|
||||
*@ingroup w3g4f_mac_layer_
|
||||
*@{
|
||||
|
||||
This subclause describes the primitives for communications between the MAC and PHY sub-layers.
|
||||
|
||||
The primitives for dynamic MAC-PHY PDU exchange (Transport channel interface) are:
|
||||
|
||||
- MACPHY_DATA_REQ: transfers or requests a PDU from PHY. The data is passed along with the dynamic PHY transmission
|
||||
format (coding and modulation, time/freq/space resource allocation)
|
||||
|
||||
- MACPHY_DATA_IND: Function call (by PHY) to deliver a new PDU and corresponding measurements to MAC. This implicitly confirms the MACPHY_DATA_REQ by
|
||||
filling the fields of the request (TX or RX) with the data and measurements.
|
||||
|
||||
One primitive is used for semi-static configuration (during logical channel establishment)
|
||||
relaying the puncturing/repetition patterns for HARQ:
|
||||
|
||||
- MACPHY_CONFIG_SACH_HARQ_REQ (still to be defined...)
|
||||
|
||||
The primitive for static (re)configuration is:
|
||||
- MACPHY_CONFIG_REQ : This primitive transports the initial configuration during the setup phase of equipment, both for CH and UE.
|
||||
Static configuration is used during the initialization phase of the equipment. For a CH, it is done prior to any communication. For a UE, some
|
||||
structures may be set after receiving configuration information from the network via the BCCH/CCCH.
