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.

Abstract: This application provides a service processing method and apparatus, a terminal device, and a chip, and relates to the field of communication technologies. When the terminal device carries a primary card and a secondary card, the secondary card uses one or more antennas by default to process an uplink/downlink transmission service. When the primary card is triggered to perform neighboring cell measurement (e.g., inter-frequency inter-RAT measurement), and a measurement band is the same as an operating band of the secondary card, the primary card may select an antenna different from an antenna used by the secondary card to perform neighboring cell measurement.
