After up link introduces CLTD, just require to use double antenna to send data in the uplink.NodeB (base station) needs feedback PCI (Precoding Control Indication, precoding control indicates) information to carry out pre-encode operation to subscriber equipment (UE, User Equipment).PCI information is the precoding vector that receiving terminal feeds back to transmitting terminal, with the block length making transmitting terminal maximization existing channel condition support.
Substantially determine at present and used F-PCICH (Fractional Precoding Control Indication Channel in the downlink, part precoding control indicating channel) channel feeds back PCI, and the update cycle of PCI is 3 time slots (slot), BF (BeamForming, velocity of wave is shaping) codebook size is 2 bits (bit).But in each F-PCICH time slot, the bit number of the PCI of transmission is uncertain, and UE must receive 2 bit PCI information could upgrade pre-coding matrix.
When UE introduces two antennas (such as, be called physical antenna 1 and physical antenna 2) after, because hand blocks or other reasons, the data on a certain antenna may be caused very poor for a long time, namely antenna unbalanced (antenna imbalance) is larger.If now still use BF code book to send, CLTD poor-performing will be caused.Proved by emulation, switch or sky line options (AS, Antenna Selection) if now introduce antenna, CLTD transmitting terminal performance can be improved.But directly AS is introduced code book, performance is also bad, needs other to indicate so UE enters AS state.
Be currently suggested the scheme carrying out Dynamic controlling CLTD process with the order (order) of HS-SCCH (Shared Control Channel for High Speed Downlink Shared Channel, the shared control channel of high speed descending sharing channel).Table 1 lists 5 order being used to refer to five kinds of configurations, wherein configures 2 and 3, is used to refer to two kinds of configurations during AS exactly.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the flow chart of the method for the sky line options of one embodiment of the invention.The method of Fig. 1 is performed by base station (such as 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 mode indication information.
Alternatively, in one embodiment, above-mentioned first channel is HS-SCCH, and second channel is F-PCICH.F-PCICH is the indication information be used for specially when transmitting up CLTD, at present for transmitting PCI under BF pattern.The embodiment of the present invention under AS pattern, still with this transmission AS mode indication information.
102, send AS mode indication information by second channel to described subscriber equipment, so that described subscriber equipment determines used AS pattern according to AS mode indication information, wherein used AS pattern comprises an AS pattern or the 2nd AS pattern.
Such as, an AS pattern and the 2nd AS pattern can correspond respectively to the configuration 2 and 3 in above-mentioned table 1.Particularly, under an AS pattern, subscriber equipment uses the first antenna (physical antenna 1 such as, in table 1) to send all uplink physical channels except S-DPCCH, and use the second antenna (physical antenna 2 such as, in table 1) to send S-DPCCH.Under the 2nd AS pattern, subscriber equipment uses the first antenna to send S-DPCCH, and uses the second antenna to send all uplink physical channels except S-DPCCH.The embodiment of the present invention is not limited to this example, and the send mode that such as an AS pattern and the 2nd AS pattern can be referred to exchanges.
The embodiment of the present invention only needs on the first channel directive command order indicating user to enter AS pattern, and indicates any AS pattern of concrete use by second channel to user, thus can save order resource.
Alternatively, as an embodiment, base station according to period 1 (hereinafter referred to ACI_Update_cycle), can send AS mode indication information by second channel, and one of them AS mode indication information is carried by least one time slot on second channel.Such as, can in 1,2,3 or more time slots a carrying AS mode indication information, the number M namely carrying at least one time slot of an AS mode indication information is positive integer.
Such as, as nonrestrictive example, when sending AS mode indication information in 1 time slot, " 0 " can be used to represent an AS pattern, and " 1 " represents the 2nd AS pattern, and vice versa.When sending AS mode indication information in 2 time slots, " 00 " can be used to represent an AS pattern, and " 11 " represent the 2nd AS pattern, and vice versa.When sending AS mode indication information in 3 time slots, " 000 " can be used to represent an AS pattern, and " 111 " represent the 2nd AS pattern, and vice versa.
When using multiple time slot to send AS mode indication information, can be 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 mode indication information.Because 1slot corresponds to 2/3ms, so base station sends one time 000 or 111 every 10ms, use corresponding AS pattern to indicate UE.
