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: Systems, methods, and processing nodes for minimizing interference caused by high-powered wireless devices to other wireless devices in the network by determining an increase in a number of high-powered wireless devices attached to a serving access node causing a corresponding increase in a potential interference to standard-powered wireless devices attached to the serving access node. In response to determining this increase, the methods include activating a coordinated transmission mode for one or more standard-powered wireless devices.

Abstract: Systems and methods are described for selecting User Equipment(s) (UEs) for pairing in a cellular network. A channel orthogonality of one or more UEs may be determined at an Access Node (AN) for a condition. The one or more UEs may be inspected for a criteria. At least one of the one or more UEs whose data content meets the criteria may be scheduled with at least one other UE for Uplink (UL) Multi-User Multiple-Input-Multiple-Output (MU-MIMO) pairing.

Abstract: Systems and methods are described for donor access node (DeNB) selection at a relay access node (AN). A plurality of DeNBs may be identified, the DeNBs being located within a radio range of the relay AN. A metric may be calculated at the relay AN and used by the relay AN to select multiple, preferred DeNBs from the plurality of DeNBs. The relay AN may simultaneously request a connection to each of the multiple, preferred DeNBs. Data signals may be combined for transport at the relay AN and sent to end-user wireless devices, the multiple, preferred DeNBs, or both.

Abstract: Systems and methods are described for reducing latency for a group call. A group call random access (RACH) preamble selected from a subset of predetermined random access preambles associated with a group call may be received at an access node from a first wireless device, wherein the group call random access preamble indicates to the access node that a group call is to be established. A RACH response may be transmitted to the first wireless device comprising an uplink resource grant associated with a group call setup, wherein the uplink resource grant is greater than uplink resource grant associated with a default RACH response. And the group call may be established by communicating with the first wireless device based on the uplink resource grant associated with group call setup, wherein the group call is established between at least the first wireless device and a second wireless device.

Abstract: A control element of a first wireless communication network, such as a mobility management entity, determines that a wireless device is being served by a second wireless communication network. The control element also receives an indicator associated with the availability of a base station in the first wireless communication network to serve the wireless device. Based on the indicator, the control element initiates a handover of the wireless device from the second wireless communication network to the first wireless communication network. The control element may also initiates a handover of the wireless device based on the indicator and based on a signal strength reported by the wireless device.

Abstract: A method for donor selection in a relay access node includes identifying a plurality of candidate donor access nodes and obtaining one or more characteristics associated with each of the plurality of candidate donor access nodes. The method further includes determining a primary donor access node based on a comparison of the one or more characteristics between each of the plurality of candidate donor access nodes, and receiving a reference signal transmitted by the primary donor access node at a transmission power higher than a transmission power of downlink information transmitted by the primary donor access node. One or more quality characteristics of the primary donor access node are evaluated, and based on the one or more quality characteristics meeting a predetermined threshold, a connection to the primary donor access node is requested. Devices and systems relate to donor selection.

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.
