Short physical uplink shared channel arrangement

Abstract

Various communication systems may benefit from efficient communications. For example, low latency long term evolution (LTE) systems may benefit from a short physical uplink shared channel (PUSCH) arrangement. A method may include operating a user equipment to follow a shortened transmission time interval. The shortened transmission time interval can be an integer number, L, of symbols in length. The method can also include sending a demodulation reference signal in at least a first symbol of the L symbols of the shortened transmission time interval.
