Below in conjunction with Fig. 1 several basic conceptions relevant with MBMS in the LTE system are described.
The MBSFN(multicast single-frequency network) transmission: refer to carry out synchronous transmission with same frequency in a plurality of residential quarters at one time.Use this transmission means can save frequency resource, improve the availability of frequency spectrum.
MBSFN retaining zone: refer to all eNode(evolution base stations) all can obtain synchronously and the zone of carrying out the MBSFN transmission.
The MBSFN zone sends/the announcement residential quarter: refer to the class residential quarter in the MBSFN zone, such residential quarter had both participated in MBSFN and had sent the announcement that also participates in MBSFN transmission availability in the residential quarter.
MBSFN zone sends the residential quarter: refer to the class residential quarter in the MBSFN zone, such residential quarter only participates in MBSFN and sends and do not participate in the announcement that the MBSFN residential quarter in transmits availability.
The MBSFN zone keeps the residential quarter: refer to the class residential quarter in the MBSFN zone, it does not participate in MBSFN and sends.
The MBMS transmission can be divided into many cell transmission and single cell transmission, and many cell transmission adopt the MBSFN transmission, and single cell transmission employing PTM(is point-to-multipoint) transmission.The residential quarter that is used for the MBMS transmission is divided into MBMS dedicated cell and MBMS/ clean culture mixed cell, in the MBMS dedicated cell, and a MBMS transmission business, and in MBMS/ clean culture mixed cell, existing MBMS is professional, and unicast service is also arranged, and the two transmits with cooperative mode.
EMBMS need to transmit by corresponding logic channel and transmission channel.Logic channel is the access controls of MAC(media) layer definition and interface upper-layer protocol, MAC provides data transmission service for logic channel, and logical channel type is used for distinguishing the type of data transmission service.Transmission channel is that physical layer is to layer 2(such as MAC layer) interface that is used for the transmission of data that provides, the type of transmission channel defines according to transmission feature and the transmission means of data on physical layer.In addition, also defined physical channel in physical layer, employed running time-frequency resource and coded system etc. when being used for showing transfer of data.
