METHOD FOR RECEIVING DOWNLINK CONTROL SIGNAL, USER EQUIPMENT, METHOD FOR TRANSMITTING DOWNLINK CONTROL SIGNAL AND BASE STATION

摘要

In the event where a channel strength between UE and eNB is weakened, the eNB of the present invention may configure downlink control information into the format in which at least one of fields of pre-defined existing format is deleted, the length of a relevant field is shortened to be shorter than a pre-defined length of the relevant field, or an error correcting code is added by the amount of the length deleted or reduced. UE decodes a downlink signal according to the modified format to acquire downlink control information of its own.
