Abstract: Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.

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: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station and at the UE of a group of UEs, control signaling indicating a link between a first search space set and a second search space set used for a multicast broadcast service, where a first downlink control channel for the group of UEs is transmitted in the first search space set and a second downlink control channel is transmitted in the second search space set, monitoring the first search space set for a first instance of control information in the first downlink control channel and the second search space set for a second instance of the control information in the second downlink control channel, and decoding the first instance or the second instance of the control information, or both, based on the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use dynamic power aggregation techniques to perform instantaneous transmit power adjustments in an uplink carrier aggregation configuration. For example, the UE may dynamically adjust the instantaneous transmit power with network assistance. In some cases, the base station may configure a set of power aggregation parameters to control the instantaneous transmit power behavior of the UE. The UE may adjust the instantaneous transmit power in accordance with the power aggregation parameters. In some other cases, the base station may configure the UE to report one or more parameters. Based on the report, the base station may determine a power aggregation configuration for the UE in a time interval. In some other cases, the UE may be configured to scale the instantaneous transmit power for individual component carriers in the carrier aggregation configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first transmission including encoded bits of a data packet and a second transmission including some or all of the encoded bits of the data packet. The first transmission associated with a first limited buffer rate matching (LBRM) configuration and the second transmission may be associated with a second LBRM configuration. The UE may process the first transmission and the second transmission based on the first LBRM associated with the first transmission being different than the second LBRM associated with the second transmission.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE transmits a DSS capability indication to a network entity (e.g., base station), which determines scheduling information for resources of a DSS carrier based on the DSS capability indication. In another aspect, a BS transmits RAT-specific (e.g., LTE-specific) information associated with a DL RS (e.g., LTE CRS) to a UE, which processes the DL RS on a DSS carrier based at least in part on the RAT-specific information.

Abstract: Certain aspects of the present disclosure provide techniques for resource allocation and hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback for multi-cell scheduling. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a configuration for a plurality of carriers, receiving, from the BS, control information indicating whether resources for a data channel are allocated in a concatenated pair of carriers of the plurality of carriers, and communicating on the data channel with the BS based on the control information.

Abstract: In embodiments of systems and methods for managing control signaling for multicast communications, a base station may transmit to a wireless device an indication of whether to monitor a group common physical downlink control channel (GC PDCCH), a wireless device-specific PDCCH for multicast configuration information, or both. The base station may determine a schedule for transmitting multicast communications to the wireless device based on a capability reported by the wireless device, and may transmit to the wireless device an indication of whether a transport block for GC multicast communications including services for multicast communications will be scheduled by the GC PDCCH, the wireless device-specific PDCCH, or both. The base station may transmit, and the wireless device may receive, the multicast communications according to the multicast configuration information and the schedule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor, using a first physical downlink control channel (PDCCH) monitoring behavior, for a first downlink control information (DCI) format that indicates a set of resources associated with at least one of a cross component carrier (CC) scheduling or a multiple CC scheduling associated with a first CC and a second CC. The UE may monitor, using a second PDCCH monitoring behavior based at least in part on a determination that a PDCCH monitoring behavior switch condition is satisfied, for a second DCI format. Numerous other aspects are provided.
