Pilot signal transmission sequences and methods for use in a multi-sector
cell. Pilots in different sectors are transmitted at different known
power levels. In adjacent sectors a pilot is transmitted while no pilot
is transmitted in the adjoining sector. This represents transmission of a
NULL pilot signal. A cell NULL is also supported in which NULL pilots are
transmitted in each sector of a cell at the same time. Multiple pilot
signal measurements are made. At least two channel quality indicator
values are generated from measurements corresponding to at least two
pilot signals of different power levels. The two values are transmitted
back to the base station which uses both values to determine the transmit
power required to achieve a desired SNR at the wireless terminal. The
wireless terminal also reports information indicating its location to a
sector boundary.
