Abstract:
Interference that occurs during wireless communication may be managed by determination and application of an adaptive path loss adjustment. A method, apparatus and medium of communication determine a level of excess received interference based at least in part on out-of-cell interference (Ioc). The path loss is adjusted by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed stable communication.

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:
The present disclosure presents methods and apparatuses for improved paging area identifier selection in femto nodes and other low power base stations. In some examples described in the present disclosure a method is provided for selecting a paging area identifier at a low power base station which includes determining whether a neighboring high power base station is detectable. Additionally the method can include observing where the neighboring high power base station is detectable a broadcasted paging area identifier of the neighboring high power base station. Furthermore example methods may include selecting a paging area identifier of the low power base station to be the broadcasted paging area identifier and transmitting the paging area identifier.
Abstract:
The disclosure is related to selecting an operating channel for a cellular network to reduce interference to a wireless local area network (WLAN) operated by a small cell comprising a WLAN access point and a cellular network modem. The small cell performs a channel scan of available channels, determines whether or not there is a clean channel to be the operating channel for the cellular network based on the channel scan, wherein a clean channel comprises a channel that interferes with the WLAN less than a WLAN interference threshold, and selects the clean channel as the operating channel for the cellular network based on the clean channel being available or turns off the cellular network based on no clean channel being available.
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.
Abstract:
Un esquema de calibración de potencia ajusta los niveles de potencia de la red de femtoceldas basado en macro señales observadas en diferentes puntos en y alrededor de un área de cobertura y basado en las posiciones mutuas de las femtoceldas (p.ej., basado en señales de femtoceldas observadas en estos puntos). Por lo tanto, el esquema de calibración de potencia facilita un buen equilibrio entre proveer un nivel deseado de cobertura y mitigar la interferencia de macroceldas y femtoceldas cercanas.
Abstract:
Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. In an embodiment, an access terminal is 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 AT belong to different cells. The access terminal is further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC provides an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced. A method for handoff is further disclosed using DSC as early indication of handoff, which also trigger multitasking forward traffic for the access terminal to all access points.
