Abstract
A method determining a timing of an uplink signal includes receiving timing information associated with an uplink signal and a numerology of the uplink signal, wherein the timing information is used to determine a reference time of the uplink signal received from a user equipment (UE), receiving, from the UE, the uplink signal, wherein the receiving is in accordance with the timing information and the numerology of the uplink signal, and measuring an uplink relative time of arrival in accordance with the received uplink signal and the reference time of the uplink signal.
Claims28
A method, comprising:
- receiving, by a measuring device, timing information associated with an uplink signal and a numerology of the uplink signal, wherein the timing information is used to determine a reference time of the uplink signal received from a user equipment (UE);
- receiving, by the measuring device from the UE, the uplink signal in accordance with the timing information and the numerology of the uplink signal;
- and
- measuring, by the measuring device, an uplink relative time of arrival (UL RTOA) in accordance with the uplink signal and the reference time of the uplink signal, wherein the UL RTOA is a difference between the reference time of the uplink signal and a time of a start of a subframe containing the uplink signal.

A method, comprising:
- determining, by an apparatus, timing information associated with an uplink signal and a numerology of the uplink signal, wherein the timing information is used to determine a reference time of the uplink signal sent by the apparatus;
- and
- transmitting, by the apparatus to a measuring device, the uplink signal in accordance with the timing information and the numerology of the uplink signal,
- wherein the uplink signal and the reference time of the uplink signal are used to measure an uplink relative time of arrival (UL RTOA), and
- wherein the UL RTOA is a difference between the reference time of the uplink signal and a time of a start of a subframe containing the uplink signal.
2 more elements
A measuring device, comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the at least one processor, the programming including instructions to:
- receive timing information associated with an uplink signal and a numerology of the uplink signal, wherein the timing information is used to determine a reference time of the uplink signal received from a user equipment (UE);
- receive, from the UE, the uplink signal in accordance with the timing information and the numerology of the uplink signal;
- and
- measure an uplink relative time of arrival (UL RTOA) in accordance with the uplink signal and the reference time of the uplink signal, wherein the UL RTOA is a difference between the reference time of the uplink signal and a time of a start of a subframe containing the uplink signal.
