Abstract
Updates to the existing Random Access Channel (RACH) procedure and updates to messages used in the RACH procedure may be shown to allow a base station, or another network element, determine whether communication with a user equipment (UE) are to be carried out with or without help from one or more Reconfigurable Intelligent Surfaces (RIS).
Claims18
A method comprising:
- transmitting, to a Reconfigurable Intelligent Surface (RIS), instructions specifying:
- a first mode for implementing in a first resource;
- and
- a second mode for implementing in a second resource;
- transmitting, to a device, outbound messages, the outbound messages including:
- in the first resource, a first outbound message;
- and
- in the second resource, a second outbound message;
- and
- receiving an inbound message, the inbound message including an indication indicating that one or more of the first outbound message and the second outbound message has been received at the device;
- and
- determining, based on the device having received one or more of the first outbound message or the second outbound message, whether communication with the device occurs via the RIS.

An apparatus comprising:
- a memory storing instructions;
- and
- at least one processor caused, by executing the instructions, to:
- transmit, to a Reconfigurable Intelligent Surface (RIS), instructions specifying:
- a first mode for implementing in a first resource;
- and
- a second mode for implementing in a second resource;
- transmit, to a device, outbound messages, the outbound messages including:
- in the first resource, a first outbound message;
- and
- in the second resource, a second outbound message;
- and
- receive an inbound message, the inbound message including an indication indicating that one or more of the first outbound message and the second outbound message has been received at the device;
- and
- determine, based on the device having received one or more of the first outbound message and the second outbound message, whether communication with the device occurs via the RIS.
12 more elements
A method comprising:
- receiving, from a network element, one or more inbound messages;
- transmitting, to the network element, an outbound message, the outbound message including an indication indicating that the one or more inbound messages have been received;
- and
- receiving, from the network element, a further inbound message, the further inbound message including an indication indicating that communication with the network element occurs via a Reconfigurable Intelligent Surface.
1 more element
An apparatus comprising:
- a memory storing instructions;
- and
- at least one processor caused, by executing the instructions, to:
- receive, from a network element, one or more inbound messages;
- transmit, to the network element, an outbound message, the outbound message including an indication indicating that the one or more inbound messages have been received;
- and
- receive, from the network element, a further inbound message, the further inbound message including an indication indicating that communication with the network element occurs via a Reconfigurable Intelligent Surface.
