Abstract
Embodiments of this application disclose a channel arbitration method and an apparatus. After receiving an uplink grant for a first SIM card, a physical layer scheduler of a terminal device configures a transmission service priority of the first SIM card in a front-end arbiter as a first predicted priority, and configures PUSCH transmission information for the front-end arbiter based on the uplink grant, where if packeting for uplink scheduling is completed before an arbitration time point, the transmission service priority of the first SIM card is updated to a service priority of a MAC layer; the front-end arbiter arbitrates a transmission service of the first SIM card based on the PUSCH transmission information and the transmission service priority; and further, if the first SIM card is performing a voice service and the arbitration continuously fails, fallback to a DSDS 2.0 mode is triggered.
