Abstract: A method at a scheduling entity might include determining that interference is present from a neighboring scheduling entity, which implements a second subcarrier spacing that is different from a first subcarrier spacing of the scheduling entity. The scheduling entity might request the neighboring scheduling entity to negotiate a bandwidth group (BWG), where the BWG is a bandwidth occupied by downlink subcarriers within which a transmission parameter is maintained. The method might include negotiating a bandwidth of the bandwidth group and transmitting, if negotiating is successful, downlink data to a scheduled entity served by the scheduling entity according to the negotiated bandwidth. The transmission parameter might be a precoder, rank, modulation order, power inside each BWG, or numerology. The numerology might be scalable and might be a combination of subcarrier spacing and cyclic prefix (CP) overhead, The subcarrier spacing might be scaled while keeping constant the CP overhead as a percentage of a symbol duration.

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 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: Certain aspects of the present disclosure relate to techniques and apparatus for increasing decoding performance and/or reducing decoding complexity. A transmitter may divide data of a codeword into two or more sections and then calculate redundancy check information (e.g., a cyclic redundancy check or a parity check) for each section and attach the redundancy check information to the codeword. A decoder of a receiver may decode each section of the codeword and check the decoding against the corresponding redundancy check information. If decoding of a section fails, the decoder may use information regarding section(s) that the decoder successfully decoded in re-attempting to decode the section(s) that failed decoding. In addition, the decoder may use a different technique to decode the section(s) that failed decoding. If the decoder is still unsuccessful in decoding the section(s), then the receiver may request retransmission of the failed section(s) or of the entire codeword.

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: Methods and apparatus for multiplexing reference signals for Multiple Input Multiple Output (MIMO) layers are provided. Resources for Demodulation Reference Signals (DMRS) corresponding to each of two or more data streams are assigned, wherein the resources assigned to each of the data streams are staggered in frequency and span two or more OFDM (Orthogonal Frequency Divisional Multiplexing) symbols. The DMRS is transmitted using the assigned resources.
