Abstract: Aspects of the present disclosure describe discovering physical cell identifiers in wireless communications. It can be determined to discover a physical cell identifier of one or more cells in a zone based at least in part on detecting a condition. A cell-specific signal can be received from at least one cell of the one or more cells in the zone. The cell-specific signal can be associated with one of a plurality of cell-specific signal hypotheses. The physical cell identifier of the at least one cell can be determined as one of a plurality of physical cell identifiers that corresponds to the one of the plurality of cell-specific signal hypotheses.

Abstract: Aspects of the disclosure relate to a channel coding and decoding algorithm that provides for generalized polar codes, including the concatenation of a plurality of component codes via one-step polarization. In a further aspect, selection of suitable component codes in this scheme can result in a generalized polar code having a cyclic shift property, such that information can be implicitly communicated according to the magnitude of the cyclic shift. In yet another aspect, a decoding algorithm provides for reliable decoding of such generalized polar codes, including exploitation of time diversity in sequential transmissions. Other aspects, embodiments, and features are also claimed and described.

Abstract: Wireless communication devices are adapted to facilitate multiplexing of reference signals. According to one example, a wireless communication device can multiplex a first reference signal and a second reference signal utilizing code division multiplexing for transmission across a first resource element and a second resource element. The first resource element may utilize a first subcarrier in a first OFDM symbol employing a first numerology. The second resource element may utilize a second subcarrier in a second OFDM symbol employing a second numerology that is different from the first numerology, where the second subcarrier overlaps in frequency at least a portion of the first subcarrier. The first and second OFDM including the multiplexed first and second reference signals may subsequently be transmitted. Other aspects, embodiments, and features are also included.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying a transmission timing of a control reference signal transmitted over a radio frequency spectrum band during an OFF duration of the UE with respect to the radio frequency spectrum band, in which the identified transmission timing is relative to a transition from the OFF duration to an ON duration of the UE with respect to the radio frequency spectrum band; receiving the control reference signal at the identified transmission timing; and performing a warm-up procedure, before the ON duration, based at least in part on the identified transmission timing of the control reference signal. A method for wireless communication at a wireless network includes indicating, to the UE, the transmission timing of the control reference signal; and transmitting the control reference signal at the indicated transmission timing. The OFF duration and the ON duration are coordinated with a wireless network.

Abstract: Methods, systems, and devices for outputting of codeword bits for transmission prior to loading all input bits. An example encoder may have multiple encoding branches. The encoder may divide the encoding branches into first and second encoding branch subsets, outputs of the first encoding branch subset being independent of inputs to the second encoding branch subset. The encoder may generate first and second subsets of output bits of a codeword in first and second encoding operations, the generating comprising inputting information bits of an information bit-vector and at least one frozen bit into respective encoding branches of the plurality of encoding branches and generating the first subset of output bits using the first encoding branch subset prior to generating the second subset of output bits using the second encoding branch subset. The encoder may output the first subset of output bits prior to outputting the second subset of output bits.

Abstract: Aspects of the present disclosure relate to pipelining two or more decoding stages during successive-cancellation polar code list decoding of a polar coded information transmission. During each cycle, the path metrics of candidate decoding paths of each of the pipelined decoding stages are compared and one of the candidate decoding paths from each pipelined decoding stage is selected for the next respective decoding stage.

Abstract: The described techniques relate to improved methods, systems, devices, or apparatuses that support enhanced efficiency in list Viterbi algorithm (LVA) decoding using iterative comparison trellis construction. Iterative comparison may involve comparison and selection from ordered accumulated path metrics associated with feeding transitions by selecting, for each successive rank of an ordered path metrics list for the current stage, the best unselected accumulated path metric of the feeding transitions. The iterative comparison may be performed sequentially for each stage before processing the next stage. Alternatively, the iterative comparison may be pipelined across stages, and different ranks of the ordered path metrics lists for different stages may be concurrently computed in a single trellis search cycle using multiple comparators. Iterative comparison may be used in an inner decoder to generate an ordered path metrics list for processing according to an error checking function using an outer decoder.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.

Abstract: A method of image compression includes receiving an image. Multiple quantized latent representations are generated to represent features of the image. Each of the quantized latent representations has a different resolution and is generated at staggered timings. Each of the later generated quantized latent representations is conditioned on each of the prior generated quantized latent representations. The multiple quantized latent representations are decoded to reconstruct the image.
