Reduced numbers of encoded bits obtained by encoding input bits by a polar code are incrementally output, for transmission for example. The polar code comprises bit indices for placing bit values before encoding. The bit indices include a first set of bit indices for placing values of the input bits and a second set of bit indices for placing a predetermined bit value. A first reduced number of the encoded bits start from a first starting position, and a second reduced number of the encoded bits start from a second starting position different from the first starting position. The second reduced number of the encoded bits include one or more of the encoded bits not included in the first reduced number of the encoded bits. The reduced numbers of encoded bits may be output from continuous positions, in a circular buffer for example, or may include repeated bits.

The reduced number of encoded bits obtained by encoding the input bits by the polar code is incrementally output, for example for transmission. The polar code includes a bit index for placing bit values prior to encoding. The bit indices include a first set of bit indices for placing values of the input bits; a second set of bit indices for placing predetermined bit values. A first reduced number of the coded bits begins from a first starting position and a second reduced number of the coded bits begins from a second starting position different from the first starting position. The second reduced number of coded bits includes one or more of the coded bits not included in the first reduced number of coded bits. For example, the reduced number of encoded bits may be output from consecutive locations in a circular buffer, or may include duplicated bits.

Methods, systems, and devices for wireless communications are described. An example method includes receiving a first transmission of one or more code blocks in a first slot and transmitting uplink control information that includes acknowledgement information for the one or more code blocks. The method also includes receiving a scheduling signal that indicates one or more parameters associated with a re-transmission scheduling policy based at least in part on the acknowledgement information. The method also includes receiving a second transmission of at least a portion of the one or more code blocks in a second slot and decoding the second transmission of at least the portion of the one or more code blocks according to the re-transmission scheduling policy.

Methods, systems, and devices for wireless communications are described. A wireless communications system may support transmission of feedback information for downlink data information in multiple feedback payloads across multiple uplink channel slots. For a downlink channel carrying first data information, a user equipment (UE) may transmit feedback information for the data information in two or more uplink channel transmission occasions. A first payload transmitted during a first uplink channel occasion and a second payload transmitted during a second uplink channel occasion may have overlapping information, such as feedback information for the first data information, but may not be identical. The first payload may include feedback information for a first set of downlink channel transmissions, and the second payload may include feedback information for the first set of downlink channel transmissions and a second set of downlink channel transmissions.

A user equipment (UE) may transmit, to a network node, an indication of support for a decoder success prediction capability. The network node may obtain the indication of support by the UE for the decoder success prediction probability. The network node may output a transmission for the UE including one or more parameters based on the indication of support by the UE for the decoder success prediction capability. The UE may receive the transmission including one or more code blocks based on the indication of support for the decoder success prediction capability. The network node may optimize a multiple incremental redundancy scheme (MIRS) schedule for at least one of transmitting the transmission or retransmitting the transmission based on the indication of support by the UE for the decoder success prediction capability. The transmission may include the MIRS schedule.

Methods, systems, and devices for wireless communication are described. Multiple incremental redundancy scheme (MIRS) may be an SPEF adaptation scheme for finding an optimal spectral efficiency (SPEF) for transmission of transport blocks. The network may transmit a scheduling and signaling framework to allow multiple transport blocks to be scheduled in a single downlink resource allocation for transmission with the MIRS. For example, a network may schedule a single resource allocation for transmission of multiple transport blocks from the network to a UE. The plurality of transport blocks may include at least an initial transmission of a new transport block and / or a retransmission of any transport block from a previously allocated receiver that cannot be successfully decoded.

Methods, systems, and devices for wireless communication are described. Techniques described herein provide for reporting a capacity gap (G2C metric in a multiple incremental redundancy scheme (MIRS). The receiver may transmit information to the transmitter indicative of thermal noise or interference associated with the G2C metric. The transmitter may transmit a number of coding bits to the receiver based on the G2C metric and noise or interference associated with the G2C metric. In some examples, a transmitter may transmit signaling to a receiver indicating a configuration for reporting a G2C metric, noise data associated with the G2C metric, and interference data.

This disclosure describes a module and method for transmitting codewords in a wireless communication system using an incremental redundancy-hybrid automatic repeat request (IR- HARQ) scheme. Each of the codewords comprise information-bit sequences that have been encoded based on a parity check matrix (PCM) that was derived from a lifted base matrix of a rate-compatible root-protograph low-density parity-check (RC-RP-LDPC) protograph.
