Adaptation of receiver settings in a heterogeneous network

摘要

Techniques are described for adapting receiver settings used by a mobile terminal operating in a heterogeneous network comprising macro cells and pico cells with overlapping coverage areas. A first set of subframes is allocated to the pico cells for downlink transmissions to a mobile terminal in a link imbalance zone. The mobile terminal acquires information about the subframe allocation and uses the subframe allocation information to select the signals used for adapting receiver settings used when operating in the link imbalance zone.

1. In a heterogeneous network including macro cells and pico cells with overlapping coverage, a method implemented by mobile terminal of adapting receiver settings to receive downlink transmissions from a pico cell, said method comprising:
establishing a connection with the pico cell; receiving subframe allocation information from the network indicating a first subset of subframes reserved for downlink transmissions by the pico cell to a mobile terminal operating in a link imbalance zone; adapting a first receiver setting for a receiver parameter based on signals transmitted only in the first subset of subframes, and adapting a second receiver setting for said receiver parameter based on signals transmitted in a second subset of subframes, wherein said first setting is for use by said mobile terminal when operating in a link imbalance zone; and receiving and decoding data transmitted in the first subset of subframes by the pico cell using said first receiver setting for said receiver parameter and receiving and decoding data transmitted by a neighboring macro cell in said second subset of subframes using said second receiver setting for said receiver parameter when the mobile terminal is operating in a link imbalance zone.
