Abstract:
1. A method for transmitting an uplink signal at a User Equipment (UE) in an Long Term Evolution (LTE) wireless communication system, the method comprising: generating first uplink control information and second uplink control information; multiplexing the first uplink control information and the second uplink control information by using a modulation order corresponding to a length of a bit stream that is generated by sequentially arranging bits for the first uplink control information and bits for the second uplink control information; and simultaneously transmitting the multiplexed first uplink control information and second uplink control information in one or more uplink carriers via a predetermined uplink channel, wherein the first uplink control information is transmitted on a Physical Uplink Control CHannel (PUCCH) of a first uplink carrier among the one or more uplink carriers, and the second uplink control information is transmitted on a Physical Uplink Shared CHannel (PUSCH) of the first uplink carrier or a second uplink cartier among the one or more uplink carriers, wherein the first uplink control information is an ACKnowledgment (ACK)/Negative ACK (NACK), and the second uplink control information is periodic Channel Status Information (CSI), wherein the first uplink carrier is a primary carrier and different from the second uplink carrier; wherein when the first control information requires a lower propagation error rate than the second control information, a MSB (Most Significant Bit) of the bit stream is configured to map the first control information and a first subset of symbols of the predetermined uplink channel for the first control information is configured to have more pilot signal than a second subset of symbols of the predetermined uplink channel for the second control information, where each of the first and the second subsets of symbols includes one or more Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols.
