Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the method for configuring power controlling parameter of high-speed sharing channel in a kind of TD-SCDMA system.
Background technology
High speed downlink packet inserts (HSDPA, High Speed Downlink Packet Access) technology, is a kind of technology that provides the high-speed down data business at the multi-user, is suitable for the business of download messages in a large number such as multimedia, Internet.HSDPA has introduced new transmission channel: high speed descending sharing channel (HS-DSCH, High Speed Downlink Shared Channel), the user shares descending sign indicating number resource and power resource, carries out time division multiplexing.This structure is applicable to sudden Packet data service.In TD SDMA (TD-SCDMA, Time Division Synchronization Code DivisionMultiple Access) system, down physical channel HS-SCCH 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, subscriber equipment (UE, User Equipment) can find HS-DSCH resource according to physical layer information such as the code channel of its appointment, time slot, modulation systems into this UE configuration, simultaneously, UE feeds back the channel quality information (CQI, Channel QualityIndicator) of this HS-DSCH channel and data block decoded information (ACK/NACK) etc. by sending the HS-SICH channel to Node B (Node B).
In the TD-SCDMA system, according to 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) agreement, HS-SCCH channel and HS-SICH channel that Node B distributes to UE are to occur in pairs, Node B is that UE may distribute 1～4 HS-SCCH physical channel, corresponding, also be assigned 1～4 HS-SICH physical channel for this UE, be that all HS-SCCH that a UE distributes are called a HS-SCCH collection, every HS-SCCH physical channel that the corresponding HS-SICH collection that a correspondence is also arranged, HS-SCCH are concentrated is corresponding with the HS-SICH physical channel that HS-SICH concentrates.UE only may use the HS-SICH of a HS-SCCH and a correspondence in this set at a TTI (Transmit Time Interval, transmission time interval) constantly.At different TTI, different HS-SCCH and HS-SICH that UE may use this HS-SCCH collection and HS-SICH to concentrate.At certain TTI, which HS-SICH that UE uses which concentrated HS-SCCH of HS-SCCH and corresponding HS-SICH thereof to concentrate actually? UE identifies according to the UE that HS-SCCH upward carries to judge, UE uses the HS-SCCH that conforms to himself sign, and uses the corresponding HS-SICH of HS-SCCH therewith.
In the TD-SCDMA system, UE sends to the HS-SICH of Node B and HS-SCCH that corresponding NodeB sends to UE needs to carry out power control.No matter be the power control of the HS-SICH that finishes of UE, still the power control of the HS-SCCH that is finished by Node B all comprises two control procedures of open Loop Power control and closed power control.
The open Loop Power control process is applied to the performance number of UE initialization HS-SICH and the performance number of Node B initialization HS-SCCH.Subsequently, when UE receives follow-up HS-SCCH, when receiving the HS-SICH of follow-up UE feedback with Node B, go up TPC (the Transmit Power Control of carrying according to HS-SCCH and HS-SICH, transmission power control) order, to adopt closed power control, adjust the closed loop transmitted power.
According to the 3GPP agreement, in the TD-SCDMA system, the formula that UE calculates the Initial Trans of HS-SICH is:
P
HS-SICH=PRX
HS-SICH+ L
PCCPCH... ... ... ... ... ... .. (formula 1)
Wherein,
P
HS-SICHTransmission power level (dBm);
PRX
HS-SICH: be the HS-SICH received power that expectation UE receives, high level is notified to UE by the information unit in the RRC agreement " descending HS-PDSCH message " (" Downlink HS-PDSCHInformation ");
L
PCCPCH: the metrophia compensation value of UE, the information unit " Primary CCPCH Tx Power " of UE in can read system message piece 5 or 6 obtains, and perhaps is notified to UE from high level by the information unit the RRC agreement " Uplink DPCH Power Control info ".
