According to some embodiments, a method of operation of a wireless transmitter in a wireless communication network comprises: encoding a set of information carrying data bits u of length K with a linear outer code to generate a set of outer parity bits p along with the data bits u; interleaving the set of outer parity bits p and the data bits u using a predetermined interleaving mapping function that depends on the number of data bits K and is operable to distribute some bits of the set of parity bits p in front of some data bits u; and encoding the interleaved bits using a Polar encoder to generate a set of encoded bits x. Various interleaving mapping functions are disclosed.

CRC interleaving pattern for polar codes

Systems and methods are described herein that allow information carrying bits of a transmission block to be placed at higher-reliability positions prior to transmission. An exemplary method includes generating a set of payload bits to be encoded for transmission, wherein the set of payload bits includes at least one known bit, interleaving the set of payload bits to generate an interleaved set of payload bits, wherein the interleaved set includes the at least one known bit in a predetermined position in the interleaved set, providing the interleaved set to a cyclic redundancy check (CRC) encoder to generate CRC-interleaved set of payload bits, wherein the CRC-interleaved set includes the at least one known bit in a predetermined position within the CRC-interleaved set, and encoding the CRC-interleaved set for transmission to a wireless device. Associated network nodes and wireless devices are included.

Bit order of NR PBCH payload to enhance polar code performance

A method for a controller to execute a program comprising a sequence of functions on an accelerator with a pipelined architecture comprising a microcode buffer. The method comprises executing a function of the program as a sequence of operations, wherein the sequence of operations is represented by a sequence of templates, determining whether the template is non-colliding with previously inserted templates in the microcode buffer, determining whether data in local memory will be referenced before all previously inserted templates have taken effect, determining whether registers will be referenced before all previously inserted templates in the microcode buffer have taken effect, when it is determined that the template fits, that resources are available, that local data memory accesses will not collide, and that register accesses will not collide: creating a sequence of microcode instructions in the template, and inserting the template into the microcode buffer.

Accelerator controller for inserting template microcode instructions into a microcode buffer to accelerate matrix operations

According to some embodiments, a method in a wireless transmitter comprises: obtaining a first set of bits (comprising a non-time-varying component) for wireless transmission; concatenating a second set of bits (comprising a time-varying component (e.g., beam identifier)) to the first set of bits; encoding the concatenated first and second set of bits using a channel code; and transmitting the encoded bits to a wireless receiver. In some embodiments, transmitting the encoded bits to the wireless receiver comprises transmitting a first beam. The method may further comprise: concatenating a third set of bits (comprising a time-varying component (e.g., beam identifier)) to the first set of wireless bits; encoding the concatenated first and third set of bits using a channel code; and transmitting the encoded bits to a wireless receiver using a second beam.

Polar coding for beam sweeping broadcast channel

According to some embodiments, a method for use in a wireless transmitter of adaptive cyclic redundancy check (CRC) length selection comprises: obtaining a system parameter related to a number of beam sweeps used by the wireless transmitter for transmitting a wireless signal; selecting a CRC length based on the obtained system parameter; selecting a CRC polynomial of the selected length; generating CRC bits from time-dependent or time-independent information bits using the CRC polynomial; concatenating the generated CRC bits with the time-dependent or time-independent information bits; encoding the concatenated bits; and transmitting the encoded bits to a wireless receiver. The system parameter may comprise: a carrier frequency; a number of transmit antenna elements; a number of receive antenna elements; a transmitter antenna azimuth configuration; a transmitter antenna elevation configuration; an antenna polarization type; a beam scanning algorithm; and a cell type.

Adaptive CRC length for beam sweeping

According to some embodiments, a method performed by a wireless device for polar encoding payload bits comprises: identifying payload bits of a data channel that have known values; placing a first subset of the known payload bits at input positions of a polar encoder that correspond to the earliest decoding bit positions of the polar encoder; placing a second subset of the known payload bits at input positions of the polar encoder that correspond to the least reliable decoding bit positions of the polar encoder after placement of the first subset of the known payload bits; and transmitting the polar encoded payload bits to a wireless receiver. The first subset of the known payload bits are placed in earliest decoding bit positions to improve early termination gain. The second subset of the known payload bits are placed in least reliable decoding bit positions to enhance error performance.
