1. A method, performed by a network node, for providing positioning assistance data to one or more user equipment (UEs) in a wireless network, the method comprising:
determining an angular resolution of angular positioning assistance data for each particular beam of a plurality of beams transmitted by one or more transmission reception points (TRPs) in the wireless network; and
transmitting, to one or more UEs, the angular positioning assistance data for the plurality of beams, wherein for each particular beam the angular positioning assistance data includes:
a first part having a first resolution; and
when the determined angular resolution for the particular beam is greater than the first resolution, a second part having a second resolution that is greater than the first resolution.
