Abstract: Various methods are provided for triggering a power headroom report. One example method may include storing a first pathloss value and a second pathloss value for a first entity and a first pathloss value and a second pathloss value for a second entity, for each of the first entity and second entity, determining whether first pathloss value or second pathloss value has changed more than a corresponding threshold value, determining whether the UE has UL resources for a new transmission, and in an instance where, for at least one of the first entity or second entity, the first pathloss value or second pathloss value has changed (e.g., increased or decreased) more than the corresponding threshold value, triggering a PHR. A corresponding apparatus and computer program product are also provided.

Abstract: Methods and apparatus, including computer program products, are provided for providing a preference to a user equipment to indicate how the user equipment should respond to a paging message and the like. The method may include receiving, at a user equipment, an indication representative of whether the user equipment should respond to a base station or respond to an access point; and accessing, based on the received indication, at least one of the base station or the access point to enable offloading to the access point. Related apparatus, systems, methods, and articles are also described.

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 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: 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: 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.
