摘要： Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.

摘要： This disclosure describes techniques for scheduling distribution of content to a plurality of devices in a communication network, such as a cellular-based wireless network. According to this disclosure, two or more distribution techniques may be used, and scheduling techniques are performed to determine which distribution technique to use for different content. For example, content can be broadcast to all devices on the network (broadcast), multicast within several cells of the network (multi-cell multicast), multicast in a specific cell of the network (single cell multicast), or unicast to one or more specific devices within specific cells of the network (unicast). The scheduling techniques described in this disclosure may improve content distribution by substantially maximizing the number of content requests that are satisfied, particularly when bandwidth is limited.

摘要： Methods, apparatuses, and computer program products are disclosed for facilitating a beacon-assisted handover from a macro network to a femto cell during an active call. A femto cell management system assigns a unique identifier to a femto cell, which the femto cell utilizes to broadcast a beacon at a frequency different than the operating frequency of the femto cell. A wireless terminal receives a control message from the macro network directing the wireless terminal to scan particular frequencies. The wireless terminal subsequently provides a report to the macro network identifying attributes ascertained from the scan, which includes attributes associated with the beacon. The macro network then performs a handover from the macro network to the femto cell as a function of the attributes.

摘要： Methods and apparatuses are provided that include classifying nearby devices as neighboring or non-neighboring devices. Devices can be classified based on detected registration attempts to a femto node, where the femto node can switch paging area identifiers to cause the registration attempts or otherwise, analyzing measurement reports received from the devices in a registration request, and/or the like. The femto node can mitigate interference to the devices based on the classification.

摘要： A multi-mode access point supports different radio access technologies (e.g., Wi-Fi and cellular) for serving multi-mode access terminals. To provide improved service for such an access terminal, the access point may redirect the access terminal from a first type of radio access technology to a second type of radio access technology under certain circumstances. A decision to invoke such a redirection may be based on, for example, at least one of: traffic conditions on the first type of radio access technology, traffic conditions on the second type of radio access technology, and whether a backhaul for the access point is currently a bottleneck for access point communication.

摘要： Methods and apparatuses are provided that include calibrating transmit power of a femto node based on measuring one or more parameters related to usage of the femto node. The femto node can temporarily increase transmit power and analyze received measurement reports to determine a transmit power calibration. The femto node can additionally measure uplink received signal strength indicators over multiple time periods following handover of a user equipment (UE) to determine whether to increase transmit power to cover the UE.

摘要： Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.
