Abstract:
An object of the present invention is to provide a digital broadcast reception apparatus that allows a stable viewing even if a reception environment changes along with a movement. In the present invention, based on current position information indicating a current position detected by a current position detection section (35) and broadcast area information stored in a broadcast area information storage section (34), a search-mode switching control section (36) instructs a tuning control section (33) to select a diversity operation mode if the current position is close to a boundary of a broadcast area, and select an independent reception operation mode if the current position is not close to the boundary of the broadcast area. In the diversity operation mode, a first system (10) and a second system (20) are tuned to the same physical channel, and cooperate with each other to demodulate a digital broadcast signal and a make an output through a diversity process. In the independent reception operation mode, the first system (10) and the second system (20) individually and independently demodulate the digital broadcast signal and make an output.

The transmission mode selecting method includes: obtaining a first system capacity in a half-duplex transmission mode; obtaining a second system capacity in a full-duplex transmission mode, where the second system capacity is the maximum value among system capacities of a universal set of candidate antenna TX/RX combinations in the full-duplex transmission mode, or the maximum value among system capacities of a first subset of the candidate antenna TX/RX combinations in the full-duplex transmission mode, or a system capacity exceeding a system capacity threshold; and selecting a target transmission mode according to a comparison result between the first system capacity and the second system capacity, where the target transmission mode is a transmission mode corresponding to a larger value between the first system capacity and the second system capacity. That is, in the current channel condition where a multi-antenna system is running, a transmission mode enabling the system capacity to be increased or maximized is selected according to a system capacity increasing or maximizing rule, so as to achieve favorable or optimal system performance in current channel conditions of the system.

Abstract:
Methods, devices, and computer-readable media for wireless communication may involve techniques for managing multi-user (MU) operation when a device in a wireless network has coexisting radios. Such techniques may involve identifying a change in a multiple radio access technology (RAT) coexistence status of a first device, e.g., a change between a coexistence status that is not disruptive to MU communications and one that is disruptive. For a device communicating with a network using Wi-Fi, the change in the multiple RAT coexistence status may indicate a change between inactive Bluetooth (BT) communications and active BT communications concurrent with Wi-Fi communications. Based at least in part on the identified change in the multiple RAT coexistence status, a MU communications operation at a second device may be adjusted, for example, by disabling MU communication between the first and second devices over a first RAT when the first device changes to a coexistence status that may disrupt MU communications.

Ein Fluggerät weist mindestens zwei Antenneneinheiten und eine zentrale Steuereinheit auf. In einem ersten Betriebsmodus senden bzw. empfangen die zwei Antenneneinheiten voneinander unabhängig Signale in verschiedenen, nicht-überlappenden Frequenzbändern. Die zentrale Steuereinheit ist konfiguriert, die zwei Antenneneinheiten in einem zweiten Betriebsmodus derart zu steuern, dass sie in einem gemeinsamen Frequenzband unter Ausnutzung von Multiple Input Multiple Output (MIMO)-Übertragungstechnik ein gemeinsames Signal übertragen und/oder empfangen.
