Title:
NON-ORTHOGONAL MULTIPLE ACCESS FOR MACHINE TYPE COMMUNICATIONS IN A WIRELESS COMMUNICATIONS NETWORK
Document Type and Number:
WIPO Patent Application WO/2020/192409
Kind Code:
A1
Abstract:
A method of obtaining channel state information estimates in a wireless communications network which supports wireless communications between UEs and multi input multi output base stations and wireless machine type communications between machine type communication devices and multi input multi output base stations, the method comprising each of or at least some of the machine type communication devices, applying a device-specific interleaving pattern to training signals of the machine type communication device, applying a device-specific sparse mapping pattern to the training signals of the machine type communication device, sending an uplink transmission from the machine type communication device comprising the training signals of the machine type communication device and data signals of the machine type communication device, each of or at least some of the UEs, sending an uplink transmission from the UE comprising training signals of the UE and data signals of the UE, and at least one multi input multi output base station, receiving an uplink signal comprising an uplink transmission from each of or at least some of the machine type communication devices and an uplink transmission from each of or at least some of the UEs, using the device-specific interleaving pattern and the device-specific mapping pattern of each of the machine type communication devices to distinguish the training signals of each machine type communication device from remaining machine type communication devices and from the training signals of each UE, and using the training signals of each of or at least some of the UEs to obtain channel state information estimates for each of or at least some of the UEs and using the training signals of each of or at least some of the machine type communication devices to obtain channel state information estimates for each of or at least some of the machine type communication devices.
