Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a group of transmission configuration indicator states including a first subset associated with a first bandwidth part and a second subset associated with a common frequency resource. The UE may determine, based on the group of transmission configuration indicator states, a transmission configuration indicator state list arrangement indicating a first state list associated with the first bandwidth part and a second state list associated with the common frequency resource. The UE may select, based on the transmission configuration indicator state list arrangement, a transmission configuration indicator state sharing scheme or a transmission configuration indicator state separation scheme. The sharing scheme may include at least one transmission configuration indicator state that may be common between a unicast transmission configuration and a multicast transmission configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling that indicates one or more parameters pertaining to reception of paging early indications (PEIs). The UE may receive a PEI from the base station in accordance with the one or more parameters. The UE may determine, based on the PEI, whether the UE is scheduled to receive a multicast paging message from the base station in a subsequent paging occasion (PO). If the UE is scheduled to receive a multicast paging message, the UE may monitor for the multicast paging message in the subsequent PO. Otherwise, the UE may enter a low-power state during the subsequent PO, which may result in greater power savings at the UE. Aspects of the present disclosure may provide for improved multicast paging operations between the UE and the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).

Abstract: Methods, systems, and devices for wireless communications are described. A method for wireless communication at a user equipment (UE) may include: receiving a multicast bandwidth part configuration for multicast communications between a base station and the UE, where the multicast bandwidth part configuration includes a maximum number of multiple-input, multiple-output layers to be used for the multicast communications; establishing a multicast link with the base station for multicast communications; determining to use a reduced number of antennas for multicast reception than the number of antennas used for unicast reception, or determining that the UE is able to decode the multicast communications prior to a remaining portion of the multicast communications; and receiving the multicast communications via the reduced number of antennas, or reducing the radio frequency power prior to completion of a number of repetitions or retransmissions of the multicast communications.

Abstract: Methods, systems, and devices for wireless communications are described. Transport blocks may be scheduled using a single downlink control information (DCI) message. A wireless device may identify mapping pattern for mapping the transport blocks and repetitions of the transport blocks to communication resources. Mapping the transport blocks, or determining a mapping of the transport blocks, to communication resources may include partitioning the communication resources into subunits, where each subunit includes resources spread across each subband of a frequency hopping pattern and at least one instance of each of the scheduled transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may monitor a pre-wakeup window during an inactive duration of a multicast discontinuous reception (DRX) cycle that includes multiple active durations and multiple inactive durations. The UE may receive, in the pre-wakeup window, a wakeup signal that indicates a quantity of the active durations in the multicast DRX cycle that the UE is to monitor and the UE may monitor the indicated quantity of active durations for multicast signals for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first synchronization signal for synchronizing with a cell, the first synchronization signal transmitted at a first periodicity by a base station serving the cell. The UE may then receive, subsequent to the synchronizing, a second synchronization signal for resynchronizing with the cell. In some cases, the second synchronization signal may be transmitted by the base station according to a second periodicity that is different from the first periodicity. In some cases, the second synchronization signal may include a plurality of repetitions of a first sequence that is based at least in part on a cell identifier of the cell. The UE may communicate over the cell with the base station based at least in part on the resynchronizing.

Abstract: Methods, systems, and devices for wireless communications are described. A set of reference signal resources that are configured for sounding reference signal transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of reference signal resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel and transmit sounding reference signals over one of the shared reference signal resources that is associated with the set of channel state information determined by the UE. A base station that receives the sounding reference signal may transmit a subsequent multicast transmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied sounding reference signal resource.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive signaling indicating a set of multicast configurations for a set of multicast modes supported by the UE. Each multicast mode of the set of multicast modes may be associated with one or more radio resource control (RRC) states. The UE may determine a multicast configuration of the set of multicast configurations based on an RRC state according to which the UE is operating. The UE may receive, while operating according to the RRC state, multicast data according to the determined multicast configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control message including a first parameter and a second parameter. The first parameter may identify a first uplink control channel resource set for a first type of UE. The second parameter may identify a second uplink control channel resource set for a second type of UE. In some cases, a UE may receive the control message before receiving configuration information identifying a uplink control channel resource configuration. In some cases, a UE may optionally select an uplink control channel resource set based at least in part on the control message and a type of the UE. Also, a UE may transmit on an uplink using a communication configuration associated with the selected uplink control channel resource set. Numerous other aspects are provided.
