  • PDCP UL Split and Pre-Processing
    Publication number: 20240057185
    Abstract: According to an aspect, a UE in an uplink split-bearer configuration is configured to transmit PDUs by a first RLC entity via a first uplink transmission path and/or by a second RLC entity via a second uplink transmission path. The UE determines a total amount of data volume from PDCP data volume and RLC data volume pending for initial transmission in the two RLC entities. The UE decides whether submission of PDCP data volume is allowed to either of the two RLC entities or to only the first RLC entity, based on whether the total amount of data volume meets or exceeds a first threshold. The UE also reports the PDCP data volume to both the first and second uplink transmission paths or only the first uplink transmission path, based on whether the total amount of data volume meets or exceeds a first threshold.

  • Method and apparatus used in transmission reliability
    Patent number: 11895514
    Abstract: A method for transmission reliability comprises receiving, from a first network node at a second network node, a message indicating that a first connection between the first network node and a terminal device has failed. The message comprises an indication to initiate a second connection with the terminal device from the second network node. The method further comprises establishing, at the second network node, the second connection with the terminal device based on the message. The second network node comprises a third connection established before the first connection failed. The first connection carries data transmitted in the third connection before the first connection failed, and the second connection carries data transmitted in the third connection after the first connection failed. The method for interference coordination utilizes duplicated transmissions to secure data transmission and to prevent data loss in an unexpected system failure.

  • Method, first network node, computer program and carrier for handling paging of wireless devices
    Patent number: 11856555
    Abstract: A method and a first network node of a wireless network, for handling paging of a wireless device. A Radio Access Network Area, RANA, which is supported by the first network node, is registered in a database by network nodes supporting the RANA, including the first network node. The network nodes that support the RANA are then identified in the database. When it is detected that a wireless device needs to be paged in the RANA, e.g. for receiving data, a paging message is distributed to the identified set of network nodes as an instruction to perform radio transmission of the paging message. Further, which is available to the network nodes throughout the wireless network. Thereby, any network node in the wireless network, such as the first network node, is able to perform distribution of a paging message to all network nodes that support a particular RANA, as registered in the database.
