Description
Technical field
The present invention relates to field of mobile communication, TD SDMA (Time DivisionSynchronization Code Division Multiple Access particularly, TD-SCDMA) in the system, a kind of implementation method of supporting HS-DSCH (high speed descending sharing channel) resource distribution and dynamic adjustment at multi-carrier district.
Background technology
HSDPA (high speed downlink packet access) technology is a kind of technology that the high-speed down data business is provided at the multi-user.The business that is suitable for a large amount of download messages such as multimedia, Internet.
HSDPA has introduced a kind of new transmission channel: HS-DSCH (high speed descending sharing channel), makes the user share descending sign indicating number resource and power resource, carries out time division multiplexing.This structure is applicable to sudden Packet data service.
Down physical channel HS-SCCH (High-Speed Shared Control Channel) is used to carry the physical layer that is used on the HS-DSCH decoding and controls signaling.By reading the information on the HS-SCCH, UE (subscriber equipment) can find HS-DSCH resource into this UE configuration according to physical layer information such as the code channel of its appointment, time slot, modulation systems.
According to the 3GPP agreement, in TD-SCDMA (TD SDMA) system, a cell configuration is on a carrier frequency, the collocation method of HS-DSCH resource is: 1 HS-DSCH, many HS-SCCH are with each HS-SCCH uplink physical channel HS-SICH (high-speed shared information channel) one to one.
When network side is UE configuration HS-DSCH resource, dispose 1～4 HS-SCCH, constitute 1 HS-SCCH collection, and dispose and each HS-SCCH HS-SICH one to one.UE obtains the configuration information of HS-DSCH by reading the signaling message that HS-SCCH goes up carrying.This HS-SCCH collection of UE continuous monitoring.At each TTI (transmission time interval), UE possible configuration 1 HS-SCCH wherein.In case UE finds that HS-SCCH that is configured to use, UE only monitors this HS-SCCH from next TTI.
According to the 3GPP agreement, search for each HS-SCCH of the HS-SCCH collection that is assigned with successively as UE, compare with the UE sign of oneself by " UE sign " information that reads on the HS-SCCH, therefrom find by actual disposition to behind that HS-SCCH of oneself, because only may be configured 1 HS-SCCH at 1 TTI, UE no longer monitors the HS-SCCH of other distribution.UE monitors this HS-SCCH always, use the signaling information of its carrying to obtain the dynamic parameter configuration of HS-DSCH, up at certain TTI, UE can not read the UE sign that conforms to oneself at this HS-SCCH, maybe can not read this HS-SCCH, then UE monitors this HS-SCCH collection that is assigned with again, up to finding 1 HS-SCCH that conforms to UE sign own.
At the TD-SCDMA multi-carrier frequency system, when network and UE are supported on a plurality of carrier waves when disposing the HS-DSCH resource simultaneously for this UE, network side is according to the ability of UE, the business of UE and the factors such as resource of network side, can on one or more carrier waves, be this UE configuration HS-DSCH, the down control channel HS-SCCH of these HS-DSCH is configured on 1 carrier wave simultaneously, and this carrier wave is exactly the carrier wave of DPCH (DPCH) channel of carrying UE high-level signaling.Network side is UE, at the HS-DSCH on each carrier wave, all distributed 1～4 HS-SCCH, when carrier frequency number is 6, network side can distribute 24 HS-SCCH for UE at most in theory, when actual allocated, when network side is UE when disposing the HS-DSCH resource of a plurality of frequencies, network side is that the HS-SCCH number that UE distributes only need be just passable more than carrier frequency number.
Because all HS-SCCH of HS-SCCH collection are carried on the carrier frequency, and the HS-DSCH of its indication is configured on the different carrier frequency, therefore, not only need information such as channel code, time slot on the HS-SCCH, also need to replenish frequency point information, what indicate this HS-SCCH control is HS-DSCH resource on which carrier wave.In a word, HS-SCCH need comprise: carrier frequency, code channel, time slot and other physical layer information.
In single carrier cell, network side can dynamically be adjusted the HS-DSCH resource by the HS-DSCH configuration information of HS-SCCH carrying, and particularly, network side is dynamically adjusted HS-SCCH and gone up code channel number and the number of time slot that the signaling of carrying is adjusted HS-DSCH; In the multi-carrier frequency system of supporting HSDPA, network side can be UE configuration HS-DSCH resource on a plurality of carrier frequency, just with respect to single carrier cell, network side is except the code channel number and number of time slot of adjusting HS-DSCH, can also can dynamic assignment HS-DSCH resource by adjusting that frequency point information (as: increase or delete certain carrier wave) comes, network side is realized this function by the carrier frequency unit on the dynamic-configuration HS-SCCH.
