In order to help the understanding of the present invention, below some concepts occurred are done to explain herein:
Activate: a carrier wave is a mobile terminal activating, mean that this mobile terminal has been assigned with the Radio Resource be positioned on this carrier wave, correspondingly, it is that the state of a mobile terminal activating then means that network management device distributes to the Radio Resource be on this carrier wave of this mobile terminal before having regained that carrier wave is no longer in, after this, this carrier wave is just in inactive (deactivated) state relative to this mobile terminal.
Independent Carrier Wave and dependent carrier wave: herein, the carrier wave in the carrier component that can be access in independently is called Independent Carrier Wave, and the carrier wave in the carrier component that can not be access in independently is called dependent carrier wave.It will be appreciated by those skilled in the art that above, Independent Carrier Wave is not limited to the carrier wave in backward compatibility carrier component, non-backward compatible carrier waves component, but not Independent Carrier Wave is also not limited to the carrier wave in stand alone carrier component.For LTEA system, multiple carrier wave can be comprised in whole radio band, and 1 in these carrier waves to multiple carrier wave belongs to Independent Carrier Wave, and other 1 belongs to dependent carrier wave to multiple carrier wave.Thought of the present invention is not by the impact of concrete carrier wave dividing mode.In the present invention, a typical example of dependent carrier wave is exactly the carrier wave of stand alone carrier component self not bearer control signalling this.
First quantity and the second quantity: the value of the first quantity above can be more than or equal to 1 integer.
Terminal iidentification: in order to carry out upstream or downstream communication, a mobile terminal needs to be assigned with terminal iidentification, like this, according to the resource allocation information indicated by terminal iidentification, mobile terminal will be known and use the such as concrete frequency of what kind of Radio Resource, time slot or pseudo-code etc. to communicate with network management device.In order to effectively distinguish the information of different terminals in up, downlink information, different mobile terminals should be assigned with the terminal iidentification of inequality on same carrier wave.Unlikely conflict ground, between different carrier, the terminal iidentification of mobile terminal can be multiplexing.

Embodiment
As shown in Figure 1, the multiple mobile terminals in community are administered in base station 1 to typical application scenarios of the present invention, for simplicity's sake mobile terminal 21-23 are only shown in figure.Under network shown in Fig. 1 is operated in multicarrier environment particularly, define 4 carrier waves as shown in Figure 2 without loss of generality, wherein, carrier wave A is between frequency f 1 and f2, carrier wave B is between frequency f 2 and f3, and carrier wave C is between frequency f 3 and f4, and carrier wave D is between frequency f 4 and f5.Number of carriers in Fig. 2 should not be understood as that limiting the scope of the invention, and in practical application of the present invention, the carrier wave that base station may be used for arranging can be more, or less, such as three.Importantly, in prior art, the existing division to carrier wave can be applied to the present invention easily.
Without loss of generality, the base station 1 in this example and mobile terminal 21-23 belong to LTEA system, and further, carrier wave A, B in definition Fig. 2 belong to backward compatibility carrier component, and carrier wave C belongs to non-backward compatible component, and carrier wave D belongs to stand alone carrier component.So carrier wave A, B and C are just Independent Carrier Wave in this example, also claim Independent Carrier Wave A, B and C below, carrier wave D is dependent carrier wave, also claims dependent carrier wave D below.
After having understood applicable scene of the present invention, introduce method provided by the present invention in conjunction with flow chart in detail.Fig. 3 a show according to a specific embodiment of the present invention in multi-carrier systems for the treatment of the systems approach flow chart communicated between network management device with mobile terminal, wherein, with reference to Fig. 1,2 and main base station 1 for wherein and mobile terminal 21.
Shown in Fig. 3 a, flow process starts from step S11, and wherein, in Stochastic accessing (random access) process, the first quantity Independent Carrier Wave is activated for mobile terminal 21 in base station 1.Here, the quantity of the Independent Carrier Wave of activation depends on the resource requirement of mobile terminal 21 and the dividing mode of carrier wave.According to a specific embodiment of the present invention, a carrier wave A can be activated for mobile terminal 21 in base station 1 first, and when carrier wave A cannot meet the business demand of mobile terminal 21, then activate another carrier wave for it, such as carrier wave B.
As a result, in this example, in step S11, have activated Independent Carrier Wave A for mobile terminal 21.
So, in step S12, for mobile terminal 21 distributes the terminal iidentification corresponding with each Independent Carrier Wave, as shown in table 1, for the ease of comparing, the terminal iidentification distribution condition of another mobile terminal 23 is also illustrated in table 1:
Table 1: the terminal iidentification distribution condition of mobile terminal
Be not difficult to find out by table 1, the terminal iidentification corresponding to same Independent Carrier Wave that base station 1 is distributed for different mobile terminal is different.And for same mobile terminal, the terminal iidentification corresponding to different Independent Carrier Wave that base station 1 is distributed for it can be the same or different.In addition, if an Independent Carrier Wave is no longer certain mobile terminal activating, this mobile terminal 23 can discharge corresponding terminal iidentification, and this mark just can be assigned to the unlikely conflict as the terminal iidentification corresponding with this Independent Carrier Wave of other mobile terminal.
