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.

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

Methods performed by a wireless device operating in a dormant mode comprise performing a measurement on each of a plurality of resources from a predetermined set of resources or demodulating and decoding information from each of a plurality of resources from a predetermined set of resources, such as a set of beams. The methods further include evaluating the measurement or the demodulated and decoded information for each of the plurality of resources against a predetermined criterion, and then discontinuing the performing and evaluating of measurements, or discontinuing the demodulating and decoding and evaluation of information, in response to determining that the predetermined criterion is met, such that one or more resources in the predetermined set of resources are neither measured nor demodulated and decoded. The methods further comprise deactivating receiver circuitry, further in response to determining that the predetermined criterion is met.

Dormant mode measurement optimization

In an aspect, a wireless device with a plurality of transmitter chains that can be selectively used to transmit a beam-formed signal determines a targeted receive power for the beam-formed signal, with respect to a target receiving device. The wireless device selects a number of the plurality of transmitter chains for forming the beam-formed signal, based on the targeted receive power and based on an estimated power consumption for each of the plurality of transmitter chains. The selection is performed so as to minimize a total power consumption, given the estimated power consumptions. The wireless device transmits a beam-formed signal, using the selected number of the plurality of transmitter chains.

Procedures to control beamforming

A UE and a method performed by the UE for power control of uplink transmissions, when the UE is connected in dual connectivity mode to at least a first network node and a second network node are provided. The method includes determining to perform a first uplink transmission to the first network node and a second uplink transmission to the second network node, the uplink transmissions to be performed simultaneously. The method also includes determining a respective first and second uplink transmission power for the first and second uplink transmission; and transmitting the first and the second uplink transmissions at the first and the second uplink transmission power respectively when the sum of the first and second uplink transmission power is below a maximum transmission power.

User equipment and a method for power control of uplink transmissions

Methods and apparatuses exemplified in this disclosure provide mechanisms for a wireless communication device to indicate its Radio Access Technology (RAT) preferences to a wireless communication network, and for a wireless communication network to consider the RAT preferences of a given device when deciding which RAT the device will use. As a non-limiting example of the advantages flowing from these mechanisms, devices operating within a network that includes or is associated with multiple RATs can indicate their preferences for which RAT they use, while still allowing the network to retain control of the RAT selection decisions. Such flexibility offers significant advantages in 5G networks that provide tight integration between multiple RATS&#x2014;e.g., between LTE and NR air interfaces. However, the methods and apparatuses disclosed herein are not limited to 5G networks.

Method and apparatus for indicating and using radio access technology preferences in a wireless communication network

A method and device for transmitting information in a telecommunication system are described. A device (UE) selects which one of two or more radio access technologies (RATs) or, which one of two or more frequency bands, to use for transmission of a data signal. The device transmits the data signal using the selected RAT or frequency band.

Methods and systems for autonomous device selection of transmission resources

Embodiments herein relate to a method performed by a wireless device for managing communication of the wireless device in a wireless communications network. The wireless device determines at least two waveform parameters based on a metric of the wireless device, for communicating data between the wireless device and a radio network node in the wireless communications network. The wireless device further transmits an indication indicating the at least two determined waveform parameters to the radio network node.
