Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) operating in an unlicensed radio frequency spectrum band may transmit autonomously (e.g., without a resource assignment) to a base station. For example, a base station may indicate a periodic resource allocation to the UE using radio resource control (RRC) messaging. The UE may then perfonn a listen-before talk (LBT) procedure and transmit physical uplink control channel (PUCCH) or other messages using the periodic resource allocation. Thus, the UE may transmit uplink messages without receiving an assignment of uplink resources from the base station. The UE may transmit identification and synchronization information in a scheduling request (SR) resource of the autonomous PUCCH. For example, the UE may indicate a start time and duration of an autonomous uplink transmit opportunity (TxOP) using resources designated for SR transmission.

Abstract translation: 描述了用于无线通信的方法，系统和设备。 在无执照射频频谱带中操作的用户设备（UE）可以自主地（例如，不需要资源分配）向基站进行传送。 例如，基站可以使用无线电资源控制（RRC）消息向UE指示周期性资源分配。 UE然后可以执行先听后说话（LBT）过程并使用周期性资源分配来传送物理上行链路控制信道（PUCCH）或其他消息。 因此，UE可以在不从基站接收上行链路资源的指派的情况下发送上行链路消息。 UE可以在自治PUCCH的调度请求（SR）资源中发送标识和同步信息。 例如，UE可以使用为SR传输指定的资源来指示自主上行链路传输机会（TxOP）的开始时间和持续时间。

Abstract: Access terminals are provisioned to conduct intra - frequency, inter- frequency, and inter-RAT measurements and report physical layer identifiers of detected cells (106,108,110,112). The provisioning may involve cycling through all or a portion of a defined superset of physical layer identifier (PLI) one subset at a time. In addition, the physical layer identifiers (PLI) may be prioritized to improve the search procedure. Measurement report messages (MRMS) (including physical layer identifiers of the detected cells) are received at an access point (106) as a result of the provisioning. A neighbor cell list (118) for the femtocell is maintained based on the received measurement report messages (MRMS) and, optionally, other information. This other information may related to, for example, one or more of: physical layer identifier information (PLI) received from access terminals (104) that register with the access point, physical layer identifier information received via network listen operations (128), information regarding co-located cells (130), or physical layer identifier information received (134) from a network entity (114).

Abstract: Methods and apparatuses are provided for determining whether to handover a device to mitigate uplink interference while achieving acceptable uplink service quality in a wireless network. One or more parameters related to a device can be evaluated to determine whether to handover the device, such as a number of transmission power reports received from the device over a period of time, a frame error rate, setpoint, or power control commands related to the uplink of the device, a received pilot signal strength at the device, an uplink throughput or buffer size at the device, etc., from which transmit power information of the device can be inferred for determining whether the device potentially interferes with access points or devices. Based on the one or more parameters, an access point can determine whether handing over the device may mitigate such uplink interference while ensuring uplink service quality, and accordingly handover the device.
