摘要： Wireless communication systems and methods are provided that include at least one base transmitter unit, at least one repeater unit, at least one receiver, and an artificial intelligence unit. The base transmitter unit is configured to transmit a data signal. The repeater unit is in communication with the transmitter and is configured to transmit the data signal via sky wave propagation. The receiver is in communication with the transmitter and the repeater and is configured to receive the data signal. The artificial intelligence unit monitors ionospheric conditions in the area and controls the data signal, making adjustments so the data signal overcomes skip zones. The adjustments may include automatically adjusting the power and position of the antenna array to re-route the data signal and/or dynamically changing the frequency of the data signal.

The controller is configured to receive a plurality of terrestrial return link signals from a plurality of user terminals, the plurality of uplink signals having a second frequency. The controller is configured to generate a repeated, terrestrial downlink signal based on the satellite downlink signal. The controller is configured to generate a repeated satellite uplink signal that is a linearly amplified version of the combined terrestrial uplink signals. The controller is configured to transmit the repeated downlink signal at the first frequency. The controller is configured to transmit the combined uplink signal at the second frequency.

摘要： A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

摘要： A device may receive channel monitoring information associated with an unlicensed radio frequency (RF) spectrum band. The device may determine channel availability information associated with one or more channels of the unlicensed RF spectrum band based on the channel monitoring information. The channel availability information may include one or more channel availability parameters, corresponding to the one or more channels, that indicate availability for communicating via the one or more channels. The device may receive, from an access point that provides network access via the unlicensed RF spectrum band, a request for a channel recommendation associated with the unlicensed RF spectrum band. The device may determine a set of recommended channels of the unlicensed RF spectrum band based on the channel availability information and the request for the channel recommendation. The device may provide, to the access point, information that identifies the set of recommended channels.

摘要： Methods and apparatus for subframe configuration and generation in a multi-cell multi-carrier system. A frame for radio transmission in the system consists of multiple subframes, and each subframe consists of multiple Orthogonal Frequency Division Multiplexing (OFDM) symbols. Training symbols, frequency-domain data scrambling, size of Fast-Fourier Transform (FFT), or length of cyclic prefix can be configured differently for each subframe to facilitate different applications, such as unicasting or broadcasting.

摘要： The present invention is designed to reduce interference from a macro base station to a small transmission power node. The present invention is characterized in providing a micro base station which forms, in a macro cell where a macro base station transmits a signal to a macro terminal, a micro cell where the micro base station transmits a signal to a micro terminal under control with low power, and this micro base station generates a PDCCH which includes downlink or uplink resource allocation information, and, in a non-transmission period in which the macro base station stops transmitting signals while leaving minimal quality measurement signals, shifts the transmission starting symbol of the PDCCH to a position where the PDCCH does not overlap the quality measurement signals.

摘要： Methods, systems, and devices are described for broadcast signal transmission using a number of nodes in an unlicensed spectrum. A set of nodes may be identified for use in transmission of a broadcast signal, with a first subset of the nodes transmitting the broadcast signal to deliver first content during a first time period, and with a second subset of the nodes transmitting the broadcast signal to deliver second content during a second time period. The first subset of nodes is different than the second subset of nodes. The set of nodes may thus form a single frequency network (SFN) that performs partial SFN operation during the first and second time periods.