Although step S11 and step S12 is shown in Fig. 3 a for successively carrying out, but it will be appreciated by those skilled in the art that also can after activation Independent Carrier Wave, distribute corresponding terminal iidentification immediately, then activate next Independent Carrier Wave and distribute corresponding terminal iidentification.
For the mobile terminal 22 of a LTE terminal such as shown in Fig. 1, when have activated multiple Independent Carrier Wave such as carrier wave A, B for it, base station 1 is mobile terminal 22 distributing terminals mark, wherein, corresponding with carrier wave A terminal iidentification and the terminal iidentification corresponding with carrier wave B can be the same or different.
In mobile terminal 21 side, it correspondingly receives each terminal iidentification that base station 1 is sent, and particularly, the terminal iidentification assigning process shown in Fig. 3 a can be presented as RACH transmitting procedure that is existing in LTE system and that continued to use by LTEA system.
After mobile terminal 21 obtains the terminal iidentification 0001 corresponding with Independent Carrier Wave A, all information that this mark just can be used to send on Independent Carrier Wave A base station 1 carry out the series of physical layer process such as decoding, and this mark can be used to carry out the series of physical layer process such as coding to by all information issuing base station on Independent Carrier Wave A.Above-mentioned information comprises signaling, data etc. on PDCCH and PDSCH.
After this, the traffic carrying capacity of mobile terminal 21 strengthens, and only may be difficult to reply with Independent Carrier Wave A, causes the retardance of information and the rough sledding such as packet loss occur, so base station 1 is preferably further other carrier wave activated beyond Independent Carrier Wave A of mobile terminal 21.Wherein: different standards may be different for the selection of other carrier wave, such as, can adopt the activation sequence of frequency increments, or adopt the active mode of Stochastic choice, in addition, for the use of dependent carrier wave, can use when Independent Carrier Wave is used up, also can be not limited thereto.
In this example, without loss of generality, adopt the activation sequence of frequency increments, because the business demand amount of mobile terminal 21 continues to increase, frequency also activates for mobile terminal 21 in succession higher than Independent Carrier Wave B, C of Independent Carrier Wave A, and for this reason, base station 1 is assigned with corresponding terminal iidentification, terminal iidentification allocation result based on mobile terminal 23 does not change this hypothesis, and new terminal iidentification distribution condition is as shown in table 2:
Table 2: the terminal iidentification distribution condition of mobile terminal
Table 2 confirms in the present invention further, and the terminal iidentification corresponding to different carrier distributed for same mobile terminal can be the same or different.
In this example, base station 1 uses RRC signaling to send the terminal iidentification 0001 and 0010 corresponding with Independent Carrier Wave B, C, after receiving these two marks, mobile terminal 21 uses it for the process of the information of this mobile terminal on corresponding Independent Carrier Wave, and above-mentioned information comprises signaling, data etc. on PDCCH and PDSCH.
Step S13 is a determining step, and because of the difference of embodiment, the trigger condition of this step is distinguished to some extent.Such as, when carrier wave trigger sequence is frequency increments, due to without restrictively any, dependent carrier wave D frequency in Fig. 2 is the highest, therefore, only when all Independent Carrier Waves have been after mobile terminal 21 activates all, just likely activate it, therefore, the judgement in step S13 can be triggered execution after all Independent Carrier Waves have activated all again
Thus be conducive to the hardware resource saving base station 1 place; Differently, if carrier wave trigger sequence be random fashion or other cause the trigger unit of dependent carrier wave D can identical with Independent Carrier Wave time, step S13 just periodically performs after step s 11, when not satisfying condition,
Wait for a period of time or again judge at once.
No matter adopt which kind of trigger sequence, when base station 1 triggers the second quantity dependent carrier wave for mobile terminal 21, base station 1 can be that mobile terminal 21 distributes the terminal iidentification corresponding with these dependent carrier waves in step S14.In this example, the second quantity value is 1, it will be appreciated by those skilled in the art that if the quantity of dependent carrier wave is different from shown in Fig. 2, such as, has 3 more than, then the value of the second quantity herein can reach 3.
So after step s 14, the allocation result of terminal iidentification is as shown in table 3, wherein, suppose that the traffic needs of mobile terminal 23 also rises to some extent, base station 1 is also for it have activated dependent carrier wave D:
Table 3: the terminal iidentification distribution condition of mobile terminal
From table 3, identically with Independent Carrier Wave, the terminal iidentification corresponding to same dependent carrier wave for different mobile terminal distribution is preferably different.And for same mobile terminal, base station 1 for its distribute to correspond to Independent Carrier Wave A, B identical with the terminal iidentification of dependent carrier wave D, thus saved this resource of terminal iidentification.Certainly, it will be appreciated by those skilled in the art that if this resource of terminal iidentification is not in short supply, then the terminal iidentification corresponding to different carrier distributing to mobile terminal 21 also can be different.
