TRANSMITTING UPLINK CONTROL CHANNEL INFORMATION WHEN A CLEAR CHANNEL ASSESSMENT OF AN UNLICENSED CARRIER FAILS

摘要

Uplink control information may not be transmitted if a CCA of the unlicensed SCC fails. Thus, the present disclosure provide a solution in which uplink control information for an unlicensed SCC may still be transmitted when a CCA of the unlicensed SCC fails. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus generates uplink control information. The apparatus also attempts to perform a CCA of a carrier for an uplink burst. In addition, the apparatus determines a failure of the CCA. In addition, the apparatus performs one of the following when it is determined that the CCA has failed: transmitting the PUCCH transmission on the carrier in a later subframe of the uplink burst, transmitting the PUCCH transmission on the carrier in a different uplink burst, or transmitting the PUCCH transmission on a different carrier.

1. A method of wireless communication, comprising:
generating uplink control information; attempting to perform a clear channel assessment (CCA) of a carrier for an uplink burst; determining a failure of the CCA; and performing one of the following when it is determined that the CCA has failed:
transmitting the uplink control information on the carrier in a later subframe of the uplink burst;transmitting the uplink control information on the carrier in a different uplink burst; ortransmitting the uplink control information on a different carrier.
