Claim of US Patent No. 10,194,450

1. A method for transmitting control information, comprising:obtaining a resource occupied by first uplink control information (UCI) and obtaining a resource occupied by second UCI;
performing channel encoding on the first UCI according to the resource occupied by the first UCI to obtain an encoded bit sequence of the first UCI, and performing channel encoding on the second UCI according to the resource occupied by the second UCI to obtain an encoded bit sequence of the second UCI; and
mapping the encoded bit sequence of the first UCI and the encoded bit sequence of the second UCI to a physical uplink channel, so as to transmit to a base station, wherein
the first UCI is periodic channel state information CSI and the second UCI is a hybrid automatic repeat request-acknowledgment message HARQ-ACK; or
the first UCI is periodic channel state information CSI and the second UCI is a hybrid automatic repeat request-acknowledgment message HARQ-ACK and a scheduling request SR, wherein the obtaining a resource occupied by first UCI comprises:
in a case that the periodic CSI comprises CSI of a first reporting type or CSI of a second reporting type, obtaining a resource occupied by the CSI of the first reporting type or the CSI of the second reporting type; or,
in a case that the periodic CSI comprises CSI of a first reporting type and CSI of a second reporting type, obtaining a resource occupied by the CSI of the first reporting type and discarding the CSI of the second reporting type, or obtaining a resource occupied by the CSI of the first reporting type and obtaining a resource occupied by the CSI of the second reporting type, wherein the performing channel encoding on the first UCI according to the resource occupied by the first UCI to obtain an encoded bit sequence of the first UCI and performing channel encoding on the second UCI according to the resource occupied by the second UCI to obtain an encoded bit sequence of the second UCI comprise:
in a case that the resource is the number of modulation symbols, calculating the number of encoded bits occupied by the first UCI according to the number of modulation symbols occupied by the first UCI, and calculating the number of encoded bits occupied by the second UCI according to the number of modulation symbols occupied by the second UCI; performing channel encoding on the first UCI according to the number of encoded bits occupied by the first UCI to obtain the encoded bit sequence of the first UCI, and performing channel encoding on the second UCI according to the number of encoded bits occupied by the second UCI to obtain the encoded bit sequence of the second UCI; or,
in a case that the resource is the number of encoded bits, performing channel encoding on the first UCI according to the number of encoded bits occupied by the first UCI to obtain the encoded bit sequence of the first UCI, and performing channel encoding on the second UCI according to the number of encoded bits occupied by the second UCI to obtain the encoded bit sequence of the second UCI, wherein
the number of modulation symbols occupied by the first UCI satisfies Q?CSI=Q? or Q?CSI=Q??Q?HARQ-ACK, and
the number of modulation symbols occupied by the second UCI satisfies
Q?HARQ-ACK=|Q?*(OHARQ-ACK/(OCSI+OHARQ-ACK))*?offset|, or
Q?HARQ-ACK=|Q?*(OHARQ-ACK/(OCSI+OHARQ-ACK))|, or
Q?HARQ-ACK=|(?)*Q?*(OHARQ-ACK/OCSI)|, or
Q?HARQ-ACK=|(OHARQ-ACK*((MSCPUCCH*NsymbPUCCH)/VSF)*?offset)/OCSI)|, or
Q?HARQ-ACK=NsymbHARQ-ACK*MSCPUCCH,
wherein Q? is capacity of the physical uplink channel, OHARQ-ACK is the total number of information bits of the HARQ-ACK, OCSI the total number of information bits of the periodic CSI, ?offset is a value configured semi-statically by high-layer signaling or a preset value, MSCPUCCH is the number of subcarriers allocated to the physical uplink channel, NsymbPUCCH is the number of time domain symbols, used for transmitting the UCI, of the physical uplink channel, VSF is the value of a spread spectrum coefficient, and NsymbHARQ-ACK is the number of time domain symbols used for transmitting the HARQ-ACK.
