Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a set of resources for one or more synchronization signal blocks (SSBs) associated with one or more pseudo-random sequences. The one or more pseudo-random sequences and the set of resources may be indicated by an output of a pseudo-random function (PRF) that is based on a timing parameter, a cell identifier, and a key. In some examples, the UE may monitor a set of resources within a control resource set for a downlink control channel, where the set of resources for the downlink control channel is based on an output of the PRF. The UE communicate with a network entity via a cell associated with the cell identifier based on the monitoring.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication for a first radio access technology (RAT) has been dynamically scheduled or semi-statically configured, wherein the UE is in a dual connectivity mode using the first RAT and a second RAT. The UE may identify an uplink subframe for transmission of the uplink communication based at least in part on whether the uplink communication has been dynamically scheduled or semi-statically configured, and based at least in part on a downlink-reference uplink-downlink configuration. The UE may transmit the uplink communication in the identified uplink subframe. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that transmission of one or more first messages, to a wireless device and via a first radio access technology (RAT), does not meet a transmission quality threshold associated with the one or more first messages, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT. The UE may adjust a prioritization of the one or more first messages or the one or more second messages to prioritize the transmission of the one or more first messages over the one or more second messages. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses that support channel state information (CSI) reporting techniques for secondary cell (SCell) activation. A user equipment (UE) may receive one or more medium access control-control elements (MAC-CEs) that indicate a secondary cell (SCell) activation command, an aperiodic tracking reference signal (AP-TRS) trigger, and an aperiodic channel state information (AP-CSI) report trigger. The network entity may signal the SCell activation command, the AP-TRS trigger, and the AP-CSI report trigger in the same MAC-CE or in separate MAC-CEs. The UE may receive and measure AP-TRS in accordance with the AP-TRS trigger indicated by the one or more MAC-CEs, and may perform measurements via an aperiodic channel measurement resource (AP-CMR) and an aperiodic interference measurement resource (AP-IMR) in accordance with the AP-CSI report trigger indicated by the one or more MAC-CEs. Accordingly, the UE may transmit an AP-CSI report associated with the measurements.

Abstract: Certain aspects are directed to a user equipment (UE) configured to receive reference signals from a network node via multiple resource element groups (REGs) including at least one REG carrying a downlink transmission. In some examples, the UE may be configured to receive, from the network node, communication parameters for a downlink transmission, the communication parameters indicative of a first resource element group (REG) bundle and a second REG bundle. In some examples, the UE may receive the downlink transmission via the first REG bundle. In some examples, the UE may be configured to perform channel estimation of the downlink transmission based on reference signals transmitted via the first REG bundle and the second REG bundle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a set of resource elements for Long Term Evolution (LTE) cell-specific reference signal (LTE-CRS) interference measurements associated with one or more neighboring LTE cells. The UE may perform the LTE-CRS interference measurements on the set of resource elements. The UE may transmit, to the base station, an interference measurement indication based at least in part on the LTE-CRS interference measurements. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource configuration for communications with a base station on a multiple sets of resources across multiple component carriers, the resource configuration including at least a first set of resources on a first component carrier and a second set of resources on a second component carrier. The UE may receive, from the base station, a downlink control information (DCI) message on the first component carrier, the DCI message including a DCI format that controls the multiple of sets of resources across the plurality of component carriers. The UE may determine that the first set of resources and the second set of resources are one of activated or released based on a first indication in the DCI message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may selectively determine to decode a downlink shared channel multicast transmission based on whether the downlink shared channel includes a retransmission of an initial multicast transmission. A base station may transmit a message in a downlink control channel to indicate if the downlink shared channel is carrying the retransmission of the initial multicast transmission. For example, the base station may transmit a group random network temporary identifier, downlink control information with a retransmission indicator bit, or both to indicate if the downlink shared channel is carrying the retransmission. In some cases, the message in the downlink control channel may be received at a layer one (L1) of the UE, and the downlink shared channel transmission may be decoded at L1 of the UE and sent to a layer two (L2) of the UE for processing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a search space associated with a physical downlink control channel (PDCCH) corresponding to a multicast/broadcast (MBS) physical downlink shared channel (PDSCH) for at least one MBS PDCCH communication having a payload that is scrambled according to a PDCCH payload scrambling sequence based on a value of a radio network temporary identifier (RNTI), wherein the value of the RNTI is equal to a group-RNTI (G-RNTI) or zero. The UE may receive the at least one MBS PDCCH communication. Numerous other aspects are described.

Abstract: A base station may transmit downlink control information messages (DCIs) that schedule multiple physical downlink shared channels (PDSCHs) in a single DCI (multi-PDSCH DCIs) to a UE. The base station may generate DCIs with multiple downlink association index (DAI) bitwidths. The base station generate a given DCI with a DAI bitwidth based on a DCI format of the DCI, based on whether the DCI is a multi-PDSCH DCI, based on a carrier that the DCI is transmitted on, or whether the base station is capable of scheduling the UE with multi-PDSCH DCIs in general. The UE may determine the DAI bitwidth of received DCIs and may determine whether any DCIs were missed based on the DAI and the bitwidth of the DAI.
