Abstract: Device-to-device (D2D) contention management systems and methods provide managed offloading of cellular network traffic through a contention-based network. For each link in a group of links between nodes in the contention-based network, a link cost is calculated to determine a number of potential links that may interfere with the link, if activated. Each link is evaluated in the order of ascending link cost to determine whether it complies with predefined conditions and whether activating the link increases or decreases D2D network throughput. If the link increases throughput, the link is activated.

Abstract: Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for opportunistically transitioning service flows of mobile devices between being direct and indirect. In various embodiments, a proximity between first and second mobile devices that are in wireless communication with each other may be monitored. In various embodiments, a selective transition of a service flow between the first and second mobile devices from being indirect through the radio network access node using a first radio access technology (“RAT”) to being direct using a second RAT may be facilitated, e.g., responsive to a determination that a first criterion has been met. In various embodiments, a selective transition of the service flow from being direct using the second RAT to being indirect using the first RAT may be facilitated, e.g., responsive to a determination that a second criterion has been met.

Abstract: A base station and method include dividing machine to machine devices into a plurality of groups and paging each group during paging listening windows corresponding to each paging group during a coordinated paging cycle. A machine to machine device wakes up at a coordinated paging cycle selected from a number of coordinated paging cycles and sends uplink data following receipt of the number of coordinated paging cycles corresponding to the reporting period.

Abstract: A method and apparatus to manage interference in a multi-cellular network is disclosed. This approach uses downlink power control to allow a serving femto access point of a plurality of femto access points to transmit signals at a first power level to ensure a quality of service level of a service provided to a first plurality of mobile stations served by the plurality of femto access points. This approach also uses the downlink power control to adjust a power level of the signals transmitted by a serving femto access point of the plurality of the femto access points to manage interference caused by the serving femto access point on a second plurality of mobile stations served by one or more macro base stations.

Abstract: FCH locations are mapped to preamble sequence sets to allow more than three stations to transmit their FCHs with minimized or reduced interference. A lower interference environment may be provided to transmit the FCH within each DL relay phase when the number of stations within the phase is less than the number (L) of distinct FCH locations. With more than L stations in a DL relay phase, a reduced interference environment for FCH transmission may be achieved by assigning the same FCH location to RSs that are far away from each other.
