Method of increasing the capacity of enhanced data channel on uplink in a wireless communications systems
First Claim
1. A method in a wireless communication system comprising the step of:
- if a predetermined condition of data being transmitted on a dedicated physical data channel is determined to be present, reducing the amount control information transmitted on a dedicated physical control channel that is associated with the dedicated physical data channel, which control information is used for decoding the data on the dedicated physical data channel.

Abstract
In a UMTS wireless communication system, when the packet size on the enhanced dedicated physical data channel (E-DPDCH) on the uplink from a UE to a NodeB reaches a converged default packet size, the corresponding dedicated physical control channel (E-DPCCH) is turned off. The NodeB uses the default packet size to decode the frame received on the E-DPDCH using each possible redundancy version. Alternatively, the E-DPCCH is turned off and a new transmission flag is transmitted by the UE only when a new frame is transmitted by the UE. NodeB then uses the presence or absence of that flag in conjunction with the absence of E-DPCCH to determine which redundancy version is to be assumed in decoding the frame received on E-DPDCH.
