Using a cell as a pathloss or timing reference
First Claim

1. A method comprising:
- sending, by a network node to a mobile device, information 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;
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 whether the cell on the first carrier of the first type is to be used as the reference cell based on determining whether a density of a synchronization signal exceeds a density threshold.

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.

8. 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 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; 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 determine 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. - View Dependent Claims (9, 17, 18, 23, 24, 25, 26, 27)

10. A network node comprising:
-
at least one processor to; send, to a mobile device, information 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; send, to the mobile device, configuration information regarding whether the mobile device is to monitor an enhanced control channel; determine 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 determine whether the cell on the first carrier of the first type is to be used as the reference cell based on determining whether a density of a synchronization signal exceeds a density threshold. - View Dependent Claims (11, 12, 13, 14, 19)
