Description
Technical Field
The present invention relates to a method and an apparatus in a wireless communication system, and more particularly, to a method and an apparatus for transmitting an MBMS (Multimedia Multicast Service) Service in a cellular network system.
Background
In a conventional 3GPP-3rd Generation partnership Project (3GPP-3rd Generation Partner Project) Long Term Evolution (LTE-Long Term Evolution) system, an MBSFN (multicast Broadcast Single Frequency Network) subframe (M subframe for short) is defined. In the conventional 3GPP release, a System Frame (System Frame) includes 10 subframes (Subframe) numbered as { #0, #1, #2, #3, #4, #5, #6, #7, #8, #9}, and only { #1, #2, #3, #6, #7, #8} of the subframes can be configured as M subframes in an FDD (Frequency Division Duplex) mode as an example in view of guaranteeing transmission of System messages such as broadcast information.
The M subframes are mainly used for transmitting MBMS services. In the conventional 3GPP release, the broadcast multicast traffic cannot be multiplexed with other unicast traffic in the M subframe.
In 3GPP RAN plenum #71 conference, enhanced embmbs (enhanced MBMS service) is listed as Release 14 new WI (Work Item), wherein an important aspect is to use all subframes in a system frame as M subframes and provide MBMS service.
Disclosure of Invention
In the conventional LTE system, in order to ensure transmission of key information such as system information and paging signals, the following information is transmitted and received on non-M subframes:
-PSS (Primary Synchronization Signal );
-SSS (Secondary Synchronization Signal);
-PBCH (Physical Broadcast Channel);
-SIBx (System Information block x), where x is a positive integer no less than 1 and no greater than 20, corresponding to 20 System Information blocks in the current LTE System;
-Paging signal;
when all subframes in one system frame are used for MBMS service transmission, the transmission of the above channel needs to be redesigned. The inventors have further investigated that one possible solution is that when a given subframe is used for both the above-mentioned critical information and MBMS service transmission, the MBMS service may be punctured while retaining the transmission of the critical information. However, this method obviously causes the degradation of the receiving performance corresponding to the MBMS service. Another possible approach is to still reserve part of the sub-frame for transmission of MBMS services. However, this reduces the total number of resources used to transmit MBMS services in the system, and is not desirable for the enhanced embmbs.
The present invention provides a solution to the above problems. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
