Abstract
A user equipment and a method for identifying a resource to use for a transmission of control information on a physical uplink control channel, PUCCH, format 3 involve receiving a resource index from a serving radio base station, and identifying the resource to use for the transmission of the control information in a subframe based on the received resource index, wherein the identified resource is within a same confined set of physical resource blocks regardless of if a normal or a shortened PUCCH format 3 is used in the subframe.
Claims24
A method in a user equipment of a wireless communication system, for identifying a resource to use for a transmission of control information on a physical uplink control channel, PUCCH, format 3, the method comprising:
- receiving a resource index from a serving radio base station, and
- identifying the resource to use for the transmission of the control information in a subframe based on the received resource index, wherein identifying the resource includes identifying a physical resource block,
- wherein for both a normal PUCCH format 3 and a shortened PUCCH format 3 used in the subframe the physical resource block is identified based on NSF,0PUCCH, which is a number of orthogonal sequences available for a physical resource block in a first time slot of the subframe.
A user equipment for a wireless communication system, configured to identify a resource to use for a transmission of control information on a physical uplink control channel, PUCCH, format 3, the user equipment comprising:
- a receiving unit adapted to receive a resource index from a serving radio base station, and
- an identifying unit adapted to identify the resource to use for the transmission of the control information in a subframe based on the received resource index, wherein identifying the resource includes identifying a physical resource block,
- wherein for both a normal PUCCH format 3 and a shortened PUCCH format 3 used in the subframe the physical resource block is identified based on NSF,0PUCCH which is a number of orthogonal sequences available for a physical resource block in a first time slot of the subframe.
