Abstract: Aspects of the disclosure provide a slot structure (e.g., the arrangement of channels and pilot signals within a slot) that can relax the processing timeline for a wireless communication device. For example, in the first or initial symbol of a slot, control information may be frequency division multiplexed (FDM) with a demodulation reference signal (DMRS) or with user data. In some cases, delayed-processing data may be sampled, and the samples may be buffered at the receiving device, for processing later, after control information needed to process the data has been received and processed. Further aspects provide for payload pre-tapering. That is, when a device delays the processing of data bits, this can cause a processing bottleneck after that buffering delay. By virtue of various pre-tapering techniques described herein, the processing load needed to process the delayed-processing data can be reduced. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects provide for communicating a first set of broadcast reference signals (RSs) in a first subframe that includes a synchronization (SYNC) channel and communicating a second set of broadcast RSs in a second subframe that follows the first subframe. The second subframe may immediately follow the first subframe. A portion of the SYNC channel may include information indicating a configuration of broadcast RSs in one or more other subframes. The broadcast RSs may be configured for timing-error estimation, frequency-error estimation, and/or channel estimation. Additional and alternative aspects, embodiments, and features are also provided herein.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may select a two sets of reference signal resource elements (REs) for a symbol period, where each RE of the first set is contiguous to an RE of the second set. The base station may also identify resource element groups (REGs) for control signaling, where each REG covers one or more resource blocks (RBs). The base station may then perform interference cancellation, which may be based on an interference covariance matrix for each of the REGs. In some cases, the base station may coordinate with neighboring base stations (directly or through the core network) to ensure that the selected REGs do not partially overlap with reference signal transmissions or REGs of neighboring base stations.

Abstract: Certain aspects of the present disclosure provide techniques for compressing content using a neural network. An example method generally includes receiving content for compression. The content is encoded into a first latent code space through an encoder implemented by an artificial neural network trained to generate a latent space representation of the content. A first compressed version of the encoded content is generated using a first quantization bin size of a series of quantization bin sizes. A refined compressed version of the encoded content is generated by scaling the first compressed version of the encoded content into one or more second quantization bin sizes smaller than the first quantization bin size, conditioned at least on a value of the first compressed version of the encoded content. The refined compressed version of the encoded content is output for transmission.

Abstract: Various embodiments include methods and devices for implementing automatic grammar augmentation for improving voice command recognition accuracy in systems with a small footprint acoustic model. Alternative expressions that may capture acoustic model decoding variations may be added to a grammar set. An acoustic model-specific statistical pronunciation dictionary may be derived by running the acoustic model through a large general speech dataset and constructing a command-specific candidate set containing potential grammar expressions. Greedy based and cross-entropy-method (CEM) based algorithms may be utilized to search the candidate set for augmentations with improved recognition accuracy.

Abstract: Techniques are described for wireless communication. One method for wireless communication includes transmitting, to a user equipment (UE), an indication of a control channel subcarrier spacing to be used by the UE; and transmitting a control message having a subcarrier spacing in accordance with the indication. Another method for wireless communication includes transmitting, to a UE, an indicator channel identifying at least a subcarrier spacing to be used in one or more subsequent control channels. One or more subsequent control channels are then transmitted in accordance with the subcarrier spacing indicated by the indicator channel.

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: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for code rate selection for control channels. An exemplary method generally includes selecting, from a set of code rates, a code rate to be used to encode a stream of bits using a polar code, based on at least one of a downlink control channel aggregation size, an uplink control channel assignment, or a payload size of the stream of bits, encoding the stream of bits using the polar code and the selected code rate, and transmitting the encoded stream of bits.

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.
