Description

A kind of time division duplexing system physical accidental access channel parameter configuration and indicating means

Technical field

The present invention relates to moving communicating field, particularly relate to accidental access channel parameter configuration of TDD (Time Division Duplex, time division duplex) system and indicating means.

Background technology

The frame structure of LTE (Long Term Evolution, Long Term Evolution) system TDD (Time Division Duplex, time division duplex) pattern as shown in Figure 1.In this frame structure; a 10ms (307200Ts; radio frames 1ms=30720Ts) is divided into two fields; the long 5ms of each field (153600Ts); comprise the common time slot that 8 length are 0.5ms; and three special time slots; be DwPTS (DownlinkPilot Time Slot; descending pilot frequency time slot), GP (Guard Period; protection is at interval) and UpPTS (Uplink Pilot Time Slot; uplink pilot time slot), and these three special time slot length sums be 1ms (30720Ts).Subframe 1 is made up of three special time slots all the time; When 2 downstream-to-upstream transfer points were arranged in the 10ms, subframe 6 was made up of three special time slots, and under other situation, 6 of subframes comprise DwPTS (at this moment DwPTS length is 1ms); Other subframe is made up of 2 common time slots.

In above-mentioned frame structure, subframe 0,5 and DwPTS are used for downlink transfer all the time, and subframe 2 and UpPTS are used for uplink all the time.When 2 downstream-to-upstream transfer points were arranged in the 10ms, subframe 7 also was used for uplink.

Under the tdd mode of LTE system, Physical Random Access Channel (PRACH, PhysicalRandom Access Channel) has two big classes:

The first kind is transmitted in general sub-frame of uplink (subframe that does not comprise special time slot), and the form of this class PRACH has 4 kinds, is respectively

● Preamble format 0 (leading form 0): account for 1 sub-frame of uplink, CP (Cyclic Prefix, Cyclic Prefix) length is 3168TS, and preamble (leading) length is 24576Ts;

● Preamble format 1 (leading form 1): account for 2 sub-frame of uplink, CP (Cyclic Prefix) length is 21024TS, and preamble (leading) length is 24576Ts;

● Preamble format 2 (leading form 2): account for 2 sub-frame of uplink, CP (Cyclic Prefix) length is 6240TS, and preamble (leading) length is 2 * 24576Ts;

● Preamble format 3 (leading form 3): account for 3 sub-frame of uplink, CP (Cyclic Prefix) length is 21024Ts, and preamble (leading) length is 2 * 24576Ts;

Second class is transmitted in UpPTS, and the form of this class PRACH has a kind, for

● Preamble format 4 (leading format 4): CP (Cyclic Prefix) length is 448Ts, and preamble (leading) length is 4096Ts;

At frequency domain, above-mentioned various PRACH account for 6 RB (Resource Block, Resource Block), and each RB comprises 12 subcarriers, and the bandwidth of each subcarrier is 15kHz.

Mobile phone at first will carry out down-going synchronous when connecting system, mobile phone demodulation broadcast channel obtains the configuration parameter of PRACH then, finishes uplink synchronous by PRACH more at last, and foundation is connected with the base station.Here, the configuration parameter of PRACH comprises density (having what PRACH channels to use), leading form (preamble format is hereinafter to be referred as form), version number under the tdd mode in the unit interval.Wherein, form, density is identical but the version difference means that preamble format is identical, the quantity of PRACH is identical in the unit interval, but the time domain of these PRACH or frequency domain position difference.For with a kind of form, the PRACH of same density is provided with a plurality of versions, it is that the PRACH by the different districts of same BTS management is broken up in time that different districts uses the purpose of different editions, each sub-district that same base station is managed proposes the processing request of PRACH channel in the different moment, it is constantly too busy at some to avoid occurring the base station, and in other phenomenons of handling of free of data constantly.In addition, be the PRACH of preamble format 4 for type, owing to do not send data in the UpPTS, so different districts uses different versions, the PRACH of each sub-district has different time domains or frequency domain position, reduces the effect that minizone PRACH disturbs in addition.

But as how less interface-free resources the PRACH configuration parameter being indicated to terminal, is problem demanding prompt solution.

Step 2, the version number R that needs for the density calculation of every kind of preamble format and support thereof is so that the PRACH of all sub-districts of same BTS management evenly distributes in time; Computational methods can adopt one of following three kinds of methods:

Method A1, determine for each PRACH form with and the density supported, in different descending, the sub-frame of uplink proportional arrangement, make evenly distribute the in time maximum of needed minimum version number of the PRACH of all sub-districts of same BTS management;

Specifically, calculate that every kind of PRACH form and density are descending for each, the minimum value of uplink ratio, determine that according to the result maximum in the minimum value descending at all, that uplink ratio is corresponding is as the version number of needs.Therefore the version number that needs is that the version number of every kind of PRACH form and density correspondence all is the maximum of needed minimum version number in various descending, the uplink ratio.

Wireless frame structure as shown in Figure 1, ratio descending, sub-frame of uplink has the plurality of optional item: 3: 1,2: 2,1: 3,5: 3,3: 5,1: 8,2: 7,3: 6.

