Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: a method for distributed coordination between L2 nodes. In one aspect, the method can include actions of detecting, by a first L2-node, an occurrence of a triggering condition, determining, by the first L2-node, a plurality of message recipients, wherein each message recipient of the plurality of recipients is another L2-node, determining, by the first L2-node, a message type based on (i) the detected occurrence of the triggering condition and (ii) the determined plurality of message recipients, and transmitting, by the first L2-node, a message of the determined message type to each of the plurality of message recipients.

Abstract: Methods and systems for semantic encoding by a user equipment (UE) are configured for determining an expected power consumption for encoding video data that includes semantic features, the semantic features representing a meaning of information represented in video frames of the video data; encoding one or more video frames of the video data using a selected a semantic representation of one or more video frames of the video data, the semantic representation being selected based on the expected power consumption that is determined; and transmitting the encoded video data including the semantic representation.

Abstract: A system may include an access point (AP), user equipment (UE), and a reconfigurable intelligent surface (RIS). The RIS may include an array of elements coupled to adjustable devices controlled to cause the array to reflect signals in different directions. The RIS may be controlled in a first mode in which the AP controls the adjustable devices, a second mode in which the UE controls the adjustable devices, and a third mode in which the RIS controls the adjustable devices. The RIS, AP, or UE may determine which mode to place the RIS in based on a downlink signal transmitted by the AP, an uplink signal transmitted by the UE, measurements of the signals performed on the RIS, a first distance or round trip time between the AP and the RIS, and/or a second distance or round trip time between the UE and the RIS.

The processor is configured to determine a direction of transmission for a non-orthogonal multiple access (NOMA) transmission; determine a set of resources to be used for the NOMA transmission; determine a forward error correction (FEC) coding scheme to be used for the NOMA transmission; determine, using a codebook, a joint modulation scheme to be used for the NOMA transmission; and transmit or receive the NOMA transmission on the set of resources, in accord with the direction of transmission, the FEC coding scheme, and the joint modulation scheme.

Abstract: A communication system may include an access point (AP), user equipment (UE) device, and reconfigurable intelligent surface (RIS). The UE may control the RIS by transmitting control signals that configure antenna elements on the RIS. The RIS may reflect wireless signals between the UE and the AP. The RIS may be known to the network. The UE may transmit a report to the AP that includes information about the RIS. The UE may receive assistance information from the AP. The UE may control the RIS based at least in part on the assistance information. The UE may transmit measurement reports to the AP. The AP may update its signal beams based on the information about the RIS and the measurement reports. Providing the network with awareness of the RIS may serve to optimize the wireless performance of the UE device and/or the network.

Abstract: Methods, systems, and apparatuses are presented for utilizing a narrowband assisting network (NBAN) and a positioning assisting network (PAN) to assist in establishing and managing communications on a THz band wireless communication network. The THz network may be capable of transmitting/receiving with high bandwidth, but may be resource intensive and may be constrained to line-of-sight (LoS) communications. The NBAN and PAN may help to minimize the resources consumed by the THz network. The NBAN may identify a set of nodes of the THz network as candidates for establishing a connection with a user equipment (UE). The PAN may determine a position of each candidate relative to the UE, and may communicate the position to the respective candidate and to the UE, which may use the position information to expedite a beam alignment procedure. The NBAN may provide scheduling and other control signaling for the THz network.

Abstract: This disclosure relates to techniques for performing communication in a wireless communication system. The communication may be semantic communication and/or may use a programmable protocol stack. A protocol stack at a transmitter and/or receiver may include customization from an application platform, e.g., which may replace one or more layers relative to a non-customized protocol stack. A transmitter may transmit data, via the customized protocol stack, using a best effort data channel, e.g., with transmission characteristics that are relatively lossy in comparison to a data channel used by the non-customized protocol stack. A receiver may receive the data and may determine whether reception is successful, e.g., from a semantic point of view. A media access control layer may interact with both the customized and non-customized stacks. The proposed system may support higher data rates, less retransmissions, and/or better quality of user experience.

Abstract: A user equipment (UE) device may communicate with a base station using signals reflected off a network-independent intelligent reflecting surface (IRS). The UE device and the IRS may form part of a virtual UE device, the components of which communicate with each other and with other virtual UE devices over a channel control plane (CCP) separate from the control and data plane of the base station. The CCP may be used to perform control functions for the virtual UE device such as channel estimation, synchronization, scheduling, sensing, and beamforming. The IRS may be controlled by the UE device, a service controller, or itself. Grouping the UE device and IRS into a virtual UE device may keep the structure the presence of the IRS transparent to the network while allowing the UE device to have more beneficial channel propagation properties relative to when the IRS is registered to the network.
