Uplink control data transmission

摘要

Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

1. A method for providing feedback information on a processing structure, the method comprising:
generating a set of input bits associated with the feedback information, wherein the feedback information comprises a plurality of acknowledgement/negative acknowledgement (ACK/NACK) bits corresponding to a plurality of component carriers; encoding the set of input bits to create an encoded set of output bits; scrambling the encoded set of output bits using a scrambling sequence to create a set of scrambled output bits, wherein the scrambling sequence is derived as a function of at least one of the following: an identity of a wireless transmit and receive unit associated therewith or one or more cell identities; modulating the set of scrambled output bits to create a block of modulated symbols; applying a spreading code to the block of modulated symbols, wherein the spreading is applied after creating the block of modulated symbols, and wherein the spreading code is selected based on a physical uplink control channel (PUCCH) resource index; and transmitting the block spread modulated symbols corresponding to the ACK/NACK bits on a PUCCH.
