Use SC-PTM modes in art, which send MBMS, causes the problem of user can not obtain diversity gain and cause co-channel interference,
This programme proposes concretely comprising the following steps with the sending method for broadcasting the MBMS that SC-PTM schemes, i.e. the present embodiment are provided：
S101：Determine that the same of the first MBMS broadcasts region and configuration information.
In the present embodiment, it is described to be made up of some adjacent cells with broadcasting region；The configuration information includes：Described
The same of one MBMS broadcasts subframe, the Physical Downlink Shared Channel of first MBMS is sent in subframe with broadcasting described
(English：Phyisical Downlink Shared Channel, referred to as：PDSCH) the first bandwidth taken, the first coding is adjusted
Method processed；This is the descending sub frame for sending the first above-mentioned MBMS, the first bandwidth that the PDSCH takes with subframe is broadcast
Indicate some continuous resource block (English that the PDSCH takes：Resource Block, referred to as：RB).
Optionally, a kind of specific acquisition is with the mode for broadcasting region：Obtain every in the MBMS region to be sent
The user distribution situation of individual cell；To together it be broadcast as described including the user and adjacent cell that can receive the MBMS
Region.That is MCE (or other network elements) can often go out according to the distribution situation of user or the estimated distribution situation of user in user
Existing some neighbor cells set the same of the business to broadcast region.
S102：The ID and the configuration information of first MBMS are sent to described each small in region with broadcasting
Area.
In this step, MCE or other network elements can be got for being somebody's turn to do at this with transmission in region is broadcast as needed
, it is necessary to which the mark of the configuration information and the first MBMS to be sent is (English after the configuration information of MBMS：
Identity, referred to as：ID this) is broadcast to each cell broadcast in region.
S103：First MBMS is sent by PDSCH according to the ID and the configuration information of first MBMS
Business.
In the present embodiment, for a MBMS, used in the same region of broadcasting of the MBMS with broadcasting SC-PTM modes
The business is sent, i.e.,：Same asset and modulation coding method (English are used with each cell broadcast in region：Modulation
Coding Scheme, referred to as：MCS identical MBMS) is sent, according to above-mentioned configuration information, by PDSCH, son is broadcast same
On the continuous RB that frame and the first bandwidth are indicated, the first MBMS is sent using the first code modulating method, this is broadcast together
User in region results in diversity gain, and at this, broadcast the moving between cells in region does not result in business datum to user together
Interruption and discarding.
For not being the same cell broadcast in region, such as：There are some cells being sporadicly distributed of user, each cell is still
It is old that MBMS is sent by existing SC-PTM modes, i.e.,：By cell decide in its sole discretion send the business use running time-frequency resource and
MCS。
The sending method for the MBMS that the present embodiment is provided, by determining to send MBMS in certain region
With region is broadcast, the MBMS of identical first is sent using identical configuration information with each cell broadcast in region to this,
MBMS is sent using SC-PTM modes so that this can be divided with the user broadcast in region with the region broadcast outside region
Diversity gain, and co-channel interference can be avoided.
Drawn to realize in such scheme, this programme with broadcasting region, with broadcasting subframe and with broadcasting bandwidth (i.e. above-mentioned first
It is bandwidth, identical with the implication of the first bandwidth with bandwidth is broadcast in follow-up scheme) concept.It is above-mentioned several in SC-PTM is broadcast together
Concept is applied when being sent in descending MBMS, wherein, it is made up of with region is broadcast adjacent some cells, can in these cells
To send identical business by identical interface-free resources and MCS, the user in these cells is obtained diversity gain, keep away
Exempt from co-channel interference.In subframe is broadcast together, whole bandwidth is divided into what each MBMS sent to broadcast SC-PTM modes together took
It is same to broadcast bandwidth and common bandwidth.Same bandwidth some resource blocks in whole bandwidth of broadcasting of each MBMS are constituted.Common bandwidth
Other remaining RB are constituted in whole bandwidth.When to the distribution of each MBMS with bandwidth is broadcast, each MBMS industry can be made
It is engaged in being connected before and after the RB of occupancy, such as：Same broadcast is distributed since the minimum RB of whole bandwidth to each MBMS in sequence
Bandwidth, such MBMS takes one section of bandwidth of whole frequency band low side by concentrating, and remaining bandwidth can make to other business
With being so assigned and avoid causing resource fragmentation in whole bandwidth with broadcasting bandwidth, be conducive to the resource allocation of other business.
