Abstract
A method and apparatus include receiving a measurement configuration by higher layer signaling, where the higher layer signaling is above the physical layer. The measurement configuration includes at least information of frequency location of synchronization signals, a carrier frequency, and a maximum allowed measurement bandwidth. A measurement reference signal is then received based on the received measurement configuration, and a measurement based on the received measurement reference signal is performed.
Claims20
A method in a user equipment in a communication network, the method comprising:
- receiving a measurement configuration by higher layer signaling, where the higher layer signaling is above the physical layer, wherein the measurement configuration includes at least information of a frequency location of synchronization signals, a carrier frequency value, and a measurement bandwidth;
- detecting synchronization signals on the frequency location of synchronization signals included in the measurement configuration;
- determining a first identity value from the detected synchronization signals;
- receiving a broadcast channel including a first reference signal based on the determined first identity value;
- determining a second identity value from the received broadcast channel;
- receiving a second reference signal based on the first identity value, the second identity value, the frequency location of synchronization signals, the carrier frequency value, and the measurement bandwidth;
- and
- performing a measurement based on the received second reference signal.
A user equipment in a communication network, the user equipment comprising:
- a transceiver that sends and receives signals between the user equipment and a communication network entity including receiving a measurement configuration by higher layer signaling, where the higher layer signaling is above the physical layer, wherein the measurement configuration includes at least information of a frequency location of synchronization signals, a carrier frequency value, and a measurement bandwidth;
- and
- a controller that detects synchronization signals on the frequency location of synchronization signals included in the measurement configuration and determines a first identity value from the detected synchronization signals;
- wherein the transceiver further receives a broadcast channel including a first reference signal based on the determined first identity value, and a second reference signal based on the first identity value, a second identity value, the frequency location of synchronization signals, the carrier frequency value, and the measurement bandwidth;
- and
- wherein the second identity value is determined from the received broadcast channel by the controller, and the controller further performs a measurement based on the received second reference signal.
