A method for distributing the traffic load in a multi radio access technology heterogeneous network, the network including macrocells operating in a first sub-6 GHz band, and minicells that can operate in the sub-6 GHz band and in a millimeter band. The distribution of the traffic is carried out with an association strategy that calls upon, on the first hand, a first bias (Q.sub.T) in order to favour the association with the base stations of the minicells/macrocells and a second bias (Q.sub.R) in order to favour the use of the millimeter/sub-6 GHz band when the terminal is associated with a base station SBS of a minicell.

Provided are apparatuses and methods of managing a load of a base station node in fifth generation (5G) networks. The method of a master base station for managing a load of a secondary base station may include establishing dual connectivity with the secondary base station, receiving a secondary base station status indication message from the secondary base station through an X2 interface, and determining whether to apply an action for reducing a load of the secondary base station based on a value of a secondary base station load information parameter included in the secondary base station status indication message.

The present invention relates to a method and an apparatus for applying wireless resources in order to control inter-cell interference in a heterogeneous network system. The method for applying wireless resources provided by the present invention generates an almost blank subframe (ABS) pattern on the basis of the type of data transmitted from at least one of a first base station and a second base station, applies a non-ABS or an ABS to wireless resources of the first base station according to the generated ABS pattern, and performs data communication by using the wireless resources to which the ABS has been applied.

A mobile communications network, method, and base station arranged to request and analyze measurement information from one or more infrastructure units including one or more relay nodes and one or more mobile communication terminals. The base station then sets forwarding rules in a relay node according to the measurement information reported so that the relay mode may forward any data received as soon as possible, or aggregate data over a period of time and only forward it once predetermined conditions have been met.

A system for channel access in Long Term Evolution (LTE) License-Assisted Access (LAA) is disclosed. The system includes a controller and a plurality of radio points. A level one radio point transmits a first reservation signal in response to a first backoff counter reaching zero. The first reservation signal indicates that the level one radio point will begin a first transmission of a first duration starting in a next subframe. A candidate level two radio point receives the first reservation signal and determines whether the candidate level two radio point received the first reservation signal with a signal to interference noise ratio (SINR) that exceeds a reservation detection threshold for the candidate level two radio point.

The present invention relates to the field of communications technologies, and in particular, to an RLC data packet offloading method and a base station, so as to solve a problem that performance of UE in a CA scenario of a non-ideal backhaul HetNet is affected due to a relatively long transmission delay between a macro eNodeB and a micro eNodeB. In embodiments of the present invention, a micro eNodeB may request a required RLC data packet before scheduling is performed; therefore, a macro eNodeB can send, to the micro eNodeB in advance, the RLC data packet required by the micro eNodeB, which reduces a transmission delay between the macro eNodeB and the micro eNodeB as much as possible, and improves receiving performance of UE.

The present invention relates to an interference control method and an apparatus therefor in a heterogeneous system. To this end, the present invention relates to an interference control method for an almost blank subframe (ABS) ratio determination apparatus in a wireless communication system in which a cell range expansion (CRE) area is defined, comprising the steps of: receiving information about data load within a cell from one or more first cells, and one or more second cells; determining an ABS ratio on the basis of the wireless resource requirements of a CRE terminal with respect to the wireless resource requirements of all cells that are obtained from the data load information; and transmitting the determined ABS ratio to one of the first cells and the second cells.

The application provides a service data splitting method and apparatus. A SeNB receives distributed service data from an MeNB based on a first expected volume of distributed data, and buffers the distributed service data. The SeNB determines a data volume change status of the distributed service data when a preset period expires, where the data volume change status includes a buffered-data volume reduced state, a buffered-data volume accumulated state, and a received-data volume insufficient state. The SeNB adjusts the first expected volume of distributed data based on the data volume change status to obtain a second expected volume of distributed data. and the SeNB sends the second expected volume of distributed data to the MeNB, so that the MeNB performs splitting based on the second expected volume of distributed data.

A load distribution method and apparatus of a base station are disclosed. The method includes measuring load information associated with the BS; transmitting the measured load information to at least one adjacent BS; receiving load information from the at least one adjacent BS; generating a first cluster including the BS and the at least one adjacent BS; and executing a load distribution operation with respect to the first cluster, wherein at least one BS included in the first cluster is included in a second cluster.
