Embodiment

The present invention is directed to the multicarrier applicable cases and proposed a kind of resource allocation method, take into account narrow-band user and broadband user simultaneously, also take into account single carrier mode, discontinuous frequency spectrum multi-carrier mode and continuous frequency spectrum multi-carrier mode simultaneously.

As shown in Figure 5, broad band multicarrier resource allocation method of the present invention may further comprise the steps:

Step 501, base station are that mobile phone users is provided with the basic resources configuration information;

Above-mentioned basic resources configuration information comprises: use multicarrier still be single carrier mode, each carrier wave centre frequency and bandwidth information, whether use protection bandwidth and other and multicarrier relevant information.

Step 502, portable terminal be by carrying out up-downgoing synchronously and after reading broadcast message with the base station, works on the main carrier that the base station is provided with and obtain user's basic resources configuration information;

When portable terminal used the single carrier mode, this main carrier promptly referred to this single carrier; When the user used multi-carrier mode, this main carrier referred to a carrier wave in the multicarrier, specifically also depended on the initial selection situation that inserts of terminal searching by the base station configuration decision.

Step 503: terminal judges that the user uses single carrier mode or multi-carrier mode, if single carrier mode then forwards step 504 to, if multi-carrier mode then forwards step 505 to by user's basic resources configuration information;

Step 504, portable terminal obtains the uplink and downlink running time-frequency resource by the detailed resource allocation information of main carrier, and flow process finishes;

Portable terminal carries out data communication by the above-mentioned uplink and downlink running time-frequency resource and the base station that obtain.

Step 505, the terminal use judges whether to use the protection bandwidth according to the basic resources configuration information, if forward step 506 to, if not, forwards step 508 to;

Step 506 is obtained the running time-frequency resource that each carrier wave uplink and downlink can be used by the detailed resource allocation information of each carrier wave (comprising main carrier), obtains available protection bandwidth running time-frequency resource by protection bandwidth indication information;

Described protection bandwidth is arranged in the protection portions of bandwidth in the middle of two adjacent carriers of multicarrier that portable terminal takies under the continuous frequency spectrum multi-carrier mode.

Step 507, the running time-frequency resource that converges each carrier wave running time-frequency resource and protect bandwidth; Flow process finishes.

Herein; portable terminal according to each carrier information (as centre frequency; bandwidth) and protection bandwidth indication information, the running time-frequency resource of each carrier wave running time-frequency resource and protection bandwidth is carried out polymerization, carry out transfer of data between these running time-frequency resources and base station so that portable terminal uses.

The running time-frequency resource that converges each carrier wave running time-frequency resource and protection bandwidth herein is meant the operation of using a plurality of running time-frequency resources simultaneously, can be regarded as the operation of mapping (enum) data on a plurality of carrier waves simultaneously.

Step 508 is obtained the running time-frequency resource that each carrier wave of uplink and downlink can be used by the detailed resource allocation information of each carrier wave (comprising main carrier);

Step 509 converges the running time-frequency resource of each carrier wave; Flow process finishes.

In above-mentioned steps 504,506, in 508, the detailed resource allocation information of main carrier, the detailed resource allocation information of each carrier wave and protection bandwidth indication information dynamically change at system's signal intelligence with terminal and base station in service.

If the multicarrier number that a certain portable terminal uses when adopting multi-carrier mode is two, because of service needed need increase a carrier wave, in said method, the base station does not need to change the corresponding information of original two carrier waves in the basic resources configuration information, only need to increase the information of a new carrier wave, improved the expandability of broad band multicarrier.

Among the present invention, for multicarrier system, no matter wide-band terminal still is a narrowband terminal can be obtained the basic resources configuration information by main carrier; Order is used the wide-band terminal of continuous frequency spectrum and discontinuous frequency spectrum multicarrier and is used the narrowband terminal of single carrier wave to obtain maximum consistency in resource distribution.

Need use the multicarrier situation of protecting bandwidth for the user, this user can use the running time-frequency resource of protecting the adjacent low frequency carrier signal of bandwidth therewith simultaneously.As shown in Figure 6, use the multicarrier user who protects bandwidth 1 can use the running time-frequency resource of uplink and downlink corresponding in the carrier wave 1 simultaneously, make spendable frequency spectrum resource keep continuity.

As shown in Figure 6, DL (descending indication information), UL (up indication information) and DL_g (protection bandwidth indication information) difference indication carrier wave 1 descending, up and protection bandwidth 1 running time-frequency resource in the carrier wave 1; DL in the carrier wave 2 (descending indication information), UL (up indication information) and DL_g (protection bandwidth indication information) be indication carrier wave 2 descending, up and protection bandwidth 2 running time-frequency resources respectively; Carrier wave 3DL (descending indication information), UL (up indication information) be indication carrier wave 3 descending, uplink time respectively.

Under the situation that does not deviate from spirit of the present invention and essence thereof, those of ordinary skill in the art are when making various corresponding changes and distortion according to the present invention, and these change and be out of shape the protection range that all should belong to the appended claim of the present invention accordingly.
