Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, at least one of a first downlink control information (DCI) or a second DCI, each DCI indicating at least one of one or more sets of one or more frequency domain (FD) bases and linear combination coefficients and transmit a PUSCH with subband precoding determined based on the first DCI, the second DCI, or a combination of the first and second DCI, depending on whether the first DCI is received, the second DCI is received, or both the first and second DCI are received.

Abstract: Disclosed are techniques related to wireless communication system to enable full duplex communication. A network node may include a transceiver, a memory, and a processor communicatively coupled to the transceiver and the memory. The transceiver, memory, and processor may be configured to determine downlink (DL) parent and child link priorities for parent and child time-domain resources that overlap in time at least partially. The transceiver, memory, and processor may also be configured to determine DL parent and child beams based on the DL parent and child link priorities. The transceiver, memory, and processor may further be configured to notify the parent node of the DL parent beam for the parent and child time-domain resources. The transceiver, memory, and processor may yet further be configured to concurrently receive parent traffic from the parent node using the DL parent beam and transmit child traffic to the child node using the DL child beam.

Abstract: Aspects described herein relate to transmitting an indication of a capability to support concurrent or time division multiplexed uplink transmission of at least one of multiple uplink channels across multiple component carriers. In addition, a configuration to transmit over the at least one of the multiple uplink channels over the multiple component carriers using concurrent transmission or time division multiplexed transmission can be received based on the indication.

Abstract: The frequency domain basis may be fed back in a CSI report from a user equipment (UE), with extra overhead and computation cost. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive, from a base station, CSI reference signals (CSI-RS). The apparatus may be further configured to receive, from the base station, a configuration including a frequency domain basis restriction indicating a frequency domain basis subset, where the frequency domain basis subset is selected from a frequency domain basis set. The apparatus may be configured to prepare, upon receiving the frequency domain basis restriction, a CSI report based on the CSI-RS and the frequency domain basis subset. The apparatus may be further configured to transmit the CSI report to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for performing periodic and aperiodic CSI reporting for MIMO operations. According to certain aspects, operations for performing periodic and aperiodic CSI reporting for MIMO generally includes configuring a user equipment (UE) that is capable of MIMO with different parameters for periodic and aperiodic channel state information (CSI) reporting, wherein the different parameters indicate at least one of what resources to measure or what information to report, and receiving periodic and aperiodic CSI reporting from the UE according to the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A full duplex user equipment (UE) may provide a channel state information (CSI) report to abase station to enable the base station to schedule simultaneous uplink and downlink communications for the full duplex UE. For example, the base station may transmit a CSI report configuration to the UE that indicates for the UE to report a full duplex CSI. In some cases, the CSI report configuration may include the UE to report CSI under a full duplex mode with or without an indication of an uplink bandwidth. Accordingly, the UE may calculate and report the self-full duplex mode CSI to the base station according to the received configuration. The base station may then determine a radio resource allocation and transport format for downlink data transfer and for uplink data transfer under the full duplex mode.

Abstract: Methods, systems, and devices for wireless communications are described. A frame, scheduling instance, scheduling period etc. may include a set of downlink subframes and a set of uplink subframes. At least one control message transmitted in a downlink subframe may schedule a set of data messages in the downlink subframes of the frame. The downlink subframe may also include data messages scheduled by a control message of a previous frame. Further, feedback timings for data messages of the frame may be determined based on the corresponding control messages (e.g., from the current frame and the previous frame). Feedback responses corresponding to the data messages may be transmitted in a bundled manner in the set of uplink subframes. Using this cross-frame scheduling technique, the resources of a frame may be efficiently utilized.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an indication of a first transmit power configuration and a second transmit power configuration for a physical uplink shared channel (PUSCH) communication. The wireless communication device may transmit, using a first transmit power that is based at least in part on the first transmit power configuration, a first portion of the PUSCH communication in a full-duplex portion of a time-frequency resource. The wireless communication device may transmit, using a second transmit power that is based at least in part on the second transmit power configuration, a second portion of the PUSCH communication in a non-full-duplex portion of the time-frequency resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), a first signaling communication that configures a plurality of transmit precoder matrix indicator (TPMI) and sounding reference signal (SRS) resource indicator (SRI) pairs. The plurality of TPMI and SRI pairs may be for transmitting respective physical uplink shared channel (PUSCH) communications to the BS. The UE may receive, from the BS, a second signaling communication that indicates an update to a TPMI and SRI pair of the plurality of TPMI and SRI pairs. The UE may transmit, to the BS, a PUSCH communication, of the respective PUSCH communications, based at least in part on the update to the TPMI and SRI pair. Numerous other aspects are provided.
