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 and the relative authorization method of using E-RGCH of E-AGCH.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 and perhaps reduce scheduling rates and/or the power that UE sends on E-DCH than previous authorization value (for example authorizing on the E-AGCH or authorizing according to previous order on the E-RGCH).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 divides into groups to make up link have more elasticity to signal error through allowing as Node B is asked with affirmation or NACK, to retransmit to make mistakes.

Consider E-RGCH, service relative grant and non-service relative grant can be arranged on this shared physical channel.The service relative grant of on down link E-RGCH, transmitting 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) " perhaps " 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 " perhaps " DOWN ".A plurality of non-service relative grant can once send to UE (because have a plurality of neighbor cells under the control of the non-serving node B of difference), and only can have a service relative grant to send to UE (from its Serving cell of dispatching like 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 after setting up E-DCH, in Node B, to discharge, to dispose and reconfigure the technology of E-RGCH, promptly require Node B to use same E-RGCH configuration to be released or to be deleted until RL until E-DCH.Anti-speech,, do not dispose E-DCH when setting up 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, be not directed against the gratifying solution of foregoing problems.

Embodiment

The inventor has realized that the above-mentioned suggestion scheduling of in background technology, mentioning implements to change in the Serving cell process and produce following problem afterwards at UE.

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 hope 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 hope 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, under this situation, can not discharge E-RGCH, 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 hoped 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, under this situation, can not dispose E-RGCH, because Node B must be sent " 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, under this situation, can not dispose E-RGCH, 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 hoped release E-RGCH under the sub-district at non-service cell.Yet, under this situation, can not discharge E-RGCH, 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 hope to be reconfigured as " special-purpose E-RGCH " to 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 first and the 3rd problem of preceding text discussion is crucial especially problem.Exemplary embodiment of the present invention is devoted to the other problem that the first and the 3rd problem that solves and preceding text are enumerated.

These and similar problem possibly take place for E-AGCH/HICH in attention, because same channelization code and the E-RNTI that will use E-AGCH in the Serving cell become non-service cell or E-DCH is released until Serving cell.The same channelization code and the signature sequence that use E-HICH are released until E-DCH.Be used for E-AGCH and E-HICH code and signature sequence to reconfigure for the system that implements VoIP through HSUPA be essential because possibly for example expect that 100 UE are in the sub-district and reconfigure the benefit that possibly 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) like term used herein " radio resource ".

Exemplary embodiment of the present invention mainly relates to HSUPA and to the enhancing of the up link DCH (E-DCH) that is used for Packet data service.Exemplary embodiment of the present invention can used as among the 3GPP of non-limitative example the 6th edition.

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 when Serving cell changes, discharging the E-RGCH resource 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 hopes 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 and in Serving cell, discharge E-HICH and the situation that discharges E-AGCH.

SRNC 14 received the request of release from Node B 12 after, SRNC 14 sent the request of release to UE 10.

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 hopes to dispose/reconfigure E-RGCH/E-HICH/E-AGCH.Can note having only through 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 aforementioned exemplary, 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: radio link orchestration is ready again reconfigure response with radio link).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), the example of use E-RGCH release designator IE (being expressed as 100) has been shown in Fig. 2.

Fig. 3 shows E-RGCH and discharges IE/ packet name and the IE type of designator and an example embodiment of quoting.

With reference to the exemplary enforcement of embodiment (B) that is used for when Serving cell changes discharging the E-RGCH resource of preceding text discussion, can be at the new IE that has indicated release E-RGCH to introducing in order to the response message of carrying out the message request that Serving cell changes (RNSAP/NBAP for example: radio link reconfigures and readyly reconfigures response with radio link).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 of embodiment (C) that is used for when Serving cell changes discharging the E-RGCH resource of preceding text discussion, can to introducing in order to the response message of carrying out the message request that Serving cell changes (RNSAP/NBAP for example: radio link reconfigures and readyly reconfigures response with radio link) in order to indicate the new IE of one of following each item:

A. configuration perhaps reconfigures 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 of preceding text discussion, can introduce new IE and hope 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 in the table 9.1.42 of TS25.433 v6.6.0 and 9.1.47, stipulate 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 (again) configuration E-RGCH/HICH when Serving cell changes of preceding text discussion, can use the similar new IE of new IE that is directed against embodiment A and C discussion with preceding text.Can in new IE or in existing E-DCH FDD DL control channel information, carry the configuration parameter of the E-RGCH/HICH that is used to dispose/reconfigure.

