NETWORK NODE, USER NODE AND METHODS FOR POWER BOOSTING DPCCH

摘要

A method in a network node for enhancing a channel estimate based on a Dedicated Physical Control Channel, DPCCH, between a user node and the network node is provided. The DPCCH has a first power. The network node receives (501) the DPCCH. The first power of the DPCCH is boosted with additional power, resulting in a second power. The network node then obtains (502) a channel estimate based on the DPCCH comprising the second power. As soon as said channel estimate is obtained, the network node removes (503) the additional power from the DPCCH based channel estimate.