In single carrier cell, distribute to oneself HS-SCCH collection at network side, UE in a single day search 1 with HS-SCCH that the UE sign of oneself conforms to after, just do not need to search for again other HS-SCCH.And in multi-carrier frequency cell, network side is that UE has disposed the HS-DSCH resource on one or more carrier frequency, so network side is a plurality of HS-SCCH that HS-SCCH collection that UE distributes comprises corresponding these carrier frequency.UE search one with HS-SCCH that the UE sign of oneself conforms to after, also need to continue to search for other HS-SCCH that HS-SCCH concentrates, to find on which carrier frequency, all the having disposed HS-DSCH resource.A plurality of HS-SCCH that these conform to the UE sign of oneself, the HS-DSCH of the corresponding different frequent points of difference, these HS-SCCH have constituted the HS-SCCH active set at this UE, and UE only monitors the HS-SCCH in this HS-SCCH active set subsequently.
Yet, according to present agreement, although network side can be by adjusting the parameter of HS-SCCH, support the dynamic adjustment of HS-DSCH in the single-carrier cell, but be not supported in multi-carrier district, by the HS-DSCH resource that increases or delete one or more frequencies to realize the dynamic adjustment of HS-DSCH resource.
Simultaneously, according to present agreement, in single-carrier cell, network side is that a UE has distributed 1～4 HS-SCCH, UE searches for these HS-SCCH continuously, and up to searching a HS-SCCH who conforms to the UE sign of oneself, UE no longer searches for other HS-SCCH then, and, only monitor this HS-SCCH from next TTI.Yet, at multi-carrier district, network side need dispose a plurality of HS-SCCH that conform to the UE sign for UE in order to carry the configuration information of HS-DSCH on a plurality of carrier waves, which so UE need search for all HS-SCCH that HS-SCCH concentrates, conform to the UE sign of oneself to determine HS-SCCH.As seen, present agreement does not have the method for a plurality of HS-SCCH that conform to the UE sign of oneself of clear and definite UE search, that is to say, does not indicate UE and when finishes to search for HS-SCCH and when begin to search for again HS-SCCH.

Embodiment
When network side is that the HS-SCCH collection that UE distributes resides in a carrier frequency (that is: the carrier frequency of the DPCH of carrying UE) when going up, in order to realize the ability of a plurality of HS-SCCH that conform to the UE sign of oneself of UE search, method provided by the invention, its total inventive concept is to make up frequency search indication information unit in HS-SCCH loaded information unit, to add frequency search indication information.
Like this, the HS-DSCH configuration information that carries on HS-SCCH except frequency point information, code channel, time slot and other physical layer parameter, has also added frequency search indication information.This frequency search indication information is used to indicate UE when to begin search and finishes search HS-SCCH, maybe with the HS-SCCH number information notification UE that disposes.
Wherein, search HS-SCCH is meant the HS-SCCH that UE concentrates search to conform to the UE sign of oneself from the HS-SCCH that distributes;
The HS-SCCH number is meant the number of UE from the concentrated HS-SCCH that conforms to the UE sign of oneself that search of the HS-SCCH that distributes, and these HS-SCCH constitute the HS-SCCH active set.
In addition, under general plotting of the present invention, clearly, this frequency search indication information can be added on separately in the HS-SCCH loaded information, also can encode together with frequency point information, can constitute " frequency search indication information unit ".
If adopt the mode of adding separately, then HS-SCCH went up loaded information and comprised: carrier frequency information, frequency search indication information, code channel, time slot and other physical layer parameter etc. this moment.
The content of the frequency search indication information that is added can be to be used to indicate begin to search for the byte of HS-SCCH and the byte that is used to finish to search for HS-SCCH; It also can be the byte that is used to indicate the HS-SCCH number.
