My initial radio call was made 6 SE and I was informed of multiple inbound traffic to the airport. The first being a Mooney on a practice approach to 22 which was the runway in use at the time. There was also a Cessna on the downwind for 22; an auto gyro behind me; and a [turboprop aircraft] waiting to back taxi. The Mooney stated he was going to eventually break off his approach and join the pattern. However he did not state how he would join the pattern. I assumed he would go missed and do a complete pattern i.e.; upwind crosswind to downwind. I made another position report about a mile before turning downwind for 22. When I went to turn downwind I saw the Mooney come down in front of me and pass right to left. At the same time another aircraft made a radio call asking if I saw the Mooney. When I saw the Mooney I immediately turned right and made a call saying I was going to do a right 360 for spacing; I had seen the Mooney; and I would come in behind the auto gyro now. I believe the reason for the near miss was that the Mooney's strange pattern entry as he broke off flew opposite direction in downwind above the traffic pattern altitude then did a descending 180 to enter the downwind. However; I should have clarified with the Mooney how he would break off his approach and join the pattern. Neither of us saw each other until the last moment as he was a low wing above a high wing airplane which limited visibility. This incident can be prevented in the future by better position reports and stating you exact intentions while also sticking to common and correct pattern entries.
