8 Claims

1. A method, comprising,

camping, by a wireless device, on a first initial bandwidth part among initial bandwidth parts;

receiving, by the wireless device, bandwidth information for a broadcast-multicast service;

determining, by the wireless device, that a connection to receive the broadcast-multicast service is not required, based on the bandwidth information informing that the broadcast-multicast service is provided on a second initial bandwidth part, which is different the first initial bandwidth part, among the initial bandwidth parts;

prioritizing, by the wireless device, a frequency corresponding to the second initial bandwidth part;

moving, by the wireless device, to the second initial bandwidth part based on the prioritization; and

receiving, by the wireless device, the broadcast-multicast service via the second initial bandwidth part.
