Claim Text:
1. A method in a user equipment device for estimating a downlink channel upon receiving an enhanced control channel (eCCH) from a network node in a telecommunications system, wherein the eCCH is distributed over a plurality of resource block pairs, wherein each of the plurality of resource block pairs comprises a plurality of resources, and wherein each of the plurality of resources is associated with a respective antenna port, the method comprising: identifying an antenna port being associated with multiple ones of the plurality of resources, wherein the multiple ones of the plurality of resources associated with the antenna port are present in different ones of the plurality of resource block pairs over which the eCCH is distributed, wherein the identifying is based on how the eCCH is mapped to the plurality of resource block pairs; and estimating the downlink channel for the eCCH based on the identified antenna port in the multiple ones of the plurality of resources in the plurality of resource block pairs; wherein the multiple ones of the plurality of resources in the different ones of the plurality of resource block pairs reflect a same downlink channel for the eCCH based on a mapping condition, the mapping condition being based on frequency proximity between the plurality of resource block pairs.
