A mobile station device executes processing on uplink control information by effectively using uplink resources when transmitting the uplink control information. The mobile station device generates a plurality of ACK/NACK sequences by interleaving and dividing ACKs/NACKs for a plurality of cells in a plurality of subframes, and separately encodes the plurality of ACK/NACK sequences. Also, the mobile station device interleaves a plurality of ACKs/NACKs and a scheduling request together.

Embodiments of the present invention provide a feedback information transmission method in a communications system and an apparatus. In this method, UE may determine a codebook size of the feedback information according to a status of a downlink subframe scheduled by the base station

A method of operating a wireless communication device comprises channel coding Channel State Information (CSI) bits jointly with Hybrid Automatic Repeat Request (HARQ) Acknowledgement (HARQ-ACK) bits, multiplexing the jointly coded CSI and HARQ-ACK bits with coded data bits, and transmitting the multiplexed coded CSI and HARQ-ACK bits and coded data bits on a physical uplink shared channel (PUSCH).

A UE according to an embodiment of the present disclosure may receive information about a plurality of beta offset values for determining the number of REs for UCI to be transmitted on a PUSCH, receive DCI scheduling a first PUSCH, and transmit a first HARQ-ACK on the first PUSCH, and transmit the first PUSCH. The plurality of beta offset values may include first beta offset values for a case where the priority of the first HARQ-ACK is identical to the priority of the first PUSCH, and second beta offset values for a case where the priority of the first HARQ-ACK is different from the priority of the first PUSCH.

A terminal apparatus capable of efficiently performing the uplink and/or downlink communication is provided. The terminal apparatus receives higher layer signaling used for configuration of multiple scheduling request configurations, and transmits HARQ-ACK bits and scheduling request bits by using a HARQ-ACK PUCCH resource. Each of the multiple scheduling request configurations corresponds to one or more logical channels. Each of the multiple scheduling request configurations includes an SR PUCCH resource. The scheduling request bits are added to a sequence of the HARQ-ACK bits. In a case that the HARQ-ACK PUCCH resource and SR PUCCH resource overlap with each other in a time domain, a size of the scheduling request bits is given based on a number of scheduling request configurations with the overlapping SR PUCCH resource.

An arrangement is disclosed where in a multi-carrier communication system, the modulation scheme, coding attributes, training pilots, and signal power may be adjusted to adapt to channel conditions in order to maximize the overall system capacity and spectral efficiency without wasting radio resources or compromising error probability performance, etc.
