Abstract
Various aspects described herein relate to cancelling interference in wireless communications. Energy level detection of a received signal can be performed to determine an allocation size and position corresponding to an interfering device in the received signal. An interference demodulation reference signal (DM-RS) and cyclic shift of the interfering device in the received signal can be determined. It can be determined whether to apply successive interference cancellation on the received signal, based at least in part on the allocation size and position and the DM-RS and cyclic shift, to cancel interference from the interfering device.
