Abstract: This disclosure provides systems, methods and apparatus for a signaling mechanism associated with activating a secondary cell (SCell) for uplink control information (UCI), including under circumstances in which the SCell is deactivated and belongs to a timing advance group (TAG) lacking a valid timing advance (TA) value. In one aspect, a user equipment (UE) and one or more components of a network entity may employ a signaling mechanism for establishing an SCell as a PUCCH-SCell in scenarios in which the PUCCH-SCell belongs to a secondary TAG (sTAG) lacking a valid TA value. The signaling mechanism may include signaling to directly provide the network entity with beam measurement information associated with one or more SCells of the sTAG or may include singling that the network entity may use to derive the beam measurement information associated with the one or more SCells of the sTAG.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARQ) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

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 receiving, from a base station, control signaling identifying a semi-persistent scheduling (SPS) configuration indicating resources for a first control channel and resources for a group-common downlink shared channel corresponding to the first control channel. The UE may receive, on resources for a second control channel, downlink control information including an indication for determining a feedback process identifier associated with the group-common downlink shared channel of the SPS configuration. The UE may monitor for signals on the group-common downlink shared channel of the SPS configuration based on the indicated feedback process identifier.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide a base station receiving an indication from a core network to serve multicast/broadcast traffic to one or more UEs. The base station may select a radio bearer mode from a plurality of radio bearer modes for delivery of the multicast/broadcast traffic to at least one UE of the one or more UEs. For example, the base station may select a multicast/broadcast only mode, a mixed multicast/broadcast mode and unicast mode, or a unicast mode for service of the traffic. Dependent on the selected mode and/or quality of service, the base station may select a dedicated radio bearer (DRB) for communication of the traffic in a unicast mode (e.g., to a particular UE) or a multicast radio bearer (MRB) for communication of the traffic in a broadcast/multicast mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an acknowledgment feedback configuration for providing feedback for semi-persistent scheduling (SPS) downlink shared channels (e.g., SPS group-common physical downlink shared channels (PDSCHs), SPS unicast PDSCHs, etc.). For example, the acknowledgment feedback configuration may include separate resources for transmitting acknowledgment feedback for unicast downlink shared channels and for transmitting acknowledgment feedback for group-common downlink shared channels or may include common resources for transmitting acknowledgment feedback for both unicast downlink shared channels and group-common downlink shared channels. In some examples, the UE may multiplex acknowledgment feedback for a set of group-common downlink shared channels with additional acknowledgment feedback for other downlink channels.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support uplink (UL) transmit (Tx) switch operations. In a first aspect, a method of wireless communication includes transmitting a user equipment (UE) capability that indicates multiple bands including a first set of bands and a second set of bands, each of the first set of bands and the second set of bands available for a UL Tx switch configuration. The first set of bands may be a pair of bands or a group of one or more bands. The method also includes receiving the UL Tx switch configuration for the first set of bands or the second set of bands, and transmitting an uplink message via the first set of bands or the second set of bands indicated by the UL Tx switch configuration. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling configuring the UE with a plurality of component carriers (CCs) for communicating with a base station and a semi-persistent resource allocation of a resource for each CC of the plurality of CCs. The UE may identify an availability indicator that indicates availability of the resource of the semi-persistent resource allocation on each CC of the plurality of CCs. The UE may communicate a data transmission via at least a subset of the plurality of CCs based at least in part on the availability indicator.
