Abstract: User Equipment (UE) based forced inter radio access technology (iRAT) handover. A connection to a network may be established via a first cell operating according to a first radio access technology (RAT). It may be determined to initiate a handover of the UE from the first cell to a second cell operating according to a second RAT. An indication may be transmitted to the network to initiate a handover of the UE from the first cell to the second cell. An indication may be received from the network to perform handover of the UE from the first cell to the second cell in response to the indication to initiate the handover. Handover of the UE from the first cell to the second cell may be performed in response to the indication to perform the handover. Handover may include releasing the connection to the network via the first cell and establishing a connection to the network via the second cell.

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.
