Abstract
The present invention relates to the field of coordinated multipoint transmission and reception (CoMP) in wireless communication networks, in particular to methods, an apparatus, and a network node for use in performing coordinated data transmissions in a wireless communication network. A method for use in a network node for coordinating data transmission to user equipments in a wireless communication network, wherein the wireless communication network comprising at least two access nodes each access node having one or more antennas and being arranged to perform coordinated data transmissions to user equipments is provided. The method comprising: obtaining signal strength values associated with the one or more antennas of the at least two access nodes for a number of user equipments; arranging the number of user equipments into one or more groups of user equipments and associating each of the one or more groups of user equipments with a sub-set of the one or more antennas of the at least two access nodes based on the obtained signal strength values; and coordinating data transmission performed by the at least two access nodes to each of the one or more groups of user equipments bas…
