NODE B AND RNC ACTIONS DURING A SERVING HSDPA CELL CHANGE

摘要

An apparatus and method in accordance with the present invention reduce the amount of data that is stalled in a source Node B after a serving HS-DSCH cell change in a communication system that includes a serving RNC and at least one Node B. In a first embodiment, the RNC temporarily suspends data transmissions from the RNC to the Node B. In a second embodiment, the activation time is used in data scheduling. In a third embodiment, a more robust MCS level is selected. In a fourth embodiment flow control is employed for the data transmitted between the RNC and the Node B.

主权项

1. A method for efficient delivery of data in wireless communications that includes a radio network controller (RNC) associated with at least one Node B, the at least one Node B communicating with a plurality of user equipments (UEs), and at least one of the plurality of UEs communicating within a cell and undergoing a high-speed downlink shared channel (HS-DSCH) cell change, the method comprising:
determining at the RNC the need for an HS-DSCH cell change and for generating a notification to the at least one Node B regarding the cell change; suspending at the RNC all further data transmissions to the at least one Node B serving the at least one UE; and sending from the RNC to the at least one Node B the notification.
