Abstract: An L1 setup procedure is provided that can be used in place of RRC setup. The new L1 setup can achieve the same functionality as the current RRC setup, but setup data is exchanged between a BS and UE only in L1. This setup data can include for example, parameters for radio bearer configuration and parameters for master cell group configuration, cell selection configuration, cell reselection configuration, or measurement configuration. A two stage DCI, together with a scheduled physical downlink shared channel (PDSCH) resource may be used for L1 setup, in which the second stage of the two stage DCI indicates that the scheduled PDSCH resource contains L1 data for L1 setup.

Abstract: Current online training procedures for artificial intelligence/machine learning (AI/ML) models for wireless communication generally suffer from high communication overhead and/or significant delays in training, particularly when training data is exchanged over an unreliable/hostile communication channel. An example method includes communicating, in accordance with a first communication mode, data or control information with a second device in the wireless communication network. The first communication mode is one of a plurality of communication modes comprising at least the first communication mode and a second communication mode, the second communication mode differing from the first communication mode in terms of at least one of a quantization level used to quantize values of variables in the data or control information, or a Hybrid Automatic Repeat reQuest (HARQ) feedback and retransmission mode for selective retransmission of one or more portions of the data or control information.

Abstract: Embodiments of this application provide a communication method, a communications apparatus, and a communications system, to determine a physical resource block (PRB) grid when a center frequency of a synchronization signal (SS) is inconsistent with a center frequency of a carrier. The method includes: receiving, by a terminal, an SS from a network device; determining, by the terminal, a first PRB grid based on the SS; receiving, by the terminal, first indication information from the network device, where the first indication information is used to indicate a first frequency offset between the first PRB grid and a second PRB grid; and determining, by the terminal, the second PRB grid based on the first PRB grid and the first frequency offset.

Abstract: This application discloses a communication method that includes: receiving first control information of a first bandwidth part (BWP) and second control information of a second BWP, and receiving a first data channel and a second data channel based on the first control information. The first BWP includes a first frequency domain resource and a second frequency domain resource. The second BWP includes a third frequency domain resource, and the third frequency domain resource and the second frequency domain resource overlap. The first data channel is located on the first frequency domain resource, and the second data channel is located on the third frequency domain resource. The foregoing method provides a manner of transmitting data on the first and second BWPs that partially overlap.

Abstract: In some wireless communication systems, user equipments (UEs) wirelessly communicate with a radio access network (RAN) via one or more transmit-and-receive points (TRPs). A user of a UE is provided with a mobile connection by a network operator. Different network operators may share the same RAN infrastructure. For example, two UEs may be in a same shared RAN and communicate with a same TRP. Sometimes a same UE may transmit/receive traffic associated with multiple different services, however, the traffic for each service is independently scheduled. Some embodiments herein are directed to reductions in overhead for scenarios in which a same UE transmits/receives traffic associated with multiple different services. Some embodiments relate to a new DCI format for scheduling traffic associated with one or multiple services. Some embodiments relate to implementing common paging resources for a UE to receive a paging message associated with one or multiple services.
