  • Patent number: 12294902
    Abstract: Embodiments include methods for a network node of a 3GPP RAN. Such methods include determining a configuration that enables a UE to steer the UE's traffic between the 3GPP RAN and a WLAN without receiving a traffic steering command from the 3GPP RAN. The configuration includes a forward traffic steering configuration comprising a first plurality of thresholds/conditions for which the UE, when connected to 3GPP RAN, can initiate steering at least some of the UE's traffic from 3GPP RAN to WLAN; and a backward traffic steering configuration comprising a second plurality of thresholds/conditions for which the UE, when connected to WLAN, can initiate steering at least some of the UE's traffic from WLAN to 3GPP RAN. The backward traffic steering configuration includes threshold(s)/condition(s) based on different values of a same parameter as threshold(s)/condition(s) of the forward traffic steering configuration. The configuration is sent to the UE in a single message.

  • Patent number: 12206754
    Abstract: A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

  • Publication number: 20240414717
    Abstract: A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.

  • Publication number: 20240305988
    Abstract: A network node is configured for use in a wireless communication network. The network node is configured to acquire radio access capability information of a wireless device. The radio access capability information of the wireless device indicates radio access capabilities of the wireless device. The network node is configured to determine if the wireless communication network received the radio access capability information of the wireless device before access stratum security was activated for the wireless device. If the wireless communication network received the radio access capability information of the wireless device before access stratum security was activated for the wireless device according to that determination, the network node is configured to re-acquire the radio access capability information of the wireless device after access stratum security is activated for the wireless device.
