Abstract
A method of mapping transmission stations in a wireless network by grouping the transmission stations such that each transmission station in the same group transmits a sounding signal in the same time symbol. A method of grouping transmission stations in a wireless network includes sorting the transmission stations in descending order according to a number of transmission links of each transmission station that are unmapped, evaluating each transmission station based on how many unmapped transmission links can be mapped if the evaluated transmission station is made to transmit a sounding signal, placing each transmission station into a group, based on the evaluation, until all of the transmission links are mapped or until the maximum number of sounding bands are used, and, if all of the transmission links are not mapped, repeating the sorting, evaluating, and placing for each time symbol until all of the transmission links are mapped.
