摘要： Providing for fast allocation of additional carriers in multi-carrier wireless communication systems is described herein. By way of example, high layer protocols can be employed to allocate additional carriers to UEs in a wireless network. Additionally, management of the additional carriers can be accomplished via high speed lower layer signaling protocols. Management can involve activating/deactivating the additional carriers, instructing the UE to provide carrier feedback, monitor pilot or control channels of such carriers, or the like. Because lower layer signaling is relatively fast, activation or deactivation of the additional carrier can be quickly implemented in response to contemporaneous changes in channel conditions. Thus, changes to signal quality or network loading can be determined and utilized to customize carrier activation in near real-time, providing efficient resource allocation while conserving UE battery life.

摘要： Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.

摘要： Adaptive delay management means and method for allocating resources having different Quality of Service (QoS) requirements. A Forward Link (FL) scheduler prepares transmission instances by treating pending data queues according to a priority class, such as Best Effort (BE) and Expedited Forwarding (EF). Data bits from multiple queues are stuffed into a transmission instance. Various metrics are used to generate a set of candidates for transmission and then select and build a next transmission instance from the set of candidates.

摘要： Methods and apparatuses are provided for adjusting a scheduled load for one or more user equipment (UE) in a wireless network. A comparison of each of one or more control parameters related to signals received from one or more UEs to a corresponding threshold can be determined. The control parameters can correspond to an in-cell load, rise-over-thermal, etc. The scheduled load of a base station can be adjusted based in part on the comparison. This adjustment can include adjusting the scheduled load by a step-size increase value or step-size decrease value, which can be computed based in part on a target tail probability for the one or more control parameters.

摘要： Methods and apparatuses are provided that include deploying a femto node in a wireless network. The femto node can measure received signal quality upon initialization in a wireless network and/or according to a timing. The femto node can determine whether to communicate in the wireless network based on comparing the received signal quality to a threshold signal quality. The timing can be determined based on various factors to ensure fairness among femto nodes initializing in the wireless network. A centralized entity can be used to determine the timing and/or whether a femto node should communicate.

摘要： A location of an access terminal is estimated based on signals received by the access terminal. The manner in which a femto cell transmits signals and/or the manner in which the access terminal monitors for signals may be controlled in some cases to facilitate the reception of signals at the access terminal during a location determination operation. In some embodiments, the number of femto cells for which the access terminal monitors for signals may be controlled by controlling the manner in which the access terminal maintains its active set. In some embodiments, in the event a given femto cell is interfering with the ability of an access terminal to receive signals from other femto cells, that femto cell may be instructed to temporarily stop transmissions (e.g., on the traffic channel and/or a beacon channel).

The triggering algorithm includes instructions for the access terminal to report downlink measurements as a function of trigger events detected over the anchor carrier and/or the supplementary carrier. Downlink measurements taken by the access terminal are provided to the base station. Cell management instructions based in part on the downlink measurements are then provided to the access terminal by the base station.

摘要： Systems, methods, and devices are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile devices. An out-of-band (OOB) link is used to detect that a mobile device is in proximity of a femtocell. Having detected the mobile device in proximity to the femtocell, an OOB proximity detection is communicated to a femtocell gateway disposed in a core network in communication with the macro network to effectively pre-register the mobile device with the femto-convergence system. When the femtocell gateway receives a handover request from the macro network implicating the pre-registered mobile device, it is able to reliably determine the appropriate target femtocell to use for the hand-in according to the pre-registration, even where identification of the appropriate target femtocell would otherwise be unreliable. Some embodiments may also handling registering the mobile device after a handover request has occurred, including tiered approaches.
