Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present disclosure provides a method performed by a user equipment (UE) for acquiring global navigation satellite system (GNSS) positioning information is provided. The method includes performing GNSS measurement to acquire the GNSS positioning information, and estimating a time-frequency offset based on the GNSS positioning information for pre-compensation of uplink transmission.
Claims20
A method performed by a user equipment (UE) for acquiring global navigation satellite system (GNSS) positioning information, the method comprising:
- receiving, from a base station, a first indication based on a first subframe, wherein the first indication indicates that the UE is triggered to perform GNSS measurement;
- identifying that the UE is triggered to perform the GNSS measurement based on the first indication;
- performing the GNSS measurement to acquire the GNSS positioning information based on a GNSS measurement window;
- and
- estimating at least one of a time offset or a frequency offset based on the GNSS positioning information for pre-compensation of uplink transmission,
- wherein a start location of the GNSS measurement window corresponds to a second subframe that is after a predefined interval from the first subframe.
A method performed by a base station for indicating to a user equipment (UE) to acquire global navigation satellite system (GNSS) positioning information, the method comprising:
- determining to trigger the UE to perform global navigation satellite system (GNSS) measurement;
- transmitting a first indication to the UE based on a first subframe, wherein the first indication indicates that the UE is triggered to perform GNSS measurement to acquire the GNSS positioning information;
- and
- receiving, from the UE, information associated with GNSS measurement,
- wherein the GNSS measurement is associated with a GNSS measurement window,
- wherein a start location of the GNSS measurement window corresponds to a second subframe that is after a predefined interval from the first subframe, and
- wherein at least one of a time offset or a frequency offset is associated with the GNSS positioning information for pre-compensation of uplink transmission.
A user equipment (UE) comprising:
- a transceiver configured to transmit and receive signals;
- and
- a processor coupled to the transceiver and configured to:
- receive, from a base station, a first indication based on a first subframe, wherein the first indication indicates that the UE is triggered to perform global navigation satellite system (GNSS) measurement,
- identify that the UE is triggered to perform the GNSS measurement based on the first indication,
- perform the GNSS measurement to acquire the GNSS positioning information based on a GNSS measurement window, and
- estimate at least one of a time offset or a frequency offset based on the GNSS positioning information for pre-compensation of uplink transmission,
- wherein a start location of the GNSS measurement window corresponds to a second subframe that is after a predefined interval from the first subframe.
A base station comprising:
- a transceiver configured to transmit and receive signals;
- and
- a processor coupled to the transceiver and configured to:
- determine to trigger a user equipment (UE) to perform global navigation satellite system (GNSS) measurement,
- transmit a first indication to the UE based on a first subframe, wherein the first indication indicates that the UE is triggered to perform the GNSS measurement to acquire GNSS positioning information, and
- receive, from the UE, information associated with the GNSS measurement,
- wherein the GNSS measurement is associated with a GNSS measurement window,
- wherein a start location of the GNSS measurement window corresponds to a second subframe that is after a predefined interval from the first subframe, and
- wherein at least one of a time offset or a frequency offset is associated with the GNSS positioning information for pre-compensation of uplink transmission.
