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: A user equipment (UE) is configured to receive a maximum probability of accessing a wireless local area network (WLAN) for communication. The maximum probability is received via a 3rd Generation Partnership Project (3GPP) communication link with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE is further configured to determine that there is a queued transmission for the UE and, in response to determining that there is a queued transmission, to determine whether the UE is authorized to access to the WLAN using a probability less than or equal to the maximum probability. The UE is further configured to delay contention for access to the WLAN for at least a pre-backoff duration in response to determining that the UE is not authorized.

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.
