    Abstract: A wireless transmit/receive unit (WTRU) may, in a first codeword, map a first set of bits to a higher order modulation scheme and a second set of bits to a lower order scheme. The WTRU may then transmit the first set of bits in the first codeword at a first allocated power and the second set of bits in the first codeword at a second allocated power. In an example, the second allocated power may be great than the first allocated power. Further, the WTRU may determine the second allocated power based on power boosting the first allocated power. In another example, the WTRU may receive an assignment message from a base station including instructions regarding partition determination and resource assignment. The WTRU may then determine at least two partitions of bandwidth based on the assignment message. Further, each partition may have differing symbol periods, differing subcarrier spacing or both.

    Abstract: Methods, apparatuses, systems, devices, and computer program products directed to phase-continuous frequency selective precoding are provided. Included among these classes are methods for use in connection with dynamic precoding resource block group (PRG) configuration and with codebook based transmission configuration. A representative of such methods may include any of receiving signaling indicating transmit precoding information; determining a candidate PRG size using any of the transmit precoding information, a rule for determining a PRG size and configured PRG sizes; and configuring or reconfiguring a wireless transmit/receive device in accordance with the candidate PRG size. Another of the representative methods may include reporting a transmission coherence capability of a wireless transmit/receive unit; receiving a codebook subset restriction (CB SR) commensurate with the transmission coherence capability; determining a transmit precoding matrix indices (TPM1) size based on the CB SR; receiving a TPM1; and detecting or decoding the TPM1 based on the determined TPM1 size.

    Abstract: A wireless transmit/receive unit (WTRU) may modulate, based on a number of uplink control bits, a first sequence or the first sequence and a second sequence. The WTRU may spread the first sequence and the second sequence with a complementary sequence pair, concatenate parts of the first sequence and the second sequence in interlaced resource blocks (RBs), and perform an inverse discrete Fourier transform (IDFT) on the interlaced parts. The WTRU may transmit on a physical uplink control channel (PUCCH) a signal outputted by the IDFT.

    Abstract: Methods and systems for operation in a wireless network are provided, the methods including receiving modulated data symbols and zeros in a frequency-domain, and mapping in the frequency-domain the modulated data symbols and zeros in an interleaved manner to sub-carriers within a resource allocation. The methods and systems further include generating a time-domain data signal based on the mapped sub-carriers, and generating a time domain cancellation signal by sign inverting and repeating a predetermined number of time-domain samples at a tail portion of the data signal. The methods and systems further include combining the time-domain data signal and the time domain cancellation signal to generate an exact zero tail data signal such that the exact zero tail data signal has a zero tail length equal to the predetermined number of time-domain samples, and transmitting the exact zero tail data signal.
