A hybrid method of estimating position of a mobile device which utilizes both received signal power and timing measurements. Received signal power of signals received by the mobile device from a plurality of cells are measured and corresponding received signal power measurements are stored. The method further includes measuring, at the mobile device, times of arrival of signals received from the plurality of cells. A plurality of time difference of arrival (TDOA) measurements are determined from the times of arrival. A power-time hybrid Gaussian maximum likelihood estimator and positioning assistance data for the plurality of cells are used to generate a maximum likelihood estimate of the position of the mobile device by evaluating a joint conditional probability of the received signal power measurements and the plurality of TDOA measurements. Gaussian random variables may be used to represent the received signal power measurements and the TDOA measurements.

A wireless communications system may support beamforming to transmit and receive signals. A device operating within the wireless communications system may transmit a request to measure a beamformed reference signal. The device may also transmit a beamforming configuration indicating one or more beamforming options for measuring the beamformed reference signal. The beamforming options may include measuring the beamformed reference signal using a directional configuration and an omni-directional configuration. The device receiving the beamforming configuration may form a receive beam in accordance with the beamforming configuration to measure the beamformed reference signal. A device operating within the wireless communications system may determine to use a particular beamforming option for measuring a beamformed reference signal without first receiving a beamforming configuration, and may make the determination based on signal quality at the device or capabilities of the device.
