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: Aspects presented herein may enable a base station to map one or more DMRSs to one or more REs of a slot based on the locations of one or more CRSs in the slot and/or based on whether at least one DMRS overlaps with at least one CRS. In one aspect, the base station maps PDCCH DMRS of a first RAT to a CORESET based on whether CRS of a second RAT overlaps at least partially with the CORESET. The base station transmits the PDCCH DMRS mapped to the CORESET.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, while the UE is in wireless communications with a first serving cell supported by a base station, an indication to activate or deactivate a second serving cell supported by the base station. The UE may receive a reference signal from the base station via the first serving cell, the reference signal received a duration of time after receipt of the indication, where the duration of time is an interruption period for the wireless communications with the first serving cell. The UE may then resume the wireless communications with the first serving cell based on the interruption period ending at receipt of the reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A device may identify a transport block (TB) size for a TB that is scheduled across a set of component carriers (CCs) including a first CC and a second CC. The TB may include a first code block (CB) and a second CB. The device may rate match the TB with the set of CCs. Based on the rate matching, the device may identify redundancy portions of the first CB and redundancy portions of the second CB. The device may allocate a first redundancy portion of the first CB and a first redundancy portion of the second CB to the first CC, and may allocate a second redundancy portion of the first CB and a second redundancy portion of the second CB to the second CC. The device may transmit the TB over the set of CCs based on the allocating.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control information (DCI) message to one or more user equipments (UEs) scheduling a multicast data message in a multicast downlink shared channel, the DCI message indicating a feedback process identifier (ID) for the multicast data message. The base station may transmit an additional DCI message to a UE scheduling a retransmission of the multicast data message in a unicast downlink shared channel and indicating a feedback process ID for the retransmission of the multicast data message. The feedback process ID for the retransmission may be the same as, or different from, the initial transmission of the multicast data message. The UE may transmit feedback for the multicast data message based on receiving the initial transmission of the multicast data or the retransmission of the multicast data and the feedback process IDs.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may transmit system information indicating multiple multicast-broadcast network areas, and may further provide configuration information for each multicast-broadcast network area indicating a location of multicast scheduling information (MSI). The MSI may include an indication of frequency resources on which to receive broadcast or multicast services. The MSI may indicate specific services for an multicast-broadcast network area that are provided via the different frequency resources (for example, different cells, carriers, channels, among other examples). In some examples, the base station may schedule broadcast or multicast services across frequency resources via semi-persistent scheduling. The MSI may indicate a redundancy version configuration (for example, time and frequency patterns for combined redundancy version broadcast transmissions).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling, such as a control message or radio resource control (RRC) signaling, from a base station indicating a time interval over which to determine available power headroom relative to a transmission power threshold. The UE may calculate the available power headroom relative to the transmission power threshold as a function of UE transmission power during the time interval. The UE may transmit a power headroom report in an uplink transmission to the base station, the power headroom report indicating the calculated available power headroom. The base station may schedule one or more uplink messages at the UE according to the available power headroom.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a base station may transmit an indication of a pre-compensation timing value for transmission of a random access message by an aerial user equipment (UE), the random access message part of a random access procedure between the base station and the aerial UE when the aerial UE is in a connected state. The pre-compensation timing value may be based on a location of the aerial UE. In some examples, the base station may monitor a set of random access resources associated with the pre-compensation timing value and the aerial UE for the random access message, and the aerial UE may transmit the random access message using a first random access resource of a set of random access resources associated with the pre-compensation timing value and the aerial UE.
