Abstract: Aspects are presented herein of apparatuses, systems, and methods for secondary cell group (SCG) addition. A wireless device may establish communication with a first base station that is comprised in a master cell group (MCG) and a second base station that is comprised in the SCG. The wireless device may maintain timing advance (TA) parameters for performing uplink communication with the second base station. The wireless device may perform a plurality of signal quality measurements after receiving an indication to deactivate the SCG. The wireless device may determine whether to reuse the TA parameters for communicating with the second base station after receiving an indication. The determination may be based on comparing one or more signal quality measurements of the second base station to one or more signal quality thresholds.

Abstract: Aspects are presented herein of apparatuses, systems, and methods for secondary cell group (SCG) addition. A wireless device may establish communication with a first base station that is comprised a master cell group (MCG). The wireless device may receive signaling from the first base station configuring a second base station in a secondary cell group (SCG). The wireless device may establish communication with the second base station based on the signaling received from the first base station. At a first time, the wireless device may set the second base station in a deactivated state based on the signaling from the first base station configuring the second base station or establishing communication with the second base station. At a later time, the wireless device may set the second base station in an activated state and communicate with the first base station and the second base station.

Abstract: This disclosure relates to techniques for supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.
