Abstract
FIELD: radio engineering communication.SUBSTANCE: invention relates to wireless communication and is intended for transmitting acknowledgement signals which include using transmission diversity. The invention discloses a method and a device for user equipment (UE) for transmitting control channel acknowledgement signals associated with a hybrid automatic repeat request process (HARQ-ACK signals) in response to receiving transport blocks (TB) transmitted from a base station. The UE conveys the HARQ-ACK information by selecting one resource from multiple resources in the control channel and by selecting a constellation point of the modulation scheme for the HARQ-ACK signal. Transmission diversity is supported using different control channel resources that are already available to the UE without configuring additional resources. Design principles are described in the method and device to optimally map the HARQ-ACK information to control channel resources and modulation constellation points for a time division duplex (TDD) system and for a frequency division duplex (FDD) system.EFFECT: high noise-immunity.18 cl 12 dwg 12 tbl
