The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure relates to encoding and decoding by using a polar code in a wireless communication system, and an operation method of a transmission-end apparatus includes determining segmentation and the number of segments, based on parameters associated with encoding of information bits, encoding the information bits according to the number of check bits, and transmitting the encoded information bits to a reception-end apparatus.

A bidirectional wireless power transfer system for transferring power comprises a power stage electrically connected to a transceiver element for an electric field and/or a magnetic field, and for extracting power from a generated electric field and/or a generated magnetic field. The power stage is for inverting an inputted power signal and for rectifying a received power signal. The system further comprises a trigger circuit for synchronizing wireless power transfer; and a clock generator for generating a clock signal. The system further comprises a switching element electrically connected to the power stage, and selectively electrically connected to the trigger circuit and the clock generator, such that: when the switching element electrically connects the clock generator to the power stage, the transceiver element is configured to transfer power by generating an electric field and/or a magnetic field, and when the switching element electrically connects the trigger circuit to the power stage, the transceiver element is configured to extract power from a generated electric field and/or a generated magnetic field.

This application provides example detection block sending and receiving methods, and network devices and systems. One example detection block sending method includes obtaining, by a network device, an original bit block data flow. At least one detection block is generated, and the at least one detection block is inserted into a position of at least one idle block in the original bit block data flow. The bit block data flow including the at least one detection block is then sent.

Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for rate-matching a stream of bits encoded using polar codes. An exemplary method generally includes determining a target coding rate, R.sub.T, for transmitting a group of K information bits, based on a first coding rate, R.sub.1, corresponding to a first target block error rate (BLER) for a first transmission of a first redundancy version (RV) of the packet and a second coding rate, R.sub.2, corresponding to a second target BLER for a last transmission of a last RV of the packet; determining a circular buffer size, N, of a circular buffer for use in transmitting the first RV and the last RV of the packet; generating encoded information bits from the K information bits using a polar code having a mother code size of N; writing the encoded information bits to the circular buffer; determining a maximum number of retransmissions, based on a latency requirement for the packet; generating different RVs from the encoded information bits in the circular buffer, each RV based on a corresponding target BLER; and transmitting the first RV via a wireless medium.

This disclosure provides a data retransmission method and apparatus. The method includes: A transmitting device obtains information to be transmitted for a t.sup.th time, where the information to be transmitted for the t.sup.th time includes R.sub.t extension locations and information to be transmitted for a (t−1).sup.th time, and the extension locations include M.sub.t information bits and L.sub.t check bits corresponding to the M.sub.t information bits. The transmitting device then performs Polar encoding on the information to be transmitted for the t.sup.th time, to obtain a codeword after the Polar encoding, obtains a codeword for (t−1).sup.th retransmission based on the codeword after the Polar encoding, and transmits the codeword for (t−1).sup.th retransmission. A receiving device performs polar decoding after receiving the codeword for (t−1).sup.th retransmission, to obtain a decoding result of codewords for t times of transmission. By performing, on an encoding side, check encoding on the information bits in an extension part, a decoding path can be reduced in a decoding process, thereby greatly reducing decoding complexity, and reducing storage overheads and calculation overheads.

A method for a terminal in a wireless communication system, according to the present disclosure, comprises the steps of: receiving a control signal; determining, from the control signal, a resource to which data can be mapped and then transmitted/received; and receiving data according to the determined resource for the data.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more sets of contiguous time domain resources for a multi-slot transmission occasion that spans at least multiple slots. The UE may select, for one or more codeblocks of a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on a per slot basis for each of the multiple slots, wherein start locations for bit selection for each of the multiple slots are determined independently from one another. The UE may interleave the coded bits to form one or more interleaved encoded bit sequences of the one or more codeblocks. The UE may transmit the communication including the one or more interleaved encoded bit sequences. Numerous other aspects are described.
