摘要： A radio frequency front end system has a first transmit path and a first receive path. There is a first transmit filter within the first transmit path and a first receive filter within the first receive path. One or more switches can be configured to selectively connect a first antenna to the first transmit filter and to selectively connect a second antenna to the first receive filter to allow frequency division duplex communication over the first transmit path and the first receive path in which the first transmit path transmits over the first antenna simultaneous with the first receive path receiving over the second antenna.

摘要： A full-duplex transceiver is provided with componentry and methods for cancellation of nonlinear self-interference signals. The transceiver is capable of receiving an incoming radio-frequency signal that includes both a desired radio-frequency signal component and a self-interference component caused by the transceiver's own radio-frequency transmission. The transceiver demodulates the incoming radio-frequency signal to generate a first demodulated signal. The transceiver combines an analog corrective signal with the first demodulated signal to generate a second demodulated signal with reduced self-interference. The transceiver processes the first and second demodulated signals to determine a desired incoming baseband signal and to determine nonlinear components of the self-interference signal, such as nonlinearities introduced by the transceiver's power amplifier.

摘要： A method for operating a transmission-reception point (TRP) includes determining a first cycle of backhaul communications modes for the TRP, each backhaul communications mode of the first cycle is associated with a different time period and prompts the TRP to either transmit or receive using a subset of communications beams available to the TRP during an associated time period, wherein the communications beams used by the TRP and neighboring TRPs of the TRP in each associated time period are selected to prevent mutual interference, and wherein at least one backhaul communications mode of the first cycle prompts the TRP to either transmit or receive using all of the communications beams available to the TRP, determining a backhaul frame configuration for the TRP in accordance with the first cycle, the backhaul frame configuration specifying an arrangement of subframes of a frame used for backhaul communications.

摘要： Embodiments herein describe apparatuses, systems, and methods for signaling to support downlink coordinated multipoint (CoMP) communications with a user equipment (UE) in a wireless communication network. In embodiments, the UE may be configured with a plurality of channel state information (CSI) processes (e.g., via radio resource control (RRC) signaling) to use for providing CSI feedback to an evolved Node B (eNB) to support downlink CoMP communications. The UE may be configured with a plurality of sets of CSI processes. The UE may further receive a downlink control information (DCI) message from the eNB that indicates one of the configured sets of CSI processes on which the UE is to provide CSI feedback to the UE. The UE may generate the CSI feedback for the indicated set of CSI processes, and transmit the CSI feedback to the eNB in a CSI report.

摘要： A communication system includes a conversion module configured to convert a signal between a radio frequency baseband (RF-BB) and an intermediate frequency (IF). At least one RF front-end module converts the signal between the IF and a radio frequency (RF). The RF front-end module is configured as an RF phased array and includes a coaxial interconnect configured to connect the conversion module with the RF front-end module. The signal is transmitted between the conversion module and the RF-front end module via the coaxial interconnect. At least one RF front-end module includes an active front-end (AFE) configured to allow the signal to be transmitted via the coaxial interconnect while minimizing any deterioration of the signal.
