User equipment and network node for configuring measurements of cells and beams in a wireless communication system
Configuration of measurement requirements on cells and beams in NR is made more efficient by, in a user equipment, UE, receiving, information from a network node, which information indicates: a first number K of beams to be measured by the UE, and a second number L of cells in which the UE is required to measure the first number K of beams. The UE then carries out measurements using the received information; and performs at least one operational task based on a result of the measurements.
1. A method implemented in a user equipment, UE, the method comprising:

carrying out measurements using the received information; and
performing at least one operational task based on a result of the measurements,
wherein the first number (K) specifies either:
a total number of beams to be measured in all the second number (L) of cells, or
a respective number of beams to be measured in each cell of the second number (L) of cells.

a total number of beams to be measured in all the second number (L) of cells, or
a respective number of beams to be measured in each cell of the second number (L) of cells.
4. The UE according to claim 3 , wherein the radio interface and the processing circuitry are further configured to:
transmit a message to the network node, which message reflects a capability of the UE to carry out measurements in agreement with the received information, and which message is transmitted before the UE receives the information from the network node.
5. A method implemented in a network node, the method comprising:
determining a first number (K) of beams to be measured by a user equipment, UE, and a second number (L) of cells in which the UE shall measure the first number (K) of beams; and
transmitting information to the UE, which information indicates the first and second numbers (K; L)
wherein the first number (K) specifies either:
a total number of beams to be measured in all the second number (L) of cells, or
a respective number of beams to be measured in each cell of the second number (L) of cells.
6. The method according to claim 5 , further comprising:
receiving a message from the UE, which message reflects a capability of the UE to carry out measurements in agreement with the transmitted information, and which message is received before transmitting the information to the UE.
7. A network node configured to communicate with a user equipment, UE, the network node comprising a radio interface and processing circuitry configured to:
determine a first number (K) of beams to be measured by the UE and a second number (L) of cells in which the UE shall measure the first number (K) of beams; and
transmit information to the UE, which information indicates the first and second numbers (K; L),
wherein the first number (K) specifies either:
a total number of beams to be measured in all the second number (L) of cells, or
a respective number of beams to be measured in each cell of the second number (L) of cells.
8. The network node according to claim 7 , wherein the radio interface and processing circuitry are further configured to:
receive a message from the UE, which message reflects a capability of the UE to carry out measurements in agreement with the transmitted information, and which message is received before transmitting the information to the UE.
9. A computer program comprising computer code which, when run on processing circuitry of a user equipment, UE, causes the UE to be configured to:
receive, from a network node, information indicating:
a first number (K) of beams to be measured by the UE, and
a second number (L) of cells in which the UE is required to measure the first number (K) of beams;
carry out measurements using the received information; and
perform at least one operational task based on a result of the measurements,
wherein the first number (K) specifies either:
a total number of beams to be measured in all the second number (L) of cells, or
a respective number of beams to be measured in each cell of the second number (L) of cells.
