Abstract: In some aspects, a user equipment (UE) may receive a configuration from a base station that indicates whether to use a first channel quality indicator (CQI) table from a first set of CQI tables associated with terrestrial network communications or whether to use a second CQI table from a second set of CQI tables associated with non-terrestrial network communications. The UE may transmit CQI feedback to the base station based at least in part on the configuration. The UE may transmit the CQI feedback using the first CQI table when the configuration indicates that the first CQI table is to be used or may transmit the CQI feedback using the second CQI table when the configuration indicates that the second CQI table is to be used.

Abstract: An apparatus communicates using a first Radio Access Technology (RAT) and a second RAT. The apparatus receives a first Time Division Duplex Uplink/Downlink (TDD UL/DL) configuration for a first cell using the first RAT. The apparatus also receives a second TDD UL/DL configuration for a second cell using the first RAT. Additionally, the apparatus determines a maximum transmission power for a first transmission using the second RAT based on whether there is a potential overlap between the first transmission using the second RAT and a possible transmission based on the first TDD UL/DL configuration or the second TDD UL/DL configuration during a period of the first transmission or an extended period including the first transmission period.

Abstract: Certain aspects of the present disclosure provide techniques for multiple radio access technology (RAT) carrier aggregation (CA), such as Long Term Evolution (LTE)-New Radio (NR) CA. The method, in one example, comprises generating a first resource coordination information (RCI) comprising one or more resource coordination bitmaps indicating one or more shortened transmission time intervals (sTTIs) of a TTI assigned to the first RAT for communication, wherein the TTI comprises a plurality of sTTIs. The method further comprises transmitting a message including the first RCI to a second base station that uses a second RAT. The method further comprises receiving an acknowledgement of the message from the second base station, the acknowledgment including a second RCI comprising one or more modified resource coordination bitmaps indicating the one or more sTTIs assigned to the first RAT for communication and one or more additional sTTIs of the TTI assigned to the second RAT.

Abstract: Aspects described herein relate to configuring, at a device, default beam information for determining a beam for data channel communications. The device can determine to use the default beam information for configuring the beam for a data channel communication based on determining explicit beam information is not configured. In addition, the device can transmit, based on determining to use the default beam information, the data channel communication based on the beam configured using the default beam information.

Abstract: Certain aspects of the present disclosure provide techniques for carrier independent signal transmission and reception. Certain aspects provide a method for wireless communication. The method includes applying, at a device, a phase correction to a first signal to compensate for a difference between a first zero tone location comprising a first frequency and a second zero tone location comprising a second frequency. The method further includes one of: transmitting the first signal after applying the phase correction; or receiving the first signal prior to applying the phase correction.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for power control. For example, a method is provided for wireless communication by a user equipment that includes determining whether a sum of a first power limit for communicating on an uplink associated with a first radio access technology and a second power limit for communicating on an uplink associated with a second radio access technology is greater than an overall power limit for communicating on uplinks by the user equipment. The method further includes scaling down power used for a transmission on the uplink associated with the first radio access technology during the first time or dropping a transmission on the uplink associated with the first radio access technology during the first time when the sum is greater than the overall power limit.
