Abstract
Methods, apparatuses, and devices for processing Positioning Reference Signals (PRS) bursts are presented. In one example, a mobile device may acquire a first PRS burst transmitted from a base station through first transmitter antenna port and acquire a second PRS burst transmitted from a base station through a second antenna port. The mobile device may select between the first and second acquired PRS bursts for use in positioning operations such as observed time difference of arrival.
Claims30
A method comprising, at a mobile device:
- acquiring a first Positioning Reference Signals (PRS) burst transmitted from a base station during a first occasion;
- acquiring a second PRS burst transmitted from said base station during a second occasion;
- and
- selecting between said first and second acquired PRS bursts for use in positioning operations based, at least in part, on one or more performance criteria.
A mobile device, comprising:
- a receiver to receive signals from a communications channel;
- and
- one or more processors coupled to said receiver to:
- acquire a first Positioning Reference Signals (PRS) burst received at said receiver and transmitted from a base station during a first occasion;
- acquire a second PRS burst transmitted from said base station during a second occasion;
- and
- select between said first and second acquired PRS bursts for use in positioning operations based, at least in part, on one or more performance criteria.
An article comprising:
- a non-transitory storage medium comprising machine-readable instructions stored thereon which are executable by one or more processors of a mobile device to:
- acquire a first Positioning Reference Signals (PRS) burst transmitted from a base station during a first occasion;
- acquire a second PRS burst transmitted from said base station during a second occasion;
- and
- select between said first and second acquired PRS bursts for use in positioning operations based, at least in part, on one or more performance criteria.
A mobile device, comprising:
- means for acquiring a first Positioning Reference Signals (PRS) burst transmitted from a base station during a first occasion;
- means for acquiring a second PRS burst transmitted from said base station during a second occasion;
- and
- means for selecting between said first and second acquired PRS bursts for use in positioning operations based, at least in part, on one or more performance criteria.
