Abstract: Methods for transmitting and receiving downlink control information (DCI) are provided along with corresponding network devices and apparatus. A first stage DCI is transmitted that explicitly indicates a scheduling information of a second stage DCI. The second stage DCI is transmitted in a first physical downlink shared channel (PDSCH), consistent with the scheduling information. The first PDSCH is a physical channel without data transmission. The receiving apparatus does not need to perform blind decoding of the second stage DCI because it is aware of its location from the scheduling information.

Abstract: Signaling resource overhead associated with current communication link adaptation mechanisms can be quite large and such mechanisms typically rely upon a channel state information (CSI) feedback process that can result in poor scheduling performance. Embodiments are disclosed in which a first device channel state information characterizing a wireless communication channel between the first device and a second device, and trains a machine learning (ML) module of the first device using the CSI as an ML module input and one or more modulation and coding scheme (MCS) parameters as an ML module output to satisfy a training target. By applying the concepts disclosed herein, overhead associated with feedback for MCS selection may be reduced compared to conventional link adaptation procedures, because, once ML modules at a pair of devices have been trained, the MCS selection by the ML modules can be done without requiring the ongoing feedback of CSI.

Abstract: Systems, methods, and apparatus on wireless network architecture and air interface are disclosed. In some embodiments, sensing agents communicate with user equipments (UEs) or nodes using one of multiple sensing modes through non-sensing-based or sensing-based links, and/or artificial intelligence (AI) agents communicate with UEs or nodes using one of multiple AI modes through non-AI-based or AI-based links. AI and sensing may work independently or together. For example, a sensing service request may be sent by an AI block to a sensing block to obtain sensing data from the sensing block, and the AI block may generate a configuration based on the sensing data. Various other features, related to example interfaces, channels, and other aspects of AI-enabled and/or sensing-enabled communications, for example, are also disclosed.

Abstract: Restrictions associated with the use of multiple carriers in long-term evolution (LTE) and/or new radio (NR) may impede implementing a flexible personalized spectrum for different user equipments (UEs). Apparatuses, devices, and methods are instead provided in which there is more flexible spectrum utilization, e.g. in which there may be fewer restrictions and more options for configuring carriers and/or bandwidth parts (BWPs) on a UE-specific basis. As one example, in some embodiments, there is not necessarily coupling between carriers, e.g. between uplink and downlink carriers. For example, an uplink carrier and a downlink carrier may be independently indicated so as to allow the uplink carrier and downlink carrier to be independently added, released, modified, activated, deactivated, and/or scheduled.

Abstract: One or more first transmit power control parameters that are common to transmit power control for multiple different physical uplink channels are transmitted by a network device and received by a user equipment (UE) in a wireless communication network. The UE transmits, and the network device receives, one of the multiple different physical uplink channels. That uplink channel is transmitted at a transmit power that is based on the first transmit power control parameter(s) and one or more second transmit power control parameters that are specific to the transmit power control for the uplink channel.

Abstract: A two-stage DCI framework is provided in which the first stage DCI is carried by PDCCH, second stage DCI is carried by PDSCH. The first stage DCI is blind decoded. The second stage DCI is indicated by the first stage DCI and therefor no blind decoding is necessary. The size of the second stage DCI can be very flexible, can indicate scheduling information for one carrier, multiple carriers, multi transmission for one carrier. The first stage DCI can be compact in size to enhance reliability.

Abstract: Systems, apparatuses and methods for providing flexible initial access processes in a wireless communication system are disclosed. These initial access processes may flexibly implement multiple frequency resources and/or multiple beams, which may improve spectrum utilization, improve load balance for a random access channel (RACH), reduce RACH collision and/or improve wireless coverage. According to one example method, an apparatus may receive, on a first downlink carrier and/or bandwidth part (carrier/BWP), a synchronization signal block (SSB) and first information. The first information indicates a plurality of RACH resources corresponding to a plurality of carriers/BWPs and/or to a plurality of beams. The apparatus may also transmit, on a first uplink carrier/BWP, a first message using a first RACH resource of the plurality of RACH resources.

Abstract: Methods and apparatuses for measurement in a wireless communication system are provided. In some embodiments, an apparatus transmits a measurement report for one carrier and/or bandwidth part (BWP) that is based on measurement information for another carrier and/or BWP. Further, the apparatus may switch between different carriers and/or BWPs to obtain measurement information in advance of scheduling transmissions on those different carriers and/or BWPs. Potential advantages include a reduction in measurement overhead at the apparatus.
