MA-UNITDATA.indication

5.2.3 MA-UNITDATA.indication

5.2.3.1 Function
This primitive defines the transfer of an MSDU from the MAC sublayer entity to the LLC sublayer entity, or
entities in the case of group addresses. In the absence of error, the contents of the data parameter are
logically complete and unchanged relative to the data parameter in the associated MA-UNITDATA.request
primitive.
5.2.3.2 Semantics of the service primitive
The parameters of the primitive are as follows:
MA-UNITDATA.indication(
source address,
destination address,
routing information,
data,
reception status,
priority,
service class
)
The SA parameter is an individual address as specified by the SA field of the incoming frame.
The DA parameter is either an individual or a group address as specified by the DA field of the incoming
frame.
The routing information parameter specifies the route that was used for the data transfer. The MAC sublayer
entity shall set this field to null.

The data parameter specifies the MSDU as received by the local MAC entity.
The reception status parameter indicates the success or failure of the received frame for those frames that
IEEE Std 802.11 reports via a MA-UNITDATA.indication primitive. This MAC always reports “success”
because all failures of reception are discarded without generating MA-UNITDATA.indication primitive.
The priority parameter specifies the receive processing priority that was used for the data unit transfer. The
allowed values of priority are described in 5.1.1.4.
The service class parameter specifies the receive service class that was used for the data unit transfer. The
allowed values of service class are described in 5.1.1.5 and 5.1.3.
