Description

Method and device for configuring special time slots in long term evolution system

technical field

The invention relates to the field of communication technology, in particular to a configuration method and device for a special time slot in a long-term evolution system.

Background technique

The frame structure of the LTE (Long Term Evolution, Long Term Evolution) system is shown in Figure 1. In this frame structure, a 10ms radio frame (radio frame) is divided into two 5ms half frames (half frame), each A half-frame is composed of 5 subframes (Sub frame) with a length of 1ms, including 4 ordinary subframes and 1 special subframe. The ordinary subframe contains two 0.5ms time slots, and the special subframe consists of 3 The three special time slots are: DwPTS (Downlink Pilot Time Slot, downlink pilot time slot), UpPTS (Uplink Pilot Time Slot, uplink pilot time slot), GP (GuardPeriod, guard interval), in:

UpPTS: Mainly used to carry uplink channels, usually transmitting Physical Random Access Channel (PRACH);

GP: Mainly used as a guard interval for uplink and downlink conversions;

DwPTS: In addition to transmitting fixed synchronization channels (PSCH) and control channels (PHICH, PDCCH, PCFICH), traffic channels (PDSCH) can also be transmitted. The capacity of traffic channels is determined by the number of symbols configured by DwPTS.

Based on the above-mentioned frame structure of LTE, there are two uplink and downlink conversion points in the LTE system. The uplink and downlink conversion points are determined by the service subframe ratio relationship and the special time slot ratio relationship. The ratio of the number of symbols occupied by the three special time slots (DwPTS, GP and UpPTS) respectively.

LTE system, as the next-generation mobile communication technology of TD-SCDMA (Time Division Synchronized Code Division Multiple Access, time division synchronous code division multiple access system) smooth evolution, will coexist with TD-SCDMA for a long time, except for LTE In addition to the dedicated D frequency band (2570~2620MHz), it will also be used with TD-SCDMA adjacent frequency in the TD-SCDMA F frequency band (1880~1920MHz) and E frequency band (2320~2370MHz).

The inventor found in the process of implementing the present invention that when the LTE system and the TD-SCDMA system coexist and are in adjacent frequency bands, the problem of adjacent frequency interference will occur, that is, when the DwPTS of LTE overlaps with the UpPTS of TD-SCDMA , the signal sent by the LTE base station will interfere with the received signal of the TD-SCDMA base station; when the UpPTS of LTE overlaps with the DwPTS of TD-SCDMA, the signal sent by the TD-SCDMA base station will interfere with the received signal of the LTE base station. In addition, if the DwPTS (or UpPTS) of LTE is extended to the GP of TD-SCDMA, it will also cause the uplink and downlink signal interference between the LTE system and TD-SCDMA.

To sum up, in the phase of adjacent frequency coexistence between LTE system and TD-SCDMA system, if the time lengths of the three special time slots (DwPTS, GP and UpPTS) are improperly configured, it will lead to the interference between LTE system and TD-SCDMA system. There is interference between the uplink and downlink signals, so that the adjacent frequency coexistence of the LTE system and the TD-SCDMA system cannot be effectively realized.

Detailed ways

In order to provide a solution to effectively realize the coexistence of adjacent frequencies in the LTE system and the TD-SCDMA system, the embodiment of the present invention provides a method and device for configuring special time slots in the long-term evolution system. The embodiments are described, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

According to the embodiment of the present invention, in order to avoid the adjacent frequency interference between the LTE system and the TD-SCDMA system, an optimization scheme is proposed for the ratio relationship between the special time slots (DwPTS, GP and UpPTS) in the LTE system. The ratio relationship among them is reflected by the number of symbols occupied by each special time slot. Specifically, in order to avoid adjacent frequency interference between the LTE system and the TD-SCDMA system while ensuring the alignment of the service time slots, when configuring the number of symbols occupied by DwPTS, GP and UpPTS, the configuration principles are as follows :

1. The DwPTS of LTE cannot overlap with the UpPTS of TD-SCDMA, and cannot extend beyond the DwPTS of TD-SCDMA to the GP of TD-SCDMA system;

2. The UpPTS of LTE cannot overlap with the DwPTS of TD-SCDMA, and cannot extend beyond the UpPTS of TD-SCDMA to the GP of the TD-SCDMA system.

