As shown in Figure 5, this embodiment takes a multi-carrier synchronous TDD code division multiple access communication system as an example. The wireless resources that can be scheduled by the wireless access device and the mobile device include uplink and downlink transmission time slots, traffic channel carrier frequency, traffic channel extension The number of frequency code channels, transmission power, channel coding and modulation methods, etc., but not limited thereto. For example, if the wireless communication system adopts a smart antenna system, the user's azimuth (airspace) information is also a factor that can be considered when scheduling and allocating wireless resources.

For the sake of simplicity, in this embodiment, the resources available for scheduling and allocation in a multi-carrier synchronous TDD code division multiple access communication system only include the two-dimensional resources of uplink and downlink traffic channel transmission time slots and traffic channel carrier frequency as an example. . The schematic diagram of its frame structure is shown in Figure 6. The time slot marked "#" in the figure is a special time slot occupied by the broadcast channel, that is, the uplink and downlink control channels. The time slot 0 marked "↓" in Figure 6 is timely Slot 1 is a downlink time slot for downlink traffic channels, and time slots 2 and 3 marked as "↑" in FIG. 6 are uplink time slots for uplink traffic channels. The frequency points supported by the wireless access device and the mobile device are shown in Figure 6. The wireless access device supports a total of 6 frequency points from A to F, and the mobile device supports a total of 4 frequencies from C to F. Frequency.

The wireless resource automatic configuration method in this embodiment includes the following steps:

In the first step, the wireless access device and the mobile device of the multi-carrier synchronous TDD code division multiple access communication system respectively initialize a schedulable resource list. Here, in the case that the wireless access device can only use downlink time slot 0, and all 5 frequency points from frequency point A to frequency point F can be used, the priority of the frequency points decreases in order from A to F, and, as The mobile device can use uplink time slot 2 and time slot 3, and the priority of time slot 2 is higher than that of time slot 3, and supports a total of 4 frequency points from C frequency point to F frequency point, and the case that the frequency points have the same priority will be described as an example. But it is not limited to the above cases.

In the second step, the wireless access device and the mobile device requiring access exchange information on the access channel, and negotiate to determine that the configurable resource intersection range between the wireless access device and the mobile device is: only time slot 0 can be used for downlink services, and time slot 0 can only be used for uplink services. The business channel can use time slot 2 or time slot 3, and the optional frequency range of the uplink and downlink channels is C frequency point to F frequency point, a total of 4 frequency points.

In the third step, the wireless access device detects the uplink interference of the four frequency points C frequency point to F frequency point in time slot 2 and time slot 3. Here, the estimated time frequency proposed by the FCC (Federal Communications Commission of the United States) can be used. The method of "interference temperature" in the window is used to measure the degree of interference at certain frequency points in a specific time slot.

Here, the method proposed by the FCC to estimate the "interference temperature" within the time-frequency window can also be used to measure The degree of interference that exists at certain frequencies in a specific time slot. As shown in FIG. 8 , in this embodiment, the mobile device detects that the frequency points D and E in time slot 0 are severely interfered, and frequency points C and F have no interference in time slot 0 as an example for illustration.

In the fifth step, the wireless access device and the mobile device interact with each other detected interference situations, and formulate the priority of each resource block in the configurable resource intersection according to the resource allocation priority set in the first step (number The larger the priority, the higher the priority), as shown in Table 1 and Table 2:

Table 1 Uplink channel resource block priority

Resource block serial number Resource block configuration status priority 1 C frequency point, time slot 2 10 2 E frequency point, time slot 2 9 3 F frequency point, time slot 2 8 4 C frequency point, time slot 3 7 5 E frequency point, time slot 3 6 6 F frequency point, time slot 3 5 7 D frequency point, time slot 2 2 8 D frequency point, time slot 3 2 9 Other time-frequency block resources 0

Table 2 Downlink channel resource block priority

Resource block serial number Resource block configuration status priority 1 C frequency point, time slot 0 10 2 F frequency point, time slot 0 9 3 D frequency point, time slot 0 2 4 E frequency point, time slot 0 2 5 Other time-frequency block resources 0

In the sixth step, in the case that the uplink and downlink traffic channels each require two resource blocks to meet the transmission rate requirement, the wireless access device and the mobile device are arranged according to the priority in the fifth step, and the actual resource allocation scheme is negotiated and determined as follows: The mobile device transmits uplink service data from two frequency points C and E in time slot 2, and the wireless access device transmits downlink service data from two frequency points C and F in time slot 0.

In the seventh step, the wireless access device and the mobile device conduct business communication according to the actual resource allocation plan determined in the sixth step, and at the same time, the wireless access device sets the C and F frequency points of time slot 0 to be reassignable to other mobile devices. Equipment.

In the ninth step, when the CQI index of the uplink or downlink channel is lower than the threshold and lasts for a certain period of time, turn to the third step, and the wireless access device and the mobile device renegotiate to determine the resource allocation plan; and

In the tenth step, when the business communication ends, the wireless access device and the mobile device release the occupied time-frequency resources, and the wireless access device sets the time slot and frequency point used to be free, and can be allocated to other mobile devices for use at this time.
