Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining whether to transmit an uplink transmission scheduled by a semi-static grant or a dynamic uplink transmission scheduled by a dynamic grant when the dynamic uplink transmission conflicts with the uplink transmission scheduled by the semi-static grant. In particular, if a user equipment (UE) determines that a dynamic grant is received within a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the uplink transmission scheduled by the semi-static grant and refrain from transmitting the dynamic transmission. Alternatively, if the UE determines that a dynamic grant is received in advance of a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the dynamic transmission and refrain from transmitting the uplink transmission scheduled by the semi-static grant.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to determine a priority indicator for an upcoming transmission between the UE and a base station and transmit the priority indicator to the base station. The base station may receive the priority indicator, determine a network condition, and may transmit control information for a downlink transmission. The control information may include an indication of a set of modulation and coding schemes to select from a plurality of sets of modulation and coding schemes and an index value for an entry in the selected set of modulation and coding scheme, where the indication is based on the priority indicator and a network condition. The UE may identify a combination of a modulation order and a code rate for the downlink transmission based on the indication of modulation and coding scheme table and the index value.

Abstract: Methods, systems, and devices for wireless communication are described. To encode a vector of bits using a polar code, an encoder may allocate information bits of the vector to polarized bit-channels associated with a channel (e.g., a set of unpolarized bit-channels) used for a transmission. In some cases, the polarized bit-channels may be partitioned into groups associated with different values of some associated reliability metric (s). The information bits may be allocated to the polarized bit-channels based on the reliability metrics of the different polarized bit-channels and the overall capacity of a transmission. That is, the bit locations of a transmission may depend on the reliability metrics of different polarized bit-channels and the overall capacity of the transmission. To facilitate puncturing, the overall capacity of the transmission may be adjusted and the unpolarized bit-channels may be partitioned into polarized bit-channels based on the adjusted capacity.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may assign a set of preamble blocks for autonomous uplink transmissions from a preamble block pool. A user equipment (UE) may identify indices for each of a set of indexed sequences to be transmitted over the set of preamble blocks. The UE may select or identify the indices by performing an encoding procedure on a set of parameters. The indices may be applied to the pool of indexed sequences, and the resulting set of sequences may be transmitted over the set of assigned preamble blocks. The base station may recognize composite sequences transmitted from UEs on respective sets of preamble blocks based on the set of sequences. Thus, the base station may identify a data transmission from the UE based on monitoring for and identifying the set of sequences transmitted on the preamble blocks.

Abstract: Decoding and encoding methods, systems, and devices for wireless communication are described. One method may include receiving a codeword over a wireless channel, the codeword being encoded using a polar code, identifying a set of repeated bit locations in the received codeword, and identifying a set of bit locations of the polar code used for information bits for the encoding. The set of bit locations may be determined based at least in part on recursively partitioning bit-channels of the polar code for each stage of polarization and assigning portions of a number of the information bits to bit-channel partitions of each stage of polarization based on a mutual information transfer function of respective aggregate capacities of the bit-channel partitions. The method may also include decoding the received codeword according to the polar code to obtain an information bit vector at the set of bit locations, and other aspects and features.

Abstract: Techniques are described herein related to communicating a quality of service (QoS) class identifier (QCI) for configuring physical (PHY) layer signaling. The QCI may be used to configure one or more transmission parameters of a device (e.g., a user equipment (UE) or a base station) at a PHY layer. The PHY layer may select the one or more transmission parameters to meet the QoS conditions of a given QoS class of a transport block being communicated. A modulation and coding scheme (MCS) value may be used as the QCI for the PHY layer, a channel quality indicator (CQI) value may be used as the QCI for the PHY layer, or a cell radio network temporary identifier (C-RNTI) may be used as the QCI for the PHY layer. In some cases, the QCI may be a single bit included in a downlink control message.

Abstract: Wireless communication methods, systems, and devices capable of utilizing base graphs for error correction techniques. A base graph can be used to derive a low-density parity-check (LDPC) code used for encoding a retransmission of an original transmission in a wireless communication system. An exemplary method generally includes selecting, based on a modulation and coding scheme (MCS) and a resource allocation (RA) for transmitting a codeword, a base graph (BG), from which to derive a low density parity check (LDPC) code for use in encoding data bits in the codeword (e.g., encoding data bits of a bitstream such that some redundant bits are included in the codeword), encoding the data bits to generate the codeword using the LDPC code derived from the selected BG, and transmitting the codeword using the MCS via resources of the RA.

Abstract: Techniques for wireless communication are described. A method of wireless communication at a user equipment (UE) includes receiving a synchronization signal within a synchronization signal (SS) block; receiving at least a portion of a physical broadcast channel (PBCH) of the SS block, the PBCH comprising a self-decodable portion and an outside portion; and decoding the PBCH based at least in part on receiving the self-decodable portion of the PBCH. The synchronization signal has a first bandwidth. The self-decodable portion of the PBCH has a second bandwidth substantially within the first bandwidth. The outside portion having a bandwidth that is outside of the second bandwidth and within a PBCH bandwidth, the PBCH bandwidth being greater than the first bandwidth.

Abstract: Methods, systems, and devices for wireless communications that support inter-user equipment (UE) coordination (IUC) for beamformed communications are described. A first UE may receive, using a first spatial filter, a first sidelink control message including a first sidelink resource reservation associated with a second UE. Additionally, or alternatively, the first UE may receive, using a second spatial filter, a second sidelink control message including a second sidelink resource reservation associated with a third UE. The first UE may transmit, to the second UE or the third UE, an IUC message that indicates a conflict between the first sidelink resource reservation and the second sidelink resource reservation. The IUC message that indicates a conflict may be based on a relationship between the first spatial filter used to receive the first sidelink resource reservation and the second spatial filter used to receive the second sidelink resource reservation.
