AIR INTERFACE FOR FIXED BROADBAND WIRELESS ACCESS SYSTEMS

IEEE Std 802.16-2001

RNG_REQ_VECTOR—the set of PHY parameters reflecting the transmission adjustments requested from the PHY transmitter

RNG_IND_VECTOR— the set of PHY parameters reflecting the reception quality information supplied by the PHY receiver

TXVECTOR—the set of PHY parameters related to the transmit of the PHY PDU, including Tx Power, preamble’s specification, burst profiles for each involved burst, amount of data to be transmitted at each burst, etc.

TXSTATUS—the set of PHY indicators that figure the result of the whole PHY activity triggered by the transmission request from MAC. This may include indication of the overrun/underrun events encountered during the data transfer through the PHY SAP

RXVECTOR—the set of PHY parameters related to the receipt of the expected PHY PDU, including preamble’s specification, burst profiles for each involved burst, amount of data expected to arrive in each burst, etc.

RXSTATUS—the set of PHY indicators that figure the result of the whole PHY activity triggered by the PHY_RXSTART.request from MAC. This may include indication of the received signal strength, errors encountered by forward error correction (FEC) function, overrun/underrun events encountered during the data transfer through the PHY SAP, etc.

8.1.3.3 PHY_SCHEDPARAM.request

8.1.3.3.1 Function

This primitive requests the set of PHY parameters, such as symbol duration, that are related to scheduling.

8.1.3.3.2 Semantics of the service primitive

PHY_SCHEDPARAM.request

(

SCHED_PARAM_VECTOR

)

8.1.3.3.3 When generated

Typically, this primitive is generated by the MAC each time as the set of DIUC/UIUCs and/or burst profiles associated with them have changed, e.g., on arrival and handling of the DCD/UCD message.

8.1.3.3.4 Effect of receipt

The PHY entity shall generate a PHY_SCHEDPARAM.response primitive that conveys the requested set of parameters.

8.1.3.4 PHY_SCHEDPARAM.response

8.1.3.4.1 Function

This primitive is to supply to MAC the set of PHY parameters requested by the PHY_SCHEDPARAM.request.
