Abstract:
PROBLEM TO BE SOLVED: To provide a method for adaptive server selection in a wireless communication. SOLUTION: 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. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE), served by a cell of a base station, may identify a time division duplexing (TDD) configuration for a first cell, wherein the TDD configuration includes a symbol pattern for a slot. The base station may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a TDD configuration. A first UE may receive a configuration for transmitting a cross-link interference (CLI) sounding reference signal (SRS) to a second UE according to the configuration. The second UE may measure the CLI SRS and report the measurement.
Abstract:
Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.
Abstract:
A method an apparatus and a computer program product for wireless communication are provided in connection with determining whether to offload a device from a femto node. In one example a serving femto node is equipped to obtain load information regarding a target node compare an expected throughput at the target node estimated based in part on the load information to a threshold and determine whether to handover a device to the target node based in part on the comparing. In an aspect the serving node is further equipped to compute its own throughput based on parameters specific to the serving femto node or the device and the threshold is the throughput at the serving femto node.
Abstract:
Transmit power for a user equipment (UE) is set by a Home NodeB (HNB) in response to interference at a nearby macrocell. The HNB monitors an interference level to the macrocell from a UE communicating with the HNB. An acceptable transmit power for the UE is determined by the HNB in response to the interference level. A power change indicator is transmitted from the HNB to the UE to adjust the transmit power of the UE. In some cases, the interference may be estimated from a busy indicator from the macrocell and the HNB sends a modified version of the busy indicator to the UE to adjust the transmit power of the UE. In other cases, the HNB estimates a path loss for the UE based on received signal power from the macrocell and signals a transmit power change to the UE, if needed, based on the estimated path loss.

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 eac h 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 no n- serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the acces s 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, there by allowing the service outage associated with server switching to be substantially reduced.
Abstract:
Methods, systems, and devices for wireless communications are described According to one or more aspects of the present disclosure, a user equipment (UE) may receive an uplink grant of an uplink transmission from the UE to the base station. The UE may identify a packet transmission mode indicated in the uplink grant. The indication may specify whether the UE is to transmit the uplink transmission using a default mode, such as a first-in first-out mode, or a packet-group transmission mode. The UE may determine packets for inclusion in a transmission payload for the uplink transmission based on the identified transmission mode and transmit the uplink transmission in accordance with the packet transmission mode and the uplink grant.
Abstract:
Apparatus and methods for managing a load in a network of femto nodes are described herein. One or more parameters corresponding to a resource load on a femto node may be detected. The power of the femto node may be adjusted based on the one or more parameters to decrease a resource load on the femto node. One or more other femto nodes may then be notified of the power adjustment.
Abstract:
Methods and apparatus are provided for adapting femtocell properties based on changes detected in network topology. A method includes detecting a network topology change associated with a network node. The method includes determining an availability factor of the network node based on the topology change. The method includes setting mobility parameters of at least one mobile entity serviced by the network entity and mitigating interference with at least one neighboring network node based at least in part on the network topology and on at least one adjusted resource parameter of the network entity.
