Transmission of HARQ control information from a user equipment for downlink carrier aggregation

摘要

Methods and apparatuses are provided for transmission of at least two HARQ-ACK bits. Information for at least two configured cells and information for a transmission mode for each of the at least two configured cells are received. At least one transport block is received on the at least two configured cells. The at least two HARQ-ACK bits are generated based on a number of the at least two configured cells and the transmission mode for each of the at least two configured cells. Transmission power for the at least two HARQ-ACK bits is adjusted based on a number of the received at least one transport block. The at least two HARQ-ACK bits are transmitted on a PUCCH. A transmission mode supports one transport block or up to two transport blocks.

1. A method for a User Equipment (UE) to transmit at least two Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) bits, the method comprising the steps of:
receiving information for at least two configured cells and information for a transmission mode for each of the at least two configured cells; receiving at least one transport block on the at least two configured cells; generating the at least two HARQ-ACK bits based on a number of the at least two configured cells and the transmission mode for each of the at least two configured cells; adjusting transmission power for the at least two HARQ-ACK bits based on a number of the received at least one transport block; and transmitting the at least two HARQ-ACK bits on a Physical Uplink Control Channel (PUCCH), wherein a transmission mode supports one transport block or up to two transport blocks.