Alternatively, as another embodiment, when using a N continuous time slot to carry an AS mode indication information, the call number of starting time slots at least one time slot above-mentioned can be obtained based on the Connection Frame Number (CFN, Connection Frame Number) of period 1 ACI_Update_cycle and second channel.Period 1 ACI_Update_cycle can be the integral multiple or non-integral multiple of TTI (Transmission Time Interval, Transmission Time Interval).Such as, when period 1 ACI_Update_cycle is the integral multiple of TTI, can bit side-play amount N in one time slot shared by the number M of at least one time slot of a carrying AS mode indication information and AS mode indication information
off1, based on the Connection Frame Number CFN of period 1 ACI_Update_cycle and second channel, obtain the call number of at least one time slot above-mentioned.
Such as, the call number of starting time slots can be obtained according to following formula, in the continuous N time slot then started in the call number of obtained starting time slots, send a described AS mode indication information.
If ACI_Update_cycle is the integral multiple of TTI, then:
When AS is carried on (M=1) on 1 slot, the call number of starting time slots 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
off1be greater than 2 (2)
When AS is carried on 2 slot (M=2), the call number of starting time slots 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
off1be greater than 2 (4)
When AS is carried on 3 slot (M=3), the call number of starting time slots 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
off1be greater than 2 (6)
Wherein, mod is modulo operation.N
off1be the bit side-play amount in one time slot represented when AS pattern shared by AS mode indication information, can be determined by the time slot format of F-PCICH channel (slot format).I is the call number of starting time slots at least one time slot above-mentioned of a carrying AS mode indication information on F-PCICH channel.CFN is Connection Frame Number, can be determined by SFN (System Frame Number, System Frame Number) and the frame shifting amount of F-PCICH.
Here, if ACI_Update_cycle is the integral multiple of TTI, then can ensure that UE changes AS pattern at sub-frame boundary.Such as, if want compatible MIMO (Multiple Input Multiple Output in the uplink, multiple-input and multiple-output) pattern, consider in the mono-double-current handoff scenario of MIMO, base station or network side need the performance of a complete statistics data block and determine whether carry out antenna selection operation.Because E-DPDCH is (E-DCH Dedicated Physical Data Channel, E-DCH Dedicated Physical Data Channel) to be each 2ms TTI be, and unit sends, so it is identical subscriber equipment can be made in the mono-double-current handoff scenario of MIMO to experience the pre-coding matrix of weighting in 2ms TTI data block by the embodiment of the present invention, namely the signal to noise ratio in 2ms TTI data block is identical, conveniently carries out antenna selection operation.
On the other hand, when ACI_Update_cycle is 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 present invention only needs on the first channel directive command order indicating user to enter AS pattern, and indicates any AS pattern of concrete use by second channel to user, thus can save an order resource.
In addition, in prior art, if subscriber equipment is switched on single shot mode (configuration 4 and 5 in table 1), an antenna is deactivated, then subscriber equipment can not send S-DPCCH, activates, otherwise cannot switch back CLTD BF pattern fast unless re-started CLTD.If avoid entering single shot mode, so CLTD AS pattern (because S-DPCCH still sends, so can switch back CLTD BF pattern fast) preferably exists as normality.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 prior art, activate with order or deexcitation CLTD isotype, so configure and do not discharge (because these operations are that base station is done, other network elements of network side may not known) to the F-PCICH resource of user.In the case, even if UE is switched to single shot mode, the F-PCICH that this UE configures when CLTD pattern still exists, and so just causes the waste in resource.The embodiment of the present invention can also by base station controller to activate or the CLTD pattern of deexcitation subscriber equipment or single shot mode are configured, such as by RNC (Radio Network Controller, radio network controller) allocation activation CLTD pattern and single shot mode, base station and/or subscriber equipment receive the configuration of RNC.The waste in this resource can be avoided like this, namely when RNC configuration UE is single shot mode, the F-PCICH resource that this UE is special can be discharged.
By the AS pattern that F-PCICH indicates UE to use in the embodiment of the present invention, speed, and do not need order to activate, 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 above in table 1) that instruction enters single shot mode also can save, and can save order resource further.
