Abstract
Techniques are described for precoded rate-splitting with multiple set-wise common messages for aggressive frequency reuse in a multi-beam satellites with co-channel interference. The satellite transmits private streams (PSs) to N user locations via spot beams. Embodiments identify K disjoint sets of the user locations (user groups) as being in adjacent spot beam coverage areas and having high channel vector collinearity. For each user group, data from the corresponding PSs is multiplexed to a respective set-wise common stream (SCS). PS precoders are each computed based on an associated target user location, and SCS precoders are each computed based on an associated target user group. The satellite allocates transmit power and transmits the N PSs and the K SCSs according to the PS beam weight vectors and the SCS beam weight vectors.
