Abstract

A method of adapting user equipment uplink transmission power for user equipment performing soft handover in a heterogeneous wireless telecommunication network in which at least one network access node provides a first region of radio coverage, and at least one low power network access node provides a second region of radio coverage smaller than the first region of radio coverage. A network control node and computer program product operable to perform that method. The method comprises: receiving a request from the user equipment to add a new network access node or low power network access node to its active set; determining whether addition of the new network access node or low power network access node will change the active set to a mixed active set including both at least one network access node providing a first region of radio coverage and at least one low power network access node providing a second region of radio coverage smaller than the first region of radio coverage; and, if so transmitting an indication to the user equipment to adapt its uplink transmission power by increasing the transmission power of at least one uplink communication channel if the request to add the new network access node or low power network access node to its active set is approved. Aspects and embodiments described recognise that heterogeneous networks may cause problems to user equipment operating according to soft handover procedures and can assist with maintaining overall network efficiency in cases where problems might otherwise occur.
