Group acknowledgement/negative acknowledgement and triggering GACK/channel state information
First Claim
1. A method of wireless communication, comprising:
- generating uplink control information (UCI), the UCI including at least one of a group acknowledgement/negative acknowledgement (GACK), a rank indicator (RI), or a channel state information (CSI) transmission; and
sending a UCI transmission in a listen before talk (LBT) subframe, wherein the generating the UCI comprises coding and multiplexing the GACK, the RI, or the CSI separately when the UCI transmission is sent in an uplink data channel, and wherein the generating the UCI comprises coding the GACK, the RI, or the CSI jointly when the UCI transmission is sent in an uplink control channel.

Abstract
According to the present disclosure, CSI and/or a plurality of ACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. Once the trigger is received, the UE may transmit the CSI and/or GACK to the eNB. In this way HARQ feedback and/or CSI may be reliably communicated while reducing payload. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus send, to a UE, data transmissions associated with a first plurality of downlink subframes. In an aspect, the apparatus increments a counter for each data transmission sent to the UE. In a further aspect, the apparatus transmits, to the UE, a first trigger for a first GACK when a counter is greater than or equal to a threshold.
