Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects generally relate to reducing interference in a user equipment (UE) with respect to non-cell defining synchronization signal and physical broadcast channel block (NCD-SSB) communications. Some aspects more specifically relate to configuring the UE to mitigate interference caused by collisions between the NCD-SSB and a cell-defining SSB (CD-SSB). Some aspects more specifically relate to configuring the UE to mitigate interference and/or other issues that might occur when at least a portion of the NCD-SSB is received during one or more downlink slots or symbols and one or more uplink slots or symbols.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) obtains, from a first cell, a first downlink reference timing and a first reference signal received power (RSRP) measurement, wherein the first RSRP measurement is a first reference RSRP, determines that the first downlink reference timing has changed based on a cell reselection from the first cell to the second cell performed while in a radio resource control (RRC) non-connected state, and obtains, from the second cell, while in the RRC non-connected state, based on the first downlink reference timing having changed more than a threshold, a second downlink timing and a second RSRP measurement, wherein the second RSRP measurement is a second reference RSRP.

Abstract: A base station may identify a first antenna configuration of the base station and a second antenna configuration of a wireless device. The base station may select one or more codebook-based precoders for communication with the wireless device with LOS MIMO. The one or more codebook-based precoders may include at least one of a Legendre precoder, a block-DFT precoder, a DFT precoder, a block-Walsh precoder, a Walsh precoder, a block-Legendre precoder, a Kronecker Legendre precoder, a Kronecker block-DFT precoder, or a Kronecker block-Walsh precoder. The base station may transmit, to a wireless device, an indication of a second codebook-based precoder for transmission from the wireless device to the base station with LOS MIMO. The base station and the wireless device may communicate with each other with LOS MIMO based on one or more codebook-based precoders.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate, to a base station, a capability of the UE to use a channel measurement resource for both a joint transmission hypothesis and a single transmission hypothesis. The UE may receive, based on indicating the capability of the UE, a configuration message indicating a first channel measurement resource that is associated with a first transmission configuration indicator state and that is configured for a first joint transmission hypothesis. The UE may obtain a channel measurement for both the first joint transmission hypothesis and a first single transmission hypothesis using the first channel measurement resource based on the configuration message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a first channel measurement resource (CMR) associated with a first transmission configuration indicator (TCI) state and a second CMR associated with a second TCI state. The UE may also receive an indication of a first interference measurement resource (IMR) associated with the first CMR and a second (IMR) associated with the second CMR. The UE may obtain an interference measurement using the first IMR, the second IMR, or both, for a channel state information (CSI) report for ajoint transmission hypothesis associated with the CMR and the second CMR. The UE may transmit the CSI report based at least in part on the interference measurement (s).

Abstract: Aspects of the disclosure are directed to quantized orthogonal modulation for non-coherent over-the-air (OTA) federated learning (FL). In some examples, a wireless device may compare a gradient to a threshold value to determine whether the gradient satisfies a threshold condition. The wireless device may also output, for transmission to a network node, signaling via one of a first resource or a second resource, wherein the signaling is outputted via the first resource if the gradient satisfies the threshold condition, and wherein the signaling is outputted via the second resource if the gradient does not satisfy the threshold condition.
