wherein for (2k−1) th and (2k) th UCI symbols in time,

directly using elements of the orthogonal sequences corresponding to the (2k−1) th and (2k) th UCI symbols to build a first set of pairs of Space-Time Block Coding (STBC) codes, and

performing conjugation transformation on elements of the generated orthogonal sequences corresponding to the (2k−1) th and (2k) th UCI symbols to build a second set of pairs of STBC codes;

wherein the transmitting the PUCCH comprises:

transmitting the PUCCH with the first set of pairs of STBC codes via a first antenna; and

transmitting the PUCCH with the second set of pairs of STBC codes via a second antenna,

where k is a positive integer and smaller than or equal to m/2.

3. The method according to claim 2 , wherein when m is an odd number, the method further comprising:

performing Cyclic Delay Diversity (CDD) or Space Orthogonal-Resource Transmit Diversity (SORTD) on a last UCI symbol in time among the m UCI symbols to build CDD or SORTD codes for the last UCI symbol.

4. The method according to claim 1 , wherein the PUCCH has at least one first UCI symbol each of which is not allocated between two of the at least three RS symbols.

5. The method according to claim 1 , wherein a number of the UCI symbols between a third RS symbol and the second RS symbol of the at least three RS symbols is not equal to 2.

6. The method according to claim 5 , wherein the number of the UCI symbols between the third RS symbol and the second RS symbol is smaller than 2.

7. An information transmission apparatus, comprising a processor, a memory, and a transmitter, the memory having instructions stored therein, which when executed by the processor, causes the processor to:

control the transmitter to transmit a PUCCH having at least three Reference Signal (RS) symbols;

wherein only Uplink Control Information (UCI) symbols are located between a first RS symbol and a second RS symbol of the at least three RS symbols, and a number of the UCI symbols between the first RS symbol and the second RS symbol is 2, and

wherein all symbols in the PUCCH are allocated in a same frequency resource.

8. The apparatus according to claim 7 , wherein the processor is further configured to:

generate an orthogonal sequence for each UCI symbol among m UCI symbols in the PUCCH, wherein m is an integer, and greater than or equal to 2; and

perform conjugation transformation on elements of the generated orthogonal sequences corresponding to the (2k−1) th and (2k) th UCI symbols to build a second set of pairs of STBC codes;

wherein the transmitter is configured to:

transmit the PUCCH with the first set of pairs of STBC codes via a first antenna; and

transmit the PUCCH with the second set of pairs of STBC codes via a second antenna,

where k is a positive integer and smaller than or equal to m/2.

9. The apparatus according to claim 8 , wherein when m is an odd number, before the PUCCH is transmitted, the processor is further configured to:

perform Cyclic Delay Diversity (CDD) or Space Orthogonal-Resource Transmit Diversity (SORTD) on a last UCI symbol in time among the m UCI symbols to build CDD or SORTD codes for the last UCI symbol.

10. The apparatus according to claim 7 , wherein the PUCCH has at least one first UCI symbol each of which is not allocated between two of the at least three RS symbols.

11. The apparatus according to claim 7 , wherein a number of the UCI symbols between a third RS symbol and the second RS symbol of the at least three RS symbols is not equal to 2.
