Patent number: 12225494Abstract: Methods and apparatuses are described herein for multiple AP coordination in wireless local area networks (WLANs). For example, a station (STA) may receive, from a first access points (APs), a probe response frame that includes one or more indicators indicating multiple AP operation capabilities of the first AP and a second AP. The STA may transmit, to at least one of the first AP or the second AP, a multiple AP association request frame that enables the first AP to be associated with the second AP for a multiple AP operation. The STA may receive, from the first AP, a first multiple AP association response frame indicating acceptance or rejection of the multiple AP operation with the first AP. The STA may receive, from the second AP, a second multiple AP association response frame indicating acceptance or rejection of the multiple AP operation with the second AP.Type: GrantFiled: June 19, 2023Date of Patent: February 11, 2025Assignee: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Oghenekome Oteri, Alphan Sahin, Xiaofei Wang, Hanqing Lou, Li-Hsiang Sun, Rui Yang, Frank La Sita

Patent number: 12224859Abstract: Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.Type: GrantFiled: October 6, 2023Date of Patent: February 11, 2025Assignee: InterDigital Patent Holdings, Inc.Inventors: Liangping Ma, Shahrokh Nayeb Nazar, Oghenekome Oteri, Seyed Mohsen Hosseinian, Mahmoud Taherzadeh Boroujeni, Frank La Sita

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.
