  • Publication number: 20050118959
    Abstract: The invention discloses a mobile-unit-assisted modulation scheme management, in which a mobile unit (100) performs signal quality measurements on a communications link (410), over which data modulated with a first modulation scheme is communicated. The mobile unit (100) determines a first link quality measure for this first modulation. Furthermore, the mobile unit (100) estimates second quality measure(s) for currently non-employed modulation scheme(s) based on this first quality measure. Selection information is then generated based on this first quality measure and the second quality estimate(s). This quality measure estimation is performed based on the capabilities and the particular modulation scheme versions of the mobile unit (100).

  • Publication number: 20050064890
    Abstract: The invention involves selection of modulation scheme for a mobile unit (100) having access to a link quality enhancing algorithm (130) operable only on data modulated using a subset of the available modulation schemes. The mobile unit (100) performs signal quality measurements on a communications link (410), over which data modulated with a first modulation scheme is communicated. A link quality measure is then determined for this first modulation. A quality enhancement due to operation of the algorithm (130) is also determined. This quality measure and the quality enhancement are used for generating decision information, which is reported to the network (200). There the information is used for estimating link quality measure(s) of currently non-employed modulation(s) for the mobile unit (100). The selection of a modulation scheme for the communications link is then performed based on the decision information and the estimated quality measure(s).
