Abstract

The invention provides a communication method and device. The method comprises the following steps: a terminal determines a conflict between a first transmission resource and a second transmission resource, wherein the first transmission resource is a resource for the terminal to send first information to a first network side, the first network side device corresponds to a first user identity supported by the terminal, the second transmission resource is a resource for the terminal to send second information to a second network side, and the second network side device corresponds to a second user identity supported by the terminal; the terminal sends the first information on the first transmission resource; the terminal cancels sending of the second information on the second transmission resource; or, the terminal sends the second information on a third transmission resource, and the third transmission resource is a resource before or after the second transmission resource. The methodis used for solving the problem of resource conflict of the DR-DSDS terminal due to a single Tx path.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] With the development of communication technology, many mobile terminals (such as mobile phones) have dual-card dual-standby functions. Wherein, dual-card dual-standby means that two subscriber identity module (subscriber identity module, SIM) cards are installed in a mobile phone at the same time, and the two SIM cards can be on network standby at the same time. [0003] Currently, a dual SIM dual active (DSDA) technology is applied to a mobile phone. Among them, the DSDA mobile phone itself has two sets of transceiver radio frequencies, that is, each SIM card has an independent transceiver radio frequency. However, the cost of setting two sets of transceiver radio frequencies in the DSDA mobile phone is relatively large, and the two sets of radio frequencies will occupy a large layout area and...
