8.1.3.17 PHY_TXSTART.request

8.1.3.17.1 Function

This primitive requests the PHY to start the PHY PDU transmission and carries all the control information needed for the corresponding PHY, such as start and end times of transmission and PHY parameters for multiple bursts, types of preambles, etc.

8.1.3.17.2 Semantics of the service primitive

PHY_TXSTART.request

(

TXVECTOR

)

8.1.3.17.3 When generated

This primitive is generated by the MAC to initiate PHY PDU transmission.
