摘要： The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

摘要： Methods, systems, and devices for wireless communications are described that support virtual resource block (RB) to physical RB mapping in duplex slots. The described techniques enable a user equipment (UE) to select an interleaving configuration such as a full duplex or half duplex interleaving configuration for a slot that may be configured for full duplex communications. In some cases, the UE may use a default interleaving configuration for a given slot or may determine the interleaving configuration based on a bandwidth part (BWP) position or resource bandwidth within the slot, such as a location within the frequency domain of a downlink BWP relative to an uplink BWP.

摘要： A method of wireless communication, by a user equipment (UE), includes receiving multiple neural network training configurations for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes training each of a group of neural network decoder/encoder pairs in accordance with the received training configurations. A method of wireless communication, by a base station, includes transmitting multiple neural network training configurations to a user equipment (UE) for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes receiving a neural network decoder/encoder pair trained in accordance with the training configurations.

摘要： Methods, systems, and devices for wireless communications are described. A receiving device (such as a user equipment (UE)) may receive a downlink grant including an indication to report a first channel state information and a second grant including an indication to report a second channel state information. In some cases, the second grant may be received after the downlink grant. The UE may determine a transmission order associated with the first channel state information and the second channel state information based on a configuration, and may transmit the first channel state information and the second channel state information according to the transmission order.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a plurality of bandwidth parts (BWPs) in a frequency band, wherein the configuration identifies a respective BWP-specific downlink (DL)-uplink (UL) pattern for each BWP of the plurality of BWPs, and wherein at least two of BWPs of the plurality of BWPs are configured with different BWP-specific DL-UL patterns and wherein each DL-UL pattern specifies which time intervals of a plurality of time intervals are dedicated to downlink and which time intervals of the plurality of time intervals are dedicated to uplink. The UE may communicate with the base station in one or more active BWPs of the plurality of BWPs using the respective BWP-specific DL-UL pattern for each of the one or more active BWPs. Numerous other aspects are described.

摘要： Techniques for supplementary sidelink resource configuration in full duplex mode may include a first user equipment (UE) transmitting to a base station an interference report indicating sidelink communication interference. The base station may select a resource pool according to the interference report, where the resource pool includes supplementary sidelink subchannels reserved for receiving sidelink communications and conditionally reserved for transmitting sidelink communications based on the interference report. The base station may transmit, to the first UE or a second UE causing the sidelink communication interference, configuration information indicating the resource pool. Based on the configuration information, the first UE and/or the second UE may perform sidelink communications (with each other or with other UEs) using the supplementary sidelink sub channels.
