Method and Apparatus for Transmitting and Obtaining Scheduling Information

A method for obtaining scheduling information, the method comprising:

• learning user equipments (UEs) performing direct communication;
• obtaining invariable or slowly varying control information in the scheduling information transmitted statically or semi-statically by a base station, the scheduling information further comprising quickly varying control information;
• and
• exchanging the quickly varying control information in the scheduling information dynamically or semi-dynamically with other UEs that participate in the direct communication.

An apparatus for transmitting scheduling information, the apparatus comprising:

• a UE determining unit, configured to identify user equipments (UEs) performing direct communication;
• a scheduling information determining unit, configured to determine scheduling information required for data transmission for the UEs performing the direct communication;
• a scheduling information transmitting unit, configured for a base station to transmit invariable or slowly varying control information in the scheduling information to each of the UEs performing the direct communication statically or semi-statically;
• and
• a scheduling information direct exchanging unit, configured for a UE serving as a sender in the UEs performing the direct communication to, if the scheduling information further comprises quickly varying control information, transmit the quickly varying control information in the scheduling information dynamically or semi-dynamically to a UE serving as a receiver in the UEs performing the direct communication.
