Described resource indication information can comprise the resource indication of frequency domain, and/or the indication of the resource of time domain.When a plurality of multicast broadcasting service areas territory is divided when multiplexing at an enterprising line frequency of subframe, the frequency resource indication is used to notify each multicast broadcasting service area territory of terminal employed frequency resource scope in subframe.On time domain, different multicast broadcasting service area territories can take identical or different subframe, or radio frames, or superframe.Control station can notify terminal each multicast broadcasting service area territory scope of resource on time domain by the time-domain resource indication.

On the multiplexing carrier wave of Multimedia Broadcast Multicast Service and unicast service, the Resource Unit that is used for Multimedia Broadcast Multicast Service in the subframe on one or more frequency partition is that unit and described continuous logical resource unit shine upon one by one with Resource Block or resource subband.The mapping process of Resource Unit and continuous logical resource unit is:

If there is frequency partition 0 in system, then: at first, is that granularity is mapped as described continuous logical resource unit in order successively with the one or more subband resource type unit (Subband LRU is called for short SLRU) that are used for Multimedia Broadcast Multicast Service in the frequency partition 0 with the subband;

Again with

frequency partition

1,2, the one or more SLRU that are used for Multimedia Broadcast Multicast Service in 3 are that granularity is mapped as follow-up continuous logic Resource Unit in order successively with the subband.

If only there is

frequency partition

1,2,3 in system, then: with

frequency partition

1,2, the one or more SLRU that are used for Multimedia Broadcast Multicast Service in 3 are that granularity is mapped as continuous logical resource unit in order successively with the subband.

Particularly,

frequency partition

0,1, the sub band resources on 2,3 (Subband is called for short SB) is mapped to continuous sub band resources (contiguous subband is called for short CSB) two kinds of mapping modes.

First kind of mapping mode

At first the sub band resources with the multicast broadcasting service area territory of distributing on the subregion 0 is mapped on the continuous sub band resources, the sub band resources of then on the subregion 1 all being distributed to the multicast broadcasting service area territory is mapped on the continuous sub band resources, the rest may be inferred, again with subregion 2, the sub band resources that in 3 all are distributed to the multicast broadcasting service area territory is mapped on the continuous sub band resources, is mapped on the continuous sub band resources up to all sub band resources of distributing to the multicast broadcasting service area territory.

The concrete enforcement of this first kind of mapping mode can be referring to the mapping mode among Fig. 5,6,8.

Suppose that N represents the resource total quantity (is unit with the subband) in multicast broadcasting service area territory; N _FPn(n is 0～3) represents

subregion

0,1 respectively, the resource quantity in multicast broadcasting service area territory on 2,3; SB _FPi(j) represent sub band resources in any subregion, wherein, i represents partition number (value is respectively 0,1,2,3), and j represents the subband numbering in each subregion.

SB _FPi(j) be mapped on the continuous sub band resources CSB, its corresponding sub band resources is CSB (k), and wherein k can calculate by following formula (1):

Wherein, N _FP0Be employed number of sub-bands in the subregion 0, can know by the number of sub-bands parameter of subregion in the system parameters 0.

If only there are

frequency partition

1,2,3, then N in system _FP0Be 0, k can calculate by following formula (2):

k = j + Σ_{n = 0}^{i - 1} N_{FPn}, i > 0 - - - (2)

Wherein, N _{FPi, i＞0}Be employed number of sub-bands in the

subregion

1,2,3, can calculate respectively:

N _FP3＝N-N _FP0-N _FP1-N _FP2 (5)

If resource on the subregion 0 is only used in the multicast broadcasting service area territory, then k can calculate by following formula: k=j, promptly this moment i=0.

In this first kind of mapping mode, according to top described formula (1) to (5) as can be known, the subband SB in the subregion 0 _FP0(j) shine upon

subregion

1,2, the subband SB in 3 with CSB (j) one by one _FPi(j) with

Mapping one by one.

Second kind of mapping mode

At first the sub band resources with all distribution on the subregion 0 is mapped on the continuous sub band resources, then with

subregion

1,2, a sub band resources on 3 is mapped to respectively on the continuous sub band resources, again with

subregion

1,2, the sub band resources of getting respectively on 3 is mapped on the continuous sub band resources, the rest may be inferred, all is mapped on the continuous sub band resources up to all sub band resources of distributing to the multicast broadcasting service area territory.Promptly at every turn from

subregion

1,2, get one or more sub band resources on 3 and shine upon, intact up to whole mappings.

The concrete enforcement of this second kind of mapping mode can be referring to the mapping mode among Fig. 4,7,9.

