6.4 Erroneous frame indication performance

3GPP45.005GSM/EDGE Radio transmission and receptionTS

a) On a speech TCH (TCH/FS, TCH/EFS, TCH/HS, TCH/AFS, TCH/AHS, TCH/WFS, O-TCH/AHS, O-TCH/WFS or O-TCH/WHS) or a SDCCH with a random RF input, of the frames believed to be FACCH, O-FACCH, SACCH, or SDCCH frames, the overall reception performance shall be such that no more than 0,002 % of the frames are assessed to be error free.

b) On a speech TCH (TCH/FS, TCH/EFS, TCH/HS, TCH/AFS, TCH/AHS, TCH/WFS, O-TCH/AHS, O-TCH/WFS or O-TCH/WHS) with a random RF input, the overall reception performance shall be such that, on average, less than one undetected bad speech frame (false bad frame indication BFI) shall be measured in one minute.

c) On a speech TCH (TCH/FS, TCH/EFS, TCH/HS, TCH/AFS, TCH/AHS, TCH/WFS, O-TCH/AHS, O-TCH/WFS or O-TCH/WHS), when DTX is activated with frequency hopping through C0 where bursts comprising SID frames, SACCH frames and Dummy bursts are received at a level 20 dB above the reference sensitivity level and with no transmission at the other bursts of the TCH, the overall reception performance shall be such that, on average less than one undetected bad speech frame (false bad frame indication BFI) shall be measured in one minute for MS. This performance shall also be met in networks with one of the configurations described in 3GPP TS 45.002 – annex A, excepted combinations #1 and #6 of table A.2.5.1 for which there is no performance requirement.

d) On a speech TCH (TCH/FS, TCH/EFS, TCH/HS, TCH/AFS, TCH/AHS, TCH/WFS, O-TCH/AHS, O-TCH/WFS or O-TCH/WHS), when DTX is activated with SID frames and SACCH frames received 20 dB above the reference sensitivity level and with no transmission at the other bursts of the TCH, the overall reception shall be such that, on average, less than one undetected bad speech frame (false bad frame indication BFI) shall be measured in one minute for BTS.

e) For a BTS on a RACH or PRACH with a random RF input, the overall reception performance shall be such that less than 0,02 % of frames are assessed to be error free.

f) For a BTS on a EC-RACH with a random RF input, the overall reception performance shall be such that less than 0,02 % of blocks are assessed to be error free. This requirement applies for 1TS EC-RACH and/or 2TS EC-RACH, depending on what is supported by the BTS.

g) For an MS assigned a USF on a PDCH with a random RF input or a valid PDCH signal with a random USF not equal to the assigned USF, the overall reception shall be such that the MS shall detect the assigned USF in less than 1% of the radio blocks for GMSK modulated signals, and 1 % for 8-PSK modulated signals, and 1 % for QPSK, 16-QAM and 32-QAM modulated signals. This requirement shall be met for all input levels up to –40 dBm for GMSK, QPSK, 8PSK, 16QAM and 32QAM modulated signal. In case of DLMC configuration the performance shall, at the multiple input signals arbitrarily distributed over the maximum supported DLMC carrier frequency spacing, be met for all input levels up to -40 dBm per carrier but with the total input power limited to -37 dBm, irrespective of the number of carriers.

h) The FER on an SACCH associated to an adaptive speech traffic channel (TCH/AFS, TCH/AHS, TCH/WFS, O-TCH/AHS, O-TCH/WFS or O-TCH/WHS) received at 3 dB below the reference co-channel interference level shall be less than 40% tested under TU 3 / TU 1.5 propagation conditions.

i) On a speech TCH (TCH/AFS, TCH/AHS, TCH/WFS, O-TCH/AHS, O-TCH/WFS or O-TCH/WHS), a RATSCCH message, respectively a RATSCCH marker, shall be detected if more than 72% of the bits of the RATSCCH identification field (defined in 3GPP TS 45.003) are matched by the corresponding gross bits of the received frame.
