Patent number: 11917468Abstract: A communication system is disclosed which a base station configures a user equipment (UE) to carry out measurements of signals transmitted in a plurality of neighbour cells and to transmit a measurement report. The UE performs the signal measurements and transmits the measurement report, which comprises the measurement results for at least one neighbour cell and further includes, for at least one reported neighbour cell, an associated unique cell identifier together with the corresponding measurement. The base station identifies a corresponding neighbour cell, from among a plurality of neighbour cells, based on the reported unique cell identifier, and triggers a communication procedure involving the UE and that neighbour cell.Type: GrantFiled: December 28, 2018Date of Patent: February 27, 2024Assignee: NEC CORPORATIONInventors: Yuhua Chen, Neeraj Gupta, Jagdeep Ahluwalia Singh, Robert Arnott

Patent number: 11917600Abstract: 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: GrantFiled: March 30, 2022Date of Patent: February 27, 2024Assignee: NEC CORPORATIONInventors: Ayesha Ijaz, Yassin Aden Awad, Robert Arnott

Patent number: 11909676Abstract: A communication system is disclosed in which an NR radio access network (RAN) node identifies resources, that the NR RAN node is to use for transmissions, for protection from interference from another RAN node. The NR RAN node sends, to the other RAN node, information indicating the identified resources for protection from interference. The information indicating the identified resources comprises a list of parameters, typically including resource bitmaps, based on which the other RAN node is able to determine the resources for protection from interference.Type: GrantFiled: September 21, 2022Date of Patent: February 20, 2024Assignee: NEC CORPORATIONInventors: Chadi Khirallah, Yassin Aden Awad, Sadafuku Hayashi, Tao Guo, Robert Arnott

Publication number: 20230403571Abstract: A communication system is disclosed in which a base station serves a communication area, wherein the communication area is formed by a plurality of directional beams each covering a respective portion of the communication area and each having a different respective beam identifier. The base station communicates control information, for a communication device (UE), using at least one directional beam associated with that communication device (e.g., a UE-specific operational beam set).Type: ApplicationFiled: August 29, 2023Publication date: December 14, 2023Applicant: NEC CORPORATIONInventors: Chadi KHIRALLAH, Yassin Aden AWAD, Neeraj GUPTA, Robert ARNOTT

Patent number: 11831397Abstract: Scrambling code is initialized based on a parameter, n?RNTI, that changes from a given block of sub-frames to a subsequent block of sub-frames wherein the parameter is derived using one of the following formulas: n?RNTI=(nRNTI+SFN)mod 216 n?RNTI=(nRNTI+k)mod 216 where nRNTI is a temporary identifier associated with a mobile device connected to said cell and for which said scrambling code is applicable; and SFN is a system frame number associated with said at least one of said sequence of sub-frames; and k is a sub-frame counter.Type: GrantFiled: October 15, 2021Date of Patent: November 28, 2023Assignee: NEC CORPORATIONInventors: Robert Arnott, Yassin Aden Awad, Caroline Liang

Publication number: 20230363002Abstract: A method is disclosed in which a user equipment (UE) that communicates with a radio access network (RAN) maintains information for configuring timing of fixed frame period (FFPs) for a listen-before-talk (LBT) procedure. When the UE has data to be transmitted, it performs a clear channel assessment, CCA, to determine if a communication channel is clear. When the CCA indicates that the communication channel is clear a channel occupancy time, COT, is initiated for the UE within a subsequent FFP and transmission of the data commences. However, transmission of the data ceases following receipt of an indication, from a node of the RAN, that the transmission should be stopped.Type: ApplicationFiled: October 14, 2021Publication date: November 9, 2023Applicant: NEC CorporationInventors: Caroline LIANG, Robert ARNOTT, Takahiro SASAKI

Publication number: 20230269058Abstract: A method of signaling resource allocation data in a communication system which uses a plurality of sub-carriers arranged in a sequence of chunks. An allocation of the sub-carriers for each of a plurality of user devices is received. The received allocations are processed to determine, for each user device, data identifying a start chunk and an end chunk within the sequence of chunks, which depend upon the sub-carriers allocated to the user device. Different resource allocation data is generated for each of the user devices using a predetermined mapping which relates the data identifying the corresponding start chunk and end chunk determined by the processing step to resource allocation data comprising a unique value. The respective resource allocation data is signaled to each of the plurality of user devices.Type: ApplicationFiled: April 26, 2023Publication date: August 24, 2023Applicant: NEC CorporationInventors: Robert ARNOTT, Diptendu Mitra
