According to a first embodiment, a method may include receiving, by a source network entity, a trigger. The method may further include, in response to receiving a trigger, generating, by the source network entity, at least one adaptation layer status report indicating at least one adaptation layer protocol data unit. The method may further include transmitting, by the source network entity, the at least one adaptation layer status report to a target network entity.

Integrated access and backhaul adaptation layer status report

A method for coordinated multipoint transmission includes collecting, in a serving CoMP-MA, channel state information, CSIs, reported by terminals served by eNBs within a cooperating set. The serving CoMP-MA selects dominant interferers as candidate transmitting eNBs for a terminal. CoMP joint transmission is initiated by forwarding, to the candidate transmitting eNBs, PDCP PDUs received from SGW and targeted to the selected terminal, and by setting the status of the terminal to joint transmission. High and low thresholds of PDCP buffers of the serving CoMP-MA are adjusted. As information required for air interface scheduling becomes available, the method includes extracting, in the serving CoMP-MA, radio resource allocations, RLC and MAC headers, references to user plane data, and precoding matrices from protocol entities, and forwarding them to the transmitting eNBs that have acknowledged PDCP PDUs, in order the transmitting CoMP-MA to prepare air interface for the terminal.

Coordinated multipoint joint transmission with relaxed backhaul requirements

The present invention provides a method, apparatus, gateway and a computer program product for reducing overhead on voice traffic within a packet based communication system. The present invention discloses collecting a plurality of packets to be multiplexed in an aggregated frame, measuring a number of received packets within a predetermined time period, and, if the number of received packets reaches a predetermined value, sending the aggregated frame including the collected packets.
