Title: SYSTEM AND METHOD FOR MA SIGNATURE ASSIGNMENT BASED ON UE GROUP SEPARATION
Abstract:
In a wireless communication system, user equipments (UEs) may be partitioned into different groups, e.g. based on spatial separation. UEs may use multiple access (MA) signatures that have low or no correlation to each other if the UEs are in the same group. The MA signatures used by one group of UEs may be more correlated with the MA signatures used by another group of UEs. If the UEs are partitioned into the different groups based on spatial separation, then the spatial separation between the different groups may assist in increasing the reliability of detection if two UEs in different groups use correlated MA signatures.
