Methods, systems, and devices for wireless communications are described. Wireless communications systems may support implementation of narrow bandwidth parts (NBWPs). For example, a NBWP may be established over a reduced bandwidth to support user equipment (UEs) with reduced complexity features (e.g., such as UEs with reduced bandwidth capabilities). Wireless communications systems may provide for UE transitioning to a NBWP (e.g., after initial cell search), as well as for UE transitioning amongst NBWPs (e.g., subsequent transitions to other NBWPs after an initial transition to a NBWP after initial cell search). For example, a UE may initially transition to a NBWP (e.g., transition to monitor the NBWP for reference signals or to utilize the NBWP for uplink/downlink communications) to support reduced bandwidth capabilities of the UE. Subsequently, the UE may transition amongst other NBWPs for network load balancing, UE frequency hopping gain, etc.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may decode a downlink communication on a physical downlink shared channel (PDSCH). The downlink communication may have punctured resources. The UE may transmit, in association with the downlink communication, a first uplink communication on a physical uplink shared channel (PUSCH), and measure self-interference in the punctured resources of the downlink communication on the PDSCH that are within a threshold distance of resources of the first uplink communication on the PUSCH. Numerous other aspects are provided.

The disclosure includes embodiments for asynchronous observation matching for object localization in connected vehicles. A method includes receiving a wireless message from the remote connected vehicle. The wireless message includes first observation data recorded by the remote connected vehicle and describing sensor measurements of the remote connected vehicle at a first time but not a second time. The method includes analyzing a set of vectors describing how a known object moves within a two-dimensional space to determine a two-dimensional flow of the known object in the two-dimensional space during a timespan. The method includes analyzing the two-dimensional flow of the object to infer a three-dimensional flow of the object in a three-dimensional space during the timespan. The method includes estimating second observation data recoded by the remote connected vehicle at the second time so that the impact of the latency is modified.

Apparatus and methods for operating multiple link premises devices in a wireless network. In one embodiment, premises devices such as a wireless gateway, Access Point (AP) or user devices use Wireless Local Area Network (WLAN) technology for the transmission of data on multiple links operating on different frequencies. The disclosed apparatus and methods provide a solution to share channel statistic or similar data across the different links, such as for link performance improvement via more optimal MIMO operation. In one implementation, large-scale channel statistics are shared via the pre-amble or mid-amble of a frame across multiple links between an AP and a user device to enhance receiver performance. In another embodiment, the channel statistics are shared between multiple AP devices which can coordinate with each other, and/or are made specific to individual client devices, in order to enhance receiver performance.

Methods and systems for adjusting reference signal reporting based on path loss and fading and cell edge conditions experienced by wireless devices in 5G EN-DC networks. As the path loss increases, a period between reference signal reports (or a frequency of reference signal reports) can be increased. This ensures continued quality of service for the wireless devices. Reference signals can include SRS, DMRS, PTRS, etc.
