Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Fig. 1 is the flow chart of method of the sky line options of one embodiment of the invention.The method of Fig. 1 is carried out by base station (for example NodeB).
101, send directive command (order) by the first channel to subscriber equipment, directive command is used to indicate subscriber equipment and monitors second channel to obtain AS pattern indication information.
Alternatively, in one embodiment, above-mentioned the first channel is HS-SCCH, and second channel is F-PCICH.F-PCICH is the indication information when being used for transmitting up CLTD specially, is used at present transmitting PCI under the BF pattern.The embodiment of the invention is still used this transmission AS pattern indication information under the AS pattern.
102, send AS pattern indication information by second channel to described subscriber equipment, so that described subscriber equipment is determined employed AS pattern according to AS pattern indication information, wherein employed AS pattern comprises an AS pattern or the 2nd AS pattern.
For example, an AS pattern and the 2nd AS pattern can correspond respectively to the configuration 2 and 3 in the above-mentioned table 1.Particularly, under an AS pattern, subscriber equipment uses the first antenna (for example, the physical antenna in the table 1 1) transmission all uplink physical channels except S-DPCCH, and use the second antenna (for example, the physical antenna in the table 1 2) to send S-DPCCH.Under the 2nd AS pattern, subscriber equipment uses the first antenna to send S-DPCCH, and uses the second antenna transmission all uplink physical channels except S-DPCCH.The embodiment of the invention is not limited to this example, and the send mode that for example an AS pattern and the 2nd AS pattern can be referred to exchanges.
The embodiment of the invention only needs a directive command order indicating user on the first channel to enter the AS pattern, and indicates any AS pattern of concrete use by second channel to the user, thereby can save the order resource.
Alternatively, as an embodiment, the base station can send AS pattern indication information by second channel according to the period 1 (hereinafter being called ACI_Update_cycle), and one of them AS pattern indication information is by at least one the time slot carrying on the second channel.For example, can be in 1,2,3 or more time slot AS pattern indication information of carrying, the number M that namely carries at least one time slot of an AS pattern indication information is positive integer.
As nonrestrictive example, for example, when in 1 time slot, sending AS pattern indication information, can use " 0 " expression the one AS pattern, " 1 " expression the 2nd AS pattern, vice versa.When in 2 time slots, sending AS pattern indication information, can use " 00 " expression the one AS pattern, " 11 " expression the 2nd AS pattern, vice versa.When in 3 time slots, sending AS pattern indication information, can use " 000 " expression the one AS pattern, " 111 " expression the 2nd AS pattern, vice versa.
When using a plurality of time slots to send AS pattern indication information, can be to use a continuous N time slot combined coding, also can use a discontinuous M time slot.Receiving-transmitting sides obtains the call number of time slot or time slot according to identical rule.
Alternatively, as an embodiment, suppose ACI_Update_cycle=15slots, use continuous 3 time slots to send AS pattern indication information.Because 1slot is corresponding to 2/3ms, so the base station sends one time 000 or 111 every 10ms, UE uses corresponding AS pattern with indication.
Alternatively, as another embodiment, in the situation of using a N continuous AS pattern indication information of time slot carrying, can obtain based on the Connection Frame Number (CFN, Connection Frame Number) of period 1 ACI_Update_cycle and second channel the call number of initial time slot in above-mentioned at least one time slot.Period 1 ACI_Update_cycle can be the integral multiple of TTI (Transmission Time Interval, Transmission Time Interval) or non-integral multiple.For example, when period 1 ACI_Update_cycle is the integral multiple of TTI, can be according to number M and the shared side-play amount N of bit in a time slot of AS pattern indication information of at least one time slot that carries an AS pattern indication information
Off1, based on the Connection Frame Number CFN of period 1 ACI_Update_cycle and second channel, obtain the call number of above-mentioned at least one time slot.
For example, can obtain according to following formula the call number of initial time slot, then in the continuous N time slot that the call number of resulting initial time slot begins, send a described AS pattern indication information.
