Patent number: 11950242Abstract: This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit an announcement information block (MB) in a downlink shared data channel (e.g., PDSCH), wherein the AIB contains information useable by a UE in determining the location of system information in the downlink shared data channel. The UE can thus determine the location of and decode system information without having to decode a downlink control channel (e.g., PDCCH). This may be important for certain classes of devices, such as link budget limited devices, which have issues in decoding the downlink control channel. Improved paging scheduling techniques are also disclosed which more efficiently use PDCCH paging resources.Type: GrantFiled: December 12, 2019Date of Patent: April 2, 2024Assignee: Apple Inc.Inventors: Tarik Tabet, Awais M. Hussain, Syed Aon Mujtaba, Moustafa M. Elsayed

Patent number: 11737118Abstract: This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit a master information block (MIB), a first system information block (SIB), and second SIBs. The first SIB and the second SIBs may be configured for different device categories, and may accordingly have different characteristics. For example, the first SIB may be configured for link budget limited devices, and may include information specific to such devices and/or may exclude information not relevant to such devices or not critical to accessing the cell. In some instances, the first SIB may also include information from the MIB, such that at least some devices may be able to decode the first SIB and gain cell access without decoding the MIB.Type: GrantFiled: July 1, 2022Date of Patent: August 22, 2023Assignee: Apple Inc.Inventors: Tarik Tabet, Farouk Belghoul, Awais M.

Patent number: 11375420Abstract: This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.Type: GrantFiled: August 12, 2020Date of Patent: June 28, 2022Assignee: Apple Inc.Inventors: Tarik Tabet, Farouk Belghoul, Samy Khay-Ibbat, Sarma V.

Publication number: 20220190954Abstract: A user equipment device (UE) may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and additional optimization requirements. The UE may use physical channels and procedures (e.g. it may receive and decode control channels) in a manner compatible with and not infringing on the operation of other UEs operating in the same network, while allowing the network more flexibility to assign resources. Specifically, resources for EPDCCH on UE-specific SS and EPDCCH on common SS may be shared. That is, the resources for two search spaces may be overlaid partially or in full, giving the network more flexibility in allocating resources. Furthermore the DCI formats for MPDCCH may be extended to devices operating according to the new device category, which enables the coverage enhancement of MTC for these devices.Type: ApplicationFiled: March 3, 2022Publication date: June 16, 2022Inventors: Awais M.

Patent number: 11122565Abstract: This disclosure relates to performing cellular communication in unlicensed spectrum using a flexible slot structure. A cellular base station may perform a listen-before-talk procedure, and may transmit a reservation frame when the listen-before-talk procedure is successful. The reservation frame may reserve a wireless medium for a transmit opportunity. Transmission slots may be scheduled for communication with one or more wireless devices during the transmit opportunity. The transmission slots may be selected from multiple possible uplink transmission slot types and multiple possible downlink transmission slot types. Indications of the scheduled transmission slots, including indications of slot types of the scheduled transmission slots, may be provided to the wireless devices. Wireless communication may be performed between the cellular base station and the wireless devices according to the scheduled transmission slots.Type: GrantFiled: December 12, 2019Date of Patent: September 14, 2021Assignee: Apple Inc.Inventors: Farouk Belghoul, Christian W.
