  • Patent number: 11799710
    Abstract: This disclosure provides methods, devices and systems for pre-compensation of downlink communication based on a transmission of a request for the pre-compensation from a user equipment (UE). For example, the UE may determine an impairment at the UE that has a greater severity (a greater impact on downlink communication) or is associated with a greater amount of resources for processing relative to a remainder of a set of impairments that is experienced at the UE and the UE may transmit a request for pre-compensation of the impairment by a base station. The base station may transmit feedback to the UE indicating a confirmation of pre-compensation for the impairment by the base station or to deferment of compensation for the impairment back to the UE. If the base station acknowledges pre-compensation for the impairment, the base station may pre-compensate a downlink transmission to the UE for the impairment.

A set of coefficients of the antenna array may be generated. In addition, an ensemble of non-linear forward models may be generated using the accuracy confidence value and the set of coefficients. Further, an array of pre-distortion signals may be generated using the ensemble of non-linear forward models, and each antenna of the array antenna may be configured with a corresponding pre-distortion signal from the array of pre-distortion signals.

  • Patent number: 11632161
    Abstract: A communication apparatus capable of wireless communication with another communication apparatus via a first communication path and a second communication path sets a directivity of an antenna to a first directivity capable of wireless communication via the first communication path and receives data from the another communication apparatus via the first communication path. When the communication apparatus sends an acknowledgement signal to the another communication apparatus via the first communication path in response to reception of the data, the communication apparatus sets the directivity of the antenna to a second directivity capable of wireless communication via the first communication path and wireless communication via the second communication path for a set period thereafter.

  • Patent number: 11601175
    Abstract: Methods, devices and computer programs for determining new transmit directions to use for beamformed transmissions in case the link quality of an existing direction falters. A transmitting communication device and a receiving communication device cooperate via a beam tracking procedure to determine a new suitable transmit direction to use for upcoming beamformed transmissions. Information relating to the beam tracking procedure is communicated over an existing link that enables communication between the transmitting and receiving communication devices. The receiving communication device provides the transmitting communication device with information about a beam scan performed in order to detect tracking beams transmitted by the transmitting communication device. This information allows the transmitting communication device to determine suitable transmit directions to use.

  • Patent number: 11595906
    Abstract: A wireless device receives: a first maximum total transmit power allowed for a first cell group of a first type of radio access technology; and a second maximum total transmit power allowed for a second cell group of a second type of radio access technology. It is determined that a total transmission power exceeds a value based on: a first power for transmission of first uplink signal(s) via the first cell group, and a second power for transmission of second uplink signal(s) via the second cell group. The first and second powers are less than or equal to the first and second maximum total transmit powers respectively. Scheduled transmission of the first uplink signal(s) of the first cell group is dropped in response to the first cell group being of the first type of radio access technology. Second uplink signal(s) are transmitted to a base station.
