Embodiment

Below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.

LTE network is when frequency planning for third generation partner program (3GPP, 3rd Generation Partnership Project), and can adopt a kind of networking plan being called frequency shift channeling, its main thought is:

Total utilized bandwidth can be divided into N (N >=2) individual subband, and this N number of subband has lap or completely orthogonal between any two, and the bandwidth of this N number of subband is identical or different;

For each subband of this N number of subband, find subband that associated property is larger and the less subband of correlation.The size of the correlation of so-called intersubband, refers to that the frequency of two intersubbands coincidences accounts for the scale of the frequency sum of two subbands.The frequency of two subband coincidences is more, and the correlation represented between them is larger; Vice versa;

The minimum principle of the correlation of the subband used according to making neighbor cell, to the cell allocation subband in network, is specially: subband less for correlation is given adjacent sector respectively, subband larger for correlation is given respectively sector relatively far apart.

In order to be illustrated more clearly in the main thought of frequency shift channeling networking plan, provide an example below:

Fig. 2 is the frequency planning schematic diagram adopting frequency shift channeling networking plan, as shown in Figure 2, suppose that available bandwidth is 30MHz, whole available bandwidth 30MHz is divided into 3 subbands according to aforementioned principle, and each subband is 20MHz, and partly overlaps between subband between two, then by the 20MHz allocation of subbands of left end to community A, by the 20MHz allocation of subbands of right-hand member to community B, by the 20MHz allocation of subbands of centre to community C, community A, B, C are three sectors of same site.

For frequency shift channeling networking plan, existing LTE MBMS mechanism is also inapplicable.

The present invention is directed to frequency shift frequency reuse networks and provide two kinds of MBMS transmission schemes:

Scheme one, base station using the MBSFN resource of the total frequency resource of all communities in self multicast broadcast single frequency network MBSFN region as this all community, and determine the MBMS form in this MBSFN transmitted over resources;

Base station is by MBSFN resource allocation information and the terminal send in MBSFN region all communities at the MBMS form of this MBSFN transmitted over resources in;

The MBMS of base station form described in described MBSFN transmitted over resources.

Scheme two, any M in the MBSFN region of base station is had to the community of total frequency resource, this base station is using the MBSFN resource of this total frequency resource as this M community, the MBSFN subset of resources of the MBSFN resource of this M community as MBSFN region is closed simultaneously, determine this MBSFN subset of resources close transmission MBMS form, wherein, 1≤M≤N, N is the community sum in the MBSFN region of this base station;

All configuration informations of MBSFN subset of resources conjunction in MBSFN region and the MBMS form of correspondence thereof are sent to the terminal in all communities in MBSFN region by base station;

For arbitrary community, the MBMS of the corresponding form of the MBSFN transmitted over resources of base station in this community.

MBMS transmission method flow diagram in the frequency shift frequency reuse networks that Fig. 3 provides for the embodiment of the present invention one, as shown in Figure 3, its concrete steps are as follows:

Step 301: for the arbitrary base station in frequency shift frequency reuse networks, the MBMS form in this MBSFN transmitted over resources using the MBSFN resource of the total frequency resource of all communities in self MBSFN region as this all community, and is determined in this base station.

Obviously, when MBSFN region is 1 community, the available frequency resources of this community is its MBSFN resource.

MBMS form is as the Modulation and Coding Scheme (MCS, Modulation and CodingScheme) of MBMS.

Step 302: base station is by MBSFN resource allocation information and the terminal send in MBSFN region all communities at the MBMS form of this MBSFN transmitted over resources in.

Wherein, MBSFN resource allocation information comprises: Physical Resource Block (PRB, the Physical Resource Block) index of MBSFN resource place frequency and/or MBSFN resource.

Base station by the following two kinds mode by MBSFN resource allocation information and the terminal send in MBSFN region all communities at the MBMS form of this MBSFN transmitted over resources in:

Mode one, pass through system broadcast message.

MBSFN resource allocation information and MBMS form are carried in system broadcast message the terminal in all communities be broadcast in MBSFN region by base station.

Mode two, by multicast control signal.

Now, base station needs first by cell system broadcast the position of multicast control channel (MCCH, Multicast Control Channel) or amendment advice position to be broadcast to the terminal in all communities in MBSFN region; Then, MBSFN resource allocation information and MBMS form are carried in multicast control signal and send to the terminal in all communities by corresponding MCCH by base station.Wherein, the position of MCCH comprises: MCCH place frequency, MCCH revise cycle, MCCH repetition period, MCCH place subframe position, and MCCH amendment advice position comprises: the number of repetition of the transmission frequency of MCCH amendment advice, the delivery time of MCCH amendment advice, MCCH amendment advice.

Step 303: terminal receives MBSFN resource allocation information and the MBMS form in this MBSFN transmitted over resources.

Step 304: base station is at MBSFN transmitted over resources MBMS, and terminal receives this MBMS in MBSFN resource.

For arbitrary community, there are two kinds of processing methods to its frequency resource except MBSFN resource: 1) on the shelf; 2) use to non-MBSFN user.

