Abstract (en)
[origin: GB2581480A] Determining a position of a user equipment, UE, in a network. A method comprises measuring, via a downlink, DL, and/or an uplink, UL, a first measurement of a set of measurements, and further comprises estimating, at least in part, the position of the UE using the first measurement of the set of measurements. Optionally, the measurement comprises measuring via the downlink: reference signal time difference, RSTD, between neighbour transmission / reception points, TRP, and reference TRP; a RSTD between a first beam and a reference beam; RSTD between a first positioning reference signal, PRS, and a reference PRS, or between a first PRS set and reference PRS set; and/or a PRS reference signal received power, RSRP. The measurement may also comprise measuring via the uplink: a relative time of arrival, RTOA, of sounding reference signals, SRS; a PRS RSRP; a TRP receive - transmit time difference; and/or a UE receive - transmit time difference. A quality metric for a receive – transmit time difference, RSTD or RTOA may be calculated, possibly using RSRP.
