Abstract: The described technology is generally directed towards operating a user equipment node as a scheduler user equipment (e.g., which can be a local manager of other nodes in a group). The scheduler user equipment receives a scheduling request for the scheduling of the resources for transmission of data by a transmitter user equipment, and based on the traffic type requested, schedules the transmitter user equipment and receiver user equipment(s) with scheduling data / allocated radio resources. The transmitter user equipment can directly transmit to the receiver user equipment(s) on the allocated radio resources, e.g., without further involvement of the scheduler user equipment / local manager. For cellular data, the scheduler user equipment can schedule the transmitter user equipment to transmit to the scheduler user equipment as a receiver node.

Abstract: A closed loop carrier sense multiple access multiuser request to send and clear to send handshaking system is provided to efficiently allocate licensed and unlicensed spectrum for a plurality of mobile devices and across different base stations and mobile network operators. A user equipment device can be connected to a base station device via a first frequency in licensed spectrum, and a second frequency in unlicensed spectrum. The air interface on the first frequency can then be used to coordinate physical and virtual carrier sensing on a second frequency among a plurality of user equipment devices. Moreover, carrier sensing results from a plurality of UEs can be reported a base station device via the first frequency in licensed spectrum. The base station device can then schedule multiple user multiple input, multiple output (MU-MIMO) transmissions to a plurality of UEs on the second frequency in unlicensed spectrum.

Abstract: In a 5G network, an integrated access and backhaul (IAB) network can experience radio link failures or radio blockage conditions in mmWave frequency bands. Local IAB nodes that experience such conditions can make route changes in response to such situations to prevent packet loss or significant packet delay. Thus, in an IAB network, local IAB nodes can also utilize a routing function that monitors local conditions of IAB links to determine whether a change in route is required or not. Additionally, the local IAB nodes can receive external routing updates that can preempt a local IAB node routing function. Consequently, the IAB node can consider local routing preferences and external routing preferences prior to updating a routing table of the IAB node.

Abstract: The disclosed subject matter is directed towards scheduling and Hybrid Automatic Repeat Request (HARQ) operations by which nodes in a three party communication system can communicate. To schedule a data transmission from a transmitter node to receiver node(s), a local manager/scheduler node sends common downlink control information to the transmitter and receiver nodes. Via a scheduling request, the transmitting node can request the scheduling of the data transmission by the local manager node. The technology facilitates unicast and broadcast/multicast data transmissions; for a unicast data transmission, the scheduling request identifies the receiving node. The transmitting node can explicitly acknowledge reception of the downlink control information to the local manager node, or the local manager node can detect the data transmission, when it occurs, as an implicit acknowledgment that the common downlink control information was successfully received.

Abstract: To facilitate signal alignment for an integrated access backhaul (IAB) node, a system can determine a subset of beams that can be used for communication transmissions. Based on a signal quality associated with the subset of beams, the system can indicate that the subset of beams is to be used for the communication transmission. Consequently, the subset of the beams or another subset of the subset of the beams can be utilized for the communication transmission based on the signal quality of the beams.

Abstract: Integrate access and backhaul (IAB) nodes can multiplex access and backhaul links in time, frequency, or space, which includes the transmission of signals and/or channels utilized as part of initial access and measurements used for radio resource management (RRM). The same physical layer signals and channels used for these purposes by access a user equipment device can be reused for performing similar procedures at the IAB node. Consequently, the IAB node can leverage various muting patterns to employ the use of half-duplex and full-duplex synchronization signal block radio resource management such that mobile terminal functionality and distributed unit functionality of the IAB node can receive and transmit signals simultaneously.
