Uplink Resource Aggregation for Multiple Grants in LTE Terminals

The patent segments the resource allocation process by introducing separate indication fields for different resource types (first resource indication field for grant-based resources, second resource indication field for grant-free resources). This segmentation allows the system to handle multiple grants simultaneously by clearly distinguishing and managing different resource types independently, thereby improving data transmission capability while controlling allocation complexity.

The patent adds a new dimension to resource allocation by introducing grant-free resources as a separate resource type with its own indication field. This dimensional expansion allows the system to operate in multiple resource allocation modes (grant-based and grant-free) simultaneously, enhancing overall transmission capability without proportionally increasing the complexity of traditional grant-based allocation.

The patent applies partial action by allowing the terminal to generate one or more MAC PDUs selectively based on the received grants, rather than requiring a fixed number. The system generates MAC PDUs partially (one or multiple) depending on the specific transmission needs and resource availability, improving multiplexing efficiency while avoiding the overhead associated with always generating a fixed set of MAC PDUs.

The patent changes the parameter of MAC PDU quantity from a fixed value to a variable (one or multiple) based on transmission conditions. By making the number of MAC PDUs a flexible parameter that adapts to the number of grants and data requirements, the system optimizes the balance between multiplexing efficiency and overhead, generating only the necessary number of MAC PDUs for each transmission scenario.
