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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a channel state information reference signal for a downlink cell associated with a first physical uplink control channel (PUCCH) group. The UE may report measurement information associated with channel state information reference signal using an uplink cell of a second PUCCH group associated with the first PUCCH group. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) transmissions with different reliability levels are provided. A user equipment (UE) receives, from a base station (BS), a negative acknowledgement (NACK) transmission configuration. The UE receives, from the BS, a data transmission. The UE transmits, to the BS, a physical uplink control channel (PUCCH) signal including a NACK for the data transmission based on the received NACK transmission configuration. Other aspects and features are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a trigger state associated with a configuration for receiving one or more secondary cell (SCell) activation reference signals. The UE may receive the one or more SCell activation reference signals based at least in part on the configuration. Numerous other aspects are described.

Abstract: Some aspects of the present disclosure disclose methods and systems related to the use of a periodic reference signal to activate a secondary cell. For example, a user equipment may receive, from a base station on a primary cell, an activation command configured to activate a secondary cell. The user equipment may also receive, from the base station and on the primary cell, a signal indicating an availability of a periodic reference signal on the secondary cell, the periodic RS being for use in activating the secondary cell. The user equipment may then, in response to receiving the signal, perform a tracking function to activate the secondary cell.

Abstract: A shared control region is provided for enhanced dynamic spectrum sharing between a first radio access technology (e.g., LTE) and a second radio access technology (e.g., NR). The shared control region is resource element mapped according to a resource element mapping for the first radio access technology (RAT) and includes pilot signals for the first RAT. The shared control region also includes control information for a user equipment in the second RAT.

Abstract: Mechanisms for rate matching a downlink communication channel in a multi-radio access technology (RAT) communication scenario are described. In one aspect, a method for wireless communication performed by a base station (BS) includes rate matching, based on a rate matching pattern indicating a plurality of reserved resource elements, a downlink (DL) communication channel. The method further includes transmitting, to a user equipment (UE) on one or more antenna ports, a DL communication in the rate matched DL communication channel. The method further includes transmitting, on the one or more antenna ports, one or more signals in the plurality of reserved resource elements. The one or more signals transmitted in the plurality of reserved resource elements may allow UEs associated with other RATs to estimate the rate matched DL communication channel.
