Abstract: According to an exemplary embodiment, a method with antenna selection in a communication system may support an antenna selection function at a central node having a plurality of antennas; and co-schedule multiple distributed nodes to the same resource in a downlink channel from the central node to the multiple distributed nodes by using multiple precoders related to the multiple distributed nodes to provide a system performance gain; wherein the multiple precoders are under one of conditions of partially overlapped antenna selection, non-overlapped antenna selection, and fully overlapped antenna selection.

Abstract: A method of a transient handover for performing packet offloading is disclosed. The method is used in a cellular network and includes: finding at least one qualified user equipment according to a determining method, and transmitting a handover-transient request to the qualified UE; finding and transmitting an access request to a wireless local area network after the UE receives the handover-transient request; transmitting a handover-transient ACK to a mobility management entity when the qualified user equipment accesses the wireless local area network; and releasing a bearer resource of the qualified user equipment when the MME receives the handover-transient ACK, retaining bearer information of the qualified user equipment, and handing over the qualified user equipment from the cellular network to the wireless local area network.
