Abstract: A method (500) is performed by a wireless device (710). The method comprises transmitting (540) an uplink signal (730). A time offset (820) is employed for the uplink signal. The time offset is based on an estimated filter delay (812, 813, 814, 815) and an estimated distance between the wireless device and a network node (720). The estimated filter delay is associated with one or more filters (712, 714, 722, 724) of the wireless device and/or of the network node. In some embodiments, the time offset is also based on an estimated radio channel delay (816) of a radio channel between the wireless device and the network node relative to the delay of a line of sight, LOS, path between the wireless device and the network node. In some embodiments, the wireless device receives an indication (760) that the wireless device is to determine the time offset.

Abstract: A method may be performed for positioning of a wireless device (14). The method comprises obtaining, for each of one or more radio network nodes (12-1, 12-2), a result of a signal measurement performed by the wireless device (14) on a beam that, according to spatial characteristics of different beams transmitted by the radio network node and/or according to signal measurement analysis, provides the most direct signal path from the radio network node to the wireless device (14). The method may also include using the result obtained for each of the one or more radio network nodes (12-1, 12-2) in a positioning procedure for determining a position of the wireless device (14).

Abstract: According to some embodiments, a method performed by a wireless device for transmitting on a plurality of antennas comprises signaling, to a network node, a wireless device power transmission capability. The wireless device power transmission capability identifies a power ratio value of a plurality of power ratio values that the wireless device supports for transmission of a physical uplink channel. Each value of the plurality of power ratio values corresponds to a transmission power capability and to a number of antenna ports. A power ratio refers to a ratio relative to a maximum power the wireless device is rated to transmit. The method further comprises transmitting a physical uplink channel using the 0 number of antenna ports with a power scaled at least by the power ratio value.
