  • ENHANCED MACHINE TYPE COMMUNICATIONS (MTC) FOR NON-TERRESTRIAL NETWORKS (NTN)
    Publication number: 20240057002
    Abstract: Apparatus and methods are provided to enhance communications for NTN. In some aspects, a base station (BS) comprises a processor configured to schedule an uplink transmission in response to an uplink transmission request from a user equipment (UE) using one or more subframes ranging from a first uplink subframe to a last uplink subframe. The processor is further configured to determine or receive a timing advance (TA) indicating amount of subframes transmitted during a time delay between the UE and the BS and schedule a downlink transmission aligned with the uplink transmission. The downlink transmission is blocked from subframes ranging from TA plus one or more subframes ahead of the first uplink subframe to TA minus one or more subframes ahead of the last uplink subframe. The processor is further configured to transmit and receive, via a non-terrestrial equipment, the uplink and the downlink.

  • PDSCH PROCESSING TIME CONSIDERATION FOR MULTI-CELL PDSCH SCHEDULING WITH A SINGLE DCI
    Publication number: 20240057085
    Abstract: Described are processing time approaches to simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In various approaches, simultaneously scheduling a plurality of physical downlink shared channels (PDSCHs) through a single DCI transmitted via a physical downlink control channel (PDCCH) occurs, wherein each of the plurality of PDSCHs is associated with a respective cell in a plurality of cells. The approaches further include transmitting data to or receiving data to a user equipment (UE) based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH.

  • SYSTEMS, METHODS, AND APPARATUSES FOR QUASI-CO-LOCATION (QCL) AND SPATIAL RELATION ASSUMPTIONS DURING RANDOM ACCESS PROCEDURES
    Publication number: 20240057166
    Abstract: Techniques described herein involve the use of quasi-co-location (QCL) capabilities and spatial relation assumption to enable a UE to designate a single beam for connections with a base station during a physical random access channel (PRACH) procedure. Once the PRACH procedure is complete, the beam may be reset after a pre-determined duration, which may account for decoding latency, or maintained until additional transmission configuration indication (TCI) is received. Also addressed are scenarios involving multiple transmission reception points (TRPs) and switching between beam management schemes based on one or more factors including device capabilities.

    Abstract: A network-controlled repeater (NCR) may receive configuration information from a base station to configure one or more receive (Rx) beams and corresponding time-domain resources for potential reception from one or more user equipments (UEs). The NCR may monitor for reception of a physical uplink channel or signal from the one or more UEs on the configured one or more Rx beams on the corresponding time-domain resources and determine that the physical uplink channel or signal is not received for at least a threshold amount of time. Additionally, the NCR may determine to refrain from at least one of additional monitoring for reception of the physical uplink channel or signal from the one or more UEs or transmission of one or more synchronization signal block (SSBs) to the one or more UEs for a duration of time.