Suppose that N represents the resource total quantity (is unit with the subband) in multicast broadcasting service area territory; N _FP0Represent the resource quantity in multicast broadcasting service area territory on the subregion 0.SB _FPi(j) represent sub band resources in any subregion, wherein, i represents partition number (value is respectively 0,1,2,3), and j represents the subband numbering in each subregion.

SB _FPi(j) be mapped on the continuous sub band resources CSB, its corresponding sub band resources is CSB (k), and wherein k can calculate with following formula (6):

N wherein _FP0For employed number of sub-bands in the subregion 0, can know by system parameters.

If only there are

frequency partition

1,2,3, then N in system _FP0Be 0, k can calculate by following formula (7):

k＝i+3*j，i＞0 (7)

If the resource on the subregion 0 is only used in the multicast broadcasting service area territory, then k can calculate by following formula: k=j, i=0 at this moment.

Top formula shows, the subband SB in the subregion 0 _FP0(j) shine upon one by one with CSB (j), when subregion 0,

subregion

1,2, the subband SB in 3 _FPi(j) with CSB (i+3*j+N _FP0-1) mapping one by one; When no subregion 0,

subregion

1,2, the subband SB in 3 _FPi(j) shine upon one by one with CSB (i+3*j).

Among the present invention, described continuous logical resource unit CSB further can form one or more Resource Unit subclass, and each Resource Unit subclass comprises one or more continuous logical resource unit.

When the index building space, can adopt tree to represent index space, wherein: each logical resource unit is corresponding one by one with leaf node on the described index space; Described Resource Unit subclass be that intermediate node on the described index space is corresponding one by one; Described Resource Unit complete or collected works be that root node on the described index space is corresponding.

Suppose each node be designated node (i, j), wherein, i represents row, leaf node is the 0th row, j represents row, every capable Far Left node is the 0th row, then node (i, j) the capable j of expression i row.I+1 can represent the quantity of the subband that distributed, and j then represents to begin to distribute from subband CSB (j).Node node (i, j) the index k of representative and node (i, relation j) can calculate with formula (8):

k(i，j)＝(i+j)*(i+j+1)/2+i； (8)

Control station is that each multicast broadcasting service area territory sends resource index k to terminal, and terminal calculates according to resource index then that (i j), thereby obtains the quantity allotted and the positional information of subband.According to the mapping relations of resource subband in aforesaid subband and each frequency partition, obtain resource location and the quantity information of multicast broadcasting service area territory in each frequency partition again.

When the index building space, also can adopt question blank (look-up table) structure to represent index space, wherein:

Each logical resource unit is a first order subclass, with (i is 0 for i, j) expression, and p is from 0 to N-1, successively with begin with the unit corresponding from index of zero on the described question blank;

The subclass that is made of two continuous Resource Units is a second level subclass, with (i is 1 for i, j) expression, and p is from 0 to N-i-1, successively be that follow-up unit on the described question blank is corresponding;

The rest may be inferred, and described Resource Unit complete or collected works are N level subclass, with (i is N-1 for i, j) expression, and p is 0, and is corresponding with last unit on the described question blank.

The first kind of mapping mode that adopts the question blank mode is referring to shown in Figure 6, and the second kind of mapping mode that adopts the question blank mode is referring to shown in Figure 7.

m (i, j) = Σ_{k = 0}^{i} (N - k + 1) + j - - - (9)

Wherein, the i span is 0～(N-1), and the j span is 0～(N-i-1).I+1 can represent the quantity of the subband that distributed, and j then represents to begin to distribute from subband CSB (j).

Control station is that each multicast broadcasting service area territory sends resource index m to terminal, and terminal calculates according to resource index then that (i j), thereby obtains the quantity allotted and the positional information of subband.According to the mapping relations of resource subband in aforementioned subband and each frequency partition, obtain the position and the quantity information of the sub band resources of multicast broadcasting service area territory in each frequency partition again.

Among the present invention, can also be by described continuous logical resource unit CSB be indicated the resource location and the quantity information in each multicast broadcasting service area territory in the mode of bit map (bitmap).Whether each bit of described bit map is used to indicate affiliated multicast broadcasting service area territory, two adjacent sub band resources unit to change, promptly whether belong to same multicast broadcasting service area territory, the size of bit map, i.e. number of bits is for the sum of sub band resources unit subtracts 1.If the quantity of sub band resources unit is 8, then the figure place of bit map is 7.

For example, the bit of bit map belongs to same multicast broadcasting service area territory for two adjacent sub band resources unit of " 0 " expression, and the bit of bit map belongs to different multicast broadcasting service area territories for two adjacent sub band resources unit of " 1 " expression.The quantity of " 1 " adds 1 number of promptly representing the multicast broadcasting service area territory in the bit map.
