MITIGATION OF CONTROL CHANNEL INTERFERENCE
First Claim
1. A primary station comprising:
- a transmitter configured for transmitting control data in a signal to a secondary station according to at least one of the group of;
a subset of a set of resources, a search space, and a spreading code, while a further transmitter of a further primary station is allowed to transmit further control data in a further signal using a further subset of the same set of resources, at a time overlapping a time that the control data is being transmitted, resulting is simultaneous transitions of the control data with the further control data.

Abstract
The present invention relates to a method for operating a network comprising a first primary station and a second primary station, wherein the first primary station serves a first cell including at least one first secondary station communicating with the first primary station and wherein the second primary station serves a second cell including at least one second secondary station communicating with the second primary station, the method comprising the steps of
(a) the first primary station and the second primary station transmitting payloads in a synchronous manner on at least one set of resources,
(b) the first and the second primary stations transmitting control data on the at least one set of resources respectively to the first secondary station and to the second secondary station, wherein the method further comprises (c) at least the first primary station rendering the transmission of control data to the first secondary station orthogonal to the transmission of control data from the second primary station.
