Managing Transmitter Collisions

摘要

Various embodiments implemented on a mobile communication device (e.g., a multi-SIM-multi-active communication device) mitigate degraded transmit performance typically experienced by a lower-priority subscription during a Tx collision event in which a higher-priority subscription receives a shared Tx resource of the mobile communication device to the exclusion of the lower-priority subscription. Specifically, in various embodiments, a processor of the mobile communication device may determine when an upcoming transmission of the lower-priority subscription will collide with a scheduled transmission of the higher-priority subscription (i.e., may determine when a Tx collision event will occur between the subscriptions) and may implement one or more Tx collision management strategies in response to determining that the lower-priority subscription's upcoming transmission will collide with a transmission of the higher-priority subscription, thus improving the lower-priority subscription's overall performance.

主权项

1. A method performed by a mobile communication device for managing potential transmitter collisions of a first subscription, comprising:
determining a first time at which a scheduling request (SR) transmission of the first subscription is scheduled to occur; determining a second time at which a packet transmission of the first subscription is scheduled to occur based on the first time; determining a transmission schedule of a second subscription during the second time; determining whether the packet transmission will collide with a transmission of the second subscription based on the transmission schedule of the second subscription; and implementing a transmit (Tx) collision management strategy for the first subscription in response to determining that the packet transmission of the first subscription will collide with the transmission of the second subscription.
