Abstract: The present disclosure provides methods and apparatuses for multi-carrier transmissions over adjacent channels that reduce self-jamming due to asymmetric interference. In an aspect, a large bandwidth load-base equipment (LBE) carrier may be provided such that CCA is performed jointly over the entire bandwidth. In another aspect, additional CCA timeslots may be used to synchronize the two carriers. In a further aspect, an extended CCA may be performed on a primary unlicensed carrier while a simple CCA may be performed on a secondary unlicensed carrier. In yet another aspect, LBE may be deployed on some carriers while frame-base equipment (FBE) may be deployed on other carriers.

Abstract: Aspects described herein relate to scheduling data for transmission over a plurality of component carriers. A base station can determine to increase bandwidth utilization over at least one component carrier of a plurality of component carriers assigned to a plurality of user equipments (UE). The base station can assign a plurality of resource blocks over the at least one component carrier to one or more fictitious UE identifiers and transmit data signals over the plurality of resource blocks to increase bandwidth utilization over the at least one component carrier. One or more network nodes may determine the one or more fictitious UE identifiers and may determine related resource assignment for canceling interference from data transmitted for the fictitious UE identifiers, performing channel estimation, etc.

Abstract: Base stations (such as small cells) may support active and dormant states. To facilitate state transitions, these cells may transmit discovery signals. The transmission design of both discovery signals and network synchronization signals from small cells should provide for regular periodicity, while supporting the benefit of transitioning between active and dormant states. Disclosed is a method, a computer program product, and an apparatus that determine a first reference signal for at least one of discovery or measurement, and a second reference signal for synchronization, where both the first reference signal and the second reference signal are based on a same type of reference signal.

Abstract: A backhaul quality is measured. One or more subsets of cell identifiers having a mapped backhaul quality that maps to the measured backhaul quality are identified. The one or more subsets have a set of cell identifiers associated therewith. A network is queried to indicate one or more cell identifiers in the identified subset of cell identifiers available for a user equipment (UE) relay. One of the one or more indicated cell identifiers is selected. If more than one subset of cell identifiers has a mapped backhaul quality that maps to the measured backhaul quality, first and second subsets having respective first and second mapped backhaul qualities are selected and the backhaul qualities are compared relative to a backhaul quality threshold. The mapped backhaul quality that most satisfies the backhaul quality threshold is identified for the network query.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide assisted access to a serving cell for wireless communications. A UE may receive a broadcast system information message from the first cell. The broadcast system information message may include system information usable for communicating with the second cell. Using the received system information, the UE may transmit, to the first cell, a random access channel (RACH) preamble message in order to establish a connection with the second cell. The first cell may transmit, to the second cell in response to receiving the RACH preamble message, a wake-up signal.

Abstract: Certain aspects of the present disclosure provide techniques for the coexistence of wireless telecommunication devices (e.g., 4G, 5G, and/or 6G devices) and UWB devices operating in a same frequency band. A method generally includes receiving, from a first user equipment (UE), first signaling indicating an initiation of a first ultra-wideband ranging session between the first UE and an ultra-wideband device; determining a location of the first UE after receiving the first signaling; and performing one or more first interference mitigation processes configured to reduce channel interference in a first ultra-wideband channel used for the first ultra-wideband ranging session based on, at least, the location of the first UE.

Abstract: Wireless communications systems and methods related to UE cooperation are provided. A base station (BS) may assist a UE in discovering and cooperating with other UEs. A BS may collect information from candidate cooperative UEs such as UE capability and availability. This information may be broadcast to other UEs or may be transmitted to a UE at the UE's request. The UE may, upon receipt of this information, use it to aid in discovering the candidate cooperative UEs and/or establishing a connection.

Abstract: A method of wireless communication by an initiating device, includes acquiring a channel occupancy time (COT) including multiple subsets of COT sharing resources. Each of the subsets includes fewer resources than the entire COT. The method also includes configuring a first responding device with a first of the subsets of COT sharing resources. The method further includes configuring a second responding device with a second of the subsets of COT sharing resources. A method of wireless communication by a responding device receives, from an initiating device, a first subset of multiple subsets of channel occupancy time (COT) sharing resources. The first subset differs from a second subset of COT sharing resources configured for another device. The method also includes selecting transmission resources from the first subset of COT sharing resources in response to detecting the initiating device acquired the COT, and then transmitting data on the selected transmission resources.
