1. A method comprising:

  • providing an enhanced allocation of bandwidth for a radio resource comprising an uplink radio resource; and

    allocating the radio resource using the enhanced allocation of bandwidth such a predetermined at least one resource block of the radio resource is one of left unused or blanked,where the uplink radio resource comprises a periodic channel quality indicator resource, and where allocating comprises a pre-determined at least one resource block of the periodic channel quality indicator resource is one of left unused or blanked,where the periodic channel quality indicator resource comprises at least one of a physical uplink control channel format of a second type, where the providing the enhanced allocation of bandwidth comprises selecting parameters NRB(2) and Ncs(1) such that NRB(2)NscRB+(NscRB

    Ncs(1)

    >

    (a number of simultaneous resources allocated to the at least one of the physical uplink control channel format of the second type),where the number of simultaneous resources allocated to the at least one of the physical uplink control channel format of the second type is equal to nPUCCH(2), where nPUCCH(2) is a resource index for resources used for the physical uplink control channel formats of the second type,where NscRB equals a resource block size in a frequency domain, expressed as a number of subcarriers,where NRB(2) is a bandwidth reserved for the physical uplink control channel formats of the second type, expressed in multiples of NscRB,where Ncs(1) is a number of cyclic shifts used for at least one of a physical uplink control channel format of a first type in a mixed resource block, andwhere nPUCCH(2) is a resource index for resources used for physical uplink control channel formats of the second type.
