Abstract: A method performed by a wireless device. The wireless device sends an indication to a network node including a value corresponding to a size of a buffer of detected or expected to be had during inactive state at a time of one or more transmissions. The sending is performed with the proviso that the size of the buffer is smaller than a threshold. The wireless device receives a grant from the network node based on the indication, and then sends data to the network node during inactive state, according to the grant received. The sending of the data is performed with the proviso that the size of the buffer is smaller than the threshold. The sending of the indication is performed prior to the sending of one or more data packets comprising at least a part of the first data.

Abstract: Methods, User Equipment (UE), and source network node for resuming a Radio Resource Control (RRC) connection to a target cell in a wireless communications network. The UE generates a security token using a set of input parameters and sends a resuming request with the security token to a target network node serving the target cell.

A wireless device (e.g., a user equipment) can provide an indication to a network node (e.g., a base station) to indicate that the wireless device will prioritize energy consumption reduction over some network requirements (e.g., latency and/or scheduling flexibility requirements). Accordingly, the wireless device can perform certain power-saving actions to reduce energy consumption. The network node, upon receiving the indication from the wireless device, can perform certain network-related actions to assist the wireless device in reducing energy consumption. As a result, it is possible for the wireless device to reduce energy consumption and complexity, thus helping to prolong battery life in the wireless device.

Abstract: Methods, User Equipment (UE), and source network node for resuming a Radio Resource Control (RRC) connection to a target cell in a wireless communications network. The UE generates a security token using a set of input parameters and sends a resuming request with the security token to a target network node serving the target cell. When receiving the resuming request, the source network node generates a security token using a set of input parameters in the same manner as the UE. If the received security token is successfully verified when compared with the generated security token, the source network node provides to the target network node a UE context of the UE, to enable the target network node to resume the RRC connection.

Abstract: The present disclosure relate to a method performed by a UE (102) for handling an invalid SI signature in a communication system. The UE obtains SI and an associated SI signature for a cell. The UE (102) determines if the obtained SI signature is valid or invalid. If the signature is valid, the UE (102) determines to use the cell. If the SI signature is invalid, the UE (102) determines if the UE (102) is configured to bar cells or not. If the SI signature is invalid and if the UE (102) is not configured to bar cells with invalid SI signature, the UE (102) determines to use the cell. If the SI signature is invalid and the UE (102) is configured to bar cells with invalid SI signature, the UE (102) determines to bar the cell and select another cell to use.
