Abstract

A method in a user equipment device for estimating a channel upon receiving an enhanced control channel (eCCH) from a network node in a telecommunications system includes distributing the eCCH over multiple resource pairs, where each of the multiple resource block pairs includes a number of resources. Each of the resources is associated with a respective antenna port. The user equipment device identifies an antenna port that is associated with multiple ones of the resources. The multiple ones of the resources are present in different resource block pairs of the multiple resource block pairs over which the eCCH is distributed. Identifying the antenna port is based on how the eCCH is mapped to the multiple resource block pairs. The user equipment device estimates the downlink channel for the eCCH based on the identified antenna port in the multiple ones of the resources in the multiple resource block pairs.
