Abstract: Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

Abstract: Apparatuses and methods for a wireless communication device having a first Subscriber Identity Module (SIM) and a second SIM to manage communication via the first SIM and the second SIM are disclosed. The method can include, but is not limited to, sending a first message including an indication of an extended signaling capability, receiving a second message including an inquiry regarding the extended signaling capability, and sending a third message including extended capability information, responsive to receiving the second message.

Abstract: Aspects of the present disclosure provide mechanisms for fast hyper frame number (HFN) resynchronization of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs). A wireless communication device (e.g., a PDCP entity at a wireless communication device) can calculate a current PDCP count of a current PDCP PDU of a plurality of PDCP PDUs received from a radio link control (RLC) sublayer based on a PDCP sequence number (SN) of the current PDCP PDU and an HFN of a first missing PDCP PDU after a successfully received PDCP PDU. The PDCP count may be calculated using the HFN of the first missing PDCP PDU in response to a gap between the PDCP count of the first missing PDCP PDU and the actual PDCP count of the current PDCP PDU being greater than a PDCP window size.

Abstract: A receiving device re-establishing a packet data convergence protocol (PDCP) entity. The receiving device resets a robust header compression (ROHC) context. The receiving device receives packet retransmissions having header compression based on the ROHC. The receiving device performs decompression of the packet retransmissions. The receiving device discards duplicate packets after performing the decompression of the packet retransmissions.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving buffer size setting for one or more buffer status reports, such as one or more extended buffer status reports (eBSRs) in a wireless communication system. According to certain aspects, a method is provided herein for wireless communications performed by a user equipment (UE). The method generally includes determining a first amount of data stored in a buffer at the UE; and if the first amount of the data satisfies (e.g., is equal to or greater than) a threshold, sending a first BSR indicating a second amount of buffered data at the UE greater than the first amount. As a result, the UE may be scheduled by the base station for a greater amount uplink resources for transmitting the buffered data.
