example 1

[0127] Example 1: If Figure 5 As shown, under the conventional CP, the uplink control information is transmitted using PUCCH Format 3, where the encoding method is shown in Figure 4(a), that is, P=1, and the ACK / NACK response information bit sequence and the CSI information bit sequence For concatenation, since the length of the encoded bit sequence that can be carried in the PUCCH format3 format is 48, RM (48, 0) encoding is used, wherein RM (48, 0) is obtained by performing rate matching on RM (32, 0).

example 2

[0128] Example 2: If Figure 5 As shown, under the conventional CP, the uplink control information is transmitted using PUCCH format3, where the encoding process is shown in Figure 4(b), that is, P=2, and the ACK / NACK response information bit sequence and the CSI information bit sequence After cascading, it is divided into 2 sequences on average, and the lengths of the 2 sequences are respectively and O 2 =(M+N)-O 1 ; Since the coded bit sequence length that can be carried in the PUCCH format3 format is 48, each sequence adopts RM (24, 0) encoding, wherein RM (24, 0) is obtained by rate matching RM (32, 0) .

example 3

[0129] Example 3: If Figure 5 As shown, under the conventional CP, the uplink control information is transmitted using PUCCH format3, where the encoding process is shown in Figure 4(c), that is, P=3, and the ACK / NACK response information bit sequence and the CSI information bit sequence After cascading, it is divided into 3 sequences on average, and the lengths of the 3 sequences are respectively and O 3 =(M+N)-O 1 -O 2 . Since the length of the coded bit sequence that can be carried in PUCCH format3 is 48, each sequence adopts RM(16, O) coding, wherein RM(16, O) is obtained by performing rate matching on RM (32, O).

Abstract

The invention discloses a sending method and device for uplink control information. The sending method comprises the following steps of: determining the transmitted uplink control information according to a high-layer signaling and / or a pre-defined rule, and transmitting the determined uplink control information through a physical uplink control channel (PUCCH). The sending device of the uplink control information comprises a determining unit for determining the transmitted uplink control information according to the high-layer signaling and / or the pre-defined rule, and a transmission unit for transmitting the determined uplink control information through the PUCCH. According to the sending method and device for the uplink control information, the maximum throughput can be ensured and the feedback time delay of the downlink channel can be reduced.

Description
