Patent number: 11134432Abstract: An apparatus of a user equipment (UE) includes processing circuitry configured to decode a master information block (MIB) using a set of physical broadcast channel (PBCH) symbols received within a downlink frame to obtain system frame number (SFN) information. The downlink frame includes multiple copies of the PBCH symbols within at least three subframes of the downlink frame. A system information block (SIB) may be decoded based on the SFN information, to obtain uplink channel configuration information. Random access channel (RACH) procedure may be performed with a base station (BS) based on the uplink channel configuration information, to obtain an uplink resource assignment. A connection setup completion message can be encoded for transmission to the BS using the uplink resource assignment. The set of PBCH symbols can include a set of four legacy PBCH symbols.Type: GrantFiled: February 2, 2018Date of Patent: September 28, 2021Assignee: Apple Inc.Inventors: Anatoliy Ioffe, Debdeep Chatterjee, Marta Martinez Tarradell, Andrey Chervyakov, Jie Cui, Seau S.

Patent number: 11102733Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for delivering UE capability indication to a positioning server in a wireless communication network. A user equipment (UE) or evolved NodeB (eNB) may process and assign narrowband physical uplink shared channel (NPUSCH) resources based on a comparison between a measured narrowband reference signal received power (NRSRP) in a narrowband physical random access channel (NPRACH) transmission and at least one threshold value. Embodiments describe how to configure the NPUSCH transmission utilizing NPRACH procedure at very low receiving Signal-to Noise ratio (SNR) to alleviate negative impacts caused by less accurate NRSRP measurements and/or increased absolute power tolerance at very low receiving SNR scenarios. Other embodiments may be described and claimed.Type: GrantFiled: May 3, 2018Date of Patent: August 24, 2021Assignee: Apple Inc.Inventor: Anatoliy Ioffe

Publication number: 20200128618Abstract: Embodiments include apparatuses, methods, and systems that may decode system information by a UE in a wireless network to communicate with an eNB or a gNB. The apparatus may include a memory and processing circuitry coupled with the memory. The processing circuitry may identify a remaining time period of a current moment in a current time window, identify a decoding time interval for decoding system information based on a channel condition for a channel between the UE and the eNB or the gNB. Based on a first relationship between the decoding time interval and the remaining time period, the processing circuitry may store, or cause to store, in the memory one or more copies of the system information received during the decoding time interval; and may further decode, or cause to decode, the one or more copies of the system information.

Publication number: 20170142688Abstract: In a wireless network, a user equipment (UE) can communicate with an Evolved Node B (eNodeB). During at least some times, the UE transmits a data stream to the eNodeB, over one of several available antenna states on the UE. The antenna states can include one or more tuning states for each antenna port on the UE. At predetermined times, which can be periodic, the UE ceases transmission of the data stream, transmits a test signal sequentially over each of its antenna states, receives a signal back from the eNodeB indicating which of the antenna states provides the strongest signal, and switches to the indicated antenna state. After switching, the UE can resume transmission of the data stream over the indicated antenna state. In some examples, the UE can repeat the antenna tuning/retuning process periodically.Type: ApplicationFiled: January 31, 2017Publication date: May 18, 2017Inventors: Anatoliy Ioffe, Boyan Yanakiev, Thomas J.
