1. A method of reconfiguring a time division duplex (TDD) uplink/downlink (UL/DL) configuration, the method comprising:
identifying, at a base station, a first TDD UL/DL predetermined configuration for a first radio frame; communicating data using the first TDD UL/DL predetermined configuration in the first radio frame; in response to a change in traffic ratio between UL and DL transmissions, identifying, at the base station, a second TDD UL/DL predetermined configuration for a second radio frame adjacent the first radio frame, the second TDD UL/DL predetermined configuration identified based, at least in part, on one or more subframes of the second TDD UL/DL predetermined configuration that can communicate at least one hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) indicator for a corresponding subframe of the first TDD UL/DL predetermined configuration, wherein the first TDD UL/DL predetermined configuration supports a greater number of HARQ processes than the second TDD UL/DL predetermined configuration, the HARQ processes are uplink (UL) HARQ processes communicating data using the second TDD UL/DL predetermined configuration in the second radio frame; storing excess UL HARQ processes in a queue; and upon receiving a negative new data indicator, executing a first UL HARQ process of the UL HARQ processes stored in the queue. |