If ACI_Update_cycle is the integral multiple of TTI, then:
When AS was carried on 1 slot upper (M=1), the call number of initial time slot can obtain according to following formula (1) or (2)
(15 * CFN+i) mod ACI_Update_cycle=0 N
Off1=0 or 2 (1)
(15 * CFN+i+1) mod ACI_Update_cycle=0 N
Off1Greater than 2 (2)
When AS was carried on 2 slot (M=2), the call number of initial time slot can obtain according to following formula (3) or (4)
(15 * CFN+i+1) mod ACI_Update_cycle=0 N
Off1=0 or 2 (3)
(15 * CFN+i+2) mod ACI_Update_cycle=0 N
Off1Greater than 2 (4)
When AS was carried on 3 slot (M=3), the call number of initial time slot can obtain according to following formula (5) or (6)
(15 * CFN+i+2) mod ACI_Update_cycle=0N
Off1=0 or 2 (5)
(15 * CFN+i) mod ACI_Update_cycle=0 N
Off1Greater than 2 (6)
Wherein, mod is modulo operation.N
Off1Be when the AS pattern, to represent the side-play amount of the shared bit of AS pattern indication information in a time slot, can be determined by the time slot format (slot format) of F-PCICH channel.I is the call number of initial time slot in above-mentioned at least one time slot of an AS pattern of the carrying indication information on the F-PCICH channel.CFN is Connection Frame Number, can be determined by the frame shifting amount of SFN (System Frame Number, System Frame Number) and F-PCICH.
Here, if ACI_Update_cycle is the integral multiple of TTI, can guarantee that then UE changes the AS pattern at the subframe boundary.For example, if in up link, want compatible MIMO (Multiple Input Multiple Output, multiple-input and multiple-output) pattern, consideration is in the single double-current handoff scenario of MIMO, and base station or network side need the performance of a data block of complete statistics and determine whether to carry out a day line options operation.Because E-DPDCH is (E-DCH Dedicated Physical Data Channel, the E-DCH Dedicated Physical Data Channel) be that each 2ms TTI is that unit sends, so by the embodiment of the invention can make subscriber equipment in the single double-current handoff scenario of MIMO in the 2ms TTI data block pre-coding matrix of experience weighting identical, be that the interior signal to noise ratio of 2ms TTI data block is identical, conveniently carry out a day line options operation.
On the other hand, when ACI_Update_cycle was TTI non-integral multiple, the call number of time slot can obtain according to following formula (7)
(15×CFN+i)mod ACI_Update_cycle＝0 (7)
Therefore, the embodiment of the invention only needs a directive command order indicating user on the first channel to enter the AS pattern, and indicates any AS pattern of concrete use by second channel to the user, thereby can save an order resource.
In addition, in the prior art, if subscriber equipment switches on the single-shot pattern (configuration 4 and 5 in the table 1), an antenna is deactivated, then subscriber equipment can not send S-DPCCH, activates unless re-start CLTD, otherwise can't switch back CLTD BF pattern fast.If avoid entering the single-shot pattern, CLTD AS pattern (because S-DPCCH still sends, so can switch back fast CLTD BF pattern) preferably exists as normality so.But it is oversize to activate 2 CLTD AS pattern entry-into-force times with order, is not suitable for the CLTD AS pattern of normality.
In the prior art, activate or deexcitation CLTD isotype with order, the F-PCICH resource that disposes so to the user does not discharge (because these operations are that do the base station, other network elements of network side may not known).In the case, even UE switches to the single-shot pattern, the F-PCICH that this UE disposes when the CLTD pattern still exists, and has so just caused the waste on the resource.The embodiment of the invention can also be configured by CLTD pattern or the single-shot pattern of base station controller to activation or deexcitation subscriber equipment, for example by RNC (Radio Network Controller, radio network controller) allocation activation CLTD pattern and single-shot pattern, base station and/or subscriber equipment receive the configuration of RNC.The waste on this resource can be avoided like this, namely when the RNC configuration UE is the single-shot pattern, the F-PCICH resource of this UE special use can be discharged.
Can indicate the employed AS pattern of UE by F-PCICH in the embodiment of the invention, speed, and do not need order to activate, the order resource can be saved, and the normality of AS pattern can be realized.In addition, if AS exists as normality, the order (configuration 4 and 5 in the top table 1) that indication enters the single-shot pattern also can save, and can further save the order resource.
Fig. 2 is the flow chart of method of the sky line options of another embodiment of the present invention.The method of Fig. 2 is carried out by subscriber equipment (for example UE), and corresponding with the method for Fig. 1, therefore suitably omits and describes in detail.
