METHOD AND APPARATUS FOR HANDLING RELEASE OF SIMULTANEOUS COMMUNICATION WITH MULTIPLE BASE STATIONS AND RELATED COMMUNICATION DEVICE

摘要

A network node includes a communication interfacing unit and a processor. The processor operable to perform operations includes controlling the communication interfacing unit to establish at least one second RB with a secondary cell group (SCG) bearer type between the communication device and an auxiliary network node; and releasing one of the at least one second RB under a condition that, for a first time period, all of downlink data in at least one downlink buffer corresponding to the one of the at least one second RB is successfully transmitted or the at least one downlink buffer corresponding to the one of the at least one second RB is empty, and the auxiliary network node does not receive any request for an uplink grant allocation.

1. A network node comprising:
a communication interfacing unit configured for communicating with a communication device via a radio resource control (RRC) connection and at least one first radio bearer (RB) with a master cell group (MCG) bearer type; and a processor electrically connected with the communication interfacing unit, the processor operable to perform operations comprising:
controlling the communication interfacing unit to establish at least one second RB with a secondary cell group (SCG) bearer type between the communication device and an auxiliary network node; andreleasing one of the at least one second RB when it is determined that a first condition has been met for a first time period, wherein the first condition is that all of downlink data in all of at least one downlink buffer corresponding to the one of the at least one second RB is successfully transmitted or all of the at least one downlink buffer corresponding to the one of the at least one second RB is empty, and the auxiliary network node does not receive any request for an uplink grant allocation from the communication device.