If frequency search indication information, constitutes one " frequency search indication information unit " with frequency point information (coding), then should " frequency search indication information unit " comprise: frequency point information, or beginning search information/end search information.Wherein can arrange, for example: when the parameter value of frequency search indication information is some particular value, no longer represent frequency point information, and expression begins to search for HS-SCCH and finishes search HS-SCCH respectively the parameter configuration of frequency point information;
When HS-SCCH the frequency of frequency and HS-SCCH itself of corresponding HS-DSCH when identical, the parameter value of frequency search indication information adopts particular value, expression begins search or finishes search information;
When HS-SCCH the frequency of corresponding HS-DSCH and HS-SCCH itself frequency not simultaneously, the parameter value of frequency search indication information is represented the frequency point information of HS-DSCH.
Owing on the resident frequency of HS-SCCH itself, must dispose the HS-DSCH resource, therefore, the HS-SCCH for this HS-DSCH configuration signal can be called main HS-SCCH.Only the search of the frequency on main HS-SCCH indication information just allows and the necessary particular value that uses, and expression begins search or finish to search for.
Further, for the sub-district that has disposed for example maximum 6 carrier wave HS-DSCH, frequency search indication information can be represented with 3 bits; Main HS-SCCH goes up frequency search indication information and represents to begin search or finish search HS-SCCH, uses particular value: 000 and 111; Other HS-SCCH that UE is configured goes up the frequency point information that frequency search indication information is represented corresponding HS-DSCH, represents frequency numbering 1～6 with 001～110.
The last loaded information of HS-SCCH this moment then comprises: frequency search indication information, code channel, time slot and other physical layer parameter etc.

(step 203) subscriber equipment is concentrated search high-speed share control channels successively at the High-Speed Shared Control Channel that distributes, and determines effective High-Speed Shared Control Channel;
When (step 204) equals " high speed shared control channel amount " in the described frequency search indication information that carries when the quantity of effective High-Speed Shared Control Channel that subscriber equipment is determined on High-Speed Shared Control Channel, other High-Speed Shared Control Channels that the High-Speed Shared Control Channel that stops search is concentrated;
(step 205) constitutes active set with described definite effective High-Speed Shared Control Channel, and subscriber equipment is only monitored the High-Speed Shared Control Channel in this active set.
Further, can also comprise the steps (not shown):
When (step 206) was not equal to the quantity of the High-Speed Shared Control Channel in the described High-Speed Shared Control Channel active set when " high speed shared control channel amount " in the frequency search indication information that user equipment monitors is carried to High-Speed Shared Control Channel, subscriber equipment began search high-speed share control channels again from step 203.
According to said method, UE concentrates at the HS-SCCH that distributes and searches for HS-SCCH successively, number as the HS-SCCH that conforms to the UE sign of oneself that finds, when equaling " the HS-SCCH number " in " the frequency search indication " information on the HS-SCCH, UE other HS-SCCH that HS-SCCH concentrates that stops search, these HS-SCCH constitute the HS-SCCH active set, and each HS-SCCH of this active set indicates the HS-DSCH configuration information of different carrier frequency; Subsequently, UE only monitors all HS-SCCH of this HS-SCCH active set.
When UE monitors " HS-SCCH number " in " frequency search indication " information on the HS-SCCH when being not equal to HS-SCCH number in the HS-SCCH active set, UE restarts to search for HS-SCCH.
As shown in Figure 3, be the frequency search indication information unit of encoding that in HS-SCCH loaded information unit, adds of the present invention with frequency point information, method flow schematic diagram with control user equipment searches High-Speed Shared Control Channel in multi-carrier district comprises the steps:
(step 301) makes up frequency search indication information unit in High-Speed Shared Control Channel loaded information unit;
(step 302) network side is distributed to subscriber equipment with the High-Speed Shared Control Channel collection, and whether the frequency that detects the pairing high speed descending sharing channel of each High-Speed Shared Control Channel is identical with the frequency of itself, if it is identical, then this High-Speed Shared Control Channel is made as the master control channel, frequency of carrying search indication information is set to the information that expression " begins search " on it; If different, then the frequency search indication information of this High-Speed Shared Control Channel carrying is set to represent the frequency point information of its pairing high speed descending sharing channel;
(step 303) subscriber equipment is concentrated at the High-Speed Shared Control Channel that distributes and is searched for all High-Speed Shared Control Channels successively, with definite effective High-Speed Shared Control Channel, and constitutes active set;
(step 304) subscriber equipment feeds back to network side with described definite effective high speed shared control channel signal by its corresponding uplink physical channel;
(step 305) network side is by the quantity of the uplink physical channel of the described carrying feedback information of identification, after determining that itself and actual disposition equate for the high speed shared control channel amount of subscriber equipment, the frequency search indication information that carries on the described main High-Speed Shared Control Channel is set to the information of expression " stopping search ";
(step 306) subscriber equipment High-Speed Shared Control Channel that stops search, and only monitor High-Speed Shared Control Channel in the described definite active set.
