Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a millimeter wave repeater may communicate with a base station using a first set of antennas and a first beamforming configuration for the first set of antennas, the first beamforming configuration being selected from a beamforming codebook that includes multiple beamforming configurations; and communicate with one or more user equipments (UEs) using a second set of antennas and a second beamforming configuration for the second set of antennas, the second beamforming configuration being a fixed configuration that does not change for different communications between the second set of antennas and the one or more UEs. Numerous other aspects are provided.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a client wireless device may transmit a random access channel (RACH) preamble on a first time domain resource to a recipient such as a host wireless device. The client wireless device may later transmit a second RACH message to the recipient on a second time domain resource after the first time domain resource. The second time domain resource may be defined by a mapping from the first time domain resource. The recipient may transmit a third RACH message establishing a communication session between the host wireless device and the client wireless device. The second RACH message may include one or more of: an identifier of the wireless device; an identifier of the recipient of the second RACH message; a resource configuration for subsequent RACH messages; or timing information.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may concurrently configure repeaters in a wireless communications system via multicast control messaging. The base station may identify a quantity of repeaters in communication with the base station. Some repeaters may be in communication with the base station via other repeaters, for example in a chain configuration. The base station may prepare a multicast message including control information for the quantity of repeaters. In some examples, the base station may transmit the multicast message directly to each repeater in the quantity of repeaters, which may be referred to as a single hop control transmission. In some examples, the base station may transmit the multicast message via one or more chains of repeaters, which may be referred to as a multi-hop control transmission. The described techniques may include improved repeater operations and promote efficient repeater communications, among other benefits.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may perform a slot reservation procedure to obtain a TxOP for communicating with a second UE. The slot reservation procedure may be performed in an earliest slot in the TxOP in which the first UE has data to send to the second UE. The apparatus may transmit the data to the second UE using at least one slot in the TxOP when the slot reservation procedure is successful. In certain aspects, all remaining slots in the TxOP may be reserved for the first UE when the slot reservation procedure is successful. The apparatus may refrain from performing a subsequent slot reservation procedure in another slot in the TxOP when the slot reservation procedure is unsuccessful unless an end of transmission signal is received during the TxOP.

Abstract: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device of a multi-hop wireless network receives a first transmission timing adjustment command. The first wireless communication device communicates, with a second wireless communication device of the multi-hop wireless network based on at least the first transmission timing adjustment command, a first communication signal including backhaul data. The first wireless communication device communicates, with a third wireless communication device of the multi-hop wireless network based on the at least the first transmission timing adjustment command, a second communication signal.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a relay node may determine a first predicted motion of a first vehicle including a first wireless communication device having a first established communication channel with the relay node. The relay node may determine that the first predicted motion will trigger a communication condition for the first vehicle and a second wireless communication device having a second established communication channel with the relay node. The relay node may reserve radio resources for a third communication channel between the first wireless communication device and the second wireless communication device.

Abstract: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device receives synchronization information associated with one or more wireless communication of a multi-hop wireless network. The first wireless communication device determines a transmission timing adjustment for a second wireless communication device of the one or more wireless communication devices based on at least some of the synchronization information. The first wireless communication device transmits a message instructing the second wireless communication device to communicate with a third wireless communication device of the one or more wireless communication devices based on the transmission timing adjustment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a control node may receive a resource management indication from a network node to identify a resource utilization with communications of the network node; determine, based at least in part on the resource management indication, a collision management configuration for the network node; and transmit information associated with the collision management configuration based at least in part on the determination of the collision management configuration. Numerous other aspects are provided.

Abstract: High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support power saving of wireless repeaters. Generally, the described techniques provide for wireless device (e.g., wireless repeater, wireless relay device, etc.) power savings in the absence of an attached (e.g., connected) user equipment (UE). For example, a wireless repeater may operate in a power saving mode and monitor for control information from a base station according to a slow state (e.g., according to a relatively long monitoring periodicity). Upon detection of possible UE attachment to the base station (e.g., upon detection of a random access channel (RACH) message), the wireless repeater may transition to monitoring for control information from the base station according to a fast state (e.g., according to a relatively short, or more frequent, monitoring periodicity).
