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.

The present invention relates to the transmission of traffic in a mobile communication system and, more particularly, to a method and device for transmitting traffic in consideration of a quality of service (QoS) characteristic of the traffic. The purpose of the present invention is to efficiently provide a QoS differentiated according to traffic in consideration of a traffic type and a content provider in a network congestion situation of the mobile communication system.

The present disclosure is to effectively perform coordinated transmission in a wireless communication system. A base station includes a controller for providing control to generate control information including channel state information and buffer occupancy state related information of terminals, and a communication unit for transmitting the control information. In addition, the present disclosure also includes other exemplary embodiments different from the aforementioned exemplary embodiments.

The present disclosure relates to a load balancing for a control in a wireless communication system. According to a various embodiments of the present disclosure, a method for operating a base station in a wireless communication system comprises determining a mobility of a terminal, and responsive to the mobility exceeding a threshold, transmitting, to the terminal, a message for requesting the terminal to process a control plane of the terminal with at least one other base station.

Embodiments of the present invention provide a service processing method, a related apparatus, and a system. The method includes: UE adds a service type indication of a service initiated by the UE to an RRC connection request and sends the RRC connection request to a base station, and adds the service type indication of the service initiated by the UE to a non-access stratum NAS request and sends the NAS request to a mobility management network element. In this way, when a network side performs congestion control or overload control, the base station may determine, according to the service type indication, that the service initiated by the UE is a voice service, a video service, or a short message service, accept the RRC connection request. Similarly, the mobility management network element may accept, according to the service type indication, the NAS request.

A user equipment (UE) may transmit a sounding reference signal (SRS) on a component carrier (CC) that is otherwise configured for downlink communications. Due to a carrier aggregation configuration or UE capability, the UE may need to retune certain components to transmit on the CC. If the SRS transmission, including the retuning time, collides with another transmission (e.g., in uplink or downlink) the UE may drop the SRS, drop the other transmission, or puncture the other transmission to facilitate the SRS transmission. The determination about a collision may depend on the retuning time, channel, or type of control information in the other transmission. In some cases, a UE may drop the other transmission if transmitting the SRS would prevent the UE from transmitting a demodulation reference signal, hybrid automatic repeat request (HARD) feedback. In some cases, the determination may be based upon a prioritization and may also depend on a subsequent subframe.

An in-flight entertainment and communications (IFEC) system is configured to interconnect an avionics data bus to a local area network. An avionics interface is connectable to the avionics data bus, and receptive to avionics data transmitted on the avionics data bus by one or more avionics nodes over a predetermined protocol. A local network interface establishes the local area network, and portable electronic devices may be connectable to the local network interface over the local area network to establish a data communications link thereon. A data processor is connected to the avionics interface and the local network interface, and relays the avionics data from the avionics interface to the local network interface for transmission to the one or more portable electronics devices. This transmission is according to the predetermined protocol over the data communications link established on the local area network.

A mobile communication system includes a control device and a base station device. Data communication between the control device and the base station device is conducted using a fixed-length data size and a variable-length data size. The control device transmits information indicating whether a data size of the data communication has a fixed length or a variable length. The base station device receives the information from the control device.

Disclosed herein is an architecture for a Digital Capacity Centric Distributed Antenna System (DCC-DAS) that dynamically manages and distributes resources in different locations where there is demand for capacity. The DCC-DAS also allows for the routing of resources to other applications such as location finding devices, jamming devices, repeaters, etc.
