Description
Technical field
The present invention relates to field of wireless communication, particularly the receiving/transmission method of multimedia broadcasting and multicast service in the TDS-CDMA system (TD-SCDMA).
Background technology
Along with the fast development of Internet and popularizing of large-screen multi-functional mobile phone, a large amount of mobile data multimedia services emerge, various high bandwidth multimedia services constantly occur, as video conference, television broadcasting, video request program, advertisement, online education, interactive game etc., satisfy the business demand that the mobile subscriber constantly rises on the one hand, also bring new business growth point simultaneously for mobile operator.These mobile multi-media services require a plurality of users can receive identical data simultaneously, compare with general data, have characteristics such as data volume is big, longer duration, delay sensitive.
In order to effectively utilize mobile network resource, third generation partner program (3rd GenerationPartnership Project, abbreviation 3GPP) multimedia broadcasting and multicast service (MultimediaBroadcast Multicast Service have been proposed, be called for short MBMS), this business is a kind of technology that transmits data from a data source to a plurality of targets, thereby realize sharing of network (comprising core net and Access Network) resource, improve the utilance of Internet resources (especially air interface resource).The MBMS of 3GPP definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the broadcasting and the multicast of high-speed multimedia business, multiple rich video, audio frequency and multimedia service are provided, this has complied with the trend of following mobile data development undoubtedly, for the development of 3G provides better professional prospect.
The configuration of the professional radio bearer of MBMS can be adopted the bearer types of P-T-M (put multiple spot, also can write a Chinese character in simplified form PTM or ptm) and P-T-P (point-to-point also can be write a Chinese character in simplified form PTP or ptp).The PTM mode of MBMS business uses common logical MTCH (MBMS PTM Traffic Channel, MBMS point multipoint message traffic channel) that all are added multicast service or the interested UE of broadcasting service is sent data; The MTCH logic channel is mapped to transmission channel FACH (Forward Access Channel, forward access channel), by physical channel Secondary CCPCH (Secondary CommonControl Physical Channel, less important Common Control Physical Channel is called for short SCCPCH) send at wave point.System side RNC (radio network controller) informs the configuration informations such as physical channel of the relevant MBMS business configuration of UE by MCCH (MBMSpoint-to-multipoint Control Channel, the MBMS point is to the multiple spot control channel) channel.
The MBMS related news of the last transmission of MCCH comprise: MBMS Access Information (MBMS access information), MBMS Common p-t-m rb Information (the public point to multi-point wireless beared information of MBMS), MBMS Current Cell p-t-m rb Information (MBMS current area P-T-M wireless loading information), MBMS General Information (MBMS general information), MBMS Modified services Information (MBMS revises business information), MBMSUnmodified services Information (MBMS does not revise business information) or the like.
UTRAN carries out the relevant system information broadcast of MBMS in system message (SIB5 and SIB5bis), comprise MBMS PTM control channel (MCCH:MBMS point-to-multipoint ControlChannel) configuration information.
Can there be serious co-channel interference when in the TD-SCDMA multi-carrier frequency system, providing MBMS professional.Logic channel MTCH under the MBMS PTM mode is mapped to transmission channel FACH, and finally is carried on public physic channel SCCPCH.Because public physic channel SCCPCH uses omni-directional antenna transmission, and because MBMS business at a high speed mobile TV service normally takies many code channels.Therefore, when using the SCCPCH channel of omni-directional antenna transmission to carry out the continuous covering of MBMS business, can cause the co-channel interference of serious minizone, make service quality can not get ensureing in many sub-districts.
The problem of co-channel interference of minizone during for the solution identical networking, a kind of well accepted scheme is single-slot network (Uniform Timeslot Network, a UTN) technology.Require all neighbor cells to use same carrier, time slot, channel code, scrambler and basic midamble (training sequence) sign indicating number when sending the wireless signal of same MBMS business channels based on this technology, at a time on the crack, different districts sends after all adopting identical scrambler to the wireless signal scrambling, UE can be considered as multipath signal with the signal that comes from different base station when receiving, UE can obtain bigger performance gain after the multipath signal that receives is carried out multipath merging processing.Simultaneously, the UTN networking technology can be avoided the neighbor cell problem of co-channel interference in the TD-SCDMA system.
In existing 3G wireless network networking, the cell scrambling that disposes between the neighbor cell is different in twos, so that UE is according to the wireless signal of different scrambler differences from different districts.And the UTN mode sends wireless signal, requires neighbor cell to send the professional wireless signal of identical MBMS on identical frequency, time slot.This is different from the UTN scrambler of cell scrambling with regard to requiring system to the time slot configuration that sends the MBMS service signal.Like this, network side carries out scrambling with the UTN scrambler to the professional wireless signal of MBMS and handles having disposed on the frequency time slot of UTN, and the time slot that does not dispose UTN is used cell scrambling.UE receives wireless signal having disposed on the frequency time slot of UTN, uses the UTN scrambler of network configuration to carry out scramble process, and uses cell scrambling not disposing on the frequency time slot of UTN.But in existing 3GPP agreement, do not have definition how in the TD-SCDMA system, to dispose the needed UTN scrambling code information on specific frequency time slot of UTN, thereby can't carry out the MBMS data transmit-receive of UTN mode.
