Abstract
Certain aspects of the present disclosure provide techniques for wireless communication by a network entity. For example, the network entity defines a size of reconfigurable intelligent surface (RIS) elements. The network entity further defines a set of patterns representing active RIS elements and/or inactive RIS elements, based on the size of RIS elements. The network entity transmits an indication of the size of RIS elements and the set of patterns to a RIS controller.
Claims24
An apparatus for wireless communication by a network entity, comprising:
- at least one processor and a memory configured to:
- define a size of reconfigurable intelligent surface (RIS) elements;
- define a set of patterns, via a radio resource control (RRC) configuration, representing one or more active RIS elements or one or more inactive RIS elements, based on the size of the RIS elements;
- transmit, to a RIS controller, an indication of the size of the RIS elements and the set of patterns;
- and
- transmit, to the RIS controller, via a medium access control (MAC) control element (CE), an indication of a subset of the set of patterns.
An apparatus for wireless communication by a network entity, comprising:
- at least one processor and a memory configured to:
- define a set of bitmaps, each bitmap has a size of a number of reconfigurable intelligent surface (RIS) elements;
- and
- transmit, to a RIS controller, an indication of the set of bitmaps;
- and
- transmit, to the RIS controller, via a medium access control (MAC) control element (CE), an indication of a subset of the set of bitmaps.
An apparatus for wireless communication by a reconfigurable intelligent surface (RIS) controller, comprising:
- at least one processor and a memory configured to:
- define a size of reconfigurable intelligent surface (RIS) elements;
- transmit, to a network entity, an indication of the size of the RIS elements;
- receive, from the network entity, a set of patterns representing one or more active RIS elements or one or more inactive RIS elements, based on the size of the RIS elements;
- and
- receive, from the network entity, via a medium access control (MAC) control element (CE), an indication of a subset of the set of patterns.
