BEST-EFFORT MACRO DIVERSITY

摘要

The present invention relates to a network node and a method for providing macro diversity in a radio telecommunications network comprising a radio base station providing a radio link to a mobile terminal, the radio base station comprises communication resources for supporting the radio link to the mobile terminal and for supporting transmission of data between the mobile terminal and a network node. The invention comprises: - receiving a signal from the mobile terminal; estimating a signal quality parameter for the received signal; sending a first message to the mobile terminal instructing the mobile terminal to adjust at least a first transmission parameter if the signal quality parameter is below a quality target; and if the signal quality parameter is above the quality target, and if lack of the resources prevents the radio base station to relay data between the mobile terminal and the network node, sending the first message to the mobile terminal instructing the mobile terminal to adjust the at least one transmission parameter.
