Abstract

Automatically adjust the size of a Physical Uplink Control Channel, PUCCH, of an uplink communication subframe. In a particular embodiment, the size of a semi-static region of the PUCCH is adjusted. The adjustment is based on a utilization factor of the PUCCH over a time period. The adjustment can also be based on the connection factor (connections between the wireless terminals and the cell) and/or based on the utilization factor of a PUSCH (Physical Uplink Shared Channel). The result is an efficient resource utilization on the PUCCH, and a properly dimensioned PUCCH region.
