Abstract: The techniques described herein may include solutions for using downlink control information (DCI) to indicate dormancy for secondary cells (SCells). For DCI without a specific field for indicating dormancy for SCells, one or more fields of the DCI may be repurposed to report SCell dormancy. Repurposed fields may be arranged according to radio resource control (RRC) configuration information, a most significant bit (MSB), a least significant bit (LSB), and/or one or more bits being directed to specific SCell dormancy with one or more other bits being directed to SCell group dormancy, subsets of SCells, and/or a pre-defined rule. These and many other features and examples are described herein.

Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.
