Resource allocation in a wireless network

Abstract

A wireless communication system and method employing channel transport format allocation in a shared uplink channel between a UE and a Node B, and wherein the UE can determine a transport format combination which it can support, by: detecting in the UE a change in transport format combination that the UE can support; and sending to the Node B an indication of transport format combination that the UE can support, whereby efficiency of channel transport format allocation in the system may be improved. A conditional delay mechanism may be employed to reduce signalling overhead. This allows uplink shared channels to be efficiently used by providing a means by which UTRAN (UMTS terrestrial radio access network) is informed of the TFCs within the TFCS which can be used in the uplink by the UE.A wireless network for configuring transport format combinations (TFCs) is disclosed. The wireless network may send to a user equipment (UE) information with an indication of a plurality of TFCs that can be used for uplink transmission The UE may select a TFC and determine if another TFC is supported by a comparison of a transmission power to a maximum UE transmit power. The UE may send an indication that a higher data rate TFC is supported. The UE may then receive, in relation to the indication, an allocation of uplink resources.
