Abstract
The specification and drawings present a new method, apparatus and software related product for avoiding UL interference in a victim LPN such as femtocell using DRX by the LPN coordinated with the UL DTX of UEs to the LPN and to one or more HPNs such as NBs (or Home NB), e.g., in HSPA systems. The victim LPN may start DRX having ON and OFF periods. Then the LPN sends information about DRX to its UEs (LUEs) communicating with the LPN, and to one or more network elements such as aggressor HPNs' RNCs. The network element(s) are adapted to identify and configure aggressor UEs (HUEs) communicating with one or more HPNs of the network for coordinating ON and OFF periods of the DRX by the LPN with transmissions of the LUEs and the HUEs to avoid interference during the OFF periods of the DRX in the LPN.
