Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: Aspects of the disclosure relate to determining channel state information (CSI) on a component carrier. In an example operation, a device determines a mapping between first time-frequency resources corresponding to a first component carrier (CC) and second time-frequency resources corresponding to a second CC using a prediction algorithm. The device receives, from a base station, a channel state information reference signal (CSI-RS) on the first time-frequency resources corresponding to the first CC and measures first CSI on the first time-frequency resources corresponding to the first CC based on the received CSI-RS. The device further predicts second CSI on the second time-frequency resources corresponding to the second CC based on the measured first CSI using the prediction algorithm. The device then generates a CSI report based on the predicted second CSI and sends the CSI report to the base station.

Abstract: A method of wireless communication, executed by a user equipment (UE), receives, from a base station, a broadcast or multicast message including a known payload, as well as a configuration for the known payload. The method also trains an artificial neural network with the known payload. A method of wireless communication, executed by a base station, configures a known payload for multiple UEs and signals, to the UEs, an indication of which physical channel will include the known payload, as well as time/frequency resources of the known payload. The method also broadcasts or multicasts the known payload to facilitate neural network training at the UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, an indication of a resource allocation for a data communication having a known payload, the known payload comprising data associated with a machine learning process; and communicate with the base station based at least in part on the resource allocation. Numerous other aspects are provided.

Abstract: Apparatuses and methods of beam switching are presented. A beam switch message (BSM) is transmitted to a second device via a first beam set. The BSM includes a command to switch from communication via the first beam set to communication via a second beam set at a switch time. A response message is received from the second device via the first beam set. The response message indicates that the second device received the BSM. A communication is sent to the second device via the second beam set after the switch time if the response message is received.

Abstract: Apparatuses and methods of beam switching are presented. A first beam switch message (BSM) is transmitted to a second device, the first BSM including a first instruction for switching beams. A reset state is selected from a plurality of reset states including a first state for the second device to disregard the first instruction and a second state for the second device to maintain execution of the first instruction. A second BSM is transmitted to the second device before the second device completes execution of the first instruction. The second BSM includes a second instruction for switching beams and indicating which reset state is selected.

For example, the method may include transmitting a first data packet from the small cell base station to a network entity, receiving a second data packet from the network entity in response to the transmission, calculating a time delay between the transmitting of the first data packet and the receiving of the second data packet, and determining whether or not a backhaul of the small cell base station is congested based on the calculated time delay. As such, light active estimation mechanism for backhaul management at a small cell base station may be achieved.
