A multi-band network node has selectable backhaul/fronthaul configurations. Network nodes provide multi-band operation to take advantage of higher Internet speeds and to support lower latency (> 2 Gbps, < 4 ms latency) applications. A greater Wi-Fi device count (capacity) is supported by implementing communication over additional bands. Increased bandwidth is made available between connected nodes by selectively combining backhaul throughputs. Hardware quality-of-service (QoS) is provided by splitting traffic flows for low latency and data applications. Network coverage is extended by dynamic assignment of backhaul connections and by configuring unused backhauls as fronthauls.

Systems, devices, methods, and computer-readable storage media of channel switching. One device for channel switching includes a memory and at least one processor. The at least one processor is configured to communicatively couple with one or more client devices, using one of a primary bandwidth channel or a secondary bandwidth channel and transmit a first trigger on at least the primary bandwidth channel to at least a first client device of the one or more client devices based on at least one of (i) a bandwidth availability (ii) a quality of service parameter, or (iii) a secondary bandwidth switching capability, wherein the first client device switches from the primary bandwidth channel to the secondary bandwidth channel in response to the first trigger.

A data transmission method and apparatus. The method includes: a source access network device that receives an end marker from a core network device through a transmission tunnel of a PDU session of a first terminal device, where the PDU session is associated with a first multicast/broadcast service; and in response to the end marker, the source access network device determines, based on the association between the PDU session and the first multicast/broadcast service, that the end marker acts on the first multicast/broadcast service of the first terminal device, to stop sending data of the first multicast/broadcast service to a target access network device through a forwarding tunnel of the first terminal device.

A base station device includes: a storage that stores a group indicating unit data subject to retransmission out of predetermined number of unit data included in transmission data to be transmitted to a terminal device, and identification information to identify the group, in an associated manner; a receiver that receives, from the terminal device, identification information corresponding to transmission data transmitted to the terminal device; a communication controller that refers to the storage based on the received identification information, and that determines retransmission of unit data included in a group corresponding to the received identification information out of the transmission data; and a transmitter that transmits unit data included in the group determined to be retransmitted by the communication controller, to the terminal device.

This disclosure provides a time synchronization packet processing method and apparatus. The method includes: A terminal device receives first indication information, where the first indication information indicates the terminal device to enter an activation state of time synchronization for a first clock source, or the first indication information indicates the terminal device to enter a deactivation state of time synchronization; and processes a time synchronization packet of the first clock source based on the first indication information.

A device may include one or more processors configured to determine a first traffic identifier of a first wireless traffic stream, from a plurality of traffic identifiers. The one or more processors may be configured to generate a first frame including the first traffic identifier. The first frame may be to trigger a receiver device to send a response frame that includes quality of service (QoS) data corresponding to the first wireless traffic stream. The one or more processors may be configured to wirelessly transmit, via a transmitter, the generated first frame to the receiver device.

There is provided a method at a first network node, comprising: receiving, from a second network node, a message comprising a requested quality of service (QoS) profile and one or more alternative QoS profiles, wherein the QoS profiles are associated with a communication with a user equipment; determining that the requested QoS profile cannot be provided by the first network node for a communication between the first network node and the user equipment; determining that at least one of the one or more alternative QoS profiles can be provided by the first network node for a communication between the first network node and the user equipment; transmitting, to the second network node, an indication that an alternative QoS profile can be provided by the first network node; and, transmitting, to the second network node, an indication for configuring the user equipment based on the requested QoS profile.

A device, a system, and a method for transmissions during a restricted Target Wake Time (rTWT) Service Period (SP) are disclosed. In an embodiment, the device includes a wireless network interface device implemented on one or more integrated circuits (ICs), where the wireless network interface device is configured to transmit a beacon on a first link that indicates an rTWT SP for the first link, transmit a frame prior to a wake period of the rTWT SP, where the frame is transmitted during a first Transmission Opportunity (TXOP) that overlaps with the wake period, and transmit low latency traffic on the first link during the wake period, where the first TXOP that overlaps with the wake period is at least one of ended and continued.

A node of a wireless communication network receives first data indicating a desired quality of experience level for user data traffic of a user of the wireless communication network. Based on a control policy and the desired quality of experience level, the node determines a rule for controlling the user data traffic. Further, the node obtains second data indicating an estimated quality of experience level for the user data traffic subject to control according to the rule. Based on the first data and the second data, the node adapts the control policy, e.g., using a reinforcement learning, RL, mechanism.

In one embodiment, a device obtains information regarding temporary routing patches applied to a network. Each temporary routing patch implements a routing change in the network for a specified amount of time to avoid or mitigate against a service level agreement violation. The device evaluates, using the information regarding the temporary routing patches applied to the network, a plurality of replay scenarios for the network. The device determines, based on the plurality of replay scenarios, a long-term configuration change for the network. The device provides an indication of the long-term configuration change for display.
