Abstract
Methods and apparatus for controlling signal measurements in a wireless device with receiver beamforming capability. In an embodiment, the method is performed by a wireless device and includes providing a first indication to a radio node of how the wireless device performs or will perform receiver beamforming, and performing receiver beamforming as part of a signal measurement procedure in accordance with the first indication of how the wireless device performs or will perform receiver beamforming.
Claims17
A method for controlling signal measurements in a wireless device with receiver beamforming capability, the method being performed by the wireless device and comprising:
- providing a first indication to a radio node of how the wireless device performs or will perform receiver beamforming;
- providing a second indication to the radio node of a measurement requirement the wireless device is able to meet, the measurement requirement being determined based on how the wireless device performs or will perform receiver beamforming, wherein the measurement requirement comprises at least one of:
- an association between a number of receive beam sweeps required for performing a measurement and one or more of:
- (i) a signal level, (ii) a signal quality, and a (iii) carrier frequency or frequency range,
- a number of beam sweeps required for certain types of measurements, and
- a number of receive beam sweeps required for measurements as a function of a number of carrier frequencies on which the measurements are to be performed;
- performing receiver beamforming as part of a signal measurement procedure in accordance with the first indication of how the wireless device performs or will perform receiver beamforming and the second indication of the measurement requirement.
