  • Patent number: 8699411
    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.

  • Patent number: 8565138
    Abstract: A method of coordinating communications between a wireless MIMO base station and a plurality of wireless communication devices is disclosed. The method includes generating a series of index numbers for controlling sub-slot assignments for the plurality of wireless communication devices, providing data representing the series of numbers to the MIMO base station and each of the plurality of wireless communication devices, and controlling simultaneous communication between the plurality of wireless communication devices and the MIMO base station by reassigning access by the plurality of wireless communication devices to a plurality of sub-slots in a communication structure of unit size.

  • Patent number: 8559455
    Abstract: A computer-implemented method may include receiving, at the base station, an identification and request for transmission access from a wireless computing device, determining a level of efficiency for data communications between the base station and the wireless computing device, selecting a descriptor for the level of efficiency, from among a plurality of predetermined descriptors that identify discrete efficiency classifications across a range of efficiencies, determining a share of bandwidth for communication between the base station and the wireless computing device based on the selected descriptor, and communicating electronically with the wireless computing device using the selected share of bandwidth. A higher share of bandwidth may be selected for a wireless computing device having a higher determined level of efficiency.

  • Patent number: 8396086
    Abstract: A computer-implemented method may include receiving at a wireless device one or more beacon packets sent by a communication base station, determining a delay period at the wireless device, wherein the delay period is determined so that a delay for the wireless device is different than a delay for another wireless device, sending a first association request from the wireless device after waiting for the delay period, and establishing communication with the base station if an association response is received from the base station within a determined time period. The first association request may include information identifying the wireless device and an association code.
