VARYING PROCESSES TO CONTROL TRANSMISSION CHARACTERISTICS FOR POSITION DETERMINATION OPERATIONS |
摘要 |
Disclosed are systems, apparatus, devices, methods, media, products, and other implementations, including a method that includes determining, at a first wireless device comprising multiple transmit antennas, at least one signal transmission characteristic according to at least one pre-determined varying transmission characteristic determination process. The at least one transmission characteristic includes, for example, a transmit antenna selected from the multiple transmit antennas, a beam characteristic, a cyclic delay diversity parameter, and/or any combination thereof. The method also includes transmitting from the first wireless device to a second wireless device a signal using the at least one signal transmission characteristic determined according to the at least one pre-determined varying transmission characteristic determination process. The transmitted signal is configured to facilitate position determination of the second wireless device upon deriving at the second wireless device a reconstructed value of the at least one signal transmission characteristic determined at the first wireless device. |

1. A method comprising:
determining, at a first wireless device comprising multiple transmit antennas, at least one signal transmission characteristic according to at least one pre-determined varying transmission characteristic determination process, the at least one signal transmission characteristic including: a transmit antenna selected from the multiple transmit antennas, a beam characteristic, a cyclic delay diversity parameter, or any combination thereof; and transmitting, from the first wireless device to a second wireless device, a signal using the at least one signal transmission characteristic determined according to the at least one pre-determined varying transmission characteristic determination process, the transmitted signal configured to facilitate position determination of the second wireless device upon deriving at the second wireless device a reconstructed value of the at least one signal transmission characteristic determined at the first wireless device. |
