  • Patent number: 10912030
    Abstract: Selectively controlling transmit power from a radio access network (RAN) cell to user equipment (UE) in closed-loop power control for uplink control channel based on variation in measured uplink signal quality. To avoid the RAN cell continuously sending transmit power control messages that may not be effective in further adjusting transmit power of the UE, the RAN cell selectively controls transmit power of the UE based on effectiveness in such transmit power control changing uplink channel signal quality. The determined effectiveness of the transmit power control can be used by the RAN cell to determine when the next transmit power control message should be sent to the UE. The RAN cell can be configured to indirectly measure the uplink channel power by reviewing the received uplink channel quality in a report communicated from the UE to the RAN cell.

  • Patent number: 10887079
    Abstract: Digital predistortion (DPD) timing alignment in a remote unit(s) for a wireless communications system (WCS) is disclosed. In examples discussed herein, a remote unit includes a power amplifier (PA) configured to amplify a radio frequency (RF) signal before transmission. The RF signal may include an unwanted distortion term and a DPD circuit is provided in the remote unit to create an artificial distortion term to help cancel out the unwanted distortion term. The remote unit includes a DPD front-end circuit configured to generate a digital training signal corresponding to a predefined waveform pattern. The DPD circuit can be configured to perform a DPD timing alignment based on the predefined waveform pattern to determine a timing offset that is need to create the artificial distortion term. As such, it may be possible to effectively cancel the unwanted distortion term in the RF signal to improve efficiency and linearity of the PA.

  • Patent number: 10756786
    Abstract: Isolation for antennas in a wireless communication system is achieved between transmit and receive paths for a multiple input multiple output (MIMO) antenna array by separating a first transmit path from an associated receive path to be matched with a second transmit path and matching the first receive path with the second receive path. It is expected that the two transmit paths operate on sufficiently different frequencies that there is minimal interference there and the additional spacing from the transmit path to the receive path will reduce interference therebetween without increasing a footprint of the antenna array.
