摘要:
Various systems and methods for providing identifiers for proximity services are described herein. A proximity server to provide identifiers for proximity services comprises: a receiving module to receive from a requester user equipment (UE) at a proximity services server, a request to connect the requester UE to a connection UE, the request including a user-defined proximity identifier that identifies the connection UE; a permission module to confirm permission for the requester UE to connect to the connection UE; and an output module to, based on the confirmation, provide a first link layer identifier (LLID) to the connection UE for use in direct discovery between the requester UE and the connection UE.

In various embodiments, two wireless communication devices may communicate with each other using multiple protocols, by dividing the data to be communicated into multiple portions, and using each protocol to communicate different portions. The different protocols may be used simultaneously or concurrently. This multi-protocol technique may be used in several different ways to provide different types of advantages in wireless communications.

A method for a wireless communication network is presented. In one embodiment, the method includes receiving, by a base station, information about one or more interfering base stations with respect to a communication channel used by a mobile station. The method includes sending silence requests to an interfering base station to reduce interference from that interfering base station with respect to the communication channel. The method further includes establishing communication with the mobile station via the communication channel.

Briefly, in accordance with one or more embodiments, a mechanism disclosed herein groups transmissions to machine-to-machine (M2M) devices in the downlink which can significantly reduce the overhead of transmission. One or more bursts to be transmitted in the downlink to one or more respective devices are aggregated and concatenated into a concatenated burst comprising one or more sub-bursts corresponding to the one or more bursts. The concatenated burst is encoded as a single payload to be transmitted, and the payload is transmitted to the one or more devices such that the devices are capable of decoding their respective sub-bursts in the concatenated burst.

A station grouping mechanism has been presented for a wireless device that collects Multi-hop Relay Base Station (MR-BS) and Relay Stations (RSs) into groups according to their locations in a tree topology and assigns them with a phase. Grouping or partitioning MR-BS and RSs and assigning a distinct phase to the group prevent the MR-BS and the RSs from transmitting and receiving at the same time.

FCH locations are mapped to preamble sequence sets to allow more than three stations to transmit their FCHs with minimized or reduced interference. A lower interference environment may be provided to transmit the FCH within each DL relay phase when the number of stations within the phase is less than the number (L) of distinct FCH locations. With more than L stations in a DL relay phase, a reduced interference environment for FCH transmission may be achieved by assigning the same FCH location to RSs that are far away from each other.

Certain embodiments herein are directed to managing wireless spectrum, which may include recommending or transmitting spectrum usage changes to one or more wireless devices. A spectrum management system comprising one or more computers may receive spectrum usage information associated with one or more wireless devices. The spectrum management system may generate a spectrum usage map based on the received information. Based on the spectrum usage map, a spectrum usage change is determined and transmitted to one or more wireless devices. The wireless devices may change their operation in accordance with the spectrum usage change.

Generally, this disclosure provides systems, devices, methods and computer readable media for context based spectrum management. A device may include a user preference determination module to determine a level-of-service preference of a user of the device, the preference associated with an application. The device may also include a user state determination module, to determine a state of the user, and a device capability determination module, to determine capabilities of the device. The device may further include an application programming interface (API) to provide the context to a cloud-based server configured to manage spectrum. The context includes the preference, the state and the capabilities. The API is further configured to receive content delivery options from the cloud-based server.
摘要:
Device-to-device (D2D) contention management systems and methods provide managed offloading of cellular network traffic through a contention-based network. For each link in a group of links between nodes in the contention-based network, a link cost is calculated to determine a number of potential links that may interfere with the link, if activated. Each link is evaluated in the order of ascending link cost to determine whether it complies with predefined conditions and whether activating the link increases or decreases D2D network throughput. If the link increases throughput, the link is activated.
摘要:
Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for opportunistically transitioning service flows of mobile devices between being direct and indirect. In various embodiments, a proximity between first and second mobile devices that are in wireless communication with each other may be monitored. In various embodiments, a selective transition of a service flow between the first and second mobile devices from being indirect through the radio network access node using a first radio access technology (“RAT”) to being direct using a second RAT may be facilitated, e.g., responsive to a determination that a first criterion has been met. In various embodiments, a selective transition of the service flow from being direct using the second RAT to being indirect using the first RAT may be facilitated, e.g., responsive to a determination that a second criterion has been met.
