Example embodiments are directed to methods of reducing inter-cell interference in wireless networks using successive interference cancellation (SIC). Example embodiments use inter-cell cooperation between cells and/or sectors to successfully decode their associated users' data signals and pass on the decoded data signals to other cells/sectors in order to reduce inter-cell interference and allow for improved decoding of users' data signals. Example embodiments include passing the decoded data signals via the backhaul. Example embodiments also include static and dynamic ordering of user data signals in conjunction with the application of SIC.

Various methods and devices are provided to address the need for improved cooperation-based signal processing. In a first method, network equipment determines (801) a set of dominant interferers for a wireless transmission and requests (802) user-plane data corresponding to each dominant interferer in the set of dominant interferers. The network equipment then processes (803) a received signal corresponding to the wireless transmission to extract the information transmitted. This processing uses at least some user-plane data corresponding to at least one dominant interferer in the set of dominant interferers.

Systems and methods are disclosed for reusing resources of a wireless network. Radio communications resources of the wireless network are divided into partitions. A system described herein allows access to resources in the first partition by a first set of users for primary communications on the first partition, and allows access to resources in the first partition by a second set of users for secondary communications on the first partition. The control system also allows access to resources in the second partition by the second set of users for primary communications on the second partition, and allows access to resources in the second partition by the first set of users for secondary communications on the second partition.

Various methods and devices are provided to address the need for improved mobile communications in heterogeneous networks. In one method, an anchor-cell transceiver node communicates with a mobile device via a primary link. The anchor-cell transceiver node conveys information for the mobile device to the mobile device by routing at least a portion of the information to the mobile device via a secondary-cell transceiver node.

Various methods and devices are provided to address the need for improved inter-carrier load balancing. In one method, network equipment determines (101) an achievable rate for a plurality of wireless devices on each carrier of a plurality of carriers. Inter-carrier load balancing is performed (102) by the network equipment by assigning a carrier of the plurality of carriers to each wireless device using the determined achievable rate of that wireless device on each carrier.

A base station transmitter for a broadcast/multicast single frequency network may include a base station component configured to randomize a phase of the signal for the base station transmitter to transmit, wherein the base station transmitter is configured to transmit a signal having a frequency common to a frequency of a signal sent by another base station component in the network. A method for improving performance of single frequency networks may include transmitting single frequency signals from base stations with pseudo-random phases including in the signals, data that permits a receiver compatible with the network to synchronously replicate the pseudo-random phases used in the transmission of the single frequency signals.
