Abstract: In a case of configuring multiple configured grants, signal detection in a base station apparatus is efficiently performed. For configured grant scheduling, by configuring a plurality of time offset values, multiple transmission opportunities are generated. To each of the transmission opportunities, a slot retransmission is applied. In a case that multiple transmission patterns are generated due to the plurality of time offsets, transmission is performed by using a transmission pattern, among the multiple transmission patterns, that causes the number of remaining retransmissions to increase.

Abstract: A terminal apparatus and a base station apparatus efficiently communicate with each other. A terminal apparatus receives a first DCI and determines transmission of a first PUSCH. The first PUSCH is scheduled by the first DCI, a value of a first PUSCH procedure preparation time for the first PUSCH is a first value in a case that a first condition is not satisfied, and the value of the first PUSCH procedure preparation time is a value acquired by adding a second value to the first value in a case that the first condition is satisfied. The terminal apparatus determines the transmission of the first PUSCH in a case that a number of symbols between the first DCI and the first PUSCH is equal to or greater than a number of symbols corresponding to the value of the first PUSCH procedure preparation time.

Abstract: A terminal apparatus is provided. The terminal apparatus includes a receiver configured to receive a first message from a base station apparatus, and a processing unit configured to modify first data radio bearer configuration configured for the terminal apparatus, based on the first message. A first PDCP entity is reconfigured as a packet data convergence protocol (PDCP) entity for the first data radio bearer. A first secrecy key for a source and a second secrecy key for a target are configured for the first PDCP entity as secrecy keys for the first data radio bearer. In a case that the first message includes first information and second information, the second secrecy key for the target of the first PDCP entity is configured based on the second information. In a case that the first message does not include the first information, the first secrecy key for the source is applied to the second secrecy key for the target of the first PDCP entity.
