Abstract: Methods, apparatuses, and systems implemented by a transmitting node (TN), are provided. A representative method implemented by a TN may include generating a first set of polar coded bits (PCBs), sending the first set of PCBs or an interleaved copy of the first set of PCBs in a first transmission, and selecting one code generating operation (CGO) from a plurality of CGOs based on a number of shortened bits associated with the shortening operation. The method may also include storing in a circular buffer a second set of PCBs based on the first set of PCBs or a mother code block (MCB) in accordance with the selected CGO, on condition that the first transmission was not successful, outputting, from the circular buffer, a copy of a part of the second set of PCBs for transmission; and sending the copy of the second set of PCBs in a second transmission.

Abstract: A method performed by a WTRU may comprise generating a polar factor graph and pruning the polar factor graph to generate a pruned factor graph. The pruned factor graph may include input variable nodes, check nodes and output variable nodes. The method may further comprise the initializing input variable nodes. For each of a plurality of encoding levels of the pruned factor graph, values from the input variable nodes may be transferred to the check nodes. Operations, for example, XOR) additions, may be performed on the values of the check nodes. Check nodes having a single connection to another node not used in a previous transfer may be identified. Values from the identified check nodes may be transferred to the input variable nodes. Binary values from the input variable nodes may be transferred to the output variable nodes for transmission to a receiver.

Abstract: A method and apparatus are disclosed for establishing a low latency millimeter wave (mmW) backhaul connection. A base station may receive a mmW relay schedule from an evolved Node B (eNB) within one Long Term Evolution (LTE) scheduling interval. The base station may decode the mmW relay schedule, and initialize a mmW radio transmission resource according to the mmW relay schedule. The base station may receive a data packet from a second base station in a mmW transmission time interval (TTI) based on the mmW relay schedule using the initialized mmW radio transmission resource, and may transmit the data packet to a third base station based on the mmW relay schedule using the initialized mmW radio transmission resource. The transmitting may begin before the reception of the data packet is complete.

Abstract: Systems, devices and methods for a backscatter measurement based multiple RACH preamble transmissions are disclosed. A WTRU may receive a JCS-RS configuration comprising a minimum RACH preamble retransmission interval. The JCS-RS configuration may comprise a JCS backscatter power fraction (λ) of the WTRU transmit power (PTx). The WTRU may transmit a RACH preamble in a RACH occasion corresponding to a preferred SS/PBCH Index using an initial WTRU transmit beam, having an associated first RA-RNTI value. The backscatter power (PBS) may be measured using the WTRU receive beam corresponding to the WTRU transmit beam used for the RACH preamble transmission. On a condition that PBS>λPTx, the WTRU may retransmit the RACH preamble after a retransmission interval, on resources associated with a second RA-RNTI value. The WTRU may be configured for monitoring the PDCCH common search space with the first RA-RNTI and the second RA-RNTI, for respective RAR window intervals
