Positioning node, user equipment and methods therein
First Claim
1. A method in a positioning node for enabling positioning of a user equipment, which user equipment is served in a first cell controlled by a radio network node, which positioning node and radio network node are comprised in a radio communications network, the method comprising;
- obtaining an indication indicating availability, at the user equipment, of timing information of at least one cell; and
determining whether the timing information of the at least one cell is available at the user equipment based on the obtained indication, which timing information is enabling positioning of the user equipment;
generating positioning assistance data, which positioning assistance data comprises information associated with the at least one cell;
transmitting a message to the user equipment, which message comprises the positioning assistance data, which positioning assistance data and the timing information of the at least one cell available at the user equipment enables positioning of the user equipment;
wherein the generated positioning assistance data comprises an indication of a reference cell and a list of neighbour cells and information regarding muting sequence of at least some of the cells.

Abstract
Embodiments herein relate to a method in a positioning node for enabling positioning of a user equipment, which user equipment is served in a first cell controlled by a radio network node. The positioning node and radio network node are comprised in a radio communications network. The positioning node obtains an indication indicating availability, at the user equipment, of timing information of at least one cell. The positioning node further determines whether the timing information of the at least one cell is available at the user equipment based on the obtained indication, which timing information is enabling positioning of the user equipment.

11. The method in a user equipment for enabling positioning of the user equipment, which user equipment and a positioning node are comprised in a radio communications network, the method comprising;
-
transmitting, to the positioning node, an indication indicating availability, at the user equipment, of timing information of at least one cell, which timing information is enabling positioning of the user equipment; receiving, from the positioning node, a message comprising positioning assistance data, which positioning assistance data comprises information associated with the at least one cell for which the timing information is known or is obtainable by the user equipment, which at least one cell is the cell indicated with the available timing information in the transmitted indication; performing a positioning measurement using the positioning assistance data and the available timing information of the at least one cell to enable positioning of the user equipment; and wherein the performing the positioning measurement comprises determining a timing of a muting sequence of another cell, being different than the at least one cell, in the positioning assistance data based on the timing information and information regarding the at least one cell in the received positioning assistance data. - View Dependent Claims (12, 13, 14, 15, 16, 17)
