Power-efficient measurement reporting for multi/dual connectivity in cellular communication networks

An apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to perform:

• select, by a user equipment, based on an uplink transmission power to a first node and an uplink transmission power to at least one second node, a Radio Resource Control, RRC, connection for transmitting measurement reports, wherein the user equipment compares the uplink transmission power of the first node to the uplink transmission power of the at least one second node and selects the RRC connection for transmitting to the at least one second node wherein the uplink transmission power for the first node is greater than the uplink transmission power of the at least one second node plus a hysteresis threshold, and wherein the user equipment starts a timer such that measurement reports are sent to the at least one second node at least until expiration of the timer, wherein the selecting further includes the user equipment:
• calculating the uplink transmission power to the first node;
• calculating the uplink transmission power to the at least one second node;
• and
• wherein the selecting further comprises comparing the calculated uplink transmission power to the first node and the calculated uplink transmission power to the at least one second node;
• and
• transmit, by the user equipment, using the selected RRC connection, a measurement report associated with a transmission of the first node and/or a measurement report associated with a transmission of the at least one second node.
