Method and apparatus for optimized OFDMA subcarrier allocation

A method of OFDMA subcarrier allocation for stations in a wireless network includes determining a total downlink buffered traffic load for downlink traffic from a gateway device to the stations, and receiving a total uplink buffered traffic load for uplink traffic from the stations to the gateway device. The method further includes determining a first ratio of total downlink buffered traffic load for each station in relation to total downlink buffered traffic load for all stations, determining a second ratio of total uplink buffered traffic load for each station in relation to total uplink buffered traffic load for all stations, performing OFDMA subcarrier allocation for the downlink traffic by assigning available channel bandwidth proportional to the first ratio for each station, and performing OFDMA subcarrier allocation for the uplink traffic by assigning available channel bandwidth proportional to the second ratio for each station.

Embodiments herein relate to, for example, a method performed by a first radio network node (12) for handling communication in a wireless communications network. The first radio network node receives from a second radio network node (15), an indication indicating whether handover or cell reselection to the second radio network node is confirmed or not, wherein the indication indicates whether a migrating node and/or one or more other nodes, directly and indirectly served by the migrating node, are accepted or cancelled for handover or cell reselection to the second radio network node (15). The first radio network node further determines to cancel handover or cell reselection of a subset of the one or more other nodes based the received indication.

Handling Communication

Embodiments herein relate to, for example, a method performed by a first radio network node (12) for handling communication in a wireless communications network. The first radio network node (12) transmits a message related to handover or cell reselection of a migrating node to a second radio network node (15), wherein the message comprises data associated with the migrating node and data related to one or more other nodes directly and indirectly served by the migrating node.

METHODS, SYSTEMS AND COMPUTER PROGRAMS FOR IMPROVING DATA THROUGHPUT VIA BACKHAUL SHARING

Improvement of data throughput via backhaul sharing is accomplished by accessing a cell site servicing data transmission at a first data rate and a connected backhaul network having a backhaul data rate. A determination of whether the first data rate exceeds the backhaul data rate is made and an excess data rate is determined. When the first data rate exceeds the backhaul data rate a neighboring cell site having a second backhaul networks is accessed. A determination is made of how much additional capacity the second backhaul network can handle. When the neighboring cell site can handle the excess data rate backhaul sharing using beamforming is initiated.

Information transmission method and apparatus

This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
