Description

Method for configuring uplink and downlink subframe ratio of TDD, base station and system

The present invention relates to the field of communications technologies, and in particular, to a method, a base station, and a system for configuring a TDD uplink-downlink subframe ratio. Background technique

In recent years, the new generation of wireless communication technology has developed rapidly. Compared with the third generation of wireless communication technology, the new generation of mobile communication technology has many advantages such as network architecture, small signal delay, high communication quality and fast speed. According to the classification of uplink and downlink service multiplexing, the new generation mobile communication technology can be divided into TDD (Time Division Duplex) system and FDD (Frequency Division Duplex) system.

In the TDD system, the next-generation wireless communication system defines seven different radio frame structures. As shown in Figure 1, the special subframes 102 included in the LTE (A) radio frames corresponding to the different TDD uplink-downlink subframe ratios. The number of the uplink subframe 104 and the downlink subframe 106 is different, and the configuration number corresponding to the ratio of each seed frame and the ratio of the corresponding downlink subframe (DL) to the uplink subframe (UL) are indicated in the figure. Compared with the FDD system, the TDD system has higher efficiency in utilizing system resources. The base station can use different radio frame structures of different uplink and downlink subframe ratios between base stations according to different uplink and downlink traffic.

However, due to the existence of cross-interference, the existing TDD technology limits the flexible deployment of the downlink subframe ratio configuration on the TDD system. As shown in FIG. 2, if the base station 1 serves the terminal 1, and the base station 2 serves the terminal 2, when the base station 1 currently uses the downlink subframe 202 and the base station 2 currently uses the uplink subframe 204, except for the base station 1 and the terminal 1, the base station 2, the normal signal 2 between the terminal 1, and the interference signal 1 caused by different uplink and downlink configurations between the terminal 1 and the terminal 2, and between the base station 1 and the base station 1, that is, cross interference.

In order to solve this problem, the International Organization for Standardization 3GPP launched the elMTA project in May 2010. Further enhancements to LTE Time Division Duplex (TDD) for Downlink-Uplink Interference Management and Traffic Adaptation ), how to implement service adaptation and interference management of TDD systems under hybrid networking conditions.

Specifically, in the related research of 3GPP, some reconfiguration algorithms for TDD uplink and downlink subframe proportion configuration reconfiguration are proposed. In the existing reconfiguration algorithm, the system determines the proportion of the TDD uplink and downlink subframes to be used in the next reconfiguration period according to the current traffic load, that is, the calculation is within the dynamic adjustment range (such as within a cell), and all UEs The ratio of the total amount of uplink data to be sent to the total amount of pending data to be sent by the base station, and according to the ratio of the to-be-sent data, find the closest configuration among the seven TDD uplink and downlink subframe ratios specified by the 3GPP protocol. This configuration is used as the ratio of the TDD uplink and downlink subframes to be used in the next matching period.

However, since only the dynamic adjustment range is considered in the existing reconfiguration algorithm (such as in a cell)

The ratio of the total uplink and downlink data to be sent by the UE (User Equipment). Therefore, in some scenarios, the TDD matching configuration selected by the algorithm does not meet the performance requirements of some "user groups." For example, if the service performance indicator provided to the user needs to be divided into several levels, the existing reconfiguration algorithm cannot provide the difference of the service, so that the matching configuration obtained by the calculation may not meet the performance requirements of the high-end user. .

Therefore, a new technical solution is needed, which can provide differentiated services for different types of communication devices during the configuration of the TDD uplink-downlink subframe ratio according to the priority of the communication device. Summary of the invention

In the above formula:

Pi represents the "priority value" corresponding to "user subgroup i";

Ai, Bi, etc. indicate "user group characteristic information" corresponding to "user subgroup i", such as:

1) The proportion of the number of users in the "user subgroup i" in the total number of users;

2) The number of active users in the "user subgroup i" (active users refer to users who are or are about to transmit services) the proportion of the total number of active users;

3) The number of users or active users in the "user subgroup i";

4) The service level corresponding to "user subgroup i".

At the same time, there are many different implementations of the function/, for example, if Ai represents the ratio of the total number of users (or the total number of active users) of the "user subgroup i" number of users (or the number of active users); Bi means "user The service level of subgroup i", corresponding to the function of Ai and Bi / can be table /(4,Α) = Λ χ4 χ or / (4,A) = 4 x + N , where M and N are preset constants. The matching configuration corresponding to each user subgroup can be separately calculated. For example, for the "user subgroup i", the corresponding matching configuration ii can pass:

Calculating the ratio of the total amount of uplink data to be sent and the total amount of pending data to be sent by the base station in the "user subgroup i" in the dynamic adjustment range (for example, in a cell), and according to the above-mentioned pending The data ratio, in the seven TDD uplink-downlink subframe ratios specified in the 3GPP protocol (as shown in Figure 1), finds the closest configuration, which is the matching configuration.

Step 608: Calculate the matching configuration ii, and calculate the matching configuration ii that needs to be applied to all user subgroups according to the “priority value” and the matching configuration corresponding to all user subgroups. Specifically, various schemes can be employed, such as:

(1) Select the matching configuration ii of the specified user subgroup i to apply to all user subgroups. Preferably, the user subgroup i here has the highest "priority value" among all user subgroups.

(2) Perform "comprehensive processing" on matching configurations corresponding to multiple specified user subgroups to obtain a comprehensive matching configuration ii. Preferably, the "priority value" corresponding to the plurality of user subgroups herein should be higher (such as the highest and the second highest) among all user subgroups. The "integrated treatment" here can be a compromise. E.g:

If the matching configuration ^ selected by the highest priority "user group" is Conf#5 (as shown in Figure 1), the number of downlink subframes is 9:1 than the number of uplink subframes;

If the matching configuration i ₂ selected by the next highest priority "user group" is Conf#3 (as shown in Figure 1), the number of downlink subframes is 7:3 compared to the number of uplink subframes;

Then, the matching configuration ii can be configured to configure Conf#4, and the number of downlink subframes is smaller than the number of uplink subframes.

4: 1.

Step 610: Apply the matching configuration ii to the reconfiguration area (such as a cell) to implement the reconfiguration of the proportion of the TDD uplink and downlink subframes.

After step 610, when the next reconfiguration period comes, returning to step 606, recalculating the matching configuration (^ ₂ , ...) and matching configuration ii until the grouping of the "user group" is triggered, then returning to step 602.
