摘要： A method performed by a wireless device for a Synchronization Signal Block Measurement Time Configuration (SMTC) window and measurement gap configuration includes receiving at least one configuration parameter for the SMTC window and/or a measurement gap from a network. The wireless device performs an adjustment of the SMTC window and/or the measurement gap based on the at least one configuration parameter and transmits the adjustment to the network. The wireless device measures at least one synchronization signal based on the adjustment to the SMTC window and/or the measurement gap.

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： A method is performed by a wireless device for performing a random access. In response to a received paging transmission, and when certain conditions are met, the wireless device randomly selects a random access resource from a plurality of available random access resources. The available random access resources may be spread in time, or in frequency, or in time and frequency. The wireless device then transmits a random access signal on the selected random access resource.

摘要： Methods performed by wireless devices and base stations for performing GNSS-assisted measurement reporting are disclosed. A method performed by a wireless device includes: determining that a measurement reporting triggering condition has been satisfied based on at least a location of the wireless device, the location of the wireless device being determined using GNSS location measurements; determining one or more measurement quantities relating to satellite(s) for each of the plurality of surrounding cells; and reporting at least a subset of the measurement quantities. A method performed by a base station includes: signalling to a wireless device a measurement report triggering condition, the measurement reporting triggering condition being based on at least a location of the wireless device, the location of the wireless device being determined using GNSS location measurements; and receiving a measurement report from the wireless device when the measurement reporting triggering condition is satisfied.

摘要： Enabling a UE to determine whether the UE can skip the acquisition of SIB1-BR. An indication (e.g., a one bit flag) in the MIB is provided, which indication is set to a particular value if the UE needs to read SIB1-BR, otherwise the indication is set to a different value indicating that the UE can skip reading SIB1-BR assuming other conditions are met (e.g., assuming that the UE has previously read SIB1-BR within a MIB indication time period).

摘要： Embodiments of the disclosure provide methods and apparatus for positioning in a wireless network. One embodiment provides a method, performed by a target device, for enabling detection of a narrowband positioning reference signal, NPRS, location in a radio frame. The method includes: obtaining, from a location server, assistance data related to a neighbour cell in a reference and neighbour cell list. The assistance data includes timing offset information for the neighbour cell; determining a time of a NPRS subframe for the neighbour cell and/or NPRS sequence based on the timing offset information; measuring a positioning reference signal (PRS) based on the determined time; and reporting the measured PRS to the location server.

摘要： A method, system and apparatus are disclosed. In one or more embodiments, a network node for communicating with a wireless device is provided. The network node includes processing circuitry configured to receive measurement capability information of a wireless device where the measurement capability information indicates an ability to perform a global navigation satellite system, GNSS, measurement. The processing circuitry is further configured to determine a GNSS measurement gap configuration during which the wireless device is to perform at least one GNSS measurement during at least one GNSS measurement gap where the GNSS measurement gap configuration is based at least in part on the received measurement capability information, and indicate the GNSS measurement gap configuration to the wireless device.

摘要： A method of operating a wireless device in a wireless communication network includes receiving a first reference signal at a first reception time from a first network node, receiving a second reference signal at a second reception time from a second network node, receiving a first indication of a first reference time, receiving a second indication of a second reference time, and transmitting a report to a serving network node. The indications of the first and second reference times indicate timings of frame structures of the first and second network nodes, respectively. The report is based on a first representation of a difference between the first reception time and the second reception time. The first representation is further based on the indications of the first and second reference times. Also provided are related devices and methods.
