Embodiment
To be the base station compile accessing terminal of a plurality of real time business to core concept of the present invention is a group, and be this group reservation portion of time-frequency resource, and the base station is that unit is for accessing terminal and Resources allocation with the group.
Specifically comprise the steps:
1, the base station is one " a resource group " with the volume that accesses terminal of a plurality of startup real time business under the same sector.
Certainly, a plurality of " resource groups " can be set up in the base station under same sector, in order to distinguish each " resource group ", for each " resource group " distributes one " group number ".
2, in " resource group ", each " location number " in group of distribution that accesses terminal that the base station is.
Accessing terminal in " resource group " takies the interior resource of group by " location number " size order.
3, set aside some time-frequency resource for " resource group " in the base station.
4, the base station uses " group resource allocation " message to be all Resources allocation that access terminal in " resource group ", accesses terminal and receive the data that the base station sends on time corresponding-frequency resource.
Include " access terminal and whether exist " indication and " resource size " indication in " group resource allocation " message, whether be included as the resource that certain accesses terminal and distributes in this message of " access terminal and whether exist " indication expression; This message of " resource size " indication expression is certain resource size that accesses terminal and distribute.
The present invention will be further described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, be the structure chart of " resource group " in the OFDMA of the present invention system, there are 4 in should " resource group " and access terminal that (AT1～AT4), 4 " location numbers " that access terminal in group are respectively 1～4, and the group number of this " resource group " is GroupID1.
As shown in Figure 2, be " group resource allocation " message structure figure in the OFDMA of the present invention system, " access terminal and whether exist " indicating bit of 4 bits is arranged, respectively corresponding A T1～AT4 in should " group resource allocation " message.In this example, the bit of AT1, AT2 and AT4 correspondence is " 1 ", expression should comprise the resource of distributing to AT1, AT2 and AT4 in " group resource allocation " message, and the bit of AT3 correspondence is " 0 ", and expression should not comprise the resource of distributing to AT3 in " group resource allocation " message.
Be somebody's turn to do " resource size " indicating bit that 8 bits are arranged in " group resource allocation " message, corresponding 2 bits of each AT.In this example, the value of 2 bits of AT1 correspondence is that should " group resource allocation " distribution of messages to give the resource size of AT1 be 1 unit in 1 expression, the value of 2 bits of AT2 correspondence is that should " group resource allocation " distribution of messages to give the resource size of AT2 be 2 units in 2 expressions, the value of 2 bits of AT4 correspondence is 3, and it is 3 units that this " group resource allocation " distribution of messages of expression is given the resource size of AT4.
As shown in Figure 3, for AT in the OFDMA of the present invention system adds resource group and group resource allocation and process chart, in this example, accessing terminal is the AT4 among Fig. 2.
In this message, " group number " of " resource group " that base station notice AT4 adds is GroupID1, and the location number of AT4 in " resource group " is 4.
After step 304, base station are received resource bid message, be the AT4 Resources allocation, and structure " group resource allocation message ";
AT4 learns the existence of AT1, AT2 from " group resource allocation " message, and has taken 1,2 resource units respectively, therefore, AT4 can calculate distribute to oneself resource since the 4th, and take 3 resource units (with reference to Fig. 2 example).
