Method for coverage determination using predefined paths
First Claim
1. A method, performed in a wireless device, of determining radio coverage for at least one small cell base station, the method comprising:
- obtaining at least one path in an indoor environment, along which radio condition measurements are to be performed, wherein the at least one path is obtained at least based on reception of information defining the at least one path from a radio network node;
performing radio condition measurements along the at least one path;
determining position estimates along the at least one path within a predefined distance from the at least one path using location data, wherein at least some of the position estimates correspond to the radio condition measurements, wherein the location data is obtained from a direction sensor and a movement sensor of the wireless device; and
either determining radio coverage using the radio condition measurements and corresponding position estimates, or reporting the radio condition measurements and the corresponding position estimates to the radio network node for determination of radio coverage in the radio network node, wherein the wireless device determines the radio coverage upon reception of an indication from the network node to initiate determination of the radio coverage.

Abstract
The present disclosure relates to coverage monitoring and in particular it relates to determining radio coverage, e.g. for small cell deployment in a building. The disclosure relates to methods for coverage determination as well as to corresponding devices and computer programs. According to one aspect, the disclosure proposes a method, performed in a wireless device 10, of determining radio coverage. The method comprises obtaining S1 at least one path along which radio condition measurements are to be performed and performing S2 radio condition measurements along the at least one path. The method further comprises determining S3 position estimates, wherein at least some of the position estimates correspond to the radio condition measurements. The method further comprises determining S4a radio coverage using the radio condition measurements and corresponding position estimates and/or reporting S4b the radio condition measurements and the corresponding position estimates to a radio network node for determination of radio coverage in the radio network node.
