Scheduling for devices with limited signal processing capability

A method of a wireless communication device adapted to communicate with a network node of a cellular communication system, the method comprising:

• transmitting information indicative of a signal processing capability of the wireless communication device;
• receiving, from the network node, a scheduling of one or more first time-frequency resources of a first reception occasion, wherein the first reception occasion is comprised in a first occasion of communication between the network node and the wireless communication device;
• receiving data from the network node during the first reception occasion in the scheduled one or more first time-frequency resources;
• determining a length of a time interval between the first and a second occasion of communication between the network node and the wireless communication device;
• and
• performing an operation of communication between the network node and the wireless communication device during the second occasion of communication;
• wherein, if the signal processing capability does not fulfill a signal processing capability requirement, the length of the time interval is determined such that a first length is selected if the scheduled one or more first time-frequency resources have a first frequency span and a second length is selected if the scheduled one or more first time-frequency resources have a second frequency span, where the first length exceeds the second length and the first frequency span exceeds the second frequency span.

• acquiring a signal processing capability of the wireless communication device;
• scheduling, based on the acquired signal processing capability, one or more first time-frequency resources of a first transmission occasion for transmission to the wireless communication device, wherein the first transmission occasion is comprised in a first occasion of communication between the network node and the wireless communication device:
• determining, based on the acquired signal processing capability, a length of a time interval between the first and a second occasion of communication between the network node and the wireless communication device;
• transmitting data to the wireless communication device during the first transmission occasion using the scheduled one or more first time-frequency resources;
• and
• performing an operation of communication between the network node and the wireless communication device during the second occasion of communication;
• wherein, if the acquired signal processing capability does not fulfill a signal processing capability requirement, the length of the time interval is determined such that a first length is selected if the scheduled one or more first time-frequency resources have a first frequency span and a second length is selected if the scheduled one or more first time-frequency resources have a second frequency span, where the first length exceeds the second length and the first frequency span exceeds the second frequency span.