In the specific implementation, can root with the number for broadcasting subframe and the same same size for broadcasting bandwidth for broadcasting MBMS in subframe
According to estimated with the speed determination for broadcasting the MBMS that SC-PTM modes are sent in cell.Such as, every kind of service rate is used
MCS, take resource block number and be generally pre-configured with dispatching cycle.
Also, to make to obtain diversity gain with the user for broadcasting region, it is whole with the cell broadcast in region at one with broadcasting son
The same of frame broadcasts the same transmission block for sending same business in bandwidth using identical MCS, that is, sends identical business datum.Send
Physical Downlink Shared Channel (the English of the business：Phyisical Downlink Shared Channel, referred to as：PDSCH) exist
With broadcast subframe it is same broadcast the reference signal that resource unit mapping mode and demodulation are based in bandwidth will differ from it is non-with broadcasting son
The PDSCH of frame in, also different from the PDSCH broadcast in subframe in common bandwidth.
In this scenario, i.e., it can be designed specifically to the frame structure for broadcasting SC-PTM：
Normal cyclic prefix (English is supported with SC-PTM is broadcast：Normal Cyclic Prefix, referred to as：NCP) and extension
Cyclic prefix (English：Extended Cyclic Prefix, referred to as：ECP the existing subframe structure under)：Each subframe is by controlling
Domain and data field are constituted.
The number of symbols that control domain takes in each subframe is by Physical Control Format Indicator Channel (English：Physicial
Contorl Format Indicator Channel, referred to as：PCFICH) indicate
Data field is divided into：The same of each MBMS occupancy broadcasts bandwidth and common bandwidth.The RB that each MBMS takes
Constitute the same of the MBMS and broadcast bandwidth；Other RB constitute common bandwidth.The physical channel and data field that control domain is sent are sent
Physical channel compared with agreement.
(1), control domain：
Control domain supports cell reference signals (English：Cell-specific Reference Signal, referred to as：CRS),
For control channel (PCFICH/PHICH/PDCCH) demodulation；
Control domain physical channel and CRS resource unit (English：Resource Element, referred to as：RE co-occurrence) is mapped
There is agreement.
(2), data field
Physical channel and reference signal (English that existing protocol is supported are supported in common bandwidth：Reference Signal,
Referred to as：RS), these channels and RS RE are mapped compared with agreement；
Only support to send the MBMS with broadcasting under SC-PTM in bandwidth with broadcasting, business is sent by PDSCH, same to broadcast bandwidth
RS used in interior PDSCH RE mappings and PDSCH demodulation needs to redefine.
More preferably to support with SC-PTM is broadcast, support in a radio frames except following subframe there must be phase with subframe 0
Same CP types and length, other subframes are configurable to the CP types different from subframe 0.The configuration information passes through system information
Block (English：System Information Block are referred to as：SIB) it is broadcast to UE.
(1) time division duplex (Time Division Duplex, TDD)：Subframe 1, subframe 5 and 6；
(2) FDD (Frequency Division Duplex, FDD)：Subframe 5
In TDD, subframe 1 and subframe 6 include master sync signal, and subframe 0 and subframe 5 include auxiliary synchronous signals.The usual roots of UE
CP types are determined according to TS0/TS5 auxiliary synchronous signals and TS1/TS6 master sync signal.Therefore, subframe 1,5 and 6 should be with son
Frame 0 has identical CP length.For FDD, subframe 0 and subframe 5 include master sync signal and auxiliary synchronous signals, therefore, and subframe 5 should
There should be identical CP with subframe 0.
