A method and a spectrum owner system are described. The spectrum owner system records, in a distributed ledger network, a list of spectrum resources licensed from a regulatory authority system to the spectrum owner system. The spectrum owner system receives an authorization request for a spectrum allocation of spectrum resources, where the spectrum allocation includes at least a desired interval of time for usage of the spectrum resources by a radio access network of a spectrum renter, a desired location for usage of the spectrum resources by the radio access network, and additional characteristics of the spectrum resources. The spectrum owner system negotiates agreement terms for the desired spectrum allocation; and records, in the distributed ledger network, a hash of the spectrum allocation, where the spectrum allocation enables the radio access network of the spectrum renter to provide radio access services to wireless network devices.

Spectrum allocation using a distributed ledger network

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

Network architecture, methods, and devices for a wireless communications network

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

A network node of a communications network configured to provide Citizen Broadband Radio Service (CBRS) to at least one end user device (EUD) in a coverage area of the network node. The network node comprises: at least one processor; and a memory storing software instructions configured to control at least one processor to perform steps of: detecting interference from at least one aggressor device in the network; and reporting the detected interference to at least one of a Spectrum Access System (SAS) and a co-existence manager (CxM) of the communications network.

A transmitter and a method therein for transmitting discovery signals to a receiver. The transmitter and the receiver are comprised in a radio communications system. The transmitter transmits two or more discovery signals over two or more directions. Each discovery signal is configured to span over a fraction of a carrier bandwidth.

Transmitter for transmitting discovery signals, a receiver and methods therein

Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

Beam-scan time indicator

In a mobile network, the transmission of downlink data blocks to one or more terminal devices is accomplished on the basis of a retransmission protocol with a first feedback time defining a time interval between transmission of a first data block and transmission of a first feedback message being different from a second feedback time defining a time interval between transmission of a second data block and transmission of a second feedback message. The first feedback message indicates whether the first data block was successfully received, and the second feedback message indicates whether the second data block was successfully received. A base station of the mobile network controls the terminal device to send the second feedback message on other resources than used for transmission of the first feedback message.

Retransmission protocol feedback handling with multiple feedback times

Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices () in a cellular communications network () depending on mode of operation. In one embodiment, a node () in the cellular communications network () determines whether a wireless device () (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node () then applies different values for at least one parameter depending on whether the wireless device () is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing so, signaling overhead and energy consumption within the wireless device () when operating in the long range extension mode is substantially reduced.

Method for modifying parameter values for long range extension and corresponding node

There is provided a method in a first network node (e.g. CBSD) for negotiating AAS antenna pattern and for radio planning. The method comprises: determining () one or more cell shaping parameters; sending () the determined cell shaping parameters to a second network node (e.g. SAS or CxM); receiving () an allocation of resources based on the determined cell shaping parameters. Another method is disclosed as well and may comprise: receiving () an envelope of radio frequency power for maximizing a coverage area, from a second network node (e.g. SAS); determining () a beam pattern based on the received envelope; sending () the determined beam pattern to the second node.
