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 communications are described. The described techniques relate to an early indication, from a base station to a user equipment (UE), that may allow the UE to determine from the first symbol of a synchronization signal block (SSB) if the system information associated with the SSB is intended for the UE. Thus, when the UE receives the indication that the system information is dedicated to the UE, the UE may determine to receive and decode the remaining synchronization signal block, a master information block, a set of control resources, a downlink control channel, and a downlink shared channel to receive the system information. In some cases, the UE may determine that the system information is generic and end decoding during reception of the SSB to conserve computational resources by avoiding unnecessary decoding.

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: 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: Configurations and feedback schemes for compressed channel state information (CSI) feedback are provided. A User Equipment (UE) determines a constraint on a total number of transfer domain coefficients to be reported for compressed Channel State Information (CSI) feedback by the UE for a plurality of beams identified for the feedback, wherein each transfer domain coefficient is associated with amplitude information and phase information. The UE selects from a transfer domain coefficient compression matrix, based on the constraint, a set of one or more transfer domain coefficients to report for each of the beams. The UE reports information indicating a number of selected transfer domain coefficients in the set of transfer domain coefficients for each beam and a location of each transfer domain coefficient within the transfer domain coefficient compression matrix and reports at least the amplitude and phase information for the selected coefficients.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) for multiple transmission reception point (multi-TRP) transmission such as non-coherent joint transmission (NCJT), including determining subband sizes for CSI and rules for Part II CSI omission. A method that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration associated with one or more CSI reference signal (RS) resources, each CSI resource including a set of ports or port groups. The UE selects one or more CSI-RS resources for which to report CSI and determines a subband size for sending a CSI report based, at least in part, on payload of the CSI report. In an example method, the UE can determine whether the UE has sufficient resources for the CSI report and omit at least a portion of the CSI based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a device may select antenna elements from a planar array to transmit or receive an orbital angular momentum (OAM) beam. The device may determine a first area (e.g., a first ring area) based on an angular direction over which the device can communicate an OAM beam with a second device and may determine a second area (e.g., a second ring area) on the planar array based on projecting the first area on the planar array. The device may select a set of antenna elements from the planar array that are located within the second area. The device may determine a complex-valued weight for each antenna element of the selected set of antenna elements and may transmit or receive an OAM beam to or from the second device via the set of antenna elements according to the angular direction.
