TECHNIQUES FOR MANAGING TRANSMISSIONS OF UPLINK DATA OVER AN UNLICENSED RADIO FREQUENCY SPECTRUM BAND |
摘要 |
Techniques are described for wireless communication. A first method may include performing a clear channel assessment (CCA) on an unlicensed radio frequency spectrum band; transmitting an indication of a time division duplexing (TDD) configuration over the unlicensed radio frequency spectrum band when the CCA is successful; and transmitting downlink data over the unlicensed radio frequency spectrum band in accordance with the TDD configuration when the CCA is successful. A second method may include performing a CCA on an unlicensed radio frequency spectrum band; dynamically determining, based at least in part on at least one grant to a user equipment (UE), and for a period following the CCA, a number of uplink subframes for communication over the unlicensed radio frequency spectrum band; and transmitting downlink data over the unlicensed radio frequency spectrum band in accordance with the timing of the number of uplink subframes when the CCA is successful. |

1. A method for wireless communication, comprising:
receiving, at a user equipment (UE), an indication of a time division duplexing (TDD) configuration over an unlicensed radio frequency spectrum band, wherein the indication of the TDD configuration comprises at least one of: an indication of a consecutive number of downlink subframes, an indication of a consecutive number of uplink subframes, or a grant associated with an unlicensed radio frequency spectrum band; performing a clear channel assessment (CCA) on the unlicensed radio frequency spectrum band at a beginning of an uplink period in accordance with the TDD configuration; and transmitting uplink data from the UE over the unlicensed radio frequency spectrum band in accordance with the TDD configuration when the CCA is successful. |
