Interference Reduction Through Cell Activation Methods in Heterogeneous Networks

摘要

Apparatus, methods, computer program products, and software are disclosed providing reduction of interference occurring sometime after a capacity booster cell activates, where a coverage area of a capacity booster cell is at least partially within a coverage area of a coverage cell. Techniques include handing off user equipment from the coverage cell to the capacity booster cell, creating by the capacity booster cell scheduling gaps in subframes of radio frames and scheduling user equipment connected to the capacity booster cell in the subframes not in the gaps, scheduling communications for user equipment connected to the coverage cell in the gaps, and performing one or more operations to reduce interference with the capacity booster cell for uplink transmissions from user equipment to the coverage cell.

主权项

1. A method, comprising:
in response to cell activation of a capacity booster cell, determining users in a coverage area of the capacity booster cell; determining an order of handing off user equipment from a coverage cell to the capacity booster cell based on one or more channel performance metrics; and handing off at least one user equipment according to the order from the coverage cell to the capacity booster cell.