According to the above configuration principles, it is ensured that the DwPTS and UpPTS of LTE are respectively outside the GP of the TD-SCDMA system. As shown in Figure 2, the left boundary of the GP of the TD-SCDMA system is A, and the right boundary is B. When configuring the DwPTS of the LTE system, the right border of the DwPTS should be before the left border A of the GP in the TD-SCDMA system. When configuring the UpPTS of the LTE system, the left border of the UpPTS should be in the TD-SCDMA system After the right boundary B of the GP. It should be understood that FIG. 2 is only a schematic diagram showing the relationship between the special time slots in the LTE system and the special time slots in the TD-SCDMA system, and does not represent the actual time slot ratio relationship.

Embodiment one

Embodiment 1 of the present invention provides a method for configuring special time slots in an LTE system. The method is based on the proportional relationship between uplink and downlink service time slots configured in the TD-SCDMA system and the proportional relationship between uplink and downlink service subframes configured in the LTE system. , to determine the configuration mode of the special time slot in the LTE system.

As shown in FIG. 3 , the method for configuring a special time slot in an LTE system provided by Embodiment 1 of the present invention mainly includes the following steps:

Step 301 , according to the number of uplink service time slots in the TD-SCDMA system, determine the first total time occupied by uplink service time slots, GPs in special time slots and UpPTS in the TD-SCDMA system.

Step 302: Determine the second total time occupied by the uplink service subframes in the LTE system according to the number of uplink service subframes in the LTE system.

There is no strict execution sequence for the above steps 301 and 302. In practical applications, as mentioned above, step 301 can be executed first, and then step 302 can be executed, or step 302 can be executed first, and then step 301 can be executed, or the two steps can be executed at the same time .

Step 303, according to the first total time determined in step 301, the second total time determined in step 302, and the time occupied by each symbol in the special time slot of the LTE system, determine the maximum number of symbols of the DwPTS in the special time slot of the LTE system.

Step 304: According to the determined maximum number of symbols of the DwPTS, configure the number of symbols respectively occupied by DwPTS, GP and UpPTS in the special time slot in the LTE system. So far, the configuration process of the special time slot in the LTE system ends.

In the above technical solution provided by Embodiment 1 of the present invention, the time determined in step 301 is the time required for the uplink service in the TD-SCDMA system without interference, and the time determined in step 302 is the time required for the uplink service in the LTE system The required time, by subtracting the second total time from the first total time, can determine the minimum value of the time occupied by GP and UpPTS in the LTE system under the condition that the uplink service in the TD-SCDMA system is not interfered, That is, the time occupied by the GP plus the time occupied by the UpPTS needs to be greater than or equal to the time difference between the first total time minus the second total time, and then determine the maximum number of symbols occupied by the DwPTS according to the time difference.

In step 301 of the process shown in Figure 3, according to the number of uplink service time slots in the TD-SCDMA system, the process of determining the first total time occupied by the uplink service time slots in the TD-SCDMA system, the GP in the special time slot, and the UpPTS , as shown in Figure 4, mainly includes the following steps:

Step 401. Determine the proportional relationship between uplink and downlink service time slots configured in the TD-SCDMA system.

At present, in the TD-SCDMA system, the proportional relationship between uplink and downlink service time slots mainly includes five types: 1:5, 2:4, 3:3, 4:2, 5:1, etc. In step 401, according to The actual configuration of the current system determines the proportional relationship M:N of the uplink and downlink service time slots configured in the TD-SCDMA system.

Step 402, determine the number of uplink service time slots in the TD-SCDMA system.

In this step 402, the number of uplink service time slots in the TD-SCDMA system is the M value in the ratio relationship M:N of uplink and downlink service time slots configured in the system.

Step 403, utilize the quantity of the uplink service time slot in the TD-SCDMA system to multiply the time that each time slot occupies, add the time that the GP in the special time slot of the TD-SCDMA system occupies and the time that UpPTS occupies, obtain the first The total time, so far, the process of determining the first time ends.

In this step 403, the first total time can be determined by the following formula:

T1＝M*625+125+75;

Among them, M is the number of time slots occupied by uplink services in the TD-SCDMA system, 625 is the time occupied by each time slot in the TD-SCDMA system; 125 is the time occupied by UpPTS; 75 is the time occupied by GP. The unit of value is us.

