Abstract: Techniques are described for wireless communication at a wireless communication device. One method includes obtaining a plurality of signal strength samples for a first wireless channel during a measurement period; determining a loading parameter of the first wireless channel based at least in part on a distribution of the signal strength samples for the first wireless channel among a set of predefined signal strength bins; and selecting a wireless operating channel based at least in part on the determined loading parameter of the first wireless channel.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station operating in unlicensed spectrum may temporarily increase a paging opportunity window (POW) size, or reduce a time between POWs, in order to meet performance metrics or account for time periods when a base station is unable to win access to the wireless medium during a POW. In some cases, a UE may identify a failed listen-before-talk procedure and autonomously update the POW size. In other examples, a base station may initiate a change in POW size or increase a number of paging opportunities in order to meet achieve one or more key performance indicators (KPIs). After a predetermined period, or after a triggering condition is no longer present, the UE and the base station may reset the POW size or the number of paging opportunities to a nominal amount to conserve power.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor for discovery reference signal (DRS) transmissions, physical downlink shared channel (PDSCH) transmissions, or combinations thereof within a DRS transmission window. The UE may attempt to decode DRS or PDSCH transmissions for a subframe based on detection of DRS transmissions, prioritization of DRS transmissions relative to PDSCH transmissions, locations of subframes within a radio frame, overlapping of the DRS transmission window with a paging opportunity, or any combination thereof. In some cases, one or more radio link monitoring (RLM) parameters may be adjusted based on decoding of PDSCH or DRS transmissions.

Abstract: Techniques are described for selected internet protocol traffic offload (SIPTO) support at an assisting eNodeB. A connection may be established between a first eNodeB and a UE, and it may be determined whether a connection exists or is pending between the UE and a second eNodeB. A message may be transmitted to a mobility management entity (MME), the message associating a network address of the second eNodeB with SIPTO connectivity for the UE.

Abstract: Detecting local cell identifier collision by a base station may be achieved by receiving, at a first base station from a user device, a dedicated identifier associated with a second base station. The dedicated identifier may include or otherwise map to a user device identifier associated with the second base station and a local cell identifier associated with the second base station. Based on the dedicated identifier, it may be determined, at the first base station, that there is a local cell identifier collision between the first base station and the second base station.

Abstract: Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements.

Abstract: According to some wireless network standards the size of a neighbor cell list is restricted to a maximum size. The limited size of a neighbor cell list may not reflect the realities of a wireless network deployment, especially for deployments including numerous femto cells clustered in close proximity. Accordingly, as the concentration of macro cells and/or femto cells in an area increases, there lies a challenge to identify and communicate neighbor lists to user devices that reflect the arrangement of a particular portion of the deployment and the needs of the user devices. Various systems, methods and apparatus described herein are configured to provide a user device or a group of user devices a neighbor cell list that includes neighbor cell identifiers chosen from a candidate list.

Abstract: Techniques for switching user equipments (UEs) between wireless systems are disclosed. A UE may be located within the coverage of a plurality of wireless systems and may communicate with a first wireless system among the plurality of wireless systems. The plurality of wireless systems may include a WLAN system and a cellular system and/or may be part of a small cell. Metrics of the UE for the plurality of wireless systems may be determined. The metrics may be related to one or more of efficiency, service charge, service subscription, application type, or buffer size. Whether to switch the UE from the first wireless system to another wireless system may be determined based on the metrics. In one design, switching priorities of the UE for the plurality of wireless systems may be determined based on the metrics and may be used to determine whether to switch the UE.
