Method and apparatus for sending uplink/downlink scheduling information, and method and apparatus for receiving uplink/downlink scheduling information
First Claim
1. A method for sending uplink scheduling information, comprising:
- determining, in uplink subframes on a second carrier, a first uplink subframe, wherein at a time corresponding to a third downlink subframe for scheduling the first uplink subframe on the second carrier during non-cross-carrier scheduling, a subframe on a first carrier is an uplink subframe; and
sending, on a sixth downlink subframe on the first carrier, uplink scheduling information corresponding to the first uplink subframe on the second carrier to a terminal, wherein time corresponding to the sixth downlink subframe is before time corresponding to the first uplink subframe.

Abstract
The present invention provides a method and an apparatus for sending uplink/downlink scheduling information, and a method and an apparatus for receiving uplink/downlink scheduling information. The method for sending downlink scheduling information includes: determining, in downlink subframes on a second carrier, a first downlink subframe, in which at time corresponding to the first downlink subframe, a subframe on a first carrier is an uplink subframe; and sending, on a fifth downlink subframe on the first carrier, downlink scheduling information corresponding to the first downlink subframe on the second carrier to a terminal, in which time corresponding to the fifth downlink subframe is before the time corresponding to the first downlink subframe. The present invention achieves the purpose of performing uplink and downlink scheduling on a second carrier through a first carrier bearing a PDCCH.

5. A method for receiving uplink scheduling information, comprising:
-
on a sixth downlink subframe that is on a first carrier and that is at time before that of a first uplink subframe, receiving uplink scheduling information which is sent by a base station and is corresponding to the first uplink subframe on a second carrier, wherein at a time corresponding to a third downlink subframe for scheduling the first uplink subframe on the second carrier during non-cross-carrier scheduling, a subframe on the first carrier is an uplink subframe; and sending, on the first uplink subframe on the second carrier, uplink data corresponding to the uplink scheduling information according to the received uplink scheduling information. - View Dependent Claims (6, 7)

8. An apparatus for sending uplink scheduling information, comprising:
-
an uplink subframe determining module, configured to determine, in uplink subframes on a second carrier, a first uplink subframe, wherein at a time corresponding to a third downlink subframe for scheduling the first uplink subframe on the second carrier during non-cross-carrier scheduling, a subframe on the a carrier is an uplink subframe; and an uplink scheduling sending module, configured to send, on a sixth downlink subframe on the first carrier, uplink scheduling information corresponding to the first uplink subframe on the second carrier to a terminal, wherein time corresponding to the sixth downlink subframe is before time corresponding to the first uplink subframe. - View Dependent Claims (9, 10)

11. An apparatus for receiving uplink scheduling information, comprising:
-
an uplink scheduling receiving module, configured to receive, on a sixth downlink subframe that is on a first carrier and that is at time before that of a first uplink subframe, uplink scheduling information which is sent by a base station and is corresponding to the first uplink subframe on a second carrier, wherein at a time corresponding to a third downlink subframe for scheduling the first uplink subframe on the second carrier during non-cross-carrier scheduling, a subframe on the first carrier is an uplink subframe; and an uplink data sending module, configured to send, on the first uplink subframe on the second carrier, uplink data corresponding to the uplink scheduling information according to the received uplink scheduling information. - View Dependent Claims (12, 13)
