Patent ID: 8670430

Claim:
A method of transmitting uplink signal in a wireless communication system, the method comprising: mapping the uplink signal comprising control information and transport blocks corresponding to data information to a plurality of spatial resources; and transmitting the uplink signal to a base station by using the plurality of spatial resources, wherein the transport blocks corresponding to data information are mapped to all of the plurality of spatial resources, wherein the control information is mapped to specific spatial resources from the plurality of spatial resources, wherein the control information is multiplexed with a specific transport block among the transport blocks corresponding to the data information, and wherein the number of modulated symbols (Q) per spatial resource for the control information is determined by a following Equation 1: Q =ceiling(Beta offset ×1 /CR data ×1 /Q mod ×T ) <Equation 1> (where the ceiling(x) is a round-up function of the x, wherein the Beta offset is an offset value, the CR data is a coding rate of the specific transport block among the transport blocks, the Q mod is a modulation order, and the T is a number of input bits for the control information).
