6.4 Erroneous frame indication performance

05.053GPPRadio transmission and receptionTS

a) On a speech TCH (TCH/FS, TCH/EFS, TCH/HS, TCH/AFS or TCH/AHS) or a SDCCH with a random RF input, of the frames believed to be 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 or TCH/AHS) 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 or TCH/AHS), 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 05.02 – 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 or TCH/AHS), 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 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.

  1. For an MS allocated a USF on a PDCH with a random RF input or a valid PDCH signal with a random USF not equal to the allocated USF, the overall reception shall be such that the MS shall detect the allocated USF in less than 1% of the radio blocks, for GMSK modulated signals and 1 % for 8-PSK modulated signals. This requirement shall be met for all input levels up to –40 dBm for GMSK modulated signal, and up to -40 dBm for 8-PSK modulated signals.

h) The FER on an SACCH associated to an adaptive speech traffic channel (TCH/AFS or TCH/AHS) 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 or TCH/AHS), 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 05.03) are matched by the corresponding gross bits of the received frame.
