Patent number: 11937340Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.Type: GrantFiled: March 14, 2023Date of Patent: March 19, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gunnar Mildh, Ingrid Nordstrand, András Rácz, Magnus Stattin, Pontus Wallentin

Patent number: 10715286Abstract: An inventive UE carrier aggregation (CA) capability reporting signalling model allows UEs (30) aggregating large numbers of component carriers to transmit CA-relevant capabilities to the network more efficiently than the current (legacy) signalling model. Rather than reporting CA/MIMO/CSI/NAICS capabilities separately for each supported band combination, including fallback configurations, embodiments of the present invention either report UE Radio Frequency (RF) and Baseband (BB) related capabilities separately, or report them disassociated from CA band configurations. This approach avoids the need to signal the full UE (30) set of capabilities for each of (possibly many) supported band combinations. Furthermore, fallback capabilities are signalled implicitly, eliminating the need to transmit this data.Type: GrantFiled: July 19, 2016Date of Patent: July 14, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Maomao Chen, Christian Bergljung, Tao Cui, Shaohua Li, Ingrid Nordstrand, Håkan Palm, Riikka Susitaival, Henning Wiemann

Patent number: 10264497Abstract: Methods and arrangements in a base station and a User Equipment are provided. The methods and arrangements relates to the scenario when the UE is handed over from a source base station to a target base station in a handover scenario, and wherein the target base station may not support functionalities which the source base station and the UE support. The method in the UE comprises receiving (501) a configuration message from the target base station via the source base station, configuring (502) the UE based on the received configuration message from the target base station by searching (503) for a second field in an information element of the received configuration message. The presence/non-presence or a value of the second field is indicative of how to manage a configured first functionality associated with an optical first field, wherein the configured first functionality may not be supported by the target base station.Type: GrantFiled: February 2, 2018Date of Patent: April 16, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Janne Peisa, Tao Cui, Ingrid Nordstrand, Mats Sågfors, Sven Ekemark

Patent number: 10004078Abstract: A network node (600), a wireless device (602) and methods for controlling a radio communication using carrier aggregation. The wireless device (602) sends (6:1) UE capabilities to the network node (600), indicating a maximum capability limit per component carrier and a total maximum capability limit across all component carriers to be used in the radio communication. The network node (600) further selects (6:2) a number of component carriers to be used by the wireless device, and configures (6:3) radio features on the selected component carriers based on the received UE capabilities. The network node (600) then signals (6:4) the selected number of component carriers and the configured radio features to the wireless device (602) for use in the radio communication (6:5). Thereby, the network node (600) can utilize the full capabilities of the wireless device (602) when configuring the radio features while still respecting both the maximum capability limit per carrier and the total maximum capability limit.Type: GrantFiled: December 21, 2015Date of Patent: June 19, 2018Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Håkan Palm, Lisa Boström, Tao Cui, Ingrid Nordstrand

Patent number: 9775080Abstract: A method in a first network node for handover preparation of a user equipment of a first category in a wireless communications network. The handover preparation is performed between a first cell served by the first network node and a second cell served by a second network node comprised in the wireless communications network. The first network node sends (301) to the second network node a message comprising information indicating a request for preparation of a handover of the user equipment. The request is specific for user equipment of the first category. The first network node receives (302) from the second network node a message indicating failure to prepare the handover. The first network node interprets (303) the message indicating failure to prepare the handover as an indication that the second network node does not support any user equipment of the first category.Type: GrantFiled: October 31, 2014Date of Patent: September 26, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Kai-Erik Sunell, Ingrid Nordstrand

Patent number: 9736658Abstract: A method performed by a network node for transmitting enhanced Multimedia Broadcast Multicast Services, eMBMS, control information to wireless devices in a wireless telecommunications network is provided. The eMBMS control information comprises MBMS Single Frequency Network, MBSFN, area configuration information and MCH Scheduling Information, MSI, for a Multicast CHannel, MCH. The MBSFN area configuration information and the MSI indicate Multicast Traffic Channels, MTCHs, for the eMBMS. The network node configures the indication of the MTCHs in the MBSFN area configuration information and in the MSI based on an order of logical channel identities of the MTCHs that is set in the network node. Then, the network node transmits the MBSFN area configuration information and MSI to the wireless devices in the wireless telecommunications network.

Patent number: 9693372Abstract: The embodiments herein relate to a method in an eNB for handling MBSFN area configuration information. The eNB receives, from a MME, a MBMS session start request. Based on the received request, the eNB computes a first time for a start of the MBMS session. The first time is a first MCC, update time. The eNB periodically sends, from the first time, the configuration information to a user equipment. The eNB stops the sending of the configuration information to the user equipment when the MBMS session is a last MBMS session. The eNB sends updated configuration information to the user equipment when the MBMS session is not the last MBMS session. The updated configuration information is updated MBSFN area configuration information.Type: GrantFiled: July 3, 2012Date of Patent: June 27, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Xiaoling Wang, Ingrid Nordstrand
