Description
Technical field
The present invention relates to the method and apparatus in wireless communication system, more particularly in cellular network system
MBMS (Multimedia Broadcast Multicast Service, multi-medium multi-packet broadcasting multicast
Service) business transmission method and device.
Background technology
Traditional third generation cooperative partner program (3GPP-3rd Generation Partner
Project) in Long Term Evolution (LTE-Long Term Evolution) system, define
MBSFN (Multimedia Broadcast Single Frequency Network, multicast and broadcast
Single Frequency Network) subframe (abbreviation M subframes).In traditional 3GPP versions, a system-frame (System
Frame) include 10 subframes (Subframe), numbering be #0, #1, #2, #3, #4, #5,
#6, #7, #8, #9 }, in these subframes, it is contemplated that ensure the biography of the system messages such as broadcast message
It is defeated, by taking FDD (Frequency Division Duplex, frequency division multiplexing) pattern as an example, only
{ #1, #2, #3, #6, #7, #8 } is configurable to M subframes.
M subframes are mainly used in transmitting MBMS.In traditional 3GPP versions, in M subframes,
