Hello dear experts,
Questions or Scheduling Request SR and uplink transmissions in general. I realize this is a MAC concept. The UE sends SR requesting uplink resources. Question what does SR look like at the PHY layer? I know it should be series of 0s and 1s at PHY layer but how is it different than say HARQ acks. When the gnb decodes information how does UE know this is SR versus this is ACK or PUSCH?
Thank you very much
