Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a resource allocation method for expansion uplink using a shared control channel.

SOLUTION: User equipment (UE) selects one signature from a set of signatures available for random access regarding expansion uplink generates an access preamble on the basis of the selected signature and sends the access preamble for random access while operating in an inactive state. The UE receives from a shared control channel a resource allocated for the UE. The UE determines an UE identifier (ID) allocated beforehand in association with the selected signature demasks a received symbol for the shared control channel on the basis of the UEID allocated beforehand decodes the demasked symbol to obtain a codeword and determines the allocated resource on the basis of the codeword. The UE transmits data to a node B using the allocated resource while maintaining the inactive state.
