    Abstract: Methods and systems are disclosed for a UE to manage and measure intra-cell cross link interference (CLI) when served by a base station operating in full-duplex FDD. The signaling may indicate to a victim UE resources to measure to determine the level of CLI from aggressor UEs. The resources used for the CLI measurement may be resources not scheduled by the base station for use by the victim UE for downlink reception, but are scheduled for use by the aggressor UEs for transmitting uplink traffic or for transmitting reference signals used to characterize the uplink channel. The victim UE may report the CLI measurements to the base station for the base station to adjust scheduling of downlink resources to the victim UE. In one aspect, the signaling from the base station may indicate to the victim UE the locations of scheduled downlink symbols that may potentially be impacted by CLI.

    Abstract: A coax network unit (CNU) is coupled to a coax line terminal (CLT). In first and second modes of operation, the CNU transmits data during an upstream window and receives data during a downstream window. In the first mode of operation, a duration of data transmission for the upstream window or a duration of data reception for the downstream window is reduced by a specified amount with respect to the second mode. A sounding signal is transmitted in the first mode in a probing slot that has a duration corresponding to the specified amount.

    Abstract: 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.

    Abstract: Separation of sub-bands of communications signals to reduce interference in distributed antenna systems (DASs) is disclosed. A sub-band separation circuit coupled to a plurality of antennas is configured to distribute and receive and transmit a pair of downlink and uplink sub-band signals. The sub-band separation circuit is coupled to a duplexed port of a remote unit that distributes uplink communications signals to the DAS and receives downlink communications signals from the DAS. In order to isolate the downlink communications signals from the uplink communications path in the remote unit, the isolation circuit includes a plurality of sub-band isolation circuits. Each sub-band isolation circuit is configured to isolate at least one sub-band of the downlink communications signal to generate a downlink sub-band signal that has a desired frequency separation or gap with uplink communication signals received at the duplexed port.
