First Claim
Patent Images
1. A method for wireless communications, comprising:
- generating control information for scheduling transmissions in one or more subframes;
transmitting the control information to a user equipment in a downlink control channel with at least one field, wherein different values of the at least one field indicate different combinations of one or more subframes and one or more component carriers to which the control information is to be applied.

Abstract
Techniques for cross-subframe and cross-carrier scheduling of uplink and downlink transmissions in a multi-carrier wireless communication system are disclosed. A base station can include cross-subframe, carrier indication (xSF/CIF) information in a PDCCH message to signal to a user equipment (UE) which subframes and/or component carriers pertain to control information carried therein. The UE may utilize the xSF/CIF information to determine to which subframes and/or component carriers the control information is to be applied.
