A method for performing monitoring, commissioning, upgrading, analyzing, load balancing, remediating, and optimizing the operation, control, and maintenance of a plurality of remotely located RF signal repeater devices in a wireless network arranged to operate as an Internet of Things (IoT) network. Electronic RF signal repeater devices are employed as elements in the wireless network and communicate wireless radio frequency (RF) signals for a plurality of users. An RF signal repeater device may be arranged to operate as a donor unit device that provides RF signal communication between one or more remotely located wireless base stations, or other donor unit devices on the wireless network. Also, an RF signal repeater device may be arranged to operate as a service unit device that provides wireless RF signal communication between one or more user equipment devices (UEs) and a donor unit device or a wireless base station.

In one example, a communication device includes a LINK that generates a first output signal on a basis of a first external signal from a first external device, outputs the first output signal to a second external device, generates a second output signal on a basis of a second external signal from the second external device, and outputs the second output signal to the first external device, in which each of the first output signal and the second external signal includes command information indicating content of a command transmitted from the first external device, final-destination-device-identification-information for identifying a final destination device of data transmitted from the first external device, internal address information indicating an internal address of the final destination device, data length information indicating a length of the data transmitted from the first external device, and data-end-position-information indicating an end position of the data transmitted.

The disclosure provides systems, devices, and methods for distributed relay multiple-in multiple-out (DR-MIMO) communications. The system can have a master transmit node that transmits a message to a master receive node via one or more relay nodes. The relay nodes can each relay a portion of the message, performing a time or frequency shift along with the relay. The multiple relay nodes can function as a distributed antenna array for one or both of the master transmit node and the master receive node, forming a transmit group and/or a receive group. The transmit group and the receive group can thus provide MIMO capabilities to the master transmit node and the master receive node. The master transmit node can transmit multiple spatial streams through distributed relay nodes. The master receive node can receive multiple data streams from distributed relay nodes and perform MIMO detection.

A base station may determine different groups for a plurality of user equipments (UEs) participating in cooperative uplink transmission, and transmit mode configurations indicating whether or not UEs in each group are configured to transmit data as a data source or to relay data received from another UE configured to transmit data as a data source. A UE may participate, with one or more other UEs, in cooperative uplink transmission to the base station, wherein each UE belongs to a group. The UE may determine, for a transmission time interval (TTI), at least one operation to perform for the cooperative uplink transmission based, at least in part, on a group number of a group to which the UE belongs and an index of the TTI.

The one or more computing devices can be a default gateway for a plurality of user devices. In another aspect, the disclosed methods and systems can use a tag in routing a data block (e.g., service data) via a predefined route. For example, a device can transmit a request for a tag to a network node for routing a data block via a predefined route. Upon receiving the request, the network node can allocate a tag and create an interface. The interface can be associated with the tag and communications between the network node and the device for routing the data block.
