FIELD: radio engineering, communication.
SUBSTANCE: method is intended for association biasing at a mobile device in a heterogeneous network (HetNet). The method can include the mobile device receiving coordination set information from a macro node in the HetNet. The coordination set information can include at least one low power node (LPN) identifier of at least one LPN. The mobile device can receive a request from the macro node to apply a specified reference signal (RS) biasing. The mobile device can apply the specified RS biasing to an LPN RS measurement derived from a LPN RS received from an LPN having an LPN identifier in the received coordination set information. The mobile device can associate the mobile device with the LPN when the LPN RS measurement with the specified RS biasing exceeds an association threshold.
EFFECT: reduced noise, improved capacity in active zones or on boundaries between service zones of macro nodes.
