Abstract

A user equipment (UE) is described. The UE receives, from a base station apparatus, a radio resource control message including first information used for configuring a number of repetitions for transmission of a transport block. The UE also receives, from the base station apparatus, a radio resource control message including second information used for configuring a pattern of redundancy version for the repetitions for the transmission of the transport block. The pattern of the redundancy version is any one of a first pattern and a second pattern. The UE also performs, based on the first information and the second information, to the base station apparatus, the repetition for the transmission of the transport block. The same redundancy version used for the repetitions for the transmission for the transport block is a redundancy version “zero.”
