US 7551625 – Claim 16 3GPP Specifications

A method of scheduling an uplink packet 

transmission channel for user 

equipment (UE), the method 

comprising: 

receiving a scheduling assignment in an 

Enhanced Absolute Grant Channel (EAGCH),

3GPP TS 25.211 V6.7.0

5 Physical channels and physical signals

5.3 Downlink physical channels

5.3.3 Common downlink physical channels

5.3.3.14 E–DCH Absolute Grant Channel (E-AGCH)

The E-DCH Absolute Grant Channel (E-AGCH) is a fixed rate (30 kbps, SF=256) 

downlink physical channel carrying the uplink E-DCH absolute grant. Figure 

26C illustrates the frame and sub-frame structure of the E-AGCH.

An E-DCH absolute grant shall be transmitted over one E-AGCH sub-frame 

or one E-AGCH frame. The transmission over one E-AGCH sub-frame and 

over one E-AGCH frame shall be used for UEs for which E-DCH TTI is set to

respectively 2 ms and 10 ms.

9.1 General Principle

⁞

The Scheduling Grants have the following characteristics:

- Scheduling Grants are only to be used for the E-DCH TFC selection 

algorithm (i.e. they do not influence the TFC selection for the DCHs);

⁞

- Absolute Grants are sent by the Serving E-DCH cell:

- They are valid for one UE, for a group of UEs or for all UEs;

- The Absolute Grant contains:

- the identity (E-RNTI) of the UE (or group of UEs) for which the 

grant is intended (through an IDspecific CRC attachment);

⁞

- Up to two identities (E-RNTIs), one primary and one secondary, can be 

allocated to a UE at a time. In that case, both identities shall use the 

same E-AGCH channel. The allocation is done by the Node-B and sent 

by the SRNC in RRC.

The Serving Grant Update function provides the E-TFC selection function 

with the maximum E-DPDCH to DPCCH power ratio that the UE is allowed to 

allocate for the upcoming transmission for scheduled data (held in the 

Serving Grant state variable – see subclause 11.8.1.3).
