A wireless communication network serves user communication devices using Internet Protocol (IP) and Integrated Access and Backhaul (IAB). An IAB Mobile Termination (MT) and an IAB donor establish a wireless IAB link. The IAB MT and a Centralized Unit (CU) establish IP links over the wireless IAB link. The IP links have different QoS levels. The IAB MT exchanges data streams with the user communication devices. The data streams have different QoS requirements. The IAB MT and the CU correlate the QoS requirements of the data streams with the QoS levels of the IP links. The IAB MT and the CU exchange individual ones of the data streams over individual ones of the IP links based on the QoS correlations. The CU exchanges the data streams with a data communication network based on the QoS requirements.

Devices, systems, and methods for temporary link performance elevation are disclosed herein. In one embodiment, a link performance elevation (LPE) request is received. The LPE request is a request to temporarily boost performance of a network link between an endpoint and a service provider for a finite duration. Based on the LPE request, a temporary performance boost is activated for the network link at the start of the finite duration, and the temporary performance boost is deactivated for the network link at the end of the finite duration.

A cellular data communication network includes a BBU connected to a UPF by an IP network. A first translation module translates GFP packets into IP packets transmitted over the IP network. A second translation module translates the IP packets back into IP packets and forwards the IP packets to the UPF. A PFCP proxy intercepts control packets of the UPF. Information snooped by the PFCP proxy is provided to a routing/SDN controller that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF.

Wireless communications systems and methods related to stand-alone sidelink communication are provided. A first user equipment (UE) transmits a sidelink system information signal including an indication of a first preconfigured profile of a plurality of preconfigured profiles. The first UE communicates, with a second UE, a first sidelink transmission based at least in part on the first preconfigured profile.

A method of operating a mobile communications network including a plurality of base stations and a base station for a mobile communications network, wherein the base station includes a plurality of transmitters, a plurality of receivers and a processor, is disclosed. Each transmitter is configured to transmit radio signals to a plurality of mobile terminals. Each receiver is configured to receive radio signals from a plurality of mobile terminals. The processor is configured to serve a mobile terminal via the transmitter over multicast/broadcast across a radio link; receive information from the mobile terminal being served by the transmitter, in which the information derives from signal quality of a multicast/broadcast serving signal received at the mobile terminal from the transmitter; and provide to the mobile terminal first instructions based on a first comparison of the quality of the multicast/broadcast serving signal received at the mobile terminal. The comparison is based on a first threshold; in which the first instructions instruct the mobile terminal to switch to unicast; and in which the processor is further configured to vary the first threshold in dependence on a measure of loading of the network.

A communication device includes a receiver , a transmitter that executes first transmission processing and second transmission processing , and a controller that controls the transmitter in accordance with a radio quality of wireless communication so that either the first transmission processing or the second transmission processing is executed.

Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

A method performed by a base station in a wireless communication system is provided. The method includes transmitting, by a control plane (CP) of a centralized unit (CU) of the base station, a bearer context modification request message to a user plane (UP) of the CU of the base station, wherein the bearer context modification request message includes information associated with a request for a packet data convergence protocol (PDCP) sequence number (SN) status, and transmitting, by the UP of the CU of the base station, based on the bearer context modification request message, a bearer context modification response message to the CP of the CU of the base station, wherein the bearer context modification response message includes information associated with the PDCP SN status and information associated with at least one QoS flow, of which a service data adaptation protocol (SDAP) end marker is not received by the UP of the CU.

An aspect of the present disclosure relates to a computer-implemented method for routing a bursty data flow comprising a series of one or more data packets over a converged network comprising a plurality of communication networks, the method comprising, for each of the series of data packets in turn: selecting which one of the plurality of communication networks to transmit that data packet over by: (i) obtaining flow statistics indicating a current flow state of the bursty data flow; and (ii) selecting the one of the plurality of communication networks in dependence on said flow statistics; then initiating transmission of the data packet over that one of the plurality of communication networks. Further aspects relate to a data processing system, a computer program, a computer-readable data carrier and a data carrier signal.

A method for adjusting a total bandwidth for a network device is provided. The method includes: for every predetermined time period, determining a data rate of receiving data packets by the network device through a network communication during the predetermined time period; designating the greater one of the data rate and the total bandwidth as a maximal data rate; when a preset condition is not satisfied, using the maximal data rate as the total bandwidth; and when the preset condition is satisfied, determining an adjusted data rate that is smaller than the maximal data rate based on the maximal data rate, and using the adjusted data rate as the total bandwidth.
