Harq design for LTE in unlicensed spectrum utilizing individual ACK/NACK
First Claim
1. A method for wireless communications, comprising:
- transmitting, over an unlicensed spectrum to a user equipment (UE), a sequence number corresponding to a radio frame, wherein the sequence number is transmitted in a numerical order;
transmitting, over the unlicensed spectrum to the UE, one or more subframes of the radio frame; and
determining whether hybrid automatic repeat request (HARQ) feedback for the one or more subframes of the radio frame is received over the unlicensed spectrum from the UE, wherein, if the HARQ feedback for the one or more subframes of the radio frame is received, then the HARQ feedback for the one or more subframes of the radio frame indicates that the sequence number corresponding to the radio frame was received by the UE in the numerical order.

Abstract
Methods, systems, and apparatuses are described for wireless communications. In one method, a sequence number corresponding to a data frame and one or more data subframes of the data frame may be transmitted over an unlicensed spectrum to a user equipment (UE), and hybrid automatic repeat request (HARQ) feedback for the one or more data subframes may be received over the unlicensed spectrum, from the UE, when the sequence number corresponding to the data frame is received by the UE in a specified order. In another method, a sequence number corresponding to a data frame and HARQ feedback may be transmitted over an unlicensed spectrum to a UE, and one or more data subframes may be received over the unlicensed spectrum, from the UE, in response to the HARQ feedback when the sequence number corresponding to the data frame is received by the UE in a specified order.

17. A method for wireless communications, comprising:
-
receiving a transmission from a user equipment (UE); transmitting, in a radio frame over an unlicensed spectrum to the UE, a sequence number corresponding to the radio frame and hybrid automatic repeat request (HARQ) feedback for the transmission received from the UE, wherein the sequence number is transmitted in a numerical order; and determining whether one or more subframes in response to the HARQ feedback are received over the unlicensed spectrum from the UE, wherein, if the one or more subframes are received, then the one or more subframes indicate that the sequence number corresponding to the radio frame was received by the UE in the numerical order. - View Dependent Claims (18, 19, 20, 21)
