  • Patent number: 11419078
    Abstract: Indication of globally synchronous communications mode is disclosed. A first node may detect an indication signal transmitted by a second node at a synchronization boundary of a shared communication channel. The indication signal is configured to identify a first transmission synchronization mode of the second node. The first node may then adjust its communications configuration in response to the indication signal. In making such adjustments, the first node may either contend for communications on the shared communication channel using the first transmission synchronization mode or refrain from attempting the communications on the shared communication channel using a second transmission synchronization mode.

  • Patent number: 11412524
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device that uses a first radio access technology (RAT) may identify a transmission timing scheme for a shared radio frequency spectrum band, the transmission timing scheme comprising a first set of time intervals allocated for transmissions using a first RAT and a second set of time intervals allocated for transmissions using a second RAT. The wireless device may transmit, during a time interval of the first set of time intervals, a channel reservation signal indicating an end time of the time interval and indicating that the wireless device uses the first RAT. The wireless device may transmit, based at least in part on the transmitted channel reservation signal, over the shared radio frequency spectrum band during at least a portion of the time interval before the end time of the time interval.

  • Patent number: 11382112
    Abstract: Methods, systems, and devices for wireless communications are described that provide for a wireless device with dual subscriptions to prioritize a subscriber. A user equipment (UE) may configure a first channel for a first subscription and a second channel for a second subscription. The UE may determine one or more slots for the first subscription for communicating in a first direction and for the second subscription for communicating in a second direction, where the first and second directions are different. The UE may prioritize communications of the first subscription according to the determined slots. The prioritizing may be based on the direction, whether the communications are scheduled or configured, or whether the slot includes a monitoring occasion. The UE may communicate in the first direction according to the first subscription.

  • Patent number: 11363493
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a secondary component carrier (CC) for a user equipment (UE) which is not aligned on a valid channel raster entry. The location of the secondary CC may be indicated based on a reference location relative to another frequency or another CC. The reference location of the secondary CC may be the center of the new CC, an edge of the secondary CC, the position of a subcarrier within the secondary CC, or the position of a resource. In some examples, the reference location of the secondary CC may be indicated relative a currently used CC, an arbitrary channel entry, or an absolute frequency location. In some examples, the relative location may be provided in resource blocks or subcarriers and the subcarrier spacing (SCS). The base station may indicate the width of the secondary CC to the UE.

  • Patent number: 11272510
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a channel raster associated with a plurality of resource blocks of a channel. The plurality of resource blocks may have an asymmetric relation with respect to the channel raster. The base station may configure, based at least in part on the asymmetric relation, a message to indicate a resource block offset metric that comprises an indication of the channel raster and location information associated with a first resource block of the plurality of resource blocks. The base station may transmit the message to convey the indication of the resource block offset metric.

  • Publication number: 20220060920
    Abstract: Certain aspects of the present disclosure provide techniques for interference mitigation. An exemplary method performed by a base station generally includes determining, based on a location of another base station and information regarding the other base station, that the other base station is likely to experience interference while receiving an uplink transmission due to a downlink transmission by the base station and forming a null in a beam of the downlink transmission in a direction matching the location of the other base station.

  • Publication number: 20210400730
    Abstract: Adaptive energy detection (ED) threshold medium access is discussed based on deployment and traffic type. The network nodes sharing a shared communication network are configured with multiple discrete ED thresholds or a range of ED values. As a transmitting node prepares to attempt access to the shared communication spectrum, it identifies an access trigger condition within the network. Such a condition may include traffic type, deployment, or access conditions. In response to detecting an access trigger condition, the transmitting node may select an ED threshold associated with the access trigger condition. Alternatively, upon detection of the access trigger condition, the transmitting node may implement a random ED threshold from the candidate range of ED threshold values.

  • Patent number: 11153830
    Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.

  • Publication number: 20210321416
    Abstract: Methods, systems, and devices for wireless communications are described. that support asymmetric time division duplexing (TDD) coexistence among different operators having adjacent nodes in wireless networks. A baseline TDD configuration may be established for a set of frequency bands, that provides that uplink (UL) transmissions and downlink (DL) transmissions within a set of frequency bands are aligned and result in relatively little or no interference among different operators. An operator may determine that a TDD configuration that is different from the baseline TDD configuration may be beneficial and may select an interference mitigation procedure and communicate with one or more UEs using the interference mitigation procedure and TDD configuration that is different than the baseline TDD configuration.

  • Publication number: 20210266969
    Abstract: This disclosure provides wireless nodes, methods, apparatus, means plus and computer-readable mediums for randomly determining detection thresholds, such as energy detection (ED) thresholds, and then using such randomly determined thresholds to determine whether a channel is busy or idle when performing clear channel access (CCA). In some implementations, a new random detection threshold may be determined at a start of each backoff or each subsequent backoff slot. In some other implementations, a range of energy from which the detection threshold is randomly determined may depend on measurements of traffic activity, the number of MAC addresses observed or the priority of the traffic.
