Abstract
Aspects described herein generally relate to communicating between a user equipment (UE) and a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell. An indicator can be transmitted from the cell and received by the UE to implement time division duplexing (TDD) on the uplink frequency band. Based at least in part on the indicator, communicating between the UE and the cell can include separating the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell.
Claims20
A method for providing flexible duplexing in wireless communications, comprising:
- communicating with a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell;
- receiving an indicator from the cell to implement time division duplexing (TDD) on the uplink frequency band;
- and
- communicating with the cell using TDD to separate the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell based at least in part on receiving the indicator.
An apparatus for providing flexible duplexing in wireless communications, comprising:
- at least one processor;
- and
- a memory communicatively coupled with the at least one processor;
- wherein the at least one processor is configured to:
- communicate with a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell;
- receive an indicator from the cell to implement time division duplexing (TDD) on the uplink frequency band, and
- communicate with the cell using TDD to separate the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell based at least in part on receiving the indicator.
An apparatus for providing flexible duplexing in wireless communications, comprising:
- means for communicating with a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell;
- means for receiving an indicator from the cell to implement time division duplexing (TDD) on the uplink frequency band;
- and
- means for communicating with the cell using TDD to separate the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell based at least in part on receiving the indicator.
