US 2023/0412242 A1 · USER EQUIPMENT COMPRISING MULTIPLE ANTENNAS

Abstract

User equipment (UE) may be provided that includes means for: reporting at least one candidate CSI beam index to a network to avoid and/or mitigate a maximum permissible exposure (MPE) event; wherein the user equipment associates at least one candidate antenna of the user equipment to the at least one candidate CSI beam index. An apparatus may also be provided that includes means for: creating a first mapping of antennas to downlink path delay intervals using a wider beam downlink reference signal; creating a second mapping of downlink path delay intervals to downlink spatial filters using different narrower beam reference signals; and controlling the selection of an antenna based on second mapping.

User equipment 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 perform:
reporting at least one candidate channel state index beam index to a network to avoid and/or mitigate a maximum permissible exposure event;
wherein the user equipment associates at least one candidate antenna of the user equipment to the at least one candidate channel state index beam index.
