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 disclosed herein include capturing images via cameras or light sensors of a mobile communication device, processing the image to determine obstructed (e.g., by foliage) portions and unobstructed (e.g., open sky) portions of the images, and generating a grid indicating the obstructed and unobstructed portions. The device may then adjust operating characteristics, such as synchronizing with a communication hub or other mobile communication device, performing a handover with the communication hub or other mobile communication device, determining transmission power or an amount to increase transmission power, selecting an antenna, determining a beam direction, determining a discontinuous reception cycle or a frequency for receiving data, providing an indication to stop or proceed through certain areas (e.g., to take advantage of areas with higher signal quality or avoid areas with lower signal quality), and the like, based on the obstructed and unobstructed portions identified in the grid.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for communicating in a first radio access technology (RAT) and a second RAT. A user equipment (UE) can receive, from a first base station using the first RAT, first configuration information for the UE to communicate with a second base station via the second RAT; and receive, from the first base station using the first RAT, a downlink message to enable a communication link between the UE and the second base station via the second RAT. The downlink message includes second configuration information for the UE to communicate with the second base station via the second RAT. The UE can establish the communication link between the UE and the second base station using the second RAT based on a link configuration obtained from the first configuration information and the second configuration information.

Abstract: While a circuit service, CS, call is in progress, a request for a packet service, PS, call is received from a background task that is running in the mobile communications user equipment. In response to receiving the request, several air interface parameters that relate to the in-progress CS call are evaluated, in order to decide whether or not to block the PS call based on the evaluation. Other embodiments are also described and claimed.
