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.

A system and kit for dissipating heat generated by a motor assembly and methods for manufacturing and using same. The motor assembly includes a housing that defines an internal chamber. The internal chamber communicates with an air inlet and an air outlet each being formed in the housing, and can at least partially receive motor inner workings. A pump assembly can be included in the internal chamber for generating an air flow during operation of the motor assembly. The pump assembly can draw air into the internal chamber via the air inlet, generating an air flow within the internal chamber. The air drawn into the internal chamber is applied to the motor inner workings, and the air heated by the motor inner workings is expelled from the internal chamber via the air outlet. Thereby, the air flow advantageously can cool the motor assembly as the air traverses the internal chamber.
