Abstract: A method of carrying out dual connectivity with a secondary access node and an apparatus is provided. A mode of operation of a user equipment is determined in dependence on the presence of bearers mapped to the secondary access node. Operating in a first mode occurs when it is determined that one or more bearers are mapped to a secondary access node. Operation in a second mode occurs when it is determined that no bearers are mapped to the secondary no access node. The second mode comprises limiting a listening time to a downlink channel from the secondary access node with respect to the first mode.

Abstract: A technique is provided to control transmitting, by a mobile station (MS) that uses carrier aggregation, a message including an interoperability test (IOT) indication for one or more uplink-downlink (UL-DL) configuration combinations of time-division-duplex (TDD) radio frames for use by a primary cell and a secondary cell. In one example implementation, an IOT indication may be provided for one or more (or each) uplink-downlink configuration combinations (e.g., one IOT indication per UL-DL configuration combination). In another example implementation, an IOT indication may be provided for one or more sets of uplink-downlink configuration combinations, where each set may include a plurality of UL-DL configuration combinations.

Abstract: Improved mechanisms for wireless cellular access using coverage extension techniques are described. A UE needing to use coverage extension to request access to a prospective serving cell detects cells (other than the prospective serving cell) on its frequency, and then investigates each such cell (for example, by attempting to read its system information block and, if the system information block can be read, determining if the cell supports access using coverage extension. If detected cells do not support coverage extension, the UE does not use coverage extension techniques to request access, but if all detected cells support coverage extension, the UE requests access using coverage extension techniques.

Abstract: A method includes determining at a network node whether paging to be sent from the network node toward an intermediate node for further forwarding to a user equipment will arrive at the user equipment before the user equipment transitions from an idle state to a power save state. The method includes sending or not sending the paging toward the intermediate node based on the determining. Another method includes performing an estimation at a network access node providing wireless network access to a user equipment of how long it will take before a next paging frame or paging occasion occurs for the user equipment, and sending to a network node a value indicative of the estimation. Apparatus, computer programs, and computer program products are also disclosed corresponding to the methods.
