Abstract
A method may include identifying a repeating frame structure for communication between a MIMO base station and one or more wireless devices, the frame structure including a plurality of slots, with each slot including an uplink portion and a downlink portion, and each uplink portion and downlink portion comprising a plurality of sub-slots, receiving, at the wireless base station, an identification of a first wireless device of the one or more wireless devices, assigning to the first wireless device, a sub-slot in an uplink portion of a static slot in the frame structure, communicating, to the first wireless device, information from which the first wireless device can identify the sub-slot, and communicating with the one or more wireless devices by associating data in the first sub-slot with the first wireless device.
