter and monitors those downlink channel.Each of these downlink channel be when supporting E-DCH, use and can be considered in order to scheduling at the E-DCH of uplink data by MS 10 special uses.Usually, as known in the art, these downlink parameter and the parameter that is used for up link E-DCH are sent to MS 10 in one or more physical channel configuration messages, can change though initially set up the mode of E-DCH.These technology relate to up link E-DCH and being associated and the downlink channel of support uplink E-DCH and the parties concerned of those downlink channel.
Now MS 10 move to the second place 31 ' and after Serving cell changes the 2nd BS212 ' become serving node B, and in Serving cell change process, keep the E-DCH 36 that is used for MS10 all the time.Serving cell changes and can realize with any multiple mode as known in the art, and can be included in coordination between first node B BS1 12 and the Section Point B BS2 12 '.Instantiation shown in Fig. 4 finds that RNC 14 discharges first node B BS1 12 used E-AGCH and is that Section Point B BS2 12 ' disposes new E-AGCH that this can be used for experiencing when the Serving cell of a BS1 12 to the 2nd BS2 12 ' changes at same MS 10 is that same MS changes E-AGCH.Particularly, SRNC 14 sends request 38 that discharges E-AGCH and the request 38 ' that also sends the new E-AGCH of configuration to Section Point B BS2 12 ' to first node B BS112.Each suitably makes a response 40 these Node B.In one embodiment, request 38,38 ' can be that radio link reconfigures preliminary message, is to have as mentioned the radio link that E-RGCH with reference to the described new introducing of Fig. 2-3 discharges designator to reconfigure ready message and respond 40.Reconfigure at the physical channel that sends to UE and can comprise also in the message that E-RGCH discharges designator or similar cell.Although Fig. 4 illustrates release E-AGCH in a sub-district and dispose new E-AGCH in another sub-district, but also can with BS 12,12 ' and MS 10 between similar signaling reconfigure E-RGCH, also notify SRNC 14 in order to discharge, to dispose or reconfigure E-AGCH and/or E-HICH and any change of making in certain embodiments, as shown in concrete among Fig. 5-6.In the prior art, the Section Point B that becomes serving node B will use E-AGCH and the E-RGCH that uses in the Node B of serving before Serving cell changes, do not discharge, change after the EDCH or add any downlink channel in those downlink channel because be provided to set up; Have only by termination E-DCH and just can make a change.The radio resource of supposing to be used for this channel E-RGCH is limited, the E-RNTI that distributes when setting up E-DCH, signature sequence or channelization codes may not be optimum for Section Point B (BS2 12 '), and this Node B can more or less be used the downlink channel of supporting the E-DCH (E-AGCH, E-HICH, E-AGCH) different with first node B (BS1 12).
In order to become E-AGCH, notice MS 10 has discharged an E-AGCH 32 and will use the 2nd E-AGCH 32 ' SRNC 14 in the message such as reconfiguring at physical channel.When receiving that this reconfigures message, MS 10 deletion it previously stored be used for the parameter of an E-AGCH 32 and store arbitrary Node B (BS112, BS2 12 ') of being used for the 2nd E-AGCH 32 ' those receive parameters.Can make similar change to E-RGCH and E-HICH, start by Node B rather than SRNC 14 though those change usually.What the physical channel that sends to MS 10 reconfigured that message can comprise that notice MS 10 discharged previous E-RGCH 34 discharges such field of designator and the new argument that is used for new E-RGCH 34 ' such as E-RGCH shown in Fig. 2-3.Because MS 10 no longer needs the parameter (channelization code and signature sequence) with the E-RGCH 34 of the present release of first node B BS1 12 uses then, so it deletes them from any local storage of storing those parameters.The radio resource that is used for the present E-RGCH 34 that discharges can be redistributed for not using by network (the first node B BS1 of Fig. 4) then.
Under the situation that does not break away from these instructions, two different nodes B 12,12 ' can be under the control of different RNCs.When Serving cell changes when having used that sub-district 12,12 ' is coordinated this soft technique mutually before reality changes the control of MS 10, as above concrete described signaling can be finished by serving node B BS1 12, serving node B BS2 12 ' or by their a certain combination, make when Serving cell changes or before control is transmitted or take place soon afterwards to E-RGCH final release, dispose or reconfigure.These identical process are equally applicable to reconfigure E-HICH, wherein MS 10 goes up the automatic repetitive requests that sends it and the former E-HICH 37 that sets up with E-DCH 36 is released at the E-HICH that reconfigures 37 ', makes first node B BS1 12 can use those radio resources that discharge now for not using.
Fig. 5 illustrates the procedure chart of the various example embodiment of the present invention.As mentioned above, there is Node B to become the example of non-serving node B from serving node B.As the starting position originally of piece 502, suppose that MS 10 becomes under the control of serving node B of non-serving node B after Serving cell changes.E-DCH is at least E-AGCH and E-HICH supports; Hereinafter specifically describe the alternate examples of E-RGCH.Starting Serving cells at piece 504 when serving node B is received the request that (from SRNC's) change for Serving cell changes.For the situation that disposes E-RGCH (506), serving node B can be adjudicated the current configuration constant (512) that discharges E-RGCH (508), reconfigures E-RGCH (510) (shared such as being reconfigured as from special use) or keep E-RGCH.For the situation 514 that does not dispose E-RGCH before changing at Serving cell, serving node B can be adjudicated current configuration constant (512) or the configuration E-RGCH (516) that keeps E-RGCH.518 notice SRNC 14 should adjudicate at piece, carried out Serving cell then and changed, and wherein serving node B described in Fig. 5 becomes non-serving node B.
Fig. 6 illustrates the process steps according to illustrated embodiments of the invention, wherein discharges or reconfigures the downlink channel E-RGCH (perhaps keep it constant) of support uplink E-DCH and be that MS 10 keeps E-DCH.Fig. 6 is the additional figure of Fig. 5, because Fig. 6 illustrates the contingent step in non-serving node B place that becomes serving node B after Serving cell changes.As the starting point originally of Fig. 6, piece 602 shows non-serving node B and support MS 10 (user equipment (UE)) on the up link E-DCH with down link E-HICH.At certain a bit, non-serving node B receives the request 604 of the serving node B that becomes UE from SRNC.For the situation 606 that before Serving cell changes, has disposed E-RGCH, the current configuration constant (612) that non-serving node B can be adjudicated and discharged E-RGCH 608, reconfigures E-RGCH (such as being reconfigured as special use from public) or be kept E-RGCH.For the situation 614 that does not dispose E-RGCH before changing at Serving cell, non-serving node B can be adjudicated the current configuration constant 612 that keeps E-RGCH or be disposed new E-RGCH 616.618 notice SRNC 14 should adjudicate at piece, carried out Serving cell then and changed, and wherein non-serving node B becomes serving node B then described in Fig. 6.
