Embodiment
In actual applications, expanding packet is containing the structure of multi-carrier resource indication information in advance, to after the network side multi-carrier resource that has been terminal distribution, can multi-carrier resource indication information be set and send to terminal for the multi-carrier resource distributing for terminal; Like this, the multi-carrier resource that terminal just can be indicated according to received multi-carrier resource indication information is realized communication.
Can apply various ways in advance expanding packet containing the structure of multi-carrier resource indication information, as:
First kind of way
On the basis of existing control information IE (as: the A-MAP IE in Wimax 16m standard), add two kinds of IE types: descending this distribution of protecting group information element (DL Guard Basic Assignment IE) and up this distribution of protecting group information element (UL Guard Basic Assignment IE), be used to indicate GLRU.Generally speaking; base station indicates whether to have protection subcarrier (multi-carrier resource) binding to use to certain scheduling of resource for certain terminal by IE type; if for example IE type is that DL/UL Guard BasicAssignment IE explanation has multi-carrier resource to distribute to current scheduling of resource, if DL/UL BasicAssignment IE explanation does not have.The distribution condition (may comprise and whether use conventional system resource) that represents conventional system resource with the indication information Resource Index in IE content.How indication information Guard Resource Index indication in IE content distributes multi-carrier resource, while being 0bit such as the length as Guard Resource Index, representing does not have signaling Guard Resource Index only according to IE type, to judge whether multi-carrier resource in IE content; When the length of Guard Resource Index is 1bit, represent to represent whether there is multi-carrier resource by the Guard Resource Index of 1 bit; When the length of Guard Resource Index is 2bit, expression is used the Guard Resource Index of 2bit to represent the distribution condition of multi-carrier resource, base station can be divided into two parts by multi-carrier resource, indicates respectively wherein every a multi-carrier resource whether to distribute to terminal.Terminal determines according to first bit of Guard Resource Index whether the multi-carrier resource of first distributes to this terminal, according to second bit of Guard Resource Index, determines whether the multi-carrier resource of second portion distributes to this terminal.
The second way
Signaling (as: the DL Basic AssignmentIE in Wimax 16m system and the UL Basic Assignment IE) content that special indexed resource is distributed is added, the new signaling content indication GLRU adding of application.
When applying above-mentioned first kind of way, can define two kinds of A-MAP IE:Guard DL BasicAssignment IE and Guard UL Basic Assignment IE, be all specifically designed to the distribution of indicating downlink and up GLRU resource.The content comprising in above-mentioned IE at least comprises one of following or combination: IE type, GLRU resource location indication information Guard Resource Index that IE is corresponding, CRC check position etc.The concrete structure of GuardDL Basic Assignment IE and Guard UL Basic Assignment IE is respectively as shown in table 1.1 and table 1.2:

If comprise CRC check position in Guard DL Basic Assignment IE and Guard UL Basic Assignment IE, so conventionally, can the content in IE generate, and CRC check position and station designator (Station Identitier, STID) can form mask.
A-MAP IE is the indication how base station notification terminal operates.Base station can, for the multi-carrier resource distributing for terminal, arrange multi-carrier resource indication information Guard Resource Index; And this Guard Resource Index is carried in corresponding Guard DL Basic Assignment IE and Guard ULBasic Assignment IE and sends to terminal.When terminal is received after Guard DL Basic Assignment IE or Guard UL Basic Assignment IE, just can parse the GuardResource Index comprising in IE, and apply the indicated multi-carrier resource of this Guard Resource Index and realize communication.
While being 1bit such as the Guard Resource Index length of receiving when terminal, Guard ResourceIndex=1 represents that all multicarriers bind to this terminal, and Guard Resource Index=0 represents not have multicarrier to bind to this terminal.
Such as when Guard Resource Index length is 2bit, base station can be divided into two parts by multi-carrier resource again, indicates respectively wherein every a multi-carrier resource whether to distribute to terminal.Terminal determines according to first bit of GuardResource Index whether the multi-carrier resource of first distributes to this terminal, according to second bit of Guard Resource Index, determines whether the multi-carrier resource of second portion distributes to this terminal.Afterwards, terminal can be applied the multi-carrier resource realization communication of distributing to self, as: for downlink data receiving, for sending upstream data etc.
When applying the above-mentioned second way, in the signaling (as: DL Basic Assignment IE and UL Basic Assignment IE etc.) that can distribute at existing special indexed resource, add Guard ResourceIndex.Add the DL Basic Assignment IE of Guard Resource Index and the concrete structure of UL BasicAssignment IE respectively as shown in table 2.1 and table 2.2:
