Abstract: Various embodiments disclosed herein provide for reduced overhead signaling when a user equipment device is being configured with multiple bandwidth parts for downlink transmission. When a user equipment device is being configured with multiple bandwidth parts (channels on an aggregate carrier), the signaling that indicates the codebook subset restriction bit map, rank restriction bit map, and beam restriction bit map needs to be repeated for each bandwidth part. Often however, the restriction bit maps are repeated in the bandwidth parts, and so overhead can be reduced by encoding a confirmation bit in each bandwidth part, such that if the confirmation bit is set to “1”, the user equipment device can know to apply the restriction bit map from the primary bandwidth part to the secondary bandwidth part, without having to encode the secondary bandwidth part restriction bit map.
