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, wherein the identified component carriers are scheduled for Physical Uplink Shared CHannel (PUSCH) transmissions; identifying at least one of the identified component carriers for transmission of uplink control information, the at least one of the component carriers being at least partially determined by a component carrier index; encoding uplink control information into the at least one of the component carriers for transmission to the base station; determining whether a second uplink component carrier of the identified component carriers is scheduled; and precluding the second uplink component carrier from transmitting the uplink control information based on a transmission mode configured for the second uplink component carrier.
