According to some embodiments, a method of operation of a transmit node in a wireless communication system comprises performing polar encoding of a set of K information bits to thereby generate a set of polar-encoded information bits. The K information bits are mapped to the first K bit locations in an information sequence SN. The information sequence SN is a ranked sequence of N information bit locations among a plurality of input bits for the polar encoding where N is equivalent to a code length. A size of the information sequence SN is greater than or equal to K. The information sequence SN is optimized for the specific value of the code length (N). The method may further comprise transmitting the set of polar-encoded information bits.

Methods and apparatuses for sending and receiving CSI reports are disclosed. A method, comprising: receiving triggering information for N aperiodic Channel Suite Information (CSI) reports and the CSI reference signal (CSI-RS) resources linked with the N CSI reports, wherein N is an integer greater than 1; determining M CSI reports and calculating M CSIs each indicated by a determined CSI report according to the CSI-RS resources linked with the determined M CSI reports, wherein M is an integer than is less than N; and sending M CSI reports each indicating a calculated CSI.

A transmitter may be configured to determine a coding rate at which to encode data packets based on a quantity of encoded packets used by a receiver for recovery of one data packet. The transmitter may be further configured to transmit a set of encoded packets generated at the coding rate to the receiver. The receiver may be configured to receive, from the transmitter, encoded packets carrying a set of data packets encoded at a coding rate. The receiver may be further configured to transmit, to the transmitter, feedback indicating a quantity of a set of the encoded packets used for recovery of one data packet of the set of data packets. The receiver may be further configured to receive, from the transmitter, other encoded packets carrying another set of data packets encoded at another coding rate.

Systems and methods to transmit data over multiple communication channels in parallel with forward error correction. Original packets are evenly distributed to the channels as the initial systematically channel-encoded packets. Subsequent channel-encoded packets are configured to be linearly independent of their base sets of channel-encoded packets, where a base set for a subsequent channel-encoded packet includes those scheduled to be transmitted before the subsequent packet in the same channel as the subsequent packet, and optionally one or more initial packets from other channels. The compositions of the sequences of the encoded packets can be predetermined without the content of the packets; and the channel-encoded packets can be generated from the original packets on-the-fly by the transmitters of the channels during transmission. When a sufficient number of packets have been received via the channels, a recipient may terminate their transmissions.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for training and deploying machine-learned communication over radio frequency (RF) channels. One method includes: determining an encoder and a decoder, at least one of which is configured to implement an encoding or decoding that is based on at least one of an encoder machine-learning network or a decoder machine-learning network that has been trained to encode or decode information over a communication channel; determining first information; using the encoder to process the first information and generate a first RF signal; transmitting, by at least one transmitter, the first RF signal through the communication channel; receiving, by at least one receiver, a second RF signal that represents the first RF signal altered by transmission through the communication channel; and using the decoder to process the second RF signal and generate second information as a reconstruction of the first information.

An automatic gain control method, sensor (700), and radio device (900); by means of using the saturation information of a test echo unit to adjust the gain coefficient of a transmitting and receiving link, it is ensured that the received signal power used for target detection is located within a rated threshold range, further improving the accuracy of sensor (700) target detection, and avoiding defects such as missed detection, false detection, and even blindness.

A network management system manages the operation of a home security system in a communication network, such as a mesh network. The home security system can include multiple components such as a camera, a lighting device, a security alarm, a doorbell switch and doorbell chime, and a fingerprint sensor, which connect with the communication network to perform various operations. The network management system monitors environmental parameters of the communication network, such as parameters associated with the access points and components of the home security system, determines an access point to which a component of the home security system is to be connected for efficient operation of the home security system, and connects the component to the communication network via the determined access point.

Use of multiple sensors to determine whether motion of an object is occurring in an area is described. In one aspect, an infrared (IR) sensor can be supplemented with a radar sensor to determine whether the determined motion of an object is not a false positive.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication associated with phase noise characteristics of the UE. The UE may receive an indication of pilot allocation sizes, for different data modulation and coding schemes (MCSs) for communications, of frequency-domain contiguous pilots for phase noise mitigation based at least in part on the indication associated with the phase noise characteristics of the UE. Numerous other aspects are described.

The present application relates to a paging mechanism. In an example, a network can transmit SSBs periodically on multiple SSB beams. A UE can receive, during a DRX cycle, an SSB per detected SSB beam and perform SSB-based measurements. Based on these measurements, the UE can perform PDCCH monitoring and PDSCH decoding on at least two beams. The PDCCH monitoring can indicate a scheduled paging message from the network. The PDSCH decoding can allow the UE to determine the paging message.
