SYSTEMS, METHODS, AND DEVICES TO SUPPORT A FAST TDD CONFIGURATION INDICATION
Systems and methods to support intra-application flow prioritization are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The eNB may be able to quickly change a time division duplexing (TDD) schedule based on the experienced traffic. The eNB may indicate which subframes the UE should monitor for the TDD schedule. The indication may be a bitmap, a code, etc. The bitmap and/or code may be shortened by restricting in which frames and/or subframes the TDD schedule can be transmitted. The UE may monitor the subframes and receive the TDD schedule. The UE may determine a delay before the TDD schedule should be applied. The delay may be determined based on the subframe in which the TDD schedule was received.
