    Abstract: A method for analyzing frequency resources within a predetermined multiplexing band. For at least one base station, capabilities for detecting uplink messages respectively in different frequency sub-bands within the multiplexing band are estimated. For each frequency sub-band, a predetermined service quality criterion is assessed depending on the detection capability estimated for the frequency sub-band. A spectral map of service quality for the base station is transmitted. The spectral map is representative of the frequency sub-bands for which the service quality criterion has been verified and the frequency sub-bands for which the service quality criterion has not been verified.

  • Patent number: 10651998
    Abstract: Networks use channel state information reference signals (CSI-RSs) to measure channel conditions between a user equipment (UE) and a transmit/receive point (TRP) in a cell. The resources configured for the transmission of a CSI-RS may be indicated to the UE using higher layer signaling. Measurement results for a CSI-RS are transmitted by the UE in the form of a measurement report. A need exists for signaling designs that aim to provide more flexible and efficient signaling of CSI-RS resource configurations and measurement reports. In some embodiments, CSI-RS resource configurations and measurement reports are resource-specific. The CSI-RS resource configurations may be independent from an identifier of the cell that the CSI-RS is transmitted from, and the measurement reports do not necessarily include the identifier of the cell. Advantages may include allowing the network to freely allocate CSI-RS resources without the need for reconfiguration at the UE side.

  • Patent number: 10582524
    Abstract: A method for a machine type communication (MTC) terminal to report a channel state information (CSI) in a wireless communication system, according to an embodiment of the present invention, comprises the steps of: selecting a set of M downlink subframes as a CSI reference resource for the MTC terminal; measuring a channel quality indicator (CQI) through the CSI reference resource; and transmitting a CSI report including the CQI to a base station through an uplink subframe, wherein the MTC terminal is configured to repeatedly receive an MTC signal by frequency-hopping N sub-bands among a plurality of sub-bands. The number ‘M’ of the downlink subframes to be included in the CSI reference resource is determined on the basis of an upper layer parameter received from the base station. Further, the MTC terminal may measure the CQI on the basis of a cell-specific reference signal (CRS) received through the M downlink subframes selected from a reference downlink subframe located before the uplink subframe.

  • Patent number: 10575307
    Abstract: In multi-beam operation, path losses or other aspects of electromagnetic signal propagation, may make it necessary to restrict certain beam directions used between two devices. A base station determines a restricted-beam set including at least one beam direction that is restricted for at least one of a signal transmission or a signal reception. The base station also restricts at least one of a transmission or a reception of a signal based on the restricted-beam set. Additionally, the base station determines an updated restricted-beam set including at least one beam direction that is restricted for at least one of transmission or reception of an electromagnetic signal. The base station also updates the restricted-beam set by adding or removing at least one beam direction to the restricted set corresponding to at least one of signal transmission or signal reception.

  • Patent number: 10555285
    Abstract: A machine type communication (MTC) gateway device is operable to provide usage type information to a 3GPP network entity and an application out of the 3GPP network. The disclosed MTC gateway device and base station provide an enhanced monitoring response with an enhanced positioning granularity to a position monitoring request. Exposure of usage type and subscription information associated with a user equipment (UE) device is a first step to virtual network function and network slice related provisioning and dedicated core network related provisioning for the UE device. Providing UE usage type through a network exposure function to a third party application enables the third party application to adapt for the usage type.
