A wireless communication device includes a structural device interface (e.g., a USB interface) for connecting to a computing device and a wireless interface for making a wireless connection to a mobile device. The wireless communication device activates after being connected to the computing device and automatically executes a software application stored in memory of the wireless communication device. Subsequent to being connected to the computing device and executing the software application, the wireless communication device is configured to wirelessly discover the mobile device and wirelessly receive data from the mobile device over a wireless channel, for rendering the wirelessly received data at the computing device.

A portable communication device includes a USB interface that is connectable to and disconnectable from an external USB port of a computing device by a user for enabling Internet access service to the computing device. In an example application, the portable communication device may include a wireless communication component with baseband and radio components. Upon connecting the portable communication device to the external USB port of the computing device by the user, the portable communication device activates wireless Internet service with protected data stored in the portable communication device, and the computing device is thereby enabled with wireless mobile Internet access on the go. The portable communication device may further provide Internet sharing feature to other wireless devices over a local wireless communication link that may be compatible to a protocol within IEEE 802.11. The portable communication device may be configured as an adapter sized dongle.

An operating method, a sending method, and a related device. The operating method includes: sensing a first object, to obtain a first sensing result; and performing a first operation correlated with N windows according to the first sensing result, where N is a positive integer.

A first base station and a second base station, comprised in a wireless communication network, for managing a communication interface that is already set-up for communication between said base stations. The first base station determines to release said communication interface and sends, in response to the determination, a release message to the second base station. The release message commands the second base station to release the communication interface and comprises an indicator that indicates that it shall be avoided to attempt to again set up the communication interface and/or to set-up any further communication interface between the first base station and the second base station.

A method for sending beacon signals is provided. The beacon signals are to be received by a slave device to discover the master device for Device to Device communication. The master device receives information from a network node. The information informs about a set of available peer discovery resources to be used in a peer discovery frame by the master device for sending beacon signals. The beacon signals are detected by the slave device. The master device obtains a beacon transmission probability. At each specific peer discovery frame, the master device determines according to the beacon transmission probability, whether or not a beacon signal shall be transmitted during that specific peer discovery frame. When determining to transmit a beacon signal during that specific peer discovery frame, master device sends the beacon signal by choosing one of the peer discovery resources out of the received set of available peer discovery resources.

Interfacing according to a common public radio interface in a base station in a mobile communication system is described. The interfacing comprises a conversion process for rate-converting legacy data samples. First a predetermined number of the legacy data samples is converted to frequency samples in a frequency domain, then the frequency samples are zero padded to extend the frequency range according to a related sample rate of a 4G data format and then converted into a number of data samples of the related sample rate. The related sample rate is a multiplication of S/K times a basic frame rate of the 4G data format, S samples being allocated to K frames, K and S being integers and K being 8 or less. Advantageously large buffers for allocating a large number of legacy samples to 4G frames are avoided.

Embodiments herein relate to a method in a relay node (10) for acquiring information about a type of a radio network connection between a donor radio base station (12) and a radio base station (14). The relay node (10) and the donor radio base station (12) are comprised in a radio communications network and the donor radio base station (12) is serving the relay node (10). The relay node (10) receives a message from the donor radio base station (12), which message is indicating a type of radio network application protocol, which type is related to a type of the radio network connection between the donor radio base station (12) and the radio base station (14). The relay node (10) determines the type of the radio network connection based on the type of radio network application protocol indicated in the message. The relay node (10) also stores the type of radio network connection in relation to the radio base station (14) for selecting the type of radio network connection when later communicating with the radio base station (14).

A semiconductor chip includes a first wireless communication circuit, a local oscillator (LO) buffer, and an auxiliary path. The first wireless communication circuit has a signal path, wherein the signal path has a mixer input port and a signal node distinct from the mixer input port. The auxiliary path is used to electrically connect the LO buffer to the signal node of the signal path. The LO buffer is reused for a transmit (TX) function through the auxiliary path.
