Publication number: 20250030512Abstract: Systems and methods for configured grant for multi-panel Uplink (UL) transmission are provided. In some embodiments, a method performed by a User Equipment (UE) for transmitting PUSCH configured grant to multiple-TRPs includes: receiving a configuration of at least one unified TCI state, indicating mTRP operation; receiving an indication of a configured grant, indicating either mTRP operation using repetition or Simultaneous Transmission Across Multiple Panels (STxMP); and transmitting a PUSCH according to the configuration o. In this way, the unified TCI state framework can be extended to mTRP and multi-panel transmission for configured grant. With the unified TCI state framework, separate spatial relations do not have to be configured for UL transmission. Hence, unified TCI state framework can provide some higher layer overhead savings. By extending unified TCI state framework for mTRP and multi-panel transmission for configured grant, configured grant based PUSCH can also leverage this advantage.Type: ApplicationFiled: November 9, 2022Publication date: January 23, 2025Inventors: Siva Muruganathan, Andreas Nilsson, Shiwei Gao, Claes Tidestav

Patent number: 12192047Abstract: According to a first aspect of embodiments herein, the object is achieved by a method performed by a User Equipment (UE) for monitoring a beam transmitted by a base station in a radio communications network. The base station is serving the UE. The UE monitors a reference signal related to the beam, from the base station. Each time a quality of the reference signal is below a first threshold, the UE generates an Out-Of-Synchronization (OOS) event. When the number of OOS events reaches an OOS Beam Failure Detection (BFD) threshold, the UE triggers a beam recovery preparation procedure, and when the number of OOS events reaches an OOS Radio Link Monitoring (RLM), threshold, the UE starts an RLF timer.Type: GrantFiled: December 12, 2023Date of Patent: January 7, 2025Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Icaro L.

Patent number: 12191935Abstract: An access node transmits, in a downlink signal having a series of subframes, a beam-formed reference signal in subframes, where the beam-formed reference signals are transmitted in fewer than all of the subframes of the downlink signal. A first subset includes beam-formed reference signals corresponding to a first frequency or first localized range of frequencies, and a second subset includes beam-formed reference signals corresponding to a second frequency or second localized range of frequencies. The second frequency or second localized range of frequencies is spaced apart from and differing from the first frequency or first localized range of frequencies. A user equipment, UE, receives, in the downlink signal, the beam-formed reference signal in each of a plurality of subframes. The UE performs mobility management measurements using at least the first subset of the received beam-formed reference signals and performs RLM using the second subset of the received beam-formed reference signals.Type: GrantFiled: September 15, 2020Date of Patent: January 7, 2025Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Icaro L.
