Power efficient communication with wireless smart repeater

A smart repeater (SMR), comprising:

• a memory;
• and
• a processing circuitry configured to, when executing instructions stored in the memory, cause the SMR to:
• receive control information to manage power efficiency of a communication with a base station or a user equipment (UE), wherein the control information is received using a first beam and comprises an aggregation of different DCI bandwidth indicator fields of a plurality of SMRs that enable bandwidth adaptation among the plurality of SMRs, and at least one of:
• a component carrier (CC) index, a bandwidth part (BWP) identifier (ID), or a set of parameters to configure on-off operations of one or more bandwidths;
• configure, based on the control information, a power control mechanism for transmission of the communication, wherein the power control mechanism includes bandwidth adaptation comprising transmission of the communication using a second beam that is narrower than the first beam;
• and
• perform the communication with the base station or the UE using the second beam.
