Claim of US Patent No. 10,694,524

1. A communication apparatus which is operable to communicate with at least one of a first, bandwidth limited, type user equipment (UE) and a second type UE, the communication apparatus comprising:a processor; and
a transceiver,
wherein the processor is configured to assign a first frequency resource for a first physical uplink control channel (PUCCH) for the first, bandwidth limited, type UE, wherein the first PUCCH is initially carried by a first narrowband that is small relative to a transmission bandwidth in a cell, and wherein the first PUCCH is subsequently, following a retuning by the first, bandwidth limited, type UE, carried by a second narrowband that is small relative to the transmission bandwidth in the cell,
wherein the second narrowband is different from the first narrowband,
wherein, for a PUCCH transmission for the first, bandwidth limited, type UE, a resource block to be used in the first narrowband is at a first position within a total number of resource blocks in the transmission bandwidth in the cell, and wherein a resource block to be used for said PUCCH transmission for the first, bandwidth limited, type UE in the second narrowband is at a second position within the total number of resource blocks in the transmission bandwidth in the cell that is equal to the total number of resource blocks in the transmission bandwidth in the cell less the first position, and
wherein the processor is further configured to assign a second frequency resource for a second physical uplink control channel (PUCCH) for the second type UE.
