AIR INTERFACE FOR FIXED BROADBAND WIRELESS ACCESS SYSTEMS

IEEE Std 802.16-2001

6.1.1.9.4 Effect of receipt

The receipt of this primitive informs the convergence entity that a connection has been terminated. The convergence entity shall no longer use this CID for data transmission.

6.1.1.10 MAC_DATA.request

6.1.1.10.1 Function

This primitive defines the transfer of data to the MAC entity from a CS SAP.

6.1.1.10.2 Semantics of the service primitive

The parameters of the primitive are as follows:

MAC_DATA.request

(

Connection ID, length,

data, discard-eligible flag, encryption flag

)

The Connection ID parameter specifies the connection over which the data is to be sent; the service class is implicit in the Connection ID.

The length parameter specifies the length of the MAC SDU in bytes.

The data parameter specifies the MAC SDU as received by the local MAC entity.

The discard-eligible flag specifies whether the MAC SDU is to be preferentially discarded in the event of link congestion and consequent buffer overflow.

The encryption flag specifies that the data sent over this connection is to be encrypted, if ON. If OFF, then no encryption is used.

6.1.1.10.3 When generated

This primitive is generated by a CS whenever a MAC SDU is to be transferred to a peer entity or entities.

6.1.1.10.4 Effect of receipt

The receipt of this primitive causes the MAC entity to process the MAC SDU through the MAC sublayer and pass the appropriately formatted PDUs to the PHY transmission CS for transfer to peer MAC sublayer entities, using the CID specified.

6.1.1.11 MAC_DATA.indication

6.1.1.11.1 Function

This primitive defines the transfer of data from the MAC to the CS. The specific CS to receive the indicate message is implicit in the CID.
