The resources within a certain CC may also be partitioned into smaller chunks for similar interference mitigation purposes [6].
When the FAP 2 applies TBF for interference mitigation purposes in FUE 1, beamforming gain in the second femtocell vanishes since component channels sum up with random phases.
Furthermore, we propose a method whereby user terminals can maintain a controlonly connection to an adjacent femtocell for interference mitigation purposes.
Details of this compensation scheme are given in Section 3. Furthermore, the FBSs may also adjust their power to control their transmission range communication if the MBS requests coverage enhancement and for interference mitigation purposes.
In, e.g., [8, 9], the authors proposed the use of dynamic frequency re-use, whereas in [10, 11] power control was utilized for downlink and uplink cross-layer interference mitigation purposes, respectively.
When the FAP in better condition selects the TBF weights for interference mitigation purposes (i.e., altruistic beamforming), the stochastic behavior of the desired signal and the interference that the FUE in disadvantageous situation perceives can be approximated as χ2distributed RVs with 4 and 2 degrees of freedom, respectively.
The solid lines in Figure 3 correspond to the situation in which 2-bit mode 1 altruistic beamforming has already been applied in FAP 2 for interference mitigation purposes at FUE 1. Now, using SR-based channel-aware scheduling we can provide to FUE 1 periods of low interference, increasing as a consequence the likelihood of experiencing higher instantaneous data rates.
The common message in a unicast-multi-cast system carries public information intended as a whole to all users in the system, while the common message s12 in RS encapsulates parts of private messages, and is not entirely required by all users, although decoded by the two users for interference mitigation purposes [12].
We therefore propose an iterative estimator to provide accurate channel and data estimation which is of significant importance for further multipath interference cancelation purpose.
Therefore, it can be demonstrated that the iterative estimator is capable of providing accurate channel and data estimation results for multipath interference cancelation purpose.
