  • Publication number: 20200205102
    Abstract: When time locations of synchronization signal (SS) blocks (SSBs) are fixed within an SS burst set, the time locations and the slot pattern may be incompatible. In this case, the base station may not be permitted to transmit that SSBs that overlap in time with a configured uplink symbols because the base station is configured to receive uplink communications during this time, rather than transmit downlink communications during this time. As a result, the base station may have fewer opportunities to transmit SSBs, which may lead to increased latency due to delays in accessing the base station, may reduce spectral efficiency due to fewer opportunities to indicate beamforming parameters and/or fewer beams being used for communications, and/or the like. Some techniques and apparatuses described herein permit the base station to flexibly configure time locations of SSBs within an SS burst set, thereby reducing latency, improving spectral efficiency, and/or the like.

  • Publication number: 20200170010
    Abstract: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

  • Publication number: 20200154336
    Abstract: Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.

  • Publication number: 20200145965
    Abstract: A parent access node may establish a first link with a child access node. In some cases, the parent access node may determine to release a resource of the first. The parent access node may transmit downlink signaling indicating release of the resource. As such, the child node may schedule a child link resource (e.g., a parent-controlled resource) corresponding to the released resource. The child node may then communicate with a child node of its own in accordance with the scheduling of the child link resource. In some cases, the resource release indication may be associated with a one-time resource release, or may be associated with a semi-persistent release (e.g., until the parent node reclaims the released resources). In some examples, the child node may transmit an uplink message to request resources from the parent node (e.g., and the resource release may be based on the request).

  • Publication number: 20200145991
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive association information for a set of soft resources of the wireless node. The association information may indicate one or more parent nodes associated with a soft resource of the set of soft resources. The set of soft resources may be configurable as schedulable or non-schedulable for the wireless node. The wireless node may determine one or more release indications associated with the soft resource. The wireless node may schedule on the soft resource based at least in part on determining the one or more release indications. Numerous other aspects are provided.

  • Publication number: 20200146099
    Abstract: In some aspects, a node may configure whether a set of soft time resources is to be conditionally released or unconditionally released. The set of soft time resources may be configurable in a schedulable state or a non-schedulable state. The set of soft time resources may be schedulable subject to at most a directionality constraint when unconditionally released and, when conditionally released, being schedulable subject to: the directionality constraint and one or more conditions other than the directionality constraint if the set of soft resources is configured subject to the directionality constraint, or at least one of the directionality constraint or the one or more conditions other than the directionality constraint if the set of soft resources is not configured subject to the directionality constraint. The node may transmit a configuration that indicates whether the set of soft time resources is conditionally released or unconditionally released in the schedulable state.

  • Publication number: 20200128539
    Abstract: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

  • Patent number: 9642105
    Abstract: An access point (e.g., a femto cell) that is connected in an active call with an access terminal may cooperate with that access terminal or another access terminal to derive timing information from one or more neighboring access points (e.g., macro access points). In addition, an access point may cooperate with an idle access terminal to derive timing information from one or more neighboring access points. For example, an access terminal may determine the difference between pilot transmission timing or frame transmission timing of a femto cell and a macro cell, and report this timing difference to the femto cell. Based on this timing difference, the femto cell may adjust the timing and/or frequency of its transmissions so that these transmissions are synchronized in time and/or frequency as per network operation requirements.
