Scheduling and hybrid automatic repeat request (HARQ) timing indication for an uplink-downlink (UL-DL) reconfiguration
First Claim
1. A user equipment (UE) for reconfiguring an uplink-downlink (UL-DL) time-division duplexing (TDD) configuration timing, having computer circuitry configured to:
- decode a physical downlink control channel (PDCCH) for downlink control information (DCI) including a timing indication field (TIF); and
reconfigure a channel timing for a semi-static UL-DL TDD configuration using the TIF, wherein the channel timing is selected from the group consisting of a physical downlink shared channel (PDSCH) hybrid automatic repeat request (HARQ) timing, a physical uplink shared channel (PUSCH) scheduling timing, a PUSCH HARQ timing, and combinations thereof.

Abstract
Technology for reconfiguring an uplink-downlink (UL-DL) time-division duplexing (TDD) configuration timing is disclosed. In an example, a user equipment (UE) for reconfiguring an uplink-downlink (UL-DL) time-division duplexing (TDD) configuration timing can have computer circuitry configured to: Decode a physical downlink control channel (PDCCH) for downlink control information (DCI) including a timing indication field (TIF); and reconfigure a channel timing for a semi-static UL-DL TDD configuration using the TIF. The channel timing can include a physical downlink shared channel (PDSCH) hybrid automatic repeat request (HARQ) timing, a physical uplink shared channel (PUSCH) scheduling timing, or a PUSCH HARQ timing.
