Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a plurality of carriers in a cross-carrier scheduling scenario, whether a quantity of downlink control information (DCI) sizes for a set of DCIs that the UE monitors satisfies a threshold, wherein the threshold is a per scheduling cell per scheduled cell threshold or a per scheduled cell threshold. The UE may selectively perform a DCI size alignment procedure to adjust a DCI size configuration based at least in part on whether the quantity of DCI sizes satisfies the threshold. The UE may monitor for the set of DCIs based at least in part on the DCI size configuration. 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, for a secondary cell and a primary cell where cross-carrier scheduling is to occur from the secondary cell to the primary cell, whether a quantity of downlink control information (DCI) sizes for a set of DCIs that the UE monitors satisfies a threshold, wherein the threshold is a per scheduling cell per scheduled cell threshold or a per scheduled cell threshold. The UE may selectively perform a DCI size alignment procedure to adjust a DCI size configuration based at least in part on whether the quantity of DCI sizes satisfies the threshold. The UE may monitor for the set of DCIs based at least in part on the DCI size configuration. Numerous other aspects are provided.

Abstract: In a communication between a user equipment (UE) and a network node, the UE may receive a grant of uplink (UL) shared channel (SCH) resources from the network node. Each of the UL SCH resources may be associated with one of a plurality of hybrid automatic repeat request (HARQ) processes. Each HARQ process may be at least one of a plurality of HARQ process types, and each HARQ process type may be based on HARQ feedback status and HARQ retransmission status. The UE may transmit a control message on one or more UL SCH resources in response to the one or more UL SCH resources being determined to be usable based on the HARQ process type of the HARQ processes associated with the one or more of the UL SCH resources.

Abstract: Methods, systems, and devices for wireless communications are described for configuring contention-free uplink resources and contention-based uplink resources as preconfigured uplink resources (PUR) available for a user equipment (UE) to transmit one or more uplink transmissions without a specific allocation for the uplink transmission from a base station. Each of two or more UEs may be configured with separate portions of contention-free PUR that each UE may use to transmit a relatively small first uplink communication that provides an indication that the UE will transmit a relatively larger second uplink communication using contention-based PUR. The UE may transmit a buffer status report (B SR) using the contention-free PUR. The first communication may provide an indication of one or more physical layer parameters associated with the second uplink communication. The UE may transmit the second uplink communication using the indicated one or more physical layer parameters via the contention-based uplink resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive downlink control information (DCI) that schedules a first communication on a first bandwidth part and a second communication on a second bandwidth part; determine one or more parameters for the first bandwidth part and the second bandwidth part based at least in part on the DCI and in accordance with a bandwidth part configuration for a virtual bandwidth part; and perform the first communication and the second communication based at least in part on the one or more parameters. Numerous other aspects are provided.

Abstract: Techniques for reference signaling related to transmission power controls for communication devices are discussed and provided. A user equipment (UE) receives one or more sounding reference signal (SRS) transmission power control (TPC) configuration for uplink carriers. The SRS TPC configuration can comprise a mapping from one uplink carrier to one or more component carrier sets. The UE receives, from a monitoring cell, a downlink control information (DCI) comprising a request for SRS transmission on uplink carrier(s) and/or TPC command(s) for SRS transmission on the uplink carrier(s). The UE determines uplink carrier(s) corresponding to the SRS request and/or the TPC command(s) at least based on a correspondence between the SRS TPC configurations and the one or more uplink carriers or based on starting bit information.

Abstract: A method of wireless communication by a user equipment (UE) calculates a propagation delay for sending a message from the UE to a network node, such as a base station, via non-terrestrial communications. The method sends a random access preamble to the base station while accounting for the calculated propagation delay. The method starts a random access response (RAR) window at a first physical downlink control channel (PDCCH) occasion after twice the calculated propagation delay from sending the random access preamble. The method receives a random access response (RAR) message from the base station during the RAR window. The RAR message includes an uplink grant indicating an uplink shared channel resource. Further, the method sends an uplink message to arrive during the uplink shared channel resource while accounting for the calculated propagation delay.

Abstract: Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a notification of a change to multicast broadcast (MB) control information associated with at least one MB service to which the UE is subscribed, the MB control information being included in an MB control channel (MBCCH) scheduled by a physical downlink control channel (PDCCH) communication addressed to an MB radio network temporary identifier (MB-RNTI); and monitor one or more resources of the MBCCH to receive updated MB control information based at least in part on receiving the notification of the change to the MB control information. Numerous other aspects are provided.

Abstract: A base station may transmit a broadcast/multicast service in a multicast broadcast single frequency network (MBSFN) area multicast communication. A method of wireless communication at a base station in accordance with an aspect of the present disclosure comprises determining a broadcast/multicast service to be provided to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) area, and transmitting a tracking reference signal (TRS) to the UE, the TRS indicating information associated with receiving the broadcast/multicast service by the UE.
