Publication number: 20240138001Abstract: A first wireless communication device (401, 404), WCD, transmits a first indication to a second WCD (401, 404) or receives a first indication from the second WCD. The first indication indicates a first time period (501) during which the first WCD is expected to monitor for receipt of a transmission. The first WCD monitors for receipt of a transmission during the first time period. The first WCD is not expected to monitor for receipt of a transmission during a second time period (502) before the first time period begins. The first WCD performs the transmission or receipt of the first indication after a link has been established between the first WCD and the second WCD for relaying of information to and/or from a network via one or more sidelink transmissions between the first WCD and the second WCD.Type: ApplicationFiled: February 14, 2022Publication date: April 25, 2024Inventors: Andreas Höglund, Olof Liberg, Yi-Pin Eric Wang

Publication number: 20240129873Abstract: Systems and methods for determining timing advance (TA) validity are disclosed. In some embodiments, systems and methods are disclosed herein in which a wireless device implicitly considers a TA to be valid in a full cell when no TA validation mechanisms are explicitly configured. In other embodiments, systems and methods are disclosed herein in which a timer serves a dual purpose. If the timer is set to infinity, a wireless device will always consider a TA to be valid within a given cell, and at the same time will disable other TA validation mechanisms. Otherwise, the wireless device will interpret the timer as indicating for how long the TA value that the wireless device possesses is considered to be valid. Benefits of the solutions described herein include reducing signaling bits in the configuration and avoiding the possibility of conflicting configurations.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Inventors: Andreas Höglund, Gerardo Agni Medina Acosta, Sandeep Narayanan Kadan Veedu, Emre Yavuz

Publication number: 20230397035Abstract: A method performed by a wireless device. The method is for handling uplink transmission to a network node. The wireless device determines, in inactive state, whether a size of a buffer of data for uplink transmission obtained in inactive state is smaller than a threshold. The wireless device then sends, to the network node, at least a first transmission comprising a first subset of the data, and an explicit or implicit indication of a number of remaining transmissions that are needed to send the remaining data. The sending of the first transmission is based on a result of the determining and is in inactive state. The wireless device also sends the remaining transmissions in inactive or in connected state based on one or more further indications. The one or more further indications are received from the network node or configured.Type: ApplicationFiled: October 14, 2021Publication date: December 7, 2023Inventors: Luca FELTRIN, Andreas HÖGLUND, Tuomas TIRRONEN, Jan CHRISTOFFERSSON

Publication number: 20230397019Abstract: A method for relaxing Radio Resource Management (RRM) measurement is provided. The method comprises obtaining an indication for use in determining a stationary-mobility state of a user equipment (UE). The indication comprises one or more first criteria, which is based on a difference between a current signal level value and a reference signal value as compared to an adjusted threshold.

Publication number: 20230379905Abstract: A method of controlling an indication of user data in a buffer of a User Equipment (UE) is provided. The user data is for Small Data Transmission (SDT) when the UE is in inactive mode. Based on a threshold value related to an amount of the user data for SDT, the UE determines whether to include an indication into a first uplink grant allocation transmission. The indication would indicate that user data is in the buffer. When an indication of user data in a buffer is not included in the first uplink grant, this indicates that the amount of data left in the buffer is less than the threshold value minus the first allocated grant transmission size, and when an indication of user data in a buffer is included, the indication indicates how many further transmissions are needed for transmitting the rest of the pending data.Type: ApplicationFiled: October 20, 2021Publication date: November 23, 2023Inventors: Luca FELTRIN, Andreas HÖGLUND, Tuomas TIRRONEN, Jan CHRISTOFFERSSON, Henrik ENBUSKE
