The higher layer processor 1623 may manage physical layer's behaviors (the DL transmitter's and the UL receiver's behaviors) and provide higher layer parameters to the physical layer. The higher layer processor 1623 may obtain transport blocks from the physical layer. The higher layer processor 1623 may send/acquire higher layer messages such as an RRC message and MAC message to/from a UE's higher layer. The higher layer processor 1623 may provide the PDSCH transmitter transport blocks and provide the PDCCH transmitter transmission parameters related to the transport blocks.
The DL transmitter 1625 may multiplex downlink physical channels and downlink physical signals (including reservation signal) and transmit them via transmission antennas 1631. The UL receiver 1633 may receive multiplexed uplink physical channels and uplink physical signals via receiving antennas 1631 and de-multiplex them. The PUCCH receiver 1635 may provide the higher layer processor 1623 UCI. The PUSCH receiver 1637 may provide the higher layer processor 1623 received transport blocks.
