Abstract

A technique includes multiplying, by a user device, a first uplink control information, associated with a first control channel format length, with a first orthogonal signal to obtain a first spread control signal, multiplying, by the user device, a second uplink control information, associated with a second control channel format length, with a second orthogonal signal that is different than the first orthogonal signal to obtain a second spread control signal, the second control channel format length being different than the first control channel format length, receiving, by the user device, a first resource grant indicating one or more resource blocks for uplink transmission, the first resource grant associated with or provided for the first uplink control information, and transmitting, by the user device, at least partially simultaneously via the one or more resource blocks, the first spread control signal and the second spread control signal.