Further, can also comprise the steps (not shown):
(step 307) when network side be subscriber equipment when increasing new frequency or deleting the high speed descending sharing channel resource of original frequency, the frequency search indication information that carries on the described main High-Speed Shared Control Channel is set to the information that expression " begins search ";
(step 308) subscriber equipment begins search high-speed share control channels again with described step 303.
For example, as shown in Figure 4, for network side is the HS-DSCH that UE disposes a plurality of frequencies, the HS-SCCH collection is distributed in a principle schematic on the carrier frequency.Be provided with a multi-carrier district, disposed 6 carrier frequency (establish carrier wave f1 and be numbered 1, carrier wave f2 is numbered 2 ... carrier wave f6 is numbered 6), 3 carrier frequency are wherein arranged, and (f1, f2 have disposed the HS-DSCH resource on f6).Certain UE possesses the ability of supporting 6 carrier waves.The frequency of the DPCH of this UE is f1, and then the HS-SCCH collection also resides in f1.
The last frequency search of HS-SCCH indication information represents that with 3 bits 000 expression of specific bit value " begins search " and 111 expressions " finish search "; Bit value 001～110 is represented carrier index 1～6 respectively.
During UE initial ranging HS-SCCH, UE concentrates all HS-SCCH of search at the HS-SCCH that distributes, find one or more HS-SCCH that conform to the UE sign of oneself, constitute the HS-SCCH active set, each HS-SCCH of this active set indicates the HS-DSCH configuration information of different carrier frequency.Obviously, must have the HS-DSCH of 1 HS-SCCH correspondence to be configured on the frequency identical with HS-SCCH itself in the HS-SCCH active set, this HS-SCCH is main HS-SCCH, and its " frequency search indication " information is " 000 " (" beginning search ") particular value.

HS-SCCH1:010 (frequency of corresponding HS-DSCH is f2);
HS-SCCH2:110 (frequency of corresponding HS-DSCH is f6).
When UE monitors one or more HS-SCCH of configuration, and after receiving data on the HS-DSCH of this HS-SCCH configuration, feed back to network side by corresponding 1 or many up signalings (HS-SICH).
The HS-SICH number that recognizes UE feedback when network side equals to dispose the HS-SCCH number to UE, the frequency search indication information that network is gone up main HS-SCCH carrying subsequently is made as " 111 " (" finishing search "), subsequently, UE only monitors all HS-SCCH of this HS-SCCH active set.
At this moment, the parameter value of frequency search indication information unit is:
Main HS-SCCH:111 (frequency of corresponding HS-DSCH is f1, finishes search);
HS-SCCH1:010 (frequency of corresponding HS-DSCH is f2);
HS-SCCH2:110 (frequency of corresponding HS-DSCH is f6).
When network side was the HS-DSCH resource of new frequency f3 of UE increase and f4, the frequency search indication information of main HS-SCCH being gone up carrying was made as " 000 ", and then UE restarts to search for HS-SCCH.
At this moment, the parameter value of the frequency of search search indication information unit is again:
Main HS-SCCH:000 (frequency of corresponding HS-DSCH is f1, begins search);
HS-SCCH1:010 (frequency of corresponding HS-DSCH is f2);
HS-SCCH1:011 (frequency of corresponding HS-DSCH is f3);
HS-SCCH1:100 (frequency of corresponding HS-DSCH is f4);
HS-SCCH2:110 (frequency of corresponding HS-DSCH is f6).
The parameter value of the frequency search indication information unit after search finishes is:
Main HS-SCCH:111 (frequency of corresponding HS-DSCH is f1, finishes search);
HS-SCCH1:010 (frequency of corresponding HS-DSCH is f2);
HS-SCCH1:011 (frequency of corresponding HS-DSCH is f3);
HS-SCCH1:100 (frequency of corresponding HS-DSCH is f4);
HS-SCCH2:110 (frequency of corresponding HS-DSCH is f6).
