This message is sent on the EC-PACCH by the network to the mobile station to indicate the status of the received RLC data blocks. This message may also include a fixed uplink allocation for the mobile station to (re)transmit not yet acknowledged/transmitted RLC Data blocks. This message may also update the timing advance and power control parameters.
If the EGPRS Channel Coding Command parameter is not included in the message, the mobile station shall continue to use the previous EGPRS Modulation and Coding Scheme.
Message type: EC PACKET UPLINK ACK/NACK
Direction: network to mobile station
Classification: non-distribution message

EC Ack/Nack Description IE |
EC Primary Ack/Nack Description IE |
UL_COVERAGE_CLASS (2 bit field) bit 2 1 0 0 UL Coverage Class = CC1 0 1 UL Coverage Class = CC2 1 0 UL Coverage Class = CC3 1 1 UL Coverage Class = CC4 In case the UL Coverage Class is changed to CC1, the assignment is limited to 1 timeslot. The UL_COVERAGE_CLASS field shall be set according to the following table in case UL_COVERAGE_CLASS_EXT = 1: bit 2 1 0 0 UL Coverage Class = CC5 0 1 reserved 1 0 reserved 1 1 reserved |
STARTING_UL_TIMESLOT (3 bit field) bit 3 2 1 0 0 0 Timeslot 0 is the lowest assigned uplink timeslot 0 0 1 Timeslot 1 is the lowest assigned uplink timeslot 0 1 0 Timeslot 2 is the lowest assigned uplink timeslot 0 1 1 Timeslot 3 is the lowest assigned uplink timeslot A mobile station assigned CC2, CC3 or CC4 is always assigned 4 consecutive timeslots if the field EC_Reduced_PDCH_Allocation is set to 0 in the EC SYSTEM INFORMATION TYPE 2 message (see 44.018 sub-clause 9.1.43q). Therefore only timeslot 0, 1, 2, 3 or 4 may be indicated as the lowest assigned uplink timeslot when the assignment is for CC2, CC3, CC4, or CC5 in the uplink. If the field EC_Reduced_PDCH_Allocation is set to 1 a mobile station assigned CC2, CC3, CC4, or CC5 on the uplink is always assigned the use of 2 consecutive timeslots and therefore only timeslot 0, 1, 2, 3, 4, 5 or 6 shall be indicated as the lowest assigned uplink timeslot. |
DL_COVERAGE_CLASS (2 bit field) bit 2 1 0 0 DL Coverage Class = CC1 0 1 DL Coverage Class = CC2 1 0 DL Coverage Class = CC3 1 1 DL Coverage Class = CC4 |
STARTING_DL_TIMESLOT_OFFSET (2 bit field) If both UL_COVERAGE_CLASS and DL_COVERAGE_CLASS > CC1, the same timeslots are assigned in both the uplink and the downlink directions. The STARTING_DL_TIMESLOT_OFFSET field can then be considered as not valid by the mobile station. If UL_COVERAGE_CLASS = CC1 and DL_COVERAGE_CLASS > CC1, the STARTING_DL_TIMESLOT_OFFSET field is encoded according to the following code points if the field EC_Reduced_PDCH_Allocation is set to 0 in the EC SYSTEM INFORMATION TYPE 2 message (see 44.018 sub-clause 9.1.43q). If the field EC_Reduced_PDCH_Allocation is set to 1 only the first two code points of the following shall be used: bit 2 1 0 0 same timeslot as indicated by STARTING_UL_TIMESLOT 0 1 STARTING_UL_TIMESLOT – 1 1 0 STARTING_UL_TIMESLOT – 2 1 1 STARTING_UL_TIMESLOT – 3 If UL_COVERAGE_CLASS > CC1 and DL_COVERAGE_CLASS = CC1, the STARTING_DL_TIMESLOT_OFFSET field is encoded according to the following code points if the field EC_Reduced_PDCH_Allocation is set to 0 in the EC SYSTEM INFORMATION TYPE 2 message (see 44.018 sub-clause 9.1.43q). If the field EC_Reduced_PDCH_Allocation is set to 1 only the first two code points of the following shall be used: bit 2 1 0 0 same timeslot as indicated by STARTING_UL_TIMESLOT 0 1 STARTING_UL_TIMESLOT + 1 1 0 STARTING_UL_TIMESLOT + 2 1 1 STARTING_UL_TIMESLOT + 3 If both UL_COVERAGE_CLASS and DL_COVERAGE_CLASS = CC1, the downlink is assigned to the timeslot indicated by the STARTING_UL_TIMESLOT field. If timer T3248 (sent in EC SI) is used, the STARTING_DL_TIMESLOT_OFFSET field defines the lowest assigned timeslot for EC-PACCH transfers using CC2 while the timer is running. The STARTING_DL_TIMESLOT_OFFSET field is then encoded according to the following table: bit 2 1 0 0 same timeslot as indicated by STARTING_UL_TIMESLOT 0 1 STARTING_UL_TIMESLOT – 1 1 0 STARTING_UL_TIMESLOT – 2 1 1 no valid CC2 mapping applies while T3248 is running, CC1 to be used |

If the assigned uplink Coverage Class > CC1 (according to the UL_COVERAGE_CLASS field), the mobile station shall consider the TIMESLOT_MULTIPLICATOR field as not valid |

