METHOD FOR TRANSMITTING DOWNLINK CONTROL INFORMATION, METHOD FOR BLIND DETECTION, BASE STATION AND TERMINAL EQUIPMENT

摘要

A method for transmitting Downlink Control Information (DCI), a method for blind detection, a base station and terminal equipment, including: a base station generates a DCI, such that a bit length of the DCI of terminal equipment configured with a carrier segment is equal to that of a DCI of the same format of terminal equipment not configured with a carrier segment; the base station transmits the DCI for the terminal equipment configured with the carrier segment in a common search region of a control channel. Or the base station transmits user-specific DCI in a user-specific search region for the terminal equipment configured with the carrier segment, while does not transmit corresponding user-specific DCI in the common search region of the control channel. The bit length of the common search region will not be increased, avoiding the increase of the number of blind detections at the terminal equipment.

1. A base station, when a bit length of a Resource Assignment (RA) domain in a Downlink Control Information (DCI) of terminal equipment configured with a carrier segment is unequal to that of a RA domain in a DCI of terminal equipment not configured with a carrier segment, the base station comprising:
a first information generating unit configured to generate a DCI for terminal equipment configured with a carrier segment, such that a bit length of the DCI of the terminal equipment configured with the carrier segment is equal to that of a DCI of the same format of terminal equipment not configured with a carrier segment; and a first information transmitting unit configured to transmit the DCI for the terminal equipment configured with the carrier segment in a common search region of a control channel, the DCI being common DCI or user-specific DCI.
