Abstract: Methods and systems are described that incorporate joint network assisted offloading and cross-RAT (Radio Access Technology) user mapping techniques for integrated multi-RAT Het-Nets. Techniques are described for network based offloading and user association methods for multi-tier, multi-RAT HetNets, which account for overall user as well as network utility.

Abstract: A system provides dynamic interference avoidance in integrated multi-radio access technology (RAT) heterogeneous networks (Het-Nets). A multi-mode user equipment accesses mobile communications services using RATs. An integrated node provides a primary cell and at least one secondary ceil to the multi-mode user equipment. Initial radio access technologies (RATs) are assigned to the multi-mode user equipment from among a plurality of RATs for use by the multi-mode user equipment. Quality metrics are collected across the plurality of RATs. RAT assignments are re-evaluated based on the collected quality metrics. To provide dynamic interference mitigation in muiti-RAT Het-Nets, RAT assignments are periodically repartitioned from among the plurality of RATs for use by the multi-mode user equipment based on the re-evaluation of RAT assignments using the collected quality metrics.

Abstract: Some demonstrative embodiments include devices, systems and/or cellular network communications corresponding to a non-cellular network. For example, an Evolved Node B (eNB) may be configured to transmit to a User Equipment (UE) at least one configuration message to configure one or more measurements to be performed by the UE with respect to at least Wireless-Local-Area-Network (WLAN), to receive from the UE at least one report message including measurement information corresponding to the WLAN, to trigger the UE to start or stop offloading to the WLAN, and/or to transmit to the UE network assistance information corresponding to the WLAN.

Abstract: Embodiments of a base station and method for reducing asynchronous interference in a multi-tier OFDMA overlay network are generally described herein. In some embodiments, a lower-tier base station is configured to adjust OFDMA frame boundaries to cause frames communicated by a higher-tier to arrive within a cyclic prefix at the lower-tier base station. The lower-tier base station may also be configured to adjust OFDMA frame boundaries to cause frames communicated by a lower-tier of the network to arrive within a cyclic prefix at a higher-tier mobile station. Accordingly, frames from one tier may arrive within the cyclic prefix of another thereby reducing asynchronous interference.

Abstract: One of at least two available radio access technologies may be selected for a given radio communication. For example, quality of service or network loading may be used to make the selection.

Abstract: Methods and devices for optimizing on-time throughput in a wireless network. An enhanced node B (eNodeB) integrating two or more air interfaces schedules transmissions, for a measurement period, over at least one of the two or more air interfaces. The eNodeB estimates, based on the transmissions, a metric of on-time throughput for the user equipment (UE) within the cell, where on-time throughput is a measure of an amount of data that arrives at a destination before a delay threshold has been reached and at a bit-rate greater than or equal to a target bit-rate. The eNodeB then assigns UEs within the cell to an air interface of the two or more air interface to maximize the metric of on-time throughput for the UEs within the cell.

Abstract: A method and apparatus to manage interference in a multi-cellular network is disclosed. This approach uses downlink power control to allow a serving femto access point of a plurality of femto access points to transmit signals at a first power level to ensure a quality of service level of a service provided to a first plurality of mobile stations served by the plurality of femto access points. This approach also uses the downlink power control to adjust a power level of the signals transmitted by a serving femto access point of the plurality of the femto access points to manage interference caused by the serving femto access point on a second plurality of mobile stations served by one or more macro base stations.

Abstract: In some embodiments, a femto access point comprises a baseband processor, an RF modulator/demodulator coupled to the baseband processor to modulate/demodulate data for communication within a predetermined frequency range, one or more antennas to coupled to the RF modulator/demodulator to transceive information with one or more wireless devices via a wireless communication link, and a control module to implement a femto transmission-free zone in at least one of a time domain or a frequency domain and in which the femto access point does not transmit data. Other embodiments may be described.
