    Abstract: A communication system where wireless devices communicating with an access node may be communicating either directly with the access node, or via a heterodyne repeater. A heterodyne repeater relays communications transparently such that operation of the access node may not provide the ability to distinguish which wireless devices are communicating directly from those that are communicating via the heterodyne repeater. The system determines whether the wireless device is communicating either directly with the access node, or via a heterodyne repeater. When a wireless device is communicating via a heterodyne repeater, the access node selects a radio resource control configuration adapted for communication via a heterodyne repeater to be used with that wireless device.

    Abstract: Systems and methods are described for configuring a delay based scheduler for an access node. A plurality of packets may be received at an access node, where at least a first packet is associated with an application running on a wireless device in communication with the access node. The plurality of packets may be inspected to determine that one or more of the packets associated with the application are marked, where the mark indicates network congestion. A remaining time for the first packet may be calculated based on a packet delay budget associated with the running application and the determination that one or more of the packets associated with the application are marked. The first packet may then be scheduled for transmission to the wireless device, using a delay based scheduler, based on the calculated remaining time.

    Abstract: Systems and methods are described for configuring a scheduler at an access node. At least two regions may be determined for a coverage area of an access node, wherein a first region is bounded by a first distance from the access node and a second region is bounded by a second distance from the access node such that the second distance is greater than the first distance. Wireless transmissions may be scheduled from the access node based on a fairness algorithm such that the fairness algorithm schedules wireless transmissions to wireless devices associated with the first region based on throughput for the wireless devices associated with the first region and the fairness algorithm schedules wireless transmissions to wireless devices associated with the second region based on throughput for wireless devices associated with the second region.

    Abstract: A transmit power level of a wireless device is adjusted based on an uplink interference to neighboring sectors caused by the transmit power level. The wireless device can estimate the uplink interference using a reference signal transmitted by each neighboring sector. The uplink interference is based on a loss of signal strength of the reference signal as measured at the wireless device, i.e. a path loss. A determination is made to adjust the transmit power level of the wireless device so as to improve a coverage area of the serving sector, without generating excessive interference in neighboring sectors. Consequently, a transmit power level increase is based on a function of the data demand of the wireless device, the interference caused to neighbors, and the load on neighboring sectors.
