Abstract

Discloses a method and a device in a node for wireless communications. The node receives a first information block, the first information block being used to determine a first offset value; and determines a first bit block and transmits a target PUSCH, where a target bit sequence is used for generating the target PUSCH, and the first bit block is used for generating a first bit sequence, the first bit sequence belonging to the target bit sequence, and the first offset value is used to determine a number of bits comprised in the first bit sequence; when a target condition is satisfied, the number of HARQ-ACK bit(s) comprised in the first bit block is used to determine whether the first reference bit block comprises a bit other than the first bit block. The present application can enhance the resource utilization ratio of HARQ multiplexing.
