Multicast system, method, and apparatus

A method performed by a wireless device operating in a wireless communications network, wherein the wireless communications network comprises a first group of wireless devices supporting transmission with a first bandwidth under a threshold and a second group of wireless devices supporting transmission with a second bandwidth over the threshold, and wherein the wireless device is comprised in the first group of wireless devices, the method comprising:

• receiving a first configuration from a first network node operating in the wireless communications network, the wireless device having a first set of time-frequency resources to carry a first type of information between a second network node operating in the wireless communications network and the wireless device, and the first configuration configuring the wireless device with:
• at least one second set of time-frequency resources to carry a second type of information between the second network node and the wireless device,
• wherein the second type of information is to be transmitted simultaneously to the first group of wireless devices, and wherein the first type of information is to be transmitted to at least one of:
• i) the first group of wireless devices and the second group of wireless devices, and ii) the wireless device, and
• wherein the first set of time-frequency resources and the at least one second set of time-frequency resources are in at least one of:
• (a) different sets of frequencies and (b) different transmission time periods, and have different coverages, wherein transmission of the second type of information is enabled to reach the first group of wireless devices supporting transmission with the first bandwidth under the threshold.

A first network node configured to operate in a wireless communications network, wherein the wireless communications network comprises a first group of wireless devices configured to support transmission with a first bandwidth under a threshold and a second group of wireless devices configured to support transmission with a second bandwidth over the threshold, the first network node being further configured to:

• configure a wireless device comprised in the first group of wireless devices, the wireless device being configured to have a first set of time-frequency resources to carry a first type of information between a second network node configured to operate in the wireless communications network and the wireless device, with:
• at least one second set of time-frequency resources to carry a second type of information between the second network node and the wireless device,
• wherein the second type of information is configured to be transmitted simultaneously to the first group of wireless devices, and wherein the first type of information is configured to be transmitted to at least one of:
• i) the first group of wireless devices and the second group of wireless devices, and ii) the wireless device, and
• wherein the first set of time-frequency resources and the at least one second set of time-frequency resources are configured to be in at least one of:
• (a) different sets of frequencies and (b) different transmission time periods, and have different coverages, wherein transmission of the second type of information is enabled to reach the first group of wireless devices supporting transmission with a first bandwidth under a threshold.
