Abstract: According to certain embodiments, a method performed by a network node comprises transmitting a transmission of system information. The transmission comprises coded bins obtained by reading from a circular buffer. The transmission is transmitted in a first set of subframes corresponding to subframes #4 of a plurality of radio frames. The method further comprises transmitting an additional transmission of the system information. The additional transmission comprises additional coded bits obtained by continuing reading from the circular buffer. The additional transmission is transmitted in a second set of subframes corresponding to subframes of the plurality of radio frames other than subframes #4.

Abstract: A method performed by a first network node operating in a wireless communications network is described herein. The first network node initiates sending a first indication to a first wireless device operating in the wireless communications network using NB-IoT. The first indication indicates that a first carrier, the first carrier being a standalone Narrow Band-Internet of Things, NB-IoT, carrier operating within a New Radio, NR, carrier, is: a) deployed in one of: a guardband mode and an inband mode, and b) shifted away by a frequency offset from a frequency channel raster grid used by the first wireless device.

Abstract: An apparatus, method and wireless device for fast scanning of a wireless communications medium are disclosed. According to one aspect, a method includes tuning a transceiver of the wireless node to a first frequency. The method further includes computing a first difference frequency, the first difference frequency being a difference between the first frequency and a second frequency. The method further includes generating a first control signal to configure a first backscattering device to switch between at least two states at a switching frequency equal to the first difference frequency.

Abstract: A method for a user equipment, a method for a network equipment, a user equipment and a network equipment is disclosed. The network equipment transmits a signal pertaining to if control information is present in a first time period while the user equipment determines if a signal pertaining to control information is present in a first time period. The network equipment transmits control information to a UE in accordance with the transmitted signal while the user equipment decides whether to attempt to decode the control information depending on the determination.

Abstract: A method and network node for providing support for frequency-overlapping carriers among a first radio access technology, RAT, and a second RAT is provided. Second RAT information to signal to the first RAT wireless device is determined. The second RAT information configured to allow the first RAT wireless device to determine, at a resource element level, resources reserved for second RAT transmissions. The second RAT information is caused to be communicated to the first RAT wireless device.

Abstract: A wideband carrier (e.g., LTE carrier) is shifted up or down in frequency, within an allocated frequency band, by an integer multiple of the channel raster spacing (e.g., 100 KHz). This reduces the size of the guard band on one side of the carrier, and expands the guard band on the other side. A narrowband carrier (e.g., NB-IoT carrier) is then deployed within the expanded guard band, at or near a frequency such that the transmission is orthogonal to the wideband carrier transmissions, such as by using a shared N frequency grid spacing (e.g. at 100 KHz spacing, and using 15 KHz subcarriers). The narrowband carrier thus maintains orthogonality with the wideband carrier, but has “room” within the expanded guard band to both transmit on a frequency close to the frequency grid spacing, and to boost transmit power (e.g., by 6 dB), while remaining within the spectral mask. The shifted wideband carrier is transparent to wideband UEs, as the frequency shift is an integer multiple of the channel raster spacing.

Abstract: A method, system and apparatus are disclosed. A method implemented in a wireless device configured to communicate with a network node is provided. A first indication is received from the network node indicating a first restriction, where the first restriction is related to a maximum data rate computation for at least one carrier and is different from a legacy restriction. A second indication is transmitted to the network node indicating a plurality of capability parameters, where the plurality of capability parameters violates the legacy restriction and is in accordance with the first restriction. The network node is communicated with on the at least one carrier according to a maximum data rate determination associated with the indicated plurality of capability parameters.

Abstract: There is provided a method performed by a wireless device for communicating with a network node in a wireless communication network. The method includes using a field in a Master Information Block (MIB) received by the wireless device, as an indication of a presence of an extended MIB (eMIB) and identifying which candidate resource of at least one candidate resource that contains the eMIB based on the indication of the presence of the eMIB. There is also provided a corresponding wireless device for communicating with a network node, a method perform by a network node, and a network node.