The HS-SICH open Loop Power control process that UE finishes, be applied to the situation of the performance number of UE initial transmissions HS-SICH, subsequently, when UE receives the follow-up HS-SCCH that sends from Node B, carried the parameter TPC of relevant HS-SICH closed power control among this HS-SCCH, UE begins the closed power control procedure of HS-SICH, up to sometime or certain period, UE can not correctly receive the HS-SICH of feedback, and UE restarts open loop HS-SICH power control process.When UE is in the closed power control procedure of HS-SICH, the formula 2 that UE calculates the transmission power level of HS-SICH is:
P
HS-SICH=P
HS-SICH'+TPC step size (TPC) ... ... ... ... ... .... (formula 2)
Wherein:
P
HS-SICH': be the HS-SICH transmission power level of last UE calculating;
TPC step size: for network side is the TPC adjustment step parameter of UE configuration by high-level signaling, step-length is 1,2 or 3;
TPC: for UE receives the TPC value that HS-SCCH goes up carrying, when TPC was " UP ", the power of this emission of UE HS-SICH was P
HS-SICH=P
HS-SICH'+TPC step size (increase transmitting power), when TPC was " DOWN ", the power of this emission of UE HS-SICH was P
HS-SICH=P
HS-SICH'-TPC step size (minimizing transmitting power);
UE is when the power of actual transmission HS-SICH, at first, the high level of UE obtains the transmission power level of HS-SICH according to the computing formula (formula 1 and formula 2) of open loop or closed power control, the physical layer of UE will be used " Ack-Nack Power Offset " parameter then, the power excursion that is used for the transmitting power of HS-SICH, the performance number of finally launching HS-SICH as UE is as formula 3.
P
HS-SICH=P
HS-SICH+ Ack-Nack Power Offset.................................. (formula 3)
Wherein:
The P on equal sign the right
HS-SICHThe HS-SICH transmitting power that calculates for the high level of UE;
The P on the equal sign left side
HS-SICHBe the actual emission power after the power offset (UE physical layer process) that has added HS-SICH.
UE also needs the actual block error rate according to the HS-SCCH that receives, dispose HS-SCCH bLock error rate desired value (BLER Target with high-level signaling to this UE, transmission block error rate desired value), calculate TPC, as: the HS-SCCH actual block error rate that receives as UE during greater than the object block error rate, the TPC that UE calculates is " UP " command word, otherwise, then the TPC of UE calculating is " DOWN " command word, UE is carried on this TPC order on the HS-SICH, send to Node B, be used for the closed power controlling value that NodeB adjusts descending HS-SCCH.
In present 3GPP agreement, indicated in the information unit (" HS-SCCH Info ") that network side sends to the high-level signaling of UE and comprised the parameter that these are relevant with power control, be specially:
The high level that is used for UE calculates the pRX of up HS-SICH open loop transmit power
HS-SICH
Adjust " the TPC step size " of purpose of closed loop transmit power;
The physical layer of UE is adjusted the power excursion (" Ack-Nack PowerOffset ") of actual HS-SICH transmitting power;
Be used for the transmission block error rate desired value (" BLERTarget ") that UE calculates the TPC of descending HS-SCCH.
Network side sends in the information unit (" HS-SCCH Info ") in the high-level signaling of UE, for UE has disposed a HS-SCCH collection, and with a HS-SICH set pair should, only using a HS-SCCH and the HS-SICH in these two set, UE can use other HS-SCCH and HS-SICH in these two set at different TTI to UE simultaneously at certain TTI.
Obviously, when UE calculates HS-SICH open loop and purpose of closed loop transmit power value, when the physical layer of UE is adjusted actual HS-SICH transmit power offset, when UE calculates the TPC command word of HS-SCCH, the power contorl parameters value among " HS-SCCH " that is adopted: " PRX
HS-SICH", " TPC step size ", " Ack-Nack Power Offsaet " and " BLER Target ", the not different HS-SICH that should concentrate along with different HS-SCCH that adopt HS-SCCH to concentrate and HS-SICH and difference.
Yet, according to present 3GPP agreement, sending in the information unit " HS-SCCH Info " of the high-level signaling of UE at network side, every HS-SICH that every HS-SCCH that concentrates for HS-SCCH and HS-SICH concentrate has disposed the power contorl parameters value.When these power contorl parameters values because different HS-SCCH and HS-SICH and not simultaneously, if UE has also adopted every power contorl parameters value that HS-SCCH is different with HS-SICH, come the rated output controlling value, then UE can not correctly calculate and realize power control process.