201, receive directive command by the first channel from the base station.
For example, above-mentioned the first channel can be HS-SCCH.
202, according to above-mentioned directive command, monitor the AS pattern indication information that second channel sends at second channel to obtain the base station.
Alternatively, in one embodiment, above-mentioned second channel is F-PCICH.F-PCICH is the indication information when being used for transmitting up CLTD specially, is used at present transmitting PCI under the BF pattern.The embodiment of the invention is still used this transmission AS pattern indication information under the AS pattern.
203, determine employed AS pattern according to AS pattern indication information, wherein employed AS pattern comprises an AS pattern or the 2nd AS pattern.
For example, an AS pattern and the 2nd AS pattern can correspond respectively to the configuration 2 and 3 in the above-mentioned table 1.Particularly, under an AS pattern, subscriber equipment uses the first antenna (for example, the physical antenna in the table 1 1) transmission all uplink physical channels except S-DPCCH, and use the second antenna (for example, the physical antenna in the table 1 2) to send S-DPCCH.Under the 2nd AS pattern, subscriber equipment uses the first antenna to send S-DPCCH, and uses the second antenna transmission all uplink physical channels except S-DPCCH.The embodiment of the invention is not limited to this example, and the send mode that for example an AS pattern and the 2nd AS pattern can be referred to exchanges.
The embodiment of the invention only needs a directive command order indicating user on the first channel to enter the AS pattern, and indicates any AS pattern of concrete use by second channel to the user, thereby can save the order resource.
Alternatively, as an embodiment, in step 202, subscriber equipment can be according to period 1 ACI_Update_cycle, the AS pattern indication information that reception sends by second channel, one of them AS pattern indication information is by at least one the time slot carrying on the second channel.For example, may be received in AS pattern indication information of carrying in 1,2 or 3 time slots, the number M that namely carries at least one time slot of an AS pattern indication information is positive integer.
Alternatively, when using a plurality of time slots to send AS pattern indication information, can be to use a continuous N time slot combined coding, also can use a discontinuous M time slot.Receiving-transmitting sides obtains the call number of time slot or time slot according to identical rule.
Subscriber equipment can obtain according to the identical rule of base station side the call number of time slot call number or initial time slot.For example, subscriber equipment can according to top formula (1)-(7), based on the Connection Frame Number CFN of period 1 ACI_Update_cycle and second channel, obtain the call number of the initial time slot of at least one time slot.Be in the situation of integral multiple of TTI at period 1 ACI_Update_cycle, according to number M and the shared side-play amount N of bit in a time slot of AS pattern indication information of at least one time slot of an AS pattern indication information of carrying
Off1, based on the Connection Frame Number CFN of period 1 ACI_Update_cycle and second channel, obtain the call number of the initial time slot of at least one time slot.If ACI_Update_cycle is the integral multiple of TTI, can guarantee that then UE changes the AS pattern at the subframe boundary, conveniently carry out a day line options operation.
Fig. 3 is the flow chart of the antenna selection course of another embodiment of the present invention.In the embodiments of figure 3, UE representative of consumer equipment, NodeB represents the base station.
301, after UL CLTD used, when certain root antenna of UE was in poor-performing for a long time, NodeB sent directive command order by HS-SCCH to UE, prepared to adopt the AS pattern with indication UE.
After the order that 302, UE sends, send acknowledge message to NodeB in receiving step 301.This acknowledge message can be ACK (affirmation) or NACK (negative acknowledgement).What suppose in step 302 to send is ACK message.
303,12 or 18 time slots after NodeB receives the ACK message of UE, order comes into force.After this NodeB begins according to period 1 ACI_Update_cycle, sends AS pattern indication information to UE in the F-PCICH channel.Before order came into force, NodeB still sent the indication information of BF in the F-PCICH channel.
304, UE monitors F-PCICH, obtains the AS pattern indication information that NodeB sends at F-PCICH.Described in the mode of transmitting-receiving AS pattern indication information can see figures.1.and.2, therefore no longer be repeated in this description.
