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.
Claims20
A method, comprising:
- receiving, by an access node, timing information associated with an uplink (UL) signal and a numerology associated with the UL signal, wherein the timing information comprises a radio frame initialization time indicating a start time of a radio frame number zero;
- receiving, by the access node from a user equipment (UE), the UL signal in accordance with the timing information and the numerology;
- and
- measuring, by the access node, a UL relative time of arrival (RTOA) in accordance with the UL signal and a reference time of the UL signal, wherein the UL RTOA is a difference between the reference time of the UL signal and an actual start time of a subframe containing the UL signal, wherein the reference time is determined in accordance with the start time of the radio frame number zero and the subframe containing the UL signal.

A method, comprising:
- obtaining, by a user equipment (UE), configuration of an uplink (UL) signal and a numerology of the UL signal;
- and
- transmitting, by the UE, the UL signal in accordance with the configuration and the numerology,
- wherein the UL signal and a reference time of the UL signal are used to measure a UL relative time of arrival (RTOA), the UL RTOA is a difference between the reference time and an actual start time of a subframe containing the UL signal, the reference time is determined in accordance with timing information comprising a radio frame initialization time indicating a start time of a radio frame number zero and the subframe containing the UL signal.

An apparatus, comprising:
- at least one processor coupled with a non-transitory computer-readable medium storing instructions that, when executed by the at least one processor, cause the apparatus to perform operations including:
- receiving timing information associated with an uplink (UL) signal and a numerology associated with the UL signal, wherein the timing information comprises a radio frame initialization time indicating a start time of a radio frame number zero;
- receiving, from a user equipment (UE), the UL signal in accordance with the timing information and the numerology;
- and
- measuring a UL relative time of arrival (RTOA) in accordance with the UL signal and a reference time of the UL signal, wherein the UL RTOA is a difference between the reference time of the UL signal and an actual start time of a subframe containing the UL signal, wherein the reference time is determined in accordance with the start time of the radio frame number zero and the subframe containing the UL signal.
