The WTRU may select HARQ NACK or HARQ ACK/NACK depending upon one or more of: a number of WTRUs to receive the data; a condition of a channel associated with transmission; or a quality of service associated with transmission. The WTRU may select a first or second PSFCH format for feedback based upon one or more factors. The WTRU may select a first or second PSFCH format based upon one or more of: the selected sidelink unicast or groupcast; the selected HARQ NACK or HARQ ACK/NACK feedback; or a quality of service associated with the transmission.Type: ApplicationFiled: January 9, 2020Publication date: March 17, 2022Applicant: IDAC Holdings, Inc.Inventors: Chunxuan Ye, Fengjun Xi, Kyle Jung-Lin Pan

Patent number: 11251908Abstract: Systems, methods, and instrumentalities are disclosed for advanced coding on retransmission of data and/control information. The systems methods, and instrumentalities may include one or more of the following: chase combining for retransmission; incremental redundancy (IR) hybrid automatic repeat request (IR-HARQ); or incremental freezing (IF) HARQ. IF-HARQ may use lower coding rates and/or increased mother codeword length.

Patent number: 11108500Abstract: Latency reduction by fast forward (FF) in multi-hop communication device and/or systems is disclosed. Packets may be received and forwarded using a codeword (CW)-based approach with and/or without per-CW CRC. A FF session may have a flow ID and packets may have sequence numbers.

Publication number: 20210267015Abstract: A method and apparatus for performing sidelink communications in a wireless transmit receive unit (WTRU) using Long Term Evolution (LTE) and New Radio (NR) technologies is described herein. A WTRU receives downlink control information (DCI) on a physical downlink control channel (PDCCH) from a gNodeB (gNB), wherein the DCI is associated with a cyclic redundancy check (CRC). The a determination is made as to whether the DCI is for an LTE or NR technology sidelink transmission. On a condition that the DCI is for NR technology, the WTRU determines which transmit modulation and coding scheme (MCS) table to apply based on the masking of at least some of the bits in the CRC. Then the WTRU transmits sidelink data on resources indicated by the DCI using the determined MCS table. The WTRU may also receive HARQ feedback on resources indicated by the DCI for HARQ feedback.Type: ApplicationFiled: May 10, 2021Publication date: August 26, 2021Applicant: IDAC HOLDINGS, INC.Inventors: Kyle Jung-Lin PAN, Fengjun XI, Chunxuan YE

Patent number: 11038540Abstract: 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: GrantFiled: January 31, 2018Date of Patent: June 15, 2021Assignee: IDAC HOLDINGS, INC.Inventors: Chunxuan Ye, Hanqing Lou, Fengjun Xi, Kyle Jung-Lin Pan
