<p><P>PROBLEM TO BE SOLVED: To provide a method for improving interaction between a scheduling request (SR) procedure and a random access (RA) procedure in a user equipment (UE), in order to prevent uplink transmission error or RA procedure failure that may occur when performing the RA procedure corresponding to the SR procedure and to provide a communication apparatus. <P>SOLUTION: The method includes steps of: triggering a SR procedure (S402); repeatedly sending a dedicated scheduling request (D-SR) message on a physical uplink control channel (PUCCH) until an uplink transmission resource assigned for a new transmission is received or the number of D-SR transmissions reaches to a specific value when the PUCCH is configured for the UE (S404); and deactivating all pre-configured transmission resources assigned to the UE before performing an RA procedure corresponding to the SR procedure when the number of D-SR transmissions reaches to the specific value (S406). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
