A method for controlling the output of controlled time slot by controlling command control word features that two mapping algorithms are combined to create the mapping relation between command control word and controlled time slot and when the number of command control words is equal to that of controlled time slots, the 2nd or the 3rd mapping algorithm is used to create the mopping relation between command control word and controlled time slot, so improving the control quality.
Description
Technical field
The present invention relates to the communications field, relate in particular to the method for controlling controlled time slot output by the control command control word.
Background technology
In TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system, when a user terminal is connected by network side foundation conversation or other data with another user terminal or service content provider, all need carry out the control of Synchronization Control and power in each terminal and network side.Wherein the purpose of Synchronization Control is to guarantee that communicating pair can correctly receive the data that the other side sends, and avoids phase mutual interference to each other simultaneously.Power control then guarantees the quality of receiving terminal (base station or travelling carriage) received signal, and can improve the capacity of system to greatest extent, that is to say that transmitting power control is to make transmitting terminal keep transmitting power to be in reduced levels and can make receiving terminal obtain the effect of enough signal qualitys in order to realize as far as possible.
Because in the TD-SCDMA system, signal is by radio frame transmission, and a radio frames is divided into two subframes, each subframe comprises a plurality of time slots, such as comprising seven normal time slots and three special time slots.Each normal time slot is ascending time slot or descending time slot by system configuration as required.When terminal and network side are set up link and be connected, then need to occupy the code channel resource in corresponding ascending time slot and the descending time slot.Because link is present in one or several time slot, so the recipient generally realizes Synchronization Control and power merit system by controlling those time slots.
At present, industry generally is to produce corresponding synch command control word and it is sent to transmit leg according to receiving each time slots point by the recipient at the Synchronization Control of TD-SCDMA system, make transmit leg adjust the transmitting time of corresponding time slot, to reach the synchronous effect of Data Receiving.Power control then produces corresponding power command control word and it is sent to transmit leg according to power that receives each time slot or signal to noise ratio according to the recipient, make transmit leg adjust the transmitting power of corresponding time slot, can guarantee that received signal quality can improve the effect of power system capacity again to greatest extent so that wireless communication system reaches.Here, for sake of convenience, we feed back to transmit leg with this classes such as synch command control word and power command control words by the recipient and are referred to as command control word in order to the order unification of controlling transmit leg output information (as transmitting power, launch time).
Wherein, when transmit leg be the base station, when the recipient is user terminal (UE), the controlled time slot of command control word control is the descending time slot that the base station sends; When transmit leg is a user terminal, when the recipient was the base station, the controlled time slot of command control word control was the ascending time slot that user terminal sends.

Embodiment
Below in conjunction with accompanying drawing, specify the present invention.
See also Fig. 1, it is a kind of flow chart of controlling the method for controlled time slot output by the control command control word.
At first carry out step S110, transmit leg is set up link with the recipient and is connected, and base station controller is with the wireless resource configuration both advised of link.Described wireless resource configuration comprises the physic channel information of communicating pair etc.Such as the number of number that comprises ascending time slot in the radio frames and descending time slot, and the number of the command control word of the number of command control word, each physical channel carrying and the position of command control word; In fact, when the base station when user terminal is set up link and is connected, the base station is the recipient for up link, for down link is transmit leg, same user terminal is the recipient for down link, for up link is the recipient, and promptly base station and user terminal are controlled the output of the other side's controlled time slot by command control word separately; Transmit leg and recipient be according to fixing rule, the controlled time slot of base station controller configuration sorted determine the sequence number of each controlled time slot, base station controller configure order control word sorted determine the sequence number of each control command word;
Carry out step S120 then, set up mapping relations between command control word and the controlled time slot according to mapping algorithm;
Carry out step S130 subsequently, the recipient is according to the described controlled gap information that receives, the control information of the controlled time slot of control is write with described controlled time slot and has in the command control word of mapping relations, then described command control word is carried on physical channel and is sent to transmit leg;
Carry out step S140 at last, transmit leg obtains described command control word, and the mapping algorithm by step S120 finds the controlled time slot of described command control word mapping, with the output of the control time slot of being controlled.
In above-mentioned steps S120 and step S140, can pass through UL

