Wireless resource allocation

Abstract

According to an example aspect of the present invention, there is provided an apparatus comprising at least one processing core and at least one memory storing instructions that, when executed by the at least one processing core, cause the apparatus at least to transmit in uplink or sidelink, or receive in downlink, using orthogonal frequency-division multiplexing, via a physical shared channel in a system comprising resource block groups, each resource block group comprising two or more resource blocks, each resource block comprising plural subcarriers which are consecutive to each other in frequency, and process an allocation of resources for the physical shared channel, the allocation received from a network node, the allocation defining that the apparatus may use a part of, but not all, subcarriers of each one of one or more resource blocks for communication via the physical shared channel.
