Method and apparatus for resource aggregation in wireless communications

An apparatus, comprising:

• at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
• receive from a communication device information of a capability of a communications device comprising a predefined maximum number of cells of a plurality of cells that the communication device can support for cell aggregation on a single carrier resource in a communication system, wherein the predefined maximum number of cells defines a maximum number of at least one of physical shared channels and physical control channels that can be received or transmitted by the communication device;
• based on the information, send towards the communication device an indication of channel assignments for the single carrier resource of at least one of physical shared channels and physical control channels specific to the communication device based on the capability information to enable cell aggregation by the communication device using the predefined maximum number of cells;
• and
• control cell aggregation for communications by the communication device with multiple cells of the plurality of cells up to the predefined maximum number of cells comprising simultaneous transmission to and reception from the multiple cells by the communication device using the channels specific to the communication device on the single carrier resource in the communication system.

A method, comprising:

• signalling information of a capability of a communication device comprising a predefined maximum number of cells of a plurality of cells that can be aggregated by a communication device on a single carrier resource in a communication system, wherein the predefined maximum number of cells defines a maximum number of at least one of physical shared channels and physical control channels that can be received or transmitted by the communication device;
• in response to the information, receiving, by the communication device at least an indication of channel assignments for the single carrier resource of at least one of physical shared channels and physical control channels specific to the communication device based on the capability information to enable cell aggregation using the predefined maximum number of cells;
• and
• using the channel assignments, enable cell aggregation for communications by the communication device comprising performing by the communication device simultaneous transmission to the multiple cells and reception from the multiple cells of the plurality of cells using the channels specific to the communication device on the single carrier resource up to said maximum number of cells.
