Publication number: 20240155632Abstract: A communication apparatus has a receiver and a decoder. The receiver receives a control signal including first downlink control information and second downlink control information, and receives decoding area information that indicates whether the extended Physical Downlink Control Channel (PDCCH) should be decoded for each of a plurality of terminal apparatuses. The decoder decodes each of a plurality of first mapping candidates in the PDCCH area or decodes each of the plurality of first mapping candidates in the PDCCH area and each of the plurality of second mapping candidates in the extended PDCCH. A number of the second mapping candidates included in the user-specific search space equals to or is more than a number of the first mapping candidates included in the common search space.Type: ApplicationFiled: January 18, 2024Publication date: May 9, 2024Inventors: Yoshiko SAITO, Ayako HORIUCHI, Seigo NAKAO, Akihiko NISHIO, Daichi IMAMURA, Alexander GOLITSCHEK EDLER VON ELBWART, Sujuan FENG

Publication number: 20240080760Abstract: Disclosed is a wireless communication base station device capable of reducing the power consumption of a terminal when broadband transmission is performed with only an uplink. With this device, a setting unit sets mutually different terminal IDs per a plurality of uplink unit bands for a terminal that communicates using a plurality of uplink unit bands and prescribed downlink unit bands which are fewer in number than the uplink unit bands; a control unit that respectively allocates resource allocation information per a plurality of uplink unit bands to a PDCCH arranged in a prescribed downlink unit band; and a PDCCH creation unit that creates a PDCCH signal by respectively masking the resource allocation information per a plurality of uplink unit bands with the terminal ID that has been set per a plurality of uplink unit bands.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Inventors: Akihiko NISHIO, Seigo NAKAO, Yoshiko SAITO, Alexander GOLITSCHEK EDLER VON ELBWART