Based on above-mentioned, several sides of implementing for obtaining the first running time-frequency resource and the first coded system etc. are described below
Formula：
First way, obtains the antenna port number and physical layer that CRS is sent with each cell broadcast in region
Cell ID；Determine configuration information when implementing, in addition it is also necessary to obtain this and send CRS's with each cell broadcast in region
Antenna port number and physical-layer cell identifier.Being implemented as first MBMS is sent according to the configuration information：Institute
State and first MBMS is sent by PDSCH with broadcasting subframe；Wherein, in first bandwidth instruction at least one is continuous
In RB, the PDSCH is mapped on the resource unit being not take up with the CRS for broadcasting each cell in region.
Its implication is：The CRS of each cell is being broadcasted in bandwidth with broadcasting, these CRS solutions are based on PDSCH in bandwidth is broadcast
Adjust, PDSCH is mapped to the resource unit (English that these cells CRS is not take up：Resource Element, referred to as：RE on).It is negative
Duty determines the same MCE for broadcasting region by with the antenna port number and physical-layer cell identifier for broadcasting each cell transmission CRS in region
(English：Identifier, referred to as：ID) notify to give each cell.Each cell can determine each cell CRS according to the information
The RE of occupancy, PDSCH avoid these RE when mapping.CRS time-domain position is decided by transmission CRS antenna port number, CRS's
Frequency domain position is decided by the value of physical-layer cell ID moulds 6.Therefore, the CRS of each cell is avoided, it is necessary to will to map PDSCH
Notify small to each with the antenna port number and physical-layer cell ID (or ID MOD 6) for broadcasting each cell transmission CRS in region
Area.
Use this kind of design, it is not necessary to redesign with broadcast the demodulation of PDSCH in bandwidth based on RS, old UE (do not prop up
Hold with broadcasting SC-PTM UE) measurement based on CRS is unaffected, and the non-of new, old UE can be dispatched in common bandwidth
MBMS.
The second way, obtains the antenna port number and thing that CRS occupancy is sent with each cell broadcast in region
Manage layer mark；Determine configuration information when implementing, in addition it is also necessary to obtain this and send CRS's with each cell broadcast in region
Antenna port number and physical-layer cell identifier.Then passed through according to the ID and the configuration information of first MBMS
PDSCH, which sends first MBMS, to be included：Institute is configured at least one continuous RB that first bandwidth is indicated
State the same of PDSCH demodulation and broadcast reference signal；
First MBMS is sent described with broadcasting subframe by PDSCH, and sends institute while PDSCH is sent
State and broadcast reference signal together；Wherein, it is described described to be not take up with the CRS for broadcasting each cell in region with broadcasting reference signal and be mapped to
Resource unit on；The PDSCH is mapped to the CRS with each cell broadcast in region and described equal with reference signal is broadcast
On unappropriated resource unit.
Its implication is：Demodulated to solve to broadcast together channel estimation in bandwidth in first way with PDSCH by co-channel interference
The problem of, which is (English with reference signal is broadcast with design in bandwidth is broadcast：Reference Signal, referred to as：RS) it is used for
PDSCH demodulation.It is mapped to RS is broadcast on the RE that non-CRS takes.PDSCH is mapped to CRS and broadcast on the RE that RS is not take up together.Tool
Body, the CRS of each cell is still being broadcasted in bandwidth with broadcasting, to support to dispatch old UE in common bandwidth；Design is same to broadcast band
The special RS of PDSCH demodulation in wide：With RS is broadcast, these RS are mapped on the RE that non-CRS takes；PDSCH is mapped to these cells
CRS and with broadcasting on the RE that RS is not take up.It is responsible for determining the same MCE for broadcasting region by with the antenna for broadcasting each cell transmission CRS in region
Port number and physical-layer cell ID notify to give each cell.Each cell can determine that each cell CRS is accounted for according to the information
RE, these RE are avoided with when broadcasting RS and PDSCH mappings.
Using this kind of design, measurements of the old UE based on CRS is unaffected, and can be dispatched in common bandwidth
Newly, old UE；Introduce with broadcasting RS, make with broadcasting in bandwidth the channel estimation of group user and PDSCH demodulation not by the shadow of co-channel interference
Ring.
