Abstract: According to some embodiments, a method performed by a wireless device for mobile-terminated early data transmission includes receiving a paging message from a network node. The paging message comprises an indication that the network node will use early data transmission to transmit downlink data to the wireless device. In response to receiving the paging message, the method includes selecting an early data transmission preamble and transmitting a random access message 1 to the network node. The message 1 includes the selected early data transmission preamble.

Abstract: A method for improving data transmission security at a user equipment comprises receiving, from a source network node, a connection release message including instructions for computing a hash value for data to be included in a connection request message; computing the hash value based on the instructions included in the connection release message; calculating a token based on the hash value, and sending, to a target network node, the connection request message including the token. The method may further forward the data from the target network node directly to a gateway after the token has been verified. The method may reduce a signaling overhead by having a fixed-size hash value for data. Furthermore, the method may improve a transmission security by including the token in an RRC message, in which the token is calculated based on the hash value representing the data.

Abstract: Embodiments herein relate to a method performed by a network node in a telecommunication network providing a multicast transmission to a group of devices residing in a cell of the telecommunication network. The network node monitors a congestion level for communication, and, if the congestion level reaches a first threshold, the network node orders for at least one device in a RRC connected mode to be released from the RRC connected mode to an RRC idle mode or an RRC inactive mode, thereby disabling a capability of the at least one device to provide one or more re-transmission requests while keeping an ability of the at least one device to further receive the multicast transmission.

Abstract: A base station transmits a resource grant indicating a plurality of options from which a wireless device is permitted to select for use in transmitting user data on an uplink during random access. Each respective option comprises a transport block size (TBS) and a number of repetitions. One of the TBSs is a maximum permitted TBS and the other TBSs are derived from the maximum permitted TBS using a predefined set of smaller TBS values. The number of repetitions of each option is determined as a function of the maximum permitted TBS and a corresponding number of repetitions. The wireless device receives the resource grant and transmits the user data on the uplink during random access to the base station according to at least one of the options. The base station receives the user data on the uplink during random access correspondingly.

Abstract: A UE operating in a wireless network receives a paging message from the wireless network and performs a random access procedure in response to the paging message, where performing the random access procedure includes sending an indication of whether the UE will transmit a reply to an early data transmission from the wireless network to the UE. The network receives, as part of a random access procedure performed by the UE in response to the paging message, an indication of whether the UE will transmit a reply to an early data transmission from the wireless network to the UE.

Abstract: A network node is configured for transmitting a mobile-terminated early data transmission during a random-access procedure. The network node transmits a page having a contention-free preamble corresponding to an identity associated with a wireless device to be paged. The identity may be a Serving Temporary Mobile Subscriber Identity, S-TMSI, or a resume identity that identifies a suspended Radio Resource Control, RRC, connection. The network node then receives, as part of the random-access procedure, a Msg1 transmission that includes the contention-free preamble. The network node next transmits, as part of the random-access procedure, a Msg2 transmission to the wireless device associated with the identity corresponding to the contention-free preamble. The Msg2 transmission includes a signaling message and downlink data.
