Title:
CHANNEL ARBITRATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/083284
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a channel arbitration method and an apparatus, where after a physical layer scheduler of a terminal device receives an uplink grant for a first SIM card, a send service priority level of the first SIM card in a front end arbiter is configured as a first predicted priority level, and PUSCH send information is configured for the front end arbiter according to the uplink grant, wherein if uplink schedule packeting is completed before an arbitration time point, the send service priority level of the first SIM card is refreshed as a MAC layer service priority level; the front end arbiter performs arbitration on a send service of the first SIM card according to the PUSCH send information and the send service priority level, and further, if the first SIM card is currently executing a voice service, and continuous arbitration fails, then fallback to a DSDS2.0 mode is triggered, and the first SIM card is allowed to independently occupy a send channel and execute the voice service. An embodiment of the present application can prevent an error in an arbitration result caused by a MAC layer service priority level being unable to be configured in time.