According to this formula, if the ratio of the uplink and downlink service time slots configured in the TD-SCDMA system is 2:4 or 2:5, 2:4 means that the downlink time slot TS0 is not included, and 2:5 means that the downlink time slot is included In the case of time slot TS0, according to the ratio of the uplink and downlink service time slots, it can be determined that the number of time slots occupied by the uplink service is 2, thereby determining the TD-SCDMA system configured as 2:4 (or 2:5) The total time occupied by the uplink service is 2*625+125+75=1550us.

In step 302 of the process shown in Figure 3, the process of determining the number of uplink service subframes in the LTE system is basically the same as the process described in the above steps 401 to 402, that is, first determine the number of uplink and downlink service subframes configured in the LTE system If the ratio is S:N, the number of uplink service subframes in the LTE system can be determined to be S according to the ratio. After determining the number of uplink service subframes in the LTE system, the second total time can be determined by the following formula:

T2=S*1000;

Where: S is the number of uplink service subframes in the LTE system, 1000 is the time occupied by each subframe in the LTE system, and the unit of each value in the formula is us.

In step 303 of the process shown in Figure 3, according to the first total time determined in step 301, the second total time determined in step 302, and the time occupied by each symbol in the special time slot of the LTE system, the special time slot of the LTE system is determined The maximum number of symbols in the DwPTS can be preferably obtained through the following two specific implementation methods:

Specific implementation mode one

In the first embodiment, the minimum number of symbols occupied by the GP and the UpPTS in the special time slot of the LTE system is determined first, and then the maximum number of symbols of the DwPTS is determined.

As shown in Figure 5, determining the maximum number of symbols of the DwPTS in the special time slot of the LTE system includes the following steps:

Step 501, using the first total time determined in step 301 to subtract the second total time determined in step 302 to obtain a time difference.

Step 502: divide the time difference calculated in step 501 by the time occupied by each symbol in the special time slot of the LTE system to obtain the minimum number of symbols occupied by GP and UpPTS in the special time slot of the LTE system.

Step 503 , judging whether the minimum number of symbols calculated in step 502 is a positive number, if yes, execute step 504 , if not, execute step 505 .

Step 504, subtracting the minimum number of symbols from the total number of symbols included in the special time slot of the LTE system to obtain the maximum number of symbols of the DwPTS in the special time slot. So far, the process of determining the maximum number of symbols of the DwPTS ends.

Step 505, round up the minimum number of symbols, and use the total number of symbols included in the special time slot of the LTE system to subtract the minimum number of symbols after rounding up, to obtain the maximum number of symbols of the DwPTS in the special time slot, so far, determine The procedure for the maximum number of symbols of DwPTS ends.

In step 502 of the process shown in Figure 5, according to the difference of the CP (Cyclic Prefix, cyclic prefix) type configured in the LTE system, the time occupied by each symbol in the special time slot of the LTE system is also different, specifically:

When the CP type configured in the LTE system is a regular CP (that is, a short CP), the time occupied by each symbol in a special time slot is:

66.7us+4.7us≈71.4us.

Here, the time occupied by each symbol in the special time slot is 71.4 is an approximate value. In the actual system, the first symbol and the eighth symbol of the special time slot in some LTE systems occupy about 5.2us. According to this, the special The time taken by each symbol in the slot is:

[(66.7us+4.7us)×12+(66.7+5.2)×2]÷14≈71.4us.

Wherein: 66.7us and 4.7us are approximate values, and the following situations are similar to this, and the non-integer numbers in the embodiments of the present invention all retain one decimal place.

When the CP type configured in the LTE system is an extended CP (that is, a long CP), the time occupied by each symbol in a special time slot is:

66.7us+16.7us=83.4us.

Wherein: 66.7us and 16.7us are approximate values, and the following situations are similar to this, and the non-integer numbers in the embodiments of the present invention all retain one decimal place.

In step 504 and step 505 of the process shown in Figure 5, according to the different CP types configured in the LTE system, the total number of symbols included in the special time slot of the LTE system is also different, specifically:

When the CP type configured in the LTE system is a regular CP (ie, short CP), the total number of symbols included in the special time slot of the LTE system is: 14.

When the CP type configured in the LTE system is an extended CP (ie, long CP), the total number of symbols included in the special time slot of the LTE system: 12.

