Abstract
There is provided mechanisms for reporting a faulty antenna port at a transmitting radio device. A method is performed by a receiving radio device. The method comprises receiving at least one reference signal transmitted at an antenna port of the transmitting radio device. The method comprises determining whether the antenna port is deemed faulty or not by subjecting the at least one reference signal to an evaluation criterion. The method comprises transmitting, when the antenna port is deemed faulty, a report to the transmitting radio device. The report indicates that the antenna port is deemed faulty.
Claims29
A method for reporting a faulty antenna port at a transmitting radio device, the method comprising a receiving radio device:
- receiving at least one reference signal transmitted at an antenna port of the transmitting radio device;
- determining whether the antenna port is deemed faulty or not by subjecting the at least one reference signal to an evaluation criterion;
- and
- transmitting, when the antenna port is deemed faulty, a report to the transmitting radio device, the report indicating that the antenna port is deemed faulty.
A method for receiving reporting of a faulty antenna port at a transmitting radio device, the method comprising the transmitting radio device:
- transmitting at least one reference signal at an antenna port of the transmitting radio device;
- and
- receiving a report from a receiving radio device having received the at least one reference signal, wherein the report indicates that the antenna port is deemed faulty by the receiving radio device.
A radio device, acting as a receiving radio device, for reporting a faulty antenna port at a transmitting radio device, the radio device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the radio device is operative to:
- receive at least one reference signal transmitted at an antenna port of the transmitting radio device;
- determine whether the antenna port is deemed faulty or not by subjecting the at least one reference signal to an evaluation criterion;
- and
- transmit, when the antenna port is deemed faulty, a report to the transmitting radio device, the report indicating that the antenna port is deemed faulty.
A radio device, acting as a transmitting radio device, for receiving reporting of a faulty antenna port at the transmitting radio device, the radio device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the radio device is operative to:
- transmit at least one reference signal at an antenna port of the transmitting radio device;
- and
- receive a report from a receiving radio device having received the at least one reference signal, wherein the report indicates that the antenna port is deemed faulty by the receiving radio device.
A non-transitory computer readable recording medium storing a computer program product for reporting a faulty antenna port at a transmitting radio device, the computer program product comprising software instructions which, when run on processing circuitry of a radio device acting as a receiving radio device, causes the radio device acting as a receiving radio device to:
- receive at least one reference signal transmitted at an antenna port of the transmitting radio device;
- determine whether the antenna port is deemed faulty or not by subjecting the at least one reference signal to an evaluation criterion;
- and
- transmit, when the antenna port is deemed faulty, a report to the transmitting radio device, the report indicating that the antenna port is deemed faulty.
A non-transitory computer readable recording medium storing a computer program product for receiving reporting of a faulty antenna port at a transmitting radio device, the computer program product comprising software instructions which, when run on processing circuitry of a radio device acting as the transmitting radio device, causes the radio device acting as the transmitting radio device to:
- transmit at least one reference signal at an antenna port of the transmitting radio device;
- and
- receive a report from a receiving radio device having received the at least one reference signal, wherein the report indicates that the antenna port is deemed faulty by the receiving radio device.
