Abstract: There is provided a communication method for a coordinator communication device, including generating a first scheduling element to be used by a first communication device and a second scheduling element to be used by a second communication device; and transmitting the first and second scheduling elements to the first and second communication devices. The second scheduling element includes a second allocation indicating a time-frequency resource allocated to the second communication device. The first scheduling element includes a first allocation indicating a time-frequency resource allocated to the first communication device and optionally includes a first virtual allocation that is a duplicate of the second allocation. The first communication device performs communication in accordance with a first communication system using a first frequency band, and the second communication device performs communication in accordance with the first communication system or a second communication system using a second frequency band that includes the first frequency band.

Abstract: A method for performing spatial sharing between an existing SP and a candidate SP includes transmitting a first measurement request to an STA involved in the candidate SP carrying measurement configuration information for measurement over primary tier 1 channel of a tier 2 channel. The measurement configuration information includes the method that is to be used for the requested measurement, the measurement start time, the measurement duration, the number of time blocks within the measurement duration, the number of concurrent measurements to be performed using plural RX antenna configurations, and the method for reporting results of plural concurrent measurements, wherein the duration of each time block is the same.