Fig. 2 is the flow chart of the method for the sky line options of another embodiment of the present invention.The method of Fig. 2 is performed by subscriber equipment (such as UE), and corresponding with the method for Fig. 1, therefore suitably omits detailed description.
201, receive directive command by the first channel from base station.
Such as, above-mentioned first channel can be HS-SCCH.
202, according to above-mentioned directive command, monitor the AS mode indication information that second channel sends on a second channel to obtain base station.
Alternatively, in one embodiment, above-mentioned second channel is F-PCICH.F-PCICH is the indication information be used for specially when transmitting up CLTD, at present for transmitting PCI under BF pattern.The embodiment of the present invention under AS pattern, still with this transmission AS mode indication information.
203, determine used AS pattern according to AS mode indication information, wherein used AS pattern comprises an AS pattern or the 2nd AS pattern.
Such as, an AS pattern and the 2nd AS pattern can correspond respectively to the configuration 2 and 3 in above-mentioned table 1.Particularly, under an AS pattern, subscriber equipment uses the first antenna (physical antenna 1 such as, in table 1) to send all uplink physical channels except S-DPCCH, and use the second antenna (physical antenna 2 such as, in table 1) to send S-DPCCH.Under the 2nd AS pattern, subscriber equipment uses the first antenna to send S-DPCCH, and uses the second antenna to send all uplink physical channels except S-DPCCH.The embodiment of the present invention is not limited to this example, and the send mode that such as an AS pattern and the 2nd AS pattern can be referred to exchanges.
The embodiment of the present invention only needs on the first channel directive command order indicating user to enter AS pattern, and indicates any AS pattern of concrete use by second channel to user, thus can save order resource.
Alternatively, as an embodiment, in step 202., subscriber equipment can according to period 1 ACI_Update_cycle, receive the AS mode indication information sent by second channel, one of them AS mode indication information is carried by least one time slot on second channel.Such as, may be received in 1,2 or 3 time slots and carry an AS mode indication information, the number M namely carrying at least one time slot of an AS mode indication information is positive integer.
Alternatively, when using multiple time slot to send AS mode indication information, can be 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 the call number of time slot call number or starting time slots according to the rule that base station side is identical.Such as, subscriber equipment can according to formula (1)-(7) above, based on the Connection Frame Number CFN of period 1 ACI_Update_cycle and second channel, obtain the call number of the starting time slots of at least one time slot.When period 1 ACI_Update_cycle is the integral multiple of TTI, according to the bit side-play amount N in one time slot shared by the number M of at least one time slot of a carrying AS mode indication information and AS mode indication information
off1, based on the Connection Frame Number CFN of period 1 ACI_Update_cycle and second channel, obtain the call number of the starting time slots of at least one time slot.If ACI_Update_cycle is the integral multiple of TTI, then can ensures that UE changes AS pattern at sub-frame boundary, conveniently carry out antenna selection operation.
Fig. 3 is the flow chart of the antenna selection procedure of another embodiment of the present invention.In the embodiments of figure 3, UE representative of consumer equipment, NodeB represents base station.
301, after UL CLTD applies, when certain root antenna of UE is in poor-performing for a long time, NodeB sends directive command order by HS-SCCH to UE, prepares to adopt AS pattern to indicate UE.
302, UE, after receiving the order sent in step 301, sends acknowledge message to NodeB.This acknowledge message can be ACK (confirmation) or NACK (negative acknowledgement).What suppose to send in step 302 is ACK message.
303,12 or 18 time slots after NodeB receives the ACK message of UE, order comes into force.After this NodeB starts according to period 1 ACI_Update_cycle, in F-PCICH channel, send AS mode indication information to UE.Before order comes into force, NodeB still sends the indication information of BF in F-PCICH channel.
304, UE monitors F-PCICH, obtains the AS mode indication information that NodeB sends on F-PCICH.The mode of transmitting-receiving AS mode indication information can refer to described in Fig. 1 and Fig. 2, therefore no longer repeated description.
