IEEE Std 802.16-2001

LOCAL AND METROPOLITAN AREA NETWORKS—PART 16:

The automatic repeat request (ARQ) parameters are: whether or not ARQ is used for the connection, maximum retransmission limit, and acknowledgment window size. The sequence number is used to correlate this primitive with its response from the BS via the MAC.

6.1.1.1.3 When generated

This primitive is generated by a CS of a BS or SS unit to request the BS to set up a new connection.

6.1.1.1.4 Effect of receipt

If the primitive is generated on the SS side, the receipt of this primitive causes the MAC to pass the request (in the form of a dynamic service addition—request message) to the MAC entity in the BS. The SS MAC remembers the correlation between sequence number and the requesting convergence entity.

If the primitive is generated on the BS side, the BS checks the validity of the request and, if valid, chooses a CID and includes it in the Dynamic Service Addition—Request message (6.2.13.8.3) sent to the SS. This CID shall be returned to the requesting CS via the CONFIRM primitive. If the primitive originated at the SS, the actions of generating a CID and authenticating the request are deferred to the INDICATION/RESPONSE portion of the protocol.

6.1.1.2 MAC_CREATE_CONNECTION.indication

6.1.1.2.1 Function

This primitive is sent by the noninitiating MAC entity to the CS, to request the dynamic addition of a connection in response to the MAC sublayer receiving a Dynamic Service Addition—Request message. If the noninitiating MAC entity is at the base station, a CID is generated and the request is authenticated.

6.1.1.2.2 Semantics of the service primitive

The parameters of the primitive are as follows:

MAC_CREATE_CONNECTION.indication

(

service type, convergence sublayer, service flow parameters, sequence number

)

Parameters: see MAC_CREATE_CONNECTION.request. The encryption and CRC flags are not delivered with the.indication primitive since they will have already been acted on by lower layers, to decrypt the data or to check a CRC, before the MAC SDU is passed up to the CS.

6.1.1.2.3 When generated

This primitive is generated by the MAC sublayer of the noninitiating side of the protocol when it receives a Dynamic Service Addition—Request message from the initiating side of the connection.

6.1.1.2.4 Effect of receipt

When the CS receives this primitive, it checks the validity of the request from the point of view of its own resources. It accepts or rejects the request via the MAC_CREATE_CONNECTION.response primitive.
