    摘要： The present invention is a system and method for recording right transfer in blockchain. There are three types of tokens, each of which may include a definition of rights. The rights can also be split or merged during circulation of tokens. The blockchain system ensures totality of rights does not increase nor decrease before and after circulation.

    摘要： Wireless devices may use polar codes for encoding transmissions and may support combining transmissions to improve decoding reliability (e.g., by achieving chase combining and incremental redundancy (IR) gains). For example, an encoding device may puncture a set of mother code bits using different puncturing patterns to obtain different redundancy versions for a first transmission and a re-transmission. Each puncturing pattern may correspond to an equivalent decoding performance. In some cases, to obtain equivalent puncture sets, the encoding device may perform punctured index manipulation procedures on an initial puncturing pattern. A punctured index manipulation procedure may involve switching a binary state for a binary bit at a same binary bit index for each puncture index in a puncturing pattern. A device may receive the transmissions generated using the equivalent puncture sets and may combine the information for improved decoding reliability.

    摘要： Methods, systems, and devices for wireless communications are described in which sequence groups, and sequence hopping patterns may be used to distinguish concurrent non-orthogonal multiple access (NOMA) transmissions. A wireless device, such as a user equipment (UE), may identify, for a message, a first transmission opportunity from a plurality of transmission opportunities associated with grant-free uplink contention-based transmissions (e.g., NOMA transmissions); select a multiple access (MA) signature sequence from a group of MA signature sequences associated with the first transmission opportunity; identify a hopping pattern associated with the MA signature sequence; and transmit one or more redundancy versions of the message in one or more of the plurality of transmission opportunities comprising the first transmission opportunity according to the MA signature sequence and the hopping pattern.

    摘要： Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices (e.g., base stations, user equipment (UEs), etc.) may utilize polar coding along with hybrid automatic repeat request (HARQ) techniques. In these systems, a device may encode bits for transmission by mapping information and parity check bits to a first set of polarized bit channels of a polar code. If this transmission is not successfully received at a decoding device, the encoding device may generate a HARQ retransmission. The device may copy information bits to a second set of polarized bit channels of a second polar code containing the first polar code and may assign parity check bits to the second set of bit channels for the copied information bits. These additional parity check bits for the repeated information bits may increase transmission reliability and may support improved early termination at the decoding device.

    摘要： A device may generate a first set of encoded bits by mapping an information bit vector to a first set of polarized bit channels of a first polar code according to a first bit index set, the first bit index set being based on respective bit channel reliabilities of the first set of polarized bit channels. The device may transmit the first set of encoded bits to another device over a wireless channel The device may receive an indication that a decoding of the first set of encoded bits was unsuccessful. The device may generate a second set of encoded bits by mapping a repetition of at least one bit to at least one bit channel of a second set of polarized bit channels of a second polar code according to a second bit index set. The device may transmit the second set of encoded bits to the other device.
