Load-invariant configuration of interference measurement resources

摘要

According to one aspect of this disclosure, the configuration of which Interference Measurement Resources, “IMRs”, a given user equipment, “UE”, should measure for Channel State Information, “CSI”, reporting is made more or less invariant to dynamic traffic variations affecting the set of Coordinated Multi-Point, “CoMP”, transmission points used for serving the UE, or to the use of dynamic blanking for those transmission points. These goals are achieved at least in part by configuring one or more of the transmission points to follow a first rule embodying a negative logic. According to the first rule, the transmission point transmits on a given IMR if it has been deemed as being not likely to transmit data at a time relevant to the IMR, and, conversely, to not transmit the IMR if it has been deemed as being likely to transmit data at a time relevant to the IMR.

主权项

1. A method at a node in a wireless communication network that is configured for Coordinated Multi-Point (CoMP) operation, said method comprising configuring one or more transmission points in a set of CoMP transmission points on a dynamic basis, with respect to one or more defined Interference Measurement Resources (IMRs), including configuring a first transmission point to follow a first rule according to which the first transmission point:
transmits on at least one of the IMRs, if the first transmission point is deemed as being not likely to transmit data at a time relevant to the at least one IMR; and does not transmit on the at least one IMR, if the first transmission point is deemed as being likely to transmit data at a time relevant to the at least one IMR.
