Title:
通信システムにおける信号の反復転送
Document Type and Number:
Japanese Patent JP5705942
Kind Code:
B2
Abstract:
Methods and apparatuses for a User Equipment (UE) to transmit an acknowledgement signal over multiple Transmission Time Intervals (TTIs). The acknowledgement signal is in response to a data packet reception and is transmitted in a different resource in each of the multiple TTIs, if the data packet reception is through a scheduling assignment, or is transmitted in the same resource in each of the multiple TTIs, if the data packet reception is periodic. The UE transmitting an acknowledgement signal over multiple TTIs should not transmit additional acknowledgement signals in subsequent TTIs before the initial acknowledgement signal transmission is completed. The UE should also not transmit data signals or other control signals in the same or subsequent TTIs before completing transmission of an acknowledgement signal over multiple TTIs.
