Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a first IAB node determining an adjustment to at least one parameter corresponding to a cell coverage of the first IAB node based at least in part on a geographic proximity of a cell relative to the first IAB node. For example, the first IAB node may determine to adjust the parameters based reference signal measurements, signal quality measurements (e.g., received from child nodes or user equipments (UEs)), etc. In another example, the first IAB node may receive an instruction from a central unit (CU) of the IAB network to adjust the at least one parameter. The first access node may transmit an indication of the adjustment to the at least one parameter. For example, the first access node may signal the adjustments to the CU, child IAB nodes, UEs and/or, other IAB nodes.

Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: Aspects of the disclosure relate to methods and apparatus for scheduling traffic between a transmitting device and a receiving device. A transmitting device negotiates with a receiving device to reserve a plurality of slots for communicating data with the receiving device. The transmitting device then sends, at a beginning of one slot of the reserved plurality of slots, a request-to-send (RTS) message indicating a number of slots of the reserved plurality of slots the transmitting device intends to use for transmitting the data. The transmitting device receives, from the receiving device, a clear-to-send (CTS) message in each slot of the number of slots based on the RTS message and transmits the data to the receiving device in each slot of the number of slots upon receiving the CTS message in each slot. Other aspects, embodiments, and features are also claimed and described.

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.
