Dual carrier modulation with single carrier reception

Abstract

A method of a wireless terminal configured to operate in a wireless network using at least one wideband channel is disclosed. The wireless terminal is configured to operate in a narrowband within the wideband channel. The network comprises at least one other wireless terminal configured to operate in the entire wideband channel, and at least one access point (AP). The AP is configured to support transmission and reception over the entire wideband channel, wherein the wideband channel is dividable into a plurality of resource units. The method comprises receiving a trigger from the AP, wherein the trigger comprises an indication of a first resource unit and a second resource unit of the plurality of resource units on which the AP will transmit data intended to the wireless terminal using a dual carrier modulation (DCM) transmission and measuring a signal quality of the first and second resource units by measuring, in a frequency of the wideband channel which corresponds to the first and second resource unit, a reception quality of data transmitted from the AP to the at least one other wireless terminal. The method also comprises determining which of the first and second resource units has a highest signal quality based on the measured signal quality and receiving the DCM-transmission on the resource unit determined to have the highest signal quality. Also disclosed is an arrangement of a wireless terminal and an access point, a method of an access point, an access point, a wireless terminal and a computer program product.
