Abstract: Different carriers and/or bandwidth parts (BWPs) may sometimes be utilized for wireless communication between two devices. In some prior wireless communication systems, e.g. in new radio (NR), the carrier used to transmit hybrid automatic repeat request (HARQ) feedback is semi-statically configured. However, semi-static configuration might be disadvantageous, e.g. for scenarios in which latency is a concern. In some embodiments, the carrier and/or BWP for transmitting HARQ feedback is instead dynamically indicated. More generally, when two devices are wirelessly communicating with each other, the carrier and/or BWP to be used for transmitting control information may be dynamically indicated.

Abstract: A timing advance (TA) value is a time offset that may be applied by a UE to compensate for the propagation delay of the UE and thereby cause the UE's uplink transmissions to be time synchronized with the uplink transmissions of other UEs. However, a UE may possibly operate in different states, and in some states (e.g. a power saving state) the UE does not maintain uplink synchronization. If the UE has information to transmit, and the UE is operating in a state in which there is no uplink synchronization, then the overhead of performing uplink synchronization in order to transmit the information must be incurred. Systems and method are instead disclosed for providing TA values to maintain timing synchronization, e.g. even when the UE is in a power-saving state.

Abstract: When a UE is in a power saving state, and the network has downlink data to send to the UE, a paging message may be transmitted in the downlink. Paging may have high overhead when beamforming is implemented. In some embodiments, a UE-specific notification is instead transmitted in a downlink beam pointed in the direction of the UE. The UE-specific notification may be a paging message specific to the UE that indicates that there is downlink data for transmission to that UE. However, more generally the UE-specific notification may be any type of downlink notification for a UE. The notification may include downlink beam information.

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: Current signaling structures in Long-Term Evolution and New Radio are not designed to accommodate flexible allocation of RF chains and/or antennas among radio access technologies (RATs) and/or between different transmission modes that support multiple transmissions/receptions/component carriers such as carrier aggregation, multiple-input multiple-output and/or multiple-transmit-receive point transmission/reception. Embodiments are disclosed in which an apparatus reports radio frequency (RF) capability information that supports such a flexible allocation of RF chains and/or antennas. In some embodiments, the RF capability information includes RF chain information indicating a number of RF chains operable in a first frequency range, and antenna information indicating, for each of a plurality of second frequency ranges within the first frequency range, a number of physical antennas operable within the corresponding second frequency range. A control signaling structure that supports flexible allocation of RF chains and/or antennas for a multi-RAT capable apparatus is also disclosed.

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: During operation of some wireless communication systems, a user equipment (UE) may monitor a control channel for a downlink notification. An example of a downlink notification is a paging notification. It is desirable to reduce the amount of power consumed when monitoring for downlink notifications. In some embodiments, power savings may possibly be provided by reducing the frequency resources (e.g. bandwidth) over which monitoring for downlink notifications is to occur. In some embodiments, there may be an association between: (i) UE type, capability, and/or service, and (ii) which configuration of resources is used for the monitoring of downlink notifications. In some embodiments, there may be different possible configurations of frequency resources to be used during an initial access procedure, with each configuration possibly having a different bandwidth of frequency resources allocated for the initial access procedure.

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: A first sensing coordinator in a radio access network may communicate a first signal with a second sensing coordinator through an interface link. The first sensing coordinator may include a sensing protocol layer, and may communicate the first signal through the interface link using the sensing protocol. Similarly, a second sensing coordinator may communicate a first signal with a first sensing coordinator in a radio access network through an interface link, with the second sensing coordinator including a sensing protocol layer and communicating the first signal through the interface link using the sensing protocol. A sensing device or apparatus may access an interface link through a radio access network and communicate a first signal, including a sensing configuration or sensing data, with a sensing coordinator that has a sensing protocol layer. The communicating may involve communicating the first signal through the interface link using a sensing protocol.
