INTERFERENCE MANAGMENT OF DEVICE-TO-DEVICE COMMUNICATION IN A CELLULAR COMMUNICATION SYSTEM

摘要

In a cellular communication system, pre-codlng MIMO parameters are assigned for transmission of device-to-device (D2D) signals between D2D mobile devices to minimize interference at unintended recipient devices (receiving proximate devices). The pre-codlng MIMO parameters are transmitted from a base station to a transmitting D2D mobile device over a subset of defined downlink cellular communication resources defined by a communication specification for downlink transmission from base stations to mobile wireless devices. The pre-codlng MIMO parameters are determined based on channel characteristics of at least an Interference channel where the Interference channel is between a D2D transmitting device and a proximate receiving mobile device (unintended recipient device). The pre-coding MIMO parameters are determined to facilitate interference management at the receiving proximate mobile device when the pre-coded transmission signal Is received through the interference channel.
