1. A method comprising:
- determining, by a network node, whether a cell on a first carrier of a first type or a cell on a second carrier of a second, different type is to be used as a reference cell, wherein the first carrier and the second carrier are part of a carrier aggregation, and wherein the reference cell is at least one selected from among a pathloss reference cell and a timing reference cell;
sending, by the network node to a mobile device, information indicating whether the cell on the first carrier of the first type or the cell on the second carrier of the second type is to be used as the reference cell;
sending, by the network node to the mobile device, configuration information regarding whether the mobile device is to monitor an enhanced control channel;
determining, by the network node, a delay value associated with modification of the carrier aggregation, the delay value representing a time delay during which the mobile device is unable to receive signaling from the network node responsive to the modification of the carrier aggregation; and
sending, by the network node to the mobile device, the delay value.

Abstract
Information is communicated indicating whether a cell on a first carrier of a first type is to be used as a reference cell, wherein the reference cell is at least one selected from among a pathloss reference cell and a timing reference cell, and wherein the first carrier of the first type is part of a carrier aggregation that further includes at least a second carrier of a second, different type.

4. A method comprising:
-
determining, by a network node, whether a cell on a first carrier of a first type or a cell on a second carrier of a second, different type is to be used as a reference cell, wherein the first carrier and the second carrier are part of a carrier aggregation, and wherein the reference cell is at least one selected from among a pathloss reference cell and a timing reference cell; sending, by the network node to a mobile device, information indicating whether the cell on the first carrier of the first type or the cell on the second carrier of the second type is to be used as the reference cell; sending, by the network node to the mobile device, configuration information regarding whether the mobile device is to monitor an enhanced control channel; determining, by the network node, a delay value associated with modification of the carrier aggregation, the delay value representing a time delay during which the mobile device is unable to receive signaling from the network node responsive to the modification of the carrier aggregation; and determining that the cell on the first carrier of the first type is to be used as the reference cell based on determining that the cell on the first carrier of the first type is not co-located with a cell on the second carrier of the second type, provided that a density of a reference signal or a synchronization signal in the cell on the first carrier exceeds a density threshold, wherein the cell on the first carrier of the first type is co-located with the cell on the second carrier of the second type if an antenna assembly for the cell on the first carrier of the first type is generally at a same location as an antenna assembly for the cell on the second carrier of the second type.

11. A mobile device comprising:
at least one processor to; receive, from a network node, information indicating whether a cell on a first carrier of a first type or a cell on a second carrier of a second, different type is to be used as a reference cell, wherein the reference cell is at least one selected from among a pathloss reference cell and a timing reference cell, and wherein the first carrier and the second carrier are part of a carrier aggregation; determine, based on the information, whether the mobile device is able to use the cell on the first carrier as the reference cell; receive, from the network node, configuration information regarding whether the mobile device is to monitor an enhanced control channel; decode the enhanced control channel in response to the configuration information specifying that the mobile device is to monitor the enhanced control channel; and receive information relating to a Discontinuous Reception (DRX) configuration that is specific to a type of carrier, wherein the information relating to the DRX configuration comprises; information relating to a first DRX configuration for communications with the cell on the first carrier of the first type, and information relating to a second DRX configuration for communications with the cell on the second carrier of the second type. - View Dependent Claims (12, 13, 14, 15, 16)
