摘要： A method and network node having integrated access and backhaul (IAB) functionality are disclosed. According to one aspect, a network node determines information concerning at least one of: (i) an impairment of a first signal from a first integrated access backhaul node that is caused by a second signal from a second IAB node and (ii) an impairment of the second signal that is caused by the first signal. The network node further selects a multiplexing capability for the network node based at least in part on the determined information concerning at least one of the impairments and further multiplexes signals for the first and second IAB nodes using the selected multiplexing capability.

摘要： Configuring each of two signals having a frequency bandwidth which is less than a system frequency bandwidth available to the network node for wireless transmissions. The method includes allocating a first signal of the two signals on a first time and frequency resource based on a configuration in which the first signal is included, allocating a second signal of the two signals on a second time and frequency resource based on the configuration, wherein frequency use of the second time and frequency resource is at least partly different from frequency use of the first time and frequency resource, and providing signalling for a wireless communication device enabling the wireless communication device to derive the first and second time and frequency resources. Allocating the first and second signals includes allocating another time and frequency resource adjacent in time or frequency to at least one of the first and the second signals.

摘要： A beamforming selection method of a first wireless communication node is disclosed. The method includes receiving first reference signaling, transmitted from a second wireless communication node using a first beamforming setting, generating a first channel estimate based on the first reference signaling, and transmitting, using a second beamforming setting, second reference signaling for reception by the second wireless communication node, wherein each coefficient of the second beamforming setting represents a complex conjugate of a corresponding component of the first channel estimate.
In some embodiments, the method further includes iterating the receiving, generating, and transmitting steps until a stopping criterion is met.
For example, the stopping criterion may include that a number of iterations performed equals a maximum number of iterations, and/or that a beamforming convergence criterion is met. Corresponding apparatus, wireless communication node and computer program product are also disclosed.-

摘要： There is provided a reflection node for handling link failure towards a network node. The reflection node includes a controller for controlling a passive meta-surface having a controllable reflection angle for reflecting radio waves over a communication channel between a network node and a wireless device. The reflection node includes a transceiver unit for receiving instructions from the network node over a control channel. The transceiver unit is configured to determine a link failure event on the control channel between the reflection node and the network node. The controller is configured to, during the link failure event, control the reflection angle of the passive meta-surface using reflection settings specified by configuration data for reflecting the radio waves over the communication channel.

摘要： A network node is arranged to operate in a cell of a cellular communication system. The network node comprises an interface towards the cellular communication system where the interface is arranged to receive paging information for an idle user equipment, UE, a paging handler arranged to determine a mode of power saving for the UE, and to determine timing for a wake-up signal based on the determined mode and the received paging information, and a transmitter arranged to transmit the wake-up signal at the determined timing. A method of the network node comprises receiving paging information for an idle user equipment, UE, from the cellular communication system, determining a mode of power saving for the UE, determining timing for a wake-up signal based on the determined mode and the received paging information, and transmitting the wake-up signal at the determined timing.

摘要： Wake-up signal grouping is based on a paging probability (PP) type rather than a service type to further reduce false paging. This approach enables differentiation between wireless devices with the same service type. Paging probability can be expressed as a function of the wireless devices' traffic profile, DRX, eDRX, or power saving mode (PSM) configuration, paging configuration (number of narrowbands, paging carriers, nB parameter, etc.), and other parameters.
