There is provided a method, computer program and apparatus for causing an apparatus to perform: determining that a first non-terrestrial apparatus coverage area provided by a non-terrestrial apparatus will at least partially overlap with a first access coverage area provided by a terrestrial access network node at and/or during a first time; determining a first Doppler shift correction value, the first Doppler shift correction value corresponding to a frequency shift resulting from a relative velocity difference between the non-terrestrial apparatus and the terrestrial access network node at and/or during the first time; determining at least one first shifted non-terrestrial apparatus frequency by correcting at least one transmission and/or reception frequency of the non-terrestrial apparatus using the first Doppler shift correction value; and causing the terrestrial access network node to abstain from transmitting and/or receiving signalling on resources corresponding to the at least one first shifted non-terrestrial apparatus frequency.

Apparatus, method, and computer program

A method in a network node is disclosed. The method comprises receiving channel state information from a user equipment, the channel state information comprising a first transmission rank reported by the user equipment for downlink transmission of a packet. The method further comprises determining whether the packet is a signaling bearer packet or a data bearer packet, and upon determining that the packet is a signaling bearer packet, modifying the first transmission rank to a second transmission rank, the second transmission rank comprising a lower rank than the first transmission rank reported by the user equipment.

Method to transmit signaling radio bearer messages in multi antenna wireless communication system

An access node (e.g., Node B), a control node (e.g., RNC) and various methods are described herein for adapting a reporting period for a user equipment, wherein the reporting period indicates how often the user equipment is to send a feedback message containing a channel quality indicator (CQI) to the access node (e.g., Node B).
