Abstract: Embodiments herein include a UE that receives one or more packets of a downlink packet set from a network node. The UE may identify a remaining delay budget and a remaining packet error budget for remaining packets of the downlink packet set based on Key Performance Indicator (KPI) requirements. The UE may perform a packet error prediction for the remaining packets, and perform a link adaptation operation based on the prediction and the remaining delay budget. A network node may perform similar actions on an uplink packet set.

Abstract: Described herein are solutions for dynamic sidelink (SL) autonomous channel selection access. A user equipment (UE) can initiate a sensing window based on a prediction of transport block (TB) generation. A SL-capable UE operating in mode 2 can predict an arrival of a TB in a buffer of the UE and can initiate monitoring of the channel for a configured duration before the predicted arrival of the TB. A sensing and selection window size can be adapted based on traffic quality of service (QoS). The UE can dynamically adapt the sensing and selection windows based on a predicted priority or QoS of the future TBs. These and many other features and examples are described herein.

Abstract: Apparatus and methods are provided for PDCP retransmission. A Tx PDCP entity generates a Tx request message including an ID of the Tx request message, Tx request configuration information, and one or more groups of PDUs. In response, a Tx UM RLC function determines one or more delivered PDUs and one or more non-delivered PDUs within a TTL period configured by the Tx request configuration information. The Tx UM RLC function generates a delivery Tx report based on the one or more delivered PDUs and the one or more non-delivered PDUs. The delivery Tx report is associated with the ID of the Tx request message. After expiration of a TTR period configured by the Tx request configuration information, the delivery Tx report is sent to the Tx PDCP entity. In response to the delivery Tx report, the Tx PDCP entity determines to retransmit the one or more non-delivered PDUs.

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: 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.
