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. 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 communicate with a base station over a first bandwidth part (BWP) of a carrier. The UE may receive a beam failure recovery (BFR) configuration signal configuring a set of periodic channel state information reference signals (CSI-RSs) in the first BWP and a set of synchronization signals in a second BWP. The UE may measure the set of periodic CSI-RSs in the first BWP. The UE may set a beam for communicating with the base station over the first BWP based at least in part on the measuring. The UE may be a reduced bandwidth capability and support communicating with the base station using only one BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit a first set of periodic signals associated with a first set of spatial relationships in a first set of periodic signal transmission occasions associated with a first periodicity; and transmit one or more second sets of periodic signals with a second set of spatial relationships in one or more second sets of periodic signal transmission occasions associated with a second periodicity, wherein the one or more second sets of periodic signal transmission occasions occur before a next first set of the periodic signal transmission occasions. Numerous other aspects are provided.

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 first device may select, from multiple orbital angular momentum (OAM) modes, a set of one or more primary OAM modes and a set of one or more secondary OAM modes, where at least one primary OAM mode is activated periodically and at least one secondary OAM mode is activated based on a trigger. The first device may transmit, to a second device, a message indicating a configuration for the selected set of one or more primary OAM modes, the selected set of one or more secondary OAM modes, and discontinuous reception (DRX) parameters for each of the sets of OAM modes. The second device may monitor for a signal using a primary OAM mode using the DRX parameters for the set of primary OAM modes, and the second device may activate a second OAM mode based on receiving the signal.

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.