MBMS transmission method flow diagram in the frequency shift frequency reuse networks that Fig. 4 provides for the embodiment of the present invention two, as shown in Figure 4, its concrete steps are as follows:

Step 401: for the arbitrary base station in frequency shift frequency reuse networks, for any M (1≤M≤N) the individual community with total frequency resource in the MBSFN region of this base station, the MBSFN subset of resources of the MBSFN resource of this M community as MBSFN region, using the MBSFN resource of this total frequency resource as this M community, is closed by this base station simultaneously.Wherein, N is the community sum in the MBSFN region of this base station.

Step 402: close for the arbitrary MBSFN subset of resources in MBSFN region, determines to close in this MBSFN subset of resources the MBMS form of transmission in base station.

As N=1, when namely MBSFN region is 1 community, the available frequency resources of this community is the MBSFN resource of this community.

For the ZhongNGe community, MBSFN region of base station, this N number of community possible has total frequency resource; Also total frequency resource may be had in the cell portion in this N number of community; Also may have total frequency resource in this N number of community, the cell portion simultaneously in this N number of community has total frequency resource.No matter belong to which kind of situation, for any M (1≤M≤N) the individual community with total frequency resource, can using the MBSFN resource of this total frequency resource as this M community, this M community can use the MBMS that this MBSFN resource transmission is identical.

Can find out, the MBSFN subset of resources that may comprise multiple incomplete overlap in a MBSFN region is closed.Different MBS FN subset of resources is closed and can be transmitted identical MBMS, also can transmit different MBMS.Such as: if there is m1 (1 < m1 < N) individual community to have total frequency resource Fx in N number of community, in addition, m2 (1 < m2 < N) individual community is had to have total frequency resource Fy, wherein, Fx and Fy is not exclusively overlapping, then Fx can be used as the MBSFN resource of an aforementioned m1 community, Fy can be used as the MBSFN resource of an aforementioned m2 community, and the MBMS of the upper transmission of Fx and Fy can be identical, also can be different, Fx, Fy are that the MBSFN subset of resources in MBSFN region is closed.

, also can find out, for arbitrary community, it may have the MBSFN subset of resources of multiple incomplete overlap to close meanwhile.

Step 403: the configuration information that each MBSFN subset of resources is closed by base station and the terminal in all communities that the MBMS form that this MBSFN subset of resources closes transmission sends in MBSFN region.

The configuration information that MBSFN subset of resources is closed comprises: MBSFN subset of resources closes the PRB index of place frequency and/or the conjunction of MBSFN subset of resources.

Particularly, base station is by the configuration information that each MBSFN subset of resources closed with under type and the terminal in this MBSFN subset of resources closes all communities that the MBMS form of transmission sends in MBSFN region:

Mode one, pass through system broadcast message.The configuration information that each MBSFN subset of resources is closed by base station and this MBSFN subset of resources close transmission MBMS form be carried in system broadcast message the terminal be broadcast in all communities.

Mode two, by multicast control signal.Specific as follows:

First, the position or amendment advice position that issue the MCCH that multicast control signal uses, by system broadcast message, are broadcast to the terminal in all communities in MBSFN region by base station.Wherein, the position of MCCH comprises: MCCH place frequency, MCCH revise cycle, MCCH repetition period, MCCH place subframe position, and MCCH amendment advice position comprises: the number of repetition of the transmission frequency of MCCH amendment advice, the delivery time of MCCH amendment advice, MCCH amendment advice.

Then, base station configuration information that each MBSFN subset of resources is closed and be carried in multicast control signal terminal in all communities sent to by corresponding MCCH in MBSFN region at the close MBMS form of transmission of this MBSFN subset of resources.

Here, it should be noted that, if all MBSFN subset of resources in MBSFN region are closed, the MBMS of transmission is identical, then base station only can use a MCCH, now, carry configuration information and this MBMS form of the conjunction of all MBSFN subset of resources in multicast control signal, like this, the terminal in all communities can receive same multicast control signal on same MCCH.

If all MBSFN subset of resources in MBSFN region are closed, the MBMS of transmission is different, then base station only can use a MCCH, now, the configuration information of all MBSFN subset of resources conjunction and the MBMS form of correspondence thereof is carried in multicast control signal, like this, the terminal in all communities can receive same multicast control signal on same MCCH; Or, base station can use many MCCH, the configuration information that every bar MCCH closes for the MBSFN subset of resources transmitting a MBMS form and this MBMS form of all uses, namely, the number of MCCH is identical with the number of MBMS form, like this, each community can receive many multicast control signals on many MCCH.

Step 404: for the arbitrary community in MBSFN region, when base station will to this cell transmission one MBMS time, in each MBSFN subset of resources of this community is closed, search the MBSFN subset of resources can transmitting this MBMS form close, close in this MBMS subset of resources and transmit this MBMS.

A community may have multiple MBSFN subset of resources and close, and each MBSFN subset of resources closes the MBMS transmitted may identical also possibility difference.

Any terminal in step 405:MBSFN region is closed from this MBSFN subset of resources and is received MBMS.

For any terminal in MBSFN region, it can close from the arbitrary MBSFN subset of resources MBSFN region and receive MBMS.
