E-RGCH - DCH Relative Grant Channel

The E-DCH Relative Grant Channel is very similar to the E-HICH. It is a downlink channel used for carrying the uplink E-DCH relative grants. There are two types of grants: – Absolute Grants – these provide an absolute limitation of the maximum amount of UL (Uplink) resources the UE may use. These are sent on an E-AGCH. – Relative Grants – these increase or decrease the resource limitation compared to the previously used value. These are sent on an E-RGCH.
