Abstract: Various communication systems may benefit from improved network signaling. For example, certain embodiments may benefit from an improved connection between relay nodes and network entities. A method may include receiving at a user equipment part of an integrated access and backhaul node downlink information from a donor node. The downlink information may include F1 application protocol information. The method may also include forwarding the downlink information including the F1 application protocol information from the user equipment part of the integrated access and backhaul node to a radio access network part of the integrated access and backhaul node.

Abstract: A method, apparatus and computer program product are provided to receive, at a user equipment, an indication providing a cell location to which the user equipment, operating in a dual connectivity mode, should transmit a buffer status report for one or more bearers, the cell location being one of a first location, a second location, or a first location and second location and in response to being triggered, causing buffer status report to be transmitted to the location provided in the indication. In some embodiments, the bearer may be a split bearer. In some embodiments, the indication may be provided by RRC signaling, MAC signaling or physical layer signaling.

Abstract: Various communication systems may benefit from an enhanced radio link control status report. A method may include determining a negative acknowledgment sequence number range. The negative acknowledgment sequence number range may include a plurality of consecutive radio link control missing sequence numbers. The method may also include determining at least one of a en negative acknowledgment end sequence number when the plurality of consecutive radio link control missing sequence numbers exceeds the negative acknowledgment sequence number range. In addition, the method may include sending a radio link control status report comprising at least one of a negative acknowledgment sequence number, the negative acknowledgment sequence number range, or the negative acknowledgment end sequence number when the plurality of consecutive radio link control missing sequence numbers exceeds the at least one negative acknowledgment sequence number range.

Abstract: Improved systems and techniques for dual connection to a wireless communications network. In a wireless network comprising one or more macro base stations and secondary base stations, a user device indicates capability to operate and readiness to initiate an alternative multipath transfer control protocol connection. Radio access network procedures provide for communication between a core network, radio access network, and user device to indicate that bearers are being used for, or authorized for use in, an alternative multipath connection and to establish a radio bearer context. In embodiments of the invention, a bearer for alternative multipath connection is established only when a secondary base station becomes available and when a network operator has allowed the use of multipath connection. When a user device indicates that it is ready for multipath connections, core network elements establish bearers, with the alternative connection released when connection to the secondary base station is lost.
