Patent number: 11855763Abstract: In NR networks with dynamic TDD operation, two types of cross-link interference (CLI) arise: UE-to-UE and TRP-to-TRP. UE-to-UE CLI measurement and reporting can assist the network in managing CLI. The problem is that, for a cell to be able to measure the CLI reference signal transmitted by UEs in another neighboring cell, the cell needs to know what CLI-RS transmission resources assigned to the UEs in the neighboring cells. Embodiments of the present disclosure provide systems and methods for the exchange of such information between cells. In some embodiments, for example, a gNB sends a request message to a neighboring gNB and the neighboring gNB sends back a response message that includes TDD DL/UL Configurations of its cells and a list of the resources assigned to its UEs for transmission of UE-to-UE CLI reference signal.Type: GrantFiled: January 10, 2020Date of Patent: December 26, 2023Assignee: Apple Inc.Inventors: Hassan Ghozlan, Dawei Ying, Qian Li, Geng Wu

Patent number: 11831480Abstract: Aspects of this disclosure relate receiving a reference symbol from at least one antenna. The reference symbol includes a portion of a first transmitted reference symbol and a portion of a second transmitted reference symbol. The first transmitted reference symbol includes a symbol and a cyclically shifted portion of the symbol having a cyclic shift length. The second transmitted reference symbol includes a cyclically shifted version of the first transmitted reference symbol that is cyclically shifted relative to the first transmitted reference symbol by the cyclic shift length. The reference symbol is processed. In certain embodiments, processing the reference symbol can account for (i) a frame offset between uplink symbols and downlink symbols and (ii) another timing offset between downlink transmission and uplink reception.Type: GrantFiled: October 18, 2021Date of Patent: November 28, 2023Assignee: XCOM Labs, Inc.Inventors: Jing Jiang, Anthony Edet Ekpenyong, Mark Vernon Lane, Michael J Roe, Liang Mei, Hassan Ghozlan, Tamer Adel Kadous

Patent number: 11664952Abstract: Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel.Type: GrantFiled: October 25, 2021Date of Patent: May 30, 2023Assignee: Apple Inc.Inventors: Joonbeom Kim, Vesh Raj Sharma Banjade, Guangjie Li, Qian Li, Satish Chandra Jha, Hassan Ghozlan, Dawei Ying, Yaser M.

Publication number: 20220123847Abstract: Apparatuses, methods, and computer-readable media are provided for determination of reference signal received power (RSRP) to estimate cross-link interference. The approach uses a received signal from a second UE and downlink (DL) timing information from a transmission reception point (TRP). The approach generates a corrected timing signal based on the received signal, the DL timing information and a reference sequence, and then extracts a symbol from the received signal and the corrected timing signal. The approach then transforms using a fast Fourier transform (FFT) circuit the symbol, and then cross-correlates with a reference sequence to generate a correlation result from which the RSRP is estimated.Type: ApplicationFiled: January 13, 2020Publication date: April 21, 2022Applicant: Apple Inc.Inventors: Hassan GHOZLAN, Qian LI, Dawei YING, Geng WU

Publication number: 20220116898Abstract: In a wireless communication environment, there may arise a timing misalignment for SRS-RSRP measurement. In order to address this issue, a UE may receive an uplink transmission from second UE containing the uplink transmission timing for the first UE. The UE may then set its measurement timing to be the same as the uplink transmission timing. The UE then carries out SRS-RSRP measurement according to the newly-set measurement timing.Type: ApplicationFiled: February 17, 2020Publication date: April 14, 2022Applicant: Apple Inc.Inventors: Dawei YING, Hassan GHOZLAN, Qian LI, Geng WU

Publication number: 20220116129Abstract: Some embodiments of this disclosure include apparatuses and methods for measuring and/or reporting UE-to-UE crosslink interference (CLI). In some embodiments, a communication network may use transmission reception points (TRPs) to facilitate communications for user equipment (UE). A first TRP may command a first UE to transmit a crosslink interference reference signal (CLI-RS) according to a particular time behavior. A second TRP may command a second UE to measure UE-to-UE CLI using the CLI-RS and the time behavior. The second UE may then report the measured CLI indicating a level of interference caused by the first UE.Type: ApplicationFiled: January 13, 2020Publication date: April 14, 2022Applicant: Apple Inc.Inventors: Dawei YING, Hassan GHOZLAN, Daewon LEE, Qian LI, Geng WU

Publication number: 20220109536Abstract: Disclosed herein are system, method, and computer program product embodiments verifying legitimate victim-aggressor pairs in remote interference management operation. In an embodiment, a first even report is generated by a victim base station based detection of an atmospheric duct and it transmits a victim reference signal with the first event report. The first event report includes an ID of the victim base station. An aggressor base station is triggered to begin monitoring for transmission of the victim reference signal. The aggressor base station sends a second event report if it detects the victim reference signal. The central entity tries to verify that the victim and aggressor are legitimate. If the verification passes, then the central entity sends a message to the aggressor to start of remote interference mitigation. If verification fails, the remote interference mitigation is not triggered and the victim reference signal is ignored.Type: ApplicationFiled: February 17, 2020Publication date: April 7, 2022Applicant: Apple Inc.Inventors: Hassan GHOZLAN, Dawei YING, Qian LI, Geng WU
