Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node in a multi-hop network may receive a configuration for a notification signal, wherein the configuration indicates a receive (RX) resource to be used by the node to monitor for the notification signal and a transmit (TX) resource to be used by the node to transmit the notification signal, wherein the RX resource and the TX resource are included in a time period that also includes one or more other RX resources and one or more other TX resources to be used by one or more other nodes in the multi-hop network for the notification signal. The node in a multi-hop network may refrain from transmitting or receiving in any resources within the time period except for the RX resource and the TX resource. Numerous other aspects are provided.

Abstract: Systems and methods establishing and maintain a direct User Equipment to User Equipment communication link are disclosed. A User Equipment (UE) may receive a Sounding Reference Signal (SRS) from a neighboring UE. The UE may determine from the SRS that the UE is a good candidate for a direct link. The UE may also determine from the SRS an ID associated with the neighboring UE. The UE may send a direct link request to the UE serving gNB. The serving gNB may forward the request to a gNB serving the neighboring UE. The gNBs may negotiate a joint schedule for a beam a UE to UE beam search. The beam search may be conducted using SRS resources. The results of the beam search may be sent to the gNB and the gNB may determine a beam pair for a direct link.

Abstract: Systems and methods establishing and maintain a direct User Equipment to User Equipment communication link in a gNB are disclosed. A gNB may determine that direct UE to UE link should be established in a cell. The gNB may transmit information to a first and second UE to enable a device to device beam search procedure. The first and second UE may perform the beam search and report the result to the gNB. The gNB may determine the appropriate beam for the first and second UE to establish a communication link.

Abstract: Efficient opportunistic communications in integrated access and backhaul (IAB) frameworks are provided allowing scheduling nodes and scheduled nodes to communicate within an allocated set of resources based on a different configuration than for non-opportunistic communications using a different set of resources. An additional set of available resources may be allocated for coordinated communications between a parent IAB-node and the child IAB-node. Resources within this available set are associated with a first configuration, and when prior coordination exists, the parent IAB-node and child IAB-node may communicate based on this first configuration over this available set of resources. However, when prior coordination does not exist, the parent IAB-node and child IAB-node may opportunistically communicate over the allocated set of resources based on a second configuration different than the first configuration. Using different configurations, power may be conserved and resources managed more efficiently in opportunistic communications where unsuccessful transmissions may be more likely.

Abstract: A first apparatus may puncture, in at least two subslots, a first type of data or control information with a second type of data or control information. The first apparatus may bundle the least two subslots within a subframe, and the subframe may include a portion for carrying acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of data or control information. The first apparatus may communicate with a user equipment (UE) during the at least two subslots within the subframe. A second apparatus may receive ACK/NACK information associated with a second type of data or control information. The second apparatus may reduce a transmission power for a first type of data or control information during a subsequent subframe when the ACK/NACK information indicates a negative acknowledgement.

Abstract: Disclosed are techniques for receive beam selection for measuring a reference radio frequency (RF) signal. In an aspect, a first node determines a type of measurement to be performed on the reference RF signal, selects a receive beam based on the type of measurement to be performed on the reference RF signal, generates the selected receive beam, receives, from a second node, using the generated receive beam, the reference RF signal transmitted on a wireless channel, and performs one or more measurements on the received reference RF signal according to the type of the measurement to be performed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) and/or a base station (BS) may identify in connection with a link failure of a primary cell, a resource in a secondary cell. The UE and/or the BS may communicate control signaling with the BS using the resource in the secondary cell as a response to the link failure of the primary cell. Numerous other aspects are provided.

Abstract: A UE may identify a first indication associated with a first signaling to be received in a time interval and identify a second indication associated with a second signaling to be received in the time interval. The UE may select to receive and receive, in the time interval, at least one of the first signaling or the second signaling based on at least one of the first or second indications. One or more of the first and second indications may be received from a BS or determined by the UE via predefined or other means. A BS may convey indications of the first and/or second signaling. The first and second indications may be transmitted sufficiently before the signaling in an effort to allow the UE to select and tune its receiver beam in the direction of the signaling to be received.

Abstract: Aspects of the present disclosure are directed to device-to-device (D2D) and, more particularly, vehicle-to-vehicle (V2V) communication in which an efficient ranging protocol allows efficient ranging-assisted vehicle positioning. A vehicle transmits a first slot ID in a first control period, to indicate a first time slot for transmitting a first ranging signal in a ranging cycle including a plurality of time slots. The vehicle transmits the first ranging signal in the first time slot in the ranging cycle. From a second vehicle, the first vehicle receives a second ranging signal in a second time slot that is different from the first time slot in the ranging cycle. The first vehicle determines a first time-of-arrival (ToA) of the second ranging signal when received by the first vehicle, and transmits the first ToA in a second control period.

Abstract: In a process of beam change, the base station transmits a beam change instruction to a user equipment to confirm a change from a current beam to another beam. The base station determines to change from a first beam to a second beam. The base station generates a beam change instruction to indicate the determination to change from the first beam to the second beam. The base station transmits, to a UE, the beam change instruction in a downlink control information (DCI). The base station determines whether or not the beam change instruction is detected by the UE.
