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, e.g., if the data is corrupted, select one or more model to recover the data and/or determine whether reception is successful, e.g., from a semantic point of view. The proposed system may support higher data rates, less retransmissions, and/or better quality of user experience.

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: Systems and methods for radio protocol architectures in cell-free networks are disclosed herein. One or more base stations make up a cell-free cluster that serves a user equipment (UE). A clustering control function (CCF) may establish, for a radio bearer that communicates data between the cluster and the UE, one or more sub-clusters of the one or more base stations. Each sub-cluster corresponds to a unique RLC entity within the protocol stack for the radio bearer in question. The CCF communicates with the base stations of the cluster and the UE to establish this sub-clustering arrangement. Details of this messaging are described herein. Data of the radio bearer is then transmitted between the cluster and the UE according to the established sub-clusters/RLC entities. For example, the network may transport either the same data of the radio bearer and/or unique data of the radio bearer through any/each of the sub-clusters/RLC entities.

Abstract: Systems and methods for clustering in cell-free networks are described herein. A cluster of one or more base stations provides radio access network (RAN) functionality to a user equipment (UE) within the wireless communication system in a cell-free manner (e.g., without using a base-station-centric cell context, as in prior wireless communication systems). A cluster that is serving a UE comprises one or more connected base stations (cBSs) that actively serve the UE. A clustering control function (CCF) of the network establishes and maintains the cluster that is serving one or more UEs. Herein, messaging systems and messaging types used by the CCF, base station(s), and UE(s) within this cell-free context are discussed. Initial clustering methods used by a CCF to form a cluster for a UE are discussed. Further, clustering update methods used by a CCF to maintain/modify a cluster for a UE are discussed.

Abstract: A communication system may include a base station (BS), a user equipment (UE) device, a reconfigurable intelligent surface (RIS) having a local controller, and a remote controller. Antenna elements on the RIS may reflect signals between the BS and UE while exhibiting reflection coefficients. The remote controller may transmit a control model and the UE may transmit local information to the local controller, which generates the reflection coefficients based on the local information and control model. Alternatively, the remote controller may transmit the control model to the UE and a codebook to the RIS. The UE may transmit an identifier to the RIS based on local information and the control model. The local controller may implement reflection coefficients of a codebook entry identified by the identifier. Splitting control of the RIS in these ways may minimize communication overhead, provide coverage extension for the UE, and optimize privacy.

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.
