Abstract: A method, a computer-readable medium, and an apparatus for switching between a first radio access network (RAN) using the first radio access technology (RAT) and the second RAN using a different, second RAT are provided. The method includes switching a wireless device operating at a first signal frequency in the first RAN to a second RAN and switching from the second RAN back to the first RAN. In an aspect, the wireless device is switched to one of the cells operating at the first signal frequency in the first RAN if each signal parameter from the one of the cells satisfies a criterion. The wireless device is otherwise switched to another one of the cells operating at a second signal frequency in the first RAN based on parameters from the another one of the cells. The first signal frequency is different from the second signal frequency.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects. a user equipment (UE) may transmit a first message of a four-step random access channel (RACH) procedure to a base station. The UE may receive a second message of the four-step RACH procedure. The UE may transmit a third message of the four-step RACH procedure. The UE may determine that the third message was not successfully decoded by the base station. The UE may retransmit the third message based at least in part on applying a power boosting algorithm to increase an uplink transmission power. wherein the power boosting algorithm is applied based at least in part on a power offset between the third message and the first message satisfying a threshold and a transmit power control (TPC) command not being received from the base station. Numerous other aspects are described.

Abstract: Aspects relate to methods and apparatus for dedicated bearer (DB) establishment handling during call setup for long term evolution. According to aspects, a method is provided herein for wireless communications that may be performed, for example, by a user equipment (UE). The method generally includes establishing a connection with a first access point (AP) to perform a call set up procedure for a call; receiving from the first AP a message associated with handover to a second AP; delaying giving up the call setup procedure for a duration if the message includes or is associated with an indication to release a dedicated bearer; and allowing establishment of a DB with the second AP during the duration. Consequently, the DB can be established with the second AP, without the UE giving up the call setup, and the call can be performed, thus improving user experience. Numerous other aspects are provided.
