A method in a network node for handling a transmission between a plurality of Transmission Points, TPs, and User Equipments, UEs, in a wireless network. The network node receives information from each respective UE out of a number of first UEs served by the network node, which information is related to the location of the UE. The network node then identifies a hot spot, based on the information received from the UEs. The hot spot is an area where the load density of UEs is above a first threshold. When a hot spot is defined the network node selects a plurality of TPs dedicated to serve the UEslocated in the hot spot and establishes a coordinated transmission mode from the plurality of dedicated TPs to the UEs located in the hot spot.

Coordinated transmission method for unbalanced load

A method performed by a network node for enabling Interference Alignment, IA, of transmissions to user equipments is provided. The network node receives signal strength values associated with more than one network node for the user equipments, wherein each signal strength value is associated with one network node. Then, the network node schedules a first group of the user equipments on radio transmission resources that are orthogonal to radio transmission resources of at least one other group of the user equipments when an IA gain value for each user equipment in the first group passes a threshold level. The IA gain value is determined by the network node based on the received signal strength values. The network node may then enable IA of transmissions to the scheduled first group of user equipments from at least two network nodes capable of performing IA of transmissions.

Network node and method for enabling interference alignment of transmissions to user equipments

Systems and methods provide for applying a clustering based assignment algorithm (CbAA) in a telecommunication system. A method includes: receiving strength information for transmission points belonging to an associated Coordinated Multi-Point (CoMP)-cell; determining the clustering subsets, wherein the step of determining the clustering subsets includes: applying a k-means algorithm to the strength information to form K clusters; identifying the cluster associated with each UE; associating a cluster to each transmission point in accordance to a pre-defined rule; and selecting the UEs to be serviced; and reporting the clustering formations.
