Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network node may transmit a control message to a first UE that indicates one or more candidate precoding matrices associated with uplink precoding at a second UE. The first UE may receive a CSI-reference signal (CSI-RS) associated with estimation of a channel between the first UE and the network node and may receive a CLI-reference signal (CLI-RS) associated with estimation of a CLI channel between the first UE and the second UE. The bandwidth of the CLI-RS may be based on a measurement rule. The first UE may generate CSI based on the CSI-RS, the CLI channel, and one or more of the candidate precoding matrices and transmit a CSI report including the CSI.

Abstract: Aspects relate to wireless communications utilizing cross carrier scheduling Methods and apparatus include generating at least one slot in a control channel from a scheduling cell, the at least one slot including a plurality of control channel segments such as PDCCH segments, which are arranged at respective times within the at least one slot. Each of the control channel segments includes control information such as DCIs corresponding to respective slots for a scheduled cell. Distributing the control channel information in segments or spans over time affords improved decoding timing in a UE in the scheduled cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust a transmission parameter, associated with an uplink transmission from the UE, such that a phase for the uplink transmission is continuous across symbols of the uplink transmission. Adjusting the transmission parameter includes at least one of: rate-matching, puncturing, or power scaling one or more of the symbols within the uplink transmission, modifying at least one of a modulation and coding scheme or a power associated with a downlink transmission to the UE, or a combination thereof. The UE may further transmit, to a base station, the uplink transmission based at least in part on adjusting the transmission parameter. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may obtain information indicative of a configuration to provide code block group (CBG)-based feedback for one or more semi-persistent scheduling (SPS) communications scheduled for the first device. The first device may then monitor for the one or more SPS communications in one or more CBGs of a TB in accordance with one or more SPS communication configurations. Based on the monitoring of the semi-persistent scheduling communications, the first device may generate one or more feedback bits associated with the one or more SPS communications, and may communicate, with a second device, the one or more feedback bits associated with the one or more SPS communications in accordance with the configuration to provide CBG-based feedback.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a UE may report channel state feedback (CSF) to a network entity based on channel state information (CSI) measurements and CLI measurements. In another aspect, a UE may explicitly report CLI measurements to a network entity. In yet another aspect, a UE may report a signal-to-interference-plus-noise ratio (SINR) to a network entity based on CLI measurements, and the network entity may trigger the UE to perform further CLI measurements on signals received from other UEs based on the SINR. In yet another aspect, a UE may generate a report using CLI measurements based on whether the UE is allocated enough time to generate and transmit the report. In yet another aspect, a UE may identify a suitable priority for reporting CLI to a network entity.

Abstract: Rate-matching and channel estimation are disclosed for new radio (NR) user equipments (UEs). In one aspect, a method of wireless communication includes obtaining coexistence information associated with neighboring wireless operations according to a legacy radio access technology (RAT) coexisting with a new radio (NR) RAT. The coexistence information includes a number of ports associated with reference signals of the legacy RAT, a frequency pattern of the reference signals of the legacy RAT, and a subframe type of corresponding subframes of the legacy RAT with transmission segments of the NR RAT. The method also includes determining one or more reference signal occasions of the legacy RAT coinciding with a shared downlink direction communication for the NR RAT and legacy RAT. The method further includes rate-matching reception of NR downlink transmissions within the shared downlink direction communication around the one or more reference signal occasions. Other aspects are described and claimed.

Abstract: Techniques are described for supporting user equipment (UE) positioning in a non-terrestrial network (NTN). To allow calculating a position/location of a UE based on reference signal (RS) measurements to and from one satellite (or a terrestrial base station), a device may be configured to calculate a doppler measurement and a range measurement and report such measurements to be used by a location server to calculate a UE position. An example device may receive a first RS (with the first RS being one of a positioning reference signal (PRS) or a sounding reference signal (SRS)), receive a second RS associated with the first RS, calculate a doppler measurement based on one or both of the first RS or the second RS, and report the doppler measurement. The doppler measurement (such as a measured frequency offset) may be used by a location server to calculate a UE position on the earth surface.
