Wideband ue power saving by switching wideband data to narrowband data with wideband reference signal

A network device, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on stored information that is stored in the at least one memory, the at least one processor, individually or in any combination, is configured to:
• receive, from a wireless device, a first indication to switch from a first mode of operation associated with a first data bandwidth and a first reference signal bandwidth to a second mode of operation associated with a second data bandwidth and a second reference signal bandwidth, wherein at least one of:
• the second data bandwidth is smaller than the first data bandwidth and the second reference signal bandwidth is larger than the second data bandwidth;
• the first data bandwidth is smaller than the first reference signal bandwidth and the second data bandwidth is smaller than the second reference signal bandwidth;
• or
• the first data bandwidth is smaller than the second data bandwidth and the first reference signal bandwidth is larger than the first data bandwidth;
• and
• transmit, for the wireless device, a data signal via the second data bandwidth and a reference signal via the second reference signal bandwidth.

A method of wireless communication at a wireless device, comprising:

• detecting a first trigger condition at the wireless device;
• and

• the second data bandwidth is smaller than the first data bandwidth and the second reference signal bandwidth is larger than the second data bandwidth;
• the first data bandwidth is smaller than the first reference signal bandwidth and the second data bandwidth is smaller than the second reference signal bandwidth;
• or
• the first data bandwidth is smaller than the second data bandwidth and the first reference signal bandwidth is larger than the first data bandwidth.
