After detecting a clear channel assessment (CCA), a transmitter selects a configuration of a CUBS associated with the transmitter based on the CCA opportunity assigned to the network. The configuration of the CUBS associated with the transmitter may include a set of frequency subcarriers for CUBS transmissions. The transmitter transmits the CUBS according to transmission characteristics based on the CCA opportunity. In additional aspects, randomization may be introduced into the frequency subcarrier allocations of CUBS configurations where the transmitter receives assignment of virtual frequency subcarriers for CUBS transmissions and maps the virtual subcarrier to physical frequency subcarriers for CUBS transmission. Additional aspects allow for pattern offset values to be determined independently from the transmitter cell identifier. In such aspects, the assigned pattern offsets may be cell identifier-independent, while others may be cell identifier-dependent."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel usage beacon signal design for cooperative communication systems","description":"Design of channel usage beacon signals (CUBS) in cooperative networks is disclosed.
