Resource acquiring method embodiment
In order to realize the compatibility of 16e and 16m system, on the basis of the 16e system of having set up, realize the uplink service service of 16m system terminal, should guarantee that the running time-frequency resource that the 16m system terminal uses does not conflict mutually with the already used running time-frequency resource of the terminal of 16e system, it is interference-free that the running time-frequency resource that is to say the original distribution of terminal normal use that should guarantee the 16e system carries out upstream data service, and the terminal that will realize the 16m system 16e system that yet can use other does not have the running time-frequency resource that uses, last data service.Field information will be carried in the base station of 16m system in assignment message when being terminal assignments running time-frequency resource in the native system, this field information is used to identify first system and second system takies running time-frequency resource; Terminal receives the resource allocating message that is used to distribute running time-frequency resource that the base station of first system sends, and described resource allocating message carries and is used to the field information that first system that identifies and second system take running time-frequency resource; According to the described field information that receives, in the running time-frequency resource of described base station assigns, obtain spendable running time-frequency resource.The 16m system is first system in the embodiment of the invention, and the 16e system is second system.Particularly, the terminal that belongs to the 16m system receives the resource allocating message that the native system base station sends, comprise not only that in described resource allocating message the base station is the time-frequency standing breath of this terminal distribution, but also carry a field information, terminal just can obtain the shared running time-frequency resource information of 16e system or two systems by this field information according to the resource allocation mapping mode of system, terminal is obtaining under the situation of base station for the resource of its distribution and the resource that system takies, and can be to find actual operable running time-frequency resource in the resource of its distribution in the base station just.Certainly the embodiment of the invention also can be applicable to the situation of many each systems, promptly except that the 16m system at terminal place, also comprise a plurality of other systems, when the base station issues the field information of identifying resource distribution condition, can be the running time-frequency resource information that other system takies except that the 16m system that issues, also can issue the field information that is used to identify the running time-frequency resource information that all systems of comprising the 16m system take.
Fig. 1 is resource acquiring method embodiment one flow chart of the present invention, as shown in Figure 1, comprises the steps:
The base station of 16m system sends the ascending resource assignation message be used to described terminal distribution running time-frequency resource to the terminal that belongs to this system, and described ascending resource assignation message carries the offset field information that is used to identify the logic running time-frequency resource that the 16e system uses.
The base station is in the time of the terminal distribution running time-frequency resource, because the mode of the frequency domain resource of 16e system and 16m system mapping is different, caused in the base station of 16m system is the running time-frequency resource of terminal distribution, may existing the part frequency domain resource shared by the 16e system, use the same frequency resource to carry out upstream data service for fear of 16e system and 16m system occurring, conflict and produce, when therefore the base station of 16m system is the terminal distribution running time-frequency resource, also to notify this terminal 16e system to use how many logic running time-frequency resources, described logic running time-frequency resource is meant in certain frequency domain bandwidth divides some spots, every bit has been represented the subcarrier on the physical significance, a plurality of subcarriers are dispersed in the logical meaning subchannel of creating of starting from scratch, and each subchannel has just been represented a logic running time-frequency resource.On behalf of the 16e system, offset field used which logical sub-channel, and the physical sub-carrier of the distribution in already used subchannel has also just been used by the 16e system so.
After step 101, terminal receive described ascending resource assignation message, obtain the running time-frequency resource of 16e system use according to the subcarrier mapping mode of 16e system according to described offset field information;
In terminal from the described ascending resource assignation message that receives, both can obtain the base station and be used to carry out the employed running time-frequency resource of upstream data service for its distribution, can obtain the already used running time-frequency resource information of 16e system according to the offset field information that ascending resource assignation message is carried again, be specially, on the terminal of 16m system, store frequency domain resource mapping mode information in advance about the 16e system, terminal is after receiving the offset field information that is used to identify the logic running time-frequency resource that the 16e system uses, can calculate in the logical sub-channel of offset field message identification the already used physical sub-carrier information of 16e system according to the frequency domain resource mapping mode of 16e system.
Terminal is under the situation that calculates the already used subcarrier of 16e system, in the base station is to remove the already used sub-carrier resources of 16e system in the running time-frequency resource of its distribution, just can obtain the actual operable sub-carrier resources of terminal, guarantee not clash with the 16e system.
Fig. 2 is resource acquiring method embodiment one signaling process figure of the present invention, as shown in Figure 2, comprising:
Step a1, the base station of 16m system sends ascending resource assignation message to terminal, carries the offset field information that is used to identify the logic running time-frequency resource that the 16e system uses in this message;
Step b1, terminal is according to described offset field information, calculates the already used running time-frequency resource of 16e system according to the resource mapping method of the 16e system of storage in advance;
Step c1, terminal is the running time-frequency resource of its distribution according to already used running time-frequency resource of 16e system that calculates and base station, obtains actual spendable running time-frequency resource;
Steps d 1, terminal utilize the spendable running time-frequency resource of described reality to send upstream message to the base station.
The actual spendable running time-frequency resource that terminal obtains is to have timeliness, and promptly certain subcarrier is to have the 16e system shared in a particular moment, but the 16e system does not take this subcarrier always, other constantly the 16e system do not take this subcarrier; The terminal of the 16m system sub-carrier resources that also can use the 16e system not take so in a particular moment.Among the above embodiment, when the subcarrier mapping mode of 16e system is when partly or entirely using subcarrier, the base station sends the offset field information be used to identify the logic running time-frequency resource that the 16e system uses to terminal, and the form that adds the resource offset field in assignment message is as shown in table 1.
