Embodiments of the present invention disclose a bandwidth control method and a bandwidth control device to reduce impact of mobile terminal access on user experience of a fixed terminal. The method includes: obtaining, by a bandwidth control device, an access request of a mobile terminal, where the access request is used to indicate that the mobile terminal requests to access the Internet by using a home gateway of a fixed terminal; obtaining, by the bandwidth control device, a first bandwidth of the fixed terminal, where the first bandwidth is a subscribed bandwidth of the fixed terminal; and adjusting, by the bandwidth control device, a bandwidth allocated to the fixed terminal to a second bandwidth, where the second bandwidth is greater than the first bandwidth. In the embodiments of the present invention, the impact of mobile terminal access on user experience of the fixed terminal can be reduced.

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.

Embodiments of the claimed subject matter provide for methods and systems of QoS negotiation for services like network assisted adaptive streaming. The QoS reservation determination is based on both a QoS policy of a network service provider and a QoS policy of a content service provider. For example, the content service provider provides a video streaming service. The QoS reservation can include a guaranteed bit rate (GBR) and/or a maximum bit rate (MBR). The QoS reservation can be used to select a representation of a media file for adaptive streaming.

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.

Disclosed are a user terminal device and a control method therefor. The control method for a user terminal device according to the present invention comprises the steps of: determining state information of a satellite device connected with a user terminal device when a call request message is received from another terminal device; determining communication configuration information with the another terminal device on the basis of the state information of the satellite device, and transmitting a call response message including the communication configuration information to the another terminal device; and receiving audio data from the another terminal device according to a communication scheme corresponding to the communication configuration information. Therefore, in comparison with the prior art, the present invention can reduce a call negotiation time between user terminal devices, and thus reduce a call cost.

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.

The present invention provides a method and a system for transmitting data that carries indication information, and an apparatus. The method includes: generating, by a transmit end node, an indication frame; and sending, by the transmit end node, the indication frame to a receive end node, where the indication frame includes available-channel indication information or idle bandwidth information. The receive end node can directly receive indication frames sent by multiple transmit end nodes, and does not need to receive, one piece by one piece, indication information sent by the multiple transmit end nodes. This greatly reduces transmission overheads.

Embodiments of the present invention propose a data transmission method, including: determining, according to a maximum power value detected by performing a CCA on a primary channel in one or more processing time periods, a power value interval to which the maximum power value detected by performing the CCA belongs, where the determined power value interval is one of one or more power value intervals that do not overlap each other; obtaining a transmit power spectral density according to the determined power value interval, where there is a one-to-one correspondence between the one or more power value intervals and one or more transmit power spectral densities; and when a TXOP is obtained, performing data transmission on a transmission channel by using a power spectral density that is not greater than the transmit power spectral density. A corresponding power value interval is determined by considering a maximum power value detected by performing a CCA on a primary channel, so as to obtain a transmission channel and a transmit power spectral density that are most suitable for a current channel status, so that a probability of accessing a channel by a station is increased, and the station may use a power spectral density as large as possible to perform data transmission, so as to maximize transmission efficiency of a system.

A method for wireless communication is described herein. The method may include advertising support by a wireless device for a first bandwidth mode and a second bandwidth mode, wherein the first bandwidth mode utilizes a single channel and the second bandwidth mode utilizes channel bonding between a plurality of channels. The method may also include switching a current bandwidth mode of the wireless device from one of the bandwidth modes to the other of the bandwidth modes and adjusting a number of multiple-input, multiple-output (MIMO) spatial streams supported by the wireless device in response to the switching.
