Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify one or more sidelink positioning reference signal burst patterns identifying one or more bursts of sidelink positioning reference signals that are to be transmitted by either the UE or by other sidelink UEs. The UE may schedule transmission of a sidelink data message to occur during a same time period that includes the one or more bursts of sidelink positioning reference signals. The UE may transmit the sidelink data message via first resource elements that are different from second resource elements on which the one or more bursts of sidelink positioning reference signals are transmitted.

A system and a method are disclosed relating to a transport block processing chain for a transmitter. A code block determination circuit may be configured to determine a size of a code block that maps across multiple slots of a wireless physical shared channel according to a Transport Block over Multiple Slots (TBoMS) configuration, and a rate matching circuit may be configured to rate match bits of the code block to a number of bits available in a transport block that spans the predetermined number of slots of the wireless physical shared channel. Additionally, an interleaver may be configured to interleave a continuous output of the rate matching circuit on a slot basis so that a code block that crosses a slot boundary between a first slot and a second slot is interleaved within the first slot and the second slot.

The disclosure relates to a method of performing communication in a wireless communication system. According to an embodiment of the disclosure, a terminal may receive physical downlink control channel (PDCCH) configuration information and rate matching configuration information from a base station, identify resource elements (REs) overlapping a rate matching resource from among REs included in PDCCH candidates, based on the PDCCH configuration information and the rate matching configuration information, and monitor a PDCCH candidate including the identified REs from among the PDCCH candidates, based on whether a number of ports of signals transmitted via the rate matching resource exceeds a preset value.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for applying non-linearity to digital subcarriers. A receiver includes a detector circuit operable to receive a first optical signal over an optical link, the first optical signal carrying first data. The receiver includes a carrier recovery estimation circuit operable to generate compensated data by correcting errors in the first data. The receiver includes a non-linear coefficient estimation circuit operable to (i) receive the compensated data, and (ii) estimate one or more non-linear coefficients, wherein information indicative of the estimated non-linear coefficients is transmitted over an optical network, such that a second optical signal is transmitted based, at least in part, on the estimated non-linear coefficients, the second optical signal being received by the receiver.

A transmitter is provided. The transmitter includes: a low density parity check (LDPC) encoder configured to encode input bits to generate an LDPC codeword including the input bits and parity bits; a repeater configured to select at least a part of bits constituting the LDPC codeword and add the selected bits after the input bits; and a puncturer configured to puncture at least a part of the parity bits.

The method and apparatus for polar encoding and rate-matching are disclosed.

A transmitter is provided. The transmitter includes: an outer encoder configured to encode input bits to generate outer-encoded bits including the input bits and parity bits; a zero padder configured to generate a plurality of bit groups each of which is formed of a same number of bits, maps the outer-encoded bits to some of the bits in the bit groups, and pads zero bits to remaining bits in the bit groups, based on a predetermined shortening pattern, thereby to constitute Low Density Parity Check (LDPC) information bits; and an LDPC encoder configured to encode the LDPC information bits, wherein the remaining bits in which zero bits are padded include some of the bit groups which are not sequentially disposed in the LDPC information bits.

A polar encoding and decoding method and apparatus are provided. The method includes: obtaining K to-be-encoded bits; selecting K sequence numbers from a first sequence, where the to-be-encoded bits are placed on polar channels corresponding to the K sequence numbers; and performing polar code encoding on the K to-be-encoded bits to obtain encoded bits, where the first sequence includes sequence numbers of N polar channels, and the first sequence is one or a subsequence of a related sequence. This technical solution is applicable to a short message communication system of a BeiDou satellite. The method can effectively improve performance of the communication system and reduce complexity.

The disclosure relates to a communication technique for convergence between an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system thereof. The disclosure may be applied to intelligence services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety related services, etc.) based on a 5G communication technology and an IoT-related technology. The disclosure provides a method for transmitting uplink control information and/or uplink data by a terminal according to multiple priorities, a method for receiving uplink control information and/or uplink data by a base station according to multiple priorities, and an apparatus therefor.

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. The UE may select, for a communication on the multi-slot transmission occasion, coded bits of a plurality of coded bits on one of the per slot basis or the per segment basis, for each of a plurality of segments, each segment including one of the one or more sets of contiguous time domain resources and spanning across at least two slots. The UE may interleave the coded bits on one of the per slot basis or the per segment basis to form one or more interleaved encoded bit sequences of a codeblock. The UE may transmit the communication including the one or more interleaved encoded bit sequences. Numerous other aspects are provided.
