Abstract

The embodiment of the present invention provides a random access failure processing method. The random access failure processing method includes the steps: when the number of times of transmitting lead codes of random access to the base station is greater than a preset number of times, determining a cells and a carrier which are used for transmitting the lead codes; and when the cell which is usedfor transmitting the lead codes is a main cell configured with a SUL (supplement UpLink) carrier and a non-SUL carrier, and if the carrier which is used to transmit the lead codes is a non-SUL carrier, transmitting a message that random access has a problem to the base station through the SUL carrier. According to the random access failure processing method, when determining that the non-SUL carrier of the main cell has a problem, since the main cell is also configured with the SUL carrier and the performance of the SUL carrier is generally better than the performance of the non-SUL carrier,when the SUL carrier has a problem, the SUL carrier may be no problem, so that the message that random access has a problem can be transmitted to the base station through the SUL carrier so as to guarantee that the that of the base station can receive the problem in time and then process the problem in time.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a random access failure processing method, a random access failure processing device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In LTE (Long Term Evolution, long term evolution), user equipment can initiate random access to a base station on a carrier of a cell. [0003] In NR (New Radio, new air interface), a SUL (supplement UpLink, supplementary uplink) carrier is introduced to enhance uplink coverage. In addition, the SUL carrier does not correspond to a single cell, but is paired with a non-SUL carrier to correspond to a cell. [0004] At present, the processing method for initiating random access failure in LTE is mainly applicable to the case where a cell is configured with a carrier, but for the case where a cell in NR is configured with a SUL carrier and a non-SUL carrier, there is no appropriate m...
