{Uplink dynamic allocation two phase access}

Macro parameters:

N: the number of data octets to be transferred,

USF_GRANULARITY: 1 or 4 blocks,

RLC_DATA_BLOCKS_GRANTED: 9-261 (close-end) or absent (open-end),

EGPRS Channel Coding Command: MCS-1, -2, -3, -4, -5, -6, -6, -7, -8, -9 or MCS-5-7, MCS6-9,

Resegment IE: incremental redundancy on/off in uplink direction,

EGPRS Window Size: according to number of allocated timeslots,

TLLI_BLOCK_CHANNEL_CODING: MCS-1 or as data block,

TBF Starting Time:

0

MS

Trigger the MS to initiate uplink transfer of N octets of data according to the activated test PDP context.

1

MS -> SS

EGPRS PACKET CHANNEL REQUEST

Received on RACH.

2

SS -> MS

IMMEDIATE ASSIGNMENT

Multi block assignment allocating two blocks using Multiblock Allocation Struct, to order the MS to follow the two-phase access procedure. Sent on AGCH.

3

MS -> SS

PACKET RESOURCE REQUEST

Two phase access procedure. Received on the multi block assigned in step 2. EGPRS capability indicated in the MS Radio Access Capability IE.

Check that the PEAK_THROUGHPUT, RADIO_PRIORITY and RLC_MODE are compliant with the PDP context used.

3a (conditional)

MS -> SS

ADDITIONAL MS RADIO ACCESS CAPABILITIES

If <ADDITIONAL MS RAC INFORMATION AVAILABLE> field in the received PACKET RESOURCE REQUEST message (step 3) indicates 1, then step 3a is performed.

3b (optional)

MS -> SS

uplink control block (e.g. PACKET MEASUREMENT REPORT, PACKET UPLINK DUMMY CONTROL BLOCK)

If <ADDITIONAL MS RAC INFORMATION AVAILABLE> field in the received PACKET RESOURCE REQUEST message (step 3) indicates 0, then step 3b is optionally performed.

4

SS -> MS

PACKET UPLINK ASSIGNMENT

Uplink dynamic allocation, no starting time (as default, otherwise use TBF Starting Time), sent on PACCH of the same PDCH assigned in step 2.

53.3.2.3 Macro for downlink TBF establishment using ACCESS TYPE = "signalling" (PBCCH not present)

The following table describes a signalling sequence performing a downlink TBF establishment procedure.

The macros in the test cases refer to the table below starting at the step required for the particular sequence.

These steps are only applicable to mobiles that support EGPRS Packet Channel Request with Establishment Cause ‘signalling’ on RACH in a cell supporting EGPRS Packet Channel Request.
