Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may modify the contents of a channel state information (CSI) report based on delaying transmission of the CSI report. For example, a base station may transmit one or more downlink messages to the UE from which the UE may generate CSI. The UE may delay transmitting a CSI report that includes the CSI report one or more times, for example, due to a collision between a semi-persistent scheduling (SPS) scheme and a time division duplexing (TDD) scheme according to which the UE and the base station communicate. Based on a quantity of occasions that the UE delays transmission of the CSI report, the UE may modify the CSI included in the CSI report and transmit the CSI report including the modified CSI to the base station.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for dynamically triggering or skipping channel state feedback (CSF). A method that may be performed by a user equipment (UE) includes receiving, from a network entity, a configuration indicating CSF reporting occasions, receiving a downlink (DL) transmission, and transmitting CSF on only some CSF reporting occasions after receiving the DL transmission when one or more trigger conditions are met. According to certain aspects, when one or more trigger conditions are not met, the UE skips at least some CSF reporting occasions.

Abstract: A base station may transmit a set of CSI-RSs corresponding to a set of ports of a UE and the UE may perform a set of CQI measurements on each port and across each sub-band. The UE may select, for each CSI-RS resource that the UE measures, a set of M worst CQIs and may select a best CSI-RS resource based at least in part on a corresponding set of M worst CQIs for the CSI-RS resource. The UE may report the M worst CQIs for the selected CSI-RS resource. Alternatively, the UE may select, for each CSI-RS resource that the UE measures, a set of M worst CQIs and may select a worst CSI-RS resource. In this way, the UE enables the base station to select a DMRS port and/or an MCS to use for communication.

Abstract: A communication device receives, from another communication device, a set of transmissions over a sidelink shared channel, or over a downlink shared channel (1005). The communication device estimates a Doppler spread or a delay spread based on the received set of transmissions over the shared channel (1010). The communication device selects a reference signal configuration, from multiple reference signal configurations, based on the estimated Doppler spread or the estimated delay spread (1015). The reference signal is a DMRS, a PTRS and/or a TRS. Finally, the communication device transmits feedback indicating the selected reference signal configuration for a subsequent set of transmissions over the shared channel (1020).

For a set of scheduled transmission instances of a data communication, a transmitting network node may determine a first spatial filter to apply for a first subset of the scheduled transmission instances configured to provide the data communication and a second spatial filter to apply for a second subset of the scheduled transmission instances configured to allow energy harvesting at an energy harvesting device. In some cases, the transmitting network node may indicate a first quasi co-location (QCL) relation to use for the first subset of the scheduled transmission instances configured to provide the data communication to the network node receiving the data transmissions, and the transmitting network node may indicate a second QCL relation to use for the second subset of the scheduled transmission instances configured to allow energy harvesting to the energy harvesting device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message from a base station indicating a configuration of an uplink waveform for full-duplex communications at the UE. The UE may receive an additional control message scheduling a set of uplink resources and a set of downlink resources for the full-duplex communications. The set of uplink resources and the set of downlink resources may at least partially overlap in a time-domain. A frequency-domain gap between the set of uplink resources and the set of downlink resources may be based on the first uplink waveform and a first downlink waveform used by the base station. The UE may communicate with the base station on the set of uplink resources and the set of downlink resources in accordance with the frequency-domain gap.

Abstract: Some techniques described herein provide autonomous modification of a modulation and coding scheme (MCS) of a grant for a transmission by a user equipment UE. For example, the UE may receive a grant (e.g., a configured grant) indicating a resource allocation and a first MCS for a transmission on the resource allocation. The UE may use the resource allocation for a transmission of a number of transport blocks (e.g., one or more transport blocks), and may use a second MCS, different than the first MCS, for the transmission. In some examples, the second MCS may be a lower MCS, associated with a lower modulation scheme and/or code rate, than the first MCS. Thus, a per-resource-block power consumption of the transmission is decreased by using the second MCS, which provides power savings while reducing or eliminating padding of the uplink communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, control information indicating of a first set of occasions for periodic transmissions and a second set of occasions for periodic transmissions, where an occasion of the first set of occasions is mapped to one or more occasions of the second set of occasions. The UE may transmit a first message during the first set of occasions, receive a feedback message indicating a failure of the first message to be received during the first set of occasions, and transmit a retransmission of the first message on one or more occasions of the second set of occasions. The transmission may be based on the feedback message and in accordance with the mapping between the first set of occasions and the second set of occasions.

The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.
