Patent ID: 7447504

Claim:
A method for performing a data allocation process for scheduled data, non-scheduled user data and non-scheduled control data obeying restrictions on the resource utilization defined by a non-scheduled grant, wherein a non-scheduled grant indicates the maximum amount of resources a mobile terminal is allowed to utilize for transmitting non-scheduled data on the uplink channel within a transmission time interval, the method comprising: restricting a non-scheduled grant to a subset of a plurality of HARQ processes thereby activating the HARQ processes of said subset for transmitting non-scheduled user data, whereby the restriction deactivates the remaining HARQ processes of the plurality of HARQ process for transmitting non-scheduled user data and does not deactivate said remaining HARQ processes for transmitting non-scheduled control data, multiplexing non-scheduled user data and non-scheduled control data to a packet data unit of a transport channel for transmission on the uplink channel using one of the plurality of HARQ processes according to the non-scheduled grant thereby taking into account whether the HARQ process is active for the transmission of non-scheduled user data, and providing the packet data unit for transmission on the uplink channel in the next transmission time interval to the HARQ process.
