Narrative:

Distance from gate to active runway about 300 yds. Ground had us contact tower from pushback area. Very busy with weight and balance, checklist, FMC, etc. I understood taxi into position and hold, which I did after looking to east for inbnds. First officer later said the clearance was for another aircraft on the south side of the airport since the tower was combined operation. First officer thought we were supposed to hold short, but didn't see what we were doing due to cockpit workload. As I started onto the runway, about 1/2 plane onto runway, tower cleared us into position to hold. I think I should pay more attention when at a large multi runway airport when the other plane on another takeoff runway maybe 1 1/2 mi away and otherwise not in sight making me believe the clearance must be for me, since I'm the only plane here. Would be helpful if the tower also advised of their combined up frequencys. Also when the other plane on the other runway 1 1/2 mi away acknowledges the clearance, you don't hear him, since he's on another frequency.

Title: UNAUTH RWY ENTRY.

Narrative: DISTANCE FROM GATE TO ACTIVE RWY ABOUT 300 YDS. GND HAD US CONTACT TWR FROM PUSHBACK AREA. VERY BUSY WITH WT AND BAL, CHKLIST, FMC, ETC. I UNDERSTOOD TAXI INTO POS AND HOLD, WHICH I DID AFTER LOOKING TO E FOR INBNDS. F/O LATER SAID THE CLRNC WAS FOR ANOTHER ACFT ON THE S SIDE OF THE ARPT SINCE THE TWR WAS COMBINED OPERATION. F/O THOUGHT WE WERE SUPPOSED TO HOLD SHORT, BUT DIDN'T SEE WHAT WE WERE DOING DUE TO COCKPIT WORKLOAD. AS I STARTED ONTO THE RWY, ABOUT 1/2 PLANE ONTO RWY, TWR CLRED US INTO POS TO HOLD. I THINK I SHOULD PAY MORE ATTN WHEN AT A LARGE MULTI RWY ARPT WHEN THE OTHER PLANE ON ANOTHER TKOF RWY MAYBE 1 1/2 MI AWAY AND OTHERWISE NOT IN SIGHT MAKING ME BELIEVE THE CLRNC MUST BE FOR ME, SINCE I'M THE ONLY PLANE HERE. WOULD BE HELPFUL IF THE TWR ALSO ADVISED OF THEIR COMBINED UP FREQS. ALSO WHEN THE OTHER PLANE ON THE OTHER RWY 1 1/2 MI AWAY ACKNOWLEDGES THE CLRNC, YOU DON'T HEAR HIM, SINCE HE'S ON ANOTHER FREQ.
