Method for transmitting and receiving signal in wireless communication system, and apparatus for supporting same
Various embodiments relate to a next generation wireless communication system for supporting a data transmission rate and the like higher than that of beyond 4th generation (4G) wireless communication systems. According to various embodiments, a method for transmitting and receiving a signal in a wireless communication system, and an apparatus for supporting same may be provided, and other various embodiments may also be provided.
1. A method by a UE (user equipment) comprising:
receiving a system information block (SIB) including assistance data related to positioning,
wherein the assistance data includes resource configuration information related to a PRS (positioning reference signal);
receiving a downlink control channel including downlink control information (DCI),
wherein
the DCI includes information related to a wake-up indication,
wherein the DCI further includes first information including a first bit field of a 1 bit-size indicating whether the UE is configured to acquire a measurement related to the positioning,
wherein, based on a bit value of the wake-up indication being 1 and a bit value of the first bit field being a first value, the UE monitors the PRS for the measurement and starts an on-duration timer, and
wherein, based on the bit value of the wake-up indication being 0 and the bit value of the first bit field being the first value, the UE performs monitoring for the PRS without starting the on-duration timer.
2. The method of claim 1 , wherein,
based on the bit value of the wake-up indication being 1 and the bit value of the first bit field being a second value, the UE performs monitoring for a downlink control channel by starting the on-duration timer without monitoring the PRS.
3. The method of claim 1 , wherein, based on the first information including the first bit field having the first value, the DCI further includes second information indicating whether the UE is configured to report the measurement,
wherein, based on the second information indicating that the UE is configured to report the measurement, the measurement is reported at a resource for reporting of the measurement.
4. The method of claim 3 , wherein, based on the second information indicating that the UE is configured to report the measurement, one or more of an SIB including allocation information about the resource for reporting of the measurement, a paging message, or a message including information related to a random access response (RAR) are received.
5. The method of claim 3 , wherein the second information includes a second bit field of a 1 bit-size,
wherein:
the second bit field having a first value is mapped to the UE being configured to report the measurement; and
the second bit field having a second value is mapped to the UE not being configured to report the measurement.
6. The method of claim 1 , wherein the PRS is received after a time for reception of the DCI.
7. The method of claim 1 , wherein the DCI further includes information indicating, in a bitmap, a positioning method used for the UE to acquire the measurement using the PRS.
8. A UE (user equipment), comprising:
one or more transceivers;
one or more memories; and
one or more processors connected to the one or more transceivers and the one or more memories;
wherein the one or more processors are configured to:
receive a system information block (SIB) including assistance data related to positioning,
wherein the assistance data includes resource configuration information related to a PRS (positioning reference signal);
receive a downlink control channel including downlink control information (DCI),
wherein the DCI includes information related to a wake-up indication,
wherein the DCI further includes first information including a first bit field of a 1 bit-size indicating whether the UE is configured to acquire a measurement related to the positioning,
wherein, based on a bit value of the wake-up indication being 1 and a bit value of the first bit field being a first value, the one or more processors monitor the PRS for the measurement and start an on-duration timer, and
wherein, based on the bit value of the wake-up indication being 0 and the bit value of the first bit field being the first value, the one or more processors perform monitoring for the PRS without starting the on-duration timer.
9. The UE of claim 8 , wherein,
based on the bit value of the wake-up indication being 1 and the bit value of the first bit field being a second value, the one or more processors perform monitoring for a downlink control channel by starting the on-duration timer without monitoring the PRS.
10. The UE of claim 8 , wherein, based on the first information including the first bit field having the first value, the DCI further includes second information indicating whether the UE is configured to report the measurement,
wherein, based on the second information indicating that the UE is configured to report the measurement, the measurement is reported at a resource for reporting of the measurement.
11. The UE of claim 8 , wherein the UE is configured to communicate with one or more of a mobile terminal, a network, and an autonomous vehicle other than a vehicle containing the UE.
