Publication number: 20240146489Abstract: Carrier aggregation allows concurrent transmission on multiple component carriers (CC) to increase the data rate. A user equipment (UE) device in a cellular network provides periodic or aperiodic channel state information of the DL channel to a base station (eNB) for each of the aggregated CCs. The UE receives two or more reference signals corresponding to two or more aggregated CCs from an eNB. The UE computes a plurality of channel state information (CSI) reports for each of two or more aggregated CCs derived from the two or more reference signals. The UE receives a positive CSI request from the eNB for a CSI report and transmits CSI feedback to the eNB comprising one or more CSI reports selected from the plurality of CSI reports.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Inventors: Anthony Edet Ekpenyong, Runhua Chen, Eko Nugroho Onggosanusi

Patent number: 10462810Abstract: Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.Type: GrantFiled: October 27, 2017Date of Patent: October 29, 2019Assignee: Intel CorporationInventors: Aris Papasakellariou, Timothy M.