After receiving the terminal iidentification 0001 corresponding with dependent carrier wave D, mobile terminal 21 can use this mark to process the information on dependent carrier wave D, such as, encode, decode and other physical layer operations.For LTEA system, first mobile terminal 21 utilizes to decode PDCCH with the Independent Carrier Wave terminal iidentification that such as Independent Carrier Wave A is corresponding of transmission PDCCH, thus find the Radio Resource of transmission PDSCH, then, mobile terminal 21 uses the terminal iidentification corresponding with the carrier wave at Radio Resource place transmitting PDSCH to decode PDSCH.
It is another deterministic process in step S15, wherein, base station 1, for being in as among each Independent Carrier Wave of mobile terminal 21 state of activation, dependent carrier wave, judges whether that at least one Independent Carrier Wave or dependent carrier wave are no longer in the state into mobile terminal 21 activates.The traffic carrying capacity of the reason that this thing happens mobile terminal 21 often declines, or mobile terminal 21 shutdown mode etc.Wherein, on basis shown in table 3, decline according to the traffic carrying capacity of mobile terminal 21 and the order that the carrier wave activated carries out deexcitation (deactivate) can be successively decreased by frequency, also can determining at random, etc., the present invention is not by the impact of its concrete mode.It will be appreciated by those skilled in the art that the existence considering dependent carrier wave, because it can not be accessed independently, therefore preferably by its preferential deexcitation, or consider its existence and ensure at least one Independent Carrier Wave existence being in state of activation all the time.
In this example, without loss of generality, be that mobile terminal 21 is by dependent carrier wave 21 deexcitation, so, in step s 16, base station 1 notifies the terminal iidentification 0001 corresponding with dependent carrier wave D that the release of mobile terminal notice distributes, and this notification procedure can use RRC signaling.After this, 0001 this terminal iidentification just can be assigned to other mobile terminal for dependent carrier wave D when unlikely interference/obscure.Certainly, if it is not used for dependent carrier wave D by other mobile terminal, and mobile terminal 21 after this there is the obvious rising of traffic carrying capacity in a certain moment, then again can distribute to it by 0001, if and now 0001 by another mobile terminal be used for dependent carrier wave D, can be then the terminal iidentification that mobile terminal 21 distributes other, not repeat.
Those skilled in the art understand, although after step S15, S16 being shown in step S13, S14 in Fig. 3 a, but, this does not represent only after have activated dependent carrier wave for mobile terminal 21, step S15 can be performed, in fact, after step s 12, even after step s 11, just can start to perform step S15.Different phase, the carrier wave that step S15 investigates is different, because the carrier wave activated for mobile terminal 21 in different phase is different.
In the embodiment that above composition graphs 3a introduces, after have activated the second quantity dependent channel for mobile terminal 21, base station 1 is that mobile terminal 21 distributes the terminal iidentification corresponding with these dependent channels.Below an alternative of this embodiment is introduced again.
In fig 3b, for part same or analogous with Fig. 3 a, represent with the Reference numeral identical with Fig. 3 a, repeat no more.Below discuss the step S17 being different from Fig. 3 a, should be appreciated that label size herein might not show to have strict sequencing between step in ground, this embodies within a context to some extent.
In this example, for the dependent carrier wave D activated for mobile terminal 21, base station 1 is not ad hoc that mobile terminal 21 distributes the terminal iidentification corresponding to dependent carrier wave D as Fig. 3 a step S14.Instead, the information processing of mobile terminal 21 on dependent carrier wave D is carried out based on the terminal iidentification corresponding with independent channel distributed before between base station 11 with mobile terminal 21.
For each dependent carrier wave activated for mobile terminal 21, the terminal iidentification corresponding with which Independent Carrier Wave distributed for mobile terminal 21 is used just to become a problem needing to solve.Typically, the terminal iidentification for processing the information of mobile terminal 21 on dependent carrier wave D corresponds to Independent Carrier Wave used when base station 1 sends the control signal corresponding with dependent carrier wave D to mobile terminal 21.More typically, the terminal iidentification for processing the information of mobile terminal 21 on dependent carrier wave D corresponds to Independent Carrier Wave used when base station 1 sends the resource allocation information corresponding with dependent carrier wave D to mobile terminal 21.Particularly, be operated under the scheme shown in Fig. 3 b, mobile terminal 21 have passed through setting in advance, it is made can successfully to coordinate base station 1 to perform the flow process shown in Fig. 3 b, in step S17, when mobile terminal 21 use and the Independent Carrier Wave terminal iidentification that such as Independent Carrier Wave A is corresponding decode PDCCH, find to be positioned at the Resourse Distribute on dependent carrier wave D, so mobile terminal 21 uses the terminal iidentification corresponding to Independent Carrier Wave A to decode to the PDSCH on dependent carrier wave D.
