    Abstract: QoS based uplink data buffering while TTI bundling is enabled by a wireless user equipment (UE) device. The UE may establish a packet-switched connection with a network via a wireless link. The UE may receive, at a media access control (MAC) layer, an indication to enable TTI bundling. The UE may selectively buffer uplink data at an application layer based on the indication to enable TTI bundling. The uplink data may be buffered selectively based on Quality of Service (QoS) considerations. Uplink transmissions may subsequently be performed using TTI bundling.

    Abstract: A method performed by stations to transfer call sessions between different access networks. The methods include transmitting, by a first station to a second station, an invite to join a voice call on a first radio access network (RAN), receiving, by the second station, the invite, generating, by the second station, a response to the invite, determining, by the second station, that the response cannot be successfully transmitted to the first station, associating, by the second station, with a second RAN, generating, by the second station, a message indicating the second station has associated with the second RAN, transmitting, by the second station, the message to the first station, retransmitting, by the first station, the invite to join the voice call, receiving, by the second station, the invite on the second RAN and setting up the voice call between the first station and the second station.

    Abstract: A method for reducing power consumption in connected mode discontinuous reception is disclosed. The method can include a wireless communication device sending a transmission for a pending HARQ retransmission process and receiving an ACK for the transmission. The method can further include the wireless communication device determining a subset of remaining uplink transmission opportunities in the pending HARQ retransmission process to monitor for an uplink grant in response to receiving the ACK and monitoring the subset of remaining uplink transmission opportunities for an uplink grant. The method can additionally include the wireless communication device entering a sleep state for any uplink transmission opportunities remaining in the pending HARQ retransmission process after monitoring the subset of remaining uplink transmission opportunities in an instance in which an uplink grant for the pending HARQ retransmission process is not received for any of the subset of remaining uplink transmission opportunities.
