  • Publication number: 20240080780
    Abstract: Apparatuses, systems, and methods for providing maximum transmit power control when utilizing multiple radio access technologies. For example, a wireless communication device comprising two cellular radios may intend to transmit on the first radio, while concurrently transmitting on the second radio. To ensure compliance with a maximum transmit power limitation, the device may determine an allowed transmit power level of the first radio, representing a difference between the maximum transmit power limitation and the current transmit power level being transmitted by the second radio. The device may also determine a threshold power level for a communication by the first radio. If the allowed transmit power level meets the threshold power level, then the device may transmit the first communication having a power level between the threshold power level and the allowed transmit power level. Otherwise, the device may forego transmission of the first communication.

  • Publication number: 20230397218
    Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.
