摘要:
A method of transmitting pilot signals in a system which performs communication using two or more earners comprises transmitting first pilots and second pilots from at least one user equipment to a base station, the first and second pilots, which are transmitted from the at least one user equipment, being multiplexed by code division multiplexing, and the first and second pilots, which are transmitted from a specific user equipment, having different transmission powers, and transmitting data from the at least one user equipment to the base station depending on the first pilots and the second pilots. Since many UEs can transmit CQ pilots, exact channel estimation can be performed and thus communication efficiency can be improved.

A portable device, such as a mobile terminal or user equipment, for encoding uplink acknowledgments to downlink transmissions. The portable device includes a receiver configured to receive a plurality of data blocks, such that each of the data blocks include an associated cyclic redundancy check (CRC), and a processor configured to determine received status for each of the data blocks by checking the CRC of each of the data blocks. The portable device further includes a transmitter for transmitting a response sequence which indicates the received status of all of the data blocks.

A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals in a mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal.
