Abstract: Systems and methods are described for selecting a wireless device to share a set of resource blocks from an access node. A channel orthogonality of a plurality of parallel data streams received at the access node from wireless devices may be determined. From the wireless devices, a non-relay capable wireless device whose channel orthogonality meets a set threshold may be selected. From the plurality of wireless devices, a relay-capable wireless device whose channel orthogonality meets a set threshold may be selected. The selected non-relay capable and relay-capable wireless devices may be paired to share a same set of resource blocks. The selected non-relay capable and relay-capable wireless devices may be scheduled for resource transmission.

Abstract: When a UE is served by a first RAN and engages in signaling via the first RAN with a second RAN for the second RAN serve the UE with a call (e.g., in a circuit-switched fallback process), the second RAN will determine a speed of movement of the UE and will decide based on the speed of movement whether to provide the UE with a second-RAN traffic channel assignment in addition to providing the UE with an indication of second-RAN coverage in which the call will be served. For instance, if the UE is moving at a threshold high rate of speed, then the entity will provide the UE with a second-RAN traffic channel assignment so as to help expedite the start of the call and to help avoid an issue where the UE may move out of the second-RAN coverage in which the call is to be served.

Abstract: Systems and methods are described for implicit information transfer. Neighboring access nodes may coordinate an Almost Blank Subframe (ABS) pattern for ABS transmissions. Implicit transmit symbols may be assigned to ABS′ of the ABS pattern. Traffic may be scheduled for a wireless device on at least one ABS of the ABS pattern. The neighboring access nodes may use the scheduled ABS to decode implicit information associated with the implicit transmit symbols.

Abstract: Disclosed herein are methods and systems for selection of a coordinated multipoint (CoMP) mode for a relay base station, based on traffic load being experienced between the relay WCD and donor base station that provide the relay tunnel used by the relay base station for backhaul communication. An exemplary method involves the relay base station: (i) determining a load indication for a communication link between a relay wireless communication device (WCD) and a donor base station, (ii) using the load indication for the communication interface between the relay WCD and the donor base station as a basis for selecting a CoMP mode from a plurality of available CoMP modes; and (iii) providing wireless service in at least one coverage area according to the selected CoMP mode.

Abstract: Disclosed herein are methods and systems for dynamically controlling bearer quality-of-service (QoS) configuration. In an example arrangement, a wireless communication device (WCD) may have a first bearer and a second bearer with a base station, where the first bearer has a first set of one or more QoS parameters defining a first priority level for the base station scheduling communications on the first bearer, and the second bearer has a second set of one or more QoS parameters defining a second priority level for the base station scheduling communications on the second bearer, the second priority level being different from the first priority level. In this arrangement, an example method may involve detecting that the base station is threshold highly loaded, and responsive to the detecting, reconfiguring the second bearer to have the same QoS parameters as the first set of one or more QoS parameters.

Abstract: Disclosed is a method and system for selectively muting default downlink transmission of particular reference signals in order to reduce interference experienced by user equipment devices (UEs) receiving user data. In scheduling transmission of a downlink resource block (RB), a base station may select a particular transmission mode (TM) that does not require transmission of the particular reference signal. The base station may also determine that no condition exists that requires default transmission of the particular reference signal during a time interval allocated for transmission of the RB and on sub-carrier frequencies allocated to the RB. With particular TM selected and the absence of other requirements for default transmission of the particular reference signal, the base station can then mute transmission of the particular reference signal during transmission of the downlink RB. The base station may also coordinate scheduling with a neighboring base station to achieve further interference reduction.

Abstract: A method and system to help control air interface resource allocation. A base station monitors for each served UE a ratio of physical resource block (PRB) allocation to queued data, as a PRB/data ratio. The base station then detects that the PRB/data ratio of a first served UE has been threshold lower than the PRB/data ratio of each of a plurality of second served UEs, and the base station responsively selects at least one of the second UEs based on its modulation and coding scheme (MCS) being relatively high, and the base station limits PRB allocation to the selected UE to help reduce its PRB/data ratio and to thereby help achieve a level of fairness in PRB allocation.

Abstract: Systems and methods are described for improving capacity of voice services for data packet transmission through a wireless network. Application requirements including a data rate for a wireless device may be determined. An access node may determine available resources to transmit data as indicated by the application requirements. The wireless device and the access node may communicate data transmissions wirelessly for use by the wireless device application. Data transmission may be in a first mode or in a second mode depending whether there are sufficient available network resources for the determined data rate. The first and second transmission modes may be generated from a common input such as a wireless device user's voice; however, the second mode of data transmission may be converted in order to consume less network resources.

Abstract: Dynamically selecting a frame configuration as depicted herein includes determining a number of wireless devices within the wireless network that are capable of multiple transmissions using a first frame configuration comprising a first ratio of uplink subframes relative to downlink subframes, comparing the number with a threshold, and selecting a second frame configuration for each of the number of wireless devices based on the comparison. The second frame configuration comprises a second ratio of uplink subframes relative to downlink subframes that is different from the first ratio.

Abstract: Systems and methods are described for performing handover of a wireless device to a target Access Node (AN) sector. Beam-form capable sectors of one or more target ANs may be selected from a pool of candidate sectors. At least one of the selected sectors may be prioritized (e.g., over the other sectors) based on an open beam-form seat. Handover of the wireless device from a first AN to the prioritized sector may be performed.