GAMMA (5 bit field) bit ALPHA Enable (1 bit field) 0 The mobile station shall not use the ALPHA parameter UL_COVERAGE_CLASS_EXT (1 bit field) bit 0 UL_COVERAGE_CLASS field indicates one of UL Coverage Class CC1, CC2, CC3 or CC4 are assigned for uplink 1 UL_COVERAGE_CLASS field indicates UL Coverage Class CC5 is assigned for uplink BSN_OFFSET (2 bit field) bit 2 1 0 0 Start with the 2^{nd} oldest RLC Data, to be transmitted, in the first resource within the fixed uplink allocation 0 1 Start with the 3^{rd} oldest RLC Data, to be transmitted, in the first resource within the fixed uplink allocation 1 0 Start with the 4^{th} oldest RLC Data, to be transmitted, in the first resource within the fixed uplink allocation 1 1 Start with the 5^{th} oldest RLC Data, to be transmitted, in the first resource within the fixed uplink allocation |
START_FIRST_UL_RLC_DATA_BLOCK (4 bit field) If uplink Coverage Class = CC1 and TIMESLOT_MULTIPLICATOR = 0 or if uplink Coverage Class = CC2, the START_FN_FIRST_UL_RLC_DATA_BLOCK field is encoded according to the following table: bit 4 3 2 1 0 0 0 0 In the TDMA frame (N+13) mod 2715648 0 0 0 1 In the TDMA frame (N+17 or N+18) mod 2715648 0 0 1 0 In the TDMA frame (N+21 or N+22) mod 2715648 0 0 1 1 In the TDMA frame (N+26) mod 2715648 0 1 0 0 In the TDMA frame (N+30 or N+31) mod 2715648 …. 1 1 1 0 In the TDMA frame (N+73 or N+74) mod 2715648 1 1 1 1 In the TDMA frame (N+78) mod 2715648 If uplink Coverage Class = CC1 and TIMESLOT_MULTIPLICATOR = 1, the START_FN_FIRST_UL_RLC_DATA_BLOCK field is encoded according to the following table: bit 4 3 2 1 0 0 0 0 In the timeslot with the lowest TN in TDMA frame (N+13) mod 2715648 0 0 0 1 In the timeslot with the highest TN in TDMA frame (N+13) mod 2715648 0 0 1 0 In the timeslot with the lowest TN in TDMA frame (N+17 or N+18) mod 2715648 0 0 1 1 In the timeslot with the highest TN in TDMA frame (N+17 or N+18) mod 2715648 …. 1 1 1 0 In the timeslot with the lowest TN in TDMA frame (N+43 or N+44) mod 2715648 1 1 1 1 In the timeslot with the highest TN in TDMA frame (N+43 or N+44) mod 2715648 If uplink Coverage Class = CC1 and TIMESLOT_MULTIPLICATOR = 2, the START_FN_FIRST_UL_RLC_DATA_BLOCK field is encoded according to the following table: bit 4 3 2 1 0 0 0 0 In the timeslot with the lowest TN in TDMA frame (N+13) mod 2715648 0 0 0 1 In the timeslot with the 2^{nd} lowest TN in TDMA frame (N+13) mod 2715648 0 0 1 0 In the timeslot with the highest TN in TDMA frame (N+13) mod 2715648 0 0 1 1 In the timeslot with the lowest TN in TDMA frame (N+17 or N+18) mod 2715648 0 1 0 0 In the timeslot with the 2^{nd} lowest TN in TDMA frame (N+17 or N+18) mod 2715648 0 1 0 1 In the timeslot with the highest TN in TDMA frame (N+17 or N+18) mod 2715648 …. 1 1 1 0 In the timeslot with the highest TN in TDMA frame (N+30 or N+31) mod 2715648 1 1 1 1 In the timeslot with the lowest TN in TDMA frame (N+34 or N+35) mod 2715648 If uplink Coverage Class = CC1 and TIMESLOT_MULTIPLICATOR = 3, the START_FN_FIRST_UL_RLC_DATA_BLOCK field is encoded according to the following table: bit 4 3 2 1 0 0 0 0 In the timeslot with the lowest TN in TDMA frame (N+13) mod 2715648 0 0 0 1 In the timeslot with the 2^{nd} lowest TN in TDMA frame (N+13) mod 2715648 0 0 1 0 In the timeslot with the 3^{rd} lowest TN in TDMA frame (N+13) mod 2715648 0 0 1 1 In the timeslot with the highest TN in TDMA frame (N+13) mod 2715648 0 1 0 0 In the timeslot with the lowest TN in TDMA frame (N+17 or N+18) mod 2715648 0 1 0 1 In the timeslot with the 2^{nd} lowest TN in TDMA frame (N+17 or N+18) mod 2715648 …. 1 1 1 0 In the timeslot with the 3^{rd} lowest TN in TDMA frame (N+26) mod 2715648 1 1 1 1 In the timeslot with the highest TN in TDMA frame (N+26) mod 2715648 |

uplink Coverage Class = CC5, the START_FN_FIRST_UL_RLC_DATA_BLOCK field is encoded according to the following table: If uplink Coverage Class = CC5 and the field EC_Reduced_PDCH_Allocation is set to 0 in the EC SYSTEM INFORMATION TYPE 2 message, (see 3GPP TS 44.018), the START_FN_FIRST_UL_RLC_DATA_BLOCK field is encoded according to the following table: 0 0 0 0 The 1^{st} uplink 52-multiframe occurring after the downlink 52-multiframe used to send the last blind physical layer transmission of this EC PACKET UPLINK ACK/NACK message 0 0 0 1 The 2^{nd} uplink 52-multiframe occurring after the
