  • Publication number: 20190223217
    Abstract: Embodiments provide for improving fairness among devices accessing a radio bandwidth, the devices including a mobile device using the radio bandwidth to access a radio access system using a channel access protocol, wherein the channel access protocol is a collision avoidance-type channel access protocol configured for using a back-off time before transmitting a retransmission (e.g., CSMA). Embodiments determine information from the radio bandwidth, where the information comprises inter-system packet transmission information; analyze the inter-system packet transmission information to determine an adjusted back-off time; and implement, by a mobile device, the adjusted back¬off time before transmitting the retransmission over the radio bandwidth.

  • Patent number: 10348465
    Abstract: A cellular multiple-input and multiple-output, MIMO, system comprises a base station having a plurality of antennas. Pilot signals are received by the base station in each frame of a sequence of frames (60). The base station analyzes the pilot signals to determine radio channel properties of radio channels between respectively each one of a plurality of terminals and the base station. The sequence of frames (60) comprises frames of a first frame type (61, 63, 64, 68) and frames of a second frame type (62, 69). Each frame of the second frame type (62, 69) have a greater number of time slots in which the base station receives the pilot signals than each frame of the first frame type (61, 63, 64, 68). The frames of the second frame type (62, 69) are included periodically in the sequence of frames (60).
