Abstract:
1. A method for determining a time of a beginning of a measurement time interval for carrying out a radio measurement comprising: receiving a first message via a radio communication channel, the first message including a counter value represented by one or more bits, the counter value having a first value to indicate that no measurement time interval is scheduled by the first message; receiving a second message via the radio communication channel, the second message including a counter value represented by one or more bits, the counter value having a second value to indicate that the measurement time interval begins after a pre-determined time period from a time of transmission of the second message; receiving a third message including a counter value having a third value to indicate that the second message is estimated to be transmitted after a first time period from a time of transmission of the third message; and receiving a fourth message including a counter value having a fourth value to indicate that the second message is estimated to be transmitted after a second time period from a time of transmission of the fourth message, wherein the second time period is shorter than the first time period; determining the time of the beginning of the measurement time interval based on the counter value of the second message and on the time of transmission of the second message; and carrying out the radio measurement during the measurement time interval.
