SIGNALING FOR INDICATING TDD UL-DL SUBFRAME CONFIGURATION IN LTE

摘要

Methods, systems, and devices are described for reconfiguring a user equipment (UE) to operate in a reconfigured TDD UL-DL configuration. An initial uplink- downlink (UL-DL) configuration for TDD communication may be provided for communication between a base station and a UE. One or more subframes may be identified within at least one half of each frame transmitted using the initial UL-DL configuration as flexible subframes. In one example, a reconfiguration message may be received in a first frame indicating that a transmission direction for the at least one flexible subframe of a second frame is to be changed. The reconfiguration message may include, for example, a two-bit configuration indication which indicates that the UE is to reconfigure a transmission direction for one or more flexible subframes in an associated half-subframe of a second frame.
