1. A method in an access point for downlink transmission in a beamforming radio communication network, the method comprising:
- determining a priority for each of a plurality of terminal devices;
grouping the plurality of terminal devices to be scheduled for the downlink transmission into one or more groups, wherein the grouping comprises grouping the plurality of terminal devices in a descending order of the priority, and wherein the grouping the plurality of terminal devices in the descending order of the priority comprises;
(a) selecting terminal devices with the highest priority among the plurality of terminal devices,(b) if one of the selected terminal devices is covered by a beam of an existing group, grouping the selected terminal device into the existing group,(c) grouping remaining terminal devices of the selected terminal devices into one or more new groups at least based on positions of the remaining terminal devices with respect to the AP and respective channel qualities between the remaining terminal devices and the AP such that all terminal devices within a same group are covered by a beam, and(d) repeating steps (a)-(c) until the plurality of terminal devices are grouped; and
associating each of the one or more groups with a different one of digital chains in the AP, wherein payloads to be transmitted to terminal devices in a same group are processed by a digital chain associated with the group.
