Abstract:
1. 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, 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, and wherein identifying the resource comprises identifying an orthogonal sequence based on an orthogonal sequence index n where n PUCCH is the received resource index, and N SF,1 PUCCH is a number of orthogonal sequences available for a physical resource block in a second time slot of the subframe.
