OPTIMIZATION OF MBSFN DECODING ON SCELLS WHEN THE PCELL AND SCELLS BELONG TO SAME MBSFN AREA

摘要

A mobile device determines that a primary cell (PCell) and a secondary cell (SCell) belong to a same multicast-broadcast single frequency network (MBSFN) area or that the PCell and the SCell can broadcast the same service. The mobile device determines a communication state of the SCell. If the SCell is active, the mobile device compares signal quality on the PCell and the SCell and selects to decode broadcast content on the PCell or the SCell. If the communication state indicating the SCell is deactivated or released, the mobile device switches to decode the broadcast content on the PCell. If the SCell is released and if the mobile device determines that the PCell is also released, then the mobile device switches to decode the broadcast content on the PCell and initiates a neighbor cell search.

1. A method of wireless communication, comprising:
determining, by a mobile device, at least one of that a primary cell (PCell) and a secondary cell (SCell) belong to a same multicast-broadcast single frequency network (MBSFN) area, or that the PCell and the SCell can broadcast a same service; determining, by the mobile device, a communication state of the PCell and the SCell; selecting, by the mobile device, to decode broadcast content on one of: the PCell, or the SCell, based on a comparison of signal quality on the PCell and the SCell, wherein the selecting is in response to the communication state indicating the SCell is active; switching, by the mobile device, to decode the broadcast content on the PCell in response to the communication state indicating the SCell is one of: deactivated or released; and in response to the communication state indicating that the SCell is released and that the PCell is released:
switching, by the mobile device, to decode the broadcast content on the PCell, andinitiating, by the mobile device, a neighbor cell search.
