B.4 Multislot capabilities for dual carrier mobile stations
3GPP45.002GSM/EDGE Multiplexing and multiple access on the radio pathRelease 17TS
For mobile stations supporting downlink dual carrier, the multislot capability applicable to dual carrier operation is dependent on the (DTM) EGPRS (high) multislot class (see subclause B.1), on the Multislot Capability Reduction for Downlink Dual Carrier field (see 3GPP TS 24.008) and, if provided, on the Alternative EFTA multislot class field (see subclause B.5) and on the EFTA Multislot Capability Reduction for Downlink Dual Carrier field (see 3GPP TS 24.008) as signalled by the mobile station as defined in Table B.2. Only mobile stations of multislot classes listed in Table B.2 can support downlink dual carrier.

NOTE 0: These configurations can only be used for assignment to an MS supporting Enhanced Flexible Timeslot Assignment (see 3GPP TS 24.008).
The values of Rx’, Tx’ and Sum’ and Rx_Sum apply for downlink dual carrier configurations.
If the MS has not indicated support for Enhanced Flexible Timeslot Assignment (see 3GPP TS 24.008), then Rx’, Tx’ and Sum’ correspond to Rx, Tx and Sum for the Equivalent multislot class (see Table B.2) and the values of Tta, Ttb, Tra and Trb of the equivalent multislot class shall then apply as indicated by Table B.2; if no equivalent multislot class is specified then Rx’, Tx’ and Sum’ correspond to Rx, Tx and Sum respectively for the signalled multislot class and the switching times Tta, Ttb, Tra and Trb of the signalled multislot class shall apply.
If the MS has indicated support for Enhanced Flexible Timeslot Assignment (see 3GPP TS 24.008), then Rx’, Tx’ and Sum’, Tta, Ttb, Tra and Trb all correspond to Rx, Tx, Sum, Tta, Ttb, Tra and Trb respectively as defined in subclause B.5.
Possible switching and measurement timings for downlink dual carrier MSs that have a higher equivalent multislot class compared to the signalled multislot class are illustrated in Annex E.
Rx_Sum is given by the Maximum Number of downlink timeslots as specified in Table B.2 minus the number of timeslots indicated in the Multislot Capability Reduction for Downlink Dual Carrier field (see 3GPP TS 24.008).If the resultant Rx_Sum is lower than the value given by the field Sum in Table B.1 for the signalled multislot class (or the equivalent multislot class if different from signalled multislot class) (see Table B.2), then Rx_Sum shall be assumed to be equal to Sum from Table B.1 for that multislot class.
If the MS has indicated support for Enhanced Flexible Timeslot Assignment (see 3GPP TS 24.008), then Rx_Sum_EFTA is given by the Maximum Number of downlink timeslots as specified in Table B.2 minus the number of timeslots indicated in the EFTA Multislot Capability Reduction for Downlink Dual Carrier field (see 3GPP TS 24.008). If the resultant Rx_Sum_EFTA is lower than or equal to the value given by the field Rx in Table B.1 either for the indicated alternative EFTA multislot class, or for the signalled (DTM) EGPRS (high) multislot class if no alternative EFTA multislot class is indicated, then Rx_Sum_EFTA shall be assumed to be equal to Rx + 1 from Table B.1 for that multislot class.
NOTE: The Equivalent multislot class and corresponding switching times (where different from the signalled multislot class) apply only for dual carrier assignments. For assignments which use only one carrier, the signalled multislot class (and corresponding switching times as specified in Table B.1) apply.
Rx’:
Rx’ describes the maximum number of receive timeslots that the MS can use per radio frequency channel per TDMA frame. The MS must be able to support all integer values of receive TS from 0 to Rx’ (depending on the services supported by the MS) on each radio frequency channel. The receive TS need not be contiguous. For type 1 MS, all the receive TS (on both radio frequency channels) shall be allocated within a window of size Rx’, and no transmit TS shall occur between receive TS within a TDMA frame.
Tx’:
Tx’ describes the maximum number of transmit timeslots that the MS can use per TDMA frame.The MS must be able to support all integer values of transmit TS from 0 to Tx’ (depending on the services supported by the MS). The transmit TS need not be contiguous. For type 1 MS, the transmit TS shall be allocated within window of size Tx’, and no receive TS shall occur between transmit TS within a TDMA frame.
NOTE: All transmit timeslots are allocated on the same uplink radio frequency channel within a radio block period.
Sum’:
Sum’ is the total number of uplink TS and downlink TS (on either radio frequency channel) that can be used by the MS per TDMA frame. The MS must be able to support all combinations of integer values of 1 <= d1 <= Rx’, 1 <= d2 <= Rx’ and u <= Tx’ TS where 1 <= d1 + u <= Sum’ and 1 <= d2 + u <= Sum’ (depending on the services supported by the MS).
Rx_Sum:
Rx_Sum is the total number of downlink TS (on both radio frequency channels) that can be received by the MS per TDMA frame when not using Enhanced Flexible Timeslot Assignment, EFTA. The MS must be able to support all combinations of integer values of d1 and d2 where 1 <= d1 +d2 <= Rx_Sum (depending on the services supported by the MS).
Rx_Sum_EFTA:
Rx_Sum_EFTA is the total number of downlink TS (on both radio frequency channels) that can be received by the MS per TDMA frame when using Enhanced Flexible Timeslot Assignment, EFTA. The MS must be able to support all combinations of integer values of d1 and d2 where 1 <= d1 +d2 <= Rx_Sum_EFTA (depending on the services supported by the MS).
NOTE: Both d1 and d2 need to be different from 0 in order for Sum’, Rx_Sum and Rx_Sum_EFTA to apply.
