Abstract: Systems, methods, and devices for wireless communication that support mechanisms for configuring an uplink relay for wireless powered IoT operations in a wireless communication system. A base station transmits a power signal to wireless powered IoT devices. The wireless powered IoT devices harvest energy from the power signal to power their reception/transmission circuitry. The base station transmits an information signal to trigger the wireless powered IoT devices to reflect a backscatter transmission. The wireless powered IoT devices transmit a backscatter transmission in response to receiving the information signal from the base station. The base station transmits configurations to a UE including configuration information respectively corresponding to the wireless powered IoT devices, and include information that the UE may use to detect the backscatter transmissions from the wireless powered IoT devices and relay them to the base station based on the configurations.

Abstract: Systems and methods for validating a control message for activation or deactivation of Semi-Persistent Channel State Information (SP-CSI) reporting in a wireless communication system are disclosed. In some embodiments, a method performed by a wireless device for validating a control message for activation or deactivation of SP-CSI reporting in a wireless communication system comprises receiving, from a network node, a control message for activation or deactivation of the SP-CSI reporting. The method further comprises making, based on the control message, a determination as to whether to activate the SP-CSI reporting or to deactivate the SP-CSI reporting and activating or deactivating the SP-CSI reporting in accordance with the determination. In this manner, the wireless device is enabled to distinguish between a control message activating SP-SCI reporting and a control message deactivating SP-SCI reporting.

Abstract: Disclosed are time synchronization methods for domains based on time information of a vehicle. A time synchronization method performed by a first end node belonging to a first domain of a vehicle includes: receiving a first frame including time information from the vehicle; changing the first end node to a grand master node of the first domain when the time information indicates a time of a universal time domain; and synchronizing a time of the grand master node with the time of the universal time domain.

Abstract: A method of transmitting, by a terminal of a wireless communication system, a message on a communication channel shared with other terminals. Before sending the message, the terminal listens on the communication channel until the terminal detects an absence of activity on the communication channel for an inactivity time ΔTin. When no activity is detected on the communication channel for the inactivity time ΔTin, the terminal waits for a waiting time ΔTat and then transmits the message on the communication channel. The waiting time ΔTat is identical for all of the terminals of the wireless communication system
