IPC: H04W52/34
Filed: 2010-06-30
Abstract: A method of optimizing downlink for communications between a base station and mobile stations in a wireless communication system involves acquiring user identifiers and geometry values for mobile stations that are associated with registered users of the system, associating modulation control scheme (MCS) power values with respective users in response to respective geometry values, initializing a power pool, identifying users that have an MCS power value greater than a reference MCS power value as high power users and calculating a power difference for each of the high power users. The power difference is a difference between the geometry value associated with each of the high power users and a reference geometry value associated with the reference MCS power value respectively. The power differences associated with respective high power users are accumulated in the power pool, by summing the power differences. Users that have an MCS power value below the reference MCS power value are identified as low power users and increased geometry values are associated with at least some of the low power users while the power pool is reduced by corresponding amounts until the power pool is depleted. New MCSs are then determined for at least some of the low power users based on the increased geometry values and control information is transmitted to the low power users using modulation and control schemes identified by the corresponding new MCSs at power levels associated with the new MCSs.

Filed: 2010-09-29
Abstract: Because of the formation of disulfide bridges with mucus glycoproteins, the mucoadhesive properties of polymeric compounds can. be significantly improved by the covalent attachment of thiol substructures to them. By the transformation of free thiol groups on such polymers in disulfides with mercaptonicotinamides or mercaptopyridoxins these thiol groups become comparatively more reactive resulting in significantly improved mucoadhesive properties.  Furthermore, polymers exhibiting disulfide partialstructures with mercaptonicotinamides or mercaptopyridoxins do not need to be protected against oxidation. In addition, they show comparatively higher permeation enhancing properties.
