摘要： Systems and techniques for managing interference between pico cells in a pico cluster. Pico eNodeBs are configured in groups for each of a plurality of UEs, based on factors such as signal to noise ratio and geographic location. All signals from UEs may be measured by all eNodeBs in the cluster, but a pico group decodes packets only of UEs associated with the pico group. Decoded packets are exchanged between pico groups, and when a pico group is unable to decode packets of an associated UE, is uses the decoded packets received in exchanges to reconstruct an interference signal. The interference signal is subtracted from the received signal and the resulting received signal is used to decode the packets of the UE.

摘要： In an example method of scheduling mobile users, mobile users are assigned to one of at least a first layer and a second layer, where each of the first and second layers are associated with a same frequency band. The mobile users are further assigned, in the first layer, to different frequency sub-bands in the frequency band such that the users in the first layer have non-overlapping first sub-band assignments. The mobile users are further assigned, in the second layer, to different frequency sub-bands in the frequency band such that the users in the second layer have non-overlapping second sub-band assignments. The mobile users are then scheduled for transmission based on the first and second layer and the first and second sub-band assignments. In a further example decoding method, layer transmissions are decoded in succession with interference cancellation performed between each layer decoding step. In a second example decoding method, mobile users in multiple layers and within assigned channels are jointly decoded.
