Embodiment Construction

[0050] 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 include an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, microcode, etc.), or a mixture thereof, which may be generally referred to herein as 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 as machine-readable code, computer-readable code, and / or program code, hereinafter referred to as "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 the access code.

[0051] Certain functional units described in this specification may be labeled as "modules" in order to more specifically emphasize...

Abstract

Apparatus and method for CBG-based retransmission are disclosed. An apparatus comprising: a receiver that receives a first number of TBs, wherein each TB includes a second number of code block groups(CBGs); a processor that decodes the first number of TBs; and a transmitter that transmits a signaling comprising a first field corresponding to the first number of TBs and a second field corresponding to the CBGs included in a third number of TBs, wherein the third number of TBs are the incorrectly decoded TBs in the first number of TBs.

Description
