a) = 1 with frequency hopping.
= 0 without frequency hopping.
b) = 1 with frequency hopping or change from Rx to Tx.
= 0 without frequency hopping and no change from Rx to Tx.
c) = 1 with frequency hopping or change from Tx to Rx.
= 0 without frequency hopping and no change from Tx to Rx.
d) = 1 change from Tx to Rx, or, with frequency hopping and the MS is either assigned a downlink dual carrier or DLMC configuration, or, the MS does not support fast downlink frequency switching (see 3GPP TS 24.008).
= 0 no change from Tx to Rx and either without frequency hopping or the MS is not assigned a downlink dual carrier configuration and supports fast downlink frequency switching (see 3GPP TS 24.008).
to = 31 symbol periods (this can be provided by a TA offset, i.e. a minimum TA value).
Type 1 MS are not required to transmit and receive at the same time.
Type 2 MS are required to be able to transmit and receive at the same time.
For HSCSD, only multislot classes 1 – 18 are recognised. An MS with a higher multislot class number shall indicate a suitable multislot class less than 19 for HSCSD applications (see 3GPP TS 44.018).
EC operation is only defined for Type 1 MS and hence only the multislot classes for Type 1 MS apply in Table B.1. Furthermore:
– ‘Sum’ does not apply since the MS is restricted to either transmit or receive during a TDMA frame.
– ‘Rx’ and ‘Tx’ only apply when blind physical layer transmissions are not used, i.e. when the MS is in CC1 on downlink and/or uplink respectively. When blind physical layer transmissions are used, the MS shall support four consecutive timeslots for transmission or reception, i.e. ‘Tx=4’ and ‘Rx=4’, irrespective of the declared multislot class.
– ‘Tra’ and ‘Tta’ do not apply since there is no requirement on downlink monitoring during an ongoing TBF.
– ‘Ttb’ does not apply since the time between reception of a Fixed Uplink Assignment and the corresponding Uplink allocation exceeds multiple TDMA frames.
– ‘Trb’ does not apply when assigning resource to an EC-GSM-IoT capable MS. The switching time can however apply for example after the MS has transmitted an EC-PACCH block on the uplink, before it can start monitoring the downlink, in which case the MS need not monitor downlink blocks where the ‘Trb’ is not fulfilled, see 3GPP TS 44.060.
Rx:
Rx describes the maximum number of receive timeslots that the MS can use 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). The receive TS need not be contiguous. For type 1 MS, the receive TS shall be assigned within 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 assigned within window of size Tx, and no receive TS shall occur between transmit TS within a TDMA frame.
Sum:
Sum is the total number of uplink (u) and downlink (d) TS that can actually be used by the MS per TDMA frame. The MS must be able to support all combinations of integer values of d <= Rx and u <= Tx TS where 1 <= d + u <= Sum (depending on the services supported by the MS). Sum is not applicable to all classes.
Sum is not applicable in EC operation.
Tta:
Tta relates to the time needed for the MS to perform adjacent cell signal level measurement and get ready to transmit.
For type 1 MS it is the minimum number of timeslots that will be allowed between the end of the previous transmit or receive TS and the next transmit TS when measurement is to be performed between. It should be noted that, in practice, the minimum time allowed may be reduced by amount of timing advance.
For type 1 MS that supports extended TA, the parameter Tta is increased by 1 if TA > 63 and there is a change from RX to TX.
For type 2 MS it is not applicable.
For circuit switched multislot configurations as defined in subclause 6.4.2.1, Tta is not applicable.
Tta is not applicable in EC operation.
Ttb:
Ttb relates to the time needed for the MS to get ready to transmit. This minimum requirement will only be used when adjacent cell power measurements are not required by the service selected.
For type 1 MS it is the minimum number of timeslots that will be allowed between the end of the last previous receive TS and the first next transmit TS or between the previous transmit TS and the next transmit TS when the frequency is changed in between. It should be noted that, in practice, the minimum time allowed may be reduced by the amount of the timing advance.
For type 1 MS that supports extended TA, the parameter Ttb = 2 if TA > 63 and there is a change from RX to TX.
For type 2 MS it is the minimum number of timeslots that will be allowed between the end of the last transmit burst in a TDMA frame and the first transmit burst in the next TDMA frame.
Ttb is not applicable in EC operation.
Tra:
Tra relates to the time needed for the MS to perform adjacent cell signal level measurement and get ready to receive.
For type 1 MS it is the minimum number of timeslots that will be allowed between the previous transmit or receive TS and the next receive TS when measurement is to be performed between.
For type 2 MS it is the minimum number of timeslots that will be allowed between the end of the last receive burst in a TDMA frame and the first receive burst in the next TDMA frame.
An MS, except for multislot class 30 – 45, shall be able to decode SCH from a neighbour cell, independent of its relative timing, using an idle frame in combination with Tra from the preceding frame.
Tra is not applicable in EC operation.
Trb:
Trb relates to the time needed for the MS to get ready to receive. This minimum requirement will only be used when adjacent cell power measurements are not required by the service selected.
For type 1 MS it is the minimum number of timeslots that will be allowed between the previous transmit TS and the next receive TS or between the previous receive TS and the next receive TS when the frequency is changed in between.
For type 2 MS it is the minimum number of timeslots that will be allowed between the end of the last receive burst in a TDMA frame and the first receive burst in the next TDMA frame.
