1. A method for physical layer sub-cell identity allocation to select a sub-cell identity vector for a network device in a wireless network, the method comprising:
selecting a plurality of sub-cell identity vector candidates for the network device from a set of possible sub-cell identity vector candidates, wherein the network device has a plurality of sectors, each of which is to be allocated to one sub-cell identity within the sub-cell identity vector, and wherein the selecting removes one or more possible sub-cell identity vector candidates containing a same sub-cell identity for two or more adjacent sectors of the network device;
determining a plurality of conflict measurements for each of the plurality of sub-cell identity vector candidates, each conflict measurement for a metric measuring sub-cell identity confliction of the plurality of sectors with one or more neighbor cells of the network device in the wireless network, each of the one or more neighbor cells belonging to another network device;
deriving a single value from the plurality of conflict measurements for each of the plurality of sub-cell identity vector candidates; and
selecting the sub-cell identity vector for the network device from the plurality of sub-cell identity vector candidates based on the single value,
wherein the sub-cell identity defines an alignment of a reference signal within a slot.