Illustrate: when three sub-districts of BTS management, for preamble format 1, at density D=2PRACH/10ms, descending sub frame: under the situation of sub-frame of uplink=1: 3, the version number that needs is maximum, as long as therefore determine at needed minimum version number in such cases.At this moment R=1 or 2 or 3 is identical in the effect of breaing up of time domain, and as shown in Figure 3, Cell 0, Cell 1, Cell 2 are three sub-districts under the same base station, as can be seen, no matter R=1 or R=2 or R=3, the base station all needs to handle 3 PRACH at synchronization.Therefore, get minimum version number R=1 this moment.Can determine thus,,, determine the version number R=1 that needs for the PRACH of 3 sub-districts that make same BTS management evenly distributes in time for the situation of preamble format 1, density D=2PRACH/10ms.

According to method A1, in the LTE system, when three sub-districts of each BTS management, determine that the version number R that needs under the density of every kind of preamble format and support thereof is as follows:

For preamble format 0, for all density, R=3;

For preamble format 1 or 2, for density D=0.5PRACH/10ms, R=3; For D=1,3,5PRACH/10ms, R=2; For density D=2PRACH/10ms, R=1;

For preamble format 3, for D=0.5PRACH/10ms, R=3; For D=1,3,5PRACH/10ms, R=2; For density D=2PRACH/10ms, R=1;

For preamble format 4, for D=0.5PRACH/10ms, R=3; For D=1,3,5PRACH/10ms, R=2; For density D=2,10PRACH/10ms, R=1;

According to method A1, in the LTE system, when four sub-districts of each BTS management, determine that the version number R that needs under the density of every kind of preamble format and support thereof is as follows:

For preamble format 0, for D=0.5 R=4, for other density, R=3;

For preamble format 1 or 2, for density D=0.5PRACH/10ms, R=4; For D=1,3,5PRACH/10ms, R=2; For density D=2PRACH/10ms, R=1;

For preamble format 3, for D=0.5PRACH/10ms, R=4; For D=1,3,5PRACH/10ms, R=2; For density D=2PRACH/10ms, R=1;

For preamble format 4, for D=0.5PRACH/10ms, R=4; For D=1,3,5PRACH/10ms, R=2; For density D=2,10PRACH/10ms, R=1;

Method A2, for the PRACH of all sub-districts of making same BTS management evenly distributes in time, version number R can determine according to following formula:

Formula (1)

Wherein, N _RA ^BWBe the PRACH quantity that system supports at frequency domain, N _SPBe the quantity of 10ms internal conversion point, D is the density of PRACH.

For example, if $N_{\mathrm{RA}}^{\mathrm{BW}}=6,$ N _SP=2, D=1, then

In the method, R changes according to the variation of system configuration, such as according to N _RA ^BW, N _SPAnd change, the benefit of She Zhiing is like this, and the PRACH quantity that system supports at frequency domain is many more, and the version number that is provided is many more, and the chance that the PRACH between different districts sends on identical time-frequency domain is few more, can reduce interference thus.

When adopting this kind method to determine version quantity, can often, then need base station and terminal calculated version number voluntarily by getable version number if it all can not be placed in the configuration set.

Method A3, when BTS management n sub-district, the version number R=n (1＜=n＜=4) of every kind of preamble format and density combinations adopts this kind method to determine that version number also is that PRACH for all sub-districts of making same BTS management can evenly distribute in time.

For example, 3 sub-districts of BTS management, then the version number R of every kind of preamble format and density combinations is 3.

Step 3, the density that each PRACH form and each PRACH form are supported or also have version number information to be kept in the PRACH configuration set;

With the PRACH form with and the density combinations supported after be kept in the PRACH configuration set.

According to version number optionally for the PRACH form with and the version number of the density distribution respective numbers supported; For the PRACH form and the density that are assigned version number, the combination corresponding relation of record PRACH form and density and version number in the PRACH configuration set.

Distribution method adopts one of following method:

Method B1 distributes the r of version number of respective numbers according to version number, and respective record is in the PRACH set.For example: r can be 0,1 ..., R-1;

If the version number R of certain preamble format and density combinations obtains by method A1 or A3 in the step 220, then preferably adopt method B1 to obtain version number.The benefit that employing marks the mode of version number is to make the base station when the channel version of configurating terminal and/or density higher flexibility to be arranged, dispose more convenient, fast.

Method B2 does not specify version number in the PRACH configuration set, but calculates by terminal when configuration; Such as, can adopt following formula to calculate:

$r=N_{\mathrm{ID}}^{\mathrm{cell}}\mathrm{mod}R$ Formula (2)

Wherein, N _{Cell ID}Expression sub-district ID value is that the signaling terminal is passed through in the base station.

When version number more for a long time, preferably adopt this kind mode to obtain version number.For example, if when the method A2 of the version number R of certain preamble format and density combinations by previous step obtains, therefore can adopt this kind method because version number is big.Terminal calculates version number R by system parameters and the above-mentioned formula (1) that obtains, and obtains version number according to this formula (2) again.

When the version number of all PRACH forms is calculated by terminal, only preserve the density that each PRACH form and each PRACH form are supported in the PRACH table.

Following examples are illustrated the configuration set that various PRACH forms may generate under different densities and version number's situation respectively, and the final configuration set that generates can be the combination of following various situations.
