Access Point, Station, Methods and Computer Programs

Abstract:

An access point is arranged for serving both wideband wireless stations and narrowband wireless stations where the narrowband wireless stations operate on a subset of the bandwidth on which the wideband wireless stations operate. The access point comprises a transceiver and a controller. The controller is arranged to schedule simultaneous usage of a first set of subcarriers for a wideband station and a first narrowband wireless station by causing the transceiver to transmit a first subcarrier suggestion, about the first set of subcarriers to be used, to the first narrowband wireless station and to transmit a modulation and coding scheme, MCS suggestion, about subcarriers including the first set of subcarriers to be used, to the wideband station. The suggested MCS is adapted to have increased robustness in view of any interference on a transmission from the wideband wireless station caused by a transmission from the first narrowband wireless station in the first set of subcarriers. A station arranged to communicate with the access point, and methods and computer programs are also disclosed.
