Publication number: 20260303475Abstract: The disclosure relates to a ML-based method for determining a CCE aggregation level for a UE in a PDCCH. The method comprises obtaining RBS traces. The method comprises training, using first data obtained from the traces, a machine learning model to predict a probability of discontinuous transmission (DTX) “isDTX probability”. The method comprises inputting second data obtained from the traces into the machine learning model, obtaining the isDTX probability and expanding the second data with the isDTX probability. The method comprises, for each of a plurality of probability thresholds (PTs) and for each of a plurality of strategies, selecting a data having an isDTX probability greater or equal to the PT and best satisfying the strategy and using the data to train a classifier. The method comprises selecting one classifier and using the classifier for determining the CCE aggregation level for the UE in the PDCCH.Type: ApplicationFiled: April 18, 2023Publication date: October 1, 2026Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Dawei NI, Aaron CALLARD, Yimin NIE, Aydin SARRAF

Publication number: 20260280789Abstract: Various embodiments disclosed herein provide for a method and apparatus to configure different User Specific Search spaces (USSs) for Physical Downlink Control Channel (PDCCH) candidates for different User Equipment devices (UEs). By selecting different USS configurations for different UEs, the search spaces can cover fewer symbols that there can be more PDCCH candidates in each symbol. By configuring each UE with a selected USS, the PDCCH capacity can be improved by optimizing Control Channel Element (CCE) utilization and improving downlink capacity by increasing the number of symbols used for Physical Downlink Shared Channel (PDSCH) use.Type: ApplicationFiled: April 5, 2023Publication date: September 17, 2026Inventors: Hong Ren, Björn Nordström, Haomin Li, Patrick Lie Chin Cheong, Aaron Callard

Patent number: 12634186Abstract: Systems and methods are disclosed herein for a Convex Reduction of Amplitude (CRAM) based processing scheme for a Multiple Input Multiple Output (MIMO) Orthogonal Division Multiplexing (OFDM) transmitter system. In one embodiment, a method performed by a processing system for a MIMO OFDM transmitter system comprises precoding frequency-domain input signals to provide frequency-domain precoded signals for multiple subcarriers. The method further comprises processing the frequency-domain precoded signals in accordance with a CRAM-based processing scheme to provide time-domain precoded signals for respective transmit branches of the MIMO OFDM transmitter system. The CRAM-based processing scheme uses projection matrices for the subcarriers, respectively, to project clipping energy into a null space of the MIMO OFDM transmitter system. Further, the projection matrices are a function of static or semi-static information that defines the null space of the MIMO OFDM transmitter system.Type: GrantFiled: September 8, 2020Date of Patent: May 19, 2026Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Pierre-Andre Laporte, Aaron Callard

Patent number: 12238745Abstract: Data is scrambled at a transmitter according to one of a number of predetermined scrambling sequences which are associated with a particular one of a number of predetermined transmit antenna diversity schemes (i.e., a specific number of transmit antenna ports). Received data is decoded using one or more of the known transmit antenna diversity schemes and the scrambled data is descrambled according to a corresponding descrambling sequence (related to the scrambling sequence). Based on the descrambled data, the receiver determines which transmit antenna diversity scheme (i.e., the number of antenna ports) is used by the transmitter. In one specific embodiment, CRC parity data is scrambled in the transmitter and the receiver descrambles the recovered CRC parity data according to a descrambling sequence, computes CRC parity data from the received data, and compares the descrambled CRC parity data to the newly computed CRC parity data.Type: GrantFiled: July 10, 2023Date of Patent: February 25, 2025Assignee: BlackBerry LimitedInventors: Aaron Callard, Jianglei Ma

Publication number: 20240267152Abstract: Systems and methods of the present disclosure are directed to a method performed by a network node. The method includes determining whether Physical Channel (PCH) blocking has occurred for consecutive Transmission Time Intervals (TTIs) on a cell controlled by the network node, wherein PCH blocking occurs when Wireless Communication Devices (WCD) served by the cell cannot be scheduled for transmission in the cell due to unavailability of PCH resources in one or more consecutive TTIs. The method includes adjusting a target Block Error Rate (BLER) for link adaptation for a plurality of WCDs served by the cell based on whether PCH blocking has occurred for the plurality of consecutive TTIs on the cell to obtain a modified target BLER for link adaptation for the plurality of WCDs served by the cell.Type: ApplicationFiled: June 15, 2021Publication date: August 8, 2024Inventors: Akram BIN SEDIQ, Aaron CALLARD

Patent number: 10638274Abstract: Systems and methods are disclosed herein for an enhanced Multimedia Broadcast Multicast Service (MBMS) in a wireless communications network. In one embodiment, a number of base stations in a MBMS zone, or broadcast region, accommodate both Spatial Multiplexing (SM) enabled user elements and non-SM enabled user elements. In another embodiment, a number of base stations form a MBMS zone, or broadcast region, where the MBMS zone is sub-divided into an SM zone and a non-SM zone. In another embodiment, the wireless communications network includes multiple MBMS zones. For each MBMS zone, base stations serving the MBMS zone transmit an MBMS zone identifier (ID) for the MBMS zone. The MBMS zone ID may be used by a user element for decoding and/or to determine when to perform a handoff from one MBMS zone to another.Type: GrantFiled: June 11, 2019Date of Patent: April 28, 2020Assignee: Apple Inc.Inventors: Jianglei Ma, Aaron Callard, Ming Jia, Wen Tong, Peiying Zhu, Hang Zhang
