Sylvain Munaut 246tnt at gmail.comHi, > I have Tx disabled anyway, but it didn't hit me until you said it out loud. > Dedicated-mode SDCCH also has uplink slots, doesn't it? Yes. And it also has SACCH slots that the CBCH doesn't have. > To make this work I guess we need to implement some separate CBCH mode in > L1. Yup. It seems that CBCH never have subslots ? (Looking at GSM 05.02 Clause 7 Table 3 of 9). If it says SDCCH4 it's always B32..B35 (like a SDCCH4 subslot 2) If it says SDCCH8 it's always B8..B11 (like a SDCCH8 subslot 2) I'll look into adding a command to support going to that channel along with the appropriate scheduling. > In which case, I suppose it should be possible to continue receiving CCCH > at the same time? No, we can only get data from 1 timeslot in each frame, so if it's in a SDCCH8 there can be conflicts. (If it's in SDCCH/4 then that should be OK) We'll probably be able to do that only when we get to DRX (where we only listen to specific slots). Cheers, Sylvain
