Abstract: Methods, systems, and devices for wireless communications are described. A wireless node may receive one or more data messages which may include a set of packets that may each be associated with a sequence number. The set of packets may be received with a gap in the set of sequence numbers, indicating missing packets. The wireless node may forward the set of packets to a processing layer of the wireless node. The wireless node may then accept, from the processing layer of the wireless node, a set of duplicate (DUP) acknowledgment (ACK) messages based on the set of packets being forwarded to the processing layer while having the gap in the set of sequence numbers. The wireless node may transmit, a subset of the set of DUP ACKs rather than all of the set of DUP ACKs to another wireless node, such as a base station.

Abstract: Aspects are provided allowing a MSIM UE to transmit a controlled pattern of fake HARQ-ACK and a controlled RLC status report in response to un-decoded data transmissions from a base station, while suspending SRS antenna switching during performance of an activity in a different network subscription, in order to relieve MCS penalties in response to such suspension while minimizing RLC holes. The UE sends a plurality of SRSs to a base station in a first network using a first SIM of the UE, where each of the SRSs is sent using a different antenna. The UE suspends SRS transmission from the different antennas while performing an activity in a second network using a second SIM of the UE. The UE sends a HARQ-ACK to the base station while the SRS transmission is suspended in response to at least one of a plurality of un-decoded data transmissions from the base station.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an application processor associated with the UE, an indication of a traffic service type and whether an uplink data stall has occurred. The UE may detect that one or more threshold criteria are satisfied for a serving cell, wherein a threshold value associated with at least one of the one or more threshold criteria is based at least in part on the traffic service type. The UE may transmit information associated with one or more adjusted measurement values of the serving cell based at least in part on detecting that the one or more threshold criteria are satisfied. Numerous other aspects are described.

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.
