1. A method of resource allocation for non-orthogonal multiple access signals, comprising:

  • signaling resource region assignments to devices of respective device groups in a plurality of device groups, the resource region assignments assigning a plurality of resource regions of a resource block to the respective device groups, the plurality of device groups comprising a first device group and a second device group; and

    receiving the non-orthogonal multiple access signals from the devices of the respective device groups, wherein non-orthogonal multiple access signals from devices in the first device group are received synchronously with non-orthogonal multiple access signals from other devices in the first device group, the non-orthogonal multiple access signals from devices in the first device group are received asynchronously with non-orthogonal multiple access signals from devices in the second device group, and the non-orthogonal multiple access signals from devices in the second device group are received synchronously with non-orthogonal multiple access signals from other devices in the second device group.
