In a mobile communication method by which a mobile station (UE) transmits a control signal to a radio base station (eNB) in an uplink by using an uplink dedicated resource, different methods for determining whether or not a synchronization state is established in the uplink, are used depending on whether or not the uplink dedicated resource is set up.

Mobile communication method and radio base station

Aspects of the subject disclosure may include, for example, receiving, by a feed point of a dielectric antenna, electromagnetic waves from a dielectric core coupled to the feed point without an electrical return path, where at least a portion of the dielectric antenna comprises a conductive surface, directing, by the feed point, the electromagnetic waves to a proximal portion of the dielectric antenna, and radiating, via an aperture of the dielectric antenna, a wireless signal responsive to the electromagnetic waves being received at the aperture. Other embodiments are disclosed.

Method and apparatus for coupling an antenna to a device

A distributed antenna and backhaul system provide network connectivity for a small cell deployment. Rather than building new structures, and installing additional fiber and cable, embodiments described herein disclose using high-bandwidth, millimeter-wave communications and existing power line infrastructure. Above ground backhaul connections via power lines and line-of-sight millimeter-wave band signals as well as underground backhaul connections via buried electrical conduits can provide connectivity to the distributed base stations. An overhead millimeter-wave system can also be used to provide backhaul connectivity. Modules can be placed onto existing infrastructure, such as streetlights and utility poles, and the modules can contain base stations and antennas to transmit the millimeter-waves to and from other modules.

Backhaul link for distributed antenna system

A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

Remote distributed antenna system

Embodiments describe registration in a wireless communication system. A method includes wirelessly transmitting over a WWAN a first registration message from a mobile device, wirelessly transmitting through the WWAN a second registration message to a WLAN access point and receiving at the mobile device access through the WLAN access point. According to another embodiment is a method for constructing a self-configuring ad-hoc network. The method can include receiving a GPS coordinate from a WWAN channel node at a management system and creating an initial topography based at least in part on the GPS coordinate to achieve a network connectivity with diverse routes between a plurality of nodes.

Methods and devices for interworking of wireless wide area networks and wireless local area networks or wireless personal area networks

A first radio station receives a message in a first frequency band from a second radio station and passes the message to a third radio station in a second frequency band, where the width of the first frequency band differs from the width of the second frequency band. The modulation of the data in the message is maintained unchanged and the first radio station is not required to perform decoding of the message.

Radio Communication with a Repeater

Approximating to a first straight line (G1), relay radiotelephone stations (R1-R4) are given uneven numbers regarding their position as messages are forwarded. A first radiotelephone station (AP) and relay radiotelephone stations with even numbers regarding their position during message-forwarding are set up to approximate a second straight line (G2) parallel to the first. An independent claim is also included for a radio communications system for carrying out the method of the present invention.

In A speed-dependent hand over procedure for hierarchic cell structures, a check is carried out given a mobile station traveling into A radio coverage domain of a micro cell to see whether the radio coverage of the mobile station with respect to the micro cell has significantly or insignificantly improved within a time interval. In case of a significant improvement, the micro cell is blocked for the rapidly traveling mobile station.

A method and arrangement for controlling a system of multiple traffic signals for regulating the traffic of vehicles is described. Traffic data is transmitted by wireless transmission to traffic data processing units assigned individually to a locally limited group of traffic signals, and each traffic data processing unit performs an analysis of the local traffic situation for the environment of the locally limited group of traffic signals up to, at the maximum, the neighboring locally limited groups of traffic signals.

Method and arrangement for controlling a system of multiple traffic signals

For transmitting voice between subscriber stations of a radio system, particularly a mobile radio telephone system, whereby an analog voice signal is digitally coded by voice frames (S), the voice frames (S) are first converted into voice-coded voice frames (S1). Subsequently, a plurality of these voice frames (S1) is combined to form a multi-voice frame (MSF1). These multi-voice frames (MSF1) are transmitted with error-protection. At the reception side, the multi-voice frames (MSF4) are in turn divided into voice-coded voice frames (S4) and, subsequently, the digital voice information contained in the transmitted voice frames is in turn converted into an analog voice signal.