But the inventor controls and finds often Be Controlled and influence the serious consequence of The whole control quality not of certain or certain a few fixing controlled time slots in the controlled time slot output procedure using first kind of mapping algorithm.And among above-mentioned steps S120 and the step S140, can also pass through another kind of mapping algorithm UL

But the inventor finds that again still there is defective in second kind of mapping algorithm between mentioned order control word and the controlled time slot to control of quality.
Such as: the quantity of controlled time slot is 3 (its sequence number is respectively S0, S1, S2), the quantity of command control word is 4 (its sequence number is respectively TPC0, TPC1, TPC2 and TPC3), see also table 1, its expression command control word is determined corresponding controlled time slot according to second kind of mapping algorithm.

| 4 | S0 | S1 | S0 | S1 |
| 7 | S1 | S2 | S1 | S2 |
| 10 | S2 | S0 | S2 | S0 |
Can find out from table 1, work as SFN '=1,4,7,10 o'clock, 4 command control words were only controlled the output of two time slots in each subframe, and and be unrealized to the control of all time slots, waste the resource of command control word thus, and also do not reached the purpose of many as far as possible control time slots, and then the quality of influence control output.
That is to say, control in the method for controlled time slot output in the control command control word, if adopt second kind of mapping algorithm, will there be incomplete mapping relations between existing command control word and the controlled time slot, thereby causing taking place on the one hand, several command control words map to the identical controlled time slot of part simultaneously, and some time slot situation of not shone upon on the other hand by command control word, cause thus and both wasted system resource, and do not reach as far as possible purposes of controlling time slots, and then the quality of influence control output more.
The inventor is known by testing further analysis: when adopting first kind of mapping algorithm to carry out the output of controlled time slot, have only under controlled time slot and the situation that the command control word number equates, the mapping relations between command control word and the controlled time slot are just all fixed on every frame.Because in the case, the recipient is carried on command control word in the process that physical channel sends, often there is some physical channel because rate-matched etc. are former thereby cause and can't send, cause this command control word that is carried on those physical channels also can't send thus, thereby cause transmit leg not control the output that has the controlled time slot of mapping relations with described command control word according to the content of described command control word.But under controlled time slot and the command control word situation that number does not equate, owing to the mapping relations between command control word and the controlled time slot are not what fix at every frame, can not occur certain or certain a few controlled time slots thus can often can controlled situation.
And, when adopting second kind of mapping algorithm to carry out the output of controlled time slot, because it is unfixing that command control word is shone upon the mapping relations of controlled time slot, thereby solved under command control word and situation that controlled time slot equates, often be not sent out the controlled time slot often not controlled consequence that causes described command control word to shine upon owing to certain or some command control words.Promptly, because the mapping relations between command control word and the Be Controlled time slot are unfixed, even if therefore this command control word often is not sent out, it also is unfixed causing not controlled time slot, has avoided the often not generation of this situation of Be Controlled of a certain time slot thus.
But, when the number of command control word and controlled time slot is inequality, when adopting second kind of mapping algorithm to carry out the output of controlled time slot, can taking place on the one hand, several command control words map to the identical controlled time slot of part simultaneously, and some time slot situation of not shone upon on the other hand by command control word, causing had thus both wasted system resource, and did not reach the purpose of many as far as possible control time slots.Export but adopt first kind of mapping algorithm to carry out controlled time slot, it is very even to find that mapping distributes, and can as far as possible control time slots more, and then reach the consequence that improves control of quality.With following two examples is example, comes comparison first mapping algorithm and second mapping algorithm.
At first, still the quantity with controlled time slot is 3 (its sequence number is respectively S0, S1, S2), the quantity of command control word is that 4 (its sequence number is respectively TPC0, TPC1, TPC2 and TPC3) are with example, the inventor finds as if the mapping relations of setting up with first kind of mapping algorithm between command control word and the controlled time slot, can guarantee that then each controlled time slot is all controlled on every frame, see also table 2.
Table 2
| The corresponding time slot of first kind of mapping algorithm command word | The corresponding time slot of second kind of mapping algorithm command word | |||||||
| SFN’ | TPC0 | TPC1 | TPC2 | TPC3 | TPC0 | TPC1 | TPC2 | FPC3 |
| 0 | S0 | S1 | S2 | S0 | S0 | S1 | S2 | S1 |
| 1 | S1 | S2 | S0 | S1 | S2 | S0 | S2 | S0 |
| 2 | S2 | S0 | S1 | S2 | S1 | S0 | S1 | S2 |
| 3 | S0 | S1 | S2 | S0 | S1 | S2 | S0 | S2 |

