Patent number: 12316459Abstract: A communication system is disclosed in which a user equipment (UE) receives data associated with an Ultra-Reliable and Low-Latency Communications (URLLC) service and data associated with an Enhanced Mobile Broadband (eMBB) service. The UE generates a first Hybrid Automatic Repeat Request (HARQ) codebook for URLLC service and a second HARQ codebook for the eMBB service, bundles the first HARQ codebook into a single bit, and appends it to the end of the second HARQ codebook to form a multiplexed HARQ codebook. The UE then transmits the multiplexed HARQ codebook to the access network node.Type: GrantFiled: October 14, 2021Date of Patent: May 27, 2025Assignee: NEC CORPORATIONInventors: Ayesha Ijaz, Takahiro Sasaki

Publication number: 20240349145Abstract: A communication system comprising a non-terrestrial network part is disclosed in which a user equipment (UE) is served by one of the cells of the non-terrestrial network part. The UE determines whether to delay/suspend a small data transmission, based one or more associated parameters, so as to avoid a radio link failure or a handover. When the transmission is delayed/suspended, the UE initiates/resumes the data transmission in a new serving cell (e.g. after cell reselection or RRC establishment in the new cell), or via a relay (e.g. a device-to-device relay).Type: ApplicationFiled: June 30, 2022Publication date: October 17, 2024Applicant: NEC CorporationInventors: Yuhua CHEN, Neeraj GUPTA, Ayesha IJAZ

Publication number: 20240188057Abstract: A communication system is disclosed in which a base station communicates with user equipment via an associated cell having a system bandwidth. The system bandwidth comprises a bandwidth part having a set of contiguous physical resource blocks. The base station initiates a random access procedure with the user equipment; provides first information identifying a set of frequency resources for an uplink channel; and provides second information identifying at least one specific frequency resource, within said set of frequency resources, for said uplink communication. The first information is provided prior to completion of the random access procedure.Type: ApplicationFiled: January 17, 2024Publication date: June 6, 2024Applicant: NEC CorporationInventors: Ayesha IJAZ, Yassin Aden Awad, Robert Arnott

Publication number: 20240171320Abstract: A communication system is disclosed in which a user equipment (UE) communicates with a network node via a non-terrestrial network. The UE receives from the network node an indication that HARQ feedback is not required for a set of transmission occasions, and the UE omits HARQ feedback for that set of transmission occasions based on the information. The indication may be included in a DCI field or a MAC header.Type: ApplicationFiled: March 17, 2022Publication date: May 23, 2024Inventors: Ayesha IJAZ, Takahiro Sasaki
