Abstract: A UE may receive, from a base station, scheduling information for a first DL transmission associated with half-duplex mode and a second DL transmission associated with full duplex mode, determine priorities of the first and second DL transmissions, and monitoring for a higher priority DL transmission among the first and second DL transmissions. The UE may transmit a first UL transmission associated with a half-duplex mode and a second UL transmission associated with a full duplex mode, and the base station may determine priorities of the first and second UL transmissions. The priority may be determined by the duplex mode or the content of the first and second DL transmissions and the first and second UL transmissions.

Abstract: Aspects described herein relate to quasi co-location (QCL) indications in an integrated access and backhaul (IAB) system. In an example, an IAB node may determine a spatial relation between a first communication of a DU entity and a second communication of one of the DU entity or a co-located MT entity. The IAB node may further configure a beam of at least one of the MT or the DU based on the determined spatial relation. The IAB node may further communicate using the beam with at least one entity.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a plurality of random access occasions for uplink message transmission to a base station. The UE may determine that a first portion of the plurality of random access occasions is unavailable for use by the UE as a result of the base station operating in a full duplex mode. The UE may select one or more random access occasions from a second portion of the plurality of random access occasions instead of from the first portion based at least in part on the determining. The UE may transmit a random access message to the base station during the one or more random access occasions from the second portion.

Abstract: Methods, systems, and devices for wireless communications are described. A relay device may detect an upstream radio link failure (RLF) associated with an upstream link of a wireless backhaul, where the wireless backhaul includes a first wireless link between the relay device and a first upstream backhaul device. The relay device may provide a first indication of the upstream radio link failure over a second wireless link between the relay device and a first downstream device. The relay device may establish a third wireless link with a second upstream backhaul device based on the detected upstream radio link failure. The relay device may provide multiple-access services to one or more downstream devices, where providing the multiple-access services is based on backhaul communications between the relay device and the second upstream backhaul device over the third wireless link.

Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for different tone spacing schemes for different channels. Methods, systems, and devices also provide for different tone spacing schemes for different stages of communication between a UE and a base station. The base station may indicate, to the UE, the tone spacing scheme in a control channel, a synchronization signal, or a reference signal and the tone spacing scheme may be selected by the base station from available tone spacing schemes for communication. Tone spacing schemes may also be referred to as numerologies.

Abstract: A solution to enable synchronization and establishing links among the APs using available RATs with minimum modifications is provided. In one aspect, an apparatus may determine a first set of resources to be used for establishing network access for a set of UEs. The apparatus may determine a second set of resources for establishing backhaul links with a set of base stations. A resource schedule of the apparatus may include the first set of resources and the second set of resources. In another aspect, an apparatus may be a first base station. The first base station may receive a set of reports from a set of base stations. The first base station may determine a resource schedule for a second base station within the set of base stations based on the set of reports. The first base station may transmit the resource schedule to the second base station.

Abstract: A first control node may communicate with a user equipment (UE) using an integrated access and backhaul (IAB) network, and a second control node may manage a configuration of the IAB network. The second control node may not have the information needed to configure the IAB network, such as quality of service (QoS) information associated with a data radio bearer (DRB) used for communications between the first control node and the UE, and thus may not be able to configure a user plane interface tunnel and/or a radio link control (RLC) channel to assist with satisfying the QoS level. Some techniques and apparatuses described herein enable the second control node to receive QoS information associated with setting up a user plane interface tunnel between the first control node and an IAB node that serves a UE for which the user plane interface tunnel is being set up.
