Group ACK / NACK for LTE in unlicensed spectrum

摘要

Methods, systems, devices, and apparatuses for wireless communication are described. In one method, a set of one or more data subframes of a data frame may be transmitted over unlicensed spectrum to user equipment (UE) during a transmission period. A group hybrid automatic repeat request (HARQ) feedback message for a plurality of data subframes including at least one of the data subframes in the set of one or more data subframes is then transmitted to the UE during the transmission period. From the unlicensed spectrum. In another method, a set of one or more data subframes of a data frame may be received on the unlicensed spectrum during a transmission period. Group HARQ feedback messages for a plurality of data subframes including at least one of the data subframes in the set of one or more data subframes may then be transmitted on the unlicensed spectrum during the transmission period.
