Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a synchronization signal block (SSB) from a plurality of SSBs received from a base station based at least in part on a power measurement associated with the SSB. The UE may determine a physical random access channel (PRACH) coverage enhancement (CE) level that is associated with the SSB. The UE may perform, with the base station, a PRACH transmission on PRACH resources associated with the SSB and the PRACH CE level. Numerous other aspects are provided.

Abstract: A method for wireless communication performed by a user equipment (UE) includes transmitting, to a base station, an indication comprising a per slot capability for a first number of physical downlink control channel (PDCCH) blind decodes and a first number of control channel elements (CCEs). The method also includes receiving, from the base station, a search space configuration based on the indication. The search space configuration configures a second number of blind decodes per slot, a second number of CCEs per slot, and a PDCCH monitoring periodicity. The method also includes decoding a PDCCH based on the search space configuration.

Abstract: This disclosure provides methods, devices and systems for harvesting radio frequency (RF) energy based on an energy harvesting EH indication signal. A transmitting device such as a base station may transmit, to a user equipment (UE), an EH indication signal that indicates a time period when radio frequency (RF) energy is to be available. The UE may receive the EH indication signal and harvest RF energy from the RF signal during the time period. The transmitting device may transmit an RF signal to the UE or another UE during the time period. The UE may receive a wake up indication indicating a second time period to monitor a control channel. The UE may split power between energy harvesting and receiving RF signals during the second time period.

Abstract: A user equipment (UE) in a radio resource connection (RRC) inactive or idle state may initiate a random access procedure with a base station (BS) for initial access to a network, to resume an RRC connection, to re-establish an RRC connection, or to perform an early data transmission to a network. The BS may selectively include a timing advance (TA) medium access control (MAC) control element (CE) and an indication of a simplified timing advance command for the UE. The aspects herein may reduce the signaling overhead of the TA MAC CE. For example, the UE may enter an idle state or an inactive state. The UE may transmit a random access message to the BS with a request for timing advance simplification based, at least in part, on a TA value corresponding to the BS, wherein the TA value is applied to the transmission of the random access message.

Abstract: A configuration of cross-carrier channel state information (CSI) reporting is disclosed. A user equipment (UE) may be configured for CSI reporting, which includes multiple trigger states, in which some of these trigger states include at least one carrier indicator identifying at least one component carrier (CC) for CSI measurement. Upon receipt of a downlink control information (DCI) message including identification of one of the trigger states, the UE identifies at least one CSI report configuration which may be identified with an associated CC and identification of at least one CSI resource setting identified with the CC for each of the CSI report configurations. The UE may then perform CSI measurement for the identified CC based on the CSI report configuration and resource setting. The UE may then signal the CSI report, including the CSI measurement, to a serving base station.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless devices may support a prediction capability for prediction-based control information. A first device may receive, from a second device, first control signaling that activates the predication capability of the first device to generate a set of one or more control parameters for communications. The second device may transmit second control signaling to the first device to indicate initial values of the control parameters and a channel condition model for the first device. The first device and the second device may generate a set of multiple values associated with the control parameters over a time period based on the initial values of the control parameters and the channel condition model. The first device and the second device may communicate during at least the time period according to the set of generated values associated with the control parameters.

Abstract: A UE receives DCI in a PDCCH, the DCI triggers reception of AP CSI-RS, and the PDCCH has a first numerology and the AP CSI-RS has a second numerology. The UE determines, when a CORESET is configured on an active BWP of a serving cell for receiving the AP CSI-RS and when the first numerology is the same as the second numerology, a default AP CSI-RS beam for receiving the AP CSI-RS based on a beam used for receiving the CORESET with a lowest ID in a latest monitored slot of the active BWP of the serving cell. The UE determines, otherwise when the first numerology is the same as the second numerology, the default AP CSI-RS beam for receiving the AP CSI-RS based on a QCL assumption of a PDSCH TCI state with a lowest ID on the active BWP of the serving cell for receiving the AP CSI-RS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may connect with a base station over a set of component carriers according to a carrier aggregation configuration. The UE may then monitor a search space configured for scheduling multiple component carriers and may receive downlink control information (DCI) based on monitoring the search space. The DCI may include a carrier indicator field (CIF) and may schedule a set of data transmissions over two or more component carriers (e.g., from the set of component carriers). The UE may determine that the two or more component carriers include the first component carrier and the second component carrier based on the monitored search space, the CIF within the DCI, or both. The UE may then transmit and receive the set of data transmissions over the first and second component carriers.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for grouping common DCI for CLI measurement and reporting. In a first aspect, a UE may receive DCI that is common to a group of UEs that includes the UE. The DCI may be configured to trigger at least one of an SRS transmission or a CLI measurement. The UE may transmit the SRS transmission and/or report the CLI measurement based on the DCI that is common to the group of UEs. In a second aspect, a base station may transmit at least one DCI that is common to the group of UEs to trigger the at least one of the SRS transmission or the CLI report for the group of UEs. The base station may receive the CLI report from at least a subset of UEs in the group of UEs.
