Abstract: Flexible carrier aggregation is provided for a radio communications system. A capability is determined to communicate over a radio interface using multiple radio frequency component carriers. Each of the multiple component carriers is configurable with one or more control channels in a first mode of operation and with no control channels in a second mode of operation. Configuration information for one of the multiple radio frequency component carriers is signaled to indicate at least one of the component carriers is configured to operate in a selected one of the first mode of operation and the second mode of operation so that a network radio node and a user equipment radio node can communicate using the selected mode of operation.

Abstract: Techniques are disclosed for identifying carrier-aggregation band combinations that may be supported by a mobile terminal with limited performance. According to one example method, a mobile terminal sends (710) a band capability information element to the network (e.g., to a 3GPP eNB). The band capability information element contains data indicating which band combinations the mobile terminal supports for carrier aggregation. In addition, the mobile terminal sends (720) additional information (e.g., one or more new parameters) associated with at least one specific band combination. In some cases, this new information indicates that a specific band combination has limited support. In these or in other embodiments, the new information contains information about an amount or type of limitation. This latter information may be present on its own, or in combination with the information that more generally indicates that the mobile terminal is capable of only limited support for a specific band combination.

Abstract: Methods may be providing for signal synchronization at a wireless terminal communicating with a radio access network. For example, a command may be received from the radio access network, and the command may be to add a first carrier on a first frequency as a link for communications from the radio access network to the wireless terminal. Responsive to receiving the command to add the first carrier, the first carrier may be synchronized and/or configured using signals of a second carrier on a second frequency different than the first frequency. Related wireless terminals, network nodes, and network node methods are also discussed.

Abstract: A wireless communication node (10) dynamically estimates passive intermodulation (PIM) interference coupled into the node's receive path from the transmission of a composite signal through the node's transmit path. The node (10) then cancels the estimated PIM interference in the receive path. In some embodiments, the node dynamically estimates the PIM interference as a function of the composite signal that models PIM interference generation and coupling in the node (10) according to one or more coefficients (30). The coefficients (30) may be determined by transmitting a test signal (34) during a test stage, when the node (10) is not scheduled to receive any signal. Later, when the composite signal (18) is transmitted, the node (10) uses the coefficients (10) to dynamically estimate and cancel the resulting PIM interference.
