RRM reporting method in wireless communication system, and apparatus supporting same
The present invention discloses a method for a terminal reporting radio resource management (RRM) to a base station, and an apparatus supporting the same. More specifically, the present invention discloses a method for a terminal, if a base station transmits signals including an RRM reference signal (RS) by using one or more analogue beams for each symbol, performing RRM measurement in correspondence with the same, and reporting the measured RRM information; and an apparatus supporting the same.
1. A method of performing Radio Resource Management (RRM) reporting by a user equipment in a wireless communication system, the method comprising:
receiving a plurality of RRM reference signals (RSs) from a base station, wherein the plurality of the RRM RSs comprise (i) a synchronization signal (SS), and (ii) a demodulation reference signal for a physical broadcast channel;
performing RRM measurements per beam using the plurality of the RRM RSs, wherein the RRM measurements per beam is performed based on all of the plurality of the RRM RSs related to the same beam; and
reporting the measured RRM information to the base station.
2. The method of claim 1 , wherein the measured RRM information comprises RRM information per beam measured by applying a weight having a predetermined magnitude to a certain RRM RS among the plurality of the RRM RSs.
3. The method of claim 1 , further comprising:
receiving, from the base station, instruction information instructing reporting of an aperiodic RRM measurement result; and
reporting the measured RRM information to the base station through a physical layer signal or a Medium Access Control (MAC) layer signal after a predetermined time from when the instruction information is received.
4. The method of claim 1 , wherein the measured RRM information comprises:
a reference signal received power (RSRP) per beam; and
a reference signal received quality (RSRQ) per beam.
5. The method of claim 1 , wherein the measured RRM information per beam is measured only in one or more symbols in which the plurality of the RRM RSs are transmitted by applying the corresponding beam.
6. A user equipment configured to perform Radio Resource Management (RRM) reporting to a base station in a wireless communication system, the user equipment comprising:
a transmitter;
a receiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
receiving a plurality of RRM reference signals (RSs) from a base station, wherein the plurality of the RRM RSs comprise (i) a synchronization signal (SS) and (ii) a demodulation reference signal for a physical broadcast channel;
performing RRM measurements per beam using the plurality of the RRM RSs, wherein the RRM measurements per beam is performed based on all of the plurality of the RRM RSs related to the same beam; and
report the measured RRM information to the base station.
7. The user equipment of claim 6 , wherein the measured RRM information comprises:
a reference signal received power (RSRP) per beam; and
a reference signal received quality (RSRQ) per beam.
8. The user equipment of claim 6 , wherein the measured RRM information comprises RRM information per beam measured by applying a weight having a predetermined magnitude to a certain RRM RS among the plurality of the RRM RSs.
9. The user equipment of claim 6 , wherein the operations further comprise:
receiving, from the base station, instruction information instructing reporting of an aperiodic RRM measurement result; and
reporting the measured RRM information to the base station through a physical layer signal or a Medium Access Control (MAC) layer signal after a predetermined time from when the instruction information is received.
10. The user equipment of claim 6 , wherein the measured RRM information per beam is measured only in one or more symbols in which the plurality of the RRM RSs are transmitted by applying the corresponding beam.