| 7 | S1 | S2 | S0 | S1 | S1 | S2 | S1 | S2 |
| 10 | S1 | S2 | S0 | S1 | S2 | S0 | S2 | S0 |
As known from Table 2, under the situation that command control word is had more than needed, first mapping algorithm can guarantee that each controlled time slot can be controlled on every frame, has made full use of the command control word resource.And because being evenly distributed of controlled time slot also improved the quality of control thus.
Next please refer to table 3, it is 3 (its sequence number is respectively S0, S1, S2) for the quantity of controlled time slot, and command control word was determined the mapping table of corresponding controlled time slot when the quantity of command control word was 2 (its sequence number is respectively TPC0, TPC1) according to two kinds of mapping algorithms.
Table 3
| The corresponding time slot of first kind of mapping algorithm command word | The corresponding time slot of second kind of mapping algorithm command word | |||

| 3 | S0 | S1 | S2 | S0 |
| 4 | S2 | S0 | S1 | S0 |
| 5 | S1 | S2 | S1 | S2 |
From the above, the mapping of first kind of determined corresponding time slot of mapping algorithm distributes very even.Suppose that TPC1 often is not sent out, then control of quality depends mainly on TPC0, can find out from table 4, first kind of mapping algorithm can make that each time slot can be controlled uniformly, and according to second kind of mapping algorithm, thereby will cause the long-time not controlled consequence that causes controlled quality to descend of certain time slot.
For this reason, the inventor has proposed a kind ofly to control the method for controlled time slot output by the control command control word, controls transmit leg output to realize the recipient, comprising:
S210: transmit leg is set up link with the recipient and is connected, base station controller is with the wireless resource configuration both advised of link simultaneously, described wireless resource configuration comprises both sides' physic channel information etc., described physic channel information comprises the information of the controlled time slot of both sides and the information of command control word, comprise the number of controlled time slot, the timeslot number of each controlled time slot in the information of described controlled time slot, comprise the number of the command control word that the total number of command control word, each physical channel carry and the position of command control word in the information of described command control word; Transmit leg and recipient be according to fixing rule, the controlled time slot of base station controller configuration sorted determine the sequence number of each controlled time slot, base station controller configure order control word sorted determine the sequence number of each control command word;
S220: the recipient judges whether described controlled number of time slots equates with the number of command control word, if, then according to UL

S240: transmit leg obtains all command control words, finds the controlled time slot of each command control word mapping by the mapping relations shown in the step 220, with the output of control corresponding time slot.
And the inventor improves second kind of mapping algorithm,

ULslotBe the quantity of controlled time slot.For this reason, the present invention's method flow diagram of controlling the output of controlled time slot by the control command control word is revised as shown in Figure 3.
In above-mentioned control method, the inventor has adopted two kinds of mapping algorithms mode of (first kind of mapping algorithm and second kind of mapping algorithm combine or first kind of mapping algorithm and the third mapping algorithm) of combining to set up mapping relations between command control word and the controlled time slot.When command control word equates with the quantity of controlled time slot, adopt second kind of mapping algorithm or the third mapping algorithm to set up mapping relations between command control word and the controlled time slot, often be not sent out thereby solved in the prior art, and then cause the often not controlled problem of certain controlled time slot owing to adopting first kind of mapping algorithm to cause when certain or some command control words between command control word and the controlled time slot.Under the unequal situation of the quantity of command control word and controlled time slot, the present invention adopts first kind of mapping algorithm to set up mapping relations between command control word and the controlled time slot, thereby avoid adopting second kind of mapping algorithm that several command control words take place and map to the identical controlled time slot of part simultaneously, and the situation that the part time slot is not shone upon by command word, and then cause certain or certain often not controlled situation of the controlled time slot in this place equally, improve the The whole control quality of control output thus.
When the recipient is the base station, then described transmit leg is a user terminal, and described controlled time slot is the ascending time slot that user terminal sends.The recipient is a user terminal simultaneously, and then described transmit leg is the base station, and described controlled time slot is the descending time slot that the base station sends.
