Abstract: A method by a first network node (111), for handling downlink transmission for a wireless device (130). The first network node (111) operates in a RAN (110). The first network node (111) obtains (201) data for transmission to the device (130). The first network node (111) has a context for the device (130). The device (130) is in inactive state. The first network node (111) sends (203) a first indication to a second network node (112) operating in the RAN (110) and to page or be paging the device (130) for the transmission. The indication indicates a size of the data. The first network node (111) refrains from sending the indication to other network nodes (113) operating in the RAN (110). The sending (203) of the indication is performed with the proviso that a previous indication has been obtained from the second network node (112) indicating the device (130) is in its serving area.

Abstract: A method, performed by a wireless device (130), for handling absence of an active connection to a network node (110). The wireless device (130) and the network node (110) operate in a wireless communications network (100). The wireless device (130) obtains (201) a first indication from the network node (110) indicating that the wireless device (130) is to perform an estimation, of a quality of a radio channel between the wireless device (130) and the network node (110), during a random access procedure in the absence of an active connection to the network node (110) and prior to receiving data from the network node (110). The wireless device (130) estimates (203), in the absence of the active connection, the quality of the radio channel and then sends (204), still in the absence of the active connection, another indication to the network node (110) indicating the estimated quality of the radio channel.

Abstract: A method (1000) is provided by a user equipment, UE (112), configured for Mobile Terminated-Small Data Transmission, MT-SDT for early Channel Quality Indicator, CQI, reporting. The method includes receiving (1002), before a Radio Resource Control, RRC, connection is established with a network node (110), information indicating at least one Reference Signal, RS. The UE receives (1004), from the network node, the at least one RS. Based on the at least one RS, the UE performs (1006) at least one CSI measurement. Before the RRC connection is established with the network node, the UE transmits (1008), to the network node, CSI associated with the at least one CSI measurement.

Abstract: Systems and methods are disclosed for random access during Configured Grant (CG) Small Data Transmission (SDT). In one embodiment, a method performed by a User Equipment (UE) comprises, while in an inactive state, transmitting, to a network node, a Radio Resource Control (RRC) Resume Request with first data using a CG occasion from among a plurality of CG occasions configured for the UE and determining that one or more criteria for performing a Random Access (RA) have been satisfied. The method further comprises, responsive to determining that the one or more criteria for performing a RA have been satisfied, performing a RA during which the UE retransmits the RRC Resume Request with the first data. In this manner, the UE does not have to wait for the next CG occasion to send a retransmission or time critical data, e.g., in the case of failure of the initial transmission.

Abstract: A method for handling a Mobile Terminating (MT) Small Data Transmission (SDT) from a network node to a user equipment (UE) in a wireless communications network. The UE receives a Downlink Control Information (DCI) from the network node. The DCI is identified when monitoring a Physical Downlink Control Channel (PDCCH) by means of a Cell-Radio Network Temporary Identifier (C-RNTI). The DCI indicates scheduled Downlink (DL) data related to the SDT. Further, the DCI is received when the UE has entered into an inactive mode. When the DCI has been received, the UE resumes the radio resources configured for a Configured Grant based SDT (CG-SDT) in the UE context, derives a new security key based on a security key present in the UE context, and when receiving the scheduled DL data related to the MT-SDT from the network node, the UE decrypts the DL data by means of the new security key.

Abstract: Embodiments include methods for a user equipment (UE) configured to operate in a cell served by a radio access network (RAN) node. Such methods include receiving at least the following information from the RAN node during a first procedure: downlink (DL) data associated with an application hosted by the UE, and a timing advance (TA) command applicable to UE uplink (UL) transmissions to the RAN node. Such methods include initiating a time alignment timer (TAT) in response to receiving the TA command. Such methods include, after completion of the first procedure and based on determining that the TAT has not expired, transmitting to the RAN node one or more messages according to a timing adjusted based on the TA command. Other embodiments include complementary methods for a RAN node, as well as UEs and RAN nodes configured to perform such methods.

Abstract: The present disclosure relates to a method performed by a network node (101) for handling Configured Grant-Small Data Transmissions, CG-SDT, resources in a communications system (100). The network node (101) provides a configuration for common CG-SDT resources to a User Equipment, UE (105). The common CG-SDT resources are common to multiple UEs (105). The network node (101) provides information indicating which SDT resource the UE (105) should use. The SDT resource is the common CG-SDT resources or other Mobile Originated-Small Data Transmissions, MO-SDT, resources.

Abstract: Systems and methods for implementing Discontinuous Reception (DRX) are provided. In some embodiments, a method performed by a User Equipment (UE) for implementing DRX includes: configuring a DRX scheme which is activated in certain conditions; implementing DRX at the UE during one or more of the group consisting of: from the time the UE receives an RRCRelease message; after the UE receives DL data; and until terminating a (MT-SDT) session. This can result in significant energy benefits at the UE end. Some embodiments enable DRX during the MT-SDT procedure. The advantage of the solution is reduced energy consumption by the UE by saving the energy spent by enabling DRX in the MT-SDT procedure.

Abstract: A method of providing wireless communications in a wireless network can include wirelessly receiving a chirp spread-spectrum modulated signal at a first gateway device, the chirp spread-spectrum modulated signal being transmitted by a remote client device. The chirp spread-spectrum modulated signal can be demodulated at the first gateway device to provide demodulated data at the first gateway device. The demodulated data can be processed to provide an indication that a decode of a packet including the demodulated data failed. Time adjacent chirps included in the demodulated data can be combined to provide combined data at the first gateway device. A message can be transmitted from the first gateway device to a remote server responsive to an amplitude of the combined data exceeding a threshold value and the indication that the decode of the packet including the demodulated data failed.
