Abstract: 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.

Abstract: Systems, methods and apparatus for using positioning modes including mobile-based and network-based positioning modes are presented. The mobile device comprises a transceiver configured to receive an individualized command from a server instructing the mobile device to switch from the first positioning mode to the second positioning mode. The individualized command is based on at least one of: (1) a determined accuracy of the mobile device; (2) a state of a resource; (3) a comparison between a network load and a threshold; (4) a geo-fence; or (5) a combination thereof. The mobile device also comprises a processor coupled to the transceiver, wherein the processor is configured to: operate in the first positioning mode before receiving the individualized command; switch from the first positioning mode to the second positioning mode based on the individualized command from the server; and operate in the second positioning mode after receiving the individualized command.
