The base station also includes a receive path circuitry to receive ACK/NACK modulation in response to the data streams. If the subscriber station is configured to transmit ACK/NACK using one uplink transmit antenna port and channel selection with PUCCH format 1B, a modulation symbol is transmitted on one (PUCCH) i determined based at least partly upon a channel selection mapping table. If the subscriber station is configured to transmit ACK/NACK using two uplink transmit antenna ports and channel selection with PUCCH format 1B, the ACK/NACK modulation symbol is transmitted on two PUCCHs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for uplink acknowledgement signaling in carrier-aggregated wireless communication systems","description":"A base station includes a transmit path circuitry to transmit DL grant, data streams, and a control signal to configure a number of uplink transmit antenna ports PUCCH to a subscriber station.
