Abstract: Systems, procedures, and instrumentalities are disclosed for transmissions with polar codes. A transmitting entity may determine a mother code length. The mother code length may be based on value(s), e.g., a maximum number of transmissions. The transmitting entity may determine a number of information bits to be polar encoded. The number of information bits may be larger than a number of payload bits. The transmitting entity may map the number of information bits to a number of bit channels of a polar code. The transmitting entity may polar encode the information bits in the bit channels using the determined mother code length. The transmitting entity may partition the polar encoded bits into a number of parts. The number of parts may be based on one or more values, e.g., the maximum number of transmissions. The transmitting entity may transmit bits that have been interleaved to a circular buffer.

Abstract: Systems, methods, and instrumentalities are described herein for supporting CBG-based retransmission with variable CBG size using variable length HARQ-ACK. A WTRU may receive a configuration to use a first table. The first table may be associated with a maximum number of code block groups per transport block (maxCBG/TB). The WTRU may determine a number of HARQ-ACK bits to send for code blocks. The determination may depend on whether an indication is received to switch from the first table to a second table. On a condition that the indication to switch from the first table to the second table is received, the WTRU may send a number of HARQ-ACK bits that is equal to two times the maxCBG/TB. The WTRU may receive a retransmission of a number of code blocks, wherein a code block group size depends on a sent number of HARQ-ACK bits.

Abstract: Systems and methods described herein are provided for radiation pattern and modulation (RPM) based on channel-state information (CSI). The method may comprise receiving a set of bits; dividing the set of bits into at least three groups, wherein at least one group is size limited by a diversity order and selection factor applied by a CSI controller; mapping the groups to distinct control signals; generating a modulated RF signal and selecting at least one configurable antenna and a configuration of said at least one antenna based on the control signals; and transmitting the modulated RF signal through the at least one configured antenna.

Abstract: A method and system for determining beam reciprocity for a beam of a wireless transmit/receive unit (WTRU) are disclosed. A WTRU may determine a downlink (DL) beam for synchronization. Then, the WTRU may determine transmission reception point (TRP) transmit (TX)/receive (RX) beam correspondence information (BCI) using the determined DL beam. Further, the WTRU may determine a number of WTRU TX beams based on at least the TRP TX/RX BCI. Also, the WTRU may determine a set of WTRU TX beams based on at least the DL beam and the TRP TX/RX BCI, wherein determining the set includes determining one or more WTRU TX beam directions. In addition, the WTRU may transmit data using the determined set of WTRU TX beams. In an example, the determination of the TRP TX/RX BCI may be based on a received TRP TX/RX BCI.

Abstract: Systems, procedures, and instrumentalities are disclosed providing mixed data services such as mixed URLLC and eMBB services. In one example implementation, hierarchical modulation is dynamically configured and/or applied to provide the mixed services. The dynamic configuration and application of hierarchical modulation may be based on the respective priorities of the services and a condition of the concerned wireless network. The provision of the mixed services may utilize polar coding techniques. Control information may be mixed with data associated with the services.

Abstract: Systems, methods, and instrumentalities are disclosed for transmitting a message. For example, a first radio access technology, RAT, and/or a second RAT may be determined. The first RAT may be determined for reception of data. The second RAT may be determined for the reception of the data, perhaps for example based on an indication received via the first RAT. The data may be received via a first node associated with the first RAT and a second node associated with the second RAT.

Abstract: Systems, methods, and instrumentalities are disclosed for interleaving coded bits. A wireless transmit/receive unit (WTRU) may generate a plurality of polar encoded bits using polar encoding. The WTRU may divide the plurality of polar encoded bits into sub-blocks of equal size in a sequential manner. The WTRU may apply sub-block wise interleaving to the sub-blocks using an interleaver pattern. The sub-blocks associated with a subset of the sub-blocks may be interleaved, and sub-blocks associated with another subset of the sub-blocks may not be interleaved. The sub-block wise interleaving may include applying interleaving across the sub-blocks without interleaving bits associated with each of the sub-blocks. The WTRU may concatenate bits from each of the interleaved sub-blocks to generate interleaved bits, and store the interleaved bits associated with the interleaved sub-blocks in a circular buffer. The WTRU may select a plurality of bits for transmission from the interleaved bits.

Abstract: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beam in the beam group.
