PROVIDING CONTROL AND SIGNALLING CHANNEL Russian patent published in 2014 - IPC H04L5/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication. The invention discloses a communication device and a base unit and methods thereof for determining control information. The communication device receives a control channel message associated with the communication device in a control region at the first carrier from a base unit. The communication device also determines a set of resources in a search region within the control region, attempts to decode the set of resources in the search region for the control channel message and determines control information from the decoded control channel message. The base unit generates the control channel message containing control information associated with the communication device, determines the set of resources in the search region within the control region, selects a subset of resources within the determined set of resources for transmitting the control channel message and transmits the control channel message on the selected resources in the control region at the first carrier.

EFFECT: fewer blind decoding instances and simpler user equipment.
