B737 MOVES FORWARD TO ALLOW COMPANY ACCESS TO THE GATE TO WHICH CLRED AND IS CHALLENGED BY RDU GND CTL.

Narrative

WE PUSHED BACK FROM GATE AT RDU AND WERE CLR OF TXWY A. WHEN WE WERE READY FOR TAXI; WE COULD NOT GET A RADIO CALL IN; AS GND CTL WAS BUSY. COMPANY LANDED ON RWY 5R AND WAS HOLDING SHORT OF TXWY A ON TXWY C. 2 LIGHT ACFT WERE HOLDING ON TXWY D SHORT OF TXWY A. GND CLRED COMPANY TO THE GATE; WHICH WE HAD BLOCKED; WHEN A B727 (WHICH WAS NEBOUND ON TXWY A) WENT BY. THE B727 WENT BY; AND SINCE COMPANY COULD NOT GET TO THE GATE UNTIL WE MOVED; I FELT THAT GND WOULD WANT US TO HEAD SW ON TXWY A SINCE HE HAD ALREADY CLRED COMPANY TO OUR GATE. AS I STARTED TO MOVE OUR ACFT; MY FO REMINDED ME THAT WE WERE NOT CLRED ONTO TXWY A. I CONCURRED AND FELT THAT I COULD STILL MOVE CLR OF THE GATE AND REMAIN CLR OF TXWY A. GND CTL CALLED AND ADVISED THAT WE WERE NOT CLRED ONTO TXWY A. REPLIED 'THAT IS CORRECT; WE ARE NOT CLRED ONTO TXWY A.' GND THEN GAVE US TAXI INSTRUCTIONS TO RWY 5L. IT IS MY BELIEF THAT WE REMAINED CLR OF TXWY A; AS THAT WAS MY INTENTION. HOWEVER; IN THE FUTURE AT RDU; I PLAN ON REMAINING STATIONARY UNTIL TAXI INSTRUCTIONS ARE RECEIVED.
