Abstract: Various embodiments include methods for demodulating wireless transmission waveforms to reconstruct data tones, performed in receiver circuitry of a wireless communication device. The methods may include receiving time domain wireless transmission waveforms that include time domain peak reduction tones (PRTs) that were generated by a set of PRT neural networks using time domain data signals derived from frequency domain data tones in another wireless communication device, reconstructing the time domain data signals from the time domain wireless transmission waveforms using a receiver neural network that has been trained in conjunction with the set of PRT neural networks to generate a time domain reconstruction of data signals, and transforming the time domain reconstruction of data signals to a frequency domain reconstruction of data tones.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request for sets of neural network weights, each set corresponding to a neural network, to one or more network entities. The one or more network entities may transmit multiple sets of neural network weights to the UE in response to the request. The UE may run a classifier neural network on the sets of neural network weights to select a set of neural network weights corresponding to a neural network. The UE may transmit a neural network identifier to the one or more network entities that transmitted neural network weights.

Abstract: Methods, systems, and devices for wireless communication are described, which may be employed for wireless communication in contention-based (e.g., unlicensed or shared) spectrum. An aperiodic channel state information (CSI) reference signals (RS) may be used for channel quality indicator (CQI) measurements, for example. A user equipment (UE) may receive signaling to indicate the presence of CSI RS and may receive the CSI RS according to the signaling. The UE may then compute a CQI based on CSI RS, and transmit the CQI in a report to a base station. In some examples, a quasi-periodic CSI RS is used. For instance, the UE may determine a different location for the CSI RS. For example, the UE may identify a periodic anchor subframe, and locate the CSI RS based on constant offset from the anchor subframe. Periodic or a clear-channel-assessment-exempt transmission based CSI RS examples are also described.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system may support techniques for using non-staggered reference signals to increase the efficiency of the system and reduce the complexity of channel estimation. A base station may schedule a transmission to a user equipment (UE) including pilot tones mapped to a first symbol and a second symbol. In some cases, the pilot tones on the first and second symbols may be non-contiguous, and the base station may scramble the pilot tones on the first and second symbols according to the same scrambling sequence. In other cases, the pilot tones on the first and second symbols may be contiguous, and the pilot tones may be scrambled according to the same or different scrambling sequences. These techniques may result in reduced complexity for interference estimation and channel estimation at a UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may explicitly or implicitly identify one or more parameters associated with a user equipment (UE), and may classify the UE into a cluster of UEs based on identifying the one or more parameters. The base station may determine a customized function block based on classifying the UE into the cluster of UEs. For example, the base station may determine the customized function block based on determining whether the cluster of UEs is associated with a pre-trained customized function block. The base station may then transmit the customized function block to the UE. The UE may receive the customized function block and may process one or more signals at the UE based on the received customized function block.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a set of parameters to determine a valid timing advance (TA) to transmit data using preconfigured uplink resources (PUR) during an idle or inactive mode. In some cases, the parameters are one or more TA commands and one or more conditions associated with each TA command. The UE may identify the current condition of the UE and determine whether the current condition of the UE matches one of indicated conditions. The UE may select a TA command based on finding a match and use the TA command to transmit an uplink PUR transmission. Additionally or alternatively, the parameters may be neural network parameters that indicate a neural network model that the UE may use to determine a TA command associated with a valid TA based on the current condition of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a request that the UE report a predicted future channel state information measurement. Upon receiving the request, the UE may measure, during a first time period, a channel to obtain measured channel state information. The UE may then determine the predicted future channel state information for a second time period based on the measured channel state information. In some case, the second time period may be subsequent to the first time period. Upon determining the predicted future channel state information measurement, the UE may transmit, to the base station, a channel state information report. In some aspects, the channel state information report may be indicative of the predicted future channel state information measurement.

Abstract: Wireless communication apparatus and methods related to dynamic TDD are described. In aspects, a method of wireless communication over a shared medium may include, receiving, from a base station, control information in a first portion of a transmission opportunity (TXOP), wherein the control information indicates a configuration for triggering a communication of at least one shared medium reservation signal associated with one or more remaining portions of the TXOP; and in response to receiving the control information in the first portion of the TXOP, monitoring for or transmitting the at least one shared medium reservation signal, based on the configuration.

Abstract: Wireless communications systems and methods related to spectrum pooling among multiple carriers or operators for peak rate performance improvement are provided. A first wireless communication device communicates, with a second wireless communication device, a first reservation request signal to reserve a transmission period in a frequency spectrum shared by a first operator and a second operator. The first wireless communication device and the second wireless communication device are associated with the first operator and a first cell. The first reservation request signal carries a request signature sequence associated with the first cell. The first wireless communication device communicates, with the second wireless communication device, data during the transmission period in the frequency spectrum shared by the first and second operators.

Abstract: Methods, systems, and devices are described for wireless communication. A transmitting device may send a signal including multiple transport blocks corresponding to multiple simultaneous hybrid automatic repeat request (HARQ) processes. Additional control information may be used to support the multiple simultaneous HARQ processes. For instance, the additional control information may indicate the number of available HARQ processes, an activity state for each HARQ process (e.g., active new data, active retransmission, or inactive), and the redundancy versions of each HARQ process. In some cases, the additional control information may be included in a downlink grant. A receiving device may respond with an acknowledgement or negative acknowledgment (ACK/NACK) for each of the transport blocks. The transmitting device may identify a retransmission status for each HARQ process based on the ACK/NACKs, and transmit new redundancy versions (or new data) to the receiving device.
