Abstract: Methods, systems, and devices for wireless communication are described for mutual information based polar code construction. A wireless device may receive a codeword over a wireless channel, the codeword encoded using a polar code. The wireless device may identify a set of bit locations of the polar code corresponding to information bits of an encoded information bit vector. The set of bit locations may be determined based at least in part on a reliability order of the bit locations of the polar code, and the reliability order may be determined based at least in part on a recursive model that includes at least one mutual information transfer function that is applied at each polarization stage of multiple polarization stages of the polar code. The wireless device may decode the received codeword to obtain the information bit vector at the set of bit locations.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to decode or refrain from decoding a transport block (TB) transmitted from a base station based on a decodability condition. The decodability condition may include whether an effective UE throughput for decoding the TB is greater than a predetermined decoding throughput threshold or not. If the effective UE throughput is greater than the predetermined decoding throughput threshold, the UE may refrain from decoding the TB. In some cases, the TB may be a subsequent transmission from the base station based on an initial transmission not being correctly decoded, and the UE may refrain from decoding the subsequent transmission.

Abstract: Techniques are described herein that allow a user equipment (UE) to configure a subcarrier spacing value while monitoring synchronization signals of neighboring cells. In some wireless communication systems, synchronization signals in given radio frequency spectrum band may be transmitted using one of a plurality of different subcarrier spacings. In some cases, a network entity, such as a base station, may transmit an indication to the UE that indicates the subcarrier spacing used by a cell to transmit a specific set of synchronization signals. In some cases, the UE may select a subcarrier spacing based on a database of subcarrier spacings stored locally by the UE. In some cases, the UE may select the subcarrier spacing based on a predetermined configuration.

Abstract: Size ambiguity and false alarm rate reduction for polar codes. A user equipment (UE) may determine a decoding candidate bit sequence for a polar-encoded codeword having a codeword size based on a decoding hypothesis for control information having a particular bit length of multiple different bit lengths for the codeword size. The UE may calculate an error detection code (EDC) value for a payload portion of the decoding candidate bit sequence using an EDC algorithm, and may initialize an EDC variable state with at least one non-zero bit value. Scrambling or interleaving of bits may also be performed prior to, or after, polar encoding and may depend on the bit length. In examples, information bits may be bit-reversed prior to generating an EDC value. In examples, the encoded bits may include multiple EDC values to assist the UE in performing early termination and to reduce a false alarm rate.

Abstract: Methods, systems, and devices for wireless communication between a first wireless device and a second wireless device are described. A second wireless device may determine that a channel condition satisfies at least one channel condition threshold. The second wireless device may identify, based on the determination, a time-interleaved transmission scheme for block(s) of encoded information. The second wireless device may transmit the block(s) of encoded information to a first wireless device in accordance with at least the time-interleaved transmission scheme. In some instances, the first wireless device may determine that the channel condition satisfies the at least one channel condition threshold and send a message to the second wireless device in order to trigger the use of the time-interleaved transmission scheme.
