A.2 Blind transport format detection using pseudo-flexible positions

25.2123GPPMultiplexing and channel coding (FDD)Release 17TS

The blind detection procedure for each TTI begins by assuming a hypothesis for all values of RM_i of Equation (1) of subclause 4.2.7, based on a corresponding hypothesis regarding whether certain TrCHs are delivering a transport block during that TTI. Based on this hypothesis, the blind detection then proceeds similar to blind transport format detection with fixed positions. If this hypothesis results in a successful detection of at least one transport format based on a passing CRC, the assumed hypothesis is considered to be validated to be correct. If there is no passing CRC, this process is repeated with another hypothesis, until all hypotheses are exhausted.

Annex B (informative):
Compressed mode idle lengths

The tables B.1-B.3 show the resulting idle lengths for different transmission gap lengths, UL/DL modes and DL frame types when DPCCH/DPDCH are used in the uplink and DPCH in the downlink. The idle lengths given are calculated purely from the slot and frame structures and the UL/DL offset. They do not contain margins for e.g. synthesizer switching.
