Abstract: A wireless transmit/receive unit (WTRU) may receive assignment information for receiving a first codeword using a first modulation and coding scheme (MCS) in a first set of resource blocks (RBs), and a second codeword using a second, different MCS in a second set of RBs. The first and second sets of RBs may be in a first time interval in a first bandwidth part using a first subcarrier spacing. The WTRU may receive, in symbols of the first time interval in the first bandwidth part, the first codeword using the first MCS in the first set of RBs and the second codeword using the second, different MCS in the second set of RBs. At least a portion of the first codeword and at least a portion of the second codeword may be received in at least a first symbol in the symbols in the first time interval.

Abstract: When the codeword level interference cancellation (CW-IC) is used at the receiver in conjunction with the superposition coding scheme at the transmitter, it is helpful if the soft buffer at the receiver is reserved not only for the desired transport blocks (TBs) but also for the interfering TBs handled by the CW-IC. In so doing, the soft channel bits of interfering TBs at multiple (re)transmissions can be combined to enhance the success rate of data decoding. A soft buffer partition method for the soft channel bits of the desired and interfering TBs in the superposition coding scheme is proposed. The proposed method has a full flexibility in adjusting the soft buffer sizes for the desired and interfering TBs.
