  • Patent number: 11071096
    Abstract: A method for transmitting uplink control information in a carrier aggregation environment, the method includes: calculating n pieces of response data, each having 1 bit or 2 bits, for n subframes received from an enhanced Node B (eNB) through n downlink component carriers and decoded by a User Equipment (UE); calculating k bits of integrated response data by applying a mapping rule reflecting a weight given to a downlink component carrier of each of the n pieces of response data; and performing a block coding of the integrated response data to produce encoded integrated response data, and transmitting the encoded integrated response data to the eNB.

  • Patent number: 11070317
    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.

  • Patent number: 11057156
    Abstract: Systems, methods, and instrumentalities may be provided for an infrastructure node to transmit and a wireless transmit/receive unit (WTRU) or a group of WTRUs to receive a first downlink control information (DCI) a second DCI. The first DCI may carry time critical DCI, whereas the second DCI may carry non-time critical DCI. Each of the first DCI and the second DCI may be polar encoded. The second DCI may be polar encoded may be received with an embedded first DCI as part of frozen bits. The second DCI may be mapped to a plurality of bit channels having higher reliability than the plurality of bit channels to which the embedded first DCI is mapped. The WTRU may discard the decoded first DCI, if decoding of the DCI using the embedded first DCI is not successful.

  • Patent number: 11050519
    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.

  • Patent number: 11005597
    Abstract: A wireless transmit receive unit (WTRU) may receive a Physical Downlink Control Channel (PDCCH) transmission and perform early termination on the PDCCH transmission. Transmissions that are not intended for the WTRU may be terminated. The WTRU may perform a first decode of the PDCCH transmission based on a first scrambling sequence. The first scrambling sequence may be generated using a Gold sequence, which may be initialized based on a WTRU identifier. If the first decode is not successful, the WTRU may determine that the PDCCH transmission is not intended for the WTRU. The WTRU may perform an assistance bit added (ABA) polar decode of the PDCCH transmission based on a second scrambling sequence (e.g., a cell radio network temporary ID (C-RNTI)). The WTRU may perform a CRC on the output of the ABA polar decode to obtain downlink control information (DCI).

  • Publication number: 20210058100
    Abstract: Systems, methods, and instrumentalities are described herein that may be used for reduced complexity polar encoding and decoding. There may be a set of encoding nodes to be used for polar encoding. An encoding node may be associated with a bit index and/or a relaxation level. A relaxation attribute may be selected for the encoding node. A relaxation group may be determined based on the relaxation attributes. The relaxation group may include two encoding nodes associated with consecutive bit indexes, an initial relaxation level, and the first relaxation attribute. A final relaxation level may be determined. Relaxation may be performed on the encoding nodes in the relaxation group. For example, an XOR operation between the encoding nodes may be omitted. Relaxation may be performed on the encoding nodes associated with each relaxation level up to the final relaxation level.

  • Publication number: 20200204305
    Abstract: Systems, methods, and instrumentalities are disclosed for narrowband (NB) LTE operation. A WTRU may receive a first downlink data transmission, for example, via a physical downlink shared channel (PDSCH). The WTRU may determine to send a hybrid automatic repeat request (HARQ) acknowledgment (ACK) in response to receipt of the first downlink data transmission. The WTRU may transmit a first uplink reference signal. The WTRU may indicate the HARQ-ACK using a first cyclic shift index that is applied to the first uplink reference signal. The WTRU may determine to send a HARQ negative ACK (HARQ-NACK), for example, on a condition that a second downlink data transmission is not correctly received. The WTRU may send a second uplink reference signal. The WTRU may indicate the HARQ-NACK using a second cyclic shift that is applied to the second uplink reference signal.
