Patent number: 12256251Abstract: Methods, a first, and a second network node as well as a user equipment for exchange of measurement period related parameters are provided. The user equipment performs a method for measuring a measurement quantity of a secondary cell on a second carrier operated by a second radio network node. The user equipment receives, from the second radio network node, an indication indicative of the second carrier and a first parameter indicating a measurement period for measuring the measurement quantity of the secondary cell. The user equipment measures said measurement quantity on the secondary cell on the second carrier over the measurement period. The measurement period is a predefined value times the first parameter.Type: GrantFiled: December 19, 2023Date of Patent: March 18, 2025Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Muhammad Kazmi, Tao Cui

Publication number: 20250056420Abstract: A wireless device performs an uplink transmission, such as an idle-mode uplink transmission using preconfigured uplink resources (PUR). The wireless device determines whether a serving-cell signal measurement M2 was completed within a predetermined range of time before a reference time T2, the reference time T2 corresponding to an uplink transmission opportunity. Responsive to determining that the serving-cell signal measurement M2 was not completed within the predetermined range of time, the wireless device either defers transmission to a subsequent transmission opportunity, or drops the uplink transmission, or collects an additional serving-cell measurement M2? that falls within the predetermined range of time, for use in validating a TA for transmitting at the transmission uplink opportunity and/or for estimating a PL for power control of a transmission at the uplink transmission opportunity.Type: ApplicationFiled: August 20, 2024Publication date: February 13, 2025Inventors: Santhan Thangarasa, Gerardo Agni Medina Acosta, Muhammad Kazmi, Sandeep Narayanan Kadan Veedu
