摘要： Methods and apparatuses are disclosed radio resource management (RRM) measurement. In one embodiment, a network node is configured to obtain neighbor relation information associated with a wireless device (WD) and/or a location of the WD; and determine whether to configure the WD in a limited search mode based on the obtained neighbor relation information. In another embodiment, the WD is configured to receive a configuration for a limited search mode; and perform measurements associated with neighboring cells based on the received configuration.

摘要： A network node transmits a scheduling configuration, over a Single Cell Multicast Control Channel, that indicates whether a single transport block or multiple transport blocks of a Single Cell Multicast Traffic Channel are scheduled. The network node may then transmit a transport block in accordance with the scheduling configuration. Correspondingly, a user equipment receives the scheduling configuration. The UE may then receive a transport block in accordance with the scheduling configuration.

摘要： A method is performed by a network node. The method comprises determining to use an extended random access preamble identifier, RAPID, for a random access procedure with a wireless device. The method further comprises transmitting a medium access control, MAC, protocol data unit, PDU. The MAC PDU comprises a header and one or more random access responses, RARs. Each RAR is associated with a corresponding subheader within the header of the MAC PDU. The random access procedure is associated with a first RAR of the one or more RARs and the extended RAPID for the random access procedure is indicated by a combination of one or more bits in the first RAR and one or more bits in the subheader that corresponds to the first RAR.

摘要： 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.

摘要： Method by a first network node in a wireless communications network. The network comprises a first group of wireless devices supporting transmission with a first bandwidth under a threshold and a second group supporting transmission with a second bandwidth over the threshold. The first network node configures a wireless device in the first group having a first set of time-frequency resources to carry a first type of information with: at least one second set to carry a second type. The second type is to be transmitted simultaneously to the first group. The first type is to be transmitted to at least one of: i) the first group and the second group, and ii) the wireless device. The first set and the at least one second set of time-frequency resources are in different sets of frequencies or are in different transmission time periods, or both.

摘要： 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.

摘要： According to certain embodiments, a method performed by a wireless device includes transmitting, to a base station, a first transmission of a message, which includes user data and information to setup or resume a connection between the wireless device and the base station. DCI comprising an uplink grant indicating a plurality of transport block sizes is received from the base station. The DCI is interpreted based on previous information received in a message from the base station. One of the transport block sizes is selected for retransmission of the message. The message is retransmitted using the selected transport block size and includes either only the information to setup or resume the connection or the information to setup or resume the connection and user data. The message is retransmitted using the selected transport block size.

摘要： 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.

摘要： Systems and methods for configuring Narrowband Positioning Reference Signals (NPRS) for NB-IoT are provided. A network node generates and transmits NPRS configuration information including a first NPRS bitmap for FDD mode and/or a second NPRS bitmap for TDD mode. A wireless device can determine a NPRS configuration in accordance with the second NPRS bitmap for TDD mode and perform measurements using the NPRS configuration.
