摘要： The present invention provides a composition for forming a liquid crystal alignment film, which comprises a photoreactive polymer including a multicyclic compound having a photoreactive group on a main chain thereof. The present invention also provides a liquid crystal alignment film produced using the composition, and a liquid crystal display including the liquid crystal alignment film. The photoreactive polymer including the multicyclic compound on the main chain thereof has a high glass transition temperature, thus thermal stability is excellent. Since lattice vacancy is relatively large, the photoreactive group is capable of moving relatively freely in the main chain of the polymer, thus it is possible to improve a slow photoreaction rate, which is considered a disadvantage of a conventional polymer material.

摘要： The present invention relates to transmitting data units of a radio protocol layer, wherein one logical channel identifier is added to one or more data units belonging to one logical channel. Because only one logical channel identifier is added to the data units belonging to one logical channel in constructing a MAC-e PDU, overheads of the MAC-e PDU are reduced. Such reduction of the PDU overheads increases data throughput, which is advantageous for a high-speed data communication system, such as the HSUPA.
