Problems solved by technology

[0007] For a cell configured with SUL carriers and PUL carriers, when the terminal moves from the central area to the edge area, the quality of the PUL carrier will drop sharply. If the terminal initiates random access (RA) on the PUL carrier or wireless link The data transmission at the radio link control protocol (Radio Link Control, RLC) layer is likely to cause RA failure or reach the maximum number of retransmissions at the RLC layer due to the deterioration of the PUL carrier condition, thereby triggering a radio link failure (Radio Link Failure, RLF) process
After the terminal enters the RLF, it will reselect for cell search and Radio Resource Control (RRC) connection re-establishment, which will cause the long-term interruption of the uplink service of the terminal

Abstract

The embodiment of the invention provides a communication method and device. A terminal determines that the number of times of sending a random access request on a first uplink carrier reaches a threshold value or the number of times of retransmission on a radio link control protocol (RLC) layer of the first uplink carrier reaches a threshold value; And the terminal triggers to switch to a second uplink carrier to communicate with network equipment, and the first uplink carrier and the second uplink carrier belong to the same cell. By means of the communication method and device, triggering ofthe RLF process can be avoided.
