Abstract
Disclosed is a method of providing a positional reference signal in a communication system comprising the step of: providing a positional reference signal which is configurable in both time and frequency domains. Also disclosed is a method of configuring a periodicity of a positioning reference signal transmission in a communication system comprising the step of configuring the starting timing and the duration of the positioning reference signal transmission, wherein the transmission is either consecutive or interleaved on cell or cell group basis, and the configuration is numerology dependent.
Claims20
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting positioning reference signal (PRS) configuration information,
- wherein the PRS configuration information defines a first time period between two instances of a PRS resource set, the PRS resource set comprising at least one PRS resource, and a second time period between two instances of the PRS resource within the PRS resource set, and
- wherein the first time period between two instances of the PRS resource set is based on a subcarrier spacing;
- and
- transmitting at least one PRS based on the PRS configuration information.
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving positioning reference signal (PRS) configuration information,
- wherein the PRS configuration information defines a first time period between two instances of a PRS resource set, the PRS resource set comprising at least one PRS resource, and a second time period between two instances of the PRS resource within the PRS resource set, and
- wherein the first time period between two instances of the PRS resource set is based on a subcarrier spacing;
- and
- receiving at least one PRS based on the PRS configuration information.
A base station for a wireless communication system, the base station comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- transmit positioning reference signal (PRS) configuration information,
- wherein the PRS configuration information defines a first time period between two instances of a PRS resource set, the PRS resource set comprising at least one PRS resource, and a second time period between two instances of the PRS resource within the PRS resource set, and
- wherein the first time period between two instances of the PRS resource set is based on a subcarrier spacing;
- and
- transmit at least one PRS based on the PRS configuration information.
A user equipment (UE) for a wireless communication system, the UE comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- receive positioning reference signal (PRS) configuration information,
- wherein the PRS configuration information defines a first time period between two instances of a PRS resource set, the PRS resource set comprising at least one PRS resource, and a second time period between two instances of the PRS resource within the PRS resource set, and
- wherein the first time period between two instances of the PRS resource set is based on a subcarrier spacing;
- and
- receive at least one PRS based on the PRS configuration information.
