A network is running baseband hopping (BCCH included) with SDCCH allocated on TCH. Consider two nearby cells: BCCH1=TCH2 and BSIC1=BSIC2. Problems with SDCCH timeouts are encountered and they go away when BSIC1 or BSIC2 is changed.
I don’t have explanation for this. BSIC is broadcast on BCCH and only co-BCCH/co-BSIC reuse should be relevant. Can anyone comment potential co-BCCH/TCH + co-BSIC reuse? Thank you in advance.
