Abstract:
1. A method of coordinating communications between a wireless MIMO base station and one or more wireless devices, comprising: identifying a repeating frame structure for communication between the MIMO base station and the 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 MIMO base station, an identification of a first wireless device of the one or more wireless devices; assigning to the first wireless device, to the exclusion of others of the one or more wireless devices, a sub-slot in an uplink portion of a static slot in the frame structure, wherein communicating, to the first wireless device, information from which the first wireless device can identify the assigned sub-slot; communicating with the one or more wireless devices by associating data in the assigned sub-slot with the first wireless device, and allocating one or more sub-slots within a plurality of dynamic slots in the frame structure to the first wireless device by determining information relating to a traffic load for the first wireless device, wherein the static slot is interleaved in the frame with the plurality of dynamic slots; and communicating with each of the one or more wireless devices such that, while the one or more wireless devices are associated with the MIMO base station, each of the one or more wireless devices is assigned at least one sub-slot in an uplink portion of a static slot and at least one sub-slot in a downlink portion of a static slot in each repetition of the frame structure.
