E-AGCH - DCH Absolute Grant Channel

The E-DCH Absolute Grant Channel is a downlink physical channel carrying the uplink E-DCH absolute grant information. Key parameters include: Absolute Grant Value and Absolute Grant Scope, as well as individual or group RNTI (Radio Network Temporary Identifier) values which are coded using an identity specific CRC value. 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.
