US 11,601,880 B2 · Power management for a user equipment in a multi-radio connectivity mode or carrier aggregation mode

Abstract

A UE may, responsive to detecting a power-related condition, send a message to induce the master node to release the secondary node. Such a message can include a message reporting a radio link failure of the secondary node, or, if a channel quality indicator is configured for at least some of the secondary cells of the secondary node, reporting a low CQI value so that the network can cease scheduling on such cells. Alternatively, in a carrier aggregation (CA) mode, with the UE connected to a single node comprising a primary cell and one or more secondary cells, the UE may not control which and how many secondary cells with which it communicates. In such a scenario, if such secondary cells are configured for channel quality indicator reporting, the UE may report a low CQI value so that the node will cease scheduling data on such cells.

Dependent claims

A method for reducing power consumption by a user equipment (UE), the method comprising:

entering, by the UE, a multi-radio connectivity mode in which the UE is able to receive user data from a master node or a secondary node, wherein the master node controls a connection of the UE to the secondary node in the multi-radio connectivity mode and the secondary node comprises one or more secondary cells;
determining, by the UE, whether each of the one or more secondary cells configured on the secondary node is a channel quality indicator (CQI)-configured secondary cell for which CQI is configured;
detecting, by the UE, a power-related condition of the UE;
and
sending, responsive at least in part to detecting the power-related condition of the UE,
from the UE to the master node, a message to indicate to the master node to release the connection of the UE to the secondary node, wherein sending the message to indicate to the master node to release the connection of the UE to the secondary node is further based on a determination that none of the one or more secondary cells configured on the secondary node are CQI-configured secondary cells, or
from the UE to the secondary node, a message to indicate to the secondary node to stop scheduling on at least one of the secondary cells configured on the secondary node.
