FLEXIBLE SPECIAL SUBFRAME CONFIGURATION FOR TDD IN LTE
First Claim
1. A method of wireless communication, comprising:
- determining, by a user equipment (UE), a first configuration for a first special subframe in a radio transmission in a frame; and
determining, by the UE, a second configuration for a second subframe in the frame, wherein the first configuration is different than the second configuration and the second configuration comprises at least a guard period (GP).

Abstract
Dynamically changing uplink-downlink configurations in adjacent cells in a TDD networks introduces interference to special subframes between downlink and uplink transmissions. Adaptation is disclosed of different special subframe configurations for certain subframes based on different communication environment characteristics experienced on the special subframes. The different special subframe configurations may be differ among special subframe within the same or in a different radio frames or may be applied to a corresponding subframe in a neighboring cell. Over time, as changes to the communication environment are detected, the special subframe configurations may adapt to the communication environment characteristics.
