METHODS AND ARRANGEMENTS FOR POSITIONING IN WIRELESS COMMUNICATIONS SYSTEMS
First Claim
1. A method of reporting hidden sector information from a base station node in a wireless communication system, said base station node being an omni base station node with an internal multi-sector structure that is hidden from the rest of the system, and said hidden sector information comprising sector information of said multi-sector structure that is hidden from the rest of the system and only internally available in said omni base station, and said method comprising:
- obtaining, in said base station node, enhanced cell-ID measurements associated with a first user equipment communicating with said base station node;
formatting in said base station node, said obtained enhanced cell-ID measurements into information elements of a measurement report, each such information element comprising a plurality of symbols;
retrieving in said base station node, hidden sector information for said first user equipment, said hidden sector information comprising an indication of an antenna sector of said base station in which said first user equipment is located;
encoding in said base station node, said retrieved one of dormant and latent sector information using at least one selected symbol of said plurality of symbols of said measurement report to provide a transformed measurement report; and
reporting from said base station node, said transformed measurement report.

Abstract
A method of reporting hidden sector information from a base station node in a wireless communication system. The base station node has an internal multi-sector structure that is hidden from the rest of the system. The hidden sector information has sector information of the multi-sector structure is only internally available in the base station node. Enhanced cell-ID measurements associated with a first user equipment communicating with the base station are obtained, and formatted into information elements of a measurement report, each such information element having a plurality of symbols. Subsequently, hidden sector information for the first user equipment is retrieved and has an indication of an antenna sector of the base station in which the first user equipment is located. The retrieved dormant/latent sector information uses at least one selected symbol of the plurality of symbols of the measurement report to provide a transformed measurement report.
