Abstract: A client device and a corresponding method for detecting and indicating non-fulfilment of latency requirements of uplink data packets associated with an application are provided. The client device monitors transmissions of uplink data packets associated with the application, in a first layer, for non-fulfilment of latency requirements of the uplink data packets. The monitoring is based on a Quality-of-Service (QoS) monitoring configuration. Upon detection of a non-fulfilment of a latency requirement, the client device provides a first indication to a second layer. The first indication provides an early warning about non-fulfillment of latency requirements of uplink data packets. According to the application, the client device is allowed to take precautionary actions to counteract possible negative consequences of the non-fulfillment of latency requirements.

Abstract: The application relates to maintaining time-synchronization of a wireless connection between a network access node and a client device. The wireless connection may be configured for services with latency constraints. In one example, based on an expiry of a time alignment timer for the client device, the network access node transmits a control message to the client device. The control message instructs the client device to transmit a response signal to the network access node. The response signal can be used by the network access node to determine the timing advance for the wireless connection and adjust the timing advance.

Abstract: The disclosure relates to early detection and indication of a Quality-of-Service (QoS) non-fulfillment in one or more radio links serving an application. A client device monitors for a QoS non-fulfillment in the one or more radio links based on a QoS monitoring configuration associated with the application. The QoS monitoring configuration may be received from a network node and/or derived based on a predefined rule. Upon detection of a QoS non-fulfillment of one or more QoS requirements obtained from the QoS monitoring configuration, the client device provides a QoS non-fulfillment indication to the application. The QoS non-fulfillment indication gives the application an early warning about QoS non-fulfillment on the one or more radio links. Thereby, allowing the application to take precautionary actions to counteract possible negative consequences of the QoS non-fulfillment. Furthermore, the disclosure also relates to corresponding methods and a computer program.

Abstract: The present disclosure relates to a network access node and a client device for content type indication. The network access node selects a subset of bits among a set of bits in a second data packet associated with the first data packet based on the content type for the first data packet. The network access node scrambles the selected subset of bits with a first scrambling sequence associated with an identity of the client device. The network access node transmits the first data packet and the second data packet to the client device (300). Upon reception of the first data packet and the second data packet, the client device descrambles the scrambled subset of bits in the second data packet using a first scrambling sequence associated with an identity of the client device to determine the content type for the first data packet.

Abstract: The disclosure provides methods, devices, and non-transitory computer-readable storage media. An example method includes determining a transmission configuration indication (TCI) state update for an active joint TCI state upon detecting or predicting a rotation of the first communication device around at least one rotational axis of the first communication device. The active joint TCI state associates at least one reception spatial filter of the first communication device with at least one transmission spatial filter of a second communication device, or at least one transmission spatial filter of the first communication device with at least one reception spatial filter of the second communication device. The example method further includes transmitting a TCI update message to the second communication device. The TCI update message indicates the TCI state update.

Abstract: A client device and a corresponding method for detecting and indicating that a Quality-of-Service (QoS) estimate for a radio link serving an application does not fulfill a QoS requirement associated with the application is provided. The client device monitors QoS estimates for a radio link serving an application in the physical layer. The monitoring is based on a QoS monitoring configuration associated with the application. Upon detecting that a QoS estimate does not fulfill a QoS requirement obtained from the QoS monitoring configuration, the client device provides a first indication to a second layer arranged above the physical layer. The first indication provides an early warning that the radio link does not fulfill the QoS requirement. According to the application, the client device is allowed to take precautionary actions to counteract possible negative consequences of the non-fulfillment of the QoS requirement.

Abstract: A first client device compresses a broadcast sidelink packet according to a configuration for a compression profile by removing at least one non-IP header of the broadcast sidelink packet. The first client device transmits the compressed broadcast sidelink packet together with an indication of the compression profile. When a second client device receives the compressed broadcast sidelink packet, the second client device reconstructs the at least one non-IP header of the broadcast sidelink packet based on the configuration for the compression profile and the indicated compression profile.
