Below in conjunction with accompanying drawing the method and apparatus of transmitting uplink control information on row shared channel physically described according to an embodiment of the invention with reference to specific embodiment.
Fig. 1 shows the flow chart of the method for transmitting uplink control information on the shared channel of row physically PUSCH according to an embodiment of the invention.In the method shown in Fig. 1, in described PUSCH, upstream data is mapped to multiple space layer of multiple code word.Specifically, in a step 101, for different code word, the different offset parameters of described ascending control information relative to the code rate of described upstream data are set.In a step 102, based on described different offset parameter, determine the symbol quantity after the ascending control information coded modulation that maps in each space layer.
In the above-mentioned methods, described PUSCH support space is multiplexing, can support multiple space layer.The information that PUSCH transmits can be mapped to multiple space layer of multiple code word.Be specifically described for LTE-A Rel10 below.2,3 or 4 space layer can be supported for LTE-A Rel-10, PUSCH.When supporting multiple space, PUSCH is by two code word CW0, CW1 transmission informations.When support two space layer, each code word is mapped to a space layer.When support 3 space layer, CW0 is mapped to space layer 1, CW2 and is mapped to space layer 2 and 3.When support 4 space layer, two code words are respectively mapped to two space layer.Above-mentioned situation is only exemplary.Method of the present invention not only goes for LTE-A Rel10, goes for the communication system of the multiplexing PUSCH of other support spaces that are existing and exploitation in the future.
In the method shown in Fig. 1, can ascending control information is multiplexing with upstream data together with transmit.In described PUSCH, upstream data is mapped to multiple space layer of multiple code word.For different code word, because channel quality is different, usually adopt different modulation and coded system.In order to make the UCI symbol after coded modulation that each space layer of wherein transmitting uplink control information carries identical, in a step 101, for different code word, the different offset parameters of ascending control information relative to the code rate of upstream data are set.Described offset parameter such as can be indicated by RRC signaling clearly by high level, or impliedly can derive based on predetermined mode.Such as, can based on the summation of two code word spectrum efficiencies, or based on the average spectral efficiency (ase) of two code words, or based on spectrum efficiency etc. maximum in two code words, derive this offset parameter.It should be appreciated by those skilled in the art that and the offset parameter of the ascending control information on each layer relative to the code rate of upstream data can also be set according to any other mode existing.Then, in a step 102, based on the different offset parameters for each code word, determine by with the symbol quantity after the ascending control information coded modulation that the corresponding each space layer of code word selected maps.
Those skilled in the art should understand that, after symbol quantity after determining the ascending control information coded modulation mapped in each space layer, correspondingly can obtain the symbol after ascending control information coded modulation, the equivalent layer being mapped to corresponding code word transmits.Do not repeat at this.
According to one embodiment of present invention, wherein said ascending control information comprises hybrid automatic repeat-request-response HARQ-ACK/NACK and/or rank indication information RI.Such as, according to the consensus that LTE-A Rel 10 reaches, HARQ-ACK/NACK and/or RI repeats on all layers of two CW, and aims in time (namely RE aims at).Although the modulation symbol after the coded modulation of HARQ-ACK/NACK and/or RI that each layer carries takies identical resource elementary cell RE, but as mentioned above because the channel quality that different CW is corresponding is different, the coded modulation level of the upstream data on different CW is different, so HARQ-ACK/NACK and/or RI of carrying also has different code rate offset parameters on different CW.Therefore in a step 101, for different code word, the different offset parameters of ascending control information relative to the code rate of upstream data are set.Such as, when PUSCH channel supports two code word CW0 and CW1, different offset parameters can be set respectively for CW0 and CW1

when arranging offset parameter
with
time, also should consider that HARQ-ACK/NACK and/or RI carries out the diversity gain of redundancy that repetition produces and acquisition on all layers of all code words, thus the coded modulation speed that can arrange higher HARQ-ACK/NACK and/or RI is with maximum resource utilance.
Then, in a step 102, based on described different offset parameter, and based on the Resourse Distribute of initial p USCH transmission and the Resourse Distribute of current PUSCH transmission, determine the symbol quantity after ACK/NACK and/or the RI coded modulation that maps in each space layer corresponding with all code words.Usually the Resource Block dispatched is determined by subcarrier number and these two factors of DFT pre-coded symbols quantity.Described Resourse Distribute can be such as the scheduling bandwidth of PUSCH transmission, can be expressed as the quantity of the subcarrier on dispatched Resource Block (such as subframe).Alternatively, described Resourse Distribute is the scheduling duration of PUSCH transmission, can be expressed as the quantity of the DFT pre-coded symbols on dispatched Resource Block.
When PUSCH channel supports two code word CW0 and CW1, according in LTERel-8 for the calculating of the symbol quantity after the coded modulation of the UCI of individual layer, the code modulated symbol quantity of HARQ-ACK and/or RI on two CW can be determined by following formula respectively:
For CW0
And for CW1
Wherein O is the quantity of original bit of HARQ-ACK/NACK and/or RI before coding;
be the scheduling bandwidth of the initial p USCH transmission in units of subcarrier, be expressed as the quantity of the subcarrier on dispatched Resource Block;

In order to be aligned in all layers of two CW HARQ-ACK/NACK and/or RI coded modulation after symbol, and aim in time, should the final amt of HARQ-ACK/NACK and/or RI after coded modulation on each layer be defined as identical, such as, can determine as follows:
Alternatively, according to another embodiment of the invention, the final amt of HARQ-ACK/NACK and/or RI after coded modulation on each layer can be defined as Q

Because channel quality corresponding to the different CW of PUSCH is different, the coded modulation level of the upstream data on different CW is different, thus when select for carrying the CW difference of CQI and/or PMI time, this CQI and/or PMI has different code rates.Therefore in a step 101, for different code word, the different offset parameters of CQI and/or PMI relative to the code rate of upstream data are set.Such as consider the situation supporting two code word CW0 and CW1 at PUSCH channel.If select CW0 to carry CQI and/or PMI, then offset parameter can be set for CW0
