US 10,873,369 B2 · Coordinated multi-point (CoMP) transmission from a CoMP cluster

Abstract

A coordinated multipoint (CoMP) controller coordinates transmission from a CoMP cluster to a wireless communication device. The CoMP controller determines, from among multiple different coordination hypotheses for how to coordinate transmissions from the CoMP cluster to the wireless communication device, a coordination hypothesis to apply. The CoMP controller applies the determined coordination hypothesis to transmissions from the CoMP cluster on channel state information (CSI) radio resources on which the wireless communication device is to perform CSI measurements. Notably, though, the CoMP controller defers applying the determined coordination hypothesis to transmissions from the CoMP cluster on user data radio resources, until after the determined coordination hypothesis is applied to the transmissions on the CSI radio resources.
