Publication number: 20240397453Abstract: Maintaining time alignment with multiple carriers is contemplated. A group of uplink carriers (UL CC sets) that operate with a single Timing Advance (TA) may be determined, and a TA value may be applied to a specific UL CC set. A wireless transmit/receive unit's (WTRU) capability of using multiple TAs may define a group index of a few bits for each UL CC set. A TA Command received in a Random Access Response message may be used to apply the TA value to each UL carrier of the UL CC set. The WTRU may determine which UL CC set the TA value applies to based on which DL carrier the command was transmitted from. The WTRU may determine which UL CC set the TA value applies to based on the Group Index being explicitly provided in the command. The WTRU may release multi-CC configurations upon Time Alignment Timer (TAT) expiry.Type: ApplicationFiled: August 1, 2024Publication date: November 28, 2024Applicant: InterDigital Patent Holdings, Inc.Inventors: Paul Marinier, Bhaskar M.

Publication number: 20240323874Abstract: An apparatus and method for synchronization between a WTRU and a gNB are disclosed. The WTRU may receive a multiple beam synchronization signal from the gNB during synchronization. For each beam received by the WTRU, of the multiple beam synchronization signal, the WTRU may compare a received energy of the beam against a first threshold. A multiple beam synchronization signal may include a first and second synchronization signal (SS). If one or more beams of the multiple beam synchronization signal meets or exceeds the first threshold, the WTRU may report an indication of pre-synchronization to the gNB. This pre-synchronization may indicate to the gNB that a WTRU exists in an area of a particular beam of the WTRU. In this way, a gNB may target the WTRU using transmissions directed towards the WTRU.Type: ApplicationFiled: June 3, 2024Publication date: September 26, 2024Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Kyle Jung-Lin Pan, Chunxuan Ye, Robert L.
