摘要： The present disclosure relates to coverage monitoring and in particular it relates to determining radio coverage using correlated radio condition measurements and position estimates, for example for small cell deployment in a building. The disclosure relates to methods for coverage determination as well as to corresponding devices and computer programs. According to some aspects, the disclosure proposes a method, performed in a node 10, 110 of determining radio coverage of at least one small cell base station in a wireless communications network. The method comprises the steps of obtaining radio condition measurements, wherein a respective first time value is associated to each radio condition measurement. The method further comprises obtaining position estimates defining the position of a wireless device performing the radio condition measurements, wherein a respective second time value is associated to each position estimate and determining radio coverage by correlating each radio condition measurement to one of the obtained position estimates using the first and second time values.

摘要： A user equipment receives a signal indicating a time schedule for intermittent transmission of information from a base station managing a cell. The intermittent transmission of information enables the UE to perform mobility measurements when the cell is in a discontinuous transmission (DTX) mode and the UE is an active terminal not served by the cell. The UE performs, based on the intermittent transmission of information, a mobility measurement when the cell is in the DTX mode and reports the mobility measurement to the base station.

摘要： An approach of handling interference caused by inter-modulation in a network node for wireless communication capable of communication with a set of stations for wireless communication is disclosed. The stations are wireless transceiver devices and communication from the network node to any of the stations is considered to be downlink communication performed on a downlink carrier in a downlink carrier frequency band and communication from any of the stations is considered to be uplink communication performed on an uplink carrier in an uplink carrier frequency band. The method comprises, when an interference level indicates probable inter-modulation interference, scheduling uplink transmission grants for a plurality of stations of a subset of the stations within a time interval, such that scheduling outside the time interval is reduced. The uplink transmission grants are valid for the time interval, wherein the scheduling uplink transmission grants is performed by adapting a schedule for at least one station of the plurality of stations of the subset of the stations to fall within the time interval. The method further comprises transmitting the uplink transmission grant to the plurality of stations of the subset of stations, assigning limited transmissions on the downlink carrier frequency band at the time interval such that inter-modulation interference is reduced on the uplink carrier frequency band during the time interval, and assigning transmissions on the downlink carrier frequency band outside the time interval with less limitations than during the time interval. The approach comprises methods, network nodes, computer programs and network node sites.

摘要： There is provided mechanisms for shaping transmission beams in a wireless communications network. A method is performed by a network node. The method comprises acquiring channel measurements for wireless devices served by radio access network nodes using current beam forming parameters and being controlled by the network node. The method comprises determining, based on the channel measurements, desired beam forming parameters for shaping the transmission beams for at least one of the radio access network nodes. The method comprises initiating a gradual change of the current beam forming parameters to the desired beam forming parameters for shaping the transmission beams for the at least one of the radio access network nodes. The gradual change causes a need for network controlled handover to occur for at least some of the wireless devices served by the radio access network nodes.

摘要： A method performed by a master node, for handling Bluetooth connections to slave devices is provided. The master node allocates to a first group, a first set of channels, and to a second group a second set of channels. The first set of channels relates to a first part of a frequency band supported by the master node, and the second set of channels relates to a second part of the frequency band that is different from the first part of the frequency band. The master node assigns to the first group, a first connection between the master node and a first slave device, to use channels comprised in the first set of channels. The master node then attenuates for the connection in the first group, signals relating to any other group being allocated a set of channels, including the second group.

摘要： A mixed numerology OFDM system is presented herein relative to a first OFDM numerology having a first subcarrier spacing and associated with a first signal having a first length. A second signal having a second length and associated with a second OFDM numerology having a second subcarrier spacing greater than the first subcarrier spacing is generated by generating a sub-frame comprising redundant data appended to each of a plurality of OFDM symbols and generating the second signal by appending group redundant data to the sub-frame such that the second length equals the first length. The number of OFDM symbols in the sub-frame is selected such that a length of the sub-frame is as large as possible without exceeding the length of the first OFDM symbol in the first signal. The receiver may extract the first the first and second signals from a received composite signal using a single FFT.

摘要： A transmitting device encodes information bits of a first type of information and a second type of information into a codeword. The transmitting device interleaves the encoded information bits of the first type of information according to a first interleaving pattern and the encoded information bits of the second type of information according to a second interleaving pattern, thereby changing an order of the encoded information bits of at least one of the first type of information and the second type of information in the codeword and generating an interleaved encoded information bit sequence. At least one of the first and the second interleaving pattern is designed to allow the information bits of a first type of information to be decoded without knowing a length of the codeword. The transmitting device then transmits the interleaved encoded information bit sequence to a receiving device.
