Abstract: An arrangement for switching beams in wireless communications is based on determining an exact timing for switching from one beam to another. The determined exact timing is communicated to a user equipment requiring a beam switch. The user equipment receives the determined exact timing and is capable of switching beams in synchronicity with the base station.

Abstract: Apparatus and method for communication in non-terrestrial networks are disclosed. A set of Doppler shift curves for different distances to one or more satellite orbits is obtained. Measurements of satellite transmission are performed to obtain estimate of instantaneous Doppler shift of the transmission, the measurements including a timestamp. A Doppler shift curve corresponding to the measurements is calculated. A time offset on the selected curve is determined utilising the timestamps of the measurements, the time offset indicating the position of the Doppler shift of the apparatus on the curve. The Doppler shift of the satellite transmission is determined utilising the selected curve and the time offset.

Abstract: A technique of performing a RACK procedure includes a framework for a two-step RACK in which a first message (MsgA) from the UE to the gNB has data carrying resources (i.e., PUSCH) is organized into a time-frequency array defined by a mapping to a plurality of preambles. Such a two-step RACK has less latency than the four-step RACK due to fewer signaling exchanges. Moreover, this two-step RACK also causes the UE to use less power due to a decreased signaling overhead.

Abstract: In accordance with an example embodiment of the present invention, a method comprising: receiving, by a user equipment, instructions based on a determination that a communication sent from the user equipment to at least one network comprising signaling to at least one network node over continuous time slots of at least one uplink connection would cause a problem with the communication; and based on the instructions, preventing by the user equipment the signaling over at least one particular time slot of the at least one uplink connection to overcome the problem, wherein the instructions are received in a recurring pattern indicating the at least one particular time slot.

Abstract: It is provided a method, comprising obtaining at least one of a first duty cycle level and a first reception ratio of a terminal using a first band for transmission; deciding whether or not the first band is allowed to be allocated to the terminal based on a predetermined first duty cycle restriction of the first band and the at least one of the first duty cycle level and the first reception ratio; inhibiting allocating the first band to the terminal if the first band is not allowed to be allocated to the terminal.

Abstract: A method is provided including configuring, by a network node, a set of resources to be used by at least one user equipment for transmitting a first type of uplink data; receiving from the at least one user equipment information that indicates that at least one resource in the set of resources comprises a second type of uplink data different than the first type of uplink data; and decoding data received on the at least one resource based on the information.

Abstract: Fallback aspects associated with the power ramping procedure are addressed. More specifically, a set of control mechanisms allows for a gNB to adjust thresholds for controlling the UE transfer from a 2-step RACH procedure to a 4-step RACH procedure while still maintaining a proper setting for transmit power during this transition. The mechanism will allow for a UE to have a smooth transition to the 4-step procedure instead of having to start the power ramping from scratch when transferring to the fall-back routine.

Abstract: Example embodiments of the present disclosure relate to information transmission in random access. A method comprises selecting, one of a plurality of random access preambles that is received from a terminal device, the plurality of random access preambles being divided into a plurality of subsets of random access preambles; selecting at least one predefined sequence associated with the selected random access preamble based on a predetermined association between a plurality of predefined sequences and the plurality of subsets of random access preambles and based on a target resource unit to be used for transmission of control information and data information; modulating the control information with one of the at least one predefined sequence, the control information indicating configuration of the data information; and transmitting the selected random access preamble, the modulated control information, and the data information in a random access message to the network device.
