Method and apparatus for transmitting and receiving uplink control information in wireless communication system

1. A method for receiving uplink control information from a base station in a wireless communication system, the method for receiving the uplink control information comprises:

allocating resources for transmitting uplink control information;

transmitting resource allocation information of the resources; and

receiving uplink control information from at least one user equipment through the resources, and

wherein the resources are multiplexed so that a single Physical Uplink Control Channel (PUCCH) format can be used by a plurality of user equipments, a plurality of information, or a plurality of random access opportunities by enabling the plurality of user equipments, the plurality of information, or the plurality of random access opportunities to use different constellations each other, and

wherein the resource allocation information includes an index of the resource and information on a constellation.

2. The method of claim 1 , wherein the information on the constellation corresponds to a designation of the constellation.

3. The method of claim 1 , wherein the information on the constellation corresponds to a phase rotation value of the constellation.

4. The method of claim 1 , wherein a scheduling request (SR) and an Acknowledgement/Non-Acknowledgement (ACK/NACK) respective to two user equipments are multiplexed and transmitted through the resources.

5. The method of claim 4 , wherein, when the ACK/NACK is equal to or larger than 2 bits, the ACK/NACK is bundled and transmitted.

6. A method for transmitting uplink control information from a user equipment of a wireless communication system, the method for transmitting the uplink control information comprises:
