Abstract: A method, apparatus and computer program product establish at least two redundant protocol data unit sessions to at least one user equipment. The at least two redundant protocol data unit sessions are established based on dual connectivity in a radio access network. The method, apparatus and computer program product collect network status information related to the at least two redundant protocol data unit sessions. The method, apparatus and computer program product configure a set of protocol data unit session switching patterns for the at least two redundant protocol data unit sessions based on the real-time network status information.

Abstract: Various communication systems, such as radio access networks, may benefit from various error correction techniques. For example, certain communication systems may benefit from quality of service driven receiver selective hybrid automatic repeat request for point-to-multipoint communication. A method can include identifying, at a receiver, at least one quality of service threshold. The method can also include identifying, at the receiver, at least one quality of service. The method can further include determining, at the receiver, whether or what kind of feedback is to be used for an erroneously received transport block based on the identified at least one quality of service threshold and the identified at least one quality of service. The method can additionally include communicating, by the receiver, with a transmitter of the erroneously received transport block based on the determination.

Abstract: Methods, apparatuses and computer program products are disclosed for data distribution. A method comprises: sending a message, containing an indication of a target area related to first data to be distributed, from a first distribution unit to a distribution management device; receiving first information comprising at least one target address from the distribution management device in response to sending of the message, wherein the at least one target address is related to one or more second distribution units covering the target area; and sending the first data to the at least one target address when the message does not contain the first data.

Abstract: For a source stream of input data where FEC scheme(s) have been used to create a repair stream, transmitting by a network node packet(s) comprising data of the source stream or the repair stream packaged as at least part of PDU(s). An ARQ or HARQ process is applied to the PDU(s). The network node receives feedback information as part of the process corresponding to the PDU(s), including positive ACK/NACK response for the PDUs. The retransmissions of the negatively acknowledged PDU(s) are controlled when the FEC scheme is known not to be able to compensate for loss(e)s of packet(s) contained in the PDU(s) indicated as being negatively acknowledged. A UE receives packet(s), determines loss(es), and, in response to a determination the FEC scheme is known to be able to recover from the loss(es), sends at least one ACK for any lost packets that correspond to the one or more loss(es).

Abstract: In accordance with some embodiments, a method may include receiving, by a first network entity, at least one user equipment context modification request from a second network entity. The method may further include configuring, by the first network entity, at least one of one or more unicast channels and one or more multicast channels. The method may further include receiving, by the first network entity, multicast data. The method may further include selecting, by the first network entity, at least one of one or more multicast channels and one or more unicast channels to transmit multicast data.

Abstract: According to an aspect, there is provided an access node for a radio access network. The access node comprises means for determining, in response to receiving a plurality of data packets associated with one or more radio bearers for scheduling to terminal devices, an over-the-air transmission mode of each radio bearer. The means are further configured to, in response to determining that the one or more radio bearers comprise one or more first explicit multi-unicast, Xcast, radio bearers using multicast and one or more second radio bearers using unicast, schedule the one or more radio bearers according to a first scheduling mechanism. The first scheduling mechanism prioritizes the one or more first Xcast radio bearers to maximize a system throughput.
