Description

A method and system for uplink resource allocation and power dynamic adjustment

technical field

The present invention relates to the communication field, in particular to an uplink resource allocation method, a method for dynamic control and adjustment of uplink power and a system thereof.

Background technique

In a cellular mobile communication system, users using the same frequency resources in each cell will interfere with each other, causing inter-cell interference and seriously affecting system capacity.

Figure 1 shows the interference situation of the uplink. BS1 and BS2 are the serving base stations of MS1 and MS2 respectively, assuming that the set of subcarriers allocated by BS1 to MS1 for uplink transmission is SC1, the set of subcarriers allocated by BS2 to MS2 for uplink transmission is SC2, and the intersection of SC1 and SC2 is SC . If SC is not an empty set, when BS2 receives the uplink signal sent by MS2, the subcarriers in the set SC will receive the uplink signal sent by MS1 at the same time. For MS2 and BS2, these signals from MS1 are interference . If the distance between MS1 and MS2 is very small, assuming that MS1 and MS2 are located in the overlapping area of the two serving cells, the interference between the cells will be very strong, which may cause BS2 to fail to correctly demodulate the uplink signal sent by MS2 .

If the inter-cell interference is severe, the system capacity will be reduced, especially the transmission capability of the cell edge users, which will affect the coverage capability of the system and the QoS (Quest of Service, quality of service request) performance of the terminal.

Step 30, the base station compares the current bandwidth occupancy rate with a preset threshold, and obtains cell load status information;

Step 40, the base station adjusts the resource allocated by the terminal within the service area and the uplink transmission power spectral density according to the obtained uplink IoT level comparison result and the cell load status information, and sends the resource configuration information and power spectral density configuration information to the the terminal.

Further, in the step 10, the uplink IoT level is determined by the base station according to the following formula: IoT _k =(N _k +I _k )/N _k , where N _k is the number received by the base station on subcarrier k I _k is the uplink interference power received by the base station on subcarrier k; IoT _k is the interference-to-noise ratio received by the base station on subcarrier k.
