Abstract: Systems, methods, and apparatus for communicating transport block repetitions are disclosed. An example method performed by a wireless device includes receiving an assignment of radio resources corresponding to two or more transmissions with first start and length pairs, each transmission comprising a transport block repetition, where at least one of the first start and length pairs violates a time-domain allocation restriction. The wireless device determines second start and length pairs for the two or more transmissions such that the time-domain allocation restriction is not violated. The wireless device transmits the two or more transmissions according to the determined second start and length pairs.

Abstract: Embodiments include methods for a network node in a RAN to support timestamping of time-sensitive network (TSN) messages received by a UE. Such methods include sending one of the following information to the UE for use in timestamping of TSN messages: a second indication of one of multiple available downlink propogation delay (DL PD) compensation methods that is selected by the network node the UE; or a DL PD compensation value, determined by the network node based on one of the available DL PD compensation methods selected by the UE on a different one of the available DL PD compensation methods selected by the network node for the UE. Such methods also include sending, to the UE proximately after sending the information, an indication of a system clock time, associated with the RAN, to be compensated by the UE based on the information.

Abstract: Embodiments include methods for a user equipment (UE) to transmit control information in association with a plurality of data packet repetitions. Such methods include selecting, from a plurality of configured starting transmit positions, a starting transmit position for an initial repetition of the plurality. Such methods include selecting a sequence of cyclic shift (CS) values from a plurality of configured CS values. The plurality of configured CS values are less than the plurality of repetitions and/or the plurality of configured starting transmit positions. The sequence is selected based on the plurality of repetitions, and on an identifier associated with the data packet and/or the selected starting transmit position. Such methods include transmitting the data packet repetitions beginning at the starting transmit position, wherein at least a subset of the repetitions are transmitted in association with demodulation reference signals (DMRS) that are cyclic-shifted according to CS values of the selected sequence.

Abstract: Embodiments herein disclose e.g. a method performed by user equipment, UE, (10) for handling uplink, UL, communications in a wireless communication network. The UE (10) receives from a radio network node (12), an indication with an uplink grant, wherein the indication indicates that a radio resource scheduled by the UL grant for UL transmission is for a type of data. The UE (10) uses the radio resource for transmission of that type of data.

Abstract: A wireless device, a Radio Access Network (RAN) node, and various methods are described herein for improving the coverage performance of the Extended Coverage (EC)-Random Access Channel (RACH). For instance, the wireless device, the RAN node, and various methods can improve the coverage performance of the EC-RACH by utilizing a new access burst (referred to herein as Extended Synchronization Access Burst (ESAB)), a new coding scheme (referred to herein as RACH11′) for the CC5 2TS EC-RACH, and/or an access burst mapping scheme for the CC5 2TS EC-RACH.

Abstract: A positioning node (e.g., SMLC), a Radio Access Network (RAN) Node (e.g., BSS/BTS), and a wireless device (e.g., MS) are described herein which implement procedures and corresponding modified or new messages/information elements/fields to reduce the possibility of a bandit (e.g., invalid or unauthorized) wireless device from triggering the RAN Node (e.g., BSS/BTS) to generate false timing advance (TA) information associated with the wireless device and report the false TA information to the positioning node (e.g., SMLC) which leads the positioning node (e.g., SMLC) to estimate with degraded accuracy a position of the wireless device.

Abstract: Method performed by a first network node (101), e.g. a SGSN or an MME. The first network node (101) initiates sending (401) a first paging request to a second network node (102), e.g. a node of a Base Station Subsystem (BSS), which indicates that a wireless device (141) served by the second network node (102) is to initiate cell reselection prior to sending a first response, based on the first paging request, wherein the wireless device (141) is to be paged for a positioning procedure, e.g. a timing advance (TA) multilateration.

Abstract: A wireless device 230 and a method therein for triggering a cell reselection procedure. The wireless device is served by a first Radio Network Node (RNN) 210, and the wireless device and the first RNN are operating in a wireless communications system 200. The wireless device determines a difference between a second signal parameter of a second signal and a first signal parameter of a first signal, wherein the first and second signal parameters are received from the first RNN. Further, the wireless device triggers a cell reselection procedure when the determined difference is larger than a first predetermined threshold value for the cell reselection procedure.