The third mode, different from above two mode, the configuration information also includes：First indicates, described first refers to
Show and do not sent at least one continuous RB that first bandwidth is indicated for indicating described with broadcasting each cell in region
CRS；The first MBMS bag is then sent by PDSCH according to the ID and the configuration information of first MBMS
Include：The same of PDSCH demodulation is configured at least one continuous RB that first bandwidth is indicated and broadcasts reference signal；
First MBMS is sent described with broadcasting subframe by PDSCH, and sends institute while PDSCH is sent
State and broadcast reference signal together；Wherein, the PDSCH is mapped to described with broadcasting on the unappropriated resource unit of reference signal.
Its implication is：Above two mode with broadcast retain in bandwidth each cell CRS so that old UE measurement not by
Influence, can dispatch old UE in common bandwidth.But, but cause pilot tone to take RE excessive.The third mode is broadcast for raising is same
Pilot efficiency in bandwidth, using following scheme：The CRS of each cell is not being broadcasted in bandwidth with broadcasting；Design is same to be broadcast in bandwidth
The special RS of PDSCH demodulation：It is same to broadcast RS；PDSCH is mapped to same broadcast on the RE that RS is not take up.
The advantage of which：Do not support CRS to broadcast with broadcasting in bandwidth, greatly reduce number of pilots, improve effect of eating dishes without rice or wine
Rate；Introduce and broadcasts RS together, make to broadcast together the channel estimation of user and PDSCH demodulation in bandwidth is not influenceed by co-channel interference；Without MCE
The antenna port number and physical-layer cell ID that each cell is sent into CRS notify to give each cell.
In each above-mentioned implementation, only when all users are supported with SC-PTM is broadcast in a MBMS,
The business could be being dispatched in bandwidth with same broadcast for broadcasting subframe.
Used in above-mentioned second and the third mode with RS is broadcast, RS can be broadcast according to the generation of following three kinds of methods is same.
（1）RS is broadcast using the generation of CRS formula is same
On the RB that business takes RS is broadcast according to CRS generation formula generation the same of business：It is interim using business wireless network
Mark（English：Radio Network Temporay Identifier, RNTI）It is same to broadcast in region instead of physical-layer cell ID
It is identical with RS is broadcast that each cell is sent.In the case where the business is group service, business RNTI is exactly group RNTI.
Specifically, generation is same according to the following formula broadcasts RS sequences
In above formula, nsFor the timeslot number in a radio frames；L is the orthogonal frequency division multiplexi in time slot（English：
Orthogonal Frequency Division Multiplexing, referred to as：OFDM）Symbolic number；For
Maximum downstream bandwidth；Pseudo-random sequence c (i) initiation parameter cinitGenerate according to the following formula, nRNTIFor the RNTI of business.
cinit=210·(7·(ns+1)+l+1)·(2·nRNTI+1)+2·nRNTI+NCP
It is as follows with the mapping for broadcasting RS to RE：
In above formula,
K=6m+ (v+vshift)mod6
V and vshiftIt is defined as follows：
vshift=nRNTIMod6,The RB numbers taken for business, i.e. the first bandwidth or with broadcasting bandwidth.
In scheme two, to avoid the CRS of cell and being mapped to RS is broadcast on identical RE, l+lshift, lshiftBy MCE
1 or 2 is configured to, or is fixed as 1 or 2.
P span is decided by MCE.When MCE determines to send with RS antenna port number is broadcast for P, p<P.In reality
Border is sent with when broadcasting RS, can be sent using the transmission of single antenna port or multi-antenna port.
When single antenna port is sent, even if P>1, according to above-mentioned formula be mapped on different port it is same broadcast RS pass through it is same
RE on individual antenna port 0 on relevant position is sent.When multi-antenna port is sent, P>1, the same of different antennae port broadcasts RS difference
Sent by corresponding port.
(2) RS is broadcast using the generation of UE RS formula is same
On the RB that business takes RS is broadcast according to the special RS generations formula generations of UE are same.
Specifically, generation is same according to the following formula broadcasts RS sequences
In above formula, nsFor the timeslot number in a radio frames；The RB numbers taken for business；Pseudo-random sequence c
(i) initiation parameter cinitGenerate according to the following formula, nRNTIFor the RNTI of business,, can also to broadcast the ID in region together
It is fixed as 0.
