Abstract: Controlling the uplink transmission power includes dynamically activating and deactivating a high-power transmission mode of the wireless devices in response to changes in a network topology, such as presence or absence of different types of access nodes, and signal level measurements of reference signals transmitted from said different types of access nodes. Such dynamic control of the uplink transmission power in real time minimizes interference that may be caused to uplink transmissions of other wireless devices in the network, and mitigates unnecessary power consumption for wireless devices capable of utilizing the high-power mode.

Abstract: A relay node is enabled to transmit, to an end-user wireless device, any data packets remaining in a buffer associated with the end-user wireless device, prior to executing a handover of the end-user wireless device. Upon initiating a handover, the relay node adjusts a scheduling operation to use a lowest-possible modulating coding scheme (MCS) in order to transmit the remaining buffered data to the end-user wireless device. Moreover, the scheduling operation is adjusted to ignore any subsequent channel quality indicator (CQI) reports from the end-user wireless device, thereby ensuring that the end-user wireless device has a higher chance of receiving the data. When the buffer is empty, the handover is executed.

Abstract: Adjusting handover thresholds includes identifying a channel bandwidth of a first carrier deployed by an access node, wherein the first carrier is one of at least two carriers deployed by the access node and, for a wireless device attached to a second carrier deployed by the access node, adjusting a handover threshold based on the channel bandwidth of the first carrier, and/or the frame configuration deployed by the second carrier. The wireless device is assigned to a high power class and capable of operating in a carrier aggregation mode utilizing the first and second carriers.

Abstract: Systems and methods are described for assigning wireless resources to a high power wireless device. In some embodiments, a quality of service metric used for communication between a wireless device and an access node is identified, wherein the wireless device is configured to transmit an uplink signal at a first signal level that meets a power criteria. Default uplink resource are assigned to the wireless device based on the identified quality of service criteria, wherein the default uplink resources are associated with a default wireless device configured to transmit an uplink signal at a second signal level that does not meet the power criteria. And uplink communication is received at the access node from the wireless device using the assigned default uplink resources.

Abstract: A relay wireless device is configured to function as a relay on behalf of a donor access node. The relay wireless device determines a preferred donor access node from among a plurality of candidate donor access nodes based on a measurement of a reference signal, such as an RSRP or SINR, associated with each access node within a range of the relay wireless device. The access nodes may be prioritized based on the measurement, as well as based on a maximum number of dedicated random access preambles provided by each access node, and a default paging cycle of each access node. The access node that has the highest priority based on a good RSRP/SINR, a high number of dedicated random access preambles, and a large paging cycle, is selected as the preferred donor access node, and a connection request submitted to the preferred donor access node.

Abstract: Upon a determination that a relay backhaul link of a relay node is using excessive resources of a donor access node, wireless devices attached to the relay node are offloaded to other access nodes such as neighbor access nodes or to a different frequency band deployed by the donor access node or its neighbors. A donor access node transmits a congestion indicator to the relay node. The relay node transmits updated measurement parameters to end-user wireless devices connected thereto. An end-user wireless device reports back to the relay node in the event it measures a signal strength that is stronger than the current signal strength. This measurement event triggers a handoff of the end-user wireless device, thereby helping to alleviate the resource utilization of the air-interface of the donor access node.

Abstract: Systems and methods are described for performing a handover based on a target configuration. Signal information may be received, from a wireless device at a first access node, comprising a signal level for a received signal at the wireless device for a target frequency band, wherein the wireless device and the access node communicate over a source frequency band using a first subframe configuration. A second subframe configuration used by the target carrier to communicate with wireless devices may be determined. A traffic metric for the wireless device may be compared to the second subframe configuration. And, the wireless device may be instructed to perform a handover from the source frequency band to the target frequency band when the signal level meets a signal level criteria and the second subframe configuration satisfies the traffic metric.
