Abstract
According to an example aspect of the present disclosure, there is provided a method comprising receiving a message at a user equipment (UE) from a base station (BS) the message including a constraint threshold, receiving a message at the UE from the BS the message including a fallback beam reporting mode, performing by the UE downlink (DL) reference signal (RS) measurements, determining by the UE a difference between DL RS measurements, and in response to determining the difference between DL RS measurements is not less than the constraint threshold switch to the fallback beam reporting mode.

1-168. (canceled)
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- receive a message at a user equipment (UE), from a base station (BS), the message including a constraint threshold;
- receive a message at the UE, from the BS, the message including a fallback beam reporting mode;
- perform, by the UE, downlink (DL) reference signal (RS) measurements;
- determine, by the UE, a difference between DL RS measurements;
- and
- in response to determining the difference between DL RS measurements is not less than the constraint threshold, switch to the fallback beam reporting mode.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- communicate a message from a base station (BS) to a user equipment, the message including a constraint threshold;
- communicate a message from the BS to the UE, the message including a fallback beam reporting mode;
- receive a message at the BS, from the UE, the message including N best downlink (DL) reference signal (RS) measurements associated with the UE;
- and
- determine, by the BS, a group-based beam reporting mode based on the DL RS measurements.
