The specific line i can derive the Fixed_Mds according to the current line conditions according to FIXED_RATE_DOWNSTREAM and FIXED_RATE_UPSTREAM respectively. i) with Fixed_Mus(i), and the entire coordination group is based on the value of Fixed_Mds(1)...Fixed_Mds(n) and Fixed_Mus(i)...Fixed_Mus(n) for all lines in the coordination group (total of n lines) to get Fixed_Mds (GROUP) and Fixed_Mus(GROUP). Each line in the coordination group can take the unified Fixed_Mds and Fixed_Mu, namely Fixed_Mds (GROUP) and Fixed_Mus (GROUP).

The dynamic time allocation module (or dynamic resource management module DRA) can derive the number of downlink symbols required to reach the downlink fixed bandwidth corresponding to the current line condition from the downlink fixed bandwidth (FIXED_RATE_DOWNSTREAM) and the uplink fixed bandwidth (FIXED_RATE_UPSTREAM) of the specific line, respectively.

For a downlink or uplink fixed bandwidth, for a coordination group or a vectoring group, the communication conditions of each line may be different, so the calculated Fixed_Mds or Fixed_Mus may be different; when there are different Fixed_Mds or Fixed_Mus, the coordination group is taken. The largest Fixed_Mds or Fixed_Mus is the Fixed_Mds or Fixed_Mus of the coordination group, namely:

Fixed_Mds(GROUP)=MAX[Fixed_Mds(1),...,Fixed_Mds(n)] [3]

Step 2: Based on the DTA control parameters, the dynamic time allocation module (or the dynamic resource management module DRA) monitors the uplink and downlink traffic information of each line in the coordination group or the vectoring group, and determines whether to adjust the TDD frame configuration parameters. If the TDD frame configuration parameter to be updated is to be adjusted, the transceiver module of the central office acquires the TDD frame configuration parameter to be updated and the related DTA control parameter, and sends the TDD frame configuration information to the terminal.

The following describes the control method of TDD frame configuration parameter adjustment in detail:

1. Priority based on specific line traffic requirements

4 is a manner based on a particular line priority, in accordance with an embodiment of the present invention. In this embodiment, in the case that the adjustment parameters of each line DTA are met (for example, the number of downlink symbols Mds in the TDD frame is not less than Mds-min, and the number of uplink symbols is not less than Mus-min), the traffic of the specific line is prioritized. demand. For line 1 and line 2, it is assumed that the priority of line 1 is higher than that of line 2. In the case where the uplink and downlink traffic demands of line 1 and line 2 collide, priority is given to the uplink and downlink traffic demand of line 1, according to the upper and lower lines of line 1. The traffic demand is determined to determine the TDD frame configuration parameter Mds or Mus. As shown in FIG. 4, the priority of line 1 is greater than that of line 2, and in the n+xth TDD frame period, the downlink traffic demand of line 1 is adjusted according to the downlink traffic demand of line 1 (Note: the expected Mds of line 1 in the corresponding figure), line 2 The upstream traffic demand cannot be met; in the n+x+y TDD frame period, only when the downlink traffic demand of the line 1 is reduced, the uplink traffic demand of the line 2 (the expected Mds of the line 1 in FIG. 4) can be adjusted. .

2. Line-based traffic first-come first-served mode

FIG. 5 is a first-come, first-served manner of line-based traffic according to an embodiment of the present invention. In this embodiment, in the case that the adjustment parameters of each line DTA are met (for example, the number of downlink symbols Mds in the TDD frame is not less than Mds-min, the number of uplink symbols is not less than Mus-min), which line of traffic first Preemption first. For example, the current system TDD frame configuration parameter Mds is adjusted according to the uplink and downlink traffic demand of the line 1. If the uplink and downlink traffic demand of the line 2 conflicts with the uplink and downlink traffic demand of the current line 1, the uplink and downlink of the line 1 are still satisfied. The traffic demand shall prevail. Under the premise of not affecting the upstream and downstream traffic demand of the line 1, the Mds shall be adjusted to meet the requirements of the uplink and downlink traffic adjustment of the line 2; only when the traffic demand of the line 1 changes, the current line 1 is not affected. In the case of the traffic demand situation, the adjustment of the TDD frame configuration parameter Mds is performed according to the uplink and downlink traffic demand of the line 2. As shown in FIG. 5, during the n+xth TDD frame period, the downlink traffic demand of line 1 (note: the expected Mds of line 1 in the corresponding figure) cannot be satisfied due to the length of the number of symbols required for the uplink traffic of line 2. The number of downlink symbols actually allocated is the maximum number of downlink symbols that can be taken under the premise that the length of the number of symbols required for the uplink traffic of the line 2 is satisfied; in the n+x+y TDD frame period, the line 2 is uplinked. The traffic demand is reduced and the uplink symbol is vacated, and the downlink traffic demand of the line 1 is consistent with the traffic demand at the n+xth TDD frame period, and the actually allocated downlink symbol number can be correspondingly increased.

