Abstract
An operation method of a first device 100 in wireless communication system is proposed. The method may comprise: generating an SL PRS for positioning for the first device 100; spreading the first SL PRS into a plurality of first sub SL PRSs; transmitting the plurality of first sub SL PRSs based on a plurality of SL resources different from each other; and performing the positioning for the first device 100, based on the plurality of first sub SL PRSs.
Claims12
A method performed by a first device, the method comprising:
- obtaining information related to a resource pool,
- wherein the information related to the resource pool includes information related to a sidelink (SL) positioning reference signal (PRS);
- generating a first SL PRS for positioning for a first device;
- spreading the first SL PRS into a second sub SL PRS and a third sub SL PRS;
- transmitting the second sub SL PRS and the third sub SL PRS based on a plurality of SL resources different from each other;
- and
- performing the positioning for the first device, based on the second sub SL PRS and the third sub SL PRS,
- wherein based on the first SL PRS being spread into 2 sub SL PRSs
- the second sub SL PRS is transmitted in a time resource region of odd index or a frequency resource region of odd index;
- and
- the third sub SL PRS is transmitted in a time resource region of even index or a frequency resource region of even index.
8 more elements
A first device comprising:
- one or more processors;
- one or more transceivers;
- and
- one or more memories connected to the one or more processors and storing instructions,
- wherein the instructions, based on being executed by the one or more instructions, cause the first device to:
- obtain information related to a resource pool,
- wherein the information related to the resource pool includes information related to a sidelink (SL) positioning reference signal (PRS);
- generate a first SL PRS for positioning for the first device;
- spread the first SL PRS into a second sub SL PRS and a third sub SL PRS;
- transmit the second sub SL PRS and the third sub SL PRS based on a plurality of SL resources different from each other;
- and
- perform the positioning for the first device, based on the second sub SL PRS and the third sub SL PRS,
- wherein based on the first SL PRS being spread into 2 sub SL PRSs
- the second sub SL PRS is transmitted in a time resource region of odd index or a frequency resource region of odd index;
- and
- the third sub SL PRS is transmitted in a time resource region of even index or a frequency resource region of even index.
13 more elements
A processing device adapted to control a first device, the processing device comprising:
- one or more processors;
- and
- one or more memories connected to the one or more processors and storing instructions,
- wherein the instructions, based on being executed by the one or more processors, cause the first device to:
- obtain information related to a resource pool,
- wherein the information related to the resource pool includes information related to a sidelink (SL) positioning reference signal (PRS);
- generate a first SL PRS for positioning for the first UE;
- spread the first SL PRS into a second sub SL PRS and a third sub SL PRS;
- transmit the second sub SL PRS and the third sub SL PRS based on a plurality of SL resources different from each other;
- and
- perform the positioning for the first UE, based on the second sub SL PRS and the third sub SL PRS,
- wherein based on the first SL PRS being spread into 2 sub SL PRSs
- the second sub SL PRS is transmitted in a time resource region of odd index or a frequency resource region of odd index;
- and
- the third sub SL PRS is transmitted in a time resource region of even index or a frequency resource region of even index.
