Abstract
Embodiments of the invention use signaling mechanisms that enable dynamic reconfiguration of the UL/DL resource partitioning by user equipment (UE) in a TDD wireless communication system, such as the 3GPP TDD Long Term Evolution (TD-LTE) system. The dynamic reconfiguration of the UL/DL resource partitioning disclosed herein may also be applied to any other TDD wireless system employing dynamic reconfiguration of the TDD UL/DL configuration.
Claims22
A method, comprising:
- receiving, at a user equipment (UE) in a time division duplex (TDD) wireless communication system, a cell-specific TDD uplink (UL)/downlink (DL) configuration for a plurality of radio frames;
- notifying a base station in the TDD wireless communication system that the UE has adaptive TDD capabilities;
- detecting, at the user equipment, a dynamic reconfiguration signal for an assigned TDD UL/DL configuration;
- and
- restricting activation of the signaled TDD UL/DL configuration at the UE to occur only at future radio frame boundaries.

A user equipment device, comprising:
- a processor circuit configured to:
- receive a cell-specific time division duplex (TDD) uplink (UL)/downlink (DL) configuration for a plurality of subframes within a radio frame;
- detect a dynamic reconfiguration signal for an assigned TDD UL/DL configuration;
- and
- restrict reconfiguration of a TDD UL/DL configuration to occur only at future radio frame boundaries.
