20160080106 | METHOD FOR ASSIGNING PRS MUTING PATTERNS FOR RSTD MEASUREMENT ACQUISITION - One or more sequences of binary values may be generated based on a length L and a duty cycle D, wherein duty cycle D denotes a percentage of a number of bits of value one in length L. Then, based on an identity of a cell, a sequence may be selected for use by a base station in muting its transmission of a positioning signal. The sequence which is selected may be used directly in muting with no change therein, or may be elongated followed by use of an elongated sequence in muting. When specific occasions are muted in the positioning signal, a mobile device may measure times of arrival of other positioning signals that are not muted. Two such measurements of arrival times may be used to compute a difference there between, for use as a difference measurement in a procedure to determine a location of the mobile device. | 03-17-2016 |
