Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first control signaling identifying a demodulation reference signal (DMRS) pattern that may be uniformly distributed in a time domain and a frequency domain. The DMRS pattern may include a first set of resource elements for the DMRS, a second set of resource elements for guard tones adjacent to and greater in frequency than the first set of resource elements, and a third set of resource elements for guard tones adjacent to and lower in frequency than the first set of resource elements. The UE may receive second control signaling that schedules a data signal to be communicated between the UE and a network node in a set of time-frequency resources. The UE may communicate the data signal according to the second control signaling and the DMRS according to the DMRS pattern.

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: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a base station may transmit, to a user equipment (UE), an indication of a dynamic switch between slot formats. The base station and the UE may communicate first data in one or more first slots according to a first slot format. The first slot format may be a first cyclic prefix-based or guard interval-based slot format. The base station may transmit control signaling to the UE to indicate a second slot format different from the first slot format. The second slot format may be a second cyclic prefix-based or guard interval-based slot format. The UE and the base station may switch to communicating second data in one or more second slots in accordance with the second slot format based on the control signaling.

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: In one aspect, a method of wireless communication includes determining, by a user equipment (UE), beamforming information for two or more frequency bands. The method also includes determining, by the UE, an inter-band carrier aggregation (CA) mode based on the beamforming information and one or more conditions. The method further includes transmitting, by the UE, a message indicating the inter-band CA mode. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Multiple transmitting user equipments (UEs) may send sidelink data transmissions. Receiving sidelink UEs may map sidelink feedback interlaces corresponding to detected sidelink data transmissions to sidelink feedback resources of a common sidelink feedback symbol according to an interlace mapping rule (e.g., defining which contiguous or non-contiguous frequency resources the UE is to use for transmitting sidelink feedback for the received sidelink data messages). The receiving UEs may map one or more replicas of initial interlaces of sidelink feedback resources to additional available resources of the sidelink feedback resources in the common feedback symbol.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal that is transmitted by a base station with a modulation signature associated with a reconfigurable intelligent surface (RIS) or a repeater and redirected by the RIS or the repeater using modulation that reverses the modulation signature associated with the RIS or the repeater. The UE may decode the signal, wherein the signal is decodable by the UE based at least in part on the signal being redirected by the RIS or the repeater using the modulation that reverses the modulation signature associated with the RIS or the repeater. Numerous other aspects are described.

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.
