Abstract: A user equipment (UE) is configured to initiate a two-step random access channel (RACH) procedure to synchronize with a base station, initiate a fallback four-step RACH procedure after the two-step RACH procedure, configure a random access preamble transmission for the four-step RACH procedure, wherein configuring the random access preamble transmission comprises deriving a physical random access channel (PRACH) transmit power parameter value based on a parameter used to perform a transmission during the two-step RACH procedure and transmit the random access preamble for the four-step RACH procedure to the base station.

Abstract: The embodiments set forth techniques for managing connections for wireless devices configured for multiple Subscriber Identity Module (SIM) environments, such as dual SIM, dual standby (DSDS) environments. A common scenario involves a first wireless device receiving a voice call (e.g., using a first SIM of the first wireless device) while carrying out a data call with a second wireless device (e.g., using a second SIM of the first wireless device). In such a scenario, the data call is often disrupted due to the voice call, which can cause confusion to a user of the second wireless device. Accordingly, the techniques disclosed herein include the first wireless device providing, in conjunction with receiving the voice call, a notification of the voice call to the second wireless device. In turn, the second wireless device can inform the user of the event to help mitigate the aforementioned confusion.

Abstract: An apparatus configured to enable, based on user input, a call forwarding functionality for voice calls, process, based on user input, an identification of a communication device to which voice calls are to be forwarded, generate, for transmission to the communication device via a short-range connection, a forwarding request and process, based on signaling received from the communication device via the short-range connection, a forwarding response indicating whether the communication device has accepted the forwarding request.
