Abstract
A method is disclosed for operating a communication device that is configured with a plurality of cells to provide carrier aggregation for communication with a wireless communication network. The method includes receiving an instruction to activate a cell of the plurality of cells that are configured for the communication device, and starting a discontinuous reception (DRX) inactivity timer associated with the cell of the plurality of cells responsive to receiving the instruction to active the cell of the plurality of cells. Corresponding communication devices are disclosed. Also, related radio access network nodes and methods are disclosed.
Claims19
A method of operating a communication device, wherein the communication device is configured with a plurality of cells to provide carrier aggregation for communication with a wireless communication network, the method comprising:
- receiving an instruction to activate a cell of the plurality of cells that are configured for the communication device;
- and
- starting a discontinuous reception (DRX) inactivity timer associated with the cell of the plurality of cells responsive to receiving the instruction to activate the cell of the plurality of cells, wherein:
- a first DRX inactivity timer is associated with a first cell of the plurality of cells,
- the cell of the plurality of cells is a second cell,
- the DRX inactivity timer associated with the cell of the plurality of cells is a second DRX inactivity timer associated with the second cell, and
- the instruction to activate the second cell is received over the first cell.
A method of operating a node of a wireless communication network in communication with a communication device, wherein the communication device is configured with a plurality of cells to provide carrier aggregation, wherein a first cell of the plurality of cells is associated with a first discontinuous reception (DRX) inactivity timer having a first inactivity timer duration, and wherein a second cell of the plurality of cells is associated with a second DRX inactivity timer having a second inactivity timer duration different from the first inactivity timer duration, the method comprising:
- transmitting an instruction to the communication device to activate the second cell that is associated with the second DRX inactivity timer, where the instruction is transmitted over the first cell associated with the first DRX inactivity timer;
- and
- transmitting scheduling information relating to the second cell for the communication device during a period defined by the second inactivity timer duration following the instruction.
