Abstract:
An access point of a wireless communication network forms beams by applying a weightset for a beamforming weights matrix to signal streams. The Equivalent Isotropic Radiated Power (EIRP) that is emitted from an array of antenna elements at the access point is controlled by calibrating the transmission phase and gain of a respective transmit chain for each antenna element, providing a polar radiation model for an antenna element of the array, and determining a weightset for the weighting matrix subject to a constraint that a maximum total EIRP for the beams in combination in any azimuth direction is maintained within a predetermined EIRP limit, based at least on a spatial separation of the antenna elements, the polar radiation model and the calibrated transmission phase and gain of each respective transmit chain.

Claim (Index 1):
A method of controlling the Equivalent Isotropic Radiated Power (EIRP) emitted from an array of antenna elements at an access point of a wireless communication network, the access point being configured to form one or more beams by applying a respective weightset for a first and second mode of operation for a beamforming weights matrix to one or more signal streams, the method comprising:\n calibrating transmission phase and gain of a respective transmit chain for each antenna element; \n providing a polar radiation model for an antenna element of the array; \n determining a first weightset for the weighting matrix for a first mode of operation subject to a constraint that a maximum total EIRP for the one or more beams in combination in any azimuth direction is maintained within a predetermined EIRP limit; and \n switching from the first mode of operation to the second mode of operation, \n wherein the first mode is a sector mode in which signals from the respective transceiver chains are combined to form a beam sufficiently broad to provide coverage of a sector of a cellular radio network, and \n the second mode is a mode in which signals from the respective transceiver chains are combined to form at least one beam which is narrower in azimuth than that formed in the sector mode, the at least one beam being steered to an individual subscriber mode within the sector of a cellular radio network; and \n in the second mode of operation, configuring one or more beams by applying a second weightset for the beamforming weights matrix to the one or more signal streams, \n wherein the second weightset is determined subject to a constraint that a maximum total EIRP for the one or more beams in combination in any azimuth direction is maintained within the same predetermined EIRP limit as for the first mode, \n wherein said determining, in each mode of operation, is based at least on a spatial separation of the antenna elements, the polar radiation model and the calibrated transmission phase and gain of each respective transmit chain.
