Abstract
Methods and devices for performing hybrid fingerprinting/observed time difference of arrival (OTDOA) positioning are described. Fingerprinting information can be used to improve OTDOA results by using the fingerprinting information to generate OTDOA assistance information. The OTDOA assistance information is sent to a user equipment, which uses the OTDOA assistance information to perform reference signal time differences (RSTDs) measurements.
