METHOD IN A BASE UNIT FOR DETERMINING CANDIDATE RESEARCH SPACES TO THE CONTROL CHANNEL FOR A PARTICULAR REMOTE UNIT, BASE UNIT AND METHOD IN A REMOTE DEVICE FOR THE IDENTIFICATION OF ONE OR MORE CANDIDATE RESEARCH SPACES FOR THE CANDIDATE RESEARCH CHANNEL CONTROL INFORMATION

摘要

base unit and device for candidate control channels and method for them a base unit and a device for identifying candidate search spaces for control channels. according to an aspect 1 the base unit maps the remote unit to a set of candidate control channel elements constituting a candidate search space for the control channel to a control channel for the remote unit. the base unit selects a control channel comprising one or more control channel elements from the set of candidate control channel elements. control information for the remote unit is communicated using the selected control channel. according to another aspect 1 the remote unit uses a signal received from the base unit to identify a candidate control channel search space in which to search for the control signal.
