1. A computer-implemented method performed using a wireless mobile computing device, the method comprising:
- requesting to form a signal, the signal comprising sub-carriers on at least two different frequencies wherein a first frequency of a first sub-carrier includes at least two different time slots and wherein a second frequency of a second sub-carrier includes at least two different time slots;
requesting assignment of a first data portion to one of the time slots of the first sub-carrier;
requesting assignment of a second data portion to another of the time slots of the first sub-carrier with a first frequency; and
requesting assignment of a demodulation reference signal (DMRS) pattern in each sub-carrier of the signal, the DMRS pattern in a resource block of the signal, the DMRS pattern orthogonal in frequency and time with respect to a DMRS pattern in a resource block of another signal from another device, the resource block of the signal to overlap in frequency and time with the resource block of the another signal.

Abstract
Techniques are described for forming signals for transmission to a receiver. Two transmitters can form resource blocks with different Physical Uplink Control Channel (PUCCH) demodulation reference signal (DMRS) patterns that are orthogonal over time and/or frequency to each other. The transmitters can simultaneously transmit the same resource block but with different DMRS patterns. If a receiver is mounted with two antennas, the receiver can utilize a MIMO receiver to differentiate resource blocks from two transmitters.
