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: 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.

Abstract: A method, an apparatus, a base station, a user equipment (UE), and a computer program product for wireless communication are provided. The base station may encode a wakeup signal so that a preamble of the wakeup signal indicates whether the wakeup signal is relevant to the UE. The UE may select a technique for detecting the wakeup signal based at least in part on a partial, full, or no synchronization. In some aspects, the wakeup signal may be encoded with a system frame number. In some aspects, wakeup signals for guardband/standalone UEs are provided. 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 signal, to a base station, a capability of the UE relating to carrier aggregation for a particular category or class of the UE, such as for narrowband Internet of Things (NB-IoT) UEs. The UE may receive, from the base station, a configuration for carrier aggregation for the particular category or class of the UE based at least in part on the capability of the UE relating to carrier aggregation for the particular category or class of the UE. The UE may communicate with the base station using carrier aggregation based at least in part on the configuration for carrier aggregation for the particular category or class of the UE. Numerous other aspects are provided.

Abstract: Some techniques and apparatuses described herein provide for the determination of a gap for a scheduled communication involving multiple, different TBs. For example, some techniques and apparatuses described herein provide for the determination of a gap between two or more PDSCHs that are scheduled by a same DCI based at least in part on a UE capability, such as a processing time or a processing mode. Some techniques and apparatuses described herein provide for the determination of a gap between a last PDSCH and a next PDCCH based at least in part on the UE capability. The gap(s) may permit the UE to successfully receive and/or decode multiple PDSCHs and/or PDCCHs in view of the limitations imposed by the UE's processing time or processing mode. In this way, efficiency of PDSCH/PDCCH resource utilization may be improved, the likelihood of a failed PDCCH transmission is reduced, and network efficiency is improved.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a User Equipment (UE). The UE receives a second random access message from the base station after transmitting a first random access message. The second random access message comprises a random access response (RAR) that indicates a narrowband to be used for receiving a fourth random access message. The apparatus determines whether to perform a measurement of the narrowband for the fourth random access message based on an amount of time between receiving the second random access message and transmitting a third random access message. The base station may determine whether the report comprises a measurement of the first narrowband or the second narrowband based on an amount of time between the second random access message and the third random access message or based on an indication in the third random access message.
