Embodiment Construction

[0031] As will be appreciated by those skilled in the art, aspects of the embodiments may be embodied as a system, apparatus, method or program product. Accordingly, embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, microcode, etc.), or an embodiment combining software and hardware aspects, both of which are generally referred to herein as Called a "circuit", "module" or "system". Furthermore, embodiments may take the form of a program product embodied in one or more computer-readable storage devices stored in machine-readable code, hereinafter referred to as code, computer-readable code, and / or program code. A storage device may be tangible, non-transitory, and / or non-transitory. Memory devices may not exhibit a signal. In a certain embodiment, the storage device only employs the signal for accessing the code.

[0032] Certain functional units described in this specification may be labe...

Abstract

Methods and apparatuses for HARQ-ACK codebook transmission on unlicensed spectrum are disclosed. A remote unit comprising: a receiver that receives, from a base unit, one or multiple downlink transmissions within a channel occupancy time initiated by the base unit, a first message indicating a first candidate opportunity for transmission of a Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) codebook corresponding to the one or multiple downlink transmissions and a second message indicating a number of allowed opportunities for transmission of the HARQ-ACK codebook; a processor that determines the HARQ-ACK codebook and a number of total candidate opportunities for transmission of the HARQ-ACK codebook; and a transmitter that, in response to a channel access for the first candidate opportunity being successful, transmits the HARQ-ACK codebook in the first candidate opportunity, and, in response to the channel access for the first candidate opportunity being failed and the number of the total candidate opportunities being larger than one, attempts to transmit the HARQ-ACK codebook in a second candidate opportunity.
