Abstract:
A data flow control method and communication device operable to communicate using a first radio access technology (RAT) and a second RAT are described. In a data flow control method, data flow congestion is detected. The congestion can be detected on a first communication link associated with the first RAT. The communication device can be controlled to enter a reduced power operating mode for communications via the first communication link. The entry of the reduced power mode can induce a base station supporting the second communication link associated with the second RAT to perform one or more data flow control operations. A data flow control method can include dropping data packets on a lower protocol layer to induce a higher protocol layer to perform a data flow control operation. The data flow control operation can induce the network to reduce data flow.

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The sensing method a first vehicle user equipment (UE) for collision avoidance in a wireless communication network comprises receiving a set of scheduling assignment (SA) information allocated to a set of second vehicle UEs, decoding the set of SA information, each of which includes SA information to each of the set of second vehicle UEs, performing energy sensing operation for resources to be used by each of the set of second vehicle UEs to determine additional potential SA transmission and data transmission from the set of second vehicle UEs over the resources, determining available resources for the data transmission from the first vehicle UE based on the performed energy sensing and SA sensing, skipping a channel sensing operation on at least one subframe that is used for the data transmission from the first vehicle UE, and transmitting data among resources identified as unused in next transmissions from second vehicle UEs.
Abstract:
Methods, systems, and apparatuses are described for adaptive dwell time for scan procedures. An access terminal (AT) may identify a scan period associated with performing a scan procedure on a first channel. The AT may analyze a channel congestion metric during the scan period and determine based, at least in part, on the channel congestion metric whether to exit the first channel. The AT may provide a probe request for transmission on a second channel during a remaining portion of the scan period based on the determination to exit the first channel.

Example implementations of the present disclosure are directed to systems and method for anticipatory video streaming for mobile users for congestion control in cellular networks. The example implementations involve a video streaming system and method as well as a scheduling algorithm to maintain Quality of Experience (QoE) at the video users.
Abstract:
A method and corresponding apparatus are provided for network configuration selection in a wireless network comprising a plurality of nodes. A subset of nodes of the plurality of nodes are configured to simultaneously participate in a sounding process, in which a node of the subset omni-directionally transmits a predetermined signal and in which other nodes of the subset of nodes sample the predetermined signal as received by an omni-directional antenna array of that node. Measurement reports are received from the subset of nodes, each measurement report comprising a signal source angle and a received signal strength. A path loss is determined in dependence on each measurement report to generate a set of path losses covering a plurality of transmitter node receiver node pairs. Then a directional configuration is selected for a directional antenna of each node of the subset of nodes to use in data transmission in dependence on the set of path losses.

Aspects of the disclosure are directed to congestion control in a user equipment in connected mode including upon receipt of a trigger, using a register to determine if a data packet transmission has been initiated by an application associated with the UE, wherein the UE is in a connected mode; retrieving an Application-specific Congestion control for Data Communication (ACDC) category mapped to the application associated with the UE, wherein a mapping between the ACDC category and the application is performed a priori to a transition to the connected mode; retrieving at least one access control parameter based on the ACDC category; and determining if the application is allowed to perform the data packet transmission based on the at least one access control parameter.
Abstract:
Technology for provisioning categories of applications on a mobile device is disclosed. A wireless network element can communicate Application Specific Congestion Control for Data Communications (ACDC)/Application and Service Access Control (ASAC) information to the mobile device. The ACDC/ASAC information can include a preconfigured list of application categories. Each application category can include a set of applications that are allowed to access a wireless network from the mobile device during at least one defined condition level. The wireless network element can activate ACDC/ASAC for one or more condition levels while a capacity threshold of the wireless network is exceeded. The wireless network element can allow a set of applications for a selected application category to communicate with the wireless network when the ACDC/ASAC is activated based on the one or more condition levels for the selected application category.

The proposed technology relates to methods and radio network nodes for Explicit Congestion Notification, ECN, marking of user traffic in wireless communication networks. For example, a method performed by a sending radionetwork node (10) comprises the step of monitoring (S10) a congestion metric on a data radio bearer, and the step of transmitting (S20) control information indicating traffic congestion on the same data radio bearer, based on the monitored congestion metric, to a receiving radio network node (20).Further, a method performed by a receiving radio network node (20) comprises the step of receiving (S100) control information indicating traffic congestion on a data radio bearer, based on a congestion metric, from a sending radio network node (10), and the step of marking (S200) next ECN-capable user packet of the user traffic on the same data radio bearer with ECN marking, based on the received control information.
