Abstract:
1. A method in a user equipment (UE) for transmitting control information and user data in a communication system, the method comprising: modulating encoded rank information bits and encoded uplink (UL) data based on a corresponding modulation scheme; mapping modulated rank information and at least one modulated UL data in a subframe of a physical uplink shared channel, the subframe comprising two slots, each slot comprising a reference signal; and transmitting the subframe including the rank information and the UL data, wherein the modulated rank information is mapped to a Single Carrier Frequency Division Multiplexing Access (SC-FDMA) symbol that is separated from the reference signal by at least one symbol comprising hybrid automatic repeat request acknowledgment information, and wherein some of the modulated UL data is mapped to the SC-FDMA symbol that is separated from the reference signal by at least one symbol.
