58b.2.5 Concurrent Downlink Dual Carrier TBF / Downlink Dual Carrier Configuration in Dual Transfer Mode

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

58b.2.5.1 Conformance requirement

A mobile station in dual transfer mode in a Downlink Dual Carrier configuration shall respond in the

uplink radio block on the timeslot or on the PDCH pair indicated by the RRBP field or by the CES/P field, on the uplink

radio frequency channel where the dedicated resource is assigned regardless of which downlink radio frequency channel

the poll was received on. The network shall not poll the mobile station in a manner which would require the mobile

station to respond on the same timeslot as that on which the dedicated resource is assigned.

A mobile station in dual transfer mode in a Downlink Dual Carrier configuration shall respond in the uplink radio block on the timeslot or the PDCH pair indicated by the RRBP field (see sub-clause 10.4.5) on the uplink radio frequency channel where the dedicated resource is assigned regardless of which downlink radio frequency channel the poll was received on, unless this would prevent the transmission or reception of a TCH radio block on a dedicated resource.

58b.2.5.2 Test purpose

To verify that:

The MS receives downlink data blocks on the time slots assigned on the two carriers in the DLDC configuration.

58b.2.5.3 Method of test

Initial Conditions

System Simulator:

1 cell, EGPRS supported, Downlink Dual Carrier supported and DTM supported.

Mobile Station:

Support for Downlink Dual Carrier indicated in MS Radio Access Capabilities IE.

Support for Downlink Dual carrier for DTM capability in MS Radio Access Capabilities IE.

Support of DTM is indicated in SI6 in dedicated mode and in SI13 in idle mode.

The MS is in the state "idle, GMM-registered" with a P-TMSI allocated, SPLIT PG CYCLE negotiated, and PDP context 2 activated.

Test Procedure

Once the MS is in DTM, the SS assigns uplink resources in the Packet Uplink assignment IE and downlink resources in the Packet downlink Assignment IE of the DTM Assignment Command message. SS assigns time slots on two carriers C1 and C2 and brings MS in DLDC configuration. The SS sends RLC data blocks on Carrier 1 and Carrier 2 simultaneously. MS when polled acknowledges all data blocks send by SS. SS makes sure that MS sends all the data blocks on the assigned timeslot.

Maximum Duration of Test

5 minutes.

MS in state U10, on Timeslot N (chosen arbitrarily),

utilising either:

k=1, Channel Type = TCH/F; or

k=2, Channel Type = TCH/H.

Trigger the MS to initiate an uplink packet transfer

Containing 2kB of data.

DTM ASSIGNMENT COMMAND

NW sets Packet Downlink Assignment Type to 2 and Allocates 2 carriers with TIMESLOT_ALLOCATION_C1 and TIMESLOT_ALLOCATION_C2 arbitrarily chosen (default timeslot 4).

Packet Uplink Assignment IE set to

EGPRS_MCS_MODE : MCS -9

EGPRS Window Size : 192

TIMESLOT_ALLOCATION : 5

ASSIGNMENT COMPLETE

6

SS -> MS

RLC DATA BLOCK

On carrier 1 with next in sequence BSN (Start with BSN 0). USF Assigned

7

SS -> MS

RLC DATA BLOCK

On carrier 2 with next in sequence BSN

Sent on same Radio Block as Data Block send on Carrier 1. Valid RRBP field

8

MS -> SS

EGPRS UPLINK RLC DATA BLOCK

Received on the assigned PDTCH on carrier1

SS verifies that the correct BSN is received and the correct MCS is used.

9

SS -> MS

EGPRS PACKET DOWNLINK ACK/NACK

Received on carrier 2 in the allocated uplink block.

10

Repeat Steps 6 to 9 to verify that both uplink and downlink data transmission is functioning correctly.
