Disclosed are systems and methods for a self-contained multi-modal communication system. The multi-modal communication system comprises a first mobile telecommunication node, which provides a private telecommunication network, a layer 2 (L2) backhaul wireless transceiver, an ethernet switch and an embedded edge cloud compute device. The edge cloud compute device includes an automatic failover detection system, wherein the automatic failover detection system receives as input a plurality of network parameters and automatically performs failover and communication modality switching for one or more communication devices associated with the self-contained multi-modal communication system.

A first device having a transceiver and an antenna operatively connected to the transceiver and a second device having a transceiver and an antenna operatively connected to the transceiver, the first device in operative communication with the first device through a communications linkage separate from the transceiver of the first device and the transceiver of the second device. The first device is adapted to wirelessly communicate with a remote device through the transceiver of the first device. The second device is adapted to wirelessly communicate with the remote device through the transceiver of the second device. The system is configured to evaluate the wireless connection between the first device and the remote device and to evaluate the wireless communication between the second device and the remote device and determine whether the first device or the second device has a better connection.

A base station belonging to a first cell group (CG) that includes a transceiver configured to connect to a user equipment (UE) and a processor configured to transmit a command to the UE to perform a BWP switch, and monitor a physical uplink control channel (PUCCH) for an acknowledgement or a negative acknowledgement (ACK/NACK) for a predetermined period of time, wherein the predetermined period of time is the sum of a standard-defined period of time between transmission of a radio resource control (RRC) command and receipt of the ACK/NACK, a time to process an RRC command, and a time to perform a BWP switch.

A network device sends first radio resource control (RRC) reconfiguration signaling to a terminal device, where the first RRC reconfiguration signaling carries a first configuration, and the first RRC reconfiguration signaling indicates the terminal device to make the first configuration effective or make the first configuration ineffective. The network device receives first RRC reconfiguration complete signaling sent by the terminal device, where the first RRC reconfiguration complete signaling indicates that the first configuration has been effective or the first configuration has been ineffective.

A first base station may communicate with a second base station regarding a wireless device and handover. The communication may involve indicating carriers associated with the wireless device. The carriers may be of different types, and may have differences regarding reference signals. The first base station may cause a handover of the wireless device from the first base station to the second base station.

Certain aspects of the present disclosure provide techniques for efficient signaling of frequency resources in multiple cells. For example, a single downlink control information (DCI) transmission to a user equipment (UE) may be used to indicate a bandwidth part (BWP) switch to be applied in multiple cells. In some cases, the BWP switch may be into a pre-defined BWP across the multiple cells (and the same DCI may also schedule or trigger data or reference signals in the pre-defined BWP).

Embodiments of the present disclosure provide methods and apparatus for configuring channel resource. A method performed at a network node may comprise: determining (S101) a need to change radio frequency of a cell served by the network node; determining (S102) whether a configuration for channel resource to which the radio frequency to be changed has been received by a terminal device served in the cell; and transmitting (S103), to the terminal device, an indicator for the configuration for the channel resource, in response to that the configuration for the channel resource has been received by the terminal device. According to embodiments of the present disclosure, the network node may just transmit an indicator for the configuration for the channel resource, and thus the messages in the communication network needed to configure channel resource may be reduced.
