Abstract: One or more packets to be transmitted to or from a user equipment (UE) device are determined to have a particular packet length, e.g., based on a vocoder to be used for a voice over Long Term Evolution (VoLTE) call. An initial modulation and coding scheme (MCS) is selected for transmission of the packets based on channel conditions. The initial MCS is replaced by an alternative MCS having a lower efficiency than the initial MCS in response to a determination that the alternative MCS would require the same number of resource blocks to transmit a packet having the particular packet length as the initial MCS. One or more resource blocks are allocated for transmission of the one or more packets having the particular packet length using the alternative MCS. Indications of the allocated one or more resource blocks and the alternative MCS are transmitted to the UE.

Abstract: Systems and methods are described for performing a group call using a data bearer. At a core network in communication with an access node, a request to establish a group call may be received. A multicast data bearer may be established with the access node such that group call data from the core network is communicated over the multicast data bearer to the access node. Group call data may be communicated between the access node and a first wireless device and the access node and a second wireless device, wherein downlink group call data from the core network for both the first wireless device and the second wireless device is transmitted to the access node over the multicast data bearer.

Abstract: Disclosed are methods and systems for managing allocation of air interface resources to a relay user equipment device (relay-UE) that provides wireless backhaul connectivity for a relay base station (relay-BS). In particular, a base station may serve the relay-UE and may make a determination that the relay-UE is positioned within an indoor environment rather than within an outdoor environment. While serving the relay-UE, the base station may manage allocation of air interface resources to the relay-UE and may do so based at least on the determination that the relay-UE is positioned within an indoor environment rather than within an outdoor environment.

Abstract: Systems and methods are described for handoff of a wireless device. A total delay budget may be configured to a first access node. Scheduler delays associated with each of multiple scheduling buffers can be measured. An average scheduling delay for multiple wireless devices may be calculated based on the measured scheduler delays. The average scheduling delay may be compared to the total delay budget for the first access node and, when the average scheduling delay exceeds the total delay budget, a second access node may be selected for offload of at least one wireless device of the multiple wireless devices.

Abstract: A method and system for controlling application of MU-MIMO. The disclosure provides for considering the quantity of data buffered for transmission over the air between the base station and each of various UEs, and selecting UEs to be subject to MU-MIMO service based on the quantity of data buffered. For example, a base station could prefer application of MU-MIMO for UEs that have more data buffered for transmission than other UEs. Or the base station could condition application of MU-MIMO to a pair of UEs on a determination that each UE of the pair has at least a threshold quantity of data buffered for transmission.

Abstract: Systems and methods are described for mitigating interference from neighbors. Interference may be monitored at a first access node, wherein the monitoring includes detecting an interference pattern over at least two monitored subframes. The interference pattern may be analyzed to identify one or more interference sources, wherein a first interference pattern indicates interference caused by a neighboring access node and a second interference pattern indicates interference caused by one or more wireless devices communicating with a neighboring access node. The identified interference sources may be instructed to adjust transmissions based on the monitored interference.

Abstract: Reducing latency in a wireless network includes initiating a sensing period for measuring signal indicators of a plurality of frequency channels of an unlicensed spectrum, determining that one of the plurality of frequency channels is able to sustain a traffic load, interrupting the sensing period, and scheduling one or more cellular subframes during the remainder of the sensing period using the one of the plurality of frequency channels.

Abstract: Systems and methods are described for scheduling transmissions from an access node in a communication network. A plurality of data packets may be received at a buffer of an access node. A discard timer may be started on receipt of the data packets. When the discard packet timer expires, a number of data packets in the buffer and an associated aggregated queuing delay may be determined. The aggregated queuing delay may be compared to target block error rate (BLER). The target BLER may be modified when the aggregated queuing delay and the number of data packets exceed a target threshold. Data packets may be transmitted from the access node using the modified BLER.

Abstract: A method and system to help facilitate efficient use of frequency spectrum. A base station will provide service on two carriers that partially overlap with each other in frequency. To facilitate this, the base station could shift the frame timing of one carrier in relation to the other carrier, so as to minimize or avoid overlap of the carriers' downlink control channels. Further, the base station could control service on each carrier in a manner that helps avoid resource conflicts within the overlapping frequency region.
