Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.

Abstract: Methods, systems, and devices for wireless communications are described that provide sequences of spreading codes and hopping patterns that may be used in non-orthogonal multiple access (NOMA) communications between a user equipment (UE) and a base station. A codebook of spreading codes and the associated hopping patterns may be systematically constructed by closed form formulas or look up table. The base station may receive multiple concurrent transmissions from multiple different UEs, and the sequences of spreading codes and hopping patterns, may be used to identify a particular UE of the multiple UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or multiple UEs may transmit a grant-free uplink transmission to a base station. The base station may monitor resources for the grant-free uplink transmission (e.g., from one or more UEs) and the base station may generate a group feedback message corresponding to whether the base station successfully received the uplink transmission(s). The group feedback message may contain feedback for multiple uplink transmissions from one or multiple UEs. The group feedback message may be transmitted to a UE over a downlink shared channel or a downlink control channel and the UE may receive the group feedback message and may determine whether to retransmit the uplink transmission based on the group feedback message.

Abstract: Aspects of the present disclosure relate to low density parity check (LDPC) coding utilizing LDPC base graphs. Two or more LDPC base graphs may be maintained that are associated with different ranges of overlapping information block lengths. A particular LDPC base graph may be selected for an information block based on the information block length of the information block. Additional metrics that may be considered when selecting the LDPC base graph may include the code rate utilized to encode the information block and/or the lift size applied to each LDPC base graph to produce the information block length of the information block.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine indices associated with m consecutive elements. In an aspect, each of the m consecutive elements may be associated with a different index. In addition, the apparatus may bit reverse a binary sequence associated with each of the m consecutive elements. In an aspect, each of the m consecutive elements may include a different binary sequence. Further, the apparatus may determine a bit-reversed order of the indices based at least in part on the bit-reversed binary sequence associated with each of the m elements. In addition, the apparatus may write each of the m consecutive elements to a different memory bank in parallel based at least in part on the bit-reversed order of the indices.

Abstract: Techniques are described for wireless communication. One method of wireless communication includes buffering a first set of coded bits including a first control message having a plurality of fields, buffering a second set of coded bits including a second control message having the plurality of fields, soft combining at least a first subset of the first set of coded bits and a second subset of the second set of coded bits in a combined set of coded bits, and decoding the first control message or the second control message based at least in part on the combined set of coded bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an offset value from a first modulation and coding scheme relating to a first code rate for a payload data transmission. The UE may determine, for a transmission of uplink control information, a second modulation and coding scheme, relating to a second code rate, that is different from the first modulation and coding scheme based at least in part on the offset value. The UE may transmit the uplink control information using the second modulation and coding scheme based at least in part on determining the second modulation and coding scheme. In some aspects, a UE may segment uplink control information. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a wireless device (e.g., a user equipment (UE) or a base station) may encode a codeword from a set of information bits using an LDPC code. The wireless device may then transmit multiple versions of the codeword to improve the chances of the codeword being received. In some aspects, the wireless device may use the techniques herein to generate self-decodable redundancy versions of the codeword to be transmitted to the receiving device. Accordingly, a receiving device may be able to identify information bits from one or more redundancy versions of the codeword even if the receiving device failed to receive an original transmission of the codeword.
