Narrative:

I was inbound to land. On initial contact with prc tower on 128.75, I was requested to report on a 6 mi 45 for right traffic runway 21. Upon reporting the 6 mi 45, I was instructed to contact prc tower on 125.3. On the third attempt to raise the tower, they responded and requested I report at 2 mi on the 45. Upon reporting the 2 mi 45 I was instructed to report downwind abeam the tower. While entering on the 45 I scanned for traffic several times (lifting my right wing each time) looking to the crosswind and downwind sections of the pattern. Just before I was about to turn downwind I saw the other plane at my 1-2 O'clock position and lower. I made a climbing left turn and informed the tower that I would be staying outside of the traffic and that I would be following it. I was never advised of the traffic. I never heard the traffic advised of me, and I never heard any communications between the traffic and the tower that would have called my attention to the position of the other aircraft. After landing, I talked with the pilot of the other aircraft. He was doing touch and go's (solo) and said he was never advised either and began a descent to about 5800' (tpa = 6000') when he saw we were getting close.