305, UE determines employed AS pattern according to the AS pattern indication information that receives.Employed AS pattern comprises an AS pattern or the 2nd AS pattern.For example, under an AS pattern, subscriber equipment uses the first antenna (for example, the physical antenna 1 in the table 1) transmission all uplink physical channels except S-DPCCH, and uses the second antenna (for example, the physical antenna in the table 1 2) to send S-DPCCH.Under the 2nd AS pattern, subscriber equipment uses the first antenna to send S-DPCCH, and uses the second antenna transmission all uplink physical channels except S-DPCCH.The embodiment of the invention is not limited to this example, and the send mode that for example an AS pattern and the 2nd AS pattern can be referred to exchanges.
306, UE sends data according to determined AS pattern to NodeB.Wherein, UE can send pilot frequency information to NodeB by DPCCH and S-DPCCH.Hereinafter, the upper pilot frequency information that sends of DPCCH is called dominant pilot information, the upper pilot frequency information that sends of S-DPCCH is called the frequently information of teaching.
Alternatively, in one embodiment, teaching frequently, information need not continuous transmission.According to sending S-DPCCH second round (hereinafter being designated as UE_SDPCCH_DTX_cycle), this S-DPCCH carries pilot frequency information, and each the transmission continues the 3rd time span (hereinafter being designated as UE_SDPCCH_burst).Teach the frequently interruption transmission of information, can save the UE transmitting power, reduce uplink interference.
307, NodeB monitors the pilot frequency information (being dominant pilot information) that DPCCH sends at DPCCH to obtain UE, monitor S-DPCCH with the pilot frequency information that obtains UE and send at S-DPCCH (namely, teach frequently information), and the dominant pilot information that listens to according to one or many and teach frequently that information determines the employed AS pattern of described subscriber equipment, and generate corresponding AS pattern indication information.
Be interrupted transmission at UE and teach in the situation of frequency information, NodeB can monitor S-DPCCH according to UE_SDPCCH_DTX_cycle second round, and each monitoring continues the 3rd time span UE_SDPCCH_burst.
308, NodeB according to period 1 ACI_Update_cycle, periodically sends AS pattern indication information to UE according to the similar mode of step 304 in the F-PCICH channel, subsequent step and above-mentioned steps 304-307 are similar, therefore repeat no more.
UE changes if find indicated AS pattern after receiving AS pattern indication information, then changes employed AS pattern.If UE receives new directive command order, then order is switched accordingly as indicated.For example, if new order indication switches to the BF pattern, then UE can switch to the BF pattern after this new order comes into force.
Therefore, the embodiment of the invention only needs a directive command order indicating user on the first channel to enter the AS pattern, and indicates any AS pattern of concrete use by second channel to the user, thereby can save the order resource.
Before or after said process, UE and NodeB can receive base station controller to activating or the CLTD pattern of deexcitation subscriber equipment or the configuration of single-shot pattern, so also can save the order resource.
The embodiment of the invention can realize the AS pattern as normality, and F-PCICH is interrupted and sends AS pattern indication information, and the update cycle of AS pattern is shorter than order control.In addition, if under the AS pattern, teach frequently information interruption transmission, then can save the UE transmitting power, reduce uplink interference.
On the other hand, if ACI_Update_cycle is the integral multiple of TTI, can guarantee that then UE changes the AS pattern at the subframe boundary, conveniently carry out a day line options operation.
Among the embodiment of Fig. 3, UE waits for the upper AS pattern indication information that sends of F-PCICH after receiving order, determine employed AS pattern according to this AS pattern indication information.But the embodiment of the invention is not limited to this.UE can at first select an AS pattern (an AS pattern or the 2nd AS pattern) to try out after receiving order, process according to selected AS pattern execution in step 306-308, namely determine according to the major-minor pilot frequency information that UE sends whether the selected AS pattern of UE is suitable by NodeB, and according to determining that the result carries corresponding AS pattern indication information in the corresponding time slot of the F-PCICH that sends next time, whether UE changes the AS pattern with indication.
In a nonrestrictive embodiment, ACI_Update_cycle can be 15 time slots, and UE_SDPCCH_DTX_cycle can be 11 time slots, and UE_SDPCCH_burst is 4 time slots.But the embodiment of the invention is not limited to these numerical examples, but can adjust as required the length of these times.For example, UE_SDPCCH_DTX_cycle is less, the NodeB several times channel situation of can sampling then more, and channel estimating can be more accurate.ACI_Update_cycle is less, and NodeB can multiplely send several times AS pattern indication information, can increase the accuracy of transmission.
