摘要： 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.

摘要： A technology for a user equipment (UE) is disclosed that is operable in an anchor-booster architecture of a multiple radio access technology (multi-RAT) heterogeneous network (HetNet). Control information to an anchor cell can be transmitted from a wireless wide area network (WWAN) node in the multi-RAT UE. Data packets of the multi-RAT UE can be selected for transmission via one of the WWAN node and a wireless local area network (WLAN) node in the multi-RAT UE using a multi-RAT coordination function (MRCF) module. Each data packet from one of the WWAN node and the WLAN cell can be transmitted to a multi-RAT small cell evolved node B (SC-eNode B) based on the selection by the MRCF module.

摘要： 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.
