Dynamic uplink and downlink configuration using flexible subframes
First Claim
1. A non-transitory computer readable medium comprising instructions that, when executed by one or more processors of an evolved Node B (eNodeB), configure the eNodeB to:
- transmit, by the evolved Node B (eNodeB) to a user equipment (UE), a System information Block Type 1 (SIB1) including first uplink and downlink subframe configuration information; and
transmit, by the eNodeB to the UE, in at least one downlink subframe of a radio frame configured in the first uplink and downlink subframe configuration, second uplink and downlink subframe configuration information, the second uplink and downlink subframe configuration information included in a downlink control information (DCI) message and the DCI message being included in the at least one downlink subframe of the radio frame,wherein the DCI message is configured to dynamically change the uplink and downlink frame structure configuration from the first uplink and downlink subframe configuration information of the SIB 1 to the second uplink and downlink subframe configuration of the DCI message.

Abstract
An apparatus and method for dynamically changing an uplink and downlink ratio configuration is disclosed herein. An evolved Node B (eNodeB) operating in a wireless communications network transmits a System Information Block Type 1 (SIB1) including first uplink and downlink ratio configuration information. The eNodeB also transmits in at least one downlink subframe of a radio frame configured in the first uplink and downlink ratio configuration second uplink and downlink ratio configuration information. The second uplink and downlink ratio configuration information is included in a downlink control information (DCI) message. The DCI message is included in the at least one downlink subframe of the radio frame.

15. An apparatus of a user equipment (UE) operating in a wireless communications network comprising:
-
memory; and one or more processors coupled to the memory and configured to; receive a system information data block comprising a System Information Block Type 1 including a first uplink and downlink configuration from a base station and to subsequently receive in at least one downlink subframe of a radio frame configured in the first uplink and downlink configuration, second uplink and downlink configuration information provided in a downlink control information (DCI) format; and blind decode each received downlink subframe, including the at least one downlink subframe, to detect the second uplink and downlink configuration information and to initiate a dynamic changing of the uplink and downlink frame structure configuration from the first uplink and downlink subframe configuration of the SIB 1 to the second uplink and downlink subframe configuration of the DCI message. - View Dependent Claims (16, 17, 18, 19, 20)
