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. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARD) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive system information from a base station indicating at least one configuration rule for power control parameter setting for random access. The UE may measure one or more reference signals and may estimate a path loss of wireless communications between the base station and the UE based on the measured reference signals. The UE may select one or more parameters from one or more sets of parameters indicated in the configuration rule. The UE may select a first transmit power for a preamble of a random access message and a second transmit power for a payload of the random access message, based on the estimated path loss and the configuration rule for power control parameters and power ramping procedures. The UE may transmit the random access message according to the selected first and second transmit powers.

Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a first base station, a set of cross-link interference measurement configurations associated with location information, performing a cross-link interference measurement procedure on signals received based on the set of cross-link interference measurement configurations, or the location information, or a location of the first UE, or a combination thereof, and transmitting, to the first base station, a measurement value based on the performed cross-link interference measurement procedure.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) capable of supporting multiple antenna ports may determine that some combinations of antenna ports can be used simultaneously. The UE may make this determination by evaluating the relationships between the physical antennas and the transmit chains included in the UE. Upon determining that the combinations of antenna ports can be used simultaneously, the UE may send a message to a base station. The message may indicate whether two or more antenna ports can be used at the same time. The UE may communicate simultaneously over one or more antenna ports based on the scheduling information from the base station which takes into account the ability of the combination of antenna ports to be used concurrently.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may apply an open-loop multiple-input multiple-output (MIMO) scheme among a plurality of antenna groups associated with a plurality of antennas, wherein phase coherence cannot be maintained between the plurality of antenna groups; and may apply a closed-loop MIMO scheme among antennas within each antenna group of the plurality of antenna groups, wherein phase coherence can be maintained between antennas included in each antenna group of the plurality of antenna groups. Numerous other aspects are provided.

Abstract: Methods, systems, and devices are described for routing modification based on handover detection in UEs and network equipment. According to the principles of the present specification, communication between a User Equipment (UE) and a network equipment may be established over a first radio access technology (RAT) and a second RAT, and a coupling between the first RAT and the second RAT may be identified in the communication between the UE and the network equipment. A handover event associated with at least one of the RATs may be identified, and network traffic routing may be adapted based at least in part on the identified handover event and the coupling between the first RAT and the second RAT.

Abstract: Methods, systems, and devices for wireless communications are described that provide sequences of spreading codes and hopping patterns that may be used in non-orthogonal multiple access (NOMA) communications between a user equipment (UE) and a base station. A codebook of spreading codes and the associated hopping patterns may be systematically constructed by closed form formulas or look up table. The base station may receive multiple concurrent transmissions from multiple different UEs, and the sequences of spreading codes and hopping patterns, may be used to identify a particular UE of the multiple UEs.
