Apparatus and method of performing positioning in new radio
Provided are methods and apparatuses for performing positioning. The method may include receiving SPS configuration information for transmission of a UL PRS from a base station, and transmitting the UL PRS based on the SPS configuration information.
1. A method of a user equipment (UE) for performing positioning, the method comprising:
receiving semi-persistent scheduling (SPS) configuration information for transmission of an uplink positioning reference signal (UL PRS) from a base station, wherein the SPS configuration information includes (i) information on a transmission interval and a transmission periodicity of the UL PRS, and (ii) a bandwidth part (BWP) index indicating a bandwidth part for transmitting the UL PRS among four bandwidth parts configured for the UE, and is received by higher layer signaling;
receiving configuration information on the UL PRS from the base station, wherein the configuration information on the UL PRS includes information on a number of symbols and a comb size for configuring the UL PRS in an uplink slot allocated for the transmission of the UL PRS; and
transmitting the UL PRS based on the SPS configuration information, wherein the UL PRS is configured to be transmitted in all symbols in an uplink slot included in a radio resource for the transmission of the UL PRS.
2. The method according to claim 1 , further comprising: receiving the configuration information on the UL PRS from the base station before the UL PRS is transmitted.
3. A method of a base station for performing positioning, the method comprising:
transmitting semi-persistent scheduling (SPS) configuration information for transmission of an uplink positioning reference signal (UL PRS) to a user equipment (UE), wherein the SPS configuration information includes (i) information on a transmission interval and a transmission periodicity of the UL PRS, and (ii) a bandwidth part (BWP) index indicating a bandwidth part for transmitting the UL PRS among four bandwidth parts configured for the UE, and is received by higher layer signaling;
transmitting configuration information on the UL PRS to the UE, wherein the configuration information on the UL PRS includes information on a number of symbols and a comb size for configuring the UL PRS in an uplink slot allocated for the transmission of the UL PRS; and
receiving the UL PRS based on the SPS configuration information, wherein the UL PRS is configured to be transmitted in all symbols in an uplink slot included in a radio resource for the transmission of the UL PRS.
4. The method according to claim 3 , further comprising: transmitting the configuration information on the UL PRS to the UE before the UL PRS is received.
5. A user equipment (UE) for performing positioning, the UE comprising:
a receiver configured to (a) receive semi-persistent scheduling (SPS) configuration information for transmission of an uplink positioning reference signal (UL PRS) from a base station, and (b) receive configuration information on the UL PRS from the base station, wherein the configuration information on the UL PRS includes information on a number of symbols and a comb size for configuring the UL PRS in an uplink slot allocated for the transmission of the UL PRS, wherein the SPS configuration information includes (i) information on a transmission interval and a transmission periodicity of the UL PRS, and (ii) a bandwidth part (BWP) index indicating a bandwidth part for transmitting the UL PRS among four bandwidth parts configured for the UE, and is received by higher layer signaling; and
a transmitter configured to transmit the UL PRS based on the SPS configuration information, wherein the UL PRS is configured to be transmitted in all symbols in an uplink slot included in a radio resource for the transmission of the UL PRS.
6. The UE according to claim 5 , wherein the receiver receives the configuration information on the UL PRS from the base station before the UL PRS is transmitted.