Specific implementation mode two

In the second embodiment, the maximum number of symbols of the DwPTS can be determined directly.

As shown in Figure 6, determining the maximum number of symbols of the DwPTS in the special time slot of the LTE system includes the following steps:

Step 601, subtracting the second total time determined in step 302 from the first total time determined in step 301 to obtain a first time difference.

Step 602, using the second time difference obtained by subtracting the first time difference from the total time occupied by the special time slot of the LTE system.

Step 603: Divide the second time difference by the time occupied by each symbol in the special time slot of the LTE system to obtain the maximum number of symbols occupied by the DwPTS in the special time slot of the LTE system.

Step 604, judging whether the maximum number of symbols calculated in step 603 is a positive number, if not, execute step 605; if yes, then the process of determining the maximum number of symbols of the DwPTS ends.

Step 605: Decrease the value of the maximum number of symbols. So far, the process of determining the maximum number of symbols of the DwPTS ends.

In step 304 of the process shown in Figure 3, according to the maximum number of symbols of the DwPTS determined, the number of symbols occupied by DwPTS, GP and UpPTS in the special time slot in the LTE system is configured, as shown in Figure 7, mainly including the following steps:

Step 701, according to the CP type configured in the LTE system, determine the total number of symbols included in the special time slot of the LTE system.

Step 702, configure the number of symbols occupied by the DwPTS in the special time slot to be less than or equal to the determined maximum number of symbols of the DwPTS.

Step 703, configure the number of symbols occupied by GP in the special time slot to be greater than or equal to the minimum number of symbols occupied by GP, the minimum number of symbols is an integer obtained by dividing the time occupied by GP by the time occupied by each symbol in the special time slot and rounding up .

In step 703, if it is a conventional CP, the time occupied by GP is 75us, and the time occupied by each symbol in a special time slot is 1000us/14≈1.05, and the integer obtained by rounding up is 2; if it is an extended CP, GP occupies The time taken by each symbol in the special time slot is 75us, and the time occupied by each symbol in the special time slot is 1000us/12=0.9, and the integer obtained by rounding up is 1.

Step 704, configure the number of symbols occupied by UpPTS in the special time slot to be the total number of symbols included in the determined special time slot of the LTE system, subtract the number of symbols occupied by DwPTS and the number of symbols occupied by GP, so far, configure the special number of symbols in the LTE system The flow of the time slot ends.

In order to better understand the technical solution provided by Embodiment 1 of the present invention, the preferred embodiment of the present invention will be described in detail below in combination with specific application scenarios:

The scenario provided by this embodiment is: the proportion relationship between uplink and downlink service time slots configured in the TD-SCDMA system is 2:4 or 2:5, and the proportion relationship between uplink and downlink service subframes configured in the LTE system is 1:3.

According to this application scenario, the chips and schedule of each time slot in the TD-SCDMA system are as follows:

The number of uplink service time slots in the TD-SCDMA system can be determined according to the proportional relationship between the uplink and downlink service time slots configured in the TD-SCDMA system, and then the uplink service time slots, GPs in special time slots, and the first occupied by UpPTS can be determined according to the above table. A total time:

T1＝2*625+125+75＝1550us;

The second total time T2=1*1000=1000us occupied by the uplink service subframe in the LTE system can be determined according to the proportional relationship between the uplink and downlink subframes in the LTE system;

If the above specific implementation mode 1 is adopted, the process of determining the maximum number of symbols is as follows:

When determining the maximum number of symbols of the DwPTS in the special time slot of the LTE system, the first total time 1550us is used to subtract the second total time 1000us to obtain a time difference of 550us;

If the CP type configured in the LTE system is a regular CP, divide the time difference 550us by the time occupied by each symbol in the special time slot of the LTE system 71.4us (that is, 66.7us+4.7us) to obtain the special time slot of the LTE system The minimum number of symbols occupied by GP and UpPTS in the time slot is 7.7, and the value after rounding up is 8, and the total number of symbols included in the special time slot of the LTE system is 14 minus the minimum number of symbols after rounding up is 8, Obtain the maximum symbol number 6 of DwPTS in this special time slot;

If the CP type configured in the LTE system is an extended CP, divide the time difference 550us by the time occupied by each symbol in the special time slot of the LTE system 83.4us (ie 66.7us+16.7us) to obtain the special time slot of the LTE system The minimum number of symbols occupied by GP and UpPTS in the time slot is 6.6, which is rounded up to 7, and the total number of symbols included in the special time slot of the LTE system is 12 minus the minimum number of symbols 7 after rounding up to obtain the special Maximum number of symbols for DwPTS in a slot 5.

