Abstract
A method and a receiver device are disclosed for channel estimation of a broadcast channel. According to an embodiment, the receiver device determines a first channel estimation of demodulation reference signal (DMRS) from a transmitter device. The receiver device determines a second channel estimation of one or more synchronization related reference signals from the transmitter device. The receiver device determines a final channel estimation of a broadcast channel from the transmitter device based at least on the first and second channel estimations.
Claims21
A method implemented at a receiver device, the method comprising:
- determining a first channel estimation of demodulation reference signal, DMRS, from a transmitter device;
- determining a second channel estimation of one or more synchronization related reference signals from the transmitter device;
- and
- determining a final channel estimation of a broadcast channel from the transmitter device based at least on the first and second channel estimations.
A receiver device comprising:
- at least one processor;
- and
- at least one memory, the at least one memory containing instructions executable by the at least one processor to operate the receiver device to:
- determine a first channel estimation of demodulation reference signal, DMRS, from a transmitter device;
- determine a second channel estimation of one or more synchronization related reference signals from the transmitter device;
- and
- determine a final channel estimation of a broadcast channel from the transmitter device based at least on the first and second channel estimations.
A computer program product comprising instructions which when executed by at least one processor, cause the at least one processor to perform the following actions:
- determining a first channel estimation of demodulation reference signal, DMRS, from a transmitter device;
- determining a second channel estimation of one or more synchronization related reference signals from the transmitter device;
- and
- determining a final channel estimation of a broadcast channel from the transmitter device based at least on the first and second channel estimations.
