Patent ID: 8837423

Claim:
A serving node apparatus for communicating with at least one of a plurality of customer equipments, comprising: a transceiver comprising an antenna configured to transmit and receive data from at least one of a plurality of customer equipments; a control processor configured to, in response to a requesting handover message indicating handover to a target node, transmit to the target node a sequence number message, wherein the sequence number message was successfully received by the at least one customer equipment; and a memory configured to store data to be transmitted to the at least one customer equipment, wherein after receiving the requesting handover message, the transceiver transmits the data to the at least one customer equipment at a lower Modulation and Coding Scheme (MCS) level than before receiving the requesting handover message, the lower MCS level having a lower coding rate and a lower modulation order, and wherein if a lowest MCS level is used for transmitting the data before receiving the requesting handover message, the control processor allocates additional resources for transmitting the data and the transceiver transmits the data using the additional resources at the same MCS level as before receiving the requesting handover message.
