Abstract: To find a D2D channel, by example a shared channel for offload traffic from an allocated D2D channel, a cellular network access node sends a configuration message with parameters (e.g., sensing time, frequency band, sensing mechanism, cyclic shift) for a D2D device to sense spectrum. From results of this spectrum sensing is decided whether to utilize a frequency band, sensed according to the parameters, for D2D communications. In an embodiment the network selects a subframe configuration to set the sensing time, in which different subframe configurations have different-length guard periods which is the sensing time. In embodiments a first sensing is within a guard period and represents coarse sensing results and if those are not sufficient the network configures a longer sensing time (e.g., spanning multiple subframes) for finer sensing results. The network or alternatively the D2D device decides whether to use the sensed frequency band for offload traffic.

Abstract: Provided is a system and method for performing a ranging process in a communication system. If a Subscriber Station (SS) detects the insufficiency of UpLink (UL) resources for transmission of a Ranging Request (RNG_REQ) message during the ranging process, it transmits a UL resource allocation request message requesting additional allocation of the UL resources to a Base Station (BS) for additional transmission of the RNG_REQ message to cause the BS to additionally allocate the UL resources for the additional transmission of the RNG_REQ message.

Abstract: A communications terminal communicates data to and from a mobile communications network. The mobile communications network includes a radio network part including one or more base stations configured to provide a low bandwidth communications interface formed from a low bandwidth carrier for communicating the data to or receiving the data from the communications terminal in accordance with a relatively low bandwidth, and to provide a high bandwidth communications interface formed from a high bandwidth carrier for communicating the data to or receiving the data from the communications terminal in accordance with a relatively high bandwidth. The communications terminal is configured to attach for communication to the high bandwidth interface, and in response to receiving a command from the mobile communications network, to detach from the high bandwidth interface and to re-attach to the low bandwidth interface for communicating the data to or from the mobile communications network via the low bandwidth interface. Accordingly communications resources of the mobile communications network which are allocated for the low bandwidth interface may be used more efficiently by load balancing between the low bandwidth interface and the high bandwidth interface.

Abstract: Embodiments of the present invention provide a resource allocation method and an apparatus. The method includes: determining, by a base station, a first physical resource to be allocated to a terminal and a resource allocation type; determining, by the base station according to the resource allocation type and a mapping relationship between a resource block unit and a physical resource, a first resource block unit corresponding to the first physical resource; and further sending, by the base station, resource allocation information to the terminal, where the resource allocation information includes the resource allocation type and indication information of the first resource block unit allocated by the base station to the terminal. In this way, a resource allocation method applied to a new system carrier is implemented. It can be ensured that when a new terminal transmits data by using the new system carrier, a conventional terminal can also transmit data by using a standard component carrier, that is, the new system carrier is compatible with the conventional terminal, so that resource utilization can be improved.

Abstract: The embodiments relate to an apparatus and method for streaming content to one or more user equipment devices in a telecommunications network, wherein the content is available for streaming at one of a plurality of different quality representations. The method comprises the step of receiving a request from a user equipment device, wherein the request is for delivery of a segment of the content at a first quality representation. It is determined whether the user equipment device is connected to a cell of the telecommunications network in which a congestion level of the cell is above a threshold level. If so, a fairness function is performed to determine if the segment of content should be streamed to the user equipment device at the requested first quality representation or a second quality representation. The segment of content is streamed to the user equipment device at the first quality representation or the second quality representation based on a result of performing the fairness function.

Abstract: There is discussed a method of transmitting data from a first network device to a second network device using a plurality of network links. The method comprises the first network device sending first data to the second network device over a first network link at a first transmission time and sending second data to the second network device over a second network link at a second transmission time. The first network device receives from the second network device an indication of the time difference between reception of the first data over the first network link and reception of the second data over the second network link. The first network device then calculates a propagation time difference between the time taken for the first data to reach the second network device over the first network link and the second data to reach the second network device over the second network link using the received time difference indication and the first and second transmission times, and determines a network link configuration and data sending order using the calculated propagation time difference.
