Abstract: A method of controlling an indication of user data in a buffer of a User Equipment (UE) is provided. The user data is for Small Data Transmission (SDT) when the UE is in inactive mode. Based on a threshold value related to an amount of the user data for SDT, the UE determines whether to include an indication into a first uplink grant allocation transmission. The indication would indicate that user data is in the buffer. When an indication of user data in a buffer is not included in the first uplink grant, this indicates that the amount of data left in the buffer is less than the threshold value minus the first allocated grant transmission size, and when an indication of user data in a buffer is included, the indication indicates how many further transmissions are needed for transmitting the rest of the pending data.

Abstract: A method performed by a user equipment (UE) for handling communication in a wireless communications network is described. The UE obtains an indication of a first size of a grant for a first type of data transmission and transmits an access request to a radio network node to perform data transmission of the first type of data transmission. Then the UE receives a grant from the radio network node. The grant indicates a size for granted data transmission, or comprises a type indication of type of data transmission of the granted data transmission. The UE compares the first size with the indicated size in the grant, or the first type of data transmission and the type of data transmission indicated by the type indication in the received grant and based on the comparison, determines whether to use the received grant for performing data transmissions or not.

Abstract: The load on Random Access channels (N)PRACH (i.e., Msg1) is temporally distributed, to better handle synchronized access peaks from machine type devices. Access attempts by wireless devices are distributed in time, based on their identities (e.g., IMSI, which is used for the distribution of paging load) or random draw. The distribution restricts when 5 wireless devices can access the network, either based on System Frame Number or on random access occurrence. The method is implicit, i.e., after the initial System Information (SI) acquisition, wireless devices will automatically apply temporal network access load distribution according to the configuration provided in SI without any need for explicit signaling or re-acquisition of SI. Embodiments of the invention may be advantageously applied to any wireless 10 communication network supporting machine type communications, such as GPRS/EGPRS/ECGSM-IoT and UMTS/HSPA, as well as non-3GPP radio access technologies such as LoRa, Sigfox, and Ingenu.

Abstract: A method performed by an apparatus for handling a User Equipment access to a radio communications network is provided. The UE is using reduced capabilities. The reduced capabilities relate to reduced capabilities for communication in the radio communications network. The apparatus obtains information about a subscriber profile of the UE. When the UE accesses to the radio communications network using reduced capabilities, the apparatus determines whether or not the UE is authorized to access the radio communications network by using reduced capabilities, based on the obtained information about the subscriber profile of the UE.

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 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.

Abstract: A method performed by a network node for establishing a connection for data transmission between the network node and the wireless device in a wireless communication network is provided. The network node establishes that the wireless device is fixed. Fixed comprises always being served by the same one or more access points. The network node obtains a Timing Advance (TA) for transmissions between the network node and the wireless device, based on the distance between the network node and the wireless device. The obtaining of the TA is performed without Uplink (UL) transmission. The network node sends an indication to the wireless device, which indication indicates the obtained TA. The network node then establishes a connection for data transmission between the network node and the wireless device based on the sent TA in Radio Resource Control, RRC, signaling.

Abstract: A network node, a wireless device and methods therein, for decoding of contention based uplink transmissions of data in a cell served by the network node. The network node registers the wireless device for contention based uplink transmissions of data on a radio resource reserved for contention based uplink transmissions of data, e.g. when receiving a registration request sent from the wireless device, such that the wireless device is included in a set of wireless devices being registered for contention based uplink transmissions of data on the radio resource in the cell. The network node then performs blind decoding of uplink signals transmitted on the radio resource by considering the wireless devices in the set. In this way, the decoding is made more efficient by disregarding any other wireless devices in the cell which are not registered for contention based uplink transmissions of data on the radio resource in the cell.

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.
