Abstract: A method may be provided to operate a wireless terminal in communication with a network node. The method may include receiving a Physical Downlink Control Channel, PDCCH, order from the network node. The PDCCH order may include an identification for a Random Access CHannel RACH occasion to be used for a RACH message 1 preamble transmission. Moreover, the identification may include a first index that indicates a set of RACH occasions and a second index that indicates the RACH occasion associated with the set. The method may also include transmitting a Message 1 preamble to the network node using the RACH occasion responsive to the PDCCH order.

Abstract: A system and method for providing time domain allocations in a communication system. In an embodiment, an apparatus operable in a communication system and including processing circuitry is configured to receive an indication of a time domain allocation in downlink control information associated with a radio network temporary identifier (“RNTI”) identifying the apparatus, and employ the time domain allocation associated with the RNTI for transmissions associated with the apparatus. In another embodiment, an apparatus operable in a communication system and including processing circuitry is configured to associate a time domain allocation with a RNTI identifying a user equipment, and provide an indication of the time domain allocation in downlink control information to allow the user equipment to employ the time domain allocation associated with the RNTI for transmissions associated therewith.

Abstract: Embodiments herein relate to a method performed by a wireless device (10) for handling positioning of the wireless en device in a wireless communications 5 network (1). The wireless device (10) receives assistance data from a location node (15), or a radio network node (12), in the wireless communications network, wherein the assistance data comprises a positioning configuration comprising a start and/or stop information indicating when positioning reference signal, PRS, transmissions from the radio network node are started and/or ended. The wireless device measures, based on the assistance data, a positioning information of PRSs; and g transmits the measured positioning information to the location node or the radio network node.

Abstract: A method performed by a wireless device (WD) comprises receiving a control message. The control message indicating at least a Modulation and Coding Scheme (MCS) and a scaling factor for a downlink shared channel. The scaling factor indicates a value less than 1. The method further comprises determining a transport block size (TBS) based on the MCS and the scaling factor indicated in the control message. A method performed by a network node comprises indicating in a control message at least a Modulation and Coding Scheme (MCS) and a scaling factor for a downlink shared channel. The scaling factor indicating a value less than 1. The method further comprises sending the control message to a User Equipment (UE), the control message enabling determination of a Transport Block Size (TBS) for a shared downlink channel.

Abstract: A method in a network node includes communicating, over a narrowband Internet of Things downlink, a first message to a first wireless device during repetition periods of at least a first time frame and a second time frame of a plurality of time frames of a transmission time of a narrowband physical downlink control channel (NB-PDCCH) or a narrowband physical downlink shared channel (NB-PDSCH). Each time frame of the plurality of time frames includes a repetition period and a gap. The method also includes communicating a second message to a second wireless device during a gap of the first time frame.

Abstract: A user equipment (UE) is provided. The UE includes processing circuitry configured to rotate a symbol of a plurality of symbols for transmission. An amount of rotation of the symbol of the plurality of symbols is based on at least one of a cyclic prefix length of the symbol of the plurality of symbols and position of a subcarrier on which the symbol of the plurality of symbols is to be transmitted. The UE includes a transmitter configured to cause transmission of the plurality of symbols.
