Title: PROCESSING DEVICE, TRANSMITTING DEVICE AND METHODS THEREOF
Abstract:
A processing device (100) for a wireless communication system, the processing device (100) being configured to: obtain a first downlink precoder (VDL1) for a set of transmit antenna elements (302a, 302b,..., 302z) associated with a set of receiving devices (600a, 600b,..., 600z); obtain a first downlink transmit power allocation (PDL1) for a total transmit power allocated to the set of receiving devices (600a, 600b,..., 600z); if a fraction of the total transmit power allocated to the set of receiving devices (600a, 600b,..., 600z) remains after having obtained the first downlink transmit power allocation (PDL1): compute at least one second downlink precoder (VDL2) for the set of transmit antenna elements (302a, 302b,..., 302z) based on a power allocation for the remaining fraction of the total transmit power allocated to the set of receiving devices (600a, 600b,..., 600z); compute at least one second downlink transmit power allocation (PDL2) for the remaining fraction of the total transmit power allocated to the set of receiving devices (600a, 600b,..., 600z) based on the second downlink precoder (VDL2 ); compute a resultant downlink precoder and power allocation comprising a first product of the first downlink precoder (VDL1) and the first downlink transmit power allocation (PDL1), and a second product of the second downlink precoder (VDL2) and the second downlink transmit power allocation (pDL2)- Furthermore, the invention also relates to a transmitting device, a corresponding method, and a computer program.
