Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, based at least in part on a first downlink reference signal transmitted from a first base station using a downlink reference signal frequency, a first frequency offset associated with transmissions between the UE and the first base station. The UE may determine, based at least in part on a second downlink reference signal transmitted from a second base station using the downlink reference signal frequency, a second frequency offset associated with transmissions between the UE and the second base station. The UE may transmit, to the first base station and the second base station, at least one uplink reference signal using an uplink reference signal frequency that is based at least in part on the first frequency offset and the second frequency offset.

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: Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.

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.
