Abstract

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a UE in a wireless communication system is provided. The method includes receiving configuration information for a positioning signal, wherein the configuration information includes at least one of time domain information or frequency domain information related to frequency hopping, and wherein the frequency domain information includes at least one of information related to a frequency hopping BWP or information related to a frequency hopping RB; and transmitting the positioning signal based on the configuration information.

Claims (48)

1 . A method performed by a reduced capability (RedCap) user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a location management function (LMF) entity for positioning of a device including the RedCap UE, a first message for a positioning measurement, wherein the first message includes first information indicating to use frequency hopping for a downlink (DL) positioning reference signal (PRS), second information on a duration of a time window for the positioning measurement, and third information on a time offset of the time window for indicating a start of the time window;

performing the positioning measurement using the DL PRS in the time window based on the first information; and

transmitting, to the LMF entity for the positioning of the device, a second message as a response to the first message,

wherein the second message includes a result of the positioning measurement and information indicating whether the positioning measurement is based on the frequency hopping with a single hop or multiple hops, and

wherein, in case that the positioning measurement is based on the frequency hopping with the multiple hops, all of the multiple hops are received during a single measurement gap configured for the RedCap UE.

2 . The method of claim 1 , wherein the LMF entity for the positioning of the device is different from a base station associated with the positioning, and

wherein a bandwidth of all of the multiple hops is greater than a maximum bandwidth of the RedCap UE.

3 . The method of claim 1 , further comprising transmitting, to a base station, a sounding reference signal (SRS) within a time window based on information on a hop bandwidth, information on a number of overlapping resource blocks between hops, and information on a number of hops.

4 . The method of claim 3 , wherein the RedCap UE is configured with the information on the hop bandwidth, the information on the number of the overlapping resource blocks, and the information on the number of the hops.

5 . The method of claim 1 , wherein the positioning measurement is associated with a time difference of arrival (TDOA) positioning.

6 . A reduced capability (RedCap) user equipment (UE) in a wireless communication system, the RedCap UE comprising:

a transceiver; and

a controller coupled with the transceiver and configured to:

receive, from a location management function (LMF) entity for positioning of a device including the RedCap UE, a first message for a positioning measurement, wherein the first message includes first information indicating to use frequency hopping for a downlink (DL) positioning reference signal (PRS), second information on a duration of a time window for the positioning measurement, and third information on a time offset of the time window for indicating a start of the time window,

perform the positioning measurement using the DL PRS in the time window based on the first information, and

transmit, to the LMF entity for the positioning of the device, a second message as a response to the first message,

wherein the second message includes a result of the positioning measurement and information indicating whether the positioning measurement is based on the frequency hopping with a single hop or multiple hops, and

wherein, in case that the positioning measurement is based on the frequency hopping with the multiple hops, all of the multiple hops are received during a single measurement gap configured for the RedCap UE.

7 . The RedCap UE of claim 6 , wherein the LMF entity for the positioning of the device is different from a base station associated with the positioning, and

wherein a bandwidth of all of the multiple hops is greater than a maximum bandwidth of the RedCap UE.

8 . The RedCap UE of claim 6 , wherein the controller is further configured to transmit, to a base station, a sounding reference signal (SRS) within a time window based on information on a hop bandwidth, information on a number of overlapping resource blocks between hops, and information on a number of hops.

9 . The RedCap UE of claim 8 , wherein the RedCap UE is configured with the information on the hop bandwidth, the information on the number of the overlapping resource blocks, and the information on the number of the hops.

10 . The RedCap UE of claim 6 , wherein the positioning measurement is associated with a time difference of arrival (TDOA) positioning.

11 . A method performed by a location management function (LMF) entity in a wireless communication system, the method comprising:

transmitting, to a reduced capability (RedCap) user equipment (UE), a first message for a positioning measurement, wherein the first message includes first information indicating frequency hopping for a downlink (DL) positioning reference signal (PRS), second information on a duration of a time window for the positioning measurement, and third information on a time offset of the time window for indicating a start of the time window, and wherein the positioning measurement using the DL PRS in the time window is based on the first information; and

receiving, from the RedCap UE, a second message as a response to the first message,

wherein the LMF entity is for positioning of a device including the RedCap UE,

wherein the second message includes a result of the positioning measurement and information indicating whether the positioning measurement is based on the frequency hopping with a single hop or multiple hops, and

12 . The method of claim 11 , wherein the LMF entity for the positioning of the device is different from a base station associated with the positioning, and

wherein a bandwidth of all of the multiple hops is greater than a maximum bandwidth of the RedCap UE.

13 . The method of claim 11 , wherein the RedCap UE is configured with information on a hop bandwidth, information on a number of overlapping resource blocks between hops, and information on a number of hops.

14 . The method of claim 13 , wherein the information on the hop bandwidth, the information on the number of the overlapping resource blocks, and the information on the number of the hops are associated with a sounding reference signal (SRS).

15 . The method of claim 11 , wherein the positioning measurement is associated with a time difference of arrival (TDOA) positioning.

16 . A location management function (LMF) entity in a wireless communication system, the LMF entity comprising:

a transceiver; and

a controller coupled with the transceiver and configured to:

transmit, to a reduced capability (RedCap) user equipment (UE), a first message for a positioning measurement, wherein the first message includes first information indicating frequency hopping for a downlink (DL) positioning reference signal (PRS), second information on a duration of a time window for the positioning measurement, and third information on a time offset of the time window for indicating a start of the time window, and wherein the positioning measurement using the DL PRS in the time window is based on the first information, and
