Hi All,
We have noticed that the PCU sends invalid block number to L1 in DSP leading to
unexpected message warning in DSP “GsmL1_PhDataReq(1) : Unexpected burst (Invalid
blockNumber) [2!=1, SAPI 21-21]]”.
After an investigation, we observe that the ‘pcu_rx_rts_req’ function in pcu_l1_if.cpp
receives invalid block number from BTS.
Looking at the BTS side, the calculation of L1SAP_FN2PTCCHBLOCK defined as ‘#define
L1SAP_FN2PTCCHBLOCK(fn) ((fn / 52) & 7)’ does not seem to be valid for expected PTCCH
block numbers B0, B1,B2,B3 defined in Table 6 in TS 05.02 version 8.11.0.
How do you execute the PCU? By opening the PDCH queue directly or by getting all
information from the BTS?
