Abstract: Frequency domain compression of fronthaul interface for transporting frequency domain data over Ethernet includes applying Inverse Discrete Fourier Transform to frequency domain data contained in a frequency bandwidth to generate a time domain output signal in a time domain. The time domain output signal is compressed to generate a compressed time domain output signal. The compressed time domain output signal is transmitted over a fronthaul interface to a remote unit. The compressed time domain output signal is decompressable at the remote unit to generate a decompressed time domain output signal. Discreet Fourier Transform is applied to the decompressed time domain output signal at the remote unit to recover the frequency domain data.

Abstract: An apparatus may be configured to: receive information comprising at least: an indication of a first PRACH configuration, wherein the first PRACH configuration is associated with an identifier of at least one first radio beam, and an indication of a second PRACH configuration, at least partially different from the first PRACH configuration, wherein the second PRACH configuration is associated with an identifier of at least one second radio beam, wherein the at least one second radio beam comprises, at least, a radio beam for communicating with a network node via a repeater; select a radio beam; select a PRACH configuration based, at least partially, on the received information; and transmit, to the network node, a radio access preamble on the selected radio beam according to the selected PRACH configuration.

Abstract: Techniques for providing a multiple donor supported repeater within a communication network are disclosed. An example of such techniques includes an apparatus which establishes a control channel with a respective donor node of one or more donor nodes. The apparatus receives an indication of resource information from the one or more donor nodes via the corresponding control channel. The apparatus determines a grid of physical repeater beam channels to cover an access area based at least in part on the received indication of resource information from the one or more donor nodes. Corresponding methods and computer program products are also provided.

Abstract: Techniques of relaying signals include modifying an IAB node to have a built-in mode to support signal repetition, wherein a portion of the time-frequency resources of the IAB are dynamically allocated in the repeater mode for delay-sensitive data.

Abstract: There is disclosed a method including at a serving cell, using cell measurements performed at a neighbouring cell to assist the serving cell in determining whether a serving cell user equipment which supports skip-uplink is in a discontinuous transmission state. The cell measurements performed at the neighbouring cell include measurements of the serving cell user equipment.
