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.

Abstract: In the static and exclusive spectrum allocation paradigm, the spectrum-access parameters for a service are chosen to mitigate potential harmful-interference and ensure minimum performance under worst-case conditions. The new dynamic spectrum-sharing paradigm necessitates dynamically defining and enforcing the spectrum-access rights while accommodating the dynamics of the RF environment and the spectrum-access scenarios. To enforce spectrum-access rights, emphasis is placed on capturing the use of spectrum by an individual transceiver. Spectrum-access rights are articulated in terms of the characterization of the spectrum used by an individual transceiver in the space, time, and frequency dimensions. In order to estimate the use of spectrum in real time, an RF-sensor network is employed, the network uses interference-tolerant algorithms to estimate the transceiver spectrum-access parameters and to characterize the propagation environment.
