Patent number: 12047309Abstract: Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and UE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.Type: GrantFiled: April 11, 2023Date of Patent: July 23, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Paul Marinier, Moon-il Lee, Afshin Haghighat, Shahrokh Nayeb Nazar, Guodong Zhang, Marian Rudolf

Publication number: 20240196409Abstract: Methods and apparatus for wireless transmit/receive unit (WTRU) power control are described. A method includes receiving a time domain resource allocation (TDRA) list configuration including entries, each including a resource allocation that includes a slot offset value. L1 signaling is received indicating a minimum slot offset value. Downlink control information (DCI) is decoded on a physical downlink control channel in a slot. An index is obtained from the decoded DCI, identifying an entry in the TDRA list. A particular slot offset value identified by the index is retrieved from the TDRA list and compared with the minimum slot offset value. If the particular slot offset value is less than the minimum slot offset value, the entry is invalid. If the particular slot offset value is greater than or equal to the minimum slot offset value, a physical downlink shared channel is received.Type: ApplicationFiled: November 30, 2023Publication date: June 13, 2024Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Moon-il Lee, Erdem Bala, Janet A.
