Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a first type of timing advance indicator, wherein the first type of timing advance indicator is associated with a first type of connection associated with a first group of wireless nodes, of a network, that includes the first wireless node and the second wireless node and is different from a second type of timing advance indicator used for a second type of connection associated with a second group of wireless nodes of the network. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node based at least in part on the first type of timing advance indicator. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first device may be in communication with a second device and may receive, from the second device, DCI in a downlink control channel and a message in a downlink shared channel. The message in the downlink shared channel may include an indication of a system information update that is relevant to the first device and may include information relating to one or more system information parameters that are updated. The first device may determine the system information update based on the DCI and the indication in the message and may acquire system information accordingly. The first device may update the system information of the first device based on the acquired system information update and may communicate with the second device using the updated system information.

Abstract: A relay node supporting mobile terminal (MT) functionality and distributed unit (DU) functionality may receive a timing advance (TA) value for uplink synchronization associated with a timing alignment timer from a parent node. In some cases, the timing alignment timer may expire prior to the relay node receiving a next TA value. Upon expiration of the timing alignment timer, the relay node may initiate a second timer (e.g., a transition timer) associated with the transitioning of a DU entity of the relay node to a DU transition state. The DU transition state is associated with certain DU behavior for serving child nodes while the transition timer is active. Configuration of the DU transition state may be identified by the relay node, or received from a parent node. In cases where the transition timer expires prior to receiving a next TA value, the DU may declare a loss of uplink synchronization.

Abstract: A base station central unit (CU) may receive a measurement report from one or more user equipments (UEs). The CU may identify a scheduling plan indication (SPI) for one or more scheduling nodes in a network, based at least in part on the received measurement reports. The SPI may specify a pattern of scheduling states, over a period of time, to be used by the one or more scheduling nodes to schedule communication resources for one or more UEs in the network. The scheduling states may (e.g., based on an interference profile determined from the received measurement reports) specify UEs or other communication resources for transmission scheduling decisions made by the scheduling nodes, or may specify beam patterns for beamforming procedures performed by the scheduling nodes. In some cases, the scheduling nodes may identify tentative SPIs, which the CU may pass amongst other scheduling nodes for distributed scheduling coordination schemes.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a measurement configuration, from a second wireless device, to support full-duplex operation using a shared resource. The first wireless device may transmit, via the shared resource, a first signal via a first transmission beam using a first antenna array of the first wireless device. The first wireless device may monitor, in accordance with the measurement configuration, the shared resource using a first receive beam via a second antenna array of the first wireless device. The first wireless device may then transmit a measurement report to a second wireless device based on the monitoring. The second wireless device may transmit, to the first wireless device, a duplexing configuration configuring the full-duplex operation of the first wireless device based on the measurement report.

Abstract: Various aspects include methods for beam sweep configuration of a millimeter wave (MMW) repeater in a fifth generation (5G) network during random access channel (RACH) procedures. Various embodiments include receiving an RACH 1 message relayed by an MMW repeater, determining a beam sweep schedule for use by the MMW repeater in relaying a random access response (RAR) message in response to the RACH 1 message, wherein the beam sweep schedule indicates a series of RAR messages to be sent successively and a different transmit (TX) beam sweep configuration to be used by the MMW repeater for each of the series of RAR messages, generating an RAR control message indicating the beam sweep schedule, sending, by the processor of the network device, the RAR control message to the MMW repeater, and sending the series of RAR messages to the MMW repeater.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. A wireless node may determine a pattern for transmitting multiple synchronization communications in one or more synchronization communication sets. The wireless node may determine a set of resources, in the one or more synchronization communication sets, to be used to transmit the multiple synchronization communications based at least in part on the pattern. The wireless node may transmit the multiple synchronization communications using the set of resources. A first synchronization communication, of the multiple synchronization communications, may be frequency division multiplexed with a second synchronization communication. Numerous other aspects are provided.