It is as follows with the mapping for broadcasting RS to RE：
Normal cyclic prefix:
Extended cyclic prefix:
In above formula, m' is the same counter for broadcasting RS in an OFDM symbol,P=0.
(3) RS is broadcast using the generation of MBSFN RS formula is same
On the PRB that business takes RS is broadcast according to MBSFN RS generation formula generations are same：MBSFN areas are substituted using traffic ID
Domain IDSpecifically, it is same to broadcast RS sequencesIt is defined as follows：
In above formula, nsFor the timeslot number in a radio frames；L is the OFDM symbol number in time slot；For
Maximum downstream bandwidth；Pseudo-random sequence c (i) initiation parameter cinitGenerate according to the following formula, nRNTIFor the RNTI of business.
cinit=29·(7·(ns+1)+l+1)·(2·nRNTI+1)+nRNTI
It is as follows with the mapping for broadcasting RS to RE：
In above formula, p=0,
In above formula,The RB numbers taken for business.
, it is necessary to which following information is notified to new UE in above-mentioned the first and the second way：
With antenna port number and physical-layer cell ID (or the physical-layer cell ID for broadcasting the transmission of each cell region in CRS
Mould 6)
In the inventive solutions, support to need reporting ability to network with the UE for broadcasting SC-PTM.Above-mentioned
In three kinds of modes, for not supporting with the old UE for broadcasting SC-PTM, if measurements of the old UE based on CRS is broadcast bandwidth without CRS's by same
Influence be can not ignore, when network use with broadcast SC-PTM when, by existing protocol using with broadcast SC-PTM occupancy subframe as
MBSFN sub-frame is notified to old UE., will by SIB when network is used with SC-PTM is broadcast for supporting with the new UE for broadcasting SC-PTM
With the subframe and the same RB range notifications for broadcasting bandwidth occupancy for broadcasting SC-PTM occupancy to new UE.New UE believes in these subframes according to scheduling
Breath receives physical channel and the same MBMS broadcast in bandwidth in common bandwidth.When had been friends in the past in a MBMS UE when, should
Business can not be used and is scheduled with broadcasting bandwidth.
PDSCH uses individual layer to be sent in the way of single antenna port or transmitting diversity.Mapped with PDSCH in bandwidth is broadcast in RE
When only take up the RE that non-RS is used.
If PDSCH supports transmitting diversity, it is necessary to which each cell reports the port number for sending CRS, MCE broadcasts area according to same
The cell of minimum CRS port numbers determines to send PDSCH port number in domain.Indicate that each cell carries out Dan Tian with the number
Line is sent or transmitting diversity is sent.
When PDSCH is scrambled, the initiation parameter c of scramble sequenceinitGenerate according to the following formula：
In above formula, nRNTIIt is the RNTI of group when business is group service for business RNTI；G-RNTI；q∈{0,1}
Code word 0 and code word 1, when single codeword is sent, q=0 are corresponded to respectively；For with broadcasting region ID or be fixed as 0.MCE can be with
Different ID are distributed to different same regions of broadcasting.
PDSCH resource allocation supports TYPE2 resource distribution mode.CSI is not supported to report and confirm (English：
Acknowledgement, referred to as：ACK)/deny (English：Non-acknowledgement, referred to as：NACK) feed back.
Technical scheme is proposed with SC-PTM schemes are broadcast, if neighbor cell all sends same business, those are small
Area is defined as broadcasting region together, and sends identical business using identical interface-free resources and MCS in these cells, and such user is connecing
Diversity gain is obtained with during receipts business, movement of the user between these cells does not result in the interruption of business datum and lost
Words.Also, in the specific implementation, network can be supported to broadcast SC-PTM UE together and do not propped up in the common bandwidth scheduling for broadcasting subframe together
Hold with the UE for broadcasting SC-PTM, while realizing that MBMS shares whole bandwidth with general service, user can obtain diversity increasing
Benefit, lifts spectrum efficiency.
