  • Patch Set #1, Line 486: * way we help BTS energy saving (on TRX!=C0) by sending nothing

    IIRC osmo-bts-trx does something slightly different if it detects no block is to be sent because no […]

    That makes more sense now, so when we can safely assume that nobody is listening, then we skip the idle blocks. The TRX then sends idle blocks for us which are reduced in power so that energy is saved. (Why not turning off the TRX completely? Nobody is listening anyway? Or is this forbidden by the spec?)

    When I get this right the skipping of idle blocks only refers to the periods where no TBF is allocated. When there is a TBF we still send dummy blocks from the PCU.
