Abstract: Enhancement of uplink transmissions with survival time or delay sensitive data is discussed. A set of time sensitive resources is preconfigured for one or more user equipment (UEs). A serving base station communicates an identification of the configured time sensitive resources to the UEs. Upon detection of time sensitive data for transmission, a UE may send a time sensitive scheduling request to the base station that indicates the UE will be transmitting time sensitive data on the configured resources. When shared amount multiple UEs, the serving base station may send availability signals to the other UEs when the configured time sensitive resources are being used by another UE and when the configured resources are available again. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may In support multiple component carriers that may be used to transmit uplink transmissions. One carrier may be used at a time such that the may switch between the carriers based on an uplink transmission schedule. In some cases, switching may be limited by a consecutive uplink switching rule or UE capability. In some cases, the gap between two consecutive uplink carrier switching operations may be limited to a resource (e.g., slot, symbol), such that the UE may expect to perform at most one switching operation per resource. In some implementations, the gap between two consecutive uplink carrier switching operations may be limited to a duration (e. g., 14 symbols, 4 symbols), such that the UE may expect to perform at most one switching operation per a duration less than or equal to a threshold.

Abstract: Methods, systems, and devices for wireless communications are described. Feedback based codebooks for reducing or eliminating interference between orbital angular momentum (OAM) based backhaul communications between a first network node and a second network node and access communications between the first network node and a user equipment (UE) are described. The first network node may transmit a message to a UE indicating a feedback codebook for a set of reference signals associated with OAM modes. The first network node may transmit the reference signals, where each reference signals may be associated with a respective OAM mode. The UE may generate and indicate in a feedback report to the first network node codewords corresponding to UE feedback for the received reference signals. The first network node may communicate with the UE via an access link and with the second network node via a backhaul link based on the feedback report.

Abstract: Certain aspects of the present disclosure provide techniques for identifying measurement occasions (MOs) to monitor and refrain from monitoring for a repetition of a downlink channel. An example method generally includes determining that, within a monitoring occasion (MO) duration associated with decoding a number of physical downlink control channel (PDCCH) repetitions, the UE should refrain from monitoring at least one MO associated with a first control resource set (CORESET), wherein the MO duration comprises multiple MOs in which the UE is to monitor for repeated PDCCH candidates; refraining from monitoring a first subset of MOs in the MO duration, based on the determination; and monitoring a second subset of MOs within the MO duration.

Abstract: Methods, systems, and devices for wireless communication are described to support reducing a time domain selectivity of a downlink channel with multiple signal paths. A base station may spatially precode multiple channel state information reference signals (CSI-RSs) and transmit the spatially precoded CSI-RSs to a user equipment (UE), where at least one spatially precoded CSI-RS may correspond to each signal path. Based on the spatially precoded CSI-RSs, the UE may determine a mean or average Doppler shift for each signal path. The UE may transmit, to the base station, signaling indicative of the respective average Doppler shifts for each signal path. Based on the indication of the Doppler shifts, the base station may spatially and temporally precode one or more downlink transmissions to the UE, which may reduce the time domain selectivity of the downlink channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration for processing a data block into an unencoded uplink signal. The UE may determine pre-equalization parameters corresponding to the unencoded uplink signal based on the indication of the configuration. The UE may apply analog modulation and the pre-equalization parameters to the data block to form the unencoded uplink signal and transmit the unencoded uplink signal on overlapping time-frequency resources with one or more other UEs according to an over the air computation operation. The UE may determine a plurality of channel inversion coefficients based on the indication of the configuration for processing the data block into the unencoded uplink signal, measuring one or more reference signals, receiving an indication of an inversion granularity, receiving an inversion coefficient power threshold, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication.

Abstract: A low complexity user equipment (UE) may be in communication with another UE (e.g., with a premium UE or more capable UE) via a device-to-device communication link (e.g., via sidelink), and the low complexity UE may leverage the device-to-device link to improve (e.g., simplify, expedite, etc.) random access procedures performed by the low complexity UE. For example, a low complexity UE may request contention free random access (CFRA) resources via the device-to-device link with another UE. Another device (e.g., another UE in device-to-device communication with the low complexity UE) may receive the request from the low complexity UE and forward the request to the network (e.g., to a base station). The network may then configure CFRA resources for the low complexity UE. Upon receiving the CFRA configuration, the low complexity UE may perform a random access procedure (e.g., a CFRA procedure) with the network (e.g., with the base station) accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.
