A mobile telemetry system including a mobile telemetry unit (MTU) including: a sensor for detecting a physiological signal; and a controller configured to: communicate with a mobile station (MS) to perform a clock synchronization with a clock of the MS; obtain the physiological signal from the sensor and form physiological information; determine whether a time stamped transmit information request (TS-XReq) including time stamp information (TS) was received from the MS; and generate and transmit physiological information which corresponds in time with the received TS when it is determined that the TS-XReq was received from the MS.
