Abstract: A method in a communication system, in which multiple transmitters transmit respective control messages to a receiver over a control channel, includes allocating respective resources of the control channel to the control messages so as to cause a respective likelihood of interference between a control message and at least one other control message to be inversely related to a respective impact of the interference between the control message and the at least one other control message on an overall performance measure defined for the communication system, by allocating a dedicated resource to a first control message for which the interference has a high impact on the overall performance measure, and allocating a shared resource to a second control message for which the interference has a low impact on the overall performance measure. The control messages are transmitted from the transmitters over the control channel using the allocated resources.

Abstract: A method for signal processing in a receiver includes receiving in the receiver a Multi-User Multiple-Input Multiple-Output (MU-MIMO) signal. The MU-MIMO signal includes at least a first signal, which is precoded using a first precoding scheme and is addressed to the receiver, and a second signal, which is precoded using a second precoding scheme. An average error rate achievable in decoding the first signal in the presence of the second signal is computed. The average error rate is computed over a set of possible choices of the second precoding scheme. The first precoding scheme is selected from among a plurality of available precoding schemes so as to satisfy a criterion defined over the average error rate. The receiver sends feedback to a transmitter transmitting the first signal. The feedback depends on the selected first precoding scheme and causes the transmitter to control transmission of the first signal.

Abstract: A user device on a wireless network includes a receiver, a noise detector and a noise determiner. The receiver receives downlink data communications from a base station that indicates an allocation of time/frequency resource blocks at least to user devices that are communicating with the base station. The noise detector measures noise in a time/frequency resource block, comprising plural time/frequency bins, that is not allocated to one of the user devices. The noise determiner determines a level of interfering noise based on noise in the resource block that is not allocated to one of the user devices.
