Abstract: Methods, systems, and devices for wireless communications are described that provide for cooperative full-duplex techniques for sidelink communications. A first device that supports full-duplex communications may transmit a first message to a second device while concurrently receiving a second message from a third device. The first device may determine a set of parameters that indicate a presence of one or more objects that cause interference at the first device based on communicating with the second and third devices. The set of parameters may include location information, directional beam information, main beam information, and null interference beam information, or velocity information, or any combination thereof. The first device may broadcast an indication of the set of parameters to other devices. In some examples, a device that receives the set of parameters may determine communications parameters for communication with other devices that accounts for the indicated objects.

Abstract: An apparatus are provided for wireless communication at a base station with improved PBCH construction and decoding. The base station apparatus constructs a PBCH payload, wherein a bit location is selected for encoding a plurality of bits of the PBCH based on an estimated reliability for the corresponding bits location wherein the plurality of bits comprises frozen bits, unknown bits that are unknown to a user equipment, and potentially known bits that are potentially known by the user equipment. The apparatus transmits the PBCH payload in at least one of a plurality of SS blocks. A UE receiving the PBCH decodes the PBCH based on a successive decoding order. The successive decoding order may be based on an estimated reliability for the corresponding bits, e.g., in which potentially known bits are decoded prior to unknown bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may receive a discovery signal from a host device; determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing; configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing; and transmit the response to the host device using the configured reference timing. Numerous other aspects are provided.

Abstract: An intermediary base station supporting mobile terminal (MT) functionality and/or a user equipment (UE) may receive a time alignment (TA) command and associated timer value from one or more distributed units (DUs) and/or a central unit (CU) of a parent base station. The TA command and timer value may be based on an experienced or potential timer expiration associated with a TA of a communication link. The TA command may specify an updated TA value and a timer reset for scheduling communications on the communication link. In some examples, the TA command may be in response to a TA command request provided by the MT or UE on allocated resources or configurations indicated by the parent base station. In other cases, the TA command may be in response to a random access procedure on allocated resources or configurations indicated by the parent base station.

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.
