CONTENT TRANSMISSION METHOD AND APPARATUS USING TERMINAL STORAGE DEVICE IN WIRELESS COMMUNICATION SYSTEM

This disclosure relates to the 5th generation (5G) or pre-5G communication system for supporting a higher data rate after the 4th generation (4G) communication system such as Long Term Evolution (LTE). The method for operating the core network in a wireless communication system according to this disclosure comprises the processes of determining the content to store in the terminal based on the location information of the terminal, transmitting the content transmission command to the base station so as to transmit the content to the terminal in response to the determination, checking whether the terminal has entered the overload cell, and forming a D2D communication link between the terminal and another adjacent terminal when it is identified that the terminal has entered the overload cell.

5G congestion control

A split radio access architecture comprises a packet processing node and one or more baseband processing nodes. The packet processing node receives, from a baseband processing node, first feedback corresponding to air interface congestion between the baseband processing node and a wireless device receiving packets from the baseband processing node. The packet processing node also receives, from the baseband processing node, second feedback corresponding to transport network congestion of a transport interface between the packet processing node and the baseband processing node. The packet processing node transmits user data to the baseband processing node based on the received first and second feedback.

20230044660 · 2023-02-09 · ·

The present disclosure describes methods, system, and devices for selecting a radio bearer mode for multicast broadcast services (MBS). The method includes informing a radio access network (RAN) that a user equipment (UE) is receiving/interested to receive or no longer receiving/interested to receive multicast broadcast service (MBS) services via a cast mode. The method includes sending, by the UE, MBS interest information to the RAN, the MBS interest information comprising a list of MBS services of interest.

Deferred download based on network congestion

Manners of scheduling downloads for a user equipment (UE). The UE is configured to establish a connection to a network and receive an indication of a user-initiated download, determining whether the download is to be performed now or at a subsequent time, when the download is to be performed at the subsequent time, determine a time window during which the download is to be initiated and initiate the download during the time window.

Method for utilization-based traffic throttling in a wireless mesh network

A system and method for managing congestion in a multi-hop wireless network, employing congestion notification messages. The technology has three main components: a mechanism at the Medium Access (MAC) layer for determining when a given source or transit node is deemed congested; a mechanism at the Network Layer (NL) determining how to propagate this information to applications, including suitably combining overload indications received from neighbors; and a mechanism at the Transport Layer (TL) of each source of traffic for determining when a source is generating excessive traffic, and combining it with Medium Access Control (MAC)-based overload indication from downstream nodes, thus providing a multi-layer approach to traffic throttling.

ADAPTIVE TRIGGERING OF RTT RANGING FOR ENHANCED POSITION ACCURACY

A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.

MOBILITY MANAGEMENT SWITCHING CENTER, COMMUNICATION SYSTEM, AND COMMUNICATION CONTROL METHOD

A mobility management switching center is for communicating with user equipment of a communication system that supports LTE or 3G, the mobility management switching center including a receiver that receives a session management signal from the user equipment; and a transmitter that transmits, when the session management signal is received, a restriction signal for instructing not to transmit a new session management signal to the user equipment.

Methods, systems, and devices for wireless communications are described. In some cases, an application enabler layer (e.g., a vehicle-to-everything (V2X) application enabler (VAE) layer), may identify a congestion control configuration that includes capabilities for collecting operation information. The application enabler layer may receive, from a set of user equipment (UEs), the operation information in accordance with the capabilities. Then, the application enabler layer may generate congestion control instructions for one or more UEs of the set of UEs based on the received operation information. Additionally or alternatively, an application enabler architecture layer (e.g., a service enabler architecture layer for verticals (SEAL)) may identify a congestion control configuration including capabilities for collecting operation information and monitor sidelink performance for the set of UEs in accordance with the capabilities. The application enabler architecture layer may identify a congestion status for a communication type based on monitoring the sidelink performance.
