Apparatus and method for communicating signaling information

摘要

A User Equipment, UE, of a cellular communication system transmits scheduling assistance data to a base station comprising a base station scheduler which schedules packet data. The scheduling assistance data relates to packet data communication of the UE. The scheduling assistance data is generated by a scheduling assistance data generator coupled to a packet data transmit buffer associated with the packet data transmission. A first transport channel controller allocates other data to a first transport channel and a retransmission controller operates a retransmission scheme for this transport channel. A second transport channel controller allocates the scheduling assistance data to a signaling transport channel and a transport channel multiplexer combines the two transport channels as multiplexed channels on a single physical resource. The transmission reliabilities for the retransmission and non-retransmission transport channels may be individually optimized.
