The method further comprises receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs. Thereafter, the AP broadcasts a multi-block acknowledgement M-BA frame, wherein the M-BA frame includes one or more pieces of association acknowledgement information and the association acknowledgement information is acknowledgement information of the association request message.
Abstract: Embodiments of this application provide a session management method, an interworking method between different systems, and a network apparatus. The session management method includes: when establishing a guaranteed bit rate (GBR) flow of a terminal device in a first communications system, determining, by a session management network element in the first communications system, that the GBR flow is a GBR flow required for handing over the terminal device from the first communications system to a second communications system; and establishing, by the session management network element for the GBR flow, a session context corresponding to the second communications system. The methods and the network apparatus are used to resolve a technical problem of resource waste existing in a handover method in the prior art.
Abstract: An apparatus for interfacing with a circuit switched network may be configured to detect when a data carrier signal from a circuit switched network is offline. While the data carrier signal from the circuit switched network is offline, the apparatus may send, to a network element coupled with the circuit switched network via the apparatus, control packets indicating that the data carrier signal is offline. The apparatus may further maintain an active data carrier signal between the apparatus and the network device by sending, to the network element, protocol idle frames. The apparatus may buffer, at the apparatus, packets sent from the network element to the circuit switched network. Once the data carrier signal is restored, the apparatus may send, to the circuit switched network, control packets indicating that the data carrier signal is online and the packet buffered at the apparatus while the data carrier signal is offline.

Abstract: Methods and apparatus for managing quality of service for video streaming, in which a Policy and Charging Rules Function (PCRF) in a Policy Charging Control (PCC) architecture of a telecommunications system receives from a Policy Control Enforcement Function (PCEF) a notification indicating that a video service has started for streaming video content to a user equipment (UE). A first Quality of Service (QoS) setting for streaming the video service to the UE is determined. First QoS setting data identifying the first QoS setting is transmitted to the PCEF. The PCEF transmits a further notification to the PCRF indicating that a particular stage has been reached. The PCRF receives the notification from the PCEF. In response to the further notification, a second QoS setting specifying a lower QoS than the first QoS setting for streaming the video service after the particular stage is determined. The PCRF identifies the second QoS setting to the PCEF.

Abstract: A method for time-slotted scheduling of packets in timeslots between N nodes and K>1 access points in an industrial wireless network, performed by a network controller of the industrial wireless network. The method includes determining the time-slotted scheduling by allocating each timeslot to a respective one of the nodes, wherein each timeslot for each node is divided in K sub-slots, one for each access point, such that in sub-slot k of each timeslot, where 1?k?K, transmission or reception of a packet is made between access point k and the node to which that timeslot is allocated. The method includes providing information to the access points about the determined time-slotted scheduling.

Abstract: The disclosure relates to method and system for transmitting a data packet in downlink in frequency division duplex (FDD) communication mode employing adaptive asynchronous Hybrid Automatic Repeat Request (HARQ) mode. The method includes receiving a current Channel Quality Indicator (CQI) from a user transceiver. The CQI is reported by the user transceiver at a periodic interval based on a radio frequency channel condition. The method further includes evaluating a degradation in the radio frequency channel condition based on a decrease in the current CQI with respect to a previously reported CQI. The method further includes retransmitting at least one of a set of transmitted data packets stored in a HARQ retransmission buffer to the user transceiver, based on the degradation in the radio frequency channel condition and without waiting for a corresponding HARQ negative acknowledgement (NACK) signal from the user transceiver.
Abstract: A method for performing mobility-measurements in new radio (NR) based 3GPP mobile communication network is provided. The method includes receiving network information with respect to a geographical area from one or more user equipments (UEs) operating in geographical area for a predefined duration of time. The received network information is classified at various time-instants during the predefined duration of time as at least one of an NR spectrum availability and NR spectrum non-availability. An overall probability of availability of the NR spectrum within the area is calculated for a time-instant subsequent to the predefined duration of time based on the classified network information. The UE is enabled for scheduling NR measurements within the area based on the calculated probability.
Abstract: A system and method for efficient collection and distribution of mission-critical information (MCI) throughout a multi-node communication network is disclosed. In embodiments, the multi-node communication network may include a clusterhead node including a communication interface and a controller. In embodiments, the controller transmits an MCI request packet to neighbor nodes of its cluster. The controller receives MCI report packets from the neighbor nodes (or a subset thereof) throughout a first time interval. The controller rebroadcasts the MCI request packet to the neighbor nodes through increasingly shorter time intervals as MCI report packets continue to be transmitted in response. When the controller determines that no MCI report packets have been transmitted during the most recent time interval, the controller generates and transmits an MCI publish packet including the MCI information collected from each neighbor node.

Abstract: Embodiments herein describe mirroring slices in a 5G domain (or network) in a Wi-Fi domain (or network). A slice in a 5G domain allows a service provider to establish a separate network within the 5G network which can have a different minimum bandwidth, minimum latency, a quality of service (QoS) level, a certain application must be proximate to the client devices, and a service level agreement (SLA) relative to the other slices. The embodiments herein can mirror the traffic isolation and flexibility of 5G slices in a Wi-Fi network by using resource units (RUs). The AP can assign RUs in a manner to match the bandwidth and latency of the corresponding 5G slice. Further, the AP controls which client devices can use the RUs and can ensure that only the client devices that can use the same 5G slice can use the same RUs.
