Devices for reconfiguring a subframe allocation
An evolved Node B (eNB) for reconfiguring a subframe allocation is described. The eNB includes a processor and instructions stored in memory that is in electronic communication with the processor. The eNB determines whether to adjust a subframe allocation. If it is determined to adjust the subframe allocation, then the eNB determines whether to adjust the subframe allocation with a radio resource control (RRC) reconfiguration or a physical (PHY) layer reconfiguration. The eNB also adjusts the subframe allocation for the PHY layer reconfiguration. The eNB further adjusts the subframe allocation according to a standard configuration for the RRC reconfiguration.
1. A User Equipment (UE) for reconfiguring a subframe allocation, comprising:
a processor;
memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to:
receive physical (PHY) layer signaling in a downlink subframe;
determine whether an error is detected;
determine a target downlink subframe corresponding to the physical layer signaling; and
convert the target downlink subframe to a special subframe type 2 based on the PHY layer signaling if no error is detected, wherein the special subframe type 2 comprises at least an uplink pilot time slot (UpPTS).
2. The UE of claim 1 , wherein determining whether an error is detected is based on a set of downlink subframes that are allowed to be converted to special subframe type 2 subframes among seven TDD UUDL configurations.
3. The UE of claim 1 , wherein determining whether an error is detected is based on a set of allowed transitional states between TDD UL/DL configurations.
4. A method for reconfiguring a subframe allocation on a User Equipment (UE), comprising:
receiving physical (PHY) layer signaling in a downlink subframe;
determining whether an error is detected;
determining a target downlink subframe corresponding to the physical layer signaling; and
converting the target downlink subframe to a special subframe type 2 based on the PHY layer signaling if no error is detected, wherein the special subframe type 2 comprises at least an uplink pilot time slot (UpPTS).
5. The method of claim 4 , wherein determining whether an error is detected is based on a set of downlink subframes that are allowed to be converted to special subframe type 2 subframes among seven TDD UL/DL configurations.
6. The method of claim 4 , wherein determining whether an error is detected is based on a set of allowed transitional states between TDD UL/DL configurations.
