transmissão de informações de realimentação em sistemas de múltiplas portadoras e determinar recursos de ack/nack de uplink a partir de cce de downlink da concessão de downlink.

摘要

Techniques for sending feedback information for multi-carrier operation are described. In an aspect, feedback information for data transmissions on multiple downlink carriers may be sent on at least one uplink resource determined based on at least one downlink resource used to send at least one downlink grant for the data transmissions. In another aspect, feedback information for data transmissions on multiple downlink carriers may be sent with reduced or no orthogonal spreading to enable more feedback information to be sent. In yet another aspect, feedback information for data transmissions on multiple downlink carriers may be sent with channel selection. A UE may send a transmission of at least one signal value on at least one resource to convey acknowledgement (ACK) information for data transmissions on multiple downlink carriers.; The signal value(s) and resource(s) may be determined based on the content of the ACK information.
