Patent number: 10693613Abstract: A wireless telecommunications system supports a DRX operating mode for communications between a base station and terminal device, which includes a regular repeating cycle of DRX inactive periods when the terminal device monitors a downlink channel from the base station and DRX active periods when the terminal device enters a power-saving mode not monitoring the downlink channel. The terminal device transmits uplink signaling, triggering subsequent downlink signaling, that may include acknowledgement signalling for a previous downlink transmission or an uplink transmission resources request. The base station receives the uplink signalling, determines time of an upcoming DRX inactive period for the terminal device, and delays transmitting downlink signalling responding to the uplink signalling until the upcoming DRX inactive period.Type: GrantFiled: May 15, 2014Date of Patent: June 23, 2020Assignee: CONVIDA WIRELESS, LLCInventors: Jussi Kahtava, Derek John Richards

Patent number: 10624057Abstract: A paging method in a wireless telecommunications system. A core network element selects a base station from plural base stations including a tracking area to have primary responsibility for paging a terminal device and conveys an indication of the terminal device to the selected base station. Each base station maintains a paging database identifying one or more terminal devices for which it has a responsibility for paging. When a terminal device is to be paged, the core network element transmits a paging request to the plural base stations including the tracking area. The respective base stations then determine whether to onward transmit a paging message for the terminal device based on a comparison between an identifier for the terminal device being paged with entries in their paging database, and if the comparison indicates it has responsibility for paging the terminal device, it will transmit a paging message accordingly.Type: GrantFiled: March 14, 2014Date of Patent: April 14, 2020Assignee: SONY CORPORATIONInventors: Stephen Truelove, Hideji Wakabayashi, Jussi Kahtava

Patent number: 10225856Abstract: Resources are allocated on a shared downlink control channel by an allocation table that is partitioned into a first, fixed length partition and into at least one second, variable length partition. The fixed length and the modulation and coding scheme MCS of the first partition is known a priori. The second variable length and the MCS of the second partition may be given in the first partition. Robustness may be varied between different second partitions of the same allocation table, or even within a single second partition to account for users at different proximity to the network node giving the allocations. Users may be identified in the first partition (e.g., a fixed number of users), and/or in the second partition (either additional allocated users or all users being allocated if the first partition does not identify users). Method, apparatus, computer program, integrated circuit and systems are detailed.Type: GrantFiled: May 11, 2007Date of Patent: March 5, 2019Assignee: Nokia Technologies OyInventors: Jussi Kahtava, Mika Rinne, Olav Tirkkonen
