Patent number: 12237928Abstract: A WTRU may select sidelink unicast or groupcast to transmit data. If the WTRU selects sidelink unicast, the WTRU may select to use HARQ ACK/NACK feedback for the transmission. If the WTRU selects sidelink groupcast, either HARQ NACK or HARQ ACK/NACK may be selected depending upon one or more factors. 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: GrantFiled: January 16, 2024Date of Patent: February 25, 2025Assignee: InterDigital Patent Holdings, Inc.Inventors: Chunxuan Ye, Fengjun Xi, Kyle Jung-Lin Pan

Patent number: 12231279Abstract: Methods and an apparatus for performing synchronization in New Radio (NR) systems are disclosed. A frequency band may be determined and may correspond to a WTRU. On a condition that the operational frequency band is a lower frequency, a synchronization signal block (SSB) index may be implicitly. On a condition that the operational frequency band is a higher frequency, an SSB index may be determined based on a hybrid method which includes determining the SSB index using both an implicit and an explicit method. A configuration of actually transmitted SSBs may be determined using a multi-level two stage compressed indication where SSB groups are determined based on a coarse indicator and actually transmitted SSBs with the SSB groups are determined based on a fine indicator.Type: GrantFiled: February 27, 2024Date of Patent: February 18, 2025Assignee: SONY GROUP CORPORATIONInventors: Kyle Jung-Lin Pan, Fengjun Xi, Janet A.

Publication number: 20250038829Abstract: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beamin the beam group.Type: ApplicationFiled: October 16, 2024Publication date: January 30, 2025Inventors: Kyle Jung-Lin Pan, Fengjun Xi, Afshin Haghighat, Oghenekome Oteri, Chunxuan Ye, Frank La Sita, Robert L.

Publication number: 20250031171Abstract: A wireless transmit/receive unit (WTRU) may send to a network node a registration request message requesting to register with the network and indicating that the WTRU is capable of preserving, when the WTRU becomes unavailable to the network, context information associated with the communications between the WTRU and the network. The network node may indicate in a registration accept message that the network supports the preservation of context information when the WTRU becomes unavailable to the network. Based on a determination that the WTRU will become unavailable to the network, the WTRU may send to the network a message indicating a request to preserve the context information.

Patent number: 12207233Abstract: Methods, devices, and systems for resource allocation are disclosed herein. Specifically, a wireless transmit receive unit (WTRU) may measure a reference signal received power (RSRP) level and a received signal strength indicator (RSSI) value of one or more resources in each of a plurality of patterns. The WTRU may exclude, from the selection, each pattern for which at least one resource in the pattern is reserved by another WTRU and has an RSRP greater than a threshold. On a condition that at least one of the plurality of patterns is not excluded, the WTRU may select a pattern with a lowest pattern RSSI value and a one or more resources satisfying a quality of service (QoS) requirement of data of the WTRU. The WTRU may then transmit the data of the WTRU using the selected pattern.Type: GrantFiled: January 9, 2020Date of Patent: January 21, 2025Assignee: InterDigital Patent Holdings, Inc.Inventors: Chunxuan Ye, Fengjun Xi, Hanqing Lou, Kyle Jung-Lin Pan