3. The way to control by configuring different types of uplink and downlink bandwidth for different lines

FIG. 6 is a schematic diagram of adjusting the bandwidth of different configurations based on uplink and downlink according to an embodiment of the present invention. In this embodiment, when the DTA adjustment limit parameter is met, for example, the number of downlink symbols Mds in the TDD frame is not less than Mds- Min, the number of uplink symbols is not less than Mus-min), satisfies the requirements of fixed bandwidth of each line, and/or satisfies the requirements for guaranteed bandwidth of each line (ie, when the traffic demand of a line is greater than or equal to the guaranteed bandwidth, the bandwidth provided is required) Not less than the guaranteed bandwidth requirement of the line; when the traffic demand of a line is less than the guaranteed bandwidth, the excess bandwidth may be considered for use by other lines), and in the case of meeting the fixed bandwidth and/or guaranteed bandwidth requirements, The traffic demand is considered to adjust the TDD frame configuration parameters. As shown in FIG. 6 , the Mds-fix indicates the length of the downlink symbol number corresponding to the fixed bandwidth of the downlink in the current reachable rate, and the Mds-gua indicates that the guaranteed bandwidth of the downlink configuration of the line is currently reachable. The length of the corresponding downlink symbol number in the case of the rate; Mus-fix indicates the length of the uplink symbol number corresponding to the fixed bandwidth of the uplink in the current reachable rate, and Mus-gua indicates the uplink configuration of the line. The length of the corresponding number of uplink symbols that the bandwidth is guaranteed in the current reachable rate case. Among them, Mds-fix and Mus-fix correspond to Fixed_Mds(GROUP) and Fixed_Mus(GROUP) respectively, and the calculation formulas are as shown in [3] and [4]; Mds-gua and Mus-gua of each line and Commit_Mds respectively Commit_Mus corresponds to the calculation formula as shown in [5], [6]. Since the fixed bandwidth should be reserved with or without data traffic, the actual number of downlink symbols of the TDD frame of the line should be no less than Mds-fix, the number of uplink symbols should be no less than Mus-fix; and the guaranteed bandwidth is no data traffic demand. The bandwidth that can be given out, therefore, the actual number of downlink symbols of the TDD frame may be smaller than Mds-gua, and the number of uplink symbols may be smaller than Mus-gua. At the n+xth TDD frame period, the downstream traffic demand of line 1 (note: the expected Mds of line 1 in the corresponding figure) exceeds its Mds-gua, since the upstream traffic demand of line 2 corresponds to its Mus-gua Within the scope, it is necessary to preferentially meet the upstream traffic demand of line 2, and the realized Mds cannot meet the downlink traffic demand of line 1; in the n+x+y TDD frame period, the downlink traffic demand of line 1 is satisfied (the corresponding When the number of downlink symbols is Mds), the number of uplink symbols corresponding to line 2 is Mus (Note Mus=Mf-Mds-1, and Mf is the total number of symbol periods occupied by TDD frames) enough to satisfy the uplink traffic demand of line 2, although Mus is smaller than the Mus-gua of line 2, so the actual downlink number of symbols is allocated to meet the downlink traffic demand of line 1; in the n+x+y+z TDD frame period, the uplink traffic demand of line 2 increases and corresponds The number of uplink symbols is required to be within the Mus-gua of line 2, so the actual number of downlink symbols is adjusted according to the upstream traffic demand of line 2.

4. Controlling the different priorities based on the uplink and downlink directions

FIG. 7 is a schematic diagram of different uplink and downlink directions corresponding to different priorities according to an embodiment of the present invention. In this embodiment, when the uplink and downlink bandwidth adjustment requirements of higher priority of each line are met, for example, each line is fixed. Bandwidth requirements (such as greater than the minimum bandwidth, that is, the number of downlink symbols Mds in the TDD frame is not less than Mds-min, the number of uplink symbols is not less than Mus-min), and/or meet the guaranteed bandwidth requirement, when the upstream and downstream traffic demands conflict At the same time, the adjustment of the TDD frame configuration parameter Mds is performed according to different priorities of the uplink and downlink directions. For example, if the priority of the downlink traffic is higher than the priority of the uplink traffic, the adjustment of the TDD frame configuration parameter Mds is performed to meet the downlink traffic demand. As shown in FIG. 7, in the n+xth TDD frame period, since the downlink 1 downlink priority is higher than the uplink priority of the line 2, the downlink traffic demand of the line 1 is adjusted, and the uplink traffic of the line 2 is adjusted. The demand (Note: the expected Mus of line 2 in the corresponding figure) cannot be satisfied due to the low priority in the uplink direction; in the n+x+y TDD frame period, the priority in the downlink direction of line 2 is higher than the priority in the uplink direction. It is adjusted according to the downstream traffic demand of line 2, and its upstream traffic demand (Note: the expected Mus of line 2 in the corresponding figure) cannot be satisfied due to the low priority in the uplink direction.

5. Control based on different priority service traffic requirements

FIG. 8 is a schematic diagram of performing control according to different priority service traffic requirements according to an embodiment of the present invention.
