Abstract
A positioning estimate for a user equipment (UE) is determined based on a combination of uplink-based positioning and downlink-based positioning. Positioning measurements based on downlink signals and uplink signals can be utilized to determine the positioning estimate. The positioning estimate may be computed by the UE or a node of a wireless communications network. This positioning scheme can include two parts, where a first part and second part are either uplink-based or downlink-based, but the two parts are different from each other. Positioning measurements performed in the first part may be sent along with reference signals in the second part.
Claims22
A method for positioning of a wireless communications device performed by a network node, comprising:
- determining resources for use when positioning the wireless communication device using a combination of uplink-based and downlink-based positioning, wherein the resources comprise resources for uplink-based positioning and resources for downlink-based positioning;
- and
- transmitting, to the wireless communication device, positioning configuration information indicative of the determined resources and a timing relationship between first positioning measurements and second positioning measurements.
(canceled)
A method for facilitating positioning of a wireless communications device, comprising:
- receiving, from a network node, positioning configuration information indicative of resources for use when positioning the wireless communication device (100) using a combination of uplink-based and downlink-based positioning and a timing relationship between the uplink-based and the downlink-based positioning, wherein the resources comprise resources for uplink-based positioning and resources for downlink-based positioning and the positioning configuration information indicates the resources in accordance with the timing relationship;
- transmitting uplink reference signals to one or more network nodes according to the resources for uplink-based positioning;
- receiving one or more downlink reference signals from the one or more network nodes according to the resources for downlink-based positioning;
- and
- measuring a positioning parameter based on the one or more downlink reference signals.
