First Claim
Patent Images
1. A method of wireless communication, comprising:
- determining a configuration for a set of component carriers in carrier aggregation, the set of component carriers comprising a time-division duplexing (TDD) secondary component carrier (SCC) and a frequency-division duplexing (FDD) SCC;
identifying a scheduling timing and an uplink hybrid automatic repeat request (HARQ) timing of the FDD SCC based at least in part on a time duration of each frame of the TDD SCC; and
communicating with a node based at least in part on the identified scheduling timing and uplink HARQ timing of the FDD SCC.

Abstract
Methods, systems, and devices for multi-carrier scheduling in wireless communications networks. The described techniques may be employed to minimize hybrid automatic repeat requests (HARQ) delay in a wireless communications network utilizing one or more TDD component carriers and one or more FDD component carriers. Scheduling of TDD uplink (UL) and downlink (DL) may be determined based on an FDD component carrier. A number of HARQ processes may be determined for a TDD component carrier based on DL/UL configuration of the TDD component carrier. Scheduling may include overwriting certain HARQ transfers. The described techniques may apply to any TDD DL/UL configuration.
