摘要： 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.

摘要： A wireless transmit/receive unit (WTRU) may receive a constellation symbol that includes indications that each are associated with a respective WTRU of a plurality of WTRUs. The WTRU may determine that a first weight associated with a first indication of the indications is different than a second weight associated with a second indication of the indications. The indications may comprise indications of bits modulated at a multi-user constellation bit division multiple access modulator (MU-CBDMAM).

摘要： An apparatus and method for synchronization between a WTRU and a gNB are disclosed. The WTRU may receive a multiple beam synchronization signal from the gNB during synchronization. For each beam received by the WTRU, of the multiple beam synchronization signal, the WTRU may compare a received energy of the beam against a first threshold. A multiple beam synchronization signal may include a first and second synchronization signal (SS). If one or more beams of the multiple beam synchronization signal meets or exceeds the first threshold, the WTRU may report an indication of pre-synchronization to the gNB. This pre-synchronization may indicate to the gNB that a WTRU exists in an area of a particular beam of the WTRU. In this way, a gNB may target the WTRU using transmissions directed towards the WTRU.

摘要： Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

摘要： Maintaining time alignment with multiple carriers is contemplated. A group of uplink carriers (UL CC sets) that operate with a single Timing Advance (TA) may be determined, and a TA value may be applied to a specific UL CC set. A wireless transmit/receive unit's (WTRU) capability of using multiple TAs may define a group index of a few bits for each UL CC set. A TA Command received in a Random Access Response message may be used to apply the TA value to each UL carrier of the UL CC set. The WTRU may determine which UL CC set the TA value applies to based on which DL carrier the command was transmitted from. The WTRU may determine which UL CC set the TA value applies to based on the Group Index being explicitly provided in the command. The WTRU may release multi-CC configurations upon Time Alignment Timer (TAT) expiry.

摘要： A wireless transmit/receive unit (WTRU) may low-density parity-check (LDPC) encode data into LDPC blocks. Further, the WTRU may produce and append a cyclic redundancy check (CRC) to each of the LDPC blocks. Also, the WTRU may concatenate the plurality of LDPC blocks and appended CRCs. Additionally, the WTRU may produce information associated with error checks. Moreover, the WTRU may produce a codeword using a codebook. The codeword may be based on the information associated with the error checks. In addition, the WTRU may produce an orthogonal frequency-division multiplex (OFDM) signal by mapping the codeword and the concatenated plurality of LDPC blocks and appended CRCs onto resource elements of the OFDM signal. Further, the WTRU may transmit the produced OFDM signal. In a further example, the WTRU may produce an additional CRC in addition to the appended CRCs, and the produced OFDM signal may include the additional CRC.

摘要： Method and apparatus for transmission and reception of a Greenfield preamble are provided. In the method and apparatus, the Greenfield preamble may be a single user (SU) preamble or a multi user (MU) preamble. As an MU preamble, the Greenfield preamble includes a short training field (STF), a first long training field (LTF), a first signal (SIG) field, at least one additional LTF, and a second SIG field. Additionally, the Greenfield preamble may be utilized for efficient transmission and reception of control information to wireless devices, whereby the control information may be indicated using the STF, the first LTF, or the first or second SIG fields.
