Patent number: 11588599Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.Type: GrantFiled: April 27, 2021Date of Patent: February 21, 2023Assignee: Apple Inc.Inventors: Jeongho Jeon, Seau Lim, Yongjun Kwak, Anthony Lee, Hwan-Joon Kwon, Joonyoung Cho, Huaning Niu

Patent number: 11184930Abstract: A Narrowband-Internet-of-Things (NB-IoT) device may select between multiple carrier resources (of an anchor carrier and/or non-anchor carriers) to perform a Narrowband Physical Random Access Channel (NPRACH) procedure. The NB-IoT device may determine, based on a reference signal from an enhanced NodeB (eNB), a coverage level for the NB-IoT device and receive carrier configuration information, from the eNB, that indicates the carriers (e.g., an anchor carrier and one or more non-anchor carriers) that are available for NPRACH procedure. The NB-IoT device may select a carrier resource from among the carriers based on factors, such as the coverage level of the NB-IoT device and the Reference Signals Received Power (RSRP) thresholds and Repetition levels of the carrier resources. The NB-IoT device may use the selected carrier resource to initiate the NPRACH procedure.Type: GrantFiled: August 1, 2017Date of Patent: November 23, 2021Assignee: Apple Inc.Inventors: Seau Lim, Marta Martinez Tarradell, Debdeep Chatterjee, Youn Hyoung Heo

Publication number: 20210297867Abstract: Measurement configuration techniques for wideband coverage enhancement (WCE)-capable devices are described. According to various such techniques, a WCE-capable UE may be configured to recognize and apply distinct respective discovery signal measurement timing configurations (DMTCs) for WCE discovery reference signal (DRS) measurements and non-WCE DRS measurements. In some embodiments, the DMTC for WCE DRS measurements may specify a longer measurement periodicity for WCE DRS measurements than that applicable to non-WCE DRS measurements. In some embodiments, the DMTC for WCE DRS measurements may specify a larger measurement window for WCE DRS measurements than that applicable to non-WCE DRS measurements. In some embodiments, the WCE-capable UE may be configured to recognize and distinct respective measurement gap configurations for WCE and non-WCE measurements. Other embodiments are described and claimed.Type: ApplicationFiled: May 10, 2018Publication date: September 23, 2021Applicant: INTEL IP CORPORATIONInventors: Huaning NIU, Seau LIM, Anthony LEE, Candy YIU, Youn Hyoung HEO

Publication number: 20070248088Abstract: A method is provided of transmitting a multicast message in some of a set of cells of a network. The method comprises the steps of: (a) determining a first subset of cells in each of which resides at least one mobile terminal that subscribes to the multicast message service and is in an active state; (b) from the cells not in the first subset determining a second subset of cells in each of which resides at least one mobile terminal that subscribes to the multicast message service and is in an inactive state by the steps of: (i) in a cell sending an enquiry message as to whether there is/are mobile terminal(s) subscribing to the multicast message service and in an inactive state, (ii) receiving a reply from at least one such mobile terminal subscribing to the multicast message service and in an inactive state; (c) transmitting the multicast message in the first subset of the cells; and (d) transmitting the multicast message in the second subset of the cells.Type: ApplicationFiled: April 21, 2006Publication date: October 25, 2007Inventor: Seau Lim

Publication number: 20060234638Abstract: The present invention provides a method and an apparatus for responding to changes in measurement of a system load in a spread spectrum communication system. Using a load control algorithm, for example, the spread spectrum communication system may handle sudden changes or variations, such as spikes or steps in system load measurements for an uplink and/or a downlink between a mobile unit and an access network. The load control algorithm determines whether a sudden variation of a measured system load is generated by a source not under a power control or is caused by a variation of a spread spectrum communication system load. A load control measure may be selectively applied to adjust one or more parameters associated with the system load.Type: ApplicationFiled: April 19, 2005Publication date: October 19, 2006Inventors: Jens Mueckenheim, Philip Sapiano, Seau Lim
