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: A transmitting device and a receiving device for reliable reception of control messages such as downlink control information is provided. The transmitting device forms a control message which comprises control information, a first CRC word (W1) and a second CRC word (W2). The control message is sent to the receiving device which obtains a first CRC check outcome based on performing a first CRC check on the control message, and a second CRC check outcome based on performing a second CRC check on the control message. Thereby, more reliable reception of control messages is possible. Furthermore, the present application 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.
