RESOURCE UTILIZATION FOR UPLINK TRANSMISSION BASED ON INDICATED INTERFERENCE

摘要

According to a disclosed example, an intention of a first wireless communication device to use a first power level and a first time-frequency resource for up-link transmission to a first cellular communication network is detected. At a second wireless communication device, a signal is received from the first device indicative of up-link transmission. The second device determines whether or not an interference (caused by the up-link transmission of the first device and affecting a down-link reception of the second device from a second cellular communication network at a second power level in a second time-frequency resource) has a third power level associated with the first power level that exceeds a power level threshold associated with the second power level. The second device transmits an interference indication to the first device using a third time-frequency resource if it is determined that the third power level exceeds the power level threshold, and the interference indication is received at the first device. The first device determines whether or not to use the first time-frequency resource for up-link transmission based on the interference indication. Corresponding computer program product, arrangements and wireless communication device are also disclosed.
