Methods, systems and devices to improve channel utilization
A method that incorporates aspects of the subject disclosure may include, for example, obtaining, by a system comprising a processor, interference information associated with one or more physical resource blocks (PRBs) from each base station of a plurality of base stations. Further, the method can include determining, by the system, from the interference information a strategy for improving a PRB utilization of a first base station of the plurality of base stations. In addition, the method can include conveying, by the system, the strategy to at least one base station of the plurality of base stations. Other embodiments are disclosed.
Techniques for enhanced coverage semi-persistent scheduling
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a unicast channel for a first downlink transmission from a base station using a first semi-persistent scheduling (SPS) configuration. The UE may receive downlink control information (DCI) from the base station indicating a second SPS configuration associated with a different coverage level than the first SPS configuration. In some cases, the DCI may be DCI that is common to a set of UEs. Here, the DCI may indicate the second SPS configuration and the UE may identify a set of parameters associated with the second SPS configuration based on a radio resource control (RRC) message received prior to the DCI. Based on receiving the indication of the second SPS configuration, the UE may monitor the unicast channel for a second downlink transmission from the base station using the second SPS configuration.

Joint scheduling of device-to-device (D2D) links and wide area network (WAN) uplink (UL) user equipments (UEs)
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus of a device-to-device (D2D) link receives from a base station an indication of an acceptable level of interference that the base station can tolerate on an uplink resource. The uplink resource is allocated to a user equipment (UE) for a wide area network (WAN) transmission. The acceptable level of interference is a level of interference that the base station can tolerate on the uplink resource while the base station receives the WAN transmission from the UE. The apparatus determines a level of interference to the UE's transmission at the base station and performs a D2D communication on the uplink resource allocated to the second UE for the WAN transmission if the determined level of interference is less than the acceptable level.

Program for adjusting channel interference between access points in a wireless network
The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
Apparatus, Systems and Methods for System Selection and Reselection
Described herein are apparatus, systems and methods for opportunistic system selection and reselection to avoid jammer desense intermodulation distortion. A method may comprise, at a user equipment (“UE”), identifying a list of frequencies and bands available to a cellular modem of the UE for one of system selection and system reselection, identifying a subset of the list of frequencies and bands based on an operation of a non-cellular wireless communication component of the UE, storing the subset of the list of frequencies and bands in a graylist, and performing, by the cellular modem, a search for one of the system selection and the system reselection based on the graylist.

Methods and systems for in-device interference mitigation
Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an “out of synch’ counter and/or the radio link failure (RLF) timer used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.
Frequency agility for an ISM band home area network
Due to interference that typically occurs in the ISM band, it may be necessary for one or more network devices to switch to an alternative channel. A list of one or more alternate network channels may be generated by a coordinating/gateway device based on the energy level and a distance from a primary network channel. The alternate network channel list may be distributed to neighbor devices and, in the event of interference, link loss, and/or a channel switch notification, the neighbor devices may automatically switch to the first alternate network channel in the list.
