Method one; On full allocation carriers and part allocation carriers, all send the auxilliary broadcast channel information of this carrier wave; Because the part allocation carriers is not used in terminal network and inserts, so the auxilliary broadcast channel information of part allocation carriers can only send other parameter informations outside the initial ranging parameter information relevant with the terminal access procedure, promptly compared with prior art; The auxilliary broadcast channel information that sends on the part allocation carriers has lacked unnecessary redundant information, has reduced the expense of system.
Method two; The part allocation carriers is not sent the auxilliary broadcast channel information of this carrier wave; But when the terminal need increase other part allocation carriers as auxilliary carrier wave, or when carrying out the conversion between the part allocation carriers, the auxilliary broadcast channel information of above-mentioned part allocation carriers will send to the terminal by the one or more full allocation carriers of support terminal work.The auxilliary broadcast channel information here can only comprise other parameter informations outside the initial ranging parameter information relevant with the terminal access procedure.
For example, the auxilliary broadcast message parameter relevant with initial ranging mainly comprises following parameter in the table 3:
Base station isotropic emission antenna power effective value (BS EIRP); Maximum EIR * the P of the isotropism received power that initial ranging base station (Basic Station is called for short BS) is located
IR, maxInitial (the Start of ranging codes group) of ranging code; Initial ranging is competed first rollback window (Ranging Backoff Start); Initial ranging is competed final rollback window (Ranging Backoff End); Up zero-time is with reference to (UL_initial_transmit_timing); Initial ranging number of codes (Initial rangingcodes); Initial ranging is (Initial ranging interval) at interval; Initial ranging zone (Initialranging region).
Alternatively; With table 3 is example; When on the part allocation carriers, sending the auxilliary broadcast channel information shown in the table 3; Can not send above-mentioned parameter; Just on the part allocation carriers, can only send the auxilliary broadcast channel information that comprises these two parameters of upstream data burst description (Uplink_burst_profile), uplink sub-carrier arrangement mode (UL subcarrier mode) and give the terminal; Perhaps the part allocation carriers is not sent the auxilliary broadcast channel information of this carrier wave, when the terminal need increase other part allocation carriers as auxilliary carrier wave, or when carrying out the conversion between the part allocation carriers, above-mentioned two parameters can send to the terminal through the one or more full allocation carriers of support terminal work.Clearly, adopt delivery plan of the present invention after, it is more reasonable that auxilliary broadcast channel information disposes the auxilliary broadcast channel information that carrier wave sends than part in the correlation technique, effectively reduced unnecessary information, reduced overhead.
Wherein, the base station sends to terminal with the mode of clean culture with other parameter informations outside the initial ranging parameter information relevant with the terminal access procedure in the auxilliary broadcast channel information on the part allocation carriers through full allocation carriers.
Perhaps; The base station sends to terminal with the mode of multicast with other parameter informations outside the initial ranging parameter information relevant with the terminal access procedure in the above-mentioned auxilliary broadcast channel information through full allocation carriers; Just the base station can have identical full allocation carriers and need the identical part allocation carriers of activation to a plurality of, and the auxilliary broadcast channel information of this part allocation carriers is sent at the terminal that perhaps is transformed into identical part allocation carriers.
Perhaps; The base station sends to terminal with the mode of broadcasting with other parameter informations outside the initial ranging parameter information relevant with the terminal access procedure in the above-mentioned auxilliary broadcast channel information through full allocation carriers; And taking the mode of unicast as the auxilliary carrier wave of terminal indicating target, the terminal is finally according to the complete information of above-mentioned information acquisition target secondary carrier.
Device embodiment two
In the present embodiment; A kind of terminal is provided; Be used for receiving the main broadcast channel information of the full allocation carriers that the sending method of said method embodiment sends and the auxilliary broadcast channel information of auxilliary broadcast channel information and part allocation carriers, as shown in Figure 3, be the block diagram at this terminal; Comprise: first receiver module 30, second receiver module 32, describe this two modules in detail below in conjunction with Fig. 3.
Can know that by last description the broadcast message according on each different allocation carriers of reasonable disposition multicarrier system makes that the redundant information on the carrier wave has reduced, and has reduced the expense of system, has improved the performance of system.
In sum; The present invention inserts relevant broadcast message (wherein comprising the initial ranging parameter information relevant with the terminal access procedure) through reasonable disposition on a plurality of carrier waves in multicarrier system and terminal; Just main broadcast channel information and the auxilliary broadcast channel information with full allocation carriers sends to the terminal; And other parameter informations outside the initial ranging parameter information relevant with the terminal access procedure send to the terminal in the auxilliary broadcast channel information with the part allocation carriers; Perhaps other parameter informations outside the initial ranging parameter information relevant with the terminal access procedure are given the terminal in the auxilliary broadcast channel information of base station through full allocation carriers transmitting section allocation carriers; Solved in the correlation technique owing to inserting relevant broadcast message is sent the overhead increase that causes simultaneously on a plurality of carrier waves problem with the terminal; The present invention reduces overhead, and then has improved systematic function through reducing the redundant information of sending on the carrier wave.
Obviously, it is apparent to those skilled in the art that above-mentioned each module of the present invention or each step can realize with the general calculation device; They can concentrate on the single calculation element; Perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element; Thereby; Can they be stored in the storage device and carry out, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize by calculation element.Like this, the present invention is not restricted to any specific hardware and software combination.
