Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for updating a slot format during full duplex (FD) operation. An example method by a user equipment (UE) generally includes receiving signaling for the UE to operate on at least one active bandwidth part (BWP) and participating in FD communications in the at least one active BWP on at least some symbols, based on a first slot format associated with the at least one active BWP.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first communication device may receive, from a second communication device, control signaling triggering a channel access procedure at the first communication device. In some case, the channel access procedure may be for accessing the shared radio frequency spectrum. The first communication device may then perform the channel access procedure based on the control signaling. In some examples, the first communication device may, based on the channel access procedure, transmit an indication of a channel occupancy initiated by the first communication device to the second communication device. The first communication device may relay communications between the second communication device and a third communication device during a channel occupancy time (COT) based on the transmitted indication of the channel occupancy initiated by the first communication device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive mobility state information associated with an integrated access backhaul (IAB) node. The mobility state information may include information associated with at least one of: a level of mobility of the IAB node, or a change in mobility of the IAB node. The wireless communication device may perform an operation based at least in part on the mobility state information associated with the IAB node. In some aspects, a wireless communication device may determine that mobility state information associated with an IAB node is to be transmitted, and may transmit the mobility state information associated with the IAB node based at least in part on the determination. Numerous other aspects are provided.

Abstract: Aspects relate to techniques for mitigating wireless communication interference. For example, one or more of a cyclic prefix length, a subcarrier spacing, a beam pair, or a frequency domain separation may be changed to mitigate the effects of inter-symbol interference (ISI) at a UE or a base station. A UE may measure a received timing difference between a time at which the UE receives a downlink transmission and a time at which energy from an uplink transmission by the UE is received by the UE. If this received timing difference exceeds a specified duration of time (e.g., the length of a cyclic prefix), the ISI at the UE may increase. In some examples, the interference mitigation techniques described herein may be invoked if there is an increase in the measured received timing difference.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a node or a base station. In one aspect, the apparatus may receive, via a first set of resources, communication including at least one data packet, the first set of resources allocated for a reception entity of the node. The apparatus may also decode, at the reception entity, the at least one data packet during a decoding period, the decoding period including a decoding start time and a decoding completion time. Additionally, the apparatus may transmit, via a second set of resources, the communication including the at least one data packet to a next hop node, the second set of resources allocated for a forwarding entity of the node, at least one first resource overlapping with at least one second resource.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support communication between one or more network entities and user equipment (UEs) via configurable intelligent surfaces. A first UE may transmit, to a second UE associated with a set of configurable intelligent surfaces, first information that indicates a tracking period and a data period that the second UE is to use to manage the configurable intelligent surfaces. The second UE may adjust the configurable intelligent surfaces for the communications between the first UE and network entities during the tracking period and the data period. The second UE may adjust the configurable intelligent surfaces based on measurement reports generated by the first UE based on communication during the tracking and data periods.

Abstract: Methods, systems, and devices for wireless communications are described. A repeater may apply a frequency translation and a phase rotation adjustment to a transmitted signal to avoid radio frequency interference. For instance, wireless repeater may receive a signal from a first device on a first carrier frequency. The wireless repeater may identify one or more interfering signals affecting the reception or transmission of the signal. The wireless repeater may then perform a frequency translation from the first carrier frequency to the second carrier frequency, and may also apply a phase rotation adjustment corresponding to the frequency translation. The wireless repeater may retransmit the signal including the phase rotation adjustment over the second carrier frequency to a second device in the wireless network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node of a parent node in an integrated access backhaul (IAB) network may determine communication information that includes one or more of a schedule or a configuration for a communication to be transmitted by the child node. The child node may be an IAB node, and the parent node may be an IAB donor or an intervening IAB node between the IAB node and an IAB donor. The child node may transmit the communication information to the parent node via a wireless backhaul link between the child node and the parent node. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or a base station may communicate a set of reference signals on a set of interference measurement resources. The set of interference measurements may be based on a first activation schedule of one or more reconfigurable intelligent surfaces (RISs). The UE or the base station may generate interference measurement information associated with the one or more RISs based on the set of reference signals. The base station may determine a second activation schedule of the one or more RISs or an allocation of resources for communicating with the UE based on the set of interference measurements. The base station may communicate with the UE based on the second activation schedule or the allocation of resources.
