Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may support multiple radio access technologies (RATs). The UE may communicate using both a Long Term Evolution (LTE) connection for control signaling and a New Radio (NR) connection for data signaling in a non-standalone (NSA) mode. However, if the UE uses a data rate below a threshold, the NR connection may be inefficient. To reduce processing overhead, the UE may fall back to using the LTE connection for data communications. For example, the UE may delay or abort adding an NR connection based on the data rate. In some examples, the UE may transmit a fake report or a fake uplink message to trigger dropping an NR connection. Additionally or alternatively, the UE may indicate a preferred mode of operation to the network indicating a preference for communicating data via an LTE connection.

Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM. The wireless device may obtain system information block (SIB) scheduling information associated with the first SIM, and may create a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time. Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap.
