    摘要: Disclosed herein are systems and methods that are directed to alleviating the hidden node problem occurring in wireless systems by using the simultaneous transmission and reception (STR) capability without increasing the medium access layer (MAC) overhead. Accordingly, a receiving device receiving a data packet from a transmitting device can simultaneously transmit a data packet, called a STR Clear to Send (CTS). This STR-CTS can create a guard zone around the receiving device to avoid collisions from unwanted transmissions from secondary devices, e.g., neighboring STAs and/or APs. In various embodiments, the STR-CTS packet transmitted by the receiving device can be decodable by legacy devices, e.g. legacy STAs and APs, as well as next generation devices, for example, those employing unlicensed technologies such as LAA.

    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 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.

    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.
