  • Scheduling downlink data with multiple slot feedback channel configuration in wireless communication systems
    Patent number: 11539466
    Abstract: The described technology is generally directed towards scheduling downlink transmissions using orthogonal resources (that is, resources that avoid or at least reduce interference) when a network configures a user equipment (UE) with a multiple slot configuration to repeat the HARQ-ACK information for a transmission. By using orthogonal resources, a downlink transmission can be scheduled in consecutive time slots instead of waiting for the repeated HARQ-ACKs to complete.

  • Using constraint programming to set resource allocation limitations for allocating resources to consumers
    Patent number: 11539635
    Abstract: Resource allocation limitations include resource limits and resource guarantees. A consumer is vulnerable to interruption by other consumers if using more resources than guaranteed. Resources are designated and/or assigned to consumers based on resource limits and resource guarantees. A constraint programming (CP) solver determines resource limits and resource guarantees that minimize vulnerability and/or vulnerability cost based on resource usage data. A CP data model includes limit elements, guarantee elements, and vulnerability elements. The CP data model further includes guarantee-vulnerability constraints, which relies on exceedance distributions generated from resource usage data for the consumers. The CP data model declaratively expresses combinatorial properties of a problem in terms of constraints. CP is a form of declarative programming.
