Description
Technical field
The present invention relates to the communications field, in particular to a kind of downlink data coding/decoding method and device.
Background technology
WCDMA inserts (Wide band Code Division Multiple Access; Abbreviate WCDMA as) be a kind of the 3rd generation wireless communication system; Its air interface utilization sign indicating number divides multiplex's multiplexing method to carry out the wide-band spread spectrum radio communication, to the upper strata data transport service is provided.
In the air interface of WCDMA, carrier bandwidths is 5 megahertzes (MHz), uses paired frequency range, and one is used for uply, and one is used for descending.Traditional WCDMA, air interface is only used a pair of frequency range (each carrier wave of up-downgoing), Data transmission between terminal and Node B.To next step technology trends of WCDMA, the multi carrier wave high-speed downlink packet access technique has very significantly special advantages.On this basis, multiple-input and multiple-output (Multiple-Input Multiple-Output abbreviates MIMO as) technology is also used rapidly.MIMO can improve the capacity of channel, improves the reliability of channel simultaneously, reduces the error rate.The former is the spatial reuse gain that utilizes mimo channel to provide, and the latter is the space diversity gain that utilizes mimo channel to provide.For mimo system, multipath is used as a favorable factor.Mimo system all adopts many antennas (or array antenna) and multichannel at transmitting terminal and receiving terminal, and the multiple-input and multiple-output of MIMO is to the multipath wireless channel.Flow of transmitted information forms a plurality of information streams through Space Time Coding.These many substreams are launched by a plurality of antennas, behind space channel, are received by a plurality of reception antennas.The advanced Space Time Coding of multi-aerial receiver utilization is handled these substream of data that can separate and decode, thereby realizes best processing.
In a sub-district, the terminal uses CPICH Common Pilot Channel to estimate respectively the channel of seeing from different antennae.Wherein antenna sends Primary Common Pilot Channel with the modulating mode of " antenna mode one "; An other antenna can send Primary Common Pilot Channel with the modulating mode of " antenna mode two ", also can send secondary common pilot channel with the modulating mode of " antenna mode one ".
Antenna sends Primary Common Pilot Channel with the modulating mode of " antenna mode one "; And; An other antenna is called the MIMO pilot tone mode of " major-minor CPICH Common Pilot Channel " with this MIMO pilot frequency configuration mode that the modulating mode of " antenna mode one " sends secondary common pilot channel.
Under the MIMO pilot tone mode of " major-minor CPICH Common Pilot Channel ", secondary common pilot channel provides the information of the phase difference of the 2nd transmitting antenna of MIMO.The secondary common pilot channel transmitting power is with respect to the ratio of Primary Common Pilot Channel transmitting power, is called " for the power excursion of the secondary common pilot channel of MIMO operation ".
There is and has only a carrier wave sub-district, so use the multi carrier wave high-speed downlink packet access technique, a plurality of sub-districts that must at least will be corresponding with the multicarrier number.For example two carrier wave high speed downlink packet access technologies are used at the terminal, want 2 to utilize high speed downlink packet access technology to carry out the sub-district that data are sent at least, and the carrier wave of one of them sub-district is a main carrier, and the carrier wave of another one sub-district is auxilliary carrier wave; Three carrier wave high speed downlink packet access technologies are wanted 3 sub-districts at least, and the carrier wave of one of them sub-district is a main carrier, and the carrier wave of two other sub-district is auxilliary carrier wave (being respectively an auxilliary carrier wave, auxilliary nd carrier).The sub-district that utilizes high speed downlink packet access technology to carry out the data transmission at main carrier place is called the main carrier sub-district; The sub-district that utilizes high speed downlink packet access technology to carry out the data transmission at auxilliary carrier wave place is called auxilliary carrier cell.
When two carrier wave high speed downlink packet access technology was used at the terminal, main carrier sub-district and auxilliary carrier cell can use MIMO separately at down direction.For example: the main carrier sub-district can be used the MIMO pilot tone mode of " major-minor CPICH Common Pilot Channel " at down direction; Auxilliary sub-district also can be used the MIMO pilot tone mode of " major-minor CPICH Common Pilot Channel " at down direction.It is separate that the MIMO of major-minor sub-district uses, and does not have restriction relation.MIMO pilot tone mode at " major-minor CPICH Common Pilot Channel "; The terminal need estimate the ratio of the secondary common pilot channel transmitting power of this sub-district with respect to the Primary Common Pilot Channel transmitting power, in order to receive high speed descending grouping access data in this cell downlink direction decoding.
The radio network controller of the wireless connections between office terminal and the Radio Access Network is the service wireless network controller at terminal for this reason, and there is and has only a service wireless network controller at a terminal.For a terminal; When being in connection status between it and the Radio Access Network, the service wireless network controller at this terminal is responsible for being connected with the direct of core net, and remains with the contextual information at this terminal; Be responsible for comprising more than the air interface physical layer between the terminal therewith media access control layer simultaneously; Wireless chain control layer, the handover decisions at this terminal is responsible in the processing of agreements such as radio resource control layer; Exterior ring power control, the RAB parameter is to the functions such as mapping of air interface transport channel parameters.
In the prior art, have following defective: service wireless network controller is broadcast to the terminal with the Primary Common Pilot Channel transmission power information of sub-district through system message, and the terminal keeps this information.If auxilliary sub-district is positioned at outside the compass of competency of service wireless network controller, service wireless network controller is not known the ratio of the secondary common pilot channel transmitting power of this auxilliary sub-district with respect to the Primary Common Pilot Channel transmitting power so.So when the operation of multi carrier wave high-speed downlink packet access technique is carried out at service wireless network controller notice terminal; Service wireless network controller is merely able to inform the MIMO pilot tone mode of this auxilliary cell downlink direction use " major-minor CPICH Common Pilot Channel " of terminal, but does not have the ratio information of the secondary common pilot channel transmitting power of this auxilliary sub-district with respect to the Primary Common Pilot Channel transmitting power.
To sum up; During with respect to the ratio of Primary Common Pilot Channel transmitting power, can't confirm that the secondary common pilot channel transmitting power of the auxilliary sub-district at its place causes the lower problem of downlink data decoding accuracy in the secondary common pilot channel transmitting power that can't know auxilliary sub-district in the correlation technique.
