<p>A method (100, 800), access point device (200, 300, 500, 600) and a plurality of peripheral devices (400, 700) provide for controlling a space diversity switch in a time division duplex system. The method includes: inputting data to a peripheral; generating a CRC1 in a peripheral; transmitting the data and the CRC1; receiving, by an access point device, the data with the CRC1; extracting CRC1 and generating CRC2 from received data; determining whether CRC1 and CRC2 are equal and where CRC1 and CRC2 are equal, failing to generate a repeat request; where CRC1 and CRC2 are unequal, generating a repeat request; determining whether a number of requests = N; where the number of requests N, incrementing a counter and returning to receiving the data with the CRC1; and where the number of requests = N, resetting the counter, changing an antenna state and returning to receiving, by an access point device, the data with the CRC1.</p> |
