摘要:
Embodiments of the present invention provide a bandwidth selection method of a Wireless Fidelity technology and an AP, and in the method, the AP obtains a negotiation bandwidth negotiated by the AP and a station STA. The method includes: receiving, by the AP, a data transmission request of the STA; obtaining, by the AP, a transmission bandwidth upper limit of the STA; and delivering, by the AP, a first MCS to the STA if the transmission bandwidth upper limit is less than the negotiation bandwidth, where the first MCS is less than an MCS that is corresponding to the negotiation bandwidth and that is in a correspondence between a bandwidth and an MCS, and is greater than or equal to an MCS that is corresponding to the transmission bandwidth upper limit and that is in the correspondence between a bandwidth and an MCS. It can be learned that in the embodiments of the present invention, not only the negotiation bandwidth negotiated by the AP and the STA is considered, but also the transmission bandwidth upper limit of the STA is considered, and a finally delivered MCS is reduced according to the transmission bandwidth upper limit of the STA in some scenarios of improper high transmission bandwidths, thereby reducing a delivered transmission bandwidth. Therefore, power consumption of access point AP and station STA side devices is reduced, and a standby time thereof is increased.

Methods and systems for dynamically controlling per-session throughput and application priority are provided. Said method is under the control of one or more computer systems configured with executable instructions. The method comprises receiving, at a mobile virtual network operator, a request to initiate a data-based application. The request is received from a mobile device that is associated with a data plan that is managed by the mobile virtual network operator. The data-based application is associated with a category of data. The method also comprises evaluating the request at a feedback-based packet control system of the mobile virtual network operator utilizing a speed monitoring module and business rule engine in evaluating the request. The method further comprises allocating data to the data-based application request. The allocation of data is based on a data plan and and/or category of data. Additionally, the method comprises providing the data-based application request to a server.
摘要:
Technologies are presented for enabling a relatively low power, limited range communications system (or, alternatively, a terminal in a directional, point-to-point communications link), using native data communications services provided by an overlying wireless network, to automatically (or semi-automatically) negotiate with that network for use of specific portions of the frequency band or bands that are used in common by the low power device and the overlying network. Frequency management capabilities inherent to the wireless network may be utilized to automatically execute the resulting frequency use coordination. Through the coordination, the low power (or point-to-point) communications system may be protected from potentially excessive interference from the overlying network and/or user devices operating on that network (and vice-versa) while minimizing any impact on performance and capacity of the overlying network.

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.
