  • Patent number: 11895057
    Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. An aggressor BS may cause a remote interference condition for a victim BS, and the victim BS may transmit a reference signal to the aggressor BS to enable a remote interference management (RIM) operation to be performed. However, the aggressor BS may be unable to identify the victim BS based at least in part on the reference signal, and may fail to transmit a reference signal as a response. Further, when the aggressor BS does transmit a reference signal, the victim BS may be unable to identify the aggressor BS. This may reduce an effectiveness of RIM operations. In some aspects, BSs may transmit reciprocal reference signals including identification information to enable effective RIM operations.

  • Publication number: 20240040555
    Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 11889436
    Abstract: The transmission and reception group delay in a front end structure of a mobile device may be determined using closed loop calibration. The closed loop may be a near field radiated closed loop between pairs of antennas in an antenna array of the mobile device. The delay based on time of transmission and time of reception may be measured for a plurality of pairs of antennas, from which the transmit and receive group delay within a single path may be determined. The propagation delay of the signal between antennas may be included in the group delay calibration for increased accuracy. In another implementation, a conducted closed loop, e.g., in the transceiver or in a radio frequency switching network may be used to calibrate the group delay. Pre-characterization of the delay caused by components between the closed loop and antennas may be included in the group delay calibration for increased accuracy.
