Abstract: One or more elements of a communication system receives a first indicator that a first wireless device is within a first coverage area of a first access node and is also within a second coverage area of a second access node. The first access node and the second access node are both configured to provide a multi-user multiple-input multiple-output (MU-MIMO) operating mode. The communication system determines a first number of wireless devices attached to the first access node that are utilizing the MU-MIMO operating mode. The communication system identifies the first wireless devices as being configured as a relay node. The communication system, based on the first number meeting a first threshold, instructs the first wireless device to attach to the second access node.

Abstract: There is provided support mechanisms for at least one adding and removing a cell from operation in a heterogeneous radio network having a first type of basic cell for providing basic radio coverage and a second type of cell associated to a basic cell as a capacity enhancing cell. A capacity enhancing cell is selectively switched on and off. When the capacity enhancing cell is shut down the cell does not exist over the air while cell configuration information is kept. When the capacity enhancing cell is switched on the cell becomes available again over the air interface. An indication of shut-down and a wake-up call message for switch-on of the capacity enhancing cell are communicated between a base station serving the capacity enhancing cell and a base station serving the basic cell. In this way energy savings can be supported without disrupting service availability.

Abstract: All or a portion of a timeslot of a slotted communication system may be dynamically designated for transmitting or for receiving. For example, a timeslot originally designated for receiving information at a wireless node may be temporarily designated for transmitting information from the wireless node. Such a designation may be made to accommodate a temporary asymmetry in traffic flow between wireless nodes or may be made based on other criteria. In some aspects, a resource utilization messaging scheme may be employed to mitigate interference associated with the designation of timeslots for transmitting or receiving.

Abstract: Disclosed embodiments provide techniques for computer networks infrastructure automatic convergence. The network devices are enabled to communicate with other adjacent network devices, independently of the device type, about detected changes that could affect them and together generate consensus utilizing a blockchain mechanism about the configuration changes that are accepted. A priority table specifies a priority for various device classes on a network. The devices, in response to a new network topology, determine if a new device configuration is necessary. When a new device configuration is necessary, data corresponding to the new device configuration is put into a blockchain block and appended to a network blockchain that is maintained by one or more nodes (devices) on the network. In this way, an immutable history of network configurations is maintained, improving network security and reliability.

Abstract: A joint low-band and high-band operation is disclosed for use in new radio (NR) shared spectrum (NR-SS) networks. In such networks, uplink and downlink communications may occur over separate bands, selected based on performance or quality characteristics. A user equipment (UE) may search each of one or both of a low-band spectrum and a high-band spectrum for system information signal that includes both a low-band random access configuration and a high-band random access configuration. The UE transmits a random access request on one of the bands and receives the random access response from one or more cells on the other band. The UE continues the random access procedure, transmitting the uplink message based on the random access response on the first band to a selected cell. The UE would then receive the contention resolution message from the selected cell on the second band.