305, UE, according to received AS mode indication information, determines used AS pattern.The AS pattern used comprises an AS pattern or the 2nd AS pattern.Such as, under an AS pattern, subscriber equipment uses the first antenna (physical antenna 1 such as, in table 1) to send all uplink physical channels except S-DPCCH, and use the second antenna (physical antenna 2 such as, in table 1) to send S-DPCCH.Under the 2nd AS pattern, subscriber equipment uses the first antenna to send S-DPCCH, and uses the second antenna to send all uplink physical channels except S-DPCCH.The embodiment of the present invention is not limited to this example, and the send mode that such as an AS pattern and the 2nd AS pattern can be referred to exchanges.
306, UE, according to determined AS pattern, sends data to NodeB.Wherein, UE sends pilot frequency information by DPCCH and S-DPCCH to NodeB.Hereinafter, the pilot frequency information that DPCCH sends is called dominant pilot information, the pilot frequency information that S-DPCCH sends is called auxiliary pilot frequency information.
Alternatively, in one embodiment, auxiliary pilot frequency information is without the need to continuous transmission.Send S-DPCCH according to second round (being hereinafter designated as UE_SDPCCH_DTX_cycle), this S-DPCCH carries pilot frequency information, and each transmission continues the 3rd time span (being hereinafter designated as UE_SDPCCH_burst).The interruption of auxiliary pilot frequency information sends, and can save UE transmitting power, reduces uplink interference.
307, NodeB monitors the pilot frequency information (i.e. dominant pilot information) that DPCCH sends on the dpcch to obtain UE, monitor S-DPCCH with the pilot frequency information obtaining UE and send on S-DPCCH (namely, auxiliary pilot frequency information), and the dominant pilot information listened to according to one or many and auxiliary pilot frequency information determine the AS pattern that described subscriber equipment uses, and generate corresponding AS mode indication information.
When UE is interrupted the auxiliary pilot frequency information of transmission, NodeB according to UE_SDPCCH_DTX_cycle second round, can monitor S-DPCCH, and each monitoring continues the 3rd time span UE_SDPCCH_burst.
308, NodeB, according to the similar mode of step 304, according to period 1 ACI_Update_cycle, periodically sends AS mode indication information to UE in F-PCICH channel, subsequent step and above-mentioned steps 304-307 similar, therefore repeat no more.
UE is after receiving AS mode indication information, if the AS pattern indicated by finding changes, then changes the AS pattern used.If UE receives new directive command order, then order switches accordingly as indicated.Such as, if new order instruction is switched to BF pattern, then UE can be switched to BF pattern after this new order comes into force.
Therefore, the embodiment of the present invention only needs on the first channel directive command order indicating user to enter AS pattern, and indicates any AS pattern of concrete use by second channel to user, thus can save order resource.
Before or after said process, UE and NodeB can receive base station controller to activation or the CLTD pattern of deexcitation subscriber equipment or the configuration of single shot mode, so also can save order resource.
The embodiment of the present invention can realize using AS pattern as normality, and F-PCICH is interrupted transmission AS mode indication information, and the update cycle of AS pattern controls short than order.In addition, if under AS pattern, auxiliary pilot frequency information is interrupted transmission, then can save UE transmitting power, reduces uplink interference.
On the other hand, if ACI_Update_cycle is the integral multiple of TTI, then can ensures that UE changes AS pattern at sub-frame boundary, conveniently carry out antenna selection operation.
In the embodiment of Fig. 3, UE, after receiving order, waits for the AS mode indication information that F-PCICH sends, determines used AS pattern according to this AS mode indication information.But the embodiment of the present invention is not limited thereto.First UE can select an AS pattern (an AS pattern or the 2nd AS pattern) to try out after receiving order, the process of step 306-308 is performed according to selected AS pattern, namely determine that whether the AS pattern selected by UE is suitable by NodeB according to the major-minor pilot frequency information that UE sends, and in the corresponding time slot of the upper F-PCICH once sent, carry corresponding AS mode indication information according to determination result, whether change AS pattern to indicate UE.
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 present invention is not limited to these numerical examples, but the length of these times can be adjusted as required.Such as, UE_SDPCCH_DTX_cycle is less, then NodeB can sample channel situation several times more, and channel estimating can be more accurate.ACI_Update_cycle is less, and NodeB multiplely can send AS mode indication information several times, can increase the accuracy of transmission.
