Method of supplying presence information by presence server in IMS-based DASH service, and user equipment (UE) receiving presence information via presence server

摘要

Technology for dynamically reconfiguring an uplink-downlink (UL-DL) time-division duplexing (TDD) configuration is disclosed. In an example, a user equipment (UE) can have computer circuitry configured to: Receive a UL-DL reconfiguration indicator from a node to dynamically reconfigure a flexible subframe (FlexSF) to a different UL-DL transmission direction from a semi-static UL-DL configuration; apply a DL channel timing based on a DL favored UL-DL configuration; and apply a UL channel timing based on a UL favored UL-DL configuration. The FlexSF can be capable of changing an UL-DL transmission direction. The DL favored UL-DL configuration can include more DL subframes than a semi-static UL-DL TDD configuration for the UE, and the UL favored UL-DL configuration includes more UL subframes than a semi-static UL-DL TDD configuration for the UE.
