Method for managing heterogeneous base stations in a wireless network

摘要

A method and devices are provided to enable operation while experiencing reduced interference of at least two base stations in a wireless network wherein at least one of base stations is deployed in a femto deployment configuration and at least one of the others is deployed in a different deployment category. The method comprises preventing the usage of at least one radio resource selected from among sub-carriers comprised within a radio channel and/or time-domain resource, from one of the at least two base stations.

1. A method for distributing resources among categories of cell types, the method comprising:
dividing a superframe domain into at least a first frame, a second frame, a third frame, and a fourth frame; dividing the first frame into first set of subframes; dividing the second frame into second set of subframes; dividing the third frame into third set of subframes; dividing the fourth frame into fourth set of subframes; and partitioning a frequency domain into a reuse 1 zone, a reuse 2/3 zone, and a reuse 1/3 zone; allocating resources in the reuse 1 zone as follows: allocating a first subframe in the first set of subframes to additional resources for category 1 and category 2 control channels; allocating a first subframe in the second set of subframes to dedicated resources for category 3 control channels; allocating a first subframe in the third set of subframes to the additional resources for the category 1 and the category 2 control channels; and allocating a first subframe in the fourth set of subframes to additional resources for the category 3 control channels; allocating resources in the reuse 2/3 zone as follows: allocating the first subframe in the first set of subframes to additional resources for dedicated resources for category 2 control channels; allocating the first subframe in the second set of subframes to the dedicated resources for category 3 control channels; allocating the first subframe in the third set of subframes to the dedicated resources for the category 2 control channels; and allocating the first subframe in the fourth set of subframes to the additional resources for the category 3 control channels; and allocating resources in the reuse 1/3 zone as follows: allocating the first subframe in the first set of subframes to dedicated resources for the category 1 control channels; allocating the first subframe in the second set of subframes to additional resources for the category 1 control channels; allocating the first subframe in the third set of subframes to the dedicated resources for the category 1 control channels; and allocating the first subframe in the fourth set of subframes to the additional resources for the category 1 control channels.