If the above-mentioned specific implementation mode 2 is adopted, the process of determining the maximum number of symbols is as follows:

Use the first total time 1550us to subtract the second total time 1000us to obtain the first time difference 550us, and use the total time 1000us occupied by the special time slot of the LTE system to subtract the first time difference 550us to obtain the second time The difference is 450us;

If the CP type configured in the LTE system is a regular CP, divide the second time difference 450us by the time occupied by each symbol in the special time slot of the LTE system 71.4us to obtain the maximum DwPTS occupied by the special time slot of the LTE system The number of symbols is 6.3, and the maximum number of symbols 6.3 is rounded down to get 6;

If the CP type configured in the LTE system is an extended CP, divide the second time difference 450us by the time occupied by each symbol in the special time slot of the LTE system 83.4us to obtain the maximum symbol occupied by DwPTS in the special time slot of the LTE system 5.3, and round down the largest symbol number 5.3 to get 5.

To sum up, under the normal CP configuration, the maximum number of symbols of the determined DwPTS is 6, that is, when the system configures the number of symbols of the DwPTS, the maximum number of symbols is 6; under the extended CP configuration, the maximum number of symbols of the determined DwPTS The number is 5, that is, when the system configures the number of DwPTS symbols, a maximum of 5 is configured. Further, if the CP type configured in the LTE system is a conventional CP, the number of symbols occupied by the GP in the configuration special time slot is greater than or equal to 2 (the determination process is as described in the above step 703), and the number of symbols occupied by the UpPTS in the configuration special time slot is The total number of symbols included in the determined special time slot of the LTE system is 14, minus the number of symbols occupied by DwPTS and the number of symbols occupied by GP; if the CP type configured in the LTE system is extended CP, configure the special time slot occupied by GP The number of symbols is greater than or equal to 1 (the determination process is as described in step 703 above), and the number of symbols occupied by UpPTS in the special time slot is configured as the total number of symbols included in the special time slot of the determined LTE system 12, minus the symbols occupied by DwPTS number and the number of symbols occupied by the GP.

According to the above configuration relationship, when the LTE system is configured as a regular CP, the special time slot DwPTS in the LTE system can occupy up to 6 symbols under the condition that the adjacent frequencies of the LTE system and the TD-SCDMA system coexist without interfering with each other. DwPTS occupies 6 symbols, and 3 symbols are added to transmit traffic channels. The downlink occupies a total of 33 symbols. After adding 3 symbols by modifying the existing standard, the system capacity gain is 3/33=9.1% (based on the existing three symbols The case of not transmitting the traffic channel is taken as an example).

When the LTE system is configured as an extended CP, under the condition that the LTE system and the TD-SCDMA system coexist in adjacent frequencies and ensure mutual non-interference, the special time slot DwPTS in the LTE system can occupy up to 5 symbols. If the DwPTS occupies 5 symbols , the traffic channel can be transmitted by adding 2 symbols, and the downlink occupies a total of 27 symbols. After adding 2 symbols by modifying the existing standard, the system capacity gain is 2/27=7.4% (based on the existing three symbols that do not transmit the traffic channel case as an example).

Therefore, according to the above configuration, the system capacity gain can be between 7.4% and 9.1%.

Embodiment 1 of the present invention further provides a configuration scheme for improving system capacity on the basis of effectively realizing the coexistence of adjacent frequencies of the LTE system and the TD-SCDMA system and making minor modifications to existing standards, as follows:

According to the above determination process, for the above application scenarios, the ratio of uplink and downlink service time slots configured in the TD-SCDMA system is 2:4 or 2:5, and the ratio of uplink and downlink service subframes configured in the LTE system is 1:3 In the case, you can configure as follows:

If the CP type configured in the LTE system is a regular CP, the three special time slots are configured as follows:

DwPTS:GP:UpPTS is: 6:6:2;

Wherein, the above ratio represents the ratio of the number of symbols occupied by the three special time slots.

If the CP type configured in the LTE system is an extended CP, the three special time slots are configured as follows:
