Sounding for radio-frequency (RF) sensing
This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitting device may transmit a sounding dataset, over a wireless channel, to a receiving device. The sounding dataset may include information carried in one or more training fields configured for channel estimation and sounding control information based, at least in part, on a configuration of the transmitting device. The receiving device may acquire channel state information (CSI) for the wireless channel based on the received sounding dataset and selectively generate a channel report for the wireless channel based, at least in part, on the CSI and the sounding control information. The channel report may indicate changes to the wireless channel which, in turn, may be used to sense objects in the vicinity of the transmitting device or the receiving device.
Multidrop network system and network device
A multidrop network system includes N network devices including a master device and a plurality of slave devices. The N network devices synchronize their respective time zones in a synchronization phase, then jointly perform equalizer coefficient training in a training phase, and then obtain their respective transmission opportunities in turn in a data transmission phase. Each network device includes a channel equalizer trained in the training phase and used for processing data in the data transmission phase. In the training phase, the master device sends out a training notification to request the slave devices to enter the training phase; the master device performs the equalizer coefficient training after it transmits the training notification, and the slave devices perform the equalizer coefficient training after they receive the training notification. After the completion of the equalizer coefficient training, the master device sends out a beacon to start the data transmission phase.
Default aperiodic channel state information reference signal beam for same numerology triggering
A UE receives DCI in a PDCCH, the DCI triggers reception of AP CSI-RS, and the PDCCH has a first numerology and the AP CSI-RS has a second numerology. The UE determines, when a CORESET is configured on an active BWP of a serving cell for receiving the AP CSI-RS and when the first numerology is the same as the second numerology, a default AP CSI-RS beam for receiving the AP CSI-RS based on a beam used for receiving the CORESET with a lowest ID in a latest monitored slot of the active BWP of the serving cell. The UE determines, otherwise when the first numerology is the same as the second numerology, the default AP CSI-RS beam for receiving the AP CSI-RS based on a QCL assumption of a PDSCH TCI state with a lowest ID on the active BWP of the serving cell for receiving the AP CSI-RS.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling comprising an indication of a format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE. The first UE may determine the channel state information for the sidelink channel between the first UE and the second UE. The first UE may configure a layer one uplink control message to indicate the channel state information report according to the format. The first UE may transmit, based at least in part on the format, the layer one uplink control message to a base station indicating the channel state information report.
