Method and apparatus for controlling transmission power

摘要

A method and apparatus is provided for uplink transmission power control in discontinuous data transfer in a wireless communication network. In situations where a user equipment (UE) receives a transmission power control (TPC) command from a base station for an uplink shared or control channel (PUSCH or PUCCH) but does not receive an uplink resource allocation, the power may exceed prescribed limits. Therefore the UE calculates its transmission power based on currently used bandwidth, and a check is made as to whether a transmission power limit has been reached based on the calculated transmission power. The calculation can use current resource block allocation or pre-defined (e.g. minimum or maximum) allocation. The power calculation can alternatively use data relating to the format of the channel e.g. the number of bits used for channel quality information and HARQ.