The example that is used for the embodiment (B) of (again) configuration E-RGCH/HICH when Serving cell changes about the preceding text discussion is implemented, and can use the similar new IE of new IE that discusses to embodiment D with preceding text.

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 (than as discussed above and at the release of the E-RGCH shown in Fig. 2 and Fig. 3 designator IE).

Fig. 4 illustrates the operation of various nodes in an example embodiment that relates in sketch map.RNC 14 as previously mentioned.Node B is by first base station BS 1 12 (the for example serving node B of MS before Serving cell changes) and second base station BS 2 12 ' (the for example non-serving node B before Serving cell changes).Represent under the situation of different nodes B with BS2 12 ' at two base station BSs 1 12, they can be under perhaps can the control in different RNCs under the control of single RNC (Serving RNC).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, and 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.

, Serving cell sets up dedicated channel E-DCH (possibly before change to a BS1 12) for MS 10 for Fig. 4 hypothesis before changing 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 on E-DCH, use respectively 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.In Fig. 4, also show down link E-HICH37,37 ', 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 with keep watch on those downlink channel.Each of these downlink channel be when supporting E-DCH, use and can be considered in order to scheduling to uplink data by the special-purpose E-DCH of MS 10.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 ' of also sending 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 like preceding text to reconfigure ready message with reference to the radio link that the E-RGCH of the said new introducing of Fig. 2-3 discharges designator 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 in another sub-district, disposes new E-AGCH; But also can use 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 before Serving cell changes, serving, and not set up EDCH release afterwards, change or will add any downlink channel in those downlink channel because be provided at; Have only through 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 when setting up E-DCH, distributes, signature sequence or channelization codes possibly 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 the parameter (channelization code and signature sequence) of the E-RGCH 34 of the present release that MS 10 no longer need use with first node B BS1 12 then, thus it from any local storage deletion of storing those parameters they.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 each other before reality changes the control of MS 10; As above concrete said signaling can or be accomplished by their a certain combination by serving node B BS1 12, serving node B BS2 12 ', make when Serving cell changes or before control is transmitted or after take place soon to E-RGCH final release, dispose perhaps and reconfigure.These identical process are equally applicable to reconfigure E-HICH; Wherein MS 10 goes up the automatic repetitive requests of sending 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 stated, there is Node B to become the instance 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 describes the alternate examples of E-RGCH.When serving node B is received the request that (from SRNC's) change for Serving cell, starting Serving cells at piece 504 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 the current configuration constant (512) that keeps E-RGCH or disposed E-RGCH (516).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 after Serving cell changes, becomes serving node B.As the starting point originally of Fig. 6, piece 602 shows non-serving node B and on the up link E-DCH with down link E-HICH, supports MS 10 (user equipment (UE)).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 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 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.

The action of attention Fig. 5 can be coordinated in the hope of Serving cell change more stably with the action of Fig. 6 mutually, but they are optional.For example, the non-serving node B of Fig. 6 that becomes serving node B can not have E-RGCH and adjudicates the new E-RGCH of configuration.E-RGCH that Serving cell just known after changing no longer needs its previous use can take place, just discharge it then in Fig. 5 serving node B that becomes non-serving node B.Many other such variations are possible, because Fig. 5 and Fig. 6 do not have positive connection, though the action of coordination service Node B in certain embodiments and non-serving node B is in the hope of efficient deployment of nothing delay of radio resource.Like this, be described as when Serving cell changes the release that takes place/dispose/reconfigure to said channel need not with change to the time of the control of UE takes place fully simultaneously, but can before this control break takes place or after be " when Serving cell changes " generation soon and still.
