An apparatus configured to broadcast a wireless signal when a processing circuitry of the apparatus is in a non-active state. The broadcasted signals can be used to localize the apparatus when the apparatus is lost. The apparatus has a first processing circuitry configured to operate in an active power consuming mode and a non-active low power consuming mode. The apparatus further has a wireless transmit circuitry configured to be in an active mode and broadcast a wireless signal when the first processing circuitry switches operation mode from the active mode to the non-active mode. The first processing circuitry is powered by a battery supply, and the first processing circuitry may be configured to automatically switch from the active mode to the non-active mode when the supply voltage provided by the battery supply decreases below a threshold voltage, whereby the wireless circuitry will be broadcasting.

A method is provided of managing a non-static collection of machines. A first client machine runs a first communication protocol. The non-static collection of machines includes a first linear communication orbit, the first linear communication orbit comprising a sequence of machines that run the first communication protocol, and a second linear communication orbit, the second linear communication orbit comprising a sequence of machines that run a second communication protocol distinct from the first communication protocol. The first client machine receives an instruction from a server to install the second communication protocol, installs the second communication protocol, and then submits a registration request to the server. The first client machine receives, from the server, contact information of a list of potential neighbors. The first client machine then, proactively constructs and maintains a respective local segment of the second linear communication orbit.

A method and apparatus for supporting a device-to-device (D2D) communication between user equipments (UEs) are provided. The method of a device-to-device (D2D) communication between user equipments (UEs), the method includes: receiving, at a transmission (Tx) UE, resource assignment information transmitted from an evolved NodeB (eNB), the resource assignment information being associated with a D2D discovery signal to be transmitted in a discovery period; determining, at the Tx UE, that a D2D discovery signal associated with a first discovery type and a D2D discovery signal associated with a second discovery type are to be transmitted in a first subframe included in the discovery period; and in the first subframe, transmitting the D2D discovery signal associated with the second discovery type and dropping the D2D discovery signal associated with the first discovery type.

Methods, systems, and devices for wireless communications are described. In a first case, a first user equipment (UE) may transmit to a second UE a sidelink discovery message preamble corresponding to a sidelink discovery message. The first UE may identify resources for transmission of the sidelink discovery messages based on the sidelink discovery message preamble. The first UE may either transmit the sidelink discovery message to the second UE or may receive the sidelink discovery message from the second UE using the identified resources for the transmission of the sidelink discovery message. In some cases, the second UE may transmit sidelink control information (SCI) to the first UE, and may transmit a sidelink discovery message to the first UE based on resources identified in the SCI. In some cases, the first UE may transmit the sidelink discovery message without transmission of a preamble or a SCI.

Some demonstrative embodiments include apparatuses, systems and/or methods of Neighbor Awareness Networking (NAN) Geo-Fencing. For example, an apparatus may include circuitry configured to cause a Neighbor Awareness Networking (NAN) device to process a plurality of geo-fencing parameters of a geofence from an application on the NAN device; and perform geo-fencing with another NAN device based on the geo-fencing parameters.

The transmission method of a discovery signal includes: determining one or more transmission resources from resource pools according to a sidelink discovery signal needing to be transmitted; and transmitting the sidelink discovery signal by using the one or more transmission resources; wherein the resource pools are segmented in a frequency domain and/or a time domain and hence comprise multiple types. Hence, cases of waste of resources or of impossible carrying may be reduced as much as possible even if sizes of discovery information are different due to different scenarios.
