Abstract

The present disclosure relates to a fifth generation (5G) or pre-5G communication system to be provided to support a higher data transmission rate since fourth generation (4G) communication systems like long term evolution (LTE). A method for generating cell measurement information is provided. The method includes receiving measurement configuration information associated with a beam reference signal that is a beamformed reference signal, receiving beam reference signals per a plurality of beam pairs consisting of a base station's (5G-NB's) beam and a user equipment's (UE's) beam, generating beam measurement information based on the beam reference signals received per the plurality of beam pairs, and generating cell measurement information on a cell based on the beam measurement information.

First claim

What is claimed is:

1. A method of a user equipment (UE), the method comprising:
receiving, from a base station, measurement configuration information;
receiving, from the base station, reference signals, each of the reference signals corresponding to each of beams;
obtaining beam measurement results for each of the beams by measuring each of the reference signals corresponding to each of the beams based on the measurement configuration information;
obtaining a value associated with a cell that is used to determine cell level mobility based on at least one of the beam measurement results; and
transmitting a measurement report based on the value associated with the cell,
wherein the value associated with the cell is determined based on an average of highest beam measurement results above a threshold value,
wherein the value associated with the cell is filtered based on a previous filtered beam measurement result,
wherein the measurement configuration information includes a filtering coefficient that is used to filter the value associated with the cell, and
wherein the measurement configuration information is received via radio resource control (RRC) signaling.

2. The method of claim 1 , further comprising:
transmitting the measurement report in case that a reporting condition is satisfied.

3. The method of claim 1 , wherein a number of the beams corresponding to the highest beam measurement results above the threshold value does not exceed a value configured by RRC signaling.

4. A method of a base station, the method comprising:
transmitting, to a user equipment (UE), measurement configuration information;
transmitting, to the UE, reference signals, each of the reference signals corresponding to each of beams; and
receiving, from the UE, a measurement report based on a value associated with a cell that is used to determine cell level mobility, the value associated with the cell being determined based on at least one of beam measurement results for each of the beams,
wherein the value associated with the cell is determined based on an average of highest beam measurement results above a threshold value,
wherein the value associated with the cell is filtered based on a previous filtered beam measurement result,
wherein the measurement configuration information includes a filtering coefficient which is used to filter the value associated with the cell, and
wherein the measurement configuration information is transmitted via radio resource control (RRC) signaling.

5. The method of claim 4 , wherein the receiving the measurement report comprises receiving the measurement report in case that a reporting condition is satisfied.

6. The method of claim 4 , wherein a number of the beams corresponding to the highest beam measurement results above the threshold value does not exceed a value configured by RRC signaling.

7. A user equipment (UE) comprising:
a transceiver; and
at least one processor configured to:
receive, via the transceiver from a base station, measurement configuration information,
receive, via the transceiver from the base station, reference signals, each of the reference signals corresponding to each of beams,
obtain beam measurement results for each of the beams by measuring each of the reference signals corresponding to each of the beams based on the measurement configuration information,
obtain a value associated with a cell that is used to determine cell level mobility based on at least one of the beam measurement results, and
transmit a measurement report based on the value associated with the cell,
wherein the value associated with the cell is determined based on an average of highest beam measurement results above a threshold value,
wherein the value associated with the cell is filtered based on a previous filtered beam measurement result,
wherein the measurement configuration information includes a filtering coefficient that is used to filter the value associated with the cell, and
wherein the measurement configuration information is received via radio resource control (RRC) signaling.

8. The UE of claim 7 ,
wherein a number of the beams corresponding to the highest beam measurement results above the threshold value does not exceed a value configured by
RRC signaling.

9. The UE of claim 7 , wherein the at least one processor is configured to transmit the measurement report in case that a reporting condition is satisfied.

10. A base station comprising:
a transceiver; and
at least one processor configured to:
transmit, to a user equipment (UE), measurement configuration information, transmit, to the UE, reference signals, each of the reference signals corresponding to each of beams, and
receive, from the UE, a measurement report based on a value associated with a cell that is used to determine cell level mobility, the value associated with the cell being determined based on at least one of beam measurement results for each of the beams,
wherein the value associated with the cell is determined based on an average of highest beam measurement results above a threshold value,
wherein the value associated with the cell is filtered based on a previous filtered beam measurement result,
