Problems solved by technology

[0028] In the current actual deployment network, the selection timing and uplink and downlink configuration parameters of 5G NR are preset before the deployment of NR cells, and if the configuration of LTE cells changes, all NR cells should be modified and configured, otherwise Interference in mixed coverage areas of LTE and NR will increase, greatly increasing the engineering cost of 5G NR deployment

Abstract

The invention relates to a method for automatically configuring uplink and downlink time slots of a 5G NR cell, belonging to the field of fifth-generation mobile communications, including step 1: power on and start up a newly built NR cell, search and interpret signals of nearby NR cells; step 2: if the newly built NR If the cell fails to search for a valid nearby NR cell, search and interpret nearby LTE cells; Step 3: If the new NR cell fails to search for nearby NR cells and LTE cells, the new NR cell will use its default time base and uplink and downlink configuration , record the uplink and downlink time slot configuration used in the cell configuration, and the configuration of special time slots; Step 4: According to the frame positioning time base and up and down symbol configuration determined by the nearby NR cell or LTE cell or adopt the default time base and up and down configuration, Calculate the time base and uplink and downlink configuration of the newly built NR cell; Step 5: set the frame time base and uplink and downlink configuration parameters of the newly built NR cell.

Description

technical field [0001] The invention belongs to the technical field of micro base stations in the field of fifth-generation mobile communication, and specifically relates to frame timing and uplink and downlink time slot configuration of base stations. Background technique [0002] In the field of mobile communication, information is transmitted through wireless means, and the base station cannot accurately locate the position of the terminal in real time due to the movement of the terminal. The wireless frequencies used by adjacent terminals may be very close to each other, especially in the same-frequency networking scenario in time-division multiplexing mode. At the same time, due to the cost and technical limitations of the terminal implementation, the out-of-band radiation requirements of the transmitter cannot be completely eliminated. If the time between the cells is not synchronized, the signal sent by one terminal will fall into the receiver of another terminal, flo...
