System and method for uplink control information transmission in carrier aggregation

摘要

A method for communicating uplink control information to a base station using a user equipment is presented. The method includes identifying component carriers on the user equipment scheduled for Physical Uplink Shared CHannel (PUSCH) transmissions, and identifying at least one first ranking for each of the component carriers for transmission of uplink control information. Each first ranking is at least partially determined by whether the component carrier is configured for delay-sensitive transmissions. The method includes using the at least one first ranking to select a first component carrier for transmission of uplink control information, and encoding uplink control information into the first component carrier for transmission to the base station.

1. A method for communicating uplink control information to a base station using a user equipment, comprising:
identifying component carriers on the user equipment scheduled for Physical Uplink Shared CHannel (PUSCH) transmissions; when one or more of the component carriers is configured for non-delay-sensitive transmissions: identifying one or more of the component carriers that are configured for non-delay-sensitive transmissions, and selecting a first component carrier from the one or more of the component carriers for transmission of uplink control information; and encoding uplink control information into the first component carrier for transmission to the base station.
